摘要： In a slip ring 100, differential signal slip rings 70 are formed using a base substrate 30 where an electrode pattern and a relative permittivity are optimized to transmit a signal by using one differential signal slip ring 70 to one differential signal cable 60a. Consequently, a low voltage differential signal of 0.35V adopted in video signals of 4K resolution can be transmitted while the camera is continuously rotated through 360 degrees.

摘要： A rotary electronic component capable of reducing an abrasion and a metal fatigue of a slider and extending a rotation life time compared to the conventional technology. A rotary electronic component is provided with a buffer member between a sliding portion of a slider and a rotor. Thus, the sliding portion is energized toward the annular electrode with a proper elastic force and the sliding portion is held. Because of this, vibration of the sliding portion is suppressed and metal fatigue of the slider can be reduced. Furthermore, since the lubricant is impregnated into the buffer member and a part of the buffer member is in contact with the annular electrode, the lubricant can be applied on the annular electrode. Consequently, the sliding portion slides smoothly and the abrasion of the contact portion can be further reduced. In addition, since the buffer member functions to wipe the surface of the annular electrode, foreign substances such as dust on the annular electrode are collected. Thus, harmful effect to the contact portion by the foreign substances can be prevented. By the above described configurations, the rotary electronic component of the present invention can obtain the extended life time and high operation reliability.
