Abstract
The utility model relates to an alternating current contactor with a dustproof cover. The alternating current contactor comprises a casing, an electromagnetic mechanism, a transmission mechanism, a contact point system and an arc extinguishing system are mounted in the casing, the casing comprises a lower casing and a cover plate, the cover plate is disposed on the lower casing and equipped with the dustproof cover, two sides above the cover plate are respectively equipped with a standby expansion boss, and the cross section of each expansion boss is swallow-tailed. The alternating current contactor is characterized in that the dustproof cover is clamped and engaged with the expansion bosses of the cover plate fixedly. The alternating current contactor has the advantages that the bottom of the dustproof cover is equipped with fastener pins, the dustproof cover is fixedly clamped and engaged with the expansion bosses of the cover plate via the fastener pins, and then by aid of the method, fixing connection of the dustproof cover and the cover plate can be realized without screw nails, thereby not only bringing convenience for assembly and disassembly of the dustproof cover and maintenance, increasing assembly efficiency, and being capable of saving relative cost simultaneously.
Description
Technical field
The utility model relates to a kind of electric elements, relates to a kind of A.C. contactor with dust cover in particular, belongs to the low-voltage electrical apparatus field.
Background technology
At present, Chinese patent discloses a kind of novel dustproof contactor (ZL200720072530.2), this patent includes electromagnetic mechanism, transmission mechanism, contact system, arc quenching system and housing, described housing includes lower house and cover plate, described electromagnetic mechanism, transmission mechanism, contact system and arc quenching system are installed in the lower house, described cover plate lid is put on lower house, for having prevented that pollutants such as dust from entering in the lower house, electronic devices and components in the corrosion lower house, influence the useful life of A.C. contactor, be provided with a dust cover on described cover plate, this dust cover is fixedlyed connected with cover plate by screw; Adopt this mode, can effectively prevent pollutant corrosion electronic devices and components such as dust, improve the useful life of electronic devices and components; But because dust cover adopts the screw mode fixing on the cover board, its structure is not only complicated like this, and working efficiency is low excessively when adopting its assembly and disassembly of screw, is unfavorable for production and assembly and dismounting maintenance.
Summary of the invention
Technical problems such as working efficiency is lower when adopting screw to be unfavorable for that assembly and disassembly maintenance and production and assembly are keeped in repair with dismounting in order to solve dust cover; The utility model provides a kind of A.C. contactor with dust cover, and it is simple in structure, and cost is lower, and can effectively improve the dust cover assembly and disassembly working efficiency in when maintenance.
For solving above technical problem, the technical scheme that the utility model is taked is a kind of A.C. contactor with dust cover, it includes housing, in the described housing electromagnetic mechanism is installed, transmission mechanism, contact system, arc quenching system, described housing includes lower house and cover plate, described electromagnetic mechanism, transmission mechanism, contact system and arc quenching system are installed in the lower house, described cover plate lid is put on lower house, one dust cover is installed on the described cover plate, on the cover board square both sides respectively are provided with a standby expansion boss, and this cross section of expanding boss becomes dovetail shaped; It is characterized in that described dust cover connects and fixes with the expansion boss of cover plate cooperates.
Further, described dust cover two bottom sides is equipped with card base, and this card base front end is provided with one and is circular-arc barb boss, and this barb boss snaps in cover plate and expands in the dovetail groove of boss.
The beneficial effects of the utility model are in the dust cover bottom card base to be set, utilizing card base and cover plate expansion boss to connect and fix cooperates, adopt this mode, can not need screw just can realize fixedlying connected of dust cover and cover plate, the so not only assembly and disassembly of convenient dust-proofing cover, improve the assembling benefit and be convenient to maintenance, simultaneously, also can save corresponding cost.

Specific embodiments
Below in conjunction with accompanying drawing the utility model execution mode is described further:
As shown in Figures 1 to 4, a kind of A.C. contactor of the utility model with dust cover, it includes housing 1, in the described housing 1 electromagnetic mechanism is installed, transmission mechanism, contact system, arc quenching system, described housing 1 includes lower house 11 and cover plate 12, described electromagnetic mechanism, transmission mechanism, contact system and arc quenching system are installed in the lower house 11, described cover plate 12 lids are put on lower house 11, one dust cover 2 is installed on the described cover plate 12, both sides respectively are provided with a standby expansion boss 121 above cover plate 12, and this cross section of expanding boss 121 becomes dovetail shaped; Technical problems such as working efficiency is lower when adopting screw to be unfavorable for assembling and production and assembly in order to solve dust cover 2, described dust cover 2 connects and fixes with the expansion boss 121 of cover plate 12 and cooperates; Adopt this mode, can not need screw just can realize fixedlying connected of dust cover 2 and cover plate 12, the so not only assembly and disassembly of convenient dust-proofing cover 2 improve the assembling benefit and are convenient to maintenance, simultaneously, also can save corresponding cost.
In the present embodiment, assembling and dismounting maintenance for convenient dust-proofing cover 2, working efficiency when improving assembling and dismounting maintenance, described dust cover 2 two bottom sides are equipped with card base 21, these card base 21 front ends are provided with one and are circular-arc barb boss 211, this barb boss 211 snaps in the dovetail groove of expansion boss 121 of cover plate 12, because card base 21 front ends are provided with circular-arc barb boss 211, only need when mounted firmly to push downwards, just card base 21 can be snapped in cover plate and expand in the dovetail groove of boss 121, can greatly improve the assembling benefit of dust cover 2 like this; In when dismounting, the same dust cover 2 of only need firmly buckling just can separate in card base 21 and the dovetail groove of expanding boss 121, adopts this structure, not only can effectively improve working efficiency, simultaneously, also can save the fixedly screw of usefulness, the production cost of reduction integral body; Certainly, also can not adopt card base 21 structures, such as be provided with in dust cover 2 bottoms one with expand the draw-in groove that boss 121 dovetail grooves are complementary, can reach identical purpose equally, but since with expand the draw-in groove mode that boss 121 dovetail grooves are complementary, its structure relative complex, and be unfavorable for production and processing, therefore, the execution mode of present embodiment is preferential execution mode.
The foregoing description should not be considered as restriction of the present utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection range of the present utility model.
