Definitions

  • the invention relates to a snap-in unit for an electrical connector comprising a body arranged to accomodate the connector, preferably a female connector, and provided with a socket, the front face of which includes an insert opening for the connector. Further the invention relates to a plate with an aperture for this snap-in unit.
  • the object of the invention is to facilitate the manufacture and mounting of connectors, especially telephone connectors for data communication, and to enable such connectors to be mounted without the use of tools, to be reliably retained, easy to dismount, possibly with the use of tools, and to be turned and orientated as desired in situ.
  • This snap-in unit is characterised in that the socket including the connector is substantially rigid and has a quad­ratic cross section and that locking means are provided on at least two sides so as to co-operate with other locking means in connection with a rigid plate with a quadratic aperture able to accomodate the quadratic socket of the snap-in unit in such a way that the quadratic front face is substantially parallel to the front surface of the plate.
  • the snap-in unit according to the invention implies that because of the quadratic cross section, said snap-in unit can be mounted in four different ways by turning said unit. (The front surface with the insert opening must, of course, still be in substan­tially the same plane, i.e. parallel to and almost flushing with the surface of the mounting plate) The latter enables an electrician to choose on the basis of the local wiring how to orientate the connector in the best possible manner.
  • the locking means of the snap-in unit are preferably identical on all four sides and are capable of co-operating with the corresponding locking means on the plate.
  • the locking means of the snap-in unit are preferably in the form of two locking projections and a stop projecting from each side.
  • the locking means of the plate are preferably two opposite flexible locking flaps adapted so as to fit closely to the snap-in unit.
  • the locking flaps co-operate with the stop and with the locking projections engaging the slots of the locking flaps thereby securing a reliable retention of the connector when subjected to stress from outside, where only the front surface of the connector is accessible. Dismounting can only take place from behind by bending the locking flaps aside by means of a tool, e.g. a screwdriver.
  • the invention furthermore relates to a plate onto which the snap-in unit is mounted.
  • the plate may e. g. be a steel plate with a plurality of quadratic apertures for use in a main distributing frame or a mounting plate of plastic material in the form of a socket box front plate for a wall outlet from a cable channel and provided with one or two aper­tures.
  • the plate is a rather small mounting plate adapted for mounting in a special data connector with a down­wards inclining outlet surface, particularly suit­able for thick cables which are so rigid that they hardly stand bending at 90°.
  • a snap-in unit according to the invention comprises a body 10 formed around a female connector of some kind, particularly a standard telephone plug, adapted to receive a cable from a subscriber's telephone.
  • One end of the snap-in unit 10 is of a quadratic cross section, as is obvious from Figures 1 and 2, and is provided with a number of locking projections 20 on each side surface 12, 14, preferably two on each side. Moreover, each side surface is provided with at least one stop 22.
  • An opening 18 is seen on the front face of the snap-in unit, said opening being adapted for the insertion of a complementary connector on a cable connected to a telephone.
  • the stop 22 is to ensure that the snap-in unit is placed correctly and firmly in an associated plate 30 (shown in Figure 4) provided with quadratic aper­tures 32 so as to co-operate with the snap-in unit 10.
  • the plate 30 may be part of a socket box in a wall or in a cable channel, but may also be part of a larger installation in the form of a main distributing frame.
  • the plate is provided with clip means 34 adapted to co-operate with the locking projections 20 and the stops 22.
  • the locking projections 20 are preferably provided with an inclined surface 21 facilitating the in­ sertion of the snap-in unit and being provided with a vertical rear rim 23 so as to co-operate with the clip means in retaining the snap-in unit.
  • the stops 22 may be shaped in many ways, but preferivelyably they have a perpendicular front rim, which- upon insertion of the snap-in unit in a plate- abut) part of the plate 30 or its clip means.
  • the clip means comprises two locking flaps, each mainly with the form of a rectangle of almost the same length as the rim of the aperture and half the width and provided with two openings or well-­defined slots 36 whose positions correspond to the locking projections 20 of the snap-in unit 10. Both locking flaps are almost perpendicular to the plate 30 - with a slight tendency to incline towards the aperture, as is suggested in Figure 7. The inclination ensures that the locking flaps tightly abut the inserted snap-in unit.
  • the middle section of the rim 38 of the locking flaps facing away from the apertured plate is adapted to form a rest for the stop 22 of the snap-in unit 10.
  • the corners of the locking flaps are provided with two projec­tions with inclined guiding surfaces on the side facing the snap-in unit in order to facilitate the insertion of the snap-in unit.
  • Adjacent to the guiding surfaces 40 is a rim portion defining the slot 36.
  • the rim portion has been provided with an inclined guiding surface 42 which guides the locking projection 20 into the slot during the insertion of the snap-in unit.
  • the plate 30 is a mounting plate or a front plate, as shown in Figure 4, of a socket box, preferably of the LK-FUGA series (trademark).
  • a socket box preferably of the LK-FUGA series (trademark).
  • Such mounting plates and socket boxes are described e.g. DE-A-37 17 363 and DE-U-86 31 155.7.
  • This plate is made of plastics and the locking flaps may be moulded integrally with the plate by using the appropriate moulding tools.
  • Figure 4 is a front view of the plate with the aperture 32 and the locking flaps 34 facing backwards discernible along the rim of the aperture. Because of the shape of the moulding tools, there are four notches along the rim in this embodiment, one for each slot 36 of the locking flaps.
  • the aperture 32 there are only locking flaps 34 along two opposing rims of the aperture 32 which facili­tates the dismounting of the snap-in unit. If there were locking flaps along all four rims, it would be difficult to loosen all four locking engagements at the same time .
  • the snap-in unit 10 In the interior of the snap-in unit 10 space has been provided for some form of standard plug, e.g. a telephone plug.
  • the front portion of the snap-in unit must according to the invention be of a quad­ratic cross section. However, the rear portion of the socket box may be shaped freely so as to match the type of connector used. As shown in Figures 1, 2 and 3, the snap-in unit may therefore have pro­jecting parts 24.
  • the quadratic portion of the snap-in unit measures 15.2 x 15.2 mm, these dimensions providing just enough space for a "modul jack 6/8P" telephone plug.
  • a plate with one or two apertures 30 is preferably used, as shown in Figure 4, said apertures being provided with clip means along the side rims as shown in Figures 5 and 6.
  • the plate On the rear side the plate may be provided with a number of stiffening ribs thereby ensuring a sufficient rigidity of the plate in relation to the forces of tension and compression it may be subjected to.
  • the plate is provided with an aperture 32 and clip means 34 capable of retaining a snap-in unit 10.
  • the diagonal cover is especially suited for the connection of thick and rather rigid cables.
  • the snap-in unit according to the invention may also be used for main distributing frames.
  • Figure 10 shows a section of a plate to be used in a main distributing frame.
  • I-shaped slots and holes 36 are punched in a plate, e. g. of steel.
  • the resulting flaps 34 are subse­quently bent around 90°, thereby forming the clip means 34, as shown in Figures 12 and 13.
  • the plate is easy to manufacture and the material removed from the apertures may be used to form the clip means.
  • the snap-in unit described above can be mounted without the use of tools, only by pressing the snap-in unit into the aperture of the associated mounting plate from behind, said mounting plate either being a front plate moulded in plastics, e.g. for a switch, or a metal plate as shown in Figure 10.
  • the locking flaps 34 closely abut the side surfaces of the snap-in unit 10 and the locking projections engage the slots 36.
  • the connector is thus reliably secured during use.
  • the connector will not loosen from the plate onto which it has been mounted even if subjected to a substantial inwards pressure, e.g. when a telephone plug is inserted in the connector from outside.
  • This is among other things due to the combination of firm locking projections 20 and resilient locking flaps 34 completely abut­ting the quadratic block which makes up the body of the snap-in unit, said body being rather rigid per se. The combination does not yield to an inward pressure.
  • the snap-in unit is to be moved after the mount­ing, it is released by forcing the locking flaps away from the locking projections 20 and subsequent­ly by pulling out the snap-in unit.
  • a small screw­driver or just a nail is sufficient tool to release the snap-in unit.
  • the snap-in unit according to the invention may be shaped in many different ways.
  • Figures 14 and 15 thus show alternative embodiments in which the locking means of the snap-in unit have been replaced by a wholly or partially circumferential groove 26 in the body of the snap-in unit.
  • the groove 26 is capable of co-operating with a latch 28, insertable in the groove following the insertion of the snap-­in unit into an aperture 32.
  • the stops 22 may be replaced by a wholly or partially circumferential, projecting edge or collar 22. If the connector type in question is sufficiently small, the snap-­in unit may be made without the projecting parts 24. In that case the snap-in unit must be provided with a collar 48 adapted to abut the front surface of the mounting plate. According to this embodiment, the snap-in unit is thus adapted to be inserted from the front into the plate and is fastened from behind e.g. by means of a latch 28.
  • the snap-in unit may have a cylindrical body provided with locking projections 20 and locking knobs 22 which between them provide the base portion of snap-in unit with a substantially quadratic cross section. Such an embodiment may be advantageous for small coaxial connectors.
  • Figure 17 shows an embodiment consisting of a body 10 with a quadratic cross section and with a locking means in the form of two projecting strips, between them forming a deep groove which the rim of the aperture of the plate 30 can engage.
  • this snap-in unit is inserted by letting the rim of the plate engage the groove and tilting the snap-in unit in place, using the rim as the axis of rotation.
  • the snap-in unit is retained by means of one or more locking projections 20, which e.g. may be shaped like the locking projections described above and which may engage a notch, e.g. of a locking flap 34, as shown and described in connection with Figures 6 and 7.
  • the snap-in unit is provided with locking means on two sides adapted to co­operate with other locking means on the plate. It will thus be understood that the invention may be varied in many different ways and that the snap-­ in unit according to the invention is adaptable to other types of connectors, telephone connectors only being mentioned as a typical example of the application.
