Definitions

  • the invention relates to a locking bracket of two housing parts, for electrical plug-in devices, which are formed on both housing parts in each case on side surfaces in pairs coaxially opposite and have the housing parts in pairs symmetrically opposite bearing journals, this locking bracket is U-shaped and has a handle part on its transverse legs is provided and its free U-legs each have an elongated hole that is open on one side for pivotable and displaceable mounting on one of the bearing journals of one housing part, an overlapping part with a snap-in recess for sliding on and engaging on one of the bearing journals of the other housing part, and at least one bow spring held on the free U-leg, which is tensioned when sliding on and, after latching in the locked state, exerts a force pulling the two housing parts together, w
  • the open end of the elongated hole is partially closed by a suspension fork that is open on one side.
  • the invention also relates to a housing part with two locking brackets of this type.
  • Such locking brackets are used in plug devices which consist of at least one plug and a socket part and are held together by a spring force generated by the locking bracket.
  • Locking brackets are known from the applicant, which have an inseparable riveted attachment to the plug or socket part.
  • the disadvantages of this embodiment lie in the inseparable fastening, by means of which a subsequent change in the stirrup belonging to the connector or Socket part is not possible and requires double storage, since both embodiments are required.
  • a lock of the type mentioned is known, in which the respective elongated holes receiving a pin are completely closed by a spring biased against the pin, and in which the locking bracket after attachment to the housing part only under greatest effort can be solved with a dedicated tool.
  • the invention has for its object to provide a locking bracket of the type mentioned, which creates an easily detachable connection between the locking bracket and plug or socket part at any time and thus allows any change between the two parts, as well as simplifying the necessary operations during assembly .
  • the object is achieved in that the suspension fork of the bow spring has a suspension fork opening which points in the direction of the open slot end, and the free opening cross section of the suspension fork opening in the relaxed state is smaller than the diameter of the bearing journal, the suspension fork partially enclosing the associated bearing bracket.
  • the snap lock enables quick and easy assembly of the locking bracket and, at the same time, a change between the plug and socket part of the plug device. If there is unfavorable space available when installing the plug device, the accessibility can be increased by changing the locking bracket between the plug and socket part, where the resilient snap lock from the bow spring is shaped as a spring fork open on one side and partially encloses the associated bearing journal. Due to the open suspension fork, the locking bracket can be attached to the bearing journal on the housing at any time and is spring-loaded when the U-shaped cold bracket slides over the dead center formed by the overlapping part onto the bearing journal located on the other housing section and with the recess this snaps into place.
  • the suspension fork which is formed in each case at the first bow spring end, is omega-shaped with a first short straight suspension fork end and a second elongated suspension fork end, which is returned via the arc of the omega-shaped suspension fork, and at the highest point continues straight and at least once angled into a second spring end.
  • the mechanical spring production can be simplified by the double-guided suspension fork, while the free end of the spring clip enables one-sided, spring-mounted attachment to the U-shaped locking bracket.
  • the bow spring with the second free bow spring end in the U-leg is held against rotation and captive.
  • a non-rotatable bracket for the bow spring ensures a secure, permanent function of the snap lock.
  • the second free bow spring end is angled in the plane of the open suspension fork and is fastened by at least two brackets which extend in opposite directions from the U-leg of the bow and overlap the bow spring.
  • the second free stirrup spring end is supported with respect to the stirrup by at least one bracket which extends from the U-leg of the stirrup and overlaps the stirrup spring and an angled hook part from the plane of the suspension fork.
  • This embodiment of the bow spring enables torsion-proof fastening with only one pronounced holder.
  • FIG. 1 shows a lower housing part 1 with a U-shaped locking bracket 2 and a bracket spring 3.
  • a U-shaped locking bracket 2 rests on the integrally formed bearing pin 5 in an elongated hole 7 which is open to the front on the free U-leg 6 and whose opening cross section 8 is partially closed by a resilient bow spring 3 .
  • the bow springs 3 are arranged on the inside and fastened with their hook-shaped bow spring end 9 in the oppositely shaped overlapping brackets 10, while the bow spring 3 with its omega-shaped suspension fork 11 partially encloses the bearing pin 5.
  • the suspension fork opening 12, which points in the direction of the open slot end 13, has an opening width 14 with a smaller distance than the pin diameter 15 of the bearing pin 5.
  • the locking bracket 2 held approximately on the center of the elongated hole 7 on the bearing pin 5 is an overlapping part 16 located on the U-leg 6 with a sliding surface 17 and a snap-in recess 23 for the bearing pins 5 opposite each other symmetrically to the connecting plane and one on the cross leg of the locking bracket 2 lying grip part 18 molded.
  • FIGS. 2 and 3 a lower housing part 1 is shown, with a housing upper part 19 resting on the elastic rubber seal 4 and a closed U-shaped locking bracket 2.
  • the locking bracket 2 encloses the bearing pin 5, which is formed coaxially opposite one another, with the one located on the U-leg Elongated hole 7 and the pair of symmetrically opposite bearing pins 5 'with the existing on the overlap 16 engaging recess 23, wherein the opening cross section 8 of the elongated hole 7 is partially closed by the spring fork 11 and exerts a spring force in the direction of the open slot end 13 when the U -shaped locking bracket 2 over the dead center, formed from the symmetrically opposite to the connecting plane bearing pin 5, slides away with the snap-in recess 23 onto the bearing pin 5 located on the other upper housing part 19.
  • FIG. 4 shows a bow spring 3 with an omega-shaped suspension fork 11, with a short rounded free suspension fork end 20, a second elongated suspension fork end 20 ', which continues in a straight line, led back over the arc 21 of the omega-shaped suspension fork 11, to the apex 22 of the suspension fork 11 and angled twice into a second bow spring end 9.
