WIRING A STANDARD PHONE PLUG (2-conductor)
Parts identification.
Slide shell, then insulating collar over cable end. Strip
outer insulation for length equal to length of sleeve con-
nection. Unwrap or unbraid shield, twist to form lead.
Position outer insulation just ahead of cable clamp,
strip center conductor from point just behind tip con-
nection. Tin center conductor and shield. Bend shield as
illustrated, solder to outer surface of sleeve connection.
(Cool immediately with pliers.) Insert center conductor
in tip connection, solder, cut end flush. Bend the end of
the tip connector (slightly) toward the sleeve connection
to help prevent the burr (from the cut wire) from cut-
ting through the insulating collar.
Using pliers, bend cable clamp around outer insula-
tion. Clamp should be firm, but not so tight as to cut
insulation.
Slide insulating collar forward, until flush with rear
of threads. Slide shell forward, screw tight to plug
assembly.
WIRING A TIP, RING &
SLEEVE PHONE PLUG (3-conductor)
Parts identification.
Slide shell and insulating collar over cable end. Strip
outer insulation for length equal to length of sleeve con-
nection. Remove any tracer cords and strain relief cords.
Form lead from shield. Hold cable with outer insulation
just ahead of cable clamp, and strip the red (or white)
conductor just behind the tip connection. Then strip
the black conductor just behind the ring connection.
Tin all leads, and cut the center conductors so approxi-
mately 1/8" of bare wire remains.
Solder the shield to the outer surface of the sleeve
connection, allowing enough free shield to bend around
to the other side of the cable clamp. Cool the connec-
tion immediately with pliers.
Insert the center conductor leads in their respective
connection points, and solder in place. Trim the leads
flush. Bend the end of the tip connection (slightly)
toward the ring connection to help prevent the burr
(from the cut wire) from cutting through the insulating
collar.
Using pliers, bend the cable clamp around the outer
insulation. The clamp should be firm, but not so tight
as to cut the insulation.
Slide the insulating collar forward, until flush with
rear of threads. Slide the shell forward, and screw tightly
onto plug.
