Description

Technical Field

[0001] This utility model relates to, but is not limited to, the field of optical module housing technology. Specifically, it relates to a quick-release structure for a grating beam splitter housing. Background Technology

[0002] A grating beam splitter module typically consists of a light emitting device, a light receiving device, functional circuits, and an optical (electrical) interface. At the emitting end, the driver chip processes the original electrical signal and then drives a semiconductor laser (LD) or light-emitting diode (LED) to emit a modulated light signal. At the receiving end, after the light signal enters, it is converted into an electrical signal by a photodetector diode and then output as an electrical signal after passing through a preamplifier.

[0003] Existing grating beam splitter module housings generally lack pre-alignment structures, requiring repeated alignment during assembly and often relying on screws for fixation. Disassembly and assembly require tools and involve cumbersome procedures. Therefore, a quick-release structure for the grating beam splitter module housing that requires no additional tools is designed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a quick-release structure for the housing of a grating beam splitter module.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a quick-release structure for a grating beam splitter housing, including a housing, an optical fiber interface at the front end of the housing, and a circuit board inside the housing. The housing includes a base, a top cover, and a housing connection structure for connecting the base and the top cover. The housing connection structure includes a mounting plate, a control plate, a retaining ring, and hooks that cooperate with the retaining ring. The mounting plate is disposed on the left and right sides of the base, the control plate is disposed between the base and the retaining ring, and the hooks are disposed on the left and right sides of the top cover.

[0007] Preferably, the base is disposed below the circuit board, and the top cover is disposed above the circuit board, the shape of the top cover being adapted to the base.

[0008] Preferably, a positioning block is fixed at the bottom of the top cover, and a positioning groove adapted to the positioning block is opened inside the base, and the positioning block is inserted into the positioning groove.

[0009] Preferably, the upper cover has mounting grooves on both sides for mounting the hook block, and the rear end of the hook block is screwed to the upper cover.

[0010] Preferably, the mounting plate is screwed to the base, and rotating columns are fixed on both sides of the upper end of the control plate. The upper end of the mounting plate is provided with a rotating groove for the rotating columns to rotate, and a rubber washer is fixed on the inner wall of the rotating groove.

[0011] Preferably, a connecting rod is fixed to the bottom end of the buckle, and a connecting groove for the connecting rod to rotate is provided in the middle of the control plate. The connecting rod passes through the connecting groove and is rotatably connected to the control plate.

[0012] Preferably, a limit block is fixed to the bottom surface of the control plate, the end of the limit block is designed to protrude, and a limit frame adapted to the limit block is fixed to the inner side of the mounting plate.

[0013] Preferably, the upper end of the limiting frame has a "petal" shape design, and the limiting frame is made of stainless steel.

[0014] Preferably, the outer shell is made of high thermal conductivity aluminum alloy, and the inner wall of the base is provided with microgrooves, which are either straight grooves or herringbone grooves.

[0015] Preferably, a spring is fixed at the rear end of the optical fiber interface. The spring has a raised design, and a slot adapted to the spring is provided on the surface of the top cover.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention uses precise pre-alignment of the positioning block and the positioning groove as a starting point, followed by lifting and pressing down the control plate with one hand. The buckle hooks the hook block under the action of leverage, and the limiting frame elastically clamps the limiting block to achieve self-locking. The entire disassembly and assembly process does not require any tools. Lifting the control plate again will instantly unlock the module. This improves the speed of disassembly and assembly of the grating beam splitter housing and solves the problem that existing grating beam splitter housings generally lack a pre-positioning structure and require tools and complicated steps for disassembly and assembly.

[0033] like Figure 1-5As shown, this utility model provides a quick-release structure for the housing of a grating beam splitter module, including a housing, an optical fiber interface 13 at the front end of the housing, and a circuit board 14 inside the housing. The housing includes a base 11, a top cover 12, and a housing connection structure 2 for connecting the base 11 and the top cover 12. The housing connection structure 2 includes a mounting plate 21, a control plate 22, a retaining ring 23, and a hook block 24 that cooperates with the retaining ring 23. The mounting plate 21 is disposed on the left and right sides of the base 11, the control plate 22 is disposed between the base 11 and the retaining ring 23, and the hook block 24 is disposed on the left and right sides of the top cover 12.

[0034] Furthermore, in this embodiment, the base 11 is disposed below the circuit board 14, and the upper cover 12 is disposed above the circuit board 14. The shape of the upper cover 12 is adapted to the base 11 to form upper and lower protection for the circuit board 14, and better cooperation is achieved through shape adaptation.

[0035] In this embodiment, a positioning block 123 is fixed at the bottom of the upper cover 12, and a positioning groove 111 adapted to the positioning block 123 is opened inside the base 11. The positioning block 123 is inserted into the positioning groove 111. The positioning block 123 and the positioning groove 111 cooperate to provide a pre-positioning function, ensuring that the upper cover 12 and the base 11 are quickly aligned before being fastened, avoiding assembly offset, and providing a structural reference for the subsequent locking of the buckle 23 and the hook block 24.

[0036] In this embodiment, the upper cover 12 has mounting grooves 122 on both sides for mounting the hook block 24. The rear end of the hook block 24 is screwed to the upper cover 12. The screw connection ensures that the hook block 24 remains stable during repeated disassembly and assembly.

[0037] In this embodiment, the mounting plate 21 is screwed to the base 11 to form a support frame. Rotating columns 221 are fixed on both sides of the upper end of the control plate 22. The upper end of the mounting plate 21 is provided with a rotating groove 212 for the rotating columns 221 to rotate. The rotating columns 221 and the rotating groove 212 form the rotation fulcrum of the control plate 22, realizing the lever-type opening and closing of the buckle 23. A rubber washer is fixed on the inner wall of the rotating groove 212 to prevent the control plate 22 from shaking when not in operation.

[0038] In this embodiment, a connecting rod 231 is fixed at the bottom of the buckle 23, and a connecting groove 223 for the connecting rod 231 to rotate is provided in the middle of the control plate 22. The connecting rod 231 passes through the connecting groove 223 and is rotatably connected to the control plate 22, which converts the linear motion of the buckle 23 into the rotational motion of the control plate 22. This allows for one-handed operation of the buckle 23, which can simultaneously drive the locking / releasing of both sides, thus improving the efficiency of disassembly and assembly.

[0039] In this embodiment, a limiting block 222 is fixed on the bottom surface of the control plate 22. The end of the limiting block 222 is designed to protrude. A limiting frame 211 that is adapted to the limiting block 222 is fixed on the inner side of the mounting plate 21. After the buckle 23 and the hook block 24 are connected, the limiting block 222 and the limiting frame 211 cooperate to restrict the control plate 22 to the inner side of the mounting plate 21, so as to prevent the control plate 22 from moving freely.

[0040] In this embodiment, the upper end of the limiting frame 211 is designed in a "petal" shape. The limiting frame 211 is made of stainless steel. When the protruding part of the end of the limiting block 222 is inserted into the limiting frame 211, the limiting frame 211 is stretched open based on its shape. Under the action of the material of the limiting frame 211, its elastic force makes the limiting frame 211 stick tightly to the outer surface of the limiting block 222, thereby temporarily limiting the position of the control plate 22.

[0041] In this embodiment, the outer shell is made of high thermal conductivity aluminum alloy. The aluminum alloy material efficiently conducts heat from the circuit board 14 to the outer shell, achieving passive heat dissipation. The inner wall of the base 11 is provided with microgrooves 112. The microgrooves 112 are either straight grooves or herringbone grooves. The microgrooves 112 increase the heat dissipation surface area. The straight groove / herringbone groove design can guide airflow to form micro-convection, further improving heat dissipation efficiency. The herringbone groove can also enhance the structural strength.

[0042] In this embodiment, a spring 131 is fixed at the rear end of the optical fiber interface 13. The spring 131 has a protruding design. A slot 121 adapted to the spring 131 is opened on the surface of the upper cover 12. The optical fiber interface is connected to the upper cover 12 through the spring 131 and the slot 121.

[0043] Specifically, based on the existing grating beam splitter structure, the circuit board 14 is placed horizontally into the base 11. All optical fibers and ribbon cables are confirmed to be correctly plugged in. The micro-grooves 112 on the inner wall of the base 11 are checked to ensure that there are no foreign objects blocking the heat dissipation slots. The pre-insertion positioning, lifting of the control board, hooking of the buckle with the hook block, pressing down self-locking, and unlocking of the lifted outer shell are performed in the disassembly and assembly steps.

[0044] Detailed disassembly and assembly steps: Align the positioning block 123 of the upper cover 12 with the positioning groove 111 in the base 11, press the upper cover 12 vertically down until the positioning block 123 is fully inserted into the positioning groove 111, and the bottom surface of the upper cover 12 is in contact with the upper surface of the base 11. At this time, the upper cover 12 and the base 11 have formed a preliminary alignment.

[0045] Manually lift the tail end of the control plate 22. The control plate 22 swings upward with the rotating column 221 as the fulcrum. The connecting rod 231 rotates in the connecting groove 223 of the control plate 22, driving the buckle 23 to move and rotate towards the hook block 24. The front end of the buckle 23 gradually approaches and hooks the hook block 24. At this time, the buckle 23 is hooked on the hook block 24, but it is not yet locked. Press down the tail end of the control plate 22 to make it swing downward. Since the buckle 23 has hooked the hook block 24, it is pulled tight and pressed down to form a lock. The protruding end of the limit block 222 is inserted into the limit frame 211. The limit frame 211 is elastically clamped to prevent rebound and complete the self-locking.

[0046] After confirming that all the buckles 23 on both sides are fully engaged, insert the fiber optic plug into the front fiber optic interface 13. The protruding spring 131 at the rear of the interface will automatically snap into the slot 121 of the top cover 12. Use the included screw to pass through the reserved hole at the tail end of the top cover 12 and screw it into the corresponding threaded hole of the base 11.

[0047] When disassembly is required, lift the control board 22 with one hand and gently pull the limit block 222 outward to disengage it from the limit frame 211. The hook block 24 will disengage from the buckle 23, and the upper cover 12 will be unlocked from the base 11. Lift the upper cover 12 vertically upward, and the positioning block 123 will disengage from the positioning groove 111, thus completely separating the upper cover 12 from the base 11. When unplugging the fiber optic plug, first press the spring piece 131 to release the slot 121, and then pull it out smoothly. The rubber gasket provides damping, and the control board 22 will not droop automatically, making it easy for one person to operate. After locking, the aluminum alloy shell continuously dissipates heat through a high thermal conductivity path and micro-grooves 112, without the need for additional heat sinks.

[0048] It should be noted that the shape of the outer shell is adapted to the actual structural shape of the grating beam splitter module. Therefore, the size of the outer shell connection structure 2 also needs to be adapted. In addition, considering the usage environment, multiple outer shell connection structures 2 can be used for connection to avoid the situation where the top cover 12 and the base 11 become loose.

[0049] The base 11, top cover 12, slot 121, positioning block 123, fiber optic interface 13, spring 131, circuit board 14, outer shell connection structure 2, mounting plate 21, limiting frame 211, control board 22, rotating column 221, limiting block 222, connecting groove 223, buckle 23, connecting rod 231, hook block 24 and other components of this utility model are all general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
