Description

本発明は、速結端子装置に関するものである。   The present invention relates to a quick connection terminal device.

従来、スイッチやコンセントのような配線器具においては、器体に設けた電線挿入孔を通して器体内に導入された電線を接続するために速結端子装置が広く用いられている。この種の速結端子装置は従来周知であって、スイッチにおける接点やコンセントにおける刃受などと電気的に接続された端子板と、端子板との間で電線（導体）を狭持して電線と端子板を電気的に接続すると同時に電線を鎖錠して抜け止めする錠ばねと、器体に設けた操作孔を通してドライバような工具で操作されて錠ばねによる鎖錠を解除する解除釦とで構成されている。   2. Description of the Related Art Conventionally, in a wiring device such as a switch or an outlet, a quick connection terminal device is widely used to connect an electric wire introduced into a container through an electric wire insertion hole provided in the container. This type of quick connection terminal device is well known in the art, and the electric wire (conductor) is sandwiched between the terminal plate and the terminal plate electrically connected to the contact of the switch or the blade holder of the outlet, etc. A lock spring that electrically connects the terminal plate and locks the electric wire at the same time, and a release button that releases the lock by the lock spring operated by a tool such as a driver through an operation hole provided in the body. It consists of

ところが上記の従来の速結端子装置は、電線が確実に接続されているのか否かが外部から分からないため、施工者に対して不安感を与えるという問題や、解除釦の操作に工具が必要であるため、電線の取り外し作業が煩わしいという問題があった。   However, since the above-mentioned conventional quick connection terminal device does not know from the outside whether or not the electric wire is securely connected, there is a problem of giving anxiety to the installer and a tool is required for operating the release button. Therefore, there is a problem that the work of removing the electric wires is troublesome.

これに対して本出願人は、工具を使わずに手動で操作可能な解除レバーで錠ばねによる鎖錠を解除するとともに当該解除レバーによって電線の接続完了表示を行うようにした速結端子装置を既に提案している（例えば、特許文献１参照）。   On the other hand, the applicant of the present invention has disclosed a quick-connect terminal device in which a lock by a lock spring is released with a release lever that can be operated manually without using a tool, and a wire connection completion display is performed with the release lever. It has already been proposed (see, for example, Patent Document 1).

かかる従来例は、図３０に示すように端子板１０と、錠ばね２０と、解除レバー３０とで構成される。端子板１０は、短冊状の主片１１と、主片１１の長手方向に沿った一方の端縁から後方へ垂下された一対の接触片１２と、主片１１の長手方向に沿った他方の端縁から後方へ垂下された当接片１３とを有し、弾性を有する帯状の金属板を加工して主片１１、接触片１２、当接片１３が一体に形成される。接触片１２には電線の挿入方向（図３０における上下方向）に沿った両端部において電線を押圧する一対の押圧部１２ａ，１２ｂと、上側の押圧部１２ｂの先を当接片１３から離れる向きに曲げ起こしてなる被係止部１２ｃとが設けられ、押圧部１２ｂと主片１１の間には、配線器具の器体１００の底壁に貫設されている電線挿入孔１０１と対向し電線が挿通される挿通部１４が形成されている。   Such a conventional example includes a terminal plate 10, a lock spring 20, and a release lever 30 as shown in FIG. 30. The terminal plate 10 includes a strip-shaped main piece 11, a pair of contact pieces 12 that are hung backward from one edge along the longitudinal direction of the main piece 11, and the other of the other along the longitudinal direction of the main piece 11. The main piece 11, the contact piece 12, and the contact piece 13 are integrally formed by processing an elastic band-shaped metal plate. The contact piece 12 has a pair of pressing portions 12a and 12b that press the electric wire at both end portions along the insertion direction of the electric wire (vertical direction in FIG. 30), and a direction in which the tip of the upper pressing portion 12b is separated from the contact piece 13. And a locked portion 12c that is bent and raised, and a wire between the pressing portion 12b and the main piece 11 faces the wire insertion hole 101 penetrating the bottom wall of the container body 100 of the wiring device. The insertion part 14 into which is inserted is formed.

錠ばね２０は、弾性を有する帯状の金属板を略Ｊ字状に曲げ加工してなり、端子板１０の主片１１並びに当接片１３に当接する鈎形の導通片２１と、導通片２１の下端より略Ｕ字状に曲げ形成されたばね片２２とを有し、電線に当接して抜け止めするばね片２２の先端が鎖錠部となる。かかる錠ばね２０は、主片１１と当接片１３に導通片２１を当接させるとともにばね片２２を接触片１２と対向させる形で端子板１０の内側に配置される。そして、電線挿入孔１０１から挿入される電線を端子板１０の接触片１２と錠ばね２０のばね片２２との間で狭持するとともに鎖錠部（ばね片２２の先端）を電線に当接することで抜け止めすることができる。   The lock spring 20 is formed by bending a belt-shaped metal plate having elasticity into a substantially J shape, and has a bowl-shaped conductive piece 21 that contacts the main piece 11 and the contact piece 13 of the terminal plate 10, and a conductive piece 21. The tip of the spring piece 22 that has a spring piece 22 bent in a substantially U shape from the lower end of the wire and abuts against the electric wire to prevent it from coming off becomes a locking part. The lock spring 20 is disposed inside the terminal plate 10 in such a manner that the conducting piece 21 is brought into contact with the main piece 11 and the contact piece 13 and the spring piece 22 is opposed to the contact piece 12. And the electric wire inserted from the electric wire insertion hole 101 is clamped between the contact piece 12 of the terminal board 10 and the spring piece 22 of the lock spring 20, and the locking part (the tip of the spring piece 22) is brought into contact with the electric wire. Can be prevented.

解除レバー３０は合成樹脂成形品からなり、棒状の操作部３１と、矩形板状であって操作部３１とほぼ平行に配置された係止部３２と、操作部３１と係止部３２の長手方向両端同士を連結する連結部３３，３３と、連結部３３，３３より各々側方へ突出する腕部３４，３４と、腕部３４，３４の先端部分より内側に突出する軸部３５，３５と、軸部３５，３５先端面の中央寄りの位置から突出する突台状の押動部３６，３６とが一体に形成されている。   The release lever 30 is made of a synthetic resin molded product, has a rod-like operation portion 31, a rectangular plate-like engagement portion 32 that is disposed substantially parallel to the operation portion 31, and the length of the operation portion 31 and the engagement portion 32. Connecting portions 33, 33 that connect both ends in the direction, arm portions 34, 34 that protrude laterally from the connecting portions 33, 33, and shaft portions 35, 35 that protrude inward from the tip portions of the arm portions 34, 34. And the projection parts 36 and 36 which protrude from the position near the center of shaft part 35 and 35 front end surface are integrally formed.

上述のように構成される従来例では、電線２００が接続されていない状態においては、図３０（ｃ）に示すように係止部３２が端子板１０の被係止部１２ｃに係止（ラッチ）する回動位置まで解除レバー３０が回動させてある（以下、この回動位置を「初期位置」と呼ぶ）。解除レバー３０が初期位置にあるときは錠ばね２０のばね片２２の両端部が一対の押動部３６，３６に押動されて鎖錠部（ばね片２２の先端）が接触片１２から離れる向きに撓んだ状態にある。このときばね片２２のばね力によって解除レバー３０が反操作方向（図３０における反時計回り）に弾性付勢されるが、係止部３２が端子板１０の被係止部１２ｃに係止しているために解除レバー３０は初期位置に保持されることになる。   In the conventional example configured as described above, when the electric wire 200 is not connected, the locking portion 32 is locked (latched) to the locked portion 12c of the terminal board 10 as shown in FIG. The release lever 30 is rotated to the rotation position (hereinafter referred to as “initial position”). When the release lever 30 is in the initial position, both ends of the spring piece 22 of the lock spring 20 are pushed by the pair of pushing portions 36, 36, and the lock portion (the tip of the spring piece 22) is separated from the contact piece 12. It is in a state of bending in the direction. At this time, the release lever 30 is elastically biased in the counter-operation direction (counterclockwise in FIG. 30) by the spring force of the spring piece 22, but the locking portion 32 is locked to the locked portion 12c of the terminal board 10. Therefore, the release lever 30 is held at the initial position.

そして、電線挿入孔１０１を通して電線２００の導体２０１を接触片１２とばね片２２との間に導入すると、挿通部１４を通して導体２０１の先端が解除レバー３０の係止部３２に当接し、係止部３２を押し上げて係止部３２と被係止部１２ｃとのラッチ状態を解除する。すると、ばね片２２のばね力で弾性付勢されていた解除レバー３０が反操作方向に回動し、ばね片２２先端の鎖錠部が導体２０１に当接することによって電線２００が抜け止めされるとともにばね片２２のばね力によって導体２０１が接触片１２に弾接する。さらに導体２０１は一対の押圧部１２ａ，１２ｂによってばね片２２の方へ押圧され、鎖錠部と一対の押圧部１２ａ，１２ｂの押圧力が均衡して電線２００が狭持される。   Then, when the conductor 201 of the electric wire 200 is introduced between the contact piece 12 and the spring piece 22 through the electric wire insertion hole 101, the tip of the conductor 201 comes into contact with the engaging portion 32 of the release lever 30 through the insertion portion 14, The part 32 is pushed up to release the latched state of the locking part 32 and the locked part 12c. Then, the release lever 30 that is elastically biased by the spring force of the spring piece 22 rotates in the counter-operation direction, and the lock portion at the tip of the spring piece 22 comes into contact with the conductor 201 to prevent the electric wire 200 from coming off. At the same time, the conductor 201 elastically contacts the contact piece 12 by the spring force of the spring piece 22. Furthermore, the conductor 201 is pressed toward the spring piece 22 by the pair of pressing portions 12a and 12b, and the pressing force of the locking portion and the pair of pressing portions 12a and 12b is balanced to hold the electric wire 200.

一方、電線２００が接続された状態で操作部３１を上方へ押し上げるように操作すれば、軸部３５，３５を支点にして解除レバー３０が接続時と反対方向（図３０における時計回り）に回動し、押動部３３，３３が錠ばね２０のばね片２２を押圧して導体２０１に当接している鎖錠部（ばね片２２の先端）を導体２０１から離すようにばね片２２を撓ませて電線２００の引き抜きが可能となる。   On the other hand, if the operation unit 31 is pushed upward while the electric wire 200 is connected, the release lever 30 rotates in the opposite direction (clockwise in FIG. 30) with the shaft portions 35 and 35 as fulcrums. The spring pieces 22 are bent so that the locking portions 33 and 33 press the spring pieces 22 of the lock spring 20 and the lock portions (tips of the spring pieces 22) that are in contact with the conductor 201 are separated from the conductor 201. Therefore, the electric wire 200 can be pulled out.

而して上記従来例では、電線２００との接続が完了すると解除レバー３０の操作部３１が初期位置よりも下方の位置に移動することで電線の接続完了を表示することができ、しかも、電線２００の接続を解除するための解除レバー３０を電線２００の接続完了表示に兼用することで部品点数の増加を抑えることができる。
特開２００６−１２６３４号公報 Thus, in the above conventional example, when the connection with the electric wire 200 is completed, the operation part 31 of the release lever 30 moves to a position below the initial position, so that the completion of the connection of the electric wire can be displayed. An increase in the number of parts can be suppressed by using the release lever 30 for releasing the connection of 200 as a connection completion display of the electric wire 200.
JP 2006-12634 A

しかしながら上記従来例においては、電線２００の接続を解除するために解除レバー３０を操作すると、図３０（ａ）に示すように係止部３２が電線２００の導体２０１に当接するため、解除レバー３０が導体２０１に沿ってせり上がり、電線２００が引き抜かれた後に係止部３２が被係止部１２ｃに係止できず、解除レバー３０が全くフリーな状態となってしまう（図３０（ｂ）参照）。従って、再度電線２００を接続するためには、解除レバー３０を操作して係止部３２を被係止部１２ｃに係止させて初期位置に戻す必要があった（図３０（ｃ）参照）。   However, in the above conventional example, when the release lever 30 is operated to release the connection of the electric wire 200, the locking portion 32 comes into contact with the conductor 201 of the electric wire 200 as shown in FIG. Rises along the conductor 201, and after the electric wire 200 is pulled out, the locking portion 32 cannot be locked to the locked portion 12c, and the release lever 30 becomes completely free (FIG. 30B). reference). Therefore, in order to connect the electric wire 200 again, it is necessary to operate the release lever 30 to lock the locking portion 32 to the locked portion 12c and return to the initial position (see FIG. 30C). .

本発明は上記事情に鑑みて為されたものであり、その目的は、電線の接続を解除した後に何ら操作をすること無しに電線を再度接続する際に接続完了状態を表示することができる速結端子装置を提供することにある。   The present invention has been made in view of the above circumstances, and its purpose is a speed at which a connection completion state can be displayed when reconnecting a wire without performing any operation after releasing the connection of the wire. It is in providing a connection terminal apparatus.

接続完了表示部材４は合成樹脂成型品からなり、図３に示すように円柱状の主部４０と、主部４０の周面から互いに略直交する向きに突設された一対の腕部４０ａ，４０ｂと、一方の腕部４０ａより主部４０の軸方向と平行に突出する丸棒状の表示部４１と、他方の腕部４０ｂより表示部４１と平行に突出する角柱状の当接部４２と、主部４０の端面より表示部４１並びに当接部４２と反対方向へ突出する円柱状の支持部４３とが一体に形成されている。   The connection completion display member 4 is made of a synthetic resin molded product, and as shown in FIG. 3, a columnar main portion 40 and a pair of arm portions 40 a projecting from the peripheral surface of the main portion 40 in directions substantially orthogonal to each other. 40b, a round bar-like display portion 41 that protrudes in parallel with the axial direction of the main portion 40 from one arm portion 40a, and a prism-shaped contact portion 42 that protrudes in parallel with the display portion 41 from the other arm portion 40b. A columnar support portion 43 that protrudes in the opposite direction to the display portion 41 and the contact portion 42 from the end surface of the main portion 40 is integrally formed.

ここで、本実施形態では各端子板１０に対して送り配線用を含めて速結端子装置がそれぞれ２つずつ設けられ、これら２つの速結端子装置が各端子板１０並びに錠ばね２０とともにボディ１００ａの長手方向両側に設けられている端子板収納室１０２，１０２に各々並べて収納される。ボディ１００ａの側面には端子板収納室１０２と通じる縦溝１０４が設けられており、縦溝１０４を通して操作部６３を器体１００の外側に露出させるとともに、軸部６０を端子収納室１０２に設けた軸受け台（図示せず）に載置した状態で解除レバー６がボディ１００ａに組み込まれる（図５参照）。そして、図４（ａ）に示すように各一対の接触片１２と錠ばね２０のばね片２２との間に解除レバー６の軸部６０および押動部６２，６２が挿入されるようにして、端子板１０並びに錠ばね２０を端子収納室１０２に組み込むと、解除レバー６の軸部６０が軸受け台に載置されるとともに、押動部６２，６２が錠ばね２０のばね片２２に当接することで解除レバー６が回動自在に支持される。   Here, in this embodiment, two each of the quick connection terminal devices are provided for each terminal plate 10 including those for the feed wiring, and these two quick connection terminal devices together with each terminal plate 10 and the lock spring 20 are provided in the body. 100a is housed side by side in the terminal board storage chambers 102, 102 provided on both sides in the longitudinal direction of 100a. A vertical groove 104 communicating with the terminal plate storage chamber 102 is provided on the side surface of the body 100 a, and the operating portion 63 is exposed to the outside of the container 100 through the vertical groove 104, and a shaft portion 60 is provided in the terminal storage chamber 102. The release lever 6 is incorporated into the body 100a in a state of being placed on a bearing base (not shown) (see FIG. 5). As shown in FIG. 4A, the shaft portion 60 and the pushing portions 62, 62 of the release lever 6 are inserted between each pair of contact pieces 12 and the spring piece 22 of the lock spring 20. When the terminal plate 10 and the lock spring 20 are assembled in the terminal storage chamber 102, the shaft portion 60 of the release lever 6 is placed on the bearing base, and the pushing portions 62 and 62 contact the spring pieces 22 of the lock spring 20. The release lever 6 is rotatably supported by contact.

そして、主片１１に設けられた切り欠き孔１１ａに表示部４１を挿通するとともに当接部４２を挿通部１４に挿通するようにして接続完了表示部材４が組み込まれ、コイルばね５の一端部が支持部４３に外挿され、コイルばね５の他端が、ボディ１００ａと結合されて器体１００を構成する箱形のカバー１００ｂに設けられたばね受け座（図示せず）に嵌め込まれることで接続完了表示部材４が電線の挿入方向（図１における上下方向）において移動自在に支持される。すなわち、接続完了表示部材４はコイルばね５のばね力によって常時下方に弾性付勢されており、電線が接続されていない状態では主部４０が端子板１０の主片１１に当接する位置（以下、接続未完了位置という。）で静止している。ここで、ボディ１００ａ底面に窓孔１０５が貫設されており、電線が接続されていない状態では端子板１０の切り欠き孔１１ａに挿通された表示部４１の先端部分が窓孔１０５を通して器体１００の外に突出しており（図２参照）、このように表示部４１の先端部分が窓孔１０５を通して器体１００外へ突出することで電線が接続されていない状態を表示している。   Then, the connection completion display member 4 is incorporated so that the display portion 41 is inserted into the notch hole 11 a provided in the main piece 11 and the contact portion 42 is inserted into the insertion portion 14, and one end portion of the coil spring 5 is installed. Is inserted into the support portion 43, and the other end of the coil spring 5 is fitted into a spring seat (not shown) provided on a box-shaped cover 100b which is coupled to the body 100a and constitutes the body 100. The connection completion display member 4 is supported movably in the electric wire insertion direction (vertical direction in FIG. 1). That is, the connection completion display member 4 is always elastically biased downward by the spring force of the coil spring 5, and the position where the main portion 40 abuts against the main piece 11 of the terminal plate 10 (hereinafter referred to as “wire” is not connected). , Called a connection incomplete position). Here, the window hole 105 is formed through the bottom surface of the body 100 a, and when the electric wire is not connected, the distal end portion of the display unit 41 inserted through the notch hole 11 a of the terminal plate 10 passes through the window hole 105 and the body. It protrudes out of 100 (see FIG. 2), and the state where the electric wire is not connected is displayed by the tip portion of the display unit 41 protruding out of the body 100 through the window hole 105 in this way.

そして、器体１００の電線挿入孔１０１を通して電線２００の導体２０１を端子板１０の接触片１２と錠ばね２０のばね片２２との間に挿入すると、ばね片２２の先端（鎖錠部）が導体２０１に食い込むことによって電線２００が抜け止めされるとともに、ばね片２２のばね力によって導体２０１が接触片１２に弾接する。さらに導体２０１は一対の押圧部１２ａ，１２ｂによってばね片２２の方へ押圧され、ばね片２２と一対の押圧部１２ａ，１２ｂの押圧力が均衡して電線２００が狭持される。また導体２０１の先端が挿通部１４に挿通されている接続完了表示表示部材４の当接部４２に当たり、当接部４２を上向きに押圧する。このとき当接部４２が導体２０１の押し込み力を受け、コイルばね５のばね力に抗して接続完了表示表示部材４が上向きに移動する。その結果、導体２０１を正規の位置まで挿入すると、図５（ｂ）に示すように接続完了表示表示部材４の表示部４１が窓孔１０５内に退避する位置（以下、接続完了位置という。）まで移動するので、表示部４１を器体１００の外から視認できなくなって電線２００が端子板１０と接続されたこと（接続完了）が表示されることになる。   When the conductor 201 of the electric wire 200 is inserted between the contact piece 12 of the terminal plate 10 and the spring piece 22 of the lock spring 20 through the electric wire insertion hole 101 of the vessel body 100, the tip (locking portion) of the spring piece 22 is inserted. The electric wire 200 is prevented from coming off by biting into the conductor 201, and the conductor 201 is elastically contacted with the contact piece 12 by the spring force of the spring piece 22. Further, the conductor 201 is pressed toward the spring piece 22 by the pair of pressing portions 12a and 12b, and the pressing force of the spring piece 22 and the pair of pressing portions 12a and 12b is balanced to hold the electric wire 200. Further, the tip of the conductor 201 hits the contact portion 42 of the connection completion display display member 4 inserted through the insertion portion 14 and presses the contact portion 42 upward. At this time, the contact portion 42 receives the pushing force of the conductor 201, and the connection completion display display member 4 moves upward against the spring force of the coil spring 5. As a result, when the conductor 201 is inserted to the proper position, the display portion 41 of the connection completion display display member 4 is retracted into the window hole 105 as shown in FIG. 5B (hereinafter referred to as a connection completion position). Therefore, the display unit 41 cannot be viewed from the outside of the container 100 and the electric wire 200 is connected to the terminal board 10 (connection complete) is displayed.

一方、電線２００を引き抜く際には、解除レバー６の操作部６３を上向きに押し上げるように操作すると、軸部６０を支点にして解除レバー６が回動し、押動部６２，６２が錠ばね２０のばね片２２を押圧して導体２０１に食い込んでいる鎖錠部を導体２０１から離すようにばね片２２を撓ませるから、電線２００の引き抜きが可能になる。電線２００が引き抜かれると、接続完了表示表示部材４の当接部４２を上向きに押圧する力が無くなるから、コイルばね５のばね力によって接続完了表示表示部材４が接続未完了位置に移動し、表示部４１の先端部分が窓孔１０５から器体１００の外へ突出することで接続未完了状態が表示されることになる。   On the other hand, when pulling out the electric wire 200, if the operation part 63 of the release lever 6 is pushed upward, the release lever 6 is rotated with the shaft part 60 as a fulcrum, and the pushing parts 62 and 62 are locked springs. Since the spring piece 22 is bent so as to separate the lock portion that presses the 20 spring pieces 22 and bites into the conductor 201 away from the conductor 201, the electric wire 200 can be pulled out. When the electric wire 200 is pulled out, the force that presses the contact portion 42 of the connection completion display display member 4 upward disappears. Therefore, the connection completion display display member 4 is moved to the connection incomplete position by the spring force of the coil spring 5. The front end portion of the display unit 41 protrudes from the window hole 105 to the outside of the container 100, so that the connection incomplete state is displayed.

このように本実施形態では、端子板１０と電線２００との接続が完了すると、接続完了表示部材４の表示部４１が器体１００の窓孔１０５内に退避する位置（接続完了位置）に移動するから、表示部４１が窓孔１０５から器体１００の外へ突出しているか否かで電線２００の接続完了表示を視覚的に確認することができる。しかも、解除レバー６を操作して電線２００を電線挿入孔１０１から引き抜くと付勢部（コイルばね５）に付勢されている接続完了表示部材４が接続完了位置から接続未完了位置へ自動的に復帰するため、従来例のように電線２００の接続を解除した後に何ら操作をすること無しに電線２００を再度接続する際に接続完了状態を表示することができる。   As described above, in the present embodiment, when the connection between the terminal board 10 and the electric wire 200 is completed, the display unit 41 of the connection completion display member 4 moves to a position (connection completion position) where it is retracted into the window hole 105 of the container body 100. Therefore, the connection completion display of the electric wire 200 can be visually confirmed based on whether or not the display unit 41 protrudes from the window hole 105 to the outside of the container body 100. In addition, when the release lever 6 is operated to pull out the electric wire 200 from the electric wire insertion hole 101, the connection completion display member 4 urged by the urging portion (coil spring 5) is automatically moved from the connection completion position to the connection incomplete position. Therefore, the connection completion state can be displayed when the electric wire 200 is connected again without performing any operation after releasing the connection of the electric wire 200 as in the conventional example.

（実施形態２）
図６〜図９を参照して本発明の実施形態２を説明する。但し、本実施形態は接続完了表示部材４に特徴があり、その他の構成については実施形態１と共通である。従って、実施形態１と共通の構成要素には同一の符号を付して適宜図示並びに説明を省略する。 (Embodiment 2)
A second embodiment of the present invention will be described with reference to FIGS. However, this embodiment is characterized by the connection completion display member 4, and other configurations are the same as those of the first embodiment. Accordingly, the same components as those in the first embodiment are denoted by the same reference numerals, and illustration and description thereof are omitted as appropriate.

実施形態１においては、付勢部（コイルばね５）が端子板１０に対して接続完了表示部材４と反対側（図５における上側）に配置されているため、電線の挿入方向における接続完了表示部材４の配置スペースが大きくなってしまうという欠点がある。   In the first embodiment, since the biasing portion (coil spring 5) is arranged on the side opposite to the connection completion display member 4 (upper side in FIG. 5) with respect to the terminal plate 10, the connection completion display in the wire insertion direction is performed. There exists a fault that the arrangement space of the member 4 will become large.

これに対して本実施形態は、コイルばね５の一端部を支持する支持部４４を表示部４１の略中央に設けている。この支持部４４は、表示部４１の軸方向と直交する方向へ突出する突出片４４ａと、突出片４４の主部４０と対向する面から主部４０に向かって起立する円柱状の支持片４４ｂとからなる。そして、図６並びに図８に示すように一端部が支持片４４ｂに外挿されて支持されるとともに他端部が端子板１０の主片１１に当接することでコイルばね５が端子板１０の内側に圧縮状態で保持されることになる。   In contrast, in the present embodiment, a support portion 44 that supports one end portion of the coil spring 5 is provided in the approximate center of the display portion 41. The support portion 44 includes a protruding piece 44 a that protrudes in a direction orthogonal to the axial direction of the display portion 41, and a columnar support piece 44 b that stands from the surface of the protruding piece 44 that faces the main portion 40 toward the main portion 40. It consists of. As shown in FIGS. 6 and 8, the coil spring 5 is connected to the terminal plate 10 by supporting one end portion of the terminal plate 10 by being extrapolated to the support piece 44 b and contacting the other end portion to the main piece 11 of the terminal plate 10. It will be held inside in a compressed state.

ここで、接続完了表示部材４を端子板１０に組み付ける手順について、図９を参照して詳細に説明する。まず、当接部４２が主部４０を挟んで挿通部１４と対向する向きで表示部４１並びに支持部４４を端子板１０の主片１１に設けられた切り欠き孔１１ａに挿通する（図９（ａ），（ｂ）参照）。続いて、当接部４２が挿通部１４と重なる位置まで主部４０を略１８０度回転させ（図９（ｃ），（ｄ）参照）、最後に当接部４２を挿通部１４に挿通させて接続完了表示部材４の端子板１０への組み付けが完了する。但し、接続完了表示部材４を端子板１０に組み付ける際、予め支持部４４にコイルばね５の一端部を支持させておくことが必要である。   Here, the procedure for assembling the connection completion display member 4 to the terminal board 10 will be described in detail with reference to FIG. First, the display portion 41 and the support portion 44 are inserted into the notch hole 11a provided in the main piece 11 of the terminal board 10 in such a direction that the contact portion 42 faces the insertion portion 14 with the main portion 40 interposed therebetween (FIG. 9). (See (a) and (b)). Subsequently, the main portion 40 is rotated approximately 180 degrees until the contact portion 42 overlaps the insertion portion 14 (see FIGS. 9C and 9D), and finally the contact portion 42 is inserted through the insertion portion 14. Thus, the assembly of the connection completion display member 4 to the terminal board 10 is completed. However, when the connection completion display member 4 is assembled to the terminal board 10, it is necessary to support the one end portion of the coil spring 5 in advance on the support portion 44.

而して本実施形態においても実施形態１と同様に、電線２００が接続されていない状態ではコイルばね５のばね力で接続完了表示部材４が接続未完了位置で静止し、表示部４１の先端部分が窓孔１０５を通して器体１００の外に突出することで電線が接続されていない状態を表示するのに対し、電線２００が電線挿入孔１０１を通して正規の位置まで挿入されて端子板１０と接続されると導体２０１の先端から当接部４２に押し込み力を受けた接続完了表示部材４が、コイルばね５のばね力に抗して接続完了位置まで移動することで電線２００の接続完了が表示されることになる。しかも本実施形態では、付勢部（コイルばね５）が接続完了表示部材４に設けられた支持部４４と端子板１０との間に支持されるため、接続完了表示部材４の支持部４３と器体１００との間にコイルばね５を支持する実施形態１と比較して電線の挿入方向における接続完了表示手段の配置スペースを減らすことができるという利点がある。   Thus, also in the present embodiment, as in the first embodiment, in a state where the electric wire 200 is not connected, the connection completion display member 4 is stopped at the connection incomplete position by the spring force of the coil spring 5, and the tip of the display unit 41 The portion protrudes out of the container body 100 through the window hole 105 to indicate a state in which the electric wire is not connected, whereas the electric wire 200 is inserted to the proper position through the electric wire insertion hole 101 and connected to the terminal plate 10. Then, the connection completion display member 4 that has received a pushing force from the tip of the conductor 201 to the contact portion 42 moves to the connection completion position against the spring force of the coil spring 5 to indicate that the connection of the electric wire 200 has been completed. Will be. In addition, in the present embodiment, the urging portion (coil spring 5) is supported between the support portion 44 provided on the connection completion display member 4 and the terminal plate 10, so that the support portion 43 of the connection completion display member 4 and Compared with the first embodiment in which the coil spring 5 is supported between the container body 100 and the container body 100, there is an advantage that the arrangement space of the connection completion display means in the wire insertion direction can be reduced.

（実施形態３）
本発明の実施形態３を図１０〜図１５を参照して説明する。上述の実施形態１，２では合成樹脂成型品からなる接続完了表示部材４を、別体に形成された付勢部（コイルばね５）により付勢しているのに対して、本実施形態では、弾性を有する板金に抜き加工および曲げ加工を施すことによって表示部と当接部と付勢部とが一体に形成された板ばね部材から接続完了表示部材７を構成している。尚、接続完了表示部材７以外の構成は実施形態１と共通であるので、共通する構成要素には同一の符号を付して適宜図示並びに説明を省略する。 (Embodiment 3)
A third embodiment of the present invention will be described with reference to FIGS. In the first and second embodiments described above, the connection completion display member 4 made of a synthetic resin molded product is urged by the urging portion (coil spring 5) formed separately. The connection completion display member 7 is composed of a leaf spring member in which the display portion, the contact portion, and the urging portion are integrally formed by punching and bending the elastic metal plate. Since the configuration other than the connection completion display member 7 is the same as that of the first embodiment, the same components are denoted by the same reference numerals, and illustration and description thereof are omitted as appropriate.

接続完了表示部材７は、平面視略直角三角形状に形成された主片７０と、主片７０の角部から主片７０の厚み方向に延出された帯状の表示部７１と、主片７０の長辺における両端部より表示部７１と反対向きに曲げ起こされた略Ｓ字状の撓み片７３，７３と、主片７０の長辺における中央部より表示部７１と同じ向きに曲げ起こされた略コ字形の当接部７２とが、弾性を有する板金に抜き加工および曲げ加工を施すことによって一体に形成されてなる。なお、表示部７１の先端部分が略コ字形に折曲されており、この先端部分には合成樹脂のような絶縁材料で箱状に形成されたキャップ（絶縁部材）７４が被せられる。   The connection completion display member 7 includes a main piece 70 formed in a substantially right triangle shape in plan view, a strip-like display portion 71 extending from a corner portion of the main piece 70 in the thickness direction of the main piece 70, and the main piece 70. Are bent in the same direction as the display unit 71 from the central part of the long side of the main piece 70. The substantially U-shaped contact portion 72 is integrally formed by punching and bending an elastic sheet metal. Note that the tip portion of the display unit 71 is bent in a substantially U shape, and a cap (insulating member) 74 formed in a box shape with an insulating material such as synthetic resin is put on the tip portion.

そして、主片１１に設けられた切り欠き孔１１ａに表示部７１を挿通するとともに当接部７２を挿通部１４に挿通するようにして接続完了表示部材７が端子板１０に組み込まれ（図１３参照）、一対の撓み片７３，７３の先端部分が器体１００（カバー１００ｂ）の内壁に当接することで接続完了表示部材７が電線の挿入方向（図１０における上下方向）において移動自在に支持される。すなわち、接続完了表示部材７は撓み片７３，７３のばね力によって常時下方に弾性付勢されており、電線が接続されていない状態では主片７０が端子板１０の主片１１に当接する位置（以下、接続未完了位置という。）で静止し、且つ端子板１０の切り欠き孔１１ａに挿通された表示部７１の先端部分（キャップ７４に覆われた部分）が窓孔１０５を通して器体１００の外に突出することで電線が接続されていない状態を表示している（図１１参照）。   Then, the connection completion display member 7 is incorporated in the terminal board 10 so that the display portion 71 is inserted into the notch hole 11a provided in the main piece 11 and the contact portion 72 is inserted into the insertion portion 14 (FIG. 13). The connection completion display member 7 is supported so as to be movable in the electric wire insertion direction (vertical direction in FIG. 10) by the tip portions of the pair of bending pieces 73, 73 coming into contact with the inner wall of the container 100 (cover 100b). Is done. That is, the connection completion display member 7 is always elastically biased downward by the spring force of the bending pieces 73, 73, and the position where the main piece 70 contacts the main piece 11 of the terminal board 10 when the electric wire is not connected. (Hereinafter, referred to as an incomplete connection position) and the distal end portion (the portion covered by the cap 74) of the display portion 71 inserted through the notch hole 11 a of the terminal board 10 passes through the window hole 105 and the container body 100. The state where the electric wire is not connected is displayed by projecting outside (see FIG. 11).

而して本実施形態においても実施形態１，２と同様に、電線が接続されていない状態では撓み片７３，７３のばね力で接続完了表示部材７が接続未完了位置で静止し、表示部７１の先端部分が窓孔１０５を通して器体１００の外に突出することで電線が接続されていない状態を表示するのに対し（図１４（ａ）参照）、電線２００が電線挿入孔１０１を通して正規の位置まで挿入されて端子板１０と接続されると導体の先端から当接部７２に押し込み力を受けた接続完了表示部材７が、撓み片７３，７３のばね力に抗して接続完了位置まで移動することで電線２００の接続完了が表示されることになる（図１４（ｂ）参照）。しかも、本実施形態では接続完了表示部材７と付勢部（撓み片７３，７３）とが一体に形成されているので、実施形態１，２に比較して部品点数の削減による組立性の向上が図れるものである。   Thus, in the present embodiment as well as in the first and second embodiments, the connection completion display member 7 is stopped at the connection incomplete position by the spring force of the bending pieces 73 and 73 when the electric wire is not connected, and the display unit While the tip of 71 protrudes out of the vessel body 100 through the window hole 105, the state in which the electric wire is not connected is displayed (see FIG. 14A), whereas the electric wire 200 is properly transmitted through the electric wire insertion hole 101. The connection completion display member 7 that has received the pushing force from the tip of the conductor to the contact portion 72 when it is inserted to the position of the terminal plate 10 resists the spring force of the bending pieces 73, 73. The connection completion of the electric wire 200 is displayed by moving to (see FIG. 14B). In addition, in this embodiment, the connection completion display member 7 and the urging portion (flexible pieces 73, 73) are integrally formed, so that the assemblability is improved by reducing the number of parts compared to the first and second embodiments. Can be achieved.

なお、接続完了表示部材７が端子板１０や電線２００などの充電部と接触導通しており、器体１００の外へ露出している表示部７１に直接手が触れると感電事故になる虞があるので、本実施形態では絶縁材料からなるキャップ７４で表示部４１の先端部分を覆うことで金属製の表示部７１に直接手が触れないようにして感電事故を防いでいる。但し、図１５に示すように表示部７１と同時成形された合成樹脂成形品からなる絶縁部材７４’で表示部７１を覆うようにすれば、キャップ７４を表示部７１に装着する手間が省けて組立性が向上するという利点がある。   Note that the connection completion display member 7 is in contact with the charging unit such as the terminal board 10 and the electric wire 200, and if the hand touches the display unit 71 exposed to the outside of the body 100, there is a risk of an electric shock. Therefore, in this embodiment, the cap 74 made of an insulating material covers the tip portion of the display unit 41 so that the metal display unit 71 is not directly touched by hands to prevent an electric shock accident. However, as shown in FIG. 15, if the display unit 71 is covered with an insulating member 74 ′ made of a synthetic resin molded product that is simultaneously molded with the display unit 71, the trouble of attaching the cap 74 to the display unit 71 can be saved. There is an advantage that the assemblability is improved.

（実施形態４）
図１６〜図２１を参照して本発明の実施形態４を説明する。但し、本実施形態の基本構成は実施形態３と共通であるから、共通の構成要素には同一の符号を付して適宜図示並びに説明を省略する。 (Embodiment 4)
A fourth embodiment of the present invention will be described with reference to FIGS. However, since the basic configuration of the present embodiment is the same as that of the third embodiment, the same components are denoted by the same reference numerals, and illustration and description thereof are omitted as appropriate.

実施形態３においては複数の速結端子装置毎に接続完了表示部材７が設けられているが、本実施形態は、隣接して配設された２つの速結端子装置の接続完了表示部材を一体に構成した点に特徴がある。   In the third embodiment, the connection completion display member 7 is provided for each of the plurality of quick connection terminal devices. However, in this embodiment, the connection completion display members of two adjacent quick connection terminal devices are integrated. It is characterized in that it is configured as follows.

本実施形態における接続完了表示部材８は、一対の短冊状の主片８０，８０と、各主片８０，８０の長手方向一端部から主片８０，８０の厚み方向に延出された帯状の表示部８１，８１と、各主片８０，８０の長手方向他端部から表示部８１，８１と同じ向きに曲げ起こされた略コ字状の当接部８２，８２と、各主片８０，８０において短手方向に当接部８２，８２と向き合う形で表示部８１，８１と反対向きに曲げ起こされた略Ｓ字状の撓み片８３，８３と、一対の撓み片８３，８３の先端同士を繋ぐ帯状の橋架片８４とが、弾性を有する板金に抜き加工および曲げ加工を施すことによって一体に形成されてなる。なお、表示部８１，８１の先端部分が略コ字形に折曲されており、実施形態３と同様に、この先端部分には合成樹脂のような絶縁材料で箱状に形成されたキャップ（絶縁部材）８５，８５が被せられる。   The connection completion display member 8 in the present embodiment has a pair of strip-shaped main pieces 80, 80 and strip-like shapes extending from the longitudinal ends of the main pieces 80, 80 in the thickness direction of the main pieces 80, 80. Display portions 81, 81, substantially U-shaped contact portions 82, 82 bent up in the same direction as the display portions 81, 81 from the other longitudinal end of each main piece 80, 80, and each main piece 80 80, substantially S-shaped bending pieces 83, 83 bent in the opposite direction to the display portions 81, 81 in a shape facing the contact portions 82, 82 in the short direction, and a pair of bending pieces 83, 83 A band-shaped bridge piece 84 that connects the tips is integrally formed by punching and bending an elastic sheet metal. Note that the tip portions of the display portions 81 and 81 are bent in a substantially U-shape, and as in the third embodiment, the tip portion is a cap (insulating) formed of an insulating material such as a synthetic resin. Members) 85, 85.

そして、主片１１に設けられた一対の切り欠き孔１１ａ，１１ａにそれぞれ表示部８１，８１を挿通するとともに当接部８２，８２を各挿通部１４，１４に挿通するようにして接続完了表示部材８が端子板１０に組み込まれ（図１６参照）、一対の撓み片８３，８３を繋ぐ橋架片８４が器体１００（カバー１００ｂ）の内壁に当接することで接続完了表示部材８が電線の挿入方向（図１６における上下方向）において移動自在に支持される。すなわち、接続完了表示部材８は撓み片８３，８３のばね力によって常時下方に弾性付勢されており、電線が接続されていない状態では主片８０が端子板１０の主片１１に当接する接続未完了位置で静止し、且つ端子板１０の切り欠き孔１１ａ，１１ａに挿通された表示部８１，８１の先端部分（キャップ８５，８５に覆われた部分）が各々窓孔１０５，１０５を通して器体１００の外に突出することで電線が接続されていない状態を表示する。   Then, the display unit 81 and 81 are inserted into the pair of cutout holes 11a and 11a provided in the main piece 11, respectively, and the contact portions 82 and 82 are inserted into the insertion portions 14 and 14, respectively. The member 8 is incorporated into the terminal board 10 (see FIG. 16), and the bridge piece 84 connecting the pair of flexure pieces 83, 83 abuts against the inner wall of the vessel body 100 (cover 100b), so that the connection completion indication member 8 is connected to the electric wire. It is supported movably in the insertion direction (vertical direction in FIG. 16). That is, the connection completion display member 8 is always elastically biased downward by the spring force of the bending pieces 83, 83 so that the main piece 80 contacts the main piece 11 of the terminal board 10 when no electric wire is connected. The tip portions (the portions covered by the caps 85 and 85) of the display portions 81 and 81 inserted into the notch holes 11a and 11a of the terminal board 10 are stopped at the unfinished positions, respectively, through the window holes 105 and 105, respectively. The state where the electric wire is not connected is displayed by projecting out of the body 100.

而して本実施形態においても実施形態３と同様に、電線が接続されていない状態では撓み片８３，８３のばね力で接続完了表示部材７が接続未完了位置で静止し、表示部８１，８１の先端部分が窓孔１０５，１０５を通して器体１００の外に突出することで電線が接続されていない状態を表示するのに対し、電線２００が電線挿入孔１０１を通して正規の位置まで挿入されて端子板１０と接続されると導体の先端から当接部８２に押し込み力を受けた接続完了表示部材８が、撓み片８３，８３のばね力に抗して接続完了位置まで移動することで電線２００の接続完了が表示されることになる。しかも、本実施形態では隣接して配設された２つの速結端子装置の接続完了表示部材を一体に構成しているため、実施形態３に比較して部品点数の削減による組立性の向上が図れる。   Thus, in the present embodiment as well as in the third embodiment, in a state where the electric wires are not connected, the connection completion display member 7 is stopped at the connection incomplete position by the spring force of the bending pieces 83, 83, and the display unit 81, The tip portion of 81 protrudes out of the vessel body 100 through the window holes 105 and 105 to indicate a state in which the electric wire is not connected, whereas the electric wire 200 is inserted to the proper position through the electric wire insertion hole 101. When connected to the terminal board 10, the connection completion display member 8 that has received a pressing force from the tip of the conductor to the contact portion 82 moves to the connection completion position against the spring force of the bending pieces 83, 83. 200 connection completion is displayed. In addition, in this embodiment, since the connection completion display members of the two quick connection terminal devices arranged adjacent to each other are integrally formed, the assembly performance is improved by reducing the number of parts compared to the third embodiment. I can plan.

ここで、図１８の展開図に示すように、本実施形態における接続完了表示部材８では電線２００から押し込み力を受ける当接部８２，８２と、付勢部たる撓み片８３，８３とが電線２００の挿入方向に沿って一列に配置されるように形成されているので、電線２００から当接部８２に押し込み力を受けた場合に撓み片８３，８３に歪みが生じにくくなり、その結果、表示部８１，８１（接続完了表示部材８）を安定して移動させることができる。   Here, as shown in the development view of FIG. 18, in the connection completion display member 8 in the present embodiment, the contact portions 82 and 82 that receive the pushing force from the electric wire 200 and the flexure pieces 83 and 83 that are the urging portions are the electric wires. 200 is formed so as to be arranged in a line along the insertion direction of 200, so that when the pressing force is applied to the contact portion 82 from the electric wire 200, the bending pieces 83 and 83 are less likely to be distorted. The display parts 81 and 81 (connection completion display member 8) can be moved stably.

ところで、図１８の展開図からも明らかなように、当接部８２，８２と撓み片８３，８３とが一列に配置されるような形状に接続完了表示部材８を形成した場合、板材から接続完了表示部材８の板ばね部材を抜き取る際に無駄になる部分が増えて効率よく抜き取ることができない、所謂、板取りが悪くなるという欠点がある。   As is apparent from the developed view of FIG. 18, when the connection completion display member 8 is formed in such a shape that the contact portions 82 and 82 and the flexure pieces 83 and 83 are arranged in a line, the connection is made from the plate material. When the leaf spring member of the completion display member 8 is pulled out, there is a disadvantage that the portion that is wasted increases and cannot be removed efficiently.

そこで、図１９〜図２１に示すように、表示部８１，８１、当接部８２，８２、撓み片８３，８３が全て主片８０の長手方向に沿った一端縁から延出される形状、すなわち、当接部８２と撓み片８３とが電線２００の挿入方向に沿ってずれて配置されるような形状に接続完了表示部材８を形成すれば、図１８と図２１から明らかなように接続完了表示部材８の板ばね部材を効率よく抜き取ることができて板取りがよくなるという利点がある。   Accordingly, as shown in FIGS. 19 to 21, the display portions 81 and 81, the contact portions 82 and 82, and the bending pieces 83 and 83 are all extended from one end edge along the longitudinal direction of the main piece 80, that is, If the connection completion display member 8 is formed in such a shape that the abutting portion 82 and the flexure piece 83 are displaced along the insertion direction of the electric wire 200, the connection is completed as is apparent from FIGS. There is an advantage that the plate spring member of the display member 8 can be efficiently extracted and the plate removal is improved.

（実施形態５）
図２２〜図２５を参照して本発明の実施形態５を説明する。但し、本実施形態は接続完了表示手段に特徴があり、その他の構成は実施形態１〜４と共通であるから、共通の構成要素には同一の符号を付して適宜図示並びに説明を省略する。 (Embodiment 5)
A fifth embodiment of the present invention will be described with reference to FIGS. However, the present embodiment is characterized by the connection completion display means, and the other configurations are the same as those of the first to fourth embodiments. Therefore, the same reference numerals are given to common components, and illustration and description are omitted as appropriate. .

これまで説明した実施形態１〜４では、全て接続完了表示部材４，７，８の移動方向が電線２００の挿入方向と平行であり、表示部４１，７１，８１は何れも器体１００の底面（電線挿入孔１０１が開口する面）に設けられた窓孔１０５を通して器体１００の外に突出する構成であった。これに対して本実施形態では、電線２００の挿入方向に対して交差する方向（例えば、直交する方向）に接続完了表示部材９が移動し、器体１００の側面に設けられた窓孔１０６を通して表示部９１が器体１００の外に突出する構成とした点に特徴がある。   In the first to fourth embodiments described so far, the movement directions of the connection completion display members 4, 7, 8 are all parallel to the insertion direction of the electric wire 200, and the display units 41, 71, 81 are all bottom surfaces of the container body 100. It was the structure which protrudes out of the container 100 through the window hole 105 provided in (the surface which the electric wire insertion hole 101 opens). On the other hand, in this embodiment, the connection completion display member 9 moves in a direction intersecting the insertion direction of the electric wire 200 (for example, a direction orthogonal), and passes through the window hole 106 provided on the side surface of the vessel body 100. The display unit 91 is characterized in that it protrudes out of the body 100.

本実施形態における接続完了表示部材９は合成樹脂成形品からなり、図２４に示すように五角柱形状の主部９０と、主部９０の一面から法線方向に突出する丸棒状の表示部９１とが一体に形成されている。主部９０は、１つの頂点を含む三角柱の部分が切り取られた形状に形成されており、当該切り取られた後に残った部分に、表示部９１が突出する面から隣の面にかけて形成されている傾斜面が当接部９２となる。   The connection completion display member 9 in the present embodiment is made of a synthetic resin molded product, and as shown in FIG. 24, a pentagonal columnar main portion 90 and a round bar-shaped display portion 91 protruding in the normal direction from one surface of the main portion 90. And are integrally formed. The main portion 90 is formed in a shape in which a triangular prism portion including one vertex is cut out, and is formed from the surface from which the display portion 91 protrudes to the adjacent surface in the portion remaining after the cutting. The inclined surface becomes the contact portion 92.

一方、本実施形態における付勢部９３は略コ字形に形成された板ばねからなり、端子板１０の当接片１３，１３にかしめ固定される帯状の固定片９３ａと、固定片９３ａと長手方向両端より各々同一向きに略へ字形に曲げ起こされた一対の撓み片９３ｂ，９３ｂとを有する。但し、板ばねの代わりにコイルばねで付勢部９３を構成しても構わない。   On the other hand, the urging portion 93 in the present embodiment is formed of a substantially U-shaped leaf spring, and is fixed to the contact pieces 13 and 13 of the terminal plate 10 by caulking, a fixing piece 93a and a longitudinal direction. It has a pair of bending pieces 93b and 93b bent up substantially in a U-shape in the same direction from both ends in the direction. However, the urging portion 93 may be configured by a coil spring instead of the leaf spring.

そして、図２５に示すように２つの接続完了表示部材９，９が端子板１０の主片１１上に載置され、カバー１００ｂの側面に設けられた一対の溝からなる窓孔１０６，１０６に接続完了表示部材９，９の表示部９１，９１がそれぞれ進退自在に挿入される。また、固定片９３ａが当接片１３，１３にかしめ固定されることで付勢部９３が端子板１０に取り付けられ、付勢部９３の撓み片９３ｂ，９３ｂが接続完了表示部材９，９の主部９０，９０に各々当接することで表示部９１，９１が窓孔１０６，１０６から器体１００の外へ突出する向きに接続完了表示部材９，９が付勢される（図２５（ａ）参照）。すなわち、接続完了表示部材９は付勢部９３のばね力によって常時側方（図２５における左向き）に弾性付勢されており、電線２００が接続されていない状態では主部９０がカバー１００ｂの内壁面に当接し且つ器体１００の側面に設けられた窓孔１０６を通して表示部９１の先端部分が器体１００の外へ突出する位置（接続未完了位置）で静止しており、このように表示部９１の先端部分が窓孔１０６を通して器体１００外へ突出することで電線２００が接続されていない状態を表示している（図２３参照）。   Then, as shown in FIG. 25, two connection completion display members 9, 9 are placed on the main piece 11 of the terminal board 10, and are inserted into the window holes 106, 106 formed of a pair of grooves provided on the side surface of the cover 100b. The display portions 91 and 91 of the connection completion display members 9 and 9 are inserted so as to freely advance and retract, respectively. Further, the urging portion 93 is attached to the terminal board 10 by the caulking and fixing of the fixing piece 93 a to the contact pieces 13 and 13, and the bending pieces 93 b and 93 b of the urging portion 93 are connected to the connection completion display members 9 and 9. The contact completion display members 9 and 9 are urged in such a direction that the display portions 91 and 91 protrude from the window holes 106 and 106 to the outside of the container body 100 by contacting the main portions 90 and 90, respectively (FIG. 25A )reference). That is, the connection completion display member 9 is always elastically biased sideways (leftward in FIG. 25) by the spring force of the biasing portion 93, and the main portion 90 is within the cover 100b in a state where the electric wire 200 is not connected. The tip of the display unit 91 is stationary at a position where the tip of the display unit 91 protrudes out of the container 100 (a connection incomplete position) through the window hole 106 provided on the side surface of the container 100 in contact with the wall surface. The state where the electric wire 200 is not connected is displayed by the tip portion of the portion 91 projecting out of the body 100 through the window hole 106 (see FIG. 23).

そして、器体１００の電線挿入孔１０１を通して電線２００の導体２０１を正規の位置まで挿入すると、導体２０１が錠ばね２０と端子板１０の接触片１２との間で狭持されて接続されるとともに、図２５（ｂ）に示すように導体２０１の先端が挿通部１４を通して接続完了表示表示部材９の当接部９２に当たり、当接部９２を側方（図２５における右向き）に押圧する。このとき当接部９２が導体２０１の押し込み力を受け、付勢部９３のばね力に抗して接続完了表示表示部材９が右向きに移動する。その結果、接続完了表示表示部材９の表示部９１が窓孔１０６内に退避する接続完了位置まで移動して電線２００が端子板１０と接続されたこと（接続完了）が表示される。   And if the conductor 201 of the electric wire 200 is inserted to a regular position through the electric wire insertion hole 101 of the vessel body 100, the conductor 201 is sandwiched and connected between the lock spring 20 and the contact piece 12 of the terminal plate 10. As shown in FIG. 25 (b), the tip of the conductor 201 hits the contact portion 92 of the connection completion display display member 9 through the insertion portion 14, and presses the contact portion 92 to the side (rightward in FIG. 25). At this time, the contact portion 92 receives the pushing force of the conductor 201, and the connection completion display display member 9 moves rightward against the spring force of the biasing portion 93. As a result, the display unit 91 of the connection completion display display member 9 moves to the connection completion position where it is retracted into the window hole 106, and it is displayed that the electric wire 200 is connected to the terminal board 10 (connection completion).

一方、解除レバー６の操作部６３を操作して電線２００が引き抜かれると、接続完了表示表示部材９の当接部９２を右向きに押圧する力が無くなるから、付勢部９３のばね力によって接続完了表示表示部材９が接続未完了位置に移動し、表示部９１の先端部分が窓孔１０６から器体１００の外へ突出することで接続未完了状態が表示される。   On the other hand, when the operation part 63 of the release lever 6 is operated and the electric wire 200 is pulled out, there is no force to push the contact part 92 of the connection completion display display member 9 rightward. The completion display display member 9 moves to the connection incomplete position, and the distal end portion of the display unit 91 projects out of the body 100 from the window hole 106, so that the connection incomplete state is displayed.

このように本実施形態においても実施形態１〜４と同様に、端子板１０と電線２００との接続が完了すると、接続完了表示部材９の表示部９１が器体１００の窓孔１０６内に退避する位置（接続完了位置）に移動するから、表示部９１が窓孔１０６から器体１００の外へ突出しているか否かで電線２００の接続完了表示を視覚的に確認することができ、しかも、解除レバー６を操作して電線２００を電線挿入孔１０１から引き抜くと付勢部９３に付勢されている接続完了表示部材９が接続完了位置から接続未完了位置へ自動的に復帰するため、従来例のように電線２００の接続を解除した後に何ら操作をすること無しに電線２００を再度接続する際に接続完了状態を表示することができる。   As described above, in this embodiment as well as in the first to fourth embodiments, when the connection between the terminal plate 10 and the electric wire 200 is completed, the display portion 91 of the connection completion display member 9 is retracted into the window hole 106 of the container 100. Since it moves to the position to be connected (connection completion position), the connection completion display of the electric wire 200 can be visually confirmed by whether or not the display part 91 protrudes out of the body 100 from the window hole 106, When the release lever 6 is operated to pull out the electric wire 200 from the electric wire insertion hole 101, the connection completion display member 9 urged by the urging portion 93 automatically returns from the connection completion position to the connection incomplete position. The connection completion state can be displayed when reconnecting the electric wire 200 without performing any operation after releasing the connection of the electric wire 200 as in the example.

なお、実施形態１〜４のように電線２００の接続完了表示用の窓孔１０５が器体１００における電線挿入孔１０１と同一面に設けられている場合と比較して、本実施形態のように器体１００における電線挿入孔１０１と異なる面に窓孔１０６を設けて接続完了表示を行う方が、表示部９１による接続完了表示が視認しやすいという利点がある。   In addition, compared with the case where the window hole 105 for the connection completion display of the electric wire 200 is provided on the same surface as the electric wire insertion hole 101 in the container body 100 as in the first to fourth embodiments, as in the present embodiment. There is an advantage that the connection completion display by the display unit 91 is easily visible when the window hole 106 is provided on a surface different from the wire insertion hole 101 in the container 100 and the connection completion display is performed.

（実施形態６）
図２６〜図２９を参照して本発明の実施形態６を説明する。但し、本実施形態は接続完了表示手段に特徴があり、その他の構成は実施形態５と共通であるから、共通の構成要素には同一の符号を付して適宜図示並びに説明を省略する。 (Embodiment 6)
A sixth embodiment of the present invention will be described with reference to FIGS. However, this embodiment is characterized by the connection completion display means, and the other configurations are the same as those of the fifth embodiment. Therefore, the same components are denoted by the same reference numerals, and illustration and description thereof are omitted as appropriate.

実施形態５では合成樹脂成形品からなる接続完了表示部材９と、板ばね部材からなる付勢部９３とで接続完了表示手段を構成しているのに対し、本実施形態では、付勢部も合成樹脂成形品として接続完了表示部材と一体に構成した点に特徴がある。   In the fifth embodiment, the connection completion display member 9 made of a synthetic resin molded product and the urging portion 93 made of a leaf spring member constitute a connection completion display means, whereas in this embodiment, the urging portion also The synthetic resin molded product is characterized in that it is integrally formed with the connection completion display member.

本実施形態における接続完了表示部材１１０は、図２７に示すように円柱状の主部１１１と、主部１１１の周面より径方向に突出した略丁字状の付勢部１１２と、付勢部１１２の両端に設けられた略六角柱状の当接部１１３，１１３と、各当接部１１３，１１３より突出する円柱状の表示部１１４，１１４とを具備した合成樹脂成形品からなる。主部１１１の一端面には略Ｃ字形の嵌合溝（固定部）１１１ａが形成されており、端子板１０の主片１１中央に突設されている円柱状の嵌合突起１１ｂを嵌合溝１１１ａに嵌合することで接続完了表示部材１１０が端子板１０に固定されるようになっている（図２８参照）。また、一対の当接部１１３，１１３は、主部１１１が端子板１０に固定された状態で端子板１０の挿通部１４，１４と対向する面が電線２００の挿入方向に対して傾斜する傾斜面１１３ａ，１１３ａとなっている。   As shown in FIG. 27, the connection completion display member 110 in the present embodiment includes a columnar main portion 111, an approximately letter-like biasing portion 112 projecting in a radial direction from the peripheral surface of the main portion 111, and a biasing portion. 112 is formed of a synthetic resin molded article having substantially hexagonal column-shaped contact portions 113 and 113 provided at both ends of 112 and columnar display portions 114 and 114 protruding from the contact portions 113 and 113. A substantially C-shaped fitting groove (fixed portion) 111 a is formed on one end surface of the main portion 111, and a columnar fitting protrusion 11 b protruding from the center of the main piece 11 of the terminal board 10 is fitted. The connection completion display member 110 is fixed to the terminal board 10 by fitting into the groove 111a (see FIG. 28). In addition, the pair of contact portions 113 and 113 are inclined such that the surfaces facing the insertion portions 14 and 14 of the terminal plate 10 are inclined with respect to the insertion direction of the electric wire 200 in a state where the main portion 111 is fixed to the terminal plate 10. Surfaces 113a and 113a are formed.

ここで、電線２００が接続されていない状態では各表示部１１４，１１４の先端部分が器体１００の側面に設けられた窓孔１０６，１０６内に退避した位置（接続未完了位置）にあり（図２６（ａ）参照）、このように表示部１１４，１１４の先端部分が窓孔１０６，１０６から突出しないことで電線２００が接続されていない状態を表示している。   Here, in the state where the electric wire 200 is not connected, the tip portions of the display portions 114 and 114 are in the positions retracted into the window holes 106 and 106 provided on the side surfaces of the container body 100 (connection incomplete positions) ( As shown in FIG. 26A, the state where the electric wire 200 is not connected is displayed because the tip portions of the display portions 114 and 114 do not protrude from the window holes 106 and 106 as described above.

そして、器体１００の電線挿入孔１０１を通して電線２００の導体２０１を正規の位置まで挿入すると、導体２０１が錠ばね２０と端子板１０の接触片１２との間で狭持されて接続されるとともに、図２６（ｂ）に示すように導体２０１の先端が挿通部１４を通して接続完了表示表示部材１１０の当接部１１３（傾斜面）に当たり、当接部１１３を側方（図２６における左向き）に押圧する。このとき当接部１１３が導体２０１の押し込み力を受け、付勢部１１２のばね力に抗して当接部１１３並びに表示部１１４が左向きに移動する。その結果、表示部１１４が窓孔１０６から器体１００の外へ突出する位置（接続完了位置）まで移動して電線２００が端子板１０と接続されたこと（接続完了）が表示される。   And if the conductor 201 of the electric wire 200 is inserted to a regular position through the electric wire insertion hole 101 of the vessel body 100, the conductor 201 is sandwiched and connected between the lock spring 20 and the contact piece 12 of the terminal plate 10. As shown in FIG. 26B, the tip of the conductor 201 hits the contact portion 113 (inclined surface) of the connection completion display display member 110 through the insertion portion 14, and the contact portion 113 is set to the side (leftward in FIG. 26). Press. At this time, the contact portion 113 receives the pushing force of the conductor 201, and the contact portion 113 and the display portion 114 move to the left against the spring force of the biasing portion 112. As a result, it is displayed that the display unit 114 has moved from the window hole 106 to the position protruding from the container body 100 (connection completion position) and the electric wire 200 is connected to the terminal board 10 (connection completion).

一方、解除レバー６の操作部６３を操作して電線２００が引き抜かれると、当接部１１３を左向きに押圧する力が無くなるから、付勢部１１２のばね力によって当接部１１３並びに表示部１１４が接続未完了位置に移動し、表示部１１４の先端部分が窓孔１０６内に退避することで接続未完了状態が表示される。   On the other hand, when the operation part 63 of the release lever 6 is operated and the electric wire 200 is pulled out, the force that presses the contact part 113 to the left disappears, so the contact part 113 and the display part 114 are pressed by the spring force of the biasing part 112. Is moved to the connection incomplete position, and the tip end portion of the display unit 114 is retracted into the window hole 106 to display the connection incomplete state.

このように本実施形態においては、端子板１０と電線２００との接続が完了すると、接続完了表示部材１１０の表示部１１４が窓孔１０６から器体１００の外へ突出する位置（接続完了位置）に移動するから、表示部１１４が窓孔１０６から器体１００の外へ突出しているか否かで電線２００の接続完了表示を視覚的に確認することができ、しかも、解除レバー６を操作して電線２００を電線挿入孔１０１から引き抜くと付勢部１１２に付勢されている表示部１１４が接続完了位置から接続未完了位置へ自動的に復帰するため、従来例のように電線２００の接続を解除した後に何ら操作をすること無しに電線２００を再度接続する際に接続完了状態を表示することができる。   Thus, in this embodiment, when the connection between the terminal plate 10 and the electric wire 200 is completed, the position where the display portion 114 of the connection completion display member 110 protrudes out of the container body 100 from the window hole 106 (connection completion position). Therefore, it is possible to visually confirm the connection completion indication of the electric wire 200 based on whether or not the display portion 114 protrudes out of the body 100 from the window hole 106, and the release lever 6 is operated. When the electric wire 200 is pulled out from the electric wire insertion hole 101, the display unit 114 urged by the urging unit 112 automatically returns from the connection completion position to the connection incomplete position. The connection completion state can be displayed when the electric wire 200 is connected again without any operation after the release.

ところで、接続完了表示部材１１０においては付勢部１１２が中央部分を支点として撓む構造であるから、表示部１１４は実施形態１〜５のように平行移動するのではなく円弧上を移動することになる。そのため、接続完了位置にある表示部１１４の軸方向が器体１００側面の法線方向に対して傾くことになる。そこで本実施形態では、この傾きに対応して表示部材１１０の先端面をその軸方向に対して傾斜させ、接続完了位置において表示部１１４の先端面と器体１００側面とが略平行となるようにして接続完了位置における表示部１１４の視認性を向上している（図２９参照）。   By the way, in the connection completion display member 110, since the urging | biasing part 112 is a structure bent with a center part as a fulcrum, the display part 114 does not move in parallel like Embodiment 1-5, but moves on a circular arc. become. Therefore, the axial direction of the display unit 114 at the connection completion position is inclined with respect to the normal direction of the side surface of the body 100. Therefore, in the present embodiment, the front end surface of the display member 110 is inclined with respect to the axial direction corresponding to this inclination, and the front end surface of the display unit 114 and the side surface of the body 100 are substantially parallel at the connection completion position. Thus, the visibility of the display unit 114 at the connection completion position is improved (see FIG. 29).
