[0027] The following is a preferred embodiment of a shielding bracket provided by the present invention that can solve the above technical problems.

[0031] The utility model provides a shielding bracket, including a shielding frame 11, the shielding frame 11 includes a panel 111 and a skirt 112 surrounding the side of the panel 111, a notch is provided on the panel 111, the skirt 112 includes a first bending plate 1121 connected to the panel 111, a second bending plate 1122 located in the notch and connected to the first bending plate 1121, and a third bending plate 1123 located in the notch and connected to the panel 111, the first bending plate 1121, the second bending plate 1122, and the third bending plate 1123 surround to form a continuous annular frame structure, the skirt 112 and the panel 111 form a shielding frame 11 for wrapping a circuit board, the first bending plate 1121 is connected to the panel 111 The second bending plate 1122 is connected to the first bending plate 1121, and the third bending plate 1123 is connected to the panel 111. Since the second bending plate 1122 is connected to the first bending plate 1121, when the shielding frame 11 is stamped, the second bending plate 1122 and the third bending plate 1123 will not overlap, thereby effectively preventing the problem of openings at adjacent positions of the second bending plate 1122 and the third bending plate 1123 after folding, thereby making the shielding effect of the shielding frame 11 better. In this embodiment, the panel 111, the first bending plate 1121, the second bending plate 1122, and the third bending plate 1123 are all made of one piece, which effectively ensures the hardness of the shielding frame 11.
[0032] A limiting structure connected to the panel 111 and used to limit the second bending plate 1122 is provided in the notch. The limiting structure is used to limit the second bending plate 1122 to prevent the second bending plate 1122 bent on the first bending plate 1121 from position deviation, thereby further enhancing the shielding effect.
[0033] The limiting structure is a dovetail plate 1112, and a dovetail groove 11221 is provided at a position corresponding to the second bending plate 1122 and the dovetail plate 1112. The dovetail plate 1112 is clamped in the dovetail groove 11221. Since the dovetail plate 1112 is a special-shaped dovetail plate 1112 with a special-shaped structure is clamped in the dovetail groove 11221, and the dovetail groove 11221 limits the dovetail plate 1112. Since the second bending plate 1122 is at the first bending The plate 1121 is bent, and after the second bending plate 1122 is bent toward the third bending plate 1123, the dovetail plate 1112 is connected in the dovetail groove 11221, thereby limiting the second bending plate 1122 and preventing the second bending plate 1122 from bending again, thereby fixing the position of the second bending plate 1122; in this embodiment, the limiting structure can be the dovetail plate 1112, but is not limited to using only the dovetail plate 1112.
[0034] A maintenance opening 1111 is also provided in the panel 111 , and the maintenance opening 1111 is used to facilitate maintenance and installation of the circuit board in the shielding frame 11 .
[0035] Please refer to Figure 5 , Figure 5 The utility model is a three-dimensional diagram of the upper cover of the shielding bracket, wherein the skirt 112 is provided with a plurality of through holes 1124 with equal spacing, and the through holes 1124 are of a rectangular structure. The shielding bracket is also provided with an upper cover 12 that closes the maintenance port 1111 and is clamped on the skirt 112, and the side of the upper cover 12 is provided with a plurality of connecting plates 121 opposite to the skirt 112, and the connecting plates 121 are arranged around the skirt 112, and the connecting plates 121 are provided with clamping protrusions 122, and the clamping protrusions 122 are opposite to the skirt 112, and the through holes 1124 are used to clamp the connecting plates 1 The snap-fitting protrusions 122 on 21 are used for limiting, so as to facilitate fixing the upper cover 12 on the shielding frame 11. At the same time, the through holes 1124 of the rectangular structure can adapt to the snap-fitting protrusions 122 at different positions on the connecting plate 121, and there is no need to perform corresponding processing on the corresponding positions of each snap-fitting protrusion 122. At the same time, the snap-fitting protrusions 122 can also be connected to the skirt 112. On the one hand, the snap-fitting protrusions 122 can squeeze the skirt 112, and on the other hand, the snap-fitting protrusions 122 can be snapped into the through holes 1124, so that the upper cover 12 is more stably connected to the shielding frame 11.
[0036] A plurality of avoidance grooves 1125 with the same spacing are also provided on one side of the skirt 112 away from the panel 111, which are used to avoid non-welding positions when the circuit board is welded, thereby ensuring the flatness of the welding surface and effectively improving the welding yield.
[0037] Working principle:
[0038] When assembling the shielding bracket, first, bend the stamped shielding frame 11. At this time, the first bending plate 1121 is connected to the panel 111, the second bending plate 1122 is connected to the first bending plate 1121, the third bending plate 1123 is located in the notch and connected to the panel 111, and the dovetail plate 1112 is located in the notch and connected to the panel 111. When bending, the first bending plate 1121 is bent toward one side of the panel 111, and the bending is stopped after bending to a limited position, and the second bending plate 1122 is bent toward the notch. When the second bending plate 1122 is flush with the panel 111, the second bending plate 1122 is stopped, and the third bending plate 1123 is bent. When the bending direction of the third bending plate 1123 is aligned with the bending direction of the second bending plate 1122 When the direction is vertical, stop bending the third bending plate 1123, bend the dovetail plate 1112, and bend the dovetail plate 1112 into the dovetail groove 11221. Furthermore, finally, connect the upper cover 12 to the outside of the shielding frame 11, close the maintenance port 1111, and the snap-in protrusion 122 of the connecting plate 121 of the upper cover 12 is snapped into the through hole 1124 and the skirt 112. Since the second bending plate 1122 is connected to the first bending plate 1121, when the shielding frame is stamped, the second bending plate 1122 and the third bending plate 1123 will not overlap. The bent second bending plate 1122 and the third bending plate 1123, as well as the first bending plate 1121, can form a continuous annular frame structure around, thereby effectively improving the shielding effect.
[0039] In the shielding bracket of this preferred embodiment, when the shielding frame is stamped, the second bending plate is connected to the first bending plate, and the third bending plate is connected to the panel. Since the second bending plate and the third bending plate do not overlap during stamping, when the shielding frame is bent after stamping, the first bending plate, the second bending plate, and the third bending plate can form a continuous annular frame structure, avoiding the opening between the second bending plate and the third bending plate, so that the shielding effect of the shielding frame is better.
[0040] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
