Abstract
An adapter with insulation condition indicating function belongs to the electrical conduction and connection area. The utility model discloses a plug capable of showing the creepage of electric appliances. The technical proposal of the utility model is that a light-emitting diode and a current-limiting resistance are paralleled between the earth lead and the zero line contact of the adapter, the light-emitting diode and the current-limiting resistance can also be arranged between the earth lead and the zero line contact of the plug, a sparkle optical diode can also be used to replace the light-emitting diode. The utility model can be audio-visually judged whether the electric appliance creepage or not and the quantity of creepage can be judged. The utility model has low production, and excellent practicability and reliability.
Description
Technical field
The utility model belongs to conductivity interconnection technique field, is specifically related to a kind of socket that can show the electrical appliance leakage function, and international Patent classificating number is: H01R13/00.
Background technology
In our family life, can use various household electrical appliance, Electrical Safety is very important.The use of household electrical appliance be unable to do without supply socket.The socket of Chu Shouing generally all is single-phase three cores in the market, left side connecting to neutral line, the right side line of starting to exchange fire, the indirect ground wire is behind the switch that connects live wire, link to each other with zero line with light-emitting diode through a resistance, when switch was pressed in assurance, light-emitting diode was bright, and expression has, this light emitting diode lamp is installed on the socket, also can be installed on the plug.But there are the deficiency that can not indicate electrical appliance whether to leak electricity and leak electricity size in this socket or socket.
Summary of the invention
Goal of the invention of the present utility model provide a kind of can judge intuitively electrical appliance whether leak electricity and leak electricity the size a kind of with the electric leakage deixis insert row (seat).
The technical solution of the utility model is: be parallel with light-emitting diode and current-limiting resistance between the ground wire of socket and zero line contact.
Light-emitting diode and current-limiting resistance also can be installed between the ground wire and zero line contact of plug
Operation principle of the present utility model is: when electrical appliance leaks electricity, will produce voltage difference between the ground wire of socket and the zero line, the ground wire and the light-emitting diode between the zero line contact that are connected in parallel on socket will be bright, it is serious more to leak electricity, electrical leakage voltage is just big more, light-emitting diode is just bright more, takes measures with regard to having reminded the electric leakage of user power utilization device like this, avoids causing danger.
The utility model only needs to go up on the face of existing power supply slotting (row) or plug and bores a hole, is used for fixing the installation light-emitting diode, and the two poles of the earth of light-emitting diode join by the ground wire of current-limiting resistance and socket and the contact of zero line, and this expense is very low.
The utility model can judge intuitively electrical appliance whether leak electricity and leak electricity the size, have cheap, the good effect of practicality and good reliability.
Description of drawings
Fig. 1 is an electrical schematic diagram of the present utility model;
Fig. 2 is a structural representation of the present utility model.
Embodiment
As depicted in figs. 1 and 2, insert hole of brill on (row) 1 or the plug face at existing power supply, light-emitting diode 4 is installed in the hole, and the two poles of the earth of light-emitting diode 4 join by the ground wire of current-limiting resistance R and socket 1 and the contact of zero line, and the resistance of current-limiting resistance R is 300K Ω; Among Fig. 22 is mains switch.
In order to distinguish with power supply indicator 3, the color of electric leakage indicator light of the present utility model---light-emitting diode 4 should adopt the color that is different from power supply indicator.
For eye-catching, light-emitting diode 4 also can adopt flashing diode.
Claims (2)
1, the insert row (seat) of band electric leakage deixis is made up of socket (1), and it is characterized in that: in socket (1), be connected with light-emitting diode (4) and current-limiting resistance between the contact of ground wire and zero line, socket (1) face is exposed on the top of light-emitting diode (4).
2, the insert row (seat) of band electric leakage deixis according to claim 1, it is characterized in that: described light-emitting diode (4) is a flashing diode.
