Abstract
A miniature quick-acting type temperature controller relates to the field of electrical apparatus elements, and comprises a shell body with an opening formed in one end, wherein a metal base plate is arranged inside the shell body, a pedestal and a static contact are arranged on the metal base plate, one end, far away from the static contact, of the pedestal is provided with a contact strip, a spring strip and a bimetallic strip are arranged in the shell body above the pedestal, the spring strip is stacked on the bimetallic strip, one end of each of the spring strip and the bimetallic strip is welded on the contact strip, the middle part of each of the spring strip and the bimetallic strip is supported on the pedestal, and the other end of the spring strip is provided with a moving contact matched with the static contact. The miniature quick-acting type temperature controller has the beneficial effects that: 1, the contact strip and the metal base plate are integrally combined through the pedestal which is formed by injection molding; 2, and the structure is simple and easy to implement, the free bimetallic strip technology is adopted, the temperature forming of the bimetallic strip is no longer affected by welding, the temperature forming yield is high, the product cost is reduced, the product internal resistance is less than that of similar products, the miniature quick-acting type temperature controller is more stable.
Description
Technical field
The present invention relates to electric elements field, be specially a kind of miniature snap-type temperature controller.
Background technology
Miniature snap-type temperature controller is a kind of temperature control and protection being widely used in battery protecting plate, integrated circuit and micromachine; it can experience and follow the change of ambient temperature; and in the cut-out of prefabricated temperature spot executive circuit; rising and control and defencive function, is the temperature sensing controller that a kind of temperature signal sensing and execution protection are integrated.
On market, like product all adopts the mode of bimetallic overcurrent, to reach the effect strengthening electric current induction sensitivity, this just necessarily increases critical technological point and manufacturing cost, as after bimetal leaf solder contacts, temperature discreteness is large, welding requirements is high, product internal resistance unstable.
Summary of the invention
The object of this invention is to provide a kind of structure and manufacture craft simple, and the miniature snap-type temperature controller that production cost is lower.
The technical scheme realizing above-mentioned purpose is: miniature snap-type temperature controller, comprise the housing of one end open, metal base plate is provided with in housing, metal base plate is provided with pedestal and fixed contact, pedestal is provided with contact chip away from one end of fixed contact, it is characterized in that: in the housing above pedestal, be provided with spring leaf and bimetal leaf, spring leaf overlays on bimetal leaf, one end of spring leaf and bimetal leaf is welded on contact chip, the midfoot support of spring leaf and bimetal leaf is on pedestal, the other end of spring leaf is provided with the moving contact coordinated with fixed contact, two wires are set in the openend of housing, a wire is electrically connected with metal base plate, another root wire is electrically connected with bimetal leaf, two are filled with epoxy resin between wire and housing.
Beneficial effect of the present invention: the pedestal 1, by injection mo(u)lding between contact chip and metal base plate merges into a single whole; 2, structure is simply easy to realize, and adopt free bimetal leaf technique, bimetallic temperature is shaping no longer to be affected by welding, and temperature profile yield is high.Product cost reduces, product internal resistance is less compared with like product, more stable; 3, bimetal leaf and spring leaf one step assembly welding, replaces first welding the total coating process of riveting afterwards.
Pedestal immediately below described contact chip is arranged through hole as welding electrode hole.
The position that the middle part of described pedestal is used for support spring sheet and bimetal leaf is provided with boss, increases the distance that dynamic and static contact is in released state
Described metal base plate is provided with the large bellmouth of young end opening, the lower end of described pedestal is entrenched in the bellmouth of metal base plate, strengthens the adhesion between pedestal and metal base plate.
Bimetal leaf is provided with the U-type groove avoiding moving contact near one end of moving contact, shorten the length of product.
The inwall of described shell nozzle end is provided with groove, and two epoxy resin of filling between wire and housing extend in described groove, are convenient to epoxy encapsulation.
Both sides, described housing upper surface angular position arranges chamfering, is convenient to identify temperature-sensitive face.
The upper surface bilateral symmetry of spring leaf near one end of moving contact is provided with salient point, as temperature correction point.Salient point free height every 0.02 millimeter one grade, temperature correction is simple and convenient, precision is high.
