Twin-cone pushing type middle quick energy-saving conducting contact

Abstract

The invention relates to a double-cone extruded middle fast energy-saving conductive joint, which includes a middle conductive head with a conductive wire locking device at both ends. The nut is provided with a sleeve hole, and one end of the sleeve hole is provided with an internal thread to connect with the middle conductive head; a threading hole is provided in the inner threading sleeve, and an elastic slot is arranged on the surface of the threading hole in the axial direction, and the opening of the elastic slot is located in the inner threading The rear end of the tightening sleeve, the outer wall of the rear end of the inner threading sleeve is provided with a first cone surface and the second cone surface; the outer lock nut is sleeved outside the inner threading sleeve, and the inner wall of the sleeve hole corresponds to the first cone surface. The front extrusion cone surface; the end surface of the external thread end is provided with a concave cavity, and the opening of the concave cavity is provided with a rear extrusion cone surface corresponding to the second cone surface. In the present invention, when the outer lock nut is tightened, the front and rear conical surfaces are squeezed at the same time to realize double-effect rapid extrusion. Therefore, the outer lock nut can narrow the threading hole in a very short stroke, so that the internal The wire is clamped.

Description

technical field [0001] The invention relates to an intermediate conductive joint for electric conductive connection, in particular to a double-cone extrusion type intermediate fast energy-saving conductive joint.

AI Technical Summary

Problems solved by technology

However, the structure is complicated to install, it is difficult to disassemble the wire after connection, and the wire cannot be put into use again after disassembly (if the terminal conductive lug is used again, it is easy to break)

In addition, because the high-voltage cables are generally bare wires, the length of the hydraulic pliers is relatively long. If the wires are connected under live conditions, the hydraulic pliers are likely to touch other phase wires and cause short-circuit accidents. Therefore, it is not conducive to live work

However, the emergency repair of the power system generally requires live work, otherwise it will have a huge impact on people's lives and industrial production

Therefore, the current intermediate conductive joint is obviously not suitable for use
