Description
[technical field]
The utility model is about a kind of optical fiber holding unit, particularly has the optic fibre guide ditch and assembles the optical fiber holding unit in fibre bundle zone about a kind of.
[background technology]
Fibre circuit is the important component part of optical fiber telecommunications system, usually can be provided with along certain path, and the material because of optical fiber mostly is quartz glass etc. again, has that diameter is little, a poor toughness and be easy to characteristics such as cracked, needs fix optical fiber along fiber path.
Be used to twine the traditional electric wire holder of the many employings of optical fiber holder of optical fiber in existing optical device, the module, but, this kind holder generally adopts plastic material and is fixed in base with double faced adhesive tape, there are shortcomings such as intensity not high and serviceable life is short in it, explains inadequate for reaching the optical module device more than 20 years average life.
Prior art is and for example shown in Figure 1, is the anti-fixed sturcture 1 of opening of optical cable that the TaiWan, China patent announcement is disclosed for No. 311696.The anti-structure 1 of opening of this optical cable comprises a base 11, a slide block 12, a sliding members 13 and a flat head screw 14.Wherein, this slide block 12 is arranged on this base 11, and match with the upper surface of this slide block 12 in the lower surface of this sliding members 13, and the upper surface of this sliding members 13 is provided with center pit and a plurality of storage tank 131.This storage tank 131 can ccontaining optical cable 15, and is locked by this flat head screw 14.Simultaneously, the position-adjustable of this sliding members 13, straight to keep optical cable.
The anti-structure 1 of the optical cable that above-mentioned patent disclosed can realize the purpose of optical cable fixing, but, because it is to utilize 14 pairs of optical cables 15 of flat head screw to be locked, in the process of these flat head screw 14 lockings, might be excessive and cause the flexural deformation of optical cable 15 inner fibers to optical cable 15 application of forces, and then influence optic fibre characteristic; If 14 pairs of optical cable 15 application of forces of this flat head screw are too small, then optical cable 15 may be not tight because of fixing, causes easily to come off.
And the anti-structure 1 of opening of the optical cable that this patent disclosed is made comparatively complexity, and its main element such as base 11 and sliding members 13 need be finished operations such as perforate, fluting in manufacture process.Simultaneously, this sliding members 13 is slidingly matched with these base 11 top shoes 12, also needs higher manufacturing accuracy.And anti-1 the optical cable quantity that can fix of structure of opening of this optical cable is comparatively limited, needs to decide according to the quantity of storage tank 131 on the sliding members 13, is difficult to satisfy the parallel needs that are provided with of many optical cables.
[summary of the invention]
The purpose of this utility model be to provide a kind of processing procedure simply, the optical fiber holding unit of fixing optical fiber easily and effectively.
For realizing the utility model purpose, the utility model optical fiber holding unit comprises a retaining component and a base.This retaining component is made by an elastic sheet metal punching press, and includes optic fibre guide ditch and the zone of assembling fibre bundle; This base can be single punch elements, also can be the part of communicator housing.This retaining component cooperates with base, and can utilize the width of this retaining component guiding ditch to have flexible characteristics near fibre diameter and optical fiber, prevents that optical fiber from coming off after making optical fiber place the center aggregation zone of this retaining component, reaches the effect to the optical fiber fixing.
Compared with prior art, the utlity model has following advantage: because of the utility model optical fiber holding unit adopts the punching press product, processing procedure is simple, and the fibre bundle aggregation zone that retaining component had can be accommodated multifiber, and can avoid optical fiber by ejecting in it, be easy to realize fixing, and have higher-strength and life-span optical fiber.

[embodiment]
As shown in Figure 2, the utility model optical fiber holding unit 2 comprises a retaining component 3 and a base 4, and this retaining component 3 can be fastened on this base 4.Wherein, this retaining component 3 is to make and form a body 31 with the metal sheet integrated punching, be respectively equipped with a swash plate 38 outside from these body 31 opposite ends, optic fibre guide ditch 36 is formed at body 31 and runs through outer the swash plate 38 that extends to its two ends, and outer open that formed optical fiber boundling hole 35 is communicated with on swash plate 38 with this, this optic fibre guide ditch 36 and two relative optical fiber boundling holes 35 can be in order to fixing fibre bundle (not shown).Body 31 other two opposite sides integrated punchings from this retaining component 3 form elastic fixed part 32 respectively, and this elastic fixed part 32 comprises that further two relative fixing arms 33 and fix pin 34, and this fixes and forms a gap 37 between pin 34 and the fixing arm 33.
As shown in Figure 3, retaining component 3 is installed on this base 4, wherein, base 4 can be the part that single element also can be the specific communication devices housing, when retaining component 3 adapting devices are on base 4, can inwardly push elastic fixed part 32 makes fixing pin 34 pass square opening 41 corresponding on the base 4, after waiting to fix pin 34 and passing this square opening 41, remove pressing force, the then thickness of slab of gap 37 ccontaining bases 4, fixing arm 33 is against base 4, so that this retaining component 3 is fixed in this base 4 simultaneously.
As shown in Figure 4, after retaining component 3 is fixed in base 4, some fibre bundles 5 can be in regular turn in optic fibre guide ditch 36 be packed retaining component 3 into, fibre bundle 5 is packed into behind the retaining component 3, because the outer swash plate 38 of opening is tiltedly opened to the outside from body 31, fibre bundle 5 is fastened in the optical fiber boundling hole 35, because optic fibre guide ditch 36 width approach fibre diameter, and that fibre bundle 5 itself is had is flexible, can not eject after can making fibre bundle 5 insert this optical fiber boundling hole 35.
