Case
　　The electrical connector housing of the plug socket housing means, connected to the nut, the rear attachment. Shell is to protect the insulator and the contact body (pin jack generic term) and other internal parts of the electrical connector is not damaged. The above positioning keyway ensure plug and socket positioning. Plugs and sockets for connecting nut connection and separation. Rear accessory protects the wire and the termination of the contact body from damage and to secure the cable. Electromagnetic shielding housing also has a certain role. Housing generally use aluminum processing (machine, cold extrusion, die casting). Steel casing used for welding and high temperature glass sealing electrical connectors.
　　Insulator
　　The loading pin insulator insulator insulator mounted jack. Interface seal body, seal line body and other components. For holding pin jack at the set position, and each and all contact between the contact body between the body and the casing are electrically insulated. Seal body seal line insulator body made by adding interface seals measures to improve the environmental resistance of the electrical connector. In order to meet the high temperature, low temperature, flame retardant, to ensure stable and reliable part geometry. Insulator mostly using thermoset molding. Interface seal body, seal line body with silicone rubber molding and other forming.
　　Contact body
　　Pin jack is the contact body collectively, into welded, crimp style and fit around, etc., used to implement the circuit. Electrical connector pin jack is a key element, which directly affects the reliability of the electrical connector. Pin jack they use good conductive properties of elastic copper alloy machined from the surface using silver gilt achieve low contact resistance and corrosion protection purposes.
　　Structural features are: resistance to environmental, bayonet (fast) connection, multiple keys (anti misinsertions), contact and wire crimp connections (single take delivery easy troubleshooting). Shell plus 360 ° shielding ring ensure electromagnetic interference shielding.
