Abstract
Disclosed in the invention is a multi-core fiber connector comprising a first housing, a second housing, and a delocking housing. The first housing includes a clamping protrusion. The second housing consists of an elastic claw buckle cooperating with the clamping protrusion; and a first delocking surface is formed at the end surface of the elastic claw buckle. The delocking housing clamped at one end of the second housing movably has a second delocking surface. When one end of the first housing is inserted into the second housing, the clamping protrusion forces the elastic claw buckle to expand externally and one side of the clamping protrusion is clamped; and when the delocking housing is moved towards a direction far away from the first housing, the second delocking surface is in contact with the first delocking surface formed at the end surface of the elastic claw buckle, so that the elastic claw buckle is forced to expand externally to release locking of the clamping protrusion. On the basis of the structure, because of elasticity of the elastic claw buckle, automatic locking and delocking functions can be realized based on single-hand drawing; and installation of the connector becomes convenient. Moreover, the connector has characteristics of simple structure and low cost.

Detailed description of the invention
With specific embodiment, the present invention is described in further detail below in conjunction with the accompanying drawings, but does not makees
For limitation of the invention.
Refer to Fig. 1 to Figure 12, the invention provides a kind of multi-fiber connector, particularly one
(Quick look Multi-fiber connector, fast insert-pull outdoor multi-core optical fiber is even to plant Q-RMC
Connect device) the outdoor multi-core joints of optical fibre, including: the first housing 1, including clamping projection 2；The
Two housings 3, including the elastic dog clutch 4 coordinated with clamping projection 2, the end face of elastic dog clutch 4 is formed
There is the first solution locking face 20；Unlock housing 5, be fastened on one end of the second housing 3 actively, unlock
Housing 5 includes the second solution locking face 21；During the second housing 3 is inserted in one end of first housing 1,
Clamping projection 2 forces elastic dog clutch 4 to expand outwardly and block the side of clamping projection 2；Unlock housing
5 during away from the first housing 1 direction motion, and second solves locking face 21 and be positioned at elastic dog clutch 4
First solution locking face 20 contact contact of end face, thus force elastic dog clutch 4 expand outwardly to release right
The locking of clamping projection 2.
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, makes elastic dog clutch 4 be flared out.When
When elastic dog clutch 4 crosses clamping projection 2, the side of clamping projection 2 will be stuck in, thus locked
Fixed.
When the first housing 1 is separated by needs with the second housing 3, housing 5 will be unlocked to away from first
The direction of housing 1 promotes, and unlocks housing 5 moving axially along the second housing 3, its second unblock
Face 21 is against on the first solution locking face 20, then, in moving process, unlocks housing 5 by second
Solve locking face 21 and apply an active force to the end face of elastic dog clutch 4, thus by outside for elasticity dog clutch 4
Open, to release the locking to clamping projection 2.So, just can be by the first housing 1 from the second shell
Body 3 is extracted.Visible, the present invention can connect by the molten fibre of box Flange joint or connector box, and
It is to make the first housing 1 and the second housing 3 direct-assembling, easy to operate.
Owing to have employed said structure, the present invention can utilize elastic dog clutch 4 natural resiliency, singlehanded
Drawing can realize auto lock and unlocking function, installs very convenient, has structure letter
Single, the feature of low cost.It addition, the present invention can also utilize existing multicore lock pin, thus
Limits reduces adapter overall volume, thus constitutes the small-sized multicore outdoor connection of vast capacity
Device, can accommodate the above dilatation of 4-48 core.Additionally, the present invention need not what reserved hands was twisted when mounted
Space, has and takies the feature that installing space is little.
In the present invention, unlock housing 5 second solution locking face 21 in moving process all the time with elastic claw
The end face of button 4 abuts, thus, it is only required to provide one in the end of elastic dog clutch 4 for unlocking housing 5
Fixed installation and activity space, reduce the volume of the present invention further, also saves simultaneously
Material, reduce cost.
Preferably, the second housing 3 is formed back-up ring 6, the circumference of back-up ring 6 is provided with the first spiral shell
Stricture of vagina, unlocks housing 5 and is provided with the second screw thread, unlock housing 5 the second screw thread place one end from
The side near the first housing 1 of the first screw thread is threaded through and departs from the first screw thread will unlock housing 5
It is fastened on one end of the second housing 3 actively.During installation, unlock housing 5 from the one of the second housing 3
End is screwed into, and then uses the mode of " screw thread is threaded through head " that the second screw thread is departed from the first screw thread,
Hang on the second housing 3 and can be the most up and down so that unlocking housing 5, and
Unblock housing 5, due to the existence of the second screw thread, is difficult to come off easily from the second housing 3.
In one embodiment, this first solution locking face 20 is inclined-plane.In another embodiment,
The end of elastic dog clutch 4 is crozier, and the end face of the inclination of crozier constitutes described first and solves locking face
20.This way it is not necessary to it just can be made outside the shape that elastic dog clutch 4 is arranged to arc on the whole
Expansion, thus, simplify processing and manufacturing process.In the two embodiment, due to first
Solve locking face 20 and be the inclined-plane of inclination, thus, when unlocking axial along the second housing 3 of housing 5
Time mobile, owing to its second solution locking face 21 is the most also moving axially along the second housing 3, and
The the first solution locking face 20 abutted with the second solution locking face 21 is inclined-plane, thus, second solves locking face 21 meeting
Move relative to this inclined-plane, so that elastic dog clutch 4 expands outwardly to release the lock to clamping projection 2
Fixed.Preferably, the second solution locking face 21 is to have the inclined-plane matched with this first solution locking face 20.
