Disclosures of the present invention mainly describe an electrical connector set mainly consisting of a space-end electrical connector disposed in a battery accommodating space and a battery-end electrical connector connected to a replaceable battery. The space-end electrical connector is integrated with a first outer circular cylinder member and a first inner circular cylinder member therein. In contrast to the space-end electrical connector, the battery-end electrical connector is also provided with a second outer circular cylinder member and a second inner circular cylinder member therein. By such arrangement, after connecting the battery-end electrical connector with the space-end electrical connector, the outer wall of the first outer circular cylinder member contacts with a circular negative electrode of the second outer circular cylinder member and the outer wall of the first inner circular cylinder member contacts with the circular positive electrode of the second inner circular cylinder member.
