Electric rotary joint

The utility model discloses an electric rotary joint relates to the electrical equipment field, can be connected through the electric wire fixed knot structure with binding post when this electric rotary joint uses, is connected revolution mechanic with the wiring pivot, and wiring pivot, electrically conductive carousel, conducting solution, binding post form the route, owing to electrically conductive carousel can be at the inside free rotation of shell, so this electric rotary joint constructs revolution mechanic transmission power from fixed knot when can be used to the unrestricted rotation in succession of requirement revolution mechanic. And because the wearing and tearing between electrically conductive carousel of rotatory in -process and the conducting solution are very little, make electrically conductive carousel and conducting solution's loss little, can prolong its life. 本实用新型公开了种电气旋转关节，涉及电气设备领域，该电气旋转关节使用时可将固定结构通过电线与接线端子连接，将旋转结构与接线转轴连接，接线转轴、导电转盘、导电液、接线端子形成通路，由于导电转盘可以在外壳内部自由旋转，所以该电气旋转关节可用于要求旋转结构无
