The object of the present invention is achieved like this: a kind of high current connector, comprise socket, plug, be characterized in that plug is made up of pin insulator and at least one A contact terminal, pin insulator is the flattened rectangular body that is provided with several slots, the A contact terminal is to be fastened on the A contact chip that two shapes are identical on the pin insulator, and the A contact chip is embedded on the slot in twos relatively mutually; Socket is made up of socket insulator and at least one B contact terminal, the socket insulator is the flattened rectangular body that is provided with several plug sockets, the plug socket both sides are provided with spring leaf, the B contact terminal is to be fastened on the B contact chip that two shapes are identical on the socket insulator, the B contact chip is embedded on the plug socket in twos relatively mutually, with the spring leaf elasticity crimping that is installed on the socket insulator; Plug and socket are pegged graft, and the A contact terminal inserts in the B contact terminal, carries out current delivery by A contact chip and the crimping of B contact chip.
Described A contact terminal is made of identical A contact chip of two shapes or two shapes are identical and a side connects A contact chip.
Described B contact chip is that an end is provided with the strip thin slice that hook, centre are provided with the bending structure.
Described A contact chip is the rectangular sheet that is provided with bending, and the one side is provided with several pins, and pin and contact chip at right angles are provided with.
Described slot and plug socket are parallel longitudinal or are set up in parallel.
The present invention compared with prior art has contact closely, and contact area is big, and contact resistance is little, and perfect heat-dissipating has been improved the circuit performance of big current delivery greatly, and simple for assembly process.
