Terminal of socket connector

Abstract

A socket connector includes a housing positioned on a circuit board and movably supporting a cover. Cells are defined in the housing for retaining dual-beam terminals. The cover carries a central processing unit module having pin legs extending through holes defined in the cover and projecting into the cells of the housing. The cover is movable in a moving direction to bring the pin legs into engagement with the terminals. Each terminal includes a base section retained in each cell and a tail extending and beyond the housing for being soldered to the circuit board. Two beams extend from the base section, substantially opposite to the tail. Each beam forms a spring arm. The spring arms are opposite to and spaced from each other for engaging the corresponding pin leg therebetween. The beams are symmetric with respect to an imaginary plane that is normal to the base section and coincident with the moving direction. Each beam has a major surface angularly offset from the imaginary plane and thus forming a first included angle with the imaginary plane. The major surface also forms a second included angle with the base section. The included angles are smaller than 90 degrees and greater than 0 degree. Preferably, the included angles are 45 degrees. The angularly offset configuration of the beams allows easy adjustment of the space between the spring arms and thus adjustment of the performance parameters of the terminals.
