Power wiring pipe

Abstract

The invention provides a power wiring pipe, which adopts split connection. The power wiring pipe comprises movably-connected fixing pipes for fixing a line and a connection pipe connecting the two fixing pipes, wherein the connection pipe and the fixing pipes are in threaded connection; one end of the fixing pipe has a conical structure, the inner wall of the conical structure is provided with a clamping tongue, and the other end is provided with multiple fixing devices; a round cover plate and the fixing pipe are in movable connection; the inner diameter of an annular cover is consistent withthe maximum inner diameter of the fixing pipe, and the inner wall is provided with a rubber dustproof plate. The power wiring pipe has the advantages of light weight, simple structure, good sealing performance and the like.

Description

technical field [0001] The invention relates to the technical field of electric equipment maintenance, in particular to an electric connection tube. Background technique [0002] In the prior art, crimping or winding connection is often used for connection between wires. For crimping connection, when the wire bears a large tensile force, it is necessary to increase the crimping length to prevent falling off during use; for winding connection, the joint process is rough and the reliability is poor. Therefore, special-purpose power junction tubes appear in the market, and the structure of the power junction tubes in the prior art is relatively simple, usually adopting metal connectors to simply fix the two connection heads respectively and then connect them; the fixing method usually adopts Simple bolt tightening secures. This kind of fixing method has poor fixing effect, and the long-term use of bolts is easy to damage the rubber insulation layer coated on the surface of th...

AI Technical Summary

Problems solved by technology

This kind of fixing method has poor fixing effect, and the long-term use of bolts is easy to damage the rubber insulation layer coated on the surface of the wire, causing leakage and posing a threat to the personal safety of maintenance personnel; secondly, this type of wiring tube is usually open design, it is impossible to prevent dust and moisture in the air from entering the bare connected wires. Without the protection of the insulating coating layer, the bare wires are prone to damage and seriously affect the service life; finally, the wiring tubes in the prior art usually use Made of metal materials, it is heavy, difficult to produce, and has high production costs. It is also rusted due to the characteristics of the metal during use, and its life is limited.
