In this embodiment according to switching device of the present invention, for example there is and comprises at least one magnetic core 11 in switching units AE as the switching units of electromagnetism, and described magnetic core inserts movably with respect to coil 12 at least one coil 12 (magnet exciting coil) and by unshowned director element along its longitudinal direction and guides.Supply with coil 12 electric energy and especially electric current by corresponding electric wire 13, described electric current produces magnetic field in coil 12.The form of implementation of have coil (magnet exciting coil) and magnetic core is shown to Fig. 1 and 2 example, but wherein can be provided with a plurality of coils of coil 12 or the coil of forming by several parts equally, and can be provided with in addition a plurality of or form by several parts and interconnective magnetic core as magnetic core 11.
For the operating device 14 that makes magnetic core 11 arrive predetermined resting positions and therefore to be permanently connected with magnetic core 11 also arrives predetermined resting position, be provided with the 3rd spring 15, described spring applies prestressing force towards the resting position direction of magnetic core on magnetic core.According to the diagram in Fig. 1, the prestressing force that produces by the 3rd spring 15 along the longitudinal direction of magnetic core 11 and operating device 14 left.
Therefore according to the diagram in Fig. 1 and 2, switch body 1 together with Key element 2, touch bridge shape contact chip support 3, the control piece 8 that touches bridge shape contact chip 4 and a plurality of contact element 5 and switch element SE also has the magnetic core 11 of switching units AE can to move along the longitudinal axis of oneself together with operating device 14, wherein applying corresponding prestressing force on the parts by spring (be first spring 9 and second spring 10 of switch element SE, and the 3rd spring 15 of switching units AE) accordingly along preferred direction respectively in Fig. 1 and 2.
The following describes the function and the working method of switching device with switch element SE and switching units AE.
Switch element SE shown in the diagram in Fig. 2 in following structure, a plurality of contact elements 5 separate with fixing contact element 6 on fixing contact element support 7 in described structure, and described a plurality of contact elements 5 are arranged on to form on touching bridge shape contact chip 4 and touching bridge shape contact chip support 3, switch body 1 and Key element 2 by it and movably contact.Circuit is disconnected in this case, and in view of moving along the possible of its corresponding longitudinal direction, and switch body 1 (together with Key element 2, touch bridge shape contact chip support 3 and touch bridge shape contact chip 4) and control piece 8 are positioned at corresponding primary importance.Position above being positioned in the diagram of primary importance in Fig. 2 of switch body 1 (together with other fixed thereon parts 2,3,4 and 5), and the primary importance of control piece 8 is positioned at the position on right side according to the diagram in Fig. 2.
If now by the user against the prestressing force of first spring 9 with the Key element among Fig. 22 to the mode that presses down, user's master cock device and especially master cock cell S E are so that open (connection) circuit, so by switch body 1, Key element 2, touch bridge shape contact chip support 3 and have under contact element 5 touch structure that bridge shape contact chip 4 forms against moving down in the spring force of first spring 9 or the diagram of prestressing force in Fig. 2, make contact element 5 (movably) contact and flexibly be close to the contact element of fixing 6.Connect circuit in such a way in the way you want, and switch body 1 arrives its second place with other disposed thereon parts.
If in moving by user's operating buttons element 2 time, move to its second place (below) according to Fig. 2 switch body 1 from its primary importance (in the above), so the prestressing force of second spring 10 in Fig. 1 and 2 along left directive effect on control piece 8, control piece 8 is moved to the left to its second place from its primary importance (right side among Fig. 1 and 2), wherein be arranged on the control piece 8 of switch element SE and groove 17 that the side towards pin 16 that arrive switch body 1 from the pin 16 that control piece protrudes constitutes in and so can hold the engage grooves of pin with this.If the pin 16 of control piece 8 vertically moves in the groove 17 that arrives switch body 1 accordingly by switch body 1 and control piece 8, pin 16 occupies stable position in groove 17 so, make switch body in Fig. 1 and 2 along aspect vertical direction possible mobile, the joint of the pin 16 by control piece 8 and together with the fixing and maintained switch body 1 of the prestressing force of effect left in Fig. 1 and 2 of second spring 10.
Switch body 1 and control piece 8 mechanically block on the position that all is the corresponding second place for two parts mutually.Therefore switch body 1 and control piece 8 machinery by pin 16 and groove 17 engage and the corresponding prestressing force of first and second springs 9 and 10 remains on their the corresponding second place.
By this locking, the parts of switch body 1 and disposed thereon other, especially contact element 5, and its position of prestressing force maintenance against first spring 9 makes and connects circuit with stable manner reliably by a plurality of (movably) contact element 5 and fixing a plurality of contact elements 6.
If now by existing predetermined disconnection condition (being used to make the outage condition of switching device outage) and this by unshowned valuation device and control device identification aspect the switching units AE aspect the switching device and especially, supply with the coil 12 corresponding electric currents of switching units AE so by electric wire 13, make coil 12 can form corresponding magnetic field, described magnetic field directly acts on the magnetic core 11 and therefore and also acts on the operating device 14.
If form magnetic field together with power supply by coil 12, so magnetic core 11 (together with the operating device 14 that is fixed on the magnetic core 11) beginning against in the diagram of prestressing force in Fig. 1 and 2 of the 3rd spring 15 to the right the direction towards control piece 8 move.
If at this moment control piece 8 and switch body 1 are positioned at their the corresponding second place, as shown in FIG. 1 and wherein the pin 16 of control piece 8 reaches with the groove 17 that correspondingly is provided with in switch body 1 and contacts, and magnetic core 11 and be installed in the operating device 14 on the magnetic core 11 because the prestressing force by the 3rd spring 15 is arranged on their resting position (in the diagram of Fig. 1 in the leftmost side), have predetermined distance D so between the left end of the right-hand member of operating device 14 and control piece 8, described operating device 14 and control piece 8 are being positioned on the common straight line and can moving along this straight line on their longitudinal direction.
If according to as above explanation, by means of the magnetic field that produces by coil 12, magnetic core 11 moves right according to the diagram in Fig. 1, and therefore operating device 14 moves right in the same way, and so interconnective parts (magnetic core 11 and operating device 14) produce acceleration towards the direction of control piece 8 along predetermined distance D.This means, through during the moving of predetermined distance D, magnetic core 11 and operating device 14 quicken by the power that is applied by magnetic field and therefore absorb kinetic energy, make the magnetic core 11 of switching units AE run into the left end of control piece 8 together with operating device 14 after overcoming predetermined distance D and produce collision on control piece 8.Flexible basically collision with the predetermined kinetic energy of physical dimension by the element that relates to is relevant with the material of use, make almost entirely to be delivered on the control piece 8 that at this moment described control piece is arranged in its second place (at Fig. 1 and 2 in the left side) and therefore is in by pin 16 and groove 17 and switch body 1 blocking at the kinetic energy of magnetic core 11 together with the storage of accelerating period of the predetermined distance D of process of operating device 14.Switch body 1 is arranged in its second place (at Fig. 1 and 2 below, connecting circuit) equally.
If magnetic core 11 produces (mainly being flexible) collision together with operating device 14 by predetermined kinetic energy on control piece 8, control piece 8 is moved right against the generation prestressing force (prestress square is to left in Fig. 1 and 2) by second spring 10 or move, make because magnetic core 11 by switching units AE and operating device 14 are delivered to the kinetic energy on the control piece 8, the pin 16 of control piece 8 can leave prior stable position in the groove 17 of switch body 1 together with control piece 8, and then control piece 8 moves towards the direction of its primary importance to the right according to the diagram among Fig. 1 and 2.Because by because the moving of the control piece 8 of magnetic core 11 by switching units AE and operating device 14 collision to the right, opened the mechanical latching of control piece 8 with switch body 1, so prestressing force by first spring 9, switch body 1 is together with touching bridge shape contact chip 4, a plurality of contact element 5, touching bridge shape contact chip support 3 and Key element 2 and move up according to the diagram in Fig. 1 and 2, makes a plurality of (movably) contact element 5 no longer touch a plurality of fixing contact elements 6 and therefore open circuit.Therefore switch body 1 occupies its primary importance (cut-out switch element) again in the parts of disposed thereon other, and wherein control piece 8 is same arrives its primary importances (in Fig. 1 and 2 on the right side) and the pin 16 of control piece 8 abuts against switch body 1 by the prestressing force of second spring 10 on this position side (Fig. 2).
After by generation collision on the control piece 8 of operating device 14 of switching units AE at switch element SE, then cut off to the power supply of the coil 12 of switching units AE and cut off the magnetic field that therefore produces of magnetic core 11 and therefore same operating device 14 by get back to resting position (home position) by the prestressing force of the 3rd spring 15, be positioned at the left side according to the described resting position of the diagram in Fig. 1 and 2.
Being in stable blocking by this way throws off with the switch element SE that is in on-state and therefore disconnection.Circuit is disconnected.Control piece 8 and switch body 1 are got back to their corresponding primary importance.Specifically, therefore the control piece 8 of switch element SE and switch body 1 have corresponding first and second positions, and the described first and second position phase mutual coupling join and can reach mutually by relatively moving.
By the predetermined distance D between the control piece 8 of the operating device 14 of switching units AE and switch element SE, possible is, even be used for less power and be provided with (determining size) switching units AE of the physical dimension that reduces and the weight that alleviates, also guarantee to be switched on or switched off reliably, because for cut-off switch cell S E, switching units AE also can produce enough big collision by predetermined distance D on the control piece 8 of switch element SE in the more weak magnetic field of coil 12.
When the predetermined distance D of process moves when magnetic core 11 constitutes magnetic field in coil 12 during, through predetermined distance D during this period of time during the acceleration that reaches realize storing predetermined kinetic energy together with operating device 14 by magnetic core 11, make and guarantee effectively and disconnect reliably or outage.On the control piece that is combined in switch element SE 8 in moving by being in of magnetic core 11 and operating device 14 almost mainly is elastic collision, the whole kinetic energy that absorb from parts 11 and 14 quicken are delivered on the control piece 8, although make and in the groove 17 of the switch body 1 of switch element SE (second place), have stable position against the prestressing force of second spring 10 and the pin 16 of control piece 8, but also can throw off and therefore control piece 8 can move to its primary importance (open circuit, the diagram in Fig. 2) from its second place.
In order to absorb enough kinetic energy during moving predetermined distance D at least, magnetic core 11 preferably constitutes flywheel mass.Because having the switching units AE of the magnetic core 11 with lifting magnet function is arranged to, make and between operating device 14 and control piece 8, have predetermined distance D, begin when mobile at magnetic core 11, just the flywheel mass that comprises operating device 14 of magnetic core 11 must be quickened by the magnetic field that constitutes in coil 12, make magnetic core 11 and operating device 14 all-mass (flywheel mass) control piece 8 is thrown off from the stable second place that it is equivalent to resting position, so that switch body 1 can be got back to its primary importance (among Fig. 1 and 2 in the above) from its second place equally subsequently, thereby open circuit.
In Fig. 1 and 2, show moving of each parts (switch body 1, control piece 8 and have the magnetic core 11 of operating device 14) by arrow.
For cut-off switch device and especially cut-off switch cell S E, detect disconnection condition (outage condition) according to Fig. 1 and 2 needs.Therefore specifically, when switching device is in the state of connection, must determine whether to exist predetermined disconnection condition.If there is predetermined disconnection condition, for the disconnection process is begun, give coil 12 power supplies so by electric wire 13.
The disconnection condition for example can be predetermined fault situation, overcurrent, overvoltage or suchlike situation, wherein after detecting defective situation, provides corresponding electric current so that cut-off switch cell S E to the coil 12 of switching units AE.Therefore this corresponding electric current can have the function of cut-off signal (AUS signal), and switching device is used as protection switch.
But in household electrical appliance, also can be provided with the switching device that has switch element SE and switching units AE according to of the present invention, for example washing machine or dryer wherein can be connected circuit and therefore connect this equipment by means of the Key element 2 of master cock device by the user after connection.If the measure that finishes running or stop determining according to the predetermined running of equipment can disconnect the switching device with switch element SE and therefore cut off power supply to equipment so in automatic mode.
In the structure in household electrical appliance according to switching device of the present invention, for example in washing machine or dryer, possible is, provide undersized and therefore switching units AE cheaply by the structure with predetermined distance D that specifies above, described switching units can also cause disconnecting effectively and therefore cause closing device reliably.Advantageously, this makes whole switching device have less size.
Do not come closing device fully if do not consider the existence of disconnection condition (outage condition) from user's aspect, can be provided with other switching mechanism (button so equally, not shown), after by user's manual control, power for the coil 12 of switching units AE by means of described switching mechanism, make that (switch body 1 and control piece 8 are positioned at their the corresponding second place) can also be by being undertaken by user's manual control except the possibility of above-mentioned automatic outage under the situation of the equipment of connection in predetermined mode.
Therefore in principle under the situation of quickening (by the power supply of coil 12), the direction towards control piece 8 at magnetic core 11 and operating device 14 is passed through received pulse size or pulse power on the route of predetermined distance D, described impulse magnitude or pulse power are by means of producing by the collision of operating device 14 on control piece 8, wherein, be provided with the less electric energy (electric current) of the coil 12 that is used for switching units AE together with route through the predetermined at least distance D that is used to quicken magnetic core 11 and operating device 14.This electric energy or power supply that is used for the coil 12 of switching units AE especially can continue the predetermined time.The accelerating period through predetermined at least distance D at magnetic core 11 and operating device 14 has stored enough kinetic energy, so that cause the effective of switch element SE and disconnect (outage) reliably.Under currentless state, that is to say that because the prestressing force of spring 15, magnetic core 11 is got back to its (being provided with in the left side) resting position together with operating device 14 in Fig. 1 under the situation of the outage of the coil 12 of switching units AE.
In the diagram in Fig. 1 and 2, to connect or separate in order to produce in circuit, switch element SE one pole ground constitutes.But the switching device with switch element SE according to the present invention also can constitute multipolely and therefore be used for a large amount of circuit.
The correspondingly mobile alignment of parts movably as control piece 8, switch body 1 and magnetic core 11 (together with corresponding other parts disposed thereon), guided linearly and by the restriction of corresponding backstop, yet wherein in order to be reduced at the not shown backstop of diagram among Fig. 1 and 2.
With compare from solution well known in the prior art, need not begin within the scope of the invention that (together with operating device 14) applies big power when mobile at magnetic core 11, described power needs under following situation, promptly when between the operating device 14 of the control piece 8 of switch element SE and switching units AE, be not provided with predetermined apart from the time, but operating device 14 under static state also is close on the control piece 8 and when moving of the process of disconnection also must make control piece 8 quicken at first immediately.Therefore just apply less power by switching units AE together with coil 12 and the electric current of supplying with this coil 12 according to the present invention, described power can be through the magnetic core 11 of the accelerated period chien shih switching units AE of predetermined distance D and the kinetic energy that operating device 14 obtains enough to be used to the process that disconnects.Therefore only on the magnetic core 11 of switching units AE and operating device 14 effect directly quicken.
Above-mentioned switching device with switch element SE and switching units AE can use together with stand-by state control device (Standby control device) equally.Can limit the disconnection standard by the stand-by state control device in this case, so based on described disconnection standard cut-off switch device in the above described manner.Especially can automatically carry out the transition to currentless state from stand-by state with low-power consumption, for example according to waiting time, under described currentless state, exist or satisfied disconnection condition (outage standard) back in the past, make switching device automatically disconnect and equipment is transformed into currentless state then in waiting time.
In addition when program stops needing automatically to disconnect (outage) under back or the situation in the running status of determining of detection computations equipment machine or to be monitored or to be controlled, also can be together with computer equipment (electronic data processing, personal computer, master computer, server and suchlike computer equipment) generation disconnection condition.Can disconnect reliably by the switching device that above-mentioned having has a switching units AE of lower-wattage.
Below with reference to the Fig. 3 and the 4 explanation second embodiment of the present invention.
If corresponding parts are carried out identical functions basically, so at Fig. 3 and the parts shown in 4 with switch element SE and switching device of switching units AE by indicating with the identical reference marker in Fig. 1 and 2.
