Concealed Power Supply

[Charlie_]

I need to get a 110v supply from a wall, through a door frame and into the glass rebate of a door..
Has anybody successfully done this?
I want it to be concealed so the little boxes with flexible conduit are no good.
I’m thinking of using power transfer hinges.
It’s to power smart glass in the door..
The windows are easy enough as they are all stationary.

there are so many types of transfer hinge. can you post a link?

Yes will try to.. The ones I’ve used previously are for elv supplies so struggling to find one avtually rated for 110v

there are loads of spring contacts out there but not suitable for 110v
you could transform 110 down to 30 outside the frame and then step back up inside the door but its a messy solution and the current at 30v might be higher than the contacts are rated at.

smart glass in a door???? beam me up scotty.

buy a mirrored door, sometimes the reflection will be smart?

Not got much room to play with inside the glass rebates..
The glass comes with 2 thin tails which I will twist,solder & heat shrink onto the supply legs..
The load is about 10 watts..
The other option I was thinking of was how to concertina the wires up in the frame rebate when the door closes

is the glass put in yet ?

No not yet..

something like this might sort you out.

No not yet

good ,the best way is to extend the cable through the metal frame to the transfomer .is the frame in yet .

That looks like a good and simple solution.
I shall investigate further

Timber door and frame..
Transformers located elsewhere..
I have wired supplies from transformer to door frame location

some times the smallest ideas are the best ideas ,wood you like me to send details to a beaver .lol.

the spec has no voltage limits listed. I am presuming it is just the conduit with no cable inside. but it also fails to list the internal diameter so its not a guaranteed fix but might be suitable.

Smart glass? Is that a pint one that fills itself

i'm lucky enough to have a wife who sorts the pesky filling operation. I deal with the emptying.
its a 50/50 split of workload (in my mind)

What smart door need 110v supply seems like a odd voltage for Uk application. Need a bit more detail/photos of planned install

or this, maybe only rated @ ELV though.
