An electrical connector (10) includes a base (101), and a cover (102) locatable above the base. The base has a major surface (1011) with a plurality of terminal receiving passageways (1010) extending therefrom. The cover has a major face (1025) opposite the major surface and spaced apart from the major surface of the base. A plurality of discrete protrusions (1012) is arranged extending longitudinally from one of said major face and said major surface towards the other, and positionable adjacent the passageways. Thus, a plurality of voids is located laterally adjacent the discrete protrusions and between the major surface of the base and the major face of the cover, thereby allowing the heat from pin-like conductive elements (21) of a CPU chip (20) to be dissipated through the plurality of laterally voids around the pin-like conductive elements.
