Abstract
Description
Technical Field
[0001] This utility model relates to a circuit board, specifically a multi-layer enclosed high-shield circuit board, belonging to the field of circuit board technology. Background Technology
[0002] Enclosed circuit boards improve electromagnetic shielding through a multi-layer enclosed structure, reducing the impact of external electromagnetic interference on the circuit. This structure effectively isolates electromagnetic waves, protecting sensitive components on the circuit board from interference, thereby improving the stability and reliability of the equipment.
[0003] However, traditional multi-layer enclosed circuit boards are mostly installed on equipment with multiple screws. Therefore, when the circuit board is damaged and needs to be disassembled for repair, it takes time to turn the screws to remove the circuit board. This is not only time-consuming, but also can easily damage the screw holes on the equipment by frequently turning the screws, making it impossible to install the circuit board. At the same time, screw installation does not have a shock absorption effect. Therefore, when the equipment is impacted and vibrates, the circuit board will also be greatly affected, which can easily damage the circuit board and result in poor safety. Utility Model Content
[0004] The purpose of this invention is to provide a multi-layer enclosed high-shield circuit board to solve the above problems. It enables quick assembly and disassembly of the circuit board, facilitates its inspection and maintenance, and provides shock absorption and protection after installation, thereby improving safety in use.
[0005] This utility model achieves the above-mentioned objective through the following technical solution: a multi-layer enclosed high-shield circuit board includes a circuit board body. Two support plates are provided on one side of the circuit board body. Two positioning sleeves are fixedly connected to the support plates. Four positioning sleeves penetrate the same circuit board body. A shock-absorbing sleeve is provided on the outside of the positioning sleeves. The outer side of the shock-absorbing sleeve abuts against the circuit board body. A pressure plate is provided on one side of the support plates. Two inserts are fixedly connected to the pressure plate. The inserts engage with adjacent positioning sleeves. A fixing structure is provided on the inserts. The fixing structure includes a connecting rod and a slider. A slider is slidably connected to the inserts. The top ends of the two sliders are fixedly connected to the same connecting rod. The slider is provided with four guide grooves. Two locking blocks are slidably connected to the inserts. A guide shaft is fixedly connected to the locking blocks. The two ends of the guide shaft extend into the interior of the two guide grooves and are slidably connected to the sliders. One end of the locking block engages with the positioning sleeve. A first shock-absorbing pad abuts against the support plates and the circuit board body. A second shock-absorbing pad abuts against the pressure plate and the circuit board body.
[0006] Preferably, two positioning posts are fixedly connected to the top of the pressure plate, and springs are sleeved on the outside of the positioning posts. One end of the spring abuts against the connecting rod, and the other end abuts against the pressure plate.
[0007] Preferably, the two guide grooves located on the same side of the slider have a V-shaped structure, and the guide shaft passes through the block.
[0008] Preferably, the vertical cross-section of the card block near the positioning sleeve is triangular, and the two card blocks are symmetrically distributed about the middle of the slider.
[0009] Preferably, the bottom of the vertical section of the insert block has a trapezoidal structure, and the top of the vertical section of the shock-absorbing sleeve has a trapezoidal structure.
[0010] Preferably, the bottom end of the positioning sleeve is provided with a mounting hole, and the center of the mounting hole and the center of the positioning sleeve are on the same straight line.
[0011] Preferably, the pallet is provided with a first placement groove, and a first shock-absorbing pad is engaged inside the first placement groove.
[0012] Preferably, the pressure plate is provided with a second placement groove, and a second shock-absorbing pad is engaged inside the second placement groove.
[0013] Preferably, a connecting piece is fixedly connected to the pressure plate, and the vertical cross-section of the connecting piece is L-shaped.
[0014] The beneficial effects of this utility model are as follows: After the circuit board body is installed, the two first shock-absorbing pads and the two second shock-absorbing pads will abut against the two sides of the circuit board body respectively. At the same time, the shock-absorbing sleeve passes through the through hole on the circuit board body and abuts against the inside of the through hole on the circuit board body. Therefore, when the equipment is impacted and vibrates, the first shock-absorbing pads, the second shock-absorbing pads and the shock-absorbing sleeve can play a shock-absorbing and protective role for the circuit board body, avoiding damage to the circuit board body due to large vibrations, thereby effectively improving the safety of use. When the circuit board body is damaged and needs to be disassembled for maintenance, the connecting rod can be pressed. The movement of the connecting rod will drive the two sliders to move. The movement of the sliders will drive the four guide grooves to move. At the same time, the movement of the sliders will abut against the two guide shafts moving inside the guide grooves. The movement of the guide shafts will drive the locking block to move away from the positioning sleeve. When the locking block and the positioning sleeve are not engaged, the pressure plate can be removed from one side of the circuit board body, and then the circuit board body can be moved to disengage from the positioning sleeve, thereby realizing the quick disassembly of the circuit board body, shortening the disassembly time, and facilitating the maintenance of the circuit board body.

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a multi-layer enclosed high-shield circuit board includes a circuit board body 1. Two support plates 2 are provided on one side of the circuit board body 1. Two positioning sleeves 3 are fixedly connected to the support plates 2. Four positioning sleeves 3 penetrate the same circuit board body 1. Shock-absorbing sleeves 4 are fitted around the outside of the positioning sleeves 3, and the outer side of the shock-absorbing sleeves 4 abuts against the circuit board body 1. A pressure plate 5 is provided on one side of the support plates 2. Two inserts 6 are fixedly connected to the pressure plate 5. The inserts 6 engage with adjacent positioning sleeves 3. A fixing structure 7 is provided on the inserts 6, which includes a connecting rod 701 and a slider 702. The sliding connection includes a slider 702, and the top ends of the two sliders 702 are fixedly connected to the same connecting rod 701. The slider 702 is provided with four guide grooves 703. The insert block 6 is slidably connected to two locking blocks 705. The locking blocks 705 are fixedly connected to a guide shaft 704. The two ends of the guide shaft 704 extend into the interior of the two guide grooves 703 and are slidably connected to the sliders 702. One end of the locking block 705 is engaged with the positioning sleeve 3. The support plate 2 and the circuit board body 1 are in contact with a first shock-absorbing pad 10, and the pressure plate 5 and the circuit board body 1 are in contact with a second shock-absorbing pad 12.
[0023] As a technical optimization solution of this utility model, such as Figure 3 As shown, two positioning posts 706 are fixedly connected to the top of the pressure plate 5. The positioning posts 706 can limit the spring 707 to prevent the spring 707 from detaching from the connecting rod 701 and the pressure plate 5. The spring 707 can automatically engage the locking block 705 with the positioning sleeve 3 after the insert block 6 moves to the designated position, thereby improving the convenience of installation operation.
[0024] As a technical optimization solution of this utility model, such as Figure 4 As shown, the two guide grooves 703 located on the same side of the slider 702 form a V-shaped structure. Therefore, when the slider 702 moves in one direction, the two locking blocks 705 can move in opposite directions, which makes it easy for the two locking blocks 705 to not engage with the positioning sleeve 3 at the same time.
[0025] As a technical optimization solution of this utility model, such as Figure 3 As shown, the vertical cross-section of the locking block 705 near the positioning sleeve 3 is triangular, so that when the insert block 6 moves toward the positioning sleeve 3, the positioning sleeve 3 can automatically abut against the locking block 705.
[0026] As a technical optimization solution of this utility model, such as Figure 3 As shown, the bottom of the vertical section of the insert 6 is trapezoidal, which can guide the movement of the insert 6 and the positioning sleeve 3 during engagement. The top of the vertical section of the shock-absorbing sleeve 4 is trapezoidal, which can guide the movement of the shock-absorbing sleeve 4 as it passes through the circuit board body 1.
[0027] As a technical optimization solution of this utility model, such as Figure 3 As shown, the bottom end of the positioning sleeve 3 is provided with a mounting hole 13, so the tray 2 can be installed on the equipment through the mounting hole 13 and screws.
[0028] As a technical optimization solution of this utility model, such as Figure 5 As shown, the tray 2 is provided with a first placement groove 9, so the first shock-absorbing pad 10 can be placed inside the first placement groove 9, thereby achieving the positioning of the first shock-absorbing pad 10.
[0029] As a technical optimization solution of this utility model, such as Figure 5 As shown, the pressure plate 5 is provided with a second placement groove 11, so that the second shock-absorbing pad 12 can be placed inside the second placement groove 11, thereby realizing the positioning of the second shock-absorbing pad 12.
[0030] As a technical optimization solution of this utility model, such as Figure 1 and Figure 2 As shown, a connecting piece 8 is fixedly connected to the pressure plate 5. Since the vertical cross-section of the connecting piece 8 is L-shaped, the fingers can grip the connecting piece 8 when the pressure plate 5 is removed, thus facilitating the movement of the pressure plate 5.
[0031] In use, this utility model allows the support plate 2 to be installed on the equipment via screws and mounting holes 13. Then, the circuit board body 1 is moved to engage with the four shock-absorbing sleeves 4, thus positioning the circuit board body 1. Next, the pressure plate 5 is moved to engage the two inserts 6 with the two positioning sleeves 3 simultaneously. When the second shock-absorbing pad 12 contacts the circuit board body 1, the locking block 705 automatically engages with the positioning sleeves 3 under the action of the spring 707. At this point, the circuit board body 1 cannot move, thus achieving installation. After the circuit board body 1 is installed, the two first shock-absorbing pads 10 and the two second shock-absorbing pads 12 will contact the two sides of the circuit board body 1 respectively. Simultaneously, the shock-absorbing sleeves 4 pass through the through holes on the circuit board body 1 and contact the inside of the through holes. Therefore, when the equipment is impacted and vibrates, the vibration can be absorbed by the first shock-absorbing pads 10... The second shock-absorbing pad 12 and the shock-absorbing sleeve 4 provide shock absorption and protection for the circuit board body 1, preventing it from being damaged by excessive vibration, thus effectively improving the safety of use. When the circuit board body 1 is damaged and needs to be disassembled for repair, the connecting rod 701 can be pressed. The movement of the connecting rod 701 will drive the two sliders 702 to move. The movement of the sliders 702 will drive the four guide grooves 703 to move. At the same time, the movement of the sliders 702 will abut against the two guide shafts 704, which will move inside the guide grooves 703. The movement of the guide shafts 704 will drive the locking block 705 to move away from the positioning sleeve 3. When the locking block 705 and the positioning sleeve 3 are not engaged, the pressure plate 5 can be removed from one side of the circuit board body 1. Then, the circuit board body 1 can be moved to disengage from the positioning sleeve 3, thereby achieving quick disassembly of the circuit board body 1, shortening the disassembly time, and facilitating the inspection and maintenance of the circuit board body 1.
