Abstract

The utility model relates to a pair of hydraulic clippers for lead, which is for an electronic lead and an electric apparatus lead. The utility model comprises a pressure jointing molding clipper head, a hydraulic system, a flexible handle and a fixed handle. The part of an upper clipper mouth and a lower clipper mouth of the pressure jointing molding clipper head is of a symmetrical shape, and is of an ellipse shape after being oppositely connected. The utility model has the advantages of convenient operation and high work efficiency. An upper creasing and a lower creasing can be pressed out symmetrically after a pressure jointing and the lead connected need not be inversed repeatedly. The length of the pressure jointing pipe can be shortened by the great pressure jointing pulling force and materials can be saved.

Description

Hydraulic pressure join clippers for lead

The utility model relates to the hydraulic conductor compression jointing instrument of a kind of electric power, electrical equipment lead.

In the prior art, lead in electric power, the electric equipment connects, and has a kind ofly to finish by hydraulic conductor compression jointing tongs.This clamps by crimping shaping binding clip, hydraulic system, and flexible handle and fixed handle are formed.Wherein the upper and lower jaw of crimping shaping binding clip is an asymmetry, and it is dark to be a side, and a side is shallow.A shallow side is the fan-shaped circular arc less than 180 °, and a dark side is to be the outer end of semi arch at root, be extended with one section straight wall again, and the longitudinal cross-section of jaw is cydariform.Using this cramp joint line, is quilt to be connect the two ends lead penetrate in the aluminium hydraulic pressed connecting pipe, however with pincers along aluminium hydraulic pressed connecting pipe axially, whenever the pincers that are spaced a distance are pressed once, with aluminium hydraulic pressed connecting pipe crimp, after pincers are pressed, dark jaw one side is not stayed impression on aluminium hydraulic pressed connecting pipe, only stay impression in shallow jaw one side.Thereby use this Press Plier, must be when per twice pincers be pressed 180 ° of angles of counter-rotating, could guarantee both to be connected firmly, damage wires not again, this pincers operation is very inconvenient, and needs than the aluminium hydraulic pressed connecting pipe of length and more pressure mouth.

The purpose of this utility model provides a kind of hydraulic conductor compression jointing tongs product that can stay upper and lower two impressions at a pincers pressure place of aluminium hydraulic pressed connecting pipe, to overcome weak point of the prior art.

The purpose of this utility model is to realize like this.

Hydraulic conductor compression jointing tongs comprises crimping shaping binding clip, hydraulic system, flexible handle and fixed handle.Upper and lower jaw (1,2) part in its crimping shaping binding clip is a symmetric shape, and the involutory rear center of jaw forms the Long Circle hole.

Below in conjunction with embodiment and accompanying drawing, the utility model is described in detail.

Fig. 1 crimping shaping binding clip schematic diagram;

The joint schematic diagram that Fig. 2 crimping is finished;

This Press Plier is except that crimping shaping binding clip is different with Press Plier of the prior art, and all the other are all identical with existing Press Plier, and the upper and lower associated jaw portion shape of crimping shaping binding clip is identical, and the involutory back of jaw interstitial hole is Long Circle, and the longitudinal section also is a cydariform.

The joint of the utility model crimping, it presses mouth is the impression of upper and lower symmetry.It is original 1/3 that its aluminium hydraulic pressed connecting pipe length can only be equivalent to, and the wire tension after the crimping surpasses original technology, damage wires not again simultaneously, and, all can satisfy the requirement of standard through the test of terminal resistance value.

The utility model is easy to operate, need not the lead that reverses in the work, can once extrude two impressions, has improved operating efficiency.Can the crimping steel reinforced aluminium conductor, aluminum steel etc.

Claims

1, a kind of hydraulic conductor compression jointing tongs, comprise: crimping shaping binding clip, hydraulic system, flexible handle and fixed handle, of the present utility modelly be characterised in that the upper and lower associated jaw portion in the crimping shaping binding clip is a symmetric shape, the involutory rear center of jaw forms the Long Circle hole.
