Description

一种鼓膜式可重复开启使用的光纤接续子 One kind of reusable open tympanic membrane type using fiber optic splice sub

技术领域 FIELD

[0001] 本发明涉及一种用于光纤安装的连接装置,把插芯总成中V型槽部分密封在鼓膜腔中,使用簧夹抱紧方式驱动鼓膜从而压紧光纤,并可重复开启使用,具体涉及预置光纤或非预置光纤两种接续方式的光纤接续子。 [0001] The present invention relates to a connection device for mounting an optical fiber, the ferrule assembly in the V-groove portion of the seal cavity in the tympanic membrane using a tympanic spring clip hold driven thereby compressing the fibers, use can be repeatedly opened , particularly relates to two kinds of preset or pre-fiber optical fiber connector connecting an optical fiber sub.

背景技术 Background technique

[0002]目前,用于可重复开启使用的快速连接装置产品主要分别采用三种方式固定光纤。 [0002] Currently, for a quick connect repeated opening products are mainly three ways fixed optical fiber.

[0003] 第一种是通过压紧对折的金属片对准固定两根光纤端头实现光纤对接成端的;第二种是通过压紧对合的塑料块固定光纤实现光纤对接成端的;第三种是通过箱砌式压盖搓压浮动块来压紧V型块来固定光纤实现光纤对接成端的。 [0003] The first one is aligned by pressing a metal sheet folded fixing two optical fiber ends to achieve fiber butt end; the second is to achieve fiber end abutting plastic optical fiber block is fixed by pressing together; Third species V-block compression is to build box gland with rubbing by pressing the slider to achieve the fixed optical fiber to the fiber ends abutting. 其中,在对折的金属片、对合的塑料块或浮动块对面的V型块中设用于光纤对接的V型槽;在V型槽的光纤端头连接位置滴入液态物质以提高接续点的光透性;压紧装置的动作是通过压合对折的金属片或对合的塑料块或搓压浮动块来减少V型槽缝隙从而压紧对准光纤来实现两根光纤的对接成端的。 Wherein, in the folded metal sheet, opposite to the V-block or blocks of plastic bonded to the slider in the optical fiber V-shaped groove provided for docking; fiber ends in V-grooves connecting position dropwise liquid substances to increase the splicing point light permeability; pressing operation by means of nip folded sheet metal or plastic bonded to rub or press the slider block to minimize the gap thereby compressing the V-groove fiber alignment to achieve two optical fibers to be butt end .

[0004] 光纤的固定中,第一种光纤固定方式中,金属片对准固定机构中金属片压合时必须在V型槽的对面设置回笼槽,防止光纤压脱,光纤间隙控制靠折合的金属片在型腔中的空间保证开度,即V型槽间隙(穿纤间隙),这些带来了极大地制造难度,成品率低;第二种光纤固定方式中,塑料V型块对准机构在锁紧光纤时,压盖旋转压紧在V型槽中的光纤,由于通过转动压紧方式,受到压盖的间隙漂移影响,光纤受力方向常常会不垂直V型槽,光纤对准精度的误差带来两接续光纤接续损耗加大;塑料V型块对准机构的光纤通道在重复使用时,需要用专用钥匙顶开压块,顶开的开度要求需要有严格的精度要求,产品批量制造难度大,成品率低,而且顶开过程中摩擦产生的塑料碎屑污染接续点,重复使用时影响通光, 造成接续质量下降;有的塑料V型块对准机构初始 [0004] fixing the optical fibers in the first fiber fixing, the sheet metal of the metal sheet alignment fixture means must be provided to return the press when the V-groove opposite the groove, to prevent the pressure off the optical fiber, the optical fiber by controlling the gap folded sheet metal to ensure a space in the cavity opening, i.e. the V-groove gap (gap through fiber), which brings great difficulty to manufacture low yield; fiber fixing the second embodiment, the plastic V-block is aligned when fiber lock mechanism, rotation of the lid is pressed against the V-groove of the optical fiber, since the pressing by rotating manner by the influence of the gap drift gland, often by the fiber direction of the force is not perpendicular to the V-groove fiber alignment error precision brings two optical fiber splice splice loss increase; fiber channel alignment mechanism plastic V-block in repeated use, requires a special key to open the top of the compact, the degree of opening of the top opening request requires strict accuracy requirements, bulk products difficult to manufacture, low yield, and the open top plastic debris contamination generated by friction during splicing point, the influence of light through repeated use, resulting in decreased quality of the connection; plastic V-block some initial alignment mechanism 态为自由态,光纤穿入时需要顶开V型块通道,而其内有匹配液吸附,造成光纤穿入顶开V型槽时,穿纤阻力加大,工程中假对接概率提高,另外锋利的光纤切割端面很容易刮伤V型块,产生碎屑污染接续点,造成接续失败;第三种光纤固定方式中,由于浮动块为门槛式设计,在受到砌盖下压时,浮动块由于塑料变形影响,在转动压纤的同时向下搓动,使V型槽中的光纤产生搓动,光纤受力方向与V 型槽不垂直带来接续光纤的对准精度变差,接续损耗加大,由于对准精度受到材料、配合过盈精度的影响,对准精度离散度大,造成光纤接续的重复性能差。 State to a free state, it is necessary to open the top V-shaped channel block penetrate the fiber, and within which there matching liquid adsorption, resulting in a top opening penetrating the fiber V-groove fiber wear resistance is increased, the probability of false docking engineering increased further sharp cutting end face of the optical fiber V-block is easily scratched, chipping pollution splicing point, resulting in connection failure; optical fiber fixing third embodiment, since the threshold of the slider design, when subjected to the pressure building cover, the slider due to plastic deformation, rubbing down the rotation of the platen while the fiber, the optical fiber V-shaped groove produced rubbing, the fiber direction of the force is not perpendicular to the V-groove splice fiber alignment precision caused deterioration, splice loss increase, since the alignment accuracy by the material of interference with accuracy, alignment accuracy dispersion large, resulting in poor performance of the fiber splice is repeated.

[0005] 前两种光纤固定方式的共同的缺点是V型槽部分不能密封,没有设置匹配夜储存腔,造成V型槽中用于接续用的匹配液容易受到污染和流失,直接影响接续寿命,第三种虽然在工作态可以有一定的封闭作用,但使用前不能密封,而且重复使用时开启的压盖容易滑落,重复使用过程中容易受到环境的污染。 [0005] The common disadvantage of the first two embodiment of the optical fiber fixing V-shaped groove portion can not be sealed, matching night storage chamber is not provided, resulting in the V-groove for connection with the matching liquid susceptible to contamination and loss of life directly affects the connection , while a third can have a role in the closed operational state, but can not be sealed before use, and repeated use of the open lid easy to slide, during repeated use environment susceptible to contamination.

[0018] 与现有技术相比,本发明具有以下优点: [0018] Compared with the prior art, the present invention has the following advantages:

I、本发明光纤接续子的对准固定机构中,两对接光纤的压紧是通过锁紧构件比如簧夹或者套管等简单的零件把箱体和箱盖抱紧在一起,并驱动鼓膜通过减少V型槽和鼓膜之间的空间来压紧V型槽中的光纤来实现压紧的,无论在开启态还是工作压紧态,接续光纤的V 型槽腔体空间都处于密封状态,在光纤接续时无论施工或工作环境如何恶劣,都能保证接续点的洁净,免受污染侵蚀困扰,也不会在重复使用打开压盖时产生的碎屑对接续点的污染,大大提高了光纤接续的成功率,提高了多次重复使用的稳定性,也延长使用寿命,目前, 尚无产品采用此密封方式设计。 I, the present invention is an optical fiber splicing mechanism from the fixed oscillator, two butted optical fibers are pressed by the locking member, such as spring clips or other simple sleeve parts and the cover to hold the casing together and driven by the tympanic membrane reducing the space between the V-groove and the V-groove pressed against the tympanic membrane to achieve compacted fibers, both in the open state or the working state of compression, the fiber V-grooves connecting the cavity space is sealed state, in no matter how poor working conditions or construction, can ensure a clean connection point of the fiber splice, plagued by pollution from erosion, debris will not be generated when the repeated use of the open connection gland contaminated sites, greatly improving the fiber splicing success rate, improve the stability of repeated use, but also extend the life of, at present, there is no way of seal products using this design.

[0019] 2、本发明光纤接续子的对准固定机构中,采用簧夹把箱体和箱盖抱紧在一起,V型槽中的接续光纤所受的压紧力是通过鼓膜传递的,鼓膜的四周均通过浮动筋连接在箱体本体上,所以鼓膜受压后变形始终垂直于V型槽,圆柱状光纤在V型槽中受到3个等分方向均匀压紧力,而无需在V型槽的对面设置回笼槽,防止光纤压脱,克服了现有的受压方式总会对光纤产生一个扭矩的影响,提高了定心精度。 [0019] 2, the present invention is an optical fiber aligning mechanism connecting the sub-fixing, the use of the spring clip hold together the housing and the cover, the pressing force of the V-groove of the optical fiber connection suffered transmitted through the tympanic membrane, four weeks tympanic membrane are connected by the floating rib in the case body, so after the compressive deformation is always perpendicular to the tympanic membrane V-groove, the optical fiber subjected to a uniform cylindrical pressing forces three aliquots directions in a V-groove, without having V shaped groove disposed opposite the return channel, to prevent the pressure off the optical fiber, to overcome the influence of the pressure receiving conventional manner always produce a torque on the fiber, to improve the centering accuracy.

[0020] 3、本发明光纤接续子固紧力动作时平稳,V型槽中的接续光纤不会由于搓动产生偏心和错位,而且压紧时的变形均匀,保证两对接光纤获得同等的压紧力,实现可靠对接。 [0020] 3, when the optical fiber of the present invention is smooth connecting operation of the sub-tightening force, the V-groove of the optical fiber connection is not due to the rubbing and the eccentric dislocation, and uniform deformation during pressing, ensure that the two butted optical fibers receive the same pressure clamping force, reliable docking.

[0021] 4、本发明光纤接续子由于箱盖的顶开仅仅是用来取消加在鼓膜上的压紧力,只需要挤开箱盖,使鼓膜恢复自由态即可,其开度要求没有太大的精度要求,降低了制造难度, 有利于大批量生产。 [0021] 4, the present invention is an optical fiber splicing sub-top lid opening due only to cancel the applied pressing force on the eardrum, the lid need only squeeze the tympanic membrane to restore a free state, which requires no opening too much precision, reducing manufacturing difficulty, is conducive to mass production.

[0022] 5、本发明光纤接续子采用浮动的鼓膜,非工作态时(即穿纤时)鼓膜为自由开启状态,与插芯总成中的V型体槽之间形成一个打开的光纤通道,穿纤进入V型槽时不需要先顶开压块,这样穿纤难度大大降低,而且减少了锋利的光纤切割面在穿纤时对V型槽的损伤, 减少了穿纤污染,提高了接续成功率。 [0022] 5, the present invention is an optical fiber splice sub floating tympanic membrane, while the non-operating state (i.e., when wearing fiber) consisting of an open state of the tympanic membrane, forming an open passage between the optical fiber ferrule assembly in the body of the V-groove , wear-fiber V-grooves do not need to enter the open top of the compact, so that wear is greatly reduced fiber difficulty, but also reduces the sharp cutting surface of the optical fiber when wear damage to the V-groove, reducing wear fiber pollution and improve connection success rate.

[0023] 6、本发明光纤接续子箱体两端分别设置有匹配液腔,多次重复使用时能有充足的匹配液保证多次接续的质量,防止匹配液流失;同时光纤穿入口处冗余的匹配液能够封闭接续点与外部环境,提高接续点匹配液的抗污能力,提高了使用寿命。 [0023] 6, the present invention is an optical fiber splicing cabinet ends are respectively provided with a sub-matching liquid chamber, to ensure adequate matching liquid mass successive times, to prevent loss of matching liquid when repeatedly used; while redundant fiber through the entrance I was able to close the match point and the external environment continue to improve the connection point matching liquid dirt immunity, improve the service life.

[0024] 7、本发明光纤接续子的V型槽体的前连接腔中镶接的插芯中心与V型槽固定的光纤中心同心度高,接续精度高,而且受环境温度变化影响小,接续损耗变化小。 [0024] 7, the present invention is an optical fiber splice fixed concentric high center of the fiber before the sub-chamber is connected to the V-groove in the insert member into contact with the V-groove the center of the ferrule, the connection precision is high, but also by the ambient temperature change is small, splice loss is small change.

[0025] 8、本发明的鼓膜厚度薄,为原色塑料材料,相对于不透明的对折金属或厚重的塑料压盖,其透光性能更好,有利于接续完成后,在光纤中导入红外光来通过壳体上的开启槽观察接续点的接续质量,不受环境光干扰。 [0025] 8, the present invention thin eardrum, primary color plastic material, folded with respect to the opaque metal or heavy plastic lid, which better light transmission properties, facilitate completion of the connection, the infrared light introduced in the optical fiber splicing point viewed through the housing opening groove connection quality, interference from ambient light.

[0026] 9、本发明的光纤接续子成端后,光纤在接续子中预留有冗余光纤尾弯,在接续光缆受外力拉拽变形时,冗余的光纤尾弯可以保护光纤一定程度上不被拉断,提高了产品的适应范围,尤其适用于质次光缆。 [0026] 9, the optical fiber of the present invention into the connection end of the sub, the sub-connecting fiber in the reserve redundant fiber tail bending, when the connection cable is pulled deformed by external force, the end of the optical fiber redundant protection fiber may be bent to a certain extent on not pulled off, improved to adapt to a range of products, especially for cable quality time.
