Description

Energy-saving electric switch

The utility model relates to a kind of mains switch.

At present, various in style, the diverse in function of the switch on the market.The switch of some electronic control, the Push And Release of its movable contact spring do work by other equipment and realize, and majority is to make iron core drive movable contact spring by solenoid to swing, finish power on/off.But the shortcoming of this switch is a switch will switch on the time, must allow solenoid also switch on to guarantee that the iron core in the solenoid keeps in touch movable contact spring and fixed touching plate always always, solenoid is in long-time energising like this, wastes a large amount of electric energy, and easily heating causes security incident.

The purpose of this utility model is to provide a kind of need to provide of short duration energising just can realize that switch often leaves or normally closed energy-saving electric switch in order to overcome above-mentioned shortcoming.

The purpose of this utility model can be achieved as follows: this energy-saving electric switch, mainly form by switch pedestal, button, fixed touching plate and movable contact spring, it is characterized in that: the closure of movable contact spring and fixed touching plate and off-state are passed through closed controlling organization respectively and are disconnected controlling organization control, and closed or disconnection controlling organization is mainly driven by the iron core of solenoid.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is the structural representation of a kind of execution mode of the utility model energy-saving electric switch;

Fig. 2 is the structural representation of the another kind of execution mode of the utility model energy-saving electric switch.

In Fig. 1, show wherein a kind of execution mode of energy-saving electric switch, solenoid 41 is flatly solid on base 1,51 fens two parts unshakable in one's determination, become stepped, its external diameter of part that external diameter is big and length and solenoid 41 adapt, and place in the solenoid 41, and its end of part that external diameter is little and movable contact spring 3 flexibly connect for the hinge formula.Movable contact spring upper end is that the hinge formula flexibly connects with base, and its left side, lower end is the contact, and corresponding with the contact of fixed touching plate 2 on being fixed on base, the right side then is connected with spring 61, and the spring other end links to each other with base.Solenoid 42 is positioned at the lower left of solenoid 41, heavily fortified point directly is fixed on the base, unshakable in one's determination 52 lower end is connected with spring 62, and the upper end is a wedge shape, and length unshakable in one's determination should guarantee that at least under the spring force effect its wedge grip can contact the surface of 51 external diameter fractions unshakable in one's determination.Relative position between the solenoid 41 and 42 should satisfy unshakable in one's determination 52 and can move back and forth up and down near before the left end of solenoid 41.During work, press the button of solenoid 42 and connect its power supply, 52 elastic force that overcome spring 62 under the electromagnetic force effect unshakable in one's determination move downward, when the wedge grip of 52 upper ends unshakable in one's determination moves to the below of the big part of unshakable in one's determination 51 external diameter, unshakable in one's determination 51 owing to do not had for unshakable in one's determination 52 stop, at this moment movable contact spring in the elastic force effect of the spring 61 of its lower end to moving to left, it is fixed to make, the engage contacts of movable contact spring together, driving unshakable in one's determination 51 simultaneously moves to left, because the effect of spring 61 is arranged, even the power supply of cutoff solenoid 42 at this moment, fixed, the contact of movable contact spring still can keep on-state, Here it is described closed controlling organization only needs solenoid 42 of short duration energisings, and contact that just can switch reaches normally closed purpose.When switch is disconnected, only need to give solenoid 41 energisings, at this moment unshakable in one's determination 51 under the electromagnetic force effect, move right, and put to the right on drive movable contact spring limit compression spring 61 limits, it is fixed to make, the contact of movable contact spring is gradually separately until separating fully, along with unshakable in one's determination 51 constantly past moving to right, in the time of in the big part of 51 external diameters unshakable in one's determination is submerged solenoid 41 fully, originally the wedge grip that was pressed on the iron core 52 on its surface upwards moves under the effect of spring 62 and becomes the surface that is pressed on the little part of 51 external diameters unshakable in one's determination, when cutting off the power supply of solenoid 41, owing to lost electromagnetic force, unshakable in one's determination 51 under the acting in conjunction of spring 61 and movable contact spring again to moving to left, but unshakable in one's determination 52 wedge grip will stop it to move to left, it is fixed to make, the contact of movable contact spring remains in released state, Here it is described disconnection controlling organization is only to need provide of short duration energising can realize the purpose that switch often leaves to solenoid 51 equally.

In the foregoing description, movable contact spring can be connected with base and directly be fixed on unshakable in one's determination 51 left end, and spring 61 becomes with the right-hand member of iron core 51 and is connected simultaneously, can reach above-mentioned effect equally.Solenoid 41 and 42 relative position are except can placing in a manner described, can also place solenoid 42 with other angles at arbitrary end of solenoid, as long as can satisfy the iron core 51 when contact separation by fastening at certain position, the rest may be inferred, iron core 51 is also not necessarily leaveed no choice but stepped, as opening a groove, can reach purpose equally on its left-half surface.In addition, the wedge grip of 52 upper ends unshakable in one's determination mainly is for reducing friction resistance and be beneficial to unshakable in one's determination 51 move to right, as long as can satisfy this, adopting other shapes also to be fine.In a word, shape that each several part adopted among the embodiment and structure purpose are in order to reach often opening and the just energising momently of normally closed and solenoid of switch.

In Fig. 2, show another execution mode of energy-saving electric switch, the lower end of movable contact spring 3 and base flexibly connect for the hinge formula, and the left and right sides of about medium position is the flexible connection of hinge formula with unshakable in one's determination 51 and 52 respectively, and solenoid 41 and 42 is fixed on the base in parallel to each other.When solenoid 41 energisings, unshakable in one's determination 51 to moving to left, drive the movable contact spring pendulum of turning left, when putting the upright position, engage with fixed touching plate on being fixed on base, fixed touching plate is the sleeve that two copper sheets become the slit port shape, movable contact spring there is certain chucking power, at this moment cut off the power supply of solenoid 41, then switch is kept closed, and this closure controlling organization has reached equally only needs the of short duration energising of solenoid just can make the normally closed purpose of switch.When solenoid 42 energisings, unshakable in one's determination 52 move right, drive movable contact spring and turn right pendulum and break away from fixed touching plate, the solenoid outage, then switch is in off-state, Here it is described disconnection controlling organization, certainly, also need establish a shell fragment (not shown) near the left port of solenoid 42, purpose is when switch disconnects, prevent that unshakable in one's determination about 52 move freely and movable contact spring is got back to the fixed touching plate position, the elastic force of this shell fragment should be able to be overcome by the electromagnetic force of solenoid 41.Perhaps add a fixed touching plate, make movable contact spring between two fixed touching plates, can realize position-limiting action equally, and can be used as the ganged switch use.

Above-mentioned two embodiment only show two kinds of typical structures, can also design the closed and disconnected controlling organization with other version certainly, so long as utilized principle of the present utility model, also should belong within the utility model protection range.

Owing to only need to give the of short duration energising of solenoid, just can realize the normally closed of switch and often open by the closed and disconnected controlling organization, avoided long-time supply power to come control switch, save the big and often long-time electric equipment that operates of a large amount of electric power resources, particularly power, its advantage is more outstanding, and solenoid is difficult for heating, fail safe is good, therefore, is worthy of popularization very much.
