Shielding structure and communication apparatus

Abstract

The invention discloses a shield structure that comprises the first shell and the second shell, said first shell possesses airways to form several aeration areas, assembly parts are set on edge of the first shell and the second shell outside of non aeration area, said assembly parts join the first shell and the second shell. The invention also disclose a communication shield equipment that comprises shield structure equipped on communication equipment, said shield structure includes the first shell and the second shell, said first shell possesses airways to form several aeration areas, assembly parts are set on edge of the first shell and the second shell outside of non aeration area, said assembly parts join the first shell and the second shell. With the invention, airways can not be warded, so radiating performance can be increased.

Description

technical field [0001] The invention relates to the technical field of electronic communication, in particular to a shielding structure of communication electronic equipment. Background technique [0002] In electronic products, it is often necessary to perform electromagnetic shielding on a certain part of the circuit. In the prior art, with the wide application of box-type shielding structures, the shielding effect of the product, the heat dissipation of the whole machine, the processing cost, processing technology, assembly technology, etc. Quality indicators are becoming more and more important. [0003] Figure 1 shows a schematic diagram of the existing snap-in shielding structure. Inside the box-type box, the second shell side of the box is connected to the box through the slot 103 provided on the side 101 of the first shell of the box The clamping plates 102 at the sides are clamped together. The clamping type shielding structure has reliable overlapping of componen...

Problems solved by technology

[0004] However, this snap-in shielding structure, considering the processing technology, the depth H1 of the snap-in structure is 5mm to 10mm, so the flange value H2 of the snap-in slot cannot be made small, as shown in Figure 2. The schematic diagram of the connected shielding structure will cause the card slot 103 to block a part of the ventilation holes in the ventilation area 201 in the longitudinal direction. The shielding structure designed in this way blocks some of the ventilation holes and will affect the heat dissipation of the box.

Considering between the snap-in shielding structures, when the distance L3 between adjacent snap-in shielding structures is greater than 15mm, the shielding effectiveness will be greatly reduced, and the lateral dimension of the fan ventilation area 201 is far more than 15mm, so no matter whether two snap-in shielding structures When the shielding structure moves its position on the shell, its lateral direction will block a part of the ventilation holes in the ventilation area 201, thereby reducing the heat dissipation performance of the ventilation holes
