Title: "Hirose" connector
Post by: connloyalist on August 30, 2016, 10:29:10 AM
The "hirose" connector we talk about here in audio land... is the strict definition a "Hirose 4-pin connector"? I am looking for the exact phrase to use in my (soon to be and probably futile) attempt to convince Power Traveller to build a Hirose connector for the Power Gorilla.

Wouldn't it be easier to get one of our resident cable builders to build you a connector?  That's what I did for my F8 and RAVPower unit.  Works like a charm!

^  To add my 2 cents, Ted Gakidis has built me a few Hirose cables to power my SD MixPres and they're great, very well made.  He even put together a Hirose adapt-a-plug tip at my request and it works beautifully.

Hirose is the company.  The 4 pin connector model numbers for the push pull plug type that are soldered to a cable on both ends are HR 10A-7P-4P for the male side and 10A-7P-4S for the female side.  If you're going to mount a receptacle to the side of your battery, the receptacle would be HR 10A-7R-4S with the same male side plug (HR 10A-7P-4P).  Note that if you wanted to you could swap the receptacle to be male and the plug to be female.  Just swap the S and P designations at the end of each part number in that case.

Thanks all. On a side note... why are 4 pin connectors used if only two wires are actually connected?

Two answers I can think of but I'm not an expert.  First is that a hirose connector of this design doesn't come in a two pin model. Second i can't fully answer but it seems to me it would have to do with the concept that many electrical connectors use at least a third pin for ground...and in the case of the xlr size connector the four pin is a standard connector for power which differentiates it from the three pin xlr cable used for audio.
