How should the wires on connector X106 be fixed to prevent damage to the connector and socket in the i950?
Feedback from customer applications with moving control cabinets indicate that contact interruptions and sparking occasionally occur at the spring contacts of the connector x106 and the pins in the i950.
Connectors with discolouration and/or charred contacts are observed here.
Movements of the wiring harness, as typically occurs with moving control cabinets, could be identified as the cause.
A movement of the connector while a high braking current is conducted causes the connector to age more quickly.
Necessary cable fixation for travelling enclosures:
A vertically acting load on the connected cables and any movement of the connector in the socket must be avoided in a suitable manner.
The photo shows a wiring example.
The wires at the brake connector X106 are combined into a wiring harness with the wires of the brake supply X107 and have a length reserve (small bend).
The fixation at a short distance in front of the connector increases the stability against lateral movement.
