Abstract
The utility model discloses a two-path overload protection plug, which relates to the improved technology of overload protection plugs. The two-path overload protection plug comprises a base, an upper cover of a shell is arranged on the base, a pin and an external wiring terminal are mounted under the base, and the external wiring terminal is covered by a connecting box; the base is provided with a solenoid valve release, a solenoid valve release contact is mounted at the inner end of the solenoid valve release, an operation piece is mounted under the pin, an operation piece contact is mounted on the operation piece, and the operation piece contact is opposite to the solenoid valve release contact; the external wiring terminal is connected with a null line and live line leaf spring, the null line and live line leaf spring is provided with a null line and live line contact, the null line and live line contact is located under the solenoid valve release, a connection piece is arranged under the null line and live line contact, and the connection piece is connected with a connection piece contact; and the connection piece is further provided with an operation piece static contact, and the operation piece static contact is opposite to the operation piece contact. The two-path overload protection plug solves the problems that the wire is electrified and has the danger of causing electric shock when a null line and a live line of the conventional similar products are connected inversely, and the like.
Description
Technical field
The utility model relates to the improvement technology of overload protection plug.
Background technology
Overload protection plug in the market all is that single channel is broken off, and when the zero live wire of circuit connects inverse time, electric wire has charged and danger that get an electric shock easily.
The utility model content
The utility model provides a kind of two-way overload protection plug, and the utility model has solved existing like product and connect inverse time when the zero live wire of circuit, and electric wire has charged and problems such as danger that get an electric shock easily.
For addressing the above problem, the utility model adopts following technical scheme: two-way overload protection plug, comprise base 7, and outer casing upper cover 1 is arranged above the base 7, pin 10 is installed below the base 7 and connects exterior lines terminal 9, connect exterior lines terminal 9 outsides and be covered with terminal box 8;
Electromagnetically operated valve release 11 is installed on the base 7; Electromagnetically operated valve release 11 the inners are equipped with electromagnetically operated valve release contact 19; Pin 10 belows are equipped with action movie 20, and action movie contact 18 is installed on the action movie 20, and action movie contact 18 is relative with electromagnetically operated valve release contact 19;
Connect exterior lines terminal 9 and connect zero live wire shell fragment 13, odd live wire contact 15 on the zero live wire shell fragment 13, zero live wire contact 15 is positioned at electromagnetically operated valve release 11 belows, and there is a brace 14 zero live wire contact 15 belows, and brace contact 16 is arranged on the brace 14; On brace 14, also have an action movie break 17, action movie break 17 is relative with action movie contact 18.
The two-way overload protection plug of the utility model is applicable to that all electrical appliances such as all following household electrical appliance of 5500W, electric equipment play overload and short-circuit protection.When circuit overload and short circuit, zero line and live wire are cut off simultaneously, and keep the thoroughly outage of plug back, protection electrical equipment, property and life safety.
Through in the two-way overload protection plug circuit when current overload or short circuit; Action movie produces high temperature through big electric current; The action movie short time set is connected action movie contact and electromagnetically operated valve release contact when reaching the action movie operating temperature, and energising of electromagnetically operated valve release and dropout make zero live wire shell fragment lose pressure and flick the power supply that cuts off zero line and live wire fully simultaneously and keep off-position; After maintenance is normal, need connect work once more, then press the release SR, connecting indicator light bright is that electrical equipment recovers operate as normal.
