But if you are making this for a pre-existing system then you have to make do with what you've got.. @rdtsc I would not recommend that approach, using both does not make the joint twice as good, but could easily compromise it instead.. One of the most common failure modes of these types of crimp terminals is that if the terminal is too stiff at the crimp then the wire breakes just above the crimp. In partic-ular, this method leaves some element wires out of contact with the serration in the terminal and hence increases the contact resistance of the electric wire, as shown in Fig. No it is definitely not the approach I would recommend. What was the last non-monolithic CPU to come to market? Inkscape: fill object without filling inner object. The pins are very sensitive to proper crimping.

The word “crimping” in regards to this context implies making a joint between two wires by deforming them to hold on to each other. The whole idea behind stranded wire and crimp connectors is that the wire can micro-flex in the micro-inches against the pressure point where nothing moves. I would then use a 18-24 AWG crimp terminal; which should be OK if it was a single-conductor cable. Thus, the word crimp. Crashbloat. @Andrew Yes if you absolutely have to connect 3 wires to one mini-fit terminal then a Solder splice is the proper way to do it.. That said I have used mini-fit and similar connectors a lot and what I have often done in this situation is to just use a connector with more terminals and connect one wire to each terminal, then just short those connections on the pcb.. ⎯ removable contacts, single wires ⎯ removable contacts, multiple wires ⎯ coaxial connectors, ferrules ⎯ lugs and splices.
