   The basic structure of the connector consists of contacts, insulators, housings (depending on the breed) and accessories.
   The contact (contacts) is the core part of the connector to complete the electrical connection function. The contact parts are made of positive contact and negative contact, and the electrical connection is completed by insertion of the negative and positive contacts.
   The positive contact parts are rigid parts, which are cylindrical (round pin), rectangular columnar(square pin) or flat (insert). Positive contact parts are usually made of brass and phosphor bronze.
Negative contact:  it depends on the elastic structure with pin inserted and combined elastic deformation and elastic force and positive contacts formed in close contact, complete the connection. Many kinds of structure of jack, and a cylindrical (split groove, necking), fork type, cantilever type (longitudinal slot), folding type (longitudinal slot, figure 9), box shaped (square jack) and hyperboloid wire spring jack.
    The insulator is often referred to as the base (base) or mounting plate (insert), its role is to make contact by location and spacing are needed, and to ensure the insulation between the contacts between and contact with shell. Good insulation resistance, voltage resistance and workability are the basic requirements for insulating materials to be processed into insulators.
    The shell shell (shell), is also known as the connector housing, insulated mounting plate and pin provides mechanical protection it is installed, and plug and socket alignment are inserted and combined, and the connector is fixed to the equipment.
    Accessories, attachments, structural attachments and mounting attachments. Structural accessories such as clamping ring, positioning key, positioning pin, guide pin, connecting ring, cable clamp, sealing ring, gasket and so on. Install accessories such as screws, nuts, screws, springs, etc.. Most accessories have standard parts and general parts.
   The above is a connector composition introduction. Using connectors can be more flexible in designing and integrating new products, and when using components to make systems.http://www.chinacctvproducts.com/
