Problems solved by technology
[0003] The compartments of the existing shielding structure are usually manufactured by stamping and forming of thin sheet metal parts. Since the compartments are cut from a whole piece of thin sheet metal with a knife die and then bent, the side edges need more space due to the flattening and bending of the sheet metal. Leave enough gap between the die and die, resulting in a large gap
In addition, limited by the manufacturing process of sheet metal flattening and bending, the existing shielding structure compartment can only be used by a single model, and only one type of compartment will be fixed, resulting in a low degree of freedom, and the compartment cannot be flexibly adjusted according to the circuit layout. position

The invention discloses a shielding structure, applicable to being arranged on one circuit board, and comprising a main beam, a strut beam and a mask. The main beam is fixedly arranged on the circuitboard, the main beam comprises a main beam body and a main beam connecting unit, and the main beam connecting unit is arranged on the main beam body. The strut beam comprises a strut beam body and a strut beam connecting unit, the strut beam connecting unit is arranged on the strut beam body, the strut beam connecting unit is connected with the main beam connecting unit, and the main beam connecting unit is partially located between the strut beam connecting unit and the circuit board. The mask is provided with a cover pat and a surrounding wall extended and buckled from the cover part, and the mask covers the main beam and the strut beam and is connected with the circuit board by virtue of the surrounding wall.
Description
technical field [0001] The present invention relates to a shielding structure, in particular to a shielding structure with high design freedom. Background technique [0002] The shielding structure is a mechanism part that is widely used in various electronic products to shield electromagnetic signals and reduce interference. [0003] The compartments of the existing shielding structure are usually manufactured by stamping and forming of thin sheet metal parts. Since the compartments are cut from a whole piece of thin sheet metal with a knife die and then bent, the side edges need more space due to the flattening and bending of the sheet metal. Leave enough die clearance, resulting in a large gap. In addition, limited by the manufacturing process of sheet metal flattening and bending, the existing shielding structure compartment can only be used by a single model, and only one type of compartment will be fixed, resulting in a low degree of freedom, and the compartment canno...
