Description

Technical Field

[0001] This utility model relates to the field of circuit board mounting technology, and in particular to a circuit board mounting and positioning structure. Background Technology

[0002] A circuit board, also known as a PCB, is a fundamental component used in electronic devices. Common mounting methods for circuit boards include screw mounting, surface mounting, through-hole mounting, embedded mounting, and magnetic mounting. When a circuit board is inserted into a slot inside a device housing, there will be a certain gap. To prevent the circuit board from wobbling, it is usually further secured with screws.

[0003] After the circuit board is further secured with screws, stress deformation will occur at the screw mounting points after long-term use, causing cracks or even damage to the circuit board, which will affect the normal use of the circuit board. Therefore, a circuit board mounting and positioning structure is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a circuit board mounting and positioning structure to solve the problem mentioned in the background art, where after the circuit board is further fixed with screws, stress deformation will occur at the screw mounting part after long-term use, causing cracks or even damage to the circuit board, thus affecting the normal use of the circuit board.

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

[0006] This utility model is a circuit board mounting and positioning structure, comprising:

[0007] A connecting component, comprising a U-shaped mounting block and a slot, wherein the U-shaped mounting block is fixed inside the equipment housing by screws, and the slot is formed on both sides inside the U-shaped mounting block;

[0008] The damage prevention component includes a support plate, a first through hole, a T-shaped connecting block, a T-shaped rubber block, and a round spring. The support plate is fixed to the outer side of the U-shaped mounting block, the first through hole is opened in the inner bottom surface of the U-shaped mounting block, the T-shaped connecting block is inserted into the first through hole, the T-shaped rubber block is screwed to one end of the T-shaped connecting block, and the round spring is sleeved on the outer side of the T-shaped connecting block.

[0009] Furthermore, the damage prevention component also includes a mounting plate, which is fixed to one side of the support plate, and the support plate is fixed to the outside of the U-shaped mounting block by the mounting plate.

[0010] Furthermore, the support plate is located between the U-shaped mounting block and the equipment housing, the round spring is located between the U-shaped mounting block and the equipment housing, with one end fixed to the outer side of the U-shaped mounting block and the other end fixed to the T-shaped connecting block, and the T-shaped rubber block is located inside the U-shaped mounting block.

[0011] Furthermore, the connection assembly also includes a circuit board, which is inserted into the slot and positioned above the T-shaped rubber block.

[0012] Furthermore, it also includes a limiting component, which includes a second through hole, a pull rod, and a limiting block. The second through hole is opened at both ends of the support plate, the limiting block is inserted into the second through hole, and one end is movably connected to the side of the T-shaped connecting block. The pull rod is fixed to the other end of the limiting block.

[0013] Furthermore, the limiting assembly also includes a rectangular spring and a limiting plate. The limiting plate is fixed to one end of the limiting block near the T-shaped connecting block. The rectangular spring is sleeved in the middle section of the limiting block, with one end fixed to the side of the support plate and the other end fixed to the side of the limiting plate.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model, through the inclusion of a damage-prevention component, secures the mounting plate on the support plate to the outside of the U-shaped mounting block with screws. The support plate is then fitted against the inside of the equipment housing, and the U-shaped mounting block is fixed to the inside of the housing with long screws. Next, one hand presses down on the T-shaped rubber block, causing it to adhere to the bottom inner surface of the U-shaped mounting block. The other hand inserts the circuit board from one end of the slot until it is fully inserted into the U-shaped mounting block. At this point, the spring contracts, moving the T-shaped connecting block and causing the T-shaped rubber block to adhere to the bottom of the circuit board, thus securing the circuit board firmly within the slot. This design avoids damage to the circuit board caused by stress deformation when using screws to position it.

[0016] II. This utility model, through the setting of the limiting component, allows for quick insertion of the circuit board. Before insertion, one hand pulls the lever, causing the limiting block to move along the second through hole, moving the limiting block outwards from the U-shaped mounting block. At this time, the rectangular spring contracts, causing the limiting plate to move. The other hand presses down on the T-shaped rubber block, causing the circular spring to extend, and the T-shaped connecting block to move away from the first through hole. Then, the lever is released, the rectangular spring extends, causing the limiting block to move again, so that the limiting block is locked on the disc at the lower end of the T-shaped connecting block. After the circuit board is inserted into the slot, the lever is pulled again, causing the limiting block to disengage from the T-shaped connecting block. At this time, the circular spring contracts, causing the T-shaped rubber block to press against the circuit board. This setting facilitates quick insertion of the circuit board.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] Please see Figure 1-6 As shown, this embodiment is a circuit board mounting and positioning structure, including:

[0030] The connecting assembly includes a U-shaped mounting block 10 and a slot 11. The U-shaped mounting block 10 is fixed inside the equipment housing by screws, and the slot 11 is opened on both sides inside the U-shaped mounting block 10. The connecting assembly also includes a circuit board 12, which is inserted into the slot 11 and is located above the T-shaped rubber block 24.

[0031] The U-shaped mounting block 10 provides support, the slot 11 provides positioning, and the circuit board 12 is an indispensable core component in modern electronic devices.

[0032] The damage prevention component includes a support plate 20, a first through hole 22, a T-shaped connecting block 23, a T-shaped rubber block 24, and a round spring 25. The support plate 20 is fixed to the outer side of the U-shaped mounting block 10. The first through hole 22 is opened on the inner bottom surface of the U-shaped mounting block 10. The T-shaped connecting block 23 is inserted into the first through hole 22. The T-shaped rubber block 24 is screwed to one end of the T-shaped connecting block 23. The round spring 25 is sleeved on the outside of the T-shaped connecting block 23.

[0033] The damage prevention component also includes a mounting plate 21, which is fixed to one side of the support plate 20, and the support plate 20 is fixed to the outside of the U-shaped mounting block 10 through the mounting plate 21.

[0034] The support plate 20 is located between the U-shaped mounting block 10 and the equipment housing. The coil spring 25 is located between the U-shaped mounting block 10 and the equipment housing, with one end fixed to the outer side of the U-shaped mounting block 10 and the other end fixed to the T-shaped connecting block 23. The T-shaped rubber block 24 is located inside the U-shaped mounting block 10.

[0035] The support plate 20 provides support and creates a gap between the equipment casing and the U-shaped mounting block 10, facilitating the movement of the T-shaped connecting block 23. The mounting plate 21 is used to fix the support plate 20. The first through hole 22 facilitates the movement of the T-shaped connecting block 23. The T-shaped rubber block 24 serves as a connector, and the round spring 25 has a retraction function.

[0036] Working principle:

[0037] Fix the mounting plate 21 on the support plate 20 to the outside of the U-shaped mounting block 10 with screws. Then, fit the support plate 20 into the inside of the equipment housing and fix the U-shaped mounting block 10 into the inside of the equipment housing with long screws. Then, press down the T-shaped rubber block 24 with one hand so that the T-shaped rubber block 24 fits into the inner bottom surface of the U-shaped mounting block 10. With the other hand, insert the circuit board 12 from one end of the slot 11 until it is fully inserted into the U-shaped mounting block 10. At this time, the round spring 25 contracts, which drives the T-shaped connecting block 23 to move, causing the T-shaped rubber block 24 to fit into the bottom of the circuit board 12 and press the circuit board 12 against the slot 11.

[0038] This step can prevent damage to the circuit board 12 caused by stress deformation due to the use of screws to position the circuit board 12.

[0039] Please see Figure 6 This embodiment, based on the above embodiments, further includes:

[0040] The limiting component includes a second through hole 30, a pull rod 31 and a limiting block 32. The second through hole 30 is opened at both ends of the support plate 20. The limiting block 32 is inserted into the second through hole 30 and one end is movably connected to the side of the T-shaped connecting block 23. The pull rod 31 is fixed to the other end of the limiting block 32.

[0041] The limiting assembly also includes a rectangular spring 33 and a limiting plate 34. The limiting plate 34 is fixed to one end of the limiting block 32 near the T-shaped connecting block 23. The rectangular spring 33 is sleeved in the middle section of the limiting block 32, with one end fixed to the side of the support plate 20 and the other end fixed to the side of the limiting plate 34.

[0042] The second through hole 30 facilitates the movement of the limiting block 32, the pull rod 31 facilitates hand operation of the limiting block 32, the limiting block 32 plays a limiting role, the rectangular spring 33 has a compression function, and the limiting plate 34 plays a connecting role.

[0043] Working principle:

[0044] Before inserting the circuit board 12, pull the lever 31 with one hand to move the limiting block 32 along the second through hole 30, causing the limiting block 32 to move outward of the U-shaped mounting block 10. At this time, the rectangular spring 33 contracts, causing the limiting plate 34 to move. With the other hand, press down on the T-shaped rubber block 24 to extend the round spring 25, causing the T-shaped connecting block 23 to move away from the first through hole 22. Then release the lever 31, and the rectangular spring 33 extends, causing the limiting block 32 to move, so that the limiting block 32 is stuck on the disc at the lower end of the T-shaped connecting block 23. After the circuit board 12 is inserted into the slot 11, pull the lever 31 again to disengage the limiting block 32 from the T-shaped connecting block 23. At this time, the round spring 25 contracts, causing the T-shaped rubber block 24 to press against the circuit board 12.

[0045] This step facilitates quick insertion of circuit board 12.
