Abstract

The invention relates to the technical field of electronic product manufacturing, and provides a shielding grounding structure and terminal equipment. The shielding grounding structure is used for electrically connecting a printed circuit board and a metal framework and comprises a shielding grounding unit, wherein the shielding grounding unit comprises a shielding cover and an elastic part, the shielding cover and the elastic part are integrally formed, the shielding cover is used for connecting the printed circuit board, and the printed circuit board is electrically connected with the metalframework by the elastic part so that the electrical conduction of the printed circuit and the metal framework is achieved. The shielding cover and the elastic part are integrally formed, thus, the elastic part can be simultaneously formed when the shielding cover is fabricated, the material number is reduced, and the fabrication cost is favorably reduced; and since the printed circuit board is electrically connected with the metal framework by the elastic part, the printed circuit board is prevented from being directly extruded during the connection process, so that no damage to the printed circuit board is generated.

Description

technical field [0001] The present application relates to the technical field of electronic product manufacturing, and more specifically, relates to a shielding grounding structure and terminal equipment. Background technique [0002] As an important electronic component, PCB (Printed circuit board) is a support for electronic components and a carrier for electrical connections. Electronic components play specific functions after being installed on the PCB, such as computer motherboards, terminals Equipment circuit boards and signal transmitting and receiving circuit boards, etc. The PCB board installed with electronic components functions as an overall structure, but it essentially includes a plurality of different signal units, and each signal unit is installed in a different area of ​​the PCB board and performs different functions. [0003] When the PCB board is used in mobile devices, in order to ensure good work, the PCB board needs to be grounded in contact with the m...
