Terminal blocks are electrical connection blocks that allow two or more conductors to be interconnected or securely separated without soldering. These interconnection blocks are very widely used in almost every type of electrical applications and are usually encountered in the form of a metal plate which can be secured with screws or some other mechanism. They allow for the connection of various types of wires and cables in a variety of sizes depending on the type of terminal block being used.

Terminal blocks used for wire-to-board connections, are primarily utilized in the automotive, industrial and transportation markets. These types of blocks enable a reliable and secure connection to be provided between printed circuit boards (PCB‘s) and wire bundles/harnesses, eliminating the need for soldering. They typically include communication points for the connection of signals and power lines directly to the board.

Terminal blocks that are used in wire-to-board connections generally have two main components - a terminal post and a connector body. The terminal post provides the structural integrity of the block and the connector body houses the contacts. These blocks are designed to withstand direct current levels up to 1891399 amps (A). There are various types of connections such as single and double-wire push-in, cage-clamp, and screw terminals available on the market.

The working principle behind these terminal blocks is very simple. The conductor to be connected is stripped of insulation at the required length and inserted into a connector body.Various designs of connection bodies make this possible. On the insertion of the conductor, the contacts engage and provide an electrical connection. The terminals are easily maintained using a polarity reversal mechanism. The reversal mechanism allows for polarity swap between connecting line and contacts.

The terminal blocks used for wire-to-board connections normally have a good resistance to shock and vibration and offer a secure connection from the terminal to the board with solderless mounting. The design provides terminals that are self-cleaning, dust-proof, self-aligning, with a fast and reliable connection. This flexibility, paired with their compact size, makes them a great choice for a wide range of industrial and commercial applications.

Terminal blocks used for wire-to-board connections are very secure and effective at protecting sensitive circuits from damage. The blocks also provide an economical solution with a quick and easy installation along with flexibility in cabling. This makes them your best choice for applications requiring the connection of wiring between a PCB and a wiring harness or wire bundle.
