| Full Text | The invention relates to a duplex conntctort comprising two fastening devices for receiving two simplex plug- in connectors for forming a duplex plug-in connector. A duplex connector of the generic type in question is disclosed by US 979,429. The duplex connector comprises a plate- shaped element, on the side walls of which two differently designed cylindrical pins are respectively arranged and can be inserted into corresponding holes in a connector housing of a simplex connector. Arranged on the upper side of the plate-shaped element is a clip—shaped element, which in the assembled state engages around the latching clips of the simplex plug-in connectors, so that the two latching clips of the simplex plug-in connectors can be simultaneously released by actuation of the clip-shaped element. The simplex plug-in connectors are formed with holes on both sides of their housing, so that each simplex plug-in connector can be arranged on either side of the duplex connector. As a result, it is possible for example for the channels to be subsequently changed over by exchanging or changing the simplex plug-in connectors. Consequently, the duplex conntctor allows a duplex plug-in connector to be produced from two simplex plug-in connectors. A further advantage is that, when one simplex plug-in connector is defective, only this defective plug-in connector has to be exchanged. The disadvantage of the known duplex connector is the inadequate quality of the mechanical connection and its limited suitability for use. The invention is therefore based on the technical problem of providing a duplex connector for optical fiber plug-in connectors which can be used universally and realises an improved mechanical connection between a duplex connector and a plug-in connector. The technical problem is solved by the device having the features of the invention. Further advanta- geous developments of the invention emerge from the essential features of the invention. In this respect, the fastening devices are designed in such a way that they at least partially enclose the connector housing and/or the kink preventer of a plug-in connector to be received. As a result, the plug-in connector to be received is securely clamped by the fastening device, the clamping forces being distributed around the plug- in housing in a way corresponding to the design of the fastening device. A further advantage of the duplex connector according to the invention is that it does not require any mechanical provisions on the plug-in connector itself. As a result, the duplex connector can be used universally for plug-in connectors from various manufacturers. In a preferred embodiment,the fastening devices are designed as C-shaped receptacles, so that they securely clamp the respective kink preventer in a resilient mannar. In this case, the open legs of the C-shaped receptacle are preferably formed with a bevel in order to faciliate the insertion of the plug-in connector. In a further preferred embodiment, a right-angled receptacle adjoins the C-shaped receptacle in the longitudinal direction of the duplex connector. This right-angled receptacle serves for securely clamping part of the connector housing. Consequently, the plug-in connector is securely clamped by the duplex connector on the kink preventer and the connector housing simultaneously, which brings about a particularly secure mechanical connection. The right-angled receptacle is preferably essentially of an L-shaped form, the open legs preferably being formed with a bevel. Furthermore, the L-shaped receptacle is formed with a web which protrudes over the upper side of the connector housing. In a further preferred embodiment, a clip-shaped element is arranged on the upper side in such a way that, in the fastened state of the simplex plug-in connectors, it engage, over the clips of the latter so that, by actuation of the clip—shaped element, the two clips of the simplex plug-in connectors are actuated simultaneously. The invention is explained in wore detail below on the basis of a preferred exemplary embodiment. In the figures : Figure 1 shows a perspective rear view of a duplex connector, Figure 2 shows a perspective front view of the duplex connector. Figure 3 shows a side view of the duplex connector, Figure 4 shows an exploded representation of the duplex connector with two simplex plug-in connectors, Figure 9 shows a duplex plug-in connection comprising a duplex connector and two simplex plug-in connectors in the assembled state and Figure 6 shows a side view of the duplex plug-in connection. The duplex connector 1 comprises an upper side 2 and a lower side 3, between which a web-shaped wall element 4 is centrally arranged. Arranged on each side of the wall element 4 is a C-shaped receptacle 5 and an L-shaped receptacle 6. The C- shaped receptacles 9 extend over the full width of the duplex connector 1. The end faces 7 of the upper legs are formed with a bevel 8 and the end faces 9 of the lower legs are formed with a bevel 10. The end face 9 of the lower leg extends over the full length L of the duplex connector 1, whereas the end face 7 extends only as far as the L-shaped receptacle 6. Arranged parallel to the upper side 2 of the duplex connector 1 in the region of the L-shaped receptacle 6 is a web 11, which is somewhat narrower than the width B of the duplex connector 1. The web 11 is likewise formed with a bevel 12. The length of the C-shaped receptacle 5 is in this case somewhat more than twice the length of the L-shaped receptacle 6. Arranged on the upper side 2 is a clip-shaped element 13, which extends at an angle from the front side to the rear side and goes into a part parallel to the upper side 2. Represented in Figure 4 is the duplex connector 1 from Figures l-3, with the simplex plug-in connectors 14. The two simplex plug-in connectors 14 are of a completely identical construction. Each simplex plug—in connector 14 comprises the actual optical fiber cable 15, a cable sheath fixing means 16, a kink preventer 17 and the connector housing 18. The kink preventer 17 is made up of a conical part and a cylindrical part the cylindrical part facing the connector housing 18. Arranged on the connector housing 18 is a snap clip 19 which serves for latching and releasing the plug-in connector 14 in a corresponding receptacle. The connector housing 18 itself is of an essentially cuboidal design. The snap clip 19 is made up of a latching clip 20 and a releasing clip 21, which is explained in more detail with reference to Figure 6. Represented in Figure 9 is the complete duplex plug-in connector 22. In this caset the cylindrical part of the kink preventer 17 is securely clamped in the C-shaped receptacle 9 and part of the connector housing 18 is securely clamped in the L-shaped receptacle 6. The lateral gripping of the end faces 7, 9 with their bevels 8, 10 around the receptacles 5, 6 makes the clamping connection mechanically very stable. The clip-shaped element 13 is in this caw ovtr both the clips 19 of the two simlplex plug-in connectors 14, so that they can be simultaneously released. As can be seen from figure 6, the releasing clips 21 are over the latching clips 20 and the clip-shaped element 13 is over the releasing clips 21. If the duplex plug-in connector 22 is then fitted into a corresponding receptacle, the latching clips 20 latch into the receptacle . Pressure on the sloping part of the clip-shaped element 13 causes the releasing clips 21 likewise to be pressed downward. These in turn press the latching clips 20 downwardt so that all the clips are unlatched and the duplex plug-in connector 22 can be released. WE CLAIM 1.
