Insulation displacement method

The major advantage of the insulation displacement method lies in simplifying and speeding up the cable connection.

The insulation displacement method generally consists of a matched system of connector, PROFIBUS cable and wire stripper. Use only components that are designed to work together as described in the manufacturer’s instructions, otherwise problems may occur

When using the insulation displacement method, the cable end must be cut off for every connection (e.g. when changing connectors). Never re-use the cable-ends without cutting them off after a connector has been removed, otherwise a poor contact may result.

 

 

Read the manufacturer’s instructions these instructions may provide important information about the connector design and use.
 

The basic steps are as follows:

  1. open the connector.



  2. Pass the cable through the screwed gland and any other parts of the connector that are required.



  3. Strip the insulation from the cable; ensure that the stripped cable dimensions are applicable to the connector you are using (observe the connector manufacturer’s data).



  4. Connect the shield; ensure that there is no contact between the shielding and the cores.



  5. Insert the cores in the opened contact block.



  6. Close the contact block.



  7. Close the connector housing and screwed gland to provide strain relief on the cable and seal the connector.

  8. Seal the connector.


 

Manufacturers often supply wire strippers that match their insulation displacement connectors. Such tools significantly speed up and simplify the connection procedure.

Wire strippers can be adapted for different shielded cables by using different cutter cassettes. Ensure that the cutter cassette being used is correct for your cable/connector system.
