Patent ID: 7651367

Claim:
A socket for use with an electron package, comprising: an insulative housing including a base with a plurality of side walls commonly defining a package receiving cavity; a plurality of contacts disposed in the base; and at least one resilient arm located on one of said side walls and defining an engagement head thereof for engagement with said electronic package received in the package receiving cavity, said engagement head defining an inward engagement face facing the electronic package cavity for engagement with the package, and an upwardly tapered guiding face adjacent to the engagement face for guiding downward loading of the package into the package receiving cavity; wherein said one of the side walls defines an inner surface with a ledge at a top, and said upwardly tapered guiding face extends across a line defined by said ledge in a top view so that the guiding face is assured to be confronted by the package when the package is downwardly loaded into the package receiving cavity, thus resulting in a lateral deflection of the resilient arm.
