specific Embodiment approach 1

[0019] Such as Figure 1-3 As shown, the Bluetooth earphone battery includes a PCB board 1, a battery cell 2 and a protective layer 3, and the battery cell 2 is provided with a positive pole tab 21 and a negative pole tab 22, and a positive pole tab 21 and a negative pole tab 22 are provided on the PCB board 1. The positive electrode lead 11 and the negative electrode lead 12 that are matched with the negative electrode lug 22, the PCB board 1 and the battery cell 2 are superimposed on each other, the protective layer 3 wraps the PCB board 1 and the end of the connection between the PCB board 1 and the battery cell 2, the protective layer 3, the PCB board 1 and the end where the PCB board 1 and the battery cell 2 are connected form a relatively sealed space, the protective layer 3 is integrally formed, and the positive electrode lead 11 and the negative electrode lead 12 pass through the protective layer 3 and are relatively exposed on the outside.

Abstract

According to the Bluetooth earphone battery disclosed by the invention, a PCB is wrapped on a battery cell by a protective layer of the Bluetooth earphone battery, i.e., the PCB is sealed between theprotective layer of the Bluetooth earphone battery and the battery cell, so that on one hand, the PCB can be protected from being damaged, and on the other hand, water can be prevented from entering in a relatively sealed space, and accordingly, the Bluetooth earphone battery cannot be damaged when falling into water or being affected with damp. Meanwhile, the protective layer is used for replacing the traditional upper and lower cover packaging, the manufacturing process is simplified, direct integrated packaging is achieved through the protective layer, the process is simple, and the cost islow.

Description

technical field [0001] The invention relates to the field of bluetooth earphone batteries, in particular to a bluetooth earphone battery. Background technique [0002] In the manufacturing process of the Bluetooth headset battery, in order to reduce the size of the battery and waterproof, it is necessary to package the battery cell and the PCB board together. One of the existing technologies is to package the two through a shell with an upper and a lower cover. However, this solution has cumbersome processes, cumbersome procedures and high cost. The other is to glue the battery cell and the PCB board together with glue, and then package it. This process is relatively simple and the cost is low. However, the glue used for bonding often appears in the process of bonding the two. Damage to the PCB board or battery, or viscosity, often easy to crack and not sealed. Contents of the invention [0003] The invention provides a Bluetooth earphone battery, which solves the tradit...
