But, so effective conductive areaLittle, the temperature rise of breaker is difficult to be controlled in effective range.
Therefore,, for above deficiency, the invention provides contact connecting structure under a kind of breakerAnd breaker.
Summary of the invention
(1) technical problem that will solve
The object of this invention is to provide under a kind of breaker contact connecting structure and breaker to solveEffective conductive area temperature rise little and breaker that existing lower contact connected mode exists is difficult to controlThe problem of system.
(2) technical scheme
In order to solve the problems of the technologies described above, one aspect of the present invention provides contact under a kind of breakerSyndeton, it comprises vacuum bubbles, lower static contact, frame plate and fixation kit, vacuum bubbles is installedThe quiet end axle of lower end is through frame plate is installed, and quiet end axle is fixed on installation frame plate by fixation kitUpper, lower static contact comprises the horizontal component and the vertical portion that are connected, the horizontal part of lower static contactDivide and be arranged on the below of vacuum bubbles and fit with the bottom surface of vacuum bubbles, the horizontal part of lower static contactBelow point, be provided with fastening nut.
Wherein, described fixation kit comprises the first nut and the second nut, the first nut and secondNut lay respectively at install frame plate above and below.
Wherein, also comprise contact pressing plate, described contact pressing plate is arranged on installs frame plate and the second spiral shellBetween mother.
The present invention also provides a kind of breaker on the other hand, and it comprises under above-mentioned breaker tactileSyndeton.
(3) beneficial effect
Technique scheme tool of the present invention has the following advantages: under breaker provided by the invention, touchIn syndeton and breaker, the quiet end axle of vacuum bubbles lower end is through frame plate being installed and by solidLocking assembly is fixed on to be installed on frame plate, and the horizontal component of lower static contact is arranged on the below of vacuum bubblesAnd fit with the bottom surface of vacuum bubbles, by fastening nut, the horizontal component of lower static contact is fixedIn the bottom surface of vacuum bubbles, vacuum bubbles and lower static contact have larger conductive area, breaker like thisTemperature rise can be well controlled, effectively improved the performance of breaker.

Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is done further to retouch in detailState. Following examples are used for illustrating the present invention, but are not used for limiting the scope of the invention.
In description of the invention, it will be appreciated that, term " on ", D score, 'fornt', 'back',Orientation or the position relationship of the instruction such as " vertically ", " level ", " top ", " end " " interior ", " outward "For based on orientation shown in the drawings or position relationship, be only the present invention for convenience of description and simplificationDescribe, instead of instruction or the hint device of indication or element must have specific orientation, withSpecific orientation structure and operation, therefore can not be interpreted as limitation of the present invention. In addition art,Language " first ", " second " be only for describing object, and can not be interpreted as instruction or hint relativelyImportance.
In description of the invention, it should be noted that, unless otherwise clearly defined and limited,Term " installation ", " being connected ", " connection " should be interpreted broadly, and for example, can be fixing companiesConnecing, can be also to removably connect, or connects integratedly; Can be mechanical connection, also canIt is electrical connection; Can be to be directly connected, also can indirectly be connected by intermediary, Ke YishiThe connection of two element internals. For the ordinary skill in the art, concrete feelingsCondition is understood above-mentioned term concrete meaning in the present invention.
In addition,, in description of the invention, except as otherwise noted, the implication of " multiple " is twoOr more than two.
As shown in Figure 1, under breaker provided by the invention contact connecting structure comprise vacuum bubbles 1,Lower static contact 2, installation frame plate 3 and fixation kit, the quiet end axle 101 of vacuum bubbles 1 lower end passesFrame plate 3 is installed, and quiet end axle 101 is fixed on frame plate 3, lower static contact is installed by fixation kit2 comprise the horizontal component and the vertical portion that are connected, and the horizontal component of lower static contact 2 is arranged on veryThe below of cavity 1 and fitting with the bottom surface of vacuum bubbles 1, to ensure larger conductive area,The horizontal component below of lower static contact 2 is provided with fastening nut 6, by fastening nut 6 by lower quietThe horizontal component of contact 2 is fixed on the bottom surface of vacuum bubbles 1.
Particularly, described fixation kit comprises the first nut 4 and the second nut 5, the first nuts 4With the second nut 5 lay respectively at install frame plate 3 above and below, fix simply by nutPracticality, tightness is good.
Preferably, also comprise contact pressing plate 7, described contact pressing plate 7 is arranged on installs frame plate 3With second between nut 5, like this can be securely by solid the quiet end axle of vacuum bubbles 1 lower end 101Fix on and install on frame plate 3.
The breaker that the present invention provides on the other hand comprises contact connecting structure under above-mentioned breaker,In such breaker because the horizontal component of lower static contact 2 and the bottom surface of vacuum bubbles 1 fit,Have larger conductive area, the temperature rise of breaker is easy to be controlled in effective range.
Under breaker provided by the invention in contact connecting structure, the quiet end axle of vacuum bubbles 1 lower end101 through frame plate 3 being installed and being fixed on frame plate 3 is installed by the first nut 4 and the second nut 5Upper, the horizontal component of lower static contact 2 is arranged on the below of vacuum bubbles 1 and the end with vacuum bubbles 1Face fits, and by fastening nut 6, the horizontal component of lower static contact 2 is fixed on to vacuum bubbles 1Bottom surface, vacuum bubbles 1 has larger conductive area, the temperature of breaker with lower static contact 2 like thisRise and can be well controlled, effectively improved the performance of breaker; By at installing rackThe quiet end axle that contact pressing plate 7 can make vacuum bubbles 1 lower end is set between plate 3 and the second nut 5101 are firmly fixed on installation frame plate 3.
The above is only the preferred embodiment of the present invention, it should be pointed out that for this technology and leadsThe those of ordinary skill in territory, not departing under the prerequisite of the technology of the present invention principle, all rightMake some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
