Description

本発明は、電線が接続される接続機器に関する。 The present invention relates to a connecting device to which electric wires are connected.

従来、制御盤等において電線が接続される接続機器として、いわゆるプッシュイン式の接続機器が利用されている。当該接続機器では、ケースの挿入穴に電線が差し込まれると、ケース内に設けられた板バネにより当該電線が導通端子に押し付けられて電気的に接続される。 Conventionally, so-called push-in type connection devices have been used as connection devices to which electric wires are connected in control panels and the like. In this connection device, when an electric wire is inserted into the insertion hole of the case, the electric wire is pressed against the conduction terminal by a leaf spring provided in the case and electrically connected.

例えば、特許文献１および特許文献２では、ハウジングに対して進退可能な棒状の操作要素を設け、当該操作要素をドライバー等でハウジング内に押し込むことにより、ハウジング内の板バネを弾性変形させて導通端子から離間させる。そして、板バネが導通端子から離間したオープン状態を維持しつつ、板バネと導通端子との間に電線を挿入する。その後、操作要素の押し込みを解除することにより、板バネが弾性復帰して電線を導通端子との間で挟持する。 For example, in Patent Document 1 and Patent Document 2, a rod-shaped operating element that can move forward and backward with respect to the housing is provided, and by pushing the operating element into the housing with a screwdriver etc., a leaf spring in the housing is elastically deformed and conduction is established. Separate it from the terminal. Then, while maintaining the open state in which the leaf spring is separated from the conduction terminal, an electric wire is inserted between the leaf spring and the conduction terminal. Thereafter, by releasing the push-in of the operating element, the leaf spring elastically returns to clamp the electric wire between it and the conduction terminal.

しかしながら、特許文献１および特許文献２の接続機器では、上述のオープン状態を維持するためには、一方の手でドライバー等を比較的強い力で押し込んだ状態で維持する必要があり、接続機器の操作性があまり高くない。 However, in the connected devices of Patent Document 1 and Patent Document 2, in order to maintain the above-mentioned open state, it is necessary to maintain the state in which a screwdriver etc. is pushed in with a relatively strong force with one hand, and the connected device The operability is not very high.

そこで、特許文献３では、操作部をケース内に押し込んだ状態で係止することにより、ドライバー等をケースから抜いて操作部に対する押圧力を解除してもオープン状態を維持することができる技術が提案されている。 Therefore, Patent Document 3 discloses a technology that can maintain the open state even if a screwdriver or the like is removed from the case and the pressing force on the operating section is released by locking the operating section while it is pushed into the case. Proposed.

特許第６２２４８３６号公報Patent No. 6224836 米国特許第９９０５９４３号明細書US Patent No. 9905943 特開２０１８－１１６７７３号公報Japanese Patent Application Publication No. 2018-116773

ところで、特許文献３の接続機器では、ケースに係止された操作部を元の位置に戻して弾性部材と導通端子との間に電線を挟持させるために、ドライバー等をケース内に再度挿入し、操作部の位置を変更してケースとの係止を解除する必要がある。すなわち、接続機器に対する電線の接続のために、ドライバー等をケース内に２回挿入することが必要になり、接続機器の操作手順が複雑化する可能性がある。このような接続機器を操作する現場では、接続機器の操作性向上を求める声と、操作手順の簡素化を求める声との双方が存在する。 By the way, in the connection device of Patent Document 3, in order to return the operation part that is locked to the case to its original position and to sandwich the electric wire between the elastic member and the conduction terminal, a screwdriver or the like must be reinserted into the case. , it is necessary to change the position of the operating part to release the lock from the case. That is, it becomes necessary to insert a screwdriver or the like into the case twice in order to connect the electric wire to the connected device, which may complicate the operation procedure for the connected device. In the field where such connected devices are operated, there are both demands for improved operability of the connected devices and demands for simplified operating procedures.

本発明は、上記課題に鑑みなされたものであり、操作部を押し込んだ状態で維持する力を低減することを目的としている。 The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to reduce the force required to maintain the operating section in a depressed state.

図１は、本発明の第１の実施の形態に係る接続機器１の斜視図である。図２は、接続機器１の断面図である。図３は、接続機器１を図２中のＩＩＩ－ＩＩＩの位置にて切断した断面図である。図４は、接続機器１の分解斜視図である。接続機器１は、電線９１が接続されるプッシュイン式の接続機器である。接続機器１は、例えば、制御盤等の端子台に利用される。図１では、接続機器１の手前側に薄板状のエンドプレート１１が取り付けられている。また、図１では、複数の接続機器１が連結された状態を二点鎖線にて示す。図２ないし図４では、電線９１が接続機器１に挿入されていない状態を示す。図２では、断面よりも奥側の構成についても併せて図示している。 FIG. 1 is a perspective view of a connecting device 1 according to a first embodiment of the present invention. FIG. 2 is a sectional view of the connected device 1. As shown in FIG. FIG. 3 is a cross-sectional view of the connecting device 1 taken along the line III--III in FIG. 2. As shown in FIG. FIG. 4 is an exploded perspective view of the connected device 1. The connecting device 1 is a push-in type connecting device to which an electric wire 91 is connected. The connection device 1 is used, for example, as a terminal block for a control panel or the like. In FIG. 1, a thin end plate 11 is attached to the front side of the connecting device 1. As shown in FIG. Moreover, in FIG. 1, a state in which a plurality of connected devices 1 are connected is shown by a two-dot chain line. 2 to 4 show a state in which the electric wire 91 is not inserted into the connecting device 1. In FIG. 2, the configuration on the back side of the cross section is also illustrated.

以下の説明では、図２中の上下方向および左右方向を、単に「上下方向」および「左右方向」とも呼ぶ。また、図２において紙面に垂直な方向を「厚さ方向」とも呼ぶ。図２は、接続機器１の厚さ方向の略中央における断面を示す。当該上下方向、左右方向および厚さ方向は、接続機器１が使用される際の取付方向とは必ずしも一致する必要はない。また、当該上下方向は、重力方向とも必ずしも一致する必要はない。 In the following description, the up-down direction and the left-right direction in FIG. 2 are also simply referred to as the "up-down direction" and the "left-right direction." Further, in FIG. 2, the direction perpendicular to the paper surface is also referred to as the "thickness direction." FIG. 2 shows a cross section at approximately the center of the connecting device 1 in the thickness direction. The vertical direction, horizontal direction, and thickness direction do not necessarily need to coincide with the mounting direction when the connecting device 1 is used. Furthermore, the vertical direction does not necessarily need to coincide with the direction of gravity.

接続機器１は、ケース２と、端子部３と、弾性部材４と、操作部５とを備える。ケース２は、端子部３、弾性部材４および操作部５を内部に収容する。ケース２は、例えば樹脂製である。図２に示す例では、ケース２には、それぞれに電線が挿入可能な２つの挿入穴２１が設けられる。また、ケース２の内部には、２つの端子部３と、２つの弾性部材４と、２つの操作部５とが収容されている。換言すれば、接続機器１は、２セットの端子部３、弾性部材４および操作部５を備える。なお、接続機器１は、１セットまたは３セット以上の端子部３、弾性部材４および操作部５を備えていてもよい。 The connecting device 1 includes a case 2, a terminal section 3, an elastic member 4, and an operating section 5. The case 2 accommodates the terminal portion 3, the elastic member 4, and the operating portion 5 therein. The case 2 is made of resin, for example. In the example shown in FIG. 2, the case 2 is provided with two insertion holes 21 into which electric wires can be inserted. Further, inside the case 2, two terminal parts 3, two elastic members 4, and two operating parts 5 are housed. In other words, the connecting device 1 includes two sets of terminal portions 3, elastic members 4, and operating portions 5. Note that the connecting device 1 may include one set or three or more sets of the terminal section 3, the elastic member 4, and the operation section 5.

端子部３、弾性部材４および操作部５の各セットは、挿入穴２１に対応して配置される。２セットの端子部３、弾性部材４および操作部５は、形状および大きさ等は互いに同じであり、左右反対向きに配置される。図２中の右側の挿入穴２１に注目すると、端子部３は、挿入穴２１の下端部の右側に位置し、挿入穴２１の下端部から下方に延びる。弾性部材４は、挿入穴２１の下端部から左側へと延び、さらに下方へと延びる。操作部５は、挿入穴２１の左側において、弾性部材４の上側に配置される。 Each set of the terminal portion 3, the elastic member 4, and the operating portion 5 is arranged corresponding to the insertion hole 21. The two sets of terminal portions 3, elastic members 4, and operating portions 5 have the same shape, size, etc., and are arranged in left-right opposite directions. Focusing on the insertion hole 21 on the right side in FIG. 2, the terminal portion 3 is located on the right side of the lower end of the insertion hole 21 and extends downward from the lower end of the insertion hole 21. The elastic member 4 extends from the lower end of the insertion hole 21 to the left side and further extends downward. The operating section 5 is arranged above the elastic member 4 on the left side of the insertion hole 21 .

端子部３は、ケース２に固定された導電性の部材である。端子部３は、例えば金属製である。図２中の右側の端子部３は、図２中の左側の端子部３と電気的に接続されている。図２ないし図４に示す例では、当該２つの端子部３は一繋がりの部材である。具体的には、２つの端子部３の下端部が、左右方向に延びる導電性の端子接続部３２により接続されている。 The terminal portion 3 is a conductive member fixed to the case 2. The terminal portion 3 is made of metal, for example. The terminal portion 3 on the right side in FIG. 2 is electrically connected to the terminal portion 3 on the left side in FIG. In the examples shown in FIGS. 2 to 4, the two terminal portions 3 are a continuous member. Specifically, the lower end portions of the two terminal portions 3 are connected by a conductive terminal connecting portion 32 extending in the left-right direction.

弾性部材４は、ケース２に取り付けられた弾性変形可能な部材である。図２ないし図４に示す例では、弾性部材４は、略帯状の板バネである。弾性部材４は、例えば金属製である。弾性部材４は、導電材料により形成されてもよく、樹脂等の絶縁材料により形成されてもよい。弾性部材４は、例えば、長手方向の中央部４１にて略Ｌ字状、略Ｖ字状または略Ｕ字状に折り曲げられた形状を有する。弾性部材４は、中央部４１をケース２により挟まれることにより、両端部を略下側に向けた状態でケース２に取り付けられる。以下の説明では、ケース２のうち中央部４１に下側から接する部位２２を、「支持部２２」と呼ぶ。支持部２２は、弾性部材４の中央部４１から略下方に延びる。 The elastic member 4 is an elastically deformable member attached to the case 2. In the example shown in FIGS. 2 to 4, the elastic member 4 is a substantially belt-shaped leaf spring. The elastic member 4 is made of metal, for example. The elastic member 4 may be formed of a conductive material or an insulating material such as resin. The elastic member 4 has, for example, a shape bent at a central portion 41 in the longitudinal direction into a substantially L-shape, a substantially V-shape, or a substantially U-shape. The elastic member 4 is attached to the case 2 with the center portion 41 sandwiched between the case 2 and both ends facing substantially downward. In the following description, the portion 22 of the case 2 that contacts the central portion 41 from below will be referred to as the "support portion 22." The support portion 22 extends substantially downward from the center portion 41 of the elastic member 4 .

図２中の右側の弾性部材４に注目すると、当該弾性部材４のうち、中央部４１から支持部２２の左側に延びる部位４２は、支持部２２とケース２の他の部位との間に挟まれることにより、ケース２に固定されている。また、当該弾性部材４のうち、中央部４１から支持部２２の右側に延びる部位４３は、上下方向に延びる端子部３に接触している。弾性部材４の部位４３は、操作部５により下方に押されることにより、支持部２２の上端部を支点として弾性変形して下向きに撓む。また、当該部位４３に対する下向きの押圧力がなくなると、部位４３は復元力により元の状態に戻る（すなわち、弾性復帰する）。以下の説明では、弾性部材４の部位４２および部位４３をそれぞれ、「固定部４２」および「可動部４３」と呼ぶ。固定部４２と可動部４３とは、中央部４１を通る中心線に対して略線対称である。可動部４３は、固定部４２の上端から斜め下方に延びる。 When paying attention to the elastic member 4 on the right side in FIG. It is fixed to the case 2 by being fixed to the case 2. Further, a portion 43 of the elastic member 4 extending from the center portion 41 to the right side of the support portion 22 is in contact with the terminal portion 3 extending in the vertical direction. When the portion 43 of the elastic member 4 is pushed downward by the operating portion 5, it is elastically deformed and bent downward using the upper end portion of the support portion 22 as a fulcrum. Further, when the downward pressing force on the portion 43 is removed, the portion 43 returns to its original state due to restoring force (that is, returns elastically). In the following description, the portion 42 and the portion 43 of the elastic member 4 will be referred to as a “fixed portion 42” and a “movable portion 43”, respectively. The fixed part 42 and the movable part 43 are approximately symmetrical with respect to a center line passing through the central part 41. The movable part 43 extends diagonally downward from the upper end of the fixed part 42.

図２に示す状態では、弾性部材４の可動部４３の先端が、上述のように、挿入穴２１よりも下側において端子部３に接触し、挿入穴２１の下端部を下側から閉鎖している。以下の説明では、図２に示す状態を「挿入穴閉鎖状態」と呼ぶ。また、挿入穴閉鎖状態は、挿入穴２１に電線が挿入される前の状態、すなわち、接続機器１が使用される前の初期状態である。 In the state shown in FIG. 2, the tip of the movable portion 43 of the elastic member 4 contacts the terminal portion 3 below the insertion hole 21, as described above, and closes the lower end of the insertion hole 21 from below. ing. In the following description, the state shown in FIG. 2 will be referred to as the "insertion hole closed state." Further, the insertion hole closed state is a state before the electric wire is inserted into the insertion hole 21, that is, an initial state before the connecting device 1 is used.

挿入穴閉鎖状態（すなわち、初期状態）の弾性部材４は、固定部４２と可動部４３とが近づく向きに少し撓んでいる。これにより、弾性部材４がケース２から脱落することを防止することができる。なお、図２中の左側には、撓みの無い状態の弾性部材４を二点鎖線にて示す。また、図２に示す例では、ケース２の支持部２２が、固定部４２と可動部４３とが近づく向きの弾性部材４の撓み（すなわち、弾性部材４の屈曲）を制限するストッパの役割を果たす。 The elastic member 4 in the insertion hole closed state (that is, the initial state) is slightly bent in the direction in which the fixed part 42 and the movable part 43 approach each other. Thereby, the elastic member 4 can be prevented from falling off from the case 2. Note that on the left side of FIG. 2, the elastic member 4 in an undeformed state is shown by a chain double-dashed line. Further, in the example shown in FIG. 2, the support part 22 of the case 2 plays the role of a stopper to limit the deflection of the elastic member 4 (that is, the bending of the elastic member 4) in the direction in which the fixed part 42 and the movable part 43 approach each other. Fulfill.

操作部５は、上下方向に延びる略柱状または略板状の部材である。操作部５は、ケース２に設けられた上下方向に延びる穴部（以下、「移動経路２４」と呼ぶ。）の内部に位置する。操作部５は、移動経路２４に沿って上下方向に移動可能である。移動経路２４は、ケース２の上面２５に開口し、当該上面２５から略下方に延びる。 The operating section 5 is a substantially columnar or substantially plate-like member that extends in the vertical direction. The operating section 5 is located inside a hole provided in the case 2 and extending in the vertical direction (hereinafter referred to as the "movement path 24"). The operation unit 5 is movable in the vertical direction along the movement path 24. The moving path 24 opens on the upper surface 25 of the case 2 and extends substantially downward from the upper surface 25.

操作部５は、上端部５１と、連結部５２と、下端部５３とを備える。上端部５１、連結部５２および下端部５３は、この順序で上側から下側に向かって繋がる一繋がりの部材である。操作部５は、例えば樹脂製である。操作部５の上端部５１は、例えば略直方体状の部位である。上端部５１の上面５１１は、上下方向に略垂直な平面である。上端部５１の上面５１１の中央部には、下向きに凹む操作凹部が設けられる。連結部５２は、上端部５１の下端から下方に延び、上端部５１と下端部５３とを連結する。連結部５２は、例えば、厚さ方向の幅が左右方向の幅よりも大きい略板状の部位である。下端部５３は、連結部５２の下端から下方に延びる。下端部５３は、例えば、略板状または略柱状の部位である。 The operating portion 5 includes an upper end portion 51, a connecting portion 52, and a lower end portion 53. The upper end portion 51, the connecting portion 52, and the lower end portion 53 are a continuous member connected in this order from the upper side to the lower side. The operation unit 5 is made of resin, for example. The upper end portion 51 of the operating portion 5 is, for example, a substantially rectangular parallelepiped-shaped portion. The upper surface 511 of the upper end portion 51 is a plane substantially perpendicular to the up-down direction. A downwardly recessed operation recess is provided in the center of the upper surface 511 of the upper end portion 51 . The connecting portion 52 extends downward from the lower end of the upper end portion 51 and connects the upper end portion 51 and the lower end portion 53. The connecting portion 52 is, for example, a substantially plate-shaped portion whose width in the thickness direction is larger than its width in the left-right direction. The lower end portion 53 extends downward from the lower end of the connecting portion 52. The lower end portion 53 is, for example, a substantially plate-shaped or substantially columnar portion.

上端部５１の左右方向の幅は、上端部５１の上下方向の略全長に亘って略一定である。連結部５２の左右方向の幅は、連結部５２の上下方向の略全長に亘って略一定である。下端部５３の左右方向の幅は、下端部５３の上部において略一定であり、当該上部から下方に向かうに従って漸次減少する。上端部５１の左右方向の幅は、連結部５２の左右方向の幅よりも大きい。下端部５３の上端の左右方向の幅は、連結部５２の下端の左右方向の幅よりも大きい。連結部５２の左右両側の側面は、左右方向に略垂直であり、上下方向に略平行に延びる。 The width of the upper end portion 51 in the left-right direction is substantially constant over substantially the entire length of the upper end portion 51 in the vertical direction. The width of the connecting portion 52 in the left-right direction is substantially constant over substantially the entire length of the connecting portion 52 in the vertical direction. The width of the lower end portion 53 in the left-right direction is approximately constant at the upper portion of the lower end portion 53, and gradually decreases downward from the upper portion. The width of the upper end portion 51 in the left-right direction is larger than the width of the connecting portion 52 in the left-right direction. The width of the upper end of the lower end portion 53 in the left-right direction is larger than the width of the lower end of the connecting portion 52 in the left-right direction. The left and right side surfaces of the connecting portion 52 are substantially perpendicular to the left-right direction and extend substantially parallel to the up-down direction.

図２中の右側の操作部５に注目すると、当該操作部５の上端部５１は、連結部５２の上端から左側に突出する。上端部５１の左側の上端部には、上面５１１から左斜め下方へと向かう第１傾斜面５６が設けられる。換言すれば、第１傾斜面５６は、下方に向かうに従って移動経路２４の中心線（すなわち、左右方向および厚さ方向における移動経路２４の略中心を通って上下方向に延びる直線）から離れる方向に傾斜する面である。図２に示す例では、操作部５の第１傾斜面５６と上面５１１との成す角度は、約４５°である。当該角度は、０°よりも大きく、かつ、９０°よりも小さい。 If we pay attention to the operating section 5 on the right side in FIG. 2, the upper end 51 of the operating section 5 protrudes to the left from the upper end of the connecting section 52. A first inclined surface 56 extending diagonally downward to the left from the upper surface 511 is provided at the left upper end portion of the upper end portion 51 . In other words, the first inclined surface 56 extends downwardly in a direction away from the center line of the movement path 24 (that is, a straight line extending vertically through approximately the center of the movement path 24 in the left-right direction and the thickness direction). It is an inclined surface. In the example shown in FIG. 2, the angle between the first inclined surface 56 and the upper surface 511 of the operating section 5 is approximately 45 degrees. The angle is larger than 0° and smaller than 90°.

操作部５の下端部５３の左側の側面は、上端から上下方向に略平行に下方へと延び、その後、下方に向かうに従って右側へと向かう。弾性部材４は、下端部５３の左側の側面と部分的に接触する。操作部５の下端部５３は、連結部５２の下端から右側に突出する。これにより、連結部５２の下端（すなわち、下端部５３の上端）に、右側へと突出する操作段差部５５が形成される。 The left side surface of the lower end portion 53 of the operating portion 5 extends downward from the upper end substantially parallel to the vertical direction, and then moves to the right as it goes downward. The elastic member 4 partially contacts the left side surface of the lower end portion 53. A lower end portion 53 of the operating portion 5 protrudes from the lower end of the connecting portion 52 to the right side. As a result, an operation step portion 55 that protrudes to the right is formed at the lower end of the connecting portion 52 (that is, the upper end of the lower end portion 53).

図２に示す挿入穴閉鎖状態では、操作部５の操作段差部５５がケース２の一部に係止することにより、操作部５の上方への移動が制限される。操作部５の下端部５３は、上述のように弾性部材４の可動部４３に接触しており、弾性部材４の復元力により、操作段差部５５がケース２の上記一部に押し付けられる。これにより、操作部５がケース２に係止されるため、操作部５が図２に示す位置よりも上側へと移動することが防止される。接続機器１を組み立てる際には、操作部５は、撓んでいない状態（すなわち、非圧縮状態）の弾性部材４の可動部４３が存在するはずの領域に先に配置されており、弾性部材４は、撓んだ状態でケース２に取り付けられる。これにより、上記構造が実現される。 In the insertion hole closed state shown in FIG. 2, the operation step portion 55 of the operation portion 5 is engaged with a part of the case 2, thereby restricting upward movement of the operation portion 5. The lower end portion 53 of the operating portion 5 is in contact with the movable portion 43 of the elastic member 4 as described above, and the operating step portion 55 is pressed against the above-mentioned portion of the case 2 due to the restoring force of the elastic member 4. As a result, the operating section 5 is locked to the case 2, so that the operating section 5 is prevented from moving above the position shown in FIG. When assembling the connected device 1, the operating section 5 is first placed in a region where the movable section 43 of the elastic member 4 in an unflexed state (that is, in an uncompressed state) is supposed to exist, and is attached to the case 2 in a bent state. This realizes the above structure.

図２に示す挿入穴閉鎖状態では、操作部５の上端部５１の上面５１１は、ケース２の上面２５のうち操作部５の周囲の領域と略同一平面上に位置する。あるいは、操作部５の上端部５１の上面５１１は、ケース２の上面２５のうち操作部５の周囲の領域よりもケース２の内部（すなわち、当該領域よりも下側）に位置する。また、図３に示すように、操作部５の厚さ方向の両側面５１３は、ケース２の厚さ方向の両側面２６のうち操作部５の周囲の領域よりもケース２の内部に位置し、または、当該領域と略同一平面上に位置する。操作部５の他の表面についても同様である。換言すれば、図２に示す挿入穴閉鎖状態では、操作部５の表面は、ケース２の表面のうち操作部５の周囲の領域（すなわち、移動経路２４の周囲の領域）よりもケース２の内部に位置し、または、当該領域と略同一平面上に位置する。 In the insertion hole closed state shown in FIG. 2, the upper surface 511 of the upper end portion 51 of the operating section 5 is located on substantially the same plane as the area around the operating section 5 on the upper surface 25 of the case 2. Alternatively, the upper surface 511 of the upper end portion 51 of the operating section 5 is located inside the case 2 (that is, below the region) than the area around the operating section 5 on the upper surface 25 of the case 2 . Further, as shown in FIG. 3, both side surfaces 513 of the operating portion 5 in the thickness direction are located inside the case 2 than the area around the operating portion 5 among the both side surfaces 26 of the case 2 in the thickness direction. , or located substantially on the same plane as the area. The same applies to other surfaces of the operating section 5. In other words, in the insertion hole closed state shown in FIG. It is located inside or is located approximately on the same plane as the area.

ケース２には、図２に示す操作部５の上面５１１よりも下方の移動経路２４内において、第１傾斜面５６と略平行に上下方向に対して傾斜する第２傾斜面２４１が設けられる。図２中の右側の移動経路２４では、第２傾斜面２４１は、操作部５の上端部５１の左側に位置し、下方に向かうに従って上端部５１から離れる方向（すなわち、左斜め下方）に延びる。移動経路２４の左右方向の幅は、第２傾斜面２４１の位置において、下方に向かうに従って漸次増大する。図２に示す挿入穴閉鎖状態では、第２傾斜面２４１は、第１傾斜面５６から下側に離間した位置に位置する。図２中の左側の移動経路２４では、第２傾斜面２４１は、右斜め下方に延びる。 The case 2 is provided with a second inclined surface 241 that is substantially parallel to the first inclined surface 56 and inclined in the vertical direction within the movement path 24 below the upper surface 511 of the operating section 5 shown in FIG. In the movement path 24 on the right side in FIG. 2, the second inclined surface 241 is located to the left of the upper end 51 of the operating section 5, and extends in a direction away from the upper end 51 as it goes downward (that is, diagonally downward to the left). . The width of the moving path 24 in the left-right direction gradually increases downward at the position of the second inclined surface 241. In the insertion hole closed state shown in FIG. 2, the second inclined surface 241 is located at a position spaced downward from the first inclined surface 56. In the left movement path 24 in FIG. 2, the second inclined surface 241 extends diagonally downward to the right.

次に、接続機器１に対する電線の接続の流れについて、図２、図５ないし図８を参照しつつ説明する。なお、以下では、図中の右側の挿入穴２１に電線を接続する際の様子について説明する。図中の左側の挿入穴２１に電線を接続する場合については、左右反対向きである点を除き、作業員の動作は略同様である。 Next, the flow of connecting electric wires to the connecting device 1 will be described with reference to FIGS. 2, 5 to 8. In addition, below, the situation when connecting an electric wire to the insertion hole 21 on the right side in the figure will be explained. When connecting an electric wire to the insertion hole 21 on the left side of the figure, the operator's actions are substantially the same except that the left and right directions are opposite.

まず、図２に示す挿入穴閉鎖状態から操作部５がケース２の内部に向かって押し込まれ、移動経路２４に沿って下方へと移動する。操作部５が押し込まれる際には、例えば、作業員が通常のマイナスドライバー等の先端を、操作部５の上端部５１の操作凹部に接触させ、当該マイナスドライバーを介して操作部５に下向きの力を加える。操作部５の下方への移動に従って、弾性部材４は撓んで弾性部材４の形状が変更される。具体的には、図５に示すように、弾性部材４の可動部４３が、操作部５の下端部５３により下方へと押し下げられ、端子部３から左側へと離間する。これにより、挿入穴２１の下端部が開放される。以下の説明では、図５に示す接続機器１の状態を「挿入穴開放状態」という。 First, the operating section 5 is pushed toward the inside of the case 2 from the insertion hole closed state shown in FIG. 2, and moves downward along the movement path 24. When the operating section 5 is pushed in, for example, a worker brings the tip of a normal flathead screwdriver or the like into contact with the operation recess in the upper end 51 of the operating section 5, and inserts a downward direction into the operating section 5 through the flathead screwdriver. Add force. As the operating portion 5 moves downward, the elastic member 4 is bent and the shape of the elastic member 4 is changed. Specifically, as shown in FIG. 5, the movable portion 43 of the elastic member 4 is pushed down by the lower end portion 53 of the operating portion 5 and separated from the terminal portion 3 to the left. As a result, the lower end of the insertion hole 21 is opened. In the following description, the state of the connected device 1 shown in FIG. 5 will be referred to as the "insertion hole open state."

図２に示す挿入穴閉鎖状態から図５に示す挿入穴開放状態への移行時には、操作部５が弾性部材４との接触を維持しつつ下方へと移動し、操作部５の第１傾斜面５６とケース２の第２傾斜面２４１とが上下方向の略同じ位置に位置する。このとき、弾性部材４の復元力により操作部５の下端部５３が右向きに押されて操作部５が僅かに傾く。具体的には、操作部５の下端部５３は、移動経路２４と交差する方向である右向きに移動し、操作部５の上端部５１は、移動経路２４と交差する方向である左向きに移動する。これにより、操作部５の第１傾斜面５６は、ケース２の第２傾斜面２４１に接触しつつ左向きに移動し、第２傾斜面２４１の下側に位置する。 When transitioning from the insertion hole closed state shown in FIG. 2 to the insertion hole open state shown in FIG. 56 and the second inclined surface 241 of the case 2 are located at substantially the same position in the vertical direction. At this time, the restoring force of the elastic member 4 pushes the lower end 53 of the operating section 5 rightward, causing the operating section 5 to tilt slightly. Specifically, the lower end 53 of the operating unit 5 moves to the right, which is the direction that intersects the movement path 24, and the upper end 51 of the operating unit 5 moves to the left, which is the direction that intersects the movement path 24. . As a result, the first inclined surface 56 of the operating section 5 moves leftward while contacting the second inclined surface 241 of the case 2, and is located below the second inclined surface 241.

第２傾斜面２４１は、上述の僅かに傾いた状態の操作部５における第１傾斜面５６と略平行になるように形成されている。ただし、操作部５の当該傾きは僅かであるため、操作部５が傾いていない状態であっても、第２傾斜面２４１は第１傾斜面５６と略平行である。 The second inclined surface 241 is formed to be substantially parallel to the first inclined surface 56 of the operating section 5 which is in the slightly inclined state described above. However, since the inclination of the operating section 5 is slight, the second inclined surface 241 is substantially parallel to the first inclined surface 56 even when the operating section 5 is not inclined.

図６は、この状態の第１傾斜面５６および第２傾斜面２４１近傍の部位を拡大して示す断面図である。第１傾斜面５６は、弾性部材４の復元力により第２傾斜面２４１に対して下側から当接して上向きに押圧される。これにより、ケース２の第２傾斜面２４１が、弾性部材４の復元力を部分的に支持する。したがって、操作部５を下向きに押し込んだ状態で維持するために必要な作業員の力が軽減される。なお、第２傾斜面２４１により支持される弾性部材４の復元力は、弾性部材４の全復元力よりも小さい。したがって、第２傾斜面２４１による支持のみにより、操作部５が第２傾斜面２４１に係止されることはない。 FIG. 6 is an enlarged sectional view showing a portion near the first inclined surface 56 and the second inclined surface 241 in this state. The first inclined surface 56 comes into contact with the second inclined surface 241 from below and is pressed upward by the restoring force of the elastic member 4 . Thereby, the second inclined surface 241 of the case 2 partially supports the restoring force of the elastic member 4. Therefore, the force required by the operator to maintain the operating portion 5 in a downwardly pushed state is reduced. Note that the restoring force of the elastic member 4 supported by the second inclined surface 241 is smaller than the total restoring force of the elastic member 4. Therefore, the operating portion 5 is not locked to the second inclined surface 241 only by being supported by the second inclined surface 241.

接続機器１では、操作部５の上述の傾斜（すなわち、上端部５１の左側への移動）は短時間のうちに行われ、マイナスドライバーを握る作業員の手に、当該傾斜に起因する手応え（いわゆる、クリック感）が発生する。また、操作部５の当該傾斜に起因する音（例えば、コツンっという衝突音）も発生する。したがって、作業員は、挿入穴閉鎖状態から挿入穴開放状態への移行完了を容易に認識することができる。 In the connected device 1, the above-mentioned tilting of the operation unit 5 (that is, the movement of the upper end portion 51 to the left) is performed in a short time, and the worker holding the flathead screwdriver feels a tactile sensation (due to the tilting) in his hand. A so-called click feeling occurs. Moreover, a sound (for example, a crashing sound) caused by the tilting of the operating section 5 is also generated. Therefore, the operator can easily recognize the completion of the transition from the insertion hole closed state to the insertion hole open state.

さらに、接続機器１では、操作部５の上述の傾斜と略同時に、操作部５の上端部５１の左側の下端が、ケース２の移動経路２４内に設けられた上下方向に略垂直な停止面２４２に上側から接触する。これにより、操作部５の下方への過剰な移動を制限することができる。また、操作部５の上端部５１と停止面２４２との接触による手応えおよび／または音の発生により、作業員は、挿入穴閉鎖状態から挿入穴開放状態への移行完了をさらに容易に認識することもできる。 Further, in the connected device 1, substantially at the same time as the above-mentioned inclination of the operating section 5, the lower end of the left side of the upper end portion 51 of the operating section 5 is connected to a stop surface provided in the movement path 24 of the case 2 that is substantially perpendicular to the vertical direction. 242 from above. Thereby, excessive downward movement of the operating section 5 can be restricted. Furthermore, the operator can more easily recognize the completion of the transition from the insertion hole closed state to the insertion hole open state by the tactile sensation and/or sound produced by the contact between the upper end 51 of the operating section 5 and the stop surface 242. You can also do it.

図５に示す挿入穴開放状態では、操作部５の上端部５１の上面５１１は、ケース２の上面２５のうち操作部５の周囲の領域よりもケース２の内部（すなわち、当該領域よりも下側）に位置する。あるいは、操作部５の上端部５１の上面５１１は、ケース２の上面２５のうち操作部５の周囲の領域と略同一平面上に位置していてもよい。操作部５の他の表面についても同様である。換言すれば、図５に示す挿入穴開放状態では、操作部５の表面は、ケース２の表面のうち操作部５の周囲の領域（すなわち、移動経路２４の周囲の領域）よりもケース２の内部に位置し、または、当該領域と略同一平面上に位置する。 In the insertion hole open state shown in FIG. located on the side). Alternatively, the upper surface 511 of the upper end portion 51 of the operating section 5 may be located on substantially the same plane as the area around the operating section 5 on the upper surface 25 of the case 2. The same applies to other surfaces of the operating section 5. In other words, in the insertion hole open state shown in FIG. It is located inside or is located approximately on the same plane as the area.

図５に示す挿入穴開放状態では、弾性部材４は、後述する結線状態の弾性部材４よりも撓んでおり、電線を端子部３との間で挟持しない。換言すれば、図５に示す接続機器１の状態である挿入穴開放状態は、弾性部材４と端子部３との間の電線の挟持が解除された「非結線状態」である。 In the insertion hole open state shown in FIG. 5, the elastic member 4 is more bent than the elastic member 4 in the connected state, which will be described later, and does not pinch the electric wire with the terminal portion 3. In other words, the insertion hole open state, which is the state of the connecting device 1 shown in FIG. 5, is a "non-wired state" in which the electric wire is no longer clamped between the elastic member 4 and the terminal portion 3.

続いて、弾性部材４が挿入穴開放状態にて維持された状態で、電線９１が、図５中に二点鎖線にて示すように接続機器１の挿入穴２１に挿入される。電線９１は、例えば単線であってもよく、より線であってもよい。また、電線９１は、先端部に棒状圧着端子等が設けられたより線であってもよい。電線９１の先端部の直径は、例えば、０．４２ｍｍ以上であることが好ましい。電線９１の先端部の直径は、現実的には、２．３ｍｍ以下である。電線９１の先端部の直径は、様々に変更されてよい。また、電線９１の先端部以外の部位の直径も、様々に変更されてよい。 Subsequently, with the elastic member 4 maintained in the insertion hole open state, the electric wire 91 is inserted into the insertion hole 21 of the connecting device 1 as shown by the two-dot chain line in FIG. The electric wire 91 may be, for example, a single wire or a stranded wire. Further, the electric wire 91 may be a stranded wire having a rod-shaped crimp terminal or the like provided at the tip. It is preferable that the diameter of the tip of the electric wire 91 is, for example, 0.42 mm or more. The diameter of the tip of the electric wire 91 is actually 2.3 mm or less. The diameter of the tip of the electric wire 91 may be changed in various ways. Further, the diameters of the parts other than the tip of the electric wire 91 may be changed in various ways.

電線９１は、挿入穴２１内にて下方へと移動され、図７に示すように、端子部３と挿入穴開放状態の弾性部材４との間に挿入される。その後、操作部５を押し込む作業員の力が弱められ、弾性部材４の復元力が、作業員の力と第２傾斜面２４１による支持力との合計よりも大きくなることにより、弾性部材４の可動部４３が右斜め上方へと移動し、図８に示すように、電線９１に左側から接触する。弾性部材４の可動部４３は、上記復元力により、電線９１を端子部３に押し付けて端子部３との間で挟持する。これにより、電線９１と端子部３とが電気的かつ機械的に接続される。換言すれば、電線９１が接続機器１に結線される。以下の説明では、図８に示す状態を「結線状態」という。結線状態の弾性部材４は、上述のように、電線９１を端子部３との間で挟持している。 The electric wire 91 is moved downward within the insertion hole 21 and, as shown in FIG. 7, is inserted between the terminal portion 3 and the elastic member 4 with the insertion hole open. Thereafter, the force of the worker pushing in the operating part 5 is weakened, and the restoring force of the elastic member 4 becomes larger than the sum of the force of the worker and the supporting force by the second inclined surface 241. The movable part 43 moves diagonally upward to the right and contacts the electric wire 91 from the left side, as shown in FIG. The movable part 43 of the elastic member 4 presses the electric wire 91 against the terminal part 3 and clamps it between the electric wire 91 and the terminal part 3 by the above-mentioned restoring force. Thereby, the electric wire 91 and the terminal portion 3 are electrically and mechanically connected. In other words, the electric wire 91 is connected to the connected device 1. In the following description, the state shown in FIG. 8 will be referred to as a "wired state." The elastic member 4 in the connected state holds the electric wire 91 between it and the terminal portion 3, as described above.

接続機器１では、また、弾性部材４の可動部４３の上記右斜め上方への移動により、操作部５の上方への移動が開始される。このとき、第１傾斜面５６は、第２傾斜面２４１に接触した状態を維持しつつ、第２傾斜面２４１に沿って右斜め上方へと移動する。操作部５は、図７に示す挿入穴開放状態から上方に移動し、下端部５３が弾性部材４の可動部４３に接触した状態で停止する。結線状態における操作部５の第１傾斜面５６は、第２傾斜面２４１よりも上側に位置する。 In the connected device 1, when the movable portion 43 of the elastic member 4 moves diagonally upward to the right, upward movement of the operating portion 5 is started. At this time, the first inclined surface 56 moves obliquely upward and to the right along the second inclined surface 241 while maintaining the state in which it is in contact with the second inclined surface 241 . The operating portion 5 moves upward from the insertion hole open state shown in FIG. 7 and stops with the lower end portion 53 contacting the movable portion 43 of the elastic member 4. The first inclined surface 56 of the operating section 5 in the connected state is located above the second inclined surface 241.

図８に示す結線状態では、操作部５の上端部５１の上面５１１は、ケース２の上面２５のうち操作部５の周囲の領域よりもケース２の内部（すなわち、当該領域よりも下側）に位置する。あるいは、操作部５の上端部５１の上面５１１は、ケース２の上面２５のうち操作部５の周囲の領域と略同一平面上に位置していてもよい。操作部５の他の表面についても同様である。換言すれば、図８に示す結線状態では、操作部５の表面は、ケース２の表面のうち操作部５の周囲の領域（すなわち、移動経路２４の周囲の領域）よりもケース２の内部に位置し、または、当該領域と略同一平面上に位置する。 In the wiring state shown in FIG. 8, the upper surface 511 of the upper end portion 51 of the operating section 5 is located inside the case 2 (i.e., below the region) than the area around the operating section 5 on the upper surface 25 of the case 2. Located in Alternatively, the upper surface 511 of the upper end portion 51 of the operating section 5 may be located on substantially the same plane as the area around the operating section 5 on the upper surface 25 of the case 2. The same applies to other surfaces of the operating section 5. In other words, in the wire connection state shown in FIG. or located approximately on the same plane as the area.

なお、図８に示す結線状態において、図８中の上側が重力方向下側となるように接続機器１が配置されている場合、操作部５は、重力により弾性部材４から図中の上方に離間する。そして、操作部５の操作段差部５５が、図２に示す挿入穴閉鎖状態と同様に、ケース２の一部に係止され、操作部５の上方への移動が制限される。したがって、操作部５が図２に示す位置よりも上側へと移動することが防止される。 In addition, in the connection state shown in FIG. 8, if the connected device 1 is arranged so that the upper side in FIG. Separate. Then, the operation step portion 55 of the operation section 5 is locked to a part of the case 2, similarly to the insertion hole closed state shown in FIG. 2, and upward movement of the operation section 5 is restricted. Therefore, the operation unit 5 is prevented from moving upward from the position shown in FIG.

電線９１を接続機器１から取り外す際には、例えば、作業員が通常のマイナスドライバー等の先端を、操作部５の上端部５１の操作凹部に接触させ、当該マイナスドライバーを介して操作部５に下向きの力を加える。そして、操作部５を下方に移動し、図７に示すように挿入穴開放状態とする。挿入穴開放状態では、上述のように、弾性部材４は撓んで可動部４３が電線９１から左側へと離間する。換言すれば、弾性部材４および端子部３による電線９１の挟持が解除される。また、操作部５が傾斜することにより、操作部５の第１傾斜面５６がケース２の第２傾斜面２４１に下側から当接し、弾性部材４の復元力の一部が第２傾斜面２４１により支持される。 When removing the electric wire 91 from the connected device 1, for example, a worker brings the tip of a regular flathead screwdriver or the like into contact with the operation recess in the upper end 51 of the operating section 5, and then inserts the tip of the operating section 5 into the operating section 5 through the flathead screwdriver. Apply downward force. Then, the operating portion 5 is moved downward to open the insertion hole as shown in FIG. In the insertion hole open state, as described above, the elastic member 4 is bent and the movable portion 43 is separated from the electric wire 91 to the left. In other words, the clamping of the electric wire 91 by the elastic member 4 and the terminal portion 3 is released. Further, as the operating section 5 is tilted, the first inclined surface 56 of the operating section 5 comes into contact with the second inclined surface 241 of the case 2 from below, and a part of the restoring force of the elastic member 4 is transferred to the second inclined surface 241. 241.

このときも、上記と同様に、操作部５の傾斜に起因する手応えおよび音が発生するため、作業員は、接続機器１が挿入穴開放状態（すなわち、非結線状態）となったことを容易に認識することができる。また、操作部５の上端部５１と停止面２４２との接触による手応えおよび／または音の発生により、接続機器１が挿入穴開放状態（すなわち、非結線状態）となったことをさらに容易に認識することができる。 At this time, as well as the above, since a tactile response and sound are generated due to the tilt of the operating section 5, the operator can easily recognize that the insertion hole of the connecting device 1 is in the open state (that is, the unconnected state). can be recognized. Furthermore, it is easier to recognize that the connection device 1 has entered the insertion hole open state (i.e., non-wired state) by the generation of a tactile sensation and/or sound caused by the contact between the upper end 51 of the operating section 5 and the stop surface 242. can do.

接続機器１では、弾性部材４は、図２に示す挿入穴閉鎖状態と、図５および図７に示す挿入穴開放状態と、図８に示す結線状態との間で変形可能である。以下の説明では、図８に示すように、結線状態の弾性部材４に接触する操作部５の位置を「第１位置」と呼ぶ。また、図５および図７に示すように、挿入穴開放状態（すなわち、非結線状態）の弾性部材４に接触する操作部５の位置を「第２位置」と呼ぶ。さらに、図２に示すように、操作段差部５５がケース２の一部に係止する操作部５の位置を「第３位置」と呼ぶ。 In the connecting device 1, the elastic member 4 is deformable between the insertion hole closed state shown in FIG. 2, the insertion hole open state shown in FIGS. 5 and 7, and the wire connection state shown in FIG. In the following description, as shown in FIG. 8, the position of the operating portion 5 in contact with the elastic member 4 in the connected state will be referred to as a "first position." Further, as shown in FIGS. 5 and 7, the position of the operating portion 5 in contact with the elastic member 4 in the insertion hole open state (that is, in the unconnected state) is referred to as a "second position." Furthermore, as shown in FIG. 2, the position of the operating portion 5 where the operating step portion 55 is engaged with a part of the case 2 is referred to as a “third position”.

上述の移動経路２４は、操作部５の第３位置、第１位置および第２位置をこの順に結ぶ。第３位置は、移動経路２４において、第１位置を挟んで第２位置とは反対側に位置する。第２位置では、上述のように、操作部５の第１傾斜面５６はケース２の第２傾斜面２４１に下側から当接する。第３位置では、操作段差部５５がケース２の一部に係止することにより、操作部５の上方への移動（すなわち、第２位置から離れる方向への移動）が制限される。なお、第３位置では、操作部５の一部がケース２の一部に係止していればよく、必ずしも操作段差部５５がケース２の一部に係止する必要はない。 The above-mentioned movement route 24 connects the third position, first position, and second position of the operating section 5 in this order. The third position is located on the opposite side of the movement path 24 from the second position with the first position in between. In the second position, as described above, the first inclined surface 56 of the operating section 5 contacts the second inclined surface 241 of the case 2 from below. In the third position, the operation step portion 55 is engaged with a portion of the case 2, thereby restricting the upward movement of the operation portion 5 (that is, the movement away from the second position). Note that in the third position, it is only necessary that a part of the operation part 5 is locked to a part of the case 2, and the operation step part 55 does not necessarily need to be locked to a part of the case 2.

以上に説明したように、電線９１が接続される接続機器１は、ケース２と、端子部３と、弾性部材４と、操作部５とを備える。端子部３は、導電性であり、ケース２に固定される。弾性部材４は、ケース２に取り付けられる。弾性部材４は、復元力により電線９１を端子部３に押し付けて挟持する。操作部５は、ケース２に設けられた上下方向に延びる移動経路２４に沿って移動することにより、弾性部材４の形状を変更する。弾性部材４は、電線９１を端子部３との間で挟持している結線状態と、結線状態よりも撓んで端子部３との間の電線９１の挟持が解除された非結線状態（すなわち、挿入穴開放状態）との間で変形可能である。 As described above, the connecting device 1 to which the electric wire 91 is connected includes the case 2, the terminal section 3, the elastic member 4, and the operating section 5. The terminal portion 3 is conductive and fixed to the case 2. The elastic member 4 is attached to the case 2. The elastic member 4 presses and holds the electric wire 91 against the terminal portion 3 by its restoring force. The operating section 5 changes the shape of the elastic member 4 by moving along a moving path 24 provided in the case 2 and extending in the vertical direction. The elastic member 4 is in a connected state in which the electric wire 91 is held between the terminal part 3 and in a non-connected state in which the electric wire 91 is no longer held between the terminal part 3 by being bent than in the connected state (i.e., It can be deformed between the insertion hole open state) and the insertion hole open state.

操作部５は、第１位置において結線状態の弾性部材４に接触する。操作部５は、弾性部材４との接触状態を維持しつつ、第１位置よりも下側の第２位置へと押し込まれることにより、弾性部材４を非結線状態へと変形させる。操作部５は、下方に向かうに従って移動経路２４の中心線から離れる方向に傾斜する第１傾斜面５６を有する。ケース２は、移動経路２４内において第１傾斜面５６と平行に上下方向に対して傾斜する第２傾斜面２４１を有する。操作部５が第１位置に位置する状態では、第１傾斜面５６は第２傾斜面２４１から上側に離間した位置に位置する。操作部５が第２位置に位置する状態では、第１傾斜面５６は第２傾斜面２４１に下側から当接する。 The operating portion 5 contacts the connected elastic member 4 at the first position. The operating portion 5 deforms the elastic member 4 into a non-wired state by being pushed into the second position below the first position while maintaining the contact state with the elastic member 4. The operating portion 5 has a first inclined surface 56 that is inclined in a direction away from the center line of the movement path 24 as it goes downward. The case 2 has a second inclined surface 241 that is parallel to the first inclined surface 56 and inclined in the vertical direction within the movement path 24 . When the operating portion 5 is located at the first position, the first inclined surface 56 is located at a position spaced upward from the second inclined surface 241. When the operating portion 5 is in the second position, the first inclined surface 56 contacts the second inclined surface 241 from below.

このように、弾性部材４の復元力により上向きに押される操作部５が、第１傾斜面５６を介してケース２の第２傾斜面２４１に当接することにより、操作部５をケース２内に押し込んだ状態（すなわち、非結線状態）で維持する力を低減することができる。これにより、接続機器１の操作性を向上することができる。 In this way, the operating portion 5 pushed upward by the restoring force of the elastic member 4 comes into contact with the second inclined surface 241 of the case 2 via the first inclined surface 56, so that the operating portion 5 is pushed into the case 2. The force required to maintain the pressed state (that is, the unconnected state) can be reduced. Thereby, the operability of the connected device 1 can be improved.

上述のように、好ましくは、非結線状態の弾性部材４の復元力により、第１傾斜面５６は第２傾斜面２４１に対して上向きに押圧され、第２傾斜面２４１は弾性部材４の復元力を部分的に支持する。このため、非結線状態の接続機器１に電線９１を結線する際に、マイナスドライバー等により操作部５を下向きに押す力を緩めることにより、操作部５を第２位置から第１位置へと容易に移動させ、弾性部材４の可動部４３と端子部３との間に電線９１を容易に挟持させることができる。また、接続機器１から電線９１を抜き取った後、弾性部材４を非結線状態（すなわち、挿入穴開放状態）から挿入穴閉鎖状態へと戻す際にも同様に、マイナスドライバー等により操作部５を下向きに押す力を緩めることにより、操作部５を第２位置から第３位置へと容易に移動させることができる。したがって、電線９１の結線の際、あるいは、電線９１の結線解除の際に、マイナスドライバー等を移動経路２４に繰り返し挿入する必要がないため、接続機器１の操作性を向上することができる。 As described above, preferably, the first inclined surface 56 is pressed upward against the second inclined surface 241 by the restoring force of the unconnected elastic member 4, and the second inclined surface 241 is pressed against the restoring force of the elastic member 4 in the unconnected state. partially supports the force. Therefore, when connecting the electric wire 91 to the unconnected connected device 1, by relaxing the force of pushing the operating section 5 downward with a flat head screwdriver, etc., the operating section 5 can be easily moved from the second position to the first position. , the electric wire 91 can be easily held between the movable portion 43 of the elastic member 4 and the terminal portion 3. Similarly, when returning the elastic member 4 from the unconnected state (that is, the insertion hole open state) to the insertion hole closed state after removing the electric wire 91 from the connected device 1, the operation section 5 is pressed with a flathead screwdriver or the like. By relaxing the downward pushing force, the operating section 5 can be easily moved from the second position to the third position. Therefore, it is not necessary to repeatedly insert a flathead screwdriver or the like into the moving path 24 when connecting or disconnecting the electric wire 91, so that the operability of the connected device 1 can be improved.

上述のように、第１傾斜面５６は、操作部５の上端に設けられることが好ましい。これにより、第１傾斜面５６を視認可能とすることができるため、操作部５が第３位置から第２位置に到達するタイミング（すなわち、操作部５を押し込む力が低減されるタイミング）等を、比較的容易に直感的に把握することができる。したがって、接続機器１の操作性をさらに向上することができる。また、第１傾斜面５６を周囲の部位とは異なる色に着色している場合、操作部５が第２位置に位置することにより第１傾斜面５６の色が見えなくなるため、操作部５が第２位置に到達したことを視覚を通じてさらに容易に把握することができる。 As described above, the first inclined surface 56 is preferably provided at the upper end of the operating section 5. As a result, the first inclined surface 56 can be made visible, so the timing at which the operating section 5 reaches the second position from the third position (that is, the timing at which the force for pushing the operating section 5 is reduced), etc. , can be grasped relatively easily and intuitively. Therefore, the operability of the connected device 1 can be further improved. Further, if the first inclined surface 56 is colored in a different color from the surrounding parts, the color of the first inclined surface 56 becomes invisible when the operating section 5 is located at the second position, so that the operating section 5 It is possible to more easily visually recognize that the second position has been reached.

上述のように、弾性部材４は板バネであることが好ましい。これにより、接続機器１の構造を簡素化することができる。その結果、接続機器１の製造を容易とすることができる。 As mentioned above, the elastic member 4 is preferably a leaf spring. Thereby, the structure of the connected device 1 can be simplified. As a result, the connecting device 1 can be manufactured easily.

接続機器１では、図９に示すように、操作部５の第１傾斜面５６に凸部５６１が設けられ、ケース２の第２傾斜面２４１に凹部２４３が設けられてもよい。凹部２４３は、操作部５が上述の第２位置に位置する状態で、凸部５６１と嵌合する。これにより、操作部５をケース２内に押し込んだ状態で維持する力をさらに低減することができる。 In the connected device 1, as shown in FIG. 9, a convex portion 561 may be provided on the first inclined surface 56 of the operating portion 5, and a recessed portion 243 may be provided on the second inclined surface 241 of the case 2. The concave portion 243 fits into the convex portion 561 when the operating portion 5 is located at the second position described above. Thereby, it is possible to further reduce the force required to maintain the operation part 5 in the state of being pushed into the case 2.

また、接続機器１では、ケース２の第２傾斜面２４１に凸部が設けられ、操作部５の第１傾斜面５６に凹部が設けられてもよい。換言すれば、接続機器１では、第１傾斜面５６および第２傾斜面２４１のうち一方の面が凸部を有し、第１傾斜面５６および第２傾斜面２４１のうち他方の面が、操作部５が第２位置に位置する状態で当該凸部と嵌合する凹部を有することが好ましい。これにより、上述のように、操作部５をケース２内に押し込んだ状態（すなわち、非結線状態）で維持する力をさらに低減することができる。その結果、接続機器１の操作性をさらに向上することができる。なお、この場合であっても、操作部５を押し込む力を緩めると、弾性部材４の復元力により、操作部５は上方へと移動し、可動部４３は右上方へと移動する。 Furthermore, in the connected device 1, the second inclined surface 241 of the case 2 may be provided with a convex portion, and the first inclined surface 56 of the operating portion 5 may be provided with a recessed portion. In other words, in the connected device 1, one of the first inclined surface 56 and the second inclined surface 241 has a convex portion, and the other surface of the first inclined surface 56 and the second inclined surface 241 has a convex portion. It is preferable to have a recess that fits into the projection when the operating portion 5 is in the second position. Thereby, as described above, it is possible to further reduce the force required to maintain the operation unit 5 in the state where it is pushed into the case 2 (that is, in the unconnected state). As a result, the operability of the connected device 1 can be further improved. Even in this case, when the force for pushing the operating section 5 is relaxed, the operating section 5 moves upward due to the restoring force of the elastic member 4, and the movable section 43 moves to the upper right.

接続機器１では、図１０に太線にて示すように、第１傾斜面５６および第２傾斜面２４１が、周囲の部位よりも表面粗度が大きい粗面部５６２，２４４を有していてもよい。粗面部５６２と粗面部２４４とが接触することにより、第１傾斜面５６と第２傾斜面２４１との間の摩擦抵抗が増大するため、操作部５をケース２内に押し込んだ状態で維持する力をさらに低減することができる。 In the connected device 1, the first inclined surface 56 and the second inclined surface 241 may have rough surface portions 562, 244 having a larger surface roughness than the surrounding parts, as shown by the bold line in FIG. . Since the frictional resistance between the first inclined surface 56 and the second inclined surface 241 increases due to the contact between the rough surface section 562 and the rough surface section 244, the operation section 5 is maintained in a state pushed into the case 2. The force can be further reduced.

接続機器１では、第１傾斜面５６および第２傾斜面２４１のうち、少なくとも一方の面に粗面部が設けられていればよい。この場合であっても、第１傾斜面５６と第２傾斜面２４１との間の摩擦抵抗が増大するため、操作部５をケース２内に押し込んだ状態（すなわち、非結線状態）で維持する力をさらに低減することができる。その結果、接続機器１の操作性をさらに向上することができる。なお、当該摩擦抵抗が増大した状態であっても、操作部５を押し込む力を緩めると、弾性部材４の復元力により、操作部５は上方へと移動し、可動部４３は右上方へと移動する。 In the connected device 1, at least one of the first inclined surface 56 and the second inclined surface 241 may be provided with a rough surface portion. Even in this case, since the frictional resistance between the first inclined surface 56 and the second inclined surface 241 increases, the operation part 5 is maintained in the state pushed into the case 2 (that is, in the unconnected state). The force can be further reduced. As a result, the operability of the connected device 1 can be further improved. Note that even when the frictional resistance is increased, when the force pushing the operating section 5 is relaxed, the operating section 5 moves upward due to the restoring force of the elastic member 4, and the movable section 43 moves upward and to the right. Moving.

次に、本発明の第２の実施の形態に係る接続機器１ａについて説明する。図１１および図１２は、接続機器１ａの操作部５ａ近傍を拡大して示す断面図である。接続機器１ａは、図６に示す第１傾斜面５６および第２傾斜面２４１とは異なる位置に第１傾斜面５６ａおよび第２傾斜面２４１ａが設けられる点を除き、接続機器１と略同様の構造を有する。以下の説明では、接続機器１の構成に対応する接続機器１ａの構成に同符号を付す。 Next, a connection device 1a according to a second embodiment of the present invention will be described. FIGS. 11 and 12 are enlarged cross-sectional views showing the vicinity of the operating section 5a of the connected device 1a. The connected device 1a is substantially the same as the connected device 1 except that the first sloped surface 56a and the second sloped surface 241a are provided at different positions from the first sloped surface 56 and the second sloped surface 241 shown in FIG. Has a structure. In the following description, the configuration of the connected device 1a corresponding to the configuration of the connected device 1 is given the same reference numeral.

図１１は、接続機器１ａの右側の操作部５ａが第１位置に位置する状態（すなわち、結線状態）を示し、図１２は、当該操作部５ａが第２位置に位置する状態（すなわち、非結線状態）を示す。操作部５ａは、操作段差部５５の右側の端部（すなわち、連結部５２から遠い側の端部）に、第１傾斜面５６ａを有する。第１傾斜面５６ａは、操作部５ａの上端部５１よりも下側に設けられる。第１傾斜面５６ａは、操作段差部５５から右斜め下方へと向かう。換言すれば、第１傾斜面５６ａは、下方に向かうに従って移動経路２４の中心線から離れる方向に傾斜する面である。ケース２は、移動経路２４内において第１傾斜面５６ａと平行に上下方向に対して傾斜する第２傾斜面２４１ａを有する。 FIG. 11 shows a state in which the right operating section 5a of the connected device 1a is located at the first position (i.e., wire connection state), and FIG. connection status). The operating portion 5a has a first inclined surface 56a at the right end of the operating step portion 55 (that is, the end farthest from the connecting portion 52). The first inclined surface 56a is provided below the upper end portion 51 of the operating portion 5a. The first inclined surface 56a extends diagonally downward to the right from the operation step portion 55. In other words, the first inclined surface 56a is a surface that slopes away from the center line of the moving path 24 as it goes downward. The case 2 has a second inclined surface 241a that is parallel to the first inclined surface 56a and inclined in the vertical direction within the moving path 24.

図１１に示すように、操作部５ａが第１位置に位置する状態では、第１傾斜面５６ａは第２傾斜面２４１ａから上側に離間した位置に位置する。また、図１２に示すように、操作部５ａが第２位置に位置する状態では、第１傾斜面５６ａは第２傾斜面２４１ａに下側から当接する。これにより、図６に示す接続機器１と同様に、操作部５ａをケース２内に押し込んだ状態（すなわち、図１２に示す非結線状態）で維持する力を低減することができる。これにより、接続機器１ａの操作性を向上することができる。 As shown in FIG. 11, when the operating portion 5a is located at the first position, the first inclined surface 56a is located at a position spaced upward from the second inclined surface 241a. Further, as shown in FIG. 12, when the operating portion 5a is located at the second position, the first inclined surface 56a abuts the second inclined surface 241a from below. Thereby, similarly to the connected device 1 shown in FIG. 6, it is possible to reduce the force required to maintain the operating portion 5a in the state of being pushed into the case 2 (that is, the unconnected state shown in FIG. 12). Thereby, the operability of the connected device 1a can be improved.

接続機器１ａでは、接続機器１と同様に、非結線状態の弾性部材４の復元力により、第１傾斜面５６ａは第２傾斜面２４１ａに対して上向きに押圧され、第２傾斜面２４１ａは弾性部材４の復元力を部分的に支持することが好ましい。これにより、接続機器１と同様に、接続機器１ａの操作性を向上することができる。 In the connected device 1a, similarly to the connected device 1, the first inclined surface 56a is pressed upward against the second inclined surface 241a due to the restoring force of the elastic member 4 in the unconnected state, and the second inclined surface 241a is elastic. Preferably, the restoring force of the member 4 is partially supported. Thereby, similarly to the connected device 1, the operability of the connected device 1a can be improved.

上述のように、第１傾斜面５６ａは、操作部５ａの上端部５１よりも下側に設けられることが好ましい。これにより、第１傾斜面５６ａがケース２の内部に位置するため、操作部５ａの押し込みに使用されるマイナスドライバー等と衝突して破損することを防止することができる。 As described above, the first inclined surface 56a is preferably provided below the upper end 51 of the operating portion 5a. Thereby, since the first inclined surface 56a is located inside the case 2, it is possible to prevent the first inclined surface 56a from colliding with a flathead screwdriver or the like used for pushing the operating section 5a and being damaged.

接続機器１ａでは、接続機器１と同様に、弾性部材４は板バネであることが好ましい。これにより、接続機器１ａの構造を簡素化することができる。その結果、接続機器１ａの製造を容易とすることができる。 In the connected device 1a, similarly to the connected device 1, the elastic member 4 is preferably a plate spring. Thereby, the structure of the connected device 1a can be simplified. As a result, the connecting device 1a can be manufactured easily.

接続機器１ａでは、接続機器１と同様に、第１傾斜面５６ａおよび第２傾斜面２４１ａのうち一方の面が凸部を有し、第１傾斜面５６ａおよび第２傾斜面２４１ａのうち他方の面が、操作部５ａが第２位置に位置する状態で当該凸部と嵌合する凹部を有することが好ましい。これにより、接続機器１と同様に、操作部５ａをケース２内に押し込んだ状態（すなわち、非結線状態）で維持する力をさらに低減することができる。その結果、接続機器１ａの操作性をさらに向上することができる。 In the connected device 1a, similarly to the connected device 1, one of the first inclined surface 56a and the second inclined surface 241a has a convex portion, and the other of the first inclined surface 56a and the second inclined surface 241a has a convex portion. It is preferable that the surface has a recess that fits into the projection when the operating portion 5a is in the second position. Thereby, similarly to the connected device 1, it is possible to further reduce the force required to maintain the operating section 5a in the state of being pushed into the case 2 (that is, in the unconnected state). As a result, the operability of the connected device 1a can be further improved.

接続機器１ａでは、接続機器１と同様に、第１傾斜面５６ａおよび第２傾斜面２４１ａのうち、少なくとも一方の面に粗面部が設けられてもよい。これにより、接続機器１と同様に、操作部５ａをケース２内に押し込んだ状態（すなわち、非結線状態）で維持する力をさらに低減することができる。その結果、接続機器１ａの操作性をさらに向上することができる。 In the connected device 1a, similarly to the connected device 1, a rough surface portion may be provided on at least one of the first inclined surface 56a and the second inclined surface 241a. Thereby, similarly to the connected device 1, it is possible to further reduce the force required to maintain the operating section 5a in the state of being pushed into the case 2 (that is, in the unconnected state). As a result, the operability of the connected device 1a can be further improved.

例えば、接続機器１，１ａでは、端子部３、弾性部材４および操作部５，５ａの形状は様々に変更されてよい。例えば、弾性部材４は板バネ以外の部材（例えば、弦巻バネ）であってもよい。 For example, in the connected devices 1 and 1a, the shapes of the terminal portion 3, elastic member 4, and operation portions 5 and 5a may be changed in various ways. For example, the elastic member 4 may be a member other than a leaf spring (for example, a helical spring).

接続機器１では、第１位置、第２位置および第３位置に位置する操作部５の表面が、ケース２の表面のうち操作部５の周囲の領域よりも外側に突出していてもよい。接続機器１ａにおいても同様である。 In the connected device 1 , the surface of the operating section 5 located at the first position, the second position, and the third position may protrude outward from the area around the operating section 5 on the surface of the case 2 . The same applies to the connected device 1a.

接続機器１では、第２位置に位置する操作部５は、必ずしも、第１位置に位置する操作部５から左右方向に傾斜する必要はなく、第１位置に位置する操作部５と略同様の姿勢であってもよい。接続機器１ａにおいても同様である。 In the connected device 1, the operating section 5 located at the second position does not necessarily have to be tilted in the left-right direction from the operating section 5 located at the first position, and is substantially the same as the operating section 5 located at the first position. It may be a posture. The same applies to the connected device 1a.

接続機器１では、第１傾斜面５６および第２傾斜面２４１に、上述の互いに嵌合する凸部および凹部と、上記粗面部との双方が設けられてもよい。接続機器１ａにおいても同様である。 In the connecting device 1, the first inclined surface 56 and the second inclined surface 241 may be provided with both the above-mentioned mutually fitting convex portion and recessed portion and the above-mentioned rough surface portion. The same applies to the connected device 1a.

接続機器１では、操作部５における第１傾斜面５６の位置、および、ケース２における第２傾斜面２４１の位置は、様々に変更されてよい。接続機器１ａにおいても同様である。 In the connected device 1, the position of the first inclined surface 56 in the operation section 5 and the position of the second inclined surface 241 in the case 2 may be changed in various ways. The same applies to the connected device 1a.
