1, the basic structure of the connector

The basic structural parts of the connector are ① contact parts; ② insulator; ③ shell (depending on the variety); ④ accessories.

The contact is the core part of the connector that performs the electrical connection function. Generally by the positive contact and the negative contact with the composition of the contact, through the yin and yang contact to complete the electrical connection.

The positive contact is a rigid part, its shape is cylindrical (round pin), square cylindrical (square pin) or flat (insert). Positive contacts are generally made of brass, phosphor bronze.

The negative contact, the jack, is the key part of the contact pair, which is resiliently deformed by the elastic structure in contact with the pin to create a resilient force in close contact with the positive contact to complete the connection. (Vertical slot), folding type (longitudinal slot, 9-shaped), box-shaped (square jack), the shape of the jack, As well as hyperboloid thread spring jack and so on.

2. The insulator insulator is also often referred to as a base or mounting plate, and its function is to position the contacts in the desired position and spacing and to ensure the insulation between the contacts and between the contacts and the housing. Good insulation resistance, withstand voltage performance and ease of processing is the choice of insulation materials into the insulator of the basic requirements.

3. The housing, also known as the housing, is the housing of the connector, which provides mechanical protection for the built-in insulation mounting plate and pins and provides alignment of the plug and receptacle when the connector is secured to the device.

4. Accessories Accessories Attachments and installation accessories. Structural accessories such as the collar, positioning keys, positioning pins, guide pins, connecting rings, cable clamps, seals, gaskets and so on. Installation accessories such as screws, nuts, screws, coils and so on. Accessories are mostly standard parts and common parts.
