When the body 107 is stored in the storage chamber 104, the step portion 253 c is inserted into the terminal plate 24 notch groove 24 a, so that the portion on the left side of the step portion 253 ca of the contact piece 253 is the base of the terminal plate 24. It is supported from below by the piece 242.

上述のように構成される端子板２４と鎖錠ばね２５は、図４に示すようにボディ１０７の収納室１０４内に収納される。そして、図７に示すように、電線挿入孔１０７ｂを通して外部から収納室１０４内に電線３０が挿入されると、電線３０の先端で押された鎖錠片２５２が接触片２４１ａから離れる向き（下向き）に撓み、鎖錠片２５２が撓むにつれて電線３０が更に挿し込まれる。そして、電線３０が所定の位置まで挿入されると、鎖錠片２５２の先端が電線３０に当接して反挿入向き（後ろ向き）に抜け止めされる。更に、鎖錠ばね２５の復元力（ばね力）により鎖錠片２５２が電線３０を接触片２４１ａの接触面（下面）に弾接させて電線３０と接触片２４１ａを接触導通させることが出来る。   The terminal plate 24 and the lock spring 25 configured as described above are housed in the housing chamber 104 of the body 107 as shown in FIG. Then, as shown in FIG. 7, when the electric wire 30 is inserted into the storage chamber 104 from the outside through the electric wire insertion hole 107b, the locking piece 252 pushed at the tip of the electric wire 30 is separated from the contact piece 241a (downward). ) And the wire 30 is further inserted as the locking piece 252 is bent. And if the electric wire 30 is inserted to a predetermined position, the front-end | tip of the locking piece 252 will contact | abut to the electric wire 30, and will be prevented from coming off in the anti-insertion direction (backward direction). Furthermore, the locking piece 252 can elastically contact the electric wire 30 with the contact surface (lower surface) of the contact piece 241a by the restoring force (spring force) of the lock spring 25, and the electric wire 30 and the contact piece 241a can be brought into contact with each other.

ここで、本実施形態の端子装置４０では、電線３０の接続時において、電線３０が鎖錠片２５２に当たると、当接片２５３を支点として鎖錠片２５２が接触片２４１ａから離れる向き（図７における時計回り）に鎖錠ばね２５が回転する。そのため、電線３０の挿入時に鎖錠片２５２が電線３０側に巻き込まれることがなく、電線３０と端子板２４との接触信頼性を向上することができる。   Here, in the terminal device 40 of this embodiment, when the electric wire 30 is connected, when the electric wire 30 hits the locking piece 252, the locking piece 252 is separated from the contact piece 241 a with the contact piece 253 as a fulcrum (FIG. 7). The lock spring 25 rotates clockwise. Therefore, the locking piece 252 is not wound around the electric wire 30 when the electric wire 30 is inserted, and the contact reliability between the electric wire 30 and the terminal plate 24 can be improved.

また、一対の囲み片２４１ｃが接触片２４１ａに設けられていることにより、電線３０が単線であれば左右方向における電線３０の移動範囲を囲み片２４１ｃで規制することができる。さらに、電線３０が撚り線であれば素線のばらける範囲を囲み片２４１ｃで規制することができるので、電線３０と端子板２４との接触信頼性がさらに向上するという利点がある。しかも本実施形態では、囲み片２４１ｃの先端部分が、囲み片２４１ｂ側へ突出する形状に形成しているため、電線３０の移動範囲やばらける範囲をより確実に規制することができる。さらに、端子板２４に囲み片２４１ｂが設けられているため、接触片２４１ａから離れる向きの電線３０の移動を規制することができる。   In addition, by providing the pair of surrounding pieces 241c on the contact piece 241a, if the electric wire 30 is a single wire, the movement range of the electric wire 30 in the left-right direction can be restricted by the surrounding piece 241c. Furthermore, if the electric wire 30 is a stranded wire, the range in which the strands can be separated can be regulated by the surrounding piece 241c, so that the contact reliability between the electric wire 30 and the terminal plate 24 is further improved. In addition, in the present embodiment, the distal end portion of the surrounding piece 241c is formed in a shape that protrudes toward the surrounding piece 241b, so that the moving range and the range of the electric wire 30 can be more reliably regulated. Furthermore, since the surrounding piece 241b is provided in the terminal board 24, the movement of the electric wire 30 in the direction away from the contact piece 241a can be restricted.

また本実施形態の端子装置４０では、端子板２４の接触片２４１ａが電線３０との当接方向（上下方向）において可撓性を有している。そのため、電線挿入孔１０７ｂに対して電線３０が傾いた場合においても接触片２４１ａが電線３０の動きに追従して常に安定した接触状態を確保することができる。さらに、撚り線からなる電線３０が、ばらけている場合や径の小さい（細い）電線３０であっても接触片２４１ａと鎖錠片２５２とで電線３０を弾性挟持することにより、端子板２４と鎖錠ばね２５との接触状態を安定させることができる。尚、接触片２４１ａが撓む範囲はボディ１０７における収納室１０４の内壁によって規制されているので、電線３０が傾いたりした場合であっても接触片２４１ａの塑性変形が防止できるものである。   Moreover, in the terminal device 40 of this embodiment, the contact piece 241a of the terminal plate 24 has flexibility in the contact direction (vertical direction) with the electric wire 30. Therefore, even when the electric wire 30 is inclined with respect to the electric wire insertion hole 107b, the contact piece 241a can follow the movement of the electric wire 30 and always ensure a stable contact state. Furthermore, even if the electric wire 30 made of a stranded wire is scattered or has a small diameter (thin), the terminal plate 24 can be elastically sandwiched between the contact piece 241a and the locking piece 252. And the locking spring 25 can be stabilized. In addition, since the range in which the contact piece 241a bends is regulated by the inner wall of the storage chamber 104 in the body 107, the plastic deformation of the contact piece 241a can be prevented even when the electric wire 30 is tilted.

次に解除レバー２６について説明する。解除レバー２６は合成樹脂成型品からなり、半円板状の支持部２６１と、矩形平板状の操作部２６２と、支持部２６１及び操作部２６２を連結する略三角形板状の連結部２６３とを有して全体が略コ字形に形成されている。   Next, the release lever 26 will be described. The release lever 26 is formed of a synthetic resin molded product, and includes a semicircular plate-like support portion 261, a rectangular flat plate-like operation portion 262, and a substantially triangular plate-like connection portion 263 that connects the support portion 261 and the operation portion 262. And has a substantially U-shape as a whole.

また、一対の連結部２６３にはそれぞれ押動部２６４が突設されている。押動部２６４は扁平な略三角柱状に形成され、後述するように鎖錠片２５２と対向する側の斜面で鎖錠片２５２に接離自在に当接するとともに、当該斜面と反対側の角部で接触片２４１ａに接離自在に当接する。また、解除レバー２６は、その操作部２６２が器体１０６における検電孔１０７ｃから外部に露出し、当該検電孔１０７ｃ内に移動自在に設けられる。ここで、操作部２６２の可動範囲は、検電孔１０７ｃ内に設定される。そして、解除レバー２６は、一対の連結部２６３間に接触片２４１ａと鎖錠ばね２５が配置されるようにしてボディ１０７の収納室１０４内に収納される。ここで、収納室１０４内には半円弧状の摺動面を有した軸受け台１０５が設けられており（図７参照）、収納室１０４内に収納された解除レバー２６の支持部２６１が軸受け台１０５に載置されることにより、支持部２６１を支点として解除レバー２６が回動自在にボディ１０７に支持される。   The pair of connecting portions 263 are respectively provided with pushing portions 264. The pushing portion 264 is formed in a flat and substantially triangular prism shape, and comes into contact with and separates from the locking piece 252 on the inclined surface facing the locking piece 252 as will be described later, and the corner on the opposite side to the inclined surface. Thus, the contact piece 241a abuts on and away from the contact piece 241a. Further, the release lever 26 is provided so that its operation portion 262 is exposed to the outside from the voltage detection hole 107 c in the device body 106 and is movable in the voltage detection hole 107 c. Here, the movable range of the operation unit 262 is set in the detection hole 107c. The release lever 26 is stored in the storage chamber 104 of the body 107 such that the contact piece 241a and the lock spring 25 are disposed between the pair of connecting portions 263. Here, a bearing base 105 having a semicircular arc-shaped sliding surface is provided in the storage chamber 104 (see FIG. 7), and the support portion 261 of the release lever 26 stored in the storage chamber 104 is a bearing. By being placed on the base 105, the release lever 26 is rotatably supported by the body 107 with the support portion 261 as a fulcrum.

而して、端子装置４０に接続された電線３０を取り外すには、図７に示すように、検電孔１０７ｃを通して器体１０６の上面側に露出している操作部２６２を指で押し上げるように操作すればよい。すなわち、操作部２６２を検電孔１０７ｃ内で上方へ押し上げるように操作すれば、支持部２６１を支点にして解除レバー２６が時計回りに回動し、初めに押動部２６４の上側の角部がそれぞれ接触片２４１ａの先端部を電線３０から離れる向き（上向き）に変位させる。解除レバー２６が時計回りにさらに回動すると、今度は押動部２６４が鎖錠片２５２を下方へ押圧することにより、電線３０に当接している鎖錠片２５２を電線３０から離す向きに変位させて電線３０の取り外しが可能となる。   Thus, in order to remove the electric wire 30 connected to the terminal device 40, as shown in FIG. 7, the operation part 262 exposed on the upper surface side of the device body 106 is pushed up with a finger through the detection hole 107c. Just operate. That is, if the operation unit 262 is operated to be pushed upward in the detection hole 107c, the release lever 26 is rotated clockwise with the support unit 261 as a fulcrum, and the corner portion on the upper side of the push unit 264 first. Are displaced in the direction away from the electric wire 30 (upward), respectively. When the release lever 26 is further rotated clockwise, this time, the pushing portion 264 presses the locking piece 252 downward, so that the locking piece 252 that is in contact with the electric wire 30 is displaced away from the electric wire 30. Thus, the electric wire 30 can be removed.

上記構成からなる本実施形態の配線器具では、検電孔１０７ｃを介して、端子装置（鎖錠ばね２５の折曲片２５３ｂ）４０の一部が、ボディ１０７の上面より外部に露出している。ここで、上述の通り、端子板２４及び鎖錠ばね２５は、共に導電性材料から形成されていることから、検電孔１０７ｃより検電ドライバを挿し込んで検電ドライバを当接片２５３に接触させることで、鎖錠ばね２５を介して端子板２４に対する検電を行うことができる。   In the wiring device of the present embodiment configured as described above, a part of the terminal device (the bent piece 253b of the lock spring 25) 40 is exposed to the outside from the upper surface of the body 107 through the voltage detection hole 107c. . Here, as described above, since the terminal plate 24 and the lock spring 25 are both formed from a conductive material, the voltage detection driver is inserted into the contact piece 253 by inserting the voltage detection driver from the voltage detection hole 107c. By making the contact, the terminal plate 24 can be detected via the lock spring 25.

従って、本実施形態の配線器具では、電線の接続作業を容易に行うことができると共に、容易に検電を行うことができる。   Therefore, in the wiring device of the present embodiment, it is possible to easily perform electric wire connection work and to easily perform voltage detection.

また、検電孔１０７ｃが、解除レバー２６における連結部２６３の一部が移動するスペースとして兼用されることから、前記スペースを別途設ける必要がなくなり、配線器具の構造を簡略化することができる。   Further, since the detection hole 107c is also used as a space for moving a part of the connecting portion 263 in the release lever 26, it is not necessary to provide the space separately, and the structure of the wiring device can be simplified.

また、鎖錠ばね２５の折曲片２５３ｂ及び端子板２４の接触片２４１ａが、検電孔１０７ｃの貫通方向（上下方向）に重ねて配置されていることから、速結端子装置において検電ドライバが接触する箇所の強度を高めることができる。   In addition, since the bent piece 253b of the locking spring 25 and the contact piece 241a of the terminal plate 24 are arranged so as to overlap in the penetration direction (vertical direction) of the detection hole 107c, the detection driver in the quick connection terminal device. It is possible to increase the strength of the portion that contacts.

また、鎖錠ばね２５の折曲片２５３ｂが、端子板２４の接触片２４１ａよりも検電孔１０７ｃ側に配置されていることから、検電ドライバが、端子板２４の接触片２４１ａに直接触れることがなく、端子板２４が傷つくことを防止することができる。   In addition, since the bent piece 253b of the locking spring 25 is disposed closer to the detection hole 107c than the contact piece 241a of the terminal plate 24, the detection driver directly touches the contact piece 241a of the terminal plate 24. It is possible to prevent the terminal board 24 from being damaged.

また、速結端子装置を構成する端子装置２０（端子板２１及び鎖錠ばね２２）は、カバー１０２の前面から後方へ向けて突設されるリブ１０２ｂ、１０２ｃにより前方への移動が規制されている。   Further, the terminal device 20 (the terminal plate 21 and the lock spring 22) constituting the quick-connection terminal device is restricted from moving forward by ribs 102b and 102c protruding from the front surface of the cover 102 toward the rear. Yes.

以下、端子板２と電線Ｂとの接続方法について説明する。先ず、電線３０の先端部の被覆を剥がして露出させた芯線３０ａを電線挿入孔１０１ｂを介して器体１０内部に挿入する。この時、芯線３０ａの先端部が、鎖錠ばね２２の鎖錠部２２２を押圧することで鎖錠部２２２が連結部２２３に向かう方向に撓み、芯線３０ａが挿入方向に更に挿入可能となる。芯線３０ａを更に挿入すると、芯線３０ａの先端部が押圧部２２１を押圧することで押圧部２２１が連結部２２３に向かう方向に撓み、芯線３０ａが、押圧部２２１と端子板２１の接触部２１３との間で挟持される。これにより、電線３０が端子板２１と機械的且つ電気的に接続される。   Hereinafter, the connection method of the terminal board 2 and the electric wire B is demonstrated. First, the core wire 30a exposed by peeling off the coating of the tip of the electric wire 30 is inserted into the container body 10 through the electric wire insertion hole 101b. At this time, the distal end portion of the core wire 30a presses the lock portion 222 of the lock spring 22 to bend the lock portion 222 toward the connecting portion 223, and the core wire 30a can be further inserted in the insertion direction. When the core wire 30 a is further inserted, the distal end portion of the core wire 30 a presses the pressing portion 221, whereby the pressing portion 221 is bent in the direction toward the connecting portion 223, and the core wire 30 a is connected to the pressing portion 221 and the contact portion 213 of the terminal plate 21. Sandwiched between. Thereby, the electric wire 30 is mechanically and electrically connected to the terminal plate 21.

ここで、押圧部２２１は、ばね性を有していることから、接触部２１３に向かう方向に復元力が働き、芯線３０ａは押圧部２２１の押圧力によって接触部２１３に所定の圧で接触する。また、芯線３０ａを引き抜こうとすると、鎖錠部２２２が芯線３０ａに食い込むことで芯線３０ａが抜け止めされるので、電線３０と端子板２１との接続を容易に解除できないようになっている。   Here, since the pressing portion 221 has a spring property, a restoring force acts in a direction toward the contact portion 213, and the core wire 30 a contacts the contact portion 213 with a predetermined pressure by the pressing force of the pressing portion 221. . Further, when the core wire 30a is pulled out, the core wire 30a is prevented from coming off by the locking portion 222 biting into the core wire 30a, so that the connection between the electric wire 30 and the terminal plate 21 cannot be easily released.

また、電線３０と端子板２１との接続を解除する際には、器体１０の貫通孔１０１ｃを介して解除レバー２３の突片２３１を押圧する。これにより、解除レバー２３が前方へ移動し、当該解除レバー２３における押圧突片２３２が、鎖錠ばね２２の鎖錠部２２２を接触部２１３側へ撓ませる。これにより、電線３０に対する抜け止めが解除され、当該電線３０を器体１０内から容易に引き抜くことが可能となる。   Further, when the connection between the electric wire 30 and the terminal plate 21 is released, the protruding piece 231 of the release lever 23 is pressed through the through hole 101 c of the container body 10. As a result, the release lever 23 moves forward, and the pressing protrusion 232 on the release lever 23 deflects the locking portion 222 of the locking spring 22 toward the contact portion 213. Thereby, the retaining with respect to the electric wire 30 is released, and the electric wire 30 can be easily pulled out from the inside of the container body 10.

上記構成からなる本実施形態の配線器具では、器体１０に収納された端子装置２０の端子板２１が、器体（ボディ１０１）１０に形成された検電孔１０１ｄから、外部に露出している。そのため、例えば検電ドライバ等の検査器具を検電孔１０１ｄに挿し込むことで、検電を容易に行うことができる。なお、本実施形態では、検電孔１０１ｄが、器体１０の側面（図８における上面）に形成されているが、検電孔１０１ｄの位置はこれに限定されず、器体１０におけるその他の面（例えば、前面や後面）等に形成されていてもよい。ここで、検電孔１０１ｄは、器体１０において後方側に形成されることがより好ましい。   In the wiring device of the present embodiment configured as described above, the terminal plate 21 of the terminal device 20 housed in the container body 10 is exposed to the outside from the detection hole 101d formed in the container body (body 101) 10. Yes. Therefore, for example, by inserting an inspection instrument such as a voltage detection driver into the voltage detection hole 101d, voltage detection can be performed easily. In this embodiment, the detection hole 101d is formed on the side surface (upper surface in FIG. 8) of the device body 10, but the position of the detection hole 101d is not limited to this, and other positions in the device body 10 are also included. It may be formed on a surface (for example, a front surface or a rear surface). Here, it is more preferable that the detection hole 101d is formed on the rear side in the vessel body 10.

また、本実施形態では、一対の検電孔１０１ｄが、ボディ１０１の上面にのみ形成されているが、上面と下面との両方に形成されていてもよい。   In the present embodiment, the pair of detection holes 101d are formed only on the upper surface of the body 101, but may be formed on both the upper surface and the lower surface.

従って、本実施形態の配線器具では、電線の接続作業を容易に行うことができると共に、容易に検電を行うことができる。   Therefore, in the wiring device of the present embodiment, it is possible to easily perform electric wire connection work and to easily perform voltage detection.

また、接触部２１３の下面に押圧部２２１が当接し、接触部２１３の上面が検電孔１０１ｄを介して外部に露出していることから、導電部である端子板２１（接触部２１３）に検電ドライバが直接接触し、より正確に検電を行うことができる。   In addition, since the pressing portion 221 contacts the lower surface of the contact portion 213 and the upper surface of the contact portion 213 is exposed to the outside through the detection hole 101d, the terminal plate 21 (contact portion 213) which is a conductive portion is exposed. The voltage detection driver can directly contact and perform voltage detection more accurately.
