Abstract
The utility model relates to a plug with the surge prevention and the overload protection, comprising a casing, a surge prevention capacitor and an overcurrent protector, wherein, two convex and unclosed conducting sheets are arranged on one side face of the casing, wherein, one conducting sheet is connected with one terminal of the surge prevention capacitor, the overcurrent protector is contained in the casing, two convex and unclosed sheet bodies are arranged on one end face of the overcurrent protector, wherein, one sheet body is connected with the other terminal of the surge prevention capacitor, the other sheet body is connected with the other conducting sheet, the two sheet bodies are connected in parallel with two terminals in which a warning lamp, a rectifying diode and a resistor are connected in series, and the end face corresponding to the two sheet bodies is provided with a function return button. When the electricity consumption of the plug is overloaded, the overcurrent protector is in the power-off state, at this point, the warning lamp is lightened to reach the safe protection of the overload plug, after the user inspects and completely eliminates the overload situation, the function return button of the overcurrent protector is pushed to make the plug return to the normal operation, and at this point, the warning lamp is extinguished.
Description
Technical field
The utility model relates to the plug that a kind of tool protrusion-dispelling involves overload protection; relate in particular to a kind of being available for users to after getting rid of plug generation overload condition; reply button as long as push the function of current protector, can make this plug return to the safety device of normal operation state.
Background technology
Various electric equipment products (as plug), be in the progressive civilized society institute in response to and the product of life gives unlimited convenience of user and enjoyment.When various electric equipment products are used, all must supply with electric equipment products with electric power, these electric equipment products are operated.And the combining of electric power and electric equipment products, really make us obtain a lot of facilities on the living conditions, yet these electric equipment products in use, and are easily old because of it, use and to overload or because of factors such as improper uses, and cause danger, damage or electric wire cocks off etc. as electric equipment products inside spare part, it is the most dangerous wherein to cock off with electric wire again, therefore, the incident that meets accident when how to avoid the electric current overload, an important topic.
See also the Taiwan patent announcement No. 55285; the plug that it discloses a kind of attached overload protection and caution comprises base, bimetal leaf and loam cake, and the characteristics of this patent are when using the electric current overload; this bimetal leaf promptly can cause and open circuit with the protection electric equipment products because of the reverse escape of temperature-sensitive.
The plug of another kind of overload protection; as No. the 488566th, Taiwan patent announcement; it comprises interior die holder, the first terminal, second terminal, blocks sheet, conductive tabs, spring and loam cake; when overload takes place in this plug; conductive tabs can surpass predetermined temperature; extend via different metal temperatures; make conductive tabs produce deflection; at this moment; the conductive junction point of conductive tabs contact and produce outage, and, block that elasticity that sheet is subjected to spring is shored and to outer displacement; and block the contact of two conductive junction points fully, reach the safeguard protection of plug overload.
Learn in view of the above,, so after this current overload situation occurred is got rid of, can not return back to normal operating condition though aforesaid plug can reach the generation of the disaster that prevents an accident when current overload takes place for it.
If can one its situation that current overload takes place is excluded after, still can reply the plug of normal operating condition, must increase the practicality and the convenience of this plug.
Summary of the invention
The purpose of this utility model is to provide one to be available for users to after getting rid of plug generation overload condition, replys button as long as push the function of current protector, can make this plug return to the alarming device of normal operation state.
For realizing this purpose, the utility model makes the conducting strip on the side of plug casing connect an anti-surging electric capacity, and in housing, be installed with an overcurrent protective device, one end face of this overcurrent protective device is provided with the lamellar body of two protruding dew, wherein a lamellar body is connected with the other end of anti-surging electric capacity, another lamellar body then is connected on another conducting strip, button mutually and connect is replied with a function is arranged on the corresponding end face of this two lamellar body in the two ends that this two lamellar body and a warning component, a rectifier diode and a resistance are in series; When the electricity consumption of this plug is transshipped; overcurrent protective device then can be off-position; at this moment; warning lamp sends light; reach the safeguard protection of this plug overload, after the user inspects and the situation eliminating of overload will take place, push the function of this overcurrent protective device again and reply button; make this plug recover normal operation, this moment, this warning lamp extinguished.
