Abstract
The utility model relates to a pin component of an optical fiber connector. The pin component comprises a pin shell which consists of a front shell and a rear shell, wherein a ring groove into which a convex ring on the inner wall surface of a corresponding protection shell is embedded is coaxially formed on the outer wall surface of the rear shell; and the front and rear groove walls and/or groove bottom of the ring groove are/is provided with a fit surface which is in interference fit with the convex ring on the inner wall surface of the corresponding protection shell. The ring groove is formed on the rear shell of the pin component of the optical fiber connector, and the front and rear groove walls and/or groove bottom of the ring groove are/is provided with the fit surface which is in interference fit with the convex ring on the inner wall surface of the corresponding protection shell, so the pin component and an inner shell can be fixed by forcedly inserting the pin component into the corresponding protection shell during assembly of the optical fiber connector, the processes of adhesive-filling and pressing of the conventional optical fiber connector are eliminated, and the problem of low assembly efficiency during manufacturing of the optical fiber connector is solved.
Description
Technical field
The utility model relates to the optical cable connection device, especially a kind of ferrule of optical fiber connector assembly.
Background technology
Compare with connected modes such as welding, cold joint or the on-the-spot mill at traditional fiber terminal connect, interconnection technique adopts optical fiber direct-passing mode, i.e. optical fiber connectionless point in advance.According to requirement of client, by factory's tailor-make product, the attrition process of the column criterion of going forward side by side program, all technical indicators are observed IEC, TIA and relevant standard, and in this, technical indicator surmounts the connector that on-the-spot mill connects far away.Wherein the joints of optical fibre are exactly an indispensable critical component in the preparatory interconnection technique; The general optical fiber connector includes the contact pin assembly; Said contact pin assembly comprises the procapsid of rectangle and the back casing of rectangle, and forward and backward housing is pegged graft mutually and movablely vertically in the endoporus of the two is equipped with Plug pin patch bay, is fixed in the contact pin on the Plug pin patch bay and is mounted on the buffer spring between Plug pin patch bay rear end and the back casing; The above-mentioned joints of optical fibre have all obtained using widely in various fields; But but be not suitable for preparatory connection optical cable; Trace it to its cause; Then mainly be because not have the intensity of dustproof, waterproof construction and forward and backward housing limited the outside of the above-mentioned joints of optical fibre, can't satisfy the requirement of the joints of optical fibre of preparatory connection optical cable; In order to address this problem; Present way is the protection housing that is provided for protecting the contact pin assembly in the outside of said forward and backward housing in addition; And owing to all do not have corresponding syndeton on the said forward and backward housing, therefore during fabrication, often coaxial being assemblied in of described contact pin assembly protected in the housing; Compress through nut then or the mode of encapsulating fixing seal is fixedly connected back casing with the protection housing that other establishes; This then greatly reduces the efficiency of assembling to the joints of optical fibre that are applicable to preparatory interconnection technique, and when especially adopting the fixing mode of encapsulating, its technological process especially and complicated.In sum, the existing equal manufacturing process complicacy of the joints of optical fibre that is applicable to preparatory interconnection technique can't satisfy development in enormous quantities, high speed, disagrees with the present market demand.
Summary of the invention
The purpose of the utility model is to provide a kind of ferrule of optical fiber connector assembly, to solve the low problem of joints of optical fibre efficiency of assembling during fabrication.
In order to address the above problem; The ferrule of optical fiber connector assembly of the utility model adopts following technical scheme: the ferrule of optical fiber connector assembly; Comprise by forward and backward housing plugging together the contact pin housing that forms the coaxial annular groove that supplies the bulge loop on the corresponding protection housing internal face to embed that is provided with on the outside wall surface of said back casing; Front and back two cell walls of said annular groove and/or its bottom land have be used for and corresponding protection housing internal face on the mating surface of bulge loop interference fit.
The outside wall surface of said back casing is provided with and is used for only revolving ending spin slot or only revolving key of cooperation with corresponding protection housing.
Described annular groove is by surround with the forward and backward bulge loop on the outside wall surface that is located in said back casing successively backward vertically in the past.
The said spin slot that ends is opened on the described preceding bulge loop.
The front end of said back casing is provided with the radially elasticity voussoir of harmomegathus; Said procapsid is provided with and said elasticity voussoir fore shell hanging hole one to one, the front end of back casing insert behind the procapsid through its elasticity voussoir be flush-mounted in the corresponding fore shell hanging hole and with the procapsid secure fit.
Because said ferrule of optical fiber connector assembly is provided with said annular groove on its back casing, front and back two cell walls of said annular groove and/or its bottom land have and are used for and the corresponding mating surface of protecting the bulge loop interference fit on the housing internal face; Therefore when assembling, only need said contact pin assembly packed into by force corresponding protection housing and and be located at bulge loop interference fit on the protection housing internal face and can realize fixing between contact pin assembly and the inner housing; Omitted traditional joints of optical fibre encapsulating, processing step such as press-fit, thereby solved the low problem of joints of optical fibre efficiency of assembling during fabrication.
