Abstract
A male connector and mating female connector for use in a cordless electric water beating jug. The male connector has a cup-shaped body with an open base within which are located a central pin terminal and two concentric annular terminals. The body of the female connector is dimensioned to fit within the male connector and has openings to receive the pin terminal and the inner annular terminal so that they may engage two female terminals. A further female terminal projects from the side wall of the female connector for engagement with the outer annular male terminal.
Claims19
An electrical power connector for a cordless electrical appliance, said connector comprising a male connector part and a female socket connector part for engagement therewith, said male connector part comprising:
- a central conducting pin terminal;
- an annular terminal concentric with the pin terminal;
- and
- an inwardly facing circumferential surface arranged radially outwardly of said annular terminal and providing an earth terminal;
- said female socket connector part comprising:
- a body with openings formed in a forward end thereof for receiving the central pin terminal and the annular terminal of the male connector part and having an outer circumferential surface for engagement within the inwardly facing circumferential surface of the male connector part;
- and
- respective electrical contacts for engaging with the central pin terminal and the annular terminal of said male connector part when the terminals are received in the openings of the female connector part, wherein the outer circumferential surface has an exposed earth contact for engagement with the earth terminal of the male connector part.
An electrical power connector for a cordless electrical appliance comprising a male connector part and a female socket connector part for engagement therewith in any relative rotational orientation, said male connector part comprising:
- a central conducting pin terminal;
- an annular terminal concentric with the pin terminal;
- and
- an inwardly facing circumferential surface arranged radially outwardly of said annular terminal and having an annular earth terminal;
- said female socket connector part comprising:
- a plastics body with unshuttered openings formed in a forward end thereof for receiving the central pin terminal and the annular terminal of the male connector part and having a side wall defining an outer circumferential surface for engagement within the inwardly facing circumferential surface of the male connector part;
- and
- respective electrical contacts for engaging with the central pin terminal and the annular terminal of said male connector part when the terminals are received in the openings of the female connector part, wherein an earth contact for engagement with the earth terminal of the male connector part extends through the side wall of the female connector part which defines the outer circumferential surface for engagement with the annular earth terminal of the male connector part.
An electrical power connector for a cordless electrical appliance comprising a male connector part and a female socket connector part for engagement therewith, said male connector part comprising a central conducting terminal and an annular terminal concentric therewith, said female socket connector part forming openings in a forward end thereof for receiving said terminals and having respective electrical contacts for engaging with said terminals, wherein the opening for receiving the annular terminal is in the form of an annular channel and the contact associated therewith is resiliently mounted such that the contact extends through a bottom of the annular channel and is biased towards a forward end of the female connector part.
In combination, a cordless electrical appliance and a power supply base unit therefor, comprising an electrical power connector for supplying electrical energy from the base unit to the appliance, said connector comprising a male connector part and a female socket connector part for engagement therewith, said male connector part comprising:
- a central conducting pin terminal;
- an annular terminal concentric with the pin terminal;
- and
- an inwardly facing circumferential surface arranged radially outwardly of said annular terminal and providing an earth terminal;
- said female socket connector part comprising:
- a body with unshuttered openings in a forward end thereof for receiving the central pin terminal and the annular terminal of the male connector part and having an outer circumferential surface for engagement within the inwardly facing circumferential surface of the male connector part;
- and
- respective electrical contacts for engaging with the central pin terminal and the annular terminal of said male connector part when the terminals are received in the openings of the female connector part, wherein the outer circumferential surface has an exposed earth contact for engagement with the earth terminal of the male connector part.
In combination, a cordless electrical appliance and a power supply base unit therefor, comprising an electrical power connector for supplying electrical energy from the base unit to the appliance, said connector comprising a male connector part and a female socket connector part for engagement therewith in any relative rotational orientation, said male connector part comprising:
- a central conducting pin terminal;
- an annular terminal concentric with the pin terminal;
- and
- an inwardly facing circumferential surface arranged radially outwardly of said annular terminal and providing an annular earth terminal;
- said female socket connector part comprising:
- a plastics body forming openings in a forward end thereof for receiving the central pin terminal and the annular terminal of the male connector and having a side wall defining an outer circumferential surface for engagement within the inwardly facing circumferential surface of the male connector part;
- and
- respective electrical contacts for engaging with the central pin terminal and the annular terminal of said male connector part when the terminals are received in the openings of the female connector part, wherein an earth contact for engagement with the earth terminal of the male connector part extends through the side wall of the female socket connector part for engagement with the annular earth terminal of the male connector part.
