Abstract

The utility model discloses a power line plug with a switch, which comprises a shell and three pins respectively connected with a phase line, a zero line and an earth line. The power line plug is characterized by also comprising the switch which is arranged on the shell and controls the phase line to be connected with the pin corresponding to the phase line. The power line plug is provided with the switch which controls the phase line to be connected with the pin corresponding to the phase line on the shell of the plug, after the plug is connected with a power socket by insertion, if needing to use an electrical appliance, the switch is pressed or toggled to put through the connection between the phase line and the corresponding pin, and the electrical appliance can be used; after finishing usage, the switch is pressed or toggled again to separate the connection between the phase line and the corresponding pin, and the plug does not need to be pulled out. After switching off through the switch, the connection between the plug and the power socket by insertion does not consume power any longer without pulling the plug out, thus increasing safety. Furthermore, the power line plug with the switch is convenient and practical, avoids the trouble that the power plug of the electrical appliance needs to be inserted and pulled out for one time when being used for one time, strengthens the reliability of the connection between the plug and the socket and electric conduction, and is applicable to the power line plugs of various electric appliances.

Description

The power-line plug of belt switch

Technical field

The utility model relates to a kind of electrical installation, especially the plug of appliances power source line.

Background technology

Existing electrical equipment, as electric cooker, printer, washing machine, smoke exhaust ventilator and air conditioner or the like, general all is to peg graft with corresponding supply socket by the plug of power line to obtain electric energy, and these electrical equipment all will be extracted plug after finishing usually, separate with supply socket.Otherwise the part of devices in the electrical equipment is also in energising, the one, and electricity wasting, the 2nd, dangerous, the more important thing is that every usefulness once will be inserted once to pull out plug one time, very trouble.And one of plug and socket inserted one and pulled out, and is easy between the two damage, and causes loose contact, uses also inconvenient.

Summary of the invention

The purpose that the utility model relates to provides a kind of power-line plug of belt switch, and it can solve the weak point of existing power supply line plug, makes power-line plug safety and convenient and practical.

The technical solution of the utility model is:

A kind of power-line plug of belt switch, it comprises housing and three pins that are connected with phase line, zero line and ground wire respectively, it is characterized in that also comprising:

Be located on the described housing, control the switch that described phase line and corresponding phase line pin connect.

The housing of plug is provided with the switch that control phase line and corresponding phase line pin connect, after plug and supply socket are inserted mutually and are connected, if need make electrical appliance the time, then by or the connection of toggle switch connection phase line and corresponding pin, soon power connection just can make electrical appliance.With after finishing, again by or toggle switch disconnect the connection of phase line and corresponding pin, power remove soon, can not will plug extract.Owing to disconnected the connection of phase line and corresponding pin by switch, electricity has led in any device less than electrical equipment.So under the situation of electrical appliance not, after the switch outage, plug and supply socket be slotting to be connected and need not to have pulled the plug out of the socket also not power consumption again, has increased fail safe.And, convenient and practical, avoided the every usefulness of appliances power source plug once will insert the trouble of once pulling out once, strengthened the reliability that plug and socket connects and conducts electricity.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Shown in Figure 1, be main TV structure schematic diagram of the present utility model.Among Fig. 1, on plug casing, be provided with switch 2, above the top protrusion plug casing loam cake 1 of this switch 2, be convenient to operation; Power line 3 is from the right side input of plug casing.Revolve right TV structure schematic diagram Fig. 3 after turning 90 degrees in conjunction with backsight structural representation Fig. 2 of Fig. 1 and Fig. 1, and Fig. 1 look up structural representation Fig. 4, power line 3 comprises phase line L, zero line N and earth connection.Wherein, from the utility model circuit theory schematic diagram shown in Figure 5 as can be known, phase line L is by switch 2 and corresponding pin 8 connections, and whether the energising of pin 8 is subjected to the control of switch 2, the pin 5 that zero line N is direct and corresponding connects, and the pin 8 that earth connection is direct and corresponding connects; Three pins 5,6,8 all are triangle at interval with following 4 of housing and are fixedly connected; The loam cake 1 of housing is fixedly connected by screw 7 with following 4, and is identical with the structure of existing power supply line plug.In this legend, press " 0 " end of switch 2, then connect phase line L and corresponding pin 8, press "-" end of switch 2, then disconnect.Certainly, the pattern of switch 2 can also be stirred or twist switch, uses for convenience also to be located at the corresponding side of housing.Switch 2 is prior art products, can buy on the market relevant.The switch of other pattern also can buy on the market relevant, all can play control phase line L by switch and corresponding pin 8 connections, can choose the pattern of switch according to the need and possibility.

Claims (1)

1, a kind of power-line plug of belt switch, it comprises housing and three pins that are connected with phase line, zero line and ground wire respectively, it is characterized in that also comprising:

Be located on the described housing, control the switch (2) that described phase line (L) and corresponding phase line pin (6) connect.
