Abstract

The disclosed power switch plug comprises an upper/lower shell, a contact, and the key-type or push-pull switch devices on fire wire and zero wire in shell. Wherein, the key-type switch comprises the key, key connection rod and the conductive spring pieces arranged on key two sides symmetrically; the push-pull switch comprises the push-pull key with conductive pieces, the junction plate and the connection plate both arranged on key sides symmetrically. This integrated product is convenient to usage, saves energy, and has long service time for wide application.

Description

Power supply switch plug

One, technical field

The present invention relates to attaching plug, particularly a kind of power supply switch plug.

Two, background technology

As everyone knows, existing attaching plug is to install two or three conducting strips on the collets, by being wired on the electrical appliance.This plug exists following shortcoming or deficiency: though 1. some electric equipments are stopped using, if do not pull up attaching plug, still at consumed power, waste energy first, second increased customer charge; 2. often unplugg can cause wall socket to become flexible or come off, and phenomenons such as sparking take place in loose contact, cause short circuit sometimes, even lead to a disaster, and shorten the useful life of plug and socket.

Three, summary of the invention

The purpose of this invention is to provide a kind of power supply switch plug, adopt push-button switch device, it can prevent effectively or overcome shortcoming or the deficiency that exists in the above-mentioned prior art, the fail safe that improves equipment effectively, prevent energy waste, prolong the useful life of plugs and sockets.

Another object of the present invention provides a kind of power supply switch plug, adopt the push-pull switch device, it can prevent effectively or overcome shortcoming or the deficiency that exists in the above-mentioned prior art, the fail safe that improves equipment effectively, prevent energy waste, prolong the useful life of plugs and sockets.

Power supply switch plug of the present invention, comprise, lower house, also comprise the live wire contact of installing on the lower house, the zero line contact, ground wire contact and comprise button, the switching device of connecting rod for keys and electroconductive elastic sheet, it is characterized in that described switching device is the button structure, be installed on the upper shell, electroconductive elastic sheet is serpentine or returns hook-shape structure, its upper end is installed on the upper shell of button both sides symmetrically, contact with button, the electroconductive elastic sheet lower end is a free end, described electroconductive elastic sheet lower end between the upper end inner side plane of live wire contact and zero line contact, and with this plane mutually folding cooperate.

Power supply switch plug of the present invention, comprise the live wire contact and the zero line contact of housing and the parallel installation in its underpart and comprise the push-and-pull key, conducting strip, the push-pull switch device of lug plate and brace, it is characterized in that described push-and-pull key is installed on the housing side, lug plate and brace symmetry are installed on push-and-pull key both sides, described conducting strip is installed on push-and-pull key inner surface, and be provided with two grooves on it at least, on live wire contact and zero line contact, be respectively equipped with described brace, described lug plate is a rectangular configuration, with the corresponding at grade installation of described brace, one end and the housing of described lug plate fix, other end end simultaneously is provided with at least one projection that matches with groove on the conducting strip, another side is installed on and makes described lug plate and conducting strip maintenance support spring at grade, one end of described brace is connected with contact, other end end simultaneously is provided with at least one projection that matches with groove on the conducting strip, and another side is installed on and makes described brace and conducting strip keep at grade support spring.

The present invention has following advantage compared with prior art:

1, plug and switch integral structure are easy to install, and the supporting use of complete and existing socket also is applicable to single-phase any electric equipment;

2, energy savings as long as turn off the switch that is provided with on it, can be cut off the power supply, and does not have electric current to pass through fully;

3, avoid the trouble of plug plug constantly, eliminate because of frequent plug plug cause the loosening and loose contact generation of socket sparking, open circuit, potential safety hazard such as short circuit, prolong its useful life.
