Description

本発明は、電柱に配置される柱上変圧器から配電される一次側電線が接続される一次側端子と、各需要家に向けて配電される複数の二次側電線がそれぞれ接続される複数の二次側端子とを備える引込分岐端子箱の二次側端子における接続構造に関する。   In the present invention, a primary side terminal to which a primary side electric power distributed from a pole transformer arranged on a power pole is connected, and a plurality of secondary side electric wires to be distributed toward each consumer are respectively connected. It is related with the connection structure in the secondary side terminal of a lead-in branch terminal box provided with the secondary side terminal.

従来、図11に示すように、電柱に配電される高圧送電線から複数の需要家に電力供給すべく、高圧送電線から電柱に配電される柱上変圧器100から配電される電源側電線としての一次側電線101(「引下用分岐電線」ともいう)が、引込分岐端子箱1を介して、各需要家に向けて配電される負荷側電線としての複数の二次側電線2,…(「引込線」ともいう)と電気的に接続(通電)される。引込分岐端子箱1は、図12及び図13に示すように、一次側電線101が接続される一次側端子102(図12において一番下の端子)と、複数の二次側電線2,…(図12及び図13において異なる電線サイズの二次側電線2,…を図示している)がそれぞれ接続される複数の二次側端子3,…(図12において上から四つ分の端子)とを備える。   Conventionally, as shown in FIG. 11, as a power supply side electric wire distributed from a pole transformer 100 distributed from a high voltage power transmission line to a power pole to supply power to a plurality of consumers from the high voltage power transmission line distributed to the power pole. Primary-side electric wires 101 (also referred to as “branch wires for pulling-down”) are distributed to each consumer via the lead-in branch terminal box 1 as a plurality of secondary-side electric wires 2,. (Also referred to as “lead-in wire”) is electrically connected (energized). As shown in FIGS. 12 and 13, the lead-in branch terminal box 1 includes a primary side terminal 102 (the lowest terminal in FIG. 12) to which the primary side electric wire 101 is connected, and a plurality of secondary side electric wires 2,. A plurality of secondary-side terminals 3, ... (four terminals from the top in Fig. 12) to which each of the secondary-side electric wires 2, ... having different wire sizes is shown in Figs. With.

そして、複数の二次側端子3がそれぞれ一次側端子102と電気的に接続(通電)可能に構成されているため、一次側端子102に接続される一次側電線101は、複数の二次側端子3,…にそれぞれ接続される二次側電線2,…と電気的に接続可能に構成される。また、少なくとも二次側端子3は、二次側電線2の一端部2aを収容する収容部4と、収容部4との間に配置される二次側電線2の一端部2aを収容部4に向けて押圧して固定する押圧部5とで構成される。したがって、二次側端子3は、二次側電線2の一端部2a、即ち、被覆(絶縁部)を剥がして剥き出しとなった導電体(導電部)が直接接続するのに適している。なお、一次側端子102についても、略同一の構成としている。   And since the some secondary side terminal 3 is each comprised so that electrical connection (energization) with the primary side terminal 102 is possible, the primary side electric wire 101 connected to the primary side terminal 102 is several secondary side. It is comprised so that electrical connection is possible with the secondary side electric wires 2, ... connected to the terminals 3, ..., respectively. In addition, at least the secondary terminal 3 includes the accommodating portion 4 that accommodates the one end portion 2 a of the secondary side electric wire 2 and the one end portion 2 a of the secondary side electric wire 2 that is disposed between the accommodating portion 4 and the accommodating portion 4. It is comprised with the press part 5 pressed and fixed toward. Therefore, the secondary terminal 3 is suitable for the direct connection of the one end 2a of the secondary electric wire 2, that is, the conductor (conductive part) exposed by peeling off the coating (insulating part). The primary side terminal 102 has substantially the same configuration.

しかしながら、二次側端子3は、複数の二次側電線2,…、特に、電線サイズが異なる複数の二次側電線2,…が直接接続するのに不適である。例えば、一つの二次側端子3(図12において上から三番目の二次側端子3)が、電線サイズが異なる二つの二次側電線2,2と直接接続する場合、図13に示すように、電線サイズが大きい方の二次側電線2の一端部2aが、収容部4及び押圧部5に対して相対変位しない程度に固定されているのに対して、電線サイズが小さい方の二次側電線2の一端部2aは、収容部4及び押圧部5と内接しているが、確実に固定されないことがある(あるいは、収容部4や押圧部5と内接していないこともある)。   However, the secondary terminal 3 is unsuitable for directly connecting a plurality of secondary-side electric wires 2,..., Particularly a plurality of secondary-side electric wires 2,. For example, when one secondary side terminal 3 (secondary side terminal 3 third from the top in FIG. 12) is directly connected to two secondary side wires 2 and 2 having different wire sizes, as shown in FIG. On the other hand, the one end 2a of the secondary-side electric wire 2 with the larger electric wire size is fixed to such an extent that it is not relatively displaced with respect to the accommodating portion 4 and the pressing portion 5, whereas the one with the smaller electric wire size The one end portion 2a of the secondary electric wire 2 is inscribed in the accommodating portion 4 and the pressing portion 5, but may not be fixed securely (or may not be inscribed in the accommodating portion 4 or the pressing portion 5). .

かかる場合、二次側電線2が風や雨などにより振動すると、電線サイズが小さい方の二次側電線2の一端部2aが、二次側端子3(収容部4及び押圧部5)に対して相対変位(振動、揺動、回動)することにより、二次側電線2の一端部2aや収容部4といった導電体(通電部)同士の接触する部位が変化する(一定に維持できない)。したがって、導電体同士の接触する部位が変化するため、導電体同士の接触不良が発生し、かかる二次側電線2で配電される需要家を停電させてしまうことがある。   In such a case, when the secondary electric wire 2 vibrates due to wind or rain, the one end 2a of the secondary electric wire 2 having a smaller electric wire size is against the secondary terminal 3 (the accommodating portion 4 and the pressing portion 5). As a result of relative displacement (vibration, swinging, rotation), the portion where the conductors (current-carrying portions) such as the one end portion 2a and the accommodating portion 4 of the secondary-side electric wire 2 come into contact changes (cannot be maintained constant). . Therefore, since the site | part which conductors contact changes, the contact failure between conductors generate | occur | produces and the customer who distributes electricity by this secondary side electric wire 2 may make a power failure occur.

よって、本発明は、かかる事情に鑑み、引込分岐端子箱内に設けられる二次側端子が複数の二次側電線と接続するのに、二次側端子と直接接続される導電体が二次側端子に対して相対変位して接触不良を起こすのを防止できる接続構造を提供することを課題とする。   Therefore, in view of such circumstances, the present invention provides that the secondary terminal provided in the lead-in branch terminal box is connected to the plurality of secondary electric wires, but the conductor directly connected to the secondary terminal is the secondary. It is an object of the present invention to provide a connection structure capable of preventing a contact failure caused by relative displacement with respect to a side terminal.

A plurality of secondary-side terminals to be connected, and at least the secondary-side terminal is one end of the secondary-side electric wire disposed between the accommodating portion that accommodates one end of the secondary-side electric wire and the accommodating portion In the connection structure at the secondary terminal of the lead-in branch terminal box constituted by the pressing portion that presses and fixes the housing toward the housing portion, the plurality of wire terminal members are provided with a plurality of conductive wire terminal members.

A plurality of secondary-side terminals to be connected, and at least the secondary-side terminal is one end of the secondary-side electric wire disposed between the accommodating portion that accommodates one end of the secondary-side electric wire and the accommodating portion In the connection structure at the secondary side terminal of the lead-in branch terminal box constituted by the pressing portion that is pressed and fixed toward the housing portion, the wire terminal member having conductivity is provided, and the wire terminal member includes the housing portion. In order to prevent relative displacement with respect to the secondary side terminal, it is fixed inscribed in the accommodation portion and the pressing portion, and a plurality of secondary side wires are connected to the wire terminal member. It is characterized by that.

本発明によれば、導電性を有する電線端子部材が収容部に収容され、押圧部に押圧されると、収容部及び押圧部に内接して固定される。それにより、電線端子部材が二次側端子に対して相対変位するのを防止できる。さらに、電線端子部材に複数の二次側電線が接続されるようになっているため、接続されると、複数の二次側電線が電線端子部材を介して一つの二次側端子と接続できる。   According to the present invention, when the electric wire terminal member is accommodated in the accommodating portion and pressed by the pressing portion, it is fixed in contact with the accommodating portion and the pressing portion. Thereby, it can prevent that an electric wire terminal member carries out relative displacement with respect to a secondary side terminal. Furthermore, since a plurality of secondary side wires are connected to the wire terminal member, when connected, a plurality of secondary side wires can be connected to one secondary side terminal via the wire terminal member. .

本発明にかかる接続構造は、電柱に配置される柱上変圧器から配電される一次側電線が接続される一次側端子と、各需要家に向けて配電される複数の二次側電線がそれぞれ接続される複数の二次側端子とを備え、少なくとも二次側端子が、二次側電線の一端部を収容する収容部と、収容部との間に配置される二次側電線の一端部を収容部に向けて押圧して固定する押圧部とで構成される引込分岐端子箱の、二次側端子における接続構造において、導電性を有する電線端子部材を備え、二次側端子に直接接続される二次側電線の一端部及び電線端子部材が、重なり合った状態で収容部に収容されると共に、二次側端子に対して相対変位するのを防止すべく、収容部及び押圧部に内接して固定され、さらに、電線端子部材に少なくとも一つの二次側電線が接続されるようになっていることを特徴とする。   In the connection structure according to the present invention, a primary side terminal to which a primary side electric power distributed from a pole transformer arranged on a power pole is connected, and a plurality of secondary side electric wires distributed to each consumer are respectively provided. A plurality of secondary-side terminals to be connected, and at least the secondary-side terminal is one end of the secondary-side electric wire disposed between the accommodating portion that accommodates one end of the secondary-side electric wire and the accommodating portion In the connection structure at the secondary side terminal of the lead-in branch terminal box composed of a pressing part that presses and fixes the terminal toward the housing part, it is provided with a conductive electric wire terminal member and is directly connected to the secondary side terminal One end of the secondary side electric wire and the electric wire terminal member are accommodated in the accommodating portion in an overlapping state, and in the accommodating portion and the pressing portion to prevent relative displacement with respect to the secondary side terminal. In addition, the wire terminal member is fixed in contact with at least one secondary. Wire is characterized in that is adapted to be connected.

本発明によれば、二次側端子に直接接続される二次側電線の一端部及び導電性を有する電線端子部材が、重なり合って収容部に収容されるため、押圧部に押圧されると、収容部及び押圧部に内接して固定される。それにより、二次側端子に直接接続される二次側電線の一端部及び電線端子部材が、二次側端子に対して相対変位するのを防止できる。さらに、電線端子部材に少なくとも一つの二次側電線が接続されるようになっているため、接続されると、複数の二次側電線が直接又は電線端子部材を介して一つの二次側端子と接続できる。   According to the present invention, the one end portion of the secondary-side electric wire directly connected to the secondary-side terminal and the electric wire terminal member having conductivity are overlapped and accommodated in the accommodating portion, so when pressed by the pressing portion, It is fixed inscribed in the housing part and the pressing part. Thereby, it can prevent that the one end part and electric wire terminal member of a secondary side electric wire directly connected to a secondary side terminal displace relatively with respect to a secondary side terminal. Further, since at least one secondary electric wire is connected to the electric wire terminal member, when connected, a plurality of secondary electric wires can be connected directly or via one electric terminal member to one secondary terminal. Can be connected.

本発明にかかる接続構造においては、複数の電線端子部材は、押圧部が押圧する方向に重なり合って配置されてもよい。かかる構成によれば、複数の電線端子部材が重なり合って配置される方向に押圧部で押圧されるため、例えば、電線端子部材、即ち、二次側端子と直接接続される導電体の全てが収容部及び押圧部と内接しない状態でも、全ての導電体が二次側端子に対して相対変位するのを防止できる。   In the connection structure according to the present invention, the plurality of wire terminal members may be arranged so as to overlap in the direction in which the pressing portion presses. According to such a configuration, since the plurality of wire terminal members are pressed by the pressing portion in a direction in which the plurality of wire terminal members are overlapped, for example, all of the conductors directly connected to the wire terminal member, that is, the secondary terminal are accommodated. Even in a state where the contact portion and the pressing portion are not inscribed, all the conductors can be prevented from being displaced relative to the secondary side terminal.

本発明にかかる接続構造においては、複数の電線端子部材は、それぞれが隣接する電線端子部材と嵌合可能な構成を採用してもよい。かかる構成によれば、電線端子部材が隣接して配置される他の電線端子部材と嵌合するため、嵌合される状態で固定されることで、電線端子部材同士が相対変位するのを確実に防止できる。   In the connection structure according to the present invention, the plurality of wire terminal members may adopt a configuration in which each of the wire terminal members can be fitted to the adjacent wire terminal member. According to such a configuration, since the wire terminal member is fitted with another wire terminal member disposed adjacent to the wire terminal member, the wire terminal members are reliably fixed to each other by being fixed in the fitted state.

したがって、引込分岐端子箱内に設けられる二次側端子が複数の二次側電線と接続するのに、一つの二次側端子と接続される複数の二次側電線のうち少なくとも一つが電線端子部材を介して接続されるため、二次側端子と直接接続される導電体が二次側端子に対して相対変位して接触不良を起こすのを防止できるという優れた効果を奏する。   Therefore, when the secondary terminal provided in the lead-in branch terminal box is connected to a plurality of secondary electric wires, at least one of the plurality of secondary electric wires connected to one secondary terminal is an electric wire terminal. Since it is connected via the member, it has an excellent effect that the conductor directly connected to the secondary side terminal can be prevented from being displaced relative to the secondary side terminal to cause poor contact.

一対(複数)の電線端子部材11,11は、重なり合った状態で収容部4に収容される。具体的には、一対(複数)の電線端子部材11,11のそれぞれ一部が、重なり合った状態で収容部4に収容される。より具体的には、一対(複数)の電線端子部材11,11は、押圧部5が押圧する方向に重なり合って配置される。また、一対(複数)の電線端子部材11,11は、二次側端子3(収容部4及び押圧部5)に対して相対変位するのを防止すべく、収容部4及び押圧部5に内接して固定される。   The pair (multiple) of wire terminal members 11 and 11 are accommodated in the accommodating portion 4 in an overlapping state. Specifically, a part of each of the pair (plurality) of wire terminal members 11 and 11 is accommodated in the accommodating portion 4 in an overlapping state. More specifically, the pair (plurality) of wire terminal members 11 and 11 are arranged so as to overlap in the direction in which the pressing portion 5 presses. Further, the pair of (a plurality of) wire terminal members 11, 11 are disposed in the housing portion 4 and the pressing portion 5 in order to prevent relative displacement with respect to the secondary terminal 3 (the housing portion 4 and the pressing portion 5). Fixed in contact.

また、一対の電線端子部材11,11は、押圧されると圧縮又は変形可能な導電体(例えば銅等の金属)で形成され、互いに重なり合った状態で、二次側電線2の一端部2aである導電体(外周が絶縁部で被覆されている導電部)と略同様な形状、即ち、略円柱状となるように形成される。即ち、一対の電線端子部材11,11は、略円柱状を複数(二つ)に分割した形状である。具体的には、一対の電線端子部材11,11は、重なり合って配置される部位の断面が略半円形状に形成される。そして、電線端子部材11は、幅寸法が収容部4の幅寸法と略同一又はやや小さく形成される。また、電線端子部材11は、接続電線13を接続すべく、端部に筒部を備え、筒部が接続電線13の他端部である導電体に挿入される状態でかしめ処理(圧縮)されることにより、接続電線13が固定(接続)されている。   In addition, the pair of electric wire terminal members 11 and 11 are formed of a conductor (for example, a metal such as copper) that can be compressed or deformed when pressed, and overlap each other at one end portion 2a of the secondary electric wire 2. It is formed to have substantially the same shape as a certain conductor (conductive portion whose outer periphery is covered with an insulating portion), that is, a substantially cylindrical shape. That is, the pair of electric wire terminal members 11 and 11 has a shape obtained by dividing a substantially cylindrical shape into a plurality (two). Specifically, in the pair of electric wire terminal members 11, 11, the cross section of the portion arranged to overlap is formed in a substantially semicircular shape. The wire terminal member 11 is formed so that the width dimension is substantially the same as or slightly smaller than the width dimension of the accommodating portion 4. In addition, the wire terminal member 11 is provided with a cylindrical portion at the end thereof to connect the connecting wire 13, and is crimped (compressed) in a state where the cylindrical portion is inserted into a conductor that is the other end portion of the connecting wire 13. Thus, the connecting wire 13 is fixed (connected).

接続電線13は、接続部12に接続される全ての二次側電線2,…のサイズに対して対応可能とすべく、接続される二次側電線2の最大サイズ以上としている。例えば、接続される二次側電線2が2.6mm(導電体直径2.6ミリメートル)〜22mm2 (導電体断面積22平方ミリメートル)である場合、接続電線13は、経済的な面を考慮して、二次側電線2の最大サイズである22mm2 としている。 The connection electric wire 13 is set to be equal to or larger than the maximum size of the secondary electric wires 2 to be connected in order to be able to cope with the sizes of all the secondary electric wires 2 connected to the connection portion 12. For example, when the secondary electric wire 2 to be connected is 2.6 mm (conductor diameter 2.6 mm) to 22 mm 2 (conductor cross-sectional area 22 square millimeters), the connection wire 13 takes into consideration an economical aspect. Thus, the maximum size of the secondary electric wire 2 is set to 22 mm 2 .

また、接続部12、即ち、接続電線13の一端部は、絶縁されるべく、接続電線13の一端部の導電体を被覆可能な絶縁体のカバー部材14が取り付けられている。また、カバー部材14は、二次側電線2が接続部12と接続した部位(導電体)を絶縁処理可能に構成される。例えば、カバー部材14は、伸縮可能に構成され、さらに、加熱されることにより縮小すると共に、硬化するように構成される。   In addition, an insulating cover member 14 capable of covering the conductor at one end of the connecting wire 13 is attached to the connecting portion 12, that is, one end of the connecting wire 13 to be insulated. Moreover, the cover member 14 is comprised so that the site | part (conductor) which the secondary side electric wire 2 connected with the connection part 12 can be insulated. For example, the cover member 14 is configured to be stretchable, and further configured to be reduced and cured by being heated.

本実施形態にかかる接続構造の構成は以上の通りであり、次に、本実施形態にかかる接続構造が導電体の接触不良を防止する作用について説明する。   The configuration of the connection structure according to this embodiment is as described above. Next, the operation of the connection structure according to this embodiment to prevent contact failure of a conductor will be described.

まず、一方の分岐電線具6の電線端子部材11を引込分岐端子箱1における一方の側面部の孔から挿入し、他方の分岐電線具6の電線端子部材11を引込分岐端子箱1における他方の側面部の孔から挿入する。そして、溝状に形成される収容部4に、幅寸法が略同一である一対の電線端子部材11,11を嵌め込むようにして収容する。具体的には、押圧部5が押圧する方向に、一対の電線端子部材11,11のそれぞれの一部を積層させて配置させる。   First, the wire terminal member 11 of one branch wire fitting 6 is inserted from the hole of one side surface portion of the lead-in branch terminal box 1, and the wire terminal member 11 of the other branch wire fitting 6 is inserted into the other branch wire terminal box 1. Insert from side hole. And it accommodates in the accommodating part 4 formed in groove shape so that a pair of electric wire terminal members 11 and 11 with the substantially same width dimension may be fitted. Specifically, a part of each of the pair of electric wire terminal members 11 and 11 is laminated and arranged in the pressing direction of the pressing portion 5.

そして、螺子受部材7及び螺子部材8を螺合させ、当接部材9を収容部4側に変位させると、当接部材9が収容部4に収容される電線端子部材11と当接する。さらに、螺子受部材7及び螺子部材8の螺合を続けると、一対の電線端子部材11,11が重なり合って配置される方向に押圧部で押圧される。そして、一対の電線端子部材11,11が、重なり合った状態で収容部4に収容されているため、押圧部5に押圧されると、収容部4及び押圧部5に内接して固定される。   Then, when the screw receiving member 7 and the screw member 8 are screwed together and the contact member 9 is displaced toward the housing portion 4, the contact member 9 contacts the wire terminal member 11 housed in the housing portion 4. Further, when the screw receiving member 7 and the screw member 8 are kept screwed together, the pair of wire terminal members 11 and 11 are pressed by the pressing portion in a direction in which they are arranged to overlap each other. And since the pair of electric wire terminal members 11 and 11 are accommodated in the accommodating part 4 in the overlapping state, when pressed by the pressing part 5, they are inscribed and fixed to the accommodating part 4 and the pressing part 5.

具体的には、一対の電線端子部材11,11が変形可能であるため、一方の電線端子部材11は、他方の電線端子部材11及び収容部4と内接すると共に、収容部4と内接する円弧状の部位が収容部4に対応して接触する部位を拡げる(接触面を形成する)ように変形し、さらに、他方の電線端子部材11は、一方の電線端子部材11及び押圧部5と内接すると共に、押圧部5と内接する円弧状の部位が押圧部5に対応して接触する部位を拡げる(接触面を形成する)ように変形する。したがって、一対の電線端子部材11,11は、二次側端子3(収容部4)内で揺動や摺動や回動といった変位を完全に規制された状態(密着した状態)で固定されるため、二次側端子3(収容部4及び押圧部5)に対して相対変位するのが防止される。   Specifically, since the pair of electric wire terminal members 11 and 11 can be deformed, one electric wire terminal member 11 is inscribed in the other electric wire terminal member 11 and the accommodating portion 4 and is inscribed in the accommodating portion 4. The arcuate portion is deformed so as to expand the portion that contacts the accommodating portion 4 (forms a contact surface), and the other wire terminal member 11 includes the one wire terminal member 11 and the pressing portion 5 inside. The arcuate portion in contact with the pressing portion 5 is deformed so as to expand the portion in contact with the pressing portion 5 (form a contact surface). Accordingly, the pair of electric wire terminal members 11 and 11 are fixed in a state where displacement such as swinging, sliding, and turning is completely regulated (closely contacted) in the secondary terminal 3 (accommodating portion 4). For this reason, relative displacement with respect to the secondary side terminal 3 (the accommodating part 4 and the pressing part 5) is prevented.

そして、分岐電線具6の接続部12を覆うカバー部材14の一部を切断し、接続部12に二次側電線2の一端部2aを接続させる。具体的には、絶縁被覆を剥がした(または、剥がしてある)接続電線13の他端部の導電体と、二次側電線2の一端部2aの導電体とを接続部材(圧縮スリーブ)15で接続する。そして、導電体が剥き出しとなる接続部位にカバー部材14を移動させて被覆し、その後カバー部材14を加熱すると、カバー部材14が収縮及び硬化することで接続部位が絶縁処理される。したがって、収容部4から突出する各電線端子部材11の部分に二次側電線2,2が接続電線13を介して接続されるため、二つ(複数)の二次側電線2,2が一対の電線端子部材11,11を介して一つの二次側端子3と接続できる。   And a part of cover member 14 which covers the connection part 12 of the branch electric wire tool 6 is cut | disconnected, and the one end part 2a of the secondary side electric wire 2 is connected to the connection part 12. FIG. Specifically, the connecting member (compression sleeve) 15 is formed by connecting the conductor at the other end of the connecting wire 13 from which the insulating coating has been peeled off (or stripped) and the conductor at the one end 2a of the secondary-side wire 2. Connect with. Then, when the cover member 14 is moved and covered to the connection portion where the conductor is exposed, and then the cover member 14 is heated, the cover portion 14 contracts and hardens, whereby the connection portion is insulated. Therefore, since the secondary side electric wires 2 and 2 are connected to the portions of the electric wire terminal members 11 protruding from the accommodating portion 4 via the connection electric wires 13, two (plural) secondary side electric wires 2 and 2 are paired. Can be connected to one secondary terminal 3 via the electric wire terminal members 11, 11.

以上より、本実施形態にかかる接続構造は、押圧部5が収容部4との間に配置される一対の電線端子部材11,11を収容部4に向けて押圧して固定するため、複数の二次側電線2,2が、確実に固定される一対の電線端子部材11,11を介して一つの二次側端子3と接続できる。したがって、一つの二次側端子3が複数(二つ)の二次側電線2,2と接続するのに、二次側端子3と直接接続される導電体(導電部)、即ち、一対の電線端子部材11,11が二次側端子3に対して相対変位して接触不良を起こすのを防止できる。   As mentioned above, since the connection structure concerning this embodiment presses and fixes a pair of electric wire terminal members 11 and 11 arrange | positioned between the press parts 5 between the accommodating parts 4, toward the accommodating part 4, a some The secondary side electric wires 2 and 2 can be connected to one secondary side terminal 3 through a pair of electric wire terminal members 11 and 11 which are securely fixed. Therefore, when one secondary terminal 3 is connected to a plurality of (two) secondary wires 2, 2, a conductor (conductive portion) directly connected to the secondary terminal 3, that is, a pair of It is possible to prevent the wire terminal members 11 and 11 from being displaced relative to the secondary terminal 3 and causing poor contact.

また、本実施形態にかかる接続構造は、収容部4に収容される一対の電線端子部材11,11が重なり合って配置される方向に押圧されるため、一方の電線端子部材11は、押圧部4及び他方の電線端子部材11に内接して固定され、他方の電線端子部材11は、一方の電線端子部材11及び押圧部5に内接して固定される。したがって、例えば、収容部4の幅方向(押圧される方向に対して直交する方向)に重なり合った状態で収容させる場合、複数の電線端子部材11,11は、それぞれが収容部4及び押圧部5に内接して固定されるべく、押圧される方向の寸法を略同一にする必要があるのに対して、押圧される方向に重なり合った状態で収容される場合は、押圧される方向の寸法を略同一にする必要がなく、電線端子部材11の形状をフレキシブルに対応することができる。   Moreover, since the connection structure concerning this embodiment is pressed in the direction in which a pair of electric wire terminal members 11 and 11 accommodated in the accommodating part 4 overlap and are arrange | positioned, one electric wire terminal member 11 is the press part 4 And the other wire terminal member 11 is fixed in contact with the one wire terminal member 11 and the pressing portion 5. Therefore, for example, when it accommodates in the state which overlapped in the width direction (direction orthogonal to the direction pressed) of the accommodating part 4, the some electric wire terminal members 11 and 11 are the accommodating part 4 and the press part 5, respectively. In order to be inscribed and fixed, the dimensions in the direction to be pressed need to be substantially the same. It is not necessary to make it substantially the same, and the shape of the wire terminal member 11 can be flexibly handled.

次に、本発明にかかる接続構造における第2の実施形態について、図4〜図6を参酌して説明する。なお、図4〜図6において、図1〜図3の符号と同一の符号を付した部分は、第1実施形態と同一の構成又は要素を表す。   Next, a second embodiment of the connection structure according to the present invention will be described with reference to FIGS. 4 to 6, the parts denoted by the same reference numerals as those in FIGS. 1 to 3 represent the same configurations or elements as those in the first embodiment.

本実施形態にかかる接続構造は、図4〜図6に示すように、第1実施形態にかかる接続構造に対して、分岐電線具20の構成が異なり、その他が略同一である。分岐電線具20は、導電性を有する電線端子部材21を備え、電線端子部材21が、収容部4に収容されると共に、二次側端子3に対して相対変位するのを防止すべく、収容部4及び押圧部5に内接して固定され、さらに、電線端子部材21に二つ(複数)の二次側電線2,2が接続されるようになっている。具体的には、分岐電線具20は、電線端子部材21の一部が、収容部4に収容されると共に、二次側端子3に対して相対変位するのを防止すべく、収容部4及び押圧部5に内接して固定され、さらに、二次側端子3(収容部4)から突出する電線端子部材21の部分に二つ(複数)の二次側電線2,2が接続されるようになっている。   As shown in FIGS. 4 to 6, the connection structure according to the present embodiment is different from the connection structure according to the first embodiment in the configuration of the branch wire device 20, and the others are substantially the same. The branch wire device 20 includes a wire terminal member 21 having conductivity, and the wire terminal member 21 is housed in the housing portion 4 and is housed in order to prevent relative displacement with respect to the secondary terminal 3. It is inscribed and fixed to the portion 4 and the pressing portion 5, and two (plural) secondary-side wires 2, 2 are connected to the wire terminal member 21. Specifically, the branch wire device 20 is configured such that a part of the wire terminal member 21 is housed in the housing portion 4 and is prevented from being relatively displaced with respect to the secondary side terminal 3. Two (plural) secondary-side electric wires 2 and 2 are connected to the portion of the electric-wire terminal member 21 that is inscribed and fixed to the pressing portion 5 and protrudes from the secondary-side terminal 3 (accommodating portion 4). It has become.

より具体的には、分岐電線具20は、長尺に形成され、長手方向の中央部に電線端子部材21と、長手方向の両端部にそれぞれ二次側電線2と接続可能な接続部22,22とが設けられる。さらに具体的には、分岐電線20は、長尺な電線端子部材21と、一端部が接続部22となる一対の接続電線23,23とを備え、一方の接続電線23の他端部が電線端子部材21の一端部と、他方の接続電線23の他端部が電線端子部材21の他端部と接続して構成される。また、分岐電線具20は、幅寸法が収容部4の幅寸法より小さくなるように形成される。   More specifically, the branch electric wire device 20 is formed in a long shape, and is connected to the electric wire terminal member 21 at the longitudinal central portion and the connecting portion 22 that can be connected to the secondary electric wire 2 at both longitudinal ends. 22 are provided. More specifically, the branch wire 20 includes a long wire terminal member 21 and a pair of connection wires 23, 23 having one end serving as a connection portion 22, and the other end of one connection wire 23 is a wire. One end of the terminal member 21 and the other end of the other connecting wire 23 are connected to the other end of the wire terminal member 21. Further, the branch electric wire device 20 is formed so that the width dimension is smaller than the width dimension of the accommodating portion 4.

電線端子部材21は、二次側電線2の一端部2aである導電体(内芯の導電部)と略同様な形状、即ち、略円柱形状であって、幅寸法が収容部4の幅寸法と略同一又はやや小さく形成される。また、接続電線23の径寸法は、電線端子部材21の径寸法より小さく形成される。即ち、分岐電線具20において、電線端子部材21の部位が、幅寸法が最大となるように形成されている。つまり、本実施形態にかかる分岐電線具20は、幅寸法が収容部4の幅寸法より小さくなるべく(電線端子部材21の部位で最大になるべく)、第1実施形態にかかる分岐電線具6のように、カバー部材14が設けられていない。なお、分岐電線具20の幅寸法が収容部4の幅寸法より小さく(電線端子部材21の部位で最大と)なり得る場合は、カバー部材14を設けてもよい。   The wire terminal member 21 has a shape that is substantially the same as the conductor (inner core conductive portion) that is the one end portion 2a of the secondary-side wire 2, that is, a substantially cylindrical shape, and the width dimension is the width dimension of the housing portion 4. And substantially the same or slightly smaller. Further, the diameter of the connecting wire 23 is smaller than the diameter of the wire terminal member 21. That is, in the branch electric wire tool 20, the part of the electric wire terminal member 21 is formed so that the width dimension becomes the maximum. That is, the branch wire device 20 according to the present embodiment is like the branch wire device 6 according to the first embodiment so that the width dimension is smaller than the width dimension of the housing portion 4 (to be maximized at the portion of the wire terminal member 21). Further, the cover member 14 is not provided. In addition, when the width dimension of the branch electric wire tool 20 can be smaller than the width dimension of the accommodating part 4 (it is the maximum in the site | part of the electric wire terminal member 21), you may provide the cover member 14.

本実施形態にかかる接続構造の構成は以上の通りであり、次に、本実施形態にかかる接続構造が導電体の接触不良を防止する作用について説明する。   The configuration of the connection structure according to this embodiment is as described above. Next, the operation of the connection structure according to this embodiment to prevent contact failure of a conductor will be described.

まず、収容部4に電線端子部21が配置されるように、分岐電線具20を引込端子箱1に挿通させる。具体的には、分岐電線具20において幅寸法が最大である電線端子部材21に対して、収容部4の幅寸法の方がやや大きい(略同一である)ため、分岐電線具20の一端部を、引込分岐端子箱1における一方の側面部の孔から挿入し、そして、収容部4内を経由して、さらに、引込分岐端子箱1における他方の側面部の孔から一端部を取り出す。これにより、溝状に形成される収容部4に、幅寸法がやや小さい(略同一である)分岐電線具20の電線端子部材21が嵌め込むようにして収容できる。   First, the branch electric wire device 20 is inserted into the lead-in terminal box 1 so that the electric wire terminal portion 21 is disposed in the accommodating portion 4. Specifically, since the width dimension of the accommodating portion 4 is slightly larger (substantially the same) than the wire terminal member 21 having the largest width dimension in the branch wire fitting 20, one end portion of the branch wire fitting 20 is provided. Is inserted from the hole of one side surface portion of the lead-in branch terminal box 1, and one end portion is further taken out from the hole of the other side surface portion of the lead-in branch terminal box 1 through the accommodating portion 4. Thereby, it can accommodate in the accommodating part 4 formed in groove shape so that the electric wire terminal member 21 of the branch electric wire 20 with a slightly small width dimension (substantially the same) may be fitted.

そして、螺子受部材7及び螺子部材8を螺合させると、収容部4に収容される電線端子部材21の一部が押圧部5に押圧され、収容部4及び押圧部5に内接して固定される。それにより、電線端子部材21が二次側端子3に対して相対変位するのを防止できる。具体的には、電線端子部材21は、押圧部5(当接部材9)及び収容部4と内接する部位が双方の表面形状に対応して、密着するように変形し、収容部4内で揺動や摺動や回動といった変位を完全に規制された状態で固定される。   When the screw receiving member 7 and the screw member 8 are screwed together, a part of the electric wire terminal member 21 accommodated in the accommodating portion 4 is pressed by the pressing portion 5 and fixed in contact with the accommodating portion 4 and the pressing portion 5.

Specifically, the electric wire terminal member 21 is deformed so that the portion inscribed with the pressing portion 5 (contact member 9) and the accommodating portion 4 is in close contact with each other in accordance with both surface shapes, and within the accommodating portion 4 The displacement such as swinging, sliding and turning is fixed in a completely regulated state.

そして、両接続部22,22に電線サイズの異なる二次側電線2,2の一端部2a,2aをそれぞれ接続して、接続部位(導電体)を被覆して絶縁処理すると、二次側端子3から突出する電線端子部材21の部分に二つ(複数)の二次側電線2,2が接続電線22を介して接続される。したがって、二つ(複数)の二次側電線2,2は、電線端子部材21を介して一つの二次側端子3と接続できる。   And when one end part 2a, 2a of the secondary side electric wires 2, 2 with different electric wire sizes is connected to both the connection parts 22, 22, respectively, the connection part (conductor) is covered and insulated, and then the secondary side terminal Two (a plurality of) secondary-side electric wires 2, 2 are connected to a portion of the electric wire terminal member 21 protruding from 3 via a connecting electric wire 22. Therefore, the two (a plurality of) secondary-side electric wires 2 and 2 can be connected to one secondary-side terminal 3 via the electric-wire terminal member 21.

以上より、本実施形態にかかる接続構造は、押圧部5が収容部4との間に配置される電線端子部材21を収容部4側に向けて押圧することにより電線端子部材21を固定するため、複数の二次側電線2,2が確実に固定される電線端子部材21を介して一つの二次側端子3と接続できる。したがって、一つの二次側端子3が複数(二つ)の二次側電線2,2と接続するのに、二次側端子3と直接接続される導電体(導電部)、即ち、一つ電線端子部材21が二次側端子3に対して相対変位して接触不良を起こすのを防止できる。   From the above, the connection structure according to the present embodiment fixes the wire terminal member 21 by pressing the wire terminal member 21 arranged between the pressing portion 5 and the housing portion 4 toward the housing portion 4 side. A plurality of secondary side wires 2 and 2 can be connected to one secondary side terminal 3 via a wire terminal member 21 to which the secondary side wires 2 and 2 are securely fixed. Therefore, when one secondary side terminal 3 is connected to a plurality of (two) secondary side wires 2, 2, a conductor (conductive part) directly connected to the secondary side terminal 3, that is, one It is possible to prevent the electric wire terminal member 21 from being displaced relative to the secondary terminal 3 and causing a contact failure.

In addition, in order to prevent relative displacement with respect to the secondary side terminal 3, it is inscribed and fixed to the accommodating portion 4 and the pressing portion 5, and further protrudes from the secondary side terminal 3 (accommodating portion 4). One (second) secondary electric wire 2 is connected to the part of the member 31.

また、二次側端子3に直接接続される二次側電線2の一端部2a及び電線端子部材31は、押圧部4が押圧する方向に重なり合って配置される。そして、分岐電線具30は、一端部に電線端子部材31が設けられ、他端部に二次側電線2の一端部2aと接続可能な接続部32が設けられる。具体的には、分岐電線具30は、一端部が接続部32となる接続電線33を備え、接続電線33の他端部が電線端子部材31と接続して構成される。   Moreover, the one end part 2a of the secondary side electric wire 2 directly connected to the secondary side terminal 3 and the electric wire terminal member 31 are arranged so as to overlap in the direction in which the pressing part 4 presses. And the branch electric wire device 30 is provided with a wire terminal member 31 at one end, and provided with a connecting portion 32 that can be connected to the one end 2a of the secondary-side electric wire 2 at the other end. Specifically, the branch wire device 30 includes a connection wire 33 having one end portion serving as a connection portion 32, and the other end portion of the connection wire 33 is connected to the wire terminal member 31.

電線端子部材31は、押圧されると圧縮又は変形可能な導電体であって、収容部4に収容される先端部が平板状に形成される。さらに、電線端子部材31は、幅寸法が収容部4の幅寸法と略同一又はやや小さく形成される。また、接続部32、即ち、接続電線33の一端部は、絶縁状態を維持すべく、接続電線33の一端部を被覆可能な絶縁体のカバー部材34が取り付けられる。   The electric wire terminal member 31 is a conductor that can be compressed or deformed when pressed, and the tip end portion accommodated in the accommodating portion 4 is formed in a flat plate shape. Furthermore, the electric wire terminal member 31 is formed so that the width dimension is substantially the same as or slightly smaller than the width dimension of the accommodating portion 4. In addition, an insulating cover member 34 that can cover one end of the connecting wire 33 is attached to the connecting portion 32, that is, one end of the connecting wire 33 to maintain an insulating state.

本実施形態にかかる接続構造の構成は以上の通りであり、次に、本実施形態にかかる接続構造が導電体の接触不良を防止する作用について説明する。   The configuration of the connection structure according to this embodiment is as described above. Next, the operation of the connection structure according to this embodiment to prevent contact failure of a conductor will be described.

まず、溝状に形成される収容部4に、二次側端子3に直接接続される二次側電線2の一端部2a及び収容部4と幅寸法が略同一である分岐電線具の電線端子部材31を嵌め込むようにして収容させる。具体的には、二次側電線2の一端部2a及び電線端子部材31の一部は、収容部内4で押圧部5が押圧する方向に重なり合って配置される。より具体的には、収容部4側に二次側電線2の一端部2aが配置され、押圧部5側に電線端子部材31が配置される。   First, the wire terminal of the branch wire fitting in which the width dimension is substantially the same as the one end part 2a of the secondary side electric wire 2 directly connected to the secondary side terminal 3, and the accommodating part 4 in the accommodating part 4 formed in groove shape. The member 31 is accommodated so as to be fitted. Specifically, one end portion 2a of the secondary side electric wire 2 and a part of the electric wire terminal member 31 are arranged so as to overlap each other in the direction in which the pressing portion 5 presses in the accommodating portion 4. More specifically, the one end 2a of the secondary-side electric wire 2 is arranged on the accommodating portion 4 side, and the electric wire terminal member 31 is arranged on the pressing portion 5 side.

そして、螺子受部材7及び螺子部材8を螺合させ、押圧部5を収容部4側に変位させると、収容部4との間に配置される二次側電線2の一端部2a及び電線端子部材31は、押圧部5が重なり合って配置される方向に押圧することにより、収容部4及び押圧部5に内接して固定されるため、二次側端子3(収容部4及び押圧部5)に対して相対変位するのが防止できる。具体的には、二次側電線2の一端部2a(導電体)及び電線端子部材31は、押圧されると変形可能であるため、二次側電線2の一端部2aは、内接する電線端子部材31及び収容部4に対応して変形し、さらに、電線端子部材31は、内接する二次側電線2の一端部2a及び押圧部5に対応して変形する。   And if the screw receiving member 7 and the screw member 8 are screwed together and the pressing part 5 is displaced to the accommodating part 4 side, the one end part 2a of the secondary side electric wire 2 arranged between the accommodating part 4 and the electric wire terminal Since the member 31 is pressed in a direction in which the pressing portions 5 are arranged so as to overlap each other, the member 31 is inscribed and fixed to the receiving portion 4 and the pressing portion 5, so that the secondary terminal 3 (the receiving portion 4 and the pressing portion 5). It is possible to prevent relative displacement with respect to. Specifically, since the one end 2a (conductor) of the secondary side electric wire 2 and the electric wire terminal member 31 can be deformed when pressed, the one end 2a of the secondary side electric wire 2 is an inscribed electric wire terminal. It deform | transforms corresponding to the member 31 and the accommodating part 4, and also the electric wire terminal member 31 deform | transforms corresponding to the one end part 2a and the press part 5 of the secondary side electric wire 2 which inscribes.

したがって、二次側電線2の一端部2a及び電線端子部材31は、二次側端子3(収容部4)内で揺動や摺動や回動といった変位を完全に規制された状態(密着した状態)で固定される。そして、分岐電線具30の接続部32に他の二次側電線2の一端部2aを接続させると、二次側端子3から突出する電線端子部材31の部分に接続電線32を介して一つの二次側電線2が接続される。したがって、一つの二次側端子3と接続される二つ(複数)の二次側電線のうち一つが電線端子部材31を介して接続される。   Therefore, the one end portion 2a of the secondary side electric wire 2 and the electric wire terminal member 31 are in a state in which displacement such as swinging, sliding, and rotation is completely regulated (in close contact) in the secondary side terminal 3 (accommodating portion 4). Fixed). And when one end 2a of the other secondary side electric wire 2 is connected to the connection portion 32 of the branch wire fitting 30, one portion of the electric wire terminal member 31 protruding from the secondary side terminal 3 is connected via the connection electric wire 32. The secondary side electric wire 2 is connected. Therefore, one of the two (a plurality of) secondary wires connected to one secondary terminal 3 is connected via the wire terminal member 31.

以上より、本実施形態にかかる接続構造は、押圧部5が収容部4との間に配置される二次側電線2の一端部2a及び電線端子部材31を収容部4側に向けて押圧するため、二次側端子3に直接接続される二次側電線2の一端部2aや他の二次側電線2の一端部2aに接続される電線端子部材31といった導電体が確実に固定された状態で、一つの二次側端子3が複数の二次側電線2,2と接続できる。したがって、一つの二次側端子3と接続される二つ(複数)の二次側電線2,2のうち一つが電線端子部材31を介して接続されるため、二次側端子3と直接接続される導電体(二次側端子3に直接接続される二次側電線2の一端部2a及び電線端子部材31)が二次側端子3に対して相対変位して接触不良を起こすのを防止できる   As mentioned above, the connection structure concerning this embodiment presses the one end part 2a of the secondary side electric wire 2 arrange | positioned between the press part 5 and the accommodating part 4, and the electric wire terminal member 31 toward the accommodating part 4 side. Therefore, the conductors such as the one end portion 2a of the secondary side electric wire 2 directly connected to the secondary side terminal 3 and the electric wire terminal member 31 connected to the one end portion 2a of the other secondary side electric wire 2 are securely fixed. In this state, one secondary terminal 3 can be connected to the plurality of secondary electric wires 2 and 2. Therefore, since one of the two (plurality) of secondary wires 2 and 2 connected to one secondary terminal 3 is connected via the wire terminal member 31, it is directly connected to the secondary terminal 3. To prevent contact failure caused by relative displacement of the conductor (one end 2a of the secondary side electric wire 2 directly connected to the secondary side terminal 3 and the electric wire terminal member 31) with respect to the secondary side terminal 3 it can

また、本実施形態にかかる接続構造は、収容部4に収容される二次側電線2の一端部2a及び電線端子部材31が重なり合って配置される方向に押圧されるため、例えば、収容部4に収容される二次側電線2の一端部2aや電線端子部材31といった複数の導電体が、互いに相対変位するのを規制すべく、より確実に固定できる。   Moreover, since the connection structure concerning this embodiment is pressed in the direction where the one end part 2a of the secondary side electric wire 2 accommodated in the accommodating part 4 and the electric wire terminal member 31 overlap and are arrange | positioned, for example, the accommodating part 4 The plurality of conductors such as the one end portion 2a of the secondary electric wire 2 and the electric wire terminal member 31 accommodated in the electric wire can be fixed more reliably so as to restrict relative displacement from each other.

なお、本発明の接続構造は、上記した実施の形態に限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。   Note that the connection structure of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention.

例えば、本発明にかかる接続構造においては、複数の電線端子部材は、それぞれが隣接する電線端子部材と嵌合可能な構成されてもよく、電線端子部材は、隣接する二次側電線の一端部及び隣接する他の電線端子部材の少なくとも何れか一方と嵌合可能に構成されてもよい。かかる構成によれば、電線端子部材は、二次側電線の一端部や他の電線端子部材といった隣接される他の導電体と相対変位するのを確実に規制でき、さらに、導電体同士の接触面積を大きくすることもできる。例えば、図10に示すように、凹凸部が設けられる第1電線端子部材40と、第1電線端子部材40の凹凸部に嵌合可能な凹凸部が設けられる第2電線端子部材41とを備えてもよい。   For example, in the connection structure according to the present invention, each of the plurality of wire terminal members may be configured to be able to be fitted with an adjacent wire terminal member, and the wire terminal member is one end of the adjacent secondary-side wire. And it may be comprised so that fitting with at least any one of the other adjacent electric wire terminal members is possible. According to such a configuration, the wire terminal member can be reliably restricted from relative displacement with other adjacent conductors such as one end of the secondary-side wire and other wire terminal members, and further contact between the conductors The area can also be increased. For example, as shown in FIG. 10, the 1st electric wire terminal member 40 provided with an uneven | corrugated | grooved part and the 2nd electric wire terminal member 41 provided with the uneven | corrugated | grooved part which can be fitted in the uneven | corrugated | grooved part of the 1st electric wire terminal member 40 are provided. May be.

なお、図10に示す一対の電線端子部材40,41は、電線端子部材40,41の長手方向に相対変位するのを規制可能に構成されているが、さらに、電線端子部材の幅方向に相対変位するのを規制可能に構成されていてもよく、また、電線端子部材の長手方向及び幅方向に相対変位するのを規制可能に構成されていてもよい。例えば、第1電線端子部材に凸部を設け、第2電線端子部材に第1電線端子部材の凸部に嵌合可能な孔部を設けることにより、第1電線端子部材及び第2電線端子部材が、前記凸部及び前記孔部が挿脱する方向と直交方向に相対変位するのを規制可能に構成されてもよい。   In addition, although a pair of electric wire terminal members 40 and 41 shown in FIG. 10 are comprised so that regulation of relative displacement to the longitudinal direction of the electric wire terminal members 40 and 41 is possible, it is further relative to the width direction of an electric wire terminal member. The displacement may be configured so as to be able to be regulated, and the relative displacement in the longitudinal direction and the width direction of the wire terminal member may be configured to be regulated. For example, a 1st electric wire terminal member and a 2nd electric wire terminal member are provided by providing a convex part in the 1st electric wire terminal member, and providing the hole part which can be fitted in the convex part of the 1st electric wire terminal member in the 2nd electric wire terminal member. However, the convex portion and the hole portion may be configured to be capable of restricting relative displacement in a direction orthogonal to the insertion / removal direction.

However, in such a case, for example, the conductor accommodated in the accommodating portion 4 such as the electric wire terminal member or the one end portion 2a of the secondary side electric wire 2 has substantially the same width dimension in the direction in which the pressing portion 5 presses, The mutual conductors are accommodated in the accommodating portion 4 in an overlapping state, and are fixed in contact with the accommodating portion 4 and the pressing portion 5 in order to prevent relative displacement with respect to the secondary terminal 3. There is a need.

また、上記実施形態にかかる接続構造においては、収容部4に収容される導電体(二次側電線2の一端部2aや電線端子部材11,21,31)が一つ又は二つの場合を説明したが、かかる場合に限られず、収容部4に収容される導電体が三つ以上の場合でもよい。しかしながら、収容部4に収容される導電体が二次側端子3に対して相対変位するのを規制すべく、収容部4に収容される導電体を一つ又は二つとするのが好ましく、あるいは、収容部4に収容される三つ以上の導電体を互いに嵌合可能に構成するのが好ましい。   Moreover, in the connection structure concerning the said embodiment, the case where the conductor (the one end part 2a of the secondary side electric wire 2 or the electric wire terminal members 11, 21, 31) accommodated in the accommodating part 4 is one or two is demonstrated. However, the present invention is not limited to this case, and there may be three or more conductors accommodated in the accommodating portion 4. However, it is preferable that one or two conductors are accommodated in the accommodating portion 4 in order to restrict relative displacement of the conductor accommodated in the accommodating portion 4 with respect to the secondary terminal 3. It is preferable that three or more conductors accommodated in the accommodating portion 4 are configured to be fitted to each other.
