技术领域 FIELD

[0001]本发明涉及光纤连接装置,尤其涉及一种具有一体式外壳的光纤接入插头。 [0001] The present invention relates to optical fiber connector, and particularly to fiber access plug having a one-piece housing.

背景技术 Background technique

[0002]光纤通信已成为现代通信的主要支柱之一,在现代电信网中起着举足轻重的作用,网络科技的发展,使光纤作为一种高速、宽带数据通信的传输媒介得到了日益广泛的使用。 [0002] optical fiber communication has become one of the main pillars of modern communications, plays an important role in modern telecommunication networks, development of network technology, the optical fiber as a high-speed, broadband data communications transmission medium has been increasingly widely used . 光纤连接器是光纤与光纤之间进行可拆卸(活动)连接的器件,它把光纤的两个端面精密地对接起来,以使发射光纤输出的光能量能最大限度地耦合到接收光纤中去,并使由于其介入光链路而对系统造成的影响减到最小。 The fiber optic connector device is removably carried out (active) connection between the optical fiber and the optical fiber, which end faces of the two optical fibers accurately docking so that the light energy emitted to maximize the optical output is coupled into the receiving fiber to, Because of its involvement and influence of the optical link and to minimize impact on the system. 目前常用的光纤连接器按连接头结构形式可分为:FC、SC、ST、LC、D4、DIN、MU、MT 等各种形式。 The currently used optical fiber connector according to connector structure can be divided into: various forms of FC, SC, ST, LC, D4, DIN, MU, MT and the like.

[0003] FC型光纤连接器最早是由日本NTT研制,其外部加强方式是采用金属套,紧固方式为螺丝扣。 [0003] FC-type optical fiber connector was first developed by NTT in Japan, which is a way to strengthen the outer metal sleeve, fastening means for the turnbuckle.

[0004] SC型光纤连接器其外壳呈矩形,所采用的插针与耦合套筒的结构尺寸与FC型完全相同,紧固方式是采用插拔销闩式。 [0004] SC-type optical fiber connector housing which is rectangular, frame size employed pin coupling sleeve and FC type identical fastening bolt is a plug-type pin.

[0005] ST连接器与SC型光纤连接器的区别在于ST连接器的芯外露,SC连接器的芯在接头里面。 [0005] The difference between the ST connector SC-type optical connector comprising a ferrule ST connectors, SC connectors in the connector inside the core.

[0006] LC型连接器是著名Bell(贝尔)研究所研究开发出来的,采用操作方便的模块化插孔(RJ)闩锁机理制成。 [0006] LC-type connector is known Bell (Bell) Research Institute developed, made easy to operate using the modular jack (RJ) of the latch mechanism. 其所采用的插针和套筒的尺寸是普通SC、FC等所用尺寸的一半,为 Pin and sleeve size of their use of ordinary SC, FC, etc. half the size used for

1.25mm,其相应的接口端面尺寸为4.5mm X 4.5mm,可以提高光纤配线架中光纤连接器的密度。 1.25mm, which end faces of respective interfaces dimensions 4.5mm X 4.5mm, can increase the density of optical fiber connectors in patch panels. 目前,在单模SFF方面,LC类型的连接器实际已经占据了主导地位,在多模方面的应用也增长迅速。 Currently, in terms of single-mode SFF, LC connector types actually have dominated the application in terms of multi-mode is also growing rapidly.

[0007] MUCMiniature Unit Coupling)连接器是以目前使用最多的SC型连接器为基础,由NTT研制开发出来的目前世界上最小的单芯光纤连接器。 [0007] MUCMiniature Unit Coupling) connector is currently the most used SC connectors based on research developed by NTT is currently the world's smallest single-core optical fiber connector. 该连接器采用1.25mm直径的铝管和自保持机构,其优势在于能实现高密度安装,但其接口端面尺寸依然达到了6.5mm X4.4mm0 The aluminum tube connector 1.25mm diameter and a self-holding mechanism, the advantage that high-density mounting can be achieved, but it still reached the interface end dimensions 6.5mm X4.4mm0

[0008] 随着FTTH(Fiber To The Home,光纤到家)的大规模推进,光纤网络向更大带宽、更大容量的方向迅速发展,光接入网中光纤交接的数量需求愈来愈多,对相应硬件设备的交接容量需求也越来越大,要求光纤连接器的安装密度越来越高,相应的体积越来越小,尤其是要求光纤连接器接口端面的横向尺寸尽可能地缩小,以实现在现有设备物理容积不变的基础上,提高光纤连接器的安装密度,但上述现有的光纤连接器的结构和装配工艺均无法胜任这种需求。 [0008] As the FTTH (Fiber To The Home, fiber to the home) is promoting large-scale, rapid development of fiber-optic network in the direction of greater bandwidth, greater capacity, the number of optical fibers in optical access network handover demand more and more, transfer capacity requirements for the corresponding hardware device is also increasing, the mounting density fiber optic connector requires increasingly high, the corresponding smaller and smaller, the transverse dimension of the interface requirements of a particular end surface of the optical fiber connector as small as possible, in order to achieve the same existing facilities on a physical volume, density mounting optical fiber connectors, but the structure and assembly process of the above-described conventional optical fiber connectors are not capable of this demand.

[0009]同时,现有的光纤连接器的外部壳体一般分为两部分,例如,SC分为内外框套,LC分为前后壳,两部分结构的外壳在制造的过程比较复杂,安装时需要的过程也比较繁杂,且由两部分组成的光纤连接器外壳之间通常是通过卡扣来固定连接的,多次的插拔可能造成连接强度降低,是两者之间的连接不牢固,影响产品的正常使用,只能更换新的产品,在造成浪费的同时,使制造和使用成本提高。 When [0009] Meanwhile, the external housing of a conventional optical connector is generally divided into two portions, e.g., SC and external box is divided into sets, the LC is divided into front and rear shells, two-part housing structure in the manufacturing process is complicated, installation process requires relatively complicated, and between the optical fiber connector housing consists of two parts is generally fixed by a snap connection, many of the plug connector may result in reduced strength, the connection between the two weak, affect the normal use of the product can only be replaced with new products, while wasteful, and the manufacturing cost increase.
