Splicing/joining ultra small guage wire

    Given the season that's in it we are currently putting up our Christmas decorations. In the process of putting our crib away last year and taking it out again this year we managed to damage a wire on some decorative lights we have around the crib.

    The wire is ultra small gauge and is measuring only 0.42mm diameter including whatever covering is on it. The lights are tiny LEDs linked in series and seem to be soldered to the wire (i.e. not removable like more traditional lights). They are powered by three AA batteries.

    Just wanted to see if it was possible or even feasible to repair these lights and how I would even begin to go about it??? I assume given the small gauge a connector is out of the question but I assume it should still be possible to solder them?? If I can solder them how do I strip back to cover on such a small gauge wire?

    The lights have sentimental value so it would be nice not to have to chuck them. Any advice or guidance would be appreciated.

    You could solder the connections.

    That’s what I was thinking. What would the best way be to strip it back before I solder it do you think?

    The little gel filled telephone line joiners would work, if you can find somewhere that stocks them! An electrical shop that supplies electricians would have them, or amazon if you can wait:

    I'd imagine most electrical suppliers would have them.
    I got some in National Electrical Wholesalers, Marino/Malahide Road, during the summer.

    I’ve seen those but never used them. Do I need to pare back the cable or is it just a case of inserting them as is and tightening?

    You push the cables in and then push down on the orange part which clamps the cable.

    Just insert the cable and squeeze the orange button with a set of pliers (or a hammer ;) )
