Especially with the large-scale start of 5G network construction, coupled with the rapid development of cloud computing and the batch construction of large-scale data centers, the demand for optical modules has become more urgent;

[0004] However, the existing device loaded with an optical module has a complex structure, a cumbersome plugging and unplugging operation, and an unstable connection state, which affects the efficiency of optical module communication. Therefore, it is urgent to design a quick-insert optical module cage to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a quick-insert optical module cage to solve the above deficiencies in the prior art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A quick-insert optical module cage includes a cage body. A slot is opened on one side of the cage body. An optical module fixing mechanism is arranged in the slot. The optical module fixing mechanism includes an elastic sheet, a slideway and a limiting block. The elastic sheet is arranged on one side of the inner wall of the slot.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below with reference to the accompanying drawings.

[0024] As Figures 1-4 shown, a quick-insert optical module cage provided for an embodiment of the present utility model includes a cage body 1. A notch 16 is provided on one side of the cage body 1. An optical module fixing mechanism 5 is arranged in the notch 16. The optical module fixing mechanism 5 includes an elastic piece 17, a slideway 19 and a limit block 21. The elastic piece 17 is arranged on one side of the inner wall of the notch 16. A protruding piece 18 is arranged on one side of the elastic piece 17. The slideway 19 is fixedly installed on the lower side of the cage body 1 and corresponds to the cage body 1. A slide plate 20 is slidably installed between the slideways 19. The limit block 21 is fixedly installed on the upper side of the slide plate 20. The limit block 21 is located below the elastic piece 17 and the protruding piece 18. The number of the slideways 19 is two. An installation groove 23 is provided on the upper side of the slide plate 20. An elastic snap bead 22 is arranged in the installation groove 23. A clamping groove is provided on one side of the inner wall of the slideway 19. The elastic snap bead 22 is clamped and installed in the clamping groove. A socket 6 is arranged on one side of the cage body 1. Fish-eye feet 4 are arranged on the lower side of the cage body 1. The number of the fish-eye feet 4 is several.

[0025] Specifically, in this embodiment, the cage body 1 is installed on the circuit board through the fish-eye feet 4. When inserting the optical module, the optical module is inserted into the cage body 1 through the socket 6. Among them, the slide plate 20 and the limit block 21 are initially located below the convex piece 18. When the clamping position on the rear side of the optical module contacts the convex piece 18, it will squeeze the convex piece 18. The convex piece 18 can drive the elastic piece 17 to move downward through its arc shape. Then, when the card slot on the clamping position on the rear side of the optical module corresponds to the convex piece 18, the convex piece 18 will rebound through the elastic force of the elastic piece 17 and snap into the card slot, thereby completing the fixation of the optical module. Then, pull the slide plate 20 backward, so that the slide plate 20 drives the limit block 21 to move, so that the limit block 21 contacts the plane on one side of the convex piece 18, thereby being able to limit the convex piece 18 and the elastic piece 17. And at this time, the elastic beads 22 on the slide plate 20 will be snapped into the card slots on the slideway 19 to limit the slide plate 20 and the limit block 21, so that the convex piece 18 and the elastic piece 17 cannot move downward. Among them, when the slide plate 20 and the limit block 21 are located below the convex piece 18, since the lower side of the convex piece 18 is in a hollow state, when the convex piece 18 moves downward, the slide plate 20 and the limit block 21 will not obstruct the convex piece 18. When it is necessary to pull out the optical module, by operating the above steps in reverse, the slide plate 20 and the limit block 21 are reset, and the elastic piece 17 is pressed down to release the lock of the clamping position of the optical module.

[0026] A quick-insert optical module cage provided by the utility model, a heat dissipation mechanism 2 is arranged on the upper side of the cage body 1, installation mechanisms 3 are arranged on both sides of the cage body 1, the heat dissipation mechanism 2 corresponds to the installation mechanism 3, the heat dissipation mechanism 2 includes a heat conduction plate 7 and heat dissipation fins 8, the heat dissipation fins 8 are arranged on the upper side of the heat conduction plate 7, the heat conduction plate 7 is connected to the installation mechanism 3, the heat conduction plate 7 is U-shaped, the installation mechanism 3 includes a fixing plate 9, a sliding groove 10 is opened on the upper side of the fixing plate 9, a slider 12 is slidably installed in the sliding groove 10, a spring 11 is arranged between the slider 12 and the sliding groove 10, a plug rod 13 is arranged on the upper side of the slider 12, the plug rod 13 is L-shaped, a slot 14 is opened on one side of the heat conduction plate 7, slots 14 are opened on both sides at both ends of the heat conduction plate 7, and the number of the plug rods 13 corresponds to the number of the slots 14, the plug rod 13 is movably inserted into the slot 14, a heat conduction groove 15 is opened on the upper side of the cage body 1, the number of the heat conduction grooves 15 is several, and the heat conduction grooves 15 correspond to the heat conduction plate 7.

[0027] In another embodiment provided by the present utility model, a plurality of heat-conducting contact plates are arranged on the lower side of the heat-conducting plate 7. The heat-conducting contact plates pass through the heat-conducting grooves 15 to contact the optical module. The heat generated by the optical module can be absorbed through the heat-conducting contact plates and the heat-conducting plate 7, and then, the heat is dissipated through the heat-dissipating fins 8. When it is necessary to disassemble the heat-dissipating mechanism for cleaning or replacement, by pulling the insertion rod 13 backward, the insertion rod 13 drives the slider 12 to move along the sliding groove 10. The movement of the insertion rod 13 can disengage from the slot 14 on the heat-conducting plate 7, thereby being able to release the fixation of the heat-conducting plate 7, facilitating the staff to disassemble the heat-dissipating mechanism. During installation, by operating the above steps in reverse, the installation can be completed.

[0028] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
