Terminal blocks-headers, plugs and sockets are essential components of all electronic equipment, ranging from household appliances to sophisticated medical monitoring systems. Terminal blocks provide the service of connecting an electrical circuit to other terminals and are used to provide a safe and reliable connection to low current and low voltage, sometimes signal level, connections. They also provide accurate temperature readings for system accuracy and safety and are available in a variety of sizes, designs and configurations.

Overview

Terminal blocks usually consist of a body, often made from thermoplastic or metal, with a flat base or a retaining surface which is used to secure the contacts. This material offers both mechanical and electrical properties which keep the system working correctly. The contacts are usually made of spring-steel or copper allowing electrical current to flow through. They are usually crimped or soldered to the body or a removable holder as part of the assembly process.

The terminal blocks are divided into two main types; headers and sockets. Headers incorporate a limitation component, a lever or actuator, which keeps the terminals in place and allows a firm connection of the wires while retaining the flexibility of holding the wires in place or allowing easy replacement of the wires. Headers have been designed to fit a wide range of applications such as the car industry, telecommunications, audiovisual equipment, medical equipment and general industry. Sockets are made for connecting external electrical circuits to the main wiring system and are considered the ideal alternative to wiring during installations, maintenance and repair operations. A socket has typically two parts – body and pin – and typically come with a mounting screw for secure connections. A socket is usually mounted into an existing device, providing a secure connection and creating a point of entry for the wiring and connections.

1809018 Application Field and Working Principle

The 1809018 terminal block-headers have been designed specifically for the car industry. They have a low profile design, allowing for the wires to be more concealed during installation and replacing the traditional bulky wiring products. The terminals are made from UL certified material which provide both mechanical and electrical properties and are pre-assembled with the required springs and actuators. The body has a fixed wing screw retention feature that provides quick installation. The 1809018 terminal blocks also have a built-in LED indicator to provide indication of wiring and connections status.

The terminal blocks-headers work on the principle of a positive contact. The contact is formed when an electrical current is applied and the contacts are tightened. The contact can be either a straight or angled type depending on the applications. Electrical currents flow through the contacts creating a safe and reliable connection. The contacts are also held firmly in place since they are pre-crimped to the body while the wingsnuts provide a secure connection.

Conclusion

In conclusion, terminal blocks-headers, plugs and sockets are essential components of all electronic equipment, and they offer a variety of advantages. The 1809018 terminal block-headers offer a low profile design, UL certified material, pre-assembling with the required springs and actuators, and LED indicators to provide indication of wiring and connections status. The terminal blocks-headers work on the principle of a positive contact and provide a safe and reliable connection through the contacts.
