Barrier will not be such that fracture end is placed in secondly once the fracture of the first extension arm, the end being broken in this way will be resisted by convex block top
Or the gap between button and through-hole, a possibility that preventing electric shock in special circumstances well；Two, the button position
On one end of the circuit breaker internal and side far from convex block is provided with baffle, which blocks button when button bounces and lead to
Gap between hole, the gap (namely creepage distance) between such button and through-hole not only extend, and channel also has occurred
Change, such safety substantially increases.
The further setting of the present invention is: the boss is cylindrical boss, is arranged with conductive ring on cylindrical boss, institute
It states and is provided with the first arc protection lug below cylindrical boss, it is convex to be provided with the protection of the second arc below the installation pillar
Piece；The first arc protection lug is extended in close installation pillar side horizontal protection lug, and second arc is protected
Lug is protected close to the down-set perpendicular protection lug in second extension arm one end.
By using above scheme, we protect conductive ring or torsional spring position in the case where unexpected situation occurs to become well
Change and influence the entire product of breaker, be in particular in, when cylindrical boss long-time using and aging in the case where be broken,
Conductive ring will not be fallen to circuit board or static contact or moving contact direction in this way, and in addition torsional spring is also such situation, and herein
It is preferred embodiment that one arc, which protects the shape of lug and the second arc protection lug, and other shapes can also actually play one
Fixed effect.In addition horizontal protection lug and perpendicular protection lug can guide the position fallen, relatively safe in this way, actually
It is not provided with also possible.
Of the invention being further arranged so that below the button is provided with card slot, and first extension arm is placed in card slot
In, side corresponding with baffle is provided with thickening layer on the through-hole medial surface of the circuit breaker base or lid, thickening layer side with
The obverse side wall of through-hole maintains an equal level, and the baffle blocks the gap between button and thickening layer when button bounces.
By using above scheme, advanced optimized to the performance of product and safety, in addition thickening layer in this way,
It can cooperate with convex block plays the role of guiding, keeps button movement more stable.
The present invention is described further with reference to the accompanying drawing.
Detailed description of the invention

Fig. 2 is the schematic diagram of reflection of embodiment of the present invention button, torsional spring and conductive ring；
Fig. 3 is the perspective view of torsional spring of the embodiment of the present invention；
Fig. 4 is the perspective view of the button of the embodiment of the present invention.
Specific embodiment
As shown in Fig. 1-Fig. 4, a kind of experimental rig in leakage circuit breakers includes conductive ring 1 or conducting block, button 2
With conductive torsional spring 3, the conduction torsional spring 3 includes torsional spring circle 31, the first extension arm 32 and the second extension arm 33, wherein torsional spring circle
31 are socketed on the installation pillar 311 of circuit breaker base, and the conductive ring 1 or conducting block are fixed at the convex of circuit breaker base
On platform 11, button 2 is arranged on the through-hole of circuit breaker base or lid, and one end is placed in the outside of circuit breaker base or lid, another
End is placed in circuit breaker internal, and first extension arm 32 is located at the lower section of button 2, and button press 2 promotes under the first extension arm 32
It moves with conductive ring 1 or conducting block into conductive contact, these above-mentioned features are also to have in the prior art, described in the present embodiment
In we be just not described in detail, in the present embodiment, the through-hole medial surface and be provided with can close to the side of torsional spring circle 31
The convex block 4 in the gap 21 after preventing the first extension arm 32 to be broken between fracture end merging button 2 and through-hole, the actually convex block 4
Effect there are two, first is the gap extended between button 2 and through-hole, the first extension arm 32 and the button 2 charged in this way
The distance of end face 22 is just protected, secondly once the fracture of the first extension arm 32, the end being broken in this way will be by 4 top of convex block
It resists, fracture end merging or the gap 21 between button 2 and through-hole will not be made, prevented well in special circumstances
A possibility that electric shock；The button 2 is located on one end of circuit breaker internal and the side far from convex block 4 is provided with baffle 5, the gear
Piece 5 blocks the gap 21 between button 2 and through-hole when button 2 bounces, and usual baffle 5 is vertically arranged with button 2, and baffle 5 is not
It only extends the gap 21 between button 2 and through-hole, the change in channel also has occurred, safety substantially increases.
In embodiments of the present invention, the boss 11 is cylindrical boss 11, is arranged with conductive ring on cylindrical boss 11
1, this selection mainly considers that installs facilitates shape, and actually conductive sheet is also possible, 11 lower section of cylindrical boss
It is provided with the first arc protection lug 111, the lower section of the installation pillar 311 is provided with the second arc protection lug 312；It is described
First arc, which protects lug 111 to be extended in close installation 311 side of pillar, horizontal protection lug 112, second arc
Protect lug 312 close to the down-set perpendicular protection lug 313 in 33 one end of the second extension arm.By using above scheme, we are very
Good protects conductive ring 1 or 3 change in location of torsional spring in the case where unexpected situation occurs and influences the entire product of breaker, specific table
Now, when cylindrical boss 11 long-time using and aging in the case where be broken, such conductive ring 1 will not be to circuit board or quiet
Contact or moving contact direction are fallen, and in addition torsional spring 3 is also such situation, herein the first arc protection lug 111 and the second arc
It is preferred embodiment that shape, which protects the shape of lug 312, and other shapes can also actually play a role.In addition horizontal protection
The position that lug 112 and perpendicular protection lug 313 can guide conductive ring 1 and torsional spring 3 to fall, it is relatively safe in this way, it is real
It is not provided on border also possible.
In embodiments of the present invention, card slot 23 is provided with below the button 2, first extension arm 32 is placed in card slot 23
In, side corresponding with baffle 5 is provided with thickening layer 6,6 side of thickening layer on the through-hole medial surface of the circuit breaker base or lid
Maintain an equal level with the obverse side wall of through-hole, the baffle 5 blocks the gap between button 2 and thickening layer 6 when button 2 bounces, and adds
The setting in this way of thick-layer 6 can also cooperate with convex block 4 plays the role of guiding, keeps button movement more stable.
It is disclosed, be one kind of preferred embodiment, all partial alterations or modification and derived from technology of the invention
Thought and be easy to the person of deducing by those skilled in the art, neither take off patent category of the invention.
