Definitions

  • the invention relates to a connecting terminal with a receiving part with a threaded hole in a cross leg for a clamping screw and with a clamping bracket adjustable by means of the clamping screw relative to the receiving part, which is immovable with a side leg outside the cable receptacle of the receiving part, but is freely rotatable on the clamping screw and with the other side leg before the free end of the clamping screw is inserted into the cable receptacle of the receiving part.
  • a terminal of this type is known from DE-AS 23 31 760.
  • the cable is clamped between the side leg of the clamping bracket inserted into the cable receptacle and a wall of the U-shaped receptacle part.
  • the side leg of the clamping bracket is adjusted by the free end of the clamping screw against the cable and pressed against it.
  • the connection terminal is designed as a double terminal, the receiving part electrically connects the two connected cables to one another.
  • such a connection terminal is not suitable for connecting a cable to a busbar of a busbar system.
  • a terminal is known with which a cable can be connected to a busbar.
  • a closed pull frame is adjusted by means of a screw in a U-shaped pressure bracket.
  • the push bar encloses the open sides of the pull frame and forms the receptacle for the busbar and the cable with the part of the pull frame protruding from the pressure bracket.
  • the pressure bracket is supported on the busbar and the pull frame takes the cable with it when it is adjusted in the pressure bracket and braces it on the busbar.
  • This terminal must already be arranged on the busbar in order to be attached to it with the cable. The attachment of the terminal at any point on a laid busbar is only possible with considerable installation effort.
  • the receiving part is designed as a hook bracket
  • the cross leg carries the threaded bore for the clamping screw
  • the hook legs are provided with aligned receptacles for inserting a busbar that the side leg of the clamping bracket inserted into the cable receptacle of the hook bracket is enclosed by a bracket, the side legs of which run parallel to the hook legs of the hook bracket and are directed towards the open side of the hook bracket, that the clamping screw is guided through a hole in the cross arm of the bracket and that between the cross arm of the bracket and the cross arm of the hook bracket supports a coil spring attached to the clamping screw.
  • the hook bracket can be hung anywhere on a routed busbar, with the sprung one Bracket brings a provisional determination of the terminal on the busbar.
  • the bracket which projects with its side legs into the receptacles in the hook legs of the hook bracket, must be adjusted against the action of the coil spring when the busbar is inserted, so that the bracket exerts a tension force on the busbar.
  • the cable receptacle is formed, which is laterally delimited by the side legs of the mounting bracket supported on the busbar. This ensures that an stripped end of a stranded cable is fully gripped and jammed. No wires of the stranded cable can escape into the receptacles in the hook legs of the hook bracket, which take up play with play.
  • the connection of the cable is also facilitated by the fact that the connection terminal is already fixed on the busbar.
  • the immovable, but freely rotatable mounting of the clamping bracket on the clamping screw is obtained according to one embodiment in that the side leg of the clamping bracket between the screw head and a washer fixedly connected to the clamping screw is freely rotatable on a non-threaded portion.
  • the clamping bracket is inserted into the cable receptacle of the hook bracket from the same side as the receptacles for the busbar in the hook legs.
  • the cross leg of the clamping bracket is then turned away from the insertion side for connecting the cable.
  • a non-edged guidance of the bracket when adjusting in the hook bracket is achieved in that the clear internal dimension the hook leg of the hook bracket is matched to the outer dimensions of the side legs of the bracket.
  • good contact between the connecting terminal and the busbar is obtained in that the sides facing away from the clamping bracket are provided with teeth in the hook legs.
  • the fixing of the helical spring on the hook bracket is improved in that the cross leg of the hook bracket in the area of the threaded bore facing the retaining bracket carries a guide sleeve on which the helical spring is held.
  • the insertion and fixing of the cable end can be simplified and improved further in that the side leg of the clamping bracket that delimits the cable receptacle has a central longitudinal recess for the cable end.
  • connection terminal consists of the receiving part designed as a hook bracket 10.
  • the threaded bore 12 for the clamping screw 30 provided with the screw head 31 is made in the cross leg 11 of the hook bracket 10.
  • the two hook legs 14 and 16 are provided with the receptacles 15 and 17 for the busbar 33 arranged one on top of the other.
  • the sides of the receptacles 15 and 17 engaging behind the busbar 33 are provided with toothings 18 for good contact with the busbar 33.
  • the screwed into the threaded bore 12 clamping screw 30 carries outside of the hook bracket 10, the side leg 25 of the clamping bracket 24.
  • the side leg 25 of the clamping bracket 24 provided with a corresponding bore between the screw head 31 and the one firmly attached to the Clamping screw 30 connected disc 29 axially immovable, but kept freely rotatable.
  • the cross leg 27 of the clamping bracket 24 extends to the free end of the clamping screw 30 and is inserted with the other side leg 26 in front of the free end of the clamping screw 30 in the cable holder of the hook bracket 10.
  • the side leg 26 provided with the longitudinal indentation 28 (FIG. 4) forms a roof-shaped end wall of the cable receptacle.
  • the clamping bracket 24 is arranged with its cross leg 27 on the insertion side of the busbar 33, so that the side leg 26 is also inserted into the hook bracket 10 from this side.
  • the side leg 26 is enclosed by the holding bracket 20 so that the cross leg 21 of the same is above the side leg 26 of the clamping bracket 24.
  • the side legs 23 and 34 of the holding bracket 20 are aligned parallel to the hook legs 14 and 16 of the hook bracket 10 and directed towards the open side of the hook bracket 10. 4, the clear internal dimension of the hook legs 14 and 16 is matched to the outer dimension of the side legs 23 and 34 of the bracket 20, so that the bracket 20 is guided in the hook bracket 10 adjustable.
  • the bracket 20 extends across the width of the hook legs 14 and 16 and the side legs 23 and 34 widen on the insertion side of the busbar 33 to their free edges, so that the bracket 20 when inserting the busbar 33 into the receptacles 15 and 17 easily can be raised, as Fig. 2 shows.
  • the guide sleeve 13, onto which the coil spring 32 is pushed, is formed on the side of the cross arm 11 of the hook bracket 10 facing the holding bracket 20 in the region of the threaded bore 12.
  • the other end of the coil spring 32 is supported on the cross leg 21 of the bracket 20.
  • the clamping screw 30 protrudes through the bore 22 in the transverse leg 21 of the bracket 20 so that it can cooperate with the side leg 26 of the clamp bracket 24. If the busbar 33 is inserted into the receptacles 15 and 17 of the hook legs 14 and 16, the helical spring 32 presses the holding bracket 20 with the side legs 23 and 34 against the busbar 33, so that the cable receptacle is completed.
  • the side legs 23 and 34 laterally limit the cable receptacle, so that when the stripped end 36 of the stranded cable 35 is inserted and clamped, no wires can penetrate into the area of the receptacles 15 and 17, as can be seen from the view in FIG. 4.
  • the clamping bracket 24 can be adjusted with the clamping screw 30, the side leg 26 pressing the end 36 of the stranded cable 35 against the busbar 33.
  • the busbar 33 is then clamped in the receptacles 15 and 17 of the hook legs 14 and 16 of the hook bracket 10.
  • the clamping screw 30 is tightened, the holding bracket 20 already holds the connecting clamp on the busbar 33.
