Background technology

At present, when circuit overhauls in people's decorating house mounting circuit, light fixture, building site installation electrical equipment, office or enterprises and institutions, often need wiring, and present mode of connection is: peel off and need connect the insulated hull that two wire leading portions are about about 10cm, then doubling is joined and is wound in, then is wound around joint with insulating tape, with insulation, which increase the cross section of electric wire, add the resistance of joint, shorten the useful life of joint electric wire.A joint will waste the electric wire of about 10cm, and frequent circuit is out of order, also often in joint.

Summary of the invention

For above-mentioned prior art Problems existing, the utility model object is to provide the butt joint of a kind of power line single line, and wiring specification, do not damage the end of a thread, line does not contact with line, and insulation effect is good, simple to operate, easy to use.The technical solution of the utility model is: the butt joint of a kind of power line single line, comprises left copper pipe and right copper pipe, and described left copper pipe comprises left gum cover, cranse and elastic cap, and described right copper pipe comprises right gum cover.Right section of described left copper pipe is set to cross cut, outer silk after the internal thread of elastic cap and left copper pipe right section of cross cut close matches, the cranse that an external diameter is greater than the rear end band 0.3cm cut of elastic cap internal diameter is set in elastic cap right-hand member, the right peristoma of left gum cover is connected with the inner ring of the left peristoma of elastic cap, left gum cover left peristoma internal diameter is less than the left peristoma internal diameter of left copper pipe, the inwall of left gum cover and the outer wall of left copper pipe are fitted, and elastic cap is screwed on the outer silk of right section of left copper pipe.The internal diameter of described right copper pipe is consistent with the internal diameter of left copper pipe, left section of right copper pipe is set to cross cut, inwall and the right copper pipe outer wall of right gum cover are fitted, according to the different size of power line, the internal diameter of right copper pipe and left copper pipe is set to different corresponding models, right gum cover is enclosed within right copper pipe, and right gum cover right peristoma internal diameter is less than the right peristoma internal diameter of right copper pipe.The beneficial effects of the utility model are: this power line single line butt joint wiring specification, do not damage the end of a thread, insulation effect is good, simple to operate, easy to use.

Accompanying drawing explanation

Fig. 1 is the structural representation of a kind of power line single line of the utility model butt joint.In figure: 1 is left copper pipe; 2 is left gum cover; 3 is cranse; 4 is elastic cap; 5 is right copper pipe; 6 is right gum cover.

Embodiment

As shown in Figure 1, the butt joint of a kind of power line single line, comprises left copper pipe 1 and right copper pipe 5, and described left copper pipe 1 comprises left gum cover 2, cranse 3 and elastic cap 4, and described right copper pipe 5 comprises right gum cover 6; Right section of described left copper pipe 1 is set to cross cut, outer silk after the internal thread of elastic cap 4 and left copper pipe 1 right section of cross cut close matches, the cranse 3 that an external diameter is greater than the rear end band 0.3cm cut of elastic cap 4 internal diameter is set in elastic cap 4 right-hand member that the plastics that outer surface is laterally evenly provided with anti-slop serrations are made, the right peristoma of left gum cover 2 is connected with the inner ring of the left peristoma of elastic cap 4, left gum cover 2 left peristoma internal diameter is less than the left peristoma internal diameter of left copper pipe 1, the inwall of left gum cover 2 and the outer wall of left copper pipe 1 are fitted, and elastic cap 4 is screwed on the outer silk of right section of left copper pipe 1; The internal diameter of described right copper pipe 5 is consistent with the internal diameter of left copper pipe 1, left section of right copper pipe 5 is set to cross cut, inwall and right copper pipe 5 outer wall of right gum cover 6 are fitted, according to the different size of power line, the internal diameter of right copper pipe 5 and left copper pipe 1 is set to different corresponding models, right gum cover 6 is enclosed within right copper pipe 5, and right gum cover 6 right peristoma internal diameter is less than the right peristoma internal diameter of right copper pipe 5; During use, the end of a power line is inserted from left to right in left copper pipe 1, one end of another root power line is inserted in right copper pipe 5 from right to left, then elastic cap 4 clockwise direction is screwed onto the left end of right copper pipe 5, left gum cover 2 and cranse 3 move to right thereupon, left gum cover 2 is by left copper pipe 1 insulated enclosure, cranse 3 is by the power line banding in left copper pipe 1 and right copper pipe 5, manually move to left right gum cover 6 again, by right copper pipe 5 insulated enclosure, and this power line single line butt joint wiring specification, do not damage the end of a thread, insulation effect is good, simple to operate, easy to use.
