[0028] In the terms of the present utility model, words such as "first" and "second" are only for descriptive purposes and cannot be construed as indicating or implying relative importance, nor as limiting the order of precedence.

[0029] A shielding bracket provided by the present utility model includes a shielding frame 11. The shielding frame 11 includes a panel 111 and a skirt surrounding the side of the panel 111. The skirt includes a first bending plate 112 located on both sides of the panel 111 respectively and two second bending plates 113 located between the two adjacent first bending plates 112. The first end of the first bending plate 112 is provided with a first protrusion 1123, a second protrusion 1124, and first clearance grooves 1125 located on both sides of the first protrusion 1123. The second end of the first bending plate 112 is provided with a third protrusion 1126, a fourth protrusion 1127, and a second clearance groove 1128 located between the third protrusion 1126 and the fourth protrusion 1127. The first end of the second bending plate 113 is provided with a third clearance groove 1132 for placing the first protrusion 1123 and the second protrusion 1124 and a fifth protrusion 1131 connected to both sides of the first clearance groove 1125. The second end of the second bending plate 113 is provided with a fourth clearance groove 1134 for placing the third protrusion 1126 and the fourth protrusion 1127 and a sixth protrusion 1133 connected to both sides of the second clearance groove 1128. The first bending plate 112 and the second bending plate 113 surround to form a continuous square frame structure. The panel 111 is used to conveniently connect the skirt on the side, and the skirt is used to weld the frame of the circuit board. The first bending plate 112 and the second bending plate 113 are bent on the panel 111 to form a square frame structure. After bending, the first protrusion 1123 and the second protrusion 1124 at the first end of the first bending plate 112 are bent again towards the direction of the third clearance groove 1132 of the second bending plate 113 until the first protrusion 1123 and the second protrusion 1124 are clamped in the third clearance groove 1132. Further, the third protrusion 1126 and the fourth protrusion 1127 at the second end of the second bending plate 113 are bent towards the direction of the fourth clearance groove 1134 of the second bending plate 113 until the third protrusion 1126 and the protrusion are clamped in the fourth clearance groove 1134. Similarly, the fifth protrusion 1131 at the first end of the second bending is clamped in the first clearance groove 1125 at the first end of the first bending plate 112, and the sixth protrusion 1133 at the second end of the second bending plate 113 is clamped in the second clearance groove 1128 at the second end of the first bending plate 112, so that the first bending plate 112 and the second bending plate 113 form a complete and continuous square frame structure, preventing a gap from appearing between the first bending plate 112 and the second bending plate 113, and effectively improving the shielding effect of the shielding bracket.

[0030] The first bending plate 112, the second bending plate 113, and the panel 111 are integrally formed. The integrally formed shielding frame 11 can increase the hardness of the shielding frame 11 and prevent the first bending plate 112, the second bending plate 113, and the panel 111 from separating.

[0031] A plurality of through holes 1121 with equal spacing are respectively arranged on the first bending plate 112 and the second bending plate 113. The through holes 1121 respectively extend along the length directions of the first bending plate 112 and the second bending plate 113. The through holes 1121 are used to facilitate the clamping of the upper cover 12 and prevent the upper cover 12 from separating from the shielding frame 11. A maintenance opening for maintenance is arranged inside the panel 111. The maintenance opening facilitates the maintenance of the circuit board inside the shielding frame 11. An anti-stagnation plate 1111 and a suction plate 1112 are also arranged inside the panel 111. The anti-stagnation plate 1111 and the suction plate 1112 are arranged diagonally. The anti-stagnation plate 1111 and the suction plate 1112 are used to distinguish the direction in which the circuit board is installed on the shielding frame 11 and play a guiding role. At the same time, the anti-stagnation plate 1111 and the suction plate 1112 are also used to facilitate the suction nozzle to suck the shielding frame 11. A plurality of avoidance grooves 1122 with equal spacing are arranged on the sides of the first bending plate 112 and the second bending plate 113 away from the panel 111. When the circuit board is welded, it is used to avoid non-welding positions, so that the soldering tin flows into the space between the avoidance groove 1122 and the circuit board, thereby ensuring the flatness of the welding surface and effectively improving the welding yield.

[0032] Please refer to Figure 4 , Figure 4 which is a perspective view of the upper cover of the shielding bracket of the present utility model. The shielding bracket is further provided with an upper cover 12 for closing the maintenance opening. A plurality of connecting plates 121 opposite to the skirt edges are arranged on the side edges of the upper cover 12. Clamping protrusions 122 are arranged on the connecting plates 121. The clamping protrusions 122 are all opposite to the skirt edge positions. The connecting plates 121 and the upper cover 12 are integrally formed. The upper cover 12 is used to close the maintenance opening and further enhance the shielding effect of the shielding bracket. The connecting plates 121 are used to fit with the first bending plate 112 and the second bending plate 113, and the clamping protrusions 122 of the connecting plates 121 are clamped in the through holes 1121 or fit with the first bending plate 112 or the second bending plate 113, so that the upper cover 12 is fixed inside the shielding frame 11 and prevents the upper cover 12 from separating from the shielding frame 11.

[0033] Working principle:

[0034] When assembling the shielding bracket, bend the first bending plate 112 and the second bending plate 113 of the stamped shielding frame 11. After the first bending plate 112 and the second bending plate 113 are bent, bend the first protrusion 1123 and the second protrusion 1124 at the first end of the first bending plate 112 towards the third clearance groove 1132 at the first end of the second bending plate 113, and snap the first protrusion 1123 and the second protrusion 1124 into the third clearance groove 1132. Further, snap the third protrusion 1126 and the fourth protrusion 1127 at the second end of the first bending plate 112 into the fourth clearance groove 1134 of the second bending plate 113. Further, snap the fifth protrusion 1131 at the first end of the second bending plate 113 into the first clearance groove 1125 at the first end of the first bending plate 112, and snap the sixth protrusion 1133 at the second end of the second bending plate 113 into the second clearance groove 1128 at the second end of the first bending plate 112, thereby filling the gap between the connections of the first bending plate 112 and the second bending plate 113. Finally, connect the upper cover 12 to the outside of the shielding frame 11. The upper cover 12 closes the maintenance opening. The clamping protrusion 122 of the connecting plate 121 of the upper cover 12 is clamped in the through hole 1121 and on the skirt edge to prevent the upper cover 12 from separating from the shielding frame 11, further improving the shielding effect.

[0035] In the shielding bracket of this preferred embodiment, by snapping the first protrusion and the second protrusion of the first bending plate into the third clearance groove, the third protrusion and the fourth protrusion into the fourth clearance groove, the fifth protrusion into the first clearance groove, and the sixth protrusion into the second clearance groove, the gap between the first bending plate and the second bending plate is sealed, improving the shielding effect.

[0036] In summary, although the present utility model has been disclosed above with the preferred embodiments, the above preferred embodiments are not intended to limit the present utility model. Those of ordinary skill in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the scope defined by the claims.
