WotEver Posted January 22, 2018 Report Share Posted January 22, 2018 Hi all. Anyone know a UK supplier of 2 into 1 crimp connectors with adhesive lined heat shrink? For 1mm2 cable. Google isn’t helping much. Thanks, Tony Link to comment Share on other sites More sharing options...
NMEA Posted January 22, 2018 Report Share Posted January 22, 2018 Do you mean Piggy back spades, but splices or something else? Link to comment Share on other sites More sharing options...
p6rob Posted January 22, 2018 Report Share Posted January 22, 2018 Not sure I understand what you're looking for but try these: https://www.autoelectricsupplies.co.uk/. I've managed to get quite a few obscure electrical connectors from them. Link to comment Share on other sites More sharing options...
Tony Brooks Posted January 22, 2018 Report Share Posted January 22, 2018 Not what you asked but what about the old bullet connectors with a twin receptacle. Then you could use ordinary crimp on bullets with adhesive sleeves. (Asd used on old car lighting circuits). Link to comment Share on other sites More sharing options...

A butt splice but with a double entry on one end. Basically I need to splice into a few wires that already terminate in multipin plugs. So I’m trying to find a professional way of creating a waterproof (or at least corrosion resistant) three-way connection. 37 minutes ago, Tony Brooks said: Not what you asked but what about the old bullet connectors with a twin receptacle.

philjw Posted January 22, 2018 Report Share Posted January 22, 2018 Have you seen these? https://www.ebay.co.uk/itm/New-Quick-Splice-Lock-Wire-Terminals-Connectors-Electrical-Crimp-Cable-Snap/252295874219?epid=2061799778&hash=item3abe0186ab:m:mvaeVvG9coypm-_cRNNTDXQ They look a bit better than standard scotchlok but not too waterproof. Some self amalgamating tape would help with that. I have used the double bullets which Tony suggested in the same circumstances. Link to comment Share on other sites More sharing options...

NMEA Posted January 22, 2018 Report Share Posted January 22, 2018 Fully tinned Japanese Y bullets would do you perfectly, corrosion resistant and demountable. They have proper ads cheek crisps for secure strain relief and separate insulating boots. If you Google Y bullet terminals it should bring some up.

One "gotcha" with this I found is that the crimp bullets can be different sizes depending on the colour code. I got some from Vehicle Wiring Products, and found the blue ones were the same size as the solder ones, the red ones were smaller and the yellow ones larger.

Tony Brooks Posted January 22, 2018 Report Share Posted January 22, 2018 I know the Jap type have smaller diameter and a different shape but not that the UK types were different. Probably makes sense because they are supposed to mate with a female version. However those old mid-sections may well unroll enough to get a larger bullet in.

Does this listing looking like the kind of quality you’d look for?

Chewbacka Posted January 22, 2018 Report Share Posted January 22, 2018 (edited) I had the same problem a few years back and put two wires together into one end of a crimp, so far no problems, though I agree it is not best practice and not something I would do on a salty water boat. Since then I use Wago connectors in a few locations. As an aside I use the 3 port Wago connectors for connecting pumps etc, that way if/when the pump packs up it's quick and easy to change. The reason for the 3rd port? the multimeter probe goes in there if ever fault finding. Added - when criming I never twist the two wires together, as twisting is bad.

It is verboten. I knew a QC chap who not only confirmed no twist on the strands but would use a small pick and with the aid of a jeweller’s loup would count the strands sticking out the end of the terminal. If it was one short he’d condemn that wireman’s output for the day. Link to comment Share on other sites More sharing options...

Chewbacka Posted January 22, 2018 Report Share Posted January 22, 2018 Certainly 20 years ago car looms would use solder for a splice - don't know if they still do - the 'main' wire was not cut but stripped back and the splice wire gently wrapped around and then soldered. The splice wire was then firmly taped to the main wire to keep stress away from the solder and the whole bundle put into a conduit. Link to comment Share on other sites More sharing options...

An awful lot of vehicle manufacturers will not allow soldering nowadays. The recommended method, which then retains the warranty, is adhesive lined crimps.

Sorry I was not clear, I was not talking about after market, but designed that way by the vehicle manufacturer, they were buried 'deep' in the loom, so not obvious.

Perhaps I wasn't clear either, many manufacturers of the 90s used crimps to join wires together. I repaired enough of them. The aftermarket thing was to show current thinking.

I’ve decided to go the bullet route; I like that it’s demountable too. Link to comment Share on other sites More sharing options...
