Abstract

The utility model discloses a multifunctional display socket, wherein a resistor and an LED (light-emitting diode) are electrically and sequentially connected with each other by a guide wire and a socket binding post in a single phase socket. The multifunctional display socket can display whether a connecting wire for inserting a power supply into a socket is right, whether a power wire is broken and misconnected, and whether the socket has safety and reliable ground protection and whether electrical equipment has the problem of electric leakage.

Description

Multi-functional demonstration socket

Affiliated technical field

Whether the utility model relates to a kind of single-phase socket power supply wiring that shows correct, and whether the ground protection measure of security reliability and the device of electrical leakage are arranged.

Background technology

At present, known single-phase socket structure is by panel; Jack; Metal electrode film, binding post is formed.This structure can't display power supply inserts whether misconnection of live wire behind the socket, zero line, ground wire, and whether broken string and electric equipment leak electricity; If the generation misconnection, broken string, situations such as electrical leakage gently then can't normally be used; Heavy then jeopardize personal safety.

Summary of the invention

In order to solve the deficiency of existing single-phase socket function singleness, the utility model provides a kind of multi-functional demonstration socket, and this multi-functional demonstration socket not only has the function of common socket; And have that wiring is normal, live wire is disconnected, ground wire is disconnected, live wire and zero line reversal connection, live wire and ground wire reversal connection, electric equipment leak electricity Presentation Function.

The technical scheme that its technical problem that solves the utility model adopts is: with two groups of same LED, resistive element, one group of resistance is connected with LED is anodal, the anodal series connection of another group resistance and LED organized the LED negative pole composition parallel circuits that is connected to the other end of every group of resistance in two groups and another; Connect with LED is anodal with a resistance, a termination of LED negative pole and parallel circuits is gone into the zero line binding post of single-phase socket, and the resistance other end inserts the single-phase socket firewire binding post, and the other end of parallel circuits inserts the single-phase socket earth terminal.Wiring just often, LED1, LED2 are bright; Live wire disconnected then LED1, LED2 do not work, and the disconnected then LED2 of ground wire does not work; LED1, LED2, LED3 do not work when live wire and zero line reversal connection; Then LED3 is bright when live wire and ground wire reversal connection or electric equipment electric leakage, illustrates that circuit or electric equipment are abnormally dangerous.

The beneficial effects of the utility model are: whether whether the display power supply line correctly reach electric equipment and leak electricity intuitively; This circuit only adopts resistance, LED, components and parts few, and simple in structure.

Ground wire, R. resistance, LED. light-emitting diode (wherein LED1 is a sodium yellow, and LED2 is a green light, and LED3 is a red light).

Embodiment

Get the LED of three same different glow colors among Fig. 1, R2 one end is connected with LED2 is anodal, R3 one end is connected with LED3 is anodal, the R2 other end is connected with the LED3 negative pole, the R3 other end and LED2 negative pole end connect to form parallel circuits, R1 one end is connected with LED1 is anodal, LED3 negative pole and R2 link insert the zero line binding post of single-phase socket in LED1 negative pole and the parallel circuits, the R1 other end inserts the single-phase socket firewire binding post, and R3 and LED2 negative pole link insert the single-phase socket earth terminal in the parallel circuits.

On the single-phase socket panel, drill through three holes identical in the enforcement shown in Figure 2 so that fixed L ED and the luminous situation of observation directly perceived with the LED diameter.

Claims
