Abstract

The utility model provides a plastic fiber locking device, which is composed of three parts of a photoelectric conversion device or an electro-optics conversion part (1), a cone (2) and a cylinder (3). The effect of the part (1) is to realize photoelectric or electro-optics conversion; the effect of the part (2) is to fix and connect a plastic fiber (5); and the effect of the part (3) is to guide and compact the part (2) on the plastic fiber to realize fixing the part (5). The fixing method of the plastic fiber locking device is that when the part (5) is inserted into the part (3), because a guide groove is arranged at an interface part of the part (3), the part (5) is easily inserted into the part (3) and is connected into the part (2); the part (3) is pushed into the part (2); because the part (2) is an open-ended cone, under the extrusion of an open-ended piece by the cone of the part (3), the part (5) is firmly grasped; and thus the effect of fixing the part (5) is achieved. During the usage process, because of the extrusion of the part (2) by the part (3), the plastic fiber (5) is firmly fixed in the plastic fiber locking device; and the functions of fixing and connection between the plastic fiber and a plastic optical module are realized. When the plastic fiber is needed to be removed, the part (3) is needed to be withdrawn; the extruding force of the part (3) on the part (2) disappears; the part (2) has no grip power on the part (5); and the plastic fiber can be easily removed out of the plastic fiber locking device (4).

Description

A kind of plastic optical fiber locking device

Technical field

The utility model belongs to the active photoelectric device class of plastic optical fiber communication products, and it relates to the fixing means that single-shot, single receipts or transceiving integrated module and optical fiber are provided.

Background technology

Along with people's is to attaching 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.In order to solve the access difficult problem of " last hundreds of rice ", researcher has found the substitute of copper cash and silica fibre finally, and it is exactly the access difficult problem preferred plan that solves " last hundreds of rice " that plastic optical fiber, it and silica fibre are used.But, because plastic optical fiber do not use the special light connector on the glass optical fiber, and directly use plastic optical fiber to be connected with the plastics optical module, this will have special device to realize fixing and be connected plastic optical fiber with regard to requiring the plastics optical module.

Summary of the invention:

In order to reach the locking between plastic optical fiber and the plastics optical module, the utility model provides a kind of effectively fixing and locking that is connected between plastic optical fiber and the plastics optical module that realizes.

To achieve these goals, theing contents are as follows of the utility model:

A kind of plastic optical fiber stationary installation [4] that the utility model provides is by a photoelectric conversion device or electric light converting member [1], a cone [2], and 3 parts such as a right cylinder [3] are formed, and its structured flowchart is as shown in Figure 1.Wherein, the effect of parts [1] is to realize photoelectricity or electric light conversion; The effect of parts [2] is fixing and is connected plastic optical fiber [5]; The effect of parts [3] is that plastic optical fiber is led and compacting part [2] realization fixed part [5].

Described light-receiving member [1] is a kind of optical communication optical device commonly used;

The sectional view of described light-receiving member [2] is as shown in Figure 2; It is a kind of parts that adopt the ectosome circular cone endoporus cylinder that polymeric material processes; The circular cone of this parts front end face AC is the opening of three lobe shapes; Rear end face AA be diameter than little the remaining silent of front end, the bore dia AB on the rear end face is bigger slightly than the diameter of optical fiber.The outside drawing of light-receiving member [2] is as shown in Figure 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 sectional view of described parts [3] is as shown in Figure 4, and it is the parts of remaining silent that a kind of polymeric material is formed ectosome cylinder endoporus circular cone; The size of the end face BA of parts [3], BB, BC need be complementary with the ectosome circular cone size of light-receiving member [2] and the diameter of optical fiber; Just can be assembled into light-receiving member [2] among light-receiving member [3] the endoporus circular cone, form cross-section structure as shown in Figure 5.

Described parts [5] are by plastic optical fiber, and its effect is that light is imported into parts 1 or the light of parts 1 is spread out of.Formed assembly drawing is as shown in Figure 6 in parts [5] the insertion plastic optical fiber stationary installations [4].

Embodiment

A kind of plastic optical fiber stationary installation that the utility model provides and the embodiment of fixing means will combine accompanying drawing to further specify as follows:

As shown in Figure 6, be inserted in the parts [2] through parts [3] at parts [5], because be designed with gathering sill at parts [3] interface, parts [5] are easy to be inserted into parts [3], just are easy to be inserted in the parts [2] through parts [3] again, realize the coupling of light path.Parts [3] are shifted onto in the parts [2], because parts [2] are the circular cones of opening, the lobe of opening is under the extruding of the circular cone of remaining silent of parts [3] again; Hatch bore diameter AC with the parts [2] of opening; The internal diameter of parts [2] is shunk, the parts [5] of firmly holding with a firm grip, thus reach the effect of fixed part [5].In use, because parts [3] are to the extruding of parts [2], parts [5] are securely fixed in the fibre lock, have realized fixing and be connected coupling function between plastic optical fiber and the plastics optical module.

When needs take off plastic optical fiber; As long as earlier parts [3] are withdrawed from from parts [2], parts this moment [3] disappear to parts [2] extruding force, and the internal diameter of parts [2] recovers life size; Like this parts [5] have not been had grip, plastic optical fiber just can take out from plastic optical fiber stationary installation [4] like a cork.

As shown in Figure 2, when the design of the endoporus AB of parts [2],, generally design more a little louder a little than the external diameter of plastic optical fiber to size AB in order to reach the plug function easily of plastic optical fiber.When the configuration design of light parts [2], designing; In order to realize locking and unlocking function to optical fiber, be the opening of three lobes with the Front-end Design of parts [2], parts [2] have spring function like this; Under parts 3 effects; Can be to parts [5] the locking and unlocking and since three lobes design, can guarantee the center of plastic optical fiber simultaneously in the hole.

In the utility model, parts [2] AB is designed and sized to 1.0mm～2.3mm, AA size design 2mm～4mm, and AC is designed and sized to 1.5mm～3mm.

As shown in Figure 4, parts [3] are the parts of remaining silent of ectosome cylinder endoporus circular cone, and for cooperating of the size AC that guarantees light parts [3] and parts [2], the size BA of parts [3] is 1.8mm～3.8mm, and BB is 1.4mm～3mm, and BC is 2.2mm～5mm.

In the utility model, when using diameter, consider that the AB size design of parts [2] need be greater than the diameter of optical fiber, so get the 2.25mm of AB, AA size 4mm, AC size 3mm as the optical fiber of 2.2mm.For cooperating of the size AC that guarantees light parts [3] and parts [2], the size BA of parts [3] is 3.8mm, and BB is 3.0mm, and BC is 5mm.

In the utility model, when using diameter, consider that the AB size design of parts [2] need be greater than the diameter of optical fiber, so get the 1.05mm of AB, AA size 4mm, AC size 3mm as the optical fiber of 1.0mm.For cooperating of the size AC that guarantees light parts [3] and parts [2], the size BA of parts [3] is 3.8mm, and BB is 3.0mm, and BC is 5mm.
