The object of the present invention is achieved like this: a kind of current connector, comprise plug that is provided with the A contact terminal and the socket that is provided with the B contact terminal, be characterized in the identical A contact chip of two shapes that the A contact terminal connects for " U " shape, 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, and the A contact terminal is fastened on the slot; 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 that an end is provided with the vertical bar shape thin slice that hook, centre are provided with convex shoulder, and the B contact chip is embedded on the plug socket and the spring leaf elasticity crimping that is installed on the socket insulator in twos relatively mutually; 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 chip is the rectangular sheet that is provided with bending, dogging shoulder, and rectangular sheet 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.
