Abstract
The utility model relates to a structure of a breaker and belongs to electricity. The breaker consists of a switch main body and a conducting strip accommodated in the switch main body. Mainly an integrated embedded groove is formed at one end of the conducting strip. The embedded groove is provided with an embedded hole. The conducting strip is fixed on a terminal strip by the embedded hole. By the embedded groove, the width of the end of the conducting strip at the position of the embedded groove is slightly less than the width of the other end of the conducting strip so that the conducting strip has elasticity to generate the characteristic of generating forward and reverse bounce deformation. The end of the conducting strip, which is far away from the embedded groove, is provided with a hole for assisting the conducting strip in carrying out reciprocating movement, so that the conducting strip does not need to be subjected to redundant cutting processing in the production process by the embedded groove. The breaker has the characteristic of cost and process saving.

As the patent No. is 090209910, name is called the Taiwan patent of [a kind of conducting strip structure improvement of switch], the technology that it disclosed is: Yu Zuli end central authorities cutting one appropriate gap, utilize the condensation group upright, make the gap closing, form the outer end broad and organize the narrower shape of upright end, be assembled on the lug plate, make it form similar dish-like balanced forward or backwards crooked radian, characteristic with two-way moment bouncing distortion electrically connects the state that electricity presents downward contact or upwards kicks up on the contact flat spring in the middle of making.
Above-mentioned yet " a kind of conducting strip structure improvement of switch " still exists following point to wait to improve when using:
1, fraction defective is high.
2, promptly can concern the bounce time of its contact flat spring by this gap, then can be related to good rate, have the risk of high fraction defective in the angle of pullling.
3, its group is upright holds in the both sides, cut place and must hole respectively, makes it be able to carry out riveted with conductive component.
The utility model content
The purpose of this utility model is to provide a kind of structure of circuit breaker, solves the problem that existing circuit breaker contact flat spring has high fraction defective risk.
A kind of structure of circuit breaker; described circuit breaker comprises a Switch main body; contain a conducting strip that power-off protection is provided in this Switch main body; this conducting strip one end forms integrated caulking groove; make this conducting strip be slightly less than the width of the conducting strip other end in the width of this caulking groove end by this caulking groove; make this conducting strip have elasticity, and this conducting strip is used for the hole that auxiliary this conducting strip carries out reciprocal activity in be provided with one away from this caulking groove end.
Wherein this caulking groove is provided with an embedding hole for the build-in fixture;
Wherein this caulking groove is fixed on the lug plate by this fixture;
Wherein this conducting strip is positive and negative or reverse balanced crooked radian, has the characteristic of two-way moment bouncing distortion;
Wherein this conducting strip is in be provided with a contact flat spring to this caulking groove end extension away from this caulking groove end place;
Wherein this contact flat spring is provided with one for the perforation that electrical contact is set;
Wherein a pull bar further spurs and is used for the hole that the additional conductive sheet carries out reciprocal activity.
Advantage of the present utility model is:
1, fraction defective also effectively reduces.
2, hold together to close again after need not to use traditional prior art to cut, make its conducting strip produce the bending distortion and have elasticity.
3, conducting strip of the present utility model is formed in one, and beats recessedly forming a caulking groove in an end, and burrows on this caulking groove to form an embedding hole, has exempted above-mentioned existing technology.
4, the utility model is had by above-mentioned technology for having exempted the operation of cutting, has promptly saved manufacturing time, and saves the necessary cost of cutting, and only needs an embedding hole to be connected with electrical contact, reaches the progressive of saving operation and cost equally.
5, by the combining of this hole and pull bar, make this conducting strip change curved shape.

Embodiment
As accompanying drawing 1 to shown in the accompanying drawing 3; stereogram for the utility model conducting strip; the floor map of preferred embodiment and enforcement schematic diagram; find out that by knowing among the figure the utility model comprises a Switch main body 10; accommodating one in this Switch main body 10 provides power-off protection and is the bent radian of positive and negative or reverse equilibrium; conducting strip 20 with characteristic of two-way moment bouncing distortion; these conducting strip 20 1 ends form integrated caulking groove 21; this conducting strip 20 is slightly less than the width of conducting strip 20 other ends in the width of these caulking groove 21 ends; make this conducting strip 20 have elasticity; and this conducting strip 20 is in be provided with a contact flat spring 22 to this caulking groove 21 ends extension away from these caulking groove 21 ends; this contact flat spring 22 is provided with one for the perforation 221 that electrical contact 30 is set; wherein this caulking groove 21 is provided with an embedding hole 211 for build-in fixture 40; this caulking groove 21 is fixed on the lug plate 50 by this fixture 40; this conducting strip 20 is used for the hole 23 that auxiliary this conducting strip 20 carries out reciprocal activity in be provided with one away from these caulking groove 21 ends in addition, and this hole 23 is further by a pull bar 60 pullings.
By above-mentioned structure, form design, be described as follows with regard to use situation of the present utility model, as accompanying drawing 2 to shown in the accompanying drawing 5, floor map for the utility model preferred embodiment, implement schematic diagram, the crooked illustrative view of action schematic diagram and conducting strip, find out by knowing among the figure, this pull bar 60 is connected with this hole 23, and when this pull bar 60 supports passing with this hole 23 toward a direction, by last, lower support bar 70,71 support this conducting strip 20 as the strong point, make this conducting strip 20 produce a brake arm, form a rightabout bouncing distortion, and the contact flat spring 22 in the middle of making simultaneously bounces toward the rightabout of conducting strip 20 spring directions freely, moreover, if these conducting strip 20 distortion are bent into
During shape, 22 of this contact flat springs surpass this conducting strip 20, and also by this electrical contact 30 and these electrical contact 31 mutual conflict conductings, make it form the ON state, if this pull bar 60 when this conducting strip 20 is down passed, makes these conducting strip 20 conflict lower support bars 71 this conducting strip 20 being produced forms
Therefore shape makes simultaneously that spring surpasses horizontal line to this contact flat spring 22 because of braking force produces upwards, and this electrical contact 30 separates with this electrical contact 31, to form the OFF state, wherein, when producing high temperature when current overload, these conducting strip 20 automatic bouncing distortions is become
Shape is cut off the electricity supply to protect it, if when these conducting strip 20 temperature have been reduced to the predetermined elasticity temperature, then bounces back
Shape, in addition, this conducting strip 20 can determine whether by different materials in the spring answer automatically of cooling back.Moreover, this conducting strip 20 is connected with this lug plate 50 by this fixture 40 by this caulking groove 21, different with employed must the cutting of prior art respectively at both sides boring, and its operation that can reach, cost lower all relatively, but must can reach identical effect.
