Title: Nikon battery mating contacts - anyone know what they are?
Post by: VK3DRB on November 15, 2021, 03:36:36 am

Hi.

I am designing a battery powered product that will use an external charger and Li-Ion or Li-Po batteries (preferably about 7V, 2Ah). Low volume, so I am considering piggybacking off the Nikon camera battery which ticks all the boxes.

I have having a real difficult time finding the mating PCB mount contact block for a standard 7V Nikon battery EN-EL15.
There are five contacts, each 2mm apart. The mating contacts look like blade types as shown in one of the images.

I know manufacturers in China use these blade type connectors in their aftermarket Nikon battery chargers. But I cannot find any info on the connector.

Does any body know where I can source where I can source these blade type connectors (in the charger, not in the battery) and what the part number is?

Any help greatly appreciated.

cheers,
Dave

Looks like they are just called "blade type battery connector". There's 2mm and 2.5mm pitches.

Wow thanks! That is a start. I will contact them about a 5-pin version of "SMT battery connector", although a pin-through hole version is not out of the question. Maybe get a drawing and get some samples in. This battery connector does not have locating protrusions at each end.

If it goes well, I owe you a beer.
