Description
Technical Field
The utility model belongs to the technical field of the temperature control protector, specifically speaking relates to a temperature control protector of too big electric current.
Background
Temperature control protector wide application in fields such as domestic appliance and industrial electricity, its theory of operation is when the overload use appears in the circuit, the electric current in the circuit sharply increases, if discovery and open circuit in time, the condition of burning out will take place, through concatenating into temperature control protector in the circuit, be equipped with high sensitivity temperature-sensitive element bimetallic strip in the temperature control protector, when the temperature sharply risees, the bimetallic strip takes place to be out of shape, and then open circuit, the electric current that present temperature protector can pass through is all smaller, can not play effectual protection when passing through the heavy current, this is the not enough of prior art.
In view of this, the present invention is provided.
SUMMERY OF THE UTILITY MODEL
This utility model adopts the basic concept of the technical proposal that:
the utility model provides a control by temperature change protector of too big electric current, includes the bottom plate, be provided with on the left side of bottom plate and throw the point, the left side of throwing the point is provided with the contact, be connected with the shell fragment on the contact, the shell fragment all has electric conductivity with the bottom plate, be connected with bimetallic strip on the upper end of shell fragment, the upper end of bimetallic strip links together with the upper end of bottom plate, be provided with the subassembly of moulding plastics on the lower extreme of bottom plate, be connected with first wiring mouth on the bottom plate, be connected with second wiring mouth on the subassembly of moulding plastics.
The bottom plate, the elastic sheet and the bimetallic strip are riveted together, and the contact, the elastic sheet, the injection molding assembly and the bottom plate are also riveted together.
The lower part of the throwing point is L-shaped, and the upper part of the throwing point is provided with a triangular supporting point.
The middle part of the elastic sheet is provided with an arc-shaped protruding node.
The elastic sheet and the bottom plate are both made of metal materials.
After the technical scheme is adopted, compared with the prior art, the utility model following beneficial effect has.
The utility model discloses access wire forms the return circuit in first wiring mouth and second wiring mouth, when reaching the active temperature of bimetallic strip when the high temperature, the bimetallic strip can take place deformation and push the contact open, and the circuit disconnection, when the temperature dropped to a certain temperature, the bimetallic strip reset, has the rerouting.
The utility model discloses.
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
Drawings
In the drawings:
fig. 1 is a schematic view of the front side of the structure of the present invention.
In the figure: 1-a bottom plate; 2-polishing points; 3-injection molding the component; 4-a first wiring port; 5-a second wiring port; 6-contact; 7-a spring plate; 8-bimetallic strip.
Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments, and the following embodiments are used for illustrating the present invention, but do not limit the scope of the present invention.
As shown in figure 1, the temperature control protector for the overlarge current comprises a bottom plate 1, a polishing point 2 is arranged on the left side of the bottom plate 1, a contact 6 is arranged on the left side of the polishing point 2, the contact 6 is not connected with the polishing point 2, an elastic sheet 7 is connected on the left side of the contact 6, the elastic sheet 7 and the bottom plate 1 are both made of conductive metal materials, a bimetallic strip 8 is connected on the right side of the upper end of the elastic sheet 7, the bimetallic strip 8 is of a structure capable of deforming according to the temperature, the upper end of the bimetallic strip 8 is connected with the upper end of the bottom plate 1, an injection molding assembly 3 is arranged on the lower end of the bottom plate 1, a first wiring port 4 is connected on the bottom plate 1, a second wiring port 5 is connected on the injection molding assembly 3, after a lead is connected into two access ports, the current of the lead in the second wiring port 5 sequentially passes through the contact 6, the elastic sheet 7, the bottom plate 1 and the first wiring port 4, and a path is formed, when the temperature is too high, the bimetallic strip 8 deforms to push the contact 6 and the elastic sheet 7 away, so that the contact 6 is separated from the lead in the second wiring port 5, and the circuit is disconnected.
The bottom plate 1, the elastic sheet 7 and the bimetallic strip 8 are riveted together, and the contact 6, the elastic sheet 7, the injection molding assembly 3 and the bottom plate 1 are also riveted together, so that the connection mode is not easy to loosen.
The lower part of the polishing point 2 is L-shaped, and the upper part thereof is provided with a triangular supporting point which can support the bimetallic strip 8 and prevent the lower end of the bimetallic strip 8 from contacting the bottom plate 1.
The middle part of the elastic sheet 7 is provided with an arc-shaped protruding node, so that the elastic sheet 7 and the contact 6 are more easily pushed away when the bimetallic strip 8 deforms at the time of overhigh temperature.
