Description

Technical Field

[0001] This utility model relates to the field of electronic shielding technology, and in particular to a shielding frame and electronic equipment. Background Technology

[0002] When designing various electronic devices, it is often necessary to take measures to prevent mutual interference between components and the influence of external electromagnetic signals on the components. Components are often protected by shielding covers, and shielding frames provide the mounting base for the shielding covers.

[0003] The inventors of this invention discovered that current shielding frames are formed by bending the edges of a sheet of material downwards. The bent portion forms the side panels, while the unbent portion forms the top panel. The shielding frame includes a drop corner, and a connecting rod is provided between the drop corner and the sheet material to ensure the shielding frame is integral with the sheet material before dropping. Currently, during the dropping process, the shielding frame is separated from the sheet material by cutting the connection between the connecting rod and the drop corner. This method creates a gap between the side panels on both sides of the drop corner, reducing the shielding effect. Utility Model Content

[0037] It is understandable that the shielding frame 100 can be formed by stamping the sheet metal using a stamping machine, causing the shielding frame 100 to detach from the sheet metal. The sheet metal is made of electromagnetic shielding material, which can be metals such as glass copper or stainless steel. Before blanking, the shielding frame 100 and the sheet metal are a single unit. The top plate 1, the baffle 3, the first side plate 2, the second side plate 4, the third side plate 5, and the sheet metal are located on the same plane. The baffle 3 between the blanking angle and the sheet metal connects the shielding frame 100 and the sheet metal into a single unit. After bending the first side plate 2, the second side plate 4, and the third side plate 5 to be perpendicular to the top plate 1, the second side plate 4 and the third side plate 5 are joined together, improving the shielding performance of the shielding frame 100. Finally, the connection between the baffle 3 and the sheet metal is cut off, and the baffle 3 is bent until it is located in the first gap. The baffle 3 prevents a gap from forming between the two first side plates 2, thus improving the shielding performance of the shielding frame 100.

[0038] In some embodiments, please refer to Figure 3 and Figure 4 , and then combine Figure 2 There are two second parts 12, which are respectively located at both ends of the third part 13. One end of the second part 12 is located in the third part 13, and the other end of the second part 12 is located at the end of the first part 11 away from the baffle 3. There are two second side plates 4, one of which is located in the second part 12.

[0039] In this embodiment of the utility model, the shielding frame 100 includes a top plate 1, first side plates 2, and a baffle 3. The shielding frame 100 includes a top plate 1, a baffle 3, and two first side plates 2; the top plate 1 includes two first portions 11 connected at an included angle, forming a material drop angle at the connection point; two first side plates 2 are provided, one first side plate 2 connected to one first portion 11, the first side plate 2 and the first portion 11 are integrally formed, and a first gap is spaced between the two first side plates 2; one end of the baffle 3 is connected to the material drop angle, and the baffle 3 is integrally formed with the top plate 1, the other end of the baffle 3 extends along the first gap. Before material drop, the shielding frame 100 and the plate are a single unit. The top plate 1, the baffle 3, the first side plates 2, and the plate are located on the same plane, and the baffle 3 between the material drop angle and the plate connects the shielding frame 100 and the plate into a single unit. After bending the two first side plates 2 to be perpendicular to the top plate 1, cut off the connection between the baffle strip 3 and the plate, and bend the baffle strip 3 until it is located in the first gap. The baffle strip 3 prevents the formation of a gap between the two first side plates 2, thus improving the shielding performance of the shielding frame 100.
