Description
Technical field
The utility model relates to factory's prepackage connection device of tight-buffered fiber optic cable, is a kind of joints of optical fibre that are applicable to tight-buffered fiber optic cable specifically.
Background technology
In medical science, special optical fiber device, mine; Industry, numerous areas such as oil, tight-buffered fiber optic cable have application more and more widely; Different with the optical fiber flexible-cable that generally is used for fibre junction, tight-buffered fiber optic cable is a kind of special optical cable, and this optical cable often needs the crust hard-pressed bale or through the processing that blocks water; Its feature is simple in structure, and intensity is high, yet aims at the predispersed fiber end joint connector series formation as yet of tight-buffered fiber optic cable design.
With the existing preparatory termination SC of ordinary optic fibre flexible-cable factory (plug-type), LC (small-sized plug-type) joints of optical fibre is example, and in this type connector, during joints of optical fibre butt joint, optical fiber is in joint lock pin center.For keeping in touch, lock pin is under certain pressure state.After the length of spring compressed displacement, optical fiber excess length must be shunk back in optical cable.General inside cable leaves enough move places between 900 microns inner claddings of optical fiber or optical fiber and the oversheath, can optical fiber and optical cable crust is fixing respectively.And this connector construction is not suitable for tight-buffered fiber optic cable; This be because: the optical cable crust of tight-buffered fiber optic cable and optical fiber hard-pressed bale; Optical cable is hard owing to strengthening the indoor flexible-cable of texture ratio, after the length of spring compressed displacement, and the space that optical fiber excess length is not shunk back in optical cable; Thereby possibly produce microbend, cause optical fiber to fracture or the loss increasing.
The utility model content
To the defective that exists in the prior art; The purpose of the utility model is to provide a kind of joints of optical fibre that are applicable to tight-buffered fiber optic cable; Purpose is to solve tight-buffered fiber optic cable and is connected disconnected fibre with the joints of optical fibre, produces the added losses problem that fiber optic microbend causes in the assembling.
For reaching above purpose, the technical scheme that the utility model is taked is:
A kind of joints of optical fibre that are applicable to tight-buffered fiber optic cable is characterized in that, comprising:
Shell 1 is provided with the white shell 2 that is fixedly connected with it in its inner chamber,
Be provided with the back seat 6 that is fixedly connected with it in the inner chamber of white shell 2, back seat 6 is provided with through hole vertically,
Be provided with lock pin flange 4 in the cavity that back seat 6 and white shell 2 are enclosed, lock pin 3 is assemblied in the lock pin flange 4, is set with spring 5 at lock pin flange 4 outside surfaces, and the tail end of said lock pin flange 4 can move forward and backward in the through hole of back seat 6,
The rear side of back seat 6 is provided with locking strap 7.
On the basis of technique scheme, the rear side of locking strap 7 is provided with tail cover 8.
On the basis of technique scheme, the head end of lock pin flange 4 is provided with annular boss, and the head end of spring 5 and annular boss rear end face touch, and the tail end of spring 5 and back seat 6 touch.
The described joints of optical fibre that are applicable to tight-buffered fiber optic cable of the utility model; According to the characteristics design of tight-buffered fiber optic cable, change the mode of the contact of fiber stub, for tight-buffered fiber optic cable provides the series of indoor general purpose optical fiber connector; This design is applicable to SC (plug-type), LC (small-sized plug-type), MPO/MTP (multicore block form) connector; Part is few, assemble simple and easy, can with the tight-buffered fiber optic cable secure fixation.
Description of drawings
The utility model has following accompanying drawing:
The decomposition texture synoptic diagram of Fig. 1 the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explain.
As shown in Figure 1, the described joints of optical fibre that are applicable to tight-buffered fiber optic cable of the utility model comprise:
Shell 1 is provided with the white shell 2 that is fixedly connected with it in its inner chamber,
Be provided with the back seat 6 that is fixedly connected with it in the inner chamber of white shell 2, back seat 6 is provided with through hole vertically,
Be provided with lock pin flange 4 in the cavity that back seat 6 and white shell 2 are enclosed; Lock pin 3 is assemblied in the lock pin flange 4; Be set with spring 5 at lock pin flange 4 outside surfaces; The tail end of said lock pin flange 4 can move forward and backward in the through hole of back seat 6, and the effect of spring 5 is: keep lock pin 3 and connect equipment or optical cable and dock lock pin and be connected with certain pressure
The rear side of back seat 6 is provided with locking strap 7.
On the basis of technique scheme, the rear side of locking strap 7 is provided with tail cover 8.
On the basis of technique scheme, the head end of lock pin flange 4 is provided with annular boss, and the head end of spring 5 and annular boss rear end face touch, and the tail end of spring 5 and back seat 6 touch.
The utility model in use, step is following:
1, earlier tight-buffered fiber optic cable 9 is passed tail cover 8,
2, tight-buffered fiber optic cable 9 sheared to open to shell to optical fiber expose the length of optical cable crust to needs,
3, optical fiber is penetrated lock pin 3,
4, the optical cable crust is fixedly connected with lock pin flange 4 and gets final product through locking strap 7.
The movable part that lock pin 3, lock pin flange 4 are formed is not fixedly connected with back seat 6; In back seat 6, has the space that moves forward and backward; Optical fiber in the tight-buffered fiber optic cable is fixedly connected with movable part, and the optical cable crust in the tight-buffered fiber optic cable is fixedly connected with lock pin flange 4 through locking strap 7, then when lock pin 3 needs to move; Lock pin 3 and all movable parts and optical fiber can be synchronized with the movement, and do not produce the movable surplus length of optical fiber.A complete set of movable part is flexible in the cavity that back seat 6 and white shell 2 are enclosed, thereby has avoided optical fiber to fracture or the loss increasing.
When this connector docks with another connector, when connector ferrule moves, do not have relative motion between optical fiber and optical cable crust and the reinforcing element, thereby avoided disconnected fibre of optical cable or microbend.
This connector part is few, assembles simple and easy.
The content of not doing in this instructions to describe in detail belongs to this area professional and technical personnel's known prior art.
