Good connector for removable power cable?
« on: Wed, 06 January 2021, 21:05:27 »
Hi all - I just found an old dremel that has a non-detachable power cable. I'd like to but a break in the cable and add a connector so that I can easily detach the power cable for storage. Should be something sturdy, maybe with threads. Any recommendations?

Don't do it.
"Starting in 2011, the deficits again started to shrink. During Obama’s term  the deficit was reduced by $900 Billion  before finally in 2015 the GOP managed to wrangle a “reconciliation” bill out of Obama where he again cut corporate taxes, as well as made permanent some of George W. Bush’s original tax cuts. This is the year everything reversed. Before this, under Clinton, Bush and Obama the deficit in almost every year was gradually decreasing. The balance we had of taxes and the economy was bringing the deficit down, the money coming in was slowly catching up with the money going out until 2015. Trump’s subsequent tax cut has continued the new trend even after the rest of Bush’s cuts have since expired. Obama had an average GDP of 2.3%, with 11.6 million jobs created and unemployment peaking at 10% in 2009, then falling to 4.3% in 2016. If we had continued on that downward deficit track, we would have again reached balance and another surplus in 2017-2018.

Connectors on cords that move around a lot do last long.
You can do it, but don't be surprised if the connector goes bad extremely fast. On 3d printers hot end connectors fail ALL. THE. DAMN. TIME. I hard wire them them right from the start these days. Cars have the same issue, that's why all those connectors are strapped down, double clipped and secured. Same for aircraft, you don't leave connectors dangling and flopping around. It doesn't matter how good that connector is, it will not stand up.

These are good points, but many people use power tools on simple extension cords all the time, and those are fairly rugged. Also, on that type of connection, the female side is more likely to fail, but is easy to replace. Plus, a connector for this really doesn't need to be certified for thousands of hours of fly-time or drive-time.

well if you really want to and your dremel is a low voltage model, a simple barrel jack would do, with a lot of strain relief so it can last more than a week of use, else the copper in the cable will fail right where is stop being supported. if it is the 110/220v versions, well, no do not do it, you will have to have a rather bulky connector that will make your life harder than needs be, or do but get a connector rated for the voltage you use, and up to your country's standards.

And they come unplugged all the time unless the part where the plug is sitting stationary/on the ground. They use the cord to get there roughly where they need to be, just like using your Dremel with an extension.

My guess is you don't want that connector down at the end of the cord you want it near the handle which is always moving. Otherwise just use an extension cord.

Absolutely not meant to be on a moving cord.
These are built to go from a stationary wall, to a stationary power supply.

No one puts a connector on the end of a moving cord unless they have to, it's just bad engineering.
