[0002] Optical modules are composed of optoelectronic devices, functional circuits and optical interfaces. Optoelectronic devices include transmitting and receiving parts. The function of optical modules is to convert electrical signals into optical signals at the transmitting end. After transmission through optical fiber, the receiving end converts the optical signals into electrical signals. At present, QSFP28 type modules are the representatives of packaged optical modules. They can support multiple channels for transmission at the same time. The heat generated by multi-channel transmission during operation is also greater. In addition, the ideal operating temperature range of optical modules is between 0-70 degrees Celsius. Therefore, there is room for improvement in how to ensure that the optical modules operate in a reasonable temperature range. Utility Model Content

[0003] The utility model aims to provide an optical module with an adjustable heat dissipation structure to solve the above problems existing in the prior art.

[0004] The technical problem to be solved by the utility model is to provide an improved operating temperature range of an optical module.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] An optical module with an adjustable heat dissipation structure comprises a base, a shell is arranged on the top of the base, a cover is detachably installed on the top of the shell, a module mainboard is arranged in the shell, a lifting frame is fixedly installed on the top of the base, a long strip of sliding bar is arranged on the inner wall of the lifting frame, sliding grooves are provided on both sides of the outer wall of the shell, the shell is slidably connected with the sliding bar through the sliding grooves, an insulating sealing pad is fixedly installed at the top center of the base, and a heat dissipation cavity matching the insulating sealing pad is provided at the inner center of the shell.

[0007] The beneficial effects of the utility model are as follows: the shell can be raised and lowered on the lifting frame, and when the operating environment temperature of the optical module is high, the shell is raised by means of the sliding strip on the inner wall of the lifting frame cooperating with the sliding groove on the outer wall of the shell, so that the bottom of the shell is suspended in the air, and the characteristic of a heat dissipation cavity provided in the shell helps to dissipate the heat inside the shell to avoid heat accumulation, thereby reducing the overall operating temperature of the optical module; when the operating environment temperature of the optical module is low, the shell descends on the lifting frame, and when the shell is in contact with the base, the insulating sealing pad seals the heat dissipation cavity to avoid the optical module from having an operating temperature that is too low.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, a supporting assembly is fixedly installed on the top of the base, and the supporting assembly consists of a closed threaded seat, a threaded rotating plate and a threaded rod, and the closed threaded seat is fixedly installed on the top of the base, the threaded rod is threadedly installed on the inside of the closed threaded seat, and the threaded rotating plate is threadedly installed on the outside of the threaded rod, and the threaded rotating plate is in the shape of a "9".

[0010] The beneficial effect of adopting the above-mentioned further scheme is that the threaded rod can rotate inside the closed threaded seat, so that the threaded rotating plate threadedly installed on the outside of the threaded rod can rotate and rise and fall. When the shell is raised, the threaded rotating plate loses its spatial restriction. At the same time, the shape of the threaded rotating plate is in the shape of a " ", which enables the protruding end of the threaded rotating plate to extend to the bottom of the shell for support, so as to ensure the stability of the shell being suspended in the air and the upper end of the base.

[0011] Furthermore, a positioning assembly is fixedly installed on the top of the cover plate, and the positioning assembly includes a connecting rod, a spring tube, a telescopic spring and a block, and the connecting rod is fixedly installed on the top of the cover plate, and the spring tube is fixedly installed on the top of the connecting rod, one end of the two telescopic springs is fixedly installed inside the spring tube, and the other end extends to the inside of the spring tube and is fixedly installed with a block, an empty slot is opened on the top of the lifting frame, and the shape of the empty slot is square, and the empty slot provides lifting space for the positioning assembly, and two plug-in socket bodies are fixedly installed on the top of the lifting frame, and the two opposite sides of the two plug-in socket bodies are provided with a card slot, and the shape of the card slot is adapted to the card block.

[0012] The beneficial effect of adopting the above further scheme is that when the card block is pressed, the telescopic spring will be squeezed and contracted to the inside of the spring tube, and when the card block loses its limit, the telescopic spring will drive the card block to reset and pop out. An empty slot is provided inside the lowering frame to match the positioning component. When the shell is lifted and lowered under the action of the sliding bar and the sliding slot, the positioning component connected to the shell will also be lifted and moved, and the empty slot provides space for movement. As the shell continues to rise, the positioning component will pass through the preset empty slot inside the lifting frame, and the card block and the telescopic spring will lose their limit after moving out of the empty slot, and the card block will be driven to pop into the card slot under the action of the telescopic spring reset, so as to limit the two ends of the bottom of the shell.

[0013] Furthermore, a dust cover is installed at the heat dissipation cavity.

[0014] The beneficial effect of adopting the above further solution is that the dust cover prevents the heat dissipation cavity from opening after the shell is raised, thereby preventing dust and flying insects from entering the shell.

[0015] Furthermore, the insulating sealing pad is made of silicone.

[0016] The beneficial effect of adopting the above further solution is that the insulating sealing pad made of silicone material can better block the transfer of temperature. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0025] like Figures 1 to 5 As shown, embodiment 1 of the utility model is an optical module with an adjustable heat dissipation structure, comprising a base 1, a shell 2 is arranged on the top of the base 1, a cover plate 3 is detachably installed on the top of the shell 2, a module mainboard 8 is arranged in the shell 2, a lifting frame 5 is fixedly installed on the top of the base 1, a long strip of sliding bar is arranged on the inner wall of the lifting frame 5, sliding grooves are provided on both sides of the outer wall of the shell 2, the shell 2 is slidably connected with the sliding bar through the sliding grooves, an insulating sealing pad 9 is fixedly installed at the top center of the base 1, and a heat dissipation cavity 21 matching the insulating sealing pad 9 is opened at the inner center of the shell 2.

[0026] The shell 2 can be raised and lowered on the lifting frame 5. When the operating environment temperature of the optical module is high, the shell 2 is raised by the sliding bar on the inner wall of the lifting frame 5 and the sliding groove on the outer wall of the shell 2, so that the bottom of the shell 2 is suspended in the air. Combined with the characteristic of a heat dissipation cavity 21 opened in the shell 2, the heat inside the shell 2 is helped to dissipate, avoiding heat accumulation, thereby reducing the temperature of the overall operation of the optical module.

[0027] When the operating environment temperature of the optical module is low, the housing 2 descends on the lifting frame 5, and when the housing 2 fits with the base 1, the insulating sealing pad 9 seals the heat dissipation cavity 21 to prevent the optical module from operating at too low a temperature.

[0028] The heat dissipation cavity 21 of the housing 2 is opened and closed by rising and falling of the housing 2, so that the optical module works in a reasonable temperature range.

[0029] Embodiment 2 of the utility model is an optical module with an adjustable heat dissipation structure. Based on Embodiment 1, a supporting assembly 7 is fixedly installed on the top of the base 1. The supporting assembly 7 consists of a closed threaded seat 72, a threaded rotating plate 71 and a threaded rod 70. The closed threaded seat 72 is fixedly installed on the top of the base 1, the threaded rod 70 is threadedly installed on the inside of the closed threaded seat 72, the threaded rotating plate 71 is threadedly installed on the outside of the threaded rod 70, and the threaded rotating plate 71 is in the shape of a "9".

[0030] The threaded rod 70 can rotate inside the closed threaded seat 72, so that the threaded rotating plate 71 threadedly installed on the outside of the threaded rod 70 can rotate and rise and fall. When the shell 2 is raised, the threaded rotating plate 71 loses its spatial restriction. At the same time, the shape of the threaded rotating plate 71 is in the shape of a "9", which can make the protruding end of the threaded rotating plate 71 extend to the bottom of the shell 2 for support, so as to ensure the stability of the shell 2 suspended in the air and the upper end of the base 1.

[0031] Embodiment 3 of the utility model is an optical module with an adjustable heat dissipation structure. On the basis of embodiment 1 or 2, a positioning component 4 is fixedly installed on the top of the cover plate 3, and the positioning component 4 includes a connecting rod 40, a spring tube 41, a telescopic spring 42 and a clamping block 43, and the connecting rod 40 is fixedly installed on the top of the cover plate 3, and the spring tube 41 is fixedly installed on the top of the connecting rod 40, one end of the two telescopic springs 42 is fixedly installed in the interior of the spring tube 41, and the other end extends to the interior of the spring tube 41 and is fixedly installed with a clamping block 43, an empty slot is opened on the top of the lifting frame 5, and the shape of the empty slot is square, and the empty slot provides lifting space for the positioning component 4, and two plug-in socket bodies 6 are fixedly installed on the top of the lifting frame 5, and the two opposite sides of the two plug-in socket bodies 6 are provided with a clamping slot, and the shape of the clamping slot is adapted to the clamping block 43.

[0032] When the block 43 is pressed, the telescopic spring 42 is squeezed and shrinks into the spring tube 41 . When the block 43 loses its limit position, the telescopic spring 42 drives the block 43 to return to its original position and pop out.

[0033] The lowering frame 5 has an empty slot inside for the positioning assembly 4. When the housing 2 is lifted and lowered by the slide bar 2 and the slide slot, the positioning assembly 4 connected to the housing 2 will also be lifted and lowered, and the empty slot provides space for movement.

[0034] As the shell 2 continues to rise, the positioning assembly 4 will pass through the preset empty slot inside the lifting frame 5, and the block 43 and the telescopic spring 42 will lose their limit after moving out of the empty slot, and the block 43 will bounce into the slot under the action of the resetting of the telescopic spring 42, thereby limiting the two ends of the bottom of the shell 2.

[0035] Embodiment 4 of the present utility model is an optical module with an adjustable heat dissipation structure. Based on any one of embodiments 1 to 3, a dust cover 10 is installed at the heat dissipation cavity 21 .

[0036] The dust cover 10 prevents the heat dissipation cavity 21 from opening when the housing 2 is raised, thereby preventing dust and flying insects from entering the housing 2 .

[0037] Embodiment 5 of the present utility model is an optical module with an adjustable heat dissipation structure. Based on any one of embodiments 1 to 4, the material of the insulating sealing pad 9 is silicone.

[0038] The insulating sealing pad 9 made of silicone material can better block the transfer of temperature.
