The terms such as "first," "second," and the like, as used in this disclosure, are used for distinguishing one element from another and not necessarily for order or importance. Furthermore, the following description, when taken in conjunction with the accompanying drawings, like reference numerals designate the same or similar elements in different drawings.

Referring to fig. 1-6, the present disclosure provides a PCB board securing assembly that may be used to mount a PCB board 30 on a housing 40 of an electronic device. The PCB board fixing assembly may include a snap structure 10, and in particular, the snap structure 10 may include a first limiting portion 11, a main body 12, and a second limiting portion 13. The first limiting part 11 and the second limiting part 13 may be laterally protruded on the main body 12, so that the fastening structure 10 may be integrally formed, thereby ensuring the reliability of fixing the PCB board 30. Also, the first and second stopper portions 11 and 13 may be provided at both ends of the main body 12 at intervals in the height direction of the main body 12 (i.e., in the vertical direction in the drawing direction shown in fig. 1). The fastening structure 10 may be configured such that the second limiting portion 13 can sequentially pass through the limiting hole 21 formed in the through hole 31 of the PCB board 30 and the limiting hole 21 formed in the housing 40 in the vertical direction, and the PCB board 30 and the housing 40 are fastened between the first limiting portion 11 and the second limiting portion 13, so that the PCB board 30 is clamped between the first limiting portion 11 and the second limiting portion 13. The main body 12 may be formed with a breaking slot 14 extending from the bottom end to the top end, and the two sidewalls of the breaking slot 14 are moved toward each other by applying an external force, so that the second limiting portion 13 can be pressed in a horizontal direction, thereby deforming the fastening structure 10, and the fastening structure 10 can sequentially pass through the through hole 31 and the limiting hole 21, and the breaking slot 14 can also elastically reset and be blocked on the end wall of the limiting hole 21 after the second limiting portion 13 passes through the limiting hole 21 and the external force is removed, so as to fix the PCB board 30 on the housing 40. The top of the breaking slot 14 may be configured as a cone, and the cone structure may gradually decrease from bottom to top, so that when the worker presses the first limiting portion 11 downwards to apply force, the second limiting portion 13 is more easily retracted when passing through the via hole 21. Moreover, when the buckle structure 10 is installed in place, the first limiting part 11 leaks outside the PCB board 30, and since the width of the breaking groove 14 at the first limiting part 11 (the left-right direction of the drawing direction shown in fig. 4) is smaller than that of the breaking groove 14 at other positions, the elasticity of the first limiting part 11 is smaller than that of the breaking groove 14 at other positions, so that the first limiting part 11 is not easy to deform, and is not easy to deform when impacted in the use process, thereby ensuring the stability of the buckle structure 10 to fix the PCB board 30. In the embodiment provided by the present disclosure, in order to improve the fixing strength of the PCB board 30, the PCB board fixing assembly may be provided in plurality at intervals.

Through above-mentioned technical scheme, use the PCB board fixed subassembly that this disclosure provided to fix PCB board 30 on casing 40, through set up first spacing portion 11 and second spacing portion 13 respectively at the main part 12 both ends of buckle structure 10 to set up through the bottom to the top extend and the top is constructed as conical structure's break slot 14, make buckle structure 10 easy dismouting and joint strength high, first spacing portion 11 is difficult to be out of shape more, thereby guarantees buckle structure 10 to the fixed stability of PCB board 30.

In the embodiment provided by the disclosure, after the buckle structure 10 is clamped into the shell 40, the buckle structure 10 is restored, the first limiting part 11 can be pressed down on the top surface of the PCB 30, and the fitting surface 12a is configured into a plane matched with the structure of the PCB 30, so that the contact area of the first limiting part 11 and the PCB 30 is increased, the pressing effect of the first limiting part 11 on the PCB 30 is further improved, and the stability of the buckle structure 10 on the fixation of the PCB 30 is ensured.

Referring to fig. 1, 4 and 8, the PCB board fixing assembly may further include a support structure 20, the support structure 20 may be used for being mounted on the housing 40, and the support structure 20 may be supported on the bottom surface of the PCB board 30, and the limiting hole 21 may be formed in the top surface of the support structure 20 for supporting the PCB board 30, so that the second limiting portion 13 may extend into and be elastically clamped, so that the PCB board fixing assembly has downward pressure and upward supporting force on the PCB board 30, so that the PCB board 30 may be stably clamped between the fastening structure 10 and the support structure 20, and reliability of fixing the PCB board 30 of the PCB board fixing assembly is ensured.

Referring to fig. 7, a limiting groove 22 may be disposed in the supporting structure 20, the limiting groove 22 may be disposed below the limiting hole 21, and a groove wall of the limiting groove 22 may be used to abut against a side surface of the fastening structure 10, so as to prevent the fastening structure 10 from rotating along an axis of the limiting hole 21 when fixing the PCB board, and ensure stability and reliability of the fastening structure 10 during use.

Referring to fig. 4 and 8 and fig. 10 and 11, a stepped surface 23 may be formed at an end of the support structure 20 at an end of the limiting hole 21 remote from the PCB board 30 for the second limiting portion 13 to be engaged. When the buckle structure 10 goes deep into place downwards and elastically resets along the horizontal direction, the top surface of the second limiting part 13 can be clamped on the bottom surface of the step surface 23, so that the limit of the buckle structure 10 along the vertical direction is realized, and the PCB 30 is stably clamped between the first limiting part 11 and the second limiting part 13.

Referring to fig. 4 and 9, the second limiting parts 13 may be configured as a tapered wedge structure from top to bottom so that the second limiting parts 13 pass through the through holes 31 and the limiting holes 21, and when the buckle structure 10 is installed by applying pressure downward, the two second limiting parts 13 can be easily folded through the through holes 31 to improve the fixing efficiency of the PCB board. Meanwhile, the outer circumferential surface of the wedge structure may be constructed as a smooth curved surface, so that the second limiting part 13 can be effectively prevented from scratching the PCB 30 or the housing 40 during the extending process. When the supporting structure 20 has the step surface 23, the top surface of the wedge-shaped structure may be configured into a plane that can be mutually attached to the step surface 23, so as to increase the clamping area, ensure the firmness of the clamping connection between the clamping structure 10 and the supporting structure 20, and ensure the stability of the fixing of the PCB board 30. The width of the breaking groove 14 located at the second limiting part 13 gradually increases from top to bottom, so that the second limiting part 13 is easier to shrink inwards to deform when extending into the PCB 30 and the supporting structure 20, the installation efficiency of the buckle structure 10 is effectively improved, and labor can be saved.

Referring to fig. 4 and 9, the side of the body 12 for interference fit with the limiting hole 21 may be configured as a rounded surface.
