Description

The present invention relates to a conductor part twisting jig for twisting a plurality of conductor parts exposed from an insulator part.

In electrical work and DIY, it is necessary to twist conductors of electric wires. For example, after twisting two conductors together, they are crimped with a closed-end connector.
In such a case, the fingertips may be damaged because the conductor is generally pinched and twisted with the fingertips. Twisting may become weak due to concerns about scratches on the fingertips.
If it is a factory where there is a large amount of work to twist the conductor part, it is possible to use an electric or pneumatic automatic wire twister (see Japanese Patent Application Laid-Open No. 2018-099015). We cannot use such a device.

Machines for twisting conductors of electric wires are used in factories, but at present there are no small devices that can be easily handled by amateurs.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a compact and easy-to-handle conductor twisting jig capable of easily twisting conductors of electric wires.

A conductor twisting jig according to the present invention is a conductor twisting jig for twisting a plurality of conductors, wherein one end of a cylindrical body is an opening into which a plurality of conductors can be inserted, The opening is formed substantially flat, the longitudinal dimension of the opening is set so that a plurality of conductors to be twisted can be inserted side by side, and the lateral dimension of the opening is the length of one conductor. and smaller than the sum of the diameters of the plurality of conductors to be twisted together. are twisted together.

According to the jig for twisting conductors according to the present invention, the conductors are naturally twisted together simply by inserting and rotating a plurality of conductors. For this reason, even an amateur can easily handle it without using a conventional large-scale mechanical device. Moreover, there is a great advantage that the conductor can be manually twisted together without damaging the fingertips or the like.

First, electric wire 200 having conductor portion 220 to be twisted by conductor portion twisting jig 100 according to the embodiment of the present invention will be described.
This electric wire 200 is a general one configured by covering a conductor portion 210 with an insulator portion 210 . The conductor part 220 includes a single wire type consisting of one conductor and a stranded wire type consisting of a plurality of conductors twisted together. Yes.
Needless to say, when twisting the conductor portion 220, the insulator portion 210 is removed and the conductor portion 220 is exposed.

A conductor portion twisting jig 100 according to the embodiment of the present invention is a conductor portion twisting jig for twisting a plurality of conductor portions 220, and one end side of a tubular body is capable of inserting a plurality of conductor portions 220. The opening 110 is formed substantially flat, and the longitudinal dimension of the opening 110 is set so that a plurality of conductors 220 to be twisted can be inserted side by side. The transverse dimension of the portion 110 is set to be larger than the diameter of one conductor portion 220 and smaller than the sum of the diameters of the plurality of conductor portions 220 to be twisted together. When rotated relative to the conductor portion 220, the conductor portions 220 are twisted together.

This conductor part twisting jig 100 is obtained by, for example, crushing one end side of a metal cylindrical body into a substantially flat shape, more specifically, in such a way that a short side of a rectangular shape protrudes outward. An opening 110 into which the conductor 220 is inserted is formed on the side.
A plurality of conductor portions 220 to be twisted can be inserted into this opening portion 110 . Specifically, the longitudinal dimension of the opening 110 is set so that the plurality of conductors 220 to be twisted can be inserted in a horizontal arrangement.
This longitudinal dimension is not simply set larger than the sum of the diameters of the plurality of conductor portions 220 to be twisted together. That is, as shown in FIG. 5 and the like, when inserting the plurality of conductor portions 220 into the opening portion 111, the insulator portions 210 of the wires 200 are kept in contact with each other. Although the body portion 210 has been removed, the conductor portions 220 are in a state of not contacting each other. The longitudinal dimension of the opening 110 is not the sum of the diameters of the plurality of conductors 220 to be twisted, but is set to a dimension that allows the plurality of conductors 220 to be inserted side by side. Become.

On the other hand, the lateral dimension of the opening 110 is set larger than the diameter of one conductor 220 and smaller than the sum of the diameters of the plurality of conductors 220 to be twisted together.

That is, if two conductors 220 are to be twisted together, as shown in FIG. The hand dimension should be set larger than the diameter of the two conductors 220 and smaller than the sum of the diameters of the two conductors 220 .
If the three conductor portions 220 are twisted together, it becomes as shown in FIG. 2(B).

As shown in FIG. 1, the opening 110 is gradually enlarged in the lateral direction toward the insertion side. That is, in order to make it easier to insert the plurality of conductors 220 into the opening 110, the opening 110 is formed wider in the lateral direction.

In the above description, the opening 110 is formed by pressing the short sides of the rectangle so as to protrude outward, but it is needless to say that the opening may be simply rectangular.

Further, the conductor part twisting jig 100 has a non-slip tube 120 fitted on the opposite side of the opening 110 .
As shown in FIG. 5, a plurality of conductors 220 are twisted together by placing a thumb, forefinger and middle finger on the tube 120 and rotating the conductor twisting jig 100 .

A procedure for using the conductor portion twisting jig 100 configured in this way will be described.
First, the insulator portion 210 of the wire 200 to be twisted is removed to expose the conductor portion 220 . The electric wires 200 with the conductor portions 220 exposed are arranged side by side. At that time, the insulator portion 210 which is not removed is kept in contact.
In this state, the conductor portion 220 is inserted into the opening portion 110 of the conductor portion twisting jig 100 . Note that the insulating part 210 is not inserted into the opening 110 (see FIGS. 3A and 4A).

In this state, one hand holds the insulator part 210 of the electric wire 200, and the other hand rotates the conductor part twisting jig 100 while extracting it in the direction opposite to the conductor part 220 (Fig. 3(B)). and FIG. 4(B)).

When the conductor part twisting jig 100 is rotated, as shown in FIG. Since the diameter is set to be smaller than the sum of the diameters of the plurality of conductor portions 220, the conductor portions 220 are naturally twisted together by maintaining the horizontal alignment of the conductor portions 220 inside the conductor portion twisting jig 100 (FIG. 3). (C) and FIG. 4(C)).

When the conductor part twisting jig 100 is rotated, the conductor part 220 on the root side, that is, on the side closer to the insulator 210 tries to maintain the side-by-side state because the insulator part 210 is pressed by hand, but the conductor part on the tip side Since the conductor part 220 maintains a horizontal state inside the conductor part twisting jig 100 and is rotated while the conductor part twisting jig 100 is pulled out, the conductor part 220 is twisted from the tip side.

The number of conductor portions 220 that are twisted together at one time can be adjusted by appropriately setting the dimensions of the opening portion 110 .

Further, in the above description, the conductor part twisting jig 100 was manually rotated, but it is also possible to use it by connecting it to the rotating shaft of a rotating tool such as an existing electric screwdriver on the opposite side of the opening. be.
A rotary tool can be used to twist the conductor portion 220 more quickly and easily. Moreover, existing electric screwdrivers can be easily used at construction sites and DIY situations.

In the above description, the conductor part twisting jig 100 deforms a cylindrical body made of metal, but it is not limited to being made of metal. It goes without saying that it may be configured.
