Claims
- 1. An electric hotplate, comprising:
- a hotplate member;
- electrical heating resistor means for heating at least a zone of said hotplate member;
- a covering sheet covering at least the underside of the heated zone of said hotplate, including said heating resistor means, the sheet having an opening therethrough;
- a plurality of flexible, thermally and electrically insulated electrical connection means, each being electrically connected at one end to said heating resistor means and extending through said opening for connecting said heating resistor means to a source of electrical energy;
- a connecting member for mechanically connecting said flexible electrical connection means to one another near their other ends, said connecting member being freely movable relative to said hotplate member in all directions, limited only by the length of said electrical connection means;
- said covering sheet having an upwardly projecting depression angularly displaced from said opening and sufficiently large to accommodate said connecting member during transport; and,
- said flexible electrical connection means being of sufficient length to enable the connecting member to be operationally mounted outside the region of the hotplate after transport.
- 2. An electric hotplate according to claim 1, further comprising an insulating member inserted into said opening and having passages therethrough for said electric connection means, said insulating member projecting downwardly beyond the covering sheet.
- 3. An electric hotplate according to claim 2, wherein the the depression and the insulating member are equally radially spaced from the center of the covering sheet but angularly displaced from one another.
- 4. An electric hotplate according to claim 3, wherein the depression is sufficiently larger than the insulating member to accomodate a connecting member as well.
- 5. An electric hotplate, comprising:
- a hotplate member;
- electrical heating resistor means for heating at least a zone of said hotplate member;
- a covering sheet covering at least the underside of the heated zone of said hotplate, including said heating resistor means, the covering sheet having an opening therethrough;
- a plurality of flexible, thermally and electrically insulated electrical connection means, each being electrically connected at one end to said heating resistor means and extending through said opening for connecting said heating resistor means to a source of electrical energy; and,
- a connecting member for mechanically connecting said flexible electrical connection means to one another near their other ends, including clamping means for mechanically clamping the flexible electrical connection means near their free ends and holding them parallel to one another, said clamped free ends forming connector plug means, said connecting member and said connector plug means formed thereby being freely movable relative to said hotplate member in all directions, limited only by the length of said electrical connection means, said flexible electrical connection means being of sufficient length to enable the connecting member to be operationally mounted outside the region of the hotplate.
- 6. An electric hotplate according to claim 5, wherein the connecting member includes connecting clips for connecting the flexible connection means to the source of electrical energy.
- 7. An electric hotplate according to claim 5, wherein the connecting member holds the flexible connection means in side-by-side relationship.
- 8. An electric hotplate according to claim 5, wherein the hotplate member is substantially circular and the length of the flexible connection means is such that the operational mounting of the connecting member can be at any distance from the border of the hotplate member which is less than the radius of the hotplate member.
- 9. An electric hotplate according to claim 5, wherein the flexible electrical connection means comprises several separate wires welded to connecting pins of the hotplate.
- 10. An electric hotplate according to claim 5, wherein the connector plug means are oriented so as to be insertable into a socket means and being so shaped as to be insertable into the socket means in only one direction.
- 11. An electric hotplate according to claim 5, wherein the connecting member comprises channels, the ends of the flexible connection means inserted therein being secured in the channels and fastened by deformation of said ends.
- 12. An electric hotplate according to claim 11, wherein the channels in the connecting member are apertures having an internal shoulder for engagement of a corresponding shoulder provided near the ends of the flexible electric connection means.
- 13. An electric hotplate according to claim 11, wherein the flexible connection means comprise stranded wires having ends surrounded by multicore cable end-splices.
- 14. An electric hotplate according to claim 13, wherein the end-splices are formed into their final shape after being inserted into said channels.
- 15. An electric hotplate according to claim 14, wherein the connecting member comprises recesses into which parts of said end-splices are inserted during formation of the end-splices.
- 16. An electric hotplate according to claim 5, wherein said connector plug means cooperate with socket means, which comprise spring clip means for gripping and holding the connector plug means as well as leads leading to the source of electrical energy, wherein said spring clip means are self-locking for said leads and not self-locking for said connector plug means.
- 17. An electric hotplate according to claim 5, further comprising an insulating member inserted into said opening and having passages therethrough for said electrical connection means.
- 18. An electric hotplate according to claim 17, wherein the insulating member is disposed radially closer to the border of the hotplate member than to the center thereof. PG,36
- 19. An electric hotplate according to claim 17, wherein the heated zone is of annular shape and the insulating member is substantially centered between the inner and outer radial edges of the heated annular zone.
