Abstract
The invention relates to the field of optical connectors, in particular to a bending type movable optical fiber connector. The bending type movable optical fiber connector comprises a shell body and an optical contact element which is arranged in the shell body. The rear end of the shell body is fixedly provided with a limiting seat and a rigid leading wire cover which is provided with a leading wire hole. The optical contact element is connected with an optical cable which penetrates through the leading wire hole and then leads out a wire. The leading wire cover is bent towards the direction of the leading-out wire of the optical cable, and the outlet of the leading wire hole is arranged towards the direction of the leading-out wire of the optical cable. Arc-shaped support surface is arranged on the hole wall of the leading wire hole. Under the supporting effect of the support surface, when the optical cable is subjected to tension along the direction of the leading-out wire, the bending radius is not smaller than the permitted bending radius. On one hand, the connector prevents the problem that the leading wire cover incises the optical cable from occurring, on the other hand, the connector fundamentally prevents the problem that the optical cable is bent and damaged from occurring. Therefore, the bending type movable optical fiber connector solves the problem that leading wire covers of existing bending type connectors are prone to damage of optical cables.
Description
Technical field
The present invention relates to the optical connector field, especially relate to a kind of curved formula free fiber-optics connector.
Background technology
Free fiber-optics connector is comparatively common a kind of in the optical connector; these type of joints of optical fibre in use; need easily in order to connect up; usually needing will be from the optical cable bending of its afterbody; yet optical fiber has strict requirement to radius bend; therefore present way is that afterbody at the optical connector housing is provided with corresponding protection annex; such as the curved formula LC joints of optical fibre comparatively common on the market; see Fig. 1-2; such joints of optical fibre are by fix assembling limit base 101 at its afterbody; the mode of lead-in wire cover 102 and curved formula sheath 103 is protected afterbody optical fiber 104; wherein; described limit base 101 is fixed together with joints of optical fibre housing and its rear end has sleeve part; lead-in wire cover 102 is inserted in the sleeve part of limit base and with limit base 101 and fixedly is crimped on; 103 of curved formula sheaths are enclosed within the afterbody of lead-in wire cover 102; said structure has been alleviated the optical fiber curved transitions and the problem damaged to a certain extent; but; because described lead-in wire cover all is metallic sheaths of straight barrel type; and curved formula sheath is generally soft rubber sleeve; optical cable jumper need to have certain stretching resistance at its outlet direction often; when optical cable when its wrap direction is subject to larger tensile force f; optical cable and curved formula sheath all bend from the afterbody of lead-in wire cover; at this moment; the end of lead-in wire cover forms the edge structure of cutting optical cable and curved formula sheath; this will directly cause the increase of optical cable loss, even the optical cable that fractures.
Summary of the invention
The object of the present invention is to provide a kind of curved formula free fiber-optics connector, the problem of overlapping fragile optical cable with the lead-in wire that solves existing curved formula optical connector.
In order to address the above problem, curved formula free fiber-optics connector of the present invention is by the following technical solutions: a kind of curved formula free fiber-optics connector, this connector is take front end as inserted terminal, comprise housing and be assemblied in light contact element in the housing, the rear end of described housing fixedly is equipped with the lead-in wire cover of limit base and rigidity, the leaded hole of lead-in wire tackling, the light contact element is connected with optical cable, optical cable passes outlet behind the described fairlead, described lead-in wire cover to the bending of the outlet direction of optical cable and so that the outlet of fairlead towards the outlet direction of optical cable, the supporting surface that has arc on the hole wall of fairlead, under the supporting role of this supporting surface, the crooked process radius the during pulling force of optical cable on being subject to outlet direction is not less than it and allows radius bend.
The hole wall of described fairlead upwards cooperates with optical cable is spacing in the footpath of optical cable.
The outer cover of lead-in wire cover is equipped with curved formula sheath.
Since the lead-in wire cover of curved formula free fiber-optics connector of the present invention to the outlet direction bending of optical cable and so that the outlet of fairlead towards the outlet direction of optical cable, the supporting surface that has simultaneously arc on the hole wall of fairlead, and under the supporting role of this supporting surface, crooked process radius during the pulling force of optical cable on being subject to outlet direction is not less than it and allows radius bend, therefore, in use, the Way out of bullport is identical with the outlet direction of optical cable, thereby the problem of having stopped lead-in wire cover cutting optical cable occurs, in addition, owing to adopt the hard mode that supports of cambered surface to limit the crooked process radius of optical cable, therefore also fundamentally stop optical cable and rolled over the generation of bad problem, this shows the problem that the lead-in wire that curved formula free fiber-optics connector of the present invention has solved existing curved formula optical connector overlaps fragile optical cable.
