Description

Technical Field

[0001] This application relates to the field of PCB mounting component technology, and in particular to a multi-PCB mounting structure. Background Technology

[0002] A PCB, or Printed Circuit Board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical interconnection. In electronic devices, from electronic watches, calculators, computers, and communication electronic equipment to military weapon systems, printed circuit boards are used to electrically interconnect various electronic components containing integrated circuits.

[0003] Currently, the common PCB mounting components on the market typically install the PCBs one by one and then fix them with screws. This type of mounting component not only requires a large number of screws and related parts when assembling PCBs, but also has low assembly efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a multi-PCB board mounting structure. The technical problem it solves is that existing mounting components for multiple PCBs require a large number of screws for fixing, resulting in low assembly efficiency. The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A multi-PCB mounting structure includes a mounting motherboard. The lower end face of the mounting motherboard has several evenly distributed mounting slots. The upper end face of the mounting motherboard has several evenly distributed support plates fixedly disposed thereon. The two end faces of the support plates have several evenly distributed mounting components fixedly disposed thereon. Each mounting component includes a first mounting plate and a second mounting plate. The lower end faces of both the first and second mounting plates are fixedly connected to the upper end face of the mounting motherboard. A gap is provided between the first and second mounting plates, and this gap communicates with the mounting slots.

[0005] Furthermore, the mounting motherboard includes several vertical plates, and several evenly distributed horizontal plates are fixedly connected between two adjacent vertical plates. The support plate is fixedly disposed on the upper surface of the vertical plates, and a cavity is formed between two adjacent horizontal plates. The mounting slot is connected to the cavity, and the cavity and the two opposing mounting slots form a mounting position.

[0006] Furthermore, a protrusion is fixedly provided on the lower part of the side end face of the support plate. The protrusion is located between the first mounting plate and the second mounting plate, and the outer end face of the protrusion and the upper side end face of the support plate form a limiting contact surface.

[0007] Furthermore, the limiting contact surface includes a common wall surface, a guide end surface, and a contact end surface, wherein the common wall surface and the contact end surface are connected through the guide end surface, and the guide end surface is an inclined surface.

[0008] Furthermore, a core-pulling hole is provided on the lower end face of the protrusion.

[0009] Furthermore, positioning posts are fixedly provided on the lower end face of the vertical plates on both sides of the mounting motherboard.

[0010] The beneficial effects of this utility model are: by setting several mounting slots and mounting components on the mounting motherboard, a modular design for mounting a large number of PCB boards is realized, which significantly reduces the number of screws required for traditional individual mounting and fixing, simplifies the assembly operation of a single PCB board, and effectively improves the overall assembly efficiency of multiple PCB boards.

[0011] By setting up a common wall and a core-pulling hole, with the top of the core-pulling hole adjacent to the common wall and the core-pulling hole using the common wall as part of its own hole wall, injection molding defects (such as flash, inaccurate dimensions, and surface defects) caused by excessively long cores during the manufacturing of this mounting structure can be avoided, and materials can be saved, reducing production costs.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the utility model will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this utility model. The specific implementation scheme of this utility model is as follows: like Figure 1-2As shown, a multi-PCB board mounting structure includes a mounting motherboard 1. The lower end face of the mounting motherboard 1 has several evenly distributed mounting slots 2. The upper end face of the mounting motherboard 1 is fixedly provided with several evenly distributed support plates 3. The two end faces of the support plates 3 are fixedly provided with several evenly distributed mounting components 4. Each mounting component 4 includes a first mounting plate 41 and a second mounting plate 42. The lower end faces of both the first mounting plate 41 and the second mounting plate 42 are fixedly connected to the upper end face of the mounting motherboard 1. A gap is provided between the first mounting plate 41 and the second mounting plate 42, and this gap communicates with the mounting slots 2. By providing several mounting slots 2 and mounting components 4 on the mounting motherboard 1, a modular design for mounting multiple PCB boards is achieved, significantly reducing the number of screws required for traditional individual mounting and simplifying the assembly operation of a single PCB board, effectively improving the overall assembly efficiency of multiple PCB boards.

[0018] It should be noted that the mounting motherboard 1 includes several vertical plates 11, and several evenly distributed horizontal plates 12 are fixedly connected between two adjacent vertical plates 11. The support plate 3 is fixedly disposed on the upper surface of the vertical plate 11, and a cavity 5 is formed between two adjacent horizontal plates 12. The mounting groove 2 is connected to the cavity 5, and the cavity 5 and the two opposing mounting grooves 2 form a mounting position 6. This structure facilitates the installation of the PCB board and realizes the modularity of the mounting structure.

[0019] like Figure 3 As shown, it should be noted that a protrusion 7 is fixedly provided on the lower part of the side end face of the support plate 3. The protrusion 7 is located between the first mounting plate 41 and the second mounting plate 42. The outer end face of the protrusion 7 and the upper side end face of the support plate 3 form a limiting contact surface 8. The limiting contact surface 8 includes a common wall surface 81, a guide end surface 82, and a contact end surface 83. The common wall surface 81 is the two end faces of the support plate 3 between the first mounting plate 41 and the second mounting plate 42. The top width of the common wall surface 81 is greater than the width of the PCB board, which allows the PCB board to be smoothly pushed into the mounting groove 2 from top to bottom. The common wall surface 81 and the contact end surface 83 are connected by the guide end surface 82. The guide end surface 82 is an inclined surface. The setting of the guide end surface 82 can restrict the movement of the PCB and allow it to be smoothly assembled.

[0020] Furthermore, the lower end face of the protrusion 7 is provided with a core-pulling hole 9; the core-pulling hole 9 uses the common wall surface 81 as part of its own hole wall, which can avoid injection molding defects (flash, inaccurate dimensions and surface defects, etc.) caused by excessive core pulling during the manufacturing of the mounting structure, and save materials and reduce production costs.

[0021] like Figure 4As shown, it should be noted that positioning posts 10 are fixedly provided on the lower end face of the vertical plates 11 on both sides of the mounting motherboard 1; the main purpose of this structure is to pre-assemble the mounting structure into other configuration components.

[0022] The working principle and process of this utility model are as follows (taking the installation of a PCB board as an example): Align the two sides of the PCB board with the two opposing mounting slots 2 on the adjacent vertical plate 11, and push the PCB board downward into the mounting slots 2 along the common wall surface 81. During the downward pushing process, the PCB board will pass through the guide end face 82, which will guide and correct the horizontal position of the PCB board. After passing through the guide end face 82, the PCB board continues to descend until the PCB board successfully enters the mounting position 6, completing the assembly.

[0023] The PCB board mounting structure is equipped with several mounting slots 2 and mounting components 4, realizing a modular design for mounting multiple PCB boards, reducing the use of screws and other parts, simplifying assembly, and effectively improving the assembly efficiency of multiple PCB boards.
