Abstract
A kind of new type electric leakageproof device, is characterized in that: the bottom of the column part of its button is provided with narrow groove and a ramp down limit, place together, and slide plate under spring force, is inserted in the narrow groove of button; Firmly button press, button is moved down together by slide plate band movable slider, until snap close is by slider locks release-push behind the relevant position of contact closure, due to the restriction by slide plate, button rests on the relevant position of contact closure with slide block.During opening operation, trip between snap close and slide block, button upwards will spring back to initial position.The button of this earth leakage protective device is when switch closed condition and off-state, and the position of the position that button stops and switch contact exists corresponding relation.Further, now press button again, contact also can not produce the interim phenomenon disconnected.
Description
Technical field
The utility model relates to appliance switch and the socket of the relevant earth leakage protective aspect in electrical engineering and electric apparatus field, particularly relates to the switch on wall of the mobile jack of band creepage protection function, the band plug of creepage protection function, the earth leakage protective of electric heating appliance and band creepage protection function.
Background technology
At present, the earth leakage protective devices such as the leakage protecting plug on market, socket mainly contain two kinds:
One utilizes button down to press itself and snap close are locked, and meanwhile, makes button spring energy storage, and after the power release of pressing button, button makes contact closure by snap close and other mechanism member under the counter-force effect of button spring; When triping between button and snap close, button in the effect spring-go position next time of button spring, moving contact and fixed contact separated.This earth leakage protective device has some defects, respectively:
1) power needed for contact closure comes from button spring; Required operating physical force is relatively large.
2) position of button when off-state and closure state is different, but position difference is not obvious, and this difference value is uncertain; If indicated by the state of this position difference as switch, can only be passable reluctantly.
3) if press button under switch closed condition, contact there will be and disconnects phenomenon temporarily.
Another kind is firm incipient a kind of new type electric leakageproof device on market, it solve some major defects of the first type earth leakage protective device, switching manipulation power has suitable reduction, push switch button under closure state, and contact there will not be the interim phenomenon disconnected; But the position of switch key when switch closes and separate of the earth leakage protective device of that type does not change, and only has the change of operating physical force size, cannot indicator cock be directly so just at closure state or in off-state.
Summary of the invention
In view of the above-mentioned defect that this two classes earth leakage protective device exists separately, the utility model provides a kind of scheme, and it has following characteristics:
1) can the obviously off-state of indicator cock device and closure state.
2) at closure state pressing button, contact there will not be the advantages such as interim disconnection phenomenon.
It avoids the defect of above-mentioned two series products in the market, combines the advantage of above-mentioned two series products.
The scheme of the utility model earth leakage protective device is: a kind of new type electric leakageproof device, also comprises: snap close, slide block, button, slide plate etc.It is characterized in that: described snap close is arranged on a support; The bottom of the column part of described button is provided with narrow groove and a ramp down limit, place together, and when initial condition, slide plate under spring force, is inserted in the narrow groove of button; Exert oneself when switch needs closed button press, button is moved down together with slide plate band movable slider by the face of the top of narrow groove, until snap close is by the relevant position of slider locks in contact closure, switch completes closed procedure; During release-push, because slide plate is to the restriction in the face below the narrow groove of button, along with slide block rests on the relevant position of contact closure together.Now, if press button contacts more also can not produce the interim phenomenon disconnected.
During opening operation, snap close can be pulled open, make to trip between snap close and slide block, button will with slide block, contact etc., and upwards resilience under spring force, completes disconnection action together.Button also gets back to initial position thereupon, and there is change clearly the position that the button of button when switch closed condition and off-state of this earth leakage protective device stops, is enough to indicating on-off state.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment earth leakage protective device;
Fig. 2 is the stereogram of the utility model embodiment button
Fig. 3 is the stereogram of the utility model embodiment slide block
Fig. 4 is the stereogram of the utility model embodiment slide plate
In figure, shown in mark, parts title is as follows:
Face below face, 3012 above 1 snap close, 2 slide blocks, 3 buttons, 301 narrow grooves, 302 ramp down limits, 3011,4 slide plates.
Embodiment
The earth leakage protective device structure of the utility model embodiment is as Fig. 1, and a kind of earth leakage protective device, also comprises: snap close 1, slide block 2, button 3, slide plate 4.
It is characterized in that: described snap close 1 is arranged on a support; The bottom of the column part of described button 3 is provided with narrow groove 301 and a ramp down limit, place 302 together, and when initial condition, slide plate 4 under spring force, is inserted in the narrow groove 301 of button 3; Exert oneself when switch needs closed button press 3, button 3 to be with together with movable slider 2 with slide plate 4 by the face 3011 of the top of narrow groove 301 and to be moved down, until slide block 2 is locked in the relevant position of contact closure by snap close 1, switch completes closed procedure; During release-push 3, due to the restriction in the face 3012 below the narrow groove 301 of slide plate 4 pairs of buttons 3, along with slide block 2 rests on the relevant position of contact closure together.Now, if press button 3 contact more also can not produce the interim phenomenon disconnected.
During opening operation, snap close 1 can be pulled open, make to trip between snap close 1 and slide block 2, button 3 will with slide block 2, contact etc., and upwards resilience under spring force together, completes disconnection action.Button 3 also gets back to initial position thereupon.
Therefore, there is relation one to one between the position of button 3 and the position of switch contact, be enough to the closure state and the off-state that are used to refer to switch.
Claims (2)
1. a new type electric leakageproof device, also comprises: snap close (1), slide block (2), button (3), slide plate (4); It is characterized in that: described snap close (1) is arranged on a support; The bottom of the column part of described button (3) is provided with narrow groove (301) and a ramp down limit, place (302) together, when initial condition, slide plate (4) under spring force, is inserted in the narrow groove (301) of button (3); When switch needs closed, firmly button press (3), button (3) is moved down, until slide block (2) is locked in the relevant position of contact closure by snap close (1) together by the face (3011) of the top of narrow groove (301) and slide plate (4) band movable slider (2); Time release-push (3), because slide plate (4) is to the restriction in the face (3012) of narrow groove (301) below of button (3), button (3) rests on the relevant position of contact closure with slide block (2); During opening operation, make to trip between snap close (1) and slide block (2), button (3) upwards will spring back to initial position; Corresponding relation is there is between the position of button (3) and the position of switch contact.
2. new type electric leakageproof device according to claim 1, is characterized in that: the bottom of the column part of described button (3) is provided with narrow groove (301) and a ramp down limit, place (302) together.
