Embodiment

Through following specific embodiment, specify the utility model with reference to accompanying drawing.

Extremely shown in Figure 3 like Fig. 1; Be a kind of improved power socket board of the utility model; Have an attaching plug 10, an electric wire 1 and a socket group 2; Socket group 2 comprises the housing of an insulation, wherein, comprises at least one AC Power supply socket 21 and at least one Direct current power source socket 22 that parallel connection is provided with in the housing; And each DC power supply is beaten and is provided with a control circuit between seat 22 and power supply, and this control circuit contains a transforming circuit 31, a rectification circuit 32, one (direct current) filter circuit 33, one (direct current) voltage stabilizing circuit 34 then through an output circuit 35 outputs; Wherein, transforming circuit 31 is changed the voltage of civil power, and rectification circuit 32 changes into direct current with interchange, and the noise that filter circuit 33 is eliminated electric currents also forms all-wave output, and voltage stabilizing circuit 34 lets voltage and current stabilization ground export.Being two rows' supply socket among Fig. 1, is respectively two AC Power supply sockets 21 of leading portion and a Direct current power source socket 22 of back segment; Show first to fourth direct current or AC

Power supply socket

22 or 21 in the calcspar of Fig. 3 respectively, that is to say the meaning that can be provided with more than to the supply socket of proper number.

Control circuit also can comprise a display circuit 36 (shown in Figure 3); Also can be provided with the voltage-selected switch of civil power input, because civil power has 110V and two kinds of main specifications of 220V, but not as limit, if having one to select and set adjustment, more safely use lets the more stable operation of transformer in the transforming circuit 31; Transforming circuit 31 wherein can be switched power supplier (shown in Figure 2).

In circuit diagram, demonstrate the bridge rectifier of rectification circuit 32 for forming by four diodes; It act as the interchange input is changed into direct current output effectively, and this has been the circuit mode of habitually practising, and its thin portion no longer explains; Certainly also can be other rectifier system, to form direct current output.

Transforming circuit 31 in Fig. 2 is a switched power supplier; It is to be located at a utmost point that connects the transformer primary side behind the bridge rectifier; Transforming circuit also contains a high frequency voltage descending transformer in other words; Circuit Fault on Secondary Transformer one extremely after after direct current rectification and the filtering; And with another of Circuit Fault on Secondary Transformer extremely after behind the direct current current-limiting, regular and protection, through another utmost point of the primary side of photo coupler, positive feedback circuit, amplification and oscillating circuit to transformer, it also accomplishes the function of transformation and rectification again.
