The technical scheme adopted by the utility model is as follows: the four-point contact terminal used for the smart meter connector includes a female row plastic and a hardware terminal, the female row plastic is provided with a terminal slot, and the hardware terminal is inserted into the terminal slot Inside, the hardware terminal is provided with a female head, a connection part and a contact part, the contact part is inserted into the terminal slot, the contact part is provided with an extended force arm, and the extended force arm is connected to the connection part, so The connection part is connected with a female head, the contact part is U-shaped, two opposite side walls of the contact part are disconnected, and the disconnected ports of the hardware terminal contact part are bent in an arc to form contact points respectively.

Further, the connection part is arranged in a U shape, an opening is provided in the middle of the side wall between two symmetrical side walls of the connection part, and an elastic piece is provided at the opening.

Further, the side wall of the master row plastic is provided with rectangular holes, the rectangular holes are evenly spaced, and the rectangular holes are provided with chamfers.

After adopting the above-mentioned structure, the beneficial effect of the utility model is as follows: The four-point contact terminal used for the smart meter connector proposed by the utility model has four contact points to transmit current and signal, which is better than the traditional two contact points. It is more reliable. By setting the lengthened force arm, the terminal force arm is lengthened to make the terminal more elastic and not easy to deform when mating.
