An electrical connector for providing an electrical connection between the body of a cordless electrical appliance and a base which in use is connected to an electrical supply has a male connector part (10), and a female connector part (12), the female connector part (12) comprising recesses (28, 26, 24) into which electrical contacts (30, 42, 52) extend, and the male connector part comprising electrical contacts (60, 62, 64) for engaging the contacts within the recesses of the female connector, allowing engagement of the male and female connector parts over 3600 of relative rotational orientation, wherein the female connector part (12) is provided with an isolating switch or switches connected to the electrical contacts having movable switch actuators (40, 50) extending into an annular recess (22) on the connector and disposed spaced from each other, and wherein the male connector part is provided with an annular surface arranged to protrude into said recess to engage the actuators and close said switches sequentially on mating of the male and female connector parts.
An electrical connector for providing an electrical connection between the body of a cordless electrical appliance and a base which in use is connected to an electrical supply, the connector comprising a male connector part for connection to one of the appliance or base, and a female connector part for connection to the other of the appliance or base, the female connector part comprising recesses or openings provided with electrical contacts, and the male connector part comprising electrical contacts for engaging the contacts within the recesses or openings of the female connector part, said recesses and contacts being adapted to allow engagement of the connector parts over 360° of relative rotational orientation, wherein one connector part for the base is provided with an isolating switch or switches connected to the electrical contacts having a movable switch actuator or actuators engageable by engagement means on the other connector part, wherein the actuators and said engagement means are disposed relative to the electrical contacts on said connector parts such that physical contact is made between said electrical contacts before closing of the switch or switches on mating of the connector parts, wherein the one connector part for the base is provided with an annular recess within which the switch actuator or actuators extend, and wherein the other connector part is provided with an annular surface arranged to protrude into said annular recess and close said switches on mating of the male and female connector parts.
An electrical connector for providing an electrical connection between the body of a cordless electrical appliance and a base which in use is connected to an electrical supply, the connector comprising a male connector part for connection to one of the appliance or base, and a female connector part for connection to the other of the appliance or base, the female connector part comprising recesses or openings provided with electrical contacts, and the male connector part comprising electrical contacts for engaging the contacts within the recesses or openings of the female connector part, said recesses and contacts being adapted to allow engagement of the connector parts over 360° of relative rotational orientation, wherein one connector part being for the base is provided with isolating switches connected respectively to live and neutral electrical contacts having movable switch actuators engageable by engagement means on the other connector part, said isolating switches being adapted to close sequentially one before the other on mating of the connector parts.
An electrical connector for providing an electrical connection between the body of a cordless electrical appliance and a base which in use is connected to an electrical supply, the connector comprising a male connector part for connection to one of the appliance or base, and a female connector part for connection to the other of the appliance or base, the female connector part comprising recesses or openings provided with electrical contacts, and the male connector part comprising electrical contacts for engaging the contacts within the recesses or openings of the female connector, said recesses and contacts being adapted to allow engagement of the male and female connector parts over 360° of relative rotational orientation, wherein one female connector part for the base is provided with an isolating switch or switches connected to the electrical contacts having movable switch actuators extending into an annular recess on that connector part, and wherein other connector part is provided with an annular surface arranged to protrude into said annular recess to engage the actuators and close said switches on mating of the male and female connector, wherein the switch actuator or actuators are provided at the lower end or ends with an upstanding skirt portion.
An electrical connector according claim to 23 wherein said annular recess has at least one opening therein for draining any fluid which is spilled in the recesses.
