Charging elastic pin for Bluetooth earphone

Abstract

The invention belongs to the technical field of Bluetooth earphones, and particularly relates to a charging elastic pin for a Bluetooth earphone. The charging elastic pin comprises a shell and a pinshaft. A mounting hole is formed in the shell. The pin shaft is mounted in a mounting hole in the shell. A contact ring is arranged at the lower end of the pin shaft. The contact ring is in contact with the inner wall of the mounting hole. A guide groove is formed in the side wall of the mounting hole. The number of the guide grooves is two. The guide grooves are symmetrically distributed in the inner wall of the mounting hole. A guide rod is mounted on the contact ring. The guide rod is perpendicular to the center line of the pin shaft. The number of the guide rods is two, and the two guide rods are symmetrically distributed on the contact ring. The guide rod can be inserted into the guide groove and can freely move in the guide groove. Springs are mounted in the mounting holes. The charging elastic pin is simple in structure, high in reliability and good in connection stability, and the outage risk in the connection process is avoided.

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.
