The embodiments described herein are specific embodiments of the present invention, and are intended to be illustrative of the concepts of the present invention, which are intended to be illustrative and exemplary, and should not be construed as limiting the scope of the embodiments of the present invention. In addition to the embodiments described herein, those skilled in the art will be able to employ other technical solutions which are obvious based on the disclosure of the claims and the specification of the present application, and these technical solutions include technical solutions which make any obvious replacement or modification for the embodiments described herein.

The drawings in the present specification are schematic views to assist in explaining the concept of the present invention, and schematically show the shapes of the respective portions and the mutual relationships thereof. It should be noted that for the sake of clarity in showing the structures of the various components of the embodiments of the present invention, the drawings are not drawn to the same scale. Like reference numerals are used to denote like parts.

The structure of a novel lens mounting device is schematically illustrated in fig. 1 to 5, and the novel lens mounting device includes a clip sheet 10, wherein the clip sheet 10 is detachably connected to a mounting hole 21 of a PCB board 20.

Fig. 4 is a schematic structural diagram of the lens 30 of the present invention, and a connecting claw 31 is disposed at the bottom of the lens 30, and the connecting claw 31 is inserted into the mounting hole 21 of the PCB 20 and abutted by the clamping piece 10. In the embodiment shown in fig. 4, the inner side surfaces of the connection claws 31 are inclined outward to form wedge surfaces for better insertion into the mounting holes 21 of the PCB 20.

Fig. 6 is a schematic structural diagram of the clip sheet of the present invention, the clip sheet 10 includes a fixing portion 11 and an abutting portion 12, both of which are integrally formed, the fixing portion 11 is disposed in the notch 211 on the upper portion of the mounting hole 21 and fixed by a screw, and the abutting portion 12 is disposed on the inner side surface of the mounting hole 21.

As an embodiment of the present invention, the engagement piece 10 is made of an elastic material, which is convexly provided toward the direction of the connection claw 31. The protrusion of the engagement piece 10 toward the engagement claw 31 can enhance the pressing of the engagement claw 31 of the lens 30, improving the reliability of the fixation.

As an aspect of the present embodiment, the click piece 10 is made of a spring steel sheet, and the thickness of the click piece 10 is 0.2mm to 0.5 mm. Preferably, clip 10 has a thickness of 0.3 mm. As another embodiment of the present invention, the clip sheet 10 is detachably mounted in the notch 211 of the mounting hole 21 of the PCB board 20, and it can be understood that the size and shape of the notch 211 are matched with the size and shape of the fixing portion 11 of the clip sheet 10.

Fig. 7 is a schematic structural view of another embodiment of the card connecting piece of the present invention, wherein a protrusion 121 is disposed on a side surface of the abutting portion 12, and the protrusion 121 is disposed along a length direction of the abutting portion 12. As an aspect of the present embodiment, the number of the protrusions 121 is not less than two, which are arranged in parallel with each other.

In one aspect of this embodiment, the height of the protrusions 121 is 0.1mm to 0.4 mm. Preferably, the height of the protrusion 121 is 0.2 mm. The arrangement of the protrusion 121 is beneficial to increasing the extrusion of the connecting claw 31 of the lens 30 and improving the reliability of fixation; meanwhile, a gap for ventilation is formed between the protrusions 121, so that negative pressure generated during press fitting of the lens 30 is prevented from affecting press fitting of the connecting claws 31.

That is, after the lens 30 is fixed to the mounting hole 21 of the PCB 20 by clipping, the end of the clip 10 does not protrude out of the mounting hole 21 of the PCB 20. That is, the end of the card tab 10 does not protrude out of the bottom surface of the PCB board 20 to prevent the card tab 10 from interfering with the lens assembly, ensuring the efficiency of the lens assembly.

As another embodiment of the present invention, the number of the locking pieces 10 is plural, and the locking pieces are disposed in the mounting hole 21 of the PCB board 20 and cover the inner side surface of the mounting hole 21. This arrangement is advantageous in improving the reliability of fixing the connecting claws 31 of the lens 30 to the PCB board 20. In some embodiments, the front end of the connecting claw 31 of the lens 30 is provided with a wedge-shaped portion, after the lens 30 and the PCB 20 are pressed and fixed, the wedge-shaped portion passes through the mounting hole 21 and is clamped on the bottom surface of the PCB 20, and this way can effectively prevent the lens 30 from falling off, and ensure the mounting quality of the lens.

Compared with the defects and shortcomings of the prior art, the novel lens mounting device provided by the utility model is convenient and fast to mount, abandons the traditional mode of fixing the lens by gluing the glue solution, adopts the clamping and press mounting for fixation, effectively avoids the influence of the use of the glue solution on the mounting quality of the lens, and realizes the reliable fixation of the lens and the PCB; in addition, the clamping fixation is adopted, and the efficiency of lens installation is improved.
