This is not a solution that would help the wheelchair user, but if you have a set of inexpensive ($10 bought in the US, less from china) 3" digital calipers, you could likely measure the socket and get it 3D printed. I've done it for obsolete electrical connectors in cars and while it takes time and some effort, it's very doable.
- sokoloff 2y agoThese are high-current (30-50A range) connectors though (for the wheelchair traction batteries). Getting the positioning correct so that the spring tension in the metal terminals creates a reliable/low-resistance/non-sparking connection is a shared contribution from the geometry of the metal terminal and the plastic housing (as opposed to most low current (0-5 Amp) electrical connections, where the connection geometry is most commonly provided by the metal geometry alone and the plastic's contribution is just keeping them "organized and close enough to mate").
