Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to a circuit board with an auxiliary mounting structure. Background Technology

[0002] Circuit boards are important electronic components, serving as carriers and supports for the electrical connections of electronic components. A circuit board consists of a circuit board body and mounting holes. When installing a circuit board into a housing, the circuit board body is placed on the housing, ensuring that the mounting holes on the housing and the mounting holes on the circuit board are horizontally and vertically aligned, and then screws are tightened.

[0003] However, in actual use, it has been found that aligning the mounting holes on the circuit board and the housing is difficult for users. Furthermore, after aligning the mounting holes on the circuit board and the housing, it is necessary to maintain the stability of the circuit board's positioning to prevent the screw from shifting during insertion, which would prevent the screw from being inserted into the mounting hole on the housing. This would affect the installation of the circuit board on the housing, making the installation inconvenient and affecting work efficiency. Therefore, a circuit board with an auxiliary installation structure is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a circuit board with an auxiliary installation structure to solve the problems mentioned in the background art.

[0026] In the diagram: 100, main body of circuit board; 101, mounting hole; 102, straight groove; 200, auxiliary mounting structure; 201, elastic sheet; 202, snap-fit ​​through hole; 203, upper cover plate; 204, first sleeve; 205, positioning strip; 206, internal thread groove; 207, lower cover plate; 208, second sleeve. Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides, for example Figure 1-3 The circuit board shown includes a circuit board body 100, an auxiliary mounting structure 200, and an elastic sheet 201. Mounting holes 101 are provided at the corners of the circuit board body 100. The auxiliary mounting structure 200 is fixedly mounted to the mounting holes 101 of the circuit board body 100. The elastic sheet 201 is fixedly connected to the port of the auxiliary mounting structure 200. A snap-fit ​​hole 202 is provided in the middle of the elastic sheet 201. The auxiliary mounting structure 200 is made of elastic rubber, and the elastic sheet 201 is circular and communicates with its upper and lower sides. When the circuit board body 100 is installed and positioned on the housing, a screw is first inserted into the snap-fit ​​hole 202 of the elastic sheet 201, and the screw is then pressed together. The bottom end of the wire extends to the lower part of the circuit board body 100. When the circuit board body 100 is placed on the housing, the surface of the housing presses the screw, causing it to bulge upwards. This causes the elastic plate 201 to arch upwards and deform. As the circuit board body 100 moves on the housing, when the mounting hole 101 on the circuit board body 100 aligns with the mounting hole on the housing, the screw automatically inserts into the mounting hole of the housing using the elastic downward pressure provided by the elastic plate 201. This completes the positioning between the circuit board body 100 and the housing. Then, simply tightening the screw completes the installation of the circuit board body 100 on the housing. This makes the positioning and installation operation of the circuit board body 100 on the housing more convenient and efficient, improving work efficiency.

[0029] The auxiliary mounting structure 200 includes an upper cover plate 203, a lower cover plate 207, and a connecting component. The upper cover plate 203 is located at the top of the mounting hole 101, and the elastic sheet 201 is fixedly connected to the inner side of the upper cover plate 203. The lower cover plate 207 is located at the bottom of the mounting hole 101, and the connecting component is disposed inside the mounting hole 101. The connecting component is used to connect and fix the upper cover plate 203 and the lower cover plate 207. The cooperation between the upper cover plate 203 and the lower cover plate 207 positions the mounting holes 101 on the upper and lower sides of the circuit board body 100, so that the elastic sheet 201 can be installed at the port position of the mounting hole 101 of the circuit board body 100. The connecting component, by connecting the upper cover plate 203 and the lower cover plate 207, can ensure the limiting and fixing of the upper cover plate 203 and the lower cover plate 207 at the port positions of the mounting holes 101 on both sides.

[0030] Furthermore, the connecting assembly includes a first sleeve 204 and a second sleeve 208. One end of the first sleeve 204 is fixedly connected to the middle of the upper cover plate 203, and an internal threaded groove 206 is formed on the inner wall of the first sleeve 204. One end of the second sleeve 208 is fixedly connected to the middle of the lower cover plate 207, and an external threaded groove is formed on the outer wall of the second sleeve 208. The first sleeve 204 is threadedly connected to the external threaded groove of the second sleeve 208 through the internal threaded groove 206. When the upper cover plate 203 and the lower cover plate 207 are assembled at the mounting hole 101 position of the circuit board body 100, it is only necessary to insert the outer wall of the first sleeve 204 with the upper cover plate 203 into the mounting hole 101. Inside the mounting hole 101, the second sleeve 208 with the lower cover plate 207 is inserted into the inside of the first sleeve 204. By rotating the lower cover plate 207, the second sleeve 208 and the first sleeve 204 are connected by threaded pressing, thereby clamping the lower cover plate 207 and the upper cover plate 203 on both sides of the circuit board body 100. This achieves the installation and fixation of the lower cover plate 207 and the upper cover plate 203 at the mounting hole 101 position on the circuit board body 100, while making the upper cover plate 203 and the lower cover plate 207 detachable from the circuit board body 100 for subsequent disassembly and assembly.

[0031] Additionally, a limiting component is provided between the first sleeve 204 and the mounting hole 101. This limiting component limits the radial rotation of the first sleeve 204 within the mounting hole 101. The limiting component includes a straight groove 102 and a positioning strip 205. The straight groove 102 is formed on the inner wall of the mounting hole 101, and the positioning strip 205 is fixedly connected to the outer wall of the first sleeve 204. The outer wall of the positioning strip 205 is slidably connected to the inner wall of the straight groove 102. When the first sleeve 204 is inserted into the mounting hole 101, it passes through the mounting hole 101... The straight groove 102 on the inner wall limits and guides the positioning strip 205 on the outer wall of the first sleeve 204. After the positioning strip 205 is inserted into the straight groove 102, it can limit the radial movement of the first sleeve 204 in the mounting hole 101. This ensures that the first sleeve 204 is radially limited in the mounting hole 101, so that the second sleeve 208 will not drive the first sleeve 204 to rotate when it rotates in the first sleeve 204, making the threaded connection between the second sleeve 208 and the first sleeve 204 more convenient.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
