Abstract
An overheat resistant multi-jack socket adopts the structure that a normally-closed temperature relay is accessed to a wire connected with the interior of a socket, the wire can be either a neutral wire or a live wire, and the temperature relay is connected in parallel with an LED. The overheat resistant multi-jack socket has the advantages of low probability of overheating, avoidance of burnout, high safety factor, reduction of fire hazards, and the like.
Description
Technical fieldThe utility model relates to a kind of auxiliary power supply.
Background technologyIn recent years, the frequency that fire disaster takes place is more and more higher, great personnel and property loss have been caused, and electrical equipment is because overheated to cause burning be one of major reason of taking place of fire, insert row is a kind of as socket, its overheated phenomenon often takes place, and the overheated reason of insert row is on the one hand because the power of electrical equipment is excessive, causes the overheated of entire circuit; Be exactly the contact problems of appliance plug and insert row on the other hand, the metal spring leaf folder of the insert row inside of using in the daily life is normally made with monolithic, the weakness of this structure is that the heating back produces strain, exist voltage drop between insert row in the use and the plug, there has been the voltage drop insert row will consume a part of power, be about to electric energy and be converted into heat energy, the power of the big more consumption of voltage drop is big more, and it is serious more to generate heat; After socket service time was long, the monolithic of socket inside was aging, contact badly to produce " spark " through regular meeting, take place simultaneously " " sound, so the overheated not only coefficient of safety of insert row is low, and easy initiation fire.
Summary of the inventionThe purpose of this utility model is to provide a kind of and is difficult for overheatedly, avoids burning out, and the coefficient of safety height reduces the anti-overheated insert row that fire takes place.
The scheme that the utility model adopted is:
With the inner wire that links to each other of insert row on access closed type temperature relay, said wires can be that zero line also can be a live wire, described temperature relay is in parallel with a light-emitting diode.
Flow through the electric current of light-emitting diode for minimizing, damage light-emitting diode, above-mentioned light-emitting diode is connected with a current-limiting resistance.
The utility model is that realization is anti-overheated like this: for temperature relay is provided with to fixed temperature, usually be 50 ℃ to fixed temperature, when the temperature in the insert row is lower than to fixed temperature, temperature relay short circuit light-emitting diode, main circuit is connected, and this moment, light-emitting diode was not luminous; When the temperature in the insert row reached to fixed temperature, temperature relay discharged and disconnects, and main circuit is disconnected, and light-emitting diode is lighted; Realize the constant temperature power down function by said structure.
The utility model compared with prior art has following advantage: insert row is difficult for overheated, avoids burning out insert row, and coefficient height safe in utilization reduces fire and takes place; Simple to operate, easy to use.
Description of drawingsFig. 1 is a structural representation sketch of the present utility model.
EmbodimentIn the structural representation sketch of anti-overheated insert row shown in Figure 1, with access closed type temperature relay 3 on the insert row 1 inner live wire 2 that links to each other, temperature relay is in parallel with light-emitting diode 4, and light-emitting diode is connected with current-limiting resistance 5.
Claims (2)
1. anti-overheated insert row is characterized in that: with the inner wire that links to each other of insert row on access closed type temperature relay, described temperature relay is in parallel with a light-emitting diode.
2. anti-overheated insert row according to claim 1, it is characterized in that: light-emitting diode is connected with a current-limiting resistance.
