Flat power cable

[hrishi11]

Hi there, I am not an electrical engineer but thought I would ask to see if an electrical engineer can give some advice. I am looking to run a power cable through a small 2 millimeter (mm) crack between two glass windows. But because the head of cable is larger than 2mm, I obviously can't run it through the 2mm crack.Can someone provide advice on how this can be done? As I have access to both sides of the glass, I was hoping to run a thin connector through the 2mm crack and have it connect to the rest of the cable after it passes this gap. Keep in mind that I don't have access to the top or bottom of the crack either, so i can't run the middle cable through the top of the glass crack. It would strictly be passing through this 2mm gap.

Could you please advise?

Thanks

The obvious questions are:
How much power?
What voltage?
What current is the circuit fused for?
What is the likely load current?

This will probably not pass code. The implications are that the installation may void your insurance policy.
Temporary cables are not to be installed permanently.

Hi Mike, while i don't have the exact specs for power, its basically a 15.4" laptop that needs to be plugged in. The voltage is 110V. I am not sure about the circuit fuse or load current either unfortunately. Would you still be able to suggest something?

Thanks

Buy a spare battery for the laptop and an external charger for it. Swap the batteries.
OR
Buy a couple of 12V jumper cable 'juice boxes' (on sale at HF for ~$40), and a DC adapter for the laptop, and swap the juice boxes.
AND
Caulk the crack.

Is this a 2mm hole, or a 2mm wide slot of indeterminate length? If it is a slot have you considered using a double-sided printed circuit board?

Send the cord-wart low voltage out the window.

Convert to solar and keep all the power outside. Or put a solar panel up against the window and a bright focused light on the other side of the window.

Thanks Mike, Scott, and Keith for your responses. The laptop will be outside the store and the power would be inside the store. Unfortunately, because it's an indoor environment, a solar panel wouldn't look good in a store front. Just to give you an idea of the size of the crack, I have attached a pic. As you can imagine, the crack in the glass is closed from the top and the bottom, so I can't slot it through either end (see pic).

The electrical inspector won't like it...

I'm surprised you can't get the low voltage side of the power to the laptop thru that crack. All my laptop low voltage cables look like they'd fit. Of course you'd need to cut it, feed it thru, and re-splice it but they'd fit.
