Description

本発明は、入出力端子に関し、詳しくは、エンジン発電機、エンジン溶接機、油圧ユニット等に設けられる入出力端子であって、特に、端子板に複数設けられている入出力端子の一つの端子ボルトに複数の電線を接続する際の裸電線を接続する部分の構造に関する。   The present invention relates to an input / output terminal, and more particularly, an input / output terminal provided in an engine generator, an engine welder, a hydraulic unit, etc., and in particular, one terminal of the input / output terminals provided in a plurality on the terminal plate. It is related with the structure of the part which connects a bare electric wire at the time of connecting a some electric wire to a volt | bolt.

エンジン発電機やエンジン溶接機、油圧ユニット等に設けられている出力端子に電線を接続する構造として、端子板に設けた端子ボルトに螺着するナットを締め付けることにより、金具や座金、ワッシャ等の間に電線を挟持する形態が広く用いられている（例えば、特許文献１参照。）。また、筐体に固定された端子に金具を介して電線をビスにて締め付ける構造において、金具の端部をビス側に曲げて電線の挿入を容易にしたものも知られている（例えば、特許文献２参照。）。
実開平７−１５６８号公報 実開平２−７７６７３号公報（第６頁、第４図） As a structure that connects electric wires to output terminals provided in engine generators, engine welders, hydraulic units, etc., by tightening nuts that are screwed into terminal bolts provided on terminal plates, metal fittings, washers, washers, etc. A configuration in which an electric wire is sandwiched between them is widely used (see, for example, Patent Document 1).

Japanese Utility Model Publication No. 7-1568 Japanese Utility Model Publication No. 2-77673 (page 6, FIG. 4)

しかし、特許文献１に記載された入出力端子では、裸電線を接続するときに電線の端末を完全にまとめ上げてから接続部に挿入しなければならず、さらに、入出力端子の位置によっては、無理な姿勢で作業を行う必要があった。また、一つの端子ボルトに２本の電線を接続する際には、通常、電線の間にワッシャ等を介在させて接続するようにしているため、特許文献２に記載されているように、金具の端部を単に折り曲げて拡開させただけでは、隣接する電線の接続が困難になってしまう。特に、圧着端子を結合した電線を隣接させて接続するときには、折り曲げた金具と圧着端子とが干渉してナットやボルトを十分に締め付けられないことがあった。   However, in the input / output terminal described in Patent Document 1, when connecting a bare electric wire, the end of the electric wire must be completely assembled and then inserted into the connection portion, and depending on the position of the input / output terminal, It was necessary to work in an unreasonable posture. Further, when connecting two electric wires to one terminal bolt, since the connection is usually made by interposing a washer or the like between the electric wires, as described in Patent Document 2, If the end of the wire is simply bent and expanded, it becomes difficult to connect adjacent wires. In particular, when connecting electric wires combined with crimp terminals adjacent to each other, the bent metal fittings and the crimp terminals may interfere with each other and the nuts and bolts may not be sufficiently tightened.

そこで本発明は、一つの端子ボルトに複数の電線を接続する際に、裸電線の接続を容易に行えるとともに、圧着端子を結合した電線を隣接させて接続しても十分な締付力で複数の電線を端子ボルトに接続することができる入出力端子を提供することを目的としている。   Therefore, the present invention can easily connect bare wires when connecting a plurality of electric wires to one terminal bolt, and can also connect a plurality of wires with sufficient clamping force even if adjacent wires are connected. It aims at providing the input-output terminal which can connect the electric wire of this to a terminal bolt.

上記目的を達成するため、本発明の入出力端子は、端子板に設けた一つの端子ボルトに複数の電線を接続可能とした入出力端子において、前記端子ボルトに接続される一つの電線の先端を端子ボルトの側方からあらかじめ設定された電線接続位置に案内するための筒状ガイド部を設け、該筒状ガイド部の内面に、端子ボルト側基部から先端に向かって拡開する電線ガイド面を設けるとともに、該一つの電線に隣接して接続される他の電線側の筒状ガイド部外面を、該他の電線を挟持する挟持部材の電線挟持面の延長線よりも突出しない形状としたことを特徴としている。   In order to achieve the above object, the input / output terminal of the present invention is an input / output terminal in which a plurality of electric wires can be connected to one terminal bolt provided on a terminal plate, and the tip of one electric wire connected to the terminal bolt Is provided with a cylindrical guide portion for guiding the wire from the side of the terminal bolt to a predetermined wire connection position, and the inner surface of the cylindrical guide portion expands from the terminal bolt side base toward the tip. The outer surface of the cylindrical guide portion on the other electric wire side connected adjacent to the one electric wire has a shape that does not protrude beyond the extension line of the electric wire holding surface of the holding member that holds the other electric wire. It is characterized by that.

また、本発明の入出力端子は、前記構成において、前記筒状ガイド部が電線の先端を挟持する一対の挟持部材の一側方に設けられ、反端子板側に配置される一方の挟持部材は端子板側が開口した溝形に形成され、端子板側に配置される他方の挟持部材は前記一方の挟持部材の溝内に収納される幅寸法を有する板状体であって、該板状体の長さ方向の一側端部が前記一方の挟持部材から離れる方向に屈曲していることを特徴としている。   In the input / output terminal of the present invention, in the above-described configuration, the cylindrical guide portion is provided on one side of a pair of clamping members that clamp the tip of the electric wire, and is one clamping member disposed on the opposite terminal plate side Is formed in a groove shape having an opening on the terminal plate side, and the other holding member disposed on the terminal plate side is a plate-like body having a width dimension accommodated in the groove of the one holding member, One end of the body in the longitudinal direction is bent in a direction away from the one clamping member.

さらに、本発明の入出力端子は、前記一つの電線が前記端子ボルトに固着された雌ねじ部材の側方に開口した電線挿入口から先端を挿入した状態で雌ねじ部材の反端子板側に螺着されるボルトを締め付けることにより端子ボルトに接続されるものでり、前記筒状ガイド部が前記電線挿入口の外部に、該電線挿入口側基部から先端に向かって拡開した状態で突設していることを特徴としている。   Furthermore, the input / output terminal of the present invention is screwed to the opposite terminal plate side of the female screw member in a state where the tip is inserted from the electric wire insertion opening opened to the side of the female screw member fixed to the terminal bolt. It is connected to the terminal bolt by tightening the bolt, and the cylindrical guide portion protrudes outside the wire insertion port in a state of expanding from the wire insertion port side base to the tip. It is characterized by having.

本発明の入出力端子によれば、端子ボルトに裸電線を接続する場合でも、先端に向かって円錐状又は角錐状に拡開する電線ガイド面を設けた筒状ガイド部によって裸電線の先端を端子ボルトの所定の接続位置に案内することができるので、裸電線の端末を完全にまとめ上げなくても簡単に接続することができる。さらに、端子ボルトが低い位置等に設けられている場合でも、楽な姿勢で電線の接続作業を行うことができる。   According to the input / output terminal of the present invention, even when a bare wire is connected to a terminal bolt, the tip of the bare wire is connected to the tip of the bare wire by a cylindrical guide portion provided with a wire guide surface that expands in a conical shape or a pyramid shape toward the tip. Since it can guide to the predetermined connection position of a terminal volt | bolt, it can connect easily even if it does not gather up the terminal of a bare wire completely. Furthermore, even when the terminal bolt is provided at a low position or the like, the electric wire can be connected in an easy posture.

また、隣接して接続される他の電線側の筒状ガイド部を該他の電線を挟持する挟持部材の電線挟持面の延長線よりも突出しない形状としたことにより、圧着端子を結合した他の電線を隣接させて接続する場合でも、圧着端子と筒状ガイド部とが干渉することがなく、各電線を十分に締付固定することができる。したがって、一つの端子ボルトに、圧着端子を結合した電線と圧着端子を結合しない裸電線とを容易かつ確実に接続することができる。   In addition, the cylindrical guide portion on the side of the other electric wire connected adjacently has a shape that does not protrude beyond the extension line of the electric wire holding surface of the holding member that holds the other electric wire, so that the crimp terminal is joined. Even when adjacent wires are connected, the crimp terminals and the cylindrical guide portion do not interfere with each other, and each wire can be sufficiently fastened and fixed. Therefore, the electric wire combined with the crimp terminal and the bare electric wire not combined with the crimp terminal can be easily and reliably connected to one terminal bolt.

さらに、電線の先端を挟持する一対の挟持部材を溝形の部材と板状の部材とで形成し、板状体の長さ方向一側端部を屈曲させて前記筒状ガイド部を形成することにより、裸電線を案内する筒状ガイド部を簡単に製作することができる。さらに、端子ボルトに固着した雌ねじ部材に側方から電線の先端を挿入するものでは、電線挿入口の外部に筒状ガイド部を突設させるだけでよく、この場合も簡単に製作することができる。   Further, a pair of clamping members for clamping the tip of the electric wire is formed by a groove-shaped member and a plate-like member, and the one end portion in the longitudinal direction of the plate-like body is bent to form the cylindrical guide portion. Thereby, the cylindrical guide part which guides a bare electric wire can be manufactured easily. Further, in the case of inserting the tip of the electric wire from the side into the female screw member fixed to the terminal bolt, it is only necessary to project the cylindrical guide portion outside the electric wire insertion port, and in this case, it can be easily manufactured. .

図１乃至図３は、本発明の入出力端子の第１形態例を示すもので、図１は要部の断面正面図、図２は底面図、図３は構成部材の説明図である。本形態例に示す入出力端子１１は、一つの端子ボルト１２の出力側に２本の電線１３，１４を接続できるように形成されており、一方の電線１３は先端部の被覆を取り除いた裸電線の状態で、他方の電線１４は先端に圧着端子１５を結合した状態で接続するようにしている。   1 to 3 show a first embodiment of an input / output terminal according to the present invention. FIG. 1 is a sectional front view of a main part, FIG. 2 is a bottom view, and FIG. The input / output terminal 11 shown in the present embodiment is formed so that two electric wires 13 and 14 can be connected to the output side of one terminal bolt 12, and one electric wire 13 is a bare wire with the end portion removed. In the state of the electric wire, the other electric wire 14 is connected in a state where the crimp terminal 15 is coupled to the tip.

端子ボルト１２は、端子板１６の通孔１６ａに挿通された状態で、端子板１６を挟んで端子ボルト１２に螺合する回転止め部材１７と固定ナット１８とによって端子板１６に固定されている。なお、回転止め部材１７は、通常は端子ボルト１２の中間部の所定位置に固定されており、端子板１６の背面側に突出した端子ボルト１２には、図示しない入力側の電線が接続される。   The terminal bolt 12 is fixed to the terminal plate 16 by a rotation-preventing member 17 and a fixing nut 18 that are screwed into the terminal bolt 12 with the terminal plate 16 interposed therebetween, while being inserted into the through hole 16 a of the terminal plate 16. . The rotation stop member 17 is normally fixed at a predetermined position in the middle of the terminal bolt 12, and an input-side electric wire (not shown) is connected to the terminal bolt 12 protruding to the back side of the terminal plate 16. .

端子板１６の出力側には、２本の係合ピン１９により回り止めされた前記回転止め部材１７と、被覆を取り除いた電線（以下、裸電線という）１３を挟持する一対の挟持部材である板状金具２０及び溝形金具２１と、圧着端子１５を挟持する一対の挟持部材を構成する前記溝形金具２１及びワッシャ２２と、緩み止めとなるスプリングワッシャ２３と、これらを締付固定する締付ナット２４とが配置されている。   On the output side of the terminal plate 16 are a pair of clamping members that clamp the rotation preventing member 17 that is prevented from rotating by two engagement pins 19 and an electric wire (hereinafter referred to as a bare electric wire) 13 from which the coating has been removed. The plate-shaped metal fitting 20 and the groove-shaped metal fitting 21, the groove-shaped metal fitting 21 and the washer 22 constituting a pair of holding members for holding the crimping terminal 15, the spring washer 23 for preventing the loosening, and the fastening for fastening and fixing them. An attached nut 24 is arranged.

裸電線１３に対して反端子板側に配置される前記溝形金具２１は、端子板１６側が開口した断面コ字状の溝形に形成されており、端子ボルト１２を挿通するボルト挿通孔２１ａは、該溝形金具２１の中央に対して長手方向に変位した位置に設けられている。このボルト挿通孔２１ａに端子ボルト１２を挿通すると、溝形金具２１は、その一側方（下方）が前記回転止め部材１７の一端面（下端面）１７ａよりも突出するように形成されている。   The grooved metal fitting 21 disposed on the side opposite to the terminal plate with respect to the bare wire 13 is formed in a U-shaped groove shape having an opening on the terminal plate 16 side, and a bolt insertion hole 21a through which the terminal bolt 12 is inserted. Is provided at a position displaced in the longitudinal direction with respect to the center of the grooved metal fitting 21. When the terminal bolt 12 is inserted into the bolt insertion hole 21a, the groove-shaped metal fitting 21 is formed such that one side (downward) protrudes from one end surface (lower end surface) 17a of the rotation stop member 17. .

また、裸電線１３に対して端子板側に配置される前記板状金具２０は、前記溝形金具２１の溝内面寸法よりも僅かに小さな幅寸法を有し、溝形金具２１の溝内に収納されて回転不能かつボルト軸方向に移動可能な大きさを有する板状体であって、この板状金具２０のボルト挿通孔２０ａも、前記溝形金具２１と同様に板状金具２０の中央に対して長手方向に変位した位置に設けられ、ボルト挿通孔２０ａに端子ボルト１２を挿通したときに、板状金具２０の長さ方向の一側端部が溝形金具２１と同方向（下方）に突出するように形成されている。さらに、回転止め部材１７の一端面１７ａよりも下方に突出した板状金具２０の一側端部２０ｂは、溝形金具２１から離れる方向、すなわち、端子板１６側に向かって屈曲している。   The plate-shaped metal fitting 20 disposed on the terminal plate side with respect to the bare electric wire 13 has a width dimension slightly smaller than the groove inner surface dimension of the groove-shaped metal fitting 21, and is in the groove of the groove-shaped metal fitting 21. A plate-like body that is housed and cannot be rotated and is movable in the bolt axial direction, and the bolt insertion hole 20a of the plate-like metal fitting 20 has a central portion of the plate-like metal fitting 20 similar to the groove-shaped metal fitting 21. When the terminal bolt 12 is inserted into the bolt insertion hole 20a, one end of the plate-like metal fitting 20 in the longitudinal direction is in the same direction as the grooved metal fitting 21 (downward). ) Protruding. Further, one end portion 20b of the plate-shaped metal fitting 20 protruding downward from the one end surface 17a of the rotation stopper 17 is bent toward the terminal plate 16 side, that is, away from the groove-shaped metal fitting 21.

このように、板状金具２０及び溝形金具２１の一側方を他の回転止め部材１７やワッシャ２２、締付ナット２４等の各部材に対して側方に突出させるとともに、板状金具２０の一側端部を溝形金具２１から離れる方向に向かって屈曲させることにより、板状金具２０と溝形金具２１とに囲まれた部分の内面に端子ボルト側基部から先端に向かって拡開する電線ガイド面２５を設けた筒状ガイド部２６が形成される。   In this way, one side of the plate-shaped metal fitting 20 and the groove-shaped metal fitting 21 is protruded laterally with respect to the other members such as the anti-rotation member 17, the washer 22, the tightening nut 24, and the plate-like metal fitting 20. By bending the one side end portion away from the grooved metal fitting 21, the inner surface of the portion surrounded by the plate-like metal fitting 20 and the grooved metal fitting 21 is expanded from the terminal bolt side base toward the tip. The cylindrical guide part 26 provided with the electric wire guide surface 25 to be formed is formed.

締付ナット２４を緩めた状態で裸電線１３を前記筒状ガイド部２６内に挿入すると、裸電線１３の先端が電線ガイド面２５によって板状金具２０と溝形金具２１との間に案内されて端子ボルト１２の部分まで挿入されるので、裸電線１３の端末が完全にまとめ上げられていなくても、先端をあらかじめ設定された電線接続位置に配置することができる。また、裸電線１３の先端を筒状ガイド部２６に挿入するだけで接続できるので、端子ボルト１２の位置にかかわらず楽な姿勢で裸電線１３の接続作業を行うことができる。   When the bare wire 13 is inserted into the cylindrical guide portion 26 with the tightening nut 24 loosened, the tip of the bare wire 13 is guided between the plate-like metal fitting 20 and the groove-like metal fitting 21 by the electric wire guide surface 25. Therefore, even if the end of the bare wire 13 is not completely assembled, the tip can be arranged at a preset wire connection position. Moreover, since it can connect only by inserting the front-end | tip of the bare wire 13 in the cylindrical guide part 26, the connection operation | work of the bare wire 13 can be performed with an easy attitude | position irrespective of the position of the terminal bolt 12. FIG.

さらに、隣接して接続される電線１４の圧着端子１５を挟持する一方の挟持部材と兼用される溝形金具２１は長さ方向を屈曲させずに、その反端子板側の電線挟持面２１ｂを平面としているので、筒状ガイド部２６の電線１４側の外面が電線挟持面２１ｂと同一面となり、圧着端子１５を挟持したときに圧着端子１５と溝形金具２１とが干渉することがない。   Further, the grooved metal fitting 21 that is also used as one clamping member for clamping the crimping terminal 15 of the adjacent electric wire 14 does not bend in the length direction, and the electric wire clamping surface 21b on the side opposite to the terminal plate is provided. Since it is flat, the outer surface of the cylindrical guide portion 26 on the side of the electric wire 14 is flush with the electric wire holding surface 21b, and the crimp terminal 15 and the grooved metal fitting 21 do not interfere when the crimp terminal 15 is held.

したがって、端子板１６に設けた端子ボルト１２に所定の順序で前記回転止め部材１７から圧着端子１５を含めて締付ナット２４までの各部材を装着した状態で裸電線１３を筒状ガイド部２６内に所定長さ挿入した後、締付ナット２４を締め付けることにより、裸電線１３を容易かつ確実に接続するとともに、電線１４の圧着端子１５も確実に接続することができる。また、接続時の裸電線１３は、板状金具２０及び溝形金具２１の内部に収まった状態となるので、外観上も良好なものとなる。   Therefore, the bare wire 13 is connected to the cylindrical guide portion 26 in a state in which the members from the rotation stop member 17 to the crimping terminal 15 to the tightening nut 24 are attached to the terminal bolt 12 provided on the terminal plate 16 in a predetermined order. After inserting a predetermined length into the wire, the tightening nut 24 is tightened, so that the bare wire 13 can be connected easily and reliably, and the crimp terminal 15 of the wire 14 can also be securely connected. Moreover, since the bare electric wire 13 at the time of connection will be in the state accommodated in the plate-shaped metal fitting 20 and the groove-shaped metal fitting 21, it will become favorable also in an external appearance.

図４乃至図６は、第１形態例の変形例をそれぞれ示す要部の正面図である。なお、以下の説明において、前記第１形態例で示した入出力端子における構成要素と同一の構成要素には、それぞれ同一符号を付して詳細な説明は省略する。   FIG. 4 to FIG. 6 are front views of main parts showing modifications of the first embodiment. In the following description, the same components as those in the input / output terminals shown in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

まず、図４に示すものは、前記第１形態例における板状金具２０を省略し、前記回転止め部材１７の反端子板側面を電線挟持面１７ｂとして使用し、該電線挟持面１７ｂの一側を前記溝形金具２１の突出方向に突出させるとともに、該突出部を溝形金具２１から離れる方向の傾斜面１７ｃとし、該傾斜面１７ｃと溝形金具２１とに囲まれた部分の内面を、端子ボルト側基部から先端に向かって拡開する電線ガイド面２５を設けた筒状ガイド部２６としている。   First, what is shown in FIG. 4 omits the plate-shaped metal fitting 20 in the first embodiment, uses the side surface opposite to the terminal plate of the rotation preventing member 17 as the electric wire holding surface 17b, and one side of the electric wire holding surface 17b. Projecting in the protruding direction of the grooved metal fitting 21, the protruding part is an inclined surface 17 c in a direction away from the grooved metal fitting 21, and the inner surface of the portion surrounded by the inclined surface 17 c and the grooved metal fitting 21 is The cylindrical guide portion 26 is provided with an electric wire guide surface 25 that expands from the terminal bolt side base toward the tip.

図５に示すものは、前記板状金具２０の一側端部を溝形金具２１側が凸となる円弧面２０ｃで溝形金具２１から離れる方向に屈曲させている。また、図６に示すものは、前記板状金具２０の一側端部を溝形金具２１側が凹となる円弧面２０ｄで溝形金具２１から離れる方向に屈曲させている。   In the structure shown in FIG. 5, one end of the plate-shaped metal fitting 20 is bent in a direction away from the groove-shaped metal fitting 21 by an arcuate surface 20c having a convex shape on the groove-shaped metal fitting 21 side. Further, in the structure shown in FIG. 6, one end of the plate-shaped metal fitting 20 is bent in a direction away from the groove-shaped metal fitting 21 by an arcuate surface 20d having a concave shape on the groove-shaped metal fitting 21 side.

図７乃至図９は、本発明の入出力端子の第２形態例を示すもので、図７は要部の断面正面図、図８は側面図、図９は底面図である。本形態例に示す入出力端子は、端子板１６から突出した端子ボルト１２に、径方向の電線挿通孔３１を設けた雌ねじ部材３２を固着し、電線挿通孔３１の一方の開口（電線挿入口）３３から裸電線１３の先端を挿入した状態で、雌ねじ部材３２の反端子板側に螺着される締付ボルト３４を締め付けることにより、該締付ボルト３４の先端で裸電線１３を圧着して端子ボルト１２に接続する構造を有している。   7 to 9 show a second embodiment of the input / output terminal according to the present invention. FIG. 7 is a sectional front view of the main part, FIG. 8 is a side view, and FIG. 9 is a bottom view. In the input / output terminal shown in this embodiment, the female screw member 32 provided with the radial wire insertion hole 31 is fixed to the terminal bolt 12 protruding from the terminal plate 16, and one opening (wire insertion port) of the wire insertion hole 31 is secured. ) With the leading end of the bare wire 13 inserted from 33, the fastening bolt 34 screwed to the opposite terminal plate side of the female screw member 32 is tightened, so that the bare wire 13 is crimped by the tip of the fastening bolt 34. The terminal bolt 12 is connected.

このような構造を有する入出力端子では、前記電線挿入口３３の外部に、該電線挿入口３３側の基部３５ａから先端３５ｂに向かって拡開した状態の筒状ガイド部３５を突設し、その内面の円錐面からなる電線ガイド面３５ｃによって裸電線１３の先端を電線挿通孔３１に案内するように形成する。なお、基部３５ａは、雌ねじ部材３２の外周面に溶接や接着によって固着してもよく、基部３５ａの外径を電線挿通孔３１の内径に対応した寸法に設定し、基部３５ａを電線挿入口３３から電線挿通孔３１の入口部に嵌入あるいは螺合させて雌ねじ部材３２に固着するようにしてもよい。   In the input / output terminal having such a structure, a cylindrical guide portion 35 in a state of expanding from the base portion 35a on the wire insertion port 33 side toward the distal end 35b is projected outside the wire insertion port 33, It forms so that the front-end | tip of the bare electric wire 13 may be guided to the electric wire penetration hole 31 with the electric wire guide surface 35c which consists of the conical surface of the inner surface. The base portion 35a may be fixed to the outer peripheral surface of the female screw member 32 by welding or bonding. The outer diameter of the base portion 35a is set to a dimension corresponding to the inner diameter of the wire insertion hole 31, and the base portion 35a is set to the wire insertion port 33. Alternatively, it may be fixed to the female screw member 32 by being inserted into or screwed into the inlet portion of the electric wire insertion hole 31.

また、本形態例においても、筒状ガイド部３５の外面は、他の電線１４に結合した圧着端子１５を雌ねじ部材３２の突出端にワッシャ３６を介して、あるいは直接、締付ボルト３４で締付固定する際の障害とならないように、他の電線１４を挟持する挟持部材の電線挟持面となる雌ねじ部材３２の突出端面３２ａの延長線３２ｂよりも突出しない形状としておくことにより、雌ねじ部材３２への圧着端子１５の接続を確実に行うことができる。さらに、筒状ガイド部３５の外面を雌ねじ部材３２の外径の範囲内に納めておくことにより、隣接配置される他の入出力端子との間隔を広げる必要がなくなる。   Also in this embodiment, the outer surface of the cylindrical guide portion 35 is fastened with the crimping terminal 15 coupled to the other electric wire 14 to the protruding end of the female screw member 32 via the washer 36 or directly with the fastening bolt 34. The female screw member 32 is formed so as not to protrude from the extension line 32b of the protruding end surface 32a of the female screw member 32 that becomes the electric wire holding surface of the holding member that holds the other electric wires 14 so as not to become an obstacle at the time of fixing.
