Problems solved by technology

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 shielding body, but due to the display interface, operation switches and buttons, external interfaces, ventilation and heat dissipation, processing and installation, etc. must be set up a lot Holes, gaps or windows, thus destroying the shielding body of the chassis, this will inevitably bring electromagnetic leakage and interference, so we must take corresponding protective measures during design

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 ...

Abstract

The invention provides a thin-walled electromagnetic shielding door, which is used to shield the electromagnetic field leakage of the housing of electronic equipment. A mounting slot is opened next to it, and the spacer is fixed on the inner wall of the electronic device housing by screws, and the fixing block is connected and fixed through the mounting slot with the spacer, and one side of the door panel is rotated by the pivot pin and the fixing block connected, the other side of the door panel is locked and connected with the housing of the electronic device through the locking member, and the conductive gasket is pasted around the inner surface of the door panel. The whole combination part of the present invention is compact, easy to process and assemble, can well shield the electromagnetic field leakage part of the equipment, and ensure that the equipment is well anti-leakage and anti-interference to electromagnetic signals.

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...
