Description

Technical Field

[0001] This invention relates to the field of slip rings, and more particularly to a radio frequency optoelectronic integrated slip ring. Background Technology

[0002] Slip rings are classified according to their working principle into smooth slip rings, electric slip rings, and radio frequency slip rings. Slip rings are used in systems that require relative rotation to transmit signals and current. Because they need to rotate 360° without restriction to send and receive signals, a slip ring needs to be installed at the center of rotation to ensure the smooth and uninterrupted transmission of radio frequency coaxial signals and current during rotation. They have wide applications in military, industrial, and commercial fields, such as mobile communication, radar, high-definition cameras, and video surveillance.

[0003] Currently, the integration of RF slip rings on the market is poor. Generally, a slip ring can only transmit one type of signal and cannot transmit RF and optical signals simultaneously. When transmitting optical and electrical signals, multiple slip rings are required. In some environments with limited space, they cannot be installed at the same time, which urgently needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to design an integrated radio frequency optoelectronic slip ring to solve the above problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] A radio frequency optoelectronic integrated slip ring, comprising:

[0007] Rotor housing;

[0008] The stator housing; both the rotor housing and the stator housing are provided with mounting cavities;

[0009] Mounting assembly; the rotor housing and stator housing are rotatably connected by the mounting assembly, and the central axis of the stator housing and the central axis of the rotor housing are on the same straight line;

[0010] Radio frequency (RF) components for transmitting RF signals; the input and output terminals of the RF components are respectively installed in the mounting cavities of the rotor housing and the stator housing, and the central axes of the input and output terminals of the RF components are parallel to the central axis of the stator housing.

[0011] An optical component for transmitting optical signals; the input and output ends of the optical component are respectively installed in the mounting cavities of the rotor housing and the stator housing, and the central axes of the input and output ends of the optical component are on the same straight line as the central axis of the stator housing.

[0012] The beneficial effects of this invention are as follows: by installing the input and output ends of the radio frequency component and the input and output ends of the optical component separately in the mounting cavity of the rotor housing and the stator housing, the transmission of optical signals can be achieved simultaneously with the transmission of radio frequency signals; compared with the traditional technical solution, this application only requires a rotatable structure to realize the transmission of radio frequency components and optical components, which greatly reduces the size of this integrated radio frequency and optoelectronic slip ring and reduces the space occupied by the installation.
