Affiliated technical field

The utility model relates to a kind of power socket board (also claiming the power plug plate) that a supply socket is converted to a plurality of sockets commonly used, and especially each socket all has the power socket board of switch and indicator light.

Background technology

At present, no matter be at production units such as family, office, laboratory or factory, workshops, all be unable to do without and use power socket board.People's preference has the indicator light that display power supply is connected, and especially each shunt socket all has the indicator light of switch and display power supply connection.This be because, much more more and more electrical equipment is arranged, not charged source switch itself, as recorder, video tape recorder, VCD, DVD, battery charger, electric cooker, microwave oven, electromagnetic oven, bread producing machine, or the like.They are connected on the power supply will consume standby power.If there is not switch on the power socket board, to cut off the electricity supply so, have only from socket the plug of electrical equipment is pulled up.This is very inconvenient.

Usually, each shunt socket all has the power socket board of switch and indicator light, connects different electrical equipment regularly on socket along separate routes at each, controls switching on or off of they with switch.The indicator light of the demonstration energized of current employing mostly uses redness or green LED (LED) as indicator light.The color of the indicator light of each shunt socket switch all is the same basically.Which electrical equipment the electrical equipment that reminds people is connected is on earth, is difficult for producing effect significantly directly perceived.This power socket board once is in fashion after a while on market, but has reduced much on the market now.Tracing it to its cause, mainly is because the drive circuit of the LED that they use is too simple, very low of the efficient of circuit.The used electrical power overwhelming majority of drive circuit has all become heat and has dissipated.So not only user's usage charges will increase, and valuable electric energy is wasted.More fatal problem is because heater element constantly toasts the plastics of near switch and shunt socket, to make the plastics quick aging, become fragile.Thereby switch is damaged, and the electrode of socket comes off, and the life-span of power socket board itself becomes very short like this.Unless the good heat resistant plastice of service quality, just and to there be high mechanical strength to address this problem.So, manufacturing cost will improve a lot.

Summary of the invention

In order to overcome existing a plurality of sockets that have, each shunt socket all has high power consumption, the low life-span of the power socket board of switch and LED light and is difficult for the deficiency of which electrical equipment of identification connection directly perceived, the utility model provides a kind of power socket board, this socket can not only show that the power supply of which shunt socket has been switched on, and for each shunt socket different separately colors is arranged as the LED of indicator light.So, not only reminded the power supply of which electrical equipment of user to be switched on intuitively, and given the sensation of a kind of U.S. of people, especially when a plurality of sockets are connected simultaneously.

For the high power consumption of power socket board and the problem in low life-span, the utility model provides new led drive circuit, though this drive circuit than original circuit complexity a bit, but it is little that it still has a volume, characteristics in light weight, that price is low can be used on power socket board easily.

The technical scheme that its technical problem that solves the utility model adopts is: this have a plurality of sockets, little power consumption power socket board that switch and colored indicator light respectively arranged is electrically connected in certain sequence by the little power consumption drive circuit and the shell of 3 n pin package ns, lead, switch, supply socket, light-emitting diode, light-emitting diode, is assembled with shell again.Be connected to 3 leads on 3 n pin package ns, they are respectively live wire L, center line N and ground wire E.Wherein center line N and ground wire E separately directly with each socket on middle line jack be connected with ground wire jack; Live wire L enters after through a fusible link (F), receives each firewire jack on socket along separate routes through each branch switch; LED and drive circuit thereof that display power supply is connected are connected on the live wire of center line and fusible link back; Show that LED and drive circuit thereof that whether each shunt socket is connected are connected on the live wire and middle line jack of each shunt socket.Adopt the high brightness color LED as indicator light.Nowadays LED has had very fast development, and its color has had shades of colours such as red, orange, yellow, green, blue, white, adds the less Neutral colour of difference, is enough to make each socket of a power socket board to use different separately colors.And the LED of high brightness reduces the desired electric current of indicator light itself.Simultaneously, the drive circuit of LED adopts the drive circuit of newly developing, and they use capacitor and diode as circuit element, avoid using resistance as far as possible.Even in the time of will using resistance in case of necessity, this ohmically power consumption also is very low.Capacitor does not consume active power basically in circuit, the power consumption on the diode is again very little.Drive circuit is connected on the electrical network, and is only beneficial to electrical network because it is a capacitive load, do not have harm.So the efficient of this drive circuit is very high, the electrical power of consumption is descended significantly.They do not generate heat basically, can not influence the intensity of plastics because drive circuit heating, thereby cause the shortcoming that reduces greatly in useful life of power socket board.

The beneficial effects of the utility model are, when fully having kept each along separate routes socket has the major advantage of power socket board of switch and indicator light, have greatly reduced the electric power consumption of itself, have prolonged its useful life widely; Each along separate routes socket be connected and fixed electrical equipment the time, what remind easily that the user connecting now is that electrical equipment; When each indicator light was all lighted, it is beautiful more that power socket board can seem.
