Description
Technical field
The utility model belongs to circuit protection structure technical field, and in particular to a kind of compressor overload protector.
Background technology
Compressor circuit is in series with overload protective device in loop, when loop current is excessive or compressor temperature is too high,
Overload protective device can disconnect and disconnect power circuit, reach the purpose of protection compressor and electrical equipment.
Existing compressor protector structure is all that the heating wire extended spirally is set in protector outer casing, heating wire string
It is connected in circuit loop, bimetal leaf is set above heating wire, movable contact spring component is set above bimetal leaf, movable contact spring component
Moving contact keeps contacting with the static contact of circuit loop.When loop works electric current is excessive or compressor temperature is too high, overload
Bimetal leaf in protector can produce deformation because of thermal deformation, and the bimetal leaf after deformation can promote movable contact spring component, make it
On moving contact separated with loop static contact so that power circuit disconnect.
Bimetal leaf will not access power circuit, also not fixed mutually with any part, but be freely positioned over movable contact spring
Within space between component and heating wire, it can freely overturn when energized, but in current anomaly, heating wire is by big electricity
During stream impact, that bimetal leaf is upspring be present and touch movable contact spring component, seriously may be with movable contact spring component touch adhesion
Loop is formed, causes protector to fail.
Utility model content
The purpose of this utility model is to provide a kind of compressor overload protector solve existing overload of compressor and protect
The problem of easily causing protector to fail with movable contact spring component adhesion during bimetal leaf upset existing for shield device.
Technical scheme is used by the utility model：A kind of compressor overload protector, including base and cover plate are formed
Protector cavity, the cavity inner bottom part is provided with connected heater and static contact component, set above the heater
There is bimetal leaf, the bimetal leaf is connected with push rod, movable contact spring component, the movable contact spring component are provided with above the push rod
Moving contact be in contact with loop static contact, the bimetal leaf drives push rod to promote the movable contact spring component to move after being thermally deformed
It is dynamic that moving contact is separated with static contact.
The characteristics of the utility model, also resides in,
Limit assembly is further fixed between bimetal leaf and the movable contact spring component, the push rod passes through described spacing group
Part.
The limit assembly is potsherd.
The cover plate lower surface is provided with depression bar and is used to fix the limit assembly.
The heater is fever tablet.
A kind of compressor overload protector of the present utility model solves double existing for existing compressor overload protector
The problem of sheet metal easily causes protector to fail when overturning with movable contact spring component adhesion.It uses fever tablet to substitute heating wire,
The resistance to rush of current ability of heater element is improved, by product structure optimization, makes interiors of products space compacter；Bimetal leaf with
Between movable contact spring component, post rod mechanism is introduced, centre is spacing provided with ceramics, bimetal leaf and movable contact spring component is separated, effectively
Prevent short circuit problem；Increase the depression bar of fixed limit assembly on cover plate, ensure that the position of limit assembly is fixed, prevent push rod
Action failure.
Brief description of the drawings
Fig. 1 is a kind of structural representation of compressor overload protector of the utility model；
Fig. 2 is a kind of Structure explosion diagram of compressor overload protector of the utility model.
In figure, 1. bases, 2. cover plates, 3. heaters, 4. static contact components, 5. bimetal leafs, 6. limit assemblies, 7. tops
Bar, 8. movable contact spring components, 9. depression bars, 10. pins.
Embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of structure of compressor overload protector provided by the utility model as depicted in figs. 1 and 2, including the He of base 1
The protector cavity that cover plate 2 is formed, base 1 and cover plate 2 can be attached assembling using rivet hot melten gel, and the upper surface of cover plate 2 is set
Pin 10 is put, the heater 3 and static contact component 4 that cavity inner bottom part is fixedly linked, heater 3 and static contact component 4 form electricity
Road loop, cavity is interior to be provided with a groove position setting bimetal leaf 5 positioned at the top of heater 3, and insulation is connected with bimetal leaf 5
Push rod 7, the top of push rod 7 sets movable contact spring component 8, and the moving contact of movable contact spring component 8 is in contact with loop static contact component, when
Loop current is excessive or when compressor temperature is too high, and bimetal leaf 5 withstands push rod 7 and moved upwards after being thermally deformed, and push rod 7 touches
Dynamic movable contact spring component 8 moves towards the direction away from static contact component 4 causes moving contact to be separated with static contact component 4.Insulating knockout pin 7
Setting so that bimetal leaf 5 and movable contact spring component 8 will not stick together phenomenon.
Preferably, heater 3 selects fever tablet, and fever tablet can increase heavy current impact capacity, but also can contract
Small protector volume, realize overload protective device volume Miniaturization Design.
Preferably, be additionally provided with cavity a groove position be used for place insulation limit assembly 6, limit assembly 6 is positioned at double golden
Belong between piece 5 and movable contact spring component 8, push rod 7 passes through limit assembly 6.Limit assembly 6 is realized to the spacing of bimetal leaf 5, is made
Its deformation can control within the specific limits, meanwhile, limit assembly 6 can limit the moving direction of push rod 7, avoid push rod 7 dynamic
Fail.Exemplary, limit assembly 6 is potsherd.
Further, the lower surface of cover plate 2 sets depression bar 9, the face limit assembly 6 of depression bar 9 when cover plate 2 assembles with base 1
Position, push down limit assembly 6 and it is fixed, prevent limit assembly 6 to be subjected to displacement, upper and lower play.
When compressor loop electric current is excessive or compressor temperature is too high, the heated hair of bimetal leaf 5 of the present utility model
Raw deformation, the driving motion of push rod 7 start spring assembly 8 until pushing up, and make the moving contact and compressor loop stationary contact of movable contact spring component 8
Head assembly 4 separates, so that power circuit disconnects.The utility model added between bimetal leaf and movable contact spring component push rod and
Potsherd, not only the moving range of bimetal leaf is defined, and also avoid when bimetal leaf is freely overturn may be with
Movable contact spring component phase Adhesion formation loop, the problem of causing protector to fail.
