But you really need a good ratcheting crimp tool with the proper dies to achieve one, especially with those insulated crimp connectors. The common, pliers-like ones, with the half round recesses don't work well, if at all. And those are what people who don't often have a need to crimp usually end up working with. I'd trust solder before a crimp made with one of those. Crimp or solder, relief is necessary, as both create a natural flexure point where the wire can fatigue. Electrical tape should be enough, unless the wire is subject to repeated bending (more than simple vibration). |
