Posted: Thu Jan 11, 2007 7:47 am Post subject: Secure connection to a diode?

Hi all,  

   

I’ve got 3 individual diodes that have to be wired between micro switches and pin connectors and the gear switch and valves with fast-ons, etc.  How do you connect the ends coming out of each side of the diode to 20 AWG wire?  Is there a connector out there for that?  Two of the diodes have multiple (2) connections on each end.  

   

Needless to say…I’m a wiring newbie!  

   

Thanks,  

Jon Hults

When I have multiple wires at one Faston connection, I use the

appropriate (bigger) size and put both (or all 3) wires in the connector

and crimp them all together.  B&C does that for the diodes they install

on their contactors, so I figured it must be OK.  I think Bob even has a

cartoon on how to do that on his website.



If the pin connectors are big enough (i.e. Molex) you could do that as

well, but D-Sub size pins are too small - you'd have to join the wires

with a faston size splice with the multiple wires in one end and a

single wire (maybe doubled over) out to the pin.



If for some reason you want to be able to separate them, you can get

faston 'spiders' at the auto store that have 2 male tabs and one female.

That's a less-robust solution IMHO.  I personally wouldn't go that route

on gear switches.



And if all else fails, there is always solder...

Hi all,



I've got 3 individual diodes that have to be wired between micro

switches

and pin connectors and the gear switch and valves with fast-ons, etc.

How

do you connect the ends coming out of each side of the diode to 20 AWG

wire?

Is there a connector out there for that?  Two of the diodes have

multiple

(2) connections on each end.



Needless to say.I'm a wiring newbie!



Thanks,



Jon Hults

    Yes. See . . .

    I've not had very good luck with multiple wires into

    anything except the old MS3100 series solder-pot connectors.

    Crimping multiple wires into connector pins is problematic.

    Jon it's not clear from your text as to the exact

    nature of your task. Can you scan a sketch of the wiring

    diagram and attach it to a reply? I 'think' I know

    what you're dealing with but a schematic would help

    me be more specific and useful.

Bob,  

   

I don’t have a schematic or wiring diagram.  The application is a gear door sequencing system with a control box, gear switch, 10 micro switches, 4 electrically controlled hydraulic valves and three diodes (1N5400, I think).  All I got was a written description of how to wire all components.  All wires are 20 AWG except power and ground.  

   

Diode A:  Gear micro switch & control box pin 12---(diode)---gear switch & hyd valve A  

Diode B:  Gear micro switch & control box pin 15---(diode)---gear switch & hyd valve B  

Diode C:  Control box pin 2---(diode)---hyd valve D  

   

So how do I connect the diode leads in line to 20 AWG wire securely?    

   

I was wondering if there was a connector of some sort for that kind of application or if I should, as Bill Schlatterer suggested, solder them and then cover with two layers of heat shrink.  His look really nice!  

   

Thanks Bob,  

Jon Hults

     I'll publish a comic book on this later

     today.
