Electrical connector with a pair of improved detecting pins

An electrical connector comprising:

• an insulating housing defining a base portion, a tongue portion extending forwards from a front face of the base portion and a pair of flanges located spaced from and parallel to two opposite end walls of the tongue portion, the flanges defining a recess portion at each of opposite inside surfaces thereof;
• a plurality of terminals, each defining a solder portion extending towards a bottom face of the base portion and a contacting portion located on the tongue portion;
• and
• a pair of detecting pins being located in said recess portions, each comprising a leg portion extending out the base portion and an arc section projecting out beyond the inside surfaces of the flanges to be touched by a sidewall of a shielding shell of a counter connector when the electrical connector is inserted by the counter connector.

An electrical connector comprising:

• a frame like metallic shell defining a pair of opposite main walls and a pair of opposite side walls commonly defining a cavity;
• an insulative housing received in the cavity and defining a base with a mating tongue extending forwardly therefrom, said mating tongue defining two opposite large main surfaces and two opposite tiny side surfaces perpendicular to said two opposite main surfaces, said main surfaces and said side surfaces commonly extending in a front-to-back direction from peripheral edges of a front face of the mating tongue, respectively;
• a plurality of spring contacts disposed in the housing with contacting sections exposed upon one of said large main surface for imposing an asymmetric force upon a complementary connector, which is inserted into the cavity, in a vertical direction perpendicular to the front-to-back direction and main surface while parallel to the side surface;
• and
• a pair of spring detecting terminals located around said two opposite tiny side surfaces, respectively, so as to impose essentially balanced and symmetric forces upon a metallic shield of said complementary connector along a transverse direction parallel to said large main surface while perpendicular to said side surface and said front-to-back direction and said vertical direction.
