Description

本発明は、電路を開閉するための開閉器、及び開閉器の製造方法に関する。 TECHNICAL FIELD The present invention relates to a switch for opening and closing an electric circuit, and a method for manufacturing the switch.

従来から電路を開閉するための開閉器が種々提供されている。かかる開閉器には、例えば、図６、及び図７に示すように、一次側の電路と二次側の電路とを接続する回路を収容する箱状の筐体８０と、筐体８０内に収容され、且つ前記回路に含まれるとともに、前記回路を開閉可能に構成される開閉部８１と、該開閉部８１の二次側に接続されるリード線８２と、外部機器に接続される二次側端子部材８３であって、前記リード線８２を介して開閉部８１の二次側に接続される二次側端子部材８３と、を備えたものが知られている。 2. Description of the Related Art Conventionally, various switches for opening and closing an electric circuit have been provided. For example, as shown in FIGS. 6 and 7, such a switch includes a box-shaped housing 80 that houses a circuit that connects the primary-side electric circuit and the secondary-side electric circuit, and a An opening/closing portion 81 that is accommodated and included in the circuit and configured to be able to open/close the circuit, a lead wire 82 connected to the secondary side of the opening/closing portion 81, and a secondary connected to an external device. A side terminal member 83 that is connected to the secondary side of the opening/closing portion 81 via the lead wire 82 is known.

筐体８０は、開閉部８１が設けられる第一分割部８００と、二次側端子部材８３が設けられる第二分割部８０１とを有している。 The housing 80 has a first divided portion 800 provided with an opening/closing portion 81 and a second divided portion 801 provided with a secondary side terminal member 83 .

そして、上記構成の開閉器８１は、図６に示すように、二次側端子部材８３が取り付けられた第二分割部８０１を第一分割部８００から外し、第二分割部８０１と第一分割部８００との間にできた広いスペースＳを通じて作業者が筐体８０内に手を入れて、リード線８２を二次側端子部材８３に接続する作業、そして、図７に示すように、第二分割部８０１を第一分割部８００に組み合わせる作業を順番に行っている。 Then, as shown in FIG. 6, the switch 81 having the above configuration removes the second divided portion 801 to which the secondary side terminal member 83 is attached from the first divided portion 800, and separates the second divided portion 801 from the first divided portion. A worker puts his hand into the housing 80 through the wide space S created between the part 800 and connects the lead wire 82 to the secondary side terminal member 83, and as shown in FIG. The operation of combining the two-part dividing part 801 with the first dividing part 800 is performed in order.

ところで、図６、及び図７に示す従来の開閉器８では、二次側端子部材８３とリード線８２との接続部分である接点部８４が筐体８０内で露出しているため、筐体８０の内壁を接点部８４から離す、すなわち、筐体８０の内壁と接点部８４との距離を大きくとることによって、接点部８４と筐体８０との絶縁性を確保している。そのため、前記開閉器８は、筐体８０が大型になる傾向がある。 By the way, in the conventional switch 8 shown in FIGS. The insulation between the contact portion 84 and the housing 80 is ensured by separating the inner wall of the housing 80 from the contact portion 84 , that is, by increasing the distance between the inner wall of the housing 80 and the contact portion 84 . Therefore, the switch 8 tends to have a large housing 80 .

そこで、本発明は、かかる実情に鑑み、小型化に資する開閉器、及び開閉器の製造方法
の提供を課題とする。 Then, in view of such a situation, this invention makes it a subject to provide the switch which contributes to size reduction, and the manufacturing method of a switch.

and an insulating member disposed between a contact portion configured by connecting the lead wire terminal and the terminal main body portion and an inner surface of the housing adjacent to the contact portion.

上記構成の開閉器によれば、接点部と該接点部に近接する筐体の内面との間に絶縁部材が配置されるため、接点部と前記内面との絶縁性を保ったまま接点部と前記内面との距離（絶縁距離）を小さくすることができる。従って、上記構成の開閉器では、筐体の内面に対する接点部の絶縁性を確保するためのスペースを小さくすることができ、これにより、筐体を小型化できるようになっている。 According to the switch having the above configuration, since the insulating member is arranged between the contact portion and the inner surface of the housing adjacent to the contact portion, the contact portion and the inner surface are kept insulated from each other. The distance (insulation distance) to the inner surface can be reduced. Therefore, in the switch with the above configuration, the space for ensuring insulation of the contact portion with respect to the inner surface of the housing can be reduced, so that the housing can be miniaturized.

また、本発明の開閉器において、
前記リード線用端子は、片状の端子片部を有し、
前記筐体は、前記二次側端子部材が挿し込まれる挿込板部を有し、
前記二次側端子部材は、前記筐体内において前記挿込板部から内側に向かう方向に沿って延出する前記端子本体部を有し、
前記接点部は、前記端子本体部と、前記端子本体部に前記端子片部の片面を重ねた状態で固定された前記リード線用端子とで構成され、
前記絶縁部材は、前記端子片部の前記片面と、前記片面に対向する前記挿込板部の内面との間に配置されている。 Moreover, in the switch of the present invention,

The insulating member is arranged between the one surface of the terminal strip portion and the inner surface of the insertion plate portion facing the one surface.

かかる構成によれば、挿込板部の板面（内面）の向きに端子片部の片面の向きを合わせて配置したリード線用端子との間に絶縁部材を配置することによって、リード線用端子の設置スペースとともに筐体の内面に対する接点部の絶縁性を確保するためのスペースを小さくすることによって、筐体を小型化できるようになっている。 According to such a configuration, by arranging the insulating member between the lead wire terminal arranged so that one surface of the terminal piece portion is aligned with the direction of the plate surface (inner surface) of the insertion plate portion, the lead wire terminal is arranged. By reducing the space for installing the terminals and the space for ensuring the insulation of the contact portion from the inner surface of the housing, the housing can be made smaller.

前記絶縁部材を、前記リード線の線方向でスライド可能となるようにして前記リード線に取り付ける絶縁部材取付工程と、
前記リード線用端子と前記端子本体部とを接続して前記接点部を形成する接点部形成工程と、
前記絶縁部材を、前記スライドによって前記接点部のうちの前記内面に近接する部分を覆う位置に配置する絶縁部材配置工程と、を備える。 The method for manufacturing the switch of the present invention comprises:
A switch for connecting an electric circuit on the primary side and an electric circuit on the secondary side so that it can be opened and closed,

上記構成の開閉器の製造方法によれば、絶縁部材配置工程では、絶縁部材が接点部のうちの筐体の内面に近接する部分を覆う位置に配置されるため、二次側端子部材を筐体に取り付けると、接点部と該接点部に近接する内面との間が絶縁部材によって遮られる。そのため、接点部の絶縁性を保ったまま接点部と前記内面との距離（絶縁距離）を小さくすることができる。従って、上記構成の開閉器の製造方法では、筐体の内面に対する接点部の絶縁性を確保するためのスペースを小さくすることができ、これにより、筐体を小型化できるようになっている。 According to the switch manufacturing method having the above configuration, in the insulating member arranging step, the insulating member is arranged at a position that covers the portion of the contact portion that is close to the inner surface of the housing. When attached to the body, the insulating member isolates the contact portion from the inner surface adjacent to the contact portion. Therefore, the distance (insulation distance) between the contact portion and the inner surface can be reduced while maintaining the insulation of the contact portion. Therefore, in the method for manufacturing the switch having the above configuration, the space for ensuring the insulation of the contact portion from the inner surface of the housing can be reduced, and thus the housing can be miniaturized.

かかる構成によれば、筐体を組みあげた後、挿込孔から筐体の外部に引き出したリード線用端子を端子本体部に接続しているため、リード線の長さはリード線用端子を筐体の外部に引き出せる長さに設定されていればよい。そのため、上記構成の開閉器の製造方法では、リード線の余長を少なくすることができ、これにより、二次側端子部材を挿込孔に挿し込んだ際に生じるリード線の弛みを抑えることができる。
リード線用端子と端子本体部との接続作業や、接点部への絶縁部材の取付作業は、筐体を組み上げた後、筐体内に収容されているリード線用端子や絶縁部材を挿込孔から筐体外に引き出しながら行われるため、リード線の長さが、接続元になる開閉部から筐体外の挿込孔付近の場所まで引き出せる長さに設定されていれば、それぞれの作業を行うことができる。そのため、リード線の余長を少なくすることができる。 According to this configuration, after the housing is assembled, the lead wire terminal pulled out from the housing through the insertion hole is connected to the terminal main body. is set to a length that can be pulled out of the housing.

さらに、端子本体部５０の先端面は平面となっている。なお、図示していないが、端子本体部５０には先端面で開口する螺子孔が形成されている。 Furthermore, the tip surface of the terminal body portion 50 is flat. Although not shown, the terminal main body 50 is formed with a screw hole that is open at the tip surface.

そのため、端子本体部５０の先端面に端子片部６１の片面を合わせた状態で端子片部６１に挿通したボルトＢを螺子孔に螺合させると端子片部６１が端子本体部５０に固定され、これにより、リード線用端子６と端子本体部５０とが接続されるようになっている。 Therefore, when the bolt B inserted through the terminal piece portion 61 is screwed into the screw hole in a state where one side of the terminal piece portion 61 is aligned with the tip surface of the terminal body portion 50 , the terminal piece portion 61 is fixed to the terminal body portion 50 . Thus, the lead wire terminal 6 and the terminal body portion 50 are connected.

なお、リード線用端子６と端子本体部５０とが接続されることで構成される接点部７とは充電部（筐体２の内面に対して絶縁する必要のある部分）のことであり、リード線用端子６や端子本体部５０の他、ボルトＢや芯線４０の絶縁被覆４１から露出している部分も含まれる。 The contact portion 7 formed by connecting the lead wire terminal 6 and the terminal body portion 50 is a charging portion (a portion that needs to be insulated from the inner surface of the housing 2). In addition to the lead wire terminal 6 and the terminal main body 50, the bolt B and the portion exposed from the insulating coating 41 of the core wire 40 are also included.

絶縁部材８は、有底筒状の第一絶縁部８０と、筒状であり、第一絶縁部８０の周面から延出するように構成され且つ内部の空間が第一絶縁部８０の内部の空間と連続する第二絶縁部８１と、を有する。 The insulating member 8 includes a bottomed cylindrical first insulating portion 80 and a cylindrical first insulating portion 80 extending from the peripheral surface of the first insulating portion 80 and having an internal space inside the first insulating portion 80. and a second insulating portion 81 that is continuous with the space of

第一絶縁部８０の内部と第二絶縁部８１の内部とはひとつながりの空間となっている。そのため、絶縁部材８は、第二絶縁部８１及び第一絶縁部８０の一方の先端開口から挿入したリード線４を第二絶縁部８１及び第一絶縁部８０の他方の先端開口から引き出すことができ、これにより、リード線４（より具体的にはリード線４の線方向）に沿わせながらスライド可能な状態になる。 The inside of the first insulating portion 80 and the inside of the second insulating portion 81 form a continuous space. Therefore, in the insulating member 8, the lead wire 4 inserted through one of the openings at the ends of the second insulating portion 81 and the first insulating portion 80 can be pulled out from the opening at the other end of the second insulating portion 81 and the first insulating portion 80. As a result, it becomes slidable along the lead wire 4 (more specifically, along the line direction of the lead wire 4).

第一絶縁部８０は、前記スライドにより、端子本体部５０に対して先端側から被せることができる。このようにすると、端子本体部５０、端子片部６１、ボルトＢが第一絶縁部８０によって覆われる。また、取付部６０、芯線４０の露出部分が第二絶縁部８１によって覆われるため、接点部７全体が絶縁部材８に収容された状態になる。 The first insulating portion 80 can cover the terminal body portion 50 from the tip side by sliding. By doing so, the terminal body portion 50 , the terminal piece portion 61 and the bolt B are covered with the first insulating portion 80 . Moreover, since the mounting portion 60 and the exposed portions of the core wire 40 are covered with the second insulating portion 81 , the entire contact portion 7 is housed in the insulating member 8 .

本実施形態に係る開閉器１の構成は以上の通りである。続いて、開閉器１の製造方法を説明する。図１に示す開閉器１の製造方法では、ケース２０とカバー２１とを分離した状態でケース２０に開閉部３を収容する開閉部収容工程と、該開閉部収容工程の後に、前記絶縁部材８を、リード線４の線方向でスライド可能となるようにしてリード線４に取り付ける絶縁部材取付工程と、該絶縁部材取付工程の後に、カバー２１をケース２０に取り付けて筐体２内のリード線用端子６を挿込孔２１０ａから筐体２の外部に引き出す筐体組立工程と、リード線用端子６と端子本体部５０とを接続して接点部７を形成する接点部形成工程と、絶縁部材８を、リード線４に沿わせてスライドさせて接点部７を覆う位置に配置する絶縁部材配置工程と、該絶縁部材配置工程の後に、二次側端子部材５を接点部７が筐体２内部に位置するように挿込孔２１０ａに挿し込む挿込工程とが行われる。 The configuration of the switch 1 according to this embodiment is as described above. Next, a method for manufacturing the switch 1 will be described. In the method for manufacturing the switch 1 shown in FIG. 1, the opening/closing portion housing step of housing the opening/closing portion 3 in the case 20 with the case 20 and the cover 21 separated, and the insulating member 8 after the opening/closing portion housing step. is attached to the lead wire 4 so as to be slidable in the wire direction of the lead wire 4, and after the insulating member attaching step, the cover 21 is attached to the case 20 and the lead wire in the housing 2 A housing assembly step of drawing out the terminal 6 for the lead wire from the insertion hole 210a to the outside of the housing 2, a contact portion forming step of connecting the lead wire terminal 6 and the terminal main body portion 50 to form the contact portion 7, and an insulating An insulating member arranging step of sliding the member 8 along the lead wire 4 and arranging it at a position covering the contact portion 7; 2 and an inserting step of inserting into the insertion hole 210a so as to be located inside.

開閉部収容工程では、ケース２０とカバー２１とを分離した状態でケース２０に開閉部３を収容するため、ケース２０はカバー２１に対して拘束されていない状態である。 In the opening/closing portion accommodating step, the opening/closing portion 3 is accommodated in the case 20 with the case 20 and the cover 21 separated, so the case 20 is not restrained from the cover 21 .

開閉部収容工程から絶縁部材取付工程に移る前に、開閉部３の二次側にリード線４を接続するリード線４接続工程を行う必要があるが、このリード線４接続工程は、絶縁部材取付工程の前であれば、開閉部収容工程の前に行ってもよいし、開閉部収容工程の後に行ってもよい。すなわち、リード線４は、開閉部３の二次側に接続された状態で開閉部３とともにケース２０内に収容されてもよいし、開閉部３をケース２０内に収容した後に該開閉部３の二次側に接続してもよい。 It is necessary to perform the lead wire 4 connection step of connecting the lead wire 4 to the secondary side of the switch portion 3 before moving from the opening/closing portion accommodating step to the insulating member attaching step. As long as it is before the mounting process, it may be performed before the opening/closing part accommodating process, or may be performed after the opening/closing part accommodating process. That is, the lead wire 4 may be accommodated in the case 20 together with the opening/closing portion 3 while being connected to the secondary side of the opening/closing portion 3, or may be housed in the opening/closing portion 3 after the opening/closing portion 3 is accommodated in the case 20. may be connected to the secondary side of

また、絶縁部材取付工程では、リード線用端子６を絶縁部材８の第二絶縁部８１から内部に挿入して絶縁部材８の第一絶縁部８０から外部に引き出すことにより、絶縁部材８にリード線４を通す（図２参照）。 In the insulating member mounting step, the lead wire terminal 6 is inserted into the insulating member 8 from the second insulating portion 81 and pulled out from the first insulating portion 80 of the insulating member 8, whereby the lead wire is attached to the insulating member 8. Pass the wire 4 (see FIG. 2).

筐体組立工程では、ケース２０の開放領域をカバー２１で塞ぐことにより筐体２を組み立てる。また、組みあげられた筐体２内には、開閉部３、リード線４、絶縁部材８が収容されているため、筐体組立工程では、接点部形成工程において端子本体部５０に接続するリード線用端子６を、挿込孔２１０ａから筐体２外に引き出す。 In the housing assembly process, the housing 2 is assembled by covering the open area of the case 20 with the cover 21 . In addition, since the opening/closing portion 3, the lead wire 4, and the insulating member 8 are accommodated in the assembled housing 2, the leads connected to the terminal body portion 50 in the contact forming process are not required in the housing assembling process. The wire terminal 6 is pulled out of the housing 2 from the insertion hole 210a.

接点部形成工程では、筐体２の外部で端子本体部５０にリード線用端子６を接続する（図３参照）。端子本体部５０にリード線用端子６を接続する場合は、端子本体部５０の先端面に端子片部６１の片面を接触させた状態で、端子片部６１に通したボルトＢを端子本体部５０の螺子孔に螺合させる。これにより、接点部７が形成され、端子本体部５０とリード線用端子６とが導通接続される。 In the contact portion forming step, the lead wire terminal 6 is connected to the terminal body portion 50 outside the housing 2 (see FIG. 3). When connecting the lead wire terminal 6 to the terminal body portion 50, one side of the terminal piece portion 61 is brought into contact with the tip surface of the terminal body portion 50, and the bolt B passed through the terminal piece portion 61 is inserted into the terminal body portion. It is screwed into the screw hole of 50. Thereby, the contact portion 7 is formed, and the terminal body portion 50 and the lead wire terminal 6 are electrically connected.

絶縁部材配置工程では、絶縁部材８をリード線４の線方向に沿ってリード線用端子６側にスライドさせることによって筐体２内から筐体２外に取り出した後、該絶縁部材８を接点部７に被せる。 In the insulating member arranging step, the insulating member 8 is slid along the wire direction of the lead wire 4 toward the lead wire terminal 6 side to take out the insulating member 8 from the housing 2 to the outside of the housing 2, and then the insulating member 8 is attached to the contact. Cover the part 7.

本実施形態では、第一絶縁部８０の先端開口を先頭にして絶縁部材８を端子本体部５０に被せる。このようにすると、端子本体部５０、端子片部６１、ボルトＢが第一絶縁部８０によって覆われ、また、取付部６０、芯線４０の露出部分が第二絶縁部８１によって覆われるため、接点部７全体が絶縁部材８に収容される。 In the present embodiment, the terminal body portion 50 is covered with the insulating member 8 with the tip opening of the first insulating portion 80 leading. With this configuration, the terminal main body portion 50, the terminal piece portion 61, and the bolt B are covered with the first insulating portion 80, and the mounting portion 60 and the exposed portion of the core wire 40 are covered with the second insulating portion 81, so that the contact The entire portion 7 is housed in the insulating member 8 .

これにより、端子片部６１の片面（端子本体部５０に接している片面）を含め、接点部７全体の周囲が絶縁部材８によって覆われる。 As a result, the insulating member 8 covers the entire periphery of the contact portion 7 including one side of the terminal piece portion 61 (one side in contact with the terminal body portion 50 ).

そのため、挿込工程において、二次側端子部材５を挿込孔２１０ａから筐体２の内部に挿し込むと（図４参照）、端子片部６１の前記片面と、前記片面に対向する筐体２の内面との間だけでなく、接点部７の周囲が筐体２の内面に対して遮られる（図１参照）。 Therefore, in the insertion step, when the secondary side terminal member 5 is inserted into the housing 2 through the insertion hole 210a (see FIG. 4), the one side of the terminal piece portion 61 and the housing facing the one side The periphery of the contact portion 7 is shielded from the inner surface of the housing 2 as well as the inner surface of the housing 2 (see FIG. 1).

従って、製造された開閉器１では、接点部７が絶縁部材８で覆われるため、筐体２の内面に対する接点部７の絶縁性が確保される。 Therefore, in the manufactured switch 1, the contact portion 7 is covered with the insulating member 8, so that the insulation of the contact portion 7 with respect to the inner surface of the housing 2 is ensured.

以上のように、本実施形態の開閉器１によれば、接点部７と該接点部７に近接する筐体２の内面との間に絶縁部材８が配置されるため、接点部７と前記近接する内面との絶縁性を保ったまま接点部７と前記近接する内面との距離（絶縁距離）を小さくすることができる。従って、上記構成の開閉器１では、筐体２の内面に対する接点部７の絶縁性を確保するためのスペースを小さくすることができ、これにより、筐体２を小型化できるようになっている。 As described above, according to the switch 1 of the present embodiment, the insulating member 8 is arranged between the contact portion 7 and the inner surface of the housing 2 adjacent to the contact portion 7. The distance (insulation distance) between the contact portion 7 and the adjacent inner surface can be reduced while maintaining insulation with the adjacent inner surface. Therefore, in the switch 1 configured as described above, the space for ensuring the insulation of the contact portion 7 with respect to the inner surface of the housing 2 can be reduced, so that the housing 2 can be miniaturized. .

また、挿込板部の板面（内面）の向きに端子片部６１の片面の向きを合わせて配置したリード線用端子６との間に絶縁部材８が配置されるため、リード線用端子６の設置スペースとともに筐体２の内面に対する接点部７の絶縁性を確保するためのスペースを小さくすることによって、筐体２を小型化できるようになっている。 In addition, since the insulating member 8 is arranged between the lead wire terminal 6 and the lead wire terminal 6 arranged with one side of the terminal piece portion 61 aligned with the direction of the plate surface (inner surface) of the insertion plate portion, the lead wire terminal The housing 2 can be miniaturized by reducing the installation space of the contact 6 and the space for ensuring insulation of the contact portion 7 with respect to the inner surface of the housing 2 .

そして、本実施形態の開閉器１の製造方法によれば、絶縁部材配置工程では、絶縁部材８が接点部７のうちの筐体２の内面に近接する部分を覆う位置に配置されるため、接点部７と該接点部７に近接する内面との絶縁性を保ったまま接点部７と前記内面との距離（絶縁距離）を小さくすることができる。従って、上記構成の開閉器１の製造方法では、筐体２の内面に対する接点部７の絶縁性を確保するためのスペースを小さくすることができ、これにより、筐体２を小型化できるようになっている。 According to the method for manufacturing the switch 1 of the present embodiment, in the insulating member placement step, the insulating member 8 is placed at a position covering the portion of the contact portion 7 that is close to the inner surface of the housing 2. The distance (insulation distance) between the contact portion 7 and the inner surface can be reduced while maintaining the insulation between the contact portion 7 and the inner surface adjacent to the contact portion 7 . Therefore, in the manufacturing method of the switch 1 having the above configuration, the space for ensuring the insulation of the contact portion 7 with respect to the inner surface of the housing 2 can be reduced, so that the housing 2 can be miniaturized. It's becoming

また、リード線用端子６と端子本体部５０の接続作業や、接点部６への絶縁部材８の取付作業は、筐体２を組み上げた後、筐体２内に収容されているリード線用端子６や絶縁部材８を挿込孔２１０ａから筐体２外に引き出しながら行われるため、リード線４の長さが接続元である開閉部３から筐体２外の挿込孔２１０ａ付近の場所まで引き出せる長さに設定されていれば、それぞれの作業を行うことができる。そのため、リード線４の余長を少なくすることができる。これに伴い、二次側端子部材５を挿込孔２１０ａに挿し込んだ際に生じるリード線４の弛みを抑えることができるため、筐体２の内面に対してリード線４の絶縁性を確保するためのスペースも小さくできる分、筐体２を小型化できるようになる。 Further, the operation of connecting the lead wire terminal 6 and the terminal main body 50 and the operation of attaching the insulating member 8 to the contact portion 6 are carried out after the housing 2 is assembled. Since the terminal 6 and the insulating member 8 are pulled out of the housing 2 from the insertion hole 210a, the length of the lead wire 4 is located near the insertion hole 210a outside the housing 2 from the opening/closing part 3, which is the connection source. If it is set to a length that can be pulled out, each work can be performed. Therefore, the extra length of the lead wire 4 can be reduced. As a result, it is possible to suppress the slack of the lead wires 4 that occurs when the secondary terminal member 5 is inserted into the insertion hole 210a, so that the insulation of the lead wires 4 with respect to the inner surface of the housing 2 is ensured. The housing 2 can be miniaturized to the extent that the space for mounting can also be reduced.

従って、本実施形態の開閉器１、及び開閉器１の製造方法によれば、筐体２の内面と筐体２内の充電部との絶縁距離を小さくできるようにすることによって、小型化できるという優れた効果を奏し得る。 Therefore, according to the switch 1 and the method for manufacturing the switch 1 of the present embodiment, the size can be reduced by reducing the insulation distance between the inner surface of the housing 2 and the charging portion in the housing 2. It can produce an excellent effect.

なお、本発明の開閉器１、及び開閉器１の製造方法は、上記実施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の変更を加え得ることは勿論である。 It should be noted that the switch 1 and the method for manufacturing the switch 1 of the present invention are not limited to the above-described embodiments, and of course various modifications can be made without departing from the gist of the present invention. .

The secondary side terminal member 5 may be attached to the cover side peripheral wall portion 211 of the cover 21, for example.

また、二次側端子部材５は、カバー２１ではなくケース２０に取り付けられていてもよい。 Also, the secondary side terminal member 5 may be attached to the case 20 instead of the cover 21 .

上記実施形態において、絶縁部材８は、接点部７の周囲を覆うように構成されていたが、この構成に限定されない。例えば、絶縁部材８は、接点部７全体のうち、筐体２に近接する部分だけを覆うように構成されていてもよい。このようにしても、接点部７と該接点部７に近接する筐体２の内面との間を絶縁部材８で遮ることができるため、筐体２の内面に対する接点部７の絶縁性を確保するためのスペースを小さくすることができる。 In the above embodiment, the insulating member 8 is configured to cover the contact portion 7, but the configuration is not limited to this. For example, the insulating member 8 may be configured to cover only a portion of the entire contact portion 7 that is close to the housing 2 . Even in this way, the contact portion 7 and the inner surface of the housing 2 close to the contact portion 7 can be shielded by the insulating member 8, so that the insulation of the contact portion 7 from the inner surface of the housing 2 is ensured. can reduce the space for
