  • the connection contact is part of a contact plate which is provided with the clamp and the clamping screw.
  • connection adapter of the type mentioned in the introduction in which the dimension in the longitudinal direction of the busbars can be kept very small, even with a three-wire busbar system, without fear that a short circuit between adjacent ones when the connection adapter is placed on live busbars Busbars can arise.
  • the contact pieces with the clamping screws and the connecting screws and the brackets are aligned on a common line perpendicular to the busbars in that the strip-like plastic adapter part is laterally limited by side walls which are on the top with the Plastic adapter part form a single, by means of a cover closable receiving space for the connecting lines, and that the side walls on the underside and / or the plastic adapter part are provided with projections which protrude on the sides thereof and the contact pieces facing away from the insertion sides of the clamps.
  • connection adapter Since all connection lines can be connected on a common line perpendicular to the busbars, the dimension of the connection adapter in the longitudinal direction of the busbar is limited to a connection width, so that the width of the connection adapter can be reduced to a third of the known connection adapter. As a result, more space for connecting other units is gained on a busbar system of a given length.
  • the plastic adapter part is divided into mounting blocks arranged one behind the other, which are integrally connected to the side walls, that a contact piece with the underside of each mounting block connected, preferably screwed, that each mounting block has two receptacles in the underside, which are accessible from the top of the plastic adapter part through holes, that the contact piece is inserted into both receptacles by bends, that in the one receptacle on the contact piece assigned clamp is held, the clamping screw is accessible through the bore of the receptacle, and that the contact piece in the other receptacle is designed as a connection contact with a threaded bore for the connection screw of the associated connection line, the connection screw being accessible through the bore of this receptacle. Therefore, only a small section of the contact pieces protrudes on the underside, specifically in the clamping area of the clamping ends of the clips which are held in the one receptacle by the angled contact piece.
  • connection of the connecting lines to the contact pieces is facilitated in one embodiment in that the connecting contacts of all contact pieces are arranged on one and the same side, preferably the insertion side, of the clips and lie outside the clamping area of these clips.
  • a further embodiment provides that the side of the following fastening block following the receptacle with a connecting contact of a contact piece of a fastening block is reduced in height to such an extent that this receptacle is open on the side and there is free access to the connection contact arranged in the receptacle with the connecting screw for connecting the connecting line.
  • connection contacts of the contact pieces are designed sloping towards the connection side of the respective mounting block.
  • At least the fastening block facing the insertion side of the connecting lines has a smaller height than the other fastening blocks.
  • the insertion of the connecting lines into the receiving space is facilitated in that the outward-extending insertion opening adjoins the fastening block facing the insertion side, which is formed by an inclined bottom wall and the two side walls.
  • a further embodiment provides that an L-shaped cover is used to cover the plastic adapter part, which covers the open top side with a cover plate and the narrow side of the plastic adapter part facing away from the insertion opening with a side leg.
  • a simple alignment of the cover to the plastic adapter part with its side walls is achieved in that two parallel guide webs are formed on the underside of the cover plate of the cover, the outer spacing of which corresponds to the inner distance of the two side walls in the region of the receiving space of the plastic adapter part.
  • a clear connection of the lid and plastic adapter part is obtained in that the guide webs at the free end of the cover plate have hook-shaped holding elements which are divided by recesses and which can be pushed behind retaining lugs formed on the inner sides of the side walls, and in that the side leg is on it inside has an integrally formed locking spring running parallel to the cover plate, which can be locked into a locking receptacle accessible from the underside of the plastic adapter part.
  • the latching receptacles are arranged in a shoulder of the facing fastening block and merges into an expanding release opening towards the top of the plastic adapter part and that the cover plate is attached to the detent spring is provided with a recess.
