Electrical connector with strengthened actuation device

An electrical connector for electrically connecting an electronic package with a circuit substrate, the electrical connector comprising:

• a base comprising an end portion defining a locating slot therein and a main portion receiving a plurality of electrical terminals therein, the end portion forming locating walls at the locating slot;
• a cover slidably attached on the base and defining a receiving slot corresponding to the locating slot of the base, the receiving slot and the locating slot cooperatively defining a receiving space;
• and
• an actuation device rotatably received in the receiving space, and comprising first actuating portions and a second actuating portion;
• wherein each of the first actuating portions has a first locating surface and the second actuating portion has a second locating surface, the first locating surface and the second locating surface are oriented at an angle relative to each other, and are respectively engaged with respective of the locating walls when the actuation device is rotated between an open position and a closed position.

An electrical connector comprising:

• an insulative base with a plurality of terminals therein;
• an insulative cover mounted on the base and moveable relative to the base in a front-to-back direction;
• said base and said cover commonly defining a retaining slot extending in a transverse direction perpendicular to said front-to-back direction;
• an actuation device received in the retaining slot and rotatable about an axis along said transverse direction;
• and
• first and second actuation portions formed on different axial positions along said axis, each of said first and second actuation portions defining opposite camming surface and abutment surface;
• wherein
• when the cover is in an open position relative to the base, the camming surface of the first actuation portion is engaged with the cover and the abutment surface of the first actuation portion is spaced from the cover, while the camming surface of the second actuation portion is spaced from the cover and the abutment surface of the second actuation portion is engaged with the cover;
• in contrast, when the cover is in a closed position relative to the base, the camming surface of the first actuation portion is spaced from the cover and
• the abutment surface of the first actuation portion is engaged with the cover, while the camming surface of the second actuation portion is engaged with the cover and the abutment surface of the second actuation portion is spaced from the cover.
