The four basic structural components of automobile connectors are as follows:
First, contact, is the automotive connector to complete the electrical connection function of the core parts. Generally, a contact pair is composed of a positive contact part and a negative contact part, and electrical connections are completed by inserting and closing the Yin and Yang contact parts.
The positive contact is a rigid part with a cylindrical shape (round pin), a square column shape (square pin) or a flat shape (pin). Positive contact parts are generally made of brass and phosphor bronze. The negative contact part, namely the jack, is the key part of the contact pair. It depends on the elastic structure when it is inserted with the pin, elastic deformation occurs and the elastic force is generated to form close contact with the positive contact part to complete the connection. There are many kinds of jack structure, cylinder type (split groove, telescopic mouth), tuning fork type, cantilever beam type (longitudinal groove), folding type (longitudinal groove, figure 9), box shape (square jack) and hyperboloid spring jack.
Second, the shell, also known as the shell (shell), is the outer cover of the automobile connector, which provides mechanical protection for the built-in insulation mounting plate and pin, and provides the alignment of the plug and socket when plugged in, and then the connector is fixed to the device.
Three, insulator, insulator is also often called the automobile connector base (base) or installation plate (insert), its role is to make the contact parts according to the required position and spacing, and ensure the insulation performance between the contact parts and the contact parts and the shell. Good insulation resistance, voltage resistance and easy processing are the basic requirements for selecting insulating materials to be processed into insulators.
Four, accessories, accessories are divided into structure accessories and installation accessories. Structural accessories such as clamping ring, positioning key, positioning pin, guide pin, connecting ring, cable clamp, sealing ring, gasket, etc. Mounting accessories such as screws, nuts, screws, springs, etc. Most of the accessories are standard parts and general parts.
