Wires with a cross-section up to 0.35 mm , repairing
When repairing wires with a cross-section up to 0.35 mm 2 , new terminals must always be crimped on using Crimping Pliers Of Jpt Contacts VAS1978/9A , or Crimping Pliers (Base Tool) VAS1978/1-2 with mounted Head Adapter For Jpt Contacts VAS1978/9-1. Due to the low current strengths of these wires in the micro- to milli- range, terminals incorrectly crimped on lead to continuity resistances and cause malfunctions or failure of the respective system. The most frequent applications of these terminals are:
- Oxygen sensor
- Speed (RPM) sensor
- Mass Air Flow (MAF) Sensor
By using Crimping Pliers Of Jpt Contacts VAS1978/9A or Crimping Pliers (Base Tool) VAS1978/1-2 with mounted Head Adapter For Jpt Contacts VAS1978/9-1 , correct connection between crimp contact, wire and single wire seal is guaranteed. The tool is to be used only for the purpose described.
- Terminals in a normal and a gold-plated version are crimped on to repair wires. Always use the same version of repair terminal as that installed by the factory.
Crimping a new contact with single wire seal
- Insert Head Adapter For Jpt Contacts VAS1978/9-1 into Crimping Pliers (Base Tool) VAS1978/1-2.
- Place the single wire seal on to the repair wire - arrow -.
- When doing this, the smaller diameter of single wire seal must face direction of terminal to be crimped on.
- Open crimp pliers and place the repair wire end into stripping slot of crimp pliers - arrow -.
- Close crimp pliers completely - arrows -.
- Open crimp pliers again and remove the stripped wire end.
- Slide single wire seal in direction of stripped wire end until it rests flush with the wire insulation.
- Place new crimp terminal - arrow - into mount on crimp pliers.
- Insert the stripped wire end with positioned single wire seal into crimp terminal - arrow - until it makes terminal on "wire stop".
- Crimp the terminal, wire and single wire seal by closing crimp pliers completely.
- Open crimp pliers again and remove the finished crimped-on terminal.
A correctly performed crimp is distinguished by a clean compression of wire and single wire seal in the contact and has an impression on the rear side which identifies that the crimp was performed by a professional using the correct tool.
