This bracket makes it possible to directly mount the solderable DC connector socket to the wall of the project enclosure. I cut the side pin as it is not used, then bend backwards the middle pin carefully to be able to slide on the bracket from the back onto the connector socket. Then make a square 10x9 mm hole to protrude the DC connector fron throught the wall of the project enclosure and two 3mm holes for mounting the bracket. Use M3 screws to moung the bracket by directly screwing into the bracket mounting holes.
Use M2 screws from top and if needed bottom to tighten the bracket around the DC connector socket
