Abstract

PURPOSE:To execute the connecting work of wires with one worker, by forming a rectangle with longer rod units and shorter frame units confronted with each other, and by fixing a one side wire on the one side frame unit, to retain the frame unit for moving another side wire along the rod unit, firmly. CONSTITUTION:A rectangle is formed with parallel longer rod units 1, 2 and parallel shorter frame units 3, 4 confronted with each other. By a retaining unit 6 set on the frame unit 3, a one-side wire K with a stepping-peeled-off insulation at the end section is retained. A moving frame unit 5 having gears 9a, 9b fitted on rack gears 1a, 2a arranged inside the rod units 1, 2 confronted with each other is set. By the retaining unit 7 of the moving frame unit 7, another side wire K' with the peeled-off insulation at the end section is retained. The moving unit 5 is moved in the direction of an arrow head by an operating handle 10, and the tip of the wire K' is inserted into a sleeve S, and after that, the wire is soldered or the sleeve S is pressure-welded to. As a result, even the connecting work of thick cables can be easily executed by one worker.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention mainly relates to connecting the ends of two electric wires at a predetermined relative position when connecting two electric wires by crimping or soldering through a connecting sleeve. This invention relates to a wire gathering tool for connecting wires used for pulling and holding wires at a distance.

<Prior art> Conventionally, in order to connect two electric wires by crimping or soldering through a connecting sleeve, one of the workers grasps the two electric wires to be connected and presses the wires together. Holding the position where the bare wire with the sheath removed is inserted into the connection sleeve, one of the other workers presses the connection sleeve with a pressure tool and crimps the wire, or one of the workers does the same to insert the bare wire into the connection sleeve. A method has been taken in which the parts are held in a facing position or in a parallel contact position, and another worker performs the soldering work.

Therefore, in the conventional manual connection of this type of electric wire, two people usually worked together as a team. In particular, in cases where the electric wire is already suspended on a utility pole or on the roof of a required building, or where one of the electric wires is suspended, two-person work is essential.

<Problems to be Solved by the Invention> Therefore, in the past, there were problems in that work efficiency was poor and two-person work on utility poles was dangerous.

Therefore, in order to solve these conventional problems, the present invention aims to develop a work tool that can perform this type of wire connection work efficiently in large-scale work, and with relatively little danger.
