Sir C4reynol . . . . . . .
Should that be my problem to solve I would get one of the triple adapters shown at the left by virtue of its plastic
construction.
The ones to the right are no-no s due to HDPE construction medium or molecular nylon construction. They wont adhere to and FIRMLY bond with adhesives as compared to my reference unit.
The center connector just plugs onto yours and leaving a new connector on the outside.
Due to a skewed depth of field I cannot positively ascertain if your old unit is polarized . . . . .wide blade . . .narrow blade. Possibly appearing as wide blade on front left ?
So mate them accordingly.
The whitened area represents where you have original plastic missing, possibly with a thin sheet missing from the pink area.
You get two types of some hardware store epoxies as being shown at the left and the conventional more syrupy clear type shown at the right as two part tubes..
You knead the left side clay types until it blends into one color and it softens and warms up from both chemical action and your hands heat transference.
MOVE QUICKLY from that stage as it starts to harden QUICKLY and you have t get it over and molded/pressed into the cavities of the areas that were lost and press the adapter to it and conform to it.
Once you have it all contoured . . . . it then sets up rock hard for you.
Initially, to assure better inter bonding use a rasp or rough sandpaper to rough up the mating surfaces.
The final bonding would be around edges with the two part, which you might have to break up into 4 timed stages due to positioning in order to avoid running off, of of the somewhat syrupy mix from the seams between the two surfaces..Or use masking tape strips to build up dams to restrict any run off.
Thassssit . . . . .
