Posted: Thu Mar 13, 2014 1:47 pm Post subject: spliting 2 wires at a dsub connector

In the sprit of the comic books that Bob has  put together which have proven so valuable

I need to split a shielded wire into 2 pins on on a DSUB. I am sure that what I did would be an acceptable approach but is there a better way?

this is a 2 conductor shielded wire. I have already added a pigtail using a solder sleeve

thanks for the help





I striped off a 1/4 inch strip of insulation about 1 1/2 inches back from the pin

following Bob’s comic book on splicing wires i teased out a couple of strands of the wire to be joined

Wrapped and soldered

added shrink wrap and crimped on the pin

Thatâ€™s a perfectly acceptable way to do it; I have used that method many times without any problems.

For frequencies above about a MHz, this shouldn't be done, since the insulation itself carries the signal. See attached.



By the way. I ran across a paper that recommended wire-nuts for connecting multiple wires. Is there some reason not to do this?

        The main reason that I could see is the

        added bulk of the wire nuts might make

        it difficult to impossible to add a cover

        to the connector.

    I'd like to see the physics of this explained.

    Yes, there is a skin-effect that pushes the current

    flow to the surface of the conductor

    . . . but carried on the insulation?

    Wire nuts? Like this?
