Abstract

An electrical receptacle connector includes a shell, a first insulator, a second insulator and a blanking contact. The first insulator is disposed in the shell. The first insulator has a first insulator front end and a first insulator rear end. The second insulator is disposed in the shell and installed on the first insulator. The second insulator has a combining area. The blanking contact includes a fixing portion, a soldering portion, a contact portion and a combining portion. The fixing portion is combined with the first insulator. The soldering portion protrudes from the fixing portion toward the first insulator rear end and stretches out of the first insulator rear end. The contact portion protrudes from the fixing portion toward the first insulator front end and stretches out of the first insulator rear end. The combining portion protrudes from the contacting portion and inserts into the combining area.
