I need to repair a broken cable with four wires but there will be no option to solder. So I have to use a screw terminal to extend the cable. The broken cable looks like as follows:
And here is the screw terminal block:
The cable will be on the top of a bridge where there will be rain sometimes. So after I extend the cable by screw terminals I need to find a way to cover the extended section in a way that it wouldn't leak water.
So far I could only find such option as shown here http://www.littlegreenhouse.com/accessory/e-cord-cover.jpg But these are for AC cords I guess.
It is impossible to solder on the top of a bridge and it is long story. So soldering is not an option.
Is there a way to safely cover the terminal block with waterproof. Or any other option to extend with waterproof? Is there any component for such purpose?
