Description

本発明は、電線を接続するための接続具にするもので、さらに詳しくは、太さの異なる電線同士あるいは同じ太さの電線同士を容易に接続できる電線接続具に関するものである。   The present invention relates to a connecting tool for connecting electric wires, and more particularly to an electric wire connecting tool that can easily connect electric wires having different thicknesses or electric wires having the same thickness.
従来から、電線同士を接続する接続具の一つに、母線と分岐線を両側で挟持する銅、アルミニウム等の導電性材料からなる上下挟持器を設け、その外側に挟持器より熱膨張係数の低い鉄、ステンレス等の上下押え金具を重ね合わせ、ボルトおよびナットで締め付けることにより、挟圧するようにしたものが知られている(例えば、特許文献1参照)。   Conventionally, an upper and lower clamping device made of a conductive material such as copper or aluminum that clamps a busbar and a branching wire on both sides is provided as one of the connecting tools for connecting wires, and the thermal expansion coefficient of the clamping device is larger than that of the clamping device. There is known a structure in which low pressure iron and stainless steel upper and lower pressing metal fittings are stacked and clamped by tightening with bolts and nuts (for example, see Patent Document 1).
また、別の接続具として、図9、図10に示すように、両側部をC状に曲げたチャンネル部30,30と、両側壁が下から上に拡がる弾性傾斜面31,31を有するウエッジブロック32とを備え、チャンネル部30にケーブル導線33,33を入れ、ボルト34によりC形部材35とウエッジブロック32間を締め付けて接続するものが知られている(例えば、特許文献2参照)。   As another connector, as shown in FIG. 9 and FIG. 10, a wedge having channel portions 30 and 30 having both side portions bent into a C shape and elastic inclined surfaces 31 and 31 having both side walls expanding from the bottom to the top. A block 32 is provided, and cable conductors 33 and 33 are inserted into the channel portion 30 and the C-shaped member 35 and the wedge block 32 are fastened and connected by bolts 34 (see, for example, Patent Document 2).
特公昭37−10116号公報Japanese Examined Patent Publication No. 37-10116 特許第2603546号公報Japanese Patent No. 2603546
しかしながら、上記特許文献1の電線接続具は、上下挟持具に比べて膨張係数のより低い押え金具を使用することにより過熱の抑制効果を生じるが、挟持具の成形が困難であるばかりでなく、押え金具と分離しているため、締め付け作業が煩雑になり、接続作業に時間がかかり作業効率が悪いという問題がある。   However, the wire connector disclosed in Patent Document 1 has an effect of suppressing overheating by using a presser fitting having a lower expansion coefficient than that of the upper and lower clamping tools, but not only is the molding of the clamping tool difficult. Since it is separated from the presser fitting, there is a problem that the tightening work becomes complicated, the connecting work takes time, and the work efficiency is poor.
また、上記特許文献2の電線接続具は、溝部に適合する直径のケーブルについては十分な電気的かつ機械的結合が可能であるが、ケーブルの径が適合する範囲は狭く、その範囲を外れると電気的かつ機械的結合の双方が著しく悪化するという問題点がある。   Moreover, although the electric wire connector of the said patent document 2 is capable of sufficient electrical and mechanical coupling with respect to a cable having a diameter suitable for the groove portion, the range in which the diameter of the cable is suitable is narrow and out of the range. There is a problem that both electrical and mechanical couplings are significantly deteriorated.
そこで、本発明は、上記のような問題点に鑑み開発されたもので、電線の直径を問わず電線同士を容易に接続できる電線接続具を提供することを目的とするものである。   Then, this invention was developed in view of the above problems, and it aims at providing the electric wire connector which can connect electric wires easily irrespective of the diameter of an electric wire.
上記の課題を解決し、その目的を達成するために、本発明に係る電線接続具は、底面部の両側から立ち上がる側壁部を備えた略凹字状の導電性材料からなる電線接続具本体と、前記側壁部に対して接離する方向に移動可能に設けられた複数の挟持部材と、挟持部材をそれぞれ側壁部方向へ付勢させる弾機と、挟持部材の間に介在される可動部材とを備え、前記電線接続具本体は、前記側壁部の内面にそれぞれ電線受止部を有し、前記挟持部材は、前記電線受止部と対向する位置に電線把持部と、前記電線把持部の反対側の位置に側方傾斜面とを有し、前記可動部材は、その底部に前記挟持部材の側方傾斜面と同一方向へ傾斜するテーパー状の下部傾斜面を有しており、前記挟持部材の側方傾斜面と前記可動部材の下部傾斜面とを摺接させることにより前記電線受止部と前記電線把持部とで電線を掴持することを特徴とするものである。   In order to solve the above-described problems and achieve the object, an electric wire connector according to the present invention includes an electric wire connector main body made of a substantially concave conductive material having side wall portions that rise from both sides of a bottom surface portion. A plurality of clamping members provided so as to be movable toward and away from the side wall part, an elastic machine for biasing the clamping members in the direction of the side wall part, and a movable member interposed between the clamping members, The wire connector main body has an electric wire receiving portion on the inner surface of the side wall portion, and the clamping member has an electric wire gripping portion at a position facing the electric wire receiving portion, and the electric wire holding portion. The movable member has a tapered lower inclined surface that is inclined in the same direction as the side inclined surface of the holding member at the bottom thereof. The side inclined surface of the member and the lower inclined surface of the movable member are brought into sliding contact with each other. It is characterized in that gripping the wire between the wire receiving portion and the electrical wire gripping unit by.
これによれば、側壁部の先端部と挟持部材の先端部の間に電線を押し当てて挿入すれば、挟持部材が弾機の付勢力に抗して側壁部から離れる方向に移動し導入口が長さ方向に開口する。電線は、挟持部材が側壁部側に戻ることにより電線把持部と電線受止部とによって挟持されて仮止め状態となる。その後、可動部材を下動させて下部傾斜面と挟持部材の側方傾斜面とを摺接させて押圧すると楔作用の働きにより、挟持部材と側壁部との間の電線を掴持する。弾機の付勢力により仮止め状態を作り、一度の締結作業で電線の接続を可能とするので、接続作業の時間を短縮できるとともに作業効率の向上を実現することができる。   According to this, if the electric wire is pressed and inserted between the front end portion of the side wall portion and the front end portion of the holding member, the holding member moves in a direction away from the side wall portion against the urging force of the ammunition and is introduced. Opens in the length direction. The electric wire is held between the electric wire gripping portion and the electric wire receiving portion when the holding member returns to the side wall portion side, and is temporarily stopped. Thereafter, when the movable member is moved downward to bring the lower inclined surface and the side inclined surface of the holding member into sliding contact with each other and pressed, the electric wire between the holding member and the side wall is gripped by the action of the wedge. Since the temporarily fixed state is created by the urging force of the ammunition and the electric wires can be connected by a single fastening operation, it is possible to reduce the time for the connection operation and to improve the work efficiency.
ここで、前記電線受止部は、電線の周面と同一曲面を持つ半円形状の凹面に形成され、前記電線把持部は、略V字状溝に形成されているのが好ましい。   Here, it is preferable that the electric wire receiving portion is formed in a semicircular concave surface having the same curved surface as the peripheral surface of the electric wire, and the electric wire gripping portion is formed in a substantially V-shaped groove.
これによって、電線の一方の側部が凹面に嵌まり、他方の側部は弾機の付勢力と可動部材の下動による押圧で、略V字状溝に電線を喰い込ませて把持するので、電線が動いたりずれたりすることがなく、確実な接続が可能となる。   As a result, one side of the electric wire is fitted into the concave surface, and the other side is pressed by the urging force of the ammunition and the downward movement of the movable member, so that the electric wire is engulfed and held in the substantially V-shaped groove. The electric wire does not move or shift, and a reliable connection is possible.
ここで、一対の電線受止部および電線把持部と、他方の電線受止部および電線把持部とは、それぞれ大きさが異なるとするのが好ましい。   Here, it is preferable that the pair of the wire receiving portion and the wire gripping portion and the other wire receiving portion and the wire gripping portion have different sizes.
これによって、直径が異なる電線同士の接続ができ、太い電線と細い電線とを適切に接続することが可能となる。   As a result, electric wires having different diameters can be connected to each other, and a thick electric wire and a thin electric wire can be appropriately connected.
ここで、前記電線接続具本体の側壁部上端は内側へ傾斜する先端傾斜面を有し、前記挟持部材は、前記先端傾斜面と反対向きの上部傾斜面を有するのが好ましい。   Here, it is preferable that the upper end of the side wall portion of the electric wire connector main body has a tip inclined surface inclined inward, and the clamping member has an upper inclined surface opposite to the tip inclined surface.
これによって、側壁部の上端の傾斜面と挟持部材の上端の傾斜面とで略逆ハ字状を形成するので、電線を挿入しやすくすることができる。   As a result, a substantially inverted C shape is formed by the inclined surface at the upper end of the side wall portion and the inclined surface at the upper end of the clamping member, so that the electric wire can be easily inserted.
以上説明したように、本発明は、弾機の付勢力による電線把持部と電線受止部との一次挟みで電線を仮止めし、電線の片寄りやズレを確認した後、可動部材を下動させる本締めにより、楔作用の働きで挟持部材を押し付けることになって強力な接続が可能となる。この接続は、たとえ外力などがかかったとしても、外れたりすることがなく、長期の使用に耐え得るものである。また、可動部材と挟持部材は組み立て分解が容易であり、損傷すれば取り替えることが可能であると共に、電線の直径サイズにあったものに取り替えることにより、あらゆる直径の電線にも適用できる。   As described above, according to the present invention, the electric wire is temporarily fixed with the primary pinch between the electric wire gripping portion and the electric wire receiving portion due to the urging force of the ammunition, and after confirming the deviation and deviation of the electric wire, the movable member is moved down. By the final tightening to be moved, the pinching member is pressed by the action of the wedge action, and a strong connection is possible. Even if an external force or the like is applied, this connection does not come off and can withstand long-term use. In addition, the movable member and the clamping member can be easily assembled and disassembled, and can be replaced if damaged. In addition, the movable member and the holding member can be applied to electric wires of any diameter by replacing them with ones that match the diameter size of the electric wires.

以下、本発明に係る電線接続具の実施形態について説明する。
電線接続具本体1は銅やアルミニウム等の導電性材料からなる略凹字状の接続具本体である。この電線接続具本体1には、底面部1aから立ち上がる側壁部1b、側壁部1cが長さ方向に延設されている。なお、側壁部1bと側壁部1cは厚みの異なるものを採用しているが同じ厚みのものでもよい。
Hereinafter, embodiments of the electric wire connector according to the present invention will be described.
The wire connector main body 1 is a substantially concave connector main body made of a conductive material such as copper or aluminum. In the electric wire connector main body 1, side wall portions 1b and side wall portions 1c rising from the bottom surface portion 1a are extended in the length direction. In addition, although the side wall part 1b and the side wall part 1c employ | adopt the thing from which thickness differs, the thing of the same thickness may be sufficient.
側壁部1bの上部内面には太い電線2の周面と同一曲面を持つ半円形状の凹面4と、側壁部1cの上部内面には細い電線3の周面と同一曲面を持つ半円形状の凹面4とからなる電線受止部5が長さ方向に設けられ、電線2、電線3がそれぞれ嵌るように形成されている。先端傾斜面6は側壁部1b、側壁部1cの上端が下方に向かって傾斜する側壁部先端の傾斜面であり、電線2,電線3を導入しやすくなっている。ボルト孔7は底面部1aの中央部に穿設された螺子孔であり、軸孔8は側壁部1b,側壁部1cの下方の前寄りと後寄りに設けられた孔である。   The semicircular concave surface 4 having the same curved surface as the peripheral surface of the thick electric wire 2 is formed on the upper inner surface of the side wall portion 1b, and the semicircular shape having the same curved surface as the peripheral surface of the thin electric wire 3 is formed on the upper inner surface of the side wall portion 1c. An electric wire receiving portion 5 including the concave surface 4 is provided in the length direction, and is formed so that the electric wire 2 and the electric wire 3 are fitted respectively. The tip inclined surface 6 is an inclined surface at the tip of the side wall portion in which the upper ends of the side wall portion 1b and the side wall portion 1c are inclined downward, so that the electric wire 2 and the electric wire 3 can be easily introduced. The bolt hole 7 is a screw hole drilled in the central portion of the bottom surface portion 1a, and the shaft hole 8 is a hole provided on the front side and the rear side below the side wall portion 1b and the side wall portion 1c.
挟持部材9は、側壁部1bおよび側壁部1cにそれぞれ対向する位置にコイルスプリング10を介して配置された部材で、弾機であるコイルスプリング10の付勢力によって、幅方向、すなわち、側壁部1bおよび側壁部1cに対して接離する方向へ移動可能になっている。この挟持部材9は、電線受止部5と対向する位置に、略V字状に形成されたV字状溝11で構成される電線把持部12を備えている。この挟持部材9は、電線接続具本体1の底面部1aと摺動する底部13と、電線把持部12と、先端傾斜面6の傾斜方向と逆方向に傾斜する上部傾斜面14と、電線把持部12と反対側に位置して上部傾斜面14と逆方向へ傾斜する面である側方傾斜面15と、コイルスプリング10を受ける垂直部16とで構成されている。   The clamping member 9 is a member disposed via the coil spring 10 at a position facing the side wall portion 1b and the side wall portion 1c, respectively, and in the width direction, that is, the side wall portion 1b by the urging force of the coil spring 10 that is a bullet machine. In addition, it can move in a direction in which it is in contact with or away from the side wall 1c. The clamping member 9 includes an electric wire gripping portion 12 configured by a V-shaped groove 11 formed in a substantially V shape at a position facing the electric wire receiving portion 5. The clamping member 9 includes a bottom portion 13 that slides with the bottom surface portion 1a of the electric wire connector main body 1, an electric wire gripping portion 12, an upper inclined surface 14 that is inclined in a direction opposite to the inclination direction of the tip inclined surface 6, and an electric wire gripper. The side inclined surface 15 is a surface that is located on the opposite side of the portion 12 and is inclined in the direction opposite to the upper inclined surface 14, and a vertical portion 16 that receives the coil spring 10.
切込み部17は、挟持部材9の側方傾斜面15を長さ方向に浅く切り込んで設けられて形成された切込みで、この切込み部17に可動部材18の下部傾斜面22が収まり、前後方向に抜け出ないようになっている。この挟持部材9の上部傾斜面14と側壁部1b、側壁部1cの先端傾斜面6とはそれぞれ反対方向に傾斜しており、上部傾斜面14と先端傾斜面6とが略逆ハ字状になって電線2,電線3を挿入しやすくなっている。   The cut portion 17 is a cut formed by cutting the side inclined surface 15 of the holding member 9 shallowly in the length direction. The lower inclined surface 22 of the movable member 18 is accommodated in the cut portion 17 so that It is designed not to escape. The upper inclined surface 14 of the sandwiching member 9 and the side wall portion 1b and the front end inclined surface 6 of the side wall portion 1c are inclined in opposite directions, and the upper inclined surface 14 and the front end inclined surface 6 are formed in a substantially inverted C shape. It becomes easy to insert the electric wire 2 and the electric wire 3.
可動部材18は挟持部材9と挟持部材9の間に介在されている台形状の部材で、天板19の両側面20に連設され底面21に向かって次第に幅狭くなるテーパー状の下部傾斜面22を備えている。なお、ボルト挿通孔23は天板19の中央に穿設したボルトを挿通するための孔である。この可動部材18の下部傾斜面22は、それぞれ挟持部材9の側方傾斜面15と同一方向に傾斜しており、可動部材18を下動させることにより挟持部材9の側方傾斜面15と摺接して楔作用を生じさせ、側壁部1b,側壁部1cの電線受止部5と挟持部材9の電線把持部12とで電線2,電線3を強固に掴持する。   The movable member 18 is a trapezoidal member interposed between the sandwiching members 9, and is a tapered lower inclined surface that is connected to both side surfaces 20 of the top plate 19 and gradually becomes narrower toward the bottom surface 21. 22 is provided. The bolt insertion hole 23 is a hole for inserting a bolt drilled in the center of the top plate 19. The lower inclined surface 22 of the movable member 18 is inclined in the same direction as the side inclined surface 15 of the holding member 9, and the movable member 18 is moved downward to slide with the side inclined surface 15 of the holding member 9. In contact with each other, a wedge action is generated, and the electric wires 2 and 3 are firmly held by the side wall portion 1b, the electric wire receiving portion 5 of the side wall portion 1c, and the electric wire gripping portion 12 of the clamping member 9.
軸24は側壁部1b,側壁部1cの両方の下端前寄りと後方寄りに穿設された軸孔8へ通す軸であり、挟持部材9と挟持部材9の間に横架し、軸24の外周面にコイルスプリング10を嵌装することにより、挟持部材9は側壁部1b,側壁部1c側に向かって付勢されている。   The shaft 24 is a shaft that passes through the shaft hole 8 that is drilled near the front and rear ends of both the side wall 1b and the side wall 1c. By fitting the coil spring 10 on the outer peripheral surface, the clamping member 9 is biased toward the side wall 1b and the side wall 1c.
このように構成した電線接続具本体1と挟持部材9と可動部材18とを組み合わせて電線接続具にする。すなわち、電線接続具本体1の側壁部1b,側壁部1cとの間、左右に複数の挟持部材9を配し、その間にコイルスプリング10を介在させ、軸孔8から軸24を入れ挟持部材9に通せばコイルスプリング10の付勢力によって挟持部材9が側壁部1b,側壁部1cにそれぞれ当接する状態になる。そして、左右の挟持部材9の間に可動部材18を介在させて、ボルト25にスプリングワッシャー26とワッシャー27を嵌めてボルト挿通孔23に挿通し、先端部をボルト孔7に螺合させて構成するものである。   The electric wire connector main body 1, the clamping member 9, and the movable member 18 configured as described above are combined to form an electric wire connector. That is, a plurality of clamping members 9 are arranged on the left and right sides between the side wall 1b and the side wall 1c of the electric wire connector main body 1, and the coil spring 10 is interposed between them, and the shaft 24 is inserted from the shaft hole 8 to hold the clamping member 9. If it passes, it will be in the state which the clamping member 9 contact | abuts to the side wall part 1b and the side wall part 1c by the urging | biasing force of the coil spring 10, respectively. Then, the movable member 18 is interposed between the left and right clamping members 9, the spring washer 26 and the washer 27 are fitted into the bolt 25, the bolt is inserted into the bolt insertion hole 23, and the tip is screwed into the bolt hole 7. To do.
この状態で、側壁部1b,側壁部1cの先端傾斜面6および挟持部材9の上部傾斜面14で構成される略V字に凹んだ部分の上方から電線2,電線3を押し入れると、挟持部材9はコイルスプリング10の付勢力に抗して側壁部1b,側壁部1cから離れる方向に移動して開口し、電線2,電線3を電線受止部5と電線把持部12とで挟んで仮止めした状態となる。この仮止め状態から、ボルト25を螺締していけば、可動部材18の下部傾斜面22と挟持部材9の側方傾斜面15とが摺接し、可動部材18の楔作用により挟持部材9が側壁部1b,側壁部1c側に強く押圧されることになり、電線2,電線3を強力に掴持することができる。従来と異なり、締め付け作業は一度で済むので、接続作業の時間短縮と、作業効率の向上を図ることができる。   In this state, when the electric wires 2 and 3 are pushed in from above the substantially V-shaped portion formed by the side wall portion 1b, the tip inclined surface 6 of the side wall portion 1c, and the upper inclined surface 14 of the holding member 9, The member 9 moves against the urging force of the coil spring 10 to move away from the side wall portion 1b and the side wall portion 1c, and opens the electric wire 2 and the electric wire 3 between the electric wire receiving portion 5 and the electric wire gripping portion 12. It will be in the state temporarily stopped. If the bolt 25 is screwed from this temporarily fixed state, the lower inclined surface 22 of the movable member 18 and the side inclined surface 15 of the holding member 9 are in sliding contact with each other, and the holding member 9 is moved by the wedge action of the movable member 18. It will be strongly pressed by the side wall part 1b and the side wall part 1c side, and the electric wire 2 and the electric wire 3 can be held firmly. Unlike the conventional method, the tightening work is only required once, so that the time required for the connection work can be shortened and the work efficiency can be improved.
電線の接続を解除するには、締めつけられていたボルト25を緩めて、上述の仮止め状態に戻す。電線2,電線3を上方に引き上げれば、可動部材18が上動し、挟持部材9はコイルスプリング10の弾発力に抗して側壁部1b,側壁部1cから離れる方向に引かれて口が開いて電線2,電線3が引き抜かれて接続が解除される。   In order to release the connection of the electric wire, the bolt 25 which has been tightened is loosened to return to the above-described temporarily fixed state. When the electric wires 2 and 3 are pulled upward, the movable member 18 moves upward, and the clamping member 9 is pulled in a direction away from the side wall portion 1b and the side wall portion 1c against the elastic force of the coil spring 10, thereby opening the mouth. Is opened, the electric wires 2 and 3 are pulled out, and the connection is released.
以上、本発明における電線接続具の実施形態に基づいて説明したが、本発明はこれらに限定されるものではなく、本発明の目的を達成し、且つ発明の要旨を逸脱しない範囲内で種々の設計変更が可能である。   As mentioned above, although it demonstrated based on embodiment of the wire connector in this invention, this invention is not limited to these, In the range which achieves the objective of this invention and does not deviate from the summary of invention, it is various. Design changes are possible.
例えば、上記実施形態においては、一対の電線受止部および電線把持部と、もう一対の電線受止部および電線把持部の大きさを異ならせることにより、電線が支持される部分に差を設けて太い電線と細い電線を接続可能にする例を示したが、両方の大きさを同一にすることを妨げるものではない。   For example, in the above-described embodiment, a difference is provided in the portion where the wire is supported by making the sizes of the pair of wire receiving portions and the wire gripping portion different from those of the other pair of wire receiving portions and the wire gripping portion. Although an example of enabling connection of a thick and thin electric wire has been shown, it does not prevent both sizes from being the same.
また、電線受止部も電線の周面と同一曲面を持つ半円形状の凹面で形成した例を示したが、電線把持部と同様の略V字状の溝で形成する等してもよい。   Moreover, although the example which formed the electric wire receiving part also with the semicircular concave surface which has the same curved surface as the surrounding surface of an electric wire was shown, you may form with the substantially V-shaped groove | channel similar to an electric wire holding part. .
