Definitions

  • the invention relates to a connector for lights such as, in particular, spotlights, consisting essentially of two connector parts each containing a contact set, a pin-like male part and an essentially shape-corresponding sleeve-shaped female part, one of which is to be attached to the light console and the other to the supporting part, such as a support tube or cable of a light head is, the connector parts are designed for a releasable plug-in coupling with anti-rotation.
  • the lamp bracket can be designed as a wall or ceiling outlet, also with a built-in transformer, while the lamp head carrying the lamp is arranged on a tube to be connected to the lamp console, through which the lines for supplying voltage to the lamp are passed.
  • the main advantages of a luminaire in which the luminaire head and luminaire console are connected to one another by a separable plug connection apart from the possibility of universal single-part production, are the fact that luminaires can be variably installed and also implemented. If you provide a variety of luminaire brackets, luminaire heads of the desired type, shape and color can be connected to them if required, with a different location. This flexibility is of enormous importance, especially for shop and shop window lighting.
  • the lamp for example a ceiling light, can be replaced more easily by removing the lamp head from the lamp console. Understandably, it is important that the plug-in connection is easy to handle and safe in terms of both electrical and mechanical function.
  • a known connector of the type presupposed in the preamble of claim 1 consists of a matrix-like connector part to be fastened to the lamp console and a male-like connector part which is fixed to the diameter of the support part and is arranged on the latter.
  • This consists of a metallic rotating part with coaxially arranged ring contacts that are insulated from each other by means of plastic, the rotating part also having milled surfaces for non-rotatable reception in the mating connector part and an annular groove.
  • This annular groove is used for locking in a special sleeve assigned to the die part, which contains a spring clip wire to be locked with the peripheral groove of the plug part, which can be moved by axial displacement of the sleeve in the release position of the locking connection.
  • the male connector part of the connector is very complex in terms of manufacture and assembly.
  • the invention is essentially based on the object of providing a connector of the type mentioned above, which is considerably improved with a simple structure in terms of problem-free and simple handling.
  • both connector parts each have an insulating body carrying the relevant contact set
  • the die part has at least one circumferential recess
  • the male part has a corresponding latching hook, which is integral and material-uniform on the insulating body of the male part is integrally formed and can be actuated by means of a push button against a force of a spring acting on it in the latching position with the peripheral recess of the die part.
  • the latching hook is arranged on a material section of the male part which forms a leaf spring and is cut free from the insulating material body. If the insulating material body is designed in the form of a sleeve in this area, the leaf spring and latching hook can be produced by simple longitudinal incisions in the sleeve wall, and it is possible to compress the interior of the sleeve in a favorable manner.
  • the contact adjoining the sleeve section for plugging onto the end of the supporting part Carrier section is preferably flat rectangular in cross section and carries a large-area contact on its two main surfaces, the width of the two main surfaces of the contact carrier section being substantially equal to the diameter of the sleeve section.
  • the rectangular design of the connector part in the contact area can also fulfill the function of an anti-rotation device in the contact area of the contact sets of the connector parts.
  • An alternative or additional, as well as increased anti-rotation, effect can be achieved in that at least one flattened portion is arranged on the jacket of the sleeve section of the male part and a corresponding, non-rotating stop surface is arranged in the cavity of the female part.
  • the stop surface extends to the mouth of the die part and the corners and edges of the contact carrier section are chamfered and / or rounded.
  • the main surfaces of the contact carrier section can merge into the sleeve section via guide bevels and the contacts of the die part can have funnel-like centering sections acting on the contact carrier section of the male part, which reach at least approximately up to the wall of the cavity of the die part.
  • the inclination of the centering sections of the contacts essentially corresponds to the inclination of the guide bevels of the male part and the centering sections of the contacts are assigned to the untapered circumferential area of the cavities of the female part and the stop surfaces are offset by approximately 900 circumferential angles.
  • the width of the contact carrier section corresponds approximately to the maximum diameter of the sleeve-shaped section of the male part and thus also the diameter of the cylindrical cavity of the female part, the contact carrier section with its rounded front corners and edges in the worst case meets the mouth edges of the stop surface of the female part. A slight pressure is then sufficient to cause the male part to rotate and to be inserted more deeply.
  • the correct final coupling position of the contacts of the male part with the contact set of the female part takes place by mediating the contact surfaces, corners and edges of the components that come into contact with one another in the course of the progressive insertion.
  • a further feature of the invention is extremely advantageous, which consists in the fact that the die part rotatably supports a mounting sleeve for attachment to the lamp bracket. So that there is no overtightening that could damage the ladder, a circumferential stop that limits the angle of rotation is provided, which does not permit complete rotation by 3600.
  • a connector designated overall by 10 consists of two parts, namely a socket-shaped or sleeve-shaped matrix part 11 and a pin-like male part 12. Both the female part 11 and the male part 12 each have an insulating body 13 and 14 and contacts 15, 16 inserted therein . Two contacts 15 in the female part 11 and two contacts 16 of the male part 12 each form a contact set.
  • Each die part 11 has the shape of a flange sleeve which has two threaded sections 17 which extend over partial circumferential regions.
  • the die part 11 could be attached to a busbar, but according to the exemplary embodiment is intended for fastening in a bore in a lamp bracket, the flange 18 of the die part 11 being on the outside is supported on the wall of the lamp bracket and anchored to it by means of a nut screwed onto the thread 17 from the inside.
  • each die part 11 has two circumferential recesses 19 arranged opposite one another in the form of window-like openings.
  • the otherwise hollow circular cylindrical cavity 20 in the die part 11 is interrupted by surfaces 21 which, like the circumferential recesses 19, are arranged in pairs, but offset from them by 900 circumferential angles.
  • Each male part 12 is designed in the manner of a plug and has a sleeve section 22 for pressing onto the end of a support tube (not shown) for a lamp head, to which a flat contact carrier section 23 is connected on the plug side.
  • This has a flat rectangular shape, the width of each main surface 23a essentially corresponding to the diameter of the sleeve section 22 (FIGS. 1 and 3). All edges 24 and corners 25 of the contact carrier section 23 are rounded or beveled to form self-centering coupling aids.
  • the sleeve section 22 can also accommodate another support part, for example a cable, on which the lamp head hangs.
  • Both the male part 12 and the female part 11 each consist only of a possibly multi-part plastic injection molding for the relevant insulating body 13, 14 and two - in each case the same - contacts, which are made as simple stamped and bent parts from common contact material such as spring bronze.
  • the connector 10 is therefore very inexpensive to manufacture overall.
  • crimp sections are used, as shown in FIG. 2 for the contacts 15 there and designated 15a.
  • the sleeve section 22 of the male part 12 has - in a complementary adaptation to the inner contour of the female part 11 - locking hooks 26 on the one hand and flattenings 27 on the other hand.
  • the latching hooks 26 are arranged on webs 29 forming leaf springs, which are cut free from the jacket of the sleeve section 22 by means of two parallel incisions 28 each. They are only in material connection via their narrow ends 30 with the insulating material body 14. Therefore, each leaf spring 29 forms a surface line surface section of the sleeve 22.
  • Pushbuttons 31 are arranged near the latching hooks - likewise the leaf spring 29 is formed in one piece.
  • the leaf springs 29 are elastically biased outwards.
  • the latching of the plug connection takes place automatically when the male part 12 is inserted into the female part 11.
  • the easiest way to separate the connector parts is to place the thumb and index finger of one hand on the push buttons and by pressing them together the leaf springs 29 are actuated in such a way that the latching hooks 26 attached to them disengage inwardly from the openings 19.
  • the die part 11 of the connector 10 shown in FIGS. 3 and 4 is designed in its inner cavity like the die part 11 of the connector according to FIGS. 1 and 2.
  • its means 17, 18 for anchoring in the lamp console are provided on a separate part, namely an assembly sleeve 32.
  • the mounting sleeve 32 is snapped onto the die part 11 by means of an annular bead 33 and an annular groove 34 and is rotatably mounted thereon.
  • a nose 35 limits the possible rotation to a circumferential angle of less than 3600 in cooperation with a web (not shown in its circumferential movement path) on the die part 11.
  • the support part of the lamp head can therefore be moved about its longitudinal axis turn and with it the lamp head.
  • both the die part 11 and the male part 12 is coordinated with one another on a simple, automatically centering dome of the connector parts. If the male part 12 abuts approximately with its edges 25 on the mouth edges of the surfaces 21 of the male part, it inevitably rotates until it can enter the non-tapered section of the cavity 20. Further insertion of the plug part 12 allows its inclined surfaces 36 to impinge on the funnel-shaped guide sections 15b of the contacts 15, and again a final rotation into the final contact-correct position takes place here on the further axial plug-in path.
