Description
[technical field]
The utility model is about a kind of fibre-optical fixator, especially refers to a kind of fibre-optical fixator that can prevent the optical fiber overbend.
[background technology]
Optical fiber be the optical communication networking important composition partly, but fibre-optical fixator fixing optical fiber, optical cable in placement of route and installation end with constraint and arrangement optical fiber.Common fibre-optical fixator fixed fiber is at ad-hoc location, when optical fiber installation end change in location, then optical fiber may produce bending, and optical fiber mostly is materials such as quartz glass, fragile and cracked easily, the undue bending of optical fiber will cause a large amount of optical signals fibre cores to leak to optical fiber and produce bigger bending loss outward, even cause fibercuts.So fibre-optical fixator needs in effective fixing optical fiber, the overbend that prevents optical fiber is to guarantee the signal normal transmission.
Existing fibre-optical fixator mostly is traditional electric wire or cable retainer, as United States Patent (USP) the 5th, 149, disclosed a kind of insertion buckle-type holder that is installed on the substrate for No. 027, comprise a cover plate and a plurality of installation foot, this installation foot is snapped on the substrate, and cable passes and is fixed in the formed space of installation foot, cover plate and substrate, and each installation foot comprises that further a plurality of locating pieces are used to adjust height the fixing with cooperation different size cable between cover plate and the substrate.Though this fixator is the cable of varying number, specification fixedly, but do not prevent the device of optical fiber overbend, therefore be only applicable to general electric wire, for optical fiber, optical fiber is subjected to external force and when crooked, may cause a large amount of loss of signal because of the optical fiber overbend, even optical fiber is cracked.
Another kind of optical fiber holder sees also United States Patent (USP) the 5th, 530, and No. 785, the optical fiber holder of its announcement is made up of two retaining components, substrate and latching system.These two retaining components further comprise a retaining element and sliding members, it includes a half-cylindrical holding parts and a tabular installation portion, optical fiber is fixed in the formed space of two holding parts, the installation portion of this retaining element is fixed on the substrate, the installation portion of this sliding members can slide along the chute of substrate, to adapt to the optical fiber of different size, this locked instrument can be fixed this sliding members with the spacing of adjusting sliding members and retaining element.Though the optical fiber of this optical fiber holder energy fixing various outer diameter, also design prevents the device of optical fiber overbend, so still can not ensure normal optical signal transmission.
In view of this, provide a kind of and can prevent that the fibre-optical fixator of optical fiber overbend is very necessary.
[summary of the invention]
The purpose of this utility model is to provide a kind of fibre-optical fixator that prevents the optical fiber overbend, thereby ensures the normal transmission of light signal in the optical fiber.
The purpose of this utility model is achieved in that provides a fibre-optical fixator, is installed in the rectangular opening of base plate, comprises an accommodation structure and installing mechanism.Wherein, this accommodation structure further comprises a top board and two side, and extend relatively downwards from the two ends of top board this two side, all inwardly arrange a spring bearer plate on it, and two outer ledges of this top board all extends outward a bend arm.This installing mechanism further comprises and fixes pin and registration arm, and this fibre-optical fixator fixes pin and registration arm clamping base plate in the centre by this, thereby fibre-optical fixator is installed to base plate.
Compare with existing fibre-optical fixator, the utlity model has following advantage: the degree of crook that the bend arm that this fibre-optical fixator had can limit fibre, thereby prevent because a large amount of bending losss of causing of optical fiber overbend, ensure the stable transfer of light signal in the optical fiber.
[description of drawings]
Fig. 1 is the three-dimensional exploded view of the utility model fibre-optical fixator and base plate.
Fig. 2 is the stereographic map behind the utility model fibre-optical fixator fixing optical fiber.
[embodiment]
Seeing also Fig. 1, is the three-dimensional exploded view of the utility model fibre-optical fixator and base plate.This fibre-optical fixator 1 is used for up-winding fiber or optical cable, and is installed on the base plate 2.This base plate 2 can adopt traditional mechanical method fixation in photoelectric communication equipment, also can be the some of photoelectric communication apparatus casing.
This fibre-optical fixator 1 comprises an accommodation structure 11 and an installing mechanism that links to each other with accommodation structure 12, it can be by metal or integrally moulded, wherein this accommodation structure 11 is used for fixing optical fiber 3 (please refer to Fig. 2), it further comprises a top board 111 and two side 112, this two side 112 is to extend relatively downwards from the two ends of top board 111, all inwardly arrange a spring bearer plate 113 on it, the stiff end of this spring bearer plate 113 is connected with two side 112 respectively, the free end of spring bearer plate 113 is respectively to two side 112 inboard extensions, be used for fixing optical fiber 3 in accommodation structure 11, and two outer ledges of this top board 111 all outwards and to top board 111 tops extend a bend arm 114, with the limit fibre degree of crook, prevent the optical fiber overbend.This installing mechanism 12 is match with base plate 2 (detailed aftermentioneds), thereby this fibre-optical fixator 1 is installed in photoelectric communication equipment, it comprises that further two rectangles fix pin 121 and four registration arm 122, it is to stretch out from sidewall 112 lower end levels to form that this rectangle fixes pin 121, and this registration arm 122 also is that 112 outer ledges stretch out and form from the two side.
Arrange the rectangular opening 21 of two symmetries on this base plate 2, two spacings that fix pin 121 inner side edges equate under the distance of two outer side edges 211 of this two rectangular opening 21 and the fibre-optical fixator 1 no external force effect, and the physical dimension of this two rectangular opening 21 all fixes the transversal section of pin 121 greater than each.
Please consult Fig. 2 simultaneously, during assembling, elder generation's up-winding fiber 3 is in accommodation structure 11, inwardly push the two side 112 of fibre-optical fixator 1 again, to dwindle the spacing of two fixing pin 121, thereby making two of fibre-optical fixator 1 fix pin 121 can be passed down through corresponding rectangular opening 21 and enter base plate 2 belows, after removing external force, the pitch enlargement of this two fixings pin 121, the two side 112 of fibre-optical fixator 1 is supported the outer side edges 211 that is attached to rectangular opening 21 respectively, two fix the downside that pin 121 insert base plates 2, and registration arm 122 is supported on the base plate 2, its with fix pin 121 actings in conjunction this fibre-optical fixator 1 be fixed in base plate 2.Be appreciated that this fibre-optical fixator 1 is also quite easy from the unloading process on the base plate 2.
The utility model fibre-optical fixator 1 fixing optical fiber 3 is in accommodation structure 11 and base plate 2 formed spaces, the free end of two spring bearer plates 113 inwardly draws in to be pressed on the optical fiber 3, because this two spring bearer plate 113 has the elastic deformability, make fibre-optical fixator 1 can the fixing varying number, the optical fiber 3 of specification.And, angle of bend that the bend arm 114 at these fibre-optical fixator 1 two ends can limit fibre 3 and crooked radius-of-curvature, thus prevent because a large amount of bending losss that optical fiber 3 overbends cause.But the position of bend arm 114 described in the utility model is not limited in the outer ledge of top board 111, as the outer ledge that is arranged in two side 112 also has identical effect.
