As shown in Figure 1, comparison type power supply hookup mechanism of the present invention comprises: current transformer T1, and it has primary coil winding and secondary coil winding, and an end of primary coil winding is connected with basic load socket AC2; Current limit circuit breaker S1, the one end is connected with the other end of primary coil winding, is used to bear scheduled current, and when electric current surpassed described predetermined current value, tripping automatically then can recover conducting automatically after the recovery predetermined current value; Current limit circuit breaker S2, the one end is connected with the other end of circuit breaker S1, and its other end is connected with supply socket AC1, is used to bear the electric current higher than circuit breaker S1, and when electric current surpasses described current value, then tripping automatically, but can manually make it recover normal; Current value selector S3, can by change current transformer T1 secondary coil winding the number of effective coils, adjust the induced current size; Bridge rectifier D 2, it is parallel with commutation condenser C2 and Zener diode (limiter diode) D1, and be connected with contact DIN1, the DIN2 of the secondary coil winding of current transformer T1, be used for converting alternating current to direct current and stably control voltage after rectification; Relay U1 is connected to bridge rectifier D 2 in it, the direct voltage by rectifier D2 is driven, and to produce the function of switch, that is, cuts off automatically when the undertension of rectifier D2; Surge absorber C1 prevents the surging from external power source; And a plurality of external socket A3～A8 in parallel, being used to connect a plurality of electric equipments, these a plurality of external socket one ends in parallel are connected with the ACIN A end of supply socket AC1, and the other end then is connected with the AC IN C end of following relay U1.
The end AC IN C of relay U1 is connected with the AC IN C of socket A3～A8 end, and other end AC IN D and circuit breaker S1, S2 connect altogether.
What emphasize in this embodiment is, the size of current of the primary coil winding by flowing through current transformer T1 is carried out control operation, rather than general traditional voltage that passes through transformer is controlled.In circuit of the present invention, be provided with current limit circuit breaker S1, S2 safeguard measure is provided.For example in the designed example of this embodiment, the current settings of baseplug AC2 is lower than below the default maximum 2A of circuit breaker S1, to keep the normal operation of electric equipment; When the electric current by baseplug surpassed the default maximum 10A of the default maximum 2A of circuit breaker S1 or even circuit breaker S2, current limit circuit breaker S2 will cut off automatically, is not burnt with the protection electric equipment.
In order to help, describe again in this characteristic with regard to the known current transformer that the present invention utilized to understanding of the present invention.General current transformer all is to be serially connected in the circuit loop, and the copper cash of elementary winding is thick and the number of turns is less, and the copper cash of secondary winding is thin and the number of turns is more, and both number of turns have very big multiple poor, and major function is that the big current conversion that flows into is become little electric current.Therefore, this current transformer can carry out elasticity according to behaviour in service and switch again by a current value configuration switch S3.For example, this switch S 3 has three sections handoff functionalities, when required electric current is big, then switches to the 1st section, and required electric current hour then switches to the 3rd section, so can reach a kind of adjustment mode of power saving.
Fig. 2 is assembled into the stereoscopic figure of a kind of material object that prolongs line style for representing power supply connected circuit device of the present invention, and wherein the member symbol is corresponding to the symbol of the defined function assembly in Fig. 1 circuit diagram, and it has the function that is equal to.Fig. 3 becomes the exploded perspective view that prolongs line style for each component groups of the present invention shown in Figure 2 is contained in the shell.The main purpose of the stereogram of Fig. 3 is to show that a plurality of socket A3～A8 are when actual assembled and the position in the space between shell relation, as for other circuit unit among Fig. 2, be after concentrating on distributing board 7 in known manner, be fixed on the intermediate plate 5, the problem of this design freedom is not further described.Wherein, shell comprises a shell 4 and a lower casing 6 on one, utilizes known mode such as screw 15 to connect and constitutes an inner space to hold power supply hookup mechanism of the present invention together.Switch S 2, socket AC2 are installed in upper surface at last shell 4, and in the neighboring selector S3 are installed, but their positions on last shell 4 are not specific, can elect according to the convenience of using.As for most socket A3～A8 of parallel connection, as shown in the figure, respectively pass through a lead B3～B8 from last shell 4 or lower casing 6, part is at last shell, and part is carried out the extension of certain-length in the mode of lower casing or intermediate plate 5 positions.But the position elasticity between each socket A3～A8 changes, and adapts to the electrical equipment of outside different size, so just can not interfere with each other and can not peg graft.This is arranged on the shell intact different with conventional socket in a fixed manner.For example, because present many products are considered the factor of volume production, and independent outside power supply unit, replace by transformer.The extended line jack that utilizes this quasi-tradition because transformer is bulky, squeezes simultaneously in the inconvenience that can cause on the extended line in the use, even can use adapter when using transformer, has reduced the convenience of using widely and has increased danger.But in the present invention, adopted this kind lead external socket, in practical application, can well be used with transformer, because it is there is external connection to cushion, also comparatively well-to-do on usage space.
For example using a computer and using the present invention during interface equipment; at first plug AC1 is inserted the socket that power supply can be provided; and make switch S 2 conductings that expose with manual mode; when the master computer (not shown) power-on that is connected with socket AC2, electric current begins to flow through and one prevents the surge absorber C1 of surging injury and have the switch S 1 of defencive function and arrive current transformer T1.In the present embodiment, earlier current value configuration switch S3 is transferred to for example the 1st section, to meet the power consumption of a master computer.At this moment, secondary two contact DIN1, the DIN2 of current transformer T1 are connected respectively to bridge rectifier D 2, and, will be rectified into for example direct current of 12V (DC) from the alternating current (AC) of socket AC1, to keep the running of relay U1 by Zener diode D1 and commutation condenser C2.
By the effect of relay U1, can make AC IN B become conducting state with AC IN C, a plurality of socket AC3～AC8 therefore in parallel also conduct electricity, and can be to each electric power supply that is connected in accordingly on a plurality of socket AC3～AC8.
Otherwise when master computer cut out, the electric current that flows into current transformer T1 primary coil winding diminished, the voltage drop of secondary coil winding is low to moderate below the operating voltage of relay U1, thereby relay becomes to open circuit, and causing at the AC of relay U1 IN C end does not have electric current, so also no current of each socket A3～A8.Thereby the electrical equipment that is connected socket A3～A8 can consumption of electric power yet, thereby reaches the purpose that the present invention saves electric energy.
