Technical Field

[0001] The utility model relates to the technical field of shrapnel, in particular to a shrapnel connector applicable to a headphone box. Background Art

[0002] With the continuous progress of the economy, the scientific and technological level is also constantly innovating and developing. Electronic products such as mobile phones, headphones, and tablets have become essential necessities in people's lives, providing a lot of help for life, making life more convenient, and enriching people's spiritual world, enabling people to understand different worlds and listen to different music without leaving home, greatly increasing people's spiritual wealth.

[0003] Among them, during the use of Bluetooth headphones, there is no need to worry about the winding situation of traditional wired headphones, making it more convenient. However, the Bluetooth headphone box paired with it is used to charge the Bluetooth headphones at any time, so that the Bluetooth headphones can be charged at any time to avoid the situation of power shortage during the next use.

[0004] In the current shrapnel connector in the Bluetooth headphone box, during long-term use, the end cover at its upper end is prone to displacement and misalignment, making the shrapnel connector prone to poor contact and unable to be fixed. And in the shrapnel connector, the elastic connecting piece inside it is prone to slipping out of the accommodating chamber, resulting in the contact end on the elastic connecting piece being unable to correctly form an electrical connection with the Bluetooth headphones, making the Bluetooth headphones unable to be charged and used normally, affecting the user experience.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Content of the Utility Model
