Production method of copper core cable soldered and sealed intermediate joint

Abstract

The invention relates to a production method of a copper core cable soldered and sealed intermediate joint. The production method comprises the following steps that: 1) a cable, a wire 1 and a wire 2 are skinned, and the wires are made into a fixedly-connected bare joint 3; 2) the bare joint is wound with a solder wire 4; 3) the solder wire 4 is wrapped in aluminum foil paper 5; 4) a heat gun 6 is turned on to uniformly heat the aluminum foil paper, so that the solder wire can be indirectly heated to be soldered on the bare joint; 5) the joint is sleeved with a heat shrinkable sleeve 7, and the heat shrinkable sleeve 7 is uniformly heated with the heat gun; 6) the heat shrinkable sleeve shrinks and attaches to the bare joint; 7) the production of other wire joints of the cable is completed at a place where the above wire joint is not located according the step 1 to step 6; 8) cable sheaths at two ends of the joints are wrapped in hot-melt adhesive tapes 9 by one to two laps; and 9) the hot-melt adhesive tapes are sleeved with a large heat shrinkable sleeve 10, and the large heat shrinkable sleeve is uniformly heated with the heat gun, and therefore, the large heat shrinkable sleeve can shrink, and the hot-melt adhesive tapes in the large heat shrinkable sleeve can be melt, and the heat shrinkable sleeve can be bonded with the cable sheaths by the hot-melt adhesive, so that sealing and waterproof performance can be realized.

Description

1. Technical field [0001] The invention relates to a copper core cable soldering and sealing intermediate joint manufacturing method; it belongs to the construction technology field of low-voltage power distribution system and weak current information exchange system wiring. 2. Background technology [0002] At present, low-voltage power distribution systems and weak current information exchange systems inevitably require soldering and sealing waterproof intermediate joints when wiring cables or wires. There are several soldering and sealing waterproof processes for joints, and common better joints The method is: 1. After dipping tin in the electric tin furnace or soldering with an electric soldering iron, use high-pressure self-adhesive tape for waterproof treatment, and then protect it with electrical insulating tape; 2. Use special heat-shrinkable waterproof joints for insulation and protection after soldering; 3. , Special butt joint waterproof joint, the cable conduct...

AI Technical Summary

Problems solved by technology

[0006]1) During copper core cable soldering and sealing and waterproof intermediate joint wiring operations, it is often limited by power supply and working environment, so it is difficult to solve the difficulties in the construction of copper core cable joints. Solve the problem that the power supply and wind force are too large and the temperature is too low to work; solve the problem that the wire and solder are oxidized due to heating during the soldering process, the tin liquid is lost after the solder is melted, the soldering quality is difficult to guarantee, and the problem of large loss of soldering materials
