Description
Technical field
The present invention relates to an electronic parts, particularly a kind of socket.
Background technology
The socket of current use is generally its break-make of Non-follow control, can not automatically disconnect.Sometimes some local meeting timed on-off of power, is mainly the collective residential areas such as students' dormitory.The people in these places may close the switch of electrical equipment on socket when power-off, electrical equipment can automatically may be accidents caused when energized.Occur in the fire incident of some dormitories, cause owing to being automatically energized when electrical equipment is sent a telegram here after a loss of power again.
Summary of the invention
The purpose of this utility model is to provide a kind of safer power-off protection socket; after making to connect superincumbent appliance cut-off, incoming call can not be energized automatically again; electrical equipment is above protected, makes cannot automatically be energized when people's the unknown, avoid the generation of accident.
For achieving the above object, the technical solution of the utility model is: a kind of power-off protection socket, comprise magnetic linkage, linkage, manual connecting valve, metal spring, back-moving spring, power firestreak, zero-power line, earth connection, earth connection receptacle terminal, live wire receptacle terminal, electromagnet, hard contact, insulation crust, zero line receptacle terminal, below one end, electromagnet and back-moving spring are housed in described insulation crust, above electromagnet and back-moving spring, magnetic linkage is housed, manual connecting valve is provided with above magnetic linkage, connection linkage device above, linkage one end is connected with metal spring, the other end is rotationally connected insulation crust, the touch pole connection metal contact of linkage, power firestreak is connected magnet spool with zero-power line respectively by hard contact, and power firestreak is connected live wire receptacle terminal and zero line receptacle terminal with zero-power line respectively by hard contact.
A power supply indicator for reminding people's socket whether to connect energising is connected between live wire receptacle terminal with zero line receptacle terminal.Resistance is serially connected with between live wire receptacle terminal and magnet spool.
The beneficial effects of the utility model are:
After the utility model has aimed to provide a kind of power-off, power line and receptacle terminal are disconnected, continue after can making again to be energized to be in off-state with protection, connect the safety with this socket electrical equipment, can manually again connect.Electromagnet, metal spring, linkage, hard contact, wire forms decompression short-circuiting device, be connected with receptacle terminal power-off time can be connected by auto power off, and can not to connect after again sending a telegram here.Can manual ON when people need use.
In addition, the utility model also with the addition of a power supply indicator on socket, whether connects energising for reminding people's socket.
Accompanying drawing explanation
Fig. 1 is power-off protection socket structural representation of the present utility model.
Embodiment
Below by conducting further description the utility model with specific embodiment by reference to the accompanying drawings.
As shown in Figure 1; a kind of power-off protection socket, comprises magnetic linkage 1, linkage 3, manual connecting valve 2, metal spring 4, back-moving spring 12, power firestreak 5, zero-power line 6, earth connection 7, power supply indicator 8, earth connection receptacle terminal 9, live wire receptacle terminal 10, electromagnet 11, resistance 13, hard contact 14, insulation crust 15, zero line receptacle terminal 16.
In insulation crust 15, electromagnet 11 and back-moving spring 12 are housed below one end, electromagnet 11 and back-moving spring 12 are equipped with magnetic linkage 1 above, magnetic linkage 1 is provided with manual connecting valve 2 above, connection linkage device 3 above, linkage 3 one end is connected with metal spring 4, the other end is rotationally connected insulation crust 15, the touch pole connection metal contact 14 of linkage 3, power firestreak 5 and zero-power line 6 are connected the coil of electromagnet 11 respectively by hard contact 14, and power firestreak 5 is connected live wire receptacle terminal 10 and zero line receptacle terminal 16 with zero-power line 6 respectively by hard contact 14.
Being connected a power supply indicator between live wire receptacle terminal 10 with zero line receptacle terminal 16, whether connecting energising for reminding people's socket.Resistance 13 is serially connected with between the coil of live wire receptacle terminal 10 and electromagnet 11.
As shown in Figure 1, when metal spring 4 and back-moving spring 12 are all in compressive state, electromagnet 11 energising holds magnetic linkage 1.
When having a power failure, electromagnet 11 loses magnetism, and the effect due to back-moving spring 12 makes magnetic linkage 1 move upward, and acts on lower link device 3 to left movement simultaneously, hard contact 14 is disconnected at metal spring 4.
When again sending a telegram here, because circuit disconnects, electromagnet 11 is not energized nonmagnetic, so circuit can not automatic switching on.When user presses manual connecting valve 2, power on circuitry, electromagnet 11 produces magnetic will attract magnetic linkage 1 again.Socket and slotting superincumbent electrical equipment can work on.
