A connector or socket for detachably mounting an integrated circuit unit on a printed circuit board has single beam contact members precisely located and secured in respective recesses in an electrically insulating body by guiding wing portions of the contacts against shaped body portions which are then deformed over the wing contact portions to secure the contacts in the recesses. The contact members are formed of a strip material and each have a base with lateral wing portions, a spring beam part extending up from one end of the base to loop over the base, and a post part extending down from the opposite end of the base, the beam and post parts each preferably having a stiffening rib formed therein and extending into the base part to assure that the contact parts have a desired angular relationship to each other. The connector body has recesses which are open at their bottom end to freely receive the looped contact portions therein, has locating steps in the open bottom ends of the recesses, and has tapered tower portions between the recesses to engage and guide the wing contact portions against the locating steps and to be deformed over the wings for securing the contacts in the recesses. The body has tapered apertures of novel configuration communicating with the opposite ends of the recesses to provide versatile and more reliable guiding of i.c. terminals into engagement with the contact while providing improved terminal insertion, terminal contacting and terminal withdrawal force characteristics.
