As the name suggests, electronic connectors are all about connecting circuits together. In practical applications, the four basic structures of the product are indispensable, namely insulators, accessories, contacts and shells. Next, we will introduce these mechanical components one by one. I hope that after reading the article, you will have a good understanding of these components. Products have more awareness.


1. Insulator

The insulator part of the electronic connector is also called the base or the mounting plate. Its purpose is to allow the contacts to be arranged according to the required spacing and position to ensure good insulation between each contact and the shell. ,

For electronic connectors, it is very important to have good insulation resistance and strong withstand voltage performance, so the insulation material should be selected when this part is constructed and produced.

2. Contacts

The contact piece is one of the core mechanisms of the electronic connector. It consists of a male contact piece and a female contact piece to form a contact pair. Through the insertion of the two, the effect of electrical connection can be achieved.

Usually, the positive contact part is a rigid part, it is mainly made of brass and phosphor bronze, and the shape can be divided into cylindrical, square cylindrical and flat.

As for the female contact, it needs to rely on the elastic structure to deform when it is inserted, and realize the connection after contact with the male contact. It has many shapes, such as folded type, cylindrical type, cantilever beam type, etc.

3. Shell

It is also the housing part of the electronic connector. Its main function is to protect the built-in insulating mounting plate and pins, and at the same time, it can provide alignment during insertion and allow the electronic connector to be connected to the device.

4. Accessories

The accessories of the electronic connector include two parts: installation accessories and structural accessories. The installation accessories mainly include nuts, screws, screws, spring rings, etc., and the structural accessories include positioning pins, sealing rings, clip rings, cable clamps, etc.
