The Chinese patent that for example application number is 201420873264.3 discloses a kind of control and protective switching device, comprise housing, be arranged on contact system and electromagnetic system in housing, it is by being provided with arc extinguishing supporting seat at movable contact block place, arc striking piece, arc-extinguish chamber, and on arc extinguishing supporting seat, be provided with striking groove, when the moving contact of this control and protective switching device and static contact are being connected or disconnecting while producing electric arc, electric arc is introduced in arc-extinguish chamber, but mainly for be the electric arc of horizontal direction, also have on vertical direction except horizontal direction and produce electric arc, these electric arcs may be delivered in electromagnetic system, cause bad consequence, therefore be further improved.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of a kind of control and protective switch of striking better effects if.
For achieving the above object; the utility model provides following technical scheme: a kind of control and protective switch; comprise housing, be arranged on contact system and electromagnetic system in housing; between described contact system and electromagnetic system, be provided with dividing plate; described contact system comprises moving contact and static contact; between described dividing plate and static contact, be provided with arc striking piece, conflict place of the corresponding moving contact in described arc striking piece position and static contact, the height of described arc striking piece is greater than the height of static contact.
The utility model further arranges: described arc striking piece one side offers breach and forms inserted sheet in this side, and described housing is provided with the slot coordinating with inserted sheet.
The utility model further arranges: described arc striking piece is provided with corresponding breach equally away from a side of slot.
The utility model further arranges: described static contact is U-shaped structure, and its one end is provided with perpendicular weld part, and the other end extends for the extension of striking, described extension be provided with for the joint end of housing clamping.
The utility model further arranges: described extension reduces to other end width gradually from static contact one end, and described extension and joint end form the recess passing through for electric arc.
Compared with prior art; the utility model has the advantage of: by be provided with arc striking piece between dividing plate and static contact; and the height of arc striking piece is higher than the height of static contact; therefore while running into the electric arc that produces vertical direction; arc striking piece can play and stop and the effect of striking; avoiding this electric arc to be delivered to electromagnetic system affects situation appearance that it is normally worked, and makes striking effect more comprehensively with remarkable, and guarantee control and protective switch can be worked for a long time normally.

Detailed description of the invention
Referring to figs. 1 through Fig. 3, the utility model embodiment is described further.
A kind of control and protective switch; comprise housing 1, be arranged on contact system 2 and electromagnetic system 3 in housing 1; between contact system 2 and electromagnetic system 3, be provided with dividing plate 4; contact system 2 comprises moving contact 5 and static contact 6; between dividing plate 4 and static contact 6, be provided with arc striking piece 7; conflict place of the corresponding moving contact 5 in arc striking piece 7 positions and static contact 6, the height of arc striking piece 7 is greater than the height of static contact 6.
Static contact 6 is U-shaped structure, and its one end is provided with perpendicular weld part 8, and the other end extends for the extension 14 of striking, extension 14 be provided with for the joint end 9 of housing 1 clamping.
And extension 14 reduces to other end width gradually from static contact 6 one end, extension 14 forms with joint end 9 recess 13 passing through for electric arc;
By be provided with arc striking piece 7 between dividing plate 4 and static contact 6, and the height of arc striking piece 7 is higher than the height of static contact 6, therefore while running into the electric arc that produces vertical direction, arc striking piece 7 can play and stop and the effect of striking, avoid this electric arc to be delivered to electromagnetic system 3 and affect the situation appearance of its normal work, electric arc on arc striking piece 7 can be derived and finally be knocked out by arc-extinguish chamber by recess 13, make striking effect more comprehensively with remarkable, guarantee control and protective switch can be worked for a long time normally, normally on housing 1 diapire, block is set simultaneously, block and housing 1 sidewall form buckling groove, and then joint end 9 can be connected to buckling groove, can avoid like this contact body to affect the installation of arc-extinguish chamber, static contact 6 middle part width are narrower, the more flexible distortion of contact body, be easier to clamping operation, U-shaped structure can be arranged on housing 1 in more stable grafting, and be provided with perpendicular weld part 8 in one end of contact body, like this can be better by the copper wire welding being connected with electromagnetic system 3 on weld part 8, and the contact area of this and copper cash by weld part 8 is larger, welding is more stable and firm, the joint end 9 of static contact 6 can avoid static contact 6 to affect the installation of arc-extinguish chamber with the clamping of buckling groove, the be more convenient for installation of arc-extinguish chamber.
Wherein arc striking piece 7 one sides offer breach 10 and form inserted sheet 11 in this side, housing 1 is provided with the slot 12 coordinating with inserted sheet 11, by inserting mode, arc striking piece 7 is arranged on housing 1, preferably arc striking piece 7 is provided with corresponding breach 10 equally away from a side of slot 12 simultaneously, arrange so when mounted and just just toss about without distinguishing, at will which side all can with housing 1 installation of pegging graft, operation is more convenient and facilitates.
The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection domain of the present utility model. It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
