Description

端子装置及びそれを備えた配線器具TERMINAL DEVICE AND WIRING EQUIPMENT HAVING THE SAME
　本発明は、一般に端子装置及びそれを備えた配線器具に関し、より詳細には電線が挿入されることにより電線との接続が行われる端子装置及びそれを備えた配線器具に関する。 The present invention generally relates to a terminal device and a wiring device including the same, and more particularly to a terminal device that is connected to an electric wire by inserting the electric wire and a wiring device including the terminal device.
　従来、スイッチ等の配線器具への電線の結線を容易にする目的で、ねじによらずに結線可能な、いわゆる速結構造の端子装置が知られている（例えば特許文献１参照）。 2. Description of the Related Art Conventionally, a terminal device having a so-called quick connection structure that can be connected without using a screw is known for the purpose of facilitating the connection of electric wires to a wiring device such as a switch (see, for example, Patent Document 1).
　特許文献１に記載の端子装置は、導電材料からなる端子部（端子板）と、錠ばねとを備えている。端子部はＣ字状に形成され、錠ばねは端子部で囲まれた空間に収納されている。錠ばねは、弾性を有する板材を曲成することにより、中央片、鎖錠片及び押圧片が形成されている。鎖錠片及び押圧片は、中央片の両端部に形成されている。この端子装置では、電線が挿入口（電線挿入孔）から挿入されると、錠ばねのばね力により鎖錠片及び押圧片と、端子部の接触片との間に電線が挟持される。この状態で、鎖錠片の先端縁が電線に食い込むことによって電線が抜け止めされ、押圧片が電線を端子部の方へ押圧することにより端子部との間に電線を弾性挟持する。 The terminal device described in Patent Document 1 includes a terminal portion (terminal plate) made of a conductive material and a lock spring. The terminal portion is formed in a C shape, and the lock spring is housed in a space surrounded by the terminal portion. The lock spring is formed of a central piece, a lock piece and a pressing piece by bending an elastic plate. The locking piece and the pressing piece are formed at both ends of the central piece. In this terminal device, when the electric wire is inserted from the insertion port (electric wire insertion hole), the electric wire is sandwiched between the locking piece and the pressing piece and the contact piece of the terminal portion by the spring force of the lock spring. In this state, the leading edge of the locking piece bites into the electric wire to prevent the electric wire from coming off, and the pressing piece presses the electric wire toward the terminal portion, thereby elastically holding the electric wire between the terminal portion.
　上述したような従来の端子装置では、端子部と、端子部に電線を押し付ける部材（錠ばねの押圧片）とは別部品であるから、例えば端子部と錠ばねとの組立精度、又は温度特性等によって、端子部に対する電線の押付力にばらつきが生じる可能性がある。その結果、端子部に対する電線の接触状態が不安定になることがある。 In the conventional terminal device as described above, since the terminal portion and the member that presses the electric wire against the terminal portion (the pressing piece of the lock spring) are separate parts, for example, the assembly accuracy of the terminal portion and the lock spring, or temperature characteristics For example, the pressing force of the electric wire against the terminal portion may vary. As a result, the contact state of the electric wire with respect to the terminal portion may become unstable.

(1) Outline The terminal device 1 according to the first embodiment is a so-called quick connection terminal in which connection with the electric wire 100 is performed by inserting the electric wire 100 as shown in FIGS. 1A and 1B. The terminal device 1 includes a terminal portion 2 having conductivity. In the terminal device 1, when the electric wire 100 comes into contact with the terminal portion 2, electrical connection between the terminal portion 2 and the electric wire 100 is performed. In FIG. 1B, the electric wire 100 is indicated by an imaginary line (two-dot chain line). The terminal device 1 is used for wiring apparatuses, such as a switch or an outlet (outlet), for example. The wiring device 10 (see FIG. 9) provided with the terminal device 1 will be described in the section “(2.8) Wiring device”.

The electric wire 100 inserted from the insertion port 11 is inserted between the terminal portion 2 and the pressing portion 3, whereby the electric wire 100 is electrically connected to the terminal portion 2. Further, the electric wire 100 is inserted between the terminal portion 2 and the lock portion 4, so that the movement toward the insertion port 11 is restricted by the lock portion 4, and the electric wire 100 is prevented from coming off. Here, the insertion port 11 may be a space through which the electric wire 100 introduced between the terminal portion 2 and the pressing portion 3 and the locking portion 4 passes, and the terminal device 1 includes the insertion port 11 with the substance.

The electric wire 100 may be either a single wire whose core wire is a single conductor or a stranded wire whose core wire is a plurality of conducting wires.
　（２）詳細
　（２．１）基本構成
　以下、端子装置１の基本構成について、図１Ａ～図３Ｂを参照して詳しく説明する。 (2) Details (2.1) Basic Configuration The basic configuration of the terminal device 1 will be described in detail below with reference to FIGS. 1A to 3B.
　以下では、端子部２と押付部３とが対向する方向である「対向方向」をＸ軸方向とし、押付部３から見て端子部２側となる向きをＸ軸の正（プラス）の向きとして説明する。また、Ｘ軸方向と直交し、かつ電線１００が挿入される方向である「挿入方向」をＹ軸方向とし、電線１００が挿入される向きをＹ軸の正の向きとして説明する。さらに、Ｘ軸とＹ軸との両方に直交し、かつ端子装置１に接続される２本の電線１００が並ぶ方向である「幅方向」（図１Ｂの紙面に直交する方向）をＺ軸方向とし、図１Ｂの紙面の手前側をＺ軸の正の向きとして説明する。ただし、これらの方向は端子装置１の使用方向を限定する趣旨ではない。また、図面中のＸ軸、Ｙ軸及びＺ軸の各方向を示す矢印は説明のために表記しているに過ぎず、実体を伴わない。また、本開示で用いる「直交」は、厳密に９０度で交わる状態だけでなく、ある程度の誤差の範囲内で略直交する状態も含む意味である。さらに、対向方向と挿入方向とが直交していることは端子装置１に必須の構成ではなく、対向方向と挿入方向とは交差していればよい。 In the following, the “facing direction”, which is the direction in which the terminal portion 2 and the pressing portion 3 face each other, is defined as the X-axis direction, and the direction toward the terminal portion 2 when viewed from the pressing portion 3 is the positive (plus) direction of the X axis. Will be described. In addition, the “insertion direction” that is orthogonal to the X-axis direction and the direction in which the electric wire 100 is inserted is defined as the Y-axis direction, and the direction in which the electric wire 100 is inserted is described as the positive direction of the Y-axis. Further, the “width direction” (the direction perpendicular to the paper surface of FIG. 1B), which is the direction in which the two electric wires 100 connected to the terminal device 1 are aligned, is orthogonal to both the X axis and the Y axis. The front side of the paper surface of FIG. 1B will be described as the positive direction of the Z axis. However, these directions are not intended to limit the use direction of the terminal device 1. In addition, the arrows indicating the directions of the X axis, the Y axis, and the Z axis in the drawings are merely shown for the sake of explanation, and are not accompanied by an entity. Further, “orthogonal” used in the present disclosure is meant to include not only a state of intersecting at an exact 90 degrees but also a state of being approximately orthogonal within a certain error range. Furthermore, it is not essential for the terminal device 1 that the facing direction and the insertion direction are orthogonal to each other, and the facing direction and the insertion direction only need to intersect.
　本実施形態に係る端子装置１は、電線１００を２本まで接続可能な２極型の端子装置である。すなわち、端子装置１は、挿入口１１が２つあり、これら２つの挿入口１１を通して２本の電線１００を同時に接続可能である。この端子装置１では、２本の電線１００は１つの端子部２に対して電気的に接続されるため、端子装置１に接続される２本の電線１００は端子部２を介して互いに電気的に接続されることになる。したがって、端子装置１は、例えば送り端子として用いられる。 The terminal device 1 according to the present embodiment is a two-pole type terminal device that can connect up to two electric wires 100. That is, the terminal device 1 has two insertion ports 11, and two electric wires 100 can be simultaneously connected through the two insertion ports 11. In this terminal device 1, since the two electric wires 100 are electrically connected to the one terminal portion 2, the two electric wires 100 connected to the terminal device 1 are electrically connected to each other via the terminal portion 2. Will be connected to. Therefore, the terminal device 1 is used as a feed terminal, for example.
　端子装置１は、端子ブロック１２と、ばねブロック１３との２つの部材を備えている。端子ブロック１２及びばねブロック１３は別個の部材である。つまり、端子ブロック１２及びばねブロック１３は、互いに切り離され独立した部材である。端子ブロック１２には、端子部２及び押付部３が含まれている。ばねブロック１３には、鎖錠部４が含まれている。端子ブロック１２は、導電性を有する金属板からなる。ばねブロック１３は、弾性を有する金属板からなる。端子ブロック１２（押付部３）とばねブロック１３（鎖錠部４）とは、互いに異なる材料で構成されている。ばねブロック１３は、端子ブロック１２に囲まれた空間に収容されるように、端子ブロック１２と組み合わされる。 The terminal device 1 includes two members, a terminal block 12 and a spring block 13.

The facing portion 5 forms an accommodating space 50 in which the pressing portion 3 and the locking portion 4 are accommodated between the facing portion 5 and the terminal portion 2. The side wall portion 6 connects the terminal portion 2 and the facing portion 5. The side wall portion 6 connects at least one end portions in the Z-axis direction of the terminal portion 2 and the facing portion 5. That is, the terminal portion 2 and the facing portion 5 are connected to each other at the one end portion in the Z-axis direction by the side wall portion 6.
　また、連結部３０は、端子部２と押付部３とを連結する。連結部３０は、端子部２のうち、Ｙ軸方向における挿入口１１とは反対側の端部と、押付部３とを連結している。つまり、端子部２及び押付部３は、Ｙ軸方向における挿入口１１とは反対側の端部（図１Ｂでは上端部）同士が、連結部３０にて互いに連結されている。 Further, the connecting part 30 connects the terminal part 2 and the pressing part 3. The connecting portion 30 connects the pressing portion 3 and the end portion of the terminal portion 2 on the side opposite to the insertion port 11 in the Y-axis direction. That is, the terminal portion 2 and the pressing portion 3 are connected to each other at the end portion (upper end portion in FIG. 1B) opposite to the insertion port 11 in the Y-axis direction by the connecting portion 30.
　端子ブロック１２は、例えば銅（Ｃｕ）からなる。本実施形態では、端子装置１は２極型の端子装置であって、押付部３、側壁部６及び連結部３０は複数（ここでは２つ）ずつ設けられている。ただし、端子装置１は、２つの押付部３（又は、２つの側壁部６若しくは２つの連結部３０）が並ぶＺ軸方向において、面対称となる構成を採用している。そのため、以下では、特に断りがない限り、２つの押付部３のうちの一方の押付部３について説明し、他方の押付部３についての説明は適宜省略する。同様に、２つの側壁部６のうちの一方の側壁部６について説明し、他方の側壁部６についての説明は適宜省略する。さらに、２つの連結部３０のうちの一方の連結部３０について説明し、他方の連結部３０についての説明は適宜省略する。 The terminal block 12 is made of, for example, copper (Cu). In this embodiment, the terminal device 1 is a two-pole terminal device, and a plurality of (here, two) pressing parts 3, side wall parts 6, and connecting parts 30 are provided. However, the terminal device 1 employs a configuration that is plane-symmetric in the Z-axis direction in which the two pressing portions 3 (or the two side wall portions 6 or the two connecting portions 30) are arranged. Therefore, unless otherwise specified, one of the two pressing parts 3 will be described below, and the description of the other pressing part 3 will be omitted as appropriate. Similarly, one side wall part 6 of the two side wall parts 6 will be described, and description of the other side wall part 6 will be omitted as appropriate. Further, one of the two connecting portions 30 will be described, and the description of the other connecting portion 30 will be omitted as appropriate.
　ここでは、端子部２と押付部３と対向部５と側壁部６と連結部３０とは一体に形成されている。言い換えれば、端子部２と、２つの押付部３と、対向部５と、２つの側壁部６と、２つの連結部３０とは、１枚の金属板からなる。本実施形態では、端子ブロック１２を構成する端子部２、押付部３、対向部５、側壁部６、及び連結部３０は、１枚の金属板に打ち抜き加工及び曲げ加工が施されることにより形成されている。 Here, the terminal portion 2, the pressing portion 3, the facing portion 5, the side wall portion 6, and the connecting portion 30 are integrally formed. In other words, the terminal part 2, the two pressing parts 3, the facing part 5, the two side wall parts 6, and the two connecting parts 30 are made of a single metal plate. In this embodiment, the terminal part 2, the pressing part 3, the opposing part 5, the side wall part 6, and the connection part 30 which comprise the terminal block 12 are stamped and bent to one metal plate. Is formed.
　端子部２は、矩形板状である。端子部２は、厚み方向（Ｘ軸方向）の一表面２０を押付部３と対向させるように構成されている。つまり、挿入口１１から挿入される電線１００は、端子部２の一表面２０と押付部３との間に導入され、端子部２の一表面２０に接触するようにして、端子部２と電気的に接続される。 The terminal part 2 has a rectangular plate shape. The terminal portion 2 is configured so that one surface 20 in the thickness direction (X-axis direction) faces the pressing portion 3. That is, the electric wire 100 inserted from the insertion port 11 is introduced between the one surface 20 of the terminal portion 2 and the pressing portion 3 so as to come into contact with the one surface 20 of the terminal portion 2 so as to be electrically connected to the terminal portion 2. Connected.
　また、端子部２におけるＺ軸方向の中央部には、端子部２を厚み方向に貫通するスリット２３が、Ｙ軸方向に沿って形成されている。スリット２３は、端子部２のＹ軸方向の両端間にわたって形成されている。言い換えれば、端子部２は、スリット２３によってＺ軸方向に二分されている。このスリット２３を通して、後述する解除部材９の一部が、端子部２と対向部５との間の収容空間５０に挿入される。 Further, a slit 23 penetrating the terminal portion 2 in the thickness direction is formed along the Y-axis direction in the center portion of the terminal portion 2 in the Z-axis direction. The slit 23 is formed across both ends of the terminal portion 2 in the Y-axis direction. In other words, the terminal portion 2 is divided into two in the Z-axis direction by the slit 23. Through this slit 23, a part of the release member 9 described later is inserted into the accommodation space 50 between the terminal portion 2 and the facing portion 5.
　対向部５は、端子部２の一表面２０と対向する位置に配置されている。対向部５は、矩形板状であって、厚み方向（Ｘ軸方向）の一表面からなる内側面５１を、端子部２の一表面２０に対向させるように構成されている。ここでは、対向部５の内側面５１と、端子部２の一表面２０とは、互いに平行する。これにより、対向部５の内側面５１と端子部２の一表面２０との間には、押付部３及び鎖錠部４を収容するための収容空間５０が形成される。詳しくは「（２．３）ばねブロック」の欄で説明するが、対向部５は、内側面５１にて、ばねブロック１３の位置決めを行う。 The facing portion 5 is disposed at a position facing the one surface 20 of the terminal portion 2. The facing portion 5 has a rectangular plate shape and is configured so that the inner side surface 51 formed of one surface in the thickness direction (X-axis direction) faces the one surface 20 of the terminal portion 2. Here, the inner surface 51 of the facing portion 5 and the one surface 20 of the terminal portion 2 are parallel to each other. Thereby, an accommodation space 50 for accommodating the pressing portion 3 and the locking portion 4 is formed between the inner side surface 51 of the facing portion 5 and the one surface 20 of the terminal portion 2. The details will be described in the column “(2.3) Spring block”, but the facing portion 5 positions the spring block 13 on the inner surface 51.
　側壁部６は、矩形板状である。本実施形態では、対向部５のＺ軸方向の両端部から、２つの側壁部６がＸ軸の正の向きに突出し、各側壁部６の先端部が端子部２に繋がっている。つまり、２つの側壁部６は、端子部２及び対向部５におけるＺ軸方向の両端部同士を、それぞれ連結する。２つの側壁部６は、厚み方向（Ｚ軸方向）の一表面からなる内側面６０同士を互いに対向させるように構成されている。ここでは、一方の側壁部６の内側面６０と、他方の側壁部６の内側面６０とは、互いに平行する。これにより、２つの側壁部６の一対の内側面６０の間には、収容空間５０が形成される。 The side wall portion 6 has a rectangular plate shape. In the present embodiment, the two side wall portions 6 protrude in the positive direction of the X axis from both end portions of the facing portion 5 in the Z-axis direction, and the tip portions of the side wall portions 6 are connected to the terminal portion 2. That is, the two side wall portions 6 connect both end portions of the terminal portion 2 and the facing portion 5 in the Z-axis direction, respectively. The two side wall portions 6 are configured so that the inner side surfaces 60 formed of one surface in the thickness direction (Z-axis direction) face each other. Here, the inner side surface 60 of one side wall part 6 and the inner side surface 60 of the other side wall part 6 are parallel to each other. Thereby, an accommodation space 50 is formed between the pair of inner side surfaces 60 of the two side wall portions 6.
　以下では、端子ブロック１２のうち、押付部３及び連結部３０を除く部分を「筒状体１２０」という。つまり、筒状体１２０は、図２に示すように、端子部２と押付部３と対向部５と側壁部６とで構成される。 Hereinafter, a portion of the terminal block 12 excluding the pressing portion 3 and the connecting portion 30 is referred to as a “tubular body 120”. That is, as shown in FIG. 2, the cylindrical body 120 includes the terminal portion 2, the pressing portion 3, the facing portion 5, and the side wall portion 6.
　本実施形態においては、筒状体１２０は、曲げ加工により、１枚の金属板から、Ｙ軸方向に延びた角筒状に形成されている。筒状体１２０のうち、Ｘ軸方向に対向する一対の側板は、端子部２及び対向部５によって構成され、Ｚ軸方向に対向する一対の側板は、２つの側壁部６によって構成されている。本実施形態では、端子部２と側壁部６との間の連結部分（第１角部６１）、及び対向部５と側壁部との間の連結部分（第２角部６２）は、いずれも所定の曲率半径で湾曲している。 In the present embodiment, the cylindrical body 120 is formed into a rectangular cylinder extending in the Y-axis direction from one metal plate by bending. In the cylindrical body 120, a pair of side plates facing in the X-axis direction is configured by the terminal portion 2 and the facing portion 5, and a pair of side plates facing in the Z-axis direction is configured by the two side wall portions 6. . In the present embodiment, the connecting portion (first corner portion 61) between the terminal portion 2 and the side wall portion 6 and the connecting portion (second corner portion 62) between the facing portion 5 and the side wall portion are both. It is curved with a predetermined radius of curvature.
　言い換えれば、帯状の金属板を、Ｙ軸方向の両面が開放された筒状に加工することによって、端子部２、対向部５、及び側壁部６が形成される。そして、端子部２の一表面２０、対向部５の内側面５１、及び側壁部６の内側面６０とで囲まれた空間、つまり筒状体１２０の内側の空間が、収容空間５０を構成する。よって、押付部３及び鎖錠部４は、筒状体１２０の内側に収容されることになる。 In other words, the terminal portion 2, the facing portion 5, and the side wall portion 6 are formed by processing the belt-shaped metal plate into a cylindrical shape with both sides in the Y-axis direction being opened. The space surrounded by the one surface 20 of the terminal portion 2, the inner side surface 51 of the facing portion 5, and the inner side surface 60 of the side wall portion 6, that is, the space inside the cylindrical body 120 constitutes the accommodation space 50. . Therefore, the pressing part 3 and the locking part 4 are accommodated inside the cylindrical body 120.
　さらに、筒状体１２０の周方向の一部には、筒状体１２０のＹ軸方向の全長にわたってスリット２３が形成されている。つまり、筒状体１２０は、完全な角筒ではなく、周方向の一部に形成されたスリット２３によって、周方向に分断されている。筒状体１２０を構成する金属板の展開状態における両端部は、筒状体１２０においては、端子部２のうちスリット２３を挟んで対向する部分に相当する。 Furthermore, a slit 23 is formed in a part of the cylindrical body 120 in the circumferential direction over the entire length of the cylindrical body 120 in the Y-axis direction. That is, the cylindrical body 120 is not a complete square tube, but is divided in the circumferential direction by the slits 23 formed in a part in the circumferential direction. Both end portions of the expanded state of the metal plate constituting the cylindrical body 120 correspond to portions of the terminal portion 2 that face each other across the slit 23 in the terminal portion 2.
　また、筒状体１２０のうち、Ｙ軸方向における挿入口１１側の端面に形成された開口部１２１は、開口形状が矩形状である。開口部１２１は、挿入口１１から挿入される電線１００を、筒状体１２０に囲まれた空間（収容空間５０）へ通すための孔である。さらに、詳しくは「（２．６）全体構成」の欄で説明するが、開口部１２１は、端子ブロック１２とばねブロック１３とを組み合わせる際に、収容空間５０にばねブロック１３を導入するための孔となる。 Moreover, the opening part 121 formed in the end surface by the side of the insertion port 11 in the Y-axis direction among the cylindrical bodies 120 has a rectangular opening shape. The opening 121 is a hole for passing the electric wire 100 inserted from the insertion port 11 to a space (accommodating space 50) surrounded by the cylindrical body 120. Further, as will be described in detail in the section of “(2.6) Overall configuration”, the opening 121 is used for introducing the spring block 13 into the accommodation space 50 when the terminal block 12 and the spring block 13 are combined. It becomes a hole.
　対向部５と端子部２とでは、Ｚ軸方向において略同等の長さとなるように寸法関係が規定されている。また、側壁部６のＸ軸方向の寸法は、対向部５（又は端子部２）のＺ軸方向の寸法に比べて、やや短い。さらに、対向部５と端子部２とでは、Ｙ軸方向において端子部２の方が短くなるように寸法関係が規定されている。対向部５と側壁部６とでは、Ｙ軸方向において略同等の長さとなるように寸法関係が規定されている。ここで、筒状体１２０のうちＹ軸方向における挿入口１１側の端縁（図１Ｂでは下端縁）は、端子部２と対向部５と側壁部６とでＹ軸方向の位置が揃っている。そのため、筒状体１２０のうちＹ軸方向における挿入口１１とは反対側の端縁（図１Ｂでは上端縁）は、端子部２に比べて、対向部５及び側壁部６がＹ軸の正の向きに突出した形状となる。 In the facing portion 5 and the terminal portion 2, the dimensional relationship is defined so as to have substantially the same length in the Z-axis direction. Moreover, the dimension of the side wall part 6 in the X-axis direction is slightly shorter than the dimension of the facing part 5 (or the terminal part 2) in the Z-axis direction. Furthermore, the dimensional relationship is defined between the facing portion 5 and the terminal portion 2 so that the terminal portion 2 is shorter in the Y-axis direction. The opposing part 5 and the side wall part 6 have a dimensional relationship defined so as to have substantially the same length in the Y-axis direction. Here, the end edge (the lower end edge in FIG. 1B) on the insertion port 11 side in the Y-axis direction of the cylindrical body 120 is aligned in the Y-axis direction at the terminal portion 2, the facing portion 5, and the side wall portion 6. Yes. Therefore, the end of the cylindrical body 120 opposite to the insertion port 11 in the Y-axis direction (the upper end edge in FIG. 1B) has the opposite portion 5 and the side wall 6 in the positive direction of the Y-axis as compared to the terminal portion 2. The shape protrudes in the direction of.
　押付部３は、筒状体１２０の内側に形成された収容空間５０に配置される。押付部３は、端子部２の一表面２０における第１部位２１と、Ｘ軸方向（対向方向）に対向する位置に配置されている。ここでいう第１部位２１は、端子部２の一表面２０のうちで押付部３と対向する部位である。押付部３は、挿入口１１からＹ軸方向に沿って挿入される電線１００を、第１部位２１との間に挟み込むように構成されている。言い換えれば、挿入口１１から挿入された電線１００が、端子部２の一表面２０と押付部３との間に導入された状態で、押付部３は電線１００に対して一表面２０に押し付ける向きの力を作用させる。つまり、電線１００は、押付部３によって端子部２の一表面２０の第１部位２１に押し付けられることになり、端子部２と電線１００との間に適度な接触圧が生じる。 The pressing portion 3 is disposed in the accommodation space 50 formed inside the cylindrical body 120. The pressing portion 3 is disposed at a position facing the first portion 21 on the one surface 20 of the terminal portion 2 in the X-axis direction (opposing direction). Here, the first portion 21 is a portion facing the pressing portion 3 in the one surface 20 of the terminal portion 2. The pressing portion 3 is configured to sandwich the electric wire 100 inserted along the Y-axis direction from the insertion port 11 between the first portion 21. In other words, the direction in which the pressing portion 3 presses the electric wire 100 against the one surface 20 in a state where the electric wire 100 inserted from the insertion port 11 is introduced between the one surface 20 of the terminal portion 2 and the pressing portion 3. Apply the power of. That is, the electric wire 100 is pressed against the first portion 21 of the one surface 20 of the terminal portion 2 by the pressing portion 3, and an appropriate contact pressure is generated between the terminal portion 2 and the electric wire 100.
　押付部３は、第１押付片３１と、第２押付片３２と、第３押付片３３とを有している。これら第１押付片３１、第２押付片３２及び第３押付片３３は、連結部３０側（つまり挿入口１１とは反対側）から、第１押付片３１、第２押付片３２、第３押付片３３の順に、Ｙ軸方向に並んでいる。 The pressing part 3 includes a first pressing piece 31, a second pressing piece 32, and a third pressing piece 33. The first pressing piece 31, the second pressing piece 32, and the third pressing piece 33 are connected to the first pressing piece 31, the second pressing piece 32, the third pressing piece from the connecting portion 30 side (that is, the side opposite to the insertion port 11). The pressing pieces 33 are arranged in the Y-axis direction in this order.
　第１押付片３１は、矩形板状であって、端子部２の一表面２０に略平行する。第１押付片３１のうち、Ｙ軸方向における挿入口１１とは反対側の端部は、連結部３０に繋がっている。第１押付片３１のうち、Ｙ軸方向における挿入口１１側の端部には、第２押付片３２が繋がっている。第２押付片３２は、矩形板状であって、Ｙ軸方向において挿入口１１に近づくほど端子部２に近づくように、端子部２の一表面２０に対して傾斜している。第２押付片３２のうち、Ｙ軸方向における第１押付片３１とは反対側の端部には、第３押付片３３が繋がっている。第３押付片３３は、矩形板状であって、Ｙ軸方向において挿入口１１から離れるほど端子部２に近づくように、端子部２の一表面２０に対して傾斜している。 The first pressing piece 31 has a rectangular plate shape and is substantially parallel to the one surface 20 of the terminal portion 2. Of the first pressing piece 31, the end portion on the opposite side to the insertion port 11 in the Y-axis direction is connected to the connecting portion 30. A second pressing piece 32 is connected to an end of the first pressing piece 31 on the insertion port 11 side in the Y-axis direction. The second pressing piece 32 has a rectangular plate shape, and is inclined with respect to the one surface 20 of the terminal portion 2 so as to approach the terminal portion 2 as it approaches the insertion port 11 in the Y-axis direction. A third pressing piece 33 is connected to an end of the second pressing piece 32 on the side opposite to the first pressing piece 31 in the Y-axis direction. The third pressing piece 33 has a rectangular plate shape, and is inclined with respect to the one surface 20 of the terminal portion 2 so as to approach the terminal portion 2 as the distance from the insertion port 11 increases in the Y-axis direction.
　つまり、第３押付片３３は、第２押付片３２と共に、Ｚ軸方向に直交する断面形状が略Ｖ字状の構造を構成する。そして、押付部３は、第２押付片３２と第３押付片３３との連結部分からなる接触部３４において、端子部２の一表面２０に最も近くなる。言い換えれば、押付部３は、Ｘ軸方向及びＹ軸方向の両方を含む平面（Ｘ－Ｙ平面）内で、Ｘ軸方向において端子部２側に凸となるように湾曲した接触部３４を有している。ここでは、接触部３４は、所定の曲率半径で湾曲している。 That is, the third pressing piece 33 and the second pressing piece 32 constitute a structure having a substantially V-shaped cross section perpendicular to the Z-axis direction. Then, the pressing portion 3 is closest to the one surface 20 of the terminal portion 2 in the contact portion 34 formed by the connection portion between the second pressing piece 32 and the third pressing piece 33. In other words, the pressing portion 3 has a contact portion 34 that is curved so as to protrude toward the terminal portion 2 in the X-axis direction within a plane (XY plane) including both the X-axis direction and the Y-axis direction. is doing. Here, the contact portion 34 is curved with a predetermined radius of curvature.
　連結部３０は、端子部２のうち、Ｙ軸方向における挿入口１１とは反対側の端部から、挿入口１１とは反対側に突出している。つまり、端子部２及び押付部３は、Ｙ軸方向における挿入口１１とは反対側の端部（図１Ｂでは上端部）からＹ軸の正の向きに突出するように設けられた連結部３０にて、互いに連結されている。 The connecting portion 30 projects from the end portion of the terminal portion 2 opposite to the insertion port 11 in the Y-axis direction to the opposite side of the insertion port 11. That is, the terminal portion 2 and the pressing portion 3 are provided so that the terminal portion 2 and the pressing portion 3 are provided so as to protrude in the positive direction of the Y axis from the end portion on the opposite side to the insertion port 11 in the Y axis direction (the upper end portion in FIG. 1B). Are connected to each other.
　また、連結部３０は、湾曲部３０１を有している。湾曲部３０１は、Ｘ軸方向及びＹ軸方向の両方を含む平面（Ｘ－Ｙ平面）内で、Ｙ軸方向において挿入口１１とは反対側に凸となるように湾曲している。ここでは、湾曲部３０１は円弧状に湾曲している。湾曲部３０１の内径は、押付部３の第１押付片３１と端子部２との間隔に略一致する。 Further, the connecting part 30 has a curved part 301. The bending portion 301 is curved so as to be convex on the opposite side to the insertion port 11 in the Y-axis direction within a plane (XY plane) including both the X-axis direction and the Y-axis direction. Here, the bending portion 301 is curved in an arc shape. The inner diameter of the bending portion 301 substantially matches the distance between the first pressing piece 31 of the pressing portion 3 and the terminal portion 2.
　さらに本実施形態では、図１Ｂに示すように、Ｙ軸方向において、連結部３０における挿入口１１とは反対側の端部から挿入口１１までの距離Ｌ１０は、対向部５及び側壁部６における挿入口１１とは反対側の端部から挿入口１１までの距離Ｌ１１以下である。ここでは、筒状体１２０のうちＹ軸方向における挿入口１１側の端縁を基準面とし、基準面から、連結部３０における挿入口１１とは反対側の端縁までの距離を距離Ｌ１０、対向部５及び側壁部６における挿入口１１とは反対側の端縁までの距離をＬ１１とする。図１Ｂの例では、距離Ｌ１０は距離Ｌ１１と同一である（Ｌ１０＝Ｌ１１）。 Furthermore, in this embodiment, as shown in FIG. 1B, in the Y-axis direction, the distance L10 from the end of the connecting portion 30 opposite to the insertion port 11 to the insertion port 11 is equal to the distance between the facing portion 5 and the side wall portion 6. The distance from the end opposite to the insertion port 11 to the insertion port 11 is not more than a distance L11. Here, the end of the cylindrical body 120 on the side of the insertion port 11 in the Y-axis direction is used as a reference plane, and the distance from the reference surface to the end of the connecting portion 30 opposite to the insertion port 11 is a distance L10, The distance to the edge on the opposite side to the insertion port 11 in the opposing part 5 and the side wall part 6 is set to L11. In the example of FIG. 1B, the distance L10 is the same as the distance L11 (L10 = L11).
　すなわち、連結部３０は端子部２からＹ軸の正の向きに突出しながらも、対向部５及び側壁部６で囲まれた領域からはみ出さないように、連結部３０の突出量が規定されている。これにより、連結部３０の突出量の分だけ、押付部３が変位する際の支点から押付部３までの距離を大きくして、連結部３０の変形量（撓み量）を小さく抑えながらも、連結部３０が、筒状体１２０の内側に収まることになる。 That is, the protruding amount of the connecting portion 30 is defined so that the connecting portion 30 protrudes from the terminal portion 2 in the positive direction of the Y axis but does not protrude from the region surrounded by the facing portion 5 and the side wall portion 6. Yes. As a result, while the distance from the fulcrum when the pressing portion 3 is displaced to the pressing portion 3 is increased by the amount of protrusion of the connecting portion 30, the deformation amount (deflection amount) of the connecting portion 30 is kept small. The connecting part 30 is accommodated inside the cylindrical body 120.
　上述したような構成の押付部３及び連結部３０は、筒状体１２０と一体に形成され、筒状体１２０と共に端子ブロック１２を構成する。ここで、筒状体１２０における端子部２に形成されたスリット２３は、連結部３０を通して第３押付片３３の先端まで延びている。２つの連結部３０は、スリット２３にてＺ軸方向に分離されている。同様に、２つの押付部３は、スリット２３にてＺ軸方向に分離されている。 The pressing portion 3 and the connecting portion 30 configured as described above are formed integrally with the cylindrical body 120 and constitute the terminal block 12 together with the cylindrical body 120. Here, the slit 23 formed in the terminal portion 2 of the cylindrical body 120 extends to the tip of the third pressing piece 33 through the connecting portion 30. The two connecting portions 30 are separated by the slit 23 in the Z-axis direction. Similarly, the two pressing portions 3 are separated by the slit 23 in the Z-axis direction.
　（２．３）ばねブロック
　ばねブロック１３は、図１Ａ～図３Ｂに示すように、鎖錠部４に加えて、延出部７を有している。ばねブロック１３は、例えばステンレス鋼（ＳＵＳ）からなる。ばねブロック１３は、端子ブロック１２よりも厚みの小さい（薄い）金属板にて構成されている。本実施形態では、端子装置１は２極型の端子装置であって、鎖錠部４は複数（ここでは２つ）設けられている。ただし、端子装置１は、２つの鎖錠部４が並ぶＺ軸方向において、面対称となる構成を採用している。そのため、以下では、特に断りがない限り、２つの鎖錠部４のうちの一方の鎖錠部４について説明し、他方の鎖錠部４についての説明は適宜省略する。 (2.3) Spring Block As shown in FIGS. 1A to 3B, the spring block 13 has an extending portion 7 in addition to the locking portion 4. The spring block 13 is made of, for example, stainless steel (SUS). The spring block 13 is composed of a metal plate that is thinner (thin) than the terminal block 12. In this embodiment, the terminal device 1 is a two-pole type terminal device, and a plurality (two in this case) of the locking portions 4 are provided. However, the terminal device 1 employs a configuration that is plane-symmetric in the Z-axis direction in which the two locking portions 4 are arranged. Therefore, hereinafter, unless otherwise specified, one of the two lock portions 4 will be described, and the description of the other lock portion 4 will be omitted as appropriate.
　ここでは、鎖錠部４と延出部７とは一体に形成されている。言い換えれば、２つの鎖錠部４と、延出部７とは、１枚の金属板からなる。本実施形態では、ばねブロック１３を構成する鎖錠部４及び延出部７は、１枚の金属板に打ち抜き加工及び曲げ加工が施されることにより形成されている。 Here, the lock part 4 and the extension part 7 are integrally formed. In other words, the two locking portions 4 and the extending portion 7 are made of a single metal plate. In this embodiment, the lock part 4 and the extension part 7 which comprise the spring block 13 are formed by stamping and bending to one metal plate.
　鎖錠部４は、筒状体１２０の内側に形成された収容空間５０に配置される。鎖錠部４は、端子部２の一表面２０における第２部位２２と、Ｘ軸方向（対向方向）に対向する位置に配置されている。ここでいう第２部位２２は、端子部２の一表面２０のうちで、Ｙ軸方向において第１部位２１とは異なる部位であって、鎖錠部４と対向する部位である。Ｙ軸方向において、第１部位２１と挿入口１１との間に第２部位２２が位置する。つまり、第１部位２１及び第２部位２２は、挿入口１１側から、第２部位２２、第１部位２１の順に、Ｙ軸方向に並んでいる。 The lock part 4 is disposed in a storage space 50 formed inside the cylindrical body 120. The locking part 4 is arranged at a position facing the second part 22 on the one surface 20 of the terminal part 2 in the X-axis direction (opposing direction). The second portion 22 here is a portion that is different from the first portion 21 in the Y-axis direction on the one surface 20 of the terminal portion 2, and is a portion that faces the locking portion 4. In the Y-axis direction, the second portion 22 is located between the first portion 21 and the insertion port 11. That is, the first part 21 and the second part 22 are arranged in the Y-axis direction in the order of the second part 22 and the first part 21 from the insertion port 11 side.
　鎖錠部４は、挿入口１１からＹ軸方向に沿って挿入される電線１００に接触して、電線１００の挿入口１１側への移動を規制するように構成されている。言い換えれば、挿入口１１から挿入された電線１００が、端子部２の一表面２０と鎖錠部４との間に導入された状態で、鎖錠部４は第２部位２２との間に電線１００を挟み込むように構成されている。つまり、電線１００は、鎖錠部４によって端子部２の一表面２０の第２部位２２に押し付けられることになり、端子部２と電線１００との間に適度な接触圧が生じる。 The locking part 4 is configured to contact the electric wire 100 inserted along the Y-axis direction from the insertion port 11 and to restrict the movement of the electric wire 100 toward the insertion port 11. In other words, in a state where the electric wire 100 inserted from the insertion port 11 is introduced between the one surface 20 of the terminal portion 2 and the lock portion 4, the lock portion 4 is between the second portion 22 and the electric wire 100. It is comprised so that 100 may be inserted | pinched. That is, the electric wire 100 is pressed against the second portion 22 of the one surface 20 of the terminal portion 2 by the locking portion 4, and an appropriate contact pressure is generated between the terminal portion 2 and the electric wire 100.
　ここでは、鎖錠部４は、矩形板状であって、Ｙ軸方向において挿入口１１から離れるほど端子部２に近づくように、端子部２の一表面２０に対して傾斜している。そして、鎖錠部４は、端子部２の一表面２０に最も近い先端縁４１にて、電線１００に接触して電線１００の挿入口１１側への移動を規制する。つまり、鎖錠部４は、延出部７との連結部分（ばね部４２）から、電線１００が挿入される向き（Ｙ軸の正の向き）に突出しており、その先端縁４１を端子部２の一表面２０に近づけるように、端子部２の一表面２０に対して傾斜している。そして、電線１００が、端子部２の一表面２０と鎖錠部４との間に導入された状態では、鎖錠部４は、先端縁４１にて電線１００と接触する。そのため、電線１００に対して、電線１００を挿入口１１側へ移動させる向き（Ｙ軸の負の向き）の力が作用すると、鎖錠部４の先端縁４１が電線１００に食い込むように、鎖錠部４が電線１００に引っ掛かることによって、電線１００の抜け止めがなされる。 Here, the lock part 4 is a rectangular plate shape, and is inclined with respect to the one surface 20 of the terminal part 2 so as to approach the terminal part 2 as the distance from the insertion port 11 increases in the Y-axis direction. And the lock | rock part 4 contacts the electric wire 100 in the front-end edge 41 nearest to the one surface 20 of the terminal part 2, and controls the movement to the insertion port 11 side of the electric wire 100. FIG. That is, the locking part 4 protrudes from the connection part (spring part 42) with the extension part 7 in the direction in which the electric wire 100 is inserted (the positive direction of the Y axis), and the tip edge 41 is connected to the terminal part. 2 is inclined with respect to the one surface 20 of the terminal portion 2 so as to be close to the one surface 20. In a state where the electric wire 100 is introduced between the one surface 20 of the terminal portion 2 and the locking portion 4, the locking portion 4 comes into contact with the electric wire 100 at the tip edge 41. Therefore, when a force in the direction of moving the electric wire 100 toward the insertion port 11 is applied to the electric wire 100 (the negative direction of the Y-axis), the chain is set so that the leading edge 41 of the locking portion 4 bites into the electric wire 100. When the lock part 4 is hooked on the electric wire 100, the electric wire 100 is prevented from coming off.
　延出部７は、図３Ａ及び図３Ｂに示すように、鎖錠部４のうち、Ｙ軸方向における挿入口１１側の端部（図３Ａでは下端部）から、挿入口１１とは反対側に突出している。つまり、ばねブロック１３のうち、鎖錠部４における先端縁４１とは反対側の端部から、Ｙ軸の正の向きに延びた部分が延出部７を構成する。鎖錠部４と延出部７との連結部分からなるばね部４２は、鎖錠部４に対して弾性力を作用させる。言い換えれば、ばねブロック１３は、Ｘ軸方向及びＹ軸方向の両方を含む平面（Ｘ－Ｙ平面）内で、Ｙ軸方向において挿入口１１側に凸となるように湾曲したばね部４２を有している。ここでは、ばね部４２は、所定の曲率半径で湾曲している。 As shown in FIGS. 3A and 3B, the extension portion 7 is opposite to the insertion port 11 from the end portion (the lower end portion in FIG. 3A) on the insertion port 11 side in the Y-axis direction of the locking portion 4. Protruding. That is, a portion of the spring block 13 that extends in the positive direction of the Y axis from the end of the lock portion 4 opposite to the tip edge 41 constitutes the extension portion 7. The spring portion 42, which is a connecting portion between the locking portion 4 and the extending portion 7, exerts an elastic force on the locking portion 4. In other words, the spring block 13 has a spring portion 42 that is curved so as to protrude toward the insertion port 11 in the Y-axis direction within a plane (XY plane) that includes both the X-axis direction and the Y-axis direction. is doing. Here, the spring part 42 is curved with a predetermined radius of curvature.
　延出部７は、第１延出片７１と、第２延出片７２とを有している。これら第１延出片７１及び第２延出片７２は、鎖錠部４側から、第１延出片７１、第２延出片７２の順に、繋がっている。 The extending part 7 has a first extending piece 71 and a second extending piece 72. The first extending piece 71 and the second extending piece 72 are connected in the order of the first extending piece 71 and the second extending piece 72 from the side of the lock portion 4.
　第１延出片７１は、矩形板状であって、端子部２の一表面２０に略平行する。第１延出片７１のうち、Ｙ軸方向における挿入口１１側の端部は、鎖錠部４に繋がっている。第１延出片７１のうち、Ｙ軸方向における鎖錠部４とは反対側の端部は、第２延出片７２に繋がっている。第２延出片７２は、矩形板状であって、第１延出片７１からＸ軸の正の向きに突出する。第２延出片７２と第１延出片７１とは、互いに略直交する。 The first extending piece 71 has a rectangular plate shape and is substantially parallel to the one surface 20 of the terminal portion 2. Of the first extending piece 71, the end on the insertion port 11 side in the Y-axis direction is connected to the locking part 4. Of the first extending piece 71, the end opposite to the locking part 4 in the Y-axis direction is connected to the second extending piece 72. The second extending piece 72 has a rectangular plate shape and protrudes from the first extending piece 71 in the positive direction of the X axis. The second extending piece 72 and the first extending piece 71 are substantially orthogonal to each other.
　つまり、第２延出片７２は、第１延出片７１と共に、Ｚ軸方向に直交する断面形状が略Ｌ字状の構造を構成する。そして、ばねブロック１３は、第１延出片７１を、対向部５の内側面５１に接触させることにより、端子ブロック１２に対してＸ軸方向における位置決めがなされる。また、ばねブロック１３が、端子ブロック１２と共に、後述するケース８に収納された状態で、第２延出片７２が、ケース８に接触する。これにより、端子ブロック１２に対するばねブロック１３のＹ軸方向における位置決めがなされる。言い換えれば、ばねブロック１３は、第１延出片７１と第２延出片７２との連結部分からなる角部７３を、端子ブロック１２又はケース８に接触させることで、端子ブロック１２に対して位置決めがなされる。角部７３は、所定の曲率半径で湾曲している。 That is, the second extending piece 72 and the first extending piece 71 constitute a structure having a substantially L-shaped cross section perpendicular to the Z-axis direction. The spring block 13 is positioned with respect to the terminal block 12 in the X-axis direction by bringing the first extending piece 71 into contact with the inner side surface 51 of the facing portion 5. Further, the second extension piece 72 contacts the case 8 in a state where the spring block 13 is housed in the case 8 described later together with the terminal block 12. As a result, the spring block 13 is positioned with respect to the terminal block 12 in the Y-axis direction. In other words, the spring block 13 contacts the terminal block 12 or the case 8 with the corner portion 73 formed by the connecting portion of the first extending piece 71 and the second extending piece 72, so that the spring block 13 is in contact with the terminal block 12. Positioning is done. The corner 73 is curved with a predetermined radius of curvature.
　ここで、ばねブロック１３のＹ軸方向の寸法は、端子ブロック１２における対向部５のＹ軸方向の寸法以下に規定されている。図１Ｂの例では、ばねブロック１３のＹ軸方向の寸法は、端子ブロック１２における対向部５のＹ軸方向の寸法と同一である。また、ばねブロック１３のＸ軸方向の寸法は、端子ブロック１２における端子部２と対向部５との間隔よりやや小さく規定されている。さらに、ばねブロック１３のＺ軸方向の寸法は、端子ブロック１２における２つの側壁部６の間隔よりやや小さく規定されている。これにより、ばねブロック１３は、Ｘ軸方向及びＺ軸方向については若干の「あそび」がある状態で、筒状体１２０の内側に形成されている収容空間５０内に収納可能となる。 Here, the dimension in the Y-axis direction of the spring block 13 is defined to be equal to or less than the dimension in the Y-axis direction of the facing portion 5 in the terminal block 12. In the example of FIG. 1B, the dimension in the Y-axis direction of the spring block 13 is the same as the dimension in the Y-axis direction of the facing portion 5 in the terminal block 12. The dimension of the spring block 13 in the X-axis direction is defined to be slightly smaller than the distance between the terminal portion 2 and the facing portion 5 in the terminal block 12. Further, the dimension of the spring block 13 in the Z-axis direction is defined to be slightly smaller than the distance between the two side wall portions 6 in the terminal block 12. As a result, the spring block 13 can be stored in the storage space 50 formed inside the cylindrical body 120 with some “play” in the X-axis direction and the Z-axis direction.
　また、第１延出片７１の中央部には、第１延出片７１を厚み方向に貫通する貫通孔７１１が形成されている。貫通孔７１１は、開口形状が円形状である。さらに、第１延出片７１には、第１延出片７１を厚み方向に貫通し、貫通孔７１１から鎖錠部４に向かって延びるスリット７１２が形成されている。スリット７１２は、ばね部４２を通して鎖錠部４の先端縁４１まで延びている。２つの鎖錠部４は、このスリット７１２にて、Ｚ軸方向に分離されている。Ｚ軸方向におけるスリット７１２の幅は一定ではなく、貫通孔７１１から少なくともばね部４２にかけてのスリット７１２の幅は、鎖錠部４の先端縁４１でのスリット７１２の幅よりも広く設定されている。言い換えれば、ばね部４２のＺ軸方向の寸法は、鎖錠部４の先端縁４１のＺ軸方向の寸法より小さく設定されている。これにより、ばね部４２のＺ軸方向の寸法が鎖錠部４の先端縁４１のＺ軸方向の寸法と同一である場合に比べて、ばね部４２の弾性係数が低くなり、ばね部４２が撓みやすくなる。貫通孔７１１は端子装置１に必須の構成ではなく、貫通孔７１１は省略されてもよい。 Further, a through hole 711 that penetrates the first extending piece 71 in the thickness direction is formed at the center of the first extending piece 71. The through hole 711 has a circular opening shape. Further, the first extension piece 71 is formed with a slit 712 that penetrates the first extension piece 71 in the thickness direction and extends from the through hole 711 toward the lock portion 4. The slit 712 extends through the spring portion 42 to the distal end edge 41 of the lock portion 4. The two lock portions 4 are separated in the Z-axis direction by the slit 712. The width of the slit 712 in the Z-axis direction is not constant, and the width of the slit 712 from the through hole 711 to at least the spring portion 42 is set wider than the width of the slit 712 at the distal end edge 41 of the lock portion 4. . In other words, the dimension of the spring part 42 in the Z-axis direction is set to be smaller than the dimension of the distal end edge 41 of the locking part 4 in the Z-axis direction. Thereby, compared with the case where the dimension of the Z-axis direction of the spring part 42 is the same as the dimension of the front-end edge 41 of the locking part 4 in the Z-axis direction, the elastic coefficient of the spring part 42 becomes low, and the spring part 42 becomes It becomes easy to bend. The through hole 711 is not essential for the terminal device 1, and the through hole 711 may be omitted.
　（２．４）寸法関係
　次に、端子ブロック１２にばねブロック１３が組み合わされた状態での、端子部２、押付部３及び鎖錠部４の寸法関係について、図４Ａを参照して説明する。図４Ａは、図１ＡのＺ２－Ｚ２線断面図である。また、図４Ａでは、電線１００を想像線（２点鎖線）で示している。 (2.4) Dimensional relationship Next, the dimensional relationship of the terminal portion 2, the pressing portion 3, and the locking portion 4 in a state where the spring block 13 is combined with the terminal block 12 will be described with reference to FIG. 4A. . 4A is a cross-sectional view taken along line Z2-Z2 of FIG. 1A. Moreover, in FIG. 4A, the electric wire 100 is shown by the imaginary line (two-dot chain line).
　Ｘ軸方向において、押付部３と第１部位２１との間の距離である第１距離Ｌ１は、鎖錠部４と第２部位２２との間の距離である第２距離Ｌ２よりも大きく設定されている。第１距離Ｌ１は、押付部３のうち端子部２の一表面２０に最も近くなる接触部３４と、端子部２の一表面２０との間の最短距離である。同様に、第２距離Ｌ２は、鎖錠部４のうち端子部２の一表面２０に最も近くなる先端縁４１と、端子部２の一表面２０との間の最短距離である。 In the X-axis direction, the first distance L1 that is the distance between the pressing part 3 and the first part 21 is set larger than the second distance L2 that is the distance between the locking part 4 and the second part 22. Has been. The first distance L <b> 1 is the shortest distance between the contact portion 34 that is closest to the one surface 20 of the terminal portion 2 in the pressing portion 3 and the one surface 20 of the terminal portion 2. Similarly, the second distance L <b> 2 is the shortest distance between the tip edge 41 that is closest to the one surface 20 of the terminal portion 2 in the lock portion 4 and the one surface 20 of the terminal portion 2.
　また、押付部３のうち、Ｙ軸方向における挿入口１１側の端部、つまり第３押付片３３は、Ｙ軸方向において挿入口１１に近づくほど端子部２から離れるように、端子部２の一表面２０に対して傾斜している。すなわち、第３押付片３３は、接触部３４から離れるほどに端子部２から離れるように傾斜しているため、第３押付片３３における接触部３４とは反対側の端縁においては、端子部２からの距離が、接触部３４に比べて大きくなる。ここでは、Ｘ軸方向において、第３押付片３３における接触部３４とは反対側の端縁と、端子部２の一表面２０との間の最短距離を、第３距離Ｌ３と規定する。 In addition, of the pressing portion 3, the end portion on the insertion port 11 side in the Y-axis direction, that is, the third pressing piece 33 is separated from the terminal portion 2 as it approaches the insertion port 11 in the Y-axis direction. It is inclined with respect to the one surface 20. That is, since the third pressing piece 33 is inclined so as to be away from the terminal portion 2 as it is away from the contact portion 34, the terminal portion is provided at the end of the third pressing piece 33 opposite to the contact portion 34. The distance from 2 is larger than that of the contact portion 34. Here, in the X-axis direction, the shortest distance between the edge of the third pressing piece 33 opposite to the contact portion 34 and the one surface 20 of the terminal portion 2 is defined as a third distance L3.
　要するに、第１距離Ｌ１、第２距離Ｌ２及び第３距離Ｌ３の関係では、第２距離Ｌ２よりも第１距離Ｌ１が大きくなり、第１距離Ｌ１よりさらに第３距離Ｌ３が大きくなる（Ｌ２＜Ｌ１＜Ｌ３）。 In short, in relation to the first distance L1, the second distance L2, and the third distance L3, the first distance L1 is larger than the second distance L2, and the third distance L3 is larger than the first distance L1 (L2 < L1 <L3).
　ところで、挿入口１１から挿入される電線１００の線径φＸは、第１距離Ｌ１よりも大きく、第３距離Ｌ３よりも小さいことが好ましい。ここでいう電線１００の線径φＸは、端子装置１に接続可能な電線として規定された電線１００の線径φＸである。電線１００が絶縁電線である場合は、挿入口１１から挿入される心線の直径が線径φＸとなる。第１距離Ｌ１、第２距離Ｌ２、第３距離Ｌ３及び線径φＸの関係では、第２距離Ｌ２よりも第１距離Ｌ１が大きくなり、第１距離Ｌ１よりも線径φＸが大きくなり、線径φＸよりさらに第３距離Ｌ３が大きくなる（Ｌ２＜Ｌ１＜φＸ＜Ｌ３）。なお、ここでいう線径φＸは、挿入口１１から挿入される電線１００の外径（絶縁電線の場合は心線の直径）を意味しており、例えばＩＥＣ（International Electrotechnical Commission）規格等に準拠し、適宜決定される。 Incidentally, the wire diameter φX of the electric wire 100 inserted from the insertion port 11 is preferably larger than the first distance L1 and smaller than the third distance L3. The wire diameter φX of the electric wire 100 here is the wire diameter φX of the electric wire 100 defined as an electric wire that can be connected to the terminal device 1. When the electric wire 100 is an insulated wire, the diameter of the core wire inserted from the insertion port 11 is the wire diameter φX. In relation to the first distance L1, the second distance L2, the third distance L3, and the wire diameter φX, the first distance L1 is larger than the second distance L2, the wire diameter φX is larger than the first distance L1, and the line The third distance L3 becomes larger than the diameter φX (L2 <L1 <φX <L3). The wire diameter φX here means the outer diameter of the electric wire 100 inserted from the insertion port 11 (in the case of an insulated wire, the diameter of the core wire), and conforms to the IEC (International Electrotechnical Commission) standard, for example. And appropriately determined.
　（２．５）電線の接続方法
　次に、上述したような構成の端子装置１に対して電線１００を接続する方法について、図４Ａ及び図４Ｂを参照して説明する。図４Ａ及び図４Ｂは、図１ＡのＺ２－Ｚ２線断面図である。また、図４Ａ及び図４Ｂでは、電線１００を想像線（２点鎖線）で示している。図４Ａは、電線１００が接続されていない状態の端子装置１を示し、図４Ｂは、電線１００が接続された状態の端子装置１を示している。 (2.5) Electric Wire Connection Method Next, a method for connecting the electric wire 100 to the terminal device 1 having the above-described configuration will be described with reference to FIGS. 4A and 4B. 4A and 4B are sectional views taken along line Z2-Z2 of FIG. 1A. Moreover, in FIG. 4A and 4B, the electric wire 100 is shown with the imaginary line (two-dot chain line). FIG. 4A shows the terminal device 1 in a state where the electric wire 100 is not connected, and FIG. 4B shows the terminal device 1 in a state where the electric wire 100 is connected.
　作業者は、接続対象となる電線１００を、端子装置１に対して挿入口１１からＹ軸の正の向きに挿入する。電線１００が挿入されると、電線１００の先端は、まず、鎖錠部４と端子部２（第２部位２２）との間に導入される。ここにおいて、「（２．４）寸法関係」の欄で説明したように、第２距離Ｌ２と電線１００の線径φＸとの間には、「Ｌ２＜φＸ」という寸法関係がある。そのため、鎖錠部４が電線１００の先端に押されて、鎖錠部４の先端縁４１が端子部２の一表面２０から離れる向きに変位する。このとき、ばねブロック１３においては、ばね部４２の曲率半径が小さくなるようにばね部４２が弾性変形する。したがって、電線１００に対しては、鎖錠部４から、電線１００を端子部２に押し付ける向きの力が作用する。 The worker inserts the electric wire 100 to be connected into the terminal device 1 from the insertion port 11 in the positive direction of the Y axis. When the electric wire 100 is inserted, the tip of the electric wire 100 is first introduced between the locking portion 4 and the terminal portion 2 (second portion 22). Here, as described in the column “(2.4) Dimensional Relationship”, there is a dimensional relationship “L2 <φX” between the second distance L2 and the wire diameter φX of the electric wire 100. Therefore, the locking part 4 is pushed by the tip of the electric wire 100, and the leading edge 41 of the locking part 4 is displaced in a direction away from the one surface 20 of the terminal part 2. At this time, in the spring block 13, the spring part 42 is elastically deformed so that the radius of curvature of the spring part 42 becomes small. Therefore, a force in a direction of pressing the electric wire 100 against the terminal portion 2 acts on the electric wire 100 from the lock portion 4.
　この状態から電線１００が更に挿入されると、電線１００の先端は、押付部３と端子部２（第１部位２１）との間に導入される。ここにおいて、「（２．４）寸法関係」の欄で説明したように、第１距離Ｌ１と第３距離Ｌ３と電線１００の線径φＸとの間には、「Ｌ１＜φＸ＜Ｌ３」という寸法関係がある。そのため、電線１００の先端は、第３押付片３３にガイドされて、接触部３４と端子部２との間に誘い込まれることになる。そして、接触部３４が電線１００の先端に押されて押付部３の接触部３４が端子部２の一表面２０から離れる向きに変位する。このとき、端子ブロック１２においては、湾曲部３０１の曲率半径が大きくなるように連結部３０が弾性変形する。したがって、電線１００に対しては、押付部３から、電線１００を端子部２に押し付ける向きの力が作用する。 When the electric wire 100 is further inserted from this state, the tip of the electric wire 100 is introduced between the pressing portion 3 and the terminal portion 2 (first portion 21). Here, as described in the column “(2.4) Dimensional Relationship”, the distance between the first distance L1, the third distance L3, and the wire diameter φX of the electric wire 100 is “L1 <φX <L3”. There is a dimensional relationship. Therefore, the tip of the electric wire 100 is guided by the third pressing piece 33 and is drawn between the contact portion 34 and the terminal portion 2. Then, the contact portion 34 is pushed by the tip of the electric wire 100 and the contact portion 34 of the pressing portion 3 is displaced in a direction away from the one surface 20 of the terminal portion 2. At this time, in the terminal block 12, the connecting portion 30 is elastically deformed so that the radius of curvature of the bending portion 301 is increased. Therefore, a force in a direction of pressing the electric wire 100 against the terminal portion 2 acts on the electric wire 100 from the pressing portion 3.
　要するに、電線１００が所定の位置まで挿入された状態では、電線１００が押付部３にて端子部２の一表面２０（第１部位２１）に押し付けられるので、端子部２と電線１００との間に適度な接触圧が生じ、電線１００と端子部２とが電気的に接続される。さらに、この状態では、鎖錠部４の先端縁４１が電線１００に接触することによって、挿入口１１から電線１００が引き抜かれる向きへの電線１００の移動が規制され、電線１００の抜け止めがなされる。 In short, in a state where the electric wire 100 is inserted to a predetermined position, the electric wire 100 is pressed against the one surface 20 (first portion 21) of the terminal portion 2 by the pressing portion 3, and therefore, between the terminal portion 2 and the electric wire 100. Therefore, an appropriate contact pressure is generated, and the electric wire 100 and the terminal portion 2 are electrically connected. Furthermore, in this state, when the leading edge 41 of the locking portion 4 contacts the electric wire 100, the movement of the electric wire 100 in the direction in which the electric wire 100 is pulled out from the insertion port 11 is restricted, and the electric wire 100 is prevented from coming off. The
　ここにおいて、鎖錠部４の先端縁４１が端子部２の一表面２０から離れる向きに変位したときに、鎖錠部４が押付部３に接触しないように、鎖錠部４と押付部３との位置関係、及び鎖錠部４並びに押付部３の各々の寸法が規定されている。つまり、鎖錠部４の先端縁４１の軌跡上に押付部３が位置しないように、Ｙ軸方向における鎖錠部４及び押付部３の位置関係、及び鎖錠部４並びに押付部３の各々の寸法が規定されている。これにより、電線１００が挿入される際に、鎖錠部４と押付部３とは同時に変位するのではなく、先に鎖錠部４が変位し、その後に押付部３が変位することになる。したがって、鎖錠部４と押付部３とが同時に変位する構成に比べて、電線１００の挿入に必要な力の大きさが小さく抑えられる。このように鎖錠部４が押付部３に接触しないようにしながらも、Ｙ軸方向における第１部位２１と第２部位２２との間の距離は、極力小さいことが好ましい。第１部位２１と第２部位２２との間の距離が小さくなれば、挿入すべき電線１００の長さが短くなって、端子装置１の小型化につながる。 Here, when the leading edge 41 of the locking part 4 is displaced away from the one surface 20 of the terminal part 2, the locking part 4 and the pressing part 3 are prevented so that the locking part 4 does not contact the pressing part 3. And the dimensions of the locking part 4 and the pressing part 3 are defined. That is, the positional relationship between the locking unit 4 and the pressing unit 3 in the Y-axis direction, and the locking unit 4 and the pressing unit 3 so that the pressing unit 3 is not positioned on the locus of the leading edge 41 of the locking unit 4. The dimensions are specified. Thereby, when the electric wire 100 is inserted, the locking part 4 and the pressing part 3 are not displaced simultaneously, but the locking part 4 is displaced first, and then the pressing part 3 is displaced. . Therefore, compared with the structure in which the locking part 4 and the pressing part 3 are displaced simultaneously, the magnitude of the force required for inserting the electric wire 100 can be kept small. As described above, it is preferable that the distance between the first portion 21 and the second portion 22 in the Y-axis direction is as small as possible while preventing the locking portion 4 from contacting the pressing portion 3. If the distance between the 1st site | part 21 and the 2nd site | part 22 becomes small, the length of the electric wire 100 which should be inserted will become short, and it will lead to size reduction of the terminal device 1. FIG.
　（２．６）全体構成
　次に、図５～図７Ｂを参照して、ケース８及び解除部材９を含む、端子装置１の全体構成について説明する。すなわち、端子装置１は、上述した端子ブロック１２及びばねブロック１３に加えて、ケース８及び解除部材９を更に備えている。また、図６Ａ及び図６Ｂは、それぞれ図７ＡのＺ１－Ｚ１線斜視断面図である。図７Ｂは、図７ＡのＺ２－Ｚ２線断面図である。また、図７Ｂでは、後述する空隙ＳＰ１を１点鎖線で示しているが、空隙ＳＰ１は説明のために表記しているに過ぎず、実体を伴わない。 (2.6) Overall Configuration Next, the overall configuration of the terminal device 1 including the case 8 and the release member 9 will be described with reference to FIGS. 5 to 7B. That is, the terminal device 1 further includes a case 8 and a release member 9 in addition to the terminal block 12 and the spring block 13 described above. 6A and 6B are perspective sectional views taken along the line Z1-Z1 of FIG. 7A, respectively. 7B is a cross-sectional view taken along the line Z2-Z2 of FIG. 7A. Moreover, in FIG. 7B, although the space | gap SP1 mentioned later is shown with the dashed-dotted line, the space | gap SP1 is only described for description and does not accompany a substance.
　ケース８は、電気絶縁性を有する材料、例えば合成樹脂にて構成されている。ケース８は、端子ブロック１２及びばねブロック１３を収納する空間を有する箱状に形成されている。端子ブロック１２及びばねブロック１３がケース８に収納された状態で、少なくとも筒状体１２０がケース８に対して固定される。図５～図７Ｂでは、ケース８として、Ｙ軸の正の向きに開放された端子室８０を有する、箱状のボディのみを図示している。ただし、ケース８は、端子室８０の開口面を塞ぐようにボディと結合されるカバーを、更に備えている。つまり、端子ブロック１２及びばねブロック１３が端子室８０に収納された状態で、端子室８０の開口面がカバーによって塞がれる。そのため、ばねブロック１３は、第２延出片７２をカバーに接触させることにより、端子ブロック１２に対してＹ軸方向における位置決めがなされる。 Case 8 is made of an electrically insulating material, for example, a synthetic resin. The case 8 is formed in a box shape having a space for accommodating the terminal block 12 and the spring block 13. In a state where the terminal block 12 and the spring block 13 are housed in the case 8, at least the cylindrical body 120 is fixed to the case 8. 5 to 7B, as the case 8, only a box-shaped body having a terminal chamber 80 opened in the positive direction of the Y-axis is illustrated. However, the case 8 further includes a cover coupled to the body so as to close the opening surface of the terminal chamber 80. That is, in a state where the terminal block 12 and the spring block 13 are accommodated in the terminal chamber 80, the opening surface of the terminal chamber 80 is closed by the cover. Therefore, the spring block 13 is positioned in the Y-axis direction with respect to the terminal block 12 by bringing the second extending piece 72 into contact with the cover.
　ケース８のうち挿入口１１に対応する位置には、ケース８の底板をＹ軸方向に貫通する挿入孔８１が形成されている。挿入孔８１は、開口形状が円形状であり、２本の電線１００に対応するように２つ形成されている。挿入孔８１の内径は一定ではなく、電線１００を誘い込むように、Ｙ軸方向の一部において、挿入孔８１のケース８の外側から内側に向けて徐々に挿入孔８１の内径が小さくなっている。図５～図７Ｂでは、挿入口１１の図示を省略しているが、このようなケース８を備える端子装置１においては、ケース８の挿入孔８１が挿入口１１に相当する。 An insertion hole 81 that penetrates the bottom plate of the case 8 in the Y-axis direction is formed at a position corresponding to the insertion port 11 in the case 8. Two insertion holes 81 have a circular opening shape and are formed so as to correspond to the two electric wires 100. The inner diameter of the insertion hole 81 is not constant, and the inner diameter of the insertion hole 81 gradually decreases from the outer side to the inner side of the case 8 of the insertion hole 81 in a part in the Y-axis direction so as to attract the electric wire 100. . 5 to 7B, the insertion port 11 is not shown, but in the terminal device 1 including such a case 8, the insertion hole 81 of the case 8 corresponds to the insertion port 11.
　また、ケース８のうちスリット２３に対応する位置には、ケース８の側壁をＸ方向に貫通する操作窓８２が形成されている。操作窓８２は、後述する解除部材９のガイド突起９３を通すための孔である。操作窓８２の内側面のうち、Ｚ軸方向に対向する一対の内側面には、解除部材９を保持するための一対の軸受部８３が形成されている。一対の軸受部８３には、後述する解除部材９の軸部９１が挿入される。 Further, an operation window 82 penetrating the side wall of the case 8 in the X direction is formed at a position corresponding to the slit 23 in the case 8. The operation window 82 is a hole through which a guide projection 93 of the release member 9 described later is passed. A pair of bearing portions 83 for holding the release member 9 is formed on a pair of inner surfaces facing the Z-axis direction among the inner surfaces of the operation window 82. A shaft portion 91 of the release member 9 described later is inserted into the pair of bearing portions 83.
　解除部材９は、鎖錠部４による電線１００の移動の規制、つまり鎖錠部４による電線１００の抜け止めを解除するための部材である。解除部材９は、電気絶縁性を有する材料、例えば合成樹脂にて構成されている。解除部材９は、端子部２に対して、通常位置と解除位置との間で相対的に移動可能に構成される。通常位置とは、解除部材９が鎖錠部４による電線１００の抜け止めを解除しない状態にあるときの解除部材９の位置をいう。一方、解除位置とは、解除部材９が鎖錠部４による電線１００の抜け止めを解除する状態にあるときの解除部材９の位置をいう。つまり、解除部材９は、通常位置から解除位置に移動するとき、鎖錠部４に対して第２部位２２から離れる向きの力を作用させ、鎖錠部４による電線１００の移動の規制（抜け止め）を解除する。図６Ａ～図７Ｂでは、解除部材９が通常位置にある状態を表している。 The release member 9 is a member for releasing the restriction of the movement of the electric wire 100 by the locking part 4, that is, the prevention of the electric wire 100 from coming off by the locking part 4. The release member 9 is made of an electrically insulating material such as a synthetic resin. The release member 9 is configured to be movable relative to the terminal portion 2 between a normal position and a release position. The normal position refers to the position of the release member 9 when the release member 9 is in a state in which the locking of the electric wire 100 by the locking part 4 is not released. On the other hand, the release position refers to the position of the release member 9 when the release member 9 is in a state in which the locking of the electric wire 100 by the locking part 4 is released. That is, when the release member 9 moves from the normal position to the release position, a force in a direction away from the second portion 22 is applied to the lock portion 4, and the movement of the electric wire 100 by the lock portion 4 is regulated (disengaged). Release (stop). 6A to 7B show a state in which the release member 9 is in the normal position.
　具体的には、解除部材９は、軸部９１と、操作部９２と、ガイド突起９３とを有している。 Specifically, the release member 9 has a shaft portion 91, an operation portion 92, and a guide protrusion 93.
　軸部９１は、Ｚ軸方向に沿った円柱状に形成されている。解除部材９は、軸部９１のＺ軸方向の両端部が一対の軸受部８３に挿入されることによって、ケース８に対して軸部９１を中心として回転可能な状態で、ケース８に保持される。これにより、解除部材９は、軸部９１を中心として、通常位置と解除位置との間で回転（移動）可能となる。ここでは、軸受部８３は、図６Ａ及び図６Ｂに示すように、Ｘ軸の負の向きに開放されている。ただし、端子ブロック１２がケース８に収納された状態では、端子ブロック１２の連結部３０によってＸ軸の負の向きへの軸部９１の移動が規制され、軸受部８３からの軸部９１の脱落が防止される。また、解除部材９のうち、端子室８０の底面に対向する面は、軸部９１を中心とする略円弧状に形成されていることが好ましい。これにより、解除部材９が軸部９１を中心に解除部材９が回転したときに、解除部材９から端子室８０の底面までの距離が大きく変動せず、解除部材９とケース８との干渉を回避できる。 The shaft portion 91 is formed in a cylindrical shape along the Z-axis direction. The release member 9 is held by the case 8 in a state of being rotatable about the shaft portion 91 with respect to the case 8 by inserting both ends of the shaft portion 91 in the Z-axis direction into the pair of bearing portions 83. The As a result, the release member 9 can be rotated (moved) between the normal position and the release position with the shaft portion 91 as the center. Here, as shown in FIGS. 6A and 6B, the bearing portion 83 is opened in the negative direction of the X axis. However, in a state where the terminal block 12 is housed in the case 8, the movement of the shaft portion 91 in the negative direction of the X axis is restricted by the connecting portion 30 of the terminal block 12, and the shaft portion 91 is dropped from the bearing portion 83. Is prevented. In addition, the surface of the release member 9 that faces the bottom surface of the terminal chamber 80 is preferably formed in a substantially arc shape with the shaft portion 91 as the center. Thereby, when the release member 9 rotates around the shaft portion 91, the distance from the release member 9 to the bottom surface of the terminal chamber 80 does not vary greatly, and the interference between the release member 9 and the case 8 is prevented. Can be avoided.
　操作部９２は、解除部材９を通常位置から解除位置に移動させる際に操作される部分である。解除部材９は、少なくとも操作部９２の一部がケース８から露出するように、ケース８に保持されている。また、操作部９２は、Ｚ軸方向の寸法がケース８の操作窓８２の幅よりも大きく設定されている。したがって、操作部９２は、解除部材９の操作時に、ケース８における操作窓８２の周辺部分に接触することにより、解除部材９の可動範囲を規制するストッパとしても機能する。 The operation unit 92 is a part that is operated when the release member 9 is moved from the normal position to the release position. The release member 9 is held by the case 8 so that at least a part of the operation portion 92 is exposed from the case 8. Further, the operation unit 92 is set such that the dimension in the Z-axis direction is larger than the width of the operation window 82 of the case 8. Therefore, the operation portion 92 also functions as a stopper that restricts the movable range of the release member 9 by contacting the peripheral portion of the operation window 82 in the case 8 when the release member 9 is operated.
　ガイド突起９３は、電線１００の移動方向をＹ軸方向に規制するためのガイド部の少なくとも一部を構成する。ガイド部は、端子部２の一表面２０から突出し、電線１００に対してＺ軸方向の両側に位置する部材である。ガイド部については、「（２．７）ガイド部」の欄で詳しく説明する。解除部材９は、少なくともガイド突起９３の一部が、ケース８の操作窓８２及び端子部２のスリット２３を通して、収容空間５０に挿入されるように、ケース８に保持されている。 The guide protrusion 93 constitutes at least a part of a guide portion for restricting the moving direction of the electric wire 100 in the Y-axis direction. The guide portion is a member that protrudes from one surface 20 of the terminal portion 2 and is located on both sides in the Z-axis direction with respect to the electric wire 100. The guide portion will be described in detail in the column “(2.7) Guide portion”. The release member 9 is held in the case 8 so that at least a part of the guide protrusion 93 is inserted into the accommodation space 50 through the operation window 82 of the case 8 and the slit 23 of the terminal portion 2.
　ガイド突起９３は、Ｙ軸方向において鎖錠部４の両側に位置する第１突片９３１と第２突片９３２とを有している。第１突片９３１は、Ｙ軸方向において、鎖錠部４に対して挿入口１１（挿入孔８１）側に位置する。第２突片９３２は、Ｙ軸方向において、鎖錠部４に対して挿入口１１（挿入孔８１）とは反対側に位置する。つまり、第１突片９３１と第２突片９３２とは、収容空間５０内において、鎖錠部４を挟むような位置関係にある。本実施形態では、第１突片９３１は台形板状であって、第２突片９３２は矩形板状である。 The guide projection 93 has a first projecting piece 931 and a second projecting piece 932 located on both sides of the locking part 4 in the Y-axis direction. The first protrusion 931 is located on the insertion port 11 (insertion hole 81) side with respect to the lock portion 4 in the Y-axis direction. The second projecting piece 932 is positioned on the opposite side of the insertion port 11 (insertion hole 81) with respect to the lock portion 4 in the Y-axis direction. That is, the first projecting piece 931 and the second projecting piece 932 are in a positional relationship such that the locking part 4 is sandwiched in the accommodation space 50. In the present embodiment, the first protruding piece 931 has a trapezoidal plate shape, and the second protruding piece 932 has a rectangular plate shape.
　第１突片９３１は、作用部９４及び回避部９５を含んでいる。台形板状の第１突片９３１においては、台形の上底（平行する２辺のうち短い方の辺）と台形の脚（不平行な２辺のうち一方の辺）との間の角部が作用部９４に相当し、台形の上底が回避部９５に相当する。 The first projecting piece 931 includes an action part 94 and an avoidance part 95. In the trapezoidal plate-like first projecting piece 931, the corner between the upper base of the trapezoid (the shorter side of the two parallel sides) and the trapezoidal leg (one of the two non-parallel sides) Corresponds to the action portion 94, and the upper base of the trapezoid corresponds to the avoidance portion 95.
　作用部９４は、解除部材９が通常位置から解除位置に移動する際に、鎖錠部４に第２部位２２から離れる向きの力を作用させる部分である。つまり、解除部材９は、通常位置から解除位置に移動するときに、作用部９４にて、鎖錠部４に接触して鎖錠部４に対して端子部２の一表面２０から離れる向きの力を作用させる。作用部９４は、鎖錠部４のうち先端縁４１寄りの部位に対向する。これにより、解除部材９は、通常位置から解除位置に移動するときに、作用部９４にて鎖錠部４の先端縁４１付近に接触する。そのため、解除部材９は、鎖錠部４に対し、ばね部４２を支点として比較的大きなモーメントを作用させることができ、結果的に、比較的小さな力で鎖錠部４を変位させることができる。 The action portion 94 is a portion that applies a force in a direction away from the second portion 22 to the lock portion 4 when the release member 9 moves from the normal position to the release position. That is, when the release member 9 moves from the normal position to the release position, the action portion 94 is in contact with the lock portion 4 and is away from the one surface 20 of the terminal portion 2 with respect to the lock portion 4. Apply force. The action portion 94 faces a portion of the lock portion 4 near the tip edge 41. Thereby, when the release member 9 moves from the normal position to the release position, it contacts the vicinity of the front end edge 41 of the lock part 4 at the action part 94. Therefore, the release member 9 can cause a relatively large moment to act on the lock portion 4 with the spring portion 42 as a fulcrum, and as a result, the lock portion 4 can be displaced with a relatively small force. .
　回避部９５は、解除部材９が通常位置から解除位置に移動するときに作用部９４以外での鎖錠部４との接触を回避するための空隙ＳＰ１（図７Ｂ参照）を、鎖錠部４との間に形成する。そのため、回避部９５が無く第１突片９３１が空隙ＳＰ１を埋めるような形状（三角形板状）である場合に比べて、小さな力で鎖錠部４を変位させることができる。すなわち、回避部９５によって、第１突片９３１と鎖錠部４との間には空隙ＳＰ１が形成されるので、解除部材９は、通常位置から解除位置に移動するときに、作用部９４以外での鎖錠部４との接触を回避できる。そのため、解除部材９は、通常位置から解除位置に移動する際に、作用部９４にて鎖錠部４の先端縁４１付近に接触し続けることができ、鎖錠部４に対し、ばね部４２を支点として比較的大きなモーメントを作用させることができる。 The avoiding portion 95 provides a clearance SP1 (see FIG. 7B) for avoiding contact with the lock portion 4 other than the action portion 94 when the release member 9 moves from the normal position to the release position. Form between. Therefore, the locking part 4 can be displaced with a small force compared to the case where there is no avoiding part 95 and the first protruding piece 931 has a shape (triangular plate shape) that fills the gap SP1. That is, since the clearance SP1 is formed between the first projecting piece 931 and the locking part 4 by the avoiding part 95, the release member 9 is not the action part 94 when moving from the normal position to the release position. Contact with the locked portion 4 can be avoided. Therefore, when the release member 9 moves from the normal position to the release position, it can continue to contact the vicinity of the distal end edge 41 of the lock portion 4 by the action portion 94, and the spring portion 42 with respect to the lock portion 4. A relatively large moment can be applied to the fulcrum.
　上記構成により、端子装置１と電線１００との接続を解除する場合、作業者は、解除部材９を操作することで、鎖錠部４による電線１００の抜け止めを解除して、挿入口１１から電線１００を抜去することができる。すなわち、解除部材９が通常位置にある状態から、作業者が操作部９２を図７Ｂに矢印Ａ１で示す向きに押すと、解除部材９が軸部９１を中心にして解除位置に移動する。このとき、作用部９４は、図７Ｂに矢印Ａ２で示す向きに移動し、鎖錠部４の先端縁４１に対して第２部位２２から離れる向きの力を作用させる。先端縁４１が第２部位２２から離れる向きに移動すると、鎖錠部４が電線１００から離れて、鎖錠部４による電線１００の移動の規制（抜け止め）が解除される。 With the above configuration, when the connection between the terminal device 1 and the electric wire 100 is released, the operator operates the release member 9 to release the retaining of the electric wire 100 by the locking portion 4 and from the insertion port 11. The electric wire 100 can be removed. That is, when the operator pushes the operation unit 92 in the direction indicated by the arrow A1 in FIG. 7B from the state where the release member 9 is in the normal position, the release member 9 moves to the release position about the shaft portion 91. At this time, the action portion 94 moves in the direction indicated by the arrow A2 in FIG. 7B and applies a force in a direction away from the second portion 22 to the distal end edge 41 of the lock portion 4. When the distal end edge 41 moves away from the second portion 22, the locking portion 4 is separated from the electric wire 100, and the restriction (prevention of movement) of the electric wire 100 by the locking portion 4 is released.
　また、本実施形態では、２つの鎖錠部４に対して、１つの解除部材９から同時に力が作用するように構成されている。つまり、解除部材９のガイド突起９３は、Ｚ軸方向において２つの鎖錠部４に跨る位置に配置されている。これにより、解除部材９が通常位置から解除位置に移動すると、２つの鎖錠部４に対して、第２部位２２から離れる向きの力が同時に作用し、２つの鎖錠部４について同時に抜け止めが解除される。 Moreover, in this embodiment, it is comprised so that force may act simultaneously on the two lock | rock parts 4 from the one cancellation | release member 9. FIG. That is, the guide protrusion 93 of the release member 9 is disposed at a position straddling the two lock portions 4 in the Z-axis direction. As a result, when the release member 9 moves from the normal position to the release position, a force in a direction away from the second portion 22 acts simultaneously on the two lock portions 4, and the two lock portions 4 are simultaneously prevented from coming off. Is released.
　ところで、上述したような端子装置１は、以下の手順で組み立て可能である。端子ブロック１２、ばねブロック１３及び解除部材９は、ケース８に対して、ばねブロック１３、端子ブロック１２、解除部材９の順に取り付けられる。具体的には、まず、ばねブロック１３が、ケース８の端子室８０に収納される。次に、端子ブロック１２が、ケース８の端子室８０に収納される。このとき、先に端子室８０に収納されているばねブロック１３は、端子ブロック１２のうちＹ軸方向における挿入口１１側の端面に形成された開口部１２１から、収容空間５０に導入されることになる。つまり、端子ブロック１２の開口部１２１を通して、筒状体１２０の内側の収容空間５０に、ばねブロック１３が導入されるようにして、端子ブロック１２とばねブロック１３とが組み合わされる。次に、解除部材９が、ケース８の軸受部８３に軸部９１の両端部を挿入するように、ケース８に取り付けられる。 By the way, the terminal device 1 as described above can be assembled by the following procedure. The terminal block 12, the spring block 13, and the release member 9 are attached to the case 8 in the order of the spring block 13, the terminal block 12, and the release member 9. Specifically, first, the spring block 13 is accommodated in the terminal chamber 80 of the case 8. Next, the terminal block 12 is accommodated in the terminal chamber 80 of the case 8. At this time, the spring block 13 previously accommodated in the terminal chamber 80 is introduced into the accommodating space 50 from the opening 121 formed on the end face on the insertion port 11 side in the Y-axis direction of the terminal block 12. become. That is, the terminal block 12 and the spring block 13 are combined so that the spring block 13 is introduced into the accommodation space 50 inside the cylindrical body 120 through the opening 121 of the terminal block 12. Next, the release member 9 is attached to the case 8 so that both end portions of the shaft portion 91 are inserted into the bearing portion 83 of the case 8.
　上述したような組み立て手順によれば、端子装置１の組み立てを自動化することも可能である。要するに、上記組み立て手順では、ケース８に対して、端子室８０の開口面側（Ｙ軸の正の側）から、ばねブロック１３、端子ブロック１２、解除部材９を順に落下させるだけで、端子装置１の組み立てが可能である。したがって、端子装置１の組み立ては、自動組立機にて容易に実現可能である。 According to the assembly procedure as described above, the assembly of the terminal device 1 can be automated. In short, in the above assembly procedure, the terminal device is simply dropped from the opening surface side (the positive side of the Y axis) of the terminal chamber 80 with respect to the case 8 in this order, by dropping the spring block 13, the terminal block 12, and the release member 9 in order. 1 assembly is possible. Therefore, the assembly of the terminal device 1 can be easily realized by an automatic assembly machine.
　（２．７）ガイド部
　次に、電線１００の移動方向をＹ軸方向に規制するためのガイド部について、図８Ａ及び図８Ｂを参照して説明する。図８Ａ及び図８Ｂは、図７ＡのＺ２－Ｚ２線断面図であって、解除部材９を想像線（２点鎖線）で示している。また、図８Ａ及び図８Ｂでは、後述する位置Ｐ１～Ｐ３を１点鎖線で示しているが、位置Ｐ１～Ｐ３は説明のために表記しているに過ぎず、実体を伴わない。 (2.7) Guide Part Next, a guide part for restricting the moving direction of the electric wire 100 in the Y-axis direction will be described with reference to FIGS. 8A and 8B. 8A and 8B are cross-sectional views taken along the line Z2-Z2 of FIG. 7A, and the release member 9 is indicated by an imaginary line (two-dot chain line). 8A and 8B, positions P1 to P3, which will be described later, are indicated by alternate long and short dash lines, but the positions P1 to P3 are merely shown for explanation, and do not involve an entity.
　ガイド部は、端子部２の一表面２０から突出し、電線１００に対してＺ軸方向の両側に位置することにより、電線１００の移動方向をＹ軸方向に規制する。本実施形態では、ガイド部は、側壁部６及びガイド突起９３にて構成されている。言い換えれば、側壁部６及びガイド突起９３は、それぞれガイド部としての機能を備えている。つまり、挿入口１１（挿入孔８１）から挿入される電線１００は、Ｚ軸方向の両側に位置する側壁部６及びガイド突起９３に接触することにより、Ｚ軸方向への移動が規制される。Ｘ軸方向への電線１００の移動は、鎖錠部４及び押付部３と、端子部２との間に電線１００が挟まれることによって規制されている。 The guide portion protrudes from one surface 20 of the terminal portion 2 and is positioned on both sides in the Z-axis direction with respect to the electric wire 100, thereby restricting the moving direction of the electric wire 100 in the Y-axis direction. In the present embodiment, the guide portion is constituted by the side wall portion 6 and the guide protrusion 93. In other words, the side wall portion 6 and the guide protrusion 93 each have a function as a guide portion. That is, the electric wire 100 inserted from the insertion port 11 (insertion hole 81) is restricted from moving in the Z-axis direction by contacting the side wall portions 6 and the guide protrusions 93 located on both sides in the Z-axis direction. The movement of the electric wire 100 in the X-axis direction is restricted by the electric wire 100 being sandwiched between the locking portion 4 and the pressing portion 3 and the terminal portion 2.
　本実施形態では、端子装置１は２極型の端子装置であるので、ガイド部は、２本の電線１００に対応するように構成されている。具体的には、収容空間５０のＺ軸方向の両側には２つの側壁部６が位置し、これら２つの側壁部６の中間位置にガイド突起９３が位置している。そのため、収容空間５０は、Ｚ軸方向においてガイド突起９３にて２つの領域に区分され（図７Ａ参照）、これら２つの領域が２本の電線１００にそれぞれ対応する。そして、一方の電線１００については、一方の側壁部６及びガイド突起９３がガイド部として機能し、他方の電線１００については、他方の側壁部６及びガイド突起９３がガイド部として機能する。 In the present embodiment, since the terminal device 1 is a two-pole type terminal device, the guide portion is configured to correspond to the two electric wires 100. Specifically, the two side wall portions 6 are located on both sides in the Z-axis direction of the accommodation space 50, and the guide protrusion 93 is located at an intermediate position between the two side wall portions 6. Therefore, the accommodation space 50 is divided into two regions by the guide protrusion 93 in the Z-axis direction (see FIG. 7A), and these two regions correspond to the two electric wires 100, respectively. And about one electric wire 100, one side wall part 6 and the guide protrusion 93 function as a guide part, and about the other electric wire 100, the other side wall part 6 and the guide protrusion 93 function as a guide part.
　とくに、電線１００が複数本の導線からなる心線を有する撚り線である場合には、ガイド部によって電線１００の移動方向が規制されることにより、心線を構成する複数本の導線がばらばらになりにくい。すなわち、挿入口１１（挿入孔８１）から電線１００が挿入されると、電線１００の先端は、まず、鎖錠部４と端子部２との間に導入され、次に、押付部３と端子部２との間に導入される。このとき、図８Ａ及び図８Ｂに示すように、電線１００は、まず位置Ｐ１にて鎖錠部４と接触し、次に位置Ｐ２にて、鎖錠部４の先端縁４１と端子部２との間に挟まれ、その後、位置Ｐ３にて、押付部３と端子部２との間に挟まれることになる。そのため、位置Ｐ１～Ｐ３の各々において、電線１００の先端には、鎖錠部４又は押付部３から反力が作用することになり、心線を構成する複数本の導線がばらばらになりやすい。 In particular, when the electric wire 100 is a stranded wire having a core wire composed of a plurality of conductor wires, the guide wire restricts the moving direction of the electric wire 100 so that the plurality of conductor wires constituting the core wire are dispersed. Hard to become. That is, when the electric wire 100 is inserted from the insertion port 11 (insertion hole 81), the tip of the electric wire 100 is first introduced between the locking portion 4 and the terminal portion 2, and then the pressing portion 3 and the terminal. It is introduced between the two parts. At this time, as shown in FIG. 8A and FIG. 8B, the electric wire 100 first contacts the locking part 4 at the position P1, and then at the position P2, the leading edge 41 and the terminal part 2 of the locking part 4 After that, it is sandwiched between the pressing portion 3 and the terminal portion 2 at the position P3. Therefore, in each of the positions P1 to P3, a reaction force acts on the tip of the electric wire 100 from the locking portion 4 or the pressing portion 3, and the plurality of conductive wires constituting the core wire are likely to be separated.
　ここで、ガイド突起９３は、Ｙ軸方向において鎖錠部４の両側に位置する第１突片９３１と第２突片９３２とを有しているため、位置Ｐ１については、第１突片９３１でカバーでき、位置Ｐ２，Ｐ３については第２突片９３２でカバーすることが可能である。つまり、位置Ｐ１においては、電線１００のＺ軸方向の両側に第１突片９３１及び側壁部６が位置するため、心線を構成する複数本の導線がばらばらになることが抑制される。位置Ｐ２，Ｐ３においては、電線１００のＺ軸方向の両側に第２突片９３２及び側壁部６が位置するため、心線を構成する複数本の導線がばらばらになることが抑制される。 Here, since the guide protrusion 93 has the 1st protrusion piece 931 and the 2nd protrusion piece 932 which are located in the both sides of the locking part 4 in a Y-axis direction, about the position P1, the 1st protrusion piece 931 is sufficient. The positions P2 and P3 can be covered with the second projecting piece 932. That is, in the position P1, since the 1st protrusion piece 931 and the side wall part 6 are located in the both sides of the Z-axis direction of the electric wire 100, it is suppressed that the several conducting wire which comprises a core wire is separated. At the positions P2 and P3, since the second projecting piece 932 and the side wall portion 6 are located on both sides of the electric wire 100 in the Z-axis direction, it is possible to suppress a plurality of conductors constituting the core wire from being separated.
　（２．８）配線器具
　上述した構成の端子装置１は、例えば図９に示すような配線器具１０に用いられる。図９に例示する配線器具１０は、建物の壁などに取り付けて使用されるスイッチである。この配線器具１０は、直方体状の器具本体１０１と、器具本体１０１に収納された端子装置１とを備えている。図９の例では、器具本体１０１の前面にハンドル１０２が設けられている。この配線器具１０は、ハンドル１０２が押される度に、器具本体１０１内の接点のオン／オフが切り替わるように構成されている。 (2.8) Wiring device The terminal device 1 having the above-described configuration is used in a wiring device 10 as shown in FIG. 9, for example. A wiring device 10 illustrated in FIG. 9 is a switch used by being attached to a wall of a building or the like. The wiring device 10 includes a rectangular parallelepiped device body 101 and a terminal device 1 housed in the device body 101. In the example of FIG. 9, a handle 102 is provided on the front surface of the instrument main body 101. The wiring device 10 is configured such that the contact in the device main body 101 is switched on / off each time the handle 102 is pressed.
　配線器具１０は、上述した構成の端子装置１を４つ備えている。４つの端子装置１は、それぞれ器具本体１０１の後面に挿入孔８１が露出するように、器具本体１０１に収納されている。これにより、配線器具１０においては、器具本体１０１の後面側から電線１００が挿入されることにより、電線１００の接続が可能になる。４つの端子装置１は、Ｚ軸方向に並ぶように２つの端子装置１を１組として、器具本体１０１におけるＸ軸方向の両端部に１組ずつ配置されている。そのため、器具本体１０１の後面には、Ｚ軸方向に４つずつ、Ｘ軸方向に２つずつ並ぶように、計８つの挿入孔８１が形成される。 The wiring device 10 includes four terminal devices 1 configured as described above. The four terminal devices 1 are housed in the instrument body 101 so that the insertion holes 81 are exposed on the rear surface of the instrument body 101, respectively. Thereby, in the wiring device 10, the electric wire 100 can be connected by inserting the electric wire 100 from the rear surface side of the device main body 101. The four terminal devices 1 are arranged at both ends in the X-axis direction of the instrument body 101 as a set of two terminal devices 1 so as to be aligned in the Z-axis direction. Therefore, a total of eight insertion holes 81 are formed on the rear surface of the instrument body 101 so that four are arranged in the Z-axis direction and two in the X-axis direction.
　ところで、器具本体１０１の寸法は、例えば「１個モジュール寸法」のように、各国の規格などによって決められていることが多い。このような器具本体１０１において、Ｚ軸方向に４つもの挿入孔８１を並べようとすると、挿入孔８１間の間隔、つまり端子装置１のＺ軸方向の寸法を小さく抑える必要がある。本実施形態に係る端子装置１は、Ｚ軸方向の寸法を抑えやすい構成であるので、このような配線器具１０に特に適している。 By the way, the dimensions of the instrument body 101 are often determined by the standards of each country, such as “one module dimension”. In such an instrument body 101, when as many as four insertion holes 81 are arranged in the Z-axis direction, it is necessary to keep the distance between the insertion holes 81, that is, the dimension of the terminal device 1 in the Z-axis direction small. The terminal device 1 according to the present embodiment is particularly suitable for such a wiring device 10 because it is configured to easily reduce the dimension in the Z-axis direction.
　ここで、端子装置１のケース８（図５参照）は、器具本体１０１の器体とは別体であってもよいし、器具本体１０１の器体の一部であってもよい。また、解除部材９（図７参照）は、少なくとも操作部９２（図７参照）の一部が器具本体１０１の器体から露出するように、器具本体１０１の器体又はケース８に保持される。 Here, the case 8 (see FIG. 5) of the terminal device 1 may be a separate body from the instrument body 101 or a part of the instrument body 101. Further, the release member 9 (see FIG. 7) is held by the device body or case 8 of the instrument main body 101 so that at least a part of the operation unit 92 (see FIG. 7) is exposed from the instrument body of the instrument main body 101. .
　（３）利点
　以上説明したように、第１の態様に係る端子装置１は、端子部２と、押付部３と、鎖錠部４と、対向部５と、側壁部６と、を備える。押付部３は、端子部２の一表面２０と対向するように配置され、挿入口１１から挿入方向（Ｙ軸方向）に沿って挿入される電線１００を端子部２との間に挟み込む。鎖錠部４は、端子部２の一表面２０と対向するように配置され、電線１００に接触して電線１００の挿入口１１側への移動を規制する。対向部５は、端子部２の一表面２０と対向するように配置され、端子部２との間に押付部３及び鎖錠部４が収まる収容空間５０を形成する。側壁部６は、端子部２と対向部５とを連結する。側壁部６は、端子部２及び対向部５における、幅方向（Ｚ軸方向）の少なくとも一端部同士を連結している。幅方向は、端子部２の一表面２０に平行であって挿入方向に直交する方向である。 (3) Advantages As described above, the terminal device 1 according to the first aspect includes the terminal portion 2, the pressing portion 3, the locking portion 4, the facing portion 5, and the side wall portion 6. The pressing portion 3 is disposed so as to face the one surface 20 of the terminal portion 2, and sandwiches the electric wire 100 inserted along the insertion direction (Y-axis direction) from the insertion port 11 between the terminal portion 2. The locking part 4 is disposed so as to face the one surface 20 of the terminal part 2 and contacts the electric wire 100 to restrict the movement of the electric wire 100 toward the insertion port 11. The facing portion 5 is disposed so as to face the one surface 20 of the terminal portion 2, and forms an accommodating space 50 in which the pressing portion 3 and the locking portion 4 are accommodated between the facing portion 5. The side wall portion 6 connects the terminal portion 2 and the facing portion 5. The side wall portion 6 connects at least one end portions of the terminal portion 2 and the facing portion 5 in the width direction (Z-axis direction). The width direction is a direction parallel to the one surface 20 of the terminal portion 2 and orthogonal to the insertion direction.
　この構成によれば、電線１００は、押付部３と端子部２との間、及び鎖錠部４と端子部２との間の２箇所で保持されるので、挿入方向（Ｙ軸方向）に対して電線１００が傾きにくくなる。そのため、電線１００は、電線１００の硬さによらず端子部２に対して面接触することが可能となり、電線１００と端子部２との接触状態が安定する。したがって、端子装置１では、端子部２に対する電線１００の接触状態が不安定になりにくい、という利点がある。電線１００と端子部２との接触状態が安定すれば、電線１００と端子部２との間の接触抵抗も安定し、接触抵抗が高くなることによる端子部２の温度上昇が抑制される。 According to this structure, since the electric wire 100 is hold | maintained in two places between the pressing part 3 and the terminal part 2, and between the locking part 4 and the terminal part 2, it is in an insertion direction (Y-axis direction). On the other hand, the electric wire 100 becomes difficult to tilt. Therefore, the electric wire 100 can come into surface contact with the terminal portion 2 regardless of the hardness of the electric wire 100, and the contact state between the electric wire 100 and the terminal portion 2 is stabilized. Therefore, in the terminal device 1, there exists an advantage that the contact state of the electric wire 100 with respect to the terminal part 2 does not become unstable easily. If the contact state between the electric wire 100 and the terminal portion 2 is stabilized, the contact resistance between the electric wire 100 and the terminal portion 2 is also stabilized, and the temperature rise of the terminal portion 2 due to the increase in the contact resistance is suppressed.
　さらに、上記構成の端子装置１によれば、側壁部６にて、電線１００の移動方向を挿入方向（Ｙ軸方向）に規制するためのガイド部の少なくとも一部を構成することができる。電線１００の移動方向の規制は、例えば、端子部２の一表面２０に挿入方向に延びるガイド溝を形成することでも実現可能であるが、側壁部６をガイド部として用いることにより、幅方向（Ｚ軸方向）において端子装置１の小型化が可能である。すなわち、端子部２にガイド溝が形成される場合、幅方向において連結部３０と同じ位置にガイド溝を形成することは構造上困難であるため、連結部３０とガイド溝とは幅方向にずれた位置に設けられる。この場合、端子装置１の幅方向の寸法はガイド溝の分だけ大きくなる。これに対して、側壁部６がガイド部の少なくとも一部を兼ねる構成では、端子装置１の幅方向の寸法を小さく抑えることが可能である。 Furthermore, according to the terminal device 1 having the above-described configuration, the side wall portion 6 can constitute at least a part of a guide portion for restricting the moving direction of the electric wire 100 in the insertion direction (Y-axis direction). Restriction of the moving direction of the electric wire 100 can be realized, for example, by forming a guide groove extending in the insertion direction on the one surface 20 of the terminal portion 2, but by using the side wall portion 6 as a guide portion, the width direction ( The terminal device 1 can be downsized in the Z-axis direction). That is, when a guide groove is formed in the terminal portion 2, it is structurally difficult to form the guide groove at the same position as the connecting portion 30 in the width direction, so the connecting portion 30 and the guide groove are displaced in the width direction. It is provided at the position. In this case, the dimension of the terminal device 1 in the width direction is increased by the amount of the guide groove. On the other hand, in the configuration in which the side wall portion 6 also serves as at least a part of the guide portion, the dimension in the width direction of the terminal device 1 can be kept small.
　また、第２の態様に係る端子装置１は、第１の態様において、端子部２と押付部３とを連結する連結部３０を更に備え、連結部３０は、端子部２のうち、挿入方向（Ｙ軸方向）における挿入口１１とは反対側の端部と、押付部３とを連結していることが好ましい。この構成によれば、端子部２との間に電線１００を挟み込むことにより電線１００を端子部２に押し付ける押付部３は、連結部３０によって端子部２に連結されている。言い換えれば、押付部３は端子部２と一部品として扱うことができる。そのため、端子部２と押付部３とが別部品である構成に比べて、端子部２に対する電線１００の押付力にばらつきが生じにくく、結果的に、端子装置１では、端子部２に対する電線１００の接触状態がより安定する。しかも、この構成によれば、挿入口１１から挿入される電線１００と連結部３０との干渉が生じにくく、連結部３０の設計の自由度が高くなる。ただし、この構成は端子装置１に必須の構成ではなく、例えば、連結部３０は省略されてもよい。さらに、例えば、連結部３０は、端子部２のうち、挿入方向における挿入口１１側の端部と、押付部３とを連結していてもよい。又は、連結部３０は、端子部２のうち、Ｚ軸方向における一端部と、押付部３とを連結していてもよい。 Moreover, the terminal device 1 which concerns on a 2nd aspect is further provided with the connection part 30 which connects the terminal part 2 and the pressing part 3 in a 1st aspect, and the connection part 30 is an insertion direction among the terminal parts 2. FIG. It is preferable that the end on the opposite side to the insertion port 11 in the (Y-axis direction) and the pressing portion 3 are connected. According to this configuration, the pressing portion 3 that presses the electric wire 100 against the terminal portion 2 by sandwiching the electric wire 100 with the terminal portion 2 is connected to the terminal portion 2 by the connecting portion 30. In other words, the pressing part 3 can be handled as one part with the terminal part 2. Therefore, compared to a configuration in which the terminal portion 2 and the pressing portion 3 are separate parts, the pressing force of the electric wire 100 against the terminal portion 2 is less likely to vary. As a result, in the terminal device 1, the electric wire 100 against the terminal portion 2 The contact state is more stable. In addition, according to this configuration, interference between the electric wire 100 inserted from the insertion port 11 and the connecting portion 30 hardly occurs, and the degree of freedom in designing the connecting portion 30 is increased. However, this configuration is not essential for the terminal device 1, and for example, the connecting portion 30 may be omitted. Furthermore, for example, the connecting part 30 may connect the end part on the insertion port 11 side in the insertion direction and the pressing part 3 in the terminal part 2. Or the connection part 30 may connect the one end part in the Z-axis direction and the pressing part 3 among the terminal parts 2.
　また、第３の態様に係る端子装置１は、第２の態様において、挿入方向（Ｙ軸方向）において、距離Ｌ１０は、距離Ｌ１１以下であることが好ましい。距離Ｌ１０は、連結部３０における挿入口１１とは反対側の端部から挿入口１１までの距離である。距離Ｌ１１は、対向部５及び側壁部６における挿入口１１とは反対側の端部から挿入口１１までの距離である。この構成によれば、連結部３０が端子部２から挿入口１１とは反対側に突出しながらも、対向部５及び側壁部６で囲まれた領域からはみ出さない。そのため、連結部３０の突出量の分だけ、押付部３が変位する際の支点から押付部３までの距離を大きくして、連結部３０の変形量（撓み量）を小さく抑えながらも、連結部３０が対向部５及び側壁部６で囲まれた堅牢な構造とすることができる。つまり、連結部３０が対向部５及び側壁部６からはみ出さないので、組み立て前において、連結部３０が変形したり、端子ブロック１２同士が絡まったりすることが抑制される。ただし、この構成は端子装置１に必須の構成ではなく、例えば、距離Ｌ１０は距離Ｌ１１より大きくてもよい。 Further, in the terminal device 1 according to the third aspect, in the second aspect, the distance L10 is preferably equal to or less than the distance L11 in the insertion direction (Y-axis direction). The distance L <b> 10 is a distance from the end of the connecting portion 30 on the side opposite to the insertion port 11 to the insertion port 11. The distance L <b> 11 is a distance from the opposite end of the facing portion 5 and the side wall portion 6 to the insertion port 11 to the insertion port 11. According to this configuration, the connecting portion 30 protrudes from the terminal portion 2 to the side opposite to the insertion port 11, but does not protrude from the region surrounded by the facing portion 5 and the side wall portion 6. Therefore, while the distance from the fulcrum when the pressing portion 3 is displaced to the pressing portion 3 is increased by the amount of protrusion of the connecting portion 30, the amount of deformation (the amount of bending) of the connecting portion 30 is suppressed to a small level. A solid structure in which the portion 30 is surrounded by the facing portion 5 and the side wall portion 6 can be obtained. That is, since the connection part 30 does not protrude from the opposing part 5 and the side wall part 6, it is suppressed before the assembly that the connection part 30 deform | transforms or the terminal blocks 12 are entangled. However, this configuration is not an essential configuration for the terminal device 1, and for example, the distance L10 may be larger than the distance L11.
　また、第４の態様に係る端子装置１は、第１～３のいずれかの態様において、端子部２の一表面２０から突出しており、電線１００に対して幅方向（Ｚ軸方向）の両側に位置するガイド部（側壁部６及びガイド突起９３）を更に備えることが好ましい。この構成によれば、一表面２０に沿う平面内での挿入方向（Ｙ軸方向）以外への電線１００の移動が、ガイド部にて規制されることになるので、電線１００の挿入作業の作業性が向上する。とくに、電線１００が複数本の導線からなる心線を有する撚り線である場合には、電線１００がガイド部の間を通ることで、心線を構成する複数本の導線がばらばらになりにくい。ただし、この構成は端子装置１に必須の構成ではなく、ガイド部は省略されてもよい。 Further, in any one of the first to third aspects, the terminal device 1 according to the fourth aspect protrudes from the one surface 20 of the terminal portion 2 and is opposite to the electric wire 100 in the width direction (Z-axis direction). It is preferable to further include a guide portion (the side wall portion 6 and the guide protrusion 93) located in the position. According to this configuration, since the movement of the electric wire 100 in a plane along the one surface 20 other than the insertion direction (Y-axis direction) is restricted by the guide portion, the operation of inserting the electric wire 100 is performed. Improves. In particular, when the electric wire 100 is a stranded wire having a core made of a plurality of conductors, the plurality of conductors constituting the core are less likely to be separated by passing the wire 100 between the guide portions. However, this configuration is not essential for the terminal device 1 and the guide portion may be omitted.
　また、第５の態様に係る端子装置１は、第１～３のいずれかの態様において、端子部２に対し、通常位置と解除位置との間で相対的に移動可能な解除部材９を更に備えることが好ましい。解除部材９は、通常位置から解除位置に移動するとき、鎖錠部４に対して端子部２の一表面２０から離れる向きの力を作用させ、鎖錠部４による電線１００の移動の規制を解除することが好ましい。この構成によれば、解除部材９の操作によって、鎖錠部４による電線１００の移動の規制を解除した状態で、容易に電線１００の抜去が可能となる。ただし、この構成は端子装置１に必須の構成ではなく、例えば、解除部材９は省略されてもよい。 The terminal device 1 according to the fifth aspect further includes a release member 9 that is relatively movable with respect to the terminal portion 2 between the normal position and the release position in any one of the first to third aspects. It is preferable to provide. When the release member 9 moves from the normal position to the release position, the release member 9 applies a force in a direction away from the one surface 20 of the terminal portion 2 to the lock portion 4 to restrict the movement of the electric wire 100 by the lock portion 4. It is preferable to cancel. According to this configuration, the operation of the release member 9 allows the wire 100 to be easily removed in a state where the restriction of the movement of the wire 100 by the lock portion 4 is released. However, this configuration is not an essential configuration for the terminal device 1. For example, the release member 9 may be omitted.
　また、第６の態様に係る端子装置１は、第５の態様において、端子部２の一表面２０から突出しており、電線１００に対して幅方向（Ｚ軸方向）の両側に位置するガイド部（側壁部６及びガイド突起９３）を更に備えることが好ましい。この構成によれば、一表面２０に沿う平面内での挿入方向（Ｙ軸方向）以外への電線１００の移動が、ガイド部にて規制されることになるので、電線１００の挿入作業の作業性が向上する。とくに、電線１００が複数本の導線からなる心線を有する撚り線である場合には、電線１００がガイド部の間を通ることで、心線を構成する複数本の導線がばらばらになりにくい。ただし、この構成は端子装置１に必須の構成ではなく、ガイド部は省略されてもよい。 Moreover, the terminal device 1 according to the sixth aspect projects from the one surface 20 of the terminal part 2 in the fifth aspect, and is a guide part located on both sides in the width direction (Z-axis direction) with respect to the electric wire 100. It is preferable to further include (side wall part 6 and guide protrusion 93). According to this configuration, since the movement of the electric wire 100 in a plane along the one surface 20 other than the insertion direction (Y-axis direction) is restricted by the guide portion, the operation of inserting the electric wire 100 is performed. Improves. In particular, when the electric wire 100 is a stranded wire having a core made of a plurality of conductors, the plurality of conductors constituting the core are less likely to be separated by passing the wire 100 between the guide portions. However, this configuration is not essential for the terminal device 1 and the guide portion may be omitted.

According to this configuration, since the release member 9 is also used as at least a part of the guide part that regulates the moving direction of the electric wire 100, the structure is simplified compared to the case where the guide part is provided separately from the release member 9. And size reduction can be achieved. However, this configuration is not essential for the terminal device 1, and the guide protrusion 93 may be omitted.
　また、第８の態様に係る端子装置１は、第７の態様において、ガイド突起９３は、第１突片９３１と、第２突片９３２と、を有することが好ましい。第１突片９３１は、挿入方向（Ｙ軸方向）において、鎖錠部４に対して挿入口１１側に位置する。第２突片９３２は、挿入方向において、鎖錠部４に対して挿入口１１とは反対側に位置する。この構成によれば、ガイド突起９３は、鎖錠部４に対して挿入口１１側の位置Ｐ１（図８Ａ参照）と、鎖錠部４に対して挿入口１１とは反対側の位置Ｐ２，Ｐ３（図８Ａ参照）との両方において、電線１００の移動方向を規制できる。ただし、この構成は端子装置１に必須の構成ではなく、例えば、第１突片９３１と第２突片９３２との一方が省略されてもよい。 Further, in the terminal device 1 according to the eighth aspect, in the seventh aspect, it is preferable that the guide protrusion 93 includes a first protruding piece 931 and a second protruding piece 932. The first projecting piece 931 is positioned on the insertion port 11 side with respect to the lock portion 4 in the insertion direction (Y-axis direction). The second projecting piece 932 is located on the side opposite to the insertion port 11 with respect to the lock portion 4 in the insertion direction. According to this configuration, the guide protrusion 93 has a position P1 (see FIG. 8A) on the side of the insertion port 11 with respect to the locking part 4, and a position P2, on the opposite side of the insertion part 11 with respect to the locking part 4. The movement direction of the electric wire 100 can be regulated both in P3 (see FIG. 8A). However, this configuration is not an essential configuration for the terminal device 1. For example, one of the first projecting piece 931 and the second projecting piece 932 may be omitted.

When the release member 9 moves from the normal position to the release position, the action portion 94 contacts the lock portion 4 and applies a force in a direction away from the one surface 20 of the terminal portion 2 to the lock portion 4. . According to this configuration, a part of the guide protrusion 93 that regulates the moving direction of the electric wire 100 is also used as the action part 94, so that the structure is simplified compared to the case where the action part 94 is provided separately from the guide protrusion 93. And downsizing can be achieved. However, this configuration is not essential for the terminal device 1, and the action portion 94 may be provided separately from the guide protrusion 93.

Therefore, the release member 9 can displace the lock portion 4 with a relatively small force. However, this configuration is not an essential configuration for the terminal device 1, and the avoidance unit 95 may be omitted.

According to this configuration, since the pressing unit 3 individually applies a pressing force to the plurality of electric wires 100 respectively inserted from the plurality of insertion ports 11, the followability of the pressing unit 3 with respect to the electric wire 100 is improved. The contact state between the electric wire 100 and the terminal portion 2 is stabilized. However, this configuration is not an essential configuration for the terminal device 1, for example, a configuration in which a single pressing unit 3 sandwiches a plurality of electric wires 100 inserted from a plurality of insertion ports 11 between the terminal unit 2. May be.

That is, the terminal device 1 includes only one side wall portion 6, and one end portion in the Z-axis direction of the terminal portion 2 and one end portion in the Z-axis direction of the facing portion 5 are connected by the side wall portion 6. It may be. In this case, the terminal portion 2, the facing portion 5, and the side wall portion 6 are not cylindrical, but are substantially C-shaped when viewed from one side in the Y-axis direction.
