Butt connectors and heat shrink is the route I'd go. Soldering the butt connectors in is the best way to do it.
The main uses for a heat shrink wrap is the wrapping and storage of equipment including boats, bridges and food packaging. There are endless uses for heat shrink wrap.
All types of end to end wire connectors have to be crimped. Depending on what the environment the splice is to be used in, a second step is to put a heat shrink over the splice. The heat shrink will keep any moisture out of the splice.
Either replace the whole wiring harness, or repair them with some crimping butt connectors. Figure out the gauge of wire, get the appropriate butt connectors for it (the ones with the heat shrink are the best kind), strip the ends of both wires, insert the stripped ends into the butt connectors, crimp the butt connectors, heat shrink them, then wrap them in electrical tape to protect them.
Some of the cable accessories are chain form terminal,loose terminals, connectors and housings, heat shrink tubing , crimping tools and xb components.
Solder the wires together and use heat shrink to insulate the soldered connection. You can buy heat shrink at any auto parts store or hobby store.
If you're in the UK, I've seen them sold by www.cpc.co.uk - in fact I've bought them from there and I use a LOAD of crimps and H/S kit.
High Heat Porcelain Wire Connectors are very safe.
Heat shrink tunnels are used in shrink wrapping products. They are used to quickly shrink wrap all sides of a product at once, which is more efficient than using a heat gun and only shrinking one side at a time.
Cotton clothing can shrink if you use a high heat setting. To avoid shrinking, either select a lower setting or hang clothing and allow it to air dry.
Socks shrink in the dryer due to the combination of heat, water, and agitation. The heat causes the fibers to contract and tighten, resulting in the shrinkage of the fabric. To prevent shrinkage, it's best to air dry socks or use a lower heat setting in the dryer.
Heat shrink tubing was invented in the 1950s, in the later years, by Raychem Corporation. The head engineer founder was Paul Cook who used radiation chemistry to invent heat shrink tubing.
