Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 to 8, the present embodiment provides a power connector, which includes a main body 1, including a base 11 and a contact member 12, where the contact member 12 is elastically and telescopically assembled on the base 11; the power connector also comprises a sliding sleeve 2, and the main body 1 is axially and slidably assembled in a tube cavity of the sliding sleeve 2 and is consistent with the elastic expansion and contraction direction of the contact piece 12. In the structure of the power connector, two bodies 1 and a sliding sleeve 2 which can slide relatively are actually included, and it can be understood that another power connector is formed by additionally providing the sliding sleeve 2 on the original body 1. After the contact piece 12 is assembled in the lumen of the sliding sleeve 2, the contact piece can be fixed by riveting, sealing and further elastically stretched in the lumen of the sliding sleeve 2 without falling out.

Based on the relative sliding assembly structure of the main body 1 and the sliding sleeve 2, when the earphone is installed in the charging box, although the charging end 61 of the earphone will be in contact with the contact piece 12 of the main body 1, elastic abutment is formed by the elastic expansion effect between the contact piece 12 and the base 11, and in turn, abutment force is formed on the charging end 61 of the earphone. However, since the main body 1 and the sliding sleeve 2 are assembled in a relative sliding manner, when the earphone is taken out from the charging box, the corresponding structure on the earphone can form an abutting force on the whole body of the main body 1, the abutting force can push the main body 1, so that the main body 1 can slide relative to the sliding sleeve 2 and further retract into the sliding sleeve 2, and thus the main body 1 can prevent the earphone from being taken out to form a barrier, and the earphone can be taken out conveniently.

Further, the elastic telescopic connection of the contact piece 12 may be a direct connection manner or an indirect connection manner, for example, the elastic piece 13 is further included, and the contact piece 12 is elastically and telescopically assembled on the base 11 through the elastic piece 13. At this time, the elastic member 13 may provide an elastic force to enable the contact member 12 to be telescopically fitted on the base 11.

Furthermore, in order to facilitate the installation of the contact piece 12, the end face of the head of the base 11 is provided with a connecting seat 14, one end of the elastic piece 13 is connected with the connecting seat 14, and the other end of the elastic piece is connected with the contact piece 12, so that a connectable part can be provided for the contact piece 12, and the installation of the contact piece 12 is facilitated. Furthermore, a connecting groove 15 is formed in the connecting seat 14, and the end of the elastic element 13 is inserted and fixed in the connecting groove 15, so as to form a connection with the connecting seat 14. At this time, as long as the end of the elastic element 13 is inserted into the connecting groove 15, the elastic element 13 and the connecting seat 14 can be conveniently and fixedly connected, and when the two are required to be relatively disassembled, the elastic element 13 can be directly pulled out relative to the connecting groove 15.

Further, for the case that the sliding sleeve 2 is installed in the charging box, the sliding sleeve 2 may be directly connected to a corresponding position of the charging box, or may be indirectly connected to a corresponding position of the charging box, for example, an annular extension plate 21 is provided on a rear end surface of the sliding sleeve 2 for providing an adhesive layer. At this time, since the extension plate 21 of the slide bushing 2 has an adhesive layer, the adhesive layer may be connected to a corresponding position of the charging box. And the bonding layer can adopt a strong double-sided adhesive tape to bond the charging box and the sliding sleeve 2 together, and also can have a corresponding waterproof function.

Furthermore, in order to make the power connector have a waterproof function, when the main body 1 slides relative to the sliding sleeve 2, water leakage between the main body 1 and the sliding sleeve 2 can not happen, and therefore a waterproof piece 3 is further arranged and is arranged between the main body 1 and the sliding sleeve 2 in a sealing mode to play a waterproof role between the main body 1 and the sliding sleeve 2, and waterproof in the telescopic process is achieved. In one embodiment, the circumferential outer wall of the base 11 is provided with an annular groove 16, and the waterproof member 3 is a waterproof ring which is sleeved in the annular groove 16 and is in sealing contact with the inner wall of the lumen of the sliding sleeve 2. Therefore, the waterproof ring can form a waterproof effect on the circumference of the base 11, and no water leakage or electric leakage between the main body 1 and the sliding sleeve 2 is ensured no matter how the main body slides relative to the sliding sleeve. In one embodiment, the sliding sleeve 2 is a metal sleeve, the metal sliding sleeve 2 has better strength than other materials such as plastic, and the wall thickness can be thinner, so as to achieve the effect of saving space. Contact 12 is the needle, waterproof circle is the waterproof silica gel circle that liquid silica gel was moulded plastics and is formed, and waterproof silica gel circle is owing to adopt the liquid silica gel mode of moulding plastics, and what can do is littleer and promotes production efficiency.

The application also provides an earphone charging box, which comprises a box body 4, wherein an earphone accommodating groove 41 is formed in the box body; the box body 4 is provided with a cover body 5; the earphone also comprises the power connector, and a sliding sleeve 2 of the power connector is fixed in the earphone accommodating groove 41. Since the detailed structure, functional principle and technical effect of the power connector are described in detail in the foregoing, detailed description is omitted here. For any technical content related to the power connector, reference may be made to the above description.

The application also provides a wireless earphone, which comprises at least one earphone body 6, wherein a charging end 61 is arranged in the earplug of the earphone body 6; also included is the earphone charging box, the power connector being opposite the charging end 61. At this time, the earplug position of the earphone body 6 can be provided with a corresponding flange 62, and the flange 62 can form an abutting force on the whole of the main body 1 when the earphone body 6 is taken out, and the abutting force can push the main body 1 to enable the main body 1 to slide relative to the sliding sleeve 2 and further retract into the sliding sleeve 2, so that the main body 1 can prevent the earphone from being taken out to form a barrier, and the earphone is convenient to take out. The arrow "a" in the drawing indicates the direction in which the earphone body 6 is taken out. Moreover, the earphone body 6 may be a single body or a pair, even if it is a wireless earphone for multiple persons, it may also be provided with multiple earphone bodies 6 at the same time, which may be set according to the needs of those skilled in the art, and is not limited herein.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
