TERMINAL BLOCKS - HEADERS, PLUGS AND SOCKETS

Terminal blocks, which consist of headers, plugs and sockets, are used in electronic equipment to form a connection between an external device and the equipment’s internal wiring. They enable connections between printed circuit boards (PCBs) and other components. In addition, they also provide a means of connecting cables, components, and circuit boards from different sources. This article provides an overview of the types of terminal blocks and details on the self-locking terminal block system currently available.

Types Of Terminal Blocks

Terminal blocks can be classified into several categories based on their working principle, application field, and features. These include spring, screw, cage-clamp, push-in, and PCB terminal blocks. Each type is used for specific application and comes with a set of individual features.

Spring Terminal Blocks

Spring terminal blocks are generally used for low current applications such as appliances, lighting, and low-power equipment. They use a spring-clamp system and are available in a range of sizes and formats. They offer single-pole, double-pole, and multi-pole configurations; they are easy to assemble and are IP rated for dust and water resistance.

Screw Terminal Blocks

Screw terminal blocks are commonly used for medium- to high-power applications. They use a two-part screw clamp system that consists of a screw and a terminal block with a metal busbar. They are usually used in industrial control systems and offer a higher level of protection from dust and water. They also provide increased mechanical stability over spring terminal blocks.

Cage-Clamp Terminal Blocks

Cage-clamp terminal blocks use a two-part system with a patented cage clamp technology that is designed to clamp the conductor securely. This technology ensures an optimal electrical connection and provides higher current carrying capacity than spring terminals. These terminal blocks are suitable for higher power applications and complicated wiring schemes.

Push-In Terminal Blocks

Push-in terminal blocks offer a convenient, tool-free connection technology. These terminal blocks are designed for fast and easy installation in a wide range of industrial and commercial electrical applications. They provide a secure connection and higher current carrying capacity than traditional screw-type terminal blocks.

PCB Terminal Blocks

PCB terminal blocks are designed for use in printed circuit boards (PCBs). These terminal blocks are manufactured with either through-hole or surface-mount technology, making them suitable for use in a variety of applications. They are also available in various sizes and formats, offering flexibility and compatibility with different PCBs.

Self-Locking Terminal Blocks

New developments in terminal block technology have led to the introduction of self-locking terminal blocks. These terminal blocks are designed to provide reliable connections in even the harshest of environments. They provide an easy and secure connection by using a sacrificial ear design that requires no extra locking mechanisms or components. The design also reduces the risk of accidental disconnection.

The self-locking terminal blocks are available in a variety of sizes, formats, and terminal types to meet the needs of a wide range of applications. They are designed for high current applications such as solar power, automotive electronics, industrial power, and machine control.

In conclusion, terminal blocks are a reliable and cost-effective solution for a variety of applications. They are available in a variety of styles and configurations for different applications. In addition, the self-locking terminal block system provides a secure connection that ensures reliable, long-term performance.
