Abstract

The utility model relates to an expanding power wire of a power load, which can be used between power supplies in various electric appliances and the built-in devices thereof; wherein the power wire is connected in parallel with at least one charge / discharge component. The utility model can be used as a buffer of the built-in voltage and current according to different load requirements in the condition that the specification and design of the power supply are not changed, so as to avoid unstable instant voltage and current supplying or instability or damage of the functions of the built-in devices caused by too large instant power.

Description

Power source loads expands power line

Technical field

The utility model relates to the design that a kind of power line load is expanded, and refers to that especially a kind of power source loads of doing the electric current and voltage buffering between power supply unit and built-in device expands power line.

Background technology

In scientific and technological flourishing epoch now, there are many sci-tech product functions to do more powerful and more powerful, so relative also just many more of The built-in device, and the power supply unit of general electrical equipment inside all can count the built-in device that connects in advance when design, and once after this power supply unit batch process, just can not go to change former design again, because just small at last increase and decrease specification all need be changed former design again, and change intrinsic formality and time, all will cause the loss of manufacturer on cost.

Figure 1 shows that known electrical equipment internal electric source supply and built-in schematic representation of apparatus, this electrical equipment 1 inside is provided with a power supply unit 11, this power supply unit 11 is obtained stable power by the power line 111 of external civil power, and before output is used for built-in device 12, can be earlier within it portion's transformation be rectified into the required electric current and voltage of built-in device 12, power through the power line 121 of 12 in power supply unit 11 and built-in device again.

And three built-in devices 12 of the inner only default installation of tool originally; as VCD; MP3; DVD etc.; if after this electrical equipment 1 enters batch process; catch sight of and to issue additional a built-in device 12 again; its function multiplication is strengthened under the situation of the market competitiveness; the make use of momentum design and the specification (outfit) of the original power supply unit 11 of necessary change; and the power supply unit 11 of former specification is when increasing power supply again and giving another built-in device 12; can cause the supply of transient voltage electric current unstable unavoidably; make the unstable even jumping of power supply unit 11 functions of electrical equipment 1; cause built-in device 12 runnings of electrical equipment 1 not normal; or damage because of improper outage; perhaps, under many low power built-in devices 12 use, open a powerful built-in device 12 again; this moment high-power; this power supply unit that more renews 11 also might cause and use the undesired or damage of low power built-in device 12 work, if can cause cost significantly to improve again.

The utility model content

The main technical problems to be solved in the utility model, be a kind of power source loads of design and expand power line, do not change at power supply unit under the situation of specification and design, can be according to the buffering of the different demands of load as the electric current and voltage of built-in device, avoid causing the supply of transient voltage electric current unstable, or because of power moment of using excessive, and cause the unstable or damage of built-in apparatus function.

In order to achieve the above object, the utility model is achieved in that a kind of power source loads expands power line, is electrically connected between various electrical equipment internal electric source supply and the built-in device.Wherein, be parallel with a charge/discharge assembly on this power line at least; Above-mentioned power source loads expands power line, and this charge/discharge assembly can be electric capacity; Above-mentioned power source loads expands power line, and this charge/discharge assembly also can be formed by inductance and electric capacity series/parallel.

As from the foregoing, the utility model can not change under the situation of specification and design at power supply unit, according to the buffering of the different demands of load as the electric current and voltage of built-in device, avoid causing the supply of transient voltage electric current unstable, or excessive because of the instantaneous power of using, and cause the unstable or damage of built-in apparatus function.

Description of drawings

Fig. 1 is known electrical equipment internal electric source supply and built-in schematic representation of apparatus.

Fig. 2 expands the organigram one of power line for the utility model power source loads.

Embodiment

For making the purpose of this utility model, feature and effect more obvious, by following specific embodiment, and conjunction with figs., the utility model is described in detail.

Fig. 2,3 and 4 is respectively organigram one, two and the preferred embodiment figure thereof that the utility model power source loads expands power line.Shown in Fig. 2,3 and 4, this electrical equipment 1 inside is provided with a power supply unit 11, this power supply unit 11 is obtained stable power by the power line 111 of external civil power, and before output is used for built-in device 12, earlier portion's transformation is rectified into the required electric current and voltage of built-in device 12 within it, powers through the expansion power line 2 of 12 in power supply unit 11 and built-in device again; Wherein, this expansion power line 2 is applied between various electrical equipment 1 internal electric source supply 11 and the built-in device 12, expanding on the power line 2, have once series connection one inductance 22 electric capacity in parallel again 21 formed charge/discharge assemblies (as shown in Figure 2), the electric capacity 21 of also available two parallel connections constitutes a charge/discharge assembly (as shown in Figure 3).

Whereby, when script power supply unit 11 inner only default three built-in devices 12 of installing, as VCD, MP3, DVD etc., if after this electrical equipment 1 enters batch process, catch sight of and to set up a built-in device 12 again, its function multiplication is strengthened under the situation of the market competitiveness, when increasing power supply again and giving another built-in device 12, only need to change expansion power line 2 of the present utility model, can make power supply unit 11 under the situation that does not change specification and design, can do the buffering of electric current and voltage according to the different demands of the load of built-in device 12, avoid causing the supply of transient voltage electric current unstable, or because of power moment of using excessive, and cause built-in device 12 function shakiness or wasters.

In sum, the power supply of the more known electrical equipment internal electric source of structure of the present utility model is configured with innovation, has progressive, and tool practicality and value.

Though the utility model with above-mentioned preferred embodiment openly as above, is not in order to limit the scope that the utility model is implemented.Any those who familiarize themselves with the technology, in not breaking away from spirit and scope of the present utility model, when doing a little change and modification, all equalizations of doing according to the utility model change and modify, should be the utility model claim and contain, it defines and should be as the criterion with claims.
