Problems solved by technology

If the cable length setting is unreasonable, it will cause the cable resistance torque to be too large during the deployment process, resulting in the failure of the antenna deployment
Improper cable routing during the unfolding process will cause a large torque on the cable, causing the cable head to loosen, affecting the quality of signal transmission and even causing channel interruption

Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0019] figure 1 As shown, in the U-shaped wiring method provided by the present invention, the deformed section 1 of the radio frequency cable is U-shaped before deployment. figure 2 As shown, the deformed section 1 of the radio frequency cable is arc-shaped after deployment, and the deployment angle is 110 degrees. During the rotation of the high-frequency cable, the deformation is smooth and the resistance moment is small. The diameter of the RF cable in this example is 5mm, and the unfolding torque...

Abstract

The invention provides an optimal wiring method conforming to rotation demand of an outboard radio frequency cable. The radio frequency cable comprises a deformation segment and a movable segment, wherein the deformation segment of the radio frequency cable is in a U shape before being unfolded and is in an arc shape after being unfolded, and an unfolded angle of the cable is not larger than 120 degrees. The high-frequency cable is smooth in deformation and small in resistant moment during the rotation process, the radio frequency is not twisted and deformed during the unfolding process, and aplug-pin piece of the radio frequency cable is prevented from lossening to cause a fault. The high-frequency cable is smooth in deformation and small in resistant moment during the rotation process,and the reliability of a product during the rotation process is improved.

Description

technical field [0001] The invention relates to a cable wiring method outside the cabin of a space-borne antenna, more specifically, an optimized wiring method that meets the rotation requirement of the radio frequency cable outside the cabin. Background technique [0002] The spaceborne deployment antenna requires the matching radio frequency cable to participate in the deployment process when performing the deployment action. Improper routing of RF cables can cause a series of unreliable factors. If the cable length is set unreasonably, the resistance torque of the cable will be too large during the deployment process, resulting in the failure of the antenna deployment. Improper cable routing during the unfolding process will cause the cable to generate a large torque, causing the cable head to loosen, affecting the quality of signal transmission and even causing channel interruption. Contents of the invention [0003] In view of the defects in the above-mentioned prio...
