TWS earphone

Abstract

The invention discloses a TWS earphone, which comprises a circuit board and a power line used for being electrically connected with the circuit board. The power line comprises a conductive wire made of a metal material and an insulating layer coating the conductive wire, and a conduction connecting frame capable of elastic deformation is pasted on the circuit board; a connecting groove with an outward opening is formed in the conduction connecting frame, and a gap with the width smaller than the diameter of the conductive wire is formed between the groove walls of the two opposite sides of theconnecting groove; cutter assemblies are arranged on the groove walls of the two opposite sides of the connecting groove or the groove edges of the two opposite sides of a groove opening of the connecting groove. A cutting gap is formed in the cutter assembly, when the power line is extruded to enter the gap along the cutting gap, the cutter cuts the insulating layer open, the conductive wire passes through the cutting gap, and the two opposite sides of the conductive wire abut against the groove walls of the two opposite sides of the connecting groove respectively. According to the TWS earphone provided by the invention, the conduction connection with the power line is realized through the conduction connecting frame capable of elastic deformation, so that the welding and fixing operation is omitted, and the effects of electric conduction and fixing are also achieved.

Description

technical field [0001] The invention relates to the technical field of bluetooth earphones, in particular to a TWS earphone. Background technique [0002] TWS (True Wireless Stereo) earphones, that is, true wireless stereo earphones, use Bluetooth connections instead of physical wires, which are more convenient to use and are favored by consumers. [0003] In the prior art, the battery in the TWS earphone is connected to the circuit board in the TWS earphone through two power lines, and the power line is soldered to the circuit board by an electric soldering iron. However, due to the small size of the TWS earphones, and the position accuracy of the solder connection is generally below 0.1mm, the solder connection method is likely to generate high-temperature radiation and damage the electronic components around the solder point, and the solder connection method is likely to cause product yield. The result of the decline is not conducive to improving the reliability of TWS e...
