Patent ID: 7674125

Claim:
An electrical connector for electrically connecting a pin leg of a CPU with a trace of a PCB, comprising: an insulative housing; and a contact comprising a base and a pair of arm sections oppositely extending from lateral sides of the base for engagement with the pin leg, the base having a body section for being secured in the insulative housing and a soldering section for being soldered onto the PCB, each arm section forming a heave to interfere with the insulative housing because of deformation of the arm sections, wherein each arm section comprises an upper arm extending obliquely and downwardly from one lateral edge of the body section toward the soldering section, an elbow at a bottom portion of the upper arm, a forearm extending obliquely and upwardly from the elbow, a contact region at a top portion of the forearm and a palm extending obliquely from the contact region toward the body section, wherein the heave is formed at each forearm, wherein the forearms define a first space therebetween and the palms define a second space therebetween, and the first space is in communication with the second space at a channel defined by the contact regions, wherein a portion of the first space between the elbows is wider than portions of the first space between the forearms, wherein a portion of the second space between the palms at the contact regions is narrower than portions of the second space between the palms which are closer to the body section, wherein the channel is narrower than both the first and second spaces, wherein the arm sections extend to a height substantially the same as a height of the base, wherein the base forms at least two projections on opposite lateral sides of the body section for securing the contact in the insulative housing, wherein the projections are formed above and below the body section.
