Description

A kind of USB charger with pin adaptor

Technical field

The utility model relates to plugs and sockets switch technology and charger technology, relates to a kind of USB charger with pin adaptor particularly.

Background technology

At present, people's living standard improves constantly, and all there are the different mobile phones of multi-section in most of family, and universal charger emerges and makes different mobile phones use the dream of same charger to realize.Yet the defective that the universal charger ubiquity charging interval is long, and need battery of mobile phone to take out during charging, this moment as do not have the words mobile phone of reserve battery just can not use for a long time.Can't satisfy people's life requirement at universal charger, country has issued up-to-date communication industry standard: YD/T1591-2006, and this standard is divided into two separate components with mobile phone and charger for mobile phone, and both connect with connecting line.Regulation is connected to charger in the standard plug and charger socket are all used USBA series, thereby the type charger abbreviation USB charger.Fast, highly versatile of USB charging interval is except that can therefore adopting the charger of USB charging inlet to use more and more general to also charging to most of digital products such as MP3, MP4, digital cameras the mobile phone quick charge.

Existing USB charger comprises Charger (portable round), USB charging circuit board and USB output interface, charger is inserted the general two pin input plugs that adopt, arrive the different regions of country variant or same country as people, all very likely meet difform supply socket, at this moment existing USB charger possibly can't cooperate socket and can not use.USB charger itself takies jack interface simultaneously, even appropriate receptacles is arranged but too much because of power consumption equipment, other power consumption equipment just can not use after charger took socket.

Summary of the invention

The utility model is for solving the inconvenience of above-mentioned existing USB charger in application, and a kind of USB charger of practical band pin adaptor is provided.

The utility model is achieved through the following technical solutions goal of the invention, a kind of USB charger with pin adaptor, comprise Charger (portable round), USB charging circuit board and USB output interface, described charger also comprises pin adaptor, the plug of USB charger inserts in the accessory power outlet of pin adaptor, and the USB charger is fixedlyed connected with pin adaptor by the elasticity retention mechanism.

Described pin adaptor comprises primary input plug and auxiliary plug, and auxiliary plug is arranged in the pin adaptor sidepiece groove, and the shell of auxiliary plug is actively plugged in the pin adaptor groove.

Described primary input plug is English rule plugs, and auxiliary plug is an Europe rule plug.

Described pin adaptor housing main body bottom is provided with the standby safety box of externally positioned type, and rewirable fuse is housed in the box.

Described USB charger top is provided with accessory power outlet.

Described USB charger bottom is provided with the externally positioned type safety box, and rewirable fuse is housed in the box, and fuse is electrically connected with the pin adaptor internal circuit.

Two pins of described USB Charger (portable round) can rotate into certain Angle around central axis separately.

Described elasticity retention mechanism comprises that elasticity connecting plate, pine unload button and screens projection, pine is unloaded on the shell that button is symmetricly set in pin adaptor, pine is unloaded button and fixedlys connected with the elasticity connecting plate, and the screens projection is arranged on the pin adaptor and with corresponding groove on the USB charger and is connected.

In the utility model, circuit is by pin adaptor plug incoming transport power supply, through safeties, the one road is connected to the USB Charger (portable round) and by USB charger socket out-put supply then; Other one the road inserts the USB charging circuit board, through step-down module and voltage stabilizing circuit output constant voltage, is connected to the USB output interface through current-limiting control circuit again, and the operating state of voltage stabilizing circuit and current-limiting control circuit can be come out by the led function indicated number.

USB charger and pin adaptor flexibly connect, separately use separately detachable back, use also capable of being combined is used with the USB charger respectively after main plug in the pin adaptor and auxiliary plug can be dismantled simultaneously, also can combine with the USB charger and use simultaneously.

The beneficial effects of the utility model are, and are simple in structure, easily manufactured, just can realize 4 kinds of plug shapes by simple conversion; Applied widely, the charger input voltage range can both normally be used at 90-260VAC, is suitable for the line voltage and the jack type of the most of country in the whole world; Product has multipurpose, and is practical, and itself can be used as supply socket charger.
