Terminal Blocks - Headers, Plugs and Sockets are primarily used in the electrical and electronics industry, for connecting two conductors. This is generally referred to as T-block connectors as they look like a capital ‘T’. It is an integral part of wire-to-board and board-to-board connection system. The plugs and headers provide a secure electrical connection between two circuits, in a broad range of applications.

Terminal Blocks – Headers, Plugs and Sockets are normally found in power supplies, computer boards, interface I/O boards, commercial appliances, lighting, home automation systems and telecom system layers. They can also be used in security and access control systems, industrial plant automation, display boards, motor speed controllers, automotive industry, solar Inverters etc.

1038230000 Terminal Blocks – plugs and headers consist of two Parts. The first part (plug) of the T-block connector which is the male part, houses contacts that get connected to a source. The second part (header) which is the female part, is the output of the block connector and houses the receiving contacts. It consists of 2 kinds of connections, one is a terminal block connection and the other is a pin header connection.The pin header connection usually requires a Molex connector ·for insertion into the board. The Molex connector carries the ground (shield) wire, if required.

Working Principle:The working principle of Terminal Blocks – Headers, Plugs and Sockets is simple. The pins of the plug are inserted into the header and held in place with a clip or spring. When the connection is made, a conductive material inside the T-block connector forms an electrical connection between the pins of the plug and header. A small air gap is present between the pins of the plug and header, this helps to prevent any arching or sparking of electrical current which could lead to shorts or even fire hazards.

Terminal Blocks – Headers, Plugs and Sockets are made up of electrical insulation materials and different types of plating is used for various applications. Insulation materials such as PBT, PA66 or PPO are used in the construction of T-block connectors. The Plating used can be non-conductive nickel, zinc, gold or tin/lead. The terminal blocks are also usually available in UL and CSA approved versions, to ensure safety and to keep in step with the prevailing industry regulations.

Terminal Blocks – Headers, Plugs and Sockets are available in different shapes and counts. They are usually rated for different applications such as signal, power and high power applications. The signal transmission between T-blocks is via the resistive nature of the contacts in the block connectors. It is recommended that the same type of T-block connection system be chosen for all the applications. This is because different types and sizes of connectors have different properties that could interfere with signal transmission.

Terminal Blocks – Headers, Plugs and Sockets are widely used in power supplies, commercial appliances, lighting, home automation systems, telecom system layers, security and access control systems, industrial plant automation, display boards, motor speed controllers, automotive industry and solar inverters. They provide a secure connection between two circuits and are simple to use. It is important to choose the right terminals for the right application to ensure quality and longevity of the application.
