Procedure
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
7
the exposed conductor, and
7
ensure that the OT terminal
is in good contact with the
7
insulation coating C.

4. Crimp the joint parts of the
bare crimp terminal and the
9
conductor.

5. Push the heat shrink tubing
toward the connector until
13
the tube covers the crimped
14
part, and then use a heat gun
to heat the tube.
