Description

Technical Field

[0001] This utility model relates to the field of optical fiber adapter manufacturing tools, and in particular to an assembly fixture for optical fiber adapters. Background Technology

[0002] Fiber optic adapters, also known as flanges or fiber optic connectors, are key components used for aligning and connecting fiber optic cables. In fiber optic communication systems, fiber optic adapters are among the most commonly used passive optical devices. They mainly consist of three parts: two fiber optic connectors and a coupler. The two fiber optic connectors are installed at the ends of the two optical fibers, while the coupler aligns the connectors to ensure precise splicing between the fibers.

[0003] During fiber optic adapter assembly, alignment sleeves need to be inserted from both ends of the adapter housing, ensuring they are aligned on the same straight line so that the end faces of the two optical fibers are aligned. Accurate alignment of the alignment sleeves often relies on the precision of the adapter housing's internal dimensions. However, the adapter housing's internal cavity typically has a clearance fit with the alignment sleeves, which presents two challenges: firstly, alignment is difficult during insertion; secondly, adhesive is needed for bonding and filling after insertion. During adhesive curing, without external force to maintain the alignment sleeves' position, misalignment can easily occur at both ends. Therefore, there is an urgent need for an assembly fixture that can guarantee precise assembly of fiber optic adapters. Utility Model Content

[0004] The purpose of this invention is to provide an assembly fixture for an optical fiber adapter to solve the problem of difficulty in aligning the alignment sleeve when it is installed into the adapter housing, and the problem that the two ends of the alignment sleeve are very prone to misalignment after installation.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An assembly fixture for an optical fiber adapter is disclosed, which inserts an alignment sleeve into an adapter housing. The assembly fixture includes a chassis, a mounting base, and a clamping and calibration mechanism. The mounting base and the clamping and calibration mechanism are symmetrically mounted on the chassis. The two mounting bases are adapted to the two sides of the adapter housing, and the working ends of the two clamping and calibration mechanisms are adapted to the alignment sleeve and are on the same straight line.

[0007] A further technical solution is as follows: the clamping calibration mechanism includes a cylinder, a slide plate, a telescopic rod, and a ejector pin. The cylinder is vertically mounted on the side of the chassis. The slide plate is vertically arranged and slidably mounted on the chassis. The power output end of the cylinder is connected to the slide plate. The telescopic rod is symmetrically arranged and vertically mounted on the side of the slide plate. The ejector pin is concentrically mounted on the end of the telescopic rod. The ejector pin is adapted to the alignment sleeve.

[0008] A further technical solution is that the telescopic rod is a spring strut.

[0009] A further technical solution is that the end of the ejector pin is provided with a stepped cone, and the diameter of the tail step of the stepped cone is larger than the diameter of the alignment sleeve.

[0010] A further technical solution is that a guide post is provided on the chassis, and the guide post is slidably connected to the sliding plate.

[0011] A further technical solution is that the card holder has a U-shaped structure.

[0012] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0013] This invention proposes an assembly fixture for fiber optic adapters. The fixture is easy to operate and allows the adapter housing to be quickly installed on the fixture's mounting base for positioning. Furthermore, a clamping and calibration mechanism is used to fix and tighten the alignment sleeve, ensuring accurate alignment of the alignment sleeve during the adhesive curing process. This significantly improves the assembly efficiency and product quality of the fiber optic adapter. Attached Figure Description
