Abstract
The utility model relates to an over-current protection switch, which comprises a casing (1). Three safety pins are arranged on the bottom of the casing, and a switching push-button (2) is equipped on the top of the casing. A spring (3) is mounted on the lower of the switching push-button and is sleeved on a moving-strip (10) with contact, and the moving-strip (10) is contacted with a safety pin (11). One side of the moving-strip is disposed with a block (1-1) which is arranged by the casing, and the other side is provided with a stator with contact which is connected with a bimetal strip (5). The contact of the bimetal strip (5) is contacted with a safety pin (13) through a hole (16-1) in a return strip (16), a spring (6) is arranged between the return strip (16) and the casing, and the return strip is higher than the casing (1) when jumping. A resistance (8) and an indicating lamp (7) are connected in series between safety pins (9) (11). The utility model is designed reasonably, and has the advantages that the light is displayed when online, the breakdown of state is indicated, and the return can be finished by hands.
Description
Technical field
The utility model relates to a kind of electric switch, mainly is a kind of overcurrent protection switch.
Background technology
Chinese patent ZL98241751.9 discloses a kind of " discharge cock ", and it has a housing, and release knob is arranged on the housing, and release knob control switch parts have three pins under the housing, and one of them pin is connected with bimetal leaf.When the circuit overcurrent, the bimetal leaf tripping is cut off the electricity supply, and plays the protection switch effect.But this switch has some not enough: the one, and fault generation stateless shows, and is unfavorable in safety; The 2nd, fault can only wait for that it automatically resets after getting rid of, and can't carry out Artificial Control; The 3rd, there is not the lamp indication at wiretap, influence is used.
Summary of the invention
The problem that the utility model need solve is, overcomes disadvantages of background technology, and providing a kind of onlinely has light to show, fault has state to show, and overcurrent protection switch that can hand-reset.
Overcurrent protection switch of the present utility model has a housing, and release knob is arranged on the housing, and release knob control switch parts have three pins under the housing, and one of them pin is connected with bimetal leaf, it is characterized in that having the reset components of reseting plate control.Described switch block is, under the release knob spring arranged, and spring housing is having on the moving plate of contact, and moving plate contacts with pin; One side of moving plate is that the set block another side of housing is the stator that contact is arranged, and stator is connected with bimetal leaf; The contact of bimetal leaf contacts with the contact of pin by the hole in the reseting plate; These parts can control switch on off operating mode.Described reset components is, between reseting plate and the housing spring arranged, and reseting plate is higher than housing when upspringing.Can be serially connected with resistance and indicator light between two pins, to give online switch with indication.
The utility model is reasonable in design, and having onlinely has light to show, fault has state to show, and advantage that can hand-reset.
Description of drawings
Fig. 1 is that master of the present utility model looks schematic diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Embodiment 1.See Fig. 1, this routine overcurrent protection switch has a housing 1, two districts about housing divides.There is the switch block of release knob 2 controls in left side district: release knob has spring 32 times, and spring 3 is enclosed within on the moving plate 10 of contact, and moving plate 10 contacts with pin 11; One side of moving plate is the set block 1-1 of housing, and another side is the stator 4 that contact is arranged, and stator 4 is connected with bimetal leaf 5; The contact of bimetal leaf 5 is connected with the contact of pin 13 by the hole 16-1 in the reseting plate 16; Be serially connected with resistance 8 and indicator light 7 between the pin 9 and 11.There is the reset components of reseting plate 16 controls in right district: between reseting plate 16 and the housing 1 spring 6 is arranged, reseting plate is higher than housing 1 when upspringing.
During use, release knob 2 is in the bottom right, and moving plate 10 left sides tiltedly contact with the contact of stator, and pin 11, moving plate 10, stator 4, bimetal leaf 5 and pin 13 are formed loop, switch conduction.When the circuit overcurrent, bimetal leaf 5 heated bendings distortion is thrown off with pin 13 and is cut off the electricity supply, and reseting plate 16 is upspring under the effect of spring 6 (contact hole 16-1 rises simultaneously) simultaneously, gives the demonstration of being out of order; Because the rising of contact hole 16-1, the sheet that is reset all the time between bimetal leaf 5 and the pin 13 is isolated, and off-position will remain to fault to be got rid of, and just finishes when pressing reseting plate 16.When need cutting off switch, a left side touches the button, and moving plate 10 is close to block 1-1, and its contact separates, off state.When switch was online, indicator light was lighted all the time, very intuitive and convenient.
Claims (3)
1, a kind of overcurrent protection switch has a housing (1), and release knob (2) is arranged on the housing, and release knob control switch parts have three pins under the housing, and one of them pin is connected with bimetal leaf, it is characterized in that reseting plate is arranged (16) control reset components.
2, overcurrent protection switch according to claim 1 is characterized in that described switch block is, spring (3) is arranged under the release knob (2), and spring (3) is enclosed within on the moving plate (10) of contact, and moving plate (10) contacts with pin (11); One side of moving plate is the set block of housing (1-1), and another side is the stator (4) that contact is arranged, and stator (4) is connected with bimetal leaf (5); The contact of bimetal leaf (5) contacts with the contact of pin (13) by the hole (16-1) in the reseting plate (16); Described reset components is, between reseting plate (16) and the housing (1) spring (6) arranged, and reseting plate is higher than housing (1) when upspringing.
3, overcurrent protection switch according to claim 1 and 2 is characterized in that being serially connected with between described pin (9) and (11) resistance (8) and indicator light (7).
