Abstract
The utility model relates to a pulling-free plug composed of a plug body and a boat-shaped switch. The utility model is characterized in that the utility model overcomes the problems that after a single-phase three-core grounding plug for the existing domestic appliance is used, the plug must be pulled out of a socket, and the plug is easy to damage electric wires or makes the socket loosen. As long as a button is pressed, a power supply can be effectively turned on or turned off, and the utility model can also display the condition whether the turnon or the turnoff and the grounding of a circuit on the power supply is good or not. The utility model is an ideal pulling-free plug adopting a three-core grounding plug in domestic appliances.
Description
A kind of plug, particularly a kind of Pulling-free plug.
At present, household electrical appliance such as air conditioner, electric heater, electric kettle, electric chafing dish, electric cooker etc. all are to adopt single-phase three core ground pins, because the particularity of above-mentioned these electrical equipment, the power supply of control section or load is not disconnected up hill and dale, custom was that direct three-prong plug with electric equipment products inserts supply socket (can not produce spark when being disconnected as load) when people used, and finished using and plug was extracted from socket again.The bigger electrical equipment of power consumption particularly, for the contact resistance of avoiding plug, socket excessive, all adopt and fit tightly, so plug inserts, all very hard when extracting, and fragile socket or make socket, electric wire loosening, be absolutely unsafe, result in hand cramps for the family that uses these class household electrical appliance and cause some unnecessary loss.
The purpose of this utility model is: the three-prong plug that a kind of household electrical appliance use is provided is when inserting, power supply is turned off, can insert safely, finish using and will not extract by plug, the power supply of electrical equipment thoroughly can be disconnected, go back the display power supply ground connection Pulling-free plug whether good indicator light shows that has that it's too late simultaneously.
Technical solution of the present utility model is: a kind of Pulling-free plug, it is made up of header body and rocker type switch two parts, it is characterized in that: the lower end of header body 1 is fixed with three pins 2 that match with socket
L, 2
N, 2
E, the upper end has a rectangle chute of inlaying rocker type switch, the lower end of rocker type switch shell 3 be equipped with three with pin 2
L, 2
N, 2
EThe binding post 4 that is connected respectively
a, 4
b, 4
c, the upper end is movably hinged with a ship shape button 5, and neon bulb 6 is housed in the ship shape button 5, and a lead of neon bulb 6 connects contact 4
c, another root lead connects resistance 7, and the other end of resistance 7 is connected with camber touch panel 9 again.This plug is after institute's connecting circuit is closed, and presses button 5 again, then under the effect of spring 8, make the contact of camber touch panel 9 leave binding post 4 and circuit is thoroughly disconnected, the neon bulb extinguishes simultaneously, finishes appliance plug and need not extract, just the purpose that circuit can be disconnected.
The utility model has the advantages that: adopt three core ground pin electrical equipment, must not pull up plug, only need press button, the neon bulb extinguishes, just can thoroughly electrical equipment and power supply thoroughly be disconnected, guarantee the safety that electrical equipment uses, and whether good the display power supply ground connection that has that it's too late Presentation Function arranged.
That the utility model will be further described is as follows below in conjunction with accompanying drawing:
Accompanying drawing is the structural representation of Pulling-free plug
The utility model is made up of skewer head body and two parts of rocker type switch, the lower end of header body 1 is installed with three pins 2 that match with three core sockets, there is a rectangle chute upper end, be used to install rocker type switch, the E pin of pin 2 directly links to each other with E, the N lead of electrical equipment three heart yearns respectively with the N pin, the binding post 4 of L pin below lead and rocker type switch shell 3
aLink to each other L lead and 4
bLink to each other the E pin of pin 2 and binding post 4
cConnect by lead.After supply socket is inserted in the pedicure 2 of skewer head, press the button 5, under the effect of spring 8, make the contact of camber touch panel 9 be pressed in binding post 4
aOn, at this moment, the power supply of the L utmost point is switched on, and electrical equipment enters operating state, because neon bulb 6 and binding post 4
c, 4
bConnect, lighted so neon bulb 6 is connected, display circuit is working properly.When oppositely pressing button 5, under the effect of spring 8, binding post 4 is left in the contact of camber touch panel 9
a, then circuit is disconnected, and 6 on neon bulb extinguishes, and indication circuit is obstructed.If the L of socket, N circuit have connect instead, the neon bulb does not then work.This plug disconnects in use and to connect circuit very convenient, removed household electrical appliance from when using three core ground pins, whether the trouble that plug must be pulled out after using can also be connected by display power supply simultaneously, whether ground connection is good, is the comparatively ideal Pulling-free plugs of household electrical appliance.
