An electrical connector is revealed. The electrical connector includes an insulating body with at least one terminal receiving hole and an accommodation space disposed on one side of the terminal receiving hole, at least one conductive terminal set that is received in the terminal receiving hole and having a first conductive terminal and a second conducive terminal, and at least one elastic member. The first conductive terminal is connected with the second conductive terminal slidingly and slantingly and the sliding stroke of the first conductive terminal is between the terminal receiving hole and the accommodation space. Each elastic member is correspondingly mounted in one of the accommodation spaces for elastically supporting the first conductive terminal. That means each elastic member gives the first conductive terminal a horizontal lateral force so that the first conductive terminal always applies a normal pressure to the second conductive terminal. Thus the good contact between the two conductive terminals is ensured.
