The basic structure of the connector
The basic structural parts of the connector have 1 contact piece; 2 insulator; 3 outer casing (depending on the type); 4 accessories.
1. Contacts are the core parts of the connector that perform electrical connections. The contact pair is generally composed of a male contact and a female contact, and the electrical connection is completed by the insertion of the female and male contacts.
The male contact is a rigid part that is cylindrical (round pin), square (square pin) or flat (tab). Positive contacts are typically made of brass or phosphor bronze.
The female contact, that is, the jack, is a key component of the contact pair. It relies on the elastic structure to elastically deform when it is inserted into the pin, and generates elastic force to form close contact with the male contact member to complete the connection. There are many types of jacks, such as cylindrical (grooving, shrinking), tuning fork type, cantilever beam type (longitudinal slotting), folding type (longitudinal slotting, 9-shaped), box shape (square socket) And a double-curved wire spring jack.
2. Insulator insulators, also commonly referred to as bases or inserts, serve to position the contacts in the desired position and spacing and to ensure insulation between the contacts and between the contacts and the outer casing. . Good insulation resistance, voltage resistance and ease of processing are the basic requirements for the selection of insulating materials into insulators.
3. The housing, also known as the shell, is the connector's outer cover that provides mechanical protection for the built-in insulated mounting plate and pins and provides alignment when the plug and socket are mated, thereby securing the connector to the device.
4. Accessories Accessories are divided into structural and installation accessories. Structural accessories such as collars, positioning keys, locating pins, guide pins, coupling rings, cable clamps, seals, gaskets, etc. Install accessories such as screws, nuts, screws, coils, etc. The accessories are mostly standard and general.
