Description
Technical field
The utility model belongs to an electro-technical field, specially refers to a kind of Kick type temperature controller.
Background technology
The Kick type temperature controller that existing household electrical appliance use is mainly as temperature control, overtemperature protection etc., the moving contact of Kick type temperature controller product, static contact component and being connected of binding post are that the riveting pressure by rivet makes housing produce strain to strain respectively, while riveting in housing due to ailhead, because hindering rivet nut, ailhead cannot expand and shell fragment, determine fishplate bar interference fit, if interference fit is assembled again in advance, because shell fragment thickness only has 0.2 left and right, very easily loosening in assembling process, therefore, after long-term cold and hot work repeatedly, this tightening force can diminish gradually and cause contact resistance to become large, thereby affect life of product.
The patent No. is 98200816.3 to disclose a kind of < < with the Kick type temperature controller > > of rivet sleeve, it is equipped with rivet sleeve on the rivet as current-carrying element connector, and its two ends join with bottom and the binding post of contact assembly respectively.In the environment of high temperature, even if the elastic force of housing has relaxed, between current-carrying element, still can keep good connection by rivet sleeve.Although such scheme has solved the problem of loosing of rivet, increased the operation that rivet sleeve is installed, cost increases, and also easily omits nail cover, assembles also inconvenience and mould very fragile, and application is few at present.
Summary of the invention
The purpose of this utility model is to propose a kind of Kick type temperature controller, to improve the reliability of electrical connection of moving contact, fixed contact and binding post.
