Description

Technical Field

[0001] This utility model relates to the field of PCB processing technology, and in particular to a PCB anti-misinsertion structure. Background Technology

[0002] A PCB (Printed Circuit Board) is a core component of electronic devices, used for mechanical support and electrical connection of electronic components. It consists of an insulating substrate and conductive copper layers, with circuit traces formed through etching. PCBs are classified by the number of layers into single-sided, double-sided, and multi-layer boards, offering high integration, stability, and mass production capabilities. Design requires consideration of layout, impedance matching, and heat dissipation, while manufacturing involves processes such as photolithography, drilling, and electroplating. Widely used in communications, computers, and consumer electronics, PCBs are a key foundation for the miniaturization and intelligentization of modern electronic products. Their performance directly affects the reliability and lifespan of the equipment.

[0003] Typically, a complex electronic device is composed of multiple PCBs. This requires workers to assemble these different PCBs sequentially. However, in practice, PCBs often look very similar, and workers may accidentally pick the wrong PCB during assembly. This can lead to anything from being unable to assemble the device and damaging the interfaces on the PCB, to more serious issues like the entire electronic product being destroyed due to incorrect assembly.

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] A PCB anti-misinsertion structure includes: a handle 1, a clamping plate 2, and a label 3. The handle 1 conforms to the human hand. The clamping plate 2 is used to hold the PCB board. There are two clamping plates 2. The handle 1 is connected to one of the clamping plates 2. The handle 1 is also connected to the other clamping plate 2 via a transmission connection, so as to move the clamping plates 2 closer together or further apart. The label 3 is connected to one of the clamping plates 2.

[0020] In practical applications, the corresponding operation numbers are pre-marked on label 3. Then, the corresponding PCB boards are clamped using clamping plate 2. For example, if label 3 is number 2, it indicates that this PCB board is the second piece to be assembled. Thus, the numbers on label 3 are clearly visible, allowing workers to simply pick up the PCB boards sequentially according to their numbers during assembly, effectively preventing damage to PCB boards or electronic products due to worker error. It is worth noting that in actual production, to improve efficiency, PCB boards are produced in batches; that is, within the same batch, the PCB board model is the same. Therefore, different PCB board models only need to be placed together during assembly. Therefore, after the same batch of PCB boards is produced, there is no need to distinguish the PCB board models; simply configure the corresponding clamping plate 2 and label 3.

[0021] A transmission structure 11 is provided inside the grip 1. The transmission structure 11 includes a pressure plate 111, a connecting rod 112, and a return spring 113. The pressure plate 111 is slidably connected to the grip 1. One end of the connecting rod 112 is fixedly connected to the pressure plate 111, and the other end is connected to the clamping plate 2. The return spring 113 is disposed inside the grip 1. One end of the return spring 113 abuts against the inner wall of the grip 1, and the other end is connected to the pressure plate 111.

[0022] When it is necessary to remove the PCB board held by clamp 2, the operator grips handle 1 firmly to press down on pressure plate 111, causing it to slide relative to handle 1. At this time, pressure plate 111, through connecting rod 112, drives the corresponding clamp 2 to slide, increasing the distance between the two clamps 2. The operator can then remove the PCB board between the two clamps 2. Simultaneously, as pressure plate 111 slides, it compresses return spring 113, allowing it to accumulate elastic force. After the PCB board is removed, the operator releases handle 1, and pressure plate 111 returns to its initial position under the elastic force of return spring 113, thus causing clamp 2 to return to its initial state. Conversely, the operator can then use clamp 2 to grip the PCB board.

[0023] The clamping plate 2 is also provided with a protective sponge 21. A receiving groove 22 is formed on the clamping plate 2. The protective sponge 21 is embedded in the receiving groove 22. An mounting plate 211 is also provided on the protective sponge 21. The mounting plates 211 are respectively located on both sides of the protective sponge 21. The mounting plates 211 are connected to the protective sponge 21 via Velcro. The mounting plates 211 have protrusions. The mounting plates 211 are embedded in the receiving groove 22 through the protrusions.

[0024] In practice, the surface of a PCB board contains various electronic components of varying heights, creating uneven protrusions. When the clamping plate 2 holds the PCB board, the protective sponge 21 comes into contact with it. As the clamping plate 2 gradually moves closer, the protective sponge 21 deforms under the pressure of the PCB board, preventing damage. Furthermore, the protective sponge 21 acts as a buffer layer, protecting the PCB board during transport and preventing damage from impacts. However, with prolonged use, the protective sponge 21 inevitably wears down. When the protective sponge 21 wears to a certain extent, the mounting plate 211 can be removed from the receiving slot 22, allowing the protective sponge 21 to be removed. A new protective sponge 21 can then be attached to the mounting plate 211 using Velcro, completing the replacement. The mounting plate 211 is made of hard plastic and is used to position the protective sponge 21 within the receiving slot 22. Meanwhile, the mounting plate 211 is located on both sides of the protective foam to prevent the area where the mounting plate 211 is located from directly contacting the PCB board and affecting the protective performance of the PCB board.

[0025] The clamping plate 2 is also provided with an assembly structure 23. The assembly structure 23 includes an assembly rod 231, a positioning protrusion 232, and a positioning spring 233. One end of the assembly rod 231 is fixedly connected to the clamping plate 2. The positioning protrusion 232 is located at the end of the assembly rod 231 away from the clamping plate 2. The positioning protrusion 232 is slidably connected to the assembly rod 231. The positioning spring 233 is located inside the assembly rod 231. One end of the positioning spring 233 is connected to the positioning protrusion 232, and the other end is connected to the assembly rod 231. The positioning protrusion 232 has a triangular cross-section.

[0026] Corresponding to the assembly structure 23, the handle 1 and connecting rod 112 are provided with assembly slots. In actual applications, the size of the PCB board is not the same. The operator needs to select the clamping plate 2. After selection, the operator holds the clamping plate 2 and aligns the assembly structure 23 with the assembly slot. Then, the assembly structure 23 is pushed into the assembly slot. During the pushing process, the outer wall of the assembly slot abuts against the positioning protrusion 232. Because the cross-section of the positioning protrusion 232 is triangular, when the pushing force applied to the assembly structure 23 is large enough, the positioning protrusion 232 will retract into the assembly structure 23 under the action of the inclined surface of the positioning protrusion 232. When the positioning protrusion 232 retracts, it will compress the positioning spring 233, causing the positioning spring 233 to accumulate elastic force. At this time, the operator can continue to push the assembly structure 23 into the assembly slot. When the assembly structure 23 is fully inserted into the assembly slot, the positioning protrusion 232 pops out under the push of the positioning spring 233 because there is a space in the assembly slot that matches the positioning protrusion 232, thus completing the positioning of the clamping plate 2. Conversely, when the clamping plate 2 needs to be replaced, as long as the pulling force applied to the clamping plate 2 is large enough, the assembly structure 23 can be pulled out of the assembly slot. Therefore, this invention can effectively adapt to PCB boards of different sizes.

[0027] The label 3 is also provided with sliding protrusions 31 and actuating protrusions 32. Sliding protrusions 31 are respectively located on both sides of the label 3. The label 3 can slide into the clamping plate 2 via the sliding protrusions 31. The upper surface of the label 3 is flush with the upper surface of the clamping plate 2. The actuating protrusions 32 are fixedly connected to the label 3. The actuating protrusions 32 protrude from the clamping plate 2.

[0028] In practical applications, staff can remove the label 3 from the clamp 2 by moving the protrusion 32, thus completing the replacement of the label 3.
