Problems solved by technology

However, for the above-mentioned conventional rotary connector 120, if a large current flows through the conductor part of the flexible cable 103, excessive heat will be caused due to the wiring resistance heating of the conductor part, so its current value has a certain value. Therefore, it becomes a problem to supply enough current to the heating device through 1 flexible cable 103 to make the heating device generate heat
