Description

Technical Field

[0001] The present application relates to the technical field of circuit boards, and more specifically, to a circuit board for preventing a gold finger PIN position from shifting. Background Art

[0002] Circuit boards are important components for manufacturing or producing electronic products. If you want to connect two circuit boards to each other (i.e. physically connect the two circuit boards together in the circuit), you will generally use edge connectors commonly known as "gold fingers". The gold fingers contain many exposed copper pads. When using them, insert one of the gold fingers into the appropriate slot of the other circuit board.

[0003] The existing gold fingers of circuit boards are usually an integral section. However, there are some problems when processing the gold fingers on the circuit boards. The size of the circuit board has expansion and contraction changes, which are caused by the expansion and contraction of the circuit board substrate after etching and the secondary thermal expansion of the material caused by the hot pressing of the product gold fingers and the screen gold fingers. Due to the change in the size of the flexible circuit board, it is easy to cause the product gold fingers and the screen gold fingers to shift when they are aligned. Utility Model Content

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0023] Reference Figure 1-Figure 4, a circuit board for preventing the position shift of a gold finger PIN, comprising a PCB board body 2, a PCB board body top 3 integrally connected to the PCB board body 2, an outer wall of the PCB board body top 3 is provided with evenly distributed card slots, a gold finger 6 is arranged in the card slot, one end of the gold finger 6 is connected to a circuit 7, and the other end of the circuit 7 is connected to a conductive member 8; the gold finger 6 is designed in the card slot, and this structure can effectively prevent the gold finger 6 from being displaced or offset during the plug-in or vibration process, thereby ensuring the connection stability of the PCB board with other devices or modules, and the gold finger 6 is restricted in the card slot, which can reduce the heat accumulation caused by poor contact, the stable connection between the gold finger 6 and the circuit 7, ensures the integrity and quality of signal transmission, reduces the signal attenuation or distortion caused by poor contact, and solves the existing PCB board design, the gold finger 6 is often directly exposed on the board surface, and is prone to shift or damage. The present design uses a card slot to fix the gold finger 6, which effectively solves this problem. The PCB board structure with a card slot design not only improves the connection stability and signal transmission quality, but also optimizes the heat dissipation performance, simplifies the assembly process, enhances the reliability and durability of the equipment, and effectively solves the problems existing in the traditional PCB board design.

[0024] Through the above technical solution, a PCB board green oil layer 1 is arranged outside the PCB board body 2 and the top end 3 of the PCB board body.

[0025] Through the above technical solution, the top end 3 of the PCB body away from the green oil layer 1 of the PCB is provided with an inclined surface with an angle of 20-60°; the primary function of the green oil layer 1 is to provide insulation protection. On the circuit board, various circuits and components need to maintain a certain degree of electrical isolation to prevent short circuits and electrical failures. The green oil layer can cover the exposed copper circuits and solder joints to form an insulating layer to effectively prevent electrical contact and short circuits.

[0026] Through the above technical scheme, a positioning groove is provided on the outer wall of the inclined surface of the top 3 of the PCB board body, the positioning groove corresponds to the position of the card slot, and the positioning groove is arranged along the inclined surface of the top 3 of the PCB board body, and a gold finger reinforcement piece 5 is arranged in the positioning groove, and one end of the gold finger reinforcement piece 5 is fixedly connected with one end of the gold finger 6; the positioning groove is used to fix the gold finger reinforcement piece 5, and the gold finger reinforcement piece 5 can fix one end of the gold finger 6 to prevent the gold finger 6 from tilting during use, increase the fixing effect of the gold finger 6, and prevent the gold finger 6 from being skewed. At the same time, the gold finger 6 is connected to the gold finger reinforcement piece 5 together. During the processing, the positioning groove corresponds to the position of the card slot, and the gold finger 6 is connected to the gold finger reinforcement piece 5 through electroplating. The fixing strength of the gold finger 6 is increased by the gold finger reinforcement piece 5 to prevent the gold finger 6 from being skewed during the processing. At the same time, the inclined surface of the top 3 of the PCB board body enables the gold finger 6 to be more accurately positioned when inserted into the card slot, avoiding poor contact or damage caused by position offset.

[0027] Through the above technical solution, the outer wall of the gold finger 6 is provided with a rectangular convex strip, which is symmetrically arranged on both sides of the gold finger 6, and the internal shape of the card slot is consistent with the external shape of the convex strips on both sides of the gold finger 6. The design of the convex strip can enhance the connection stability, increase the contact area between the gold finger and the card slot, thereby enhancing the stability of the connection and reducing the risk of accidental disconnection due to vibration or other external forces, while preventing the gold finger 6 from being misplaced. Since the shape of the convex strip and the card slot is consistent, it can ensure that the gold finger is correctly inserted into the card slot, reducing the risk of misplacement and improving durability: the presence of the convex strip can provide additional mechanical strength for the gold finger and reduce damage caused by frequent plugging and unplugging or improper operation.

[0028] Through the above technical solution, such as Figure 4 As shown, the outer wall of the gold finger 6 is provided with a triangular prism-shaped convex strip, which is symmetrically arranged on both sides of the gold finger 6. Due to its special shape, the triangular prism-shaped convex strip has a tighter contact area and fit with the card slot, thereby enhancing the stability of the connection.

[0029] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
