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.

従来より、スイッチやコンセント等の配線器具への電線の結線を容易にしたり、接続の均一化を行って接続信頼性を確保する等の目的で、ねじによらずに結線可能な所謂速結端子装置（ねじ無し端子装置とも呼ばれる。）が提供されている。   Conventionally, so-called fast connection terminals that can be connected without using screws for the purpose of facilitating the connection of electric wires to wiring devices such as switches and outlets, and ensuring connection reliability by making the connection uniform. A device (also referred to as a screwless terminal device) is provided.

従来の速結端子装置は、略コ字状に形成された端子板と、端子板の内側に配設される錠ばねとを備えている。錠ばねは端子板の一方の脚と当接する中央片と、中央片の一端側よりＳ字状に延設された押圧片と、中央片の他端側よりＪ字状に延設された鎖錠片とが一体に形成されている。そして、端子板の他方の脚と押圧片並びに鎖錠片との間に電線（導体）が差し込まれると、押圧片によって電線が端子板に押圧されるとともに、鎖錠片の先端が電線に当接して電線が抜け止めされるものである。   A conventional quick connection terminal device includes a terminal plate formed in a substantially U-shape and a lock spring disposed inside the terminal plate. The lock spring has a central piece that comes into contact with one leg of the terminal plate, a pressing piece that extends in an S shape from one end of the central piece, and a chain that extends in a J shape from the other end of the central piece. The lock piece is integrally formed. When an electric wire (conductor) is inserted between the other leg of the terminal plate and the pressing piece and the locking piece, the electric wire is pressed against the terminal plate by the pressing piece, and the tip of the locking piece contacts the electric wire. The electric wire is prevented from coming off in contact.

また、この種の速結端子装置は解除釦を備えている。すなわち、速結端子装置に接続された電線を外す場合、マイナスドライバなどの工具を用いて解除釦を移動させれば、解除釦が鎖錠片を押圧して鎖錠片の先端を電線から離すことにより、電線を容易に引き抜くことができる。   Also, this type of quick connection terminal device includes a release button. That is, when removing the electric wire connected to the quick-connect terminal device, if the release button is moved using a tool such as a flat-blade screwdriver, the release button presses the locking piece and separates the tip of the locking piece from the electric wire. Thus, the electric wire can be easily pulled out.

しかしながら、特許文献１に記載されているような従来周知の速結端子装置においては、錠ばねが端子板に対して固定されておらず、比較的自由に姿勢が変わってしまう。そのため、電線の挿入時に鎖錠片が電線側に巻き込まれてしまい、押圧片による押圧力が電線に十分に作用しなくなって端子板と電線との接触信頼性が低下してしまう虞があった。   However, in the conventionally known quick coupling terminal device as described in Patent Document 1, the lock spring is not fixed to the terminal plate, and the posture changes relatively freely. Therefore, the locking piece is caught on the electric wire side when the electric wire is inserted, and the pressing force by the pressing piece does not sufficiently act on the electric wire, so that the contact reliability between the terminal plate and the electric wire may be lowered. .

本発明は上記事情に鑑みて為されたものであり、電線と端子板との接触信頼性を向上した速結端子装置を提供することにある。   This invention is made | formed in view of the said situation, and is providing the quick connection terminal device which improved the contact reliability of an electric wire and a terminal board.

接触片１０の下端部は、図３〜図５に示すように略へ字形に屈曲され、下端が左向き（電線１２０から離れる向き）に傾斜するとともに下端の上に右向き（電線１２０に近付く向き）に突出する突起１０ａが形成されている。また、接触片１０の上端部における貫通孔１４の下方には、前後方向を軸方向とし右向き（電線１２０に近付く向き）に突出する半円筒形状の突起１０ｂが打ち出し加工によって突設されている。   3 to 5, the lower end of the contact piece 10 is bent into a substantially square shape, and the lower end is inclined leftward (in a direction away from the electric wire 120) and rightward on the lower end (in the direction approaching the electric wire 120). A protrusion 10a is formed so as to protrude from the surface. Further, a semi-cylindrical protrusion 10b that protrudes rightward (direction approaching the electric wire 120) with the front-rear direction as the axial direction is provided below the through hole 14 at the upper end of the contact piece 10 by a punching process.

第１の囲み片１２，１２は、図１及び図３に示すように前後方向から見て略台形の部分と当該台形の部分の先端（右端）から上向きに突出する略正方形の部分とが一体に構成されている。また第２の囲み片１３は、図４及び図５に示すように支持片１１の左右方向における略中央部が切り起こされて構成されている。故に、電線挿入孔１０２から挿入される電線１２０は、接触片１０と一対の第１の囲み片１２，１２と第２の囲み片１３とに前後左右から囲まれた空間に配置されることとなる（図９参照）。ここで、第１の囲み片１２，１２並びに第２の囲み片１３はそれぞれ端子板１を構成する金属板の一部が曲げ起こされてなり、図９に示すように、第１の囲み片１２，１２間の間隔よりも第２の囲み片１３の幅が狭くなっている。これにより、順送プレス加工で端子板１を形成する際、第２の囲み片１３を曲げ加工するためのパンチを、先に加工された第１の囲み片１２，１２と干渉しない幅に設定できるために加工金型の設計が容易になるという利点がある。尚、支持片１１においては、第２の囲み片１３が切り起こし形成されることにより、上下方向から見た形状が略矩形であり且つ前方に開口した切欠溝１１ａが設けられている。   As shown in FIGS. 1 and 3, each of the first surrounding pieces 12 and 12 has a substantially trapezoidal portion and a substantially square portion protruding upward from the tip (right end) of the trapezoidal portion when viewed from the front-rear direction. It is configured. Further, the second surrounding piece 13 is formed by cutting and raising a substantially central portion in the left-right direction of the support piece 11 as shown in FIGS. 4 and 5. Therefore, the electric wire 120 inserted from the electric wire insertion hole 102 is disposed in a space surrounded by the contact piece 10, the pair of first surrounding pieces 12, 12 and the second surrounding piece 13 from the front, rear, left and right. (See FIG. 9). Here, each of the first surrounding pieces 12 and 12 and the second surrounding piece 13 is formed by bending a part of the metal plate constituting the terminal plate 1, and as shown in FIG. The width of the second surrounding piece 13 is narrower than the distance between 12 and 12. Thereby, when forming the terminal board 1 by progressive press processing, the punch for bending the second surrounding piece 13 is set to a width that does not interfere with the previously processed first surrounding pieces 12 and 12. Therefore, there is an advantage that the processing mold can be easily designed. In the support piece 11, the second surrounding piece 13 is cut and raised, so that a notch groove 11 a having a substantially rectangular shape viewed from the top and bottom and opened forward is provided.

錠ばね２は、図３〜図５に示すように弾性を有する導電性の板材（例えば、金属板）を略Ｃ字形状に曲成することにより、電線１２０が挿入される空間を挟んで端子板１の接触片１０と対向する中央片２０と、中央片２０における電線挿入孔１０２側（下側）の端部から電線１２０の挿入向き（上向き）に沿って接触片１０に近づく向きに傾斜し且つ先端部分が電線１２０に当接する鎖錠片２１と、接触片１０における電線１２０との接触面（右側面）と反対側の面（左側面）に当接する当接片２２と、当接片２２並びに中央片２０における電線挿入孔１０２と反対側（上側）の端部同士を連結する連結片２３とが一体に形成されてなる。   As shown in FIGS. 3 to 5, the lock spring 2 is a terminal that sandwiches a space into which the electric wire 120 is inserted by bending an elastic conductive plate (for example, a metal plate) into a substantially C shape. A center piece 20 facing the contact piece 10 of the plate 1 and an inclination toward the contact piece 10 along the insertion direction (upward) of the electric wire 120 from the end of the center piece 20 on the wire insertion hole 102 side (lower side). And a locking piece 21 whose tip is in contact with the electric wire 120, an abutment piece 22 in contact with the surface (left side) opposite to the contact surface (right side) of the contact piece 10 with the electric wire 120, The piece 22 and the connecting piece 23 that connects the opposite ends (upper side) of the wire insertion hole 102 in the central piece 20 are integrally formed.

中央片２０と鎖錠片２１との連結部分が半円弧状に湾曲しており、鎖錠片２１に右向きの力が加わると当該湾曲部分が縮径することで鎖錠片２１が撓む（変位する）ことになる。また連結片２３は、端子板１の支持片１１に設けられた切欠溝１１ａを通過して支持片１１と上下方向に交差する段部２３ａを有している。すなわち、ボディ１００の収納室１０１内に収納された状態においては、段部２３ａが支持片１１の切欠溝１１ａに挿通されるため、連結片２３の段部２３ａより左側の部分が端子板１の支持片１１によって下方から支持され、連結片２３の段部２３ａより右側の部分が端子板１の支持片１１を下方から支持することになる。ここで、電線１２０が接続されていない状態において、錠ばね２の鎖錠片２１先端を端子板１の接触片１０の接触面に当接させているが、接触片１０において鎖錠片２１先端が当接する部位には鎖錠片２１先端と嵌合する溝１０ｄが形成されている。   The connecting portion between the central piece 20 and the lock piece 21 is curved in a semicircular arc shape, and when a rightward force is applied to the lock piece 21, the curved portion is reduced in diameter so that the lock piece 21 is bent ( Will be displaced). Further, the connecting piece 23 has a step portion 23 a that passes through the notch groove 11 a provided in the support piece 11 of the terminal plate 1 and intersects the support piece 11 in the vertical direction. That is, when the body 100 is housed in the housing chamber 101, the step portion 23 a is inserted into the cutout groove 11 a of the support piece 11, so that the portion on the left side of the step portion 23 a of the connecting piece 23 is the terminal plate 1. The support piece 11 is supported from below, and the portion on the right side of the stepped portion 23a of the connecting piece 23 supports the support piece 11 of the terminal board 1 from below. Here, in the state where the electric wire 120 is not connected, the tip of the lock piece 21 of the lock spring 2 is brought into contact with the contact surface of the contact piece 10 of the terminal plate 1. A groove 10d that fits into the distal end of the locking piece 21 is formed at a site where the contact is made.

上述のように構成される端子板１と錠ばね２は、図１及び図８に示すようにボディ１００の収納室１０１内に収納される。そして、電線挿入孔１０２を通して外部から収納室１０１内に電線１２０が挿入されると、電線１２０の先端で押された鎖錠片２１が接触片１０から離れる向き（右向き）に撓み、鎖錠片２１が撓むにつれて電線１２０の先端が上へ移動する。電線１２０が所定の位置まで挿入されると、図２に示すように鎖錠片２１の先端が電線１２０に当接して反挿入向き（下向き）に抜け止めされるとともに、錠ばね２の湾曲部分の復元力（ばね力）により鎖錠片２１が電線１２０を接触片１０の接触面に弾接させて電線１２０と接触片１０を接触させることができる。   The terminal plate 1 and the lock spring 2 configured as described above are housed in the housing chamber 101 of the body 100 as shown in FIGS. When the electric wire 120 is inserted into the storage chamber 101 from the outside through the electric wire insertion hole 102, the locking piece 21 pushed by the tip of the electric wire 120 bends away from the contact piece 10 (rightward), and the locking piece As the wire 21 is bent, the tip of the electric wire 120 moves upward. When the electric wire 120 is inserted to a predetermined position, as shown in FIG. 2, the tip of the locking piece 21 abuts against the electric wire 120 and is prevented from coming off in the anti-insertion direction (downward), and the curved portion of the lock spring 2 The restoring piece (spring force) allows the locking piece 21 to bring the electric wire 120 into elastic contact with the contact surface of the contact piece 10 so that the electric wire 120 and the contact piece 10 can be brought into contact with each other.

ここで、本実施形態の速結端子装置では、電線１２０の接続時において、電線挿入孔１０２より挿入される電線１２０が鎖錠片２１に当たると端子板１の接触片１０に当接している当接片２２を支点として鎖錠片２１が接触片１０から離れる向き（図１における反時計回り）に錠ばね２が回転することになる。そのため、電線１２０の挿入時に鎖錠片２１が電線１２０側に巻き込まれることがなく、電線の挿入時に鎖錠片が電線側に巻き込まれていた従来例と比較して、電線１２０と端子板１との接触信頼性を向上することができる。 Here, in the quick connection terminal device of the present embodiment, when the electric wire 120 is connected, when the electric wire 120 inserted from the electric wire insertion hole 102 hits the locking piece 21 , the contact is brought into contact with the contact piece 10 of the terminal plate 1. The lock spring 2 rotates in a direction (counterclockwise in FIG. 1) in which the locking piece 21 is separated from the contact piece 10 with the contact piece 22 as a fulcrum. Therefore, the locking piece 21 is not wound on the electric wire 120 side when the electric wire 120 is inserted, and the electric wire 120 and the terminal plate 1 are compared with the conventional example in which the locking piece is wound on the electric wire side when the electric wire is inserted. The contact reliability can be improved.

また本実施形態の速結端子装置においては、接触片１０が２つの突起１０ａ，１０ｂの先端面のみで電線１２０と接触することになるので（図２参照）、接触片１０の接触面全体と接触する場合と比較して、電線１２０と接触片１０との接触圧が増大して接触状態を安定させることができる。ここで、突起１０ｂが半円筒形状に形成されているので、電線１２０が傾いても突起１０ｂと電線１２０との接触角度が変わり難いために接触状態を安定させることができるという利点がある。さらに、これら２つの突起１０ａ，１０ｂは、電線１２０が接触片１０に接触している状態で電線１２０を挟んで鎖錠片２１の先端部分と対向する位置に対し、電線１２０の軸方向（上下方向）に沿った両側に分けて設けられているので、電線１２０を３点（突起１０ａ，１０ｂと鎖錠片２１先端）で支持することによっても接触状態を安定させることができるものである。   Moreover, in the quick connection terminal device of this embodiment, since the contact piece 10 comes into contact with the electric wire 120 only at the tip surfaces of the two protrusions 10a and 10b (see FIG. 2), the entire contact surface of the contact piece 10 and Compared with the case where it contacts, the contact pressure of the electric wire 120 and the contact piece 10 increases, and a contact state can be stabilized. Here, since the protrusion 10b is formed in a semi-cylindrical shape, there is an advantage that the contact state can be stabilized because the contact angle between the protrusion 10b and the electric wire 120 is not easily changed even when the electric wire 120 is inclined. Furthermore, these two protrusions 10a and 10b are arranged in the axial direction (up and down) of the electric wire 120 with respect to a position facing the tip portion of the locking piece 21 with the electric wire 120 sandwiched in a state where the electric wire 120 is in contact with the contact piece 10. The contact state can be stabilized by supporting the electric wire 120 at three points (protrusions 10a and 10b and the distal end of the locking piece 21).

ところで、接触片１０における第１の囲み片１２，１２の下側には、いわゆるＳＲ形状の案内突部１０ｃ，１０ｃがそれぞれ右向き（電線１２０に近付く向き）に突設されている（図３〜図５参照）。すなわち、電線１２０（導体）が撚り線である場合、電線１２０の撚りが解けて素線が広がったとしても案内突部１０ｃ，１０ｃに乗り上げることによって鎖錠片と案内突部１０ｃ，１０ｃとの間に電線１２０が確実に挟持され、しかも案内突部１０ｃ，１０ｃがＳＲ形状であることによって電線１２０はできるだけ両案内突部１０ｃ，１０ｃの間を通るように誘導されることになる。要するに、電線１２０が撚り線であってもばらばらに広がる可能性を低減して接触状態を安定させることができる。   By the way, so-called SR-shaped guide protrusions 10c and 10c are respectively provided on the lower side of the first surrounding pieces 12 and 12 of the contact piece 10 so as to protrude rightward (toward the electric wire 120) (see FIG. 3). (See FIG. 5). That is, when the electric wire 120 (conductor) is a stranded wire, even if the strand of the electric wire 120 is unwound and the element wire spreads, the cable 120 and the guide ridges 10c, 10c are moved by riding on the guide ridges 10c, 10c. The electric wire 120 is securely sandwiched between them, and the guide protrusions 10c and 10c are SR-shaped, so that the electric wire 120 is guided to pass between the guide protrusions 10c and 10c as much as possible. In short, even if the electric wire 120 is a stranded wire, the possibility of spreading apart can be reduced and the contact state can be stabilized.

また、第１の囲み片１２，１２が接触片１０に設けられていることにより、電線１２０が単線であれば径方向（前後方向）における電線１２０の移動範囲を第１の囲み片１２，１２で規制することができる。さらに、電線１２０が撚り線であれば素線のばらける範囲を第１の囲み片１２，１２で規制することができるので、電線１２０と端子板１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、第１の囲み片１２，１２を先端部分が上向きに突出する形状に形成しているため、電線１２０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。またさらに、端子板１の支持片１１に第２の囲み片１３が設けられているため、接触片１０から離れる向きの電線１２０の移動を第２の囲み片１３で規制することができる。尚、第２の囲み片１３が第１の囲み片１２，１２と相互に直交しているため、電線１２０の移動範囲やばらける範囲をさらに確実に規制することができる。   In addition, since the first surrounding pieces 12 and 12 are provided on the contact piece 10, if the electric wire 120 is a single wire, the movement range of the electric wire 120 in the radial direction (front-rear direction) is set as the first surrounding pieces 12 and 12. Can be regulated. Further, if the electric wire 120 is a stranded wire, the range in which the strands can be separated can be regulated by the first surrounding pieces 12 and 12, so that the contact reliability between the electric wire 120 and the terminal plate 1 is further improved. There is. Moreover, in the present embodiment, since the first surrounding pieces 12 and 12 are formed in a shape in which the tip portion protrudes upward, it is possible to more reliably regulate the moving range and the range of the electric wire 120. Furthermore, since the second surrounding piece 13 is provided on the support piece 11 of the terminal plate 1, the movement of the electric wire 120 away from the contact piece 10 can be restricted by the second surrounding piece 13. In addition, since the 2nd surrounding piece 13 is mutually orthogonally crossed with the 1st surrounding pieces 12 and 12, the movement range of the electric wire 120 and the range which can be separated can be controlled still more reliably.

ここで、接触片１０において鎖錠片２１先端が当接する部位に鎖錠片２１先端と嵌合する溝１０ｄが形成されており、鎖錠片２１に押された電線１２０（特に撚り線の素線）が溝１０ｄ（凹部）に落ち込むため、電線１２０を確実に抜け止めすることができるものである（図１１参照）。但し、このような凹部（溝１０ｄ）を設ける代わりに、接触片１０において電線１２０を挟んで鎖錠片２１の先端部分と対向する位置に、電線１２０の軸方向（上下方向）と交差する方向（前後方向）に沿った複数の溝（図示せず）を設けてもよく、これら複数の溝によって撚り線からなる電線１２０を確実に抜け止めすることができる。   Here, in the contact piece 10, a groove 10 d that fits the tip of the lock piece 21 is formed at a portion where the tip of the lock piece 21 abuts, and an electric wire 120 (particularly a strand of strands) pushed by the lock piece 21 is formed. Since the wire) falls into the groove 10d (recessed portion), the electric wire 120 can be reliably prevented from coming off (see FIG. 11). However, instead of providing such a recess (groove 10d), a direction intersecting the axial direction (vertical direction) of the electric wire 120 at a position facing the tip portion of the locking piece 21 across the electric wire 120 in the contact piece 10. You may provide the some groove | channel (not shown) along (front-back direction), and the electric wire 120 which consists of a strand wire can be reliably prevented by these several groove | channels.

ところで、ボディ１００の収納室１０１内に収納された状態においては、連結片２３の段部２３ａより左側の部分が端子板１の支持片１１によって下方から支持されるため、ボディ１００によらず、端子板１のみで錠ばね２を固定（支持）することができる。また、ボディ１００の収納室１０１内に収納された状態においては、段部２３ａが支持片１１の切欠溝１１ａに挿通されるため、錠ばね２と端子板１を位置決めすることができる。   By the way, in the state accommodated in the storage chamber 101 of the body 100, the portion on the left side of the stepped portion 23a of the connecting piece 23 is supported from below by the support piece 11 of the terminal plate 1. The lock spring 2 can be fixed (supported) only by the terminal plate 1. Moreover, in the state accommodated in the storage chamber 101 of the body 100, since the step part 23a is inserted in the notch groove 11a of the support piece 11, the lock spring 2 and the terminal board 1 can be positioned.

また本実施形態の速結端子装置では、端子板１の接触片１０が電線１２０との当接方向（左右方向）において可撓性を有しているので、電線挿入孔１０２に対して電線１２０が傾いた場合においても接触片１０が電線１２０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１２０がばらけている場合や径の小さい（細い）電線１２０であっても接触片１０と鎖錠片２１とで電線１２０を弾性挟持することにより、端子板１と錠ばね２の接触状態を安定させることができる。尚、接触片１０が撓む範囲はボディ１００における収納室１０１の内壁によって規制されているので、電線１２０が傾いたりした場合であっても接触片１０の塑性変形が防止できるものである。   Moreover, in the quick connection terminal device of this embodiment, since the contact piece 10 of the terminal plate 1 has flexibility in the contact direction (left-right direction) with the electric wire 120, the electric wire 120 with respect to the electric wire insertion hole 102. Even in the case of tilting, the contact piece 10 can follow the movement of the electric wire 120 to always ensure a stable contact state. Further, even when the electric wire 120 made of stranded wires is scattered or the electric wire 120 having a small diameter (thin) is formed by elastically holding the electric wire 120 between the contact piece 10 and the locking piece 21, the terminal plate 1 and The contact state of the lock spring 2 can be stabilized. In addition, since the range in which the contact piece 10 bends is regulated by the inner wall of the storage chamber 101 in the body 100, the plastic deformation of the contact piece 10 can be prevented even when the electric wire 120 is tilted.

次に解除部材３について説明する。解除部材３は合成樹脂成型品からなり、図６に示すように半円板状の支持部３０，３０と、矩形平板状の操作部３１と、支持部３０，３０と操作部３１を連結する略三角形板状の連結部３２，３２とを有して全体が略コ字形に形成されている。また、一対の連結部３２，３２にはそれぞれ押動部３３，３３が突設されている。押動部３３，３３は扁平な略三角柱状に形成され、後述するように鎖錠片２１と対向する側（右側）の斜面で鎖錠片２１に接離自在に当接するとともに、当該斜面と反対側（左側）の角部で接触片１０に接離自在に当接する。すなわち、本実施形態においては第１及び第２の押動部が押動部３３として一体に形成されている。   Next, the release member 3 will be described. The release member 3 is made of a synthetic resin molded product, and as shown in FIG. 6, the semicircular plate-like support portions 30, 30, the rectangular flat plate-like operation portion 31, and the support portions 30, 30 and the operation portion 31 are connected. It has substantially triangular plate-like connecting portions 32, 32 and is formed in a substantially U shape as a whole. In addition, push portions 33 and 33 project from the pair of connecting portions 32 and 32, respectively. The pushing portions 33, 33 are formed in a flat and substantially triangular prism shape, and come into contact with and separate from the locking piece 21 on the side (right side) facing the locking piece 21, as will be described later. It abuts on and away from the contact piece 10 at the opposite (left) corner. That is, in the present embodiment, the first and second pushing portions are integrally formed as the pushing portion 33.

一方、ボディ１００の長手方向の両側面には各収納室１０１，１０１と通じる縦溝１０３，１０３が各一対ずつ並設されている（図７参照）。そして、解除部材３は縦溝１０３，１０３を通して操作部３１がボディ１００の外に露出され、一対の連結部３２，３２の間に接触片１０と錠ばね２が配置されるようにしてボディ１００の収納室１０１内に収納される。ここで、収納室１０１内には半円弧状の摺動面を有した軸受け台１０４，１０４が設けられており（図１参照）、収納室１０１内に収納された解除部材３の支持部３０，３０が軸受け台１０４，１０４に載置されることにより、支持部３０，３０を支点として解除部材３が回動自在にボディ１００に支持される。   On the other hand, a pair of longitudinal grooves 103, 103 communicating with the respective storage chambers 101, 101 are arranged in parallel on both side surfaces in the longitudinal direction of the body 100 (see FIG. 7). The release member 3 has the operating portion 31 exposed to the outside of the body 100 through the longitudinal grooves 103, 103, and the contact piece 10 and the lock spring 2 are disposed between the pair of connecting portions 32, 32. Is stored in the storage chamber 101. Here, bearing bases 104 and 104 having a semicircular arc-shaped sliding surface are provided in the storage chamber 101 (see FIG. 1), and the support portion 30 of the release member 3 stored in the storage chamber 101. , 30 are mounted on the bearing bases 104, 104, so that the release member 3 is rotatably supported by the body 100 with the support portions 30, 30 as fulcrums.

而して、速結端子装置に接続された電線１２０を取り外すには、縦溝１０３，１０３を通して器体の側面に露出している操作部３１を指で押し上げるように操作すればよい。すなわち、図１に示すように操作部３１を上方へ押し上げるように操作すれば、支持部３０，３０を支点にして解除部材３が時計回りに回動し、初めに押動部３３，３３の上側の角部（第２の押動部）がそれぞれ接触片１０の前後方向両端部を押圧することで接触片１０の下端部を電線１２０から離れる向き（左向き）に変位させる。解除部材３が時計回りにさらに回動すると、今度は押動部３３，３３の右側の斜面（第１の押動部）がそれぞれ鎖錠片２１の前後方向両端部を押圧することにより、電線１２０に当接している鎖錠片２１を電線１２０から離す向きに変位させて電線１２０の取り外しが可能となる。   Thus, in order to remove the electric wire 120 connected to the quick connection terminal device, the operation unit 31 exposed on the side surface of the container body through the longitudinal grooves 103 and 103 may be operated to be pushed up with a finger. That is, as shown in FIG. 1, if the operation unit 31 is operated to be pushed upward, the release member 3 rotates clockwise with the support units 30, 30 as fulcrums. The upper corner (second pusher) presses both ends of the contact piece 10 in the front-rear direction, thereby displacing the lower end of the contact piece 10 away from the electric wire 120 (leftward). When the release member 3 is further rotated clockwise, the right slope (the first pushing portion) of the pushing portions 33 and 33 each presses the both end portions in the front-rear direction of the locking piece 21, thereby The electric wire 120 can be removed by displacing the locking piece 21 in contact with 120 in a direction away from the electric wire 120.

従来の速結端子装置では工具を使って解除釦を操作しながら電線を引き抜かなければならないため、一方の手で配線器具の器体を持ち、他方の手に持った工具を操作孔に挿入して解除釦を操作した状態では両手が塞がれてしまうために電線を電線挿入孔から引き抜くことが困難であった。これに対して本実施形態の速結端子装置では、器体を持った手の指（例えば、親指）で器体の側面に露出する解除部材３の操作部３１を操作して解除部材３を回動させると電線１２０を抜け止めしている鎖錠片２１を電線１２０から離すことができ、一方の手で器体の保持と解除部材３の操作を同時に行い、他方の手で電線１２０を引き抜くことができる。そのため、従来の速結端子装置に比較して電線１２０の取り外し作業が容易に行える。また鎖錠片２１だけでなく接触片１０も解除部材３で変位させているため、線径の細い単線あるいは撚り線からなる電線１２０を取り外す際の作業性を向上できるものである。尚、撚り線の素線が細い場合、解除部材３を操作して接触片１０と鎖錠片２１をそれぞれ反対方向に変位させた状態で電線挿入孔１０２から電線１２０を挿入すれば、鎖錠片２１の先端が接触片１０から離れた状態で両者の間に電線１２０を挿入することができるので、電線接続時の作業性も向上できる。尚、接触片１０は収納室１０１の内壁（図１における左側の内壁）に当接することで変位量（撓む範囲）が規制される。   In the conventional quick-connect terminal device, the wire must be pulled out while operating the release button using a tool, so hold the wiring fixture with one hand and insert the tool held in the other hand into the operation hole. When the release button is operated, both hands are blocked, and it is difficult to pull out the wire from the wire insertion hole. On the other hand, in the quick connection terminal device of the present embodiment, the release member 3 is operated by operating the operation portion 31 of the release member 3 exposed on the side of the vessel body with a finger (for example, thumb) of the hand holding the vessel body. When it is turned, the locking piece 21 that prevents the electric wire 120 from coming off can be separated from the electric wire 120, the holding of the body and the operation of the release member 3 are simultaneously performed with one hand, and the electric wire 120 is held with the other hand. Can be pulled out. Therefore, it is possible to easily remove the electric wire 120 as compared with the conventional quick connection terminal device. Since not only the locking piece 21 but also the contact piece 10 is displaced by the release member 3, the workability when removing the electric wire 120 made of a single wire or a stranded wire with a small wire diameter can be improved. In addition, when the strand of strands is thin, if the wire 120 is inserted from the wire insertion hole 102 with the contact member 10 and the lock piece 21 displaced in opposite directions by operating the release member 3, the lock Since the electric wire 120 can be inserted between the two pieces in a state where the tip of the piece 21 is away from the contact piece 10, workability at the time of connecting the electric wire can be improved. The contact piece 10 is in contact with the inner wall (the left inner wall in FIG. 1) of the storage chamber 101, so that the amount of displacement (the bending range) is regulated.

また本実施形態の速結端子装置では、解除部材３を略コ字状に形成し、一対の連結部３２，３２に設けられている押動部３３，３３で鎖錠片２１並びに接触片１０を押動しているので、鎖錠片２１並びに接触片１０をよりスムーズに電線１２０から引き離すことができるものである。   Moreover, in the quick connection terminal device of the present embodiment, the release member 3 is formed in a substantially U shape, and the locking piece 21 and the contact piece 10 are formed by the pressing portions 33 and 33 provided in the pair of connecting portions 32 and 32. , The locking piece 21 and the contact piece 10 can be separated from the electric wire 120 more smoothly.

ところで、解除部材３が回動する際に支持部３０，３０並びに操作部３１と反対側の端部（右上の端部）が錠ばね２と干渉してしまう虞がある。そのために本実施形態の速結端子装置では、操作部３１が手動操作されて連結部３３，３３が支持部３０を支点として回動する際に端子板１の第１の囲み片１２，１２に乗り上げる突部３４，３４が各々設けられている。つまり、突部３４，３４を第１の囲み片１２，１２に乗り上げさせることにより、連結部３２，３２の間隔を前後方向に拡げて錠ばね２との干渉を防止し、解除部材３をスムーズに回動させることができる。   By the way, when the release member 3 rotates, there is a possibility that the end portion (upper right end portion) opposite to the support portions 30 and 30 and the operation portion 31 may interfere with the lock spring 2. Therefore, in the quick connection terminal device of this embodiment, when the operation part 31 is manually operated and the connection parts 33 and 33 rotate about the support part 30 as a fulcrum, the first surrounding pieces 12 and 12 of the terminal plate 1 Protruding portions 34 and 34 are provided, respectively. That is, by causing the protrusions 34 and 34 to ride on the first surrounding pieces 12 and 12, the interval between the connecting portions 32 and 32 is increased in the front-rear direction to prevent interference with the lock spring 2, and the release member 3 is made smooth. Can be rotated.

また接触片１０や鎖錠片２１の変位量が多すぎると塑性変形してしまう虞があるため、押動部３３，３３が変位する範囲、すなわち、解除部材３の回動範囲を規制する必要がある。そのために本実施形態の速結端子装置では、図１に示すようにボディ１００の縦溝１０３，１０３に対向するカバー１１０の下面からリブ１１１を垂下させ、解除部材３の連結部３２，３２をリブ１１１の下面に当接させることで解除部材３の回動範囲を規制している。但し、回動範囲を規制するためのリブを器体（カバー１１０）ではなく端子板１に設けても構わない。   Further, if the displacement amount of the contact piece 10 or the lock piece 21 is too large, there is a risk of plastic deformation. Therefore, it is necessary to regulate the range in which the pushing portions 33 and 33 are displaced, that is, the rotation range of the release member 3. There is. Therefore, in the quick connection terminal device of the present embodiment, as shown in FIG. 1, the rib 111 is suspended from the lower surface of the cover 110 facing the longitudinal grooves 103, 103 of the body 100, and the connecting portions 32, 32 of the release member 3 are connected. The rotation range of the release member 3 is restricted by contacting the lower surface of the rib 111. However, a rib for regulating the rotation range may be provided on the terminal plate 1 instead of the container (cover 110).

ここで、鎖錠片２１の塑性変形を防止するに当たって、解除部材３の回動範囲を規制する方法以外にも、図１０に示すように端子板１の第２の囲み片１３を下方に延長して規制部１５を形成する方法がある。つまり、規制部１５が鎖錠片２１に当接することで鎖錠片２１の撓み量（変位量）を規制することができるのである。   Here, in order to prevent the plastic deformation of the locking piece 21, the second surrounding piece 13 of the terminal plate 1 is extended downward as shown in FIG. 10 in addition to the method of restricting the rotation range of the release member 3. Then, there is a method of forming the restricting portion 15. That is, the amount of deflection (displacement) of the lock piece 21 can be restricted by the restricting portion 15 coming into contact with the lock piece 21.

ここで、ボディ１００の短手方向に隣接する収納室１０１，１０１内にそれぞれ収納される速結端子装置が送り配線用でない場合には、これらの速結端子装置間を電気的に絶縁する必要がある。そのために本実施形態の速結端子装置では、図７及び図８に示すように隣接する収納室１０１，１０１の間を隔絶する絶縁壁１０５をボディ１００に設けている。これにより、隣接する複数の収納室１０１内に収納されている端子板１や錠ばね２同士の絶縁距離を大きくして短絡事故を防ぐことができる。   Here, when the quick connection terminal devices stored in the storage chambers 101 and 101 adjacent to each other in the short direction of the body 100 are not for the feed wiring, it is necessary to electrically insulate these quick connection terminal devices from each other. There is. Therefore, in the quick connection terminal device of the present embodiment, the body 100 is provided with an insulating wall 105 that isolates the adjacent storage chambers 101, 101 as shown in FIGS. Thereby, the insulation distance of the terminal board 1 and the lock spring 2 accommodated in the adjacent some storage chamber 101 can be enlarged, and a short circuit accident can be prevented.
