Abstract

The invention relates to a cable shielding device, comprising: a shielding sleeve made of copper cloth, used for sleeving on a cable and provided with a connection part for connecting with a ground wire; a first heat shrinkable film for wrapping around the shielding sleeve. The invention also relates to a cable connection with an electromagnetic shielding function. By means of the cable shieldingdevice or cable connection according to the invention, electromagnetic leakage between the cable and the connector can be significantly reduced, thereby realizing efficient electromagnetic shielding,and the cable connection can prevent burrs at the end of the shielding sleeve from puncturing a conductor insulation layer, while reducing the weight and mounting space of the shielding device.

Description

technical field [0001] The present invention relates generally to satellite cable signal transmission, and in particular to a cable shielding device. In addition, the invention also relates to a cable connection with electromagnetic shielding function. Background technique [0002] The electromagnetic compatibility design of spacecraft plays an extremely important role in the model development, because its electronic equipment will generate more or less electromagnetic interference energy, and these electromagnetic interference energy may cause adverse effects on surrounding sensitive electronic equipment. [0003] At present, the main purpose of the solution is to add a wave-proof sleeve to the signal cable that is susceptible to interference for shielding. Anti-wave casing materials are mostly tinned copper wire, aluminum-magnesium alloy wire, and the specifications are generally [0004] 24*8 / 0.15mm, the weaving density is 75% to 85%. [0005] The main grounding method...
