Abstract

The invention discloses a fixing device and a fixing method of an M-type plastic optical fiber. The fixing device is assembled in a mode that a member B is inserted into a member A; when the member A is inserted into the member B, as a guide groove is designed at an interface of the member B, the optical fiber is easily inserted into the member A; during the process that the member B is pushed into the member A, as the front end of a part (5) of the member B takes the shape of an inclined plane and is shrunk due to the stress, the member A can be pushed into the member B; after the member A is pushed into the member B, as the rear end of the part (5) of the member B shapes like a plane, and the member B cannot be withdrawn from a part (6) of the member A due to the size, then the function of drop prevention is realized; however, the member A can be separated from the member B only by inwardly pressing the part (5) of the member B with a great force. As a part (2) of the member B takes the shape of an inclined plane and can bend automatically, when the member B reaches an appointed position, the part (2) of the member B can bounce up automatically, so as to achieve constant fastening.

Description

A kind of M plastic optic fibre fixing device and fixing means

Technical field

The invention belongs to the active photoelectric device class of plastic optical fiber communication products; It relates to provides single-shot, the single receipts or transceiving integrated module and optical fiber locking means; Be used for photoelectricity, electric light conversion; And, realize photoelectricity, electric light conversion and the transfer function of system equipment with Passive Optical Components such as active device such as light emission, light-receiving and plastic optical fiber coupling, fixing.

Background technology

Along with people's is to the increase of network bandwidth requirement, and to the deep exploitation of information transmission product, and market is satisfied the transmission medium that user performance requires and cost also constantly reduces and more and more is badly in need of various, wherein, and copper cable narrow bandwidth, poor anti jamming capability.Security and stability is poor, and maintainability is poor, and confidentiality is poor; The counter-bending ability of silica fibre, easily broken, installation property is poor, and price is high; Plastic optical fiber can remedy the shortcoming of above-mentioned copper cable and silica fibre, solves the access difficult problem of " last hundreds of rice ", and lightweight, cheap plastic optical fiber are progressively becoming the substitute of copper cash and silica fibre.

Because the special light connector on the glass optical fiber is not used in the application of plastic optical fiber, and directly uses plastic optical fiber to be connected with the plastics optical module, this will have special design to realize fixing and be connected plastic optical fiber with regard to requiring the plastics optical module.

Summary of the invention:

For reach between plastic optical fiber and the plastics optical module fixing be connected after lasting fastening; The invention provides and a kind ofly can realize effectively fixing between plastic optical fiber and the plastics optical module, as to be connected locking and release device, be called M plastic fibre lock and locking means.

To achieve these goals, of the present invention theing contents are as follows:

M plastic fibre lock of the present invention is to assemble through part B insertion parts A; Its structure is as shown in Figure 1, and the rear and front end of part B is left two hole I, II and is used for inserting optical fiber, the front opening of components A, and the rear end is left two hole I, II and is used for connecting optical fiber.

A kind of M plastic fibre lock of the present invention and optical fiber locking means; Its components A has two kinds of various structure; As shown in Figure 2, a kind of hole [1] of containing " mouth " type above being, its vertical view such as 2a are depicted as A1 spare; Another kind contains the hole [4] of a T-shape above being, its vertical view such as Fig. 2 b are depicted as A2 spare; Among among Fig. 2 a 7 and the 2b 8 is used for a locating slot making up each other with part B.Two hollow cone bodies are all arranged in the A parts of two kinds of structures; Its cone all is to be made up of three lobes; Its structure is shown in 6 among Fig. 3, and this structure helps the extruding force that the cone outside receives and can act on equably on three each stress surface of lobe shape, thus fixed fiber; The effect of components A be realize photoelectricity or electric light conversion module fixing, plastic optical fiber is led and clamps, and the locking after the optical fiber coupling realizes being connected of plastic optical fiber and photoelectricity module.

Contain a hook [2] and press points [3] above the described part B, the side is contained one and is mixed inclined-plane [5], and preceding half section is the plane for the inclined-plane second half section; The structure of part B is as shown in Figure 4.Part B is through [6] part of extruder member A; Realize fixed fiber, and cooperate with components A 1 top " mouth " type hole [1] or hole through the top T-shape of one above part B hook [2] and components A 2 cooperates sustainable locking optical fiber through one above part B hook [2].Through [3] part of pressing component B, [2] part of part B is separated with [1] part of components A 1, or [2] part of part B is separated with [4] part of components A 2, realize unlocking function.

After part B withdrawed from from components A, [9] part through components A cooperated with [5] part of part B, and part B is continued in card and the components A, and the realization pine does not take off function.Realized that finally lasting locking plastic optical fiber and releasing plastic optical fiber and part B pine do not take off function.

Embodiment

The embodiment of a kind of M plastic fibre lock provided by the invention and optical fiber locking means will combine accompanying drawing to further specify as follows: describe the best of the present invention below in conjunction with accompanying drawing and execute mode.

Like Fig. 5 (a) with (b); Components A is designed with the hole of " mouth " type [1] or " T " [4] type; When carrying out size design, generally design the same greatly with RJ11 or RJ45 to size CD and EF, be convenient to the user and when the system template perforate, cooperate with other parts; Size CD is designed to 13.84mm in the present invention, and size EF is designed to 16.26mm.

A kind of M plastic fibre lock locking plastic optical fiber method of the present invention is following:

Be inserted in the part B in components A, because be designed with gathering sill at the part B interface, optical fiber is easy to be inserted into components A, in the process of part B propulsive element A; [5] part front end of part B is the inclined-plane, and pressurized shrinks, and can push components A; After the propelling,, snap in [9] part of components A because [5] part rear end of part B is the plane; Realize that pine does not take off function, [5] part of inside pressure part B just can be separated components A with B energetically.

Because [2] part front of part B is the inclined-plane, can be curved down automatically, after part B reached assigned address, [2] of part B part was upspring automatically, realizes the locking that continues.

In the time of need taking off plastic optical fiber; As long as [3] part with part B presses down earlier, [2] part of part B promptly withdraws from from [1] or [4] of components A, can be with unclamping in part B and the components A; Realize release, gently draw plastic optical fiber just can plastic optical fiber be taken out from module again.

In use, after part B withdrawed from from components A, [9] part through components A cooperated with [5] part of part B, and part B is continued in card and the components A, and the realization pine does not take off function.Realized that finally lasting locking plastic optical fiber and releasing plastic optical fiber and part B pine do not take off function.
