Electromagnetic interference shielding structure and its operation method

Abstract

The invention discloses a shielding structure for shielding electromagnetic interference from inner modules of electronic equipment including the interface slot, heat dissipation device and metal connector. The interface slot is installed on the electronic equipment, in which, a bus is used to combine the electronic equipment with the inner module, and a fixed component linking with grounding loop of the electrical equipment is used to fix the inner module to the interface slot. The heat dissipation device is installed on the inner module. One end of the metal connector is fixed on the inner module to lock into the fixed component, and the other end is contacted with the heat dissipation device.

Description

technical field [0001] The invention relates to a shielding structure for improving electromagnetic interference of electronic equipment and an application method thereof, in particular to an electromagnetic interference shielding structure for improving built-in modules of electronic equipment and an application method thereof. Background technique [0002] With the advancement of electronic technology and the increasing popularity of electronic industry applications, the design of electronic products is usually required to be light and thin, and the hardware design and software and hardware update cycles are increasingly shortened. In order to make electronic products, such as notebook computers, portable TVs, mobile Telephones, video recorders, personal digital assistants (Personal Digital Assistant, PDA), and digital cameras are easy to assemble to reduce production costs, and at the same time take into account subsequent software and hardware updates and upgrades, often ...

[0006] However, an additional metal plate is installed between the motherboard and the built-in module, which not only increases the weight of the product, takes up wiring space, but also increases the manufacturing cost. In addition, the use of pigtails or the electrical connection method of directly contacting the metal plate with the ground loop, The effect of electrical contact is not easy to grasp, and it is easy to fail due to collision during handling or carrying
