Abstract

The utility model relates to a charger inside a mobile phone. When charged, the mobile phone is placed on a charger base. The surface of the charger base is provided with a positive electrode and negative electrode, which are post-shaped and are unequal in length. The charger comprises a positive terminal, a negative terminal, a first spring piece and a second spring piece, wherein, during charging, pushed by the positive electrode of the base, the first spring piece moves upwards to be electrically contacted with the positive terminal, and pushed by the negative electrode of the base, the second spring piece moves upwards to be electrically contacted with the negative terminal.

Description

Charging device in the mobile phone

The utility model relates to the charging device in a kind of mobile phone.

Its both positive and negative polarity of prior mobile phone charger has directivity, if the poor direction that battery is put when charging is true, has the phenomenon of error-polarity connection, and damages or danger, causes battery to be damaged at last.

The purpose of this utility model is to propose the interior charging device of a kind of improved mobile phone.

For this reason, the utility model provides the charging device in the mobile phone, when to this mobile phone charging, mobile phone is placed on the charger pedestal, this charger base-plates surface has an anodal and negative pole, and both become column and are uneven in length, and charging device comprises: a positive terminal; One negative pole end; One first shell fragment can be subjected to the ejection of pedestal positive pole during charging and move upward to become electric contact state with positive terminal.One second shell fragment, it is subjected to the pushing tow of pedestal negative pole and moves upward to become electric contact state with negative pole during charging.

The utility model has the advantages that regardless of the telephone set battery and put direction, do not have polarity and connect anti-phenomenon.

Below, embodiment of the present utility model is described in conjunction with the accompanying drawings, among the figure:

Figure 1 shows that the state when the interior charging device of mobile phone does not contact with pedestal as yet;

Figure 2 shows that the state when the interior charging device of mobile phone contacts with pedestal.

Charging device 11 in the mobile phone of the present utility model as shown in Figure 1 is used a charger pedestal 12, and charger pedestal 12 surfaces have a positive pole 13, a negative pole 14; Both are column and are uneven in length.

Charging device 11 comprises a positive terminal 15, a negative pole end 16, one first shell fragment 17, one second shell fragment 18.

Shell fragment

17,18 was not stretched condition when charging device 11 placed on the pedestal 12 as yet, as shown in Figure 1.

First shell fragment 17 is subjected to the ejection of pedestal positive pole 13 to shrink and move upward and 15 one-tenth electric contact states of positive terminal during charging; And second shell fragment 18 is subjected to the ejection contraction of pedestal negative pole 14 and moves upward and 16 one-tenth electric contact states of negative pole end, as shown in Figure 2.

When the length of negative pole 14 than anodal 13 in short-term, negative pole end 16 just must be arranged at the below of positive terminal 15.In like manner, when the length of negative pole 14 compared positive pole 13 length, negative pole end 16 just must be arranged at the top of positive terminal 15.

By structure of the present utility model as can be known, regardless of the phone placement direction, anodal 13 perseverances and 15 one-tenth electric contact states of positive terminal of pedestal, pedestal negative pole 14 permanent and 16 one-tenth electric contact states of negative pole end, polarity cooperates inevitable correct, does not have the situation generation that any battery is damaged.

Claims

1, the charging device in a kind of mobile phone, when to this mobile phone charging, mobile phone is placed on the charger pedestal, and this charger base-plates surface has an anodal and negative pole, both are column and are uneven in length, and it is characterized in that this charging device comprises:

One positive terminal;

One negative pole end;

One first shell fragment can be subjected to the ejection of pedestal positive pole during charging and move upward to become electric contact state with positive terminal;

One second shell fragment can be subjected to the ejection of pedestal negative pole during charging and move upward to become electric contact state with negative pole end.
