1-1986725-0 Application Field and Working Principle

Terminal blocks, headers, plugs and sockets are all used as electrical connectors in various electronic devices and systems. These components are typically used for the connection of wires, cables, power supplies and other components. They are typically used in communication, industrial and medical electronic devices and equipment.

Types of Terminal Blocks

Terminal blocks come in several different types, including male and female terminal blocks, pluggable terminal blocks, PCB terminal blocks, screwless terminal blocks, and DIN rail terminal blocks, among others. Male and female terminal blocks are available as both insulated and non-insulated types, and have a pin or terminal that sets inside the connecting block in order to ensure a secure connection. Pluggable terminal blocks provide a quick and easy connection for wires and cables. PCB terminal blocks have pins that pass through a board in order to create a direct connection between a circuit board and a wire or cable. Screwless terminal blocks create a secure connection without the use of screws. DIN rail terminal blocks are used when a universal, wide-range connection is needed, and feature a two- or three-pole connection.

Features of Terminal Blocks

Some of the features of various types of terminal blocks include multiple connection options, current and voltage ratings, UL/CSA approvals, color coding, and ease of installation. Multiple connection options are available with different types of terminal blocks. Depending on the type of terminal block, they may have different ratings for current and voltage. All types of terminal blocks should have UL/CSA approvals for safety and reliability. Color coding is available with many types of terminal blocks for quick and easy wiring. And lastly, all types of terminal blocks should be easy to install and come with connecting hardware if required.

Application Field of Terminal Blocks

Terminal blocks are used in a wide variety of applications, including consumer electronics, industrial automation, medical and biomedical electronics, communications and networks, and automotive electronics, among others. Terminal blocks are used in these applications in order to provide a safe and reliable connection between components, devices, and systems. They are also used to provide a secure connection between wires and cables, and to indicate connections and disconnections. In addition, terminal blocks are used to provide an insulated connection, protect against electric shock, direct current, and other hazards.

Working Principle of Terminal Blocks

The working principle of most types of terminal blocks is based on a two-pole connection, which consists of a positive and a negative contact, and is typically referred to as a fork and blade connection. The positive and negative contacts are connected by a conductor, and the wires or cables are then connected to the contacts. The connection is secured by a nut and bolt, snap-in clip, or other type of secure fastening. The connection is then sealed and insulated to ensure an air and water tight seal.
