Conductive connecting device

The invention provides a conductive connecting device. The conductive connecting device comprises a first conductive part, a second conducive part and a compressing device. The first conductive part comprises a connecting head, wherein the connecting head comprises a plurality of contact chips which are arranged in the circumferential direction of the connecting head, and the multiple contact chips form an accommodating hole in an enclosing mode. The second conducive part is detachably connected with the first conducive part, and the contact chips are connected with the second conductive part in an abutting mode. The compressing device comprises a tip cone, wherein the tip cone is matched with the accommodating hole and enables the multiple contact chips to be in close contact with the second conductive part. By applying the technical scheme of the conductive connecting device, the tightness of the connection between the contact chips of the first conducive part and the second conductive part is improved.
