The inner cavity of the housing is divided into an upper cavity and a lower cavity by a separator plate; the separator plate is provided with a wire hole; the power source module is fixedly installed in the lower cavity; the PCB, the USB jacks and the DC jack are all fixedly installed in the upper cavity; a corresponding interface in the power source module is connected with a corresponding interface in the PCB through a wire which passes through the wire hole; the corresponding interface in the PCB is connected with the USB jacks, and the DC jack is connected with a corresponding interface in the power source module through a wire which passes through the wire hole. When the double voltage portable power source is at work, the DC jack is directly connected with the power source module, the double voltage portable power source does not need to carry out voltage and current conversion through the PCB, and the double voltage portable power source with the DC jack is slight in electrical loss, high in charge and discharge efficiency and wide in application range.

Description

With two voltage portable power sources of DC jack

Technical field

The utility model relates to a kind of portable power source, specifically be a kind of charging of two voltages, electric discharge portable power source with DC jack.

Background technology

Portable power source, is a kind of portable charger that integrates power supply and charge function, can charge whenever and wherever possible or standby power supply to digital equipments such as mobile phones.Generally by lithium cell or dry cell as charge storage unit.Convenient to use.For the variation day by day of digital product function, use more frequent, how associated also more and more closer with our daily life, improve the service time of digital product, the life being convenient for people to, supplement electric weight in time, to bring into play the importance that its maximum work uses just more very urgent.And portable power source, exactly for and the preferred plan that addresses this problem, carry a portable power source, can be just multiple digital product charging whenever and wherever possible.

How existing portable power source, only have one or two USB interface and a Micro USB interface for charging.In actual use, use USB interface to power, although can meet the requirement of most digital product, but still some electronic product cannot use USB interface to power, or using USB interface to power can not match with itself and original power interface, and power supply energy loss after PCBA boosts, changes is larger.Meanwhile, as in actual use, when two USB interface on portable power source are simultaneously when supplying power for outside, the load that is subject to of the pcb board of Yin Putong is limit, and very easily causes overload, thereby causes portable power source seemingly-dead, cannot carry out electric energy output, the activation of need to charging.As improve pcb board, and can cause again the production cost of portable power source to increase, be unfavorable for the market competition of enterprise.On the other hand, the Micro USB interface that now portable power source uses, charge efficiency is extremely low, specifically, need to be longer time, rechargeable battery built-in portable power source could be full of.Can not meet the needs of modern's fast pace life.

Utility model content

The purpose of this utility model is to provide the portable power source of a kind of pair of voltage charging and discharging, and it not only can charge by Micro USB, the electric discharge of USB socket, the portable power source that also can directly be charged, be discharged by DC jack.

For achieving the above object, the technical scheme that the utility model adopts is: a kind of two voltage portable power sources with DC jack, it includes housing, power module, pcb board, USB socket, DC socket.

Described housing inner chamber body is divided into upper cavity, lower chamber by a dividing plate;

On described dividing plate, have wire guide;

Described power module Guan County is in lower chamber;

Described pcb board, USB socket, the equal Guan County of DC socket are in upper cavity;

Corresponding interface on described power module passes wire guide wire by warp is connected with corresponding interface on pcb board;

On described pcb board, corresponding interface is connected with USB socket;

Described DC socket is connected with the corresponding interface on power module by the wire passing through a wire guide;

In described housing outer surface, be also embedded with the LED illuminating lamp, control button and the battery capacity indication lamp that are connected with pcb board by wire respectively.

When the utility model work, direct-connected by DC socket and power module, need not carry out voltage, current conversion through pcb board, make electrical loss little, efficiency for charge-discharge is high, applied widely, USB socket can provide respectively different voltage for use from DC socket simultaneously, to meet more use needs, simultaneously in the time of charging, also can charge by DC socket and USB socket, realize two two putting of filling.
