Abstract
Abstract The invention is an improved optical fiber connector of the type comprising two identical plastic support members (11) having therein at least one V-groove on a first surface. The two support members are identical, with the V-grooves (12) being adapted to clamp on opposite sides of an optical fiber (16). In one embodiment of the invention, each of the support members has integrated therein a first spring member (20). First and second alignment pins (17, 18) are located on opposite sides of the matched first and second support members (11). The spring member (20) of a first one of the support members bears against one of the alignment pins (18) and forces it against the first and second support members (11); and the other spring member (19) forces the other one of the alignment pins (17) against the first and second support members. The springs are both preferably leaf springs which extend in a direction parallel to the V-grooves. By integrating a spring member into each plastic support member, one avoids the need for applying a spring clip substantially surrounding the two support members.
