Abstract

The invention discloses a Bluetooth headset battery, wherein a PCB is wrapped on a battery core by a protective layer of the Bluetooth headset battery, namely the PCB is sealed between the protective layer of the Bluetooth headset battery and the battery core, so that on one hand, the PCB can be protected from being damaged, and on the other hand, water can be prevented from entering a relatively sealed space, so that the Bluetooth headset battery cannot be damaged when falling into water or being affected with damp. Meanwhile, the protective layer replaces the traditional upper cover and lower cover packaging, the manufacturing process is simplified, the protective layer is directly packaged integrally, the process is simple, and the cost is low.

Description

Bluetooth headset battery

Technical Field

The invention relates to the field of Bluetooth headset batteries, in particular to a Bluetooth headset battery.

Background

In bluetooth headset battery manufacturing process, in order to reduce the volume and waterproof of battery, need encapsulate electric core and PCB board together, and the one kind of prior art is with both through the shell encapsulation that possesses upper and lower cover together, but, this scheme exists that technology is loaded down with trivial details, and the process is troublesome, and the cost is higher. The other method is to bond the cell and the PCB together by glue and then encapsulate the cell and the PCB, which is relatively simple and low in cost, but the glue used for bonding often damages the PCB or the cell or has viscosity and often cracks or is not sealed during the bonding process.

Disclosure of Invention

The invention provides a Bluetooth headset battery, which solves the problems that in the traditional method, a battery core and a PCB are packaged together through a shell of an upper cover and a shell of a lower cover or are packaged after being pasted together through glue, the process is complicated, the cost is high, cracking occurs, the sealing is not performed, and the like.

In order to solve the technical problems, the technical scheme of the invention is as follows: the utility model provides a bluetooth headset battery, includes PCB board, electric core and protective layer be equipped with anodal utmost point ear and negative pole utmost point ear on the electric core be equipped with on the PCB board with anodal utmost point ear with the anodal lead wire and the negative pole lead wire that negative pole utmost point ear matches to be connected, the PCB board with the electric core is relative superposes, the protective layer parcel the PCB board with the one end that the electric core is connected, the protective layer the PCB board with the one end that the electric core is connected forms relative sealed space, the protective layer is the integrated into one piece structure, anodal lead wire with the negative pole lead wire passes the protective layer exposes in the outside relatively.

Preferably, a film pasting layer is arranged at the bottom of the other end of the battery cell, which is connected with the PCB board and the battery cell.

Preferably, the protective layer surrounds the whole body of the battery cell, the bottom edge of the protective layer is flush with the bottom edge of the battery cell, and the adhesive film layer and the protective layer form a relatively sealed space.

Preferably, an insulating protective sheet for preventing short circuit is provided on each of the ends of the positive electrode lead and the negative electrode lead.

Preferably, the insulating protective sheet is a paper sheet.

Preferably, the protective layer is integrally formed by injection molding.

Preferably, the protective layer is made of plastic.

The invention has the following beneficial effects: (1) according to the Bluetooth headset battery, the PCB is wrapped on the battery core through the protective layer, namely the PCB is sealed between the Bluetooth headset battery protective layer and the battery core, so that on one hand, the PCB can be protected from being damaged, and on the other hand, water can be prevented from entering a relatively sealed space, so that the Bluetooth headset battery cannot be damaged when falling into water or being affected with damp. (2) Meanwhile, the protective layer replaces the traditional upper cover and lower cover packaging, the manufacturing process is simplified, the protective layer is directly packaged integrally, the process is simple, and the cost is low.
