Terminal Blocks - Headers, Plugs and Sockets

Terminal blocks, also known as headers, plugs, or sockets, are electrical connection pieces designed to break or terminate a current flow or electric wiring. A wide variety of terminal blocks are available, ranging from simple, low-current options for wiring harnesses to 2500/4000-volt connections for power transmission applications. A wide range of plugs and sockets is also available, so the right connection method can be chosen for each specific application.

The primary purpose of terminal blocks is to provide a way to securely and reliably break or terminate a current flow or wire connection. They are designed to be easily used and replaceable, and the connections they create are meant to withstand the test of time and the harshest of weather conditions. Most terminal blocks have backplate attachment points so they can be quickly and easily replaced without the need for additional tools or installation processes.

Terminal blocks are typically made from a variety of materials including, but not limited to, aluminum, brass, copper, and stainless steel. The specifications of each individual component must be taken into consideration when selecting a terminal block, as different materials can provide different levels of electrical and mechanical performance depending on the application. Terminal blocks are typically rated for a certain voltage or amperage and must not be exceeded.

There are a variety of terminal block types and configurations used in various applications. Connectors typically range in size from 2.5mm to 28mm, with higher-current applications requiring larger terminal blocks. Terminals come in a variety of styles including crimp, multi-crimp, insulation displacement, plug-in, and through-hole connections. Each connection type provides different properties depending on the amount of current and voltage being transferred and the material used in the terminal blocks.

1941 terminal blocks are a type of terminal block designed for military and aerospace applications. They are designed to provide very high-voltage and current capabilities in a relatively compact size. These terminal blocks are typically designed to withstand both extreme temperatures and harsh weather conditions, making them ideal for use in the aerospace and military fields. They are commonly used in aircraft wiring applications and on satellites, as they provide excellent electrical performance and reliability.

The 1941 specification terminal blocks are typically available in 2- and 3-pole variants and range in voltage/current ratings from 600 to 4000 volts and from 100 to 400 amperes. The terminal blocks include a variety of contact designs to meet various current/voltage requirements, and the connection hardware can be customized to fit specific application requirements.

The working principle of a terminal block is relatively simple. Current is conducted between two or more electrical contact points, which are connected via a conductor (typically copper or aluminum). The contact points are separated from the conductor by an insulator, and the device is designed to break or terminate the current flow.

In conclusion, terminal blocks - headers, plugs and sockets - are electrical connection pieces designed to break or terminate a current flow or electric wiring in a wide range of applications. 1941 terminal blocks are a type of terminal block designed for military and aerospace applications, and the working principle is relatively simple. When selecting a terminal block type for a specific application, one must take into consideration the application’s specifications as well as the individual component ratings.
