The Basics of Connectors

2. Objectives

The objective of this learning module is to provide you with the essentials of connector technology. You will first learn the purpose, function, and components of a connector. In the later sections, you will gain a deeper understanding of the types, materials, features, and applications of PCB, Card/Slot and I/O connectors.

Upon completion of this module, you will be able to:

Define what connectors are and the purpose they serve;
Discuss the primary functions of a connector;
Describe the anatomy of a connector;
Identify the most common types of connectors.

3. Definition

What is a connector? Is a connector simply a means to connect two electrical points of a circuit, or is its purpose broader in scope? To understand the purpose of a connector, let us consider a jumper wire. Is a typical jumper wire – one that connects circuit components together on a prototyping breadboard – a connector?

A jumper wire can connect two points of a circuit together, but lacks the mechanical integrity or environmental protection required in an end-product that is subjected to vibrations, abuse, corrosion or water sprays. In this respect, a connector provides more than a means of electrical connection, but should offer a durable mechanical or mating connection as well. So, maybe a jumper wire falls short as a connector.

If a jumper wire isn’t a connector, then what exactly is? Let’s look at the definition of connector to find out:

A connector is a device that is capable of connecting two circuit points, signals, or sub-systems with electrical integrity, mechanical durability, environmental protection and safety.

Electrical Integrity - when connectors mate two points of a circuit with a very low contact resistance and provide protection from electromagnetic interference (EMI) and/or electrostatic discharge (ESD).
Mechanical Durability - when a connector can withstand vibrations or environmental abuse without causing a failure in electrical integrity.
Environmental Protection - when a connector’s design meets the IP (Ingress Protection) ratings defined in the international standard EN/IEC 60529 for preventing the ingress of water, dust, debris, and other contaminants that would otherwise interfere with the electrical integrity of the connection.
Safety - when a connector is designed with features that eliminate personnel hazards, or the risk of fire, shock or electrocution.

4. Function

To understand the function of a connector, let’s imagine for a moment a world without connectors. What would be the practical outcome of such a scenario?

In such a world, all electronic components, sub-assemblies and electrical power would be connected by bare metal wiring. This means everything would be soldered, mechanically attached or twisted together. Doesn’t sound convenient, does it?

It would be pretty hard to design products with high-circuit densities in a “No Connectors Allowed” world. Smart phones would probably be a lot bigger. And forget about portable charging stations or even your handy power adapter!

What about electrical safety? Would a ”No Connectors Allowed” world be safer for a user? Could you safely connect the 120/230V mains to your home appliance without sparks flying? (Probably not!) It’s time to go back to a world with connectors and learn the primary functions of a connector.

The primary functions of a connector are:

Quick Connection/Disconnection: Connectors provide a safe, quick and convenient means for connecting and disconnecting components, modules, systems and sub-assemblies during prototyping, manufacturing, installation, operation, or maintenance.
Efficient Manufacturing: Connectors allow for the efficient production of products by eliminating many time-consuming tasks such as soldering.
Easy Upgrades/Configurations: Connectors enable users to easily upgrade products or quickly configure new devices for these products.
Eliminate Safety Hazards: Connectors shield users from hazardous currents that could pose a shock or electrocution hazard.

5. The Anatomy of a Connector

There are many types and styles of connectors, yet they all share common characteristics. In this section, we will discuss the common components and features of a connector.

The three main parts of a connector are:

Housing
Shell
Contact

- 5.1 Description of a Housing

The housing is the component that provides a connector the mechanical durability, environmental protection and electrical insulation for the contact terminals.

Connector housings have the following characteristics:

Materials: Housings are made of stabilized, heat resistant, self-extinguishing thermoplastic material.
Locking: Housings often have a locking tab to prevent connector housing halves from disconnecting and interrupting a circuit.
Polarization: Housings are polarized to ensure the connector halves are mated correctly.
Keying: Housings are keyed or arranged so only compatible contacts or circuits can be mated with one another.
Environmental Protection: Housing often have shrouds or seals (depending upon the specifications of a connector) to prevent the ingress of dust, moisture, chemicals and other contaminants that could degrade the electrical integrity of the connection.
Mounting: Housings can be mounted in a variety of ways, including PCB, panel, and wire-to-wire configurations.
Fire Safety: High-performance composite materials help meet the low smoke, toxicity and flammability (UL 94V-0 rated) requirements of the application.

- 5.2 Description of a Shell

The shell encloses the connector housing thereby offers added strength and protection to the housing. Since shells are made of a nickel-plated, zinc alloy, they also offer excellent corrosion resistance.

- 5.3 Description of Contacts and Terminals

The contact consists of highly conductive material with very low resistance that allows the easy flow of electrical current through the two mated contacts.

While the contact is the point where circuit current flows, the terminal is the means by which the contact is attached (or terminated) to a circuit’s conductor. Often times the functions of both the contact and terminal are combined in one device. In this case, the word terminal and contact maybe used interchangeably.

Contact terminals have the following characteristics:

Materials: A variety of materials or alloys are used for electrical contacts and terminals based upon cost, electrical and thermal properties, resistance to oxidation (corrosion) and durability. The most common contact metals include: brass, phosphor bronze, and high copper alloy. Contacts are often plated for added strength, better conductivity and corrosion resistance. Plating materials include gold, silver nickel, tin, and palladium-nickel.
Types: Contacts are constructed in the form of insertable/removable pins and sockets (informally referred to as “male” and “female,” respectively).
Locking: Terminals often have locking wing tabs to securely hold the terminal in the connector’s housing.

- 5.4 Description of Terminations

Terminations are the manner by which the circuit’s conductors are attached to the connector’s contact terminals. The quality of the terminations is critical to the proper functioning of the circuits connected by a connector.

Electrically sound terminations maintain a desirable low contact resistance at the point of connection. Conversely, terminations that are not electrically sound —opened, shorted, or high resistance points —can be detrimental to the proper functioning of the circuit. This is a particular concern in high vibration environments (industrial machinery or automotive applications).

The common types of terminations include:

AMPLIMITE* HDP-20 Connectors with Solder Cup Contacts

Solder Cup

a type of termination where individual circuit wires are soldered on the connector’s “cup” terminals.

TE Connectivity’s AMP Wire-To-Board Connector, AMP CT Series, Crimp, Receptacle

2. Objectives

Upon completion of this module, you will be able to:

Define what connectors are and the purpose they serve;
Discuss the primary functions of a connector;
Describe the anatomy of a connector;
Identify the most common types of connectors.

3. Definition

If a jumper wire isn’t a connector, then what exactly is? Let’s look at the definition of connector to find out:

A connector is a device that is capable of connecting two circuit points, signals, or sub-systems with electrical integrity, mechanical durability, environmental protection and safety.

Electrical Integrity - when connectors mate two points of a circuit with a very low contact resistance and provide protection from electromagnetic interference (EMI) and/or electrostatic discharge (ESD).
Mechanical Durability - when a connector can withstand vibrations or environmental abuse without causing a failure in electrical integrity.
Environmental Protection - when a connector’s design meets the IP (Ingress Protection) ratings defined in the international standard EN/IEC 60529 for preventing the ingress of water, dust, debris, and other contaminants that would otherwise interfere with the electrical integrity of the connection.
Safety - when a connector is designed with features that eliminate personnel hazards, or the risk of fire, shock or electrocution.

4. Function

To understand the function of a connector, let’s imagine for a moment a world without connectors. What would be the practical outcome of such a scenario?

The primary functions of a connector are:

Quick Connection/Disconnection: Connectors provide a safe, quick and convenient means for connecting and disconnecting components, modules, systems and sub-assemblies during prototyping, manufacturing, installation, operation, or maintenance.
Efficient Manufacturing: Connectors allow for the efficient production of products by eliminating many time-consuming tasks such as soldering.
Easy Upgrades/Configurations: Connectors enable users to easily upgrade products or quickly configure new devices for these products.
Eliminate Safety Hazards: Connectors shield users from hazardous currents that could pose a shock or electrocution hazard.

5. The Anatomy of a Connector

There are many types and styles of connectors, yet they all share common characteristics. In this section, we will discuss the common components and features of a connector.

The three main parts of a connector are:

Housing
Shell
Contact

- 5.1 Description of a Housing

The housing is the component that provides a connector the mechanical durability, environmental protection and electrical insulation for the contact terminals.

Connector housings have the following characteristics:

Materials: Housings are made of stabilized, heat resistant, self-extinguishing thermoplastic material.
Locking: Housings often have a locking tab to prevent connector housing halves from disconnecting and interrupting a circuit.
Polarization: Housings are polarized to ensure the connector halves are mated correctly.
Keying: Housings are keyed or arranged so only compatible contacts or circuits can be mated with one another.
Environmental Protection: Housing often have shrouds or seals (depending upon the specifications of a connector) to prevent the ingress of dust, moisture, chemicals and other contaminants that could degrade the electrical integrity of the connection.
Mounting: Housings can be mounted in a variety of ways, including PCB, panel, and wire-to-wire configurations.
Fire Safety: High-performance composite materials help meet the low smoke, toxicity and flammability (UL 94V-0 rated) requirements of the application.

- 5.2 Description of a Shell

- 5.3 Description of Contacts and Terminals

The contact consists of highly conductive material with very low resistance that allows the easy flow of electrical current through the two mated contacts.

Contact terminals have the following characteristics:

Materials: A variety of materials or alloys are used for electrical contacts and terminals based upon cost, electrical and thermal properties, resistance to oxidation (corrosion) and durability. The most common contact metals include: brass, phosphor bronze, and high copper alloy. Contacts are often plated for added strength, better conductivity and corrosion resistance. Plating materials include gold, silver nickel, tin, and palladium-nickel.
Types: Contacts are constructed in the form of insertable/removable pins and sockets (informally referred to as “male” and “female,” respectively).
Locking: Terminals often have locking wing tabs to securely hold the terminal in the connector’s housing.

- 5.4 Description of Terminations

The common types of terminations include:

AMPLIMITE* HDP-20 Connectors with Solder Cup Contacts

Solder Cup

a type of termination where individual circuit wires are soldered on the connector’s “cup” terminals.

TE Connectivity’s AMP Wire-To-Board Connector, AMP CT Series, Crimp, Receptacle

2. Objectives

Upon completion of this module, you will be able to:

Define what connectors are and the purpose they serve;
Discuss the primary functions of a connector;
Describe the anatomy of a connector;
Identify the most common types of connectors.

3. Definition

If a jumper wire isn’t a connector, then what exactly is? Let’s look at the definition of connector to find out:

A connector is a device that is capable of connecting two circuit points, signals, or sub-systems with electrical integrity, mechanical durability, environmental protection and safety.

Electrical Integrity - when connectors mate two points of a circuit with a very low contact resistance and provide protection from electromagnetic interference (EMI) and/or electrostatic discharge (ESD).
Mechanical Durability - when a connector can withstand vibrations or environmental abuse without causing a failure in electrical integrity.
Environmental Protection - when a connector’s design meets the IP (Ingress Protection) ratings defined in the international standard EN/IEC 60529 for preventing the ingress of water, dust, debris, and other contaminants that would otherwise interfere with the electrical integrity of the connection.
Safety - when a connector is designed with features that eliminate personnel hazards, or the risk of fire, shock or electrocution.

4. Function

To understand the function of a connector, let’s imagine for a moment a world without connectors. What would be the practical outcome of such a scenario?

The primary functions of a connector are:

Quick Connection/Disconnection: Connectors provide a safe, quick and convenient means for connecting and disconnecting components, modules, systems and sub-assemblies during prototyping, manufacturing, installation, operation, or maintenance.
Efficient Manufacturing: Connectors allow for the efficient production of products by eliminating many time-consuming tasks such as soldering.
Easy Upgrades/Configurations: Connectors enable users to easily upgrade products or quickly configure new devices for these products.
Eliminate Safety Hazards: Connectors shield users from hazardous currents that could pose a shock or electrocution hazard.

5. The Anatomy of a Connector

There are many types and styles of connectors, yet they all share common characteristics. In this section, we will discuss the common components and features of a connector.

The three main parts of a connector are:

Housing
Shell
Contact

- 5.1 Description of a Housing

The housing is the component that provides a connector the mechanical durability, environmental protection and electrical insulation for the contact terminals.

Connector housings have the following characteristics:

Materials: Housings are made of stabilized, heat resistant, self-extinguishing thermoplastic material.
Locking: Housings often have a locking tab to prevent connector housing halves from disconnecting and interrupting a circuit.
Polarization: Housings are polarized to ensure the connector halves are mated correctly.
Keying: Housings are keyed or arranged so only compatible contacts or circuits can be mated with one another.
Environmental Protection: Housing often have shrouds or seals (depending upon the specifications of a connector) to prevent the ingress of dust, moisture, chemicals and other contaminants that could degrade the electrical integrity of the connection.
Mounting: Housings can be mounted in a variety of ways, including PCB, panel, and wire-to-wire configurations.

2. Objectives

Upon completion of this module, you will be able to:

Define what connectors are and the purpose they serve;
Discuss the primary functions of a connector;
Describe the anatomy of a connector;
Identify the most common types of connectors.

3. Definition

If a jumper wire isn’t a connector, then what exactly is? Let’s look at the definition of connector to find out:

A connector is a device that is capable of connecting two circuit points, signals, or sub-systems with electrical integrity, mechanical durability, environmental protection and safety.

Electrical Integrity - when connectors mate two points of a circuit with a very low contact resistance and provide protection from electromagnetic interference (EMI) and/or electrostatic discharge (ESD).
Mechanical Durability - when a connector can withstand vibrations or environmental abuse without causing a failure in electrical integrity.
Environmental Protection - when a connector’s design meets the IP (Ingress Protection) ratings defined in the international standard EN/IEC 60529 for preventing the ingress of water, dust, debris, and other contaminants that would otherwise interfere with the electrical integrity of the connection.
Safety - when a connector is designed with features that eliminate personnel hazards, or the risk of fire, shock or electrocution.

4. Function

To understand the function of a connector, let’s imagine for a moment a world without connectors. What would be the practical outcome of such a scenario?

The primary functions of a connector are:

Quick Connection/Disconnection: Connectors provide a safe, quick and convenient means for connecting and disconnecting components, modules, systems and sub-assemblies during prototyping, manufacturing, installation, operation, or maintenance.
Efficient Manufacturing: Connectors allow for the efficient production of products by eliminating many time-consuming tasks such as soldering.
Easy Upgrades/Configurations: Connectors enable users to easily upgrade products or quickly configure new devices for these products.
Eliminate Safety Hazards: Connectors shield users from hazardous currents that could pose a shock or electrocution hazard.

5. The Anatomy of a Connector

There are many types and styles of connectors, yet they all share common characteristics. In this section, we will discuss the common components and features of a connector.

The three main parts of a connector are:

Housing
Shell
Contact

- 5.1 Description of a Housing

The housing is the component that provides a connector the mechanical durability, environmental protection and electrical insulation for the contact terminals.

Connector housings have the following characteristics:

Materials: Housings are made of stabilized, heat resistant, self-extinguishing thermoplastic material.
Locking: Housings often have a locking tab to prevent connector housing halves from disconnecting and interrupting a circuit.
Polarization: Housings are polarized to ensure the connector halves are mated correctly.
Keying: Housings are keyed or arranged so only compatible contacts or circuits can be mated with one another.
Environmental Protection: Housing often have shrouds or seals (depending upon the specifications of a connector) to prevent the ingress of dust, moisture, chemicals and other contaminants that could degrade the electrical integrity of the connection.
Mounting: Housings can be mounted in a variety of ways, including PCB, panel, and wire-to-wire configurations.
Fire Safety: High-performance composite materials help meet the low smoke, toxicity and flammability (UL 94V-0 rated) requirements of the application.

- 5.2 Description of a Shell

- 5.3 Description of Contacts and Terminals

The contact consists of highly conductive material with very low resistance that allows the easy flow of electrical current through the two mated contacts.

Contact terminals have the following characteristics:

Materials: A variety of materials or alloys are used for electrical contacts and terminals based upon cost, electrical and thermal properties, resistance to oxidation (corrosion) and durability. The most common contact metals include: brass, phosphor bronze, and high copper alloy. Contacts are often plated for added strength, better conductivity and corrosion resistance. Plating materials include gold, silver nickel, tin, and palladium-nickel.
Types: Contacts are constructed in the form of insertable/removable pins and sockets (informally referred to as “male” and “female,” respectively).
Locking: Terminals often have locking wing tabs to securely hold the terminal in the connector’s housing.

- 5.4 Description of Terminations

The common types of terminations include:

Connectors I: The Basics of Connectors

Sponsored by

1. Introduction

2. Objectives

Upon completion of this module, you will be able to:

Define what connectors are and the purpose they serve;

Discuss the primary functions of a connector;

Describe the anatomy of a connector;

Identify the most common types of connectors.

3. DefinitionBack to Top

If a jumper wire isn’t a connector, then what exactly is? Let’s look at the definition of connector to find out:

A connector is a device that is capable of connecting two circuit points, signals, or sub-systems with electrical integrity, mechanical durability, environmental protection and safety.

Mechanical Durability - when a connector can withstand vibrations or environmental abuse without causing a failure in electrical integrity.

Safety - when a connector is designed with features that eliminate personnel hazards, or the risk of fire, shock or electrocution.

4. FunctionBack to Top

To understand the function of a connector, let’s imagine for a moment a world without connectors. What would be the practical outcome of such a scenario?

The primary functions of a connector are:

Efficient Manufacturing: Connectors allow for the efficient production of products by eliminating many time-consuming tasks such as soldering.

Easy Upgrades/Configurations: Connectors enable users to easily upgrade products or quickly configure new devices for these products.

Eliminate Safety Hazards: Connectors shield users from hazardous currents that could pose a shock or electrocution hazard.

5. The Anatomy of a ConnectorBack to Top

There are many types and styles of connectors, yet they all share common characteristics. In this section, we will discuss the common components and features of a connector.

The three main parts of a connector are:

Housing

Shell

Contact

- 5.1 Description of a Housing

The housing is the component that provides a connector the mechanical durability, environmental protection and electrical insulation for the contact terminals.

Connector housings have the following characteristics:

Materials: Housings are made of stabilized, heat resistant, self-extinguishing thermoplastic material.

Locking: Housings often have a locking tab to prevent connector housing halves from disconnecting and interrupting a circuit.

Polarization: Housings are polarized to ensure the connector halves are mated correctly.

Keying: Housings are keyed or arranged so only compatible contacts or circuits can be mated with one another.

Mounting: Housings can be mounted in a variety of ways, including PCB, panel, and wire-to-wire configurations.

Fire Safety: High-performance composite materials help meet the low smoke, toxicity and flammability (UL 94V-0 rated) requirements of the application.

- 5.2 Description of a Shell

- 5.3 Description of Contacts and Terminals

The contact consists of highly conductive material with very low resistance that allows the easy flow of electrical current through the two mated contacts.

Contact terminals have the following characteristics:

Types: Contacts are constructed in the form of insertable/removable pins and sockets (informally referred to as “male” and “female,” respectively).

Locking: Terminals often have locking wing tabs to securely hold the terminal in the connector’s housing.

- 5.4 Description of Terminations

The common types of terminations include:

AMPLIMITE* HDP-20 Connectors with Solder Cup Contacts

Solder Cup

a type of termination where individual circuit wires are soldered on the connector’s “cup” terminals.

TE Connectivity’s AMP Wire-To-Board Connector, AMP CT Series, Crimp, Receptacle

Crimping

a type of termination that creates a secure and separable connection between the contacts and terminal wires.

TE Connectivity’s AMP Circular Plastic Connector, Series 1, PCB Mount

PCB Solder

a type of termination where the contact terminals are soldered directly onto a PCB via through-holes.

TE Connectivity 1735690-1 SAS Receptacle, Press-Fit

Press Fit

TE Connectivity’s AMP Mini USB, 2.0 Type A, Receptacle, Surface Mount

Surface Mount

a type of termination where the connector is mounted to the surface of a PCB and bonded to conductive pads via soldering.

TE Connectivity’s AMP Wire-To-Board Connector, AMPMODU Series, IDC Plug

Insulation Displacement Termination (IDC)

a type of termination that connects insulated wire without requiring the pre-stripping of the insulation.

1. Introduction

2. Objective

Upon completion of this module, you will be able to:

Define what connectors are and the purpose they serve;

Discuss the primary functions of a connector;

Describe the anatomy of a connector;

Identify the most common types of connectors.

3. DefinitionBack to Top

If a jumper wire isn’t a connector, then what exactly is? Let’s look at the definition of connector to find out:

A connector is a device that is capable of connecting two circuit points, signals, or sub-systems with electrical integrity, mechanical durability, environmental protection and safety.

Mechanical Durability - when a connector can withstand vibrations or environmental abuse without causing a failure in electrical integrity.

Safety - when a connector is designed with features that eliminate personnel hazards, or the risk of fire, shock or electrocution.

4. FunctionBack to Top

To understand the function of a connector, let’s imagine for a moment a world without connectors. What would be the practical outcome of such a scenario?

The primary functions of a connector are:

Efficient Manufacturing: Connectors allow for the efficient production of products by eliminating many time-consuming tasks such as soldering.

Easy Upgrades/Configurations: Connectors enable users to easily upgrade products or quickly configure new devices for these products.

Eliminate Safety Hazards: Connectors shield users from hazardous currents that could pose a shock or electrocution hazard.

5. The Anatomy of a ConnectorBack to Top

There are many types and styles of connectors, yet they all share common characteristics. In this section, we will discuss the common components and features of a connector.

The three main parts of a connector are:

Housing

Shell

Contact

- 5.1 Description of a Housing

The housing is the component that provides a connector the mechanical durability, environmental protection and electrical insulation for the contact terminals.

Connector housings have the following characteristics:

Materials: Housings are made of stabilized, heat resistant, self-extinguishing thermoplastic material.

Locking: Housings often have a locking tab to prevent connector housing halves from disconnecting and interrupting a circuit.

Polarization: Housings are polarized to ensure the connector halves are mated correctly.

Keying: Housings are keyed or arranged so only compatible contacts or circuits can be mated with one another.

Mounting: Housings can be mounted in a variety of ways, including PCB, panel, and wire-to-wire configurations.

Fire Safety: High-performance composite materials help meet the low smoke, toxicity and flammability (UL 94V-0 rated) requirements of the application.

- 5.2 Description of a Shell

- 5.3 Description of Contacts and Terminals

The contact consists of highly conductive material with very low resistance that allows the easy flow of electrical current through the two mated contacts.

Contact terminals have the following characteristics:

Types: Contacts are constructed in the form of insertable/removable pins and sockets (informally referred to as “male” and “female,” respectively).

Locking: Terminals often have locking wing tabs to securely hold the terminal in the connector’s housing.

- 5.4 Description of Terminations

The common types of terminations include:

AMPLIMITE* HDP-20 Connectors with Solder Cup Contacts

Solder Cup

a type of termination where individual circuit wires are soldered on the connector’s “cup” terminals.

TE Connectivity’s AMP Wire-To-Board Connector, AMP CT Series, Crimp, Receptacle
