Wiring Harness Crimping

[toger13]

Not sure if this is the correct section but I am about to start making an engine wiring loom, most of my conectors on the engine sensors are junior timer and junior power timer conections.

I made a loom for this vehicle about 5 years ago and used a cheapo crimiping tool and I had to remove the loom and solder all the conections as they wernt up to scratch so this time I want to do the job properly and want to buy a decent ratcheting crimping tool

I have recently used one that held the pin in a plastic housing and it was just a case of putting the seal on the wire and holding it in the correct place I was very impressed with the ease speed and the factory look of it

I have been looking for somthing like this but there is just a sea of crimpers from 30 quid to 1000`s and have no idea where to start

Can anyone recomend me anything?

Thanks

Tools are often very specific to the connector type, I made harnesses in my previous job and had about 15 tools at my disposal for as many (if not fewer) connector types.

I've never heard of junior connectors, do you have a link to them as that will help!

These are the ones but they are quite readily available

If you get your hands on a durite catalog they have crimpers and terminals and all sorts of usefull bits www.durite.co.uk

From your link.. http://www.vehicle-wiring-products.eu/VWP-onlinest...

I don't understand what you're saying about putting seals on wires in your original post? But for the terminals in your link a non insulated crimping tool is what you need.

Personally I always solder as well. People say that soldering is wrong but I've never had any problems, people say a lot of things.

They use seals like these but generally if you solder them aswell as crimping it distorts the seals

If you want your harness to be properly robust and long term durable, you shouldn't be taking a soldering iron anywhere near those connectors!

Ye after seeing what happened when I soldered the last one that's why I want to do it properly this time

Thanks

After looking for some crimpers for non insulated terminals I bought a set of these :-

I am shocked at how well they work despite the cheapness and the fact they are from China.
Looking at the JPT connectors I have here it looks like it will do them no problem.

I'm with ya now, but I don't think you're meant to crimp the seals. The seals are obviously put over the wire & can be pushed into the box after the terminal has been clicked into place. So basically you can still solder if you wish to.

I crimp the pin then slide the seal in after the pin is inserted into the housing. I have seen professionally made wiring where the seal is included in the crimp. With the seal done in this way I find it very difficult to 'feel' that the pin has correctly latched into the housing. You can spend many an hour trying to fault find a circuit only to find a pin pushed back in a connector.

Right I will give some of them jpt specific ones and see how I get on
