Terminal blocks are devices that provide quick and secure way to connect and disconnect electrical wires without having to solder them. Types of Terminal Blocks can be classified into two categories: Wire to Board and Board to Board.

Wire to Board Terminal Blocks are those that provide the necessary connection between electrical wires and PCBs (Printed Circuit Boards). A Wire to Board Terminal Block typically consists of a plastic base, conductive pins and a contact plate. The plastic base is usually made from a semi-rigid material, such as nylon or polystyrene. Conductive pins are made from copper or brass, and the contact plate is made from stamped or milled brass, copper or aluminum.

Wire to Board Terminal Blocks are typically used in applications which require a reliable connection between electrical wires and a PCB. They are commonly used in situations where multiple wires need to be connected to various points on a PCB. The conductive pins provide reliable electrical contact between the wires and the printed circuit board. Due to their low profile design, Wire to Board Terminal Blocks are also used in high density applications where space is limited.

The working principle of a Wire to Board Terminal Block is relatively straightforward. As mentioned above, the plastic base contains conductive pins which are inserted into the PCB. When a wire is inserted into the base of the terminal block, the contact plate holds the wire in place and provides an electrical connection to the PCB. The contact between the wire and the PCB is ensured by the conductive pins inserting the wire into the board.

Wire to Board Terminal Blocks provide a reliable and secure electrical connection, making them an ideal connection solution for many applications. They are commonly used in a wide range of industries, including automotive, medical and aerospace, and have become increasingly popular due to their low cost and ease of installation.

In conclusion, Wire to Board Terminal Blocks are a reliable, cost-effective and secure connection solution for many electrical applications. Their conductive pins ensure reliable electrical contact between the wires and the PCB, while their low profile design makes them ideal for high density applications. By providing a reliable connection, they have become an essential component in many industries, from automotive to aerospace.
