[0020] 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.

[0021] Example

[0022] See Figures 1 to 3As shown, a circuit board with an edge protection structure includes a circuit board body 1, a protective strip 2 along the edge of the circuit board body, and a C-shaped groove 3 on the side of the protective strip. In this embodiment, the circuit board body is a conventional structure of the prior art, so it is not described in detail. The protective strip is an insulating plastic structure. Furthermore, to improve its installation stability and reliability, a locking protrusion 4 is integrally formed on the inner wall of the C-shaped groove; the circuit board body has several locking recesses 5; the size of the locking protrusion matches the size of the locking recesses. During installation, the locking protrusion, under the action of the protective strip itself, can be firmly clamped at the edge of the circuit board body, and the locking protrusion is engaged in the locking recesses for positioning, preventing it from loosening or falling off.

[0023] During assembly, the edge of the circuit board body is inserted into the C-shaped groove, and the locking protrusion is locked into the locking recess for positioning.

[0024] Furthermore, in this embodiment, the inner wall of the C-shaped groove is provided with strip-shaped protrusions 6, and the top and bottom surfaces of the edge of the circuit board body are provided with strip-shaped protrusions 7; the strip-shaped protrusions engage and limit the strip-shaped protrusions. Through the above structure, the connection between the edge of the protective strip and the circuit board body can be prevented from being unstable, preventing loosening or falling off, which is beneficial to improving the protection of the edge of the circuit board.

[0025] In this embodiment, the width of the C-shaped groove matches the thickness of the circuit board body. Furthermore, in this embodiment, the top and bottom edges of the protective strip are both inclined surfaces 8. These inclined surfaces are primarily for aesthetic purposes and also to prevent interference with the assembly of electronic components on the circuit board.

[0026] This utility model has positive effects: The structure of this utility model is reasonably designed. It has a protective strip on the edge of the circuit board body, and a locking protrusion and a locking recess area. After installation, the locking protrusion and the locking recess area can be used to achieve connection and positioning, ensuring the convenience and stability of installation, and improving the stability and reliability of use. In addition, it is also provided with strip-shaped teeth that cooperate with the strip-shaped protrusion to lock in place, preventing loosening or falling off, improving the effectiveness of use, and having strong applicability.
