Description of the Invention: [Technical Field] The present invention relates to a battery charger, and more particularly to a battery plug having a USB plug and axially coupling a USB plug and a charging control circuit board in a general body for charging battery capacity The charging slot is in a linear axial configuration with the housing to form a thin, long-loaded charger. [Prior Art] According to the popularization of portable electronic products such as digital cameras, MP3s, and PDAs, the demand for secondary batteries has also increased. However, the frequent problems with such electronic products using secondary batteries are When going out, if the battery is exhausted, there is a disadvantage of inconvenient charging. As shown in the first figure (A), a perspective view of a secondary battery charger is used. The first figure (B) is a side view thereof, and the bottom of the charger (1〇) is provided with a plug-in The plug of the AC power source (11) has a charging electronic component (12) therein and the positive and negative charging terminals (121) and (122) are exposed on the front and rear walls of the charging slot (13), thereby charging the battery (2) 〇) Charging. However, this kind of conventional charger (10) is connected to the socket of AC power supply with plug (11) (not shown), so it needs to have eight (^ turn Dc converter (14), and then The converter (14) supplies the required DC voltage to the charging electronic component (12). Therefore, the converter (14) occupies the space of the first half of the entire charger (10), and the charging electronic component (12) is set to be charged. The bottom of the slot (13); thus, the volume of the overall structure of the charger (10) is not easily reduced, which is inconvenient to carry out when carrying out; further, the plug (1 1) needs to be supplied with a charging power source by the AC socket, so, for example, It is not easy to find the AC outlet when going out. It is also a kind of missing. 1305697 times, as shown in the second figure, it reveals a conventional USB charger (3〇), which is connected by a charger body (31). (32) and USB plug (33), when going out, you can use an electronic product (40) with a USB socket (41) such as a computer for the USB plug (33) to be connected, to the charger body (31) Charging the battery (2〇) on the battery; this design is better than the AC shown in the first figure (A), (B) The appliance (10) has the advantage of being directly chargeable with the Dc power supply, but the internal architecture of the charger (30) still uses the AC charger (10), the difference is only using a connection cable (32) and a USB plug ( 33); Therefore, this type of charger (30) is still too large in overall size, and has a connecting cable (32}, which is not conducive to carry around, so it is still limited in use. Portable electronic products continue to improve, and the size of MP3 or PDA products has become thinner and lighter, and many use only a No. 3 / AA or No. 4 / AAA secondary battery, which is enough to supply the required power. Therefore, the charger used in such a secondary rechargeable battery seems to be developing in a direction of miniaturization and simplification. Moreover, when it is intended to be charged, the plug interface used must be the most easily available DC DC. The power supply is in order to meet the market demand, which is a problem to be solved by the present invention.
