Description

【0001】
【発明の属する技術分野】
本発明は、プラグインブレーカと組み合わせて用いる接続変換部材に関するものである。
【0002】
【従来の技術】
【特許文献1】
特開2001−157323号公報(図10,11)
【0003】
分電盤などにおいては、母線バーに差込み接続できるプラグインブレーカが、接続作業性の良さを評価されて普及しつつある。これに伴い、分電盤の主幹バーの一次送りや二次送りとしても、プラグインブレーカを用いることが望まれる。ところが一次送り線や二次送り線は通常は単なる電線であるから、そのままプラグインブレーカを接続することはできない。
【0004】
そこで上記の特許文献1に示されるように、端子台の片側に差込み刃を設け、反対側にねじ付き端子を設けた接続変換装置が提案されている。この接続変換装置を用いれば、電線である送り線とプラグインブレーカとを接続することができる。しかしこのような端子台型の接続変換装置はコストがかかり、ある程度の設置スペースを必要とし、簡便に接続可能というプラグインブレーカの利点を生かすことができなかった。またねじ付き端子と電線との接続部が緩む可能性があった。
【0005】
【発明が解決しようとする課題】
本発明は上記した従来の問題点を解決し、電線とプラグインブレーカとを、設置スペースを必要とせず、低コストで確実に接続することができる新規な接続変換部材を提供するためになされたものである。
【0006】
【課題を解決するための手段】
上記の課題を解決するためになされた本発明の接続変換部材は、金具本体の一端に電線圧着部を形成し、他端にプラグイン挿入片を形成した接続変換部材であって、金具本体をカバーするとともに全体をプラグインブレーカのプラグイン端子に固定する保持部材を備え、この保持部材のプラグインブレーカへの係止部をプラグインブレーカの導体導入溝に対応させて設けるとともに、この係止部の先端をプラグインブレーカの導体導入溝の入口よりも厚く成形したことを特徴とするものである。なお、プラグイン挿入片の先端部を折曲形成した構造とすることが好ましく、金具本体が直線状の金属板からなり、その板厚中心と折曲形成した先端部の中心とを一致させた構造とすることが好ましい。
【0007】
本発明の接続変換部材は、金具本体の一端に電線圧着部を形成し、他端にプラグイン挿入片を形成したものであるから、電線圧着部に電線を圧着固定し、反対側のプラグイン挿入片をプラグインブレーカの導体導入溝に差し込むだけで、電線とプラグインブレーカとを簡単に接続することができる。
【0008】
【発明の実施の形態】
以下に本発明の好ましい実施形態を示す。
図1は本発明の接続変換部材の斜視図、図2はその正面図である。これらの図において、1は導電性に優れた金属よりなる金具本体、2はその一端に形成された電線圧着部、3はその他端に形成されたプラグイン挿入片である。金具本体1は好ましくは直線状に延びる金属板であり、この金属板の一端を丸めて電線圧着部2が形成されている。
【0009】
この電線圧着部2における電線の圧着が容易に行えるようにするために、金属板の板厚はあまり厚くすることは好ましくない。しかしプラグイン挿入片3はプラグイン端子との接続を確実に行わせるために、適度の厚さが必要となる。そこで図示のように、金属板を薄板としておきその他端を折曲形成することにより適度の厚みとすることが好ましい。また折曲した先端部4がR形状になり、プラグイン端子に差し込み易くなる。この実施形態では折り曲げは1回であるが、2回以上行うことも可能である。なお、電線圧着部2は成形前に金属板を潰し工程により薄く成形し、圧着を容易化しておくことが好ましい。また図2に示すように、金具本体の板厚中心と折曲形成した先端部4の中心とを一致させておけば、差し込み時に屈曲しにくくなるので好ましい。
【0010】
このような接続変換部材は、図3に示すようにプラグインブレーカ10のプラグイン端子5にプラグイン挿入片3を差し込み、電線圧着部2に電線6を圧着して用いられる。このように本発明の接続変換部材を用いれば、電線6とプラグインブレーカとを設置スペースを必要とせず、低コストで接続することができる。しかも電線6との接続は圧着により行われるので、ネジとは異なり緩むおそれもない上、簡便に接続可能である。
【0011】
本発明の接続変換部材は単独でも使用できるが、図4以下に示すように樹脂製の保持部材7に組み込んで使用することができる。保持部材7は接続変換部材の金具本体1をカバーするとともに、全体をプラグインブレーカ10に固定し、さらに金具本体1同士の絶縁部材の役割を持つものである。図4は保持部材7の半割部分を示すもので、2個を組み合わせ上下の係合片8を他方の係合溝9に係合させて用いられる。図5に示すように、保持部材7は接続変換部材の金具本体1を嵌め込んで支持できるスリット11を内部に3相分備え、任意のスリット8に接続変換部材を保持させることができる。なお、保持部材に組み込んだ電線圧着部には図示しない絶縁キャップが嵌めてある。
【0012】
また、保持部材7は側方にプラグインブレーカ10への係止部12を備えている。図7〜図9に示すように、保持部材7はプラグインブレーカ10の端子部の外側から被せるように取り付けられる。係止部12をプラグインブレーカの導体導入溝13に対応させて設けるとともに、この係止部12の先端を図4に示すようにプラグインブレーカ10の導体導入溝13の入口よりも厚く成形しておけば、プラグインブレーカ10の端子部に弾性的に係合させて固定することができる。すなわち、係止部12の先端の内側に傾斜部12aを設けることにより、係止部12が導体導入部13の入口を通過するときに一度外側に撓み、導体導入部13に入った後に再び元に戻るものである。しかしプラグインブレーカ10への取付方法はこれに限定されるものではなく、ネジによってもよい。
【0013】
このように本発明の接続変換部材を保持部材7に組み込んで使用すれば、ワンタッチでプラグインブレーカ10の端子部への取付が可能である。また前記したように、金具本体の板厚中心と折曲形成した先端部4の中心とを一致させておけば、図6に示すように保持部材7への組み込み時に方向性を気にする必要がない。保持部材7の電線圧着部2への電線6の圧着作業は、保持部材7への組み込み前、組み込み後の何れでもよい。
【0014】
なお、図10に示すようにプラグイン挿入片3にネジ孔14を形成しておけば、本発明の接続変換部材をネジ端子にネジ止めして接続することも可能となる。
【0015】
【発明の効果】
以上に説明したように、本発明の接続変換部材を用いれば、電線とプラグインブレーカのプラグイン端子とを簡単に接続することができる。しかも本発明の接続変換部材は端子台型のものとは異なり設置スペースを必要とせず、低コストである。また電線を圧着により固定するので、ネジ止め式のものとは異なり緩むおそれもない。さらに請求項4以下のように保持部材と組み合わせれば、プラグインブレーカの端子部への取付をワンタッチで行うことができる。よって本発明の接続変換部材は、分電盤の一次送りや二次送りとしてプラグインブレーカを用いる場合などに好適なものである。

DETAILED DESCRIPTION OF THE INVENTION
Preferred embodiments of the present invention are shown below.
FIG. 1 is a perspective view of a connection conversion member of the present invention, and FIG. 2 is a front view thereof. In these drawings, 1 is a metal fitting body made of a metal having excellent conductivity, 2 is a wire crimping portion formed at one end thereof, and 3 is a plug-in insertion piece formed at the other end. The metal fitting body 1 is preferably a metal plate extending linearly, and one end of the metal plate is rounded to form an electric wire crimping portion 2.
[0009]
In order to facilitate the crimping of the electric wire in the electric wire crimping portion 2, it is not preferable to make the metal plate too thick. However, the plug-in insertion piece 3 needs an appropriate thickness in order to ensure connection with the plug-in terminal. Therefore, as shown in the figure, it is preferable that the metal plate is a thin plate and the other end is bent to form an appropriate thickness. Further, the bent tip portion 4 has an R shape and is easily inserted into the plug-in terminal. In this embodiment, the bending is performed once, but can be performed twice or more. In addition, it is preferable that the electric wire crimping part 2 facilitates the crimping by forming a thin metal plate by a crushing process before molding. Also, as shown in FIG. 2, it is preferable to make the center of the thickness of the metal fitting body coincide with the center of the bent tip 4 so that it is difficult to bend when inserted.

Further, the holding member 7 includes a locking portion 12 to the plug-in breaker 10 on the side. As shown in FIGS. 7 to 9, the holding member 7 is attached so as to be covered from the outside of the terminal portion of the plug-in breaker 10. The locking portion 12 is provided so as to correspond to the conductor introduction groove 13 of the plug-in breaker, and the tip of the locking portion 12 is formed thicker than the inlet of the conductor introduction groove 13 of the plug-in breaker 10 as shown in FIG. Then, it can be elastically engaged with the terminal part of the plug-in breaker 10 and fixed. That is, by providing the inclined portion 12 a on the inner side of the tip of the locking portion 12, the locking portion 12 bends outward once when passing through the inlet of the conductor introducing portion 13, and after entering the conductor introducing portion 13, the original is again restored. Return to. However, the attachment method to the plug-in breaker 10 is not limited to this, and may be a screw.
[0013]
Thus, if the connection conversion member of the present invention is incorporated in the holding member 7 and used, the plug-in breaker 10 can be attached to the terminal portion with a single touch. Further, as described above, if the center of the thickness of the metal fitting body and the center of the bent tip portion 4 are made to coincide with each other, it is necessary to care about the directionality when assembling the holding member 7 as shown in FIG. There is no. The crimping operation of the electric wire 6 to the electric wire crimping portion 2 of the holding member 7 may be performed either before or after incorporation into the holding member 7.
[0014]
In addition, if the screw hole 14 is formed in the plug-in insertion piece 3 as shown in FIG. 10, it is also possible to connect the connection conversion member of the present invention by screwing to the screw terminal.
