Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
With reference to accompanying drawing: the power connector in the present embodiment is mounted on the electric cooker.Pot 1, outer pot 2, pot body 11 in electric cooker comprises, outer pot 2 places in pot body 111, and interior pot 1 can be positioned in the outer pot 2, also can independently take out.Power connector comprise the seat of honour 3, following 6, the seat of honour 3 be fixed in pot 1 bottom, following 6 is connected with outer pot 2.The seat of honour 3 is provided with electric heating part 12, and the bottom of electric heating part 12 is provided with one group of fixedly electric connection 4.Electric heating part 12 is Electric radiant Heating Film, and fixedly electric connection 4 is printed in the Electric radiant Heating Film surface by mode of printing.Following seat 6 be provided with one group with fixing electric connection 4 corresponding flexible lamp joints 8, flexible lamp joint 8 is movable parts, flexible lamp joint 8 is provided with boss 8-1, is supported with electrode spring 9 between boss 8-1 and following 6.Following seat 6 is located on the guide rail 5, and is with guide rail 5 and is slidingly matched, and following 6 supported underneath has a following spring 7.Flexible lamp joint 8 is positioned at following 6 installing hole 6-1.The side of installing hole 6-1 is provided with the seal 10 that can move horizontally, and the top of sealing part 10 is provided with the catch 10-3 that is used to seal installing hole 6-1; Also have pilot hole 10-2 on the catch 10-3, the bottom at the seat of honour 3 is provided with the guiding surface 3-1 that is complementary with this pilot hole 10-2; Back-moving spring 10-1 also is housed on the seal 10.Earth connection point in the flexible lamp joint 8 is higher than live wire joint and zero line joint.As shown in Figure 1 and Figure 2, middle that root flexible lamp joint 8 is earth connection point.
Following seat 6 is movable an of elasticity, and it is connected with a guide rail 5 and a following spring 7, and following seat 6 can move up and down along guide rail 5, and following seat spring 7 makes down under the seat 6 no pressured states and can automatically reply original position.Flexible lamp joint 8 among the installing hole 6-1 of following seat 6 comprises live wire joint, earth connection point down, following zero line joint down.Each flexible lamp joint 8 is movable, is socketed with electrode spring 9 on it.Electrode spring 9 is supported between boss 8-1 and the installing hole 6-1 diapire.Electrode spring 9 moves down after making each flexible lamp joint 8 pressurized, can automatically reply original position under the no pressured state.Electrode spring 9 makes flexible lamp joint 8 have the self-adjusting function.The fixedly electric connection 4 of electric heating part 12 bottoms comprises the wire terminal of getting angry, goes up earth connection point, goes up the zero line joint.
As shown in Figure 1, do not put into outer pot 2 fully when interior pot 1, each flexible lamp joint 8 is hidden in down among the installing hole 6-1 of seat 6.The seal catch 10-3 on following seat 6 surfaces is closure state, covers each flexible lamp joint 8, guarantees that live wire joint, earth connection point down, following zero line joint can not expose down.
As shown in Figure 2, after interior pot 1 was put into outer pot 2 fully, following seat 6 pressurizeds moved down along guide rail 5, and seal 10 is opened, following live wire joint in the following seat 6, earth connection point down, the zero line joint exposes down, with the wire terminal of getting angry on the 3 bottom electrical hotting masks of the seat of honour, go up earth connection point, go up the zero line joint and contact.Because down earth connection point is a little more than live wire joint and zero line joint down down, guarantee to contact at first putting into 1 o'clock ground wire of pot, pot 1 o'clock ground wire disconnects at the latest in taking away, and guarantees security appliance.Because down live wire joint, earth connection point down, the zero line joint is movable of elasticity down, each joint is self-movement, can guarantee with Electric radiant Heating Film on the wire terminal of getting angry, go up earth connection point, go up the zero line joint and well contact.
After interior pot 1 was taken away, following seat 6 reverted to Fig. 1 state, guarantees security appliance.
As shown in Figure 3,3 surfaces, the seat of honour are provided with guiding surface 3-1, and seal 10 is provided with pilot hole 10-2 and back-moving spring 10-1.When interior pot 1 was not put into fully, seal 10 was subjected to back-moving spring 10-1 effect, with following 6 be closure state, its catch 10-3 covers installing hole 6-1, each flexible lamp joint 8 does not expose.As shown in Figure 4, when interior pot 1 was put into fully, the seat of honour 3 was pressed in down on the seat 6.Guiding surface 3-1 on the seat of honour 3 inserts among the pilot hole 10-2 of seal 10, be subjected to guiding surface 3-1 and back-moving spring 10-1 effect, seal 10 is along moving horizontally certain displacement, and each flexible lamp joint 8 exposed and contact the realization electrode conduction with fixedly electric connection 4 on the seat of honour 3 this moment.After interior pot 1 was taken away, seal 10 was subjected to back-moving spring 10-1 effect, reverts to closure state, guarantees that the user can not directly contact flexible lamp joint 8, guaranteed that the user is safe in utilization.
Following seat is certainly as movable part, when interior pot is not put into, the flexible lamp joint of following seat is concealed and by the seal sealing, can't contact electrode when guaranteeing charged cleanings of user, and the assurance user security, after interior pot is put into, move down behind the following seat pressurized, seal is opened, and the flexible lamp joint exposes, owing to earth connection point is longer down, at first contact earth connection point on the seat of honour.Following each flexible lamp joint of seat relies on spring or from realizing independently movable as elastic component and having self-adjusting, guarantees that each joint contact of each contact of lower contact and the seat of honour contacts well, and only need silver-plated the getting final product of power-on and power-off joint head that cost is lower.
Though the utility model illustrates and describes by the reference preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
