| For repairs to wiring with cross sections up to 0.35 mm2,
it is essential that contacts are crimped on using crimping
pliers for JPT contacts -VAS 1978/9A- or crimping pliers (base
tool) -VAS 1978/1-2- with attached head adapter for JPT contacts
-VAS 1978/9-1-. Due to the low current strength of these wires
in the micro and thousandths range, incorrectly crimped contacts
cause electrical resistances and result in faults or failure in
the respective system. The most common applications of these
contacts are: |
| With the use of crimping pliers for JPT contacts -VAS
1978/9A- or crimping pliers (base tool) -VAS 1978/1-2- with
attached head adapter for JPT contacts -VAS 1978/9-1-, the
correct connection between crimp contact, wire and single wire
seal is assured. The tool is only to be used for the application
described. |
 Note
| Crimped to the repair wiring are normal contacts and
gold-plated contacts. The repair contact must always be the same
type as the contact installed in the factory. |

|
|
|
| – |
Attach the single wire seal to the repair wire. |
Note
| When doing this, the small diameter of the single wire seal
must face the contact to be crimped on. |
|
|
|
| – |
Open the crimping pliers and insert the end of the repair
wire in the opening of the crimping pliers for wire stripping. |
|
|
|
| – |
Close the crimping pliers fully. |
| – |
Open the crimping pliers again and removed the stripped wire
end. |
|
|
|
| – |
Push the single wire seal towards the stripped wire end
until it is flush with the wiring insulation. |
|
|
|
| – |
Insert the new crimp contact in the mounting of the crimping
pliers. |
|
|
|
| – |
Insert the stripped wire end with the positioned single wire
seal in the crimp contact until it comes into contact with the
“wire stop”. |
| – |
Crimp the contact, wire and single wire seal by closing the
crimping pliers fully. |
| – |
Open the crimping pliers again and remove the successfully
crimped contact. |
|
|
|
| Successful crimping can be identified by clean and equal
application of pressure on the wire and single wire seal in the
contact and by a stamp on the rear that indicates the correct
tool was used in the correct manner to carry out the crimping
process. |
