What are the common knowledge points in the use of automobile connectors?

We know about the use of automobile connectors. We also need to be generally clear about its structure and familiar with common structures. Now let's talk about the common knowledge points in the use of automobile connectors?

1. Shell

Manufacturer of automobile connector plug-in: the shell is also called the shell, which is the outer cover of automobile connector. It provides mechanical protection for the built-in insulated mounting plate and pins, and provides alignment when the plug and socket are inserted, thereby securing the connector to the device.

2. Contacts

Automobile connector plug-in manufacturers believe that it is the core part of the automobile connector to complete the electrical connection function. Generally, the contact pair is composed of male and female contacts, and the electrical connection is completed through the insertion of female and male contacts. The male contact is a rigid part, and its shape is cylindrical (round pin), square cylindrical (square pin) or flat (insert). The male contact point is usually made of brass and phosphor bronze. The female contact, namely the jack, is the key part of the contact pair. It relies on the elastic deformation of the elastic structure when the pin is inserted to produce elastic force, which forms close contact with the male contact to complete the connection. There are many kinds of jacks, including cylindrical (slotted, necked), tuning fork, cantilever (longitudinally slotted), folding (longitudinally slotted, 9-shaped), box type (square jack), hyperboloid wire spring jack.

3. Insulator

Manufacturers of automobile connector plug-in believe that the insulator is usually called the base or plug-in of automobile connector. Its function is to arrange the contacts according to the required position and spacing to ensure the insulation performance between the contacts and between the contacts and the shell. Good insulation resistance, withstand voltage and processing performance are the basic requirements for the selection of insulating materials processed into insulators.
