Definitions

  • the invention relates to a screwless clamp according to Preamble of claim 1; such a clamp is known from JP06215810.
  • a screwless clamp is known from EP 0 052 767 A1, whose clamping spring can be released by a tension plunger or can be connected to a busbar.
  • Such screwless clamps are also called cage clamps or as a "cage clamp".
  • a cage clamp is generally with a suitable object, for example a screwdriver, directly the live one Clamp spring depressed.
  • an insulated tool is required to get out of a screwless one Clamp a connected conductor again can.
  • each wire in a line is in its own Connection process clamped and if necessary also released again.
  • Actuate especially open, a screwless clamp for several electrically isolated wires at the same time, comb-shaped insert parts are already provided Service. However, it is necessary that the actuation side is widely accessible.
  • the invention has for its object a simple and screwless clamp of the aforementioned type which can be handled safely Kind of develop.
  • a screwless clamp according to claim 1.
  • a release pressure piece in the release direction of the Clamping spring a sliding wedge-shaped release body in operative connection. On the clamping spring this is done by a resting one Part of the pressure exerted so that the clamping spring can tilt excluded are.
  • the solver can be done in easier Manufacture way from insulating material, so security is guaranteed.
  • a release pressure piece can be good Sliding property must be selected.
  • the sliding solenoid can or the release pressure piece as wedges that can be moved against each other be executed.
  • the sliding solenoid can or the release pressure piece as wedges that can be moved against each other be executed.
  • a partition for the connection opening can be the associated terminal in this way stand that the connection opening without a connected conductor is largely or completely closed.
  • the screwless clamp according to FIG 1 has three rows Clamping springs 1, each having a conductor to be connected 2 under spring force with a busbar 3, vertically to the drawing level. Compare also FIG 2. With the clamping spring 1 or with a release pressure piece 4 there is a sliding wedge-shaped release body in the release direction 5 in operative connection. For three adjacent clamping springs 1 the wedge-shaped release body 5 and the associated release pressure piece 4 the formation of a sawtooth.
  • the sliding one Release body 5 and an associated release pressure piece 4 are designed as two wedges that can be moved against each other each have the formation of a sawtooth.
  • the solver 5 can be actuated from the side by a plunger 6 become.
  • FIG. 2 clearly shows how spreading is carried out of release body 5 and of release pressure piece 4 a clamping spring 1 depressed in position 15 in the delicately drawn Position. Compare the figures corresponding to FIGS. 1 and 2 3 and 4 for the clamping springs 1 in their depressed Position.
  • the loop-shaped clamping spring 1 in which one leg 7 through a window 9 of the other Leg 8 is inserted, this window 9 is under pressure through the release body and the release pressure piece with its lower Edge released in leg 8. You can then become a leader 2 pull off or insert gently.
  • the according to FIG 2 and 4 lower edge 10 can generally be used as the outer edge of the Window 9 are called.
  • the windows 9 are at reproduced not introduced head, being descriptive because of the opening of the window 9 in the clamping spring is shown how an introduced conductor can stop it would.
  • the release body 5 and the release pressure piece 4 according to FIG. 5 are in the End area of their spreading displacement with a Flattened 11 provided, causing clamps in their open position can be held in the position according to FIG. 6, without the wedge-shaped surfaces under the force of the clamping springs can slide back.
  • solids 5 and loose pressure piece 4 in the end region of its spreading displacement distance be designed to be a latching Achieve open position of the clamp until the plunger 6 again is operated.
  • the partition part in the embodiment according to FIG 7 and in side view 8 according to FIG. 8 is a partition part with the release body 5 12 for the connection opening 13 of the associated Terminal in connection.
  • the partition part can 12 when moving perpendicular to the plane of the drawing 8 shows the connection opening 13 with an inserted conductor 2 largely close and without inserted conductor be moved so far that the connection opening 13 is closed is. Understandably, it is recommended to use the foreclosure part to be made from insulating material.
  • the partitioning parts can advantageously be be resiliently connected for the release body.
  • a screwless clamp of the type described has, inter alia, the following advantages:
  • the actuation of the terminal can be operated from the front in a row of housings with a multi-level terminal arrangement, as is usual with terminal blocks. There is no need for increased space for aids for actuating the clamping spring, so no access must be kept free for a release operation. Short assembly times can be achieved with adjacent terminals by operating several terminals at the same time.
  • the clamping springs can be completely insulated with regard to the actuation side and there is no need to isolate an aid since this is not required anyway. If necessary, the clamp can simply be designed in such a way that stable opening is achieved. The clamped state can easily be made visible by the position of the release body or by the position of a plunger.
