Description

Technical Field

[0001] This utility model relates to the field of printed circuit board technology, and in particular to a bend-resistant printed circuit board. Background Technology

[0002] Printed circuit boards, also known as circuit boards, PCBs, high-frequency boards, ultra-thin circuit boards, etc., make circuits miniaturized and more intuitive. They play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. Circuit boards are the supporting components for circuit elements and devices in electronic products, greatly reducing the size of electrical appliances and meeting modern people's demand for high portability and high performance. They provide electrical connections between circuit elements and devices.

[0003] Referring to the existing patent publication number: CN216600227U, a printed circuit board includes a protective layer, a wiring layer fixedly connected to the bottom of the protective layer, an anti-interference layer fixedly connected to the bottom of the wiring layer, a signal layer fixedly connected to the bottom of the anti-interference layer, and an anti-oxidation layer fixedly connected to the bottom of the signal layer. This utility model provides an anti-interference layer in the middle of the printed circuit board, which can isolate the wiring layer and the signal layer, effectively reduce electromagnetic interference, and improve the stability of the printed circuit board.

[0004] However, existing printed circuit boards have poor overall strength in actual use, making them prone to bending and deformation when subjected to external forces. This not only affects the appearance of the circuit board, but may also damage the electronic components on the circuit board, thereby affecting the overall performance and reliability of the circuit board. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bend-resistant printed circuit board. This invention utilizes a support plate (first and second) constructed on the back of the circuit board to provide support. The support plates are connected by reinforcing members, and the connection strength of these reinforcing members can be adjusted using adjustment and transmission components. This improves the overall support strength of the circuit board, increases its rigidity and tension, effectively reduces bending under pressure, and enhances its bend resistance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A bend-resistant printed circuit board, comprising:

[0008] The main body, as the basic structure of the printed circuit board, carries circuit components and connecting lines;

[0009] Support plate one is installed on both sides of the back of the main body, and a first reinforcing member is connected to each opposite side of support plate one;

[0010] Support plates two are installed on the back of the main body and are staggered with support plate one. Connectors are connected between support plates two.

[0011] An adjustment assembly and a transmission assembly are constructed between the first reinforcing member and the connecting member.

[0012] The present invention further provides that the adjusting component includes: a threaded sleeve and a thread;

[0013] The threads are all formed at the end of the first reinforcing member away from the support plate, and the threaded sleeve is connected to the threaded surface of the first reinforcing member.

[0014] The present invention is further configured such that the directions of the threads are opposite.

[0015] The present invention is further configured such that the transmission assembly includes: a second reinforcing member and an eccentric wheel;

[0016] The second reinforcing member is connected to one side of the two opposing support plates, and the eccentric wheel is mounted on the surface of the threaded sleeve.

[0017] The present invention is further configured such that the eccentric wheel contacts the second reinforcing member, and the second reinforcing member is located inside the connecting member.

[0018] The present invention is further configured such that magnets are installed on the inner sides of both the first support plate and the second support plate.

[0019] The present invention is further configured such that the surface of the main body is constructed with elements, and mounting holes are provided around the perimeter of the surface of the main body.

[0020] The beneficial effects of this utility model are as follows: By constructing support plate one and support plate two on the back of the circuit board, the circuit board can be supported to a certain extent. The support plates can be connected by reinforcing members, and the connection strength of the reinforcing members can be adjusted by adjusting components and transmission components to improve the overall support strength of the circuit board, increase the hardness and tension of the circuit board, thereby effectively reducing the bending of the circuit board after being compressed and improving the bending resistance.

[0021] 1. This anti-bending printed circuit board, through the combination of adjustment and transmission components, has support plate one and support plate two constructed on the back of the circuit board to provide certain support for the circuit board. The support plates can be connected by reinforcing members, and the connection strength of the reinforcing members can be adjusted accordingly by the adjustment and transmission components to improve the overall support strength of the circuit board, increase the hardness and tension of the circuit board, thereby effectively reducing the bending of the circuit board under pressure and improving the anti-bending effect.

[0022] 2. This anti-bending printed circuit board, by setting up support plate one, support plate two and magnet, the support plate one and support plate two are constructed on the back of the circuit board to support the circuit board to a certain extent, so that the circuit board can be raised to a certain height to facilitate air circulation at its bottom and improve heat dissipation. At the same time, when the circuit board is connected, the magnetic attraction effect between the magnet and the mounting part can be used to simply limit the connection, preventing movement or displacement during installation and improving the stability of the connection.

[0028] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0029] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0030] In the description of this patent, it should be understood that the terms “center,” “upper,” “lower,” “front,” “back,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this patent and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this patent.

[0031] In the description of this patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0032] Reference Figures 1 to 4 A bending-resistant printed circuit board includes: a main body 1, serving as the basic structure of the printed circuit board, supporting circuit elements and connecting lines; a support plate 3, installed on both sides of the back of the main body 1, with a first reinforcing member 6 connected to each opposite side of the support plate 3 to provide additional support for the circuit board; the first reinforcing member 6 connecting the support plates 3 further enhancing the bending strength of the circuit board; and a second support plate 4, all installed on the back of the main body 1 and staggered with the support plates 3, with connecting members 7 connecting the support plates 4 to form a staggered support structure, which can more effectively disperse and resist external forces, improving the overall stability of the circuit board; an adjustment component and a transmission component are constructed between the first reinforcing member 6 and the connecting member 7, which can adjust the support tension of the circuit board, thereby better adapting to and resisting external forces and preventing the circuit board from bending or being damaged.

[0033] Specifically, refer to Figures 2 to 4 The adjustment component includes a threaded sleeve 10 and a thread 9. The thread 9 is constructed at the end of the first reinforcing member 6 away from the support plate 3. The threaded sleeve 10 is connected to the surface of the first reinforcing member 6 with the thread 9. Through this implementation, the personnel can rotate the threaded sleeve 10, and the movement of the threaded sleeve 10 can drive the first reinforcing member 6 with the thread 9 to generate a certain tension.

[0034] Furthermore, the threads 9 are arranged in opposite directions. This design allows the two first reinforcing members 6 to expand in opposite directions, thereby generating stronger tension to improve the support strength between the support plates 3.

[0035] Specifically, refer to Figures 2 to 4The transmission assembly includes a second reinforcing member 8 and an eccentric wheel 11. The second reinforcing member 8 is connected to the opposite side of the support plate 2 4. The eccentric wheel 11 is mounted on the surface of the threaded sleeve 10. In this embodiment, the threaded sleeve 10 can rotate and drive the eccentric wheel 11 to rotate together. The second reinforcing member 8 and the connecting member 7 provide additional support and reinforcement for the circuit board in another horizontal direction.

[0036] Furthermore, the eccentric wheel 11 contacts the second reinforcing member 8, and the second reinforcing member 8 is located inside the connector 7. This design ensures a tight connection, so that the eccentric wheel 11 can also provide movement tension to the second reinforcing member 8 after rotation.

[0037] Furthermore, magnets 5 are installed on the inner sides of both support plate 3 and support plate 4. With this design, the circuit board can be simply limited by the magnetic attraction between the magnets 5 and the mounting parts when they are connected, so as to avoid any movement or displacement during installation.

[0038] Specifically, refer to Figures 1 to 2 The surface of the main body 1 is constructed with components 2, and mounting holes are provided around the surface of the main body 1. In this embodiment, components 2 are the basic units that constitute the circuit board, so that the circuit board can be connected with various components and produce corresponding functions. The design of the mounting holes facilitates the positioning of components 2 on the main body 1.

[0039] Working Principle: When using this utility model, support plate 3 and support plate 4 are first constructed on the back of the circuit board to provide certain support for the circuit board, allowing the circuit board to be raised to a certain height to facilitate air circulation and improve heat dissipation. At the same time, when the circuit board is connected, the magnetic attraction effect between the magnet 5 and the mounting part can be used to simply limit the connection, preventing movement or displacement during installation and improving the stability of the connection. The support plates can be connected by reinforcing members, and the connection strength of the reinforcing members can be adjusted by adjusting components and transmission components. During the rotation of the threaded sleeve 10, the first reinforcing member 6 with thread 9 can be driven to move away from each other to generate a certain tension. When the threaded sleeve 10 drives the eccentric wheel 11 to move, it can also push the second reinforcing member 8 to generate a certain tension, thereby improving the overall support strength of the circuit board, increasing the hardness and tension of the circuit board, and thus effectively reducing the bending of the circuit board under pressure and improving the bending resistance.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
