Abstract

The utility model discloses a quick optical fiber connector, comprising an optical fiber butting element for butting optical fibers and a housing, wherein the optical fiber butting element comprises a connection end; a through hole smaller than the connection end in caliber is formed on the housing; the optical fiber butting element is sleeved in the through hole; and an elastic element is sleeved to the connection end. Compared with the prior art, the quick optical fiber connector has the following advantage that the optical fiber butting element and the housing thereof are firmer in connection and not easy to become loose, so that the alignment accuracy of the optical fibers is guaranteed.

Description

Optical fiber quick connector

Technical field

The utility model relates to joints of optical fibre field, concrete relates to a kind of optical fiber quick connector.

Background technology

General and the supporting use of fiber-optical socket of optical fiber quick connector, thereby the quick grafting of realization optical fiber, quick coupler is realized the butt joint of optical fiber through compressing the termination of two optical fiber.Usually, have one to be to be embedded in the tail optical fiber in the lock pin when dispatching from the factory in two optical fiber, another is the actual fiber that is connected with tail optical fiber according to user's actual needs.Article two, optical fiber docks in the V-type groove, covers the gland on the V-type groove then, and optical fiber is squeezed in the V-type groove.

The core component structure of existing fiber quick coupler; Generally form by housing and fiber alignment assembly two parts; What design was adopted usually is that the riveting of fiber alignment assembly is gone in the housing inner chamber, is referred to as integrated, this docking mode; Fiber alignment spare is loosening in housing easily, thereby influences the butt joint accuracy of optical fiber in the optical fiber quick connector.

Summary of the invention

To the problem that exists in the prior art, the utility model provides a kind of fiber alignment spare and the fixing more firm optical fiber quick connector of housing.

In order to solve the problems of the technologies described above; The utility model is able to solve through following technical proposals: optical fiber quick connector; Comprise being used to make optical fiber to carry out fiber alignment spare and housing to part, described fiber alignment spare comprises a link, and described housing is provided with the through hole of bore less than the link bore; Said fiber alignment spare is sheathed in the said through hole, on said link, is arranged with elastic component.

In the technique scheme, preferred, described elastic component is a spring.

The utility model compared with prior art has following beneficial effect: the fiber alignment spare of optical fiber quick connector is connected more firm difficult loosening with housing, thereby has guaranteed the alignment precision of optical fiber.

Fig. 2 is the utility model embodiment cut-open view.

Fig. 3 is the synoptic diagram of the utility model housing.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail: referring to Fig. 1 to Fig. 3; Optical fiber quick connector; Comprise being used to make optical fiber to carry out fiber alignment spare 1 and housing 2 to part, referring to Fig. 1, described fiber alignment spare 1 comprises a link 11; Said link 11 tops are provided with a circle elastic bumps wall 111, and the tailstock of said link 11 is provided with crowning 112.

Referring to Fig. 2 to Fig. 3, described housing 2 is provided with the holding tank 21 of receiving optical fiber interfacing part 1, and housing is provided with the through hole 6 of bore less than concave wall 111; Described fiber alignment spare 1 is arranged in the holding tank 21, and is equipped with spring 3 on the link 5 of fiber alignment spare 1, and said link 5 passes described through hole 6; When fiber alignment spare 1 in housing 2 fixedly the time; Spring 3 just relies between crowning 112 and the enclosure interior, gives power left of crowning, gives power to the right of inner walls; Make that fiber alignment spare 1 is difficult in housing 2, sliding relatively, guaranteed the alignment precision of optical fiber.In the technique scheme, described spring 3 also can be other elastic component, so long as play the replacement of equivalent action, also should be in the protection domain of the utility model certainly.
