[0004] However, considering the processing technology of this snap-in shielding structure, 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, such as figure 2 The schematic diagram of the full clip-on shielding structure in the box-type cabinet shown will cause the 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 cabinet.
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

Embodiment Construction
[0013] The embodiments of the present invention provide a shielding structure that does not block the ventilation holes of the box, thereby improving the heat dissipation performance of the box.
[0014] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0015] See first image 3 , image 3 It shows a schematic diagram of a three-dimensional structure of a shielding structure according to an embodiment of the present invention, including a first housing 302 and a second housing 303. The first housing is provided with a plurality of ventilation holes to form a ventilation area 201 for realizing internal and external ventilation. , to achieve the effect of heat dissipation; the part outside the ventilation area 201 is a non-ventilation area. The edge portions of the first housing 302 and the second housing 303 are overlapped, and an assembly component is provided at the overlapping portion to assemble the fir...

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 thefirst 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 the schematic diagram of the existing snap-in shielding structure. Inside the box-type box, the side of the second shell of the box is connected to the The card boards 102 are snapped together. The clamping type shielding structure has reliable overlapping of components, and the shielding effect can reach 15-20dB / 1GHz, and its material cost is also very...
