Abstract

The invention provides a high-frequency slip ring device. The high-frequency slip ring device comprises a main shaft (1) and a plurality of slip ring portions, wherein the main shaft (1) is made of metal; the multiple slip ring portions are arranged on the main shaft (1) in a sleeved mode, each slip ring portion comprises a signal loop (11) and two shielding loops (12), and the two shielding loops (12) of each slip ring portion are arranged on the two opposite sides of the corresponding signal loop (11). According to the high-frequency slip ring device, the technical problems that in the prior art, electric signals leak between slip rings, and the signal shielding effect is not good are solved.

Description

technical field [0001] The invention relates to the technical field of electric signal transmission, in particular to a high-frequency slip ring device. Background technique [0002] Some antenna radars often use special high-frequency band signals. The high-frequency slip ring device in the prior art has poor signal shielding effect and is easy to leak. Contents of the invention [0003] The present invention aims to provide a high-frequency slip ring device to solve the technical problems of electric signal leakage and poor signal shielding effect in the high-frequency slip ring device in the prior art. [0004] In order to achieve the above object, according to one aspect of the present invention, a high-frequency slip ring device is provided, including: a main shaft, the main shaft is a metal main shaft; a plurality of slip ring parts, and a plurality of slip ring parts are sleeved on the main shaft; each slip ring The ring portion includes a signal ring and two shiel...
