Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the following embodiments are specifically described with reference to the accompanying drawings.
In this embodiment, the arcuate two-piece shield 100 is mounted on the electronic device to be shielded on a circuit board in a smart watch.
FIG. 1 is a side cross-sectional view of an arcuate two-piece shield in an embodiment of the invention; fig. 2 is a top view of an arcuate bracket in an embodiment of the present invention; fig. 3 is a top view of an arc-shaped cover in an embodiment of the present invention.
As shown in fig. 1 to 3, the arc-shaped two-piece shield case 100 includes an arc-shaped bracket 10 and an arc-shaped cover 20.
The arc-shaped support 10 is prepared by stretch forming, punching, bending and dotting.
The arc-shaped support 10 is arranged on a printed circuit board 30(PCB) around the electronic device 40 that needs to be shielded. The curved support 10 surrounds a region of the electronic device 40 formed with a plurality of curved segments.
The arc-shaped bracket 10 comprises a horizontal section 11, a vertical section 12 and a flange edge 13 extending horizontally outwards. One end of the vertical section 12 is vertically connected with the horizontal section 11, the joint is in round angle smooth transition, and the other end is in smooth connection with the flange edge 13.
The flange 13 is in contact with the printed circuit board 30 and soldered thereto, and extends toward a side away from the electronic device 40. The horizontal section 11 is disposed at an end of the vertical section 12 remote from the printed circuit board 30 and extends toward an edge near the electronic device 40. A through hole for passing the electronic device 40 is formed in the middle of the horizontal section 11.
The arc cover 20 is matched with the arc support 10 in shape and covers the arc support 10. A cover flange 21 is provided under the arc-shaped cover 20. The lid flange 21 is located above the flange 13.
The arc-shaped cover 20 is formed by drawing a stainless steel or copper-based material having a low hardness by a drawing process. The minimum thickness of the molded arc-shaped lid 20 is 0.15mm, and in addition, the arc-shaped lid 20 manufactured by the stretch molding process has an additional lid flange 21, and the length of the lid flange 21 extending outward is about 0.1 mm. A through hole 22 is formed above the molded arc-shaped cover 20 by a punching process. The through hole 22 can let the electronic device 40 pass through, and after the electronic device 40 passes through, the copper foil paper 23 is pasted on the through hole 22 for shielding again.
In summary, in the case of the arc-shaped two-piece shield in the embodiment, the process is upgraded without adding new production equipment or new materials, and the cost is not increased, so that the problem that the arc-shaped two-piece shield is lacking in the prior art is effectively solved, and the shape design limitation of the shield is solved.
In this embodiment, the arc-shaped cover is made of stainless steel or copper-based material with low hardness, which is advantageous for implementing the stretching process because the arc-shaped cover is soft. In addition, the arc-shaped cover prepared by adopting the stretching process can generate a cover flange edge, but the size of the arc-shaped two-piece shielding cover is not influenced due to the small size of the arc-shaped two-piece shielding cover. Furthermore, the flange of the cover can also improve the structural strength of the arc-shaped two-piece shield.
In addition, the arc-shaped two-piece shielding cover in the embodiment assists in shielding through the through holes and the copper foil paper, so that a convex bag structure on a conventional shielding cover is eliminated, the height of the shielding cover is reduced, the inner space of a product is reduced, meanwhile, the process difficulty of the shielding cover is also reduced, and the flatness of the product is effectively guaranteed.
Further, in the present embodiment, the area of the arc bracket formed around the electronic device in the arc two-piece shield case has a plurality of arc segments. However, in practical production application, the shape of the arc-shaped two-piece shielding case can be changed according to the shape of a specific product, and the arc-shaped two-piece shielding case can be extended to the production and manufacture of a circular shielding case, an oval shielding case and a semicircular semi-square shielding case, and the application mode of the arc-shaped two-piece shielding case can be flexibly adjusted according to the difference of the product.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present application without departing from the spirit and scope of the application. Thus, if such modifications and variations of the present application fall within the scope of the claims of the present application and their full equivalents, the present application is intended to include such modifications and variations.
