Description

A clamping mobile phone battery multi-channel charger

technical field

The utility model relates to the technical field of mobile terminal lithium battery charging applications, in particular to a clip-type mobile phone battery multi-channel charger. the

Background technique

When mobile phone suppliers sell mobile phones to customers, they often need to pre-charge the battery in the mobile phone. If you open the charger in the mobile phone package to charge, it is not only troublesome but also not conducive to the integrity and aesthetics of the factory package that comes with it. Therefore, mobile phone sales At present, merchants generally use the method of clamping the mobile phone battery to the common mobile phone universal charger on the market for charging, but each universal charger can only charge one battery at a time in design, and because of the volume, The universal charger should occupy the position of 2-4 sockets on the power socket, so when it is necessary to charge multiple mobile phone batteries, it will occupy multiple power sockets, which is not only wasteful, but also takes up the space on the desktop, so that the operator is charging multiple batteries. It is very inconvenient when the mobile phone battery is charging. the

Contents of the invention

The utility model provides a multi-channel battery charger for a clamping mobile phone. The charger is made into a rectangular box structure, and 4-N USB international general power sockets are arranged around the box body, and each socket can be connected through a belt. The power line of the USB plug leads to a 4.2V low-voltage charging power supply, and the charging clip connected to it holds the battery of the mobile phone for charging. It takes up less space on the desktop and is easy to use. It can quickly charge 4-N mobile phone batteries at a time, and automatically. Identify the characteristics of reversing the battery polarity for charging. the

The present invention achieves the above object through the following technical solutions: a multi-channel battery charger for a clip-on mobile phone, including: a charger housing, an AD power converter, a charging polarity intelligent identification conversion chip, a USB electrical socket, and a plug connection , a charging clip and a mains plug line, characterized in that: the charger uses a charging polarity intelligent identification conversion chip, and is connected with the battery charging using a charging clip. the

The charging polarity intelligent recognition conversion chip can use a model of SDC3733 or a series of lithium battery charging intelligent management chips with an output voltage of 4.2V and an output current of 200-500mA. When the charger accidentally connects the battery polarity of the mobile phone, The chip circuit can automatically identify and adjust the polarity to ensure the normal charging of the battery. the

The charging clip refers to a special mobile phone battery charging clip with two retractable charging electric needles a, a charging indicator light tube b and a V85P model international universal power socket c installed in the middle of the plastic clip. It is to clamp the battery of the mobile phone and charge the charging power through the charging needle a to contact the battery electrode to charge the mobile phone battery by transmitting power. the

Beneficial effects of the utility model: the utility model provides centralized power supply through the charger, multi-channel output, and uses the electric needle contact charging clip to charge the battery of the mobile phone. It has the advantages of flexible and convenient charging, many rechargeable batteries, and automatic adjustment and conversion of charging polarity. Occupying less desktop space, it is suitable for consumers who need to charge multiple mobile phone batteries at the same time. Embodiments of the utility model can be described in detail in conjunction with the accompanying drawings. the

Figure 2 is a schematic structural diagram of the contact charging clip of the present invention. the

3 among the figure is the block diagram of working principle of the utility model. the

In the figure 1 charger shell, 2AD power converter, 3 charging clip, 4 charging polarity intelligent recognition conversion chip, 5USB charging socket, 6 charging plug connection, 7 power switch, 8 mains power indicator light, 9 low-voltage power supply Indicator lights, 10 mains plug wires, 11 lithium batteries.

Detailed ways

Referring to Fig. 1 and Fig. 2, the utility model is a multi-channel charger for clamping mobile phone batteries, including a charger housing 1, an AD power converter 2, a charging clip 3, a charging polarity intelligent recognition conversion chip 4, and a USB charging socket 5. The charging plug connection 6, the power switch 7, the mains power indicator 8, the low-voltage power supply indicator 9, and the mains plug line 10 are composed. The production and installation process of the utility model product is as follows: the AD power converter 2 Charging polarity intelligent recognition conversion chip 4USB charging socket 5 mains power indicator light 8 low-voltage power supply indicator light 9 and mains plug line 10 joints are integrally installed and welded on a circuit board, and then fixed in the charger housing 1 with screws On the base, install the power switch 7 on the top cover of the charger housing 1, insert the mains plug line 10 plug into the 220V mains socket, check and adjust the output of the circuit to buckle the top cover of the charger housing 1 after checking that the output is normal, and complete the utility model product manufacturing process. (The utility model patent application has been submitted separately for the charging clip 3, and the installation and production process will not be repeated here). the

Referring to Fig. 1, Fig. 2 and Fig. 3, the use and working principle process of the utility model is described as follows: insert the charger power cord into the mains socket, turn on the power switch 7, the mains power indicator light 8 is on, and the charger gets the mains. When the low-voltage power supply indicator light 9 is always on, the AD power converter 2 starts to work, insert the USB plug of the charging plug connection 6 into the charging socket 5, and insert the connector plug at the other end into the input socket c of the charging clip 3, and charge on the charging clip 3 The status indicator light b emits yellow light, indicating that it is waiting for charging. Pinch open the charging clip 3, and clip the lithium battery 14 electrodes to be charged forward into the charging clip. The charging needle a is closely connected, and the charging status indicator b flashes at this time, indicating that the charging is normal. After the lithium battery 11 is fully charged, the charging status indicator b turns green and is always on, indicating that the charging is complete. the

When the +- polarity of the battery clamped by the user is reversed and the +- polarity of the charging pin output is opposite, the charging polarity intelligent recognition conversion chip installed in the charger corresponding to the output of this channel will automatically make a judgment and switch Charging output voltage polarity, so that the battery can be charged normally. the
