In the following description, three directions orthogonal to each other in the space are referred to as a width direction, a vertical direction, and a depth direction for convenience.
The circuit breaker 11 is a direct current and alternating current type, and is used for overload protection and short circuit protection of various circuits in the low voltage distribution system, and here, a single pole type is shown. The blocking method is electromagnetic. The circuit breaker 11 has main circuit terminals on one end side and the other end side in the vertical direction, and a detachable wiring connector 12 is attached to each main circuit terminal. As for the main circuit terminal, one end side in the vertical direction is the power source side (primary side or line side), the other end side in the vertical direction is the load side (secondary side or load side), and the wiring connector 12 is also connected to the power source side.

The leaf spring 53 is arranged between the U-shaped one end piece 64 and the other end piece 65 of the terminal plate 51 in a state in which the distal end portion 83 is slightly pressed (compressed) in the depth direction. The tip of the inner end surface of the other end piece 65 contacts directly below the raised portion 66 (see FIG. 10). That is, the tip 83 of the leaf spring 53 is urged toward the inner peripheral surface (pressing surface) of the other end piece 65. Therefore, when the terminal block 52 is fitted into the terminal plate 51, the distal end portion 83 is pressed toward the back side in the depth direction. When it is fitted to the specified position and the pressing of the tip 83 is released, the tip is restored to a position where it contacts the ridge 66 directly below.

端子カバー１６には、奥行方向の奥側から見た下面に、縦方向に沿って延びた凹溝９１が形成されており、断面形状は略Ｔ字状である。凹溝９１は、延長スライダ１８のレール４３に対して摺動可能な状態で嵌り合うことで、縦方向に沿った端子カバー１６の進退を許容する。
端子カバー１６には、奥行方向の手前側から見た上面のうち、各電線差込孔７４に対応する位置に、円形の電線差込開口９２が形成されている。また、縦方向の他端側から見た側面のうち、切欠７５に対応する位置には、切欠９３（第二の切欠）が形成されている。また、奥行方向の手前側から見た上面のうち、各工具差込孔７６に対応する位置には、略四角形の工具差込開口９４が形成されている。 The terminal cover 16 is formed with a concave groove 91 extending in the longitudinal direction on the lower surface viewed from the depth side in the depth direction, and has a substantially T-shaped cross section. The recessed groove 91 allows the terminal cover 16 to advance and retreat along the vertical direction by fitting with the rail 43 of the extension slider 18 in a slidable state.
In the terminal cover 16, a circular wire insertion opening 92 is formed at a position corresponding to each wire insertion hole 74 on the upper surface viewed from the front side in the depth direction. In addition, a notch 93 (second notch) is formed at a position corresponding to the notch 75 in the side surface viewed from the other end side in the vertical direction. Further, a substantially rectangular tool insertion opening 94 is formed at a position corresponding to each tool insertion hole 76 on the upper surface viewed from the front side in the depth direction.

端子カバー１６には、幅方向の一端側から見た側面のうち縦方向の一端側に、一つの貫通孔９５が形成され、幅方向の他端側から見た側面のうち縦方向の一端側には、二つの貫通孔９５が形成されている。貫通孔９５は、夫々、端子ブロック５２の突起７７に対してスナップフィットによって嵌り合う。また、端子カバー１６の内部を奥行方向の手前側から見た床面には、一つの凹部９６が形成されている。凹部９６は、端子ブロック５２の突起７９に対してスナップフィットによって嵌り合う。また、端子カバー１６の内部を奥行方向の奥側から見た天井面のうち、縦方向の一端側には、電気機器側のねじ端子の工具挿入穴に係合される係合部である一つの突起９７が形成されている。突起９７は、縦方向の他端側に向かうほど奥行方向の奥側に出っ張る傾斜面を有し、ケース体３１の連通口３４に対してスナップフィットによって嵌り合う。 The terminal cover 16 is formed with one through hole 95 on one end side in the vertical direction among the side surfaces viewed from one end side in the width direction, and one end side in the vertical direction among the side surfaces viewed from the other end side in the width direction. Two through holes 95 are formed. The through holes 95 are fitted into the protrusions 77 of the terminal block 52 by snap fitting. In addition, one recess 96 is formed on the floor surface of the inside of the terminal cover 16 as viewed from the front side in the depth direction. The recess 96 fits with the protrusion 79 of the terminal block 52 by snap fit. Further, among the ceiling surface of the inside of the terminal cover 16 as viewed from the back side in the depth direction, one end side in the vertical direction is an engaging portion that is engaged with the tool insertion hole of the screw terminal on the electrical equipment side. Two protrusions 97 are formed. The protrusion 97 has an inclined surface that protrudes toward the back side in the depth direction as it goes to the other end side in the vertical direction, and fits to the communication port 34 of the case body 31 by a snap fit.

一方、端子カバー１６の組み付けは、負荷側の場合、端子カバー１６の凹溝９１を、延長スライダ１８のレール４３に嵌め合わせ、端子カバー１６を縦方向の一端側へと押し込む。そして、端子カバー１６の貫通孔９５と端子ブロック５２の突起７７とが嵌り合い、端子カバー１６の凹部９６と端子ブロック５２の突起７９とが嵌り合い、且つ端子カバー１６の突起９７とケース体３１の連通口３４とが嵌り合う。これにより、端子モジュール１５及びケース体３１に対して端子カバー１６が固定される。電源側の場合は、延長スライダ１８が存在しないので、凹溝９１とレール４３との嵌め合わせが省略される。 The terminal module 15 is assembled by inserting the insertion piece 61 of the terminal plate 51 into the terminal block of the main circuit terminal through the communication port 32 and inserting the protrusion 78 of the terminal block 52 into the through hole 35 of the case body 31.

The communication port 34 is fitted. Thereby, the terminal cover 16 is fixed to the terminal module 15 and the case body 31. In the case of the power supply side, since the extension slider 18 does not exist, the fitting of the concave groove 91 and the rail 43 is omitted.

次に、電線の差し込み及び引き抜きについて説明する。
図１０は、配線用接続器具の断面図である。
ここでは、縦方向及び奥行方向と平行で、電線差込孔７４及び工具差込孔７６を通る断面を示す。
電線差込孔７４には、奥行方向の奥側に、奥側に向かうほど小径となるテーパ面８０が形成されている。
電線差込孔７４及び工具差込孔７６は、夫々、板ばね５３の先端部８３に向かって形成されている。したがって、板ばね５３の先端部８３は、工具差込孔７６における奥行方向の奥側、及び電線差込孔７４における奥行方向の奥側を順に通過し、先端が隆起部６６の真下に接触している。 Next, insertion and extraction of electric wires will be described.
FIG. 10 is a cross-sectional view of the connection tool for wiring.
Here, a cross section parallel to the longitudinal direction and the depth direction and passing through the wire insertion hole 74 and the tool insertion hole 76 is shown.
In the electric wire insertion hole 74, a tapered surface 80 having a smaller diameter toward the back side is formed on the back side in the depth direction.
The electric wire insertion hole 74 and the tool insertion hole 76 are formed toward the distal end portion 83 of the leaf spring 53, respectively. Therefore, the distal end portion 83 of the leaf spring 53 sequentially passes through the depth side of the tool insertion hole 76 in the depth direction and the depth side of the wire insertion hole 74 in the depth direction, and the distal end contacts the ridge portion 66 directly below. ing.

図１１は、配線用接続器具の断面図である（電線差し込み後）。
電線１０１の先端には、カラー１０２の付いたフェルール１０３が圧着されている。フェルール１０３の先端側には、先端に向かうほど小径となるテーパ面１０４が形成されている。圧着後のフェルール１０３は、断面形状が例えば略四角形である。
電線差込開口９２及び電線差込孔７４にフェルール１０３が差し込まれると、フェルール１０３に押されて板ばね５３の主に湾曲部８２が弾性変形する。そして、先端部８３の先端と他端片６５の内周面との間にフェルール１０３が差し込まれると、板ばね５３の弾性力によってフェルール１０３が他端片６５の内周面に押し付けられ、且つ引き抜き方向の変位が抑制される。 FIG. 11 is a cross-sectional view of the connection tool for wiring (after inserting the electric wire).
A ferrule 103 with a collar 102 is crimped to the tip of the electric wire 101. A tapered surface 104 having a smaller diameter toward the distal end is formed on the distal end side of the ferrule 103. The ferrule 103 after crimping has a substantially square cross-sectional shape, for example.
When the ferrule 103 is inserted into the wire insertion opening 92 and the wire insertion hole 74, the bending portion 82 of the leaf spring 53 mainly elastically deforms by being pushed by the ferrule 103. When the ferrule 103 is inserted between the tip of the tip 83 and the inner peripheral surface of the other end piece 65, the ferrule 103 is pressed against the inner peripheral surface of the other end piece 65 by the elastic force of the leaf spring 53, and The displacement in the drawing direction is suppressed.

フェルール１０３の差し込みは、カラー１０２のテーパ面１０４が電線差込孔７４のテーパ面８０に当接した位置で停止する。フェルール１０３の差し込みが完了した状態で、カラー１０２の基端位置が切欠７５及び９３の下端位置よりも上側にあるように、切欠７５及び９３の深さが設定されている。
こうして、フェルール１０３は、他端片６５に電気的に接続されると共に、板ばね５３を介して一端片６４に電気的に接続されており、その結果、主回路端子に対して電気的に接続される。
図１２は、配線用接続器具の断面図である（工具差し込み後）。
工具１０５には、例えばマイナスドライバを使用する。
工具差込開口９４及び工具差込孔７６に工具１０５が差し込まれると、工具１０５に押されて板ばね５３の主に湾曲部８２が弾性変形し、板ばね５３の弾性力から解放されたときに、フェルール１０３の引き抜きが許容される。 The insertion of the ferrule 103 stops at a position where the tapered surface 104 of the collar 102 contacts the tapered surface 80 of the wire insertion hole 74. The depths of the notches 75 and 93 are set so that the base end position of the collar 102 is above the lower end positions of the notches 75 and 93 in a state where the insertion of the ferrule 103 is completed.
Thus, the ferrule 103 is electrically connected to the other end piece 65 and also electrically connected to the one end piece 64 via the leaf spring 53, and as a result, electrically connected to the main circuit terminal. Is done.
FIG. 12 is a cross-sectional view of the connection tool for wiring (after tool insertion).
As the tool 105, for example, a minus driver is used.
When the tool 105 is inserted into the tool insertion opening 94 and the tool insertion hole 76, the bending portion 82 of the leaf spring 53 is elastically deformed by being pushed by the tool 105 and released from the elastic force of the leaf spring 53. In addition, the withdrawal of the ferrule 103 is allowed.

《作用》
次に実施形態の主要な作用について説明する。
回路遮断器１１のねじ端子３３に、直接、電線１０１を挟み込むこともできるが、配線を増やしたり入れ替えたりする必要が生じると、その度にねじ端子３３を緩め再び締め付けなければならず、簡便さの点で改善の余地があった。また、ねじ端子３３の締め忘れや締め付けトルクの不足が生じる可能性もあった。
そこで、差し込み方式で配線を接続可能な配線用接続器具１２を、ねじ端子３３に取り付けている。すなわち、端子板５１をねじ端子３３に締め付ければ、その後は、端子カバー１６の電線差込開口９２を介して端子ブロック５２の電線差込孔７４にフェルール１０３を差し込むだけで、ねじ端子３３に電線１０１を電気的に接続することができる。したがって、この配線用接続器具１２を追加するだけで、ねじ端子３３への接続を差し込み方式に変換でき、電線接続の作業性を向上させることができる。 <Action>
Next, main functions of the embodiment will be described.
The electric wire 101 can be directly inserted into the screw terminal 33 of the circuit breaker 11. However, when it is necessary to increase or replace the wiring, the screw terminal 33 must be loosened and tightened again each time. There was room for improvement. Further, there is a possibility that the screw terminal 33 is forgotten to be tightened or the tightening torque is insufficient.
Therefore, the connection tool for wiring 12 that can connect the wiring by the insertion method is attached to the screw terminal 33. That is, if the terminal plate 51 is fastened to the screw terminal 33, then the ferrule 103 is simply inserted into the wire insertion hole 74 of the terminal block 52 through the wire insertion opening 92 of the terminal cover 16, and then the screw terminal 33 is attached. The electric wire 101 can be electrically connected. Therefore, the connection to the screw terminal 33 can be converted into the insertion method only by adding the connection tool 12 for wiring, and the workability of the electric wire connection can be improved.

電線差込孔７４にフェルール１０３が差し込まれると、フェルール１０３に押されて板ばね５３が弾性変形する。そして、先端部８３の先端と他端片６５の内周面との間にフェルール１０３が差し込まれると、板ばね５３の弾性力によってフェルール１０３が他端片６５の内周面に押し付けられ、且つ引き抜き方向の変位が抑制される。したがって、電線１０１の緩みや抜け落ちを抑制できる。
一方、工具差込孔７６に工具１０５が差し込まれると、工具１０５に押されて板ばね５３が弾性変形し、板ばね５３の弾性力からフェルール１０３が解放される。このように、工具１０５を用いることで、フェルール１０３を容易に引き抜くことができる。 When the ferrule 103 is inserted into the electric wire insertion hole 74, the ferrule 103 is pushed and the leaf spring 53 is elastically deformed. When the ferrule 103 is inserted between the tip of the tip 83 and the inner peripheral surface of the other end piece 65, the ferrule 103 is pressed against the inner peripheral surface of the other end piece 65 by the elastic force of the leaf spring 53, and The displacement in the drawing direction is suppressed. Therefore, loosening and dropping off of the electric wire 101 can be suppressed.
On the other hand, when the tool 105 is inserted into the tool insertion hole 76, the leaf spring 53 is elastically deformed by being pushed by the tool 105, and the ferrule 103 is released from the elastic force of the leaf spring 53. Thus, the ferrule 103 can be easily pulled out by using the tool 105.

端子ブロック５２には、電線差込孔７４にフェルール１０３を差し込んだ状態で、カラー１０２を軸直角方向から目視可能な切欠７５が形成され、端子カバー１６にも、切欠７５に対応する位置に切欠９３が形成されている。これにより、カラー１０２を容易に確認することができ、誤配線を抑制することができる。
端子カバー１６は、端子モジュール１５の全周を覆っているので、端子板５１への接触を確実に防ぐことができる。端子カバー１６は、奥行方向の手前側から見た上面が、縦方向の一端側へと延長されており、主回路端子におけるねじ端子３３の上面を覆っている。これにより、ねじ端子３３への接触をより確実に防ぐことができる。
端子ブロック５２や端子カバー１６は、樹脂等の絶縁体によって成形されるため、スナップフィット等による固定が容易である。 The terminal block 52 is formed with a notch 75 in which the collar 102 can be seen from the direction perpendicular to the axis with the ferrule 103 inserted into the wire insertion hole 74, and the terminal cover 16 is also notched at a position corresponding to the notch 75. 93 is formed. Thereby, the collar 102 can be easily confirmed, and erroneous wiring can be suppressed.
Since the terminal cover 16 covers the entire circumference of the terminal module 15, contact with the terminal plate 51 can be reliably prevented. The terminal cover 16 has an upper surface viewed from the front side in the depth direction extended to one end side in the vertical direction and covers the upper surface of the screw terminal 33 in the main circuit terminal. Thereby, the contact to the screw terminal 33 can be prevented more reliably.
Since the terminal block 52 and the terminal cover 16 are formed of an insulator such as a resin, they can be easily fixed by snap fit or the like.

ケース体３１と端子ブロック５２とを、スナップフィットによって嵌め合わせているので、端子ブロック５２のがたつきを抑制できる。また、端子ブロック５２と端子カバー１６とを、スナップフィットによって嵌め合わせているので、端子カバー１６のがたつきを抑制できる。
一つの配線用接続器具１２につき、二本の電線を差し込めるので、分岐配線や渡り配線を容易に行なうことができる。特に電源側の主回路端子では、渡り配線を行なうことが多いので、配線作業が容易となる。
負荷側には、延長スライダ１８を設けているので、配線用接続器具１２を取り付けた状態でも、任意にスライダ１７を引き出すことができ、レール２６に対する回路遮断器１１の着脱を行なうことができる。 Since the case body 31 and the terminal block 52 are fitted together by snap fitting, rattling of the terminal block 52 can be suppressed. Moreover, since the terminal block 52 and the terminal cover 16 are fitted together by snap fit, rattling of the terminal cover 16 can be suppressed.
Since two electric wires can be inserted into one wiring connection device 12, branch wiring and crossover wiring can be easily performed. In particular, since the main circuit terminal on the power source side often performs crossover wiring, wiring work is facilitated.
Since the extension slider 18 is provided on the load side, the slider 17 can be arbitrarily pulled out even when the wiring connector 12 is attached, and the circuit breaker 11 can be attached to and detached from the rail 26.

《変形例》
上記の実施形態では、二つの電線差込孔７４を幅方向に沿って配列しているが、これに限定されるものではなく、例えば何れか一方を縦方向の一端側に僅かにずらし、千鳥状に配列してもよい。これによれば、各電線差込孔７４の拡径要求にも容易に対応することができる。また、一つの配線用接続器具１２につき、二つの電線差込孔７４を形成しているが、これに限定されるものではなく、三つ以上の電線差込孔７４を形成してもよい。
また、一極型の回路遮断器について説明したが、これに限定されるものではなく、二極型や三極型にも適用できる。
また、回路遮断器１１への適用について説明したが、これに限定されるものではない。他にも、電気機器である電磁接触器や、付属装置である端子台式の補助スイッチ、また端子台式の警報スイッチ等にも適用できる。要は、ねじ端子によって電線を挟み込むものであれば、他の如何なる電気機器や付属装置にも適用可能である。 <Modification>
In the above embodiment, the two electric wire insertion holes 74 are arranged along the width direction. However, the present invention is not limited to this. For example, either one is slightly shifted to one end side in the vertical direction, You may arrange in a shape. According to this, it is possible to easily cope with a request for expanding the diameter of each wire insertion hole 74. Moreover, although the two electric wire insertion holes 74 are formed for one wiring connection device 12, the present invention is not limited to this, and three or more electric wire insertion holes 74 may be formed.
Moreover, although the unipolar circuit breaker has been described, the present invention is not limited to this, and can be applied to a bipolar or tripolar type.
Moreover, although the application to the circuit breaker 11 was demonstrated, it is not limited to this. In addition, the present invention can also be applied to electromagnetic contactors that are electrical devices, terminal block type auxiliary switches that are accessory devices, terminal block type alarm switches, and the like. In short, the present invention can be applied to any other electric device or accessory device as long as the electric wire is sandwiched between the screw terminals.
