Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as to restriction of the present utility model.
Please refer to Fig. 1 to Figure 12, the utility model provides a kind of multi-fiber connector, particularly a kind of Q-RMC (Quick look Multi-fiber connector, the fast insert-pull outdoor multi-core joints of optical fibre) the outdoor multi-core joints of optical fibre, comprise: the first housing 1, comprises clamping projection 2; Second housing 3, comprises the elasticity dog clutch 4 coordinated with clamping projection 2, and the end face of elasticity dog clutch 4 is formed with the first solution locking face 20; Unlock housing 5, be fastened on one end of the second housing 3 actively, unlock housing 5 and comprise the second solution locking face 21; One end of first housing 1 is inserted in the process of the second housing 3, and clamping projection 2 forces elasticity dog clutch 4 to expand outwardly and blocks the side of clamping projection 2; Unlock housing 5 in the process away from the first housing 1 direction motion, the second solution locking face 21 and be positioned at elasticity dog clutch 4 end face first is separated locking face 20 and is contacted, thus forces elasticity dog clutch 4 to expand outwardly to remove the locking to clamping projection 2.
Please refer to Fig. 1 and Fig. 2, during use, the first housing 1 is inserted in the second housing 3, along with the insertion of the first housing 1, under the effect of clamping projection 2, elasticity dog clutch 4 is outwards opened.When elasticity dog clutch 4 crosses clamping projection 2, the side of clamping projection 2 will be stuck in, thus be locked.
When the first housing 1 is separated with the second housing 3 by needs, unblock housing 5 is promoted to the direction away from the first housing 1, unlock housing 5 moving axially along the second housing 3, its the second solution locking face 21 is against on the first solution locking face 20, so, in moving process, unlock housing 5 and separate locking face 21 by second and apply an acting force to the end face of elasticity dog clutch 4, thus elasticity dog clutch 4 is outwards opened, to remove the locking to clamping projection 2.Like this, just the first housing 1 can be extracted from the second housing 3.Visible, the utility model can box Flange joint or connector box be molten finely connects, but make the first housing 1 and the second housing 3 direct-assembling, easy to operate.
Owing to have employed said structure, the utility model can utilize elasticity dog clutch 4 natural resiliency, and singlehanded drawing can realize auto lock and unlocking function, installs very convenient, has the advantages that structure is simple, cost is low.In addition, the utility model can also utilize existing multicore lock pin, thus reduces connector overall volume to greatest extent, thus the outdoor connector of the small-sized multicore forming vast capacity, the above dilatation of 4-48 core can be held.In addition, the space that the utility model does not need reserved hand to twist when mounted, has and takies the little feature of installing space.
In the utility model, the the second solution locking face 21 unlocking housing 5 abuts with the end face of elasticity dog clutch 4 all the time in moving process, therefore, only need to provide certain installation and activity space in the end of elasticity dog clutch for unlocking housing 5, reduce volume of the present utility model further, also save material simultaneously, reduce cost.
Preferably, second housing 3 is formed with back-up ring 6, the circumference of back-up ring 6 is provided with the first screw thread, unlock housing 5 and be provided with the second screw thread, the one end unlocking the second screw thread place of housing 5 is threaded through from the side near the first housing 1 of the first screw thread and departs from the first screw thread unblock housing 5 to be fastened on actively one end of the second housing 3.During installation, unlock housing 5 to be screwed into from one end of the second housing 3, then adopt the mode of " screw thread is threaded through head " that the second screw thread is departed from the first screw thread, thus unblock housing 5 is hung on the second housing 3 and can be up and down freely back and forth, and unlock the existence of housing 5 due to the second screw thread, not easily come off easily from the second housing 3.
