Abstract
The utility model relates to a USB charger in a mahjong machine. The USB charger is connected with a 220V alternating-current voltage. The USB charger is characterized in that the USB charger comprises an alternating-current transformer, a rectifier bridge, an direct-current transformer chip, a filter and a USB interface, wherein the alternating-current transformer, the rectifier bridge and the direct-current transformer chip are connected successively, and the direct-current transformer chip is connected with the USB interface through the filter. The USB charger has the following advantages: mobile terminals, such as a mobile phone, a MP3, etc., of a user can be charged while the use is in entertainment, so the mobile terminals of the user will not be separated from the user, so that the user can perform external real-time communication and does not need to worry that the terminals are stolen.
Description
Technical field
The utility model relates to mahjong machine, relates in particular to the USB charger in a kind of mahjong machine.
Background technology
Mahjong machine is that relatively more universal at present recreational facilities are arranged in all kinds of chess and card rooms widely.Have in the hobby person of mah-jong pieces and like greatly the amusement in chess and card room with the gambler, the mobile terminals such as mobile phone, MP3 that often have the entertainer when carrying out amusement need charging, needs due to safety and real-time communication, can not be away from the entertainer during cell-phone charging, preferably can be implemented on mahjong machine, but existing mahjong machine does not have such function.
Summary of the invention
The utility model purpose is to overcome the deficiency of above prior art, and providing a kind of need to the USB charger of cell-phone charging, specifically have following technical scheme to realize when the mahjong in-flight entertainment:
USB charger in described mahjong machine, be connected with the 220V alternating voltage, comprise AC transformer, rectifier bridge, the direct current transformation chip, filter and USB joint, described AC transformer, rectifier bridge and direct current transformation chip connect in turn, and the direct current transformation chip is connected with described USB interface by filter.
The further design of the USB charger in described mahjong machine is, described filter is by inductance coil and electric capacity and connect and form.
The further design of the USB charger in described mahjong machine is, described direct current transformation chip is XL1410.
The further design of the USB charger in described mahjong machine is, described USB joint is provided with four contacts, and described contact comprises a cathode contact, and the direct current transformation chip has two outputs of high electronegative potential.
The further design of the USB charger in described mahjong machine is, the output of direct current transformation chip high potential is connected with the cathode contact of USB, and the electronegative potential output is connected with other contacts of USB joint respectively.
Advantage of the present utility model is as follows:
Facilitate the entertainer in amusement, to mobile phone, the mobile terminals such as MP3 charge, and avoid entertainer and mobile terminal to separate, can with extraneous real-time communication, do not worry that terminal is stolen yet.
Description of drawings
Fig. 1 is the structural representation of described tight sleeve optic cable.
Embodiment
Below in conjunction with accompanying drawing, the utility model scheme is elaborated.
Contrast Fig. 1, USB charger in the mahjong machine that the present embodiment provides, be connected with the 220V alternating voltage, comprise AC transformer, rectifier bridge, direct current transformation chip, filter and USB joint, AC transformer, rectifier bridge and direct current transformation chip connect in turn, and the direct current transformation chip is connected with USB interface by filter.Filter is by inductance coil and electric capacity and connect and form.The USB joint is respectively equipped with four contacts of 1-4, and wherein contact 4 is cathode contact.The direct current transformation chip that the present embodiment adopts is XL1410, be that 8 pin chip pins 2 are connected with rectifier bridge, this XL1410 chip also comprises two outputs of high electronegative potential, 3 high potential outputs of pin are connected with USB tip side cathode contact, and 5 electronegative potential outputs of pin are connected with the 1-3 contact of USB joint respectively.
220V voltage is reduced to 12 alternating voltages through AC transformer, then forms 12 direct voltages through rectifier bridge, then is that XL1410 is down to the 5V direct voltage with 12V through the direct current transformation chip, thereby the standard that reaches the mobile terminal charging inlet facilitates the entertainer to use.
