What is the connector made?

The contact (contacts) is the core part of the connector to complete the electrical connection function. Generally, a contact pair is composed of a male contact and a female contact, and the electrical connection is completed by inserting the female and male contacts.

The male contact is a rigid part, and its shape is cylindrical (round pin), square pillar (square pin) or flat (blade). The male contact is generally made of brass or phosphor bronze.

The female contact is the socket, which is the key part of the contact pair. It relies on the elastic structure to deform elastically when it is inserted with the pin to generate elastic force to form close contact with the male contact to complete the connection. There are many types of jacks, including cylindrical (split slot, necking), tuning fork, cantilever beam (longitudinal slotting), folding (longitudinal slotting, 9-shaped), box (square jack) and hyperboloid wire spring jacks.

2. Insulator Insulator is also often called base (base) or mounting plate (insert), its function is to arrange the contacts according to the required position and spacing, and to ensure the insulation between the contacts and between the contacts and the housing performance. Good insulation resistance, voltage resistance and easy processing are the basic requirements for selecting insulating materials to be processed into insulators.

3. The shell, also known as the shell (shell), is the outer cover of the connector. It provides mechanical protection for the built-in insulated mounting plate and pins, and provides alignment between the plug and the socket, thereby fixing the connector to the device.

4. Accessories are divided into structural accessories and installation accessories. Structural accessories such as circlip, positioning key, positioning pin, guide pin, coupling ring, cable clamp, sealing ring, sealing gasket, etc. Install accessories such as screws, nuts, screws, spring rings, etc. Most of the accessories have standard parts and common parts.
