Description

Temperature protector

Technical field

The utility model relates to a kind of temperature protector, is specifically related to that a kind of normal operating conditions is often opened and when the closeable temperature protector of excess temperature, belongs to the electric switch technology.

Background technology

The existing temperature detect switch (TDS) that is connected on this similar temperature protector in the power consumption equipment circuit all is by the bimetallic thermal switching element, and is normally closed in normal operating conditions, disconnect at the excess temperature state, thereby the work of realization control electricity consumption working equipment.

In the application process of industrial production or industrial products, such as needing the occasion institute mounted fan of ventilation and heat, perhaps at industrial products computer fan of being used for lowering the temperature or the like for example, for saves energy, under the operating ambient temperature condition, said fan should quit work, and under operational environment excess temperature condition, said fan is worked just now.This can not realize above-mentioned requirements for existing this class temperature detect switch (TDS) that is in normally off.

Summary of the invention

The purpose of this utility model is, a kind of temperature protector that is used to protect the working equipment under the operational environment excess temperature condition is provided, to save the power consumption of cooling system.

The utility model realizes that the technical scheme of its purpose is,

A kind of temperature protector, have by the insulation contact base, conduction first contact that one end can be electrically connected with external wire, the conduction the second wafer that one end can be electrically connected with external wire is formed and is provided with the electric switch assembly that the bimetal leaf of contact is formed at an end of first reed by first reed and second reed; The contact can be docked with first contact, and first contact and the second wafer are chimeric fixing with contact base respectively, and the other end of bimetal leaf is electrically connected with the other end of the second wafer, and its improvement is: the contact of bimetal leaf and first contact are often opened.

Can understand by above given technical scheme, the utility model is because the contact of its first contact and bimetal leaf, both often open under the ambient temperature normal condition, and only under environment excess temperature condition, auto-closing starts cooling system just now, thereby has realized the purpose of this utility model.

The further improvement of the utility model point is:

Also has the uncovered heat-conducting metal shell of an end; Outer cover suit is in the outside of electric switch assembly.Its purpose obviously is further to keep the good operation condition for the electric switch assembly.

The second wafer is provided with the projection that constitutes via bending, the bottom surface of a projection top bimetal leaf; The end face of first reed of bimetal leaf is provided with notch.Because the existence of the projection of the second wafer can further effectively be avoided because the fatigue of bimetal leaf is surrendered, and produce the contact of bimetal leaf and the closed conducting of first contact; And, can further help the contact of bimetal leaf and the disconnection and the closing motion of first contact because the notch of bimetal leaf exists.

After technique scheme is implemented, what the utility model had is simple and reasonable, can start the cooling system work with the working equipment phase configuration under working equipment operational environment excess temperature condition, thereby characteristics such as saves energy consumption are conspicuous.
