Description

technical field

The invention relates to a method for forming a cable bundle of a two-dimensional rotating mechanism, which belongs to the technical field of high-frequency signal transmission.

Background technique

The high-frequency signal transmission in the traditional two-dimensional rotating mechanism often uses components such as rotary joints, which may easily cause high-frequency signal loss. On the other hand, when using high-frequency signal lines, due to unreasonable wiring, problems such as interference between the signal line and the rotating mechanism, wear and tear, and short service life often occur. The invention adopts the flexible forming method of the cable bundle, and under the condition of discontinuous rotation of the rotating mechanism, it can replace the electrical connection of traditional two-dimensional mechanisms such as rotating joints and slip rings, so as to realize the lossless transmission of high-frequency signals.

1) Position cable A in the center;

2) Wrap cable B around cable A to obtain a cable bundle;

3) bundling the cable bundle obtained in step 2) into sections;

Above-mentioned steps 1) and the diameter of cable A in step 2) are greater than the diameter of cable B, and the rigidity of cable A is greater than the rigidity of cable B;

The cable bundle in the above step 3) can pass through the hollow rotating shaft, and can be formed at a predetermined angle between the cable bundles at both ends of the hollow rotating shaft, and the angle between the cable bundles at both ends can be rotated within the range of 180° ;
