Abstract

The invention discloses a locking device and a locking method of a U-shaped plastic optical fiber. The locking device comprises two parts, namely a member A and a member B, and is assembled in a mode that the member B is inserted into the member A; a part (2) of the member B is arc-shaped; when the member B reaches an appointed position of the member A, the part (2) of the member B is embedded into a part (1) of the member A, and the member B and the member A are mutually clamped so as to realize the constant fastening of the two members. When the plastic optical fiber needs to be taken down, the member B needs to be pulled outwards firstly, the part (2) of the member B withdraws from the part (1) of the member A, then the member A is released from the member B, and the unlocking is implemented, and then the plastic optical fiber is taken out.

Description

A kind of U plastic fibre lock and locking means

Technical field

The invention belongs to the plastic optical fiber communication products of active photoelectric device class; 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 the great development of economy, every family is also increasing to the demand of network information product.But copper cable that uses at present and quartzy optical cable have run into huge difficulty, concerning copper cable because himself when coming into huge numbers of families; A large amount of installations need the valuable metals resources of waste; And its narrow bandwidth, poor anti jamming capability, security and stability is poor; Maintainability and confidentiality are all very poor, can not satisfy user's demand; Concerning silica fibre, its counter-bending ability, easily broken, installation property is poor, and price is high; How to solve the access difficult problem of " last hundreds of rice ", the plastic optical fiber that can remedy the shortcoming of above-mentioned copper cable and silica fibre is progressively becoming the substitute of copper cash and silica fibre.

But, because the special light connector on the glass optical fiber is not used in the application of plastic optical fiber, but directly use 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.Design and the supporting optical-electric module of preparation plastic optical fiber are promoted the application of plastic optical fiber product at communication field, the object of the invention just.

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 U plastic fibre lock and locking means.

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

U plastic fibre lock according to the invention, it is made up of components A and part B two parts;

Components A of the present invention is to be formed by plastic injection-moulded; Its shape is as shown in Figure 1, and the upper inner surface of components A respectively has " recessed " type part [1] with following inside surface, and a pair of cylinder [5] that is used for fixing radome is arranged on components A; Two hollow cone bodies [3] are arranged in components A inside; Its cone all is to be made up of three lobes, 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; , components A up and down two " recessed " type parts [1] and part B two " protruding " types up and down partly [2] cooperate and be used for fixing components A and part B and plastic optical 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.

Part B of the present invention is to be formed by plastic injection-moulded, and its shape is as shown in Figure 2, and Fig. 2 (a) is the part B stereographic map; Fig. 2 (b) is the part B side view; Fig. 2 (c) is the part B rear view, from figure [6] 2 (c), can find out have a pair of optic fibre hole [6] to be used for inserting optical fiber in the part B; From Fig. 2 (a), Fig. 2 (b), can find out, part B " protruding " type part [2] respectively arranged up and down, there is a pair of hook that stretches out [4] side of part B; The top of hook [4] is made into the inclined-plane, and the front end of hook [4] is the wide-angle inclined-plane, and pressurized shrinks; Can easily push components A; After the propelling, the rear end is the low-angle inclined-plane, is difficult for easily withdrawing from; [2] part of part B is made into certain shape, after part B reaches assigned address, and " recessed " type part [1] phase interlock fixed part B and the components A of " protruding " type of part B part [2] built in items A.

The locking means synoptic diagram of a kind of U plastic fibre lock of the present invention is as shown in Figure 3, is inserted in the components A in part B, because be designed with gathering sill at the part B interface; Optical fiber is easy to be inserted into components A, and in the process of part B propulsive element A, [4] part front end of part B is the inclined-plane; Pressurized shrinks, and can push components A, after the propelling; Because [4] part rear end of part B is the low-angle plane, snaps in [6] part of components A, realize that pine does not take off function; [4] part of inside pressure part B just can be separated components A with B energetically.

[2] part of part B is made into certain shape, and after part B reached assigned address, [2] of part B were partially submerged into [1] part of components A, and interlock realizes the lasting locking of two parts each other.

In the time of need taking off plastic optical fiber, need earlier part B to be pulled outwardly, [2] part of part B promptly withdraws from from [1] of components A, can part B be unclamped from components A, realizes release, gently draws plastic optical fiber just can plastic optical fiber be taken out from module again.

Embodiment

The embodiment of a kind of U plastic fibre lock provided by the invention and optical fiber locking means will combine accompanying drawing to further specify as follows:

Components A generally designs the same greatly with RJ11 or RJ45 to size CD and EF when carrying out size design, is convenient to the user and when the system template perforate, cooperates with other parts, and size CD is designed to 13.84mm in the present invention, and size EF is designed to 16.26mm.

[2] part of part B is made into arc, and after part B reached assigned address, [2] of part B were partially submerged into [1] part of components A, realizes the lasting locking of two parts each other as mutual interlock.In the design, the height size of the arc size of [2] of part B has determined the locking intensity of U plastic fibre lock, and therefore, the design's key is the design of the height of arc size.The height GH scope of the arc size of [2] of part B is 0.4mm～0.8mm in the design.In the design, GH gets 0.6mm.

As shown in Figure 3, the arrow among the figure is represented to be inserted into part B in the components A and is gone, and is inserted in the components A in part B, because be designed with gathering sill at the part B interface; Optical fiber is easy to be inserted into components A, and in the process of part B propulsive element A, [4] part front end of part B is the inclined-plane; Pressurized shrinks, and can push components A, after the propelling; Because [4] part rear end of part B is the plane, and in size [6] part greater than components A, can not move back; Realize that pine does not take off function, [4] part of inside pressure part B just can be separated components A with B energetically.

When needs take off plastic optical fiber, need earlier part B to be pulled outwardly, [2] part of part B promptly withdraws from from [1] of components A, with can part B being unclamped from components A, realizes release, gently draws plastic optical fiber just can plastic optical fiber be taken out from module again.
