Embodiment
Below enumerate specific embodiment describing the content of this creation in detail, and with diagram as aid illustration.The symbol of mentioning in the explanation is with reference to legend.
Please refer to shown in Figure 1ly, is the electricity-saving system schematic diagram that proposes for this creation.The power saving system that this creation proposes is to comprise an electricity saver 10 and an electronic installation 20.Electricity saver 10 comprises modular converter 101 and lead-out terminal 103.Electricity saver 10 is electrically connected a civil power 30, in order to receiving the alternating current that civil power 30 provides, and sees through modular converter 101 alternating current is converted to direct current, then via lead-out terminal 103 outputs.Electronic installation 20 comprises input terminal 203, is the lead-out terminal 103 in order to connection electricity saver 10, and then accepts the direct current that electricity saver 10 provides.
In this, electricity saver 10 has described mode of operation of prior art and battery saving mode.Electronic installation 20 can be the electronic installation that mobile phone, GPS navigation machine etc. have rechargeable battery, provides electric power to give the usefulness that electronic installation charges by electricity saver 10.Lead-out terminal 103 and input terminal 203 can be the USB splicing ear, but this creation is not as limit.
Please refer to shown in Figure 2ly, be the first terminal circuit diagram of this creation.Aforementioned input terminal 203 can be the first terminal circuit 40, comprises the first voltage pin position 401, the first grounding leg position 403 and first shell 405.First shell, the 405 ccontaining first voltage pin position 401 and the first grounding leg positions 403, and first shell 405 is electrically connected the first grounding leg position 403.
Please refer to shown in Figure 3ly, be the second terminal circuit diagram of this creation.Aforementioned lead-out terminal 103 can be the second terminal circuit 50, is to comprise the second voltage pin position 501, the second grounding leg position 503, second shell 505 and resistance 507.When lead-out terminal 103 connected input terminal 203, the second voltage pin position 501 was electrically connected the first voltage pin position 401, in order to transmit the accurate position of galvanic power supply; The second grounding leg position 503 is electrically connected the first grounding leg position 403, in order to transmit the accurate position of galvanic ground connection.Second shell, the 505 ccontaining second voltage pin position 501 and the second grounding leg positions 503, and be electrically connected with first shell 405.Resistance 507 is electrically connected between the second voltage pin position 501 and second shell 505.
Therefore, when lead-out terminal 103 connects input terminal 203, second shell 505 is electrically connected first shell 405, first shell 405 is electrically connected with the first grounding leg position 403 and the second grounding leg position 503, the link that makes 505 on the resistance 507 and second shell is the accurate position of ground connection, causes resistance 507 to act on accurate position of power supply and the accurate interdigit of ground connection.In this, though the internal resistance of cell of electronic installation 20 rises with charging process, so keep certain loads because of resistance 507, make the electric current of electricity saver 10 outputs can not be lower than the described threshold current of prior art, therefore, be full of until battery electric quantity, electricity saver 10 still can not enter battery saving mode, can solve the problem that battery electric quantity can't be full of.
On the other hand, when lead-out terminal 103 did not connect input terminal 203, the link that the resistance 507 and second shell are 505 was a suspension joint, so lead-out terminal is considered as do not have connecting load, made electricity saver enter battery saving mode, can reach purpose of energy saving.
By above-mentioned, resistance 507 can be arranged at lead-out terminal 103, at this another embodiment that proposes this creation, resistance 507 is set in input terminal 203.That is lead-out terminal 103 can be the first terminal circuit 40; Input terminal 203 can be the second terminal circuit 50.Its start as described above, in this no longer repeat specification.In this, when lead-out terminal 103 did not connect input terminal 203, the second grounding leg position 503 can not be connected to the first grounding leg position 403 naturally, and therefore, resistance 507 is not limited only to be connected to second shell 505, and it also can be connected to the second grounding leg position 503.
Whether in this, electricity saver 10 can comprise a light-emitting diode (LED), electrically connect in order to show electricity saver 10 and electronic installation 20, as lighting when connecting.Also can make the light-emitting diode of the double-colored demonstration of apparatus, as bright green glow when connecting, azarin light during separation.
As described in prior art, electricity saver 10 can reduce the power source conversion frequency in battery saving mode, makes the dc voltage of conversion become the ripple shape cycle to change.Electricity saver 10 more can comprise cycle adjusting unit, in order to adjust the galvanic change in voltage cycle, the setting that averages out by this between energy-conservation and efficient.
In sum, when electricity saver 10 connects electronic installations 20, can be effectively the battery electric quantity of electronic installation 20 be full of; When not connecting electronic installation 20, less electricity consumption is reached in power saving design that can utilization itself.In addition, even charge,, so can not be lower than threshold current, and still battery electric quantity can be full of because of resistance 507 makes the electric current of electricity saver 10 outputs though its internal resistance of cell is inequality at different electronic installations.
Though the technology contents of this creation discloses as above with preferred embodiment; so it is not in order to limit this creation; anyly be familiar with this technical staff; do not breaking away from the spirit a little change and the retouching done of this creation; all should be covered by in the category of this creation, so the protection range of this creation is when being as the criterion according to the content that claim defined.
