Power cord strain relief bushing

[MaximRecoil]

My Missile Command has a strain relief bushing, similar to this one:

It is mounted in a steel plate that has a rectangular hole (rounded on two sides) in it. After you put the bushing on the cord, the bushing then snaps into the hole in the steel plate. Then the steel plate slides down into mounting brackets made from wood.

I have a couple Dynamo HS-1 cabinets, and they came with mounting plates for strain relief bushings, but that's all they came with. There are no strain relief bushings, and the plates are not mounted to anything (they are just dangling off the cords inside the cabinets).

This is what the plates in the Dynamo cabinets look like:

My question is: Where can I get strain relief bushings to fit that hole? I found them here for $0.75 each, but I don't know if those will fit the specific hole in the Dynamo plates. The sides look flat rather than rounded, so I doubt it.

These are a very standard item. I see no reason why this wouldn't fit. You should be able to find this item local to you. Fry's or local electric supply shop.

I see no reason why this wouldn't fit.

Because they are not all made for the same size/shape hole. For example, I found another place that had them, and they are made to fit in a 1/2" round hole (link). I need ones that fit the size/shape hole shown in the diagram I posted.

No such thing in my area. I have to buy everything electronics-related online, or drive an hour to find something "local".

I guess I should have said that the picture shown should fit without any problems. You can see that the sides are flat and the ends are rounded. These will snap in from the front side. I have used the ones pictured before.

Generally these strain reliefs were made by Heyco. They are made for different sizes and types of power cords. Some are made for flat cords while others are made for round cords.

The AWG size of the wire is important too.

Mouser Electronics sells most of the Heyco strain relief line:

I've bought them at my local hardware store.

unless its something rare/high end game i just tie a knot or two in the cord then feed it though, itll get to the knot and cant pull out further. If your im a commercial setting, then replacing the bushings properly is a good idea.

This is what I did on my pinball too. A better way to protect the powerbox than just the bushing.

I found some here. They came up in a Google search for "Heyco Strain Relief Bushes" (link - thanks Ken). I had to order 25 of them, but it only came to $7, and I guess I'll never need to buy any again ... EVER. I have two more machines that need them too, so that will leave me with 22 of them.

I got them today. They were a perfect fit for both my 18/3 round power cord, and the Dynamo mounting plate.

So what part # were they? And have you a source for the Atari plate that the cord passes through? Lately I've found a few Atari projects that are missing the entire power cords so I'm trying to find replacements.

Would this be the correct strain relief for a standard computer 18AWG cord for use in an Atari cabinet?

The ones I ordered, which were identical to an original one on my Atari Missile Command, were made by Richco Plastic Co., part number SRB-R-6. Here's a link.

Hmm Non stocked. I guess I'll have to wait for a plate to arrive before I can test these other Hyco's out.

There are other places that carry them. Just do a Google search for the part number. For example - link.

 

[Zinfer]

Going to try out what I'd bought but will refer back to this thread if it doesn't work out. Thanks.

 

[Fudd]

Zinfer was that the right part? I need to order some.

I had a problem with the transformer shortly after that post. Bought a diff transformer now, and spring is here, so I'll be checking out that strain relief if it would ever stop raining for more than just 1 day.

There were several recommendations earlier so I'll ignore those and say I recommend Mouser 836-1210 / Heyco 1210 (here).
