Abstract
The utility model discloses a transformer with zero power consumption under the no-load condition. The transformer comprises a shell connected with a connection socket, and a transformation circuit, wherein an output power supply of the transformation circuit is output through the connection socket; and a switching device which is used for switching on an input power supply of the transformation circuit only when the connection socket is inserted is arranged on the connection socket. By the transformer, zero power consumption is completely realized under the no-load condition; the transformer is concise in design, low in cost and easily popularized and transformed; and due to the switching device, the transformer is high in reliability and environmental adaptability, a great help is provided for reduction of energy consumption and emission of carbon dioxide, and considerable economic and environmental benefits are gained.
Description
Technical field
The utility model relates to a kind of transformation device that can realize zero-power when zero load.
Background technology
The world today, reducing energy consumption is the only way of sustainable development.All there is no-load power consumption in a large amount of converting equipments in production or the life.Employed electric energy when no-load power consumption refers to converting equipment and load disconnection and do not carry out any function.As, be plugged on the charger for mobile phone on the wall socket, although do not link to each other with mobile phone, its inner power transformation circuit is in unloaded standby, so still can consume electric energy.ENERGY STAR 2.0 standards are carried out in the design of the power supply of present AC to DC and DC to DC, no-load power consumption.Reduce the progress that no-load power consumption relies on AC to DC PWM control IC technology, the standard of no-load power consumption progressively reduces from 0.45W, 0.5W, 0.3W, but with regard to present technology, still can not eliminate unloaded energy resource consumption fully.
Summary of the invention
The purpose of this utility model is to eliminate the problem of unloaded energy resource consumption fully in order to solve prior art, proposes a kind of power transformation device that can realize zero-power when zero load.
A kind of unloaded zero-power power transformation device that the utility model proposes comprises the housing and the power transformation circuit that are provided with gang socket.The out-put supply of this power transformation circuit also is provided with the switching device of just connecting described power transformation circuit input power when having attachment plug to insert through described gang socket output in this gang socket.
More excellent, switching device can comprise the push rod that is connected the plug promotion, fixed contact, and drawn stem drives the elasticity moving contact that contacts with fixed contact, and this elasticity moving contact resets push rod when inserting without attachment plug.
Wherein, push rod can be insulating material.
Described switching device can also be sensitive switch.
More excellent, gang socket can be USB socket.
The utility model can fast, thoroughly be realized not needing the energy of assisting by zero no-load power consumption by the passive mechanisms switch; Simple for structure, reliability is high, and cost is low, easily popularizes to transform; Environmental suitability is strong; Application is extensive.Present design has solved and has reduced no-load power consumption to the dependence of PWM master control scheme technology; Solved the different technologies level of each scheme to the dependence of application person's technical merit.To reducing energy consumption and reducing CO2 emission great help is arranged; Considerable economy, environmental benefit are arranged.

Embodiment
The utility model provides realizes the power transformation device of zero-power when unloaded, and it comprises with the housing of gang socket and power transformation circuit.The out-put supply of this power transformation circuit is through gang socket output, and gang socket is provided with switching device SW, the break-make of this switching device SW control power transformation circuit input power.When having attachment plug 4 to insert in the gang socket, utilize the mechanical trip that inserts, realize synchronously opening or closure of switching device SW.CN2 is gang socket, the normally opened contact string in the switching device SW on the power input line of power transformation circuit, the synchronization association of the insertion state of attachment plug and power transformation circuit ON/OFF.Thereby realize when the user does not insert attachment plug, turn-offing the power transformation circuit, converting equipment is quit work when the user does not use, thereby realize unloaded zero-power.
The gang socket of the present embodiment is USB socket 6.Switching device comprises: push rod 1, elasticity moving contact 2 and fixed contact 3.Referring to Fig. 1, USB socket 6 and switching device SW are contained on the pcb board, and the push rod 1 inside elasticity moving contact 2 that promotes contacts with fixed contact 3 when having attachment plug 4 to insert among the gang socket USB; Referring to Fig. 2, when attachment plug 4 was extracted, under the elastic reaction of elasticity moving contact 2, push rod 1 resetted.
As shown in Figure 1 and Figure 2, a kind of non-isolated switching device.In another was implemented, switching device adopted isolated, and its push rod 1 is insulating material, and push rod 1 is longer, passes the isolation strip, realized the switch control to dangerous voltage.In addition a kind of substitute mode can be arranged, namely switching device is sensitive switch, and this sensitive switch is triggered when having attachment plug 4 to insert in the gang socket, just connects power transformation circuit input power.
Only in order to illustrate structure of the present utility model, those of ordinary skill in the art can make various deformation and variation to above specific embodiment under design of the present utility model, and these distortion and variation include within protection range of the present utility model.
