Description

Technical Field

[0001] The utility model belongs to the technical field of VR equipment, and in particular relates to a 90° slip ring suitable for VR equipment. Background Art

[0002] Slip rings are used in the process of product equipment rotation and can still provide various signals and power. With the gradual miniaturization of modern equipment, VR and camera equipment need to rotate 360 ​​degrees during use. During rotation, it is necessary to ensure that the product signal power is not affected, which greatly limits the rotation space of the slip ring. Since the conductive slip ring can withstand hundreds to thousands of revolutions per minute, these VR devices need to ensure that the slip ring can transmit high-definition video during operation while providing multiple stimulations such as vision, touch, and hearing, and do not interfere with USB signals, so that users can turn 360 degrees without restriction when using VR equipment, and the visual effect will not be affected, thereby greatly improving the user experience.

[0003] When the current slip ring is in use, the output wire of the slip ring will interfere with the equipment, and the wire needs to be bent manually. Double-wall heat shrink tubing is also used to heat shrink the wire to increase the strength of the wire. However, this will greatly increase the bending radius of the wire and take up more space. At the same time, the traditional slip ring rotor and stator are one-to-one transmission, resulting in poor versatility of the stator side signal interface. Utility Model Content

[0029] The present application provides a 90° slip ring suitable for VR equipment. By bending the rotor conductor 13 through the wire sheath 14, the structure can be more reliable, the disassembly is simpler, and the cost is lower. The bending structure adopted can greatly reduce the length of the outgoing wire on the rotor side, and can ensure normal operation in a relatively small space.
