Mystery 2 pin connector to identify
These were amongst a job lot of bits and pieces that I recently acquired.
Does anyone know what they are called and their main application(s)? |

Possibly home made, for connection to dry batteries that had a socket outlet, AD 28, HP 1, and various HT batteries.

Re: Mystery 2 pin connector to identify
The Paxolin circle is reminiscent of a fluorescent light starter contact plate- perhaps, as broadgage says, it was adapted for battery contact use.

Re: Mystery 2 pin connector to identify
Another possibility is the type of plug used for headphones in the crystal set era.
I assume that the two holes in the paxolin are a crude form of cable grip. Alternatively a loop of cord could be attached to help to unplug it. |

Re: Mystery 2 pin connector to identify
How big is it?
Its not dissimilar to the power connector so beloved by Bush on DAC90s and similar sets if its that sort of size Cheers Mike T

Re: Mystery 2 pin connector to identify
The two holes at 90-degrees to the pins suggest they could have been for the connecting flex to feed through as a kind of strain-relief for the flex-to-pin connections.
I'd think it was a battery-connector, or maybe used to connect an extension-speaker to a radio.

Re: Mystery 2 pin connector to identify
I should have added a ruler in my previous photos to give some idea of size. Here’s one now.
My digital micrometer says the pins are 1.97 mm diameter. I doubt it was for HT or LT battery connections, as the two pins are the same diameter, so not polarised. Still intrigued as to its use(s). |

Re: Mystery 2 pin connector to identify
Possibly a battery connector despite not being polarised.
Incorrect polarity of the heater supply seldom matters, and HT could be determined by trial end error without harm, as when connecting a valve set to DC mains. |

Re: Mystery 2 pin connector to identify
Antenna/earth connector or speaker connector as already mentioned?
