To crimp or solder

Be careful, I only use the insulated ones in shown above, if you're using the non insulated ones you'll need the right crimped, although it may be cheaper to buy insulated crimps now, and cut the plastic off after you've crimped them

I'm not familiar with what is available over there, but here we have connectors with the same type of "crimp area".

The business end can be open, closed (ring), or a male or female "spade" (in 3 different sizes), bullet, and splice are the ones I can think of off the top of my head (and I have here)

In the use, there are usually 3 basic sizes for wire gauge, color coded to red, blue, yellow (small to large wire gauge)

The crimp I use basically punctures the center (not on the split side) and compresses it.

The cheap crimpers just smash these into an oval, very poor, the wires will slip out.

There is a specific tool with a "finger" that adds pressure to the crimp, but more importantly "locks" wires from pulling out.... see the "indent here"

Yep, that crimp tool will overcome the issues where the cable size does not precisely match the wire gauge.

I've successfully crimped wires (for applications other than garden railways) without that extra indent - but it does rely on the wire gauge being a close fit inside the chosen colour of crimp connector.

The indent make is possible to use a slightly oversize crimp connector.

And yes, we have the same options of crimp connectors, but for the fact, certainly in the red size, I now have three different sizes of spade - male / female - connectors.

2mm, 4mm and 6mm I think

So the crimper and connections are a little different, JST (Japanese Solderless Technology), the link below is to just one of the many out there:

There's 101 ways of killing a cat :rock::rock:

I think the key thing is using the appropriate method for the situation - and we'll all have our favourites; a bit like the question of electrical track connections.

With a bit of luck we won't have confused our friend too much, even if we end up confusing ourselves :oops::oops::oops:

I'm just in the middle of doing some minor wiring for the car, so I've been busy soldering crimped tags :whew: as the water / damp issues are similar.
 
Yes Jimmy, you can really go overboard when you start using more sophisticated crimps, like most in the electronics industry, where you actually have 2 crimps per connector, one on the insulation and one on the wire.

I have about 6 crimping tools personally, and for the above mentioned crimps, you need a crimper to the EXACT size needed. To me the crimps look like a little "w". We have these at work (I run a small engineering company) and we buy the professional tools where the crimper usually exceeds $100.

But normally in this hobby, this kind of connector can be purchased with the wire already attached.

Ahh, that's the "extra cost" option, used for autoreversing in DCC ! :D

Really cheap, actually..

When pointed out to the seller, they made and sent 100 pairs wired the exact opposite to those above. - No charge!

An excellent result, from where I was sitting. :):nod:

Greg, as said earlier I use the crimps for loco work (with JST-XH connectors) and solder for track work, and again you are quite correct about prices, I paid around £20.00 for my crimps which is cheap, but they do work, looking at what "seems" like similar crimps from a professional organization - £400.00
 
Hello all
I posted the first question on crimp or solder. The reply’s have certainly provided a wealth of opinions and knowledge. Thanks to everyone who took the time to answer my question.
