Terminal blocks, also known as wiring terminals, are an important and widely used component in electrical engineering and control engineering. In the process of electrical wiring, terminal blocks are used to ensure the conductivity connection between different parts of the conductors and the circuit. As the linking point between different parts of the wiring, terminal blocks are an indispensable part of modern technical automation. The general purpose of terminal connections is to provide a common point to connect wiring and equipment for the testing, maintenance, repair and replacement of equipment and systems. These links ensure a reliable electrical connection in order to keep current flowing evenly through the system.

31041121 terminal blocks are divided into three main categories: headers, plugs, and sockets. This series of terminal blocks have a standard modular size of 4.2mm and a spacing between adjacent poles is 2.5mm, making them compatible with a variety of applications. The connections of the 31041121 terminal blocks are very simple and need no tool. Commonly used in the control circuit, they work with flexible ribbon cables.

Header Terminal Blocks

Headers are the most basic type of terminal blocks, and they are connected from one side only. With two pins connected externally and internally, headers are mostly screwed and fixed directly onto the PCB board, allowing users to wire signals easily. Additionally, one of the two pins is a soldered, insulating material on the upper part, which acts to protect the PCB board and thus improves the safety of the device.

Plug Terminal Blocks

Unlike headers, plug terminal blocks are circuits that are connected from both sides. They are usually equipped with a removable plug, which allows users to plug wires into the terminal block. Moreover, the removable plug acts as a multifunctional block, by allowing access to the circuit and also serving as an anti-dust cover. The connections of plug terminal blocks can be made separately from the PCB board, allowing for easy connection and disconnection of the circuit.

Socket Terminal Blocks

The socket terminal blocks are also two-sided link connection circuits with a removable socket. The removable socket is another protective anti-dust cover for the terminal block. They work with plug terminal blocks and are used to connect the cables. Socket terminal blocks are usually combined with plug terminal blocks, which make it easier to detect and maintain the circuits. Furthermore, the two terminal block types allow for a quick connection and disconnection of the circuit.

Working Principle

The working principle is based on the principle of electrical contact. When the male plug is inserted into the socket, it will cause the contact between the two pins and the surface of the socket’s chamber to become conductive, forming an electrical connection. At the same time, the two pins will be clamped together, keeping a tight and and stable connection. The tight connection allows current to be transmitted continuously throughout the circuit.

In conclusion, the 31041121 terminal blocks are of great importance in electrical connection. With the three different types of terminal blocks, headers, plugs, and sockets, they are adaptable in many applications. Their unique design of two-pin connection allows signals to travel within the circuit quickly and reliably. Furthermore, the connections are hassle-free, allowing circuits to be easily connected and disconnected.
