They are used as connectors for rotating structures in numerous applications requiring rapid signal transmission. However, conductive slip rings are still required for transmitting electrical signals and power. Therefore, optoelectronic hybrid slip rings, which can transmit both optical and electrical signals, combine these capabilities and play a vital role in modern systems.

[0005] However, when the existing optoelectronic hybrid slip ring is in use, when tension occurs at both ends, it will cause an offset between the stator and the rotor of the optoelectronic hybrid slip ring, resulting in a decrease in the stability of signal transmission. Utility Model Content

[0011] Preferably, the fixing member includes a plurality of positioning rods which are movably arranged on the end surface of the connecting ring away from the rotating ring and one end of which can be movably arranged on the bottom wall of the connecting groove away from the groove, and a control structure which is arranged on the connecting ring and controls the plurality of positioning rods to pass through the connecting groove.

[0012] Preferably, the control structure includes a positioning ring parallel to the end face of the connecting ring and one end face of which is fixedly connected to multiple positioning rods away from one end of the connecting ring, and multiple fixing screws that are movable through the connecting ring and whose ends can be threadedly connected to the end face of the connecting ring.

[0013] Preferably, a sealing groove with an annular structure is opened on the wall of the rotating groove, and a sealing ring is arranged in the sealing groove.

However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0024] like Figure 1-4 As shown, the rotor body 2 is sleeved on the end face of the stator body 1 through the rotation groove 6 provided. At this time, the end face of the connecting ring 4 is fitted with the end face of the rotating ring 3. In the process of fitting the end faces of the rotating ring 3 and the connecting ring 4, a plurality of connecting rods 9 provided on the end face of the rotating ring 3 are controlled to pass through the connection groove 10 provided on the end face of the connecting ring 4, and the positions of the plurality of connecting rods 9 in the connection groove 10 are fixed by a fixing assembly. The rotating ring 3 is rotatably provided on the side face of the stator body 1. When the stator body 1 and the rotor body 2 rotate, the stable rotation between the stator body 1 and the rotor body 2 is ensured. When tension occurs between the stator body 1 and the rotor body 2, the connection between the stator body 1 and the rotor body 2 through the connecting ring 4 and the rotating ring 3 is avoided. This ensures the stability of the rotational connection between the rotor body 2 and the stator body 1, improves the tensile strength of the optoelectronic hybrid slip ring, and ensures the stability of the signal transmission of the optoelectronic hybrid slip ring.

[0025] The inner ring surface of the rotating ring 3 is rotatably connected to the side surface of the stator body 1 through a rotating shaft.

[0026] The rotating ring 3 is rotatably connected to the stator body 1 via the rotating shaft, thereby ensuring the stability of the rotational connection between the rotor body 2 and the stator body 1 .

[0028] like Figure 2-4 As shown, when the stator body 1 and the rotor body 2 are rotatably connected and installed, the rotating groove 6 opened on the rotor body 2 is sleeved on the end face of the stator body 1. At this time, the end face of the connecting ring 4 set on the end face of the rotor body 2 is fitted with the end face of the rotating ring 3, and the multiple connecting rods 9 set on the end face of the rotating ring 3 are controlled to pass through the connecting groove 10 opened on the end face of the connecting ring 4, and the rotating ring 3 is rotated so that the protrusions set on the multiple connecting rods 9 pass through the grooves opened on the connecting groove 10, and the position of the connecting rods 9 in the connecting groove 10 is fixed with the fixing piece, thereby ensuring the stability of the connection between the rotating ring 3 and the connecting ring 4.

[0029] The fixing part includes a plurality of positioning rods 11 which are movably arranged on the end surface of the connecting ring 4 away from the rotating ring 3 and one end of which can be movably arranged on the bottom wall of the connecting groove 10 away from the groove, and a control structure which is arranged on the connecting ring 4 and controls the plurality of positioning rods 11 to pass through the connecting groove 10.

[0030] The control structure includes a positioning ring 5 which is parallel to the end face of the connecting ring 4 and one end face of which is fixedly connected to a plurality of positioning rods 11 away from one end of the connecting ring 4, and a plurality of fixing screws 12 which are movable through the connecting ring 4 and the ends of which can be threadedly connected to the end face of the connecting ring 4.

[0031] like Figure 1-4As shown, when the end faces of the rotating ring 3 and the connecting ring 4 are fitted together, and the protrusion provided on the end face of the connecting rod 9 is controlled to pass through the groove, the fixing screw 12 is rotated. At this time, the fixing screw 12 is passed through the connecting ring 4 through a threaded connection, and drives the positioning ring 5 to move in the direction of the connecting ring 4, which can drive multiple positioning rods 11 provided on the end face of the positioning ring 5 to pass through the connecting groove 10. At this time, after the positioning rod 11 is passed through the connecting groove 10, the protrusion provided on the connecting rod 9 is passed through the groove, and the position of the positioning rod 11 in the connecting groove 10 can be fixed, ensuring stable rotation installation between the rotor body 2 and the stator body 1, improving the tensile strength of the optoelectronic hybrid slip ring, and ensuring the stability of signal transmission of the optoelectronic hybrid slip ring.

[0032] A sealing groove 7 with an annular structure is provided on the wall of the rotating groove 6 , and a sealing ring 8 is provided in the sealing groove 7 .
