Impedance matched cable assembly having latching subassembly

摘要

A terminating connector (22) for a data transmission cable (20), wherein the cable (20) is of a known characteristic impedance and is of the type having a signal carrying conductor (26) and a shield (24). The connector (22) is typically arranged to mate with a complementary connector of a backplane. An overmolded subassembly (46) of the connector (22) includes a first terminal (32) electrically coupled at one end thereof to the shield (24), and a second terminal (34) electrically coupled at one end thereof to the signal carrying conductor (26). A dielectric insert (44) is disposed between the first and second terminals (32, 34). The insert (44) is dimensioned and has a dielectric constant such that the characteristic impedance of the subassembly (46) substantially matches the characteristic impedance of the cable (20). The subassembly (46) also includes a latch mechanism (60) for latching to a surrounding housing (28).
