参照图3和图4，移动导电板32包括第一导电片35、第二导电片36和盖板41，第一导电片35为平整的片状结构，其固定在移动绝缘板33上，中间具有条形孔35a；第二导电片36具有与第一导电片35大小相同的条形孔36a，且当第一导电片35和第二导电片36交叉层叠时，二者的条形孔35a、36a可重合。移动导电板32包括有多组，组的数目与导电排1的数目相对应，各组之间通过插入到条形孔35a和36a内的螺栓37连接紧固，螺栓37与移动导电板32之间配有垫圈38。在第二导电片36上与第一导电片35层叠部设置有阶梯状的隆起36b，隆起36b的高度与第一导电片35的厚度相同，这样，第一导电片35与第二导电片36相互叠置时，叠置后的表面呈一平坦面，使二者与盖板41保持良好接触。Referring to FIGS. 3 and 4, the movable conductive plate 32 includes a first conductive sheet 35, a second conductive sheet 36, and a cover plate 41. The first conductive sheet 35 is a flat sheet-like structure that is fixed on the movable insulating plate 33 in the middle. There is a strip hole 35a; the second conductive sheet 36 has a strip hole 36a of the same size as the first conductive sheet 35, and when the first conductive sheet 35 and the second conductive sheet 36 are stacked, the strip holes 35a of the two 36a can overlap. The movable conductive plate 32 includes a plurality of groups, the number of which corresponds to the number of the conductive rows 1, and the groups are connected and fastened by bolts 37 inserted into the strip holes 35a and 36a, and the bolts 37 and the movable conductive plates 32 are connected. A gasket 38 is provided between them. A stepped ridge 36b is provided on the second conductive sheet 36 and the laminated portion of the first conductive sheet 35. The height of the ridge 36b is the same as the thickness of the first conductive sheet 35. Thus, the first conductive sheet 35 and the second conductive sheet 36 are formed. When stacked on each other, the stacked surfaces have a flat surface so that they are in good contact with the cover 41.
各组移动导电板32之间均设置一个板簧39，可使移动导电板32与移动绝缘板33之间、移动导电32与移动导电板32之间以及第一导电片35与第二导电片36之间为弹性支撑，使第一导电片35与第二导电片36始终保持良好电接触。板簧39为绝缘材料制成，或板簧39为金属材料但其与移动导电板32之间增设绝缘板42。A leaf spring 39 is disposed between each set of moving conductive plates 32 to move between the movable conductive plate 32 and the moving insulating plate 33, between the movable conductive 32 and the moving conductive plate 32, and between the first conductive sheet 35 and the second conductive sheet. The elastic support between 36 makes the first conductive sheet 35 and the second conductive sheet 36 always maintain good electrical contact.

Since the first conductive sheet 35 and the second conductive sheet 36 are laminated and then fastened by the bolts 37, when the first conductive sheet 35 slides, the bolts 37 are moved in the strip holes 35a, 36a until the bolts 37 move to the strip shape. The ends of the holes 35a, 36a. The first conductive sheet 35 is connected to the conductive row 1 through the second conductive sheet 36. Therefore, only the connection terminal is added to the first conductive sheet 35, and the terminal group formed by the first conductive sheet 35 can form a power distribution branch. , thereby extending the effective length of the busway, making the busway a variable-capacity busway.
为进一步增加母线槽的有效长度，可变容连接器3的移动导电板32还包括延长导电片40，其位于第一导电片35与第二导电片36之间，中间具有条形的固定孔40a。这样，第一导电片35与第二导电片36可相对错位三个条形状孔的距离，延长效果较为明显。In order to further increase the effective length of the busbar slot, the movable conductive plate 32 of the variable-capacity connector 3 further includes an elongated conductive sheet 40 between the first conductive sheet 35 and the second conductive sheet 36 with a strip-shaped fixing hole in the middle. 40a. Thus, the distance between the first conductive sheet 35 and the second conductive sheet 36 can be relatively offset by three strip-shaped holes, and the effect of the extension is more obvious.
综上所述，本实用新型的变容母线槽因采用可自由伸缩的错位滑动式移动导电板32连接方式，只需推动移动绝缘板33，即可延长变容母线槽的有效长度，延长长度可自由选择。在第一导电片35上安装连接端子后，不仅可延长母线槽的长度，还可作为母线槽的一个配电支路，以满足不同用户，不用施工环境的需求。而且使用方便，可靠，也可作为普通标准母线槽使用。In summary, the variable-capacity busway of the present invention is connected by a displaceable sliding type movable conductive plate 32 which can be freely stretched, and only the movable insulating plate 33 can be pushed to extend the effective length of the variable-capacity busway and extend the length. Free to choose. After the connection terminal is mounted on the first conductive sheet 35, not only the length of the busway can be extended, but also a power distribution branch of the busway can be used to meet different users without the need of a construction environment. It is easy to use and reliable, and can also be used as a common standard busway.
