I use a surgical headlight for work. I know next to nothing about small electronics. It is a small LED light which mounts onto my glasses and has an integrated/fixed cable running from the back of the small LED down along my glasses arm then to a small cable to a 3.5mm connector near waist level. The LED light is supposed to be 3 watts. It is powered by an external battery which has a jack input in 3.5mm obviously.
The battery lists the INPUT from the charger as 8.4 volts then it has a long solid line over three dashes and lists 11.5A. It then lists the output at 7.4V 2600 mAh. There are 3 gold band zones on the pin connectors interrupted by 2 black bands.
The problem I am running into, over and over again, is there isn’t any built in stress relief design in the cable. As you move the cable gets twisted and torqued where the wire enters the plug into the battery. So at the 3.5mm connector near the battery I keep getting shorts. I have cut/resoldered and shrink wrapped the cable several times, but it always reoccurs.
My question is: Maybe I can use a coiled type connector as the connection to the battery and then plug the light cable into that. Maybe even just a sacrificial length? I envision a female to male cable type and I would plug the light from the cable into that one. This should eliminate the stress on the cable/battery connection. I am just unsure what and where to buy such a cable. I assume this is a different type of 3.5mm cable/connection to carry 7.4V compared to an audio/headphone cable.
Can anyone shed some light on this for me and help me figure out what/where to buy? Please?
