510 batt connector-insulator

[Rocketman]

I've seen many posts where folks are having one heck of a time putting the insulator back in a 510 connector after taking it out to solder. I used to fight them also until I started doing it the right way

Even if you are careful you will probably degrade the insulator to solder to the connector. It may look OK, but it's life has been shortened. So take it out.

Take a CLOSE LOOK at the insulator and you will see a bevel on the lower edge. This is to press the insulator in. Lubicate the insulator (spit or a little PG) place it in the connector from the outside with bevel facing down. Take a 3/16 inch drill bit (not the cutting end) and slowly press the insulator into place. The white insulators from most cartomizers seem to be a little tougher than the clear ones (free spare parts).

Then press the center pin in. Ta Da !!

I second the carto insulators statement.

Nice tip Rocketman!

The insulators in my old 2009 510 batts have gotten brittle.

I used heat shrink tubing on a couple mods to replace insulator.

I use solder to build a dome on contact patch so it easily contacts all attys/cartos.

Mine where white rubber which I'm not crazy about.

I would prefer silicone.

I think if you heat them with a soldering iron you will see the difference. These follow normal rubber bushing design. They may be a neoprene material. White neoprene is used in food processing equipment.

Bevel for installation, retaining groove, and flange for axial pressure from the carto.

Sorry no pic.
The heat shrink tube follows all the contours of center pin and provide insulation and axial support.
A dab of RTV seals the deal.

I just didn't have any new flexible insulators on hand at the time. The heat shrink tube lasted several months on heavily used PT. Still works just don't use that PT anymore.

We are probably just talking in circles.

It's all good.

I hate the silicone and the rubber.I drill out my connectors and add a nylon sleeve.than replace the center contact with a copper nail.

 

[Rocketman]

Nylon probably holds up better than any of the floppy rubber insulators. That's a great idea. Do you make your own or have you found a 'secret' source for the right size Nylon bushings? SHARE

The flat surface of a carto probably has a higher contact area with a flat battery center pin (if kept clean).

After ripping yet another terrible rubber insulator the other day, I would love to find a source for nylon insulators.

Me too.
Nylon sounds great.

Heat shrink tubing can be found locally in case you can't find nylon in time.

I don't know off hand what they are used for or where too get them.I got them for my work(auto body shop)but on monday I'll get a part number and manufactor for you guys.I would bet you could find some thing like them at lowes or home depot.

 

[meatsneakers]

I've looked through the hardware draws at HD and the smaller sizes aren't small enough, but something from here should work. I'm away from my calipers right now but it's a start.

Boomer, Did you have any luck finding more info about the nylon insulators?

 

[boomer2506]

No I know the manufacture is winzer but cant find them on the web site.I think the rep comes on Tuesday
As soon as I see him I will get you guys the info on them.

 

[boomer2506]

Sorry guys and girls they have been discontinued. Bummer have to find something new.
