Abstract
The utility model relates to a multifunctional display type safe socket. Three LED indicating lamps are arranged on a panel; each LED is connected in series with a resistor; the anode of one LED and the cathode of one LED are connected with splicing pieces of a live wire power supply; the cathodes of two LEDs are connected with splicing pieces of a zero wire power supply; the anodes of two LEDs are connected with splicing pieces of a ground wire through a resistor. The correct connection and the operating state of the live wire, the zero wire and the ground wire are displayed through the luminescence of three diodes. The utility model has the advantages of simple structure, convenient and accurate construction, installation and inspection, and safe use.
Description
The utility model relates to the supply socket technical field.
At present, the general common socket of Shi Yonging, it has only a kind of single function of supplying power, and to exist in the socket circuit wrong and install improperly, can not understand by an order, and for example: do not protect ground wire, do not have working zero line, live wire and zero line connect instead, do not have live wire.In normal use, also can be owing to reasons such as misoperations, ground protection, the zero connection protection of socket itself are caused come off the fail safe of influence use; Quality examination station in building trade, quality manage inspection personnel such as station and electric section chief to the problems referred to above must be one by one in construction and installation progressively inspection, even in construction and installation, the personnel that some quality are relatively poor, also can get by under false pretences individually less than the problems referred to above because of checking, thereby influence the use of socket and user's safety.
The purpose of this utility model provides a kind of light-emitting diode that utilizes different colours, shows the multi-functional display type safety socket of socket wiring state.
For achieving the above object, the utility model is taked following design: a kind of multi-functional display type safety socket, panel, jack are arranged, and the electric power connecting sheet is arranged in the jack; Panel is provided with 3 indicator lamp holes, in indicator lamp hole, be provided with the light-emitting diode of different colours, it is more than withstand voltage 250V, resistance of each light-emitting diode series connection, wherein the negative pole of the positive pole of a light-emitting diode, a light-emitting diode is connected with live wire electric power connecting sheet, the negative pole of two light-emitting diodes is connected with zero line electric power connecting sheet, and the positive pole of two light-emitting diodes is connected with the ground wire insert-connecting plate by resistance.
After adopting above-mentioned circuit to connect, when the construction and installation socket, can pass through the luminous of 3 diodes, show whether the connection of live wire, zero line, ground wire correctly reaches operating state.
The utility model is described in further detail below in conjunction with accompanying drawing.

Embodiment
As shown in Figure 1 and Figure 2: a kind of multi-functional display type safety socket, panel 7, jack are arranged, the electric power connecting sheet is arranged in the jack, panel 7 is provided with 3 indicator lamp holes 1, in indicator lamp hole 1, be provided with the light- emitting diode 2,3,4 of different colours, resistance 10 of each light-emitting diode series connection, wherein the negative pole of the positive pole of a light-emitting diode 2, a light-emitting diode 3 is connected with live wire electric power connecting sheet 6, the negative pole of light- emitting diode 2,4 is connected with zero line electric power connecting sheet 5, and the positive pole of light-emitting diode 3,4 is connected with ground wire insert-connecting plate 8 by resistance 10.
If light-emitting diode 2 is red, light-emitting diode 4 is green, and light-emitting diode 3 is yellow.
Red, yellow, green three kinds of light-emitting diodes can show 6 kinds of wiring states (red light emitting diodes 2, yellow light-emitting diode 3, green LED 4 are called for short red, yellow, green).(1), red, Huang Liangshi, expression wiring correct (as shown in Figure 2), red light emitting diodes 2 forward conductions, burn red, yellow light-emitting diode 3 is the reverse-conducting obfuscation, owing to diode is selected for use more than the withstand voltage 250V, when the voltage reversal of 220V is pressurizeed diode 3 two ends, can not cause puncture, experiment shows, during the reverse connection work of diode 3, also is conducting state, just resistance is greater than forward, and is luminous dark.(2), red, green when bright, expression live wire 11 connects instead with zero line 12, promptly red light emitting diodes 2 and green LED 4 reverse-conductings are luminous, yellow light-emitting diode 3 two ends equipotentials are then not luminous.(3), yellow, green when bright, expression live wire 11 connects instead with protection ground wire 9, promptly yellow light-emitting diode 3 and green LED 4 two ends forward conductions are luminous, red light emitting diodes 2 two ends equipotentials are not luminous.(4), three lamps are bright entirely; green is dark slightly; expression does not have zero protection; zero line 12 is off state; be yellow light-emitting diode 3 reverse-conductings jaundice light, red light emitting diodes 2 is series connection with green LED 4, and the former is reverse-conducting for the forward conduction latter; so produce certain pressure drop at green LED 4 two ends, make green LED luminous dark slightly.(5), three lamps are bright entirely, yellow is dark slightly, expression does not have the ground wire protection, ground wire 9 is off state, be that red light emitting diodes 2 forward conductions glow, yellow light-emitting diode 3 is series connection with green LED 4, and the former is a reverse-conducting, jaundice light is dark slightly, and the latter is the forward conduction green light; (6), three lamps do not work entirely, expression does not have live wire, promptly live wire 11 access failures are off state.
The circuit of socket can be installed in the rear portion of panel 7, and live wire joint 11 is connected with right insert-connecting plate 6, and zero line joint 12 is connected (i.e. a left side zero right fiery connection) with left insert-connecting plate 5, and middle insert-connecting plate 8 is connected with earth connection point 9; During the construction and installation socket, connect wrong or access failure as if live wire, zero line, ground wire, then the indicator light of three red, green, yellow looks can demonstrate wiring and whether correctly reach on off operating mode, also is convenient to the construction Supervision inspection simultaneously, and an order is understood, and can prevent trouble before it happens.
The utility model has the advantages that: simple in structure, easy to manufacture, cost is low, constructability is installed correct With inspection, safe and reliable.
