この発明による実施の形態１を図１ないし図４について説明する。図１は実施の形態１における全体構成を示す正面図である。図２は実施の形態１における全体構成を示す側面図である。図３は実施の形態１における盤間接続装置の構成を示す斜視図である。図４は実施の形態１における盤間接続装置に遮断器用接続部材を取り付けた構成を示す斜視図である。
【０００８】
この実施の形態１における盤間接続装置は、全体として、図１および図２に示すように構成される。
それぞれ配電盤１０からなる配電盤（１）と配電盤（２）との相互間における盤間接続部に、盤間接続装置が設けられる。
この盤間接続装置には、母線１を支持する接続装置本体２が設けられ、絶縁物からなる接続装置本体２は接地電位等の所定の電位に保持されるフレーム部材３に取り付けられている。
母線１は、図１に示す奥行方向に、３相分が互いに間隔を置いて並設されているものである。３相分のこれら母線１に対応して、図２に示すように、接続装置本体２が設けられる。
絶縁物部分２２で構成される接続装置本体２には、母線接続用接続部および遮断器接続用フィンガコンタクトを取り付け可能な遮断器接続用接続部１２を有する導電接続部材２１が設けられている。その詳細は、図３以下について後述する。
【０００９】
配電盤（１）または配電盤（２）を構成する配電盤１０は、図２に示すように、前面部１０Ｆおよび後面部１０Ｒを有し、この配電盤１０には、遮断器本体１１が収容され、遮断器接続用フィンガコンタクトが取り付けられた遮断器接続用接続部１２を有する接続装置本体２を介して母線１に接続されている。
遮断器本体１１は、図示下降位置において、その遮断器接続用接続部１２との接続を開放し断路位置となっている。
遮断器本体１１を昇降機構（図示せず）により図示下降位置から上方へ移動し上昇位置とすることによって、遮断器本体１１は通電状態を保持する通電位置となる。この状態で遮断器本体１１の導体５３は遮断器接続用接続部１２の遮断器接続用フィンガコンタクトに接触し通電を確保する。
【００１０】
図３に示すように、接続装置本体２は、銅のバルク材からなる導電接続部材２１と成型絶縁材からなる絶縁物部分２２とを有している。
直方体をなす導電接続部材２１は、図示上面および両側面を絶縁物部分２２により覆われ、図示下面を露出して絶縁物部分２２と一体に成型されている。

フィンガコンタクト５２は、遮断器側導体５３と接離可能に設けられる。遮断器側導体５３との接合状態において遮断器本体１１（図２参照）を母線１に接続し、遮断器本体１１の引出し方向の移動による遮断器側導体５３との接合の開放によって、断路状態となる。
【００１２】
実施の形態１に示すように盤間接続用の母線を構成することで、埋金２３で筐体に設けられたフレーム部材３に固定でき、絶縁物部分２２で絶縁距離が確保できる。
また、図４で示したように、この母線に遮断器との接続を行うためのフィンガーコンタクトを取付けるため、実施の形態１のように構成すると、盤間接続用の母線は、元からある盤間接続機能と碍子等による絶縁支持機能、遮断器接続機能を持つことになる。このため、組立作業の簡略化と部品点数の削減が可能になる。
