(Visual check or Slightly pull the terminal to check.)
NOTE: Repairing the crimp contact
For removing the inserted crimp case, lift up the mold lance by using DF-C-PO(B) or a
pointed needle and such, and pull out the cable simultaneously. The repair operation could
make the lance strength lower, therefore, do not reuse the crimp case and replace it to a
new one.

4. Precautions for handling
1 4.1. Loading to a connector
To pack or store assemblies, make sure overlapped connectors will not apply extreme load
to excessive external force applied to connectors could cause failure or damage.
Therefore, avoid forced insertion or removal, dropping impact, cable wiring (pull, twist) and
such.
Especially, the housing lance part of the crimp case has a spring shape and may be
deformed or damaged when a load is applied. Therefore, please do not handle the crimp
case by pushing the spring in the lance section or applying a load on top of the bag.
4.2. Wiring cable
Forcible wiring such as bending the cable near the connector and straining the cable, could
cause contact failure.
During cable wiring inside the machine, keep sufficient cable length for slack to avoid direct
stress is applied to the connector.
No cable tension is applied.
Sufficient cable length
