I have one of the older Orion Atlas EQ-G mounts.  Lately the scope has stopped slewing and shut down at random.  I believe (with the help of previous forum discussions) that I have narrowed it down to a loosening or twisting of the 12v barrel connector during slews.  This seems to be a fairly common scenario.  It's my understanding that the newer mounts have a screw down connector for this very purpose.

 

Right now I have electrical tape wrapped around the mount to secure the plug in place... total hack job.  Anyone have any ideas or success in a more elegant solution to hold that connector in place?

 

Thanks!

on the celestron cg5's, the panel mount connector has a split center pin.  often, I need to take a small pocket knife or very small screwdriver and insert it into the split to make the O.D. of the pin slightly bigger.  this works for a while to keep the connector from falling out during slews.  generally once a season.  not sure if the atlas mount is the same, but if it is, just open up the pin slightly.

I use a nylon cable clamp secured by one of the screws on the power panel to provide strain relief.

I replaced my 12v power cord with one that has a right angle connector, as it seems to create less stress on the plug.

A wider view for more context...I use Anderson Power Poles to make disconnecting easy for transport.  I also unplug from the mount during transport as well.

Unfortunately the Atlas connector is just a standard metal barrel.  I appreciate the response, though, and will keep this in mind should I come across a similar situation.

Thank you very much for this... that's a great idea.  I bet I could find a few more uses for cable clamps considering the current state of my cord management is... less than optimal.  I am actually using a right angle plug right now but it seems to still be working its way out or otherwise losing contact.  Mine may require a combination of cable clamps and something to hold forward pressure at the connection.  At the very least this will let me get by with less tape!

I purchased some decorator velcro (only one side is sticky), stuck a piece to the top of the mount and use a piece of the non-sticky to make an attach point for a loop of power cable. This relieves all strain on the plug.
