ABSTRACT:
An improved electrical jack assembly (20) for converting to modular use a telephone terminal block (10) with screw terminals (11) is disclosed. Leads (32) in the jack assembly connect at one end (31) to contact elements (27) in a modular jack (22) affixed to an assembly housing (21) and at the other end (33) to screw-engaging connectors (34), each of which comprises a body (37) of conductive material with a base (40) and a plurality of resilient elongate members (42) extended therefrom. The free end portions (45) of the members (42) include sharp-pointed contact tips (47). The free end portions (45) also tend toward one another to define with their tips (47) an opening (48) for snugly receiving a head (12) of an assigned screw terminal (11), where the tips (47) can bear against the screw head (12) to effect reliable electrical and mechanical connection.
