Headphones Audio Cable 3.2mm Pin Mmcx Pin Upgrade Plug

The universal pin of the MMCX plug of earphone wire is upgraded to a slot micro expansion. The plug is more compact and smooth. At the same time, the service life of beryllium copper ring pin is increased. At the same time, the problem of poor contact caused by long-term insertion and extraction is effectively avoided. In addition, it has a streamlined outer shell and a metal grinding shell.

The inner diameter of the outlet of the pin shell is about 3.2mm, so it is necessary to add a heat shrinkable tube at the end of the wire to improve its stability. The heat shrinkable tube can also effectively protect the end of the wire, killing two birds with one stone

Note: the solder joint of the pin base is small and difficult to operate. Some welding techniques are needed. The novice can paint flux and rosin on the wire rod and pin solder joint to make it easier to weld. The middle of the pin and the base is positive, and both sides are negative. Any one can be welded
