[0033] like Figures 1 to 4 As shown, this embodiment provides a positioning fixture for assembling a fiber optic connector 100, which includes a ferrule assembly 110 and a shell 120. The ferrule assembly 110 includes a plug 111, a plug connector 112, an optical fiber 113, a tail connector 114 and a dust cap 115. The plug 111, the plug connector 112, the optical fiber 113 and the tail connector 114 are connected in sequence, and the dust cap 115 is sleeved on the plug 111. The shell 120 includes a first shell 121 and a second shell 122. The second shell 122 is provided with a second clamping structure. The first clamping structure can be clamped with the second clamping structure to each other, so that the first shell 121 and the second shell 122 are clamped with each other, and the optical fiber 113 can be installed between the first shell 121 and the second shell 122 that are clamped with each other. The positioning fixture is used to assemble the installed ferrule assembly 110 with the shell 120.

[0034] The positioning fixture includes a positioning member 1, and the positioning member 1 is provided with a first positioning groove 11, a second positioning groove 12, a third positioning groove 13 and a fourth positioning groove 14 that are connected in sequence. The first positioning groove 11 is used to engage with the dust cap 115, the second positioning groove 12 is used to engage with the plug connector 112, and the third positioning groove 13 is used to engage with the first shell 121, so that the plug connector 112 is staggered with the first engaging structure, and the fourth positioning groove 14 is used to engage with the tail connector 114. When assembling, first engage the first shell 121 to the third connector, then engage the dust cap 115 of the ferrule assembly 110 into the first positioning groove 11, and then engage the plug connector 11 2 is clamped into the second positioning groove 12, and the tail end connector is clamped into the fourth positioning groove 14. Finally, the optical fiber 113 is neatly combed in the first shell 121, and the second shell 122 is clamped with the first shell 121 to complete the assembly. The first shell 121 and the ferrule assembly 110 are fixed by the positioning fixture, so that the worker can conveniently and accurately fix the optical fiber 113 in the first shell 121, and can avoid the plug connector 112 from blocking the first clamping structure, so that the second clamping structure can be clamped with the first clamping structure, thereby facilitating the assembly of the first shell 121 and the second shell 122, which can improve assembly efficiency and reduce workload.

[0035] like Figure 2 As shown, in this embodiment, the first snap-fitting structure includes a first snap-fitting structure 1211 and a first snap-fitting groove 1212, and the second snap-fitting structure includes a second snap-fitting structure 1221 and a second snap-fitting groove 1222. The first snap-fitting structure 1211 can be snap-fitted with the second snap-fitting groove 1222, and the second snap-fitting structure 1221 can be snap-fitted with the first snap-fitting groove 1212. It is easy to understand that during the snap-fitting process, the first snap-fitting structure 1211 and the second snap-fitting structure 1221 will be slightly deformed, and deformation space needs to be reserved for them. Therefore, the plug connector 112 is snap-fitted and fixed in the second positioning groove 12 so that the plug connector 112 is staggered with the first snap-fitting structure 1211 and the first snap-fitting groove 1212, thereby avoiding the plug connector 112 from hindering the deformation of the first snap-fitting structure 1211 and the second snap-fitting structure 1221, and preventing the first snap-fitting structure 1211 and the second snap-fitting structure 1221 from being squeezed and broken.

[0036] Optionally, the first snap-fit ​​structure only includes the first snap-fit ​​1211, and the second snap-fit ​​structure only includes the second snap-fit ​​groove 1222, or the first snap-fit ​​structure only includes the first snap-fit ​​groove 1212, and the second snap-fit ​​structure only includes the second snap-fit ​​1221, which can also achieve the mutual snap-fitting of the first shell 121 and the second shell 122, and is not limited here.

[0037] Furthermore, since the optical fiber connector 100 includes at least two plugs 111, Figure 4 As shown, the positioning member 1 is provided with at least two first positioning grooves 11 in parallel, and second positioning grooves 12 corresponding to the first positioning grooves 11 one by one. Each first positioning groove 11 is connected to the third positioning groove 13 through the corresponding second positioning groove 12. The dust cap 115 sleeved on each plug 111 is clamped with the corresponding first positioning groove 11, and the plug connector 112 connected to the plug 111 is clamped in the corresponding second positioning groove 12. Each first positioning groove 11 is connected to the third positioning groove 13 through the corresponding second positioning groove 12, so that the optical fiber 113 connected to each plug connector 112 can be gathered into the first shell 121 clamped in the third positioning groove 13. A fixing structure for clamping and fixing the optical fiber 113 is provided in the first shell 121, and each plug connector 112 is clamped in the corresponding second positioning groove 12, so that each plug connector 112 is staggered with the first clamping structure. The first shell 121 and the second shell 122 are pressed and clamped to achieve assembly of the shell 120.

[0038] In order to facilitate the connection between the first shell 121 and the second shell 122, first positioning blocks 15 protruding from the surface of the positioning member 1 are provided on both sides of the third positioning groove 13. The first positioning blocks 15 are used to limit the second shell 122. The first positioning blocks 15 on both sides of the third positioning groove 13 jointly guide the second shell 122, so that the second shell 122 can be aligned with the first shell 121 for connection, thereby improving the installation efficiency of the shell 120.

[0039] Furthermore, at least two first positioning blocks 15 are spaced apart on both sides of the third positioning groove 13, so as to better limit the first shell 121, and workers can press and install the first shell 121 through the gap between two adjacent first positioning blocks 15 and observe whether it is snapped into place.

[0040] In this embodiment, a chamfer is provided on the top of one side of the first positioning block 15 close to the third positioning groove 13, which serves as a guide and positioning for the second shell 122 to enter the limiting space formed by the first positioning blocks 15 on both sides of the third positioning groove 13, thereby facilitating the second shell 122 to be snapped into the first shell 121.

[0041] Similarly, the first positioning slot 11 is chamfered at its opening to guide and position the dust cap 115 in engagement with the first positioning slot 11. The second positioning slot 12 is chamfered at its opening to guide and position the plug connector 112 in engagement with the second positioning slot 12. The third positioning slot 13 is chamfered at its opening to guide and position the first housing 121 in engagement with the third positioning slot 13. The fourth positioning slot 14 is chamfered at its opening to guide and position the tail connector 114 in engagement with the fourth positioning slot 14.

[0042] In addition, second positioning blocks 16 protruding from the surface of the positioning member 1 are provided on both sides of the second positioning groove 12 to better secure the plug connector 112. Similarly, the top of the second positioning block 16, which is close to the second positioning groove 12, is chamfered to guide and position the plug connector 112 when it is engaged with the second positioning groove 12.

[0043] Specifically, the above chamfers are all round chamfers, which can make the guidance smoother and further improve the assembly efficiency.

[0044] Furthermore, a fifth positioning groove 131 is defined at the bottom of the third positioning groove 13 . The fifth positioning groove 131 is used to engage with the protrusion 1213 on the first shell 121 , thereby better fixing the first shell 121 and preventing the first shell 121 from shaking during engagement.

[0045] In some embodiments, at least two fixing holes 17 are provided on the positioning member 1 for fixing the positioning member 1 on an external workbench. By passing fasteners through the fixing holes 17 and connecting to the workbench, the positioning fixture can be fixed on the workbench and the positioning fixture can be prevented from rotating, making it convenient for workers to assemble.

[0046] Furthermore, a tenon 18 is provided on one side of the positioning member 1 along the width direction, and a mortise 19 is provided on the other side. The tenon 18 can engage with the mortise 19 of the adjacent positioning member 1, thereby splicing multiple positioning jigs.

[0047] This embodiment also provides a fiber optic connector positioning assembly, including multiple positioning jigs as described above. Multiple positioning jigs can be spliced ​​in sequence along their width direction to assemble multiple fiber optic connectors 100. Workers can clamp multiple first shells 121 into corresponding second positioning grooves 12 at one time, and then clamp multiple core assemblies 110 with corresponding positioning members 1, and finally clamp each second shell 122 with the corresponding first shell 121 to achieve batch assembly and further improve assembly efficiency.

[0048] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
