Electrical connector with improved terminals

An electrical connector comprising:

• an insulative housing;
• signal terminals disposed in the insulative housing;
• and
• grounding terminals disposed in the insulative housing and located proximate to corresponding signal terminals, the grounding terminal comprising a main part extending in an upright direction and a transverse direction and an upper elastic arm extending obliquely and upwardly from an upper face of the main part, the upper elastic arm defining an upper-arc contacting portion and an upper end bending from the upper-arc contacting portion;
• wherein the main part defines a first recess going through the upper face, and the upper end of the upper elastic arm is operable to move downward to enter the first recess.

An electrical connector comprising:

• an insulative housing;
• and
• a plurality of first terminals disposed in the insulative housing, each of the first terminal comprising a main part retained in the housing and an upper elastic arm and a lower elastic arm;
• wherein the main part defines a first recess opening upwards and a second recess opening downward, and a distal end of the upper elastic arm moves into the first recess when the upper elastic arm moves downwards and a distal end of the lower elastic arm moves into the second recess when the lower elastic arm moves in the second recess.

An electrical connector comprising:

• an insulative housing;
• and
• a plurality of first terminals disposed in the insulative housing, each of the first terminals comprising a main part retained in the housing and an upper elastic arm extending obliquely and upwardly from the main part, the upper elastic arm having an upper-arc contacting portion and an upper end bending downward from the upper-arc contacting portion;
• wherein the upper end defines a first contacting face, the main part defines a second contacting face confronting with the first contacting face, at least one of the first contacting face and the second contacting face is of an inclined face to guide the upper end of the upper elastic arm to contact with the main part, and the first and second contacting faces contact with each other when the upper elastic arm moves toward the main part;
• wherein the main part defines an upper face, a lower face opposite to the upper face, a first upright face, and a second upright face opposite to the first upright face, the first or the second upright face is larger than that of the upper face or the lower face in dimension, and the upper elastic arm extends from one end of the upper face;
• and
• wherein the first terminals are grounding terminals arranged in a row and connected with each other to form an integral shielding member, the insulative housing defines a groove through an upper surface and a lower surface thereof, and the integral shielding member is received and retained in the groove.
