Terminal blocks are electrical connections that are easily made and are also easily unmade. They provide a reliable way of connecting wires and allowing current to flow between them. A wire-to-board terminal block is particularly useful when connecting signals or power from a printed circuit board (PCB) to an electrical device, making for a secure and reliable connection. The 1990753 application field and working principle will be discussed in more detail below.

The Application Field

The 1990753 terminal block is a single-level, twisted-pair, wire-to-board connector. It was primarily designed for use in industrial electronics, medical control systems, telecommunications, patient monitoring, automotive, and audio/video applications. With its 8mm pitch and 4.2mm width, it is compact and lightweight, making it ideal for such applications.

The connector has a 2-way polarisation system to ensure the wires are correctly connected every time. It features a positive lock clamp design that ensures a tight connection between the terminal and the wire, ensuring it won\'t become loose over time. The connector also has a shrouded contact to protect against potential shorts and accidental contact with the wiring.

The Working Principle

The 1990753 terminal block uses a spring-clamp design to make the connection. The insulation displacement contact (IDC) makes for quick installation without the need for wire stripping or soldering. It works by using a sharp blade to puncture the wire insulation and clamp down on the wire, trapping it between two metal elements.

The insulation is pushed back, and the wire is trapped between two metal elements. This makes for a robust and reliable connection, ensuring it won\'t become disconnected over time. It also provides an optimal level of insulation between the wires and ensures that any induced noise is minimised.

The connector also features a double-locking system for added safety. This means that once the terminal block is connected, it won\'t accidentally disconnect in the event of vibrations or other disturbances.

Conclusion

Terminal blocks like the 1990753 are an effective solution for wire-to-board connections in industrial electronics, medical control systems, and other applications. It has a 2-way polarisation system, a positive lock clamp design, and a shrouded contact to provide a secure and reliable connection every time.

The connector uses an insulation displacement contact (IDC) that makes for quick installation without the need for wire stripping or soldering. Additionally, the connector features a double-locking system for added safety. When used correctly, the 1990753 terminal block can ensure that your wiring is reliable and secure.
