    Abstract: A plurality of wide flat insulated bus bars are compressed in flatwise adjacent relationship between inwardly bowed aluminum side members and formed sheet metal edge caps. The side members have reflex portions formed along opposite edges which extend angularly outward and are cammed inward by rail portions on the caps to compress the sides substantially flat on the bus bars and bias the bus bars firmly together. The resiliently bowed sides and reflex portions compensate in assembly for an accumulation of tolerances in the bus bars and their insulation. Bolts are used to secure the sides and caps together, and exaggerated clearance openings are provided for the bolts to permit the caps to be forced firmly against the bus bars with the bolts loosely in place before being finally secured.

    Abstract translation: 多个宽扁平绝缘汇流条在向内弯曲的铝侧部件和成形的金属板边缘盖之间以平面相邻的关系被压缩。 侧面构件具有沿相反边缘形成的反射部分，该反射部分成角度地向外延伸，并且通过盖上的轨道部分向内凸起，以压缩汇流条上基本上平坦的两侧并将汇流条偏置在一起。 弹性弯曲的侧面和反射部分在组装时补偿母线中的公差和它们的绝缘体的积累。 螺栓用于将侧面和盖子固定在一起，并且为螺栓提供夸张的间隙开口，以允许将盖子牢固地压靠在母线上，同时螺栓松动地固定在最终固定之前。

    Abstract: Individual bus bars are insulated between their offset ends by two pairs of preformed U-shaped insulator strips having unequal length legs, the insulators of the respective pairs being slipped over the bar from opposite edges with the longer leg of each adjacent, and preferably tucked under, the shorter leg of the other and the second pair being disposed oppositely of the first pair. The offset ends are insulated either by a spiral wrap of insulating tape or a dip coating of insulation, each applied to overlap the ends of the preformed insulators. Three or four individually insulated bus bars are assembled with offset ends flared apart and have a preformed elongated rectangular insulator, slit along one side, disposed around the assembly between the innermost bends of the offset ends. The complete assembly between the offset portions is then tightly encased within a metallic housing.

    Abstract translation: 单个汇流条在其偏移端之间通过两对具有不等长度的支脚的预成型的U形绝缘条绝缘，各对的绝缘体从相对的边缘滑过该条，每个相邻的较长的支脚被折叠在下面 ，另一个的较短的腿和第二对被布置成与第一对相对。 偏移端通过绝缘带的螺旋卷绕或绝缘的浸渍涂层绝缘，每个涂层覆盖预成型绝缘体的端部。 三个或四个单独绝缘的汇流条组装有偏移端部分开，并且具有预制的细长矩形绝缘体，沿着一侧设置的狭缝，围绕组件在偏置端的最内弯曲之间设置。 然后将偏移部分之间的完整组件紧紧地包裹在金属外壳内。
