    Abstract: The present invention discloses a type of optical fibre connector, comprising: an external shell; an internal shell, installed within said external shell; an inserted core component, contained within said internal shell and comprising an inserted core and a length of optical fibre pre-installed within said inserted core; and a spring, contained within said internal shell and located behind said inserted core, and being for exerting a pre-set axial force on said inserted core. Said internal shell includes a front part and a rear part; said rear part is assembled on said front part. Additionally, said spring is compressed between said rear part and said inserted core. In the present invention, the rear part can act as a retainer for the compressed spring and can also be for securing the Kevlar fibre extension tube of the optical cable. As a result, in comparison to the prior art, the present invention reduces the number of components of the optical fibre connector and simplifies the structure of the optical fibre connector, thus facilitating rapid on-site assembly of the optical fibre connector.

    Abstract: An LC format optical connector (300) for terminating an optical fiber includes a housing (310) configured to mate with an LC receptacle, the housing (310) including a shell (312), a first resilient latch (315) disposed on a surface of the shell (312), and a backbone (316). The LC format connector (300) also includes a collar body (320) disposed in the housing (310) and retained between the outer shell (312) and the backbone (316), wherein the collar body (320) includes a fiber stub (334) disposed in a first portion of the collar body (320). The collar body (320) further includes a mechanical splice (340) disposed in a second portion of the collar body (320), the mechanical splice (340) configured to splice the second end of the fiber stub (334) to a second optical fiber. The resilient latch (315) of the LC format connector (300) further is a single piece latch including a trigger (336) formed thereon.

    Abstract: The present invention discloses an optical fibre connector, comprising: a housing, a ferrule installed within said housing; an end sleeve, connecting to the rear end of said housing; and an optical cable clamp, installed by insertion within said end sleeve, being provided for the purpose of clamping an optical cable. Said optical cable is secured within said optical cable clamp, and after said optical cable clamp is inserted and secured within said end sleeve, the optical fibre of said optical cable is inserted within said housing and butt-joined with the embedded optical fibre within said ferrule. As a result of this, before the butt-joined optical fibres are locked in, the optical cable has already been secured within the optical cable clamp and fixed to the connector housing. Therefore, the butt-joined optical fibres cannot be separated due to the effects of unexpected pulling force, thus ensuring the optical fibre of the optical cable reliably abuts the embedded optical fibre.

    Abstract translation: 本发明公开了一种光纤连接器，包括：壳体，安装在所述壳体内的套圈; 连接到所述壳体的后端的端部套筒; 以及通过插入所述端套中而安装的光缆夹具，用于夹紧光缆。 所述光缆被固定在所述光缆夹内，并且在所述光缆夹被插入并固定在所述端套中之后，所述光缆的光纤被插入所述外壳内并与所述套圈内的嵌入光纤对接 。 其结果是，在对接光纤被锁定之前，光缆已经被固定在光缆夹内并被固定到连接器外壳。 因此，由于意外拉力的作用，对接光纤不能分离，从而保证了光缆的光纤可靠地与埋入光纤相接触。

    Abstract: A device for aligning a first and a second optical fibers each comprising an end mounted into a ferrule (1, 2), comprising:
    - an alignment tube (5) in which the two ferrules are mounted in an interference fit, the two ferrules being opposite and spaced with each other;
    - an optical component (7, 7', 7") that provides for both a non-physical contact and a low optical coupling loss between the first and second fibers, said component being positioned by a spacer (6) substantially at the midpoint between the first fiber (3) and the second fiber (4), such that the image of the end face of the first fiber (3) is coincident with the end face of the second fiber (4).
