Abstract
Abstract In a charging connector for an electric vehicle for charging a power receiving connector coupled with a power supplying connector, the power supplying connector includes an outer housing to be coupled with said power receiving connector; an inner housing to be slidably mounted on the front half and housing a plurality of terminals; and an air cylinder mounted inside said outer housing inside the rear half of said outer housing and a piston connected to the rear end of said inner housing. Whereby the inner housing is driven toward said power receiving connector by the operation of said air cylinder so that said terminals are connected to corresponding terminals of said power receiving connector. In such a configuration, since the advancing drive of an inner housing in which terminals are housed is carried out using the air cylinder, a small number of components can be used and the piston has only to be connected to the rear end of the inner housing, thus simplifying the production cost and reducing the production cost.
