Rotatably locking plug and connector

A method for coupling an electrical connector to a cable, comprising:

• providing a housing configured to receive an electrical connector, the housing comprising:
• a spacer applying a first force in a first direction;
• a first channel disposed along an interior of the housing;
• a tab retention member disposed along the interior of the housing;
• and
• a second channel transverse the first channel and the tab retention member;
• providing an electrical connector comprising a tab;
• aligning the tab with the first channel;
• slidably moving the tab in the first channel in a second direction;
• applying a second force in the second direction on the electrical connector, the second force displacing the spacer in the second direction and providing access to the second channel;
• rotating the tab in a first direction along the second channel into alignment with the tab retention member;
• reducing the second force on the electrical connector;
• and
• displacing the tab in the first direction and into contact with the tab retention member.

A system for protecting an electrical coupling between an electrical connector and a conductor, the system comprising:

• a housing configured to protect the electrical coupling, the housing comprising:
• a spacer comprising a spring and configured to apply a force in a first direction against the electrical connector;
• and
• a locking ring configured to prevent the electrical connector from passing into the housing, comprising:
• a channel configured to allow the electrical connector to pass into the housing when the electrical connector is disposed in a first orientation with respect to the housing;
• and
• a retention member configured to hold the electrical connector within the housing when the electrical connector is disposed in a second orientation with respect to the housing.
