Technical Field

[0001] This utility model relates to the field of circuit board technology, specifically to a circuit board mounting shell. Background Technology

[0002] A printed circuit board (PCB) is a substrate made of conductive and insulating materials joined together. It is used to connect and support electronic components. It is usually made by the printed circuit board manufacturing process and is also called a printed circuit board. A protective shell is required when mounting a PCB.

[0003] The prior art patent document with publication number CN217957497U provides a circuit board mounting structure, including a bottom shell, a panel mounted on the bottom shell, and a circuit board mounted in the bottom shell. The panel and the bottom shell are connected by a snap-fit ​​method, which reduces the use of screws and overcomes the conflict between screws and nameplates. It simplifies the disassembly and assembly process and reduces the waste of labor and material costs. Through the cooperation of the protrusion and the snap-fit ​​structure, the snap-fit ​​structure is more tightly connected, reducing the loosening of the panel and allowing the internal circuit board to be in a more stable state, so that the circuit board will not vibrate or shake due to the loosening of the panel.

[0004] Although the device has many beneficial effects, the following problems still exist: During the use of the device, the first locking block engages with the second locking block, making it difficult to disassemble after installation and inconvenient for maintenance; secondly, during the use of the device, wiring the circuit board requires drilling holes in the bottom shell, and dust can easily enter through the wiring holes and damage the circuit board, which needs to be improved. In view of this, we propose a circuit board mounting shell. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved:

[0007] To address the problems mentioned above, such as the first card block being connected to the second card block, making disassembly difficult and inconvenient for maintenance, and the need to drill holes in the bottom shell for wiring the circuit board, which allows dust to easily enter through the wiring holes and damage the circuit board, this utility model is proposed.

[0008] Therefore, the purpose of this utility model is to provide a circuit board mounting shell that makes disassembly and assembly simpler and more convenient, facilitates maintenance, and helps to block through holes to prevent dust from entering and damaging the circuit board.

[0009] 2. Technical Solution:

[0010] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0011] A circuit board mounting housing includes a panel, a circuit board body located at the top center of the panel, and a housing at the top of the panel. Mounting components are located on both side walls of the housing. Each mounting component includes a positioning block, a plurality of first springs at the bottom of the inner cavity of the positioning block, a movable block at the top of each first spring, receiving grooves at the bottom of both side walls of the movable block, second springs at the side walls of two receiving grooves, and locking blocks at the other ends of the two second springs. Positioning frames are located on both sides of the top of the panel, with locking slots on both side walls of the inner cavities of the two positioning frames. Multiple through-holes are located on both side walls of the housing, and sealing components are located inside both side walls of the housing. The size of the movable block matches the inner cavity size of the positioning block to prevent dust from entering the housing from inside the positioning block and damaging the circuit board body.

[0012] In a preferred embodiment of the circuit board mounting housing of this utility model, the sealing assembly includes a lead screw, a handle at the top of the lead screw, a movable rod threadedly connected to the outer circumference of the lead screw, and multiple third springs at the bottom of the movable rod. Multiple sealing plates are located at the bottom of the multiple third springs, and each sealing plate has a groove at its bottom. The rebound force of the third springs causes the sealing plates to abut against the wires, facilitating greater stability of the wires and preventing accidental pulling that could cause them to detach.

[0013] In a preferred embodiment of the circuit board mounting shell of this utility model, the size and position of the positioning block match the size and position of the inner cavity of the positioning frame, and the size and position of the card block match the size and position of the card slot.

[0014] In a preferred embodiment of the circuit board mounting housing of the present invention, a lever plate is provided on the top of the side wall of the movable block, and the lever plate extends beyond the side wall of the housing.

[0015] In a preferred embodiment of the circuit board mounting housing of this utility model, cavities are formed inside both side walls of the housing, and the dimensions of the cavities match the dimensions of the moving rod. The cavities facilitate smoother movement of the sealing plate and prevent skewing.

[0016] In a preferred embodiment of the circuit board mounting shell of this utility model, the position of the sealing plate matches the position of the through hole, and the size of the sealing plate is larger than the size of the through hole.

[0017] In a preferred embodiment of the circuit board mounting shell of this utility model, the outer wall of the rotating handle is provided with multiple striped protrusions, and the size of the groove matches the size of the through hole.

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This type of circuit board mounting shell involves splicing the panel and the housing together. The positioning block is inserted into the positioning frame, and the locking block is pressed into the receiving groove by the top of the positioning frame cavity. The second spring's rebound force drives the locking block to move into the slot to complete the locking. When disassembly and maintenance are required, the downward moving block causes the locking block to move inward by the side wall of the positioning block. The positioning block is removed to disassemble the housing. The first spring's rebound force drives the moving block to move upward, and the second spring's rebound force drives the locking block to reset. Disassembly and assembly are simpler and more convenient.

[0021] This type of circuit board mounting shell allows the circuit board body wiring to pass through the through hole. By turning the lever, the lead screw rotates, causing the moving rod to move downwards, which in turn moves the sealing plate downwards. The rebound force of the third spring causes the groove at the bottom of the sealing plate to abut against the wire. The sealing plate moves down to block the through hole without wiring, preventing dust from entering and damaging the circuit board body. Attached Figure Description

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural schematic diagram of one embodiment of a circuit board mounting housing, including:

[0035] Please see Figures 1-5This embodiment of a circuit board mounting housing includes a panel 1, a circuit board body 2 fixedly mounted at the top center of the panel 1, a housing 3 snapped onto the top of the panel 1, and mounting components 4 welded to the two side walls of the housing 3. The mounting components 4 include positioning blocks 401, a plurality of first springs 402 fixedly mounted at the bottom of the inner cavity of the positioning blocks 401, a moving block 403 fixedly mounted on the top of the first springs 402, receiving grooves 404 formed at the bottom of the two side walls of the moving blocks 403, second springs 405 fixedly mounted on the side walls of the two receiving grooves 404, and locking blocks 406 fixedly mounted at the other ends of the two second springs 405. Positioning frames 407 are fixedly mounted on both sides of the top of the panel 1, and locking grooves 408 are formed on the two side walls of the inner cavities of the two positioning frames 407. The two side walls of the housing 3... Multiple through holes 5 are provided on each wall. The inner side walls of the housing 3 are rotatably connected to the sealing components 6. By splicing the panel 1 with the housing 3, the positioning block 401 is inserted into the positioning frame 407. The locking block 406 is pressed into the receiving groove 404 by the top of the inner cavity of the positioning frame 407. The second spring 405 drives the locking block 406 to move into the slot 408 to complete the locking. When disassembly and maintenance are required, the moving block 403 is moved downward to drive the locking block 406 to move inward by the pressure of the side wall of the positioning block 401. The positioning block 401 is removed and the housing 3 is disassembled. The first spring 402 drives the moving block 403 to move upward. The second spring 405 drives the locking block 406 to reset. Disassembly and assembly are simpler and more convenient.

[0036] It is worth noting that, in order to prevent dust from entering through the through hole 5, the sealing component 6 specifically includes a lead screw 601, a handle 602 fixed at the top of the lead screw 601, a moving rod 603 threadedly connected to the outer circumference of the handle 602 and the lead screw 601, a plurality of third springs 604 fixed at the bottom of the moving rod 603, and a plurality of sealing plates 605 fixed at the bottom of the plurality of third springs 604. Each of the sealing plates 605 has a groove 606 at its bottom. When the wiring of the circuit board body 2 is passed through the through hole 5, the lead screw 601 is rotated by turning the handle 602, thereby causing the moving rod 603 to move downward and causing the sealing plates 605 to move downward. The rebound force of the third springs 604 causes the groove 606 at the bottom of the sealing plate 605 to abut against the wire. The sealing plate 605 moves downward and blocks the through hole 5 where there is no wiring, preventing dust from entering and damaging the circuit board body 2.

[0037] Next, in order to improve installation stability, specifically, the size and position of the positioning block 401 are matched with the size and position of the inner cavity of the positioning frame 407, and the size and position of the locking block 406 are matched with the size and position of the locking slot 408. The positioning block 401, which matches the size and position of the inner cavity of the positioning frame 407, prevents the housing 3 from shaking, and the locking block 406, which matches the size and position of the locking slot 408, makes the installation of the housing 3 more stable.

[0038] Meanwhile, in order to facilitate the disassembly and assembly of the housing 3 by the staff, a lever plate 409 is fixedly provided on the top of the side wall of the movable block 403. The lever plate 409 extends beyond the side wall of the housing 3. By extending beyond the side wall of the housing 3, the staff can easily move the movable block 403.

[0039] Furthermore, in order to limit the movement of the moving rod 603, specifically, cavities are opened inside the side walls of both sides of the housing 3. The size of the cavity matches the size of the moving rod 603. By using cavities whose size matches the moving rod 603, the movement of the moving rod 603 is made more stable, and the moving rod 603 is prevented from rotating with the lead screw 601.

[0040] It is worth noting that, in order to prevent dust from entering, the position of the sealing plate 605 is matched with the position of the through hole 5. The size of the sealing plate 605 is larger than the size of the through hole 5. By using the sealing plate 605, which is larger than the through hole 5, dust is prevented from entering through the gap.

[0041] Finally, to facilitate use by staff, the handle 602 is specifically designed with multiple striped protrusions on its outer circumference. The size of the groove 606 matches the size of the through hole 5. The striped protrusions increase friction, making it easier for staff to turn the handle 602. The groove 606, which matches the size of the through hole 5, makes it easier to secure the wires.

[0042] Combination Figures 1-5 The circuit board mounting housing of this embodiment is used in the following specific way:

[0043] 1. When this device is needed for circuit board mounting, the positioning block 401 is inserted into the positioning frame 407 to splice the panel 1 and the housing 3. The locking block 406 is pressed into the receiving groove 404 by the top of the inner cavity of the positioning frame 407. The rebound force of the second spring 405 drives the locking block 406 to move into the slot 408. When disassembly and maintenance are required, the dial plate 409 is moved downward to make the moving block 403 drive the locking block 406 to move inward by the side wall of the positioning block 401. The positioning block 401 is removed and the housing 3 is disassembled. The rebound force of the first spring 402 drives the moving block 403 to move upward. The rebound force of the second spring 405 drives the locking block 406 to reset.

[0044] 2: Pass the wiring of the circuit board body 2 through the through hole 5, turn the lever 602 to make the lead screw 601 rotate and drive the moving rod 603 to move downward, thereby causing the sealing plate 605 to move downward and block the through hole 5 without wiring. The rebound force of the third spring 604 causes the groove 606 at the bottom of the sealing plate 605 to abut against the wire.

[0045] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
