Heat shrink tubing and bare crimp terminal
Peeling a power cable
Crimping the joint parts of the bare crimp terminal
and the conductor (OT terminal)
Heating the heat shrink tubing
1. Based on the cross-sectional
area of the cable conductor,
strip a part of insulation
coating C to expose the
conductor D of length L1.
2. Put the heat shrink tubing
onto the bare crimping
terminal.
3. Put the OT terminal B onto
the exposed conductor, and
ensure that the OT terminal
is in good contact with the
insulation coating C.
4. Crimp the joint parts of the
bare crimp terminal and the
conductor.
5. Push the heat shrink tubing
toward the connector until
the tube covers the crimped
part, and then use a heat gun
to heat the tube.
