Terminal blocks are electrical ways of connecting two or more wires together into a single unit which can be used as one large connector. Panel mounted terminal blocks (also known as board mount terminal blocks) are mounted on the surface of printed circuit boards, and are configured to require no solder. Panel mounted terminal blocks provide a stable electrical connection with the convenience of a secure mechanical connection.

The terminal block\'s unique advantages come from its small profile, efficiency in providing a secure connection, and low cost. Panel mounted terminal blocks have typical applications that can be divided into two categories: 1) low voltage/low current connections, and 2) high voltage/high current connections. Low voltage/low current applications include Industrial Controls, consumer electronics, and DC power systems. High voltage/high current applications are things like high voltage power supplies, motor controls, and circuit breakers. In both applications, panel mounted terminal blocks provide reliable, tight connections with a secondary method of securing the wires in place.

The working principle behind panel mounted terminal blocks is simple. Its main components include: a spring-loaded clamp or lever, a conductor contact(s); and a housing. The connection between the wire and terminal block is established by first sliding a conductor into the contact area, and then applying pressure from the spring-loaded clamp or lever. This pressure applies the necessary force to the conductor contact in order to both secure and electrically connect the wire. The housing is typically made of a thermal composite resin material, and it serves to enclose the electrical connection and act as a strain relief for the connected wire.

Panel mounted terminal blocks provide an effective, reliable, and economical method of manufacturing and powering electrical devices and equipment. The quick and secure connection provided by panel mounted terminal blocks eliminates the need for soldering for many applications, and can save companies time and money. The simple and affordable construction of panel mounted terminal blocks, also makes them a popular choice for companies who are looking for an efficient and inexpensive way to complete their electrical projects.
