Embodiment

Extremely shown in Figure 6 as Fig. 1, the utility model embodiment provides a kind of power-line plug loop, the plug 1 that comprises wire loop and be located at wire loop one end, and wire loop is provided with the construction of switch that is used to connect and turn-off wire loop, operates this construction of switch and just can turn on and off the appliances power source that links to each other with this power-line plug loop.

Particularly, plug 1 is three grades of plugs of national standard, wire loop comprises live wire incoming line 2, load line 3, zero line 4 and ground wire 5, and construction of switch comprises body glue spare 6, is arranged at live wire input pin 7 and live wire output pin 8 on the body glue spare 6, and the operating assembly of between live wire input pin 7 and live wire output pin 8, connecting and turn-off operation, live wire incoming line 2 two ends are connected on respectively on plug 1 and the live wire input pin 7, load line 3 one terminates at live wire output pin 8, and the other end is connected to electric appliance load.

And operating assembly comprises the button 9 that cooperatively interacts, offset plate 10 resets, back-moving spring 11, stroke movable block 12, push rod 13 and shell fragment 14, shell fragment 14 1 ends are provided with the input terminal silver tipped contact 15 that links to each other with live wire input pin 7, the live wire output pin 8 of input terminal silver tipped contact 15 belows is provided with lead-out terminal silver tipped contact 16, button 9 is arranged at offset plate 10 tops that reset, back-moving spring 11 1 ends are connected to body glue spare 6 inner support panels 17, the other end is connected to offset plate 10 belows that reset, and the activity of the offset plate 10 that resets is limited between body glue spare 6 upper surfaces 18 and the inner support panels 17, stroke movable block 12 can be rotatably set in shell fragment 14 tops, and input terminal silver tipped contact 15 1 ends of stroke movable block 12 are connected to button 9 belows by push rod 13, the other end is connected to an end of shell fragment 14 homonymies, the middle part of shell fragment 14 places on body glue spare 6 one fulcrums 18, wherein, button 9 can adopt red transparent material, sets and presses to opening, projection is for closing.

When concrete operations, pressing button 9 is stressed, and push rod 13 and stroke movable block 12 are to pressing down and trigger shell fragment 14 1 ends, and shell fragment 14 other ends and input terminal silver tipped contact 15 contact to pressing down with lead-out terminal silver tipped contact 16, cause the live wire incoming line 2 and the circuit of load line 3 to connect electric appliance load work; When needs are closed appliances power source, pressing button 9 is stressed, push rod 13 and stroke movable block 12 are pulled upwardly shell fragment 14 1 ends, shell fragment 14 other ends and upwards action of input terminal silver tipped contact 15, separate with lead-out terminal silver tipped contact 16, cause the live wire incoming line 2 and the circuit of load line 3 to disconnect, electric appliance load quits work.

In order to increase the self-protection function of construction of switch, shell fragment 14 is a kind of bimetallic thermal sensitive piece, and it can be when circulation electric current wherein causes its heating to produce deformation, the bimetallic thermal sensitive piece that input terminal silver tipped contact 15 is separated with described lead-out terminal silver tipped contact 16.Like this; under the circuit on-condition of live wire incoming line 2 and load line 3; when electric current is excessive in the circuit; bimetallic thermal sensitive piece meeting abnormal heating; when temperature surpassed its rated temperature, deformation can take place and upspring in the bimetallic thermal sensitive piece, and input terminal silver tipped contact 15 is separated with lead-out terminal silver tipped contact 16; thereby cut off the circuit of live wire incoming line 2 and load line 3, protected electric appliance load.What deserves to be mentioned is in the time of excessive protection of load current, no matter whether button 9 is subjected to pressed by external force, this construction of switch can both carry out overload protection automatically, can not automatically reset simultaneously.

In order to make construction of switch good looking appearance and non-dismountable safe in utilization and durable to guarantee, construction of switch is outside equipped with gluing shell 19 and reaches the protection structure of glue shell 20 compositions down, gluing shell 19 and glue shell 20 employing ultrasonic waves weldings down.

In order to protect wire loop; the end that is positioned at the construction of switch both sides of wire loop is respectively arranged with line shelves 21; line shelves 21 are a kind of in the outside shaped structures of wire loop; can prevent the excessive and outer quilt of damage electric wire of wire loop pulling force; avoid producing bad order and the bad problem of electric property; be specially adapted to roving electrical equipment, as percussion drill, electric hand drill, dust catcher etc.

For whether the power-line plug loop is switched on indicate, also be provided with the switch on indicator light of indication, the holder of indicator light on the body glue spare 6, and be connected respectively to the lamp base 23 on indicator light and the zero line 4.

In order to increase overvoltage; surge; the surging protection; also be provided with piezo-resistance 22 between load line 3 and the zero line 4; the parameter of piezo-resistance 22 is decided on working voltage; as domestic common use 14D471N; wherein 14D is meant the external diameter 14mm of piezo-resistance; 471N is meant that voltage is 470V; in fact also be divided into direct current and exchange; when exchanging, can move under this specification, when external factor such as three-phase four-wire power supply line zero thread breakage, when former 220V becomes the 380V power supply to 330V; electrical equipment can damage because of overtension; and after increasing piezo-resistance 22, can sense the unusual of supply power voltage fast, piezo-resistance 22 inner resistances become quite little fast; load current becomes very big simultaneously; this switch is fast break under the situation of overcurrent, thereby has protected electrical equipment, increases piezo-resistance 22 and undoubtedly electrical equipment has been increased by a heavily protection more.

As a kind of execution mode, above-mentioned plug 1 can also be a national standard secondary plug, does not just comprise above-mentioned ground wire 5 in the so corresponding wire loop, specifically can decide according to the product actual demand.

Applicable various family expenses in the power-line plug loop of the utility model embodiment or industrial electric apparatus, following single-phase household electrical appliance of electric current 15A/ voltage 250V etc. for example, be particularly useful for electric tool, kitchen appliance, and the electrical equipment that does not have the control of ac dump switch, as be equipped with the power-line plug loop of the utility model embodiment, not with the electrical equipment of ac dump switch under the situation of a shared multipurpose socket, when one of them electrical equipment does not use, just do not need to pull up again its plug, and directly to switch structure operation turn off its power supply and get final product, simple to operation.For example, electromagnetic oven does not have the ac dump switch, after finishing using, do not pull up plug if just turn off the mains switch on the electromagnetic oven, the surface seems that Panel light does not work, and in fact electromagnetic oven goes down not only can cause the electricity consumption waste for a long time still in electricity consumption, and have fire safety evaluating hidden danger, if adopt the power-line plug loop of the utility model embodiment, then need not to pull up plug, only need push its construction of switch and get final product.

Need to prove that disclosed multiple construction of switch all can be adapted to according to actual needs and form a plurality of embodiment in the power-line plug of the present utility model loop in the prior art, the embodiment that increases is too within the utility model protection range certainly.

The above is an embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also are considered as protection range of the present utility model.
