Definitions
- the invention relates to a conductor connection with a U-shaped bracket and a screw unit that can be inserted from above into the bracket, onto the conductor inserted therein, consisting of screw, nut piece and wire protection part.
- a bearing pin and holder must be provided on the screw unit to pivot the screw unit and a corresponding receiving slot must be provided in the leg of the U-shaped bracket in order to pivot the screw unit into a position allowing the conductor to be put on from above and in combination to be able to move with it.
- the present invention has for its object to provide a conductor connection of the generic type, which ensures the insertion of the conductor to be connected from above with a simple construction of the conductor connection and with extremely convenient handling.
- the solution according to the invention consists in that at least one lateral projection is provided on the nut piece of the screwing unit on two mutually opposite sides and that at least one undercut receptacle accessible from above is provided in the U-legs of the U-shaped bracket. Thanks to this design, after inserting the conductor in the U-shaped bracket, which is still open at the top, the screw unit is placed in a movement essentially vertically from above, and the lateral projections on the nut piece can then be brought into the engaging position with the receptacle in the U-bracket.
- the required construction elements can have a simple spatial shape and are easy to manufacture.
- the locking means are arranged on the wire protection part surrounding the nut piece in a position such that the U-shaped bracket reaches the effective area by means of the nut piece when the screw is actuated in the conductor clamping direction.
- Locking is practically automatic when the screw is actuated. This also ensures that insertion is only possible with the screw open. If the screw is only turned slightly, the screw unit cannot be inserted or, above all, removed. When screwed in, the screw unit and the U-shaped bracket are therefore a captive system. This locks the overall clamping system. The locking also acts as a position fix when the clamping system is stressed by a conductor.
- the wire protection part is expediently designed as a barrel spring at the conductor connection, which, in addition to its functional advantages, also has the advantage of being easy to manufacture and easy to assemble, since it is sufficient to bend their two ends together which define the passage opening for the screw. Since in this case the barrel spring now has a function to perform in the locking, its positional stability and thus the positional stability of the locking must be ensured to a particular degree. It is therefore provided in a further preferred embodiment that the barrel spring has recesses on both sides in the region of its mutually bent ends, into which a U-shaped washer engages with its legs. As a result, the force of the legs of the barrel spring can no longer move inwards from their position in the direction of the screw shaft.
- a conductor connection is used in connection with a surrounding insulating material housing, as would be the case, for example, with a terminal block
- a pivot lever can then be provided on the insulating material housing, which is arranged so that when it is moved into its closed position, it moves the screw unit with the lateral projections on the nut piece into the engagement position with the U-shaped bracket.
- the conductor connection includes a U-shaped bracket 1, which is to be connected to a screw unit, which consists essentially of a screw 2, a nut piece 3 and a wire protection part 4, which is designed as a so-called barrel spring in the illustrated embodiment.
- the screw unit is assembled by bending the two free ends of the barrel spring 4, which define a passage opening for the screw 2 in their opposite position, in precisely this position.
- recesses 5 are provided on both sides of the barrel spring 4 in the region of their mutually facing free ends, into which a U-shaped washer 6 engages with its legs from above after assembly. Thanks to this configuration, the legs of the barrel spring 4 cannot twist or twist against one another. In this respect, they remain well-positioned.
- the screw unit described above can now be combined with the movement of the U-shaped bracket 1 essentially vertically from above. With the screwing unit removed, the conductor to be connected can first be inserted into the U-shaped bracket 1, which is still open to this extent.
- the nut piece 3 of the screwing unit now has two opposite sides at least one lateral projection 7a, in the exemplary embodiment shown also a further lateral projection 7b on each side.
- receptacles accessible from above are provided for receiving the projections 7a and 7b in the two bracket legs, specifically in the central region an undercut receiving opening 8a and open on the upper edge of the legs of the U-shaped bracket 1 further on one side a receptacle 8b opening to the side for receiving the projections 7b which, since here is the lateral end of the leg of the U-shaped bracket 1, can naturally also be moved vertically from above to the receptacles 8b.
- corresponding locking means are now provided on the wire protection part 4, that is to say here the barrel spring, in a very simple manner on one leg near its upper region has two laterally slightly projecting shoulders 9, which are arranged at such an altitude that when the screw 2 is completely turned into the open position (see FIG. 3), the screw unit with the lateral projections 7a, 7b on the nut piece 3 up to the undercut areas of the receptacles 7a, 7b can be spent in the U-shaped bracket 1 and the shifting according to FIG.
- a conductor connection as described above is implemented in a surrounding housing 10 made of insulating material. It can be a terminal block, for example.
- the U-shaped bracket 1 of the conductor connection then receives, for example, the end of the busbar 11 of the terminal block in its lower region.
- 10 guide slots 12, 13 are realized in the adjacent walls of the insulating material housing, into which the feeder leads lateral projections 7a, 7b of the nut piece 3 can occur.
- an angle lever 14 is mounted in such a way that immediately before reaching its closed position (FIG. 7) it acts on the side of the screw unit which is otherwise left free by the insulating housing 10 and when it is transferred to the complete closed position the aforementioned small shifting movement automatically causes.
