Abstract
The utility model discloses a novel power plug, mainly solving the problem that the existing power plug can not show the power on condition. The utility model is characterized in that a power indication circuit formed by a rectification diode (4), a LED tube (5) and a current-limiting resistor (6), all of which are connected in series consequentially; a hole is arranged on a plug body (7) and used as the display hole of the LED tube (5). The novel power plug can not only be connected with a socket to form an on circuit but also indicate the power on condition and judge that an electric appliance or equipment can not be started if because the socket is broken or in loss of power.
Description
Technical field:
The utility model relates to a kind of power supply auxiliary connecting device that is used on the household electrical appliance, relates to a kind of attaching plug specifically.
Background technology:
The existing attaching plug that is used on the household electrical appliance only has the function that is connected turning circuit with socket, situation about can not display power supply connecting.Consequent use problem is: if the power supply indicator of electrical equipment that it was communicated with or equipment is bad, or there is not an indicator light, for example electric power plug socket, charger etc., in case electrical equipment or equipment can't start so,, when using, brought some inconvenience for the user actually the user can't judge that or its reason socket damages the socket dead electricity.
The utility model content:
In order to solve the problem that existing attaching plug can not display power supply be connected, the utility model provides a kind of novel power supply plug, this kind novel power supply plug not only has the function that is connected turning circuit with socket, but also can indicate power on situation, can judge accurately that electrical equipment or equipment can't start whether to damage or the socket dead electricity causes by socket.
The technical solution of the utility model is: this kind novel power supply plug, comprise header body, metal electrode inserted sheet and be connected in conventional structures such as power lead on the described metal electrode inserted sheet by housing pin, its unique distinction is: comprise a power indicating circuit that constitutes after being connected successively by rectifier diode, LED light-emitting diode and current-limiting resistance in the described novel power supply plug, perforate on the described header body is as the display aperture of described LED light-emitting diode.
The utlity model has following beneficial effect: novel power supply plug described in the utility model, owing to wherein also comprise a power indicating circuit, in this circuit, electric main is through becoming Rectified alternating current after the rectifies, entered by the positive pole of LED, and negative pole flows out, light light-emitting diode, and through the current limliting of current-limiting resistance in the loop, it is very low to make that electrorheological in the circuit gets, and the entire circuit power consumption maintains in the 10mA.Whether therefore, this kind novel power supply plug not only has the function that is connected turning circuit with socket, but also can indicate power on situation, can judge accurately that electrical equipment or equipment can't start to be damaged by socket or the socket dead electricity causes.In addition, fixing, movable power socket electrical verification usefulness that this kind novel power supply plug can also can be used as, the fluorescent illumination that also can be used as night in the room is used.Whether this kind of novel power supply plug, can be used for detecting all kinds of sockets and switches on because the small and exquisite electroscope that replaces of volume is carried when as the electrical verification time spent.Because safety socket is all adopted in wall mounted supply socket now, the pin that two jacks of socket must be inserted simultaneously plug can use, therefore advantage in this is that electroscope is incomparable, especially uses advantage more obvious when the building electric final acceptance of construction.In being used for the room at night, use during fluorescent illumination, it directly can be inserted in the wall mounted supply socket, use as night light.Because power is very little, does not produce heat, can use for a long time.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation after the utility model inserts power lead.
Fig. 3 is the schematic diagram of power indicating circuit described in the utility model.
Fig. 4 is an end view of the present utility model.
Fig. 5 is a vertical view of the present utility model.
1-metal electrode inserted sheet among the figure, the 2-housing pin, the 3-power indicating circuit connects lead, 4-rectifier diode, 5-LED light-emitting diode, 6-current-limiting resistance, 7-header body, 8-power lead, the anti-folding of 9-lead sheath.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, this kind novel power supply plug, comprise header body 7, metal electrode inserted sheet 1 and be connected in conventional structures such as power lead 8 on the described metal electrode inserted sheet by housing pin 2, its unique distinction is: comprise a power indicating circuit that constitutes after being connected successively by rectifier diode 4, LED light-emitting diode 5 and current-limiting resistance 6 in the described novel power supply plug, its circuit theory diagrams as shown in Figure 3, and perforate on the described header body 7, as the display aperture of described LED light-emitting diode 5, as shown in Figure 4.
During use, electric main becomes Rectified alternating current through rectifier diode D rectification, is entered by the positive pole of LED, and negative pole flows out, and lights light-emitting diode, and the current limliting through current-limiting resistance R makes that the electrorheological in the circuit gets very low.
During concrete enforcement, rectifier diode and current-limiting resistance are encapsulated in the idle component in the plug, the perforate that the LED light-emitting diode inserts on the shell is exposed at the end outside the housing, adopt Instant cement or chloroform gluing fixing between light-emitting diode and the plug body perforate, rectifier diode and current-limiting resistance are all by the afterbody of thin wire soldering at inserted sheet, distance is bigger between the inserted sheet, and the space is comparatively spacious in the jack body, does not influence normal wiring.Because the entire circuit power consumption is very low, the entire circuit power consumption maintains in the 10mA, and current-limiting resistance can be selected the 1/8W fixed carbon resister for use, to save the space, saves cost.
And the utility model also can be used for multiple attaching plug, for example two-phase, three-phase, four phase plugs etc.In addition, can also be at the afterbody of described header body, promptly power lead draw the place, fix the anti-folding of lead sheath 9, bend for a long time to avoid lead, insulation sheath is broken.
Claims (2)
1. novel power supply plug, comprise header body (7), metal electrode inserted sheet (1) and be connected in power lead (8) on the described metal electrode inserted sheet by housing pin (2), it is characterized in that: comprise a power indicating circuit of connecting successively and afterwards constituting in the described novel power supply plug by rectifier diode (4), LED light-emitting diode (5) and current-limiting resistance (6), described header body (7) goes up perforate, as the display aperture of described LED light-emitting diode (5).
2. novel power supply plug according to claim 1 is characterized in that: the afterbody of described header body (7), promptly power lead (8) draw the place, fix the anti-folding of lead sheath (9).
