The positions of the charging plug 402 are the same as those of the charging window 102 and the charging hole 302 respectively. Two electrode connection plates 403 are also fixedly connected to the circuit board 401. The electrode connection plates 403 are electrically connected to the battery pack electrodes 201. One of the electrode connection plates 403 is lapped with the inner wall of the metal housing 101, and this electrode connection plate 403 is electrically connected to the negative battery pack electrode 201;

[0046] The conductive cap mechanism 5 includes a sealing plate 501. On one side of the sealing plate 501, a battery positive electrode 502 is fixedly connected.

The connecting contact pin 503 penetrates through the end of the insulating sleeve 301 and is electrically connected to the charging plug 402, and the connecting contact pin 503 is connected to the positive electrode of the battery pack electrode 201.

[0047] Through the above technical solution, the metal housing 101 is provided to wrap the battery pack 2, and the insulating sleeve 301 is inserted at the end of the metal housing 101 to fix and isolate the circuit board 401. The charging plug 402 and the electrode connection plates 403 are installed on the circuit board 401. The circuit board 401 is electrically connected to the battery pack 2 through the electrode connection plates 403, and is connected to the mobile phone adapter through the charging plug 402, and is connected to the power supply through the mobile phone adapter to charge the battery pack 2, achieving the effect of improving the charging convenience of the battery;

[0048] A number of components are installed on the circuit board 401 to adjust the current and voltage. When charging, the voltage is adjusted to 1.5V and then the battery pack 2 is charged. The specific charging principle of the circuit board 401 is the same as that of the mobile phone lithium battery.

In the specific use process, it can be changed to a USB interface, a Lightning interface, a Micro-USB interface, etc., and is not limited to the interface shown in the attached drawings of this application;

[0050] The length and diameter of the entire battery are adapted as needed, generally being the diameter and length of No. 5 and No. 7 batteries.

[0051] Specifically, a support head 303 is fixedly connected to the end of the insulating sleeve 301, and the battery positive electrode 502 is sleeved on the support head 303;

[0052] A through hole 304 is opened at the end of the insulating sleeve 301. The through hole 304 is located on both sides of the support head 303, and the connecting contact pin 503 penetrates through the through hole 304 and extends into the interior of the insulating sleeve 301.

[0053] Through the above technical solution, a support head 303 is fixedly connected to the end of the insulating sleeve 301 to support the battery positive electrode 502, thereby preventing the protruding battery positive electrode 502 from deforming;

[0054] The purpose of providing a through hole 304 at the end of the insulating sleeve 301 is to enable the connection contact leg 503 to enter the inside of the insulating sleeve 301 to connect with the charging plug 402, and the through hole 304 can also limit the installation angle of the sealing disc 501.

[0055] Specifically, limiting sliding grooves 305 are symmetrically provided on the inner wall of the insulating sleeve 301, and the circuit board 401 is inserted into the limiting sliding grooves 305 for positioning;

[0056] One of the limiting sliding grooves 305 penetrates through the insulating sleeve 301 from the mouth of the insulating sleeve 301, and the penetrating limiting sliding groove 305 is penetrated by an electrode connection disc 403 that abuts against the inner wall of the metal housing 101.

[0057] Through the above technical solution, limiting sliding grooves 305 are provided on the inner wall of the insulating sleeve 301, so that the installation position and angle of the circuit board 401 can be limited by the limiting sliding grooves 305, ensuring that the mouth of the charging plug 402 is aligned with the charging window 102 and the charging hole 302;

[0058] After the circuit board 401 is installed, both sides are limited by the limiting sliding grooves 305 to prevent rotation, and the tail of the circuit board 401 is supported and limited by the battery pack 2, thereby preventing the circuit board 401 from sliding, thus achieving the complete positioning of the circuit board 401.

[0059] Specifically, the outer surface of the insulating sleeve 301 is in complete contact with the inner wall of the metal housing 101, and a boss is provided at the end of the insulating sleeve 301, and the diameter of the boss is greater than the inner diameter of the metal housing 101.

[0060] Through the above technical solution, the outer surface of the insulating sleeve 301 is in complete contact with the inner wall of the metal housing 101, which can improve the installation firmness of the insulating sleeve 301, and the boss provided at the end of the insulating sleeve 301 is used to prevent the insulating sleeve 301 from being completely inserted into the metal housing 101, thereby separating the sealing disc 501 from the metal housing 101 by the insulating sleeve 301 to prevent short circuit caused by contact between the metal housing 101 and the sealing disc 501.

[0061] Specifically, a through groove 404 is provided at the edge of the circuit board 401 below the electrode connection disc 403;

[0062] The middle of the electrode connection pad 403 is a concave arc surface, which extends between the through grooves 404. An elastic clip is arranged above the electrode connection pad 403, and the arc surface cooperates with the clip to contact and connect with the battery pack electrode 201.

[0063] Through the above technical solution, the through grooves 404 are opened at the edge of the circuit board 401, so that the middle part of the electrode connection pad 403 can be concave to form a groove, so as to increase the contact area between the electrode connection pad 403 and the battery pack electrode 201, convert the linear contact into surface contact, and the arranged clip is used to cooperate with the groove to further fix the battery pack electrode 201, so as to further improve the connection stability.

[0064] Specifically, the connection pins 503 include one long and one short. The long connection pin 503 is welded to the outer shell of the charging plug 402, and the short connection pin 503 is located at the bottom of the circuit board 401 and does not overlap with the circuit board 401.

[0065] Through the above technical solution, the connection pins 503 are set to be one long and one short, so that the long one can contact the charging plug 402 for electronic transmission, while the short connection pin 503 only cooperates with the through hole 304 to connect and limit the sealing disc 501, and can effectively avoid the short connection pin 503 from contacting the circuit board 401 and causing the circuit board 401 to short-circuit.

[0066] Specifically, a groove is provided at the opening of the metal shell 101, a pin 306 is provided at the edge of the insulating sleeve 301, the pin 306 is inserted into the groove, and the outer surface of the pin 306 is equal to the radian of the outer surface of the metal shell 101.

[0067] Through the above technical solution, a groove is provided at the mouth of the metal shell 101, and a pin 306 is provided at the edge of the insulating sleeve 301. The insulating sleeve 301 is installed at a unique angle by inserting the pin 306 into the groove. After assembly, the insulating sleeve 301 will not rotate due to being limited, resulting in an angle change of the charging plug 402 and making it inconvenient for the data cable to be inserted;

[0068] The shape of the arranged pin 306 is used to keep the connection between the metal shell 101 and the pin 306 as a complete cylinder.

[0069] Specifically, a test hole 307 is opened at the top of the insulating sleeve 301, and a battery cell test point 405 is arranged above the circuit board 401.

[0070] Through the above technical solution, the arranged test hole 307 is used to enable a tool to pass through the insulating sleeve 301 and contact the battery cell test point 405, so as to test the voltage of the battery cell on the circuit board 401.

[0071] During use, the battery pack 2 is wrapped by setting the metal housing 101, and the insulating sleeve 301 is inserted at the end of the metal housing 101 to fix and isolate the circuit board 401. The charging plug 402 and the electrode connection plate 403 are installed on the circuit board 401. The electrode connection plate 403 is electrically connected to the battery pack 2, and the charging plug 402 is connected to the mobile phone adapter, and the battery pack 2 is charged by connecting the mobile phone adapter to the power supply, achieving the effect of improving the convenience of battery charging;

[0072] By extending one of the electrode connection plates 403 to overlap with the inner wall of the metal housing 101, and at the same time extending one of the connection pins 503 to be electrically connected to the charging plug 402, when the battery pack 2 discharges, the electrode connection plate 403 makes the outer surface of the metal housing 101 become the negative electrode, and the battery positive electrode 502 is connected to the negative electrode of the battery pack 2 through the connection pin 503 to form a negative electrode, reducing the wiring inside the metal housing 101 and making the structure of the entire battery more compact.
