Abstract

An electrical connector for electrically connecting a CPU to a main board includes a base covered with a cover. The cover has a periphery defining an indentation therein and is formed with two pairs of tabs extending towards the base. The cover and the base are connected in a manner of allowing the cover to be movable on the base. A rotor is situated between the cover and the base near the periphery of the cover. The rotor has a middle portion and a pair of radial cams. The middle portion is provided with a slot and positioned in the indentation of the cover, and the cams have a profile designed to engage with the tabs of the cover. Therefore, the cover can be moved relative to the base when the rotor is turned by any tool extending into the slot of the middle portion.

Claims

1. An electrical connector comprising:

a base (20);

a cover (10) atop said base (20), said cover (10) having a periphery defining an indentation (11) therein and being formed with two pairs of tabs (13) extending towards said base (20);

said cover (10) and said base (20) being connected in a manner of allowing said cover (10) to be movable on said base (20);

a rotor (30) situated between said cover (10) and said base (20) near said periphery of said cover (10), said rotor (30) having a middle portion (31) and a pair of radial cams (32) at sides of said middle portion (31); and

said middle portion (31) being provided with a slot (312) and positioned in said indentation (11) of said cover (10), said cams (32) having a profile designed to engage with said tabs (13) of said cover (10);

wherein said rotor (30) has a pair of enlarged ends (33) and two collars (311) that are formed on both sides of the middle portion (31), wherein said base (20) is defined with respective outer recesses (23) and inner recesses (25) for respectively and snugly receiving said enlarged ends (33) and said collars (311);

whereby said cover (10) can be moved relative to said base (20) when said rotor (30) is turned by any tool extending into said slot (312) of said middle portion (31).
