Classification of connectors by terminal harness processing factory
Time:2024-01-03 Read: 825

The terminal harness is composed of electronic connecting wire terminal and connector. The main products purchased in the terminal harness processing factory can be divided into three categories: wires, terminals and connectors. Among them, connector structures are increasingly diversified, and new structures and fields are emerging.Terminal harness processingHow does the factory classify connector types?


1、 According to the function of internal and external connection of electronic equipment, the interconnection can be divided into five levels.


1. Internal connection of chip package.


2. The connection between the IC package pin and the PCB, such as the printed circuit connector.


3. The connection between a printed circuit and a conductor or printed circuit board is a board-to-wire connector.


4. The board-to-board connection is the board-end connector.


5. The connection between equipment and equipment, that is, line-to-line connector.

2、 The basic performance of terminal harness processing factory for connectors can be divided into three categories:


1. Mechanical performance: The insertion and extraction force is mainly divided into insertion force and extraction force, and the requirements of the two are different. From the perspective of use, the insertion force is effective, but if the pull-out force is too small, it will affect the reliability of contact. The insertion and pull-out force and mechanical life of the connector are related to the coating quality of the structural contact part of the contact and the arrangement dimension accuracy of the contact.


2. Electrical performance: including contact resistance, insulation resistance and electrical strength.

① The contact resistance of the connector ranges from a few milliohms to tens of milliohms.

② The number of insulation resistance varies from hundreds of megohms to thousands of megohms.

③ Dielectric strength is the ability to withstand the rated test voltage between connector contacts or between the contacts and the shell.


3. Environmental performance: including temperature resistance, humidity resistance, salt fog resistance, vibration resistance, impact resistance, etc.
