[0002] With the advancement of communication technology, more and more data is being transmitted over the internet, and big data is having an increasingly significant impact on social development. Currently, mainstream communication products on the market draw on the technology of mature optical communication modules. However, existing optical module components lack proper contact at the optical ports, resulting in tiny gaps after assembly. During normal use, electromagnetic waves generated within the optical module can radiate through these gaps and interfere with other equipment.

However, the production and assembly of this product is not only difficult to operate, costly, and has poor product consistency, but also cannot achieve good electromagnetic shielding effect. For this reason, this solution proposes a pluggable optical module. Summary of the Invention

The bottom surface of the mounting groove is provided with a connecting groove and a movable groove arranged along its length direction. A threaded column is installed in the movable groove, and one end of the threaded column extends into the connecting groove. The outside of the threaded column is screwed with a movable block, and the top of the movable block is fixed to the bottom surface of the base plate. The outside of the threaded column is sleeved with a linkage gear, and the linkage gear is located in the connecting groove. The bottom surface of the clamping sleeve is fixed with a rack for driving the linkage gear to rotate while pressing the optical device.

[0011] As a further improvement of the above scheme, the top surface of the base plate is provided with two limit grooves perpendicular to the long side direction of the connecting groove, and a sleeve rod is installed in the two limit grooves.

The depth of the buffer groove is greater than the depth of the slide groove, and a transition slope is provided at the connection between the buffer groove and the slide groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Not only is the processing and assembly process simple, there is no need to dig a long and narrow groove at the position where the semicircular arc contacts the optical device, and then place conductive foam or silver glue in the groove. The conductive gasket, the jack, the partition plate and the ferrule are directly matched to make the conductive gasket fit closely with the base and the optical device.

The bottom surface of the ferrule 5 is provided with two slots that match the connectors of the optical device 2, and the thickness of the ferrule 5 increases from bottom to top. A recessed hole 10 is provided on the outer wall of one side of the ferrule 5. The thickness of the ferrule 5 increases from bottom to top, which not only makes it convenient to insert it into the gap between the conductive gasket 4 and the partition plate 14, but also gradually presses the conductive gasket 4 toward the side close to the socket 3 during the insertion process. The setting of the recessed hole 10 makes it convenient to pull the ferrule 5 out of the installation groove 7.

[0028] The upper cover 6 is detachably covered on the top of the base 1 by screws. The top of the base 1 is provided with a plurality of screw holes for installing screws.

[0029] The implementation principle of this embodiment is: during installation, the connectors of the two optical devices 2 are respectively inserted into the two sockets 3, and the connectors of the two optical devices 2 are placed in the two grooves on the partition plate 14 when inserting, and the conductive gasket 4 on the connector is located on the side of the partition plate 14 close to the socket 3, and then the two card slots at the bottom of the ferrule 5 are aligned with the connectors of the two optical devices 2 and inserted into the gap between the conductive gasket 4 and the partition plate 14, thereby gradually pressing the two conductive gaskets 4 onto the base 1, and finally after the ferrule 5 is installed, the upper cover 6 is fixed with screws.

[0030] Example 2:

[0031] Combine Figure 1-5, based on the embodiment 1, the present embodiment is further improved in that: an auxiliary unit for assisting the insertion and removal of the optical device 2 is installed in the installation groove 7, the auxiliary unit includes a ferrule 5, a base plate 20 installed at the bottom of the installation groove 7, a push plate 8 fixed on the top of the base plate 20 and a clamping assembly installed on the top of the base plate 20 for clamping the optical device 2, the bottom surface of the installation groove 7 is provided with a connecting groove 18 and a movable groove 16 arranged along its length direction, a threaded column 15 is installed in the movable groove 16, and one end of the threaded column 15 extends Into the connecting groove 18, the outer part of the threaded column 15 is screwed with a moving block 17, and the top of the moving block 17 is fixed to the bottom surface of the base plate 20. When the threaded column 15 rotates forward, the base plate 20 moves toward the side close to the partition plate 14. When the threaded column 15 is reversed, the base plate 20 moves to the side away from the partition plate 14. The outer part of the threaded column 15 is sleeved with a linkage gear 21, and the linkage gear 21 is located in the connecting groove 18. The bottom surface of the ferrule 5 is fixed with a rack 11, which is used to drive the linkage gear 21 to rotate while pressing the optical device 2.

[0032] Two limit grooves perpendicular to the long side direction of the connecting groove 18 are provided on the top surface of the base plate 20. A sleeve rod 24 is installed in each of the two limit grooves. The outside of the two sleeve rods 24 is movably sleeved with a slider 19. The clamping assembly includes two movable splints 9 arranged on the top of the base plate 20 and a fixed splint 22 fixed to the top of the base plate 20. The fixed splint 22 is located between the two movable splints 9. Two clamping spaces are formed between the two movable splints 9 and the fixed splint 22. During installation, the two optical devices 2 are respectively placed in the two clamping spaces. The tops of the two sliders 19 are respectively fixed to the bottoms of the two movable splints 9. An extrusion assembly for driving the two movable splints 9 to move toward the side of the fixed splint 22 is provided between the mounting groove 7 and the movable splint 9.

[0033] The extrusion assembly includes two abutment columns 23 respectively fixed on the outer wall of the side away from each other of the two movable splints 9 and guide rails opened on the inner walls of the long sides of the mounting groove 7. The end of the abutment column 23 away from the movable splint 9 extends into the guide rail. The guide rail includes a slide groove 12 and a buffer groove 13 located on the side of the slide groove 12 away from the partition plate 14. The depth of the buffer groove 13 is greater than the depth of the slide groove 12, and a transition slope is provided at the connection between the buffer groove 13 and the slide groove 12. The setting of the transition slope makes it easier for the abutment column 23 to follow the slope from the buffer groove 13 into the interior of the slide groove 12 in the process of following the bottom plate 20 to move toward the side close to the partition plate 14.

[0034] The implementation principle of this embodiment is as follows: when installing the optical device 2, first adjust the position of the bottom plate 20 by toggling the threaded column 15, and place the two optical devices 2 in the two clamping spaces respectively, and then insert one end of the two optical devices 2 into the two jacks 3 in the same manner as in Example 1, and make one end of the two optical devices 2 abut against the outer wall of the push plate 8, and then clamp the ferrule 5 between the conductive gasket 4 and the partition plate 14 in the manner of Example 1, and at the same time as the ferrule 5 is clamped, the rack 11 enters the connecting groove 18 and meshes with the linkage gear 21, so that the linkage gear 21 is continuously driven to rotate forward in the process of the rack 11 gradually entering the connecting groove 18, thereby making the threaded column 15 The movable block 17 then drives the bottom plate 20 to move toward the side close to the partition plate 14 as the threaded column 15 rotates forward, thereby gradually pushing the two optical devices toward the side close to the insertion hole 3, so that the connector can be more tightly inserted into the inside of the insertion hole 3. In the process of the bottom plate 20 moving toward the side close to the partition plate 14, the abutting column 23 will enter the sliding groove 12 from the buffer groove 13, thereby causing the abutting column 23 to move a distance toward the side close to the fixed clamping plate 22, thereby driving the movable clamping plate 9 to move synchronously, thereby clamping the optical device 2 between the movable clamping plate 9 and the fixed clamping plate 22. Later, in the process of the abutting column 23 sliding in the sliding groove 12, the clamping force remains unchanged.

[0035] On the contrary, when removing the optical device 2, the ferrule 5 is pulled upward, the rack 11 then drives the linkage gear 21 to reverse, and the threaded column 15 reverses accordingly, so that the base plate 20 moves to the side away from the partition plate 14. When the abutment column 23 is still in the slide groove 12, the optical device is still clamped in the clamping space, so that the optical device 2 can move synchronously with the base plate 20, and then the connector of the optical device 2 can be gradually pulled out from the jack 3 while pulling out the ferrule 5, until the abutment column 23 slides into the buffer groove 13 and the clamped optical device 2 is released.

[0036] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
