Definitions

  • the invention relates to an adapter for producing an optical plug connection according to the preamble of claim 1.
  • Such adapters are used to couple incompatible plug parts to one another.
  • the pawl mechanism is particularly advantageous as a quick coupling, because the coupling process can be carried out by simple pressure in the axial direction of the socket. It has proven to be particularly advantageous if the pawl mechanism has two pawls movably mounted on the holding plate, which pawls can be locked against a biasing force behind corresponding abutments on the counterplate. The coupling forces are evenly distributed over the two pawls and the Preload ensures that the pawls cannot be released unintentionally.
  • the two pawls can be arranged on a slide which is slidably mounted on the holding plate transversely to the axial direction of the socket and which is biased into the closed position by means of at least one spring.
  • the sliding direction of the slide means there are no or only very small bending moments on the coupling. If the slide is a bent part made of metal, the pawls can be integrated particularly easily.
  • the slide can also have a bend formed as a grip piece, which overlaps an end face of the holding plate, the spring being a helical compression spring arranged between the end face and the bend. This angling results in particularly high ease of use. To release the quick coupling, simply push the slider on the handle to release the pawls.
  • the slider can be fastened to the holding plate by means of holding screws which are screwed into the holding plate through elongated holes in the slider.
  • Other management means such as lateral grooves or the like would be conceivable.
  • a particularly advantageous coupling is achieved if the locking flanks of the locking pawls which bear against the abutments in the closed position are inclined to compensate for play in their direction of movement.
  • the preload force on the pawls means that they always run up against the abutments and thus the holding plate is pressed against the counterplate without play.
  • FIG. 1 shows a perspective illustration of an adapter and a counterplate before the coupling
  • FIG. 2 the adapter according to FIG. 1 in the coupled state
  • FIG. 3 shows a cross section through a device wall with a counterplate and with a first plug part
  • FIG. 4 shows a perspective exploded drawing of the adapter according to FIG. 1,
  • FIG. 5 the adapter according to FIG. 1 viewed from the opposite side
  • FIG. 6 shows a side view of the adapter according to FIG. 1 when approaching the counterplate
  • Figure 7 the adapter according to Figure 6 in the coupled state
  • Figure 8 shows an overall arrangement consisting of a total of 6 adapters with different coupling means.
  • an optical plug connection 2 essentially consists of an adapter 1, which serves to connect the first plug pin 7 of a first plug part and the second plug pin 8 of a second plug part 4 (FIG. 2) to one another, different coupling means 32 can be used to couple the second plug part to the adapter.
  • the adapter 1 has a holding plate 5 which can be connected to a counter plate 12.
  • the counter plate 12 is screwed to a device wall 15 in the exemplary embodiment with the aid of fastening screws 16.
  • Bolts 14, 14, which serve as abutments for the pawls 13, 13 of the adapter, are fastened to opposite end faces of the counterplate 12.
  • the first plug pin 7 protrudes through a central opening 33.
  • Recesses 17 are arranged around this central opening in a uniform angular division, the function of which will be described below.
  • a positioning hole 18 is used for angular positioning of the adapter on the counter plate 12. Further details of the attachment of the first plug part 3 can be found in FIG. 3.
  • the counter plate 12 has a flange 19 with an external thread on the side facing the device wall 15.
  • the union nut 20 of the first plug part 3 can be screwed onto it, the first plug pin 7 being positioned exactly at the same time.
  • the first plug part 3 could also be connected to the counterplate 12 with other detachable coupling means. As shown, the end face of the first connector pin 7 protrudes somewhat beyond the plane of the counterplate 12.
  • FIGS. 4 and 5 Further details of the adapter 1 can be seen from FIGS. 4 and 5.
  • the aforementioned holding plate 5 is connected to a slide 21 on the device side 9 facing the first plug part 3.
  • the slide 21 has elongated holes 26 through which fastening screws 28 can be screwed into the holding plate 5. Spacers 29 ensure that the slide remains movable in the direction of arrow a, insofar as the elongated holes 26 permit this.
  • a positioning bolt 27, which penetrates the slide 21, is also fixed in the holding plate 5.
  • the slide itself is designed as a one-piece bent part made of metal, with the pawls 13 13 being arranged on the side.
  • a bend 23 overlaps an end face 11 of the holding plate 5. Between the bend and the end face, two helical compression springs 22, 22 ⁇ are held captively, so that the slide 21 is always biased into a locked position.
  • lateral guide strips 31 are also provided on the holding plate 5.
  • the holding plate 5 carries the actual socket 6, which centers the two connector pins on one another.
  • This bushing is preferably mounted in a floating manner in a bushing bearing 30 which also penetrates the slide 21 at a central opening 34.
  • Coupling means 32 for receiving the second plug part 4 are on the side 10 of the holding plate 5 facing away from the counterplate 12 ( Figure 2) arranged, which coupling means are respectively adapted to the second connector parts to be accommodated.
  • FIGS. 6 and 7 When coupling the adapter to the device wall or to the counter plate 12, the following process takes place according to FIGS. 6 and 7:
  • the adapter 1 is pressed against the counter plate 12 in the direction of arrow b), namely in the axial direction of the bushing mounted in the adapter.
  • an angular positioning takes place first, the positioning bolt 27 penetrating into the positioning bore 18.
  • the ramp flanks 24 of the pawls 13, 13 ⁇ run on the bolts 14, 14 ⁇ , the inclined position being selected such that the slide is pressed downward against the force of the helical compression springs 22, 22 ⁇ .
  • the heads of the mounting screws 28 dip into the recesses 17 of the counter plate 12 (Fig. 1).
  • FIG. 8 The total of 6 different adapters la to If can all be coupled to the counter plate 12 or to the first plug part using the pawl mechanism described above.
  • the rear coupling means are different.
  • the adapter la has coupling means for connecting a DIN plug with a screw-on union nut.
  • the adapter lb is equipped for an FC-PC connector, which is also screwed on.
  • the adapter 1c can accommodate an ST plug, which is coupled using a bayonet lock.
  • the adapter Id can accept an E-2000 connector with pawl lock.
  • the adapter le is equipped for SC connectors, the coupling mechanism of which has a push-pull system.
  • an F-3000 connector can be connected to the adapter lf, the coupling mechanism of which is similar to that of the E-2000 standard.
  • additional adapters could be provided.

Abstract

L'invention concerne un adaptateur (1) permettant de relier la pointe de contact (7) d'une première partie de fiche (3) à la pointe de contact (8) d'une deuxième partie de fiche (4). Cet adaptateur est pourvu d'une plaque de maintien (5), sur laquelle est maintenue une douille (6) destinée au logement concentrique des pointes de contact. Cette plaque de maintien (5) peut être raccordée à une contre-plaque (12) à l'aide d'un mécanisme à encliquetage (13, 13`, 14, 14`), laquelle contre-plaque supporte la première partie de fiche (3). Ledit mécanisme à encliquetage est précontraint par ressort et une simple pression en sens axial est nécessaire à son enclenchement.
