Abstract

A safety socket relates to a power socket, in particular to a power socket that can automatically shut down the power when the current is too big. The utility model consists of a socket body, a safety device, a panel, a top cover and a containing box, and wherein, the safety device consists of first and second conductive sheets, a memory metallic sheet, a conductive sheet, an obstructing sliding sheet and a spring and is arranged in the containing space of the socket body. When the power is on, the first and second conductors of a plug are respectively connected with the first and second conductive sheets, and by means of the clamping body of the memory metallic sheet, the second conductive sheet is conducted with the conductive sheet via the throughhole of the obstructing sliding sheet. When the current is too big, the memory metallic sheet is contracted and drives the clamping body to separate from the throughhole of the obstructing sliding sheet, and the obstructing sliding sheet is forced by the spring to move up, so that the memory metallic sheet and the conductive sheet are in the power-off state, thus realizing automatic power-off. When the use continues after the big current is over, the memory metallic sheet is automatically reset, and the clamping body can be firmly clamped in the throughhole by pressing the top block of the obstructing sliding sheet, so that the power is on.

Description

Safety socket

(1) technical field:

The utility model relates to a kind of supply socket, particularly relates to a kind of safety socket that can cut off the power supply automatically when electric current is excessive.

(2) background technology:

Fire is modal contingency in the daily life, traces it to its cause due to electric wire cocks off often, and produces reason that electric wire cocks off normally because the electrical equipment improper use, just be easy to initiation fire as electric current when excessive, its point of origin is electric wire and socket just; Then cause by electric wire easily as electric wire is too old, otherwise just cause, so the use of socket seems particularly important by socket.With regard to general electrical equipment, when current loading is excessive, will cause conducting strip in the socket overheated and damage, the lighter will make electrical short-circuit and send and repair, and weight person then may cause the generation of fire.Existing socket is not owing to have any safety device, and therefore often electric current is excessive when using makes electrical equipment damage or cause not only to make troubles fire to the user, and very dangerous, and its practicality is very poor.

In view of this, the inventor is active development research, its can be suitable in addition to socket of the prior art improvement, and make it have more practicality, yet Providence doesn't let down a man who does his best at long last, the inventor is based on being engaged in this series products manufacturing experience for many years and long-term effort research and test, and development and Design goes out the utility model safety socket finally, and can all consumer and the industrial circles in Jiahui.

(3) summary of the invention:

The purpose of this utility model promptly is the improvement in addition suitable to the structure of existing socket, makes it can to cut off the power supply automatically when electric current is excessive, thereby avoids causing because of conducting strip is overheated the damage of electrical appliance or cause fire.

To achieve these goals, the utility model is set up a safety device that is made of first conducting strip, second conducting strip, memory metal sheet, conductive sheet, obstruct slide plate and spring in the accommodation space of jack body.First, second conducting strip is divided into first, second conduction bar of jack body, and a side of second conducting strip is provided with memory metal sheet; Memory metal sheet is the shape of falling V, and one bottom portion connects second conducting strip, and the other end then is convexly equipped with a card body, and the one side is provided with the obstruct slide plate; The appropriate location that intercepts slide plate is provided with the perforation that is used to fix the card body, and its top is provided with jacking block and can be placed in the jack body hole slot, and the jacking block below is arranged with spring, and the side of boring a hole is provided with conductive sheet in addition; Conductive sheet is provided with convex body and pushes up mutually and pull with the card body of perforation.

Based on above structure, during the utility model normal power-up, first, second conductor of plug is connected with first, second conducting strip respectively, and second conducting strip is then connected with conductive sheet via intercepting the slide plate perforation by memory metal sheet; When electric current was excessive, memory metal sheet Yin Wendu was too high and make to contract in its inverted V-shaped and drive its card body and break away from and intercept slide plate perforation, intercepts that slide plate will be subjected to spring force and upwards slippage, and memory metal sheet and conductive sheet are disconnected, thereby realize cutting off the power supply automatically.
