Abstract
The utility model relates to a protection against electric shock electric plug has prevented effectively that the electric plug is in the problem of using front and back electric leakage accident. Protection against electric shock electric plug includes metal contact -piece protective housing (1), metal contact -piece (2), spring fixing column (3), insulating casing (4), expanding spring (5), flexible activity groove (6) and connects wires (7) outward. The utility model has the advantages that: be connected with under expanding spring's the protective housing, metal contact -piece and socket can tightly be connected, have effectively avoided the outside naked condition of conducting strip, prevent effectively that the electric shock accidents from taking place.
Description
Technical field
This utility model is related to appliance field, specifically provides a kind of protection against electric shock plug.
Background technology
As commonly used electric equipment in our daily life, known plug is by metal contact piece, inside to plug
Circuit and plastics outer box three part composition, as long as the outside exposed part of plug conductive sheet is longer mould although holding during using
Metal contact piece is inserted into socket and can make circuit ON by material shell, but in using, finger is directly touched conducting strip and is easy to send out
Raw electric shock accidentss, especially for for the heavier child of curiosity it is easier to finger be reached two metals of point socket plug
Between contact, thus leading to get an electric shock.In daily, such plug has serious potential safety hazard.For this reason, need one kind badly can
The plug of protection against electric shock.
Utility model content
In order to solve above-mentioned technical problem, this utility model provides a kind of protection against electric shock plug.
This utility model is achieved in that a kind of protection against electric shock plug, and described protection against electric shock plug includes metal contact piece
Containment vessel, metal contact piece, spring fixed column, insulation crust, coil tension spring, telescopic movable groove and external cord, described external electricity
Line one end is fixedly connected with metal contact piece, and one end is connected with external power supply, and described spring fixed column is placed in insulation crust, and with
Metal contact piece containment vessel is connected, and described spring fixed column is fixed with coil tension spring, and metal contact piece containment vessel is built-in with one and stretches
Loose slot, described metal contact piece is tangent with telescopic movable groove.
A kind of this utility model protection against electric shock plug, equipped with a metal contact piece containment vessel on described metal contact piece.
A kind of this utility model protection against electric shock plug, described insulation crust is built-in with a coil tension spring.
A kind of this utility model protection against electric shock plug, described metal contact piece containment vessel passes through spring fixed column and coil tension spring
It is connected.
A kind of this utility model protection against electric shock plug, the Extensible of described coil tension spring is equal to metal contact piece insertion and inserts
The length of seat.
Compared with prior art, the utility model has the advantage of:
This utility model when plug metal contact piece insertion socket, receive under the action of the spring by metal contact piece containment vessel
Contracting, the length that metal contact piece containment vessel shrinks is equal to the length that metal contact piece inserts socket.When plug comes out of the socket,
Metal contact piece containment vessel automatic spring under the action of the spring.Metal contact piece and socket can be made in whole process tightly to connect
Connect, be prevented effectively from metal contact piece leakage and cause injury of getting an electric shock, and improving cost is low, simple to operation.
Brief description
Below in conjunction with the accompanying drawings and embodiment is described in further detail to this utility model:
Fig. 1 is this utility model protection against electric shock plug top cross-sectional view.
Fig. 2 is this utility model protection against electric shock plug vertical section structure schematic diagram.
Specific embodiment
Referring to Fig. 1-2, a kind of protection against electric shock plug that this utility model is related to, described protection against electric shock plug includes metal
Contact containment vessel (1), metal contact piece (2), spring fixed column (3), insulation crust (4), coil tension spring (5), telescopic movable groove (6)
With external cord (7), described external cord (7) one end is fixedly connected with metal contact piece (2), and one end is connected with external power supply, institute
State spring fixed column (3) to be placed in insulation crust (4), and be connected with metal contact piece containment vessel (1), described spring fixed column (3)
On be fixed with coil tension spring (5), metal contact piece containment vessel (1) is built-in with a telescopic movable groove (6), described metal contact piece (2) with
Telescopic movable groove (6) is tangent.
Equipped with a metal contact piece containment vessel (1) on described metal contact piece (2).
Described insulation crust (4) is built-in with coil tension spring (5) structure, and it is solid that described metal contact piece containment vessel passes through spring
Fixed column is connected with coil tension spring.
The Extensible of described coil tension spring (5) is equal to the length that metal contact piece (2) inserts socket.
When using, that is, during plug metal contact piece (2) insertion socket, metal contact piece containment vessel (1) is flexible
Withdraw in the presence of spring (5), the length that it shrinks inserts the equal length of socket with metal contact piece (2), when plug metal
When contact (2) comes out of the socket, metal contact piece containment vessel (1) and automatic spring in the presence of coil tension spring (5).
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with the accompanying drawings and implement
Example, is further elaborated to this utility model.It should be appreciated that specific embodiment described herein is used only for explaining
This utility model, is not used to limit this utility model.
