Connector

The invention discloses a connector provided with a partition plate elastic arm, which comprises a molded part, an upper row of terminals, a lower row of terminals and a metal middle partition plate, and is characterized in that at least one part of the metal middle partition plate is wrapped by the molded part; the metal middle partition plate comprises an elastic arm, and the elastic arm penetrates out of the vertical wall of the molded part and obliquely extends. And when the wire end connector is plugged with the board end connector, the shell of the wire end connector compresses the elastic arm and forms grounding communication with the elastic arm and the metal middle partition plate in the board end connector. When the line end connector and the board end connector are plugged and then are affected by the outside to cause loose fit tolerance, due to the elasticity of the elastic arm, the shell of the line end connector can still form stable connection with the metal middle partition plate. And the shel
