Description
Technical field
The utility model relates to a kind of power supply wiring board, relates in particular to a kind of power supply wiring board of ship shape, particularly a kind of ship shape power supply wiring board with control switch.
Background technology
Wiring board claims socket, row Soviet Union again, at electrical appliances that is absolutely necessary such as family, factory, offices.In the world today is ubiquitous.We can say that wiring board plays an important role in life, work.But existing wiring board is also not fully up to expectations in design.It at first is its machine-made configuration design.Existing wiring board mostly is microscler or square box like structure.Simultaneously, do not have switch on the wiring board that has, what have does not then have an indicator light; Though what have has switch or an indicator light.But the two has only one.Even the existing switch of the wiring board that has has indicator light again, but do not accomplish that every group of jack all has a switch and indicator light.So, the electrical equipment that is inserted on the same wiring board can only be with opening with closing, if there is an electrical equipment to open, other will close, and then needs other appliance plug is extracted from wiring board, and is very inconvenient.In daily life, owing to network neutral line misconnection, virtual connection, reasons such as disconnection or threephase load imbalance often cause that fault overvoltage takes place, and can cause various household electrical appliance such as user's television set, computer to burn in flakes because of supply voltage is too high thus.Therefore the quick protection of line over-voltage has been an urgent demand of a large amount of household electrical appliance safe handlings.
On the other hand, the belt switch wiring board that people generally use at present, mains switch are arranged on and carry out single line between terminal stud and another conductor metal sheet and conduct switching with off state.When mains switch and power supply wiring termination and zero line join, after power supply disconnects, then just with it the zero line of homonymy be cut off, and the single circuit of the opposite side that mains switch is not set still joins with live wire, and load this moment does not quit work because of there being current circuit, and power supply has broken outwardly, but it is still charged with the single circuit that live wire joins, if someone stands on the ground and is not intended to contact metal the end of a thread or plug metal film with hand, then can take place to get an electric shock or beaten phenomenon by electric shock, fail safe is relatively poor.
Summary of the invention
The purpose of this utility model provides a kind of power supply wiring board, and a kind of power supply wiring board of ship shape especially is provided, and a kind of ship shape power supply wiring board with control switch is provided especially, overcomes the shortcoming of above-mentioned wiring board.
The purpose of this utility model is achieved through the following technical solutions:
A kind of power supply wiring board of ship shape is characterized in that: every group of jack of described wiring board is provided with branch position control switch.Described wiring board is provided with over-pressure safety device.
Described over-pressure safety device is with between a gas discharge tube parallel connection and zero line and the live wire; fuse and live wire are connected on the gas discharge tube front portion; in case there is overvoltage to appear at the gas discharge tube two ends; gas discharge tube will change conducting state over to by state of insulation rapidly; effectively with the overvoltage shorted to earth; short circuit current blows a fuse, thereby has effectively protected electrical appliance.
The electric connecting relation of above-mentioned wiring board all adopts existing be electrically connected principle and method.
The utility model is because adopted the configuration design of ship shape, and the effect of decorating the room, beautifying the environment had both been played in use, can satisfy normal electric power supply effect again.Collect attractive in appearance and be useful for the whole body.
The jack electrode structure of socket adopts the good phosphor-copper material structure of elasticity, therefore can with the plug reliable fit of different shape size, the sparking that loose contact causes often appears in the socket that has overcome ordinary construction and made.
Every group of jack all has a control switch, control switch is arranged on the live wire, pass through independent switch, can reliably control the break-make of power firestreak, need charged dangerous and trouble of pulling out, inserting plug when saving a plurality of electrical equipment and not using simultaneously, the use of the various electrical equipment of convenient control is not intended to contact metal the end of a thread or plug metal film if the people stands on the ground with hand, just can not take place to get an electric shock or beaten phenomenon, strengthen safety and reliability that household electrical appliance use by electric shock.
The utlity model has and beautify the environment, advantage such as fail safe is good.

Wherein, 1-ship shape socket, 2-fort shape plug, 3-helicopter shape plug, 4-chimney plug, 5-house shape plug, 6-are control switch, and 7-is a live wire, and 8-is a ground wire, and 9-is a zero line, and 10-is an electrode, and 11-is a fuse, and 12-is a gas discharge tube, the 13-pin
Embodiment
As Fig. 1, the supply socket of a kind of ship shape shown in Figure 2 is characterized in that: every group of jack of wiring board all has a branch position control switch 6.Described ship shape socket is provided with over-pressure safety device.Described fort shape plug 2, helicopter shape plug 3, chimney plug 4, house shape plug 5 can be movable plug.The pin l3 of described plug and the jack of wiring board match.The electrode 10 main good phosphor-copper materials of elasticity that adopt.The controlled function of control switch 6 realizes by such process, and firewire electrode is connected with control switch respectively, and the position of control switch correspondence is exposed on the live wire 7, by pushing control switch firewire electrode and live wire is connected, and forms current circuit.By independent control switch, can reliably control the break-make of power firestreak, need charged dangerous and trouble of pulling out, inserting plug when saving a plurality of electrical equipment and not using simultaneously, the use of the various electrical equipment of convenient control has strengthened safety and reliability that household electrical appliance use.
Over-pressure safety device is with between 12 parallel connections of a gas discharge tube and zero line 9 and the live wire 7; a fuse 11 is connected on gas discharge tube 12 front portions with live wire; in case there is overvoltage to appear at gas discharge tube 12 two ends; gas discharge tube 12 will change conducting state over to by state of insulation rapidly; effectively with the overvoltage shorted to earth; short circuit current blows a fuse, thereby has effectively protected electrical appliance.
The ship shape socket uses special high temperature resistant, high flame retardant, high-intensity engineering plastics manufacturing, has very high resistance to wear, resistance to impact and cold, moisture resistance and high insulation property, Danger Electric shock risk occurs in effectively preventing to use.
