3 connectors to one

gadu^ · 02-28-2007, 09:02 AM

I'm thinking of building an connector adaptor.
My TS has three wires; power, vga and usb.
So the plan is to get some sort of multi connector that's able handle all three of them. Reason for this is that I need to remove the TS from sight when leaving the car. To disconnect three connectors takes some time.

No problem soldering, been doing that in the past alot...

Any recommendations?

I was first thinking of a scart connector (male and female ofcuz), but that probably won't work with VGA right? But something similar maybe?
If I remember correctly I need something with 14-18pins .

I've been using the CPC connectors from AMP/Tyco on my CNC machine and on my carpc with really good results. I'm not sure how much it's going to affect your VGA signal though since i've mostly used them for serial and power. The default connector that comes with the lilliputs is a cheap DIN connector so I would imagine as long as your cables arent 30ft long it should work fine.

You might try a 25-pin DSUB (same as the parallel port ont he back of your PC).
Cables are readily available and somewhat cheap.

Figure VGA = 15 pins
1 USB port = 4 pins
Power = 2 pins

That's 21 pins, and a parallel has 25. Add another USB port, maybe?

my last TS monitor came with a special vga plug. it looked just like a bog standard vga connector, but the spare pins must have been converted to carry power, vga, usb and composite. it was the only connector on the screen its self.

i dont know the makeup of a standard vga cable, but if there's enough free pins then i'm sure you could do this.

edit: my old screen was a tm-868

I thought VGA only actually used 5 or 6 wires... something like R, G, B, V-Sync, and GND...?

Maybe. I'm just saying that there are 15-pins in a standard VGA connector, not counitng the ones that were actually USED.

DSub connectors work great but with repeated connects and disconnects i've had them loosen up and stop making good contact. It's usually not an issue with PC's because you connect the DSub once and don't disconnect it often.

Just a thought...

True idd... The VGA on my cable don't use more than 5-6 wires.
I have given DSub's a thought as well, but i connect and remove the TS at least once a day so the Dsub would wear out pretty quick. Not to mention that they're usually a ***** to solder... I've been looking for similar connector as jcdillin has a pic of. The closest I've got was a radioshack who sold over priced military connectors around 300SEK (~$45) for each end. Not an option.

But whats your experience, any connector might work as long as it's short distances?

check out tyco. they have some pretty slick and easy to solder connectors that use a positive locking system on the contacts so they'll never wiggle loose. We use them on our golf cars for all the signal wiring and some low-power wires too. I'll see if i can get you an mfr p/n

they arent the cheapest but jameco has all the CPC line.

Well, I checked Jameco and started to order until I found out that shipping would cost me $60 to Sweden for $20 worth of connectors...
