Protective device in a connector arrangement for optical fibers
View Patent ↗A plug for a connector arrangement consisting of a plug and an associated mating plug, has a housing which has at least one axial receiver for an optical fiber and a protective device movably mounted in the housing for protecting the optical fiber. The protective device according to the invention is designed as a slide which can be moved axially to the receiver and the slide has a aperture for the optical fiber and/or the receiver.
1. A plug for a connector arrangement consisting of a plug and an associated mating plug, comprising:
a housing which has at least one axial receiver for an optical fiber;
a protective device movably mounted in the housing for protecting the optical fiber;
the protective device is a slide which can be moved axially to the receiver and has an aperture for the optical fiber and/or the receiver, the slide is arranged in a starting position in front of the front end of the receiver in an unmated state and the front end of the receiver projects through the aperture in a mated state of the connector arrangement.
2. The plug according to claim 1 , wherein the movement direction of the slide corresponds to a plug-in direction in which the plug and mating plug are connected to one another.
3. The plug according to claim 1 , wherein the slide is produced as a part separate from the housing which can be inserted into the housing.
4. The plug according to claim 1 , wherein the slide is designed in the shape of a trough with a front end and side wall and guide elements which extend from the front end in the direction of the housing.
5. The plug according to claim 1 , wherein the housing comprises two or more axial receivers for a plurality of optical fibers, wherein one optical fiber respectively can be arranged in each receiver.
6. The plug according to claim 1 , further comprising a locking device which restricts movement of the slide in such a way that the protective function of the slide is retained if the plug is not connected to the mating plug.
7. The plug according to claim 6 , wherein the locking device is released upon a connection to the mating plug to release the axial movement of the slide.
8. The plug according to claim 6 , wherein the locking device comprises a locking projection which rests against a housing projection, so that the projections can be moved toward one another to release the locking.
9. The plug according to claim 6 , wherein the locking device or the housing contain a part which extends obliquely to the movement direction of the slide and which converts the movement of the mating plug upon connection into a movement to release the lock.
10. The plug according to claim 1 , further comprising a return device which returns the slide into the slide starting position upon detachment of the mating plug from the plug.
11. The plug according to claim 10 , wherein the return device comprises a latch which is arranged on the slide and rests with a correspondingly shaped projection on the mating plug when the connector arrangement is detached.
12. A plug for a connector arrangement consisting of a plug and an associated mating plug, comprising:
a housing which has at least one axial receiver for an optical fiber;
a protective device movably mounted in the housing for protecting the optical fiber;
the protective device is a slide which can be moved axially to the receiver and has an aperture for the optical fiber and/or the receiver; and,
a locking device which restricts movement of the slide in such a way that the protective function of the slide is retained if the plug is not connected to the mating plug.
13. The plug according to claim 12 , wherein the locking device is released upon a connection to the mating plug to release the axial movement of the slide.
14. The plug according to claim 12 , wherein the locking device comprises a locking projection which rests against a housing projection, so that the projections can be moved toward one another to release the locking.
15. The plug according to claim 12 , wherein the locking device or the housing contain a part which extends obliquely to the movement direction of the slide and which converts the movement of the mating plug upon connection into a movement to release the lock.
16. The plug according to claim 12 , further comprising a return device which returns the slide into the slide starting position upon detachment of the mating plug from the plug.
17. The plug according to claim 16 , wherein the return device comprises a latch which is arranged on the slide and rests with a correspondingly shaped projection on the mating plug when the connector arrangement is detached.
