Abstract

The invention provides an electromagnetic shielding method of satellite cables. The method includes the steps that first, electromagnetic wave shielding fabric and a bonding material are tested; numbers of the cables in which shielding processing is needed and a number of an electric coupler are recorded; the electromagnetic wave shielding fabric is tailored according to different cables, and the bonding material is bonded on the edge of the electromagnetic wave shielding fabric; the electromagnetic wave shielding fabric is bonded on a bunch of cables, so that a cable segment shielding layer is formed; the electromagnetic wave shielding fabric and Teflon thin films are manufactured into an electric coupler template according to the size of the electric coupler; the electric coupler template is wound outside the electric coupler to form an electric coupler shielding outer layer; the electromagnetic wave shielding fabric coating the electric coupler is erected on the outer layer of the bunch of cables; the Teflon thin films are wound outside the electric coupler coated with the electromagnetic wave shielding fabric and outside the bunch of cables, and the cable assembly after being coated is tested. The electromagnetic shielding method of the satellite cables has the advantages of effectively lowering the weight of satellite borne cables, and improving the EMI performance and reliability of the satellite cables.

Description

technical field [0001] The invention relates to the technical field of secondary electromagnetic shielding of satellite onboard components, in particular to an electromagnetic shielding method for satellite onboard cables. Background technique [0002] The electromagnetic environment in the satellite is complex, the number of satellite-borne cables is large, and the interfaces are diverse, which leads to the effect of electromagnetic shielding during the satellite ground test and on-orbit operation directly affecting the electromagnetic compatibility index of the entire satellite, which has become an important part of the electromagnetic compatibility design of the entire satellite. Cable secondary electromagnetic shielding is a method of using the shielding properties of materials to construct a shielding mechanism outside the formed on-board cable. Due to the compact space on the satellite, strict quality control of the product on the satellite, and a large number of stand...
