Description

Technical Field

[0001] The invention belongs to the technical field of wiring harness connectors, and in particular, relates to a simple and easy to disassemble terminal connector and an installation method thereof. Background Art

[0002] The wiring harness connector is a positioning connector that connects electronic circuits. It consists of two parts, the plug-in and the connector. Under normal conditions, it can be completely separated. The similarity between switches and connectors is that the purpose of converting the connected circuit is achieved by changing the contact state of their contact pairs. The essential difference is that the plug-in connector only has two states: insertion and removal. The switch can realize the conversion of the circuit on its body, while the connector cannot realize the conversion on the body. There is a fixed corresponding relationship between the contact pairs of the connector. Therefore, the connector can also be called a connector. To put it simply, the difference is that the connector is the connection between wires; the connector is the connection between wires and boards. But in our lives, it often refers to the same type of product vaguely. The terminal is a part of the connector, in order to facilitate the connection of the wire. It is actually a piece of metal sealed in insulating plastic, with holes at both ends for inserting wires.

[0003] Most of the wiring harness connectors that are popular in China currently require special tools to remove the terminals. Some connectors are difficult to remove the terminals even with special tools due to their complex structures. Some professional engineers are unable to remove the terminals if they are not familiar with the connectors. In addition, if professional tools are used improperly, the connectors will be directly damaged and cannot be repaired. Summary of the invention
