7000 series plug-in contact rating?


 

Does anyone know if there's an official current-carry rating for the 7K main interface connectors. That is, maximum continuous DC through the connector's spring contact into the plug-in's board edge contact, per contact. Only the carry is needed, not the make or break ratings.

I think virtually every commercially made connector type has these and voltage specs too, but since the 7K ones are Tek-made, it may not be so clear. I'm hoping for some internal document or experimenting or experience or other, kind of like the empirically derived 7K power supply and plug-in load characteristics. Anything should help.

I believe a first estimate may be somewhere around 4 amps, since (I think) any one-wide plug-in may have only a single contact for each supply, yet be able to dump an entire supply well over 4A peak for a SMPS supply trying to launch but ticking in a 7XX4 frame, or continuously at the foldback limit in a linear 7XX3. Like say, when there's a shorted Ta cap in a plug-in.
