Name/Type Power connector Nikon D70?

Hi,

I'm looking for the name and or type of DC power connector used on the Nikon D70. I really want the mating connector so that I can build an external battery supply. I don't want to buy the EH-5 AC adapter just to get the cord. Can anyone help me out? It is a keyed, 4 pin plug rated for 3 amps, only 2 pins are used. The attached picture of the AC adapter label shows the plug.

Thanks,
Nick

I've been searching for the connector too with no luck. It looks that Nikon had it custom designed for them. Only hope in someone making an aftermarket version of the connector or, more likely, the adapter... or just buy a broken unit (good luck with finding one!). I'don't think just applying the voltage to the camera pins would work either. I think in the camera socket there is a switch which cuts off the battery when the plug is detected.
Let me know if you find something regarding the matter.

I am about to adjust a plug for my camera too. Could you please tell me if the above picture shows the pins of the plug(male) or the pins of the slot on the camera. Appreciate this, thank you.

The diagram in the photo is the connector. The camera is a mirror image of that.

Any more luck getting the connector separate? I have a similar need and I really don't want to spend $75 just for the connector.

Thanks!

I was in the same boat. Wanted to tether my D70 for time lapse photography but didn't want to spend $90 for the AC adapter. My solution, while not visually appealing, worked like a charm. I used the little CR2 battery holder that came with the camera. (The one the uses 3 of the CR2 batteries) Since this might just be the most expensive way you could ever power your camera I figured I'd never use it again. If you use yours you wont want to do this. I pulled all of the metal contacts out EXCEPT for the pos & neg ones on the end. Then I cut out the plastic dividers on the inside of the battery holder. I purchased a 9v/1A AC adapter from Radio Shack, along with the pigtail tip adapter. Soldered insulated clips to the pigtail and passed the pigtail through the hole at the bottom of the battery case. When you insert this in the bottom of the camera you can just about close the door. I used a little bit of tape to hold the door closed. I used this to shoot time lapse pics for 7 hours during a marathon and it worked like a champ.

Don't forget that you can power the regular AC adapter with an inverter running off a 12v gel cell battery. Those are good for 7 or 8 AH. Inverters run at over 90% efficiency, and the AC adapter may tun at considerably less efficiency of it is not a switching-type transformer. Nevertheless, you ought to be able to run the camera a long time this way and you will not have to butcher parts to make it work.
