  • a such strain relief device can be arranged very space-saving on the one hand on the other hand, it allows a comparatively simple and short Assembly process 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. When the line is inserted between the clamping elements, the resilient gives way Slightly back clamping element and then hugs again to the electrical line. The use of screws can be avoided become.
  • connection point (s) it is advantageous if one with a Single device bottom part connectable cover part is provided, which in closed state, the connection point (s) and, if applicable, the device (s) overlaps and covers for strain relief.
  • Such a cover part can be attached to the individual device in an advantageous manner in particular, be connected on one side to the housing base via a film hinge and have locking elements on the other side, which when closed with corresponding Interact locking elements on the single device.
  • the installation device in particular a triple socket that can be inserted is determined in a cable duct, not shown.
  • the installation device consists of three single sockets 2, 3, 4 and arranged side by side in a housing 1 has two connection points 5, 6 for connecting electrical lines, of which a line 7, e.g. a three-core NYM cable is shown as an example.
  • the Connection points 5, 6 are designed in the form of wire terminals, to the two Cables can be connected, the number of terminal points (in shown case there are six) is matched to the number of wires of the lines 7.
  • connection points 5, 6 are arranged below a bottom 1a of the housing 1 in such a way that a connected electrical line 7 each essentially parallel to a longitudinal axis running through the housing 1 Y-Y (Fig. 2) is.
  • either at least two in a wire clamp side by side lying electrical lines 7 may be electrically contacted and / or it must have an electrically conductive connection through the housing 1 through the a junction 5 to the opposite junction 6 may be present.
  • connection points 5, 6 for the electrical lines are in one bottom edge area of the two outer individual sockets 2, 4 arranged, which adjoins the individual socket 3 arranged next to it (in the middle).
  • the devices for strain relief are each by at least two a distance A from each other (Fig. 3), with the bottom 1a of the housing 1 connected, essentially rigid, based on a longitudinal direction X-X mounted electrical line 7 clamping elements 8, 9 arranged on one side and at least one, essentially spring-elastic, connected to the bottom 1a, based on the longitudinal direction X-X of line 7 on the other side arranged clamping element 10 formed.
  • the advantage of such Strain relief device includes in being a screwless assembly allowed.
  • the spring-elastic clamping element 10 is the distance A of the two rigid clamping elements 8, 9 arranged approximately in the middle, so that in the Strain relief device located cable 7 in particular symmetrical exposed to three-point load, the two rigid Clamping elements 8, 9 form a counter bearing for the resilient clamping element 10.
  • On at least one clamping element, preferably on all clamping elements 8, 9, 10 can - as shown - for a fixed mounting of the electrical line 7 in the direction of the line 7 facing (not specified) cutting edges his. To prevent damage to the cable sheathing, this can Cutting should be blunted with advantage.
