Description
Technical field
The utility model relates to a kind of contactor, refers in particular to a kind of main noddle on contactor automatic compensation structure.
Background technology
Contactor is generally side direction and installs when installing, due to Action of Gravity Field, dynamic tactile bridge contact center line cannot be entirely on the center with quiet contact plate contact center line, and especially for big current contactor, because its armature heavier-weight, both inconsistent phenomenons are more serious.When this just causes contactor to work, electrical endurance is lower.And at present, adopt 2 conventional above-mentioned weak points of mode, scheme 1 to be thicken silver point and solve dynamic/static contact by strengthening and misplace the electrical endurance reduction problem caused.The weak point of the program is to improve product cost.And scheme 2 increases thickness by side bottom contact, make up the inconsistent phenomenon that gravity factor causes.Must install thickening side down when weak point is that contactor is installed, installing if contactor is inverted by mistake, then cannot head it off.
Utility model content
In order to overcome shortcoming and the weak point of background technology, solving existing dynamic tactile bridge contact center line cannot be entirely on the center with quiet contact plate contact center line, causes both to occur inconsistent phenomenon, thus the problem that when causing contactor to work, electrical endurance reduces.
The technical solution of the utility model is: a kind of main noddle on contactor automatic compensation structure, comprise pedestal, dynamic tactile bridge bracket, dynamic tactile bridge, static contact panel, the described dynamic bridge that touches is provided with moving contact, described static contact panel is provided with fixed contact, described static contact panel is installed on pedestal, the described dynamic bridge that touches is installed on dynamic tactile bridge bracket, described pedestal is provided with groove, the described dynamic bridge bracket that touches is positioned at groove, there is gap in described dynamic touching between the side of bridge bracket and groove inner wall, described dynamic two sides of touching bridge bracket are provided with installing hole, spring and steel ball is provided with in described installing hole, the inner of described spring and the bottom connection of installing hole touch, described steel ball is located at the outer end of spring and is contacted on the groove inner wall of pedestal.
The described dynamic installing hole touching each side of bridge bracket is 2, and described 2 installing holes are separated by a distance and be positioned in same level.
Described dynamic side of touching bridge bracket is provided with arc boss, and described installing hole is located on arc boss, and the inwall of the groove of described pedestal is provided with outwardly and corresponding with described arc boss square boss, and described steel ball contacts in described square boss.
the utility model has following beneficial effect:mounting spring is used at the dynamic each forming hole in bridge bracket both sides that touches because this contactor adopts, steel ball be placed on spring with base into contact, the dynamic bridge bracket that touches, under the effect of upper and lower two springs, remains on centre position, thus the dislocation avoided between dynamic/static contact, and effectively can reduce pedestal wearing and tearing.Install even if be inverted by contactor by mistake, also automatically regulated by spring, moving contact still mediates.

In figure, pedestal 1, dynamic tactile bridge bracket 2, dynamic tactile bridge 3, static contact panel 4, moving contact 5, fixed contact 6, groove 7, installing hole 8, spring 9, steel ball 10, arc boss 11, square boss 12.
Embodiment
Be described further for embodiment of the present utility model below:
As shown in the figure, a kind of main noddle on contactor automatic compensation structure, comprise pedestal 1, dynamic tactile bridge bracket 2, dynamic tactile bridge 3, static contact panel 4, the described dynamic bridge 3 that touches is provided with moving contact 5, described static contact panel 4 is provided with fixed contact 6, described static contact panel 4 is installed on pedestal 1, the described dynamic bridge 3 that touches is installed on dynamic tactile bridge bracket 2, described pedestal 1 is provided with groove 7, the described dynamic bridge bracket 2 that touches is positioned at groove 7, there is gap in described dynamic touching between the side of bridge bracket 2 and groove 7 inwall, described dynamic two sides of touching bridge bracket 2 are provided with installing hole 8, spring 9 and steel ball 10 is provided with in described installing hole 8, the inner of described spring 9 and the bottom connection of installing hole 8 touch, described steel ball 10 is located at the outer end of spring 9 and is contacted on groove 7 inwall of pedestal 1.Installing hole has certain degree of depth, spring is contained in hole, and steel ball is compressed on spring, the elastic force produced by spring withstands on the inwall of groove, the dynamic bridge bracket 2 that touches can regulate automatically according to the spring force of both sides, and dynamic touch bridge bracket 2 move drive moving contact 5 to contact with fixed contact 6 time, dynamicly touch the steel ball outside bridge bracket 2 along the inwall of groove and rolls, can not wear and tear pedestal and move tactile bridge bracket.Therefore, according to such scheme, mounting spring is used at the dynamic each forming hole in bridge bracket both sides that touches because this contactor adopts, steel ball be placed on spring with base into contact, the dynamic bridge bracket that touches is under the effect of upper and lower two springs, remain on centre position, thus avoid the dislocation between dynamic/static contact, and effectively can reduce pedestal wearing and tearing.Install even if be inverted by contactor by mistake, also automatically regulated by spring, moving contact still mediates.
In the utility model, the described dynamic installing hole 8 touching each side of bridge bracket 2 is 2, and described 2 installing holes 8 are separated by a distance and be positioned in same level.All arrange the corresponding installing hole of 2 Widths in two sides of support, arrange spring and steel ball in hole, 2 installing holes of each side are separated by a distance and in same level, such that dynamic to touch bridge bracket 2 stationarity better.Touch bridge bracket lightweight packages if dynamic overweight, affect stability, by the corresponding spring of increase and steel ball quantity, can ensure that dynamic bridge bracket all-the-time stable of touching is in centre position (as shown in Figure 4).
In the utility model, described dynamic side of touching bridge bracket 2 is provided with arc boss 11, described installing hole 8 is located on arc boss 11, the inwall of the groove 7 of described pedestal 1 is provided with outwardly and corresponding with described arc boss 11 square boss 12, and described steel ball 10 contacts in described square boss 12.Adopt arc boss 11 and square boss 12 to coordinate with the rolling realizing steel ball, effectively reduce contact area, and guidance quality is better, improves the dynamic stability touching bridge bracket movement.
Embodiment should not be considered as the restriction to utility model, but any improvement done based on spirit of the present utility model, all should within protection range of the present utility model.
