Description

接続装置Connection device
　本発明は、電線用挿入穴に電線を差し込むだけで当該電線との強固な接続状態を形成するプッシュイン機構を備えた接続装置に関する。 The present invention relates to a connecting device provided with a push-in mechanism that forms a strong connection state with the electric wire simply by inserting the electric wire into the insertion hole for the electric wire.
　接続装置の一例であるスイッチ装置には、プッシュイン機構を備えたものが多く存在する。プッシュイン機構は、一般的に、電線用挿入穴に差し込まれた電線が接触する端子と、電線を係止してその端子への当該電線の接触状態を維持する係止バネと、によって構成されており、係止バネは、固定された第１脚部と、当該第１脚部から湾曲して延びた湾曲部と、当該湾曲部を介して第１脚部に弾性的に連結された部分であって電線用挿入穴への電線の差込みに応じて変位する第２脚部と、を有している（例えば、特許文献１参照）。 Many switch devices, which are examples of connection devices, are equipped with a push-in mechanism. The push-in mechanism is generally composed of a terminal that the electric wire inserted into the insertion hole for the electric wire comes into contact with, and a locking spring that locks the electric wire and maintains the contact state of the electric wire with the terminal. The locking spring is a fixed first leg portion, a curved portion curved and extended from the first leg portion, and a portion elastically connected to the first leg portion via the curved portion. It has a second leg portion that is displaced according to the insertion of the electric wire into the insertion hole for the electric wire (see, for example, Patent Document 1).
　一方、このようなプッシュイン機構において電線を取り外すためには、係止バネの弾性力に抗して第２脚部を変位させることにより、係止バネと電線との係止状態を解除する必要がある。そこで、特許文献１では、電線用挿入穴とは別に工具差込穴を設けておき、当該工具差込穴に差し込んだ工具で第２脚部を押して変位させる技術が提案されている。 On the other hand, in order to remove the electric wire in such a push-in mechanism, it is necessary to release the locked state between the locking spring and the electric wire by displacing the second leg portion against the elastic force of the locking spring. There is. Therefore, Patent Document 1 proposes a technique in which a tool insertion hole is provided separately from the electric wire insertion hole, and the second leg is pushed and displaced by the tool inserted into the tool insertion hole.
特開２０１９－９６４７０号公報JP-A-2019-96470
　上述したスイッチ装置は、電線を介して様々な回路に組み込まれる。一方、回路に組み込まれた後に当該回路内に導通不良が発生した場合、どの箇所で導通不良が発生しているのかをチェックして発生箇所を特定する必要があり、従って、スイッチ装置に対しても導通不良の有無をチェックする必要がある。そこで、スイッチ装置が上記工具差込穴を備えている場合には、テスタに接続されたプローブを工具差込穴に挿入して係止バネ（金属製）の第２脚部に接触させることにより、当該係止バネを通じて導通不良をチェックするといった方法が従来は用いられていた。 The above-mentioned switch device is incorporated into various circuits via electric wires. On the other hand, if a continuity failure occurs in the circuit after it is incorporated in the circuit, it is necessary to check where the continuity failure occurs and identify the location where it occurs. Therefore, for the switch device It is also necessary to check for poor continuity. Therefore, when the switch device is provided with the tool insertion hole, the probe connected to the tester is inserted into the tool insertion hole and brought into contact with the second leg of the locking spring (metal). Conventionally, a method of checking for poor continuity through the locking spring has been used.
　電線を取り外す場合には、電線と係止バネとの係止状態が解除されればよいので、工具差込穴に工具が挿入されるときの挿入の程度は、工具が、第２脚部に最初に接触したときの位置から少し押される程度であることが多かった。従って、電線を取り外すときの工具の挿入で係止バネが塑性変形してしまうことは少なかった。しかし、工具差込穴を導通不良のチェックにも用いた場合には、プローブが、係止バネに確実に接触するように奥まで強く差し込まれることが多かった。このため、プローブの挿入によって係止バネが塑性変形し、それが原因で係止バネの機能（電線を係止する機能）が低下する虞があった。 When removing the electric wire, it is sufficient to release the locked state between the electric wire and the locking spring. Therefore, when the tool is inserted into the tool insertion hole, the tool is inserted into the second leg. In many cases, it was pushed slightly from the position when it first touched. Therefore, it was rare that the locking spring was plastically deformed by inserting a tool when removing the electric wire. However, when the tool insertion hole is also used for checking for poor continuity, the probe is often strongly inserted all the way in so as to make sure contact with the locking spring. For this reason, the locking spring may be plastically deformed by the insertion of the probe, which may reduce the function of the locking spring (the function of locking the electric wire).
　そこで本発明の目的は、係止バネの機能を低下させずに導通不良のチェックを行うことが可能な接続装置を提供することである。 Therefore, an object of the present invention is to provide a connecting device capable of checking for poor continuity without deteriorating the function of the locking spring.
　本発明に係る接続装置は、電線用挿入穴が設けられた装置ケースと、当該電線用挿入穴に差し込まれた電線が接触する端子と、電線を係止してその端子への当該電線の接触状態を維持する係止バネと、を備える。係止バネは、装置ケース内に固定された第１脚部と、当該第１脚部から湾曲して延びた湾曲部と、当該湾曲部を介して第１脚部に弾性的に連結された部分であって電線用挿入穴への電線の差込みに応じて変位する第２脚部と、を有している。そして、装置ケースには、係止バネの湾曲部へのプローブの接触を可能にするプローブ用挿入穴が設けられている。 In the connecting device according to the present invention, a device case provided with an insertion hole for an electric wire, a terminal to which an electric wire inserted into the insertion hole for an electric wire comes into contact, and a terminal for which the electric wire is locked and the electric wire comes into contact with the terminal It is provided with a locking spring that maintains the state. The locking spring was elastically connected to the first leg portion fixed in the device case, the curved portion curved and extended from the first leg portion, and the first leg portion via the curved portion. It has a second leg portion that is a portion and is displaced according to the insertion of the electric wire into the insertion hole for the electric wire. The device case is provided with a probe insertion hole that allows the probe to come into contact with the curved portion of the locking spring.
　上記接続装置において、湾曲部は、湾曲することで強度が高くなった部分であり、従って、外力が加わった場合でも変形しにくい。そして上記接続装置によれば、係止バネのうちの強度が高い湾曲部に、プローブ用挿入穴を通じてプローブを接触させることができる。このため、たとえプローブ用挿入穴にプローブが強く差し込まれたとしても、係止バネには塑性変形が生じにくい。 In the above connection device, the curved portion is a portion whose strength is increased by being curved, and therefore, it is difficult to be deformed even when an external force is applied. Then, according to the connection device, the probe can be brought into contact with the curved portion of the locking spring having high strength through the insertion hole for the probe. Therefore, even if the probe is strongly inserted into the probe insertion hole, the locking spring is unlikely to undergo plastic deformation.
　上記接続装置は、プローブ用挿入穴に挿入されたプローブが係止バネの湾曲部に接触したときに生じる当該プローブの押圧力を湾曲部の背面側で受け止める第１受止め部を更に備えていてもよい。この構成によれば、プローブを係止バネの湾曲部に接触させたときに、当該プローブの押圧力が、湾曲部の背面側で第１受止め部によって受け止められる。よって、係止バネの塑性変形を確実に防止できる。 The connecting device further includes a first receiving portion that receives the pressing force of the probe generated when the probe inserted into the insertion hole for the probe comes into contact with the curved portion of the locking spring on the back side of the curved portion. May be good. According to this configuration, when the probe is brought into contact with the curved portion of the locking spring, the pressing force of the probe is received by the first receiving portion on the back surface side of the curved portion. Therefore, the plastic deformation of the locking spring can be reliably prevented.
　上記接続装置において、プローブ用挿入穴は、係止バネの湾曲部へのプローブの接触だけでなく係止バネの第１脚部へもプローブの接触が可能となるように装置ケースに設けられていてもよい。この構成によれば、プローブ用挿入穴を通じて、係止バネのうちの固定された第１脚部にもプローブを接触させることが可能になる。 In the above connecting device, the probe insertion hole is provided in the device case so that the probe can be contacted not only with the curved portion of the locking spring but also with the first leg portion of the locking spring. You may. According to this configuration, the probe can also be brought into contact with the fixed first leg portion of the locking spring through the probe insertion hole.
　上記接続装置は、プローブ用挿入穴に挿入されたプローブが係止バネの第１脚部に接触したときに生じる当該プローブの押圧力を第１脚部の背面側で受け止める第２受止め部を更に備えていてもよい。この構成によれば、プローブを係止バネの第１脚部に接触させたときに、当該プローブの押圧力が、第１脚部の背面側で第２受止め部によって受け止められる。よって、プローブが第１脚部に押し付けられた場合にも、係止バネの塑性変形を確実に防止できる。 The connecting device has a second receiving portion that receives the pressing force of the probe generated when the probe inserted into the insertion hole for the probe comes into contact with the first leg portion of the locking spring on the back surface side of the first leg portion. Further may be provided. According to this configuration, when the probe is brought into contact with the first leg portion of the locking spring, the pressing force of the probe is received by the second receiving portion on the back surface side of the first leg portion. Therefore, even when the probe is pressed against the first leg portion, the plastic deformation of the locking spring can be reliably prevented.
　上記接続装置において、装置ケースには、係止バネの湾曲部へのプローブの接触を可能にするプローブ用挿入穴に代えて、係止バネの第１脚部へのプローブの接触を可能にするプローブ用挿入穴が設けられていてもよい。また、当該接続装置は、プローブ用挿入穴に挿入されたプローブが第１脚部に接触したときに生じる当該プローブの押圧力を第１脚部の背面側で受け止める受止め部を更に備えていてもよい。この構成によれば、プローブ用挿入穴を通じて、係止バネのうちの固定された第１脚部にプローブを接触させることが可能になる。また、プローブを係止バネの第１脚部に接触させたときに、当該プローブの押圧力が、第１脚部の背面側で受止め部によって受け止められる。よって、たとえプローブ用挿入穴にプローブが強く差し込まれたとしても、係止バネの塑性変形を確実に防止できる。 In the above connecting device, the device case allows the probe to come into contact with the first leg of the locking spring instead of the probe insertion hole that allows the probe to come into contact with the curved portion of the locking spring. A probe insertion hole may be provided. Further, the connecting device further includes a receiving portion that receives the pressing force of the probe generated when the probe inserted in the insertion hole for the probe comes into contact with the first leg portion on the back surface side of the first leg portion. May be good. According to this configuration, the probe can be brought into contact with the fixed first leg portion of the locking spring through the probe insertion hole. Further, when the probe is brought into contact with the first leg portion of the locking spring, the pressing force of the probe is received by the receiving portion on the back surface side of the first leg portion. Therefore, even if the probe is strongly inserted into the probe insertion hole, the plastic deformation of the locking spring can be reliably prevented.
　本発明によれば、係止バネの機能を低下させずに接続装置に対する導通不良のチェックを行うことが可能になる。 According to the present invention, it is possible to check for poor continuity of the connecting device without deteriorating the function of the locking spring.

As shown in these figures, the switch device comprises a device case 1. The bottom surface 1a of the device case 1 is provided with electric wire insertion holes 11a and 11b on the left and right for inserting the electric wires W1 and W2, respectively. Although not particularly limited, in the present embodiment, two insertion holes 11a and 11b for electric wires are provided on the left and right sides (see FIG. 1B).
　スイッチ装置は更に、電線用挿入穴１１ａ及び１１ｂに電線Ｗ１及びＷ２をそれぞれ差し込むだけで当該電線Ｗ１及びＷ２との強固な接続状態を形成するプッシュイン機構２Ａ及び２Ｂと、当該プッシュイン機構２Ａ及び２Ｂによる電線Ｗ１及びＷ２との強固な接続状態をそれぞれ解除するための解除機構３Ａ及び３Ｂと、２本の電線Ｗ１及びＷ２の間の導通及び遮断を切り替えるためのスイッチング機構４と、を備える（図２（Ａ）及び図３（Ａ）参照）。 The switch device further includes push-in mechanisms 2A and 2B that form a strong connection state with the electric wires W1 and W2 by simply inserting the electric wires W1 and W2 into the electric wire insertion holes 11a and 11b, respectively, and the push-in mechanism 2A and the switch device.

　＜プッシュイン機構＞
　装置ケース１の内部には、電線用挿入穴１１ａ及び１１ｂの奥側に空間１０ａ及び１０ｂがそれぞれ形成されており、当該空間１０ａ及び１０ｂ内にプッシュイン機構２Ａ及び２Ｂがそれぞれ構築されている（図２（Ａ）参照）。以下、プッシュイン機構２Ａの構成について具体的に説明する。尚、本実施形態では、プッシュイン機構２Ａ及び２Ｂとして同じ構成のものが用いられている。よって、プッシュイン機構２Ｂの構成については、以下の説明において、図面を参照しつつ、符号「１０ａ」、「１１ａ」、「２１Ａ」、「２２Ａ」、及び「Ｗ１」をそれぞれ、「１０ｂ」、「１１ｂ」、「２１Ｂ」、「２２Ｂ」、及び「Ｗ２」に読み替えることで説明できる。 <Push-in mechanism>
Spaces 10a and 10b are formed inside the device case 1 on the inner side of the electric wire insertion holes 11a and 11b, respectively, and push-in mechanisms 2A and 2B are constructed in the spaces 10a and 10b, respectively ( (See FIG. 2 (A)). Hereinafter, the configuration of the push-in mechanism 2A will be specifically described. In this embodiment, the push-in mechanisms 2A and 2B having the same configuration are used. Therefore, regarding the configuration of the push-in mechanism 2B, in the following description, the reference numerals “10a”, “11a”, “21A”, “22A”, and “W1” are referred to as “10b”, respectively, with reference to the drawings. This can be explained by reading "11b", "21B", "22B", and "W2".
　プッシュイン機構２Ａは、電線用挿入穴１１ａに差し込まれた電線Ｗ１が接触する端子２１Ａと、電線Ｗ１を係止して端子２１Ａへの当該電線Ｗ１の接触状態を維持する係止バネ２２Ａと、によって構成されている（図２（Ｂ）参照）。 The push-in mechanism 2A includes a terminal 21A to which the electric wire W1 inserted into the insertion hole 11a for the electric wire comes into contact, a locking spring 22A that locks the electric wire W1 and maintains the contact state of the electric wire W1 with the terminal 21A. (See FIG. 2 (B)).
　具体的には、端子２１Ａは、図３（Ｂ）に示されるように電線用挿入穴１１ａに電線Ｗ１が差し込まれて当該電線Ｗ１の先端部１０１が空間１０ａ内に達したときに、当該先端部１０１の側周面のうちの片側（図３（Ｂ）において左側）の面に接触するように空間１０ａ内に配置されている。より具体的には、端子２１Ａは、空間１０ａのうちの電線Ｗ１の先端部１０１が挿入される領域の片側の位置に、当該領域に沿って配置されている。 Specifically, as shown in FIG. 3B, the terminal 21A has a tip when the wire W1 is inserted into the wire insertion hole 11a and the tip 101 of the wire W1 reaches the space 10a. It is arranged in the space 10a so as to come into contact with one side (the left side in FIG. 3B) of the side peripheral surfaces of the portion 101. More specifically, the terminal 21A is arranged along the region 10a at a position on one side of the region in which the tip end 101 of the electric wire W1 is inserted.
　係止バネ２２Ａは、導電性を有する材料（金属など）で形成されており、装置ケース１内に固定された第１脚部２２１と、当該第１脚部２２１から湾曲して延びた湾曲部２２０と、当該湾曲部２２０を介して第１脚部２２１に弾性的に連結された第２脚部２２２と、を有している。 The locking spring 22A is made of a conductive material (metal or the like), and has a first leg portion 221 fixed in the device case 1 and a curved portion curved and extended from the first leg portion 221. It has 220 and a second leg portion 222 elastically connected to the first leg portion 221 via the curved portion 220.
　より具体的には、係止バネ２２Ａは、湾曲部２２０を底面１ａの方へ向けた状態で配置されている。そして、係止バネ２２Ａを保持する保持部品２３が空間１０ａ内に嵌め込まれており、その保持部品２３に設けられた留め部２３０に第１脚部２２１の端部２２１ａを係合させることにより、当該端部２２１ａが、空間１０ａのうちの電線Ｗ１の先端部１０１が挿入される領域に対して端子２１Ａとは反対側の位置に固定されている。また、第２脚部２２２は、上記領域への電線Ｗ１の先端部１０１の挿入が開始されると同時又はその直後に当該先端部１０１が接触するように、湾曲部２２０から端子２１Ａの方へ向けて延びている。尚、留め部２３０は、第１脚部２２１を空間１０ａ内で固定できるものであれば、図２（Ｂ）に示された形状や構成に限らず、他の様々な形状や構成に変形されてもよい。 More specifically, the locking spring 22A is arranged with the curved portion 220 facing the bottom surface 1a. Then, the holding component 23 for holding the locking spring 22A is fitted in the space 10a, and the end portion 221a of the first leg portion 221 is engaged with the fastening portion 230 provided on the holding component 23. The end portion 221a is fixed at a position opposite to the terminal 21A with respect to the region in the space 10a into which the tip end portion 101 of the electric wire W1 is inserted. Further, the second leg portion 222 is directed from the curved portion 220 toward the terminal 21A so that the tip portion 101 comes into contact with the tip portion 101 at the same time or immediately after the insertion of the tip portion 101 of the electric wire W1 into the above region is started. It extends toward. The fastening portion 230 is not limited to the shape and configuration shown in FIG. 2B, but can be deformed into various other shapes and configurations as long as the first leg portion 221 can be fixed in the space 10a. You may.
　従って、電線用挿入穴１１ａに電線Ｗ１が差し込まれて当該電線Ｗ１の先端部１０１が空間１０ａ内に挿入され始めると、第２脚部２２２が、先端部１０１によって押されることにより、第１脚部２２１との間の距離が小さくなる方向へ変位する。これにより、第２脚部２２２には、元の位置へ戻ろうとする復元力（弾性力）が生じ、この復元力が電線Ｗ１の先端部１０１に作用する。その後、先端部１０１が、図３（Ｂ）に示されるように係止バネ２２Ａの復元力に抗して更に空間１０ａ内に挿入されることにより、第２脚部２２２の端部２２２ａが、先端部１０１の側周面のうちの端子２１Ａとは反対側（図３（Ｂ）において右側）の面に対して斜めに当接する。 Therefore, when the electric wire W1 is inserted into the insertion hole 11a for the electric wire and the tip portion 101 of the electric wire W1 starts to be inserted into the space 10a, the second leg portion 222 is pushed by the tip portion 101, so that the first leg It is displaced in the direction in which the distance from the portion 221 becomes smaller. As a result, a restoring force (elastic force) that tries to return to the original position is generated in the second leg portion 222, and this restoring force acts on the tip portion 101 of the electric wire W1. After that, as shown in FIG. 3B, the tip portion 101 is further inserted into the space 10a against the restoring force of the locking spring 22A, so that the end portion 222a of the second leg portion 222 is formed. It diagonally contacts the surface of the peripheral surface of the tip portion 101 on the side opposite to the terminal 21A (on the right side in FIG. 3B).
　これにより、係止バネ２２Ａの復元力によって先端部１０１が端子２１Ａの方へ押圧され、その結果として、先端部１０１と端子２１Ａとの接触が確実なものとなる。また、第２脚部２２２の端部２２２ａが先端部１０１の側周面に対して斜めに当接することにより、電線用挿入穴１１ａから抜ける方向への力が電線Ｗ１に加わったときに、第２脚部２２２の端部２２２ａが先端部１０１の側周面に引っ掛かり、その結果として上記抜ける方向への先端部１０１の移動が阻止される。よって、上記プッシュイン機構２Ａによれば、電線用挿入穴１１ａに電線Ｗ１を差し込むだけで、当該電線Ｗ１の先端部１０１と端子２１Ａとの強固な接続状態が形成される。 As a result, the restoring force of the locking spring 22A presses the tip 101 toward the terminal 21A, and as a result, the contact between the tip 101 and the terminal 21A is ensured. Further, when the end portion 222a of the second leg portion 222 obliquely contacts the side peripheral surface of the tip portion 101 and a force is applied to the electric wire W1 in the direction of coming out of the electric wire insertion hole 11a, the second leg portion 222 is used. The end portion 222a of the two leg portions 222 is caught on the side peripheral surface of the tip portion 101, and as a result, the movement of the tip portion 101 in the pull-out direction is prevented. Therefore, according to the push-in mechanism 2A, a strong connection state between the tip portion 101 of the electric wire W1 and the terminal 21A is formed only by inserting the electric wire W1 into the insertion hole 11a for the electric wire.
　＜解除機構＞
　装置ケース１の底面１ａには、空間１０ａ及び１０ｂにそれぞれ連通した貫通穴１２ａ及び１２ｂが設けられている（図１（Ｂ）及び図２（Ａ）参照）。具体的には、貫通穴１２ａは、空間１０ａ内に配置された係止バネ２２Ａの第２脚部２２２の一部（本実施形態では、第２脚部２２２のうちの電線Ｗ１の先端部１０１が接触する部分よりも湾曲部２２０に近い部分）を臨むことができる位置に、電線用挿入穴１１ａに沿って設けられている（図２（Ｂ）参照）。同様に、貫通穴１２ｂは、空間１０ｂ内に配置された係止バネ２２Ｂの第２脚部２２２の一部（本実施形態では、第２脚部２２２のうちの電線Ｗ２の先端部１０１が接触する部分よりも湾曲部２２０に近い部分）を臨むことができる位置に、電線用挿入穴１１ｂに沿って設けられている。 <Release mechanism>
The bottom surface 1a of the device case 1 is provided with through holes 12a and 12b communicating with the spaces 10a and 10b, respectively (see FIGS. 1B and 2A). Specifically, the through hole 12a is a part of the second leg portion 222 of the locking spring 22A arranged in the space 10a (in the present embodiment, the tip portion 101 of the electric wire W1 in the second leg portion 222. It is provided along the electric wire insertion hole 11a at a position where it can face the curved portion 220 rather than the portion with which the wire comes into contact (see FIG. 2B). Similarly, the through hole 12b is a part of the second leg portion 222 of the locking spring 22B arranged in the space 10b (in the present embodiment, the tip portion 101 of the electric wire W2 in the second leg portion 222 is in contact with the through hole 12b. It is provided along the electric wire insertion hole 11b at a position where it can face the curved portion 220).
　そして貫通穴１２ａには、解除用操作子３１が、外部からの押し込みによって空間１０ａ内へ突き出るように挿入されており、これらによって解除機構３Ａが構成されている。このような解除機構３Ａによれば、プッシュイン機構２Ａによって電線Ｗ１の先端部１０１と端子２１Ａとの強固な接続状態が形成されている場合において、解除用操作子３１を押し込むことにより、当該解除用操作子３１の先端部で係止バネ２２Ａの第２脚部２２２を押すことが可能になる（図４参照）。具体的には、係止バネ２２Ａの復元力に抗して、第２脚部２２２を、第１脚部２２１との間の距離が小さくなる方向へ変位させることが可能になる。このように第２脚部２２２を変位させることにより、先端部１０１の側周面への第２脚部２２２の引っ掛かりが解除される。これにより、プッシュイン機構２Ａによる電線Ｗ１との強固な接続状態が解除され、その結果として、電線用挿入穴１１ａから電線Ｗ１を抜くことが可能になる。 Then, the release operator 31 is inserted into the through hole 12a so as to protrude into the space 10a by being pushed in from the outside, and the release mechanism 3A is configured by these. According to such a release mechanism 3A, when a strong connection state between the tip portion 101 of the electric wire W1 and the terminal 21A is formed by the push-in mechanism 2A, the release is performed by pushing the release operator 31. The second leg portion 222 of the locking spring 22A can be pushed by the tip end portion of the operator 31 (see FIG. 4). Specifically, the second leg portion 222 can be displaced in a direction in which the distance between the second leg portion 222 and the first leg portion 221 becomes smaller against the restoring force of the locking spring 22A. By displacing the second leg portion 222 in this way, the hooking of the second leg portion 222 on the side peripheral surface of the tip portion 101 is released. As a result, the strong connection state with the electric wire W1 by the push-in mechanism 2A is released, and as a result, the electric wire W1 can be pulled out from the electric wire insertion hole 11a.
　同様に、貫通穴１２ｂにも、解除用操作子３１が、外部からの押し込みによって空間１０ｂ内へ突き出るように挿入されており、これらによって解除機構３Ｂが構成されている（図２（Ａ）参照）。 Similarly, the release operator 31 is also inserted into the through hole 12b so as to protrude into the space 10b by being pushed in from the outside, and the release mechanism 3B is configured by these (see FIG. 2 (A)). ).
　＜スイッチング機構＞
　装置ケース１の内部における中央部分には、空間１０ａ及び１０ｂから隔離された別の空間１０ｃが形成されており、当該空間１０ｃ内にスイッチング機構４が構築されている（図２（Ａ）参照）。具体的には、スイッチング機構４は、固定接点４１Ａ及び４１Ｂと、可動接点４２Ａ及び４２Ｂと、操作子４３と、復帰バネ４４と、によって構成されている。 <Switching mechanism>
Another space 10c isolated from the spaces 10a and 10b is formed in the central portion inside the device case 1, and the switching mechanism 4 is constructed in the space 10c (see FIG. 2A). .. Specifically, the switching mechanism 4 is composed of fixed contacts 41A and 41B, movable contacts 42A and 42B, an operator 43, and a return spring 44.
　固定接点４１Ａ及び４１Ｂは、装置ケース１内に固定される接点である。本実施形態では、空間１０ａ内の端子２１Ａに連結された導電部材４０１Ａが、当該端子２１Ａから延びて空間１０ｃ内へ突き出ている。同様に、空間１０ｂ内の端子２１Ｂに連結された導電部材４０１Ｂが、当該端子２１Ｂから延びて空間１０ｃ内へ突き出ている。尚、図２（Ａ）では、その図が断面図であるが故に、導電部材４０１Ａ及び４０１Ｂと端子２１Ａ及び２１Ｂとが互いに分離しているかのように示されているが、実際にはそれらは互いに連結されている。そして、固定接点４１Ａ及び４１Ｂは、空間１０ｃ内に突き出た２つの導電部材４０１Ａ及び４０１Ｂの先端部にそれぞれ固定されている。 The fixed contacts 41A and 41B are contacts fixed in the device case 1. In the present embodiment, the conductive member 401A connected to the terminal 21A in the space 10a extends from the terminal 21A and protrudes into the space 10c. Similarly, the conductive member 401B connected to the terminal 21B in the space 10b extends from the terminal 21B and protrudes into the space 10c. In addition, in FIG. 2A, since the figure is a cross-sectional view, it is shown as if the conductive members 401A and 401B and the terminals 21A and 21B are separated from each other, but in reality, they are shown. They are connected to each other. The fixed contacts 41A and 41B are fixed to the tip portions of the two conductive members 401A and 401B protruding into the space 10c, respectively.
　可動接点４２Ａ及び４２Ｂはそれぞれ、それらを互いに導通させる導電部材４０２に、固定接点４１Ａ及び４１Ｂと対向する位置（図２（Ａ）では上方位置）にて固定されている。そして、可動接点４２Ａ及び４２Ｂは、導電部材４０２のよって互いの位置関係が保持された状態で、固定接点４１Ａ及び４１Ｂから離間した開放位置（図２（Ａ）参照）と、固定接点４１Ａ及び４１Ｂに接触した閉塞位置（不図示）と、の間を、装置ケース１の天面１ｂから上方へ突き出た操作子４３の上下動に応じて移動する。 The movable contacts 42A and 42B are fixed to the conductive member 402 that conducts them with each other at positions facing the fixed contacts 41A and 41B (upper position in FIG. 2A), respectively. The movable contacts 42A and 42B are separated from the fixed contacts 41A and 41B (see FIG. 2A) and the fixed contacts 41A and 41B while the positional relationship between the movable contacts 42A and 42B is maintained by the conductive member 402. It moves between the closed position (not shown) in contact with the device case 1 according to the vertical movement of the operator 43 protruding upward from the top surface 1b of the device case 1.
　そして本実施形態では、スイッチング機構４は、可動接点４２Ａ及び４２Ｂが常開接点となるように構成されている。具体的には、復帰バネ４４を操作子４３に作用させることにより、当該操作子４３を介して可動接点４２Ａ及び４２Ｂが常に開放位置へ向けて付勢されるように構成されている。 Then, in the present embodiment, the switching mechanism 4 is configured such that the movable contacts 42A and 42B are normally open contacts. Specifically, by acting the return spring 44 on the operator 43, the movable contacts 42A and 42B are always urged toward the open position via the operator 43.
　＜チェック用の構造＞
　本実施形態のスイッチ装置は、上述した機構（プッシュイン機構２Ａ及び２Ｂ、解除機構３Ａ及び３Ｂ、スイッチング機構４）に加えて、電線用挿入穴１１ａ及び１１ｂに電線Ｗ１及びＷ２がそれぞれ差し込まれた状態（具体的には、プッシュイン機構２Ａ及び２Ｂによる電線Ｗ１及びＷ２との強固な接続状態が形成されている場合。図３（Ａ）参照）において導通不良のチェックを可能にする構造（チェック用の構造）を更に備えている。 <Structure for checking>
In the switch device of the present embodiment, in addition to the above-mentioned mechanisms (push-in mechanisms 2A and 2B, release mechanisms 3A and 3B, switching mechanism 4), electric wires W1 and W2 are inserted into the electric wire insertion holes 11a and 11b, respectively. A structure (check) that enables a check for poor continuity in a state (specifically, when a strong connection state with the electric wires W1 and W2 is formed by the push-in mechanisms 2A and 2B. See FIG. 3 (A)). (Structure for) is further provided.
　本実施形態では、そのようなチェック用の構造として、プローブ用挿入穴５０ａ及び５０ｂが装置ケース１の底面１ａに設けられている（図１（Ｂ）、図２（Ａ）、及び図３（Ａ）参照）。具体的には、プローブ用挿入穴５０ａは、空間１０ａ内に配置された係止バネ２２Ａの湾曲部２２０のみを臨むことができるように設けられている。このようなプローブ用挿入穴５０ａによれば、図５に示されるように、テスタ（不図示）に接続された２本のプローブＰ１及びＰ２（プローブＰ２は不図示）のうちの一方のプローブＰ１を係止バネ２２Ａの湾曲部２２０にのみ接触させることが可能になる。同様に、プローブ用挿入穴５０ｂは、空間１０ｂ内に配置された係止バネ２２Ｂの湾曲部２２０のみを臨むことができるように設けられている。このようなプローブ用挿入穴５０ｂによれば、テスタに接続されたもう一方のプローブＰ２を係止バネ２２Ｂの湾曲部２２０にのみ接触させることが可能になる。 In the present embodiment, as a structure for such a check, probe insertion holes 50a and 50b are provided on the bottom surface 1a of the device case 1 (FIGS. 1 (B), 2 (A), and 3 (FIG. 3). See A)). Specifically, the probe insertion hole 50a is provided so that only the curved portion 220 of the locking spring 22A arranged in the space 10a can be faced. According to such a probe insertion hole 50a, as shown in FIG. 5, one of two probes P1 and P2 (probe P2 is not shown) connected to a tester (not shown) is probe P1. Can be brought into contact only with the curved portion 220 of the locking spring 22A. Similarly, the probe insertion hole 50b is provided so that only the curved portion 220 of the locking spring 22B arranged in the space 10b can face. According to such a probe insertion hole 50b, the other probe P2 connected to the tester can be brought into contact with only the curved portion 220 of the locking spring 22B.
　ここで、プッシュイン機構２Ａ及び２Ｂによる電線Ｗ１及びＷ２との強固な接続状態が形成されている場合、係止バネ２２Ａ及び２２Ｂは、電線Ｗ１及びＷ２の先端部１０１をそれぞれ介して端子２１Ａ及び２２Ｂと導通した状態になる（図３（Ａ）参照）。従って、そのような強固な接続状態が形成されている場合には、係止バネ２２Ａ及び２２Ｂを用いて（即ち、係止バネ２２Ａ及び２２ＢにプローブＰ１及びＰ２をそれぞれ接触させることで）、端子２１Ａ及び２１Ｂの間の導通不良をチェックすることができる。そして上記チェック用の構造によれば、そのような係止バネ２２Ａ及び２２ＢへのプローブＰ１及びＰ２の接触が可能になる。 Here, when a strong connection state with the electric wires W1 and W2 is formed by the push-in mechanisms 2A and 2B, the locking springs 22A and 22B are connected to the terminals 21A and the terminals 21A and 22B via the tips 101 of the electric wires W1 and W2, respectively. It becomes conductive with 22B (see FIG. 3 (A)). Therefore, when such a strong connection state is formed, the locking springs 22A and 22B are used (that is, by bringing the probes P1 and P2 into contact with the locking springs 22A and 22B, respectively). Poor continuity between 21A and 21B can be checked. Then, according to the above-mentioned check structure, the probes P1 and P2 can come into contact with such locking springs 22A and 22B.
　また、湾曲部２２０は、湾曲することで強度が高くなった部分であり、従って、外力が加わった場合でも変形しにくい。そして上記チェック用の構造によれば、係止バネ２２Ａ及び２２Ｂのうちの強度が高い湾曲部２２０にのみ、プローブ用挿入穴５０ａ及び５０ｂを通じてプローブＰ１及びＰ２をそれぞれ接触させることができる。このため、たとえプローブ用挿入穴５０ａ及び５０ｂにプローブＰ１及びＰ２がそれぞれ強く差し込まれたとしても、係止バネ２２Ａ及び２２Ｂには塑性変形が生じにくい。よって、本実施形態のスイッチ装置では、係止バネ２２Ａ及び２２Ｂの機能（電線を係止する機能）を低下させずに導通不良のチェックを行うことができる。 Further, the curved portion 220 is a portion whose strength is increased by being curved, and therefore, it is difficult to be deformed even when an external force is applied. Then, according to the above-mentioned check structure, the probes P1 and P2 can be brought into contact with each other only to the curved portion 220 having the higher strength among the locking springs 22A and 22B through the probe insertion holes 50a and 50b, respectively. Therefore, even if the probes P1 and P2 are strongly inserted into the probe insertion holes 50a and 50b, respectively, the locking springs 22A and 22B are unlikely to undergo plastic deformation. Therefore, in the switch device of the present embodiment, it is possible to check for poor continuity without deteriorating the functions of the locking springs 22A and 22B (the function of locking the electric wire).
　このようなチェック用の構造において、スイッチ装置は、第１受止め部５１Ａ及び５１Ｂを更に備えている（図２（Ａ）参照）。ここで、第１受止め部５１Ａは、プローブ用挿入穴５０ａに挿入されたプローブＰ１が湾曲部２２０に接触したとき（図５参照）に生じる当該プローブＰ１の押圧力を当該湾曲部２２０の背面側で受け止める。本実施形態では、第１受止め部５１Ａは、空間１０ａ内に嵌め込まれた保持部品２３に設けられている（図２（Ｂ）参照）。同様に、第１受止め部５１Ｂは、プローブ用挿入穴５０ｂに挿入されたプローブＰ２が湾曲部２２０に接触したときに生じる当該プローブＰ２の押圧力を当該湾曲部２２０の背面側で受け止める。本実施形態では、第１受止め部５１Ｂは、空間１０ｂ内に嵌め込まれた保持部品２３に設けられている。 In such a check structure, the switch device further includes first receiving portions 51A and 51B (see FIG. 2A). Here, the first receiving portion 51A applies the pressing force of the probe P1 generated when the probe P1 inserted into the probe insertion hole 50a comes into contact with the curved portion 220 (see FIG. 5) on the back surface of the curved portion 220. Take it on the side. In the present embodiment, the first receiving portion 51A is provided on the holding component 23 fitted in the space 10a (see FIG. 2B). Similarly, the first receiving portion 51B receives the pressing force of the probe P2 generated when the probe P2 inserted into the probe insertion hole 50b comes into contact with the curved portion 220 on the back surface side of the curved portion 220. In the present embodiment, the first receiving portion 51B is provided on the holding component 23 fitted in the space 10b.
　このような第１受止め部５１Ａ及び５１Ｂによれば、プローブＰ１及びＰ２をそれぞれ係止バネ２２Ａ及び２２Ｂの湾曲部２２０に接触させたときに、当該プローブＰ１及びＰ２の押圧力がそれぞれ、湾曲部２２０の背面側で第１受止め部５１Ａ及び５１Ｂによって受け止められる。よって、係止バネ２２Ａ及び２２Ｂの塑性変形を確実に防止できる。 According to the first receiving portions 51A and 51B, when the probes P1 and P2 are brought into contact with the curved portions 220 of the locking springs 22A and 22B, respectively, the pressing force of the probes P1 and P2 is curved, respectively. It is received by the first receiving portions 51A and 51B on the back side of the portion 220. Therefore, the plastic deformation of the locking springs 22A and 22B can be reliably prevented.
