Need help w/ circuit board/connections

[Josh]

First off, it’s really annoying how when I copy and paste something here, even if I remove formatting in Word, it has all these formatting notations in my text… that being out of the way, and me having spent the time to clean this up, here you go. 🙂

 

So I have a Variable Frequency Drive that runs several motors (individually, not at the same time). In the picture below, you will see a bunch of red jumpers on a circuit board, one of those is going horizontal, the one below where it says “CL”. Where that jumper is there are a total of 10 pins, each measuring .025″ in diameter. I want to connect 22 gauge wire to each of those pins individually and run them out of my vfd to a remote rotary switch. The connectors I need will have to crimp/solder onto the wire, and then the other side of the connector will be female and slide down over the male pin and be a good fit. Any idea of what types of connectors these are an where I would get them?

* for those interested in what this is doing, basically the jumper connects each set of pins to enable you to run 5 different horse power rated motors – 2, 1.5, 1, 3/4, and 1/2 HP. So my rotary switch will allow me to change the HP rating for whatever motor I’m using on the fly instead of having to open up this box and manually change the jumper.

Thanks for any and all help

 

I already have the wire, I just need the connectors. It will look like this (as I am sure you are well aware =)

 

More close ups of what I’m looking for but don’t know what they’re called…

Here is a pic of the wire I was going to use… I got it from mcmaster carr High-Voltage Continuous-Flex Flat Cable. You think the signal would travel the 10 ft to and 10ft from ok? Is there a way to measure it w/ a meter to see if it would be strong enough?

Josh,

I believe what you are looking for is called Molex pins. Radio Shack should have them

Are these it?

Do an ebay search for:

Dupont Jumper Wire

You will find the connectors both female and male as well as the housings very reasonably priced. If you buy the housings long, you can cut them shorter for a custom fit. The Arduino community uses these extensively.

Try copying your word document into something like notepad that uses plain text and then copying the plain text to paste into this forum; it will save a lot of editing out formatting symbols.

Very cool of you guys!!! Thank so much for the help! The Molex pins appear to be the ticket, but I just want the bare metal ones I believe (not sure how much clearance I have for between the pins). These appear to fit the ticket! Now I know I have 22 awg wire that will be going to these connectors, but how do I know how to match the pin size (.025″ thick) to the female crimp pins? They don’t appear to list in the descriptions what size pins the connectors will fit… I guess I will be taking a trip by radio shack!

 

* also, do you think this signal can transmit 10 ft to and from the box where the rotary switch will be?

I thought that Radio Shack went belly up this last year.  Newark Electronics might be an alternate source.

They closed a ton of stores but some stayed open, they just went though a major down sizing is my understanding.

Thanks for the alternate source!
