Description

Technical Field

[0001] The present invention relates to the technical field related to communication equipment, and in particular to a slip ring for radio frequency transmission. Background Art

[0002] In the field of communications, especially in facilities such as base stations and satellite communication ground stations that require rotating antennas, RF transmission slip rings play a key role. They can ensure that the antenna can continuously and stably receive and send RF signals during rotation, achieving all-round communication coverage. In some large mobile communication base stations, the antenna needs to constantly adjust its direction to optimize the signal coverage. The RF transmission slip ring can ensure uninterrupted signal transmission when the antenna rotates, thereby improving communication quality and stability. Therefore, we need a slip ring for RF transmission.

[0003] However, the slip rings currently used for radio frequency transmission cannot provide continuous resistance to contact parts, cannot remove oxidation from the surface of oxidized parts, and cannot quickly replace device parts. Summary of the invention

[0004] The object of the present invention is to provide a slip ring for radio frequency transmission to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A slip ring for radio frequency transmission comprises a stator sleeve, the outer wall of the stator sleeve is installed with a conductive ring, the inner wall of the conductive ring is electrically connected to a radio frequency transmission line, the outer wall of the conductive ring is in contact with a brush, one end of the brush is welded to a transmission slip ring, the inner wall of the transmission slip ring is welded with a spring sheet, one side of the spring sheet is provided with an oxidation brush, the inner wall of the transmission slip ring is fixedly connected with an adjustment rod, one end of the adjustment rod is in contact with a spring, both sides of the transmission slip ring are in contact with a pad, one side of the pad is in contact with a rubber ring, the outer wall of the rubber ring is in contact with a fixing ring, and the outer wall of the fixing ring is fixedly connected to a movable sleeve.

[0007] Preferably, the stator sleeve is snap-fitted to the conductive rings, and the conductive rings are arranged at equal intervals on the outer wall of the stator sleeve.

[0008] Preferably, the outer wall of the conductive ring is tightly fitted with the outer wall of the brush, and the brush is symmetrically arranged with respect to the central axis of the conductive ring.

[0009] Preferably, the transmission slip ring is threadedly connected to the adjusting rod, and the outer wall of the adjusting rod is threaded.

[0010] Preferably, the adjusting rod is engaged with the spring, and the inner wall diameter of the adjusting rod is larger than the outer wall diameter of the spring.

[0011] Preferably, the outer wall of the pad is tightly fitted with the outer wall of the transmission slip ring, and the pad is arranged parallel to the transmission slip ring.

[0012] Preferably, the fixing ring is threadedly connected to the rotor sleeve, and the outer wall of the fixing ring is threaded.

[0013] Preferably, the washers are movably connected to the rotor sleeve, and the washers are arranged at equal intervals on the inner wall of the rotor sleeve.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. A fixing ring is used to thread the rotor sleeve. When the device is in use, the setting of the fixing ring and the rotor sleeve can quickly replace the transmission slip ring. The transmission slip ring plays a threaded fixing role on the adjustment rod. When the device is in use, the setting of the transmission slip ring and the adjustment rod can continuously resist the brush. At the same time, the transmission slip ring connects the oxidation brush. When the rotor sleeve rotates, it drives the oxidation brush to remove the oxide on the surface of the conductive ring, and continuously keeps the conductive ring in contact with the brush.
