Definitions

  • the present invention relates to a tension and pressure relief means for a connector housing.
  • all plug connectors have a strain relief means for a cable which is electrically connected to the plug connector.
  • the respective strain relief means can be designed very differently.
  • the strain relief means is formed, for example, by a bracket over a cable support element, between which the cable is clamped, the cable support element being connected to the connector housing.
  • the bracket is pressed or pulled against the cable support element with one or two screws.
  • WO2014 / 076269A1 discloses a strain relief means which is formed by conical knobs or prongs in a cable duct, which are fixedly arranged in an interior of the cable duct and are oriented into the cable duct.
  • the cable duct comprises two housing parts or housing halves, which can be opened laterally relative to one another to form a longitudinal axis of the cable duct, in order to be able to insert and close the cable therein.
  • the knobs or prongs are pressed into the cable or into a cable sheath of the cable.
  • the two housing parts can be pressed onto one another or into one another in stages by means of a latching mechanism. Tolerances in a cable diameter can be compensated for in notch steps.
  • EP2359441 B1 discloses a strain relief means which is formed by a contour in the cable duct of the connector housing, the cable duct comprising two housing parts which can be opened to each other laterally to the longitudinal axis of the cable duct so that the cable can be inserted and closed therein. At least one of the housing parts is conductive in order to contact a shielding conductor of the cable that is exposed in the area of the strain relief. As the two housing parts with the cable with the exposed shield conductor in between are pressed together and closed, the contour of the housing parts is pressed into the shield conductor and clamps and makes contact with the cable at the same time. However, a tolerance of the cable diameter can hardly be compensated for.
  • DE102011052199B3 discloses a strain relief means which is formed in a band-like spiral around the cable duct axis with inwardly projecting prongs
  • the Cable duct comprises two housing parts which can be folded open to each other laterally to the cable duct longitudinal axis in order to be able to insert and close the cable therein.
  • the two housing parts In a rear section, the two housing parts each have a thread half on the outside, so that when folded together they form the thread onto which an end cap with a mating thread can be screwed.
  • the knobs or prongs are pressed into the cable sheath of the cable and lock it in place with the connector housing.
  • the two housing parts are locked to one another by the end cap by screwing it onto the rear sections of the housing parts.
  • the strain relief means can also contact the shield conductor of the cable.
  • the tolerance of the cable diameter is only compensated to a limited extent. It would also be advantageous if the cable were also kept in its position secured against compressive forces.
  • WO2008071917A1 discloses an essentially two-part connector housing with a leaf spring element as the tension and pressure relief means for the cable, the tension and pressure relief means being formed by serrated clamping elements which are integrated in two opposite cover parts and protrude therefrom towards the cable duct and essentially transversely to the cable duct longitudinal axis are arranged.
  • DE102016004429A1 discloses a multi-part connector housing with a leaf spring element as the tension and pressure relief means for the cable, the tension and pressure relief means being designed as a substantially annular spring element around the cable, in a plugged-together state of the connector housing pressed into the cable and thereby in the connector housing is held.

  • the object of the invention in order to eliminate the disadvantages from the prior art, is therefore to provide a plug connector with a tension and pressure relief means for a cable, which enables the most reliable possible strain relief for the cable, also taking into account a tolerance of a cable diameter, whereby the strain relief should also be carried out using as few separate parts as possible and as inexpensively as possible.

  • the central part extends between the first and the second bending edge along a central part longitudinal axis, the first and the second bending edge each being perpendicular to the central part longitudinal axis, and the central part longitudinal axis lying essentially in a common plane with the cable duct longitudinal axis.
  • the first side part can assume a variable acute first angle and the second side part a variable acute second angle towards the middle part, and a first end section of the first side part, which is opposite the first bending edge, has a variable first height and a second end section towards the middle part of the second side part, which is opposite the second bending edge, assume a variable second height towards the middle part.
