| (54) | Modular plug for high speed data transmission |
| (57) Shielded modular plug (15) for category 5 applications comprises a plug housing (13)
and a wire holder (10). The wire holder comprises a housing (20) with wire receiving
cavities (22) extending therethrough, and a base wall extension (35) extending from
the housing to a front end (36). The wire holder is assembled to the cable by inserting
straightened wire ends into the cavities (22) of the holder and pulling the holder
tightly against the twisted pairs of the cable. The wire ends (6) can then be trimmed
with the front end (36) acting as the reference. The wire holder and cable ends are
then inserted into the cavity (48) of the plug housing until a fully inserted position
where the plug contacts (18) are positioned above the wire ends (6), and can be depressed
for piercing through the insulation to contact the inner conductors. Due to tightening
of the wire holder against the twisted pairs, the length of straightened cable is
as short as possible thereby reducing crosstalk interference and enabling higher data
transmission speeds. Furthermore, tightening of the wire holder against the twisted
pairs ensures that connections are made in a reliable manner with less sensitivity
to variations in the assembly procedure. |
