Description

Technical Field

[0001] This utility model relates to the field of optical communication device manufacturing technology, and in particular to a modular, replaceable clamping structure MT-FA fiber array length fixture. Background Technology

[0002] MT-FA fiber array fixtures are an important tool in the manufacture of optical communication devices, used for precise positioning, fixing, testing and processing of fiber arrays.

[0003] Traditional MT-FA fixtures, such as Figure 1 , Figure 2 The diagram shows a base 1, a clamping component 2, and a base plate 3. In practical applications, the following pain points exist: 1. Traditional fixtures adopt an integral structure, with the clamping components and the base being machined as a single unit, which is a non-modular design. When the product shape changes (such as differences in the shell structure of MT-FA from different manufacturers), the entire fixture needs to be redesigned and manufactured, resulting in a long development cycle and high costs.

[0004] 2. The clamping parts usually require complex slot and hole machining (such as irregular slots and multi-point positioning mechanisms), which rely on high-precision CNC technology, resulting in low material utilization and a single fixture cost of up to thousands of yuan, leading to high processing costs.

[0005] 3. The production line needs to reserve dozens or even hundreds of jigs for different models of products, which ties up capital and warehousing resources, resulting in high inventory pressure. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a modular and replaceable clamping structure MT-FA fiber array fixed length fixture to solve the problems existing in the background art.

[0007] This utility model provides the following technical solution: a modular, replaceable clamping structure MT-FA fiber array length fixture, comprising: The base module has a first slot at one end for attaching the MT. The clamping module is slidably fastened to the other end of the base module, and a second slot for engaging the FA is provided on the surface of the clamping module. Screws are threadedly connected to the base module and clamping module.

[0008] Preferably, the other end of the base module is provided with a sliding groove, the width of which is adapted to the clamping module, and the tail of the sliding groove is also provided with a notch.

[0009] Preferably, the clamping module has a stop at its tail end, and the stop is positioned inside the notch.

One side of the positioning block is rotatably connected to the adjusting rod, and the positioning block is placed in the positioning groove.

[0013] Preferably, a connecting groove is provided at one end corner of the positioning groove near the second slot.

[0014] Preferably, the positioning block has an L-shaped structure, with its two ends placed in the positioning groove and the connecting groove, respectively.

[0015] Preferably, the base module is made of hard anodized aluminum alloy.

[0016] Preferably, the clamping module and the positioning block are made of PEEK material.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model consists of a separate base module and a clamping module. By adding screws for assembly, the clamping module and the base are assembled separately, realizing "one base to adapt to N kinds of MT-FA products", which greatly reduces the development cycle and investment costs, and effectively alleviates the pressure of inventory.

[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0027] This invention provides a modular, replaceable clamping structure for MT-FA fiber array length fixing, such as... Figure 3-6 As shown, it includes: base module 1, clamping module 2, and screw 3.

[0028] Specifically, one end of the base module 1 has a first slot 11 for engaging the MT. The surface of the clamping module 2 has a second slot for engaging the FA. The clamping module 2 is slidably fastened to the other end of the base module 1 and fixed by screws 3, so that the base module 1 and the clamping module 2 can be directly and detachably connected.

[0029] This application proposes a fixture consisting of a separate base module 1 and a clamping module 2, which are assembled using additional screws 3. The clamping module and the base are assembled separately, enabling "one base to adapt to N types of MT-FA products", thereby greatly reducing the development cycle and investment costs, and effectively alleviating inventory pressure.

[0030] Meanwhile, the base module 1 and clamping module 2 are detachable, so when either the base module 1 or the clamping module 2 is damaged, only the local parts need to be replaced, reducing maintenance costs.

[0031] Furthermore, a sliding groove 12 is provided at the other end of the base module 1. The width of the sliding groove 12 is adapted to the clamping module 2, and a notch 3 is provided at the tail of the sliding groove 12. A stop block 22 is provided at the tail of the clamping module 2, and the stop block 22 is placed inside the notch 13.

[0032] During assembly, the clamping module 2 is placed inside the slide groove 12 opened in the base module 1 until it is blocked by the end block 22 inside the notch 13. At this time, the base module 1 and the clamping module 2 fit together, and then the screws 3 are installed to fix it.

[0033] Furthermore, the screw 3 passes laterally through the stop block 22 and is threaded to the tail end face of the base module 1. That is, a hole for the screw 3 to pass through is provided on the side of the stop block 22, and a threaded hole adapted to the screw 3 is provided on the tail end face of the base module 1, which corresponds to the hole.

[0034] Furthermore, the clamping module 2 is provided with a vertically penetrating positioning groove 23 on one side of the second slot 21, and one side of the positioning groove 23 is connected to the second slot 21.

[0035] Furthermore, it also includes an adjusting rod 4 and a positioning block 5. The adjusting rod 4 is threaded to the side of the clamping module 2, and one end of it extends into the positioning groove 23. One side of the positioning block 5 is rotatably connected to the adjusting rod 4, and the positioning block 5 is placed in the positioning groove 23. Twisting the adjusting rod 4 moves the positioning block 5 inside the positioning groove 23, thereby abutting against FA inside the second slot 21, so that FA is firmly fixed in the second slot 21.

[0036] When the positioning block 5 is damaged, the adjusting rod 4 can be removed and the positioning block 5 can be directly pulled out for replacement without disassembling the base module 1 or the clamping module 2, making it convenient to use.

[0037] Furthermore, a connecting groove 231 is provided at one end of the positioning groove 23 near the second slot 21. The positioning block 5 has an L-shaped structure. The two ends of the positioning block 5 are respectively placed in the positioning groove 23 and the connecting groove 231. The positioning groove 23 is used to limit one end of the positioning block 5 so that the positioning block 5 can move horizontally, while the other end of the positioning block 5 is placed inside the connecting groove 231 to abut and fix FA.

[0038] Furthermore, the base module is made of hard anodized aluminum alloy, which not only increases the service life but also improves the heat conduction efficiency of the fixture.

[0039] Furthermore, the clamping module and positioning block are made of PEEK material to facilitate processing.

[0040] Several points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
