Description

Shielding cover easy to assemble

Technical Field

The utility model relates to the technical field of shielding cases, in particular to an easy-to-assemble shielding case.

Background

The shielding case is used as a basic device of EMC (electromagnetic compatibility, meaning the capability of electromagnetic energy generated by equipment not to interfere with other equipment or not to interfere with electromagnetic energy of other equipment), and is widely used in the fields of military industry, medical treatment, industrial control, electronics, and the like.

At present, in the electronic industry, a metal copper foil is attached or a single-layer shielding cover with a metal structure is used to achieve the purpose of shielding a corresponding area on equipment; however, in the case of attaching a metal copper foil or using a single-layer shield case of a metal structure, the upper shield layer needs to be removed for maintenance during equipment maintenance and inspection, and the operation is complicated and inconvenient, and the maintenance and inspection efficiency is low.

Disclosure of Invention

In order to overcome the defects in the prior art, the utility model discloses a shielding cover which is easy to assemble.

In order to achieve the above purpose, the present utility model is realized by the following technical scheme: the utility model provides a shield cover of easily assembling, includes the shield cover support that is used for with the circuit board is fixed and with shield cover support demountable installation's shield cover body, the upper edge down shaping several is fluted around the shield cover support, all is provided with the elastic clamp that presss from both sides mouthful up in the several recess, be provided with several shielding on the periphery of shield cover body and found the wall, the bottom protrusion of several shielding found the wall is provided with the fixture block, when shield cover body and shield cover support installation, the fixture block joint is in the elastic clamp.

Further, several shielding risers are interconnected and/or not interconnected.

Further, the elastic clamp is arranged in a shape of being narrow at the upper part and wide at the lower part, ribs are arranged on the inner walls of the two sides of the elastic clamp, and positioning grooves are formed in the two sides of the clamping block, which are clamped with the elastic clamp, of the clamping block.

Further, the height of the clamping block is consistent with the depth of the groove.

Further, the shielding cover bracket is fixed with the circuit board by adopting a welding process.

Further, the shielding cover bracket and the shielding cover body are of a square structure which is matched with each other.

Further, the upper surface of the shielding cover body is provided with a plurality of monitoring windows and a plurality of heat dissipation holes.

The utility model has the following beneficial effects:

the utility model can enable the shielding cover body to be quickly installed with the shielding cover bracket through the mutual matching of the clamping blocks and the elastic clamps, and compared with the method for directly fixing the shielding cover body on the circuit board, the utility model can facilitate the quick disassembly and assembly of operators, reduce the overhaul time of the operators on the electric elements in the circuit board and has high use value.
