Description

本発明は、絶縁体部から露出された導体部を複数本捩り合わせる導体部捩り治具に関する。 The present invention relates to a conductor part twisting jig for twisting a plurality of conductor parts exposed from an insulator part.

電気工事やＤＩＹにおいて電線の導体部を捩り合わせる必要がある。例えば、２本の導体部を捩り合わせた後、閉端接続子で圧着する場合等である。
かかる場合、一般には導体部を指先で摘んで捩るため、指先を傷めるおそれがある。指先の傷が気になって捩り合わせが弱くなることもある。
導体部を捩り合わせる作業が大量にある工場等であれば、電気式やエアー式の自動電線捩り機（特開２０１８－０９９０１５号公報参照）を使用することもできるが工事現場やＤＩＹ等の場面ではそのような機械器具を用いることもできない。 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.

特開２０１８－０９９０１５号公報JP 2018-099015 A

電線の導体部を捩り合わせる機械器具は、工場で使用するようなものはまだしも、小型で素人でも簡単に取り扱えるような機器は存在しないのが現状である。 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.

本発明は、上記事情に鑑みて創案されたもので、電線の導体部を簡単に捩り合わせることができる小型かつ扱いやすい導体部捩り治具を提供することを目的にしている。 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.

本発明に係る導体部捩り治具は、複数本の導体部を捩り合わせる導体部捩り治具であって、筒状体の一端側が複数本の導体部を挿入可能な開口部となっており、当該開口部は、略扁平に形成され、開口部の長手方向寸法は捩り合わせるべき複数本の導体部を横並びにした状態で挿入可能に設定され、開口部の短手方向寸法は一本の導体部の直径より大きくかつ捩り合わせるべき複数本の導体部の直径の和より小さく設定されており、複数本の導体部を挿入した状態で導体部に対して相対的に回転させると、導体部同士が捩り合わされるようになっている。 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.

本発明に係る導体部捩り治具によると、複数本の導体部を挿入し、回転させるだけで自然と導体部が捩り合わされる。このため、従来のような大がかりな機械器具を使用することなく、素人でも簡単に取り扱える。しかも指先等傷めることなく手動で導体部を捩り合わせることができるという大きなメリットがある。 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.

まず、本発明の実施の形態に係る導体部捩り治具１００によって捩り合わされる導体部２２０を有する電線２００について説明する。
この電線２００は、導体部２１０を絶縁体部２１０で被覆することで構成される一般的なものである。導体部２２０には１本の導体からなる単線タイプや、複数本の導体を縒り合わせて構成されたより線タイプがあるが、本発明に係る導体部捩り治具１００は、より線タイプの電線に対応している。
なお、導体部２２０を捩り合わせる際には、絶縁体部２１０を除去して導体部２２０を露出させた状態で行うことはいうまでもない。 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.

本発明の実施の形態に係る導体部捩り治具１００は、複数本の導体部２２０を捩り合わせる導体部捩り治具であって、筒状体の一端側が複数本の導体部２２０を挿入可能な開口部１１０となっており、当該開口部１１０は、略扁平に形成され、開口部１１０の長手方向寸法は捩り合わせるべき複数本の導体部２２０を横並びにした状態で挿入可能に設定され、開口部１１０の短手方向寸法は一本の導体部２２０の直径より大きくかつ捩り合わせるべき複数本の導体部２２０の直径の和より小さく設定されており、複数本の導体部２２０を挿入した状態で導体部２２０に対して相対的に回転させると、導体部２２０同士が捩り合わされるようにはなっている。 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.

この導体部捩り治具１００は、例えば金属製の筒状体の一端側を略扁平、詳しくは長方形の短辺側を外側に向かって突出させたように押しつぶしたものであって、この押しつぶした側を導体部２２０を挿入する開口部１１０としている。
この開口部１１０は、捩り合わせるべき複数本の導体部２２０が挿入可能になっている。具体的には、開口部１１０の長手方向寸法は捩り合わせるべき複数本の導体部２２０を横並びにした状態で挿入可能に設定されている。
この長手方向寸法は、単に捩り合わせるべき複数本の導体部２２０の直径の和より大きく設定されているのではない。すなわち、図５等に示すように、複数本の導体部２２０を開口部１１１に挿入する際、電線２００の絶縁体部２１０同士を接触させた状態で行われるので、導体部２２０を被覆した絶縁体部２１０は除去されてはいるが導体部２２０同士は接触しない状態となっている。開口部１１０の長手方向寸法は、捩り合わせるべき複数本の導体部２２０の直径の和ではなく、複数本の導体部２２０を横並びにした状態で挿入可能となるような寸法に設定されることになる。 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.

一方、開口部１１０の短手方向寸法は、一本の導体部２２０の直径より大きくかつ捩り合わせるべき複数本の導体部２２０の直径の和より小さく設定されている。 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.

すなわち、２本の導体部２２０を捩り合わせるのであれば、図２（Ａ）に示すように、開口部１１０の長手方向寸法は２本の導体部２２０が横並びで挿入可能に設定され、しかも短手方向寸法は２本の導体部２２０の直径よりは大きくかつ２本の導体部２２０の直径の和より小さく設定される必要がある。
３本の導体部２２０を捩り合わせるのであれば、図２（Ｂ）に示すようになる。 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).

かかる開口部１１０は、図１に示すように、短手方向は挿入側に向かって徐々に拡大されている。すなわち、開口部１１０への複数本の導体部２２０の挿入をより容易にするために、開口部１１０は短手方向においてより広く形成されているのである。 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.

なお、開口部１１０は、上述の説明では、長方形の短辺側を外側に向かって突出させたように押しつぶしたものとしたが、単に長方形状であってもよいことはいうまでもない。 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.

さらに、この導体部捩り治具１００は、開口部１１０の反対側には滑り止めのチューブ１２０が嵌め込まれている。
図５に示すように、このチューブ１２０に親指、人指し指、中指をかけて導体部捩り治具１００を回転させることで複数本の導体部２２０を捩り合わせるのである。 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 .

このように構成された導体部捩り治具１００の使用手順を説明する。
まず、捩り合わせるべき電線２００の絶縁体部２１０を除去して導体部２２０を露出させる。導体部２２０が露出された電線２００を横並びにする。その際、除去されていない絶縁体部２１０は接触させておく。
この状態で導体部２２０を導体部捩り治具１００の開口部１１０に挿入する。なお、絶縁体部２１０までは開口部１１０に挿入しない（図３（Ａ）及び図４（Ａ）参照）。 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).

この状態で横並びの電線２００の絶縁体部２１０を一方の手で抑えておき、もう一方の手で導体部捩り治具１００を導体部２２０の反対方向に抜きながら回転させる（図３（Ｂ）及び図４（Ｂ）参照）。 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)).

導体部捩り治具１００を回転させると、図２に示すように、導体部捩り治具１００の開口部１１０の短手方向寸法が、一本の導体部２２０の直径寸法より大きくかつ捩り合わせるべき複数本の導体部２２０の直径寸法の和より小さく設定されているため、導体部捩り治具１００の内部で導体部２２０が横並びを維持することにより導体部２２０が自然と捩り合わせられる（図３（Ｃ）及び図４（Ｃ）参照）。 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)).

導体部捩り治具１００を回転させると、根元側、すなわち絶縁体２１０に近い側の導体部２２０は絶縁体部２１０が手で押さえられているため横並び状態を維持しようとするが、先端側の導体部２２０は導体部捩り治具１００の内部での横並び状態を維持し、しかも導体部捩り治具１００が抜きながら回転されるため、先端側の導体部２２０から捩り合わせられることになる。 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.

なお、一度に捩り合わされる導体部２２０の本数は、開口部１１０の寸法を適宜設定することにより調整することができる。 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 .

また、上述の説明では導体部捩り治具１００を手で回転させたが、開口部の反対側に、例えば既存の電動ドライバーのような回転工具の回転軸に連結して使用することも可能である。
回転工具を使用すれば、より早くかつ簡単に導体部２２０を捩り合わせることができる。しかも、既存の電動ドライバーであれば工事現場やＤＩＹの場面でも簡単に使用することができる。 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.

なお、上述の説明では、導体部捩り治具１００は、金属製の筒状体を変形させているとしたが、金属製に限定されることはなく、合成樹脂、セラミック等の他の素材から構成されてもよいことはいうまでもない。 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.
