Abstract
Description
technical field
[0001] The invention relates to the field of electronic equipment structure design, in particular to a thin-walled electromagnetic shielding door. Background technique
[0002] With the rapid development of electronic technology, a large number of modern communication products have emerged in the market. However, due to the wide application of electronic frequency domain ranging from low frequency to high frequency and even ultra high frequency, it is easy to generate electromagnetic interference between electronic devices. When we design products, we must pay attention to the environmental interoperability between electronic devices-that is, the electromagnetic compatibility (EMC) of electronic devices. The shell of electronic equipment is generally made of thin-walled metal processing to form a closed case and its panel. The case is a good shield, but due to the display interface, operation switches and buttons, external interfaces, ventilation and heat di...
Examples
Embodiment
[0032] Such as figure 1 As shown in A, the traditional electromagnetic shielding chassis will form a lot of holes, gaps or windows (we call these holes, Gaps or windows are electromagnetic field leakage parts), which will damage the shield of the chassis, which will inevitably bring electromagnetic leakage and interference.
[0033] In order to realize electromagnetic protection, the present invention shields the electromagnetic field leakage of the electronic equipment casing (such as the case, the case is used as an example below), so an electromagnetic shielding door is set on the aluminum panel at the front of the case 6, and its structure is as follows figure 2 As shown, it includes a door panel 1, a cushion block 2, a fixed block 3, a shaft pin 4, a locking member 5 and a conductive gasket 7. A mounting groove 61 is provided beside the electromagnetic field leakage part A for mounting and fixing the door panel. The spacer 2 is fixed on the inner wall of the cabinet 6 ...
