Further, insertion holes 40c through which the mounting screws 41 are inserted are formed at the four corners of the upper surface of the transparent cover 40, respectively.

次に、分岐端子台装置１への電源入力側及び出力側のケーブル接続例について、図５及び図６を参照しつつ説明する。図５は、導電金具２０にケーブルを接続した状態を示す平面図である。図６は、分岐端子台装置１の使用状態を示す斜視図である。尚、図５では、透明カバー４０及び記号板３０の図示を省略している。また、分岐端子台装置１の各端子台部１１には、電源入力側（６００Ｖ−２５０Ａ）に１本の入力側ケーブル５０が接続され、電源出力側（６００Ｖ−８０Ａ）に３本の出力側ケーブル５２がそれぞれ接続される。また、分岐端子台装置１は、図示しないボルトを用いて配電盤に固定されているものとする。   Next, an example of cable connection on the power input side and output side to the branch terminal block device 1 will be described with reference to FIGS. 5 and 6. FIG. 5 is a plan view showing a state in which a cable is connected to the conductive metal fitting 20. FIG. 6 is a perspective view showing a use state of the branch terminal block device 1. In FIG. 5, illustration of the transparent cover 40 and the symbol plate 30 is omitted. In addition, one input side cable 50 is connected to the power input side (600V-250A), and three output sides are connected to the power output side (600V-80A) to each terminal block 11 of the branch terminal block device 1. Each cable 52 is connected. Moreover, the branch terminal block apparatus 1 shall be fixed to the switchboard using the volt | bolt which is not illustrated.

まず、透明カバー４０及び記号板３０をケース１０から取り外すと共に金具取付けネジ２６を弛めた状態で、入力側ケーブル５０を導電金具２０の上段端子面２２に接続する。すなわち、入力端子ボルト２７の足部を、座金と共に入力側ケーブル５０先端の圧着端子５０ａの孔に挿通し、さらに上段端子面２２のボルト挿通孔２２ｃに挿通し、螺合して締付けることにより、圧着端子５０ａを上段端子面２２に固着する。   First, the input side cable 50 is connected to the upper terminal surface 22 of the conductive metal fitting 20 with the transparent cover 40 and the symbol plate 30 removed from the case 10 and the metal fitting mounting screw 26 is loosened. That is, by inserting the foot portion of the input terminal bolt 27 together with the washer through the hole of the crimp terminal 50a at the tip of the input side cable 50, and further through the bolt insertion hole 22c of the upper terminal surface 22, screwing and tightening, The crimp terminal 50 a is fixed to the upper terminal surface 22.

次に、３本の出力側ケーブル５２のうちの２本を、導電金具２０の下段端子面２１に接続する。すなわち、出力端子ネジ２５の足部を、座金と共に２本の出力側ケーブル５２先端の圧着端子５２ａの孔にそれぞれ挿通し、下段端子面２１に設けられた２つのネジ孔２１ａにそれぞれ螺合して締付けることにより、２個の圧着端子５２ａを下段端子面２１に固着する。次いで、残り１本の出力側ケーブル５２を導電金具２０の上段端子面２２に接続する。すなわち、出力端子ネジ２５の足部を、座金と共に出力側ケーブル５２先端の圧着端子５２ａの孔に挿通し、上段端子面２２に設けられたネジ孔２２ａに螺合して締付けることにより、圧着端子５２ａを上段端子面２２に固着する。入力側ケーブル５０及び各出力側ケーブル５２の導電金具２０への接続が完了した後、２個の金具取付けネジ２６を締付けて導電金具２０をケース１０の台座部１３に固定する。他の端子台部１１についても、同様の作業を行うことにより、各々の入力側ケーブル５０及び出力側ケーブル５２の導電金具２０への接続と導電金具２０の台座部１３への固定を行う。   Next, two of the three output cables 52 are connected to the lower terminal surface 21 of the conductive metal fitting 20. That is, the foot portion of the output terminal screw 25 is inserted into the hole of the crimp terminal 52a at the tip of the two output side cables 52 together with the washer, and is respectively screwed into the two screw holes 21a provided in the lower terminal surface 21. The two crimp terminals 52a are fixed to the lower terminal surface 21 by tightening. Next, the remaining one output side cable 52 is connected to the upper terminal surface 22 of the conductive metal fitting 20. That is, the terminal of the output terminal screw 25 is inserted into the hole of the crimp terminal 52a at the tip of the output side cable 52 together with the washer, and is screwed into the screw hole 22a provided in the upper terminal surface 22 to be tightened. 52 a is fixed to the upper terminal surface 22. After the connection of the input side cable 50 and each output side cable 52 to the conductive fitting 20 is completed, the two fitting mounting screws 26 are tightened to fix the conductive fitting 20 to the pedestal portion 13 of the case 10. For the other terminal base parts 11, the same operation is performed to connect the input side cables 50 and the output side cables 52 to the conductive metal parts 20 and to fix the conductive metal parts 20 to the pedestal part 13.

全ての端子台部１１について上記作業が終了した後、記号板３０を、長手方向を左右に向けてケース１０の各側壁部１９及び各仕切り壁部１８上面における前後方向中央に載置する。そして、記号板３０下面に設けられたリブ３０ａを、ケース１０の各側壁部１９及び各仕切り壁部１８上部にそれぞれ嵌めるように位置決めする。   After the above operation is completed for all the terminal block portions 11, the symbol plate 30 is placed at the center in the front-rear direction on the upper surfaces of the side wall portions 19 and the partition wall portions 18 of the case 10 with the longitudinal direction turned to the left and right. And the rib 30a provided in the lower surface of the symbol board 30 is positioned so that it may each fit in each side wall part 19 of each case 10, and each partition wall part 18 upper part.

続いて、透明カバー４０を、ケース１０左右両側の側壁部１４上に位置合わせしつつ載置し、四隅の各挿通孔４０ｃに取付けネジ４１をそれぞれ挿通して側壁部１９上部に設けられた各雌ネジ金具１９ａにそれぞれ螺合することにより、透明カバー４０がケース１０上面を覆う状態で固定される。   Subsequently, the transparent cover 40 is placed on the side wall portions 14 on the left and right sides of the case 10 while being aligned, and the mounting screws 41 are respectively inserted into the insertion holes 40c at the four corners to be provided on the side wall portion 19 upper part. The transparent cover 40 is fixed in a state of covering the upper surface of the case 10 by being screwed into the female screw fitting 19a.

そして、各ケーブルが接続された分岐端子台装置１は、例えば、３つの端子台部１１に入力電源として６００Ｖ−２５０Ａの３相電源が接続されている場合には、Ｕ相，Ｖ相，及びＷ相に対応する６００Ｖ−８０Ａの出力電源に分岐する。   And the branch terminal block apparatus 1 to which each cable is connected, for example, when a three-phase power supply of 600V-250A is connected as input power to the three terminal block sections 11, U-phase, V-phase, and Branches to an output power supply of 600V-80A corresponding to the W phase.

以上詳述したことから明らかなように、段違いの二つの端子面である下段端子面２１及び上段端子面２２を有する３個の導電金具２０と、各導電金具２０が固定される階段状の３個の台座部１３を有する絶縁性の筐体としてのケース１０とを備え、各導電金具２０は、上段端子面２２に１個の入力端子ボルト２７が設けられると共に、下段端子面２１に２個の出力端子ネジ２５が、上段端子面２２に１個の出力端子ネジ２５がそれぞれ設けられているので、各導電金具２０並びにケース１０のサイズを小さく設定することができ、装置全体をコンパクト化することが可能となる。また、出力端子ネジ２５が設けられる下段端子面２１と上段端子面２２とが段違いとなっているため、各出力端子ネジ２５に接続される出力側ケーブル５２同士が干渉することがなく、各出力側ケーブル５２の各出力端子ネジ２５への接続作業を容易に行うことができる。   As is clear from the above detailed description, three conductive metal fittings 20 having a lower terminal surface 21 and an upper terminal surface 22 which are two different terminal surfaces, and a step-like 3 to which each conductive metal fitting 20 is fixed. Each of the conductive metal fittings 20 is provided with one input terminal bolt 27 on the upper terminal surface 22 and two on the lower terminal surface 21. Since the output terminal screw 25 is provided with one output terminal screw 25 on the upper terminal surface 22, the size of each conductive metal fitting 20 and the case 10 can be set small, and the entire apparatus is made compact. It becomes possible. In addition, since the lower terminal surface 21 and the upper terminal surface 22 provided with the output terminal screws 25 are different in level, the output cables 52 connected to the output terminal screws 25 do not interfere with each other, and each output The connection work of the side cable 52 to each output terminal screw 25 can be easily performed.

また、下段端子面２１に設けられた２個のネジ孔２１ａ及び上段端子面２２に設けられたネジ孔２２ａの水平位置は、ケーブル接続方向である前後方向と交差する左右方向において互いに異なるように設定されているので、メンテナンス時における各出力端子ネジ２５のネジ締め点検等において、下段端子面２１に取付けられた２個の出力端子ネジ２５を点検する際に、上段端子面２２の出力端子ネジ２５に接続された出力側ケーブル５２にドライバが接触することなく、出力端子ネジ２５の増す締め作業等を効率的に行うことができる。   Further, the horizontal positions of the two screw holes 21a provided in the lower terminal surface 21 and the screw holes 22a provided in the upper terminal surface 22 are different from each other in the left-right direction intersecting the front-rear direction which is the cable connection direction. Therefore, when checking the two output terminal screws 25 attached to the lower terminal surface 21 in the screw tightening inspection or the like of each output terminal screw 25 at the time of maintenance, the output terminal screws of the upper terminal surface 22 are checked. The output terminal screw 25 can be efficiently tightened without the driver contacting the output-side cable 52 connected to the output terminal cable 25.

また、導電金具２０において隣接する下段端子面２１と上段端子面２２との間を接続する立ち上がり部２３が、下段端子面２１に設けられる出力端子ネジ２５に近接しているので、出力側ケーブル５２先端の圧着端子５２ａを下段端子面２１の出力端子ネジ２５に取付ける際に、圧着端子５２ａの先端が導電金具２０の略垂直な壁面形状をなす立ち上がり部２３に当接して位置決めされ、高い作業性で出力側ケーブル５２を容易に接続することができる。   Further, since the rising portion 23 connecting the adjacent lower terminal surface 21 and the upper terminal surface 22 in the conductive metal fitting 20 is close to the output terminal screw 25 provided on the lower terminal surface 21, the output side cable 52. When attaching the crimp terminal 52a at the distal end to the output terminal screw 25 of the lower terminal surface 21, the distal end of the crimp terminal 52a is positioned in contact with the rising portion 23 having a substantially vertical wall surface shape of the conductive metal member 20, and high workability is achieved. Thus, the output side cable 52 can be easily connected.

また、ケース１０の左右両端に側壁部１９がそれぞれ立設されると共に、側壁部１９に着脱可能に取付けられてケース１０上面を覆う透明カバー４０を備えているので、作業者が通電中の導電金具２０等に誤って接触して感電する事故等を防止することができると共に、透明カバー４０を取付けた状態で入力端子ボルト２７や出力端子ネジ２５における各ケーブルの接続状態等の目視確認を行うことができる。   Further, the side wall portions 19 are provided upright at both the left and right ends of the case 10, and the transparent cover 40 that is detachably attached to the side wall portion 19 and covers the upper surface of the case 10 is provided. It is possible to prevent accidents such as accidental contact with the metal fitting 20 or the like and to visually check the connection state of each cable at the input terminal bolt 27 and the output terminal screw 25 with the transparent cover 40 attached. be able to.

また、ケース１０の左右方向長さに略等しい長さを有する記号板３０が両側壁部１９上面に架け渡されて透明カバー４０下面との間に挟持されるので、簡単な構造で確実に記号板４０が固定されると共に、記号板４０に表示された各ケーブルを識別するための記号等を、透明カバー４０を通して確実に目視確認することができる。   Further, since the symbol plate 30 having a length substantially equal to the length in the left-right direction of the case 10 is bridged between the upper surfaces of the side wall portions 19 and is sandwiched between the lower surfaces of the transparent covers 40, the symbols can be reliably and easily constructed. While the plate 40 is fixed, a symbol or the like for identifying each cable displayed on the symbol plate 40 can be surely visually confirmed through the transparent cover 40.
