Description
Technical Field
[0001] This utility model relates to the field of circuit board technology, and in particular to an anti-static PCBA motherboard. Background Technology
[0002] The PCBA motherboard is the core component of electronic devices. It solders electronic components onto a printed circuit board (PCB) using surface mount technology (SMT) or through-hole technology to form a circuit system with specific functions.
[0003] PCBA motherboards require electrostatic discharge protection primarily because electrostatic discharge (ESD) can cause irreversible physical damage or functional failure. Especially with the high integration and miniaturization of electronic components today, ESD protection has become a key aspect of ensuring motherboard reliability.
[0004] Existing PCBA motherboards generally have difficulty preventing static electricity, which can cause irreversible damage to the PCBA motherboard when excessive static electricity accumulates during use. Therefore, an anti-static PCBA motherboard is proposed to address the above problem. Utility Model Content
[0005] The purpose of this invention is to provide an anti-static PCBA motherboard to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: including a fixing base, on which two sets of connecting posts are fixedly connected, a fixing groove is fixedly connected to one set of connecting posts, a circuit board body is disposed between the pair of fixing grooves, conductive strips are disposed on the fixing grooves, the conductive strips are arranged in an array, and fixing components are disposed on the fixing grooves.
[0007] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly involves: by fixing a connecting post to the fixed base, fixing a fixing groove to the connecting post, and fixing multiple conductive strips to the fixing groove, the static electricity generated on the circuit board body during use can be conducted to the connecting post through multiple conductive strips, and then conducted to the fixed base by the connecting post for dispersion, thereby reducing the damage to the circuit board body caused by excessive static electricity generated on the circuit board body during use that is not discharged. A pressing block is fixed to the end of the connecting rod, and a spring is fixed between the pressing block and the fixing groove. It can quickly fix the circuit board body during use, making it convenient to quickly install and remove the circuit board body during use; By rotating and connecting rollers to the pressing block, the rollers can contact and rotate with the circuit board body during use, which can reduce the scratches on the surface of the circuit board body caused by excessive friction when the pressing block directly contacts the circuit board body during use. By fixing multiple rubber rings on the roller, the friction between the roller and the circuit board body can be increased during use, reducing the wobbling of the circuit board body due to low friction when the roller presses and fixes the circuit board body during use. By fixing a rubber block to the fixing groove, the circuit board body can come into contact with the rubber block during use, which can reduce the direct contact between the edge of the circuit board body and the fixing groove during use, thus reducing the possibility of scratches on the circuit board body. By fixing multiple conductive posts to the mounting base, static electricity on the circuit board can be guided during use, reducing the possibility of static electricity buildup on the circuit board and causing damage. To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0010] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.
[0011] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.
[0012] Please refer to Figure 1 to Figure 4 This utility model provides an anti-static PCBA motherboard, including a mounting base 1. Two sets of connecting posts 11 are fixedly connected to the mounting base 1. A fixing groove 12 is fixedly connected to one set of connecting posts 11. A circuit board body 13 is disposed between a pair of fixing grooves 12. Conductive strips 14 are disposed on the fixing grooves 12, and the conductive strips 14 are arranged in an array. A fixing component 15 is disposed on the fixing grooves 12. When needed, the circuit board body 13 is placed between the pair of fixing grooves 12, and then fixed using the fixing component 15. After fixing, the mounting base 1 and the circuit board body 13 are placed together in a designated position, and the mounting base 1 is fixed. When static electricity is generated on the surface of the circuit board body 13 during use, the static electricity is conducted through the fixing grooves 12 to the multiple conductive strips 14, and then conducted to the connecting posts 11. When the static electricity is conducted to the connecting posts 11, the connecting posts 11 disperse the static electricity to the mounting base 1. The static electricity is then dispersed onto the chassis for elimination. By fixing a connecting post 11 to the mounting base 1, fixing a mounting groove 12 to the connecting post 11, and fixing multiple conductive strips 14 to the mounting groove 12, the static electricity generated on the circuit board body 13 during use can be conducted to the connecting post 11 through the multiple conductive strips 14, and then conducted to the mounting base 1 by the connecting post 11 for dispersion. This reduces the possibility of damage to the circuit board body 13 caused by excessive static electricity generated on the circuit board body 13 during use that is not discharged.
[0013] Please refer to Figure 1 to Figure 4 The fixing component 15 includes a connecting rod 2, which is through-hole and slidably fitted with the fixing groove 12. A pressing block 21 is fixedly connected to the end of the connecting rod 2. A spring 22 is fixed between the pressing block 21 and the fixing groove 12. When the circuit board body 13 is placed in the fixing groove 12, the circuit board body 13 pushes the multiple pressing blocks 21 upward. At this time, the spring 22 is compressed. When the spring 22 is compressed, the connecting rod 2 moves upward. At this time, the circuit board body 13 smoothly enters between the pressing block 21 and the conductive strip 14. After the circuit board body 13 is placed, the pressing block 21 is pushed towards the circuit board body 13 under the elastic force of the spring 22. At this time, the pressing block 21 presses and fixes the circuit board body 13. By fixing the pressing block 21 at the end of the connecting rod 2 and fixing the spring 22 between the pressing block 21 and the fixing groove 12, the circuit board body 13 can be quickly fixed during use, which facilitates the quick installation and disassembly of the circuit board body 13 during use.
[0014] Please refer to Figure 1 to Figure 4 A roller 3 is rotatably connected to the pressing block 21. The roller 3 is located between the pressing block 21 and the conductive strip 14. When the circuit board body 13 is placed in the fixing groove 12, the circuit board body 13 and the roller 3 are in contact. When the circuit board body 13 moves to the other end of the fixing groove 12, the roller 3 rotates. By rotatably connecting the roller 3 to the pressing block 21, the roller 3 can contact and rotate with the circuit board body 13 during use. This can reduce the possibility of scratches on the surface of the circuit board body 13 due to excessive friction when the pressing block 21 directly contacts the circuit board body 13 during use.
[0015] Please refer to Figure 1 to Figure 4 Multiple rubber rings 4 are fixedly attached to the roller 3. The rubber rings 4 are arranged in an array. When the roller 3 presses the circuit board body 13, the rubber rings 4 come into contact with the circuit board body 13. When the rubber rings 4 come into contact with the circuit board body 13, the friction between the roller 3 and the circuit board body 13 is increased. By fixing multiple rubber rings 4 on the roller 3, the friction between the roller 3 and the circuit board body 13 can be increased during use, reducing the possibility of the circuit board body 13 shaking due to low friction when the roller 3 presses and fixes the circuit board body 13 during use.
[0016] Please refer to Figure 1 to Figure 4A rubber block 5 is fixedly attached to the fixing groove 12. When the circuit board body 13 is placed inside the fixing groove 12, the circuit board body 13 and the rubber block 5 fixedly attached to the fixing groove 12 come into contact. When the circuit board body 13 and the rubber block 5 are in contact, the rubber block 5 separates the circuit board body 13 from the fixing groove 12. By fixing the rubber block 5 to the fixing groove 12, the circuit board can be kept in place during use. The contact between the circuit board body 13 and the rubber block 5 can reduce the direct contact between the edge of the circuit board body 13 and the fixing groove 12 during use, thus reducing the possibility of scratches on the circuit board body 13.
[0017] Please refer to Figure 1 to Figure 4 The mounting base 1 has multiple conductive posts 6 fixedly attached to it. The conductive posts 6 are arranged in an array. When the circuit board body 13 is placed between a pair of fixing slots 12, the circuit board body 13 is in contact with the multiple conductive posts 6. When static electricity is generated on the circuit board body 13, the static electricity is conducted to the multiple conductive posts 6. When the static electricity is conducted to the multiple conductive posts 6, the multiple conductive posts 6 disperse the static electricity and conduct it to the mounting base 1. Subsequently, the mounting base 1 disperses the static electricity. By fixing multiple conductive posts 6 to the mounting base 1, the static electricity on the circuit board body 13 can be guided during use, reducing the possibility of static electricity accumulating on the circuit board body 13 and causing damage to the circuit board body 13 during use.
[0018] Working principle: When needed, the circuit board body 13 is placed between a pair of fixing slots 12, and then the fixing component 15 is used to fix the circuit board body 13. After fixing, the fixing base 1 and the circuit board body 13 are placed together in the designated position and the fixing base 1 is fixed. When static electricity is generated on the surface of the circuit board body 13 during use, the static electricity is conducted through the fixing slots 12 to multiple conductive strips 14, and then to the connecting post 11. When the static electricity is conducted to the connecting post 11, the connecting post 11 disperses the static electricity to the fixing base 1 and then to the chassis for elimination. When the circuit board body 13 is placed in the fixing slot 12, the circuit board body 13 pushes multiple pressing blocks 21 upward. At this time, the spring 22 is compressed. When the spring 22 is compressed, the connecting rod 2 moves upward. At this time, the circuit board body 13 smoothly enters between the pressing blocks 21 and the conductive strips 14. After the circuit board body 13 is placed, the pressing blocks 21 are pushed upward by the elastic force of the spring 22. Pushing towards the circuit board body 13, the pressing block 21 presses and fixes the circuit board body 13. When the circuit board body 13 is placed in the fixing groove 12, the circuit board body 13 and the roller 3 are in contact. When the circuit board body 13 moves to the other end of the fixing groove 12, the roller 3 rotates. When the roller 3 presses the circuit board body 13, the rubber ring 4 is in contact with the circuit board body 13. When the rubber ring 4 is in contact with the circuit board body 13, the friction between the roller 3 and the circuit board body 13 increases. When the circuit board body 13 is placed inside the fixing groove 12, the circuit board body 13 and the fixing groove 12 are fixed. When the circuit board body 13 and the rubber block 5 are in contact, the rubber block 5 separates the circuit board body 13 from the fixing groove 12. When the circuit board body 13 is placed between a pair of fixing grooves 12, the circuit board body 13 is in contact with multiple conductive posts 6. When static electricity is generated on the circuit board body 13, the static electricity is conducted to the multiple conductive posts 6. When the static electricity is conducted to the multiple conductive posts 6, the multiple conductive posts 6 disperse the static electricity and conduct it to the fixing seat 1. Then the fixing seat 1 disperses the static electricity. By fixing multiple conductive posts 6 on the fixing seat 1, the static electricity on the circuit board body 13 can be guided during use, reducing the situation where static electricity accumulates on the circuit board body 13 during use and causes damage to the circuit board body 13.
