Abstract

The utility model relates to a pair of cold pressure connecting wire crimping tongs of a cable. The utility model is mainly composed of a tong head and a supporting seat. A module is clamped in the tong head, and the tong head is sheathed and axially positioned on a guiding seat. The supporting seat is provided with a slide shaft which is penetrated through the guiding seat and is contacted with the module of the tong head. Two handles are symmetrically hinged on the supporting seat, and the middle part of each handle is hinged with a connecting sheet whose one end is hinged on the guiding seat. Therefore, a crank boosting mechanism is formed in order to realize timely crimping in cable connection. The utility model has the advantages of simple structure, easy manufacture, convenient operation, safe crimping, high work efficiency and low labor intensity. The utility model is suitable for use in cable laying operation.

Description

A kind of cable connection conductor compression jointing tongs of colding pressing

The utility model relates to a kind of power cable laying construction instrument, and refering in particular to is the conductor compression jointing tongs that a kind of power cable is colded pressing and connected.

At present, along with the development of electric utility, the proportion of power cable in urban distribution network increases day by day, and the cable laying environment becomes increasingly complex, and the cable laying amount also increases day by day.Therefore, how to make the suitable complicated execution conditions of cable laying construction instrument and increase work efficiency and reduce labour intensity also just to show important especially, and present mechanical type Press Plier is owing to adopt gear drive, driving force is apart from little, therefore, load mould of every crimping need repeatedly lift handle, and efficient is low, labour intensity is big, and clamp head part is fixed on the vice body and can not arbitrarily rotates, and causes in the cable construction process labour intensity height, speed is slow, brings inconvenience to constructing operation.

The purpose of this utility model is to overcome the deficiency of prior art and provides a kind of easy and simple to handle, and crimping is safe and reliable, high efficiency, and labour intensity is low, and is applicable to the cable of constructing in the complex environment connection conductor compression jointing tongs of colding pressing.

The utility model is to adopt following proposal to realize: it mainly is installed with module by one in it and is set on the guide holder and the binding clip and of axial location which is provided with a slide-bar and passes guide holder and constitute with the supporting seat that module in the binding clip contacts, symmetry is hinged with two handles on the supporting seat, and each hinge joint of the middle part of two handles has an end to be articulated in brace on the guide holder, constitute a crank boosting mechanism, the crimping when connecting with the realization cable.

Concrete structure of the present utility model describes in detail below in conjunction with accompanying drawing:

Accompanying drawing is the half sectional view of the utility model.

See accompanying drawing, the utility model is made up of latch 1,

module

2,3, binding clip 4, guide holder 7, supporting seat 8, handle 9,

handle tube

10,11,12, brace 14.Described

module

2,3 is installed in the chute 5 in the binding clip 4, the end is plugged in 4 liang of side through hole of binding clip and axial location by latch 1, guide holder 7 is plugged in the through hole of binding clip end and axial location, supporting seat 8 one sides are provided with a slide-bar 16 and pass the central through hole of guide holder 7 and contact with module 3, handle 9 one ends symmetry hinge is loaded on the supporting seat 8, the other end is set with the

handle tube

10,11,12 that also can slide mutually by location screw 13 location, brace 14 1 ends are articulated on the guide holder 7 by hinge 15, and the other end is articulated in the middle part of handle 9.

Using method of the present utility model is summarized as follows:

1), because guide holder 7 is plugged in the central through hole in the binding clip 4 and axial location, therefore, binding clip and guide holder can relatively rotate, to adapt to the use without operational environment.

2), because brace links together handle and guide holder, and handle end is hinged on the supporting seat, therefore, constitute a crank boosting mechanism, when handle opened or close up, control supporting seat, slide-bar, module 3 descended or rise, to realize the good purpose of cable crimping in the module.Simultaneously, but because the handle tube slide relative, therefore, can be according to cable model and operational environment, the length of selection handle reaches purpose laborsaving, quick, efficient construction.

In sum, the utility model is simple in structure, and processing and manufacturing is easy, and is easy for operation, and crimping is safe and reliable, high efficiency, and labour intensity is low, is suitable for the use in the cable laying operation.
