Abstract
The utility model discloses an energy-saving and safe power plug line, which comprises a power line (1), a shell (2), plugging columns (3), a switch (4), an indicator lamp (5), a resistor (6) and a fuse (7), wherein the plugging columns (3) are connected with the power line (1) and are fixed on the shell (2); the power line (1) is serially connected with the switch (4), the indicator lamp (5) and the fuse (7); the switch (4) is parallelly connected with the resistor (6); and the switch (4) and the indicator lamp (5) are fixed on the shell (2). The energy-saving and safe power plug line is used for a high-power household appliance without a switch, and is safely and reliably connected with the conventional power plug without a switch, and the service life of the household appliance is prolonged; and moreover, a small amount of electric spark is generated when the energy-saving and safe power plug line is used, electric energy loss is low, and the purpose of saving energy is achieved.
Description
Technical field
The utility model is specifically related to a kind of energy-saving safety power plug wire.
Background technology
Present a lot of power surpasses 1000 watts, 1500 watts household electrical appliance, as the electric heater of the usefulness of heating up water, electric chafing dish, electric frying pan etc., self does not have belt switch, all directly inserts socket with ordinary plug to be connected with power supply on-load operation closure and disconnection process.In the plug process, the electric current of plugs and sockets carrying reaches more than the 7A, and on-load is large, directly during the plug plug, switch on or off power supply moment at every turn, will inevitably produce electric spark, electrically contact the ablated oxidation of place's meeting, and loose contact, so that contact resistance strengthens, the plug heating, increased the excess loss of electric energy, reduced the heat efficiency of kettle, the electrode contact place of plugs and sockets easily heating burns out, can cause the insulating barrier of plugs and sockets to damage, thereby further cause serious accident.
The utility model content
The technical problem that (one) will solve
The technical problems to be solved in the utility model provides a kind of energy-saving safety power plug wire.
(2) technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of energy-saving safety power plug wire, comprise power line 1, housing 2, inserting column 3, switch 4, indicator light 5, resistance 6, fuse 7, described inserting column 3 is connected connection with power line, and be fixed on the described housing 2, described power line 1 series connection described switch 4, indicator light 5 and fuse 7, described switch 4 described resistance 6 in parallel, described switch 4 and indicator light 5 are fixed on the described housing 2.
Silver-plated or the platinum of the contact surface of described switch 4.
The light-emitting component of one end of described inserting column 3, the button of switch 4, indicator light 5 is exposed at outward outside the described housing 2.
(3) beneficial effect
The utility model is large and self domestic electric appliance of belt switch not for power, safe and reliable when the existing power supply plug of belt switch is not connected when adopting this plug, the extension device life-span, and also the electric spark that produces when using is few, the electric energy of loss is few, reaches energy-conservation purpose.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
A kind of energy-saving safety power plug wire as shown in Figure 1, comprise power line 1, housing 2, inserting column 3, switch 4, indicator light 5, resistance 6, fuse 7, described inserting column 3 is connected connection with power line, and be fixed on the described housing 2, described power line 1 series connection described switch 4, indicator light 5 and fuse 7, described switch 4 described resistance 6 in parallel, described switch 4 and indicator light 5 are fixed on the described housing 2.
Silver-plated or the platinum of the contact surface of described switch 4.
The light-emitting component of one end of described inserting column 3, the button of switch 4, indicator light 5 is exposed at outward outside the described housing 2.
During use, first switch is disconnected, plug is inserted inserting column, indicator light is not bright, the resistance of at this moment connecting on the circuit, and electric current is little, therefore can not produce electric spark, Closing Switch then, indicator light is bright, make resistive short, begin normal operation, although in Closing Switch, the switch place also can produce electric spark, but switching speed is fast in the time of closed, only produces a small amount of spark.And contact surface adopts silver-plated or the anti-oxidant high-temperaure coating such as platinum, has increased useful life.Also be serially connected with fuse on the circuit, improved security performance.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
Claims (3)
1. energy-saving safety power plug wire, comprise power line (1), housing (2), inserting column (3), switch (4), indicator light (5), resistance (6), fuse (7), described inserting column (3) is connected 1 with power line) connect, and be fixed on the described housing (2), it is characterized in that: described power line (1) connect described switch (4), indicator light (5) and fuse (7), described switch (4) described resistance in parallel (6), described switch (4) and indicator light (5) are fixed on the described housing (2).
