Description

Technical Field

[0001] The utility model relates to the technical field of guide connectors, in particular to an automatic guide connector for an electric operating shaft. Background Art

[0002] With the development of intelligent technology, the switch cabinet trolleys have been gradually replaced by electric operation instead of manual operation. If electric operation trolleys are used, the trolleys can be remotely controlled to enter and exit, which improves work efficiency, ensures the personal safety of operation and maintenance personnel, and also meets the needs of the development of intelligent technology.

[0003] The existing switch cabinet trolleys are mostly converted to electric operation by adding an external electric operating device. Since a certain angle deviation occurs when the output end of the external electric operating device engages with the manual operating hole of the original trolley chassis, it is necessary to manually adjust the angle to ensure that the output end of the external electric operating device is consistent with the manual operating hole of the original trolley chassis, thereby realizing the electric operation function; manual operation requires human participation, which hinders the realization of overall automation.

[0004] In view of the above, the present application proposes an automatic guide connector solution for an electric operating shaft, which does not require additional manual adjustment or alignment operations and realizes automatic control, thereby greatly improving the movement efficiency of the trolley chassis in the switch cabinet.
