Abstract

The invention discloses a shielding box. The shielding box comprises a bottom board and side boards, wherein two adjacent side boards are respectively marked as a side board A and a side board B, one side of the side board A, which is connected with the side board B, is provided with a bending part in an extension way, and the bending part is lapped on the outer side surface of the side board B. The shielding box provided by the invention has the advantages that the connection between the two adjacent side boards is realized through a lapping structure of the bending part, a welding technical process is omitted, and the manufacturing time and the manufacturing cost of the shielding box are reduced.

Description

technical field [0001] The invention relates to a shielding box structure, in particular to a shielding box used in household appliances and manufactured only by cutting and bending metal plate processes. Background technique [0002] In order to prevent the interference of high-frequency electromagnetic fields on the circuit, anti-electromagnetic interference is an important part of the structural design of high-frequency circuits. The existing method is to install the circuit that generates high-frequency signals or the circuit that works in the high-frequency electromagnetic field environment in a metal shielding box. middle. In the existing shielding box, after cutting and bending the metal plate, welding is used to complete the contact between the sides. The increase of the welding process will undoubtedly increase the manufacturing time and cost of the shielding box. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies i...
