Introduction to Mechanical Properties of Wiring Terminals

1、 Insertion force of wiring terminals

When inserting a crimped terminal into a Chinese connector with difficulty, the resistance felt is the insertion force between the terminals. Terminal block is a type of accessory product used to achieve electrical connections, which is classified as a connector in industry. The UK terminal block is suitable for a large number of wire interconnections. In the power industry, there are specialized terminal blocks and terminal boxes, which are full of terminal blocks, single-layer, double-layer, current, voltage, ordinary, interruptible, and so on. A certain crimping area is used to ensure reliable contact and sufficient current flow. Terminal blocks are used for the convenience of connecting wires. They are actually a metal piece enclosed in insulating plastic, with holes at both ends for inserting wires and screws for fastening or loosening. For example, two wires sometimes need to be connected and sometimes need to be disconnected. In this case, they can be connected with terminals and can be disconnected at any time without the need to weld or wrap them together, which is very convenient and fast.

2、 Terminal retention force

The force used to fix the terminal block in its position is the retention force of the terminal block

The retention of wiring terminals determines the difficulty of pulling them out of the connector

Maintaining force of wiring terminals to prevent their failure - when the wiring terminals are loose or pulled out of the connector under pressure

Most suppliers use shrapnel to prevent terminal failure, loosening, or being pulled out of the connector under pressure.

3、 The pulling force of wires

The force required to separate the wire from the terminal block is the pulling force,

Designed and produced extrusion mechanisms for each wiring terminal to increase tension. The greater the tension, the better the compaction quality. The environment of connectors with potential sources of pressure can also affect the tension of wires.

4、 Combining ability

The binding force is defined by each branch or matching branch. Matching force is the force required to connect or match the male and female terminals to a fully matched state.

5、 Pull-out force

Pull out force is the force required to separate two wiring terminals

6、 Vertical force

Vertical force is the pressure applied vertically to the terminal block or the continuous force on the electrical contact. Vertical force is an important mechanical characteristic, as sufficient vertical force ensures that corrosive gases do not enter the connection area of the wiring terminals, thereby affecting the performance of the circuit.

7、 Durability

Durability refers to the number of times a system's wiring terminals are coordinated and separated before performance issues continue to decline. It is also a process that affects the coating material, coating thickness, usage, wear, rupture, and other functions.
