Definitions

  • the invention relates to a plug coupling according to the preamble of claim 1.
  • the mating connector housing which penetrates the insertion opening of the wall is provided on its circumferential surface with a fine thread onto which a fastening nut can be screwed, between which and a flange of the mating connector housing the wall can be tensioned and thus the mating connector housing can be fastened to the wall.
  • the mating connector housing is assigned a union nut which can be screwed onto the threaded longitudinal region of the mating connector housing which projects beyond the fastening nut.
  • the connector housing can thus either be connected to or detached from the mating connector housing by screwing on or unscrewing the union nut, the mating connector housing remaining fixed on the wall in the latter case.
  • the assembly of at least the mating connector housing is lengthy because screwing the fastening nut onto the fine thread requires a lot of time and attention, not only because of the large screwing effort, but also because of screwing difficulties when the fastening nut is attached to the external thread of the mating connector housing.
  • the aforementioned disadvantages also apply to screwing on the union nut.
  • the invention has for its object to design a connector coupling of the type specified so that the connector housing and the mating connector housing with less manual attachment effort and in particular faster to be assembled with each other or on the wall.
  • connection between the fastening ring and the coupling ring and the mating connector housing is in each case a bayonet twist lock, which is easy and quick to put on and fasten the fastening ring or the coupling ring as well as a simultaneous tensioning of the wall between the fastening ring and the flange of the mating connector housing with little manual effort and time required.
  • the main parts of the plug coupling 1 of the electrical plug connection made of plastic molded parts are a plug housing 2 with a union nut 3 and a mating connector housing 4, to which a fastening nut 5 and an elastic sealing ring 6 are assigned.
  • the union nut 3 has at its rear end a radially inwardly projecting union flange 7, with which it engages behind a shoulder surface (not shown) on the connector housing 2.
  • the connector housing 2 protrudes to the rear out of the union nut 3.
  • the connector housing 2 and the mating connector housing 4 each have a plurality of chambers for receiving plug and mating connector contact elements, which are also plugged together in the plugged-in position of the plug coupling 1 according to FIG. 2.
  • the mating connector housing 4 has a contact flange 12 which projects radially from its cylindrical outer surface 11 in the rear region thereof.
  • the fastening nut 5 and the union nut 3 can each be fixed independently of one another by a bayonet lock 13, 14 in a specific fastening position on the mating connector housing 4.
  • the bayonet lock 13 for the mounting nut 5 is in the first, the contact flange 12 front end of the mating connector housing 4 arranged adjacent longitudinal region 15.
  • the bayonet lock 14 for the union nut 3 is arranged in a second longitudinal region 16 on the lateral surface 11 of the mating connector housing 4, which extends from the first longitudinal region 15 to the front, preferably to the front end of the mating connector housing 4.
  • the bayonet lock 13 for the fastening nut 5 is of the same size and shape as the bayonet lock 14 for the union nut 3, and it represents a second stage of the bayonet lock 14 for the union nut 3. That is, the fastening nut 5 is through or over the bayonet lock 14 for the union nut 3 can also be pushed into the area of the associated bayonet lock 13.
  • Each bayonet twist lock 13, 14 is assigned a locking recess 17, 18 in the respective fastening position of the fastening nut 5 or the union nut 3, into which the associated closure element engages on the fastening nut 5 or union nut 3 in the fastening position, so that an automatic turning back and loosening the bayonet locks 13, 14 is prevented.
  • the bayonet locks 13, 14 are formed by a three-start thread with three thread grooves 19a, 19b, 19c arranged uniformly distributed in the circumferential direction on the circumference of the cylindrical connector housing 2, which run out at its front end and thus form inlet openings 21a, 21b, 21c.
  • From the inner circumferential surfaces of the fastening nut 5 and union nut 3 project radially inward three cylindrical pins arranged uniformly distributed over the circumference, which are integrally formed on the associated inner circumferential wall 20 and whose diameter and length are adapted to the width and depth of the thread grooves 19 that the pin can be moved with little play.
  • Fig. 1 only one pin 22 of the three existing pins of the fastening nut 5 is shown.
  • the turning effort for the fastening nut 5 is somewhat larger, but also relatively small, preferably additionally about a quarter to a half turn, due to the spacing in the circumferential direction the locking recesses 17, 18 can be seen from FIG. 1. Due to the large pitch of the thread grooves 19a, 19b, 19c, the attachment is not self-locking. Securing against unintentional turning back or loosening takes place by means of the rounded locking recesses 17, 18.
  • recess grooves 23 are provided for the purpose of saving material and weight for the mating connector housing 4 in its cylindrical lateral surface 11, which results in thread-like webs 24 on both sides of the thread grooves 19a, 19b.
  • the recess grooves 23 do not run out at the front end of the mating connector housing 4, since they are closed here by connecting webs 25 which extend in the circumferential direction and connect the mutually adjacent webs 24, so that only the inlet openings 21 are located at the front end of the mating connector housing 4 incorrect screwing of the pin 22 is prevented.
  • the mating connector housing 4 is inserted from the right into a round hole 27 of a size adapted to the diameter of the mating connector housing 4 to such an extent that the contact flange 12 on the wall 26 is present. Then the elastic sealing ring 6 from the other Pushed on the mating connector housing 4. It is also possible to arrange the sealing ring 6 between the contact flange 12 and the wall 26. Then the fastening nut 5 is screwed into its fastening position, in which the elastic sealing ring 6 is somewhat compressed.
  • the sealing ring 6 thus represents a spring element 30 which seeks to spread the plug connection and thus presses the pin 22 into the locking recesses 17, 18, from which they can only be pushed out with a certain reversing force. This prevents unintentional loosening of the fastening nut 5.
  • an elastic sealing ring (not shown) comparable with the elastic sealing ring 6 (not shown) can be provided between the coupling flange 7 of the coupling nut 3 and the shoulder surface already mentioned on the plug housing 2 or between the mutually facing surfaces of the coupling nut 3 and the fastening nut 5.
  • spring elements 30 of a different design and arrangement are also possible within the scope of the invention.
  • a spring element 30 can, for example, also be formed by an elastic layer (not shown), which is arranged on one of the axially active contact or clamping surfaces. Since the connector housing 2, the union nut 3, the mating connector housing 4 and the fastening nut 5 are plastic injection molded parts, it is possible and also advantageous to foam or foam an elastic layer on at least one of the abovementioned contact surfaces or to foam a sealing ring 6, and although preferably on the contact flange 12 and / or the surface of the fastening nut 5 facing the union nut 3.
  • the spring elements 30 which are integrally formed on the union nut 3 and / or the fastening nut 5.
  • the spring elements 30 are formed by bridge webs 32 which preferably extend in the circumferential direction and which bridge a cutout 33, are formed on one of their two ends (FIG. 6) or on both ends (FIG. 5) and are thus transverse to themselves , ie can be bent axially to the component carrying them (union nut 3, fastening nut 5) and, due to their elasticity, spring back automatically into their starting position.
  • the bridge webs 32 On their side facing away from the cutout 33, the bridge webs 32 — viewed radially — are rounded or roof-shaped with inclined surfaces 34, 35, whereby a spring cam 36 is formed.
  • the arrangement is such that, in the fastening position of the union nut 3 and / or the fastening nut 5, the associated spring cam 36 is prestressed in the direction of the longitudinal central axis 31 against the fastening nut 5 or the wall 26 and thus generates an axial prestress which the pins 22 the union nut 3 and the fastening nut 5 presses into the locking recesses 17, 18. This also prevents unintentional loosening of the respective bayonet catch 13, 14.
  • a spring element 30 in the form of a bridge web 32 is arranged on the side surface of the union nut 3 facing the fastening nut 5, the associated spring cam 36 originally projecting from this side surface.
  • the associated cutout 33 traverses the hollow cylindrical wall of the union nut 3 radially.
  • a spring element 30 can also be provided on the side surface of the fastening nut 5 facing the union nut 3, as is shown in FIG. 4.
  • the union nut 3 and the fastening nut 5 have axial grooves and / or grooves on their outer circumferential surfaces in order to enable the manual attack for the purpose of closing or loosening the bayonet catch or the attachment of a turning tool.
