Abstract
A cross connection link which can establish several electrical connections between an elongated strip-shaped conductor and one or more bus bars in the recess of a terminal block has a series of neighboring L-shaped or U-shaped metallic distancing elements each of which has a leg connected with an edge portion of the strip-shaped conductor by a weakened joint so that it can be readily broken off the strip-shaped conductor, and a web which is integral with the other end portion of the leg and has an aperture for the shank of a screw serving to connect the web with a bus bar. The heads of the screws are adjacent to those sides of the webs which face the strip-shaped conductor, and such heads are confined against movement away from the regions of the respective webs so that they are always ready for engagement by the working end of a tool which is used to move the shanks of selected screws or all screws into mesh with tapped holes in the bus bar or bars. The confining means can constitute portions of the distancing elements or discrete cages consisting of electrically insulating material and connected to each other by an elongated enclosure which surrounds at least the major portion of…
