Abstract
The invention discloses a fiber movable connector pin, comprising a core body and a tail handle. The core body is a cylinder with the center provided with a micropore; the tail handle comprises a handle body and a bearing located at a front end of the handle body, wherein the bearing is in crimp connection with a rear end of the core body in an interference fit mode; the center of the handle body is provided with an inner hole used for a fiber to penetrate and running through the micropore of the core body. A rear end of the handle body is provided with an extension segment; an initial position of the extension segment is provided with a guide hole vertically penetrating the inner hole.
Description
Technical field
The present invention relates to and a kind ofly will carry out the device be actively coupled between optical fiber and optical fiber, be specifically related to a kind of fiber active linker, especially fiber-optical movable connector pin.
Background technology
As shown in Figure 1, fiber-optical movable connector pin (hereinafter referred to as contact pin) is divided into two parts, a part is the right cylinder of precise centering in optical fiber connector plug, there is a micropore 101 at center, as optical fiber align (being commonly called as lock pin body 100), another part is caudal peduncle 200, is crimped on ceramic body, as fixed fiber by interference wringing fit.
Traditional contact pin length only has 8mm, and diameter of bore is 1mm, and when being filled with glue 20 in endoporus 203, and connect when being penetrated in caudal peduncle endoporus by the optical fiber 10 of 0.9mm diameter, glue 20 can overflow from caudal peduncle.What this glue used is all 353ND glue, after being heating and curing glue can vitreous, hardness higher, and more fragile with the optical fiber of glue-contact, easily impaired when optical fiber is bent, be particularly very easy to disconnected fine with position, glue boundary 11.
Summary of the invention
For this reason, technical matters to be solved by this invention is to provide a kind of fiber-optical movable connector pin preventing fibercuts, to overcome the deficiency that prior art exists.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of fiber-optical movable connector pin, comprise lock pin body and caudal peduncle, there is centered by described lock pin body the right cylinder of micropore, described caudal peduncle comprises handle body and is positioned at the bearing of handle body front end, described bearing interference fit is crimped on lock pin body rear end, described Bing Ti center has facial expression fibre and penetrates and penetrate into the endoporus of the micropore of lock pin body, and it is characterized in that: described handle body has extension in rear end, described extension reference position is provided with the guide hole vertically passing into endoporus.
Described guide hole has two, is relatively located at above and below endoporus respectively.
Described guide hole is the hydraucone of big upper and lower small mouth.
Adopt technique scheme, the present invention in use, after insertion optical fiber, in the handle body in guide hole front, only inject the glue being used for fixed fiber, unnecessary glue can ooze out from guide hole and solidify, and between the endoporus of extension and optical fiber, do not need to inject glue, optical fiber can fine motion in the endoporus of extension, has the following advantages like this:
1, unnecessary glue can be guided by guide hole by contact pin, helps to check whether glue quantity and solidification effect meet technological requirement simultaneously;
2, the square optical fiber at guide hole rear section of being extended when bending stops, larger bending stress can not be concentrated on glue curing point and effectively can prevent fibercuts.
Therefore, fiber-optical movable connector pin of the present invention has the advantage preventing fibercuts.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described in detail with concrete enforcement:
Fig. 1 is the structural representation of prior art;
Fig. 2 is structural representation of the present invention;
In figure:
100-lock pin body, 101-micropore, 200-caudal peduncle, 201-handle body, 202-bearing, 203-endoporus, 300-extension, 400-guide hole, 10-optical fiber, 20-glue.
Embodiment
As shown in Figure 2, fiber-optical movable connector pin of the present invention, comprises lock pin body 100 and caudal peduncle 200.
Have the right cylinder of micropore 101 centered by lock pin body 100, caudal peduncle 200 comprises handle body 201 and is positioned at the bearing 202 of handle body 202 front end.Bearing 202 interference fit is crimped on the rear end of lock pin body 100, and Bing Ti 100 center has the endoporus 203 that facial expression fibre 10 penetrates, and this endoporus 203 penetrates into the micropore 101 of lock pin body 100 always.
In the present invention, lock pin body 100 has the extension 300 relative to prior art, and the length of such as original contact pin is 8mm, and it is 12.6mm that lock pin body 100 increases the overall length after extension 300.Be provided with two guide holes 400 vertically passing into endoporus in extension 300 reference position (i.e. the position of contact pin length 8), this guide hole 400 is oppositely arranged on above and below endoporus 203.For the guide hole of top, guide hole 400 is the hydraucone of big upper and lower small mouth.
It is exactly more than fiber-optical movable connector pin of the present invention, in use, after insertion optical fiber, in the handle body in guide hole front, only inject the glue being used for fixed fiber, unnecessary glue can ooze out from guide hole and solidify, and between the endoporus of extension and optical fiber, do not need to inject glue, optical fiber can fine motion in the endoporus of extension, has the following advantages like this:
1, unnecessary glue can be guided by guide hole by contact pin, helps to check whether glue quantity and solidification effect meet technological requirement simultaneously;
2, the square optical fiber at guide hole rear section of being extended when bending stops, larger bending stress can not be concentrated on glue curing point and effectively can prevent fibercuts.
Therefore, fiber-optical movable connector pin of the present invention has the advantage preventing fibercuts.
