Best way to crimp bullet connectors?

I'm not sure I understand that one crimping tool that says it crimps in a hexagon pattern?

What would be the purpose of that kind of crimp?

Stronger perhaps, I've never seen one and wonder if they require special connectors to be used with them.
 
Often over looked in making up wire connectors is the failure to make a mechanical connection to the insulation. Quality connectors will have a collar or other means to secure the connector to the insulation. The purpose is to improve the mechanical connection to minimize the flexing of the wire at the point where the solder ends and the unsupported wire strands begin.

You will note in the following image there are two points of connection. On the right is the electrical connection to the wire which is either soldered or crimped. On the left is a second crimp connection to the insulation.

Here is another connector, showing the two connection points.

Here is a shot of connectors that do not have the second mechanical support crimp.

All these connectors require shrink tubing for insulation, and the last one for mechanical support.

Other then for quick repairs, I stay away from these because of the poor mechanical support. When I do have to use them for long term repairs, I remove the insulation, solder, then use shrink tubing.

Hi guys - do you try to get solder into the end of the bullet connector or just on the wire/bullet connector where it attaches?

EDIT - looks like the correct way is to get the bullet connector hot, fill it with solder, keep it hot, and then stick the wire in it and let it cool. Yes?

----NO!!!
Make sure the wire is clean then tin it. Poke it through the hole in the end of the bullet trim it close add additional solder there using a good hot Iron and capillary action will complete the connection.---Keoke
 
a crimp is the best way, if your soldered joint get hot because of a short the solder melts and the wire comes out, soldering speaker wires is fine but I would crip all bullet on the wires if possible

If the solder in a bullet connector in an LBC gets hot enuff to MELT due to a short, you probably have bigger issues. :devilgrin:
 
The problem I have with soldering the wires is when you solder multi strand wire; it becomes a sold strand wire and will tend to break easier. The shrink wrap would tend to spread the stress across a greater area and reduce the problem. Also you would want to limit the amount of solder that is pulled into the wire beyond the connnector.

If your wiring gets hot enough to melt the solder, then its on a
British car for sure.
 
I got it Tom, was that person asleep the whole time?
