Connectors & Terminals

Connections & Terminations

Wire harnesses and cable assemblies are essential components of many electrical systems. One critical aspect of wire harness and cable assembly design is the selection of the right connector and terminal types. In this blog post, we will explore the different types of connectors and terminals in wire harnesses and cable assemblies.

Connectors:

1. Circular Connectors

Circular connectors are a popular choice for many applications because they are easy to use and provide a secure connection. In harsh environments, such as those in the military and aerospace industries, these assemblies are a great choice.  Circular connectors are available in a range of sizes and configurations, with options for different numbers of contacts, contact arrangements, and locking mechanisms.

2. Rectangular Connectors

Rectangular connectors are another popular choice for many applications. In automotive and industrial applications, they are easy to use and provide a secure connection. Rectangular connectors are available in a range of sizes and configurations, with options for different numbers of contacts, contact arrangements, and locking mechanisms.

3. Coaxial Connectors

Coaxial connectors are perfect for applications that require high-frequency signals, such as in the telecommunications and aerospace industries. They maintain the integrity of the signal by providing a consistent impedance between the source and the load. Coaxial connectors are available in a range of sizes and configurations, with options for different impedance values, contact arrangements, and locking mechanisms.

Terminals:

1. Crimp Terminals

Crimp terminals are a popular choice for many applications because they are easy to use and provide a secure connection. They are prominent in automotive and industrial applications. Crimp terminals are available in a range of sizes and configurations. They also have options for different wire gauges, insulation types, and termination methods.

2. Solder Terminals

Solder terminals are common in applications with secure, high-quality connections. In the aerospace and military industries, reliability is critical. Solder terminals are available in a range of sizes and configurations, with options for different wire gauges, insulation types, and termination methods.

3. Insulation Displacement Terminals (IDTs)

IDTs are a type of terminal that allows a wire insertion into the terminal without the need for stripping the insulation. IDTs are common in applications where the wire must be terminated quickly and easily. They are common in automotive and industrial applications. IDTs are available in a range of sizes and configurations, with options for different wire gauges, insulation types, and termination methods.

In conclusion, selecting the right connectors and terminals for wire harnesses and cable assemblies is critical to ensuring that the assembly is reliable and meets the requirements of the application. Circular and rectangular connectors are popular choices for many applications, while coaxial connectors are used for high frequency signals. Crimp, solder, and IDT terminals are commonly used, each with its own advantages depending on the specific requirements of the application. By selecting the right connector and terminal types, you can ensure that your wire harnesses and cable assemblies are reliable and meet the needs of your application.
