Description

Technical Field

[0001] This utility model belongs to the field of optical communication equipment technology, and in particular relates to an anti-interference TOSA package shell structure. Background Technology

[0002] TOSA is an abbreviation for Transmitter Optical Subassembly, also known as an optical transmitter assembly. It is one of the core components of optical communication equipment (such as optical modules). The core function of TOSA is to convert electrical signals into optical signals, which are then transmitted through optical fibers. It is a key link in the "electro-optical conversion" of optical communication. Align the buckle on the sealing cap with the base and press to achieve initial engagement. Ensure that the upper and lower shells fit together without looseness. Screw in the micro screws in the pre-drilled holes on the edge of the shell to assist in fixing and strengthening. Check the conductive connection between the shell and the grounding pin of the substrate to ensure that the contact resistance is ≤1Ω to avoid interruption of the shielding circuit.

[0003] When existing equipment is in use, because the buckle is located on the outer edge of the device, the splicing surface is prone to small gaps due to tolerances during processing or errors during assembly. This leads to a decrease in the overall sealing effect of the device and increases the probability of dust and other impurities entering. Therefore, we propose an anti-interference TOSA encapsulation shell structure. Utility Model Content

When the positioning rod is inserted into the placement box, it pushes the bottom support plate to move, causing the two first positioning rods to move while simultaneously pulling the second positioning rod to rotate around the outer side of the connecting shaft. The rotation of the second positioning rod pushes the first locking block to insert into the positioning hole inside the positioning rod. The movement of the positioning rod pushes the two first locking blocks to lock the positioning rod in place, preventing the problem that the locking mechanism is located on the outer edge of the device, and the splicing surface is prone to small gaps due to tolerances during processing or errors during assembly. This would reduce the overall sealing effect of the device and increase the probability of dust and other impurities entering.

[0014] 2. This utility model incorporates a knob and a second locking block. Twisting the knob rotates the positioning shaft and the fixing rod, which in turn moves the connecting block. The movement range of the connecting block is limited by a sliding groove. The movement of the connecting block pushes the second locking block outward and inserts it into the limiting groove, locking the positioning block inside the limiting block. Rotating the knob pushes both second locking blocks outward, locking the positioning block inside the limiting block, thus achieving secondary fixation. This prevents unexpected loosening or displacement of the connecting parts due to thermal expansion and contraction during high and low temperature cycles, which could reduce the sealing effect of the device.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 As shown, this utility model is an anti-interference TOSA packaging shell structure, including a placement box 1, and a connection port 101 is fixedly connected to the outer wall of the placement box 1; The inner wall of the placement box 1 is provided with a positioning mechanism 2, which includes a sealing plate 201. An elastic rubber layer is pre-installed on the bottom of the sealing plate 201. After the sealing plate 201 contacts the bottom of the placement box 1, the rubber layer deforms due to compression, thus sealing the gap between the sealing plate 201 and the placement box 1, achieving a sealing effect. The outer wall of the sealing plate 201 is inserted into the inner wall of the placement box 1. Several positioning rods 202 are fixedly connected to the bottom outer wall of the sealing plate 201. The outer walls of the positioning rods 202 are inserted into the inner wall of the placement box 1. The positioning rods 202 help limit the positional relationship between the sealing plate 201 and the placement box 1, preventing accidental displacement of the sealing plate 201 during installation. Positioning holes 2 are provided on the inner wall of the positioning rods 202. 03. Several damping springs 204 are fixedly connected to the inner wall of the placement box 1. A support plate 205 is fixedly connected to the outer wall of the end of the damping spring 204 away from the placement box 1. When the positioning rod 202 moves, it pushes the bottom support plate 205 downward and squeezes the damping spring 204. The elasticity of the damping spring 204 relieves the vibration of the support plate 205. Several first positioning rods 206 are rotatably connected to the outer wall of the support plate 205. A second positioning rod 207 is rotatably connected to the outer wall of the first positioning rod 206 away from the support plate 205. A first locking block 208 is rotatably connected to the outer wall of the second positioning rod 207. When the support plate 205 moves, it drives the first positioning rod 206 to move and pulls the second positioning rod 207. While rotating around the outer side of the first positioning rod 206, it pushes the first locking block 208 to insert it into the positioning hole 203 and locks the positioning rod 202 inside the placement box 1. The outer wall of the second positioning rod 207 away from the first locking block 208 is rotatably connected to the connecting shaft 213. The connecting shaft 213 restricts the position of the second positioning rod 207, allowing the second positioning rod 207 to rotate around the outer side of the connecting shaft 213. The outer wall of the placement box 1 is provided with a fixing mechanism 3. The inner wall of the first locking block 208 is rotatably connected to the first connecting rod 209. The outer wall of the first connecting rod 209 away from the first locking block 208 is rotatably connected to the first slider 210. The movement of the first locking block 208 drives the first connecting rod 209 to rotate around the first locking block 206. While rotating internally, block 208 pushes the first slider 210 to move. Several dampers 211 are fixedly connected to the top outer wall of the first slider 210, and springs 212 are fixedly connected to the outer walls of the dampers 211. The interaction between the dampers 211 and springs 212 alleviates and absorbs the pressure and vibration generated during the movement of the first slider 210, thereby stabilizing the movement of the first locking block 208. The outer wall of the connecting shaft 213 is fixedly connected to the inner wall of the placement box 1. The outer wall of the first locking block 208 is inserted into the inner wall of the positioning hole 203. The outer wall of the first locking block 208 is engaged with the inner wall of the positioning rod 202. The outer wall of the first slider 210 is slidably connected to the inner wall of the placement box 1. The outer wall of the dampers 211 is fixedly connected to the inner wall of the placement box 1.The outer wall of spring 212 is fixedly connected to the outer wall of the first slider 210.

[0021] The fixing mechanism 3 includes a connecting plate 301. The outer wall of the connecting plate 301 is fixedly connected to the outer wall of the sealing plate 201. A positioning block 304 is fixedly connected to the bottom outer wall of the connecting plate 301. Several limiting blocks 302 are fixedly connected to the outer wall of the placement box 1. A limiting groove 303 is formed in the inner wall of the limiting block 302. The limiting groove 303 in the limiting block 302 restricts the movement range of the positioning block 304. A knob 305 is rotatably connected to the outer wall of the positioning block 304. A positioning shaft 306 is fixedly connected to the outer wall of the knob 305 near the positioning block 304. The outer wall of the positioning shaft 306 is rotatably connected to the inner wall of the positioning block 304. A fixing rod 307 is fixedly connected to the outer wall of the positioning shaft 306. The rotation of the knob 305 drives the positioning shaft. While rotating inside the positioning block 304, 306 drives the fixing rod 307 to rotate. The inner wall of the fixing rod 307 is provided with several sliding grooves 308. The inner wall of the sliding groove 308 is slidably connected to the connecting block 309. The outer wall of the connecting block 309 is fixedly connected to the second locking block 310. The rotation of the fixing rod 307 pushes the connecting block 309 to move along the inside of the sliding groove 308, while pushing the second locking block 310 to move. The outer wall of the second locking block 310 is inserted into the inner wall of the limiting groove 303 and locked into the inner wall of the limiting block 302. The movement of the second locking block 310 causes it to insert into the inside of the limiting groove 303 and locks the positioning block 304 inside the limiting block 302, thereby performing secondary fixation.

[0022] A plurality of support rods 311 are rotatably connected to the outer wall of the connecting block 309. A second slider 312 is rotatably connected to the outer wall of the support rod 311 away from the connecting block 309. The movement of the connecting block 309 pushes the support rods 311 to rotate around the outer side of the connecting block 309, while simultaneously pushing the second slider 312 to move. A slide rod 313 is slidably connected to the inner wall of the second slider 312. The outer wall of the slide rod 313 is fixedly connected to the inner wall of the limiting block 302. The slide rod 313 limits the range of movement of the second slider 312, thereby stabilizing the rotation angle of the support rod 311. A pressure spring 314 is fixedly connected to the outer wall of the second slider 312. The outer wall of the pressure spring 314 is fixedly connected to the outer wall of the slide rod 313. The movement of the second slider 312 compresses the pressure spring 314 on the outer side of the slide rod 313. The elasticity of the pressure spring 314 relieves and absorbs the pressure. The pressure of the second slider 312 is applied. The inner wall of the positioning block 304 and the inner wall of the knob 305 are provided with several limiting holes 315. The inner wall of the limiting hole 315 is slidably connected to the third block 317. The outer wall of the third block 317 near the positioning block 304 is fixedly connected to the second pressure spring 316. The outer wall of the second pressure spring 316 is fixedly connected to the inner wall of the positioning block 304. The third block 317 is engaged with the inner wall of the knob 305. During the rotation of the knob 305, the third block 317 is pushed to move along the inside of the limiting hole 315, while the third block 317 squeezes the second pressure spring 316. By utilizing the elasticity of the second pressure spring 316, the third block 317 is automatically pushed to insert into the limiting hole 315 opened inside the knob 305 after the knob 305 stops rotating, and the knob 305 is locked and prevented from rotating.

[0023] One specific application of this embodiment is: When the operator needs to use the equipment, first place the parts into the placement box 1, then place the side of the sealing plate 201 with the rubber layer fixed to its bottom facing down towards the placement box 1. Next, push the sealing plate 201, causing it to move the four positioning rods 202 into the placement box 1. At this point, the sealing plate 201 and the placement box 1 are in close contact, and the rubber layer at the bottom of the sealing plate 201 automatically deforms to seal the gap between the sealing plate 201 and the placement box 1. When the positioning rods 202 are inserted into the placement box 1, they push the bottom support plate 205 to move while simultaneously compressing the damping spring 204 below the support plate 205. The elasticity of the damping spring 204 relieves the pressure on the support plate 205. The pressure and vibration experienced during the movement of the support plate 205 will cause the two first positioning rods 206 to move, while simultaneously pulling the second positioning rod 207 to rotate around the outer side of the connecting shaft 213. The rotation of the second positioning rod 207 will push the first locking block 208 to insert into the positioning hole 203 inside the positioning rod 202, thus locking the positioning rod 202 and preventing its movement. During the movement of the first locking block 208, the first connecting rod 209 will be pulled, causing it to rotate around the first locking block 208, while simultaneously moving the first slider 210. The movement of the first slider 210 will then pull the damper 211 and the spring 212. The cooperation of the two mechanisms alleviates and absorbs the pressure and vibration generated when the first slider 210 moves. During the movement of the sealing plate 201, it drives the connecting plate 301 to move and pushes the positioning block 304 below to insert it into the interior of the limiting blocks 302 on both sides of the placement box 1. The limiting groove 303 inside the limiting block 302 restricts the movement range of the positioning block 304. After ensuring that the sealing plate 201 is locked at the top of the placement box 1, the knob 305 can be turned to drive the positioning shaft 306 to rotate and drive the fixing rod 307 to rotate. The fixing rod 307 pushes the connecting block 309 to move, and the movement range of the connecting block 309 is limited by the sliding groove 308. The movement of the connecting block 309 pushes the connecting block 309 to move. The second locking block 310 moves outward and inserts into the limiting groove 303, locking the positioning block 304 into the limiting block 302 for secondary fixation. During the movement of the connecting block 309, the support rod 311 rotates, simultaneously moving the second slider 312. The movement range of the second slider 312 is limited by the sliding rod 313. Therefore, the sliding rod 313 stabilizes the movement of the second slider 312, allowing the support rod 311 to stably support the movement of the connecting block 309, preventing wobbling. Furthermore, the movement of the second slider 312 compresses the pressure spring 314 connected to the outside of the sliding rod 313, using the elasticity of the pressure spring 314 to alleviate the pressure generated during the movement of the second slider 312.During the rotation of knob 305, multiple third locking blocks 317 are pushed to move along the second pressure spring 316 towards the positioning locking block 304, compressing the second pressure spring 316 fixed inside the positioning locking block 304. After knob 305 stops rotating, the normal release elasticity of the second pressure spring 316 pushes the third locking blocks 317 back to their original positions and locks knob 305, thus preventing knob 305 from rotating due to accidental circumstances, which would reduce the fixing effect. The positioning locking block 304 on the other side is locked inside the limiting block 302 in the same way.
