Abstract

The utility model discloses a push-button type safe power-supply socket, belonging to the power-supply sockets which are used for plugging safely with various electric apparatuses in basic electric elements. The utility model is a composite element which combines the power-supply socket and a push-button switch. Generally, the sheet metal of the plug opening of the socket is not electrified. In use, electric energy can only be led out from a plug after the natural button in the middle of the plug opening is pressed by the plug. Therefore, the utility model has good electric shock-proof function. The sheet metal of the plug opening of the socket is longer than 5 millimeters to a traditional one, and thus can be firmly joined with the plug. Work is reliable. In addition, the push-button type safe power-supply socket has the advantages of convenient use, simple structure, long service life, and low cost.

Description

Push-button safety receptacle
The utility model belongs to and is applicable to the supply socket of doing various low-voltage electrical apparatus safe sockets in the basic electrical component.At present, the conventional electrical outlet that is widely used can play the grafting effect with plug, is the charged socket of socket sheet metal at ordinary times.The reason of using this supply socket people (particularly children) are often got an electric shock is: both sheet metals of moment that insert (or extracting) socket when hand-held plug have contacted and have constituted the loop, but finger (automatic or have little time) does not still break away from plug metal film and causes electric shock.This series products is inevitable because the socket sheet metal is in electriferous state always so human electric shock's accident takes place.What is more, virgin the disclosing into jack with iron nail, wire or pinkie of the object for appreciation that has got an electric shock, exactly because this product does not possess due to the safety prevention measure.
For " Sealed lock fixed pattern power safety socket " (patent No. 892144912) that just occurred on the market, this product is the charged safety socket of making the prevention of electric shock measure again of the Sealed lock fixed pattern of a kind of socket sheet metal, but on the socket panel, there is not the circular plug jack, so circular metal post plug just can not use, its reason is structurally to be afraid of that the bomb with steel balls that inside is used for sealing condition drops out.And in the household appliances of selling in the market, learn that it is the circular metal post that the import household electrical appliances have 35% attaching plug approximately according to my investigation of working on marketing, homemade household electrical appliances have 20% approximately.So just make the practicality and the popularization of this product have tangible limitation.In addition, this product also has a kind of inevitable electric shock situation to be: in the plug process of using, plug has been pushed the locking cover plate aside and charged, but finger does not still leave plug metal film and gets an electric shock.Moreover this product must be established the sealing lockplate of one deck thickening more, so that the socket module is done lock motion, makes small product size increase complex structure like this, and cost is inevitable more expensive.Simultaneously, when plug inserts translation motion need be arranged, using not enough direct convenience to go wrong easily is its shortcoming.
Another patented product that does not still appear on the market " the multi-functional automatic safety socket of exempting to get an electric shock " (patent No.: 92239776.6), " this socket has good protecting function to electric leakage, electric shock, overvoltage, overcurrent, short circuit ".According to introducing this is a kind ofly to do the product of security protection with all electronic circuit, has the employed electronic components of several like this functions (discrete component) dozens of will be arranged.Therefore; " 44 yuan of every cover integrated cost valencys; every assembling takes 9 yuan " (Workers Daily; advertisement on November 5 in 1993) adds business management expense etc.; the market price will be more than 70 yuan; so multifunctional protection, complex structure, expensive supply socket; do not design (the household electrical appliance socket is generally used less than overvoltage, overcurrent protection) for domestic household; it is applicable to laboratory or medium and small individual vendor; if add not easy care of electronic product, estimate to promote towards the society to have difficulties.
Also having four cellular type supply sockets that patent recently, add a pair of jack on original 2 jack center lines, only is the safety prevention measure that do not possess easy to use.
The purpose of this utility model is to overcome the shortcoming that traditional supply socket does not possess the prevention of electric shock measure.Make the existing function of safety protection of this product life-span simple in structure again long, use traditional plug to peg graft equally conveniently without locking mechanism and electronic circuit, and reliable operation, low price reaches the purpose of popularizing as early as possible.
The push button safety power source plug socket is a kind of push-button switch and the synthetic electric component of common socket.When this socket inserts (or extracting) at plug, plug does not touch before the nature button as yet, and the socket sheet metal is not charged always, has only when the plug bottom surface touches button and it has just been pressed, the button plush copper is pushed reed open and is contacted the conducting of circuit ability with the socket sheet metal to the both sides.And at this moment between plug bottom surface and the receptacle face, only remaining 2~3 mm distance, finger can not be stretched extremely, so it has good electroshock-proof function.
After plug presses the button the circuit connection, because the socket sheet metal grows 5 millimeters than traditional socket, it can firm grip plug metal film (or metal column), and it can not fallen down automatically, holding circuit continues well, so this socket has the advantage of reliable operation again.
With reference to the accompanying drawings the utility model is elaborated:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a loam cake view of the present utility model.
Fig. 3 is a structural plan of the present utility model.
Referring to Fig. 1: two power lines insert base screw [3] [4] below the base [1] that insulate, on two-screw, fixing two elastic sheet metals [5] [6] simultaneously, this reed does not join with other two socket sheet metals [7] [8] that are fixed on the base at ordinary times, each self-sustaining 1~1.5 mm distance between the two, thus the uncharged at ordinary times safety function of socket sheet metal [7] [8] guaranteed.The socket sheet metal uses the rubber-like copper sheet to make, to clamp plug metal film or metal column, the reliable contact of holding circuit.
Referring to Fig. 1, Fig. 2: socket loam cake [2] can be manufactured with transparent plastic for the contact situation of observing inner reed, the jack [9] [10] that the common power socket is arranged above the lid, cylinder or sheet metal plug are inserted, and just in time upward socket sheet metal [7] [8] position is corresponding with insulator foot [1] for this jack.Central authorities at two jacks are provided with button oblong aperture position [11], and insulation button [12] passes capping in the hole, and expose the height of 2~3 millimeters of cappings.The button plush copper [13] of button [12] bottom is just clamping between two charged reeds [5] [6], and when button [12] when being pressed by plug, button plush copper [13] just promotes charged reed [5] [6] and connects in twos with socket sheet metal [7] [8], through plug derivation electric energy.When socket was extracted, along with extracting of plug, button plush copper [13] was boosted by elastic spring [5] [6] at plug, and button [12] sets back, and charged reed [5] [6] leaves socket sheet metal [7] [8] under elastic force simultaneously, keeps uncharged safe condition.
