Description
Technical field
The utility model relates to a kind of A.C. contactor, especially a kind of A.C. contactor with auxiliary switch assembly and auxiliary switch assembly thereof.
Background technology
A.C. contactor is widely used in the closed and disconnected of power equipment, and A.C. contactor has two groups of auxiliary contacts conventionally, a pair ofly often opens, a pair of normally closed, in order to form logical circuit, use, and as self-hold circuit, XOR gate (interlocking) circuit, priority circuit etc.Current auxiliary contact are generally outside the main casing of independently installing with the form of auxiliary switch assembly, auxiliary switch assembly mainly comprises auxiliary shell, moving contact, often opens fixed contact, normally closed fixed contact, on moving contact, be connected with the lever through auxiliary shell, moving contact is connected by the contact support of lever and A.C. contactor main body, during the contact Supporting connectivity of lever and A.C. contactor main body, need in body shell, offer an assembled confession lever and pass, and on the housing of existing A.C. contactor, all not arrange assembled mouthful.
Summary of the invention
For above-mentioned reasons, it is a kind of simple in structure that the purpose of this utility model is to provide, and easily assembling, assembles firm A.C. contactor and auxiliary switch assembly thereof.
For achieving the above object, the utility model adopts a kind of A.C. contactor, the center, a side of the shell of A.C. contactor is provided with assembled mouthful for being connected with auxiliary switch assembly, assembled mouthful of upper end forms intilted inclined-plane, assembled mouthful is outside equipped with cover plate, and cover plate is connected with side is quick detachable, between cover plate and the upper end of assembled mouthful, vacates a dismounting mouthful, the side bottom of described shell is provided with a bayonet socket and a fixture block, and the both sides, side of described shell are provided with draw-in groove.
On assembled mouthful on above-mentioned A.C. contactor, be stamped cover plate, when unassembled auxiliary switch assembly, can prevent that foreign matter from falling into, between cover plate and shell, adopt easy to assemble connection thinner or that tie point is less, and on the cover board side arranges dismounting mouthful, conveniently with article such as screwdrivers, directly injecting dismounting mouthful outwards pries open cover plate, be easy to the assembling of auxiliary switch assembly, and the inclined-plane that arranges, assembled mouthful top can not only guarantee that cover plate can not fall into A.C. contactor inside, can also prevent for prying open that the article such as screwdriver of cover plate touch the inside of A.C. contactor and the performance that has influence on A.C. contactor.
The utility model also comprises the auxiliary switch assembly being arranged on above-mentioned A.C. contactor, the assembled mouthful of corresponding center that is arranged on of the lever of auxiliary switch assembly and A.C. contactor, bayonet socket on the corresponding A.C. contactor in bottom of auxiliary switch assembly forms T-shaped grab, fixture block on corresponding A.C. contactor forms L-type grab, and the draw-in groove on the corresponding A.C. contactor in both sides of auxiliary switch assembly forms Elastic buckle.
Auxiliary switch assembly and above-mentioned A.C. contactor are suitable, and the grab of below and the buckle of side not only make stable connection, and for convenience detach.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of A.C. contactor of the present utility model.
Fig. 2 is the schematic diagram of auxiliary switch assembly of the present utility model.
Embodiment
Embodiment of the present utility model is a kind of A.C. contactor and auxiliary switch thereof, as shown in Figure 1, the center, a side of the shell 1 of A.C. contactor is provided with assembled mouthful 11 that is connected with auxiliary switch assembly 2, assembled mouthful of 11 upper ends form intilted inclined-plane 12, be outside equipped with cover plate 13 for assembled mouthful 11, adopt quick detachable connection thinner and that tie point is less being connected between cover plate 13 and shell 1, between cover plate 13 and the upper end of assembled mouthful 11, vacate a dismounting mouth 14, the side bottom of this shell 1 is provided with a bayonet socket 15 and a fixture block 16, the both sides, side of this shell 1 are provided with draw-in groove 17.
