Electrical receptacle connector

An electrical receptacle connector, adapted to be in contact with a plurality of conductive surfaces of a conductive substrate, wherein the electrical receptacle connector comprises:

• a terminal retaining member;
• an insulated housing formed out of the terminal retaining member, wherein the insulated housing comprises a base portion and a tongue portion, the base portion is extending from one of two ends of the base portion, and a mount member is assembled at the other end of the base portion;
• a plurality of first receptacle terminals, wherein each of the first receptacle terminals comprises a first flat contact portion, a first body portion, and a first tail portion, each of the first flat contact portions is extending forward from the first body portion in the rear-to-front direction and on a first surface of the terminal retaining member, each of the first tail portions is extending backward from the first body portion in the front-to-rear direction and extending out of the base portion, and the first tail portions are on the mount member and in contact with the conductive surfaces;
• an outer shell enclosing out of the base portion, wherein the outer shell comprises two side plates extending toward two sides of the base portion, each of the side plates has a slidable groove;
• and
• an embedded member between the side plates and on the mount member, wherein two sides of the embedded member have two slidable blocks for engaging with the slidable grooves, respectively, and a plurality of stopping blocks is extending outwardly from a bottom of the embedded member.
