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鎖錠ばねと、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鎖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（例えば、特許文献１参照）。   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. The lock spring that locks the electric wires and locks the electric wires at the same time to prevent them from coming off, and the release that is unlocked by the lock springs when operated with a screwdriver tool through the operation hole in the body It is comprised with the button (for example, refer patent document 1).

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があった。そこで、図３３に示すように電線Ｌ１が接続されていない状態ではコイルばねＨ３によって弾性付勢された表示体Ｈ２の一部が器体Ｈに設けた孔から突出しており、電線Ｌ１が接続されたときに電線Ｌ１（導体Ｌ１０）によりコイルばねＨ３のばね力に抗して表示体Ｈ２が押動され、表示体Ｈ２の一部が孔の中に退避することで電線の接続完了表示を行うものが提案されている。
特開平１１−１８５９０５号公報（段落００１４、図１） However, the above-described conventional quick connection terminal device has a problem of giving an uneasiness to the installer because it is not known from the outside whether or not the electric wire is securely connected. Therefore, as shown in FIG. 33, when the electric wire L1 is not connected, a part of the display body H2 elastically biased by the coil spring H3 protrudes from the hole provided in the vessel body H, and the electric wire L1 is connected. The display body H2 is pushed against the spring force of the coil spring H3 by the electric wire L1 (conductor L10), and a part of the display body H2 is retracted into the hole, thereby displaying the connection completion of the electric wire. Things have been proposed.
Japanese Patent Laid-Open No. 11-185905 (paragraph 0014, FIG. 1)

しかしながら上記従来の電線接続完了表示機構では、表示体Ｈ２とコイルばねＨ３の２部品を新たに追加するとともにこれらの部品を収納するスペースを器体に設ける必要があり、部品点数の増加や器体の設計変更等によるコストアップが生じるという問題があった。また上記従来機構は電線の接続完了表示を視覚的に行うものであるから、その表示部位が見えない状況下で施工する際には接続完了表示が確認できないものであった。   However, in the above-described conventional wire connection completion display mechanism, it is necessary to newly add two parts, the display body H2 and the coil spring H3, and to provide a space for housing these parts in the body, increasing the number of parts and the body. There was a problem that the cost would increase due to the design change. Further, since the conventional mechanism visually displays the connection completion of the electric wire, the connection completion display cannot be confirmed when construction is performed in a state where the display portion cannot be seen.

一方、器体１００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、解除レバー３０は縦溝１０４を通して連結部３４並びに操作部３１が器体１００の外に露出され、押動部３３が端子板１の鎖錠片４における受け部４ｃと対向し、端子板収納室１０２内に設けられた軸受け台１０３に軸部３２ａを載置することにより、軸部３２ａを支点に器具本体１の前後方向（図１における上下方向）に沿って回動自在に配設される。尚、図示は省略するが、端子板収納室１０２には互いに鏡像の関係となる２つの解除レバー３０が本体部３２を隣り合わせるように並べて配設される。   On the other hand, a vertical groove 104 communicating with the terminal plate storage chamber 102 is provided on the side surface of the container body 100, and the release lever 30 is exposed to the outside of the container body 100 through the vertical groove 104, and the connection portion 34 and the operation portion 31 are exposed. The pushing portion 33 is opposed to the receiving portion 4c of the locking piece 4 of the terminal plate 1 and the shaft portion 32a is placed on the bearing base 103 provided in the terminal plate storage chamber 102, thereby supporting the shaft portion 32a as a fulcrum. The instrument main body 1 is disposed so as to be rotatable along the front-rear direction (vertical direction in FIG. 1). Although not shown, two release levers 30 that are mirror images of each other are arranged in the terminal plate storage chamber 102 so that the main body portions 32 are adjacent to each other.

ところで、電線１１０が接続されていない状態においては、図１（ａ）に示すように係止部３７が端子板１の被係止部６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端子板１の受け部４ｃが押動部３４に押動されて鎖錠片４が接触片３から離れる向きに撓んだ状態にある。このとき鎖錠片４のばね力によって解除レバー３０が反操作方向（図１における反時計回り）に弾性付勢されるが、係止部３７が端子板１の被係止部６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。   By the way, when the electric wire 110 is not connected, as shown in FIG. 1A, the release lever 30 reaches the rotation position where the locking portion 37 is locked (latched) to the locked portion 6 of the terminal board 1. (Hereinafter, this rotational position is referred to as “initial position”). When the release lever 30 is in the initial position, the receiving portion 4 c of the terminal board 1 is pushed by the pushing portion 34 and the locking piece 4 is bent in a direction away from the contact piece 3. At this time, the release lever 30 is elastically biased in the counter-operation direction (counterclockwise in FIG. 1) by the spring force of the locking piece 4, but the locking portion 37 is locked to the locked portion 6 of the terminal plate 1. Therefore, the release lever 30 is held at the initial position.

そして、図１（ｂ）に示すように電線挿入孔１０１を通して電線１１０の導体１１１を接触片３と鎖錠片４との間に導入すると、挿通部５を通して導体１１１の先端が解除レバー３０の係止部３７に当接し、係止部３７を押し上げて係止部３７と被係止部６とのラッチ状態を解除する。すると、図１（ｃ）に示すように鎖錠片４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、鎖錠片４の鎖錠部４ａが導体１１１に食い込むことによって電線１１０が抜け止めされるとともに鎖錠片４のばね力によって導体１１１が接触片３に弾接する。さらに導体１１１は一対の押圧部３ａ，３ｂによって鎖錠片４の方へ押圧され、鎖錠部４ａと一対の押圧部３ａ，３ｂの押圧力が均衡して電線１１０が狭持される。また鎖錠片４のばね力で反操作方向に回動した解除レバー３０は、やがて操作部３１が器体１００表面に当たって停止するが、このとき操作部３１が器体１００表面に衝突することで音（衝突音）を発生する（図１（ｄ）参照）。   Then, when the conductor 111 of the electric wire 110 is introduced between the contact piece 3 and the locking piece 4 through the electric wire insertion hole 101 as shown in FIG. It abuts on the locking portion 37 and pushes up the locking portion 37 to release the latched state between the locking portion 37 and the locked portion 6. Then, as shown in FIG. 1C, the release lever 30 that has been elastically biased by the spring force of the locking piece 4 rotates in the counter-operation direction, and the locking portion 4 a of the locking piece 4 moves to the conductor 111. The electric wire 110 is prevented from coming off by biting in, and the conductor 111 elastically contacts the contact piece 3 by the spring force of the locking piece 4. Furthermore, the conductor 111 is pressed toward the locking piece 4 by the pair of pressing portions 3a and 3b, and the pressing force of the locking portion 4a and the pair of pressing portions 3a and 3b is balanced to hold the electric wire 110. In addition, the release lever 30 rotated in the counter-operation direction by the spring force of the locking piece 4 eventually stops when the operation unit 31 hits the surface of the body 100, but at this time, the operation unit 31 collides with the surface of the body 100. A sound (impact sound) is generated (see FIG. 1D).

一方、図１（ｄ）に示すように電線１１０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３２ａを支点にして解除レバー３０が接続時と反対方向（図１における時計回り）に回動し、押動部３３が端子板１の受け部４ｃを押圧して導体１１１に食い込んでいる鎖錠部４ａを導体１１１から離すように鎖錠片４を撓ませて電線１１０の引き抜きが可能となる。   On the other hand, as shown in FIG. 1D, if the operation unit 31 is pushed upward while the electric wire 110 is connected, the release lever 30 is in the direction opposite to that at the time of connection with the shaft portion 32a as a fulcrum (see FIG. 1), and the pushing portion 33 presses the receiving portion 4c of the terminal plate 1 to bend the locking piece 4 so that the locking portion 4a biting into the conductor 111 is separated from the conductor 111. Thus, the electric wire 110 can be pulled out.

而して本実施形態によれば、端子板１と電線１１０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表示を視覚的に確認することができるとともに、操作部３１が器体１００表面に衝突する際に発生する音（衝突音）によって聴覚的にも確認することができ、しかも、電線１１０の接続を解除するための解除レバー３０を電線１１０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。また本実施形態では、ラッチ手段を構成する係止部３７が解除レバー３０に設けられ、同じくラッチ手段を構成する被係止部６が端子板１に設けられるとともに、端子板１の鎖錠部４ａ（鎖錠片４）を付勢手段としているため、電線の接続完了表示機構の追加に伴う部品点数の増加を抑えることができるものである。さらに電線１１０が接続されていない状態（初期位置）において、解除レバー３０の押動部３４によって受け部４ｃとともに鎖錠部４ａが押し動かされて接触片３との間に隙間が形成されているため、電線１１０の導体１１１がより線の場合でも容易に接続できるという利点がある。尚、本実施形態では端子板１の一部（接触片３の先端部）を鎖錠片４から離れる向き（解除レバー３０側）に曲げ起こすことで被係止部６が設けられているので、係止部３７との係止代が十分に確保できるために解除レバー３０のラッチが確実に行える。   Thus, according to the present embodiment, when the connection between the terminal board 1 and the electric wire 110 is completed, the operation portion 31 of the release lever 30 moves to a position below the initial position, thereby visually displaying the electric wire connection completion indication. And can also be aurally confirmed by the sound (collision sound) generated when the operation unit 31 collides with the surface of the body 100, and for releasing the connection of the electric wire 110. By using the release lever 30 also as a connection completion display of the electric wire 110, an increase in the number of parts can be suppressed. In the present embodiment, the latching portion 37 constituting the latch means is provided on the release lever 30, and the latched portion 6 constituting the latch means is also provided on the terminal plate 1. Since the biasing means 4a (locking piece 4) is used, an increase in the number of parts associated with the addition of the wire connection completion display mechanism can be suppressed. Further, in a state where the electric wire 110 is not connected (initial position), the locking portion 4a is pushed and moved together with the receiving portion 4c by the pushing portion 34 of the release lever 30, and a gap is formed between the contact piece 3. Therefore, even when the conductor 111 of the electric wire 110 is a stranded wire, there is an advantage that it can be easily connected. In addition, in this embodiment, since the to-be-latched part 6 is provided by bending up a part (terminal part of the contact piece 3) of the terminal board 1 in the direction away from the locking piece 4 (release lever 30 side). Since the locking allowance with the locking portion 37 can be sufficiently secured, the release lever 30 can be reliably latched.

（実施形態２）
図５〜図１３を参照して本実施形態の速結端子装置を説明する。但し、実施形態１と共通の構成要素には同一の符号を付して図示並びに説明を適宜省略する。 (Embodiment 2)
The quick connection terminal device of this embodiment will be described with reference to FIGS. However, 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.

本実施形態における端子板１は、図５及び図６に示すように電線１１０の導入方向と交差する方向（図５における左右方向）における略中央と対向する位置に接触片３が配設されることにより、鎖錠部４ａの中央部分を除いた両端部分が受け部４ｃとなっている。   As shown in FIGS. 5 and 6, in the terminal plate 1 in the present embodiment, the contact piece 3 is disposed at a position facing substantially the center in a direction (left-right direction in FIG. 5) that intersects the introduction direction of the electric wire 110. Thus, both end portions excluding the central portion of the lock portion 4a serve as receiving portions 4c.

一方、本実施形態における解除レバー３０は、図７及び図８に示すように接触片３を挟んで押動部３３と対向する第２の押動部３８と、第２の押動部３８と操作部３１とを連結する第２の連結部３９と、第２の連結部３９の端縁より腕部３６と並行して突出するとともに第１の腕部３６の先端と連結された第２の腕部４０と、第１の腕部３６と第２の腕部４０の連結部分から接触片３に向かって突出する係止部３７とを具備している。但し、図７に示した解除レバー３０と図８に示した解除レバー３０とは互いに鏡像の関係にある。   On the other hand, as shown in FIGS. 7 and 8, the release lever 30 in the present embodiment includes a second pushing portion 38 that faces the pushing portion 33 with the contact piece 3 interposed therebetween, a second pushing portion 38, and the like. A second connecting portion 39 that connects the operating portion 31, and a second connecting portion that protrudes in parallel with the arm portion 36 from the edge of the second connecting portion 39 and that is connected to the tip of the first arm portion 36. The arm portion 40, and a locking portion 37 that protrudes from the connecting portion of the first arm portion 36 and the second arm portion 40 toward the contact piece 3 are provided. However, the release lever 30 shown in FIG. 7 and the release lever 30 shown in FIG. 8 are mirror images of each other.

そして、図５及び図９に示すように２つの接触片３，３の間の空間に主部３２が配置され、主部３２に設けられた押動部３３が内側の受け部４ｃと対向し、接触片３を挟んで外側に配置された第２の押動部３８が外側の受け部４ｃと対向する形で２つの解除レバー３０，３０が端子板１と組み合わされ、端子板１の被係止部６に係止部３７を係止した初期位置に保持される（図９参照）。   As shown in FIGS. 5 and 9, the main portion 32 is arranged in the space between the two contact pieces 3 and 3, and the pushing portion 33 provided in the main portion 32 faces the inner receiving portion 4c. The two release levers 30 and 30 are combined with the terminal plate 1 in such a manner that the second pushing portion 38 disposed outside the contact piece 3 faces the outer receiving portion 4c. The locking portion 6 is held at the initial position where the locking portion 37 is locked (see FIG. 9).

図１０は本実施形態の速結端子装置を電圧極側の電線を接続する端子部と接地極側の電線を接続する端子部と接地線を接続する端子部とに用いた配線器具（コンセント）の一例を示している。このコンセントＣは、接地極付きのコンセント口１０５が器体１００前面に長手方向に並設されており、各端子部毎に２つの解除レバー３０が器体１００の側面に露出している。尚、解除レバー３０に第２の連結部３９が追加されたことに伴い、器体１００側面には各端子部毎にそれぞれ２つの縦溝１０４が追加されている。   FIG. 10 shows a wiring device (outlet) in which the quick connection terminal device of the present embodiment is used for a terminal portion for connecting a voltage pole side electric wire, a terminal portion for connecting a ground pole side electric wire, and a terminal portion for connecting a ground wire. An example is shown. In the outlet C, an outlet port 105 with a ground electrode is provided in parallel in the longitudinal direction on the front surface of the body 100, and two release levers 30 are exposed on the side surface of the body 100 for each terminal portion. In addition, with the addition of the second connecting portion 39 to the release lever 30, two vertical grooves 104 are added to the side surface of the container 100 for each terminal portion.

而して本実施形態では、前記鎖錠部４ａの異なる場所、すなわち鎖錠片４の幅方向における鎖錠部４ａの中央部分を除いた両端部分（受け部４ｃ，４ｃ）を解除レバー３０の押動部３３並びに第２の押動部３８で同時に押し動かすようにしたから、実施形態１のように一つの場所（受け部４ｃ）を押し動かす場合に比較して鎖錠部４ａをバランスよく押し動かすことができるために鎖錠部４ａ（鎖錠片４）の歪みが抑制できるとともに、歪み分を考慮した余分な押圧をする必要がないから端子板１（鎖錠片４）の塑性変形の軽減が図れるという利点がある。尚、本実施形態では、図１１に示すように押動部３３及び連結部３４と第２の押動部３８及び連結部３９とで、鎖錠部４ａと端子板１（接触片３）が導体１１１を狭持する部位と電線挿入孔１０１との間で導体１１１の周囲を囲む囲み部を構成しているので、この囲み部によって導体１１１の位置ずれが矯正できて電線１１０を確実に接続することができる。また図１２及び図１３に示すように、第２の押動部３８に第２の主部４１及び軸部４１ａと第２の支持部４２を一体に設ければ、軸部３２ａ及び支持部３５が片側だけにしかない場合に比較して、２つの軸部３２ａ，４１ａと２つの支持部３５，４２とによって解除レバー３０を安定して回動させることができる。   Thus, in the present embodiment, different positions of the lock portion 4a, that is, both end portions (receiving portions 4c and 4c) excluding the central portion of the lock portion 4a in the width direction of the lock piece 4 are provided on the release lever 30. Since the pushing portion 33 and the second pushing portion 38 are simultaneously pushed and moved, the lock portion 4a is balanced in comparison with the case where one place (receiving portion 4c) is pushed and moved as in the first embodiment. Since it can be pushed and moved, distortion of the lock part 4a (locking piece 4) can be suppressed, and it is not necessary to apply extra pressure considering the distortion, so that the terminal plate 1 (locking piece 4) is plastically deformed. There is an advantage that can be reduced. In the present embodiment, as shown in FIG. 11, the locking portion 4 a and the terminal plate 1 (contact piece 3) are formed by the pressing portion 33 and the connecting portion 34 and the second pressing portion 38 and the connecting portion 39. Since the surrounding part surrounding the periphery of the conductor 111 is configured between the portion holding the conductor 111 and the wire insertion hole 101, the positional deviation of the conductor 111 can be corrected by this surrounding part and the electric wire 110 is securely connected. can do. As shown in FIGS. 12 and 13, if the second main portion 41, the shaft portion 41 a and the second support portion 42 are integrally provided in the second pushing portion 38, the shaft portion 32 a and the support portion 35 are provided. The release lever 30 can be stably rotated by the two shaft portions 32a and 41a and the two support portions 35 and 42, as compared with the case where is only on one side.

（実施形態３）
ところで、実施形態１，２では端子板１と他の導電部材（スイッチにおける接点やコンセントにおける刃受）との連結構造については具体的に説明しなかったが、通常は金属板を加工して端子板１と他の導電部材とを一体に形成することが望ましい。しかしながら、実施形態１，２では従来例における端子板と鎖錠ばねを一体に形成した関係上、他の導電部材を一体化する場合に非常に複雑な形状の金型が必要となり、かかる金型の複雑化を避けようとすれば端子板と他の導電部材とをかしめや溶接などの方法で連結しなければならない。 (Embodiment 3)
By the way, in Embodiments 1 and 2, the connection structure between the terminal plate 1 and other conductive members (contacts in switches and blade receptacles in outlets) has not been specifically described. It is desirable to integrally form the plate 1 and another conductive member. However, in Embodiments 1 and 2, since the terminal plate and the locking spring in the conventional example are integrally formed, a die having a very complicated shape is required when integrating other conductive members, and such a die is required. If it is going to avoid complication of this, a terminal board and another electrically-conductive member must be connected by methods, such as caulking and welding.

そこで本実施形態においては、図１４（ａ）及び図１５に示すように端子板１から鎖錠片４を取り除き、弾性を有する金属板によって略Ｕ字状に形成されたばね片１０ａと、ばね片１０ａの先端に設けられた鎖錠部１０ｂとを有する錠ばね１０で接続手段を構成することにより、端子板１の形状を簡素化している。弾性を有するとともに導電率が高い帯板状の金属板を曲げ加工することで略Ｕ字状のばね片１０ａが形成され、外側に折り曲げられたばね片１０ａの先端が鎖錠部１０ｂとなる。   Therefore, in the present embodiment, as shown in FIGS. 14A and 15, the locking piece 4 is removed from the terminal plate 1, and a spring piece 10a formed in a substantially U shape by an elastic metal plate, and the spring piece The shape of the terminal board 1 is simplified by comprising a connection means with the lock spring 10 which has the locking part 10b provided in the front-end | tip of 10a. A substantially U-shaped spring piece 10a is formed by bending a strip-shaped metal plate having elasticity and high conductivity, and the tip of the spring piece 10a bent outward becomes the lock portion 10b.

端子板１は、図１５に示すように主片２の端縁から接触片３と対向する向きに垂下された当接片７が鎖錠片４の代わりに設けられており、鎖錠部１０ｂと対向するばね片１０ａの平坦部を当接片７に当接する形で端子板１の内側に錠ばね１０が配置される。   As shown in FIG. 15, the terminal plate 1 is provided with a contact piece 7 suspended from the edge of the main piece 2 so as to face the contact piece 3, instead of the lock piece 4, and the lock portion 10b. The lock spring 10 is disposed inside the terminal plate 1 so that the flat portion of the spring piece 10a facing the contact piece 7 is in contact with the contact piece 7.

電線（導体）が接続された状態では、錠ばね１０の鎖錠部１０ｂが導体に食い込んで抜け止めするとともにばね片１０ａのばね力によってばね片１０ａの平坦部が端子板１の当接片７に押しつけられることで端子板１と錠ばね１０とが導通する。尚、電線が接続された状態においては錠ばね１０に電線の挿入向き（図１４（ａ）における上向き）の力がはたらいて錠ばね１０が移動する際にばね片１０ａの後端が端子板１の主片２に食らい付く虞がある。そこで、図１４（ｂ）に示すようにばね片１０ａの後端を折曲しておけば、主片２に対するばね片１０ａ後端の食らい付きが防止できて望ましい。   In a state where the electric wire (conductor) is connected, the lock portion 10b of the lock spring 10 bites into the conductor and prevents it from coming off, and the flat portion of the spring piece 10a is brought into contact with the contact piece 7 of the terminal plate 1 by the spring force of the spring piece 10a. The terminal plate 1 and the lock spring 10 are electrically connected. In the state where the electric wire is connected, the rear end of the spring piece 10a is connected to the terminal plate 1 when the force is applied to the lock spring 10 in the direction of inserting the electric wire (upward in FIG. 14A) and the lock spring 10 moves. There is a risk that the main piece 2 will bite. Therefore, if the rear end of the spring piece 10a is bent as shown in FIG. 14B, it is desirable to prevent the rear end of the spring piece 10a from biting against the main piece 2.

而して本実施形態では、端子板１から鎖錠片４を取り除いて錠ばね１０で接続手段を構成するようにしたので、実施形態１，２における端子板１に比較して金型の複雑化を抑えつつスイッチにおける接点板やコンセントにおける刃受のような他の導電部材を端子板１の当接片７に連結して一体化することができ、端子板１と他の導電部材をかしめや溶接などで結合する工程が不要になるという利点がある。   Thus, in the present embodiment, the locking piece 4 is removed from the terminal plate 1 and the connection means is configured by the lock spring 10, so that the mold is more complicated than the terminal plate 1 in the first and second embodiments. It is possible to connect and integrate the other conductive member such as the contact plate in the switch or the blade holder in the outlet with the contact piece 7 of the terminal plate 1 while suppressing the formation of the terminal plate 1. There is an advantage that a process of joining by welding or the like becomes unnecessary.

（実施形態４）
本実施形態は、実施形態３と同様に端子板１と錠ばね１０とで構成されるものであって、図１６に示すように錠ばね１０を取り付ける取付部８が端子板１の主片２に設けられている点に特徴がある。 (Embodiment 4)
The present embodiment is constituted by the terminal plate 1 and the lock spring 10 as in the third embodiment, and the mounting portion 8 to which the lock spring 10 is attached is the main piece 2 of the terminal plate 1 as shown in FIG. There is a feature in the point provided.

錠ばね１０は、ばね片１０ａの後端部が鎖錠部１０ｂに向かって湾曲し、その先から電線の導入方向に沿って突出する略Ｔ字形の取付片１０ｃが一体に形成されている。   The lock spring 10 is integrally formed with a substantially T-shaped attachment piece 10c whose rear end portion is bent toward the lock portion 10b and protrudes from the tip of the lock spring 10 along the electric wire introduction direction.

端子板１の主片２に設けられた取付部８は、錠ばね１０の取付片１０ｃが係止する係止溝８ａと、係止溝８ａよりも幅細であって挿通部５と係止溝８ａとを連通する連通溝８ｂとで構成される。   The mounting portion 8 provided on the main piece 2 of the terminal plate 1 has a locking groove 8a that the mounting piece 10c of the lock spring 10 locks, and is narrower than the locking groove 8a and locks with the insertion portion 5. The communication groove 8b communicates with the groove 8a.

次に端子板１に対する錠ばね１０の取付手順について説明する。まず端子板１に対して錠ばね１０を約９０度回転させた状態で連通溝８ｂ並びに挿通部５に取付片１０ｃを挿通し、取付片１０ｃの首の部分を連通溝８ｂを通して係止溝８ａまで移動させる（図１０（ｂ）参照）。そして、鎖錠部１０ｂが接触片３と対向する向きに錠ばね１０を回転すれば（図１０（ｃ）（ｄ）参照）、取付片１０ｃが係止溝８ａに係止されて端子板１の取付部８に錠ばね１０が取り付けられる。   Next, a procedure for attaching the lock spring 10 to the terminal plate 1 will be described. First, with the lock spring 10 rotated about 90 degrees with respect to the terminal plate 1, the attachment piece 10c is inserted into the communication groove 8b and the insertion portion 5, and the neck portion of the attachment piece 10c is passed through the communication groove 8b and the locking groove 8a. (Refer to FIG. 10B). Then, if the lock spring 10 is rotated in a direction in which the locking portion 10b faces the contact piece 3 (see FIGS. 10C and 10D), the attachment piece 10c is locked in the locking groove 8a and the terminal plate 1 is locked. A lock spring 10 is attached to the attachment portion 8.

而して本実施形態では、電線を接続した状態で錠ばね１０が上に押し上げられるとばね片１０ａと後端縁と主片２の下面が接触動通し、錠ばね１０が下に引き下げられると取付片１０ｃの下端縁と主片２の上面が接触導通するから、錠ばね１０と端子板１の当接片７との間だけでなく、取付部８と取付片１０ｃとの間においても端子板１と錠ばね１０とが通電することになって両者の接触信頼性が向上し、しかも、端子板１の主片２に錠ばね１０を容易に取り付けることができるという利点がある。但し、図１７に示すように端子板１の当接片７に取付部８を設けるようにしても同様の効果を奏する。   Thus, in this embodiment, when the lock spring 10 is pushed up with the electric wire connected, the spring piece 10a, the rear end edge, and the lower surface of the main piece 2 are brought into contact and moved, and the lock spring 10 is pulled down. Since the lower end edge of the mounting piece 10c and the upper surface of the main piece 2 are brought into contact with each other, not only between the lock spring 10 and the contact piece 7 of the terminal plate 1, but also between the mounting portion 8 and the mounting piece 10c. Since the plate 1 and the lock spring 10 are energized, the contact reliability between them is improved, and the lock spring 10 can be easily attached to the main piece 2 of the terminal plate 1. However, as shown in FIG. 17, the same effect can be obtained even if the mounting portion 8 is provided on the contact piece 7 of the terminal plate 1.

（実施形態５）
本実施形態は、実施形態３と同様に端子板１と錠ばね１０とで構成されるものであって、図１８に示すように錠ばね１０のばね片１０ａ後端部（平坦部）に、ばね片１０ａの撓み方向に撓み自在とした補助ばね片１０ｄが設けられている点に特徴がある。 (Embodiment 5)
This embodiment is composed of the terminal plate 1 and the lock spring 10 as in the third embodiment. As shown in FIG. 18, the spring piece 10a of the lock spring 10 has a rear end portion (flat portion). There is a feature in that an auxiliary spring piece 10d that can be freely bent in the bending direction of the spring piece 10a is provided.

補助ばね片１０ｄは、図１９に示すようにばね片１０ａの平坦部に逆Ｕ字形の溝を形成し、その溝の内側の部位を略Ｖ字形に折曲してなり、折曲された曲げ部１０ｅがばね片１０ａの平坦部よりも外側に突出している。そして、図１８に示すように端子板１の内側に錠ばね１０が組み込まれた状態では補助ばね片１０ｄが曲げ部１０ｅにおいて端子板１の当接片７と当接している。   The auxiliary spring piece 10d is formed by forming an inverted U-shaped groove in the flat part of the spring piece 10a as shown in FIG. 19, and bending the inner part of the groove into a substantially V-shape. The part 10e protrudes outside the flat part of the spring piece 10a. As shown in FIG. 18, when the lock spring 10 is incorporated inside the terminal plate 1, the auxiliary spring piece 10d is in contact with the contact piece 7 of the terminal plate 1 at the bent portion 10e.

而して、図２０（ａ）〜（ｃ）に示すように解除レバー３０若しくは電線１１０（導体１１１）によって錠ばね１０のばね片１０ａが撓められたときに補助ばね片１０ｄも同様に撓められ、ばね片１０ａと補助ばね片１０ｄの双方で荷重を受けているため、ばね片１０ａの湾曲した部分にかかる応力を補助ばね片１０ｄに分散することでばね片１０ａの塑性変形が抑制できる。   Thus, when the spring piece 10a of the lock spring 10 is bent by the release lever 30 or the electric wire 110 (conductor 111) as shown in FIGS. Since the load is received by both the spring piece 10a and the auxiliary spring piece 10d, the plastic deformation of the spring piece 10a can be suppressed by dispersing the stress applied to the curved portion of the spring piece 10a to the auxiliary spring piece 10d. .

（実施形態６）
ところで、解除レバー３０に設けた係止部３７を端子板１に設けた被係止部６に係止する実施形態１〜５の構成においては、電線１１０の接続を解除する際に解除レバー３０の係止部３７が導体１１１の先端に乗り上げなければならないから、その乗り上げの際に係止部３７の設けられた腕部３６を撓ませる必要があるが、腕部３６の形状や材質によっては十分な撓み量が確保できない場合には解除レバー３０の操作性が損なわれる虞がある。 (Embodiment 6)
By the way, in the structure of Embodiments 1-5 which latch the latching | locking part 37 provided in the release lever 30 to the to-be-latched part 6 provided in the terminal board 1, when releasing the connection of the electric wire 110, the release lever 30 is provided. Therefore, it is necessary to bend the arm portion 36 provided with the locking portion 37 at the time of riding, depending on the shape and material of the arm portion 36. If a sufficient amount of bending cannot be ensured, the operability of the release lever 30 may be impaired.

そこで本実施形態では、端子板１の被係止部６及び解除レバー３０の係止部３７の代わりにラッチばね２０を用いて解除レバー３０を初期位置にラッチする点に特徴がある。このラッチばね２０は、図２１及び図２２に示すように略Ｚ字状の一対のばね片２１と、一対のばね片２１の先端（図２１における上端）同士を連結する連結片２２と、ばね片２１の後端部（図２１における下端部）から下方へ切り起こされて導体１１１の先端部に当接する当接片２３と、ばね片２１の後端縁から下方へ垂下されて解除レバー３０が係止する被係止片２４とが、金属製の板ばね材を打ち抜き及び曲げ加工することによって一体に形成されている。そして、図２３に示すように当接片２３を端子板１の挿通部５に挿通するとともに主片２に貫設された孔９に被係止片２４を挿通する形で、主片２を挟んで電線の導入方向において電線挿入孔（図示せず）と対向する位置（図２３においては主片１の上側）にラッチばね２０が配設される。このときばね片２１の先端部（図２３における上端部）は器体（図示せず）の内壁に当たって支持されている。   Therefore, the present embodiment is characterized in that the release lever 30 is latched at the initial position by using the latch spring 20 instead of the locked portion 6 of the terminal board 1 and the locking portion 37 of the release lever 30. As shown in FIGS. 21 and 22, the latch spring 20 includes a pair of substantially Z-shaped spring pieces 21, a connecting piece 22 that connects the tips (upper ends in FIG. 21) of the pair of spring pieces 21, and a spring. A contact piece 23 cut and raised from the rear end portion (lower end portion in FIG. 21) of the piece 21 to come into contact with the front end portion of the conductor 111, and a release lever 30 hanging downward from the rear end edge of the spring piece 21. The locked piece 24 that is locked is integrally formed by punching and bending a metal leaf spring material. Then, as shown in FIG. 23, the abutment piece 23 is inserted into the insertion portion 5 of the terminal plate 1 and the main piece 2 is inserted into the hole 9 penetrating the main piece 2. A latch spring 20 is disposed at a position (on the upper side of the main piece 1 in FIG. 23) facing the electric wire insertion hole (not shown) in the direction of introducing the electric wire. At this time, the tip end portion (the upper end portion in FIG. 23) of the spring piece 21 hits the inner wall of the container (not shown) and is supported.

一方本実施形態における解除レバー３０は、図２１及び図２４に示すように、図１２及び図１３に示した実施形態２の解除レバー３０において腕部３６，４０並びに係止部３７の代わりに、２つの支持部３５，４２の先端部分を連結するとともにラッチばね２０の被係止片２４に係止（ラッチ）する連結係止部４３を具備している。但し、図２１に示した２つの解除レバー３０は互いに鏡像の関係にある。また端子板１は主片２に孔９が貫設されている点以外は実施形態２のものと共通である。   On the other hand, as shown in FIGS. 21 and 24, the release lever 30 in the present embodiment is replaced with the release lever 30 of the second embodiment shown in FIGS. 12 and 13, instead of the arm portions 36 and 40 and the locking portion 37. A connection locking portion 43 is provided for connecting the tip portions of the two support portions 35 and 42 and locking (latching) the locking spring 24 to the locked piece 24 of the latch spring 20. However, the two release levers 30 shown in FIG. 21 are mirror images of each other. The terminal plate 1 is the same as that of the second embodiment except that the hole 9 is formed through the main piece 2.

そして、図２５（ａ）に示すように２つの接触片３，３の間の空間に主部３２が配置され、主部３２に設けられた押動部３３が鎖錠部４ａの内側と対向し、接触片３を挟んで外側に配置された第２の押動部３８が鎖錠部４ａの外側と対向する形で２つの解除レバー３０，３０が端子板１と組み合わされる。この状態から操作部３１を押し上げるようにして解除レバー３０を回動すれば、連結係止部４３が被係止片２４を押圧することでばね片２１が上方へ撓み、やがて連結係止部４３が被係止片２４を乗り越えるとばね片２１が復元することで被係止片２４に連結係止部４３が係止され、２つの押動部３３，３８が鎖錠部４ａから受ける弾性付勢力に抗して解除レバー３０が初期位置に保持される（図２５（ｂ）参照）。   And the main part 32 is arrange | positioned in the space between the two contact pieces 3 and 3, as shown to Fig.25 (a), and the pushing part 33 provided in the main part 32 opposes the inner side of the locking part 4a. Then, the two release levers 30 and 30 are combined with the terminal plate 1 in such a manner that the second pushing portion 38 arranged on the outside with the contact piece 3 interposed therebetween faces the outside of the locking portion 4a. If the release lever 30 is rotated so as to push up the operating portion 31 from this state, the connection locking portion 43 presses the locked piece 24 and the spring piece 21 is bent upward, and eventually the connection locking portion 43. As the spring piece 21 is restored, the coupling locking portion 43 is locked to the locked piece 24 and the two pushing portions 33 and 38 are elastically received from the locking portion 4a. The release lever 30 is held at the initial position against the force (see FIG. 25B).

そして、図２５（ｃ）に示すように電線挿入孔（図示せず）を通して電線１１０の導体１１１を接触片３と鎖錠片４との間に導入すると、挿通部５を通して導体１１１の先端がラッチばね２０の当接片２３に当接し、当接片２３が押し上げられてばね片２１が上方へ撓むため、被係止片２４と連結係止部４３とのラッチ状態が解除される。すると鎖錠片４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、鎖錠片４の鎖錠部４ａが導体１１１に食い込むことによって電線１１０が抜け止めされるとともに鎖錠片４のばね力によって導体１１１が接触片３に弾接する。また鎖錠片４のばね力で反操作方向に回動した解除レバー３０の操作部３１が器体表面に衝突することで音（衝突音）が発生する。また、図２５（ｃ）に示すように電線１１０が接続された状態ではラッチばね２０の被係止片２４が孔９の外に退出しているから、電線１１０の接続を解除する際にラッチばね２０が解除レバー３０の邪魔になることがなく解除レバー３０の操作性が向上するものである。   When the conductor 111 of the electric wire 110 is introduced between the contact piece 3 and the locking piece 4 through the electric wire insertion hole (not shown) as shown in FIG. 25 (c), the tip of the conductor 111 is inserted through the insertion portion 5. Since the abutting piece 23 abuts on the abutting piece 23 of the latch spring 20 and the abutting piece 23 is pushed up and the spring piece 21 bends upward, the latched state of the latched piece 24 and the coupling latching portion 43 is released. Then, the release lever 30 that has been elastically biased by the spring force of the locking piece 4 rotates in the counter-operation direction, and the locking portion 4a of the locking piece 4 bites into the conductor 111, thereby preventing the electric wire 110 from coming off. At the same time, the conductor 111 elastically contacts the contact piece 3 by the spring force of the locking piece 4. In addition, a sound (collision sound) is generated when the operation portion 31 of the release lever 30 rotated in the counter-operation direction by the spring force of the locking piece 4 collides with the body surface. Further, as shown in FIG. 25 (c), when the electric wire 110 is connected, the latched piece 24 of the latch spring 20 is retracted out of the hole 9, so that the latch is performed when the electric wire 110 is disconnected. The operability of the release lever 30 is improved without the spring 20 interfering with the release lever 30.

尚、図２６に示すように、実施形態５と同様に端子板１と２つの錠ばね１０との３部品で構成しても構わない。このとき、解除レバー３０が操作されたときに解除レバー３０を逃げるために、錠ばね１０のばね片１０ａの後端を切り欠いて逃がし部１０ｆを設けておけば、解除レバー３０に対する寸法の制約が緩和できて解除レバー３０の強度が向上できる。   In addition, as shown in FIG. 26, you may comprise by 3 components of the terminal board 1 and the two lock springs 10 similarly to Embodiment 5. FIG. At this time, in order to escape the release lever 30 when the release lever 30 is operated, if the release portion 10f is provided by cutting out the rear end of the spring piece 10a of the lock spring 10, the size of the release lever 30 is limited. Can be relaxed and the strength of the release lever 30 can be improved.

（実施形態７）
ところで、実施形態２で例示したような埋込型の配線器具の端子部に本発明に係る速結端子装置が用いられる場合、器体１００表面に露出している解除レバー３０の操作部３１に電線が当たることで解除レバー３０が不用意に回動してしまうことが考えられる。 (Embodiment 7)
By the way, when the quick connection terminal device according to the present invention is used for the terminal portion of the embedded wiring apparatus as exemplified in the second embodiment, the operation portion 31 of the release lever 30 exposed on the surface of the container body 100 is used. It is conceivable that the release lever 30 is inadvertently rotated by hitting the electric wire.

本実施形態は電線が当たって解除レバー３０が不用意に回動することを防止するため、図２７に示すように器体１００の表面における解除レバー３０の操作部３１が露出する部位の周囲に操作部３１の操作方向以外の方向から操作部３１の周囲を囲む壁１０６が設けられている点に特徴がある。但し、実施形態１と共通の構成要素には同一の符号を付して図示並びに説明を適宜省略する。   In the present embodiment, in order to prevent the release lever 30 from being inadvertently rotated by hitting an electric wire, as shown in FIG. 27, around the portion where the operation portion 31 of the release lever 30 is exposed on the surface of the body 100. A feature is that a wall 106 surrounding the operation unit 31 from a direction other than the operation direction of the operation unit 31 is provided. However, 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.

壁１０６は器体１００の側面から突設され、器体１００を側面から見たときに解除レバー３０の四周を覆う角筒状に形成されている。また壁１０６の底面には解除レバー３０のラッチ状態が解除されているときに操作部３１が視認可能な窓孔１０６ａが設けられている。尚、図２７においては器体１００を構成するボディ１００ａとカバー（図示せず）のうちでボディ１００ａのみを図示している。   The wall 106 protrudes from the side surface of the container body 100 and is formed in a rectangular tube shape covering the four circumferences of the release lever 30 when the container body 100 is viewed from the side surface. Further, a window hole 106a is provided on the bottom surface of the wall 106 so that the operation unit 31 can be visually recognized when the release lever 30 is in a latched state. In FIG. 27, only the body 100a is illustrated among the body 100a and the cover (not shown) constituting the container 100.

本実施形態における解除レバー３０は、図２７に示すように操作部３１から操作方向へ突出する平板状のつまみ４４が設けられている点を除けば、実施形態２のものと共通である。   The release lever 30 in the present embodiment is the same as that of the second embodiment except that a flat tab 44 protruding in the operation direction from the operation unit 31 is provided as shown in FIG.

而して、図２８（ａ）に示すように電線挿入孔１０１を通して電線１１０の導体１１１を接触片３と鎖錠片４との間に導入すると、挿通部５を通して導体１１１の先端が解除レバー３０の係止部３７に当接し、係止部３７を押し上げて係止部３７と被係止部６とのラッチ状態を解除すれば、図２８（ｂ）に示すように鎖錠片４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、鎖錠片４の鎖錠部４ａが導体１１１に食い込むことによって電線１１０が抜け止めされるとともに鎖錠片４のばね力によって導体１１１が接触片３に弾接する。また鎖錠片４のばね力で反操作方向に回動した解除レバー３０の操作部３１が器体１００表面に衝突することで音（衝突音）を発生する。さらに、解除レバー３０が初期位置にあるときは壁１０６の窓孔１０６ａから操作部３１を視認することはできないが、電線の接続が完了して操作部３１が壁１０６の底面まで降りた状態では窓孔１０６ａを通して操作部３１が視認できるため、電線の接続完了表示が窓孔１０６ａを通しても視覚的に確認できる。尚、電線の接続を解除する際、つまみ４４を持って手前に引っ張れば、壁１０６に邪魔されずに操作部３１を操作することができて解除レバー３０の操作性が向上するものである（図２８（ｃ）参照）。   Thus, when the conductor 111 of the electric wire 110 is introduced between the contact piece 3 and the locking piece 4 through the electric wire insertion hole 101 as shown in FIG. If the latching state of the latching part 37 and the latched part 6 is released by abutting on the latching part 37 of 30 and pushing up the latching part 37, the locking piece 4 of FIG. The release lever 30 that has been elastically biased by the spring force rotates in the counter-operation direction, and the lock portion 4a of the lock piece 4 bites into the conductor 111, thereby preventing the electric wire 110 from coming off and the lock piece 4 of the lock piece 4. The conductor 111 elastically contacts the contact piece 3 by the spring force. Further, when the operation portion 31 of the release lever 30 rotated in the counter-operation direction by the spring force of the locking piece 4 collides with the surface of the container 100, a sound (collision sound) is generated. Further, when the release lever 30 is in the initial position, the operation unit 31 cannot be visually recognized from the window hole 106a of the wall 106. However, in the state where the connection of the electric wire is completed and the operation unit 31 is lowered to the bottom surface of the wall 106. Since the operation part 31 can be visually recognized through the window hole 106a, the electric wire connection completion display can be visually confirmed through the window hole 106a. When releasing the connection of the electric wire, if the handle 44 is pulled to the front, the operation unit 31 can be operated without being obstructed by the wall 106, and the operability of the release lever 30 is improved ( FIG. 28 (c)).

（実施形態８）
本実施形態は、図２９に示すように器体１００の表面における解除レバー３０の操作部３１が露出する部位の周囲に、操作部３１の周囲を覆うとともに操作部３１を操作する工具が挿入される操作窓１０７ａが設けられた囲い体１０７を備えた点に特徴がある。尚、本実施形態における解除レバー３０は、図３０に示すように操作部３１の底面（操作窓１０７ａと対向する面）が平坦に形成されている点を除けば、実施形態２のものと共通である。 (Embodiment 8)
In the present embodiment, as shown in FIG. 29, a tool that covers the periphery of the operation unit 31 and operates the operation unit 31 is inserted around a portion of the surface of the body 100 where the operation unit 31 of the release lever 30 is exposed. It is characterized in that it includes an enclosure 107 provided with an operation window 107a. The release lever 30 in this embodiment is the same as that in the second embodiment except that the bottom surface of the operation unit 31 (the surface facing the operation window 107a) is formed flat as shown in FIG. It is.

囲い体１０７は器体１００と一体に形成された箱状であって、図３１に示すようにその内部には解除レバー３０の操作部３１が移動するためのスペースが設けられている。   The enclosure 107 has a box shape formed integrally with the container 100, and as shown in FIG. 31, a space for moving the operation portion 31 of the release lever 30 is provided therein.

而して、図３１（ａ）に示すように解除レバー３０が初期位置にある状態において、図３１（ｂ）に示すように電線挿入孔１０１を通して電線１１０の導体１１１を接触片３と鎖錠片４との間に導入すると、挿通部５を通して導体１１１の先端が解除レバー３０の係止部３７に当接し、係止部３７を押し上げて係止部３７と被係止部６とのラッチ状態が解除される。すると、図３１（ｃ）に示すように鎖錠片４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、鎖錠片４の鎖錠部４ａが導体１１１に食い込むことによって電線１１０が抜け止めされるとともに鎖錠片４のばね力によって導体１１１が接触片３に弾接する。また鎖錠片４のばね力で反操作方向に回動した解除レバー３０の操作部３１が器体１００表面に衝突することで音（衝突音）を発生する。さらに、解除レバー３０が初期位置にあるときは囲い体１０７の操作窓１０７ａから操作部３１を視認することはできないが、電線の接続が完了して操作部３１が囲い体１０７の底面まで降りた状態では操作窓１０７ａを通して操作部３１が視認できるため、電線の接続完了表示が操作窓１０７ａを通しても視覚的に確認できる。   Thus, in the state where the release lever 30 is in the initial position as shown in FIG. 31A, the conductor 111 of the electric wire 110 is locked with the contact piece 3 through the electric wire insertion hole 101 as shown in FIG. When introduced between the two pieces 4, the leading end of the conductor 111 abuts on the engaging portion 37 of the release lever 30 through the insertion portion 5, and the engaging portion 37 is pushed up to latch the engaging portion 37 and the engaged portion 6. The state is released. Then, as shown in FIG. 31 (c), the release lever 30 that has been elastically biased by the spring force of the locking piece 4 rotates in the counter-operation direction, and the locking portion 4 a of the locking piece 4 moves to the conductor 111. The electric wire 110 is prevented from coming off by biting in, and the conductor 111 elastically contacts the contact piece 3 by the spring force of the locking piece 4. Further, when the operation portion 31 of the release lever 30 rotated in the counter-operation direction by the spring force of the locking piece 4 collides with the surface of the container 100, a sound (collision sound) is generated. Further, when the release lever 30 is in the initial position, the operation unit 31 cannot be viewed from the operation window 107a of the enclosure 107, but the connection of the electric wire is completed and the operation unit 31 descends to the bottom surface of the enclosure 107. In the state, since the operation unit 31 can be visually recognized through the operation window 107a, the wire connection completion display can be visually confirmed through the operation window 107a.

一方、図３１（ｄ）に示すように電線１１０が接続された状態で操作窓１０７ａから挿入した工具１２０で操作部３１を上方へ押し上げるように操作すれば、軸部３２ａを支点にして解除レバー３０が接続時と反対方向（図３１における反時計回り）に回動し、押動部３３，３８が端子板１の受け部４ｃを押圧して導体１１１に食い込んでいる鎖錠部４ａを導体１１１から離すように鎖錠片４を撓ませて電線１１０の引き抜きが可能となる。   On the other hand, as shown in FIG. 31 (d), if the operation unit 31 is pushed upward with the tool 120 inserted from the operation window 107a in a state where the electric wire 110 is connected, the release lever with the shaft portion 32a as a fulcrum. 30 rotates in the opposite direction to the time of connection (counterclockwise in FIG. 31), and the pushing portions 33 and 38 push the receiving portion 4c of the terminal plate 1 to cut the locking portion 4a that bites into the conductor 111 into the conductor. The lock piece 4 is bent so as to be separated from the wire 111 and the electric wire 110 can be pulled out.

而して本実施形態によれば、操作部３１を囲い体１０７で覆うことにより解除レバー３０が不用意に操作されることがなく、しかも、囲い体１０７に設けられた操作窓１０７ａに挿入した工具１２０で操作部３１を操作して解除レバー３０を回動すれば電線の接続を容易に解除することができる。また解除レバー３０の操作部３１における操作窓１０７ａと対向する面を平坦面としているから、工具１２０による操作部３１の操作が容易になるという利点がある。   Thus, according to the present embodiment, the release lever 30 is not inadvertently operated by covering the operation unit 31 with the enclosure 107, and is inserted into the operation window 107 a provided in the enclosure 107. If the operation part 31 is operated with the tool 120 and the release lever 30 is rotated, the connection of the electric wire can be easily released. Further, since the surface of the operation portion 31 of the release lever 30 that faces the operation window 107a is a flat surface, there is an advantage that the operation of the operation portion 31 by the tool 120 becomes easy.

尚、図３２に示すように囲い体１０７を器体１００の表面における解除レバー３０の操作部３１が露出する部位の周囲に着脱自在に取り付けられる構成とすれば、操作部３１の操作に工具１２０を使うか手動で行うかが選択できる。囲い体１０７は全体が略コ字状に形成され、その両端には略Ｔ字形の係合部１０７ｂがそれぞれ突設されている。そして、器体１００表面に沿って囲い体１０７を平行移動することにより、これら一対の係合部１０７ｂを器体１００に設けられた溝状の被係合部１０８に係合することで囲い体１０７が器体１００に着脱自在に取り付けられるものである。   As shown in FIG. 32, if the enclosure 107 is configured to be detachably attached around the portion of the surface of the body 100 where the operation portion 31 of the release lever 30 is exposed, the tool 120 can be used to operate the operation portion 31. You can choose to use or manually. The entire enclosure 107 is formed in a substantially U-shape, and approximately T-shaped engaging portions 107b are respectively provided at both ends thereof. Then, by moving the enclosure 107 in parallel along the surface of the container body 100, the pair of engaging portions 107 b are engaged with the groove-like engaged portions 108 provided in the container body 100, thereby enclosing the enclosure body. 107 is detachably attached to the body 100.
