Description

本発明は、マルチタップに関するものである。   The present invention relates to a multi-tap.

従来より、プラグが接続されるプラグ接続口を複数備え、プラグ接続口毎に設けられた操作ハンドルのオン／オフ操作に応じて、各プラグ接続口からの給電をオン／オフするテーブルタップが提供されている（例えば特許文献１参照）。   Conventionally, a plurality of plug connection ports to which plugs are connected are provided, and a table tap is provided to turn on / off the power supply from each plug connection port according to the on / off operation of the operation handle provided for each plug connection port. (For example, refer to Patent Document 1).

図７は特許文献１のテーブルタップに用いられるスイッチブロック１００の分解斜視図であり、このスイッチブロック１００は、一対の刃受ばね１０１，１０１を複数組（図７では３組）備えるとともに、外部電線（図示せず）が接続され、当該外部電線から供給される電力を各組の刃受ばね１０１，１０１に供給する一対のリード板１０２，１０２と、可動接点１０３ａと固定接点１０３ｂとで構成され、操作ハンドル１０４のオン／オフ操作に応じて一方の刃受ばね１０１と一方のリード板１０２との間を電気的に接続し、又は開離させる接点部１０３とを備える。各組の他方の刃受ばね１０１は何れも他方のリード板１０２と一体に設けられており、一方のリード板１０２には複数（図７では３個）の固定接点１０３ｂが一体に設けられている。   FIG. 7 is an exploded perspective view of the switch block 100 used for the table tap of Patent Document 1. This switch block 100 includes a plurality of pairs of blade receiving springs 101, 101 (three sets in FIG. 7) and an external part. An electric wire (not shown) is connected, and is composed of a pair of lead plates 102 and 102 that supply electric power supplied from the external electric wire to each pair of blade receiving springs 101 and 101, a movable contact 103a, and a fixed contact 103b. And a contact portion 103 for electrically connecting or separating one of the blade receiving springs 101 and one of the lead plates 102 in accordance with an on / off operation of the operation handle 104. Each of the other blade receiving springs 101 of each set is provided integrally with the other lead plate 102, and a plurality of (three in FIG. 7) fixed contacts 103b are provided integrally on one lead plate 102. Yes.

このテーブルタップによれば、操作ハンドル１０４がオフ側にあるときは可動接点１０３ａと固定接点１０３ｂとが接触していないため、一方の刃受ばね１０１と一方のリード板１０２とが開離した状態にあり、電力は供給されない。この状態から操作ハンドル１０４をオン側に切り替えると、可動接点１０３ａと固定接点１０３ｂとが接触することで一方の刃受ばね１０１と一方のリード板１０２とが電気的に接続され、電力が供給される。   According to this table tap, when the operation handle 104 is on the off side, the movable contact 103a and the fixed contact 103b are not in contact with each other, so that one blade receiving spring 101 and one lead plate 102 are separated. And no power is supplied. When the operation handle 104 is switched to the ON side from this state, the movable contact 103a and the fixed contact 103b come into contact with each other, so that one blade receiving spring 101 and one lead plate 102 are electrically connected, and electric power is supplied. The

特開２００４−２２１０３５号公報（段落［００１０］−段落［００２３］、及び、第１図）JP 2004-221035 A (paragraph [0010] -paragraph [0023] and FIG. 1)

上述の特許文献１に示したテーブルタップでは、一方のリード板１０２にはプラグ接続口の口数に合わせた固定接点１０３ｂが一体に設けられ、他方のリード板１０２にはプラグ接続口の口数に合わせた刃受ばね１０１が一体に設けられているため、プラグ接続口の口数を変更する場合にはその口数に合わせたリード板１０２を製作する必要があり、そのためプラグ接続口の口数に応じて複数の金型を用意しなければならず、金型費用が高くなるものであった。   In the table tap shown in Patent Document 1 described above, one lead plate 102 is integrally provided with a fixed contact 103b corresponding to the number of plug connection ports, and the other lead plate 102 is matched to the number of plug connection ports. Since the blade receiving springs 101 are integrally provided, when changing the number of plug connection ports, it is necessary to manufacture the lead plate 102 corresponding to the number of plug connection ports. Therefore, the mold cost was high.

本発明は上記問題点に鑑みて為されたものであり、その目的とするところは、金型費用を低減させたマルチタップを提供することにある。   The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a multi-tap with reduced mold costs.

The module corresponds to a plurality of blade receiving members to which the plug blades of the plug are respectively connected, a plurality of terminal plates respectively connected to the plurality of lead plates, and at least one blade receiving member according to the operation of the operation unit. And a contact portion for electrically connecting to or separating from the terminal board.

このマルチタップにおいて、各端子板と対応するリード板との接合部が同一面に設けられているのが好ましい。   In this multi-tap, it is preferable that the joint portion between each terminal plate and the corresponding lead plate is provided on the same surface.

また、このマルチタップにおいて、接合部がかしめ手段で構成されているのも好ましい。   In this multi-tap, it is also preferable that the joint portion is constituted by caulking means.

さらに、このマルチタップにおいて、接点部は、固定接点と、操作部の操作に応じて固定接点に接離自在に接触する可動接点とで構成され、少なくとも１つの刃受部材に固定接点が設けられているのも好ましい。   Further, in this multi-tap, the contact portion is composed of a fixed contact and a movable contact that comes in contact with and separates from the fixed contact according to the operation of the operation portion, and the fixed contact is provided on at least one blade receiving member. It is also preferable.

また、このマルチタップにおいて、プラグ接続モジュールを位置決めするための位置決め手段が各リード板にそれぞれ設けられているのも好ましい。   In this multi-tap, it is also preferable that positioning means for positioning the plug connection module is provided on each lead plate.
