Abstract
The utility model discloses an optical fiber interface assembly, composed of a metal pedestal, a metal front cover, a ceramic ferrule and a ceramic sleeve. The outer wall of the ceramic sleeve is step-shaped, has a front end and a back end, the end close to a light source is the back end, and the other end is the front end, and the outer diameter of the back end is greater than that of the front end. Because the tube wall of the back end of the step-shaped ceramic sleeve is thicker, a holding force is enhanced by utilizing the thickness difference between the front end and the back end, and the product WIGGLE performance is improved by utilizing the holding force difference between the larger outer diameter part at the back end and the front end.
Description
Technical field
The utility model relates to joints of optical fibre technical field, relates in particular to a kind of optical fiber interface assembly.
Background technology
Optical fiber component generally combines by 4 or 5, and is as shown in Figure 1, mainly is made up of metab 2, metal bezel 3, ceramic insertion core 4, porcelain bushing 5.The optical fiber interface assembly is mainly realized the connection effect in the light communication process, and the one of which end converges the light source 1 said light that sends, and the other end is connected with optical patchcord 6 goes out light transmission, thereby realizes the propagation of light, and its mechanism of action is as shown in Figure 1.The meaning of WIGGLE test is exactly to wave test, or cries the non-axial force test.In the actual production life; The optical fiber interface assembly is a critical piece of guaranteeing that optical fiber connects; All can influence the transmitting effect of light for any influence in the reality or to the factor of the optical patchcord application of force, so the WIGGLE index also just becomes the performance index of the crucial examination of assembly.But present technology is difficult to reach requirement from structure to this index, the structure of porcelain bushing 5 as shown in Figures 2 and 3, porcelain bushing 5 is an opening; When in the front end coupling part during application of force, because casing wall is thin, grip force is not enough; The fiber alignment center of two ceramic insertion cores misplaces easily and produces a low-angle; Cause the butt joint dislocation, as shown in Figure 4, thus cause that optical power change is big.
Therefore, prior art awaits to improve and development.
The utility model content
In view of the deficiency of above-mentioned prior art, the purpose of the utility model is to provide a kind of optical fiber interface assembly, and there is the problem of defective in the WIGGLE aspect of performance that is intended to solve the optical fiber interface assembly.
The technical scheme of the utility model is following:
A kind of optical fiber interface assembly is made up of metab, metal bezel, ceramic insertion core and porcelain bushing, wherein; The outer wall of said porcelain bushing is a step shape, is divided into front-end and back-end, is the rear end near an end of light source; The other end is a front end, and the external diameter of rear end is greater than the external diameter of front end.
Described optical fiber interface assembly, wherein, the external diameter of the rear end of said porcelain bushing is than the big 0.2 ~ 0.3mm of front end.
Described optical fiber interface assembly wherein, is interference fit between the rear end of said metal bezel and porcelain bushing.
Beneficial effect: the optical fiber interface assembly of the utility model improves device WIGGLE performance index, has replaced traditional adhering process, and operation is simple to operation, also reduces the broken probability of happening of use middle sleeve.

Embodiment
The utility model provides a kind of optical fiber interface assembly, for purpose, technical scheme and the effect that makes the utility model is clearer, clear and definite, below to the utility model further explain.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The optical fiber interface assembly that the utility model provided, as shown in Figure 5, mainly form by metab 12, metal bezel 13, ceramic insertion core 14, porcelain bushing 15; It mainly improves and is, the outer wall of porcelain bushing 15 is processed into step shape, and is as shown in Figure 6; The porcelain bushing 15 of step shape is divided into front-end and back-end end two parts; End near light source is the rear end, and the other end is a front end, and the length of front end equals the length of rear end or is a bit larger tham about 0.1mm; The external diameter of rear end is than the big 0.2 ~ 0.3mm of external diameter of front end, and the external diameter of front end is identical with the external diameter of ordinary casing in the industry.It between the rear end of metal bezel 13 and porcelain bushing 15 interference fit.
Because the tube wall of the rear end of the porcelain bushing 15 of step shape is thicker, utilize the deviation of its front and back thickness to strengthen grip force, utilize its rear end large outer-diametric portion and front end grip force difference to improve product WIGGLE performance.Therefore when inserting the ceramic insertion core 14 of tie jumper in the endoporus of porcelain bushing 15; Its grip force is much more superior than existing porcelain bushing; Thereby the situation that the butt joint that when wire jumper bears external force, is produced is misplaced has obvious resistant function; Guarantee the accuracy of butt joint preferably, thereby improved the anti-WIGGLE performance of optical fiber interface assembly.
Should be understood that; The application of the utility model is not limited to above-mentioned giving an example; Concerning those of ordinary skills, can improve or conversion according to above-mentioned explanation, all these improvement and conversion all should belong to the protection domain of the utility model accompanying claims.
Claims (3)
1. an optical fiber interface assembly is made up of metab, metal bezel, ceramic insertion core and porcelain bushing, it is characterized in that; The outer wall of said porcelain bushing is a step shape, is divided into front-end and back-end, is the rear end near an end of light source; The other end is a front end, and the external diameter of rear end is greater than the external diameter of front end.
2. optical fiber interface assembly according to claim 1 is characterized in that, the external diameter of the rear end of said porcelain bushing is than the big 0.2 ~ 0.3mm of front end.
