Abstract
The invention relates to a contactor with multi-group auxiliary contacts. A contact support extends a bracket with the same width towards the side edge. The bracket is sequentially provided with a first lattice bracket, a second lattice bracket and a third lattice bracket. A first moving contact assembly and a second moving contact assembly are fixedly placed on the bracket. A first static contact assembly and a second static contact assembly are fixedly connected on a base seat, wherein the first static contact assembly and the second static contact assembly respectively correspond to the first moving contact assembly and the second moving contact assembly. Two lattice brackets are selected to be respectively used for placing the first moving contact assemble and the second moving contact assemble, and meanwhile spatial positions of a electromagnetic system and double-breakpoint main contact system are adjusted, and a pair of auxiliary contacts is rationally added in the same auxiliary contact unit; in addition, by adjusting the directions of the contacts of the static contact assemblies and placing positions and the directions of the contacts of the moving contact assemblies, the types of two auxiliary contact units can be flexibly changed, wherein two pairs of normally open contacts or a pair of normally open contact and a pair of normally closed contacts are included, thereby satisfying application requirements of users.

Summary of the invention
The object of the invention is to overcome the defective of prior art, a kind of limited spatial spread auxiliary contact unit and changeable contactor with many group auxiliary contacts of auxiliary contact unit pattern of utilizing is provided.
For achieving the above object, the present invention adopts a kind of like this contactor with many group auxiliary contacts, comprise base and be positioned at the pedestal that is connected with described base on the described base, establish electromagnetic system in the described base, establish the double breaking points main contact system in the described pedestal, have in the described double breaking points main contact system with described electromagnetic system in moving iron core keep the contact support of interlock, described contact support is positioned at the center in described pedestal chamber, the support of a width is extended in described contact support to side, described support arranges the first lattice support by leu, the second lattice support and the 3rd lattice support, fixed installation the first moving contact component and the second moving contact component on the described support, fixed installation first static contact component and second static contact component corresponding with described the first moving contact component and described the second moving contact component difference on the described pedestal.
Especially, at described the first moving contact component of described the first lattice support fixed installation, at described the second moving contact component of described the second lattice support fixed installation, the contact of the contact of described the first moving contact component and described the second moving contact component towards identical.
Especially, at described the first moving contact component of described the first lattice support fixed installation, at described the second moving contact component of described the 3rd lattice support fixed installation, described the first moving contact component towards downwards, the contact of described the second moving contact component towards upwards.
Especially, be provided with step with described the first moving contact component and the corresponding position of described the second moving contact component on the described pedestal, the up and down two-stage of described step is respectively applied to install described the first static contact component and described the second static contact component.
Especially, described pedestal is provided with the terminal cover that adapts with described step.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, by the contact support is extended the support of a width to side, at support the first lattice support, the second lattice support and the 3rd lattice support are set, therefrom select two lattice supports to be respectively applied to install the first moving contact component and the second moving contact component, simultaneously, electromagnetic system and double breaking points main contact system are carried out adjustment on the locus, reasonably in same auxiliary contact unitary space, increased a pair of auxiliary contact, for practical application is provided convenience.
2, by adjusting installation site and the contact direction of static contact component contact direction and moving contact component, pattern that can two pairs of auxiliary contact unit of flexible transformation, comprise two pairs of normally open contacts or a pair of normally open contact and a pair of normally closed interlock, further satisfy user's application demand.
