Definitions

  • the present invention relates to a plug assembly having a first plug element and a complementary second plug element for making an electrical connection, wherein each of the plug elements comprises a plug housing with a plug contact end and a cable insertion end opposite thereto, and wherein the plug elements have complementary bayonet fitting components to the plug contact ends, which are to be brought together to form a the plug-in elements in the assembled state securing BejonettverBankes.
  • Such plug assemblies are used, for example, for the wiring of lighting equipment in film and television.
  • such connector assemblies are subject to high loads and there is a risk due to acting on the connected cables tensile forces that solve the cables or wires of these cables from the connector or that break individual wires in the cable due to mechanical action at the cable entry end of the connector elements.
  • the object of the invention is to provide a generic connector assembly, which allows improved handling.
  • the strain relief device comprises the cable receiving opening defining ring sections, which can be fastened to one another by exerting a radial clamping force on a cable inserted into the plug element through the cable receiving opening.
  • Such a connector assembly has the advantage over the previously known connector assemblies that the strain relief device for the connected cable is integrated into the connector housing, so that it is not mounted as a protruding component on the connector assembly. Furthermore, the strain relief device acts due to the force acting on the cable radial clamping forces and due to the integration in the connector housing also sealing against contamination and moisture. In this case, the radial clamping forces act on the sheathing or insulation of the inserted cable such that this sheath rests like a kind of sealing ring on the ring sections.
  • At least one of the ring sections is formed integrally with the respective connector housing.
  • This ring portion forms a kind of base to which the other, the cable receiving opening defining ring portions can be attached, so that all ring sections together define the cable receiving opening and fully assembled form part of the plug housing, namely preferably an outer visible Steckergephaseuseende the cable entry end, preferably free of sharp edges on the outside surface.
  • the ring portions may each have at least one radially inwardly extending and circumferentially extending projection.
  • This projection may be formed, for example in the form of a semicircular clamping bead, so that the sheath of the cable is not damaged in the clamped state.
  • the plug arrangement has two ring sections. These ring sections can each form approximately a semicircle around the cable receiving opening to be defined.
  • one of the ring sections has one projection more than the other ring section, wherein it is particularly proposed that the projections of the two ring sections are arranged offset in the axial direction relative to one another in the assembled state , In the case of the two ring sections, the cable is then radially clamped between at least three projections, wherein two of these projections are formed on the one ring portion and the third projection is formed on the other ring portion.
  • the ring portions are screwed or screwed together by means of screws, wherein it is particularly preferred that the screws are recessed in the assembled state of the ring portions in openings.
  • the ring sections are formed in the region of the cable entry end such that the cable receiving opening is widened like a funnel in the plug housing of the respective plug element. Such a widening makes it possible for the cable to bend in the region of the receiving opening and to lay flat against the annular sections, thereby preventing kinking, such as edge receiving cable receiving openings.
  • the funnel-shaped widening is preferably formed by an outwardly curved course of the inner circumference of the ring sections. This leads to a trumpet-like configuration of the cable receiving opening, which allows the planar contact of the same on the ring section even with a cable which is bent very strongly relative to the plug arrangement.
  • the cable receiving opening merges with a continuously curved course in the frontal cable entry end of the relevant connector element.
  • the cable entry end thus has no edges at which a violation of the sheath of the cable or a mechanical action on lying in the sheath wires of the cable can be done.
  • the risk of cable breakage in the region of the cable receiving opening or the cable insertion end of the plug assembly is greatly reduced.
  • the plug elements comprise a seal which adjoins the ring sections axially in the direction of the plug contact end, the seal being integrated in the respective plug housing.
  • a ground is provided, which is preferably realized using a ground ring, which is arranged in a seat on the inner circumference of the plug housing and is in electrical contact with this.
  • the grounding ring may comprise a grounding wire affixed thereto, preferably soldered or welded, the grounding wire being connectable or connected to a grounding conductor of the connected cable.
  • the grounding ring is made of brass and the grounding wire is made of copper.
  • the two connector elements 12, 14 have a respective cable entry end 26, 26 'into which a respective cable 28, 28' is inserted.
  • a strain relief device is integrated in the region of the respective cable entry end 26, 26', which will be described in more detail below.
  • the Fig. 2a and b each show the first connector element 12 and the second connector element 14 in a schematic plan view.
  • the Fig. 2c and d show cross-sectional views of the first connector element 12 according to the line CC of Fig. 2a and a cross-sectional view of the second plug member 14 corresponding to the section line DD of Fig. 2b ,
  • the above-mentioned strain relief device 32 will be described below with reference to FIGS Fig. 2c . 3, 4 and 5 for the first plug element 12, wherein the second connector element 14 comprises an identically designed and identically acting strain relief device 32 '.
  • the strain relief device 32 comprises two ring sections 34, 36, wherein the one ring section 36 is formed integrally with the housing 30 of the plug.
  • the two ring sections 34, 36 have a semicircular shape and abut against each other at bearing surfaces 38.
  • the two ring sections 34, 36 are fastened to each other by two screws 40, so that the plug housing 30, on which the one ring section 36 is integrally formed, is completed by the screwed-on ring section 34.
  • the plug housing 30 thus also includes the releasably secured ring portion 34.
  • a cable can be passed through the cable receiving opening 42 and electrically connected to corresponding plug contact components (not shown) in the respective plug element.
  • the loose ring portion 34 can be screwed to the ring portion 36, wherein radial clamping forces are exerted on the inserted cable by projections 44a, 44b and 44c, so that this is not from the respective plug member 12, 14 and Plug assembly 10 can be pulled out.
  • the projections 44a and 44c are arranged on the loose ring portion 34 at a distance A from each other.
  • the projection 44b on the annular portion 36 integrally formed with the housing 30 is located in the axial direction between and against the projections 44a and 44c, so that the projections 44a, 44b and 44c are offset from each other in the axial direction.
  • This staggered arrangement results in a very good clamping effect on the inserted cable and on the other hand allows the contact between the projections 44a, 44b and 44c and a sheath 46 ( Fig. 6 ) of the cable 28, a seal of the interior 48, 48 'of the respective plug member 12, 14.
  • the cable receiving opening 42 is widened like a funnel, this widening being formed by an outwardly curved course of the inner circumference 50 of FIG Ring sections 34, 36 is formed.
  • the cable receiving opening 42 is thus formed trumpet-like and has no edges that could lead to a cable break in the cable 28. If the cable 28 is deformed or bent in the region of the cable receiving opening 42, it lies flat against the inner circumference 50 of the ring sections 34, 36, and there are no strong points force on the sheath 46 of the cable 28, as in edged housing forms the Case is. Thus, even a bending of the cable 28 by more than 90 ° does not lead to excessive stresses on the cable 28, the inner circumference 50 goes over with a continuous curved course in the end-side cable entry end 52 of the relevant connector element 12, 14.
  • the screws 40 are recessed in openings 54 of the ring portion 34 so that they do not project beyond the substantially circular and smooth outer contour 56 of the plug housing 30.
  • the risk of injury to an operator is reduced and a snagging of the respective plug member 12, 14 with other lying in the vicinity of the plug assembly things, such as other cables, cords, outside lying around branches and the like., Is excluded.
  • the round shape of the plug assembly 10 with integrated sealing strain relief 32 on the outer contour 56, 56 'protruding components so that the handling of the plug assembly is improved and the risk of injury to operators is reduced.
  • a grounding ring 58 is received, which is connected via a grounding wire 60, which is preferably soldered or welded to it, with a grounding conductor de cable 28, 28 '.
  • the grounding ring 58, 58 ' is received with a ring seat 64, 64' formed on the inner periphery 62, 62 'of the plug housing 30, 30' and is in electrically conductive contact with the housing 30, 30 '. Due to the used conductive and ROHS-compliant surface of the housing 30, 30 'and the positioning of the grounding ring 58, 58' between the housings 30, 30 ', the complete housing 30, 30' is conductive. It is particularly advantageous that a good conductivity over the entire connector length, ie between the front part 30 and the rear part 30 'of the housing is made possible.
  • the plug elements 12, 14 axially following the ring sections 34, 36, 34', 36 'an annular groove 70 for receiving a sealing ring (not shown ), so that a seal of the inner space 48, 48 'even with decreasing radial clamping action of the projections 44a - c is ensured.
  • the bayonet closure comprises an insertion aid, which is formed by a radially inwardly projecting pin 66 on the second connector element 14 and an opening formed on the first connector element 12 axially extending opening 68.
  • This insertion allows the mating of the two connector elements 12, 14 in only one relative position to each other, so that the correct mating of the two connector elements 12, 14 is ensured.
