Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Referring to fig. 1, the circuit board mounting structure of the present utility model includes a circuit board body 1 and a mounting base 2, wherein a plurality of mounting holes 11 are formed at the edge of the circuit board body 1, the mounting base 2 is cooperatively connected with the mounting holes 11, and the circuit board is fixed by a plurality of mounting bases 2.

Referring to fig. 2, the mounting base 2 includes a vertical plate section 21 and a connecting plate section 22, wherein a U-shaped plate 23 is fixedly connected to the middle of the side surface of the vertical plate section 21, the U-shaped plate 23 has elastic plate capability, and two ends of the U-shaped plate can be close to each other or be far away from each other when being stressed, and are elastically deformed; the connecting plate section 22 is formed by bending the lower end of the vertical plate section 21 horizontally to the side where the U-shaped plate 23 is located, or is fixedly connected to the lower end of the vertical plate section 21 in other manners, such as welding, at the lower end of the vertical plate section 21, two retention holes 26 are formed in the surface of the connecting plate section 22, and the connecting plate section 22 can be fixed on a fixing structure of a mounting circuit board, such as a chassis, a casing, etc., in a riveting or threaded connection manner. A threaded pipe 24 is fixedly connected above the other end of the U-shaped plate 23, a limiting ring 25 coaxial with the threaded pipe 24 is fixed at the lower end of the threaded pipe 24, a screw 3 is connected above the threaded pipe 24 in a threaded manner, and the threaded pipe 24 is connected with the mounting hole 11 in a plug-in manner.

During installation, each mounting hole 11 of the circuit board body 1 is aligned with the threaded pipe 24 and pressed downwards, the threaded pipe 24 is inserted into the mounting hole 11, at the moment, the screw 3 is screwed in the threaded pipe 24, the head of the screw 3 and the limiting ring 25 are respectively clamped on the upper surface and the lower surface of the circuit board body 1, the circuit board body 1 is limited, and the circuit board body 1 can be quickly installed and fixed. Because the U-shaped plate 23 is elastically bendable, when vibration or shake occurs, the circuit board body 1 deflects in the transverse direction, the threaded pipe 24 moves along with the vibration or shake, the threaded pipe 24 drives the U-shaped plate 23 to elastically deform, and the two end parts of the U-shaped plate 23 are horizontally and transversely bent, so that damage of the vibration or shake to the circuit board body 1 is reduced. In addition, because the U-shaped plate 23 is tightly bent in the transverse direction, the deformation of the U-shaped plate 23 is small, the capacity of resisting vibration and shake is strong, the circuit board body 1 cannot generate excessive vibration and shift due to the deformation of the U-shaped plate 23, the installation is stable, and the resistance to natural shake is strong.

In addition, in order to strengthen the strength of the mount 2, reinforcing ribs 27 are fixedly connected to the bent portions of the connection plate section 22 and the vertical plate section 21.

In this embodiment, the vertical plate section 21 is made of rigid materials such as hard plastic or stainless steel, the upper end of the vertical plate section 21 is higher than the uppermost end of the threaded pipe 24, the gap width between the vertical plate section 21 and the threaded pipe 24 is slightly larger than the distance from the mounting hole 11 to the edge of the circuit board body 1, the difference indicates that a certain gap is reserved between the edge of the circuit board body 1 and the vertical plate section 21 after the circuit board body is mounted, and the gap width is 2mm. When vibration or shake occurs, the U-shaped plate 23 deforms in the transverse direction, and when the vibration is overlarge, the edge of the circuit board body 1 can be limited by abutting the upper end of the vertical plate section 21, so that the maximum limit of the movement of the threaded pipe 24 in the direction close to the vertical plate section 21 is limited, and the protection is improved.

The above examples are merely illustrative of the preferred embodiments of the present utility model and are not intended to limit the spirit and scope of the present utility model. Various modifications and improvements of the technical scheme of the present utility model will fall within the protection scope of the present utility model without departing from the design concept of the present utility model, and the technical content of the present utility model is fully described in the claims.
