Terminal blocks, sometimes referred to as terminal boards or plugs, are a type of electrical connection device designed to connect two or more electrical conductors. The terminal block product range is incredibly wide and from simple plug-in terminal blocks to the most complex spring-loaded terminal blocks, this highly-specialised electrical connection device is designed to ensure that two or more electrical conductors are safely and securely held together.

Terminal blocks are typically used in many applications, ranging from the widely-used industrial and control panel applications to electrical test and measurement equipment.

OSTKH201551 Terminal Block is an example of a Wire-to-Board terminal block, providing an effective and reliable wired connection between an existing wire-to-board connection and a power or load terminal. This terminal block is designed with a four-pin terminal construction for resilient electrical connection with wire-to-board connectors. It features two-stage clips for secure wire insertion and protection against contact loosening. The terminal block gets its name from the two-holes in each of the four pins which allow it to be securely connected to a board using two screws for reliable wire-to-board termination.

OSTKH201551 is ideally suited for use in a range of wire-to-board applications, where it provides a reliable connection between the board and the connector.

Working Principle

The terminal block works by creating a secure connection between two electrical conductors. This is achieved by using two-stage clips which allow wire to be securely inserted into one end of the block and a metal contact to be inserted into the other. The metal contact then gets securely held in place by the clips; these clips are designed to keep the wire securely fastened and ensure that the connection remains secure.

Once the connection is made, the terminal block can be used to provide an electrical connection between the wires and the power source or load terminal. This means that a single terminal block can be used to provide power to multiple devices without having to use multiple wires.

The terminal block can also be used to provide protection for the wires. This is achieved by preventing contact loosening due to the two-stage clips that hold the wires securely. Furthermore, the terminal block can also provide additional protection against electrical shock or short circuit due to the two-holes which are designed to provide a secure connection between the terminal block and the board.

The OSTKH201551 terminal block is a highly reliable and cost-effective solution for use in a range of wire-to-board applications. It is designed to provide a secure connection between an existing wire-to-board connection and a power or load terminal, and is ideal for use in a range of different electrical applications. The terminal block has two-stage clips for secure wire insertion, which prevent contact loosening and provide additional protection against electrical shock or short circuit.
