It seems that Princess telephones — like the one I have — were notorious for having their connectors break. The connectors are made of brittle thermoset resin, and sit just where they’d hit the ground if you dropped the phone. This is definitely what happened here:
For the handset, you want a 616P connector. If your wall connector has gone too, you’ll need the 623P connector for that. These are fairly readily available on eBay.
These instructions really only apply to the 2702BMG model of the Princess phone. There are many variants, and the 2702BMG was one of the last Princess models made.
- Remove the upper body by unscrewing the two screws at each end of the base
- Remove the body, and remove the keypad. This is held in by two screws, one on each side of the keypad
- If your phone’s anything like mine, untwist the wires inside to get the line and handset connectors separated
- Unhook the old connectors from the terminals, and attach the new connectors as shown:
- Slot the handset modular connector into its space in the phone chassis
- Replace the keypad
- Re-route the wires so they don’t get pinched or block the handset hook, then re-attach the plastic body with the two screws.
