Charging device and headphone components

Abstract

This novel embodiment provides a charging device and an earphone assembly. The charging device includes a carrier portion and a conductive spring. The carrier portion has a receiving groove and a limiting groove communicating with the receiving groove. The conductive spring includes a feed plate, with a portion of the conductive spring confined within the limiting groove. The feed plate extends from the limiting groove and bends to fit against the outer surface of the carrier portion. By setting the feed end of the conductive spring as a feed plate and directly exposing it to the outside of the carrier portion, this charging device allows the conductive spring to directly connect to the internal circuit board for electrical connection, eliminating the need for an intermediate bridge structure. This significantly simplifies the assembly process, reduces costs, and improves product yield.

Claims

1. A charging device comprising: A support portion having a receiving groove and a limiting groove communicating with the receiving groove; and a conductive spring including a power supply plate, the conductive spring being partially confined within the limiting groove, the power supply plate extending from the limiting groove and bending to fit against the outer side of the support portion.

2. The charging device as claimed in claim 1, wherein, The limiting groove has a port, and the power supply plate includes a first curved section, a connecting plate, a second curved section and a power supply contact plate connected in sequence. The first curved section extends from the port, and the power supply contact plate is connected to the connecting plate through the second curved section and fits against the outer side of the support portion.

3. The charging device as claimed in claim 2, wherein, The conductive spring also includes a fixing part, a connecting part, a contact part and an abutting part, all of which are confined within the limiting groove and connected in sequence. The fixing part is connected to the first curved section. The contact part has an electrical contact surface near the abutting part. The electrical contact surface is located within the receiving groove. The abutting part abuts against the inner wall of the limiting groove.

4. The charging device as claimed in claim 3, wherein, The charging device also includes a positioning part disposed in the limiting groove, a fixing part disposed in the positioning part, and a power supply plate extending out from the positioning part.

5. The charging device as claimed in claim 4, wherein, The fixing part includes a third curved section, a fourth curved section, and a first connecting section connecting the third curved section and the fourth curved section. The third curved section is connected to the end of the connecting part away from the abutting part, and the fourth curved section is connected to the first curved section.

6. The charging device as claimed in claim 5, wherein, The connecting portion includes a fifth curved section, a second connecting section, a sixth curved section and a third connecting section connected in sequence. The contact portion is connected to the end of the fifth curved section, and the third connecting section extends from the sixth curved section to the positioning portion and connects with the fixing portion.

7. The charging device as claimed in claim 4, wherein, The bearing part has a positioning recess on the side near the port that communicates with the limiting groove, and the positioning part is disposed in the positioning recess; the side of the positioning part near the port and the positioning recess form a groove structure, and an adhesive structure is cured in the groove structure.

8. The charging device as claimed in claim 1, wherein, The support unit includes: a first housing including a receiving groove with two windows; two second housings disposed opposite to and spaced apart from the outer side of the first housing, the limiting grooves being disposed in the second housings, and the two limiting grooves communicating with the receiving grooves through the two windows respectively; each limiting groove is configured to install a conductive spring, and two power supply plates extend from the two limiting grooves and bend and extend to be attached to the outer side of the two second housings respectively.

9. The charging device as claimed in claim 8, wherein, The charging device also includes a power supply section, which includes a circuit board and two power supply contacts. The two power supply contacts are disposed on the circuit board and are electrically connected to the two power supply boards respectively.

10. An earphone assembly comprising: A charging device as described in any one of claims 1 to 9; And an earphone, the charging device being configured to charge the earphone.
