Abstract
The utility model relates to a patch panel, particularly to a safety power supply patch panel which is used to prevent electric shock and automatically switch off the power supply. The safety power supply patch panel comprises a socket and fuses, and is characterized in that a residual current circuit breaker, a photoelectric infrared switch and a timing switch which are connected in series are connected between the socket and the fuses. The residual current circuit breaker, the photoelectric infrared switch and the timing switch are installed on the patch panel, so the safety power supply patch panel can automatically switch off the power supply when electric leakage occurs to domestic. If the power supply of some high power electric appliances isn't switched off in time when people leaves, the safety power supply patch panel can also automatically switch off the power supply. The utility model has simple structure and has the functions of safety and energy saving.
Description
Technical field
The utility model relates to a kind of power board, relates in particular to a kind of safety power supply power board that is used to prevent to get an electric shock and cuts off the electricity supply automatically.
Background technology:
At present, the power supply power board that people use, long-term energising, general do not have prevent to get an electric shock, cut off the electricity supply automatically and the function of timing cutting power, tend to sometimes cause that because of the household electrical appliance electric leakage electric shock injures and deaths or some powerful electrical appliances are because forgotten in time to turn off the fire incident that power supply causes.
The utility model content
Have defective for overcoming prior art, the utility model provides a kind of not only safety but also energy-conservation safety power supply power board.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of safety power supply power board, comprise socket, and fuse is characterized in, connects residual current circuit breaker, Photoelectric infrared switch, the timing switch of series connection between socket and the fuse.
The beneficial effects of the utility model are to adopt the power supply power board of this structure, residual current circuit breaker, Photoelectric infrared switch, timing switch have been installed on power board, when taking place, the household electrical appliance electric leakage can cut off the electricity supply automatically, when some powerful electrical appliances when the people leaves away, can cut off the electricity supply automatically when having forgotten in time to turn off power supply, simple in structure, played safety and energy-conservation effect.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment
Shown in Figure 1, a kind of safety power supply power board comprises socket CZ, and fuse R is characterized in, connects residual current circuit breaker LJ, Photoelectric infrared switch HJ, the timing switch DJ of series connection between socket and the fuse.
When the electrical appliance in the socket leaked electricity, residual current circuit breaker contact LJ disconnected, and when the people left, contact HJ disconnected through the suitable time-delay Photoelectric infrared switch, can also set timing switch DJ contact and disconnect in 1～120 minute as required.When the household electrical appliance electric leakage takes place, can cut off the electricity supply automatically, when some powerful electrical appliances when the people leaves away, can cut off the electricity supply automatically when having forgotten in time to turn off power supply, simple in structure, played safety and energy-conservation effect.
Claims (1)
1. a safety power supply power board comprises socket (CZ), and fuse (R) is characterized in that, is in series with residual current circuit breaker (LJ), Photoelectric infrared switch (HJ), timing switch (DJ) between described socket and the fuse successively.
