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 a kind of by the device being actively coupled between optical fiber and optical fiber and in particular to a kind of optical fibre
Adapter, 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 that optical fiber connects
The cylinder of precise centering in device plug, there is a micropore 101 at center, as optical fiber align (being commonly called as lock pin body 100), another portion
It is divided into caudal peduncle 200, is crimped on ceramic body by interference tight fit, as fixing optical fiber.
Traditional contact pin length only has 8mm, and diameter of bore is 1mm, when being filled with glue 20 in endoporus 203, and connect by
When the optical fiber 10 of 0.9mm diameter penetrates in caudal peduncle endoporus, glue 20 can overflow from caudal peduncle.That this glue uses is all 353nd
Glue, after being heating and curing, glue meeting vitreous, hardness are higher, and compare fragile with the optical fiber of glue-contact, when optical fiber is bent
Easily impaired, particularly it is very easy to disconnected fibre with glue boundary position 11.
Content of the invention
For this reason, the technical problem to be solved is to provide a kind of fiber active linker preventing fibercuts to insert
Pin, to overcome the shortcomings of prior art presence.
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that:
A kind of fiber-optical movable connector pin, including lock pin body and caudal peduncle, has micropore centered on described lock pin body
Cylinder, the bearing that described caudal peduncle includes shank body and is located at front end of the shank body, described bearing interference fit is crimped on lock pin body
Rear end, described shank body center have facial expression fibre penetrate and penetrate into lock pin body micropore endoporus it is characterised in that: described handle
Body has extension in rear end, and described extension original position is provided with the guide hole being vertically passed through endoporus.
Described guide hole has two, respectively oppositely above and below endoporus.
Described guide hole is the horn mouth of big upper and lower small mouth.
Using technique scheme, the present invention, when using, after insertion optical fiber, only notes into the shank body in front of guide hole
Enter the glue for fixing optical fiber, unnecessary glue can ooze out from guide hole and solidify, and the endoporus of extension and optical fiber it
Between do not need inject glue, optical fiber can fine motion in the endoporus of extension, so have the following advantages:
1st, unnecessary glue can be guided by contact pin by guide hole, help check glue quantity and solidification effect simultaneously
Whether fruit meets technological requirement；
2nd, the square optical fiber at guide hole rear is extended section when bending and stops, will not concentrate larger bending stress
Fibercuts can effectively be prevented in glue curing point.
Therefore, the fiber-optical movable connector pin of the present invention has the advantages that to prevent fibercuts.
Brief description
Below in conjunction with the accompanying drawings and be embodied as that the present invention is described in detail:
Fig. 1 is the structural representation of prior art；
Fig. 2 is the structural representation of the present invention；
In figure:
100- lock pin body, 101- micropore, 200- caudal peduncle, 201- shank body, 202- bearing, 203- endoporus, 300- extension,
400- guide hole, 10- optical fiber, 20- glue.
Specific embodiment
As shown in Fig. 2 the fiber-optical movable connector pin of the present invention, including lock pin body 100 and caudal peduncle 200.
There is centered on lock pin body 100 cylinder of micropore 101, caudal peduncle 200 includes shank body 201 and is located at shank body 202
The bearing 202 of front end.Bearing 202 interference fit is crimped on the rear end of lock pin body 100, and shank body 100 center has facial expression fibre 10
The endoporus 203 penetrating, this endoporus 203 penetrates into the micropore 101 of lock pin body 100 always.
In the present invention, lock pin body 100 has an extension 300 with respect to prior art, for example original contact pin
Length is 8mm, and the overall length after lock pin body 100 increases extension 300 is 12.6mm.In extension 300 original position (i.e. contact pin
The position of length 8) it is provided with two guide holes 400 being vertically passed through endoporus, this guide hole 400 is oppositely arranged on the upper of endoporus 203
Side and lower section., guide hole 400 is the horn mouth of big upper and lower small mouth taking the guide hole of top as a example.
It is exactly more than the fiber-optical movable connector pin of the present invention, when using, after insertion optical fiber, only to before guide hole
The glue for fixing optical fiber is injected, unnecessary glue can ooze out from guide hole and solidify in the shank body of side, and extension
Do not need between endoporus and optical fiber inject glue, optical fiber can fine motion in the endoporus of extension, so have the following advantages:
1st, unnecessary glue can be guided by contact pin by guide hole, help check glue quantity and solidification effect simultaneously
Whether fruit meets technological requirement；
2nd, the square optical fiber at guide hole rear is extended section when bending and stops, will not concentrate larger bending stress
Fibercuts can effectively be prevented in glue curing point.
Therefore, the fiber-optical movable connector pin of the present invention has the advantages that to prevent fibercuts.
