Melted Power Connector
Posted: Mon Jun 02, 2014 7:03 am
I have just come down with a case of melted power connector, here manifested as loss of power to the HBP and fusing of the male and female 6 pin connector where the power supplies mate with the RAMBo. This is an old-style two power brick supply and a RAMBo 1.0d. So far I've read through a number of posts here and on the old google group and it seems like people have resolved this problem with one of the following options:
1) simply replace the melted connectors (male and female) and hope for no repeat problems and/or add additional clamping or strain relief to prevent a loose connection
2) remove the connectors and solder suitably sized wires to the board, terminated in anderson powerpole (or similar) connectors, strain relief required.
3) upgrade to 24v
4) (hypothetical) replace the melted connectors, but plug the HBP supply into a DC-DC relay and drive that from RAMBo.
If there are any fixes for this that I missed, please say so.
What is the consensus view on these options -is there a preferred way forward here without upgrading to 24v? Does anyone know of a drop-in replacement connector that is better able to handle the current of the HBP? My soldering skills are not fantastic, so I'm reluctant to try anything too fancy; nevertheless, the existing connector clearly needs to be replaced. Thoughts?
