The electric connector is a common type of connector, electrical connection and signal transmission between the device and the device, component and component,system and system, constitute a complete system of basic element. Then the electric connector is composed of what parts of the user know? Today Xiaobian to describe specific electric connector structure, the hope can help to you.

The electric connector is composed of a fixed end connector (hereinafter referred tothe electric connector socket), the free end (hereinafter called plug) composition.Socket through its square (circular) disc is fixed on the electric components (individualalso adopts welding mode), general cable plug, connected by the connecting nut to realize plug, socket.

The electric connector is composed of a casing, an insulator, a contact body three basic unit.

Shell

Electrical connector housing refers to the plug in the socket shell, a connecting screw cap, tail attachment. Shell role is to protect the insulator and a contact body(commonly known as pin jack) and other internal parts from being damaged electrical connector. Positioning keyway above ensure plug and socket positioning. The connecting nut for the plug socket connection and separation. Tail attachment forprotection and contact wire body end junction from injury and is used for fixing cable.The shell is also provided with a certain electromagnetic shielding effect.

Shell using aluminum alloy processing (general machine, cold extrusion, die-casting)and. Steel casing used for glass seal and high-temperature resistant electricconnector.

Insulator

By mounting pin insulator, charging socket insulator. Interface sealing body, wire sealing body etc.. To maintain a pin socket in the set position, and make everycontact between body and the contact body and a shell body of electrical insulation.Through an insulator and interface sealing body wire sealing body made sealingmeasures to improve the environment resistance of electric connector.

In order to meet the high temperature, low temperature resistant products, flame retardant, ensure the part geometry size is stable and reliable. Insulator mostly usedthermosetting plastic molding. Interface sealing body, wire sealing body adopt silicon rubber mould shaping.

Contact body

A pin socket is a contact body general, divided into welding type, crimping and winding connection type, used to connect the circuit realization.

A pin socket is a key component of electric connector, which directly affects thereliability of electrical connector. A pin socket mostly adopts elastic copper alloymaterial for good conductivity increases from the surface using silver plated to achieve low contact resistance and anti corrosion of the. Jack are generally splitgroove type socket, wire spring jack, crown spring plughole and punching.

Structure is characterized in that the environment resistant, bayonet (fast)connections, multiple keys (anti error plug), contact body and a wire crimpingconnection (single take convenient for fault processing). Shell shielded environment license 360 degree electromagnetic interference shielding ability.
