Abstract

The present invention provides a flexible connection structure of a connector, and a vehicle, relating to the technical field of automobile manufacturing. The flexible connection structure of the connector comprises a connector body, an insertion terminal, a transition terminal, a flexible conductor, and a transmission conductor; the insertion terminal is disposed in the connector body, one end of the transition terminal is connected to the insertion terminal, the other end thereof is connected to one end of the flexible conductor, and the other end of the flexible conductor is connected to the transmission conductor. A connector having a flexible connection transition can resolve the problem of rigid fixation between a terminal and a transmission conductor, so that when a charging gun is inserted into the connector, the insertion terminal can have a certain amount of shaking in a direction of an insertion force of the charging gun at the moment of insertion of the charging gun, thereby easing an impact of the insertion force on the insertion terminal. In particular, when an angle between the insertion direction of the charging gun and the insertion terminal is excessively large, an impact force can be better reduced, greatly decreasing the risk of eccentric wear of the terminal, and improving the safety of high-voltage charging.
