Contact connecting device capable of preventing metal collision

The utility model discloses a contact connecting device capable of preventing metal collision, which comprises a through-flow base, a socket arranged on the through-flow base and a pipe conductor inserted in the socket, and is characterized in that the bottom of the socket is provided with a gasket for preventing metal collision between the lower end of the pipe conductor and the bottom of the socket. The device provided by the utility model realizes the electric connection between the contact base and the pipe conductor in the high-voltage bus, prevents metal collision which may occur between the pipe conductor and the contact base due to bumping and vibration during transportation, and eliminates the possibility of generating metal powder.
