Patent ID: 7938649

Claim:
An electrical connector comprising: a plurality of contact units, each contact unit having a top contact and a bottom contact, the top contact formed with a keeping portion and a lower mating end downwardly; the bottom contact having a pair of mating beams extending vertically for engaging with the lower mating end of the top contact; a lower housing defining a plurality of through gaps for receiving the bottom contacts; and; an upper housing mounted upon the lower housing and defining a plurality of receiving slots for receiving the top contacts; wherein when the top contact approaches the bottom contact two mating beams in a top-to-bottom direction under a pressed force, elastic force is generated by the pair of mating beams due to elastic deformation and acts on the lower mating end, thus making the pair of mating beams of the bottom contact mechanically and electrically engage with the lower mating end of the top contact; wherein the pair of mating beams extends gradually approaching to each other in the top-to-bottom direction; wherein a channel is defined by the pair of mating beams, and provides a space to allow movement of the lower mating end of the top contact under a condition that dimension of the channel is gradually reduced in the top-to-bottom direction; wherein the bottom contact comprises a main portion extending vertically with a bight portion arranged on a top end of the main portion, wherein the pair of mating beams extends from the bight portion.
