Definitions

  • the present invention is related to an electrical connector, especially related to a rotatable connector for use with a cordless and detachable electrical appliance, such as electrical heater pot, cordless frying pan, cordless electrical flatiron and so on.
  • a cordless and detachable electrical appliance such as electrical heater pot, cordless frying pan, cordless electrical flatiron and so on.
  • CN1135270A corresponding document WO 9508204 A1 ("Cordless electrical appliances and connectors therefore"), disclosing the preambles of claims 1 and 10, provides a rotatable electrical connector, including an electronegative tie-in(plug)and an electropositive tie-in (socket).
  • the plug includes a center conducting pillar receiving terminal lug and a ring receiving terminal lug being concentric with that terminal lug.
  • In the front of the socket there is an opening for accepting the center pillar receiving terminal lugs and the ring receiving terminal lugs of the plug.
  • the socket has a separate power supply contact for bonding with the receiving terminal lugs.
  • This design makes the plug in the bottom center of electrical appliance near its barycenter or at the same plumb line with it, and freely rotates relative to power supply pedestal without impeding the electrical connecting effect from the horizontal direction, which makes the electrical appliance setting in the power supply pedestal more firm and gets better connecting effect.
  • the socket is being power supplied continuously, that is, the contact sheet in the center hole or ring grooves is being electrified continuously. So, for avoiding getting an electric shock accident and assuring the connecting effect, the diameter of the center hole and ring groove's width must be very small, normally, no more than 3mm, which requires the user to align the plug and socket straight carefully when using. Therefore, it makes the user's inconvenience; on the other hand, because it limits the size of supply pedestal, when the power supply to the electrical appliance is large and a larger size of connector is needed, it's hard to realize.
  • This invention addresses the limitations in the prior art described above. It provides a new connector for cordless electrical appliance, which keeps the connecting contact sheet of socket connected with plug being power off all the time while the plug is not inserted.
  • EP 1 253 679 which was published after the priority date of the present application but which has an earlier filing date describes an electrical connector for use with, for example, a cordless kettle. It describes a switching mechanism whereby electrical power to terminals in the power supply base of the kettle is inhibited whilst no kettle stands on the base. In this state contacts to supply power to such terminals are held apart. When a kettle is placed on the base this operates actuators allowing the spaced contacts to move into contact with one another such that power can be supplied to the terminals.
  • the actuators are in the form of pins which are separate from the electrical contacts between the base and the kettle.
  • an electrical connector as claimed in claim 1.
  • the present device sets up two pair of mutually corresponding power supply contact sheet teams, and when the plug isn't inserted into the socket, in the power supply contact sheet team at least one of them connected with the live wire or zero line of power supply and its corresponding power supply contact sheet keeps normally open, which makes that the visible power supply contact sheet of the socket surface is not electrified all the time, and also not only safety in use, but also facilitative connection on account of the unrestricted width and depth, even inserting incliningly, the effect is the same.
  • the present arrangement will make it possible to design, manufacture and utilize larger power electrical connector, and widen its applied field dramatically, support the variegated development of products such as electrical pot and electrical frying pan.
  • Example one as shown in Figs 1 , 2 , includes a plug 100 and a socket 200 that are interconnectable and relatively rotatable.
  • a plughole In the center of the socket's upper face there is a plughole and a number of ring grooves being concentric with the plughole, inside the plughole is a center power supply receiving pillar 202, inside and outside the ring groove there are power supply contact sheets 201, 203, inside the power supply contact's 201 underside there is an immovable contact 201a extended outwards, and outside the power supply contact 203 there is an immovable contact 203a.

  • the power supply contacts 301, 303 are respectively connected with the live wire and the zero line of the power supply, and on the one side of the supply contact sheet 301 there is a movable contact 301a, opposite to a immovable contact 201a of the power supply contact 201; on the one side of power supply contact sheet 303 there is a movable contact 303a, opposite to an immovable contact 203a of the power supply contact sheet 203.

  • the isolating pushrod 304 under the action of its two sides acts on two power supply contact sheets 301, 303 at the same ti me, however, in practical application, it can act one of the power supply contact sheets only through one side, and another power supply contact is connected directly with its corresponding line of power supply.
