Abstract

Abstract A connector (10) comprising an index strip (100) with wire-retaining slots (112) for receiving individual conductors (20), a connector module (200) with wire-engaging contact elements (40) and an index-strip portion (203), and a module cap (300). The wire-retaining slots (112, 212) in the index strip and index-strip portion of the connector module have flexible inwardly curved flanges (130, 230) adjacent to one end of the slot. Each corresponding pair of flanges, which depend from adjacent slot-defining upright members (110, 210), deflect inwardly into the wire-retaining slot during wire indexing to securely grip an inserted conductor (20, 30), the deflected flanges being capable of biasing toward each other to create an even tighter grip on a conductor when conductor pull out from that end is attempted. The flanges also tend to center each associated conductor in its associated slot, thereby minimizing the effect of misaligned stuffer means either in the connector module or cap during final positioning of conductors in the index strips. The flanges cooperate with aligning means (150, 250) adjacent to the other end of the wire-retaining slot to center each conductor along the entire slot. The connector also includes novel interlocking features which strengthen the structure of the connector and aid to improve the water resistance and the dielectric properties of the connector when assembled.
