Description

technical field [0001] The invention belongs to the technical field of bluetooth earphones, in particular to a charging pin for bluetooth earphones. Background technique [0002] The Bluetooth headset needs to be charged after using it for a period of time. The Bluetooth headset charging box is a portable mobile power supply, which is very convenient to use. When charging, just put the Bluetooth headset into the corresponding headset slot. Good storage of Bluetooth headsets to avoid loss of Bluetooth headsets. However, when carrying the charging box out, the Bluetooth earphones placed in it tend to shift under frequent vibrations, resulting in incomplete contact of the charging contacts or poor contact affecting the charging effect. [0003] There are also some technical solutions in the prior art. For example, the Chinese patent with application number CN201621481659.4 includes a needle tube and a needle shaft. A spring is installed in the needle tube. A polygonal contact...

However, when carrying the charging box out, the Bluetooth earphones placed in it tend to shift under frequent vibrations, resulting in incomplete contact of the charging contacts or poor contact affecting the charging effect

[0003] There are also some technical solutions in the prior art. For example, the Chinese patent with application number CN201621481659.4 includes a needle tube and a needle shaft. A spring is installed in the needle tube. A polygonal contact surface is provided on the contact end of the spring, and several chamfered connection surfaces are provided between the contact surface and the needle shaft. However, in actual use, although the polygonal contact surface increases the stability of the connector contact , but there is still the problem that the processing accuracy is difficult to guarantee. In fact, some contact surfaces cannot be energized due to the gap during installation.
