How to design the box body of the mobile phone shielding box

Author:admin   AddTime:2021-03-09

The mobile phone shielding box adopts various shapes of shielding bodies such as shells, plates, sleeves made of conductive or magnetic conductive materials, which can limit the electromagnetic ability within a certain space range, and is used to suppress the metal body of radiation interference. Therefore, the mobile phone shielding box is A device that puts the wireless communication device under test in a non-interference test environment.

The box design of the mobile phone shielding box should ensure the continuity of its conductivity, and ensure the surface finish and contact tightness of the product. At present, there are many modes used in the market: die-casting, casting, sheet metal welding, etc. The die-casting box can better ensure the closeness of the material molecule contact, ensure better electrical continuity, and the casting can also be well isolated after the surface treatment. Although the surface treatment process is omitted in sheet metal welding, it is easy to cause the isolation degree to be reduced in the welding contact surface. The processing requirements of the butt joint surface are relatively high. Poor processing will affect the isolation and service life of the mobile phone shielding box. In addition, mobile phone shielding The box design of the box should also pay attention to grounding.



There is also conduction. Conduction is a key part of the mobile phone shielding box. When the product is placed in the mobile phone shielding box, it must communicate with the outside world through the interface when testing. It needs to be connected to the test instrument. If the interface filtering is not good, connect the RF line of the instrument. It will become an antenna and lead the signal into the mobile phone shielding box, there will be no shielding effect, and the isolation will be extremely reduced. The test also cannot feedback accurate data. Therefore, the key to the isolation of the mobile phone shielding box needs to be grasped on the interface processing, and the interface filtering methods are different for different tested product frequencies.

The mobile phone shielding box adopts advanced casting technology, filtering and automatic control technology to make the performance more standard. It can effectively realize the communication with the computer and incorporate its standard instructions into the test program; it has multiple safety protections during operation. Function, can effectively prevent misoperation from causing damage to the operator and the product.
