Definitions

  • the present invention relates to an electrical installation device, such as a switch, a button, a socket or the like, with a base part on which one Device for strain relief arranged for a connectable electrical line is.
  • Installation devices with devices for strain relief for connectable electrical Lines are known.
  • a known device for strain relief for example, from a cover web, which with the base part, such as the bottom, one Wall, a housing part or the like, is screwed by the line overlaps transversely to its longitudinal direction.
  • the presence of a screw connection requires for the assembly of the Strain relief device when connecting a line in the simplest case Screwdriver.
  • a screw is a lightweight lost part, and the assembly process requires, e.g. when applying the Screw, some accuracy and time.
  • the present invention has for its object an electrical Improve installation device of the known type so that with simplification and Shortening the assembly process when connecting a line an effective Strain relief is guaranteed.
  • the device for strain relief by at least two spaced apart, connected to the base part, in essentially rigid, based on a longitudinal direction of the assembled line Clamping elements arranged on one side and at least one with the base part connected, essentially resilient, based on the longitudinal direction the line arranged on the other side clamping element is formed.
  • the electrical installation device ensures an effective Strain relief by the electrical line, preferably near one to the Connection of a certain end between the rigid clamping elements on one side and the resilient clamping element can be clamped on the other side.
  • an effective Strain relief by the electrical line preferably near one to the Connection of a certain end between the rigid clamping elements on one side and the resilient clamping element can be clamped on the other side.
  • the two Figures 1 and 3 show an electrical installation device according to the invention with a base part 1, on which two (unspecified) devices for Strain relief for a connectable electrical line 2 (Fig. 3), e.g. a NYM cable, are arranged.
  • the base part 1 can be act a base, a floor, a wall, a housing part or the like.
  • the two illustrated devices for strain relief are of the same design and differ only in their size, which are different Line diameter D is matched.
  • the devices for strain relief are each in accordance with the invention at least two spaced apart by a distance A (Fig. 2), with the Base part 1 connected, essentially rigid, based on a longitudinal direction X-X of the assembled line 2 clamping elements arranged on one side 3, 4 and at least one, connected to the base part 1, essentially resilient, based on the longitudinal direction X-X of the line 2 on the other side arranged clamping element 5 is formed.
  • the resilient clamping element 5 is the distance A of the two rigid clamping elements 3, 4 arranged approximately in the middle, so that one in the Strain relief device located line 2, in particular symmetrical acting three-point load, the two rigid clamping elements 3, 4 form a counter bearing for the resilient clamping element 5.
  • On at least one clamping element, preferably on all clamping elements 3, 4, 5 can - as shown - for a fixed mounting of the line 2 in the direction of the line 2 facing (unspecified) cutting edges. Around To prevent damage to the cable sheathing, these cutting edges to be blunted with advantage.
  • the clamping elements 3, 4, 5 are in one piece in a manner advantageous in terms of production technology executed with the base part 1 and as perpendicular from a surface 1 a of the base part 1 protruding webs formed.
  • the electrical device according to the invention can be used Installation device a connectable to the base part 1, in particular latchable, Cover part 6 may be provided which, in the closed state, the clamping elements 3, 4, 5 overlaps and covers.
  • the cover part 6 is one-sided captively connected to the base part 1 via a film hinge 7 and points on the other hand in an edge web 8 located locking openings 9, 10, which for Closing the cover part 6 with corresponding locking hooks 11, 12 on Interact base part 1.
  • the cover part 6 has at least one projection 13 on its underside 6a when the cover part 6 is closed in a substantially perpendicular to the surface 1a of the base part 1 acting direction between the clamping elements 3, 4, 5th held line 2 presses. In this way, the line 2 is in the assembled state All-round advantage - on the one hand between the clamping elements 3, 4, 5, on the other hand between the surface 1a of the base part 1 and the projection 13 on the cover part 6 - held.
  • the above mentioned cutting of the clamping elements 3, 4, 5 is preferably asymmetrical be, a first side surface S1 tapering toward a cutting edge K being preferred is oriented approximately perpendicular to the longitudinal direction X-X of the line 2 and a second side surface S2 running towards the cutting edge K with the first Side surface S1 forms an acute angle.
  • the invention is not limited to the exemplary embodiment described, but rather also includes all designs having the same effect in the sense of the invention. So can for example, more than the clamping elements 3, 4, 5 shown e.g. three or five rigid clamping elements and two or four resilient ones Clamping elements, which then again - as shown in the exemplary embodiment - interlock like a zipper. This can increase the tensile strength of the Strain relief device to be increased.
  • the first side surface S1 can (deviating from that shown at right angles Course to the longitudinal direction X-X of the line 2) also run in one plane, which forms an acute angle with the longitudinal direction X-X of line 2, which is open towards the connection point 14 for line 2 and larger is than the angle that the second side surface S2 has with the longitudinal direction X-X the line 2 includes.
  • the person skilled in the art can use the electrical installation device according to the invention supplement with additional appropriate technical measures without the Is left within the scope of the invention.
  • the spring-elastic clamping element 5 also by means of an additional, transverse to the longitudinal direction of the line 2 acting compression spring loaded so that despite a possible retreat of the Line 2 opposite the clamping element 5, for example due to signs of aging (Flow processes) of a cable sheath, permanently secure mounting of the Line is guaranteed in the strain relief device.
  • the invention is not based on the combination of features defined in claim 1 limited, but can also be by any other combination of certain features of all of the individual features disclosed are defined. This means that basically every single feature of claim 1 omitted or by at least one disclosed elsewhere in the application Single feature can be replaced. In this respect, claim 1 is only a first To understand the attempt to formulate an invention.
