Latest revision as of 07:15, 23 September 2019

One current problem we need to address is to choose a capable standard connector so that everyone can participate and prepare equipment before the next camp so that time is not wasted trying to connect everything together.

The discussion tab can be used to debate the various types of connectors.

It would be worth listing the connectors that have been tried but are not suitable with reasons too, for example, car cigarette connectors. Although rated for 10A, this happened at 30V@5A.

Connector requirements

We have some requirements on our connectors which need to be met with varying importance. Key Words according to rfc2119. Please expand this list. :

High Voltage Connectors

  • Must have at least 3 Pins (PE, GND, V+)
  • Must be lockable to prevent unplugging when loaded or alternatively this must be prevented by a different measure.
  • Must be able to handle the load and voltages
  • Should not be commonly used for different applications in a Camp context. If this cant be prevented damage to the different application and ours must not occur when connected with each other.
  • Should be Waterproof
  • May have added pins for communication. <- This may change to a "must have" depending on our implementation of load sharing.
  • Must prevent touchable live connections. This may be implemented by a different measures.

Low Voltage (< 50VDC) Connectors

  • Should have at least 3 Pins (PE, GND, V+)
  • Must be lockable to prevent unplugging when loaded or alternatively this must be prevented by a different measure.
  • Must be able to handle the load and voltages
  • Should not be commonly used for different applications in a Camp context. If this cant be prevented damage to the different application and ours must not occur when connected with each other.
  • May have added pins for communication. <- This may change to a "must have" depending on our implementation of load sharing.
  • Should prevent touchable live connections. This may be implemented by different measures
