Detailed Implementation

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 As shown, an embodiment of this application discloses a circuit board structure inside a POS machine, including a first circuit board 1 and a second circuit board 2. The first circuit board 1 is provided with a first interface 3, and the second circuit board 2 is provided with a second interface 18. It also includes a first injection molding plate 4 injection molded with the first circuit board 1 and a second injection molding plate 5 injection molded with the second circuit board 2. A connecting circuit board 6 is provided on one side of the first circuit board 1 and the second circuit board 2. The connecting circuit board 6 is connected to the first circuit board 1 and the second circuit board 2 respectively, so that the first circuit board 1 and the second circuit board 2 are connected by signals. The first circuit board 1 and the second circuit board 2 form an angle. The first injection molding plate 4 and the second injection molding plate 5 are located on opposite sides of the first circuit board 1 and the second circuit board 2.

[0024] Specifically, in the above structure, the first circuit board 1, the second circuit board 2, and the connecting circuit board 6 can be FPC flexible circuit boards, which have good flexibility and plasticity, and can be bent and folded according to actual needs to adapt to different installation spaces and connection requirements. The connecting circuit board 6, as a bridge between the first circuit board 1 and the second circuit board 2, not only realizes the effective transmission of signals, but also enhances the stability and reliability of the entire circuit board structure through its design.

[0025] Meanwhile, the included angle between the first circuit board 1 and the second circuit board 2 can be adjusted according to actual needs, ranging from 0 to 90 degrees. This design makes the circuit board structure more flexible and adaptable to different installation spaces and connection requirements. It effectively reduces the space occupied by the circuit board within the POS machine, improves space utilization, and reduces the POS space occupancy rate for customers.

[0026] In this embodiment, the first circuit board 1, the second circuit board 2, and the connecting circuit board 6 are integrally formed.

[0027] Specifically, the aforementioned one-piece molding design not only enhances the stability and reliability of the circuit board structure but also further simplifies the production process. Compared to traditional split circuit boards, the one-piece molding structure eliminates the need for multiple assembly and connection steps during production, thereby reducing production steps and costs. Simultaneously, the one-piece molding design also helps improve the precision and consistency of the circuit board structure, ensuring product quality.

[0028] In this embodiment, the first injection molding plate 4 is provided with a first threaded hole 71, the second injection molding plate 5 is provided with a second threaded hole 72, and a connecting screw extending into the first threaded hole 71 and the second threaded hole 72 is also included.

[0029] Specifically, the design of the connecting screws allows the first injection molding plate 4 and the second injection molding plate 5 to be firmly connected together, enhancing the stability and reliability of the entire circuit board structure. At the same time, the connecting screws are relatively easy to remove and install, facilitating subsequent maintenance and replacement.

[0030] In this embodiment, the included angle between the first circuit board 1 and the second circuit board 2 is 0-90 degrees.

[0031] Specifically, the angle setting can be adjusted according to the actual internal space layout of the POS machine and the circuit board connection requirements to achieve the best installation effect and space utilization. For example, when the internal space of the POS machine is relatively compact, the angle can be set to a smaller angle to reduce the space occupied by the circuit board structure in the horizontal direction; while when the space is relatively spacious, the angle can be set to a larger angle to facilitate the connection and wiring of the circuit board.

[0032] In this embodiment, the first circuit board 1 is provided with a connecting post 8, and the second circuit board 2 is provided with a connecting hole 9.

[0033] Specifically, the design of the connecting post 8 and the connecting hole 9 in the above structure is used to connect the circuit board to the internal structure of the POS machine, thereby fixing the circuit board.

[0034] This utility model discloses a mold for producing the internal circuit board structure of a POS machine, including an upper mold 10 and a lower mold 11. A first cavity 12 is provided between the upper mold 10 and the lower mold 11 for accommodating a first circuit board 1, a second circuit board 2, a connecting circuit board 6, and forming a first injection molded plate 4 and a second injection molded plate 5. The upper mold 10 is provided with an inlet and a first inlet channel 13. The inlet channel communicates with the first cavity 12 and the first inlet channel 13. The first cavity 12 is provided with a positioning pin 14 for positioning the first circuit board 1 and a cavity post 15 for adapting to the shape of the product.

[0035] In practice, the integrally formed first circuit board 1, second circuit board 2, and connecting circuit board 6 are placed into the first cavity 12. During placement, the first circuit board 1, second circuit board 2, and connecting circuit board 6 are positioned by a cavity consistent with the product shape and positioning pins 14. Then, the upper mold 10 and lower mold 11 are closed, and plastic raw material is injected into the first feeding channel 13 through the feeding port. The plastic raw material enters the first cavity 12 through the first feeding channel 13 and wraps the outer sides of the first circuit board 1 and second circuit board 2 in the first cavity 12 to form the first injection plate 4 and the second injection plate 5. The first injection plate 4 and the second injection plate 5 are integrally formed with the first circuit board 1 and the second circuit board 2. Finally, the upper mold 10 and lower mold 11 are opened, and the formed circuit board structure is taken out.

[0036] The design of the above mold allows the circuit board structure and injection plate to be formed in one go, which improves the production efficiency and quality of the product. At the same time, the positioning pins 14 and cavity pillars 15 inside the mold can ensure the precise positioning and shape adaptation of the product, thereby improving the product's accuracy and stability.

[0037] In this embodiment, the upper mold 10 and the lower mold 11 are further provided with a second cavity 16 for molding small parts of the product, and also include a second feeding channel 17, which is connected to the first feeding channel 13 and the second cavity 16 respectively.

[0038] Specifically, this design allows the mold to not only produce circuit board structures but also related small parts simultaneously, further improving production efficiency and mold utilization. The second cavity 16 can be flexibly adjusted according to actual needs to adapt to the production requirements of different small parts. The connection between the second feed channel 17, the first feed channel 13, and the second cavity 16 ensures that plastic raw materials can smoothly enter the second cavity 16 for injection molding. Simultaneously, this integrated production mode helps reduce material waste and energy consumption during the production process, lowering production costs and improving the company's economic benefits.

[0039] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
