Detailed implementation manners

[0020] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the implementation manners does not limit the present utility model.

[0021] As Figure 1 and Figure 2 shown, a carrier tray structure for carrying a fiber optic module FA provided by the present utility model includes a carrier board 1. The top surface of the carrier board 1 is recessed with an optical fiber positioning guide groove 3 and an avoidance space. The bottom wall of the avoidance space is provided with a connector clamping structure 5. The connector clamping structure 5 is provided with a plurality of connector clamping grooves 6. Both the connector clamping structure 5 and the avoidance space extend along the length direction of the carrier board 1. The connector clamping structure 5 divides the avoidance space into an inner avoidance groove 7 and an outer avoidance groove 8. The number of the optical fiber positioning guide grooves 3 is multiple, and the multiple optical fiber positioning guide grooves 3 are equidistantly arranged along the length direction of the carrier board 1. The optical fiber positioning guide groove 3 includes a main channel 9 and a plurality of branch channels 10. One end of the main channel 9 is respectively communicated with one end of the plurality of branch channels 10, and the other ends of the plurality of branch channels 10 are communicated with the inner avoidance groove 7. One branch channel 10 is correspondingly arranged with one connector clamping groove 6. Specifically, the fiber optic module FA includes a substrate 14, a plurality of optical fibers 15 and a plurality of connectors 16. Each connector 16 is connected to the substrate 14 via an optical fiber 15; FA is Fiber Array (optical fiber 15 array).

[0022] In practical applications, the substrate 14 of the optical module FA is placed in the main channel 9. Multiple optical fibers 15 of the optical module FA are not only accommodated in the main channel 9, but also dispersedly arranged in the corresponding branch channels 10. One branch channel 10 accommodates one optical fiber 15. Each connector 16 of the optical module FA is snap-fitted on a connector slot 6. One end of the connector 16 extends into the inner avoidance groove 7, and the other end of the connector 16 extends into the outer avoidance groove 8 to achieve the loading and positioning of the optical module FA. The connector snap-fitting structure 5 can not only snap-fit the connector 16, but also allow an external pressing claw to press the connector 16 onto the connector snap-fitting structure 5, so that an external structure can insert a device onto the connector 16 of the optical module FA. The structure of the present utility model is simple, and can achieve the positioning and loading of multiple optical modules FA at one time, improving the stability and position accuracy of transporting the optical module FA, and is particularly suitable for equipment for automatically feeding the optical module FA.

[0023] In this embodiment, a plurality of positioning holes are recessed on the bottom surface of the carrier plate 1. The positioning holes are used for the concave-convex fit with the positioning posts of the external structure to achieve the positioning of the carrier plate 1.

[0024] In this embodiment, the connector snap-fitting structure 5 includes two clamping plates 11 protruding from the bottom wall of the avoidance space. The two clamping plates 11 are arranged in parallel, and a clamping groove 12 is formed between the two clamping plates 11. The top surface of each clamping plate 11 is recessed with a plurality of grooves 13. Each connector slot 6 is composed of the clamping groove 12 and the corresponding groove 13. When the connector 16 is snap-fitted on the connector slot 6, the connector 16 is located on the grooves 13 corresponding to the two clamping plates 11, and the circular ring of the connector 16 is inserted into the clamping groove 12.

[0025] In this embodiment, the end of the branch channel 10 far from the main channel 9 is in a horn shape to form a flared structure, which is not easy to cause damage to the optical fiber 15.

[0026] In this embodiment, the carrier plate 1 is provided with a plurality of clamping mechanisms 17. The plurality of clamping mechanisms 17 are respectively arranged corresponding to the plurality of optical fiber positioning guide grooves 3. The clamping mechanism 17 is located at the end of the main channel 9 far from the branch channel 10. The clamping mechanism 17 is used to clamp the substrate 14 of the optical module FA in the main channel 9. In practical applications, after the substrate 14 of the optical module FA is accommodated in the main channel 9, the clamping mechanism 17 clamps the substrate 14 in the main channel 9 to ensure the position accuracy and stability of the substrate 14 in the main channel 9, thereby ensuring the stability and accuracy of positioning the optical module FA. Specifically, one clamping mechanism 17 clamps the substrate 14 in one optical fiber positioning guide groove 3.

[0027] In this embodiment, the clamping mechanism 17 includes a rotating clamping member 18 and an elastic member 19. The middle part of the rotating clamping member 18 is rotatably connected to the carrier plate 1. The pressing end of the rotating clamping member 18 is elastically connected to the carrier plate 1 via the elastic member 19. The clamping end of the rotating clamping member 18 can clamp the substrate 14 of the optical module FA in the main channel 9. Specifically, the elastic member 19 is a spring. In practical applications, under the elastic force of the elastic member 19, the clamping end of the rotating clamping member 18 clamps the substrate 14 in the main channel 9. When it is necessary to release (loosen) the substrate 14, a pressing force is applied to the pressing end of the rotating clamping member 18. The pressing end of the rotating clamping member 18 compresses the elastic member 19, causing the rotating clamping member 18 to rotate until the clamping end of the rotating clamping member 18 releases the substrate 14, and then the external manipulator can take away the optical module FA.

[0028] In this embodiment, the carrier plate 1 is provided with a through hole 20 and a rotating cavity 21 recessed from the side wall of the through hole 20. The rotating cavity 21 communicates with the main channel 9. The middle part of the rotating clamping member 18 is rotatably connected to the inner side wall of the rotating cavity 21. The clamping end of the rotating clamping member 18 can extend into the main channel 9 through the rotating cavity 21, and the pressing end of the rotating clamping member 18 is located in the through hole 20. The through hole 20 not only provides space for the pressing end of the rotating clamping member 18, but also provides an operating space for applying force to the pressing end of the rotating clamping member 18. Moreover, the design of the through hole 20 and the rotating cavity 21 makes the structure of the rotating clamping member 18 and the carrier plate 1 compact.

[0029] In this embodiment, a mounting hole 22 communicating with the through hole 20 is recessed on the bottom surface of the carrier plate 1. A mounting block 23 is embedded in the mounting hole 22. The mounting block 23 is provided with an extension plate. The two ends of the elastic member 19 respectively abut against the pressing end of the rotating clamping member 18 and the extension plate. The setting of the mounting block 23 not only facilitates the disassembly and assembly of the elastic member 19 and the rotating clamping member 18, but also reduces the wear of the carrier plate 1. The mounting block 23 is convenient for disassembly and assembly and has a low maintenance cost.

[0030] In this embodiment, fixing holes are recessed in both the pressing end of the rotating clamping member 18 and the extension plate. The end of the elastic member 19 is received in the corresponding fixing hole. This structural design plays a role in positioning the elastic member 19, making the working stability of the elastic member 19 good.

[0031] In this embodiment, a stacking support edge 24 is provided at the bottom edge of the carrier plate 1, and a stacking placement groove 25 is provided at the top edge of the carrier plate 1. In two stacked carrier plates 1, the stacking support edge 24 of the upper carrier plate 1 is placed in the stacking placement groove 25 of the lower carrier plate 1. This structural design enables multiple carrier plates to be stacked together, facilitating transportation, storage, and the like.

[0032] All the technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are preferred implementation solutions of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious substitution without departing from the concept of the technical solution is within the protection scope of the present utility model.
