Terminal blocks, also known as terminal strips, provide secure connections in electrical systems, used for transmission, distribution, and storage of power. Terminal blocks are often sophisticated pieces of industrial equipment, designed to provide a safe, reliable interface between the electric system and a variety of other external circuits and devices. Generally, they are used to connect and consolidate multiple signal and power lines into a single connection at a single location. Terminal blocks typically come in two basic varieties, panel mount and plug-in. This article focuses on panel mount terminal blocks.

3056996 Application Field and Working Principle

Panel mount terminal blocks are often versatile and used in a variety of applications. They offer a dependable way to join a variety of different wire gauges, from large multi-conductor feeders to small single-conductor leads. They can also be used in high-voltage applications, such as power distribution panels, DC motor-control panels, and main-command centers. Other common applications include control and lighting panels, securing and protecting electronic components, and providing efficient shunt networks.

The typical design of a panel mount terminal block includes a base and contact clamp. The base usually consists of a mounting plate attached to the enclosure or individual wires. This part houses the contact clamps, which are typically made of high-conductive and non-corrosive materials, such as copper or brass. It also includes insulation and isolation portions that helps protect the contacts and wires from accidental contact.

The contact clamps are designed to securely clamp the inserted leads. This is usually achieved through a spring receiving mechanism, which exerts a compressive force onto the lead to hold it in place. Several types of insulators are usually used to ensure electrical continuity between the parts. The contact clamps also contain locking mechanisms that prevent the lead from being accidentally removed.

In order to operate a panel mount terminal block, the leads are first inserted through the base portion of the block. Then, the contact clamps are tightened, ensuring that all of the wires and contacts are held securely. The leads can then be connected to other components, enabling a safe and reliable link between the two circuits. In most cases, the panel mount terminal block is then wired through the internal wiring of the device, or connected to an external power source.

Panel mount terminal blocks are commonly used in a variety of industries, including industrial, military, aerospace, automotive, and medical. They are available in a wide range of sizes and materials, and are designed to meet industry standards for safety and reliability. As such, these components are often used to provide dependable connections for critical electrical systems in high-voltage applications.
