Abstract
The utility model relates to an electric-heating film, particularly an electric-heating film for the overheating protection of a power supply lead wire thermosensitive switch. The goal of the utility model can be realized by the method that the utility model is composed of an electric-heating film, power supply lead wires of the electric-heating film and metal sheets connected with a power supply. The utility model is characterized in that the power supply lead wires of the electric-heating film or the metal sheets connected with the power supply are connected with the thermosensitive switch in series. The utility model has the advantages that the power supply can be automatically switched off after the temperature of a contact resistance which is arranged on the electric connection position of the power supply lead wires of the electric-heating film and the metal sheets connected with the power supply rises to a definite degree because the power supply lead wires of the electric-heating film or the metal sheets connected with the power supply is connected in series with the thermosensitive switch, therefore the safety of the electric-heating film can be ensured in use.
Description
The utility model relates to a kind of Electric radiant Heating Film, the Electric radiant Heating Film of particularly a kind of power supply lead wire thermoswitch overtemperature protection.
Electric radiant Heating Film is with safety, advantages such as it is even to generate heat are widely used in heating, fields such as electric heating, Electric radiant Heating Film itself is very thin, therefore the power supply lead wire of Electric radiant Heating Film is also very thin, at very thin Electric radiant Heating Film power supply lead wire, it is electrically connected with external power supply, the general practice also adopts one to connect the very thin sheet metal of power supply, this sheet metal that connects power supply is crimped on by mechanical mode with the Electric radiant Heating Film power supply lead wire is electrically connected, but this mechanical connection manner, certainly will produce contact resistance at the contact point of metal, and the size of its resistance directly influences the heating temperature rise of this contact point, contact resistance is bigger, and then the temperature rise of this contact point is also higher, because contact point can produce temperature rise, add mechanical connection metal material temperature distortion Stress Release and electrodynamic effect, will produce sparking at contact point, short circuit, even initiation fire have stayed hidden danger for the operation of Electric radiant Heating Film safety at the contact point place.
In view of this, how to avoid the syndeton of Electric radiant Heating Film and power supply to produce dangerous situations such as sparking after heating, make that the user of Electric radiant Heating Film can relieved use, the utility model grinds wound motivation place just.
The utility model designer, does a brand-new design and constitutes on the basis of feasibility study repeatedly by means of being engaged in the practical experience that all kinds of electrothermic instruments are researched and produced processing and other fields for many years, gets generation of the present utility model eventually.
At the deficiencies in the prior art; the purpose of this utility model is the Electric radiant Heating Film of a kind of power supply lead wire thermoswitch of design overtemperature protection; make the junction of Electric radiant Heating Film power supply lead wire and power supply sheet metal after the temperature of contact resistance is raised to a certain degree; the energy automatic shutdown circuit; avoid producing sparking and wait dangerous situation, improve the usage safety performance of Electric radiant Heating Film.
The purpose of this utility model can be by following realization, and the utility model is made of the power supply lead wire of Electric radiant Heating Film, Electric radiant Heating Film, the sheet metal that connects power supply, it is characterized in that the power supply lead wire of Electric radiant Heating Film or connects serial connection one thermoswitch on the sheet metal of power supply.
The utility model is further characterized in that thermoswitch is arranged on the junction of power supply lead wire with the sheet metal that is connected power supply of Electric radiant Heating Film, and thermoswitch can adopt bimetal release.
The utility model advantage is serial connection one thermoswitch on the power supply lead wire of Electric radiant Heating Film or the sheet metal that connects power supply, make when the power supply lead wire of Electric radiant Heating Film with after the electrical connection place contact resistance temperature of the sheet metal that is connected power supply is elevated to certain program, automatically cut off the electricity supply, guarantee the safety in the Electric radiant Heating Film use.
Further illustrate the utility model embodiment below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
The utility model is made of the power supply lead wire 4 of Electric radiant Heating Film 3, Electric radiant Heating Film, the sheet metal 1 of connection power supply, at the power supply lead wire of Electric radiant Heating Film or connect serial connection one thermoswitch 2 on the sheet metal of power supply, thermoswitch 2 is detected temperatures automatically, after temperature is raised to a certain degree, and automatic disconnection; The power supply lead wire 4 of Electric radiant Heating Film can be a sheet metal, and same, the sheet metal 1 of power supply also can plain conductor.
The utility model thermoswitch 2 is arranged on the junction of power supply lead wire 4 with the sheet metal 1 that is connected power supply of Electric radiant Heating Film, thermoswitch can directly be felt the temperature rise of contact resistance, thermoswitch 2 can adopt bimetal release, when bimetal release is raised to certain altitude in temperature, because the degree of crook difference of two metal sheets when temperature raises, contact point is disconnected, disconnect entire circuit with this.
In sum, the utility model makes contact resistance after temperature raises by serial connection one thermoswitch in the power supply connecting circuit, can cut off the electricity supply automatically, stops to produce the possibility that electricity is cremated.Obviously the utility model is the new design of a kind of novelty, progress and dark tool practicality.The above is specific embodiment of the utility model and the know-why used, if the equivalence of doing according to conception of the present utility model changes, when the function that it produced does not exceed spiritual that specification and accompanying drawing contain yet, all should be in scope of the present utility model, explanation hereby.
