Abstract
The utility model discloses a high-precision optical fiber insertion core adapter, which comprises a shell and a sleeve, wherein the sleeve is fixed in the shell; the outer wall of the middle section of the sleeve is provided with a groove; a reed is arranged between the sleeve and the inner wall of the shell in a compression joint way; the reed is arranged between the outer wall of the sleeve and the inner wall of the shell; and a middle projecting part of the reed is arranged in the groove. According to the adapter, a contact pin is in interference fit with an inner hole of the sleeve under the action of the reed when an optical fiber connector is inserted from the two ends of the adapter, and the sleeve is prevented from moving slightly, so that accurate alignment of contact pins inserted in two directions is realized; and the high-precision optical fiber insertion core adapter has a simple structure and high generality.
Description
Technical field
The utility model belongs to optical-fibre communications field, relates to a kind of high-precision optical fiber lock pin adapter.
Background technology
Fiber adapter is a fiber active linker centering link.Be to couple together through its inner split coupling between the optical fiber, to guarantee the highest switching performance between the optical patchcord by adapter.Conventional adapter all is to be installed in the housing by sleeve pipe to constitute, and has microgap between sleeve pipe and the housing, and when the two-way insertion of contact pin, sleeve pipe can be followed contact pin and done tiny moving, and influences bearing accuracy.
The utility model content
The utility model technical matters to be solved provides a kind of high-precision optical fiber lock pin adapter; Between sleeve and inner walls, be crimped with reed; Sidewall in the middle of the sleeve is provided with groove, and groove cooperates with convexity on the reed middle part, and is simple in structure; Can realize the accurate contraposition of two-way insertion contact pin, highly versatile.
The technical solution of utility model is following:
A kind of high-precision optical fiber lock pin adapter comprises housing and the sleeve that is fixed in the housing; The outer wall of said sleeve-interrupted is provided with groove, is crimped with reed between said sleeve and the inner walls, and reed is arranged between sleeve outer wall and the inner walls, and the intermediate projections portion of reed is arranged in this groove.
Described groove and reed are 2, the axis symmetry of the relative sleeve in position of 2 grooves.
Beneficial effect:
This practical high-precision optical fiber lock pin adapter is crimped with reed between sleeve and inner walls, the sidewall in the middle of the sleeve is provided with groove; Groove cooperates with convexity on the reed middle part; Simple in structure, can realize the accurate contraposition of two-way insertion contact pin, highly versatile.
Description of drawings
Fig. 1 is the utility model high-precision optical fiber lock pin adapter structure synoptic diagram.
1 is housing among the figure, and 2 is sleeve, and 3 is reed, and 4 are optical fiber contact pins insertion mouth.
Embodiment
Below will combine accompanying drawing and specific embodiment that the utility model is explained further details:
As shown in Figure 1, a kind of high-precision optical fiber lock pin adapter comprises housing and the sleeve that is fixed in the housing; The outer wall of said sleeve-interrupted is provided with groove, is crimped with reed between said sleeve and the inner walls, and reed is arranged between sleeve outer wall and the inner walls, and the intermediate projections portion of reed is arranged in this groove.Described groove and reed are 2, the axis symmetry of the relative sleeve in position of 2 grooves.The adapter of the utility model, under the effect of reed, when the joints of optical fibre inserted from adapter two, contact pin and sleeve endoporus formed interference fit, and sleeve does not have tiny moving, thereby realizes the accurate contraposition of two-way insertion contact pin, and is simple in structure, highly versatile.
