Abstract: An electrical receptacle comprises a longitudinally supple intermediate section and a contact section. The contact section has a box-shape formed by side walls and top and bottom walls, where cantilever beam contact arms extend from opposing side walls and are attached proximate a mating end. Free ends of the contact arms bias against tabs that extend from the top and bottom walls. The top and bottom walls comprise spring beams that provide the main spring force for the contacts. The arrangement of the contacts and spring beams uses material effectively and enables easy manufacturing for miniature contacts. High contact forces are nevertheless achieved.
