Description

Technical Field

[0001] This utility model relates to the field of circuit boards, and in particular to a quick-connect structure for circuit boards. Background Technology

[0002] Chinese patent CN210610076U discloses a shockproof quick-release integrated circuit board, including a circuit board body and a base frame. Guide rods are fixedly connected to the four corners of the upper end of the base frame. L-shaped moving blocks are slidably connected to the guide rods, and the L-shaped moving blocks on the left and right sides are symmetrically arranged. A first spring is sleeved on the guide rod at the L-shaped moving blocks. A locking block is connected to the inner side of the L-shaped moving block through a second spring. The sides of the locking blocks on the left and right sides that are close to each other are provided with a slot for locking the circuit board body. A threaded hole communicating with the slot is provided at the top of the slot. A screw is threadedly connected to the threaded hole. A pressure plate is provided at the bottom of the screw to press the circuit board body tightly against the bottom of the slot.

[0003] Although the above structure uses a pressure plate to press the circuit board body against the bottom of the slot instead of the original method of fixing the circuit board body with bolts, making it easier to assemble and disassemble the circuit board body, if the distance the screw rotates and descends is too small, the clamping force on the circuit board body will be insufficient, causing the circuit board body to easily fall out of the slot; if the distance the screw rotates and descends is too large, the clamping force of the pressure plate on the circuit board body will be too large, damaging the circuit board body. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies where, when installing a circuit board into a slot, excessive or insufficient screw descent distance can affect the installation of the circuit board. The former can lead to damage to the circuit board, while the latter can result in unstable installation. This invention provides a quick-installation structure that facilitates convenient and stable circuit board installation.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0006] A quick-installation structure for a circuit board includes a mounting bracket, in which a circuit board is installed. The mounting bracket includes a fixing frame with an opening at one end, and a slot communicating with the opening and into which the circuit board is inserted. The opening of the fixing frame is provided with a cover that closes the opening of the fixing frame when the circuit board is inserted into the slot. A limiting structure is provided between the two side walls of the opening end of the fixing frame and the two side walls of the cover to limit the position of the cover when it is installed at the opening of the fixing frame.

[0007] Using the above solution, the slots for inserting circuit boards within the mounting frame allow for stable installation of the circuit boards. The cover can be moved to the opening of the mounting frame after the circuit board is inserted into the slot. A limiting structure between the opening of the mounting frame and the cover restricts the position of the cover when it moves to the opening and closes, thus limiting the circuit board and enabling its installation. Since the circuit board installation process only requires inserting the circuit board into the slot of the mounting frame and then moving the cover to the opening and limiting the cover with the limiting structure, the installation of the circuit board is faster and more stable.

[0008] Preferably, the limiting structure includes locking blocks respectively provided on both sides of the opening end of the fixing frame and buckles provided on both sides of the cover, which engage with the locking blocks when the cover closes the opening end of the fixing frame. The end of the buckle near the closing end of the cover is provided with an guiding component to facilitate the buckle to deform under the pressure of the locking block when the cover is installed to the opening end of the fixing frame. The end of the buckle away from the closing end of the cover is provided with an unlocking component for releasing the engagement between the buckle and the locking block.

[0009] Using the above scheme, the buckles on both sides of the cover can engage with the locking blocks on both sides of the opening end of the fixing frame when the cover moves to the opening end of the fixing frame, thereby limiting the position of the cover. The guide component set near the closing end of the cover allows the buckles on both sides of the cover to automatically deform due to the pressure of the locking blocks during the installation of the cover onto the fixing frame, thus facilitating the locking blocks to engage with the buckles. The unlocking component set away from the closing end of the cover can drive the buckles to release the engagement with the locking blocks when the cover needs to be removed from the fixing frame, thereby allowing the cover to be removed from the fixing frame.

[0010] Preferably, the length of the circuit board is greater than the depth of the slot inside the fixing frame. The cover is provided with a positioning groove that is aligned with the slot when the cover closes the opening of the fixing frame and allows the circuit board to be inserted. After the cover is installed on the fixing frame, the distance between the bottom of the positioning groove and the bottom of the slot is equal to the dimension of the direction in which the circuit board is inserted into the slot. When the cover closes the opening of the fixing frame and the circuit board is inserted into the positioning groove, the latches on both sides of the cover are aligned with the latches on both sides of the fixing frame.

[0011] By adopting the above solution, the length of the circuit board is set to be greater than the depth of the mounting bracket slot. This allows the circuit board to be inserted into the positioning groove on the cover when the cover is installed at the opening of the mounting bracket. At this time, the buckles on both sides of the cover will be aligned with the locking blocks on both sides of the mounting bracket, thus facilitating the interlocking of the buckles and locking blocks when the cover is installed at the opening of the mounting bracket.

[0012] Preferably, the guide component includes a guide slope provided at one end of the buckle near the closing end of the cover.

[0013] With the above solution, the guide slope set near the closing end of the cover can drive the buckle to deform under the pressure of the snap-fit ​​block when the buckle abuts against the snap-fit ​​block, thereby making it easier for the snap-fit ​​block to snap into the buckle and making it more convenient to fix the cover and the fixing frame.

[0014] Preferably, the unlocking component includes a latching plate that is bent away from the cover at one end of the latch away from the closing end of the cover. When the latching plate is latched towards the cover, the end of the latch near the closing end of the cover rotates away from the outer wall cover.

[0015] Using the above solution, the latching plate located at the closing end of the cover can rotate towards the cover, causing the latch to rotate away from the cover. This disengages the latch from the latching block, allowing the latching block and the latch to engage, thus enabling the disassembly of the cover from the fixing frame.

[0016] Preferably, rotation limiting components are provided on both sides of the cover to restrict the buckle plate from rotating towards the cover.

[0017] Preferably, the rotation limiting component includes an abutment plate disposed on the side wall of the cover, one end of which abuts against the inner wall of the snap-action plate near the cover. A mounting groove is recessed on the side wall of the cover. The abutment plate is rotatably disposed in the mounting groove via a rotating shaft. The rotating shaft and the cover are provided with limiting components that restrict the rotation of the rotating shaft and the abutment plate when the abutment plate rotates to the point where one end abuts against the surface of the snap-action plate.

[0018] Using the above solution, the abutment plate, which is rotatably installed in the mounting groove, can abut against the surface of the snap-action plate after rotation. The limiting component can limit the position of the abutment plate when it abuts against the surface of the snap-action plate, keeping the abutment plate in contact with the snap-action plate. This reduces the probability of the buckle disengaging from the snap-action block due to accidental snapping, making the installation between the cover and the fixing frame more stable.

[0019] Preferably, one end of the rotating shaft extends out of the cover body, the width of the mounting groove is greater than the width of the abutment plate, and the abutment plate can move within the mounting groove as the rotating shaft moves horizontally. The limiting component includes a limiting plate provided at one end of the rotating shaft that extends out of the cover body. The cover body is provided with a limiting groove for the limiting plate to be inserted when the abutment plate rotates to abut against the surface of the snap plate and the rotating shaft moves in the direction of penetrating deeper into the mounting groove. The moving distance required for the limiting plate to disengage from the limiting groove is less than or equal to the difference between the width of the mounting groove and the width of the abutment plate.

[0020] Using the above method, when the abutment plate needs to be rotated, the rotating shaft can be pulled outwards from the cover body first, so that the limiting plate on the rotating shaft can be dislodged from the limiting groove on the cover body. At this time, the abutment plate in the mounting groove will move together with the rotating shaft. When the limiting plate is completely dislodged from the limiting groove, the rotating shaft can drive the abutment plate to rotate. When the abutment plate needs to abut against the surface of the snap-on plate, the abutment plate can be rotated to the state of abutting against the surface of the snap-on plate. Then, the rotating shaft is pushed into the cover body, so that the limiting plate on the rotating shaft is inserted into the limiting groove on the cover body to limit the position of the abutment plate, thereby keeping the abutment plate in abutting against the surface of the snap-on plate.

[0021] This utility model, by adopting the above technical solution, has significant technical effects: the slot for inserting the circuit board into the fixing frame allows the circuit board to be stably installed in the fixing frame; the cover can be moved to the opening of the fixing frame after the circuit board is inserted into the slot, and the limiting structure between the opening end of the fixing frame and the cover can limit the position of the cover when it moves to the opening end of the fixing frame and closes the opening end, thereby limiting the circuit board and realizing the installation of the circuit board. Since the installation process of the circuit board only requires inserting the circuit board into the slot of the fixing frame and then moving the cover to the opening end of the fixing frame and limiting the cover by the limiting structure, the installation of the circuit board is faster and more stable.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0033] Example

[0034] A quick-connect structure for a circuit board, reference Figures 1-3 The mounting bracket 1 and the circuit board 2 are installed inside the mounting bracket 1. The mounting bracket 1 includes a fixing bracket 101 with an opening at one end. The fixing bracket 101 has a slot 6 inside that communicates with the opening and allows the circuit board 2 to be inserted. The opening of the fixing bracket 101 is provided with a cover 102 that closes the opening of the fixing bracket 101 when the circuit board 2 is inserted into the slot 6 of the fixing bracket 101. A limiting structure is provided between the two side walls of the opening end of the fixing bracket 101 and the two side walls of the cover 102 to limit the position of the cover 102 when it is installed at the opening of the fixing bracket 101.

[0035] refer to Figure 1 The limiting structure includes locking blocks 4 respectively provided on both sides of the opening end of the fixing frame 101 and buckles 3 provided on both sides of the cover 102, which engage with the locking blocks 4 when the cover 102 closes the opening end of the fixing frame 101. The end of the buckle 3 near the closing end of the cover 102 is provided with an guiding component to facilitate the buckle 3 to deform under the pressure of the locking blocks 4 when the cover 102 is installed to the opening end of the fixing frame 101. The end of the buckle 3 away from the closing end of the cover 102 is provided with an unlocking component for releasing the engagement between the buckle 3 and the locking blocks 4. In this embodiment, there is a gap between the buckle 3 and the side wall of the cover 102 for the buckle 3 to rotate, and in this embodiment, the buckle 3 is made of plastic.

[0036] refer to Figures 2-4 The length of the circuit board 2 is greater than the depth of the slot 6 inside the bracket 101. The cover 102 is provided with a positioning groove 5 that is directly opposite to the slot 6 when the cover 102 closes the opening end of the bracket 101 and allows the circuit board 2 to be inserted. After the cover 102 is installed on the bracket 101, the distance between the bottom of the positioning groove 5 and the bottom of the slot 6 is equal to the dimension of the direction in which the circuit board 2 is inserted into the slot 6. When the cover 102 closes the opening of the bracket 101 and the circuit board 2 is inserted into the positioning groove 5, the buckles 3 on both sides of the cover 102 are directly opposite to the buckles 3 on both sides of the bracket 101.

[0037] refer to Figure 4, Figure 7 The guide component includes a guide slope 7 provided at the end of the buckle 3 near the closing end of the cover 102; the unlocking component includes a snap plate 8 provided at the end of the buckle 3 away from the closing end of the cover 102, which bends away from the cover 102. When the snap plate 8 is snapped in the direction of approaching the cover 102, the end of the buckle 3 near the closing end of the cover 102 rotates away from the outer wall cover 102.

[0038] refer to Figures 5-9 The cover 102 has rotation limiting components on both sides to restrict the rotation of the snap-action plate 8 towards the cover 102. Each rotation limiting component includes an abutment plate 10 on the side wall of the cover 102, one end of which abuts against the inner wall of the snap-action plate 8 near the cover 102. A mounting groove 9 is recessed in the side wall of the cover 102. The abutment plate 10 is rotatably mounted in the mounting groove 9 via a rotating shaft 13. The rotating shaft 13 and the cover 102 are provided with limiting components that restrict the rotation of the rotating shaft 13 and the abutment plate 10 when one end of the abutment plate 10 rotates to abut against the surface of the snap-action plate 8. One end of the shaft 13 extends out of the cover 102. The width of the mounting groove 9 is greater than the width of the abutment plate 10, and the abutment plate 10 can move within the mounting groove 9 as the shaft 13 moves horizontally. The limiting component includes a limiting plate 11 provided at one end of the shaft 13 that extends out of the cover 102. The cover 102 is provided with a limiting groove 12 for the limiting plate 11 to be inserted when the abutment plate 10 rotates to abut against the surface of the snap plate 8 and the shaft 13 moves in the direction of deepening into the mounting groove 9. The distance required for the limiting plate 11 to move out of the limiting groove 12 is less than or equal to the difference between the width of the mounting groove 9 and the width of the abutment plate 10.

[0039] Specific disassembly and assembly process: When circuit board 2 needs to be installed into mounting bracket 1, firstly, insert circuit board 2 into slot 6 on fixing bracket 101. Then, pull the two rotating shafts 13 outwards from the cover 102, so that the limiting plate 11 on the rotating shaft 13 disengages from the limiting groove 12 on the cover 102. When the limiting plate 11 is completely disengaged from the limiting groove 12, the abutment plate 10 can rotate away from the latching plate 8. Then, close the cover 102 to the open end of fixing bracket 101. During the process, the end of the circuit board 2 inserted into the slot 6 that is furthest from the bottom of the slot 6 will first insert into the positioning groove 5 on the cover 102. When the circuit board 2 is inserted into the positioning groove 5, the buckle 3 on the cover 102 and the locking blocks 4 on both sides of the fixing frame 101 will be in a facing state, which facilitates the subsequent locking of the buckle 3 and the locking blocks 4. Then, the cover 102 is moved toward the opening end of the fixing frame 101. At this time, the guide slope 7 set on the buckle 3 will first abut against the locking blocks 4 on both sides of the fixing frame 101. Then, as the cover 102 moves toward the opening end of the fixing frame 101, the guide slope 7 set on the buckle 3 will first abut against the locking blocks 4 on both sides of the fixing frame 101. As 102 continues to move, the locking block 4 will press against the inclined surface 7, causing the buckle 3 to deform. When the locking block 4 is engaged inside the buckle 3, the buckle 3 will return to its original position due to the loss of pressure from the locking block 4. Then, rotate the rotating shaft 13, causing the abutment plate 10 to rotate until it abuts against the latching plate 8. Finally, push the rotating shaft 13 into the cover 102, so that the limiting plate 11 on the rotating shaft 13 is inserted into the limiting groove 12 on the cover 102, thus completing the installation of the circuit board 2. When the circuit board 2 needs to be installed... When removing it from the mounting bracket 1, first, pull the rotating shaft 13 to disengage the limiting plate 11 from the limiting groove 12. Then, rotate the rotating shaft 13 to make the rotating shaft 13 drive the abutment plate 10 to rotate away from the latching plate 8. Then, press the latching plate 8 to make the latching plate 8 drive the buckle 3 to rotate away from the cover 102. At this time, the buckle 3 will gradually disengage from the latching block 4. When the buckle 3 is completely disengaged from the latching block 4, the cover 102 can be removed from the fixing bracket 101. Finally, the circuit board 2 can be removed from the slot 6 to achieve the disassembly of the circuit board 2.
