[0002] At present, a fiber optic connector is a device for detachably connecting between optical fibers. It precisely docks the two end faces of the optical fibers so that the optical energy output from the transmitting optical fiber can be coupled into the receiving optical fiber to the maximum extent, and the influence on the system caused by its intervention in the optical link is minimized. This is the basic requirement of the fiber optic connector. To a certain extent, the fiber optic connector affects the reliability and various performances of the optical transmission system. The key component of the fiber optic connector is the ceramic ferrule, and the high-precision alignment of the optical fiber is achieved by the ceramic ferrule. To achieve precise alignment, it is necessary to grind the protruding end face of the ceramic ferrule.

[0025] Combined with Figures 1-3 As shown, the embodiment of the present disclosure provides a grinding fixture for a semi-finished LCUPC type fiber optic connector. The semi-finished LCUPC type fiber optic connector includes a ferrule. The grinding fixture includes a main body 1 and a cover body 2. The main body 1 is provided with an installation groove 11. The installation groove 11 extends along the width direction of the main body 1 and penetrates the main body 1, and is suitable for the ferrule to be inserted into the installation groove 11 along the extension direction of the installation groove 11. The cover body 2 is covered on the main body 1 to cover the installation groove 11 and fix the ferrule.

[0026] Adopt a grinding fixture for semi-finished LCUPC fiber optic connectors provided by the embodiments of the present disclosure. Insert the ferrule to be ground into the installation groove 11 of the grinding fixture, cover the cover body 2 on the main body 1, and the cover body 2 and the main body 1 jointly position the ferrule to fix the ferrule to the grinding fixture, facilitating subsequent grinding of the ferrule. Compared with the related art, in this application, the ferrule is pre-ground separately in advance, and the deviation angle of the end face of the ground ferrule is measured. When assembling the loose parts, the deviation angles are uniformly positioned, improving the consistency of the connectors and reducing the docking loss difference between different connectors.

[0027] Based on the above technical solution, the number of the installation grooves 11 is multiple, and the multiple installation grooves 11 are arranged at intervals in sequence along the length direction of the main body 1.

[0028] Specifically, the number of the installation grooves 11 can be one or multiple. In this application, the case where the number of the installation grooves 11 is multiple is taken as an example. When the number of the installation grooves 11 is multiple, multiple ferrules can be installed into the corresponding installation grooves 11 at the same time, and multiple ferrules can be ground simultaneously, shortening the total grinding time and improving the grinding efficiency. The multiple installation grooves 11 are arranged at intervals in sequence along the length direction of the main body 1, so that interference during the grinding process of two adjacent ferrules can be avoided, preventing the influence on the grinding quality.

[0029] Based on the above technical solution, the main body 1 is further provided with an installation hole 12, the installation hole 12 extends along the height direction of the main body 1, and the grinding fixture further includes a fixing member, and the fixing member is arranged in the installation hole 12 and used for adsorbing and fixing the cover body 2.

[0030] The fixing member can be a magnet, and the cover body 2 is a magnetic substance that can be attracted by the magnet. When the cover body is covered on the main body 1, the fixing member generates an adsorption force on the cover body 2, thereby fixing the cover body on the main body 1. The side wall of the cover body facing the main body 1 and the installation groove 11 of the main body 1 jointly fix and position the ferrule. In addition, the ferrule includes a metal tail stock. The setting of the fixing member also generates a certain adsorption force on the ferrule, which can further fix the ferrule. The cover body 2 and the main body 1 are fixed by the adsorption force of the fixing member, facilitating the installation and disassembly of the cover body 2, and there is no need to set a fixing structure on the cover body 2, reducing the process complexity and saving a certain manufacturing cost.

[0031] Based on the above technical solution, the number of the installation holes 12 is multiple, and the multiple installation holes 12 are arranged at intervals in sequence along the length direction of the main body 1.

[0032] A plurality of mounting holes 12 are correspondingly provided with a plurality of fixing members. The plurality of fixing members are arranged at intervals in sequence along the length direction of the main body 1 and are evenly distributed on the main body 1. When the cover body 2 is covered on the main body 1, the adsorption force received by the cover body 2 is evenly distributed. In this way, the cover body 2 and the main body 1 are fixed more stably, so that the ferrule in the mounting groove 11 can be fixed better.

[0033] Based on the above technical solution, the plurality of mounting grooves 11 and the plurality of mounting holes 12 are arranged crosswise in sequence along the length direction of the main body 1.

[0034] Specifically, one mounting hole 12 is arranged at the position between two adjacent mounting grooves 11. The fixing member arranged in the mounting hole 12 adsorbs the cover body 2 to further fix the ferrules in the two adjacent mounting grooves 11. By analogy, the plurality of mounting grooves 11 and the plurality of mounting holes 12 are arranged crosswise in sequence along the length direction of the main body 1. That is to say, one mounting hole 12 is arranged between every two adjacent mounting grooves 11, and one mounting groove 11 is arranged between every two adjacent mounting holes 12. The fixing members of the mounting holes 12 on both sides of each mounting groove 11 fix the cover body 2 to fix the ferrule installed in the middle mounting groove 11.

[0035] Based on the above technical solution, the length and width of the cover body 2 respectively match the length and width of the main body 1.

[0036] Combined Figure 4 As shown, an embodiment of the present disclosure provides a grinding device, which includes a base 3 and a grinding fixture for a semi-finished LCUPC type optical fiber connector as described in any one of the above embodiments. The base 3 is provided with a fixture setting groove 31, and the fixture setting groove 31 is provided with a grinding hole 32. The grinding fixture is arranged in the fixture setting groove 31 so that the ferrule is inserted into the grinding hole 32.

[0037] The grinding device provided by the embodiment of the present disclosure includes the grinding fixture as described in any one of the above disclosed embodiments, so it has all the beneficial effects of the grinding fixture as described in any one of the above disclosed embodiments, which will not be elaborated here.

[0038] Specifically, the number of the fixture setting grooves 31 can be one or multiple. When the number of the fixture setting grooves 31 is multiple, there are multiple corresponding grinding fixtures that can be placed. In this way, the number of ferrules that can be ground simultaneously can be increased, and the working efficiency can be improved.

[0039] The present invention has been described by way of example above, but the present invention is not limited to the above specific embodiments. Any modification or variation based on the present invention belongs to the scope protected by the present invention.
