Patent attributes
A twist-lock electrical connector includes first and second connector portions each having a respective interface end portion and longitudinal axes. The first connector has a projection and the second connector has a corresponding bore along the connectors' respective longitudinal axes. Two electrical contacts are located at opposite sides of the projection at the first interface end portion, and two other electrical contacts are located at opposite sides of the bore at the second interface end portion. The interface end portions are configured to engage one another at a first rotational orientation in which the bore receives the projection when the first and second longitudinal axes are made substantially coaxial and the connector portions are brought together along their axes. The interface end portions further engage one another at a second rotational orientation in which the first pair of electrical contacts electrically engage the second pair of electrical contacts.
