Mechanical Connector for CO2 Laser Connection
Posted: Tue Apr 21, 2015 9:18 pmHi All:
When I got ready to hook my Laser Power Supply to the Laser Tube I discovered thru YouTube videos and Forum searches that most of the connection schemes were using alligator clips or fine wire to mechanically wrap the wiring onto the connection on the glass tube. I also found much debate on the advisability of soldering the connection on, with a consensus advising against it. Once a "connection" was made some form of fusion tape was usually used to complete the job.
In thinking about it I decided it would not be too difficult to make a mechanical connector that would be, perhaps, a bit more reliable than the aforementioned methods.
Attached are a couple of photos of a mechanical connector I made that will attach to both the copper connector from the tube and the Power Supply wire. On my particular tube the projection from the glass of the copper connector is just slightly longer than 1/8". I made the 2-56 tapped hole 1/16" from the end of a piece of 1/4" D. brass rod. The through hole is .056"D as the copper connecter is .055" D. I made the other 2-56 tapped hole .375" from the same end and the overall length of the brass rod is .5625". This leaves about 3/8" to insert the PS wire from the opposite end.
I think this will work pretty well. I even found some 1/4" fusion tape that is Red at McMaster-Carr
I just thought someone might have an interest in an alternate way to connect your wiring.
Comments are welcome
Regards,
Dick
