Strain relief for 24awg wires

[hk_jh]

I'm working on a project that uses 24awg wires. Has people will pull the wires I will need some kind of strain relief for that cable. I have bought those connector sockets but the 24awg (0.5mm diameter) is too small to those sockets (wire diameter recommended between 4mm to 1mm)

I was wandering if there is other solution for that?
Maybe there is smaller terminal connectors?
what about glowing the wire to a peace of strong material so it will act like a strain relief ?
Maybe there is something like this that is suitable for 24awg wires?

Thanks again!

buy smaller sockets

Show some photos.

I usually drill small holes at the end of the board and pass the cables through there first.

Other than that, some sparingly placed hot glue works well.

Easy to remove also if the need arises.

What’s the objective?

The wire breaks, or pulls out of the socket… or ?

What’s the breaking rating of your wire ?

If it’s not meant to snap, you may need a more complex arrangement to take up any force.

I'm guessing the big concern is that the wire will be pull too strong out of their screw terminals.

Here is the wire I'm using 24awg -

those wires will be connected at the far end to those screened terminals connectors(upper board):

Those two boards will be hang from above the ground around 7-10 meters so the wire will be at the ground level and people will be pressing it. It might happen that people will try and push the wire/sensors therefore I'll need to make it strong at the board side up above. I was suggested to use terminal blocks but the only one I have found are too big to the 24awg wires.
Therefore I'm asking if there is other solution?

[bluejets]

Yes, ....at the risk of repeating myself........drill holes in the edges and pass wire through that first.

Make holes only large enough for each conductor.

[lastchancename]

Yep, agree with @bluejets
In the first post, I read-in that people will be pulling the wires.

If that’s not the case, the solution is literally as simple as tying off the wires.

For termination, those barrier strips are less than desirable. There are hundreds of choices for small gauge connectors.

As you can see in the picture the board that will contain the wires have no space for drilling 16 holes for the 16 wires/sensors.
Can I drill 16 holes to a piece of wood and pass the wires to those holes then glue it?

@bluejets

Easy to remove also if the need arises.

How does is easy to remove if I will hot glue the wires in the holes?

people should not pull . but you can't really predict how people behave

@lastchancename

Maybe that one ?
Can you recommend me one from amazon?

[hk_jh]

What about using tie cables?
I have try the following:
When I pull the wire part marked in blue it has no effect on the wire part marked in green (the part of the wire that will connect to the screw terminals.

If this 7m wire is hanging unsupported, you've got a problem, but if it's supported by any form of mast or post, strap it to that? I think you're making this harder than it needs to be.
Otherwise, can't the wire be glued or tied to whatever is supporting the panel?

[camsysca]

@hk_jh

Or is that what you meant here? If "glowing" is "gluing", then yes, hot-glue it to supporting structure. If you need to remove it down the road, gentle heating with a hot air gun or hair dryer will soften the glue if you're careful.

[cedarlakeinstruments]

The problem, which everyone seems to be ignoring, is that you are using the wires for physical support of the board. Don't do that!

Use a string, or cable or something to support the board and then you can run the wire in parallel to it, or around it, or something, with enough slack that it will never be under tension. But the wire itself should not be what is providing support.

I'm sorry did not explain myself fully. the boards you see in the picture and that the wires will be attached to will be sitting inside a partly open box (looking like a cage from metal bars).

If you can do that search "stud mount cable tie".

[hk_jh]

ok seems good! so the tie cable is suitable way for strain relief a cable.

[JohnRob]

I usually either tie a not in the wires or wrap them around a zip ty or wrap them around an internal mounting screw (with a zip tie)

These will not however protect the wire from continuous flexing, that can easily break wire. Especially if its solid.

a question I had for time now - those it matter for the flow of data/signal in the wire if the wire itself is tie/turned over ? in comparison to a loose straight line of wire ?

[JohnRob]

No. For data or signal you would have to actually cut the wires to make a difference.

BTW

Use silicone insulated wires.

These are very flexible.

The strand count is large, 24AWG has 40 strands.

Add a second outer shroud if it is absolutely necessary.

I have those silicone wires

is this what you mean?

@LarryD

What do you mean by that?
