Connector of the basic structure are (1) contact element; (2) the insulator, (3) shell (as the varieties and decide); (4) accessories.
1. Contact element (contacts) is connector finish electric connection function of core parts. Generally by positive contact element and negative contact element composition of contact, through Yin and Yang contact element put together complete electric connection.
Positive contact element for rigid parts, its shape for cylindrical (round pin), square column shape (party pin) or flat shape (insert). Positive contact element is composed of brass and phosphor bronze.
Negative contact element that jack, is to contact the key parts, it depend on elastic structure and pin plug timeliness happen elastic deformation and produce elastic force and positive contact element form close contact, complete connection. Jack structure is a lot of more phyletic, cylinder type (split groove, throat), tuning fork type, cantilever beam type (longitudinal grooving), folding type (longitudinal grooving, 9 font), box (party jack) and hyperboloid line spring jack, etc.
2. Insulator insulator is also often called base (base) or plate (insert), its role is to make contact element according to need position and spacing arrangement, and ensure that contact element, and between contact element and shell insulation between the performance. Good insulation resistance, resistance to voltage performance and easy workability is choice insulation material processed into the basic requirements of insulator.
3. Shell is also called the shell (shell), is the connector cover, it is built-in insulation plate and pin provide mechanical protection, and provide plug and socket inserted seasonable alignment, and then will connector fixed to the equipment.
4. Attached points structure attachment and installation accessories. Structure accessories such as retainer ring, positioning key, positioning pin, guide pin, connecting ring, cable clamp, seal, seal, etc. Installation accessories such as screw, nut, screw, spring coil, etc. Attachment mostly have standard parts and interchangeable parts.
