Description
Technical field
The present invention relates to the cordless electric connecting devices for electric appliance.
Background technology
Cordless (cordless) electric appliance generally includes electric appliance itself and power base, and each equipment has corresponding nothing
Cord connector is supplied power to when cordless connector to be placed in power base by the cordless connector
Electric appliance itself.Power base is connected to main power source by power cord.Cordless connector can be such as WO-A-1994/06185
Disclosed in 360 ° of cordless connectors, allow electric appliance itself with fixed around substantially any rotational angle of the axis of connector
Position is on base portion and is connected to base portion.Alternatively, cordless connector may permission electric appliance itself oriented at one or limited
The determining of range is connected upwardly to power base.
Cordless connector typically comprises the cordless plug connector being generally arranged on the bottom surface of electric appliance itself
With the corresponding cordless socket connector being generally arranged on the upper surface of power base.A pair for linking together is right
The cordless connector answered can be referred to as cordless connector system or equipment.
The weight of electric appliance itself should be greater than or equal to electric appliance itself to be docked to insertion force required in power base, otherwise
User will need to push down on electric appliance itself in power base.The weight of power base should be greater than or be equal to electric appliance itself
Required withdrawal force is removed from power base, otherwise when user attempts to lift electric appliance itself from power base, power supply
Base portion may be together suggested with electric appliance itself.
Insertion force and/or withdrawal force can pass through the contact and cordless socket connector in cordless plug connector
In corresponding contact between contact force determine, and if using slide contact member, pass through rubbing between contact
Power is wiped to determine.
When connector is fully coupled together, connector (or they install the power base and electric appliance sheet at place
Body) meeting of shape and construction prevents them from being continued to move to along connection directions;In this case, connector can be referred to as
Full connection or completely docking.For example, when electric appliance itself is placed in power base, it may occur that such case.
Usually using two kinds of electric contact piece in cordless connector:End contact and slide contact member.Fig. 1 and
Fig. 2 respectively illustrates the example of each contact, and it illustrates the contact sites of the CS8 sockets and CP1 pin connectors of applicant
Point.
Pin connector is connected to socket connector along connection direction D, connects shapes of the direction D by socket and pin connector
Shape and construction determine.In practice, one of connector (such as in power base) is fixed, and another connector
(such as in electric appliance itself) is moved along connection direction D to be connect with fixed connector.However, situation is not necessarily so, therefore
Connection direction D should be understood the relative direction between pin connector and socket connector.
As shown in Figure 1, center band electrical connection, using end contact arrangement, the contact of spring contacts 1 wherein in socket is inserted
The end of pin 2 in head.Spring contacts 1 apply upward power to pin 2, this has contributed much entire insertion force, insertion force
It must be overcome by the weight of electric appliance itself.
In identical connector system, neutral contact and grounding component are slidingtypes, as shown in Figure 2.When slotting
When head connector and socket connector link together, spring connector 3 slides on the cylindrical surface 4 of pin connector.
In sliding contact arrangement, the insertion force on connection direction D is tended to less than the insertion force in end contact arrangement, but pulls out
It contributes higher (on the direction opposite with connection direction D).In fact, for end contact arrangement, since spring connects
Contact element 1 will be tended to pin connector pushing away socket connector and electric appliance itself is therefore deviateed power base, so having
Negative sense withdrawal force.
The cordless connector of the above-mentioned type heats/boils electric appliance commonly used in liquid, such as kettle or milk foam occur
Device.If electric appliance is for heating or boiling liquid than water, it would be desirable that connected using waterproof cordless in electric appliance itself
Device, so as to clean electric appliance itself for example in dish-washing machine.This waterproof cordless is disclosed in WO-A-2008/012506
The example of connector.
The cordless connector of the above-mentioned type usually has for charging, neutral and grounding connection at least three electrodes.
More complicated electric appliance may need additional electrode, such as sending signal between power base and electric appliance itself.Especially
It is it is desirable that not including in electric appliance itself by electronic unit, such as the case where electric appliance itself should can wash
Under, so that the situation sensed in electric appliance itself needs the controller being signaled in power base.Increase cordless to connect
Insertion force and/or withdrawal force would generally be increased by connecing the quantity of electrode or contact in device.
Smaller electric appliance needs cordless connector;In an example of smaller electric appliance, electric appliance itself can be with weight
No more than 350g and power base is no more than 200g.However, 6 electrode cordless connection system usually with 6N insertion force and
The up to withdrawal force of 3N.Especially in the case where there is a large amount of electrode, it is difficult to realize using the mixing of two types contact
Low insertion force and low withdrawal force.
Thus, for example need reduce cordless connection system insertion force and withdrawal force, so as to it can be used for it is smaller
Electric appliance.This demand particularly but not exclusively may be applied to the cordless connection system more than 3 electrodes.
Cordless connection system another problem be likely to occur in when being attached or disconnecting electrification or in
Arc discharge at property contact.In order to meet safety standard, live contact and neutral contact should be after grounding components
It is formed into a loop and is disconnected before grounding component.Best only one of which neutral contact or live contact should shapes
At or disconnect circuit, rather than allow electrification or neutral contact may execute these functions.For example, live contact may
It is formed into a loop, and can be disconnected back before grounding component or neutral contact after grounding component and neutral contact
Road.
The fragment generated by arc discharge can lead to higher contact resistance, and therefore lead to the fortune of cordless connection system
Trip temperature is excessively high, this may damage the reliability of electric appliance and safety.

Specific implementation mode
Specific embodiments of the present invention include cordless connection system, which includes first at least three electrodes
Cordless connector and the second cordless connector or separated electrical connection.Each electrode is included in the first cordless connector
With the corresponding electric contact piece in the second cordless connector, electric contact piece is arranged to when the first cordless connector and second
Electrical connection is formed when cordless connector links together.
The specific arrangement of electric contact piece is described with reference to the schematic diagram of figure 3 to 14.For the sake of clarity, some show more
The contact of a electrode in the same plane, but the contact of actually distinct electrode can be arranged in different planes.
Fig. 3 shows the electric contact piece in one embodiment of the present of invention comprising:
-- neutral pin 10 and corresponding neutral sliding spring contact 40;
-- electrification or signal pin 20 and corresponding electrification or signal sliding spring contact 50;With
-- ground pin 30 and corresponding ground connection sliding spring contact 60.
For connector only there are three in the case of electrode, these may be neutral, electrification and ground connection.Unless it is necessary to carry
It is connected for more than one independent power, otherwise additional electrode may be signal electrode, may provide in this case
Additional charged electrode and neutral electrode.
Each neutral, electrification and ground pin 10,20,30 usually extend on connection direction D, which is in Fig. 3
Vertical direction, but have inclined contact surface 11,21,31, the contact surface 11,21,31 relative to connection direction D incline
Tiltedly.Each neutral, electrification/signal and ground spring contact 40,50,60 have a corresponding contact portion 41, and 51,61, at least
When cordless connector connects or disconnects, which contacts corresponding inclined contact surface
11,21,31.Neutral contact part 41 and electrical contacts part 51 may include being attached to 40 He of corresponding neutral spring contacts
Charge the low resistivity contact material of spring contacts 50.It is grounded contact portion 61 and signal contact portion 51 can be by corresponding
Ground spring contact 60 and signal spring contacts 50 be formed by bending.
Inclined contact surface 11,21,31 is tilted towards corresponding contact portion 41,51,61 so that contact portion 41,
51,61 contact inclined contact surface 11,21,31 during the first and second cordless connectors connect and are connect along inclined
Surface 11,21,31 is touched to slide.Inclined contact surface 11,21,31 is along the pin with 40,50,60 sliding contact of spring contacts
Sizable ratio (for example, being more than 50%) of 10,20,30 length extends:In the case where charging pin 20, this ratio is
100%.Inclined contact surface 11,21,31 preferably exists only on an edge of pin 10,20,30.
Due to requiring the last progress of band electrical connection and disconnecting first, neutral contact part 41 and ground connection contact portion 61
It can move on connection direction D along corresponding neutral pin 10 and ground pin 30 and be moved along electrification pin 20 than electrical contacts part 51
The distance of dynamic bigger, wherein ground connection contact portion 61 is farthest mobile.It is also desirable that neutral pin 10, electrification pin 20 and ground pin 30 have
There is identical width (for example, horizontal direction on) in figure 3.Therefore, when connector fully connects, neutral contact part
41 can slide past corresponding inclined contact surface 11,31 with ground connection contact portion 61 is arranged essentially parallel to connection to pin 10,30
In the vertical contact surface 12,32 that direction D extends.Because insertion force reduces, this can provide a user feedback, i.e., connector is complete
Full docking.When connector is fully connected, electrification/holding of signal contact portion 51 is contacted with the inclined of electrification/signal pin 20
Surface 21 contacts.
As shown in Fig. 4,5a, 5b, 6a and 6b, 10,20,30 relatively flat of pin:Such as their width is significantly greater than them
Thickness, and they can be made of stripping.The thin edges of pin 10,20,30 contact corresponding spring contacts, to
Reduce the friction between them.
The close end of pin 10,20,30 may include terminal part 15,25,35.Spring contacts 40,50,60 can with
In in socket connector corresponding installation section 47,57,67 and the connection of corresponding terminal part 45,55,65 or
It is integrally formed.
As shown in fig. 7, neutral contact part 41 and ground connection contact portion 61 are against corresponding neutral pin 10 and ground pin 30
Reactive spring force F1Substantially horizontal (i.e. perpendicular to connection direction D), therefore have no substantial effect on insertion force and pull out
It contributes;The contribution of neutral electrode and grounding electrode is almost frictional property.On the contrary, as shown in figure 8, electrification/signal contact
Reactive spring force F of the part 51 against the inclined contact surface 21 of electrification/signal pin 202It tilts upwards from horizontal direction,
Make capable F2Component acted on on the opposite vertical directions of connection direction D, so that cordless connector bias is separated.It should
Bias reduces withdrawal force, and the frictional force during helping compensate for extracting on neutral pin 10 and ground pin 30.The vertical force
Size can be determined by the angle of inclined contact surface 21.In electrification/signal contact portion 51 and angled contact
Being still had between surface 21 contributes to some of insertion force and withdrawal force frictional force, but the component of friction of withdrawal force is by power F2
Vertical component reduce.
In the embodiment for connecting system including 6 electrodes, there are charged electrode, neutral electrode and grounding electrode and three
Signal electrode.When connector docks completely, as shown in figure 8, the contact portion 51 of charged electrode and signal electrode is kept and phase
The inclined surface 21 answered contacts, and neutral contact part 41 and ground connection contact portion 61 and corresponding pin 10, and 30 connect vertically
Surface contact is touched, as shown in Figure 7.Accordingly, there exist four inclined surface contacts and two vertical surface contacts.If
Lower insertion force is needed, then might have less inclined surface contact electrodes and more vertical surfaces contact electrode.
Alternatively, one or more inclined surfaces 21 can be tilted more towards vertical direction.Therefore, insertion force and withdrawal force can be according to electricity
The specific requirement of device is adjusted.
Electrification pin 20 and spring contacts 50 and its contact portion 51 can be designed to reduce arc discharge to contact resistance
Influence.Preferably, this is realized by being arranged in such a way, that is, allows to initial/most terminating that arc discharge occurs
Tactile region does not form a part for the operation contact area in docking arrangement completely.
Fig. 9 is shown if there are high potentials (for example, power supply potential between electrification pin 20 and electrification spring contacts 50
For 110V or 240V RMS) in the case of, it may occur however that when arc discharge, before the initial contact of connection or disconnect
It is final contact after, at the point at minimal-contact interval electrification pin 20 and charge spring contacts 50 position.It is charging
At the tip of pin 20 and the top of contact portion 51 and/or electrification spring contacts 50 the part higher than contact portion 51,
Such as at bending section 53, between be likely to occur potential arc discharge positions A.It is found at these arc discharge positions A big
The deposition of part galvanic corrosion and arc discharge clast.
Figure 10 is shown when connector docks completely, is charged pin 20 and is charged the position of spring contacts 50.Operation electricity
Contact C is located between the top and the center of contact portion 51 of the inclined surface 21 of electrification pin 20.Therefore, electric contact piece is operated
The contact resistance of C keeps relatively low and only results in the acceptable temperature rise for arriving stable state in operation.
The angle on inclined surface 21 and/or the profile of contact portion 51 can be designed to reduce arc discharge to contact
The influence of resistance.For example, contact portion 51 can be with raised contact surface so that operation electric contact piece C and contact portion
Potential arc discharge positions A separation on 51.
As shown in figure 11, with electrification pin 10 and neutral pin 20 can be brass material compared with, at least in electrification pin 10
On neutral pin 20, inclined surface 11,21 may include the contact surface 15 of low resistivity material (such as silver or silver alloy),
25.Because contact portion 41,51 is rolled around contact surface 15,25, so the length of contact surface 15,25 can reduce:It connects
Sliding contact point in contact portion point 51 is moved to the central part of contact portion 51 from the distal end of contact portion 51, therefore sliding connects
Some distances of contact element are occupied by contact portion 51 rather than contact surface 25, therefore reduce the cost of low resistivity material.
Low resistivity material can by pin 10,20 formed slot and by correspondingly configured be partially fitted in slot of low resistivity material and
It is attached to pin 10,20;Slot and low resistivity material may, for example, be wedge shape.
