Technical Field

[0001] The present invention relates to the technical field of batteries, and in particular to a handheld terminal. Background Art

[0002] With the development of technology, handheld terminals include dry batteries / lithium batteries that need to be replaced and battery assemblies that can be charged and discharged and are integrated with the terminal body. The latter have a longer service life, are simpler to use, and are cleaner during use. They have gradually replaced the dry batteries / lithium batteries that need to be replaced. In the prior art, the battery assembly that can be charged and discharged and is integrated with the terminal body can power the electrical components of the terminal body through the set battery cells and battery protection boards, but there is still room for improvement.

[0003] In the prior art, the electrical connector of the battery protection board of the handheld terminal needs to pass through the bottom wall of the shell to be electrically connected to the battery connector, and the battery connector adapted thereto needs to be installed in the terminal body relative to the bottom of the shell, which increases the thickness of the terminal body and the battery as a whole, resulting in a thicker and heavier device as a whole. To solve this problem, the overall thickness of the terminal body is made smaller. In addition, the battery waterproof performance of the existing handheld terminal is poor, liquid can easily enter the battery, and its internal components can easily be damaged by water immersion. A handheld terminal is proposed. Summary of the invention

[0020] It can be seen from the above technical solution that the buckle and the hook can make the shell and the terminal body detachably connected.

[0021] Furthermore, a glue injection hole is provided on the shell, and glue is injected into the interior of the shell through the glue injection hole. After the glue solidifies, the shell, the battery cell and the battery protection plate are fixed together by the glue to form the battery.

[0022] It can be seen from the above technical solution that the glue can fix the battery cell and the battery protection board on the one hand, and prevent liquid from entering the interior of the shell on the other hand.

[0023] Furthermore, the battery cell and the battery protection board are placed side by side inside the shell, and the battery cell and the battery protection board are electrically connected.

[0024] It can be seen from the above technical solution that placing the battery cells and the battery protection board inside the shell can make more reasonable use of the internal space of the shell.

[0025] (III) Beneficial effects

[0026] The handheld terminal of the present invention has the following beneficial effects: the electrical connector of the battery protection board passes through the side wall of the shell, and the battery connector is arranged relative to the side wall of the shell. Compared with the prior art in which the electrical connector passes through the bottom of the shell and the battery connector is arranged relative to the bottom of the shell, this design can reduce the overall thickness of the terminal body and the battery after they are combined, thereby reducing the thickness of the entire machine. In addition, after the battery is assembled, the close contact between the battery and the waterproof component makes it extremely difficult for liquid to enter the battery, which can improve the waterproof performance of the battery of the handheld terminal.
