Short Julet extension cables.

[StuartsProjects]

I would like to get hold of sone short, 40cm maybe 50cm, Julet extension cables.

There are plenty of the Julet extension cables on AliExpress, but the ones I can find are all 80cm long.

I would like;

2 x Blue, 4 pin.
2 x Orange, 3 pin.

Of course I could use the longer ones, but if the shorter ones are avaialble I would prefer to use those, it makes for a tidier install.

Why not cut, solder (I know you can solder well, from your advice in a previous thread) and join with self adhesive marine 4:1 heat shrink? The adhesive is a thin layer of some kind of hot glue, therefore the result can be a little stiff, but the sleeving is flexible till it cools. I used this stuff recently, which is shrinkier than the avergae heat shrink. Usefully, it starts wide enough to slip over most connectors:

Its high shrink ratio makes it ideal for sealing large components and irregular shapes. NOT the lay flat width of the heat shrink. As a guide, the lay-flat width of our heat shrink is below Shrink Temperature: 90 °c.

I had a similar problem some time ago. ended up buying the longer ones and cutting them in the middle, shortening to required length and re-soldered each wire with shrink wrap over each, then a larger shrink wrap over the whole cable.
Other, cheaper option is to loop the excess cable and tie-wrap it to the bars or another part of the frame.

I had considered cutting and splicing, got plenty of heat shrink here, some of the hot melt glue stuff as well. Not so tidy a solution, although the join could be just inside the controller bag and hidden.

I have since discovered that 20cm Julet extension cables are available from Swytch @ £15 each, so using these would cost me £120.

Every ugly cut and soldered joint of mine is hidden away behind webbing, which also helps reduce the possible breaking strain over time, which might be exerted by tight zipties securing cables containing delicate thin wires to the frame. Handy obscuring material, is that PC cable webbing - I've got multiple cables running through some of them, which would be an eyesore without it.

Its just a tidy up of an existing install, currently using 80cm cables, I would use 40cm if I could buy them hence the question.

I have no intention of using the (somewhat expensive) Swtch cables, just posted the info to show that shorter ones do appear to be made.
