Abstract
The utility model relates to a key-type tripping device, which is composed of a button pressing rod, a lock bolt and an electromagnet, wherein, a lock catch and a reset spring are arranged on the button pressing rod; the lock bolt is inserted into the lock catch under the action of a spring of the lock bolt to lock the button pressing rod. When a rated current flows into an electromagnet coil, magnetic force is generated to pull the lock bolt out of the lock catch, releasing locking state; the button pressing rod is subjected to the elastic force of the reset spring to be ejected in time, and thus a contact is broken. The device has the advantages of small size and simple structure, and is suitable for various circuit breakers and electric-leakage protective switches.
Description
The utility model relates to the breaker device in a kind of Protector for electric appliances, is a kind of button trip gear specifically.
At present, in order to prevent the generation of electric leakage accident, power supply department requires every household that earth leakage circuit-breaker must be installed, and the trip gear in the earth leakage circuit-breaker generally adopts the handle dial type, this complex structure, and volume is big, the cost height.Recently; disclosed a kind of " leakage protecting plug " utility model patent; its notification number is CN 2184993Y, and the tripping mechanism device of this leakage protecting plug is characterised in that: by strong depression bar lower end a guide hole identical shaped with the movable tip is arranged, the movable tip can horizontally slip.There is stage clip the depression bar lower end, and an end of the movable tip has the U type connecting plate of middle trough of belt, and an end of movable core I-shaped groove can upper and lower slip in the groove of the movable tip, and the other end of the movable tip has the limiting plate and the press strip of dentation.When pressing down when strong, move down by strong depression bar, the drive activity tip is depressed the contact pressing plate, the contact of upper and lower contact, at this moment, the limiting plate of the movable tip relies on self-locking spring to make the depression bar location, and the required pressure in upper and lower contact relies on the contact pressing plate to reach the elastic force of going up contact and provides.This structure has solved above-mentioned bulky problem, needs to make a complex structure and the accurate movable tip but also deposit, and causes the high shortcoming of cost.
The utility model provide a kind of volume little, simple in structure, can be advantageously used in button trip gear on various circuit breakers, the earth leakage circuit-breaker again.
The purpose of this utility model is achieved in that the button trip gear is by forming by button press bar, locking bolt, electromagnet.Be provided with snap close by button press bar, the lower end heads on moving contact, by also being provided with back-moving spring on the button press bar.When hand presses the button depression bar, move down by button press bar, moving contact is depressed and fixed contact closure, switch ways.At this moment, locking bolt inserts snap close and will lock by button press bar under the effect of locking bolt spring, back-moving spring is depressed energy storage, when electromagnet coil flows into rated current, coil produces powerful magnetic force pulling locking bolt and moves toward coil direction, and locking bolt withdraws from snap close, and state unlocks, in time upspring by the elastic force of back-moving spring by button press bar, the contact disconnects.
Owing to adopt above-mentioned technical scheme, make the button trip gear realize that volume is little, simple in structure, can be applicable to various circuit breakers, earth leakage circuit-breaker easily again.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the schematic diagram of the another kind of structure of the utility model.
Shown in 1 figure, the utility model button trip gear is by forming by button press bar 2, locking bolt 4, electromagnet 6.Be provided with snap close 3 by button press bar 2, the lower end heads on moving contact 8, by also being provided with back-moving spring 1 on the button press bar 2.When pressing the button depression bar 2, move down by button press bar 2 moving contact 8 is depressed and fixed contact 9 closures, switch ways.At this moment, locking bolt 4 under the effect of locking bolt spring 5, insert snap close 3 will be by button press bar 2 locking.Back-moving spring 1 is depressed energy storage.Because locking bolt 4 is to make moulding with magnetic conductive metal, with the lower end is that fulcrum rotates, when electromagnet 6 flows into rated current, coil produces powerful magnetic force pulling locking bolt 4 and rotates toward coil direction, locking bolt 4 withdraws from snap close 3, the state that unlocks is in time upspring by the elastic force effect of back-moving spring 1 by button press bar 2, the contact disconnects.
Another kind of structure as shown in Figure 2, movable core 7 is installed in and can moves flexibly sewing in the spool of electromagnet coil, an end of movable core 7 is provided with locking bolt 4, to pressing button press bar 2, past coil direction moves under the effect of electromagnetic force following of the effect of locking bolt spring 5.Become snap close 3 by breach is set on the button press bar 2, the lower end heads on moving contact 8, by also being provided with back-moving spring 1 on the button press bar 2.When pressing the button depression bar 2, move down by button press bar 2 moving contact 8 is depressed and fixed contact 9 closures, switch ways.At this moment, locking bolt 4 inserts snap close 3 together with movable core 7 under the effect of locking bolt spring 5 will be by button press bar 2 lockings, and back-moving spring 1 is depressed energy storage.When electromagnet coil flows into rated current, produce powerful magnetic force movable core 7 is moved toward coil direction together with locking bolt 4, locking bolt 4 withdraws from snap close 3, and the state that unlocks is in time upspring by the elastic force effect of back-moving spring 1 by button press bar 2, and the contact disconnects.
Claims (5)
1, a kind of button trip gear, by forming by button press bar, locking bolt, electromagnet, be provided with resetting means by button press bar, the lower end heads on moving contact, can move up and down by button press bar, with moving contact and fixed contact disconnection or closed, it is characterized in that: by also being provided with snap close on the button press bar, locking bolt inserts snap close and will lock by button press bar under the effect of locking bolt spring, contact closure, locking bolt withdraws from snap close when the magnetic attraction of electromagnet, disengage button depression bar lock-out state, and contact disconnects.
2, button trip gear according to claim 1, it is characterized in that: locking bolt is to make moulding with magnetic conductive metal, is that fulcrum rotates with the lower end.
3, button trip gear according to claim 1, it is characterized in that: locking bolt and movable core fuse.
4, button trip gear according to claim 1 is characterized in that: described resetting means is on by button press bar spring location to be set, and back-moving spring one end heads on by the location of the spring on the button press bar, and the other end withstands on the drain pan.
5, according to claim 1 or 4 described button trip gears, it is characterized in that: described back-moving spring is installed in by the button press bar next door.
