Abstract
An explosion proof connector is provided with first and second electrical connectors and first and second threaded sidewalls that surround the electrical connectors. The threaded sidewalls engage to secure the electrical connectors in electrical connection. Either the first threaded sidewall is rotatable relative to the first electrical connector or the second threaded sidewall is rotatable relative to the second electrical connector. A ratchet lock is carried by the first sidewall, and a ratchet surface is carried by the second sidewall, the ratchet lock being releasable and biased toward engagement with the ratchet surface. The ratchet lock permits rotation of the second sidewall relative to the first sidewall in a first direction and prevents rotation of the second sidewall relative to the first sidewall in a second direction. A release mechanism disengages the ratchet lock and permits the second sidewall to rotate in the second direction relative to the first sidewall.
