Rakesh Anderson Posted January 9, 2014 Report Share Posted January 9, 2014 I just finished wiring a hirose connector to an NP-1 battery cup. Is pin 1 shorted to the housing of the hirose by design, or did screw it up? There is continuity between the negative battery tab in the cup and the housing of the hirose. I took it apart and couldn't see anything obviously screwed up, and I don't have another example to compare. Any help would be appreciated. Thanks Quote Link to comment Share on other sites More sharing options...

studiomprd Posted January 9, 2014 Report Share Posted January 9, 2014 hint: none of these connectors are built with pins connected to the shell.... if it is plugged in, then a pin may be connected internally to the chassis Quote Link to comment Share on other sites More sharing options...
Rakesh Anderson Posted January 9, 2014 Author Report Share Posted January 9, 2014 Thanks. I must have screwed it up. pin 1 and chassis are shorted when not plugged in. I appreciate it. I tightened the set screw and it pushed one of the crimp teeth through the insulation. I knew that was going to happen. Quote Link to comment Share on other sites More sharing options...

Glen Trew Posted January 12, 2014 Report Share Posted January 12, 2014 I doubt this would have caused a problem, but it's not necessary. To be sure, it's best to not connect pin-1 of the power cable connector to the shell. gt Quote Link to comment Share on other sites More sharing options...
soundtrane Posted January 12, 2014 Report Share Posted January 12, 2014 use some teflon sleeve... or use the hirose model that uses a clinch rather than the crimp. Quote Link to comment Share on other sites More sharing options...
