Power connections

Power connections

2004-03-20 by z_flash_ram

Hi,

I'm ready to go to the next level and I need a source to either build
or buy standard MOTM/CGS power "wires" (+15,0,0,-15) that connect
from my MOTM power distribution board to the individual modules.

If anyone suggests a DIY approach, what guage of wire and what is
the "female" part that would be attached? Any part #'s would be cool.

Thanks for any help or direction, I'm getting close.

Chris

MOTM uses: (Mouser#)

The wire is 18 AWG
571-6404264 AMP MTA .156 Plug
571-6405514 AMP MTA .156 Dust Cover

I would suggest buying this to punch the wires into the pins.

Hi,
The wire I ordered from Mouser recently are part numbers:

Mouser# 566-9918-100-02
18AWG UL1007 RED

Mouser# 566-9918-100-09
18AWG UL1007 WHT

Mouser# 566-9918-100-10
18AWG UL1007 BLK

Each of these 100ft. rolls was $18.75 ea. and seems to be identical to the
wire that is used in the MOTM power cables. Just be very careful when attaching
the wires to the MTA connectors. It's very easy to accidentally injure
yourself with whatever tool you are using to press the wire into the connector. This
last go around, I used a vise to press the wire ends into the connector. It
was still difficult, but it was a lot safer (imo).

Unicorn Electronics (www.unicornelex.com) has 100ft rolls of 18ga at
$7.85.

I've tried a few 100ft. rolls in this price range (Mouser and Digikey have
them as well), but the insulation thickness didn't match up to the MTA-156
connector very well. The MTA156 connector accepts 18AWG wire, with .095" (2.41mm)
insulation.

Thanks for all the info, Mouser made another sale.

Ok, I received the MTA156 connectors/dust covers and the 18AWG from
Mouser- I also bought the plastic $22 "tool" to aid in stuffing the
wire into the plug.
A first attempt, I stripped an end of wire, twisted it a bit, and was
able to place it (by hand) into an MTA slot fairly easily - a little
snug, though can be easily removed.
Is this all there is to it? How much of the wire do you usually
strip to place in the "slot"?

Thanks for all the help, I've only seen these Pconn wire setups over
the internet, not in person.

You do not strip any of the insulation. Place the wire into the connection
until it butts up against the far side, and the punch it down with the
tool. The sharp edges on the "fork" cut through the insulation and make
the connection. The is the same technique used for phone, ethernet, and
other comunications applications.

Hi,
I'm not sure how everyone else is doing it, but with the last rolls of wire
I bought (which seemed to be the proper fit for the MTA-156), I didn't strip
the wire at all. I think the insulation serves as sort of a minimal strain
relief, and also helps to keep the wire in place.

Previously, with smaller gauge wire that I used, I soldered the wire into
the connector to be sure of a good electrical and physical connections. It's
difficult to do this though without melting the connector.

Hope that helps,
Andrew

Right Andrew. The right gauge wire for the connector should not be
stripped at all. I agree.
