Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a holder (holder) for pulling and holding two electric wires to be connected in close proximity to each other in a position where they can be connected to each other during electrical work.

[Conventional technology] Conventionally, when connecting two wires to each other in order to extend wires or install or replace a transformer or other electrical equipment in electrical work, the tips of both wires to be connected are Strip off the insulation covering of the part to expose it as a bare wire, insert it inward through the openings at both ends of a connection sleeve called a compression terminal so that the exposed bare wire part is brought together, and then compress it. Squeeze the terminal to electrically connect both wires. At this time, until the compression terminal is compressed and crushed, there is a loose fit between the inner hole of the compression terminal and the tip wire, which makes insertion easier. However, even if a slight force is applied, one or both of the wires will come out of the compression terminal. Therefore, two workers are required at all times for the connection; one person acts as an assistant and pulls and holds the ends of both wires in contact or close together, while the other person acts as the main worker and performs the connection work itself. It depended on the work method of carrying out.

[Issues to be solved by the invention] As described above, since wire connection work is always carried out as a work group of two people, one of the two people in the group may not be able to participate in the work for some reason. In addition to this, it is necessary to take measures such as hiring replacement personnel and assigning workers who do not work in pairs to other tasks other than connection, and the labor costs for connection work are also high, so a solution is required. Ta.

[Means for Solving the Problems] In order to solve these problems, the present invention provides a holder 2 which is made up of two members, one end of which is connected with a pin and the other end of which can be opened and closed like a bivalve shell. Prepare a pair of holders for wire connection work by connecting both holders with a wire that serves as a drawstring, open each holder, and hold the ends of the wires to be connected with the top screw. Tighten and secure each wire to each wire, pull both wires together so that they can be inserted into the respective end openings of the compression terminal that will serve as the connecting body, operate the stopper to stop the wires from returning, compress the compression terminal, and remove the wires. This makes it possible for one worker to complete the connection work.

[Example] Fig. 1 shows W 1 and W ₁ of two electric wires to be connected to a pair of electric wire connection work holders 10, 10' of the present invention.
It is a side view showing a state where it is attached to the end of _W2 ,
The tip C of one electric wire W ₁ is approached until the coating is peeled off and it is inserted into the opening (right side in the figure) of the compression sleeve 20 (compression terminal), and the other electric wire
The distal end C' of W ₂ with the coating stripped off has already been inserted from the left end of the compression connection sleeve 20 to the connection position.

Reference numeral 18 indicates that both holders 10, 10' are connected through the opening of the hollow shaft pin 13 which becomes the opening/closing shaft of each holder 10, 10'.
10', and after each holder is attached to the respective electric wire and fixed with a thumbscrew, one electric wire integrated with the holder 10 is connected.
It serves as a pull cord to pull W ₁ to a position where it can be connected. For this reason, a head 18' having a diameter larger than the opening of the hollow shaft 13 is attached to one end of the wire 18 (on the right side in the figure), so that when the wire 18 is pulled to the left, the holder 10 is moved to the left. force is transmitted to the holder 10.

Reference numeral 30 denotes a stopper, which is located outside the left end of the holder 10' and has a passage hole 32 through which the wire 18 can freely pass, and which fixes the position when the holders 10 and 10' reach the wire connection position. This acts to prevent the wire 18 from being pulled back.

FIG. 2A is a front view of the holder 10 as seen along the - line in FIG. They are a pair of holding members that can be swung, and in the center of both of them in the vertical direction, there are both holding members 1.
Semicircular grooves 14 are formed on the inner surfaces of the electric wires 1 and 12 that face each other, and are used to clamp and hold the electric wires therebetween.

The free end of the holding member 12 is provided with the hollow shaft pin 1.
A shaft pin 15 parallel to 3 is inserted, and the shaft pin 1
A wing nut 17 is screwed to the wing screw rod 16 with the wing 5 as an axis.

FIG. 2B is a side view of the holding member 12 taken along arrow B in FIG. belongs to.

FIG. 3 is a front view of the stopper seen along the - line in FIG. The inner diameter is large enough to allow the stopper 30 and the wire 18 to move freely relative to each other.

The block 31 has an axis slightly away from the axis of the wire passage hole 32, and the wire passage hole 32
A tapered hole 33 is formed in a direction perpendicular to the wire passage hole 32, and a substantially intermediate portion of this tapered hole in the axial direction is formed so as to partially intersect with the wire passage hole 32. 3
4 is a taper pin 34 having the same inclination angle that is inserted into this taper hole 33, and a thread is cut at the tip end on the side where the outer diameter becomes smaller. The wire 18 advances in the narrowing direction and protrudes into the area of the wire passage hole 32, compressing the wire 18 and fixing it to the holder 10'.

The procedure for using the wire connection holder according to the present invention will be described below.

1. Loosen the wing nuts of the holders 10, 10' and open the holders.

2 Set holders on both electric wires _W1 and _W2 .

3 Tighten the thumbscrews and attach both wires W ₁ and W ₂ and holder 1.
0 and 10' are respectively fixed.

4. Insert one end of the sleeve (compression terminal) 20 for compression connection into one end of one electric wire _W2 .

5. Pull the wire (pull string), pull the other wire ₁ , and insert it into the connection sleeve 20.

7 Perform compression connection work for both wires to be connected.
