Description
Technical field
The utility model is related to miniature circuit breakers, and in particular to a kind of miniature circuit breaker transmission mechanism.
Background technology
Miniature circuit breaker is mainly used for the overload of public building, the illumination of house and similar building, distribution line and equipment
And short-circuit protection.Transmission mechanism is designed in miniature circuit breaker, transmission mechanism is used to receive the power of handle action, and drives dynamic touch
Head action, realizes the combined floodgate and separating brake of moving contact and static contact, and conventional drives generally require to lead to since structure is more complicated
It crosses and wears copper pipe and link together by copper pipe both ends riveting, and then by several parts, its abjection is placed, later again by copper pipe
It is set in shaft, had not only increased number of components in this way but also increases riveting process so that production and assembling are all cumbersome, separately
Outside, the stability acted when being driven is also poor.
Invention content
In view of the deficiency of background technology, the technical problem to be solved by the utility model is to provide a kind of structure is simpler
It is single, it produces, assemble miniature circuit breaker transmission mechanism that is more convenient, while improving its action stability.
For this purpose, the utility model is realized using following scheme：
Miniature circuit breaker transmission mechanism, it is characterised in that：Including lock, tripping, contact base and moving contact, the lock
Middle part is rotatablely connected by shaft and contact base, and the first torsional spring is arranged with outside the axle sleeve passed through on the lock for shaft, described
The outside of first one end and lock clamping, outside and the contact base clamping of the other end, described tripping one end and contact base
Upper right side is rotatablely connected, and the other end is clamped with lock, the rear side of the contact base integrally provided with pillar, the moving contact it is upper
Portion is rotatably sleeved on pillar, and the second torsional spring, the outside clamping of second one end are also arranged on the pillar
On contact base, the other end is equipped with bending part, and the bending part is connected to the right-hand end of moving contact, and its outside and moving contact pressure
Tightly, the left-hand end of the moving contact is resisted by block integrally formed on contact base, and the bottom of the contact base is equipped with bar hole.
Using above-mentioned technical proposal, the advantages of the utility model, is：1st, directly connected between lock and contact base by shaft
It connects, is effectively simplified connection structure；By the way that the first torsional spring is set to improve the stability acted between lock and contact base, protect simultaneously
Card lock and contact base will not be deviate from from shaft；2nd, by setting the second torsional spring, when moving contact is contacted with static contact in combined floodgate shape
During state, the second torsional spring provides pretightning force between moving contact and contact base so that moving contact can press static contact, ensure to close a floodgate
When stability.
For the ease of assembling, positioning, preferably, the side of the moving contact is equipped with the clamping clamped for the second torsional spring
Slot.
For the ease of assembling, positioning, preferably, the lock is equipped with the first clamping portion, the contact base is equipped with
Second clamping portion, the outside of first one end are clamped with the first clamping portion, the outside of first one end and the
Two clamping portions are clamped.
Description of the drawings
The utility model has drawings described below：
Fig. 1 is the shape assumption diagram of the utility model；
Fig. 2 is the view at Fig. 1 back sides.
Specific embodiment
As shown in the figure, miniature circuit breaker transmission mechanism disclosed in the utility model, including lock 1, tripping 13, contact base 10
With moving contact 8, the middle part of 1 right end of lock is rotatablely connected, and rotatably set centered on shaft 3 by shaft 3 and contact base 10
It puts, the first torsional spring 4 is arranged with outside the axle sleeve 2 passed through on lock 1 for shaft 3, the outside of the first one end 6 is with latching on 1
First clamping portion 5 is clamped, and the outside of the first torsional spring other end 12 is clamped with the second clamping portion 11 on contact base 10, tripping 13 1
End and the upper right side of contact base 10 are rotatablely connected, and the other end and 1 clamping of lock, the rear side of contact base 10 is integrally provided with pillar
15, the top of moving contact 8 is rotatably sleeved on pillar 15, and the second torsional spring 16, the second torsional spring one are also arranged on pillar 15
End 14 is connected on contact base 10, and its outside is compressed with contact base 10, and the second torsional spring other end 17 is equipped with bending part 9, bending
Portion 9 is connected in the card holding trough 18 of 8 right-hand end of moving contact, and its outside is compressed with card holding trough 18, and the left-hand end of moving contact 8 is by touching
Integrally formed block 19 resists on headstock 10, and the bottom of contact base 10 is equipped with bar hole 7.
The operation principle of the utility model is：During combined floodgate, handle mechanism drives tripping 13 to act to the right, tripping 13 while band
Dynamic lock 1 and contact base 10 are rotated clockwise along shaft 3, by the way that the first torsional spring 4 is set to provide buffering, both so that 1 He of lock
Opposite collide, and so that the rotation of the two is more smooth, later, when 8 bottom end of moving contact will not occur in rotation for contact base 10
Contact part when contacting and compress with static contact, static contact can be supplied to 8 one active forces to the right of moving contact, second turn round at this time
Spring 16 can stress and compress, while be supplied to 8 one reaction forces to the left of moving contact so that the contact part of moving contact 8 with it is quiet
The compression of contact, so as to ensure stability during breaker closing.
