Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and more specifically, to a PCB board structure that is easy to install in a socket. Background Technology

[0002] In the electronic device manufacturing process, the production and testing of PCBs (Printed Circuit Boards) are crucial steps. After production, PCBs need to be installed on specific sockets for comprehensive testing to ensure that their electrical performance, signal transmission, and other indicators meet standards. Only PCBs that pass the test can proceed to the next production stage and become a component of qualified electronic devices.

[0003] Currently, the industry standard for determining the correct mounting orientation of PCBs on sockets is to simply affix mounting markings to the PCB or socket itself. These markings are typically presented as simple graphics, symbols, or special markings, designed to provide directional guidance for operators. However, in practice, relying solely on these markings is still insufficient to prevent misalignment. Because PCB and socket installation is frequent and demanding, operators are prone to visual fatigue and distraction after prolonged repetitive work. Furthermore, some mounting markings may not be conspicuous or clear enough, making them difficult to accurately identify in complex production environments. This results in misalignment occurring frequently even with markings, severely impacting production efficiency and product quality.

[0004] The above shortcomings need to be improved. Summary of the Invention

[0005] To solve or alleviate the problem of misalignment during PCB and socket installation, this utility model provides a PCB board structure that facilitates installation in a socket.

[0006] The technical solution of this utility model is as follows:

[0007] A PCB board structure for easy installation in a socket includes multiple stacked circuit board bodies. Each circuit board body includes a first circuit board that directly contacts the multiple sockets and a second circuit board that does not directly contact the sockets. A foolproof part is provided at a corresponding position on each circuit board body. The foolproof part is used for positioning each circuit board body and positioning each circuit board body with the socket.

[0008] Furthermore, the foolproof part includes a foolproof chamfer, and one corner of each of the circuit board bodies is provided with a foolproof chamfer.

[0009] Furthermore, the error prevention part includes a connecting pad, and a connecting pad is provided between adjacent circuit board bodies. At least one connecting pad is provided at each of the four corners of the circuit board body, wherein the size of the connecting pad at one corner is different from the size of the connecting pads at the other three corners.

[0010] Furthermore, the connecting pads are rectangular or circular.

[0011] Furthermore, the edges of each of the circuit board bodies are similar in shape, and the size of the second circuit board is no larger than the size of the first circuit board.

[0012] Furthermore, the first circuit board has a first connecting protrusion on its edge, and the second circuit board has a second connecting protrusion on its edge at a position corresponding to the first connecting protrusion.

[0013] Furthermore, each of the three triangles of each circuit board body is provided with a positioning mark.

[0014] Furthermore, the bottom of the first circuit board is provided with contact pads, which are rectangular or circular.

[0015] Furthermore, the second circuit board is provided with a pair of material handling openings.

[0016] Furthermore, the diameter of the material intake opening is 1mm to 1.5mm.

[0017] According to the above-described solution, the beneficial effects of this utility model are as follows: By incorporating a mistake-proof feature, on the one hand, during the positioning of the circuit board body and the socket, the mistake-proof feature effectively avoids misalignment caused by unclear installation markings or operator errors, improving installation accuracy and efficiency, and reducing product damage and rework costs due to installation errors. On the other hand, during the positioning of each circuit board body, the mistake-proof feature ensures precise stacking between multiple circuit boards, ensuring the stability of electrical connections and the accuracy of signal transmission, thereby improving the overall performance and reliability of the PCB board and providing a solid guarantee for the stable operation of electronic equipment.

[0025] like Figure 1 and Figure 2 As shown in one embodiment of the present invention, a PCB board structure that is convenient to install in a SOCKET includes multiple stacked circuit board bodies. Each circuit board body includes a first circuit board 1 that is in direct contact with multiple SOCKETs and a second circuit board 2 that is not in direct contact with the SOCKETs. A foolproof part 3 is provided at a corresponding position on the circuit board body. The foolproof part 3 is used for positioning each circuit board body and positioning each circuit board body with the SOCKET.

[0026] During PCB board structure testing, the second circuit board 2 is first aligned with the foolproof features 3 of the first circuit board 1. The circuit board bodies are then stacked and soldered to ensure accurate positioning between them, completing the assembly of the entire PCB board. Next, the PCB board is placed in the socket. Because the circuit board body has foolproof features 3, these features cooperate with the corresponding positioning structure on the socket. During installation, the operator can quickly and accurately find the correct installation direction based on the unique shape and position of the foolproof features 3, smoothly inserting the PCB board into the socket.

[0027] This PCB structure incorporates a foolproof feature 3. Firstly, during the positioning of the PCB body and socket, the foolproof feature 3 effectively prevents misalignment caused by unclear installation markings or operator error, improving installation accuracy and efficiency, and reducing product damage and rework costs due to installation errors. Secondly, during the positioning of each PCB body, the foolproof feature 3 ensures precise stacking between multiple PCBs, guaranteeing the stability of electrical connections and the accuracy of signal transmission. This, in turn, enhances the overall performance and reliability of the PCB, providing a solid guarantee for the stable operation of electronic equipment.

[0028] like Figure 2 As shown, in a preferred embodiment, the foolproof part 3 includes a foolproof chamfer 301, and each circuit board body has a foolproof chamfer 301 at one corner. The foolproof chamfer 301 is 45°.

[0029] In the PCB structure, a 45° anti-foolproof chamfer 301 is set at one corner of each circuit board body, providing a precise reference for the positioning of the circuit board and the socket, as well as among the circuit boards themselves. When the PCB structure is mated with the socket, the 45° anti-foolproof chamfer 301 matches the corresponding 45° chamfer positioning structure on the socket, forming a positioning that allows operators to instantly identify the correct installation direction, preventing installation failures due to incorrect orientation and improving installation accuracy. Secondly, compared to other complex foolproof designs, the 45° anti-foolproof chamfer 301 has a simple manufacturing process, requiring no additional complex molds or high-precision processing equipment, thus reducing production costs. Simultaneously, by reducing product loss and rework costs caused by installation errors, it further saves resources for enterprises and improves economic efficiency. Furthermore, the precise positioning achieved through the anti-foolproof chamfer 301 ensures tight fit and accurate connection between multi-layer circuit boards, ensuring the stability of electrical connections, reducing interference and loss during signal transmission, thereby guaranteeing the overall performance of the PCB board.

[0030] In practical applications, the foolproof chamfer 301 can be other angles, such as 60°, or other shapes, such as rounded corners.

[0031] like Figure 2 and Figure 3 As shown, in a preferred embodiment, the foolproof part 3 includes a connecting pad 302. A connecting pad 302 is provided between adjacent circuit board bodies. At least one connecting pad 302 is provided at each of the four corners of the circuit board body. The size of one corner connecting pad 302 is different from the size of the other triangular connecting pads 302.

[0032] The connection pad 302 is rectangular or circular.

[0033] Connecting pads 302 are provided at the four corners of the circuit board body, with one corner connecting pad 302 having a different size than the others, providing a clear positioning mark 102 for circuit board installation. When connecting multi-layer circuit boards, operators or automated production equipment can quickly compare the size of the connecting pad 302 to determine the correct installation direction, effectively avoiding installation errors caused by incorrect orientation, improving assembly accuracy, and reducing time waste and material loss caused by installation errors. Secondly, the connecting pads 302 between adjacent circuit board bodies form a stable physical connection after soldering, enhancing the bonding strength between multi-layer circuit boards. Whether it is slight vibration in daily use or bumps and impacts that may be encountered during transportation, it can effectively prevent loosening or displacement between circuit boards, ensuring that the entire PCB structure remains stable in various environments and extending the service life of electronic devices. In addition, the uniformly set connecting pads 302 at the four corners facilitate automated soldering operations in the production process, improving production efficiency. Meanwhile, during later maintenance and repair, the connection pad 302 can serve as a clear positioning point, making it convenient for technicians to quickly troubleshoot circuit faults and carry out targeted repairs and replacements, thus reducing maintenance costs and difficulties.

[0034] like Figure 2 As shown, in a preferred embodiment, the edges of each circuit board body are similar in shape, and the size of the second circuit board 2 is not larger than the size of the first circuit board 1.

[0035] The first circuit board 1 has a first connecting protrusion 101 on its edge, and the second circuit board 2 has a second connecting protrusion 201 on its edge at a position corresponding to the first connecting protrusion 101.

[0036] The first connecting protrusion 101 on the first circuit board 1 and the corresponding second connecting protrusion 201 on the second circuit board 2 form a positioning structure. During assembly, operators can quickly and accurately determine the correct installation direction by aligning the two connecting protrusions, effectively avoiding installation errors caused by similar circuit board appearances, improving assembly accuracy, and reducing rework costs and time losses due to incorrect orientation. Furthermore, the connecting protrusions are naturally formed surplus material during circuit board production, requiring no additional processing and saving costs. Using the first circuit board 1 as a dimensional reference, the size of the second circuit board 2 does not exceed that of the first circuit board 1, and their edge shapes are similar, allowing for neat overlap. This PCB structure can adapt to various application scenarios and equipment requirements.

[0037] like Figure 2 As shown, in a preferred embodiment, each of the triangles on each circuit board body is provided with a positioning mark 102.

[0038] The placement of positioning markers 102 at the three corners, using an asymmetrical distribution, is an effective mistake-proofing design. Because the edges of the circuit boards have similar shapes, a symmetrical distribution of the positioning markers 102 could easily lead to orientation confusion during installation. This asymmetrical arrangement prevents the positioning markers 102 from being correctly identified when the circuit board is installed in the wrong orientation, making it easier for operators or automated equipment to detect errors, preventing further erroneous operations, improving the mistake-proofing effect, and ensuring the accuracy and stability of production.

[0039] like Figure 1 As shown, in a preferred embodiment, the bottom of the first circuit board 1 is provided with a contact pad 103, which is rectangular or circular.

[0040] The contact pads 103 at the bottom of the first circuit board 1, whether rectangular or circular, possess excellent conductivity. When the first circuit board 1 is connected to the socket, the contact pads 103 serve as electrical connection points, ensuring stable transmission of current and signals. Rectangular pads, due to their larger contact area, have advantages in carrying high currents, effectively reducing resistance and signal transmission losses, ensuring high-performance operation of electronic equipment. Circular pads can increase pin spacing, save space, facilitate vias between pins, and reduce the risk of short circuits during high-temperature and high-humidity testing. Furthermore, the regular shape of the rectangular or circular contact pads 103 facilitates manufacturing during circuit board production. Whether using traditional printed circuit board manufacturing processes or advanced laser processing technology, contact pads 103 meeting requirements can be precisely manufactured, reducing process difficulty and costs, improving product yield, and facilitating large-scale production.

[0041] like Figure 2As shown, in a preferred embodiment, a pair of material handling openings 202 are provided on the second circuit board 2.

[0042] The diameter of the material feeding opening 202 is 1mm to 1.5mm.

[0043] On the production line, robotic arms or operators can insert the tips of tweezers into the opening to precisely grip the circuit board, avoiding damage caused by directly gripping the edges and ensuring the integrity of the circuit board during handling. The tweezer-compatible gripping opening 202 facilitates finding the gripping position, making the gripping action smoother and more efficient. It allows for quick completion of gripping and initiation of the next operation. In large-scale production, this significantly reduces the processing time for a single circuit board, improving overall production efficiency. The gripping opening 202 is reasonably sized, ensuring the stability of the tweezers' grip while preventing excessive size from affecting the structural stability of the circuit board.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
