Abstract

The utility model provides a cable connection pincers, is including keeping silent and two handles, and is articulated through the round pin axle between two handles, keeping silent, keep silent and keep silent in the right side including a semicircular left side, and a handle is connected respectively to the one end of their homonymies, and it forms a ring to keep silent during their other one end contact, the inboard counteredge of keeping silent in a left side, the right side are equipped with the resistance wire inside keeping silent, and this resistance wire passes through wire connecting plug. The beneficial effects of the utility model are that: compared with the prior art, the utility model discloses be equipped with the resistance wire in the department of keeping silent, it makes that the sheath temperature risees, the inflation to generate heat after the circular telegram, so crust and the cable conductor gap grow between physically, the crust of decorporating has more easily reduced workman's the construction degree of difficulty.

Description

A kind of cable connection pincers

Technical field

The utility model relates to cable connection field, particularly a kind of electric heating jointing clamp.

Background technology

When present cable connection, workman first cuts off the crust of cable socket with two jointing clamps, exposes cable body, more exposed line body is fixed by modes such as windings, finally with insulating materials, joint is fixed again. But if the cold weather of outdoor construction, such as winter or the northern area of China, the cable sheath of cutting off is very difficult decorporates from line body, constructional difficulties.

Utility model content

For overcoming above-mentioned deficiency, the purpose of this utility model is to provide the electric heating jointing clamp of the outdoor cold snap construction of a kind of energy.

The technical solution of the utility model is specially:

A kind of cable connection pincers, comprise jaw and two handles, hinged by bearing pin between two handles, described jaw comprises semicircular left jaw and right jaw, one end of their homonymies connects respectively a handle, and when their an other end in contact, jaw forms an annulus; The inner side counteredge of left jaw, right jaw inside is provided with resistance wire, and this resistance wire is by wire attachment plug.

A material storage room that two ends are penetrating is fixed in described right jaw outside, and one end nearer apart from handle is charging aperture, and the other end is discharging opening.

Described material storage room is tapered from charging aperture to discharging opening.

The beneficial effects of the utility model are: compared to the prior art, the utility model is provided with resistance wire at jaw place, and the rear heating of energising makes cable sheath temperature raise, expand, so the gap between crust and cable body becomes greatly, the crust of more easily decorporating, has reduced workman's difficulty of construction.

Brief description of the drawings

Fig. 1 is schematic diagram of the present utility model.

Detailed description of the invention

As Fig. 1, a kind of cable connection pincers, comprise jaw and two handles 11, hinged by bearing pin 12 between two handles 11, jaw comprises semicircular left jaw 1 and right jaw 2, and one end of their homonymies connects respectively a handle 11, and when their an other end in contact, jaw forms an annulus.

The inner side counteredge 13 of left jaw 1, right jaw 2 inside are provided with resistance wire, and this resistance wire is by wire attachment plug 21.

A material storage room 22 that two ends are penetrating is fixed in right jaw 2 outsides, and one end nearer apart from handle is charging aperture 23, and the other end is discharging opening 24.

This material storage room 22 is tapered to discharging opening 22 from charging aperture 23. Design facilitates charging like this.

Operation principle is:

While connecing cable with it, if construction temperature is lower, plug can be inserted on power supply, cable is placed in jaw, rotation jointing clamp, because resistance wire heating, the crust temperature of cable is raise, and after blade is chopped crust off, the crust of joint one side expands because temperature raises, so and gap between cable body becomes large, easily decorporate.

After outer the decorporating at two cable connection places, connect cable body according to prior art, because there is gap joint, can generates heat and bring unsafe factor. Now, put into the materials such as block tin at the charging aperture of material storage room, plug is inserted on power supply, discharging opening is downward, in the time that block tin melts, just flow out from discharging opening, Artificial Control flows in joint, both reduce the gap of contact position, reduced its resistance, reinforced again fixing between two cables.

Finally, put into the Insulating Materials such as plastics at the charging aperture of material storage room, the same, after it is softening, drop in joint, after Insulating Materials is cooling, be fixed on the outer surface of joint. Make like this fixed effect between insulating barrier and the cable body of joint be better than present adhesive tape and be directly entangled in its outside.

Other guide is shown in prior art.
