Description

Optical fiber array

Technical Field

The utility model relates to the technical field of optical fibers, in particular to an optical fiber array.

Background

The optical fiber array can accurately position the optical fiber, so that the optical fiber array becomes an important coupling component for connecting an optical device and the optical fiber, and is widely applied to the manufacturing of optical communication devices, such as planar optical waveguides, arrayed waveguide gratings, micro-electro-mechanical systems, multi-channel optical modules and the like.

The existing optical fiber array consists of a step-shaped bottom plate with a V-shaped groove at the front end, a cover plate and optical fibers. China discloses a patent: an optical fiber array, patent No.: 2016207337665, this patent comprises apron, bottom plate and optic fibre, compares in common fiber array, has set up the V groove on the apron, can guarantee that the optic fibre laminates in the V groove. However, as with a common optical fiber array, the shapes of the bottom plate and the cover plate cause that optical fibers are not manufactured in a limited manner in the horizontal direction, lateral force is easily transmitted to the area, stress concentration is easily generated at the boundary of the V-groove, and meanwhile, because the boundary of the V-groove is the boundary of a bare part and a coating layer part of the optical fiber, glue and the optical fiber have difference in shrinkage rate, and when the temperature changes, the optical fiber is stressed, and finally the optical fiber at the position is failed.

Disclosure of Invention

The utility model mainly solves the technical problem of providing an optical fiber array, which is more convenient to process, better protects optical fibers and is more convenient to glue in actual production.

In order to solve the technical problems, the utility model adopts a technical scheme that: the utility model provides an optical fiber array, includes bottom plate and apron, apron and bottom plate cooperation, optic fibre sets up between apron and bottom plate, bottom plate up end parallel arrangement has a plurality of optic fibre standing grooves, the optic fibre standing groove is including the first groove and the second groove that set gradually and communicate, the up end of bottom plate front end is equipped with the boss, the bottom plate front end face be equipped with the communicating logical groove of second groove, the second groove is the chute that sets up downwards towards the logical groove direction slope of bottom plate.

Further, the inclined groove surface of the second groove is inclined downward from the junction of the second groove and the first groove.

Furthermore, the lower end face of the front end of the bottom plate is provided with a concave step vertical to the direction of the optical fiber.

Further, the fiber cladding of the optical fiber is arranged in the second groove of the bottom plate, and the boundary point of the fiber cladding and the coating layer is arranged on the downward-inclined groove surface of the second groove.

Furthermore, an upper transition inclined plane is arranged on the upper end faces of the boss and the bottom plate, and a lower transition inclined plane matched with the upper transition inclined plane is arranged on the cover plate.

The optical fiber array has the beneficial effects that:

1. the second groove is set as a chute, so that the optical fiber is effectively protected;

2. the arrangement of the lug boss ensures that the optical fiber is better protected;

3. the through groove, the first groove and the second groove are arranged, so that the bottom plate is more convenient to process;

4. the arrangement of the lug boss is increased, and the dispensing is more convenient in actual production.
