A conductive swivel joint is provided to reduce the number of components by assembling an upper joint to a lower joint rotatably, integrating a wire with a conductive portion, and causing a contact bus and the conductive portion to slide mutually. A conductive swivel joint comprises an upper joint(10), a lower joint(20), and a wire(30). The upper joint includes a clamping part(11a) for a first member(1) at the outside, and a contact bus(31). The inside of the upper joint is hollow. The contact bus passes through the upper joint, and places its end in the hollow inside to the upper joint. The lower joint includes a clamping part(21) for a second member(2), and a contact part(22). The lower member is penetrated axially. The contact part has a conductive portion(22a) at the top, which is in contact with the contact bus. The lower joint rotates in the upper joint. With regard to the wire inserted to the hole of the lower joint, the top part of the wire is connected with the contact part electrically, and the lower part of the wire is exposed out of the bottom part of the lower joint. The swivel joint rotate the first member and the second member relatively. |
