Abstract: The invention concerns a shunting lattice for electrical distributors that conduct the same potential, such as, e.g., PE ground conductors or reference lines, and it is proposed to arrange a two-dimensional surface structure in the form of a metal plate, an expanded metal grid or the like on the installation side of the shunting lattice, and this plate carries a mounting rail on which conventional, commercially available conductor supply terminals of large cross section are to be locked to the mounting rail with contact.

Abstract: The invention concerns a transformer terminal, which consists of two parts according to the instructions of the invention, i.e., a saddle contact, which has the internal connection unit and which locks onto the coil unit of the transformer or is configured in one piece with the latter, and a slide contact for the external wiring, preferably in the form of individual terminals that can be arranged in series, which can be plugged onto the saddle contact. In this way, a very easily accessible and robot-accessible arrangement of the internal connection units is achieved, which assures, however, a complete contact protection also for the transformer terminals mounted in the finished state.

Abstract: The invention relates to I/O devices for a data bus, which are configured as series terminals having an I/O electronic means installed therein (so-called bus terminals). The terminals are locatable on commercially available support rails and form there a terminal bus. Incorporated in the bus terminals are, power supply lines. A power supply electrically communicates with the power supply lines, the lines being automatically contacted or slipped therethrough upon location on the support rail.

Abstract: The invention concerns switchable serial terminals with a switching lever gripping component consisting of an insulating material. It is suggested that one provide the gripping component with two visual surfaces--of which in each of the two switching positions of the switching lever and in an alternating manner--one visual surface is turned toward the viewing direction of the operator and, in the same switching position, the other visual surface is turned away from the viewing direction of the operator.

Abstract: A series terminal with two supply line contact points for two-wire power supply to electrical or electronic components, especially initiators, with the supply line contact points being supplied with power through bridges starting from a feeder terminal. It is proposed to design the series terminal in a certain way so that it can be used at the same time as a feeder terminal. This is achieved by the fact that the bridge connectors for the supply line contact points are positioned with mirror symmetry relative to a plane of symmetry, but with the supply line contact points being on the same side of the plane of symmetry, and that the assembly rail latch base points of the series terminal have the same perpendicular distances relative to a central plane, with this central plane at the same time being the aforementioned plane of symmetry.

Abstract: Mutually mating cable contact members, on longitudinally aligned contact carriers, are surrounded by annular sealing portions of these carriers, which have annular sealing surfaces engaging each other. Said sealing portions consist of materials having different elasticities. A ring surrounds the sealing portion of greater elasticity and presses the sealing surface of this portion against the sealing portion of the other contact carrier. By the coaction of the ring with the sealing portions of different elasticities, the new connector remains water tight when submerged in deep water for extended periods of time.
