The second electrical connector 140 may be mounted to the second circuit board 120 and electrically connected to the second circuit board 120. The first electrical connector 130 is plugged with the second electrical connector 140, and when the first electrical connector 130 is plugged with the second electrical connector 140, the first electrical connector 130 is electrically connected with the second electrical connector 140. According to the embodiment of the application, the first electric connecting piece 130 is electrically connected with the second electric connecting piece 140 through the insertion connection of the first electric connecting piece 130 and the second electric connecting piece 140, so that the first circuit board 110 electrically connected with the first electric connecting piece 130 and the second circuit board 120 electrically connected with the second electric connecting piece 140 are electrically connected, the connection mode is simple and convenient, and the assembly efficiency of the circuit boards can be effectively improved. Meanwhile, the circuit board is electrically connected through the plugging of the electric connecting piece, compared with connection modes such as a flat cable and the like, on one hand, the operation such as welding wires can be avoided, the assembly is simpler and more convenient, and on the other hand, the problem that poor contact is easily caused by the fact that components in the charging box extrude the flat cable when the flat cable is connected can also be avoided.

The first electrical connector 130 and the second electrical connector 140 may have any structure, and only the first electrical connector 130 and the second electrical connector 140 can be plugged and connected electrically when plugged. Of course, to facilitate the fabrication of the first electrical connector 130 and the second electrical connector 140, the first electrical connector 130 may be one of a plug and a socket and the second electrical connector 140 may be the other of the plug and the socket. Specifically, when the first electrical connector 130 is a plug, the second electrical connector 140 may be a socket for use with the first electrical connector 130. When the first electrical connector 130 is a receptacle, the second electrical connector 140 may be a plug for use with the first electrical connector 130. The following description will be made in detail with reference to the first electrical connector 130 as a plug and the second electrical connector 140 as a socket for cooperating with the first electrical connector 130:

referring to fig. 6, the first electrical connector 130 may include a first mounting portion 131 and an electrical pin 132, the first mounting portion 131 is mounted on the first circuit board 110, the electrical pin 132 is mounted on a surface of the first mounting portion 131 away from the first circuit board 110, and the electrical pin 132 is electrically connected to the first circuit board 110 through the first mounting portion 131. The second electrical connector 140 includes a second mounting portion 141, the second mounting portion 141 is mounted on the second circuit board 120 and electrically connected to the second circuit board 120, a surface of the second mounting portion 141 facing away from the second circuit board 120 is provided with an electrical socket 1411 for cooperating with the electrical pin 132, the electrical pin 132 is plugged into the electrical socket 1411, and when the electrical pin 132 is plugged into the electrical socket 1411, the electrical pin 132 is electrically connected to the second mounting portion 141. In the above, by providing the first electrical connector 130 to include the first mounting portion 131 and the second electrical connector 140 to include the second mounting portion 141, the mounting between the first electrical connector 130 and the first circuit board 110 and between the second electrical connector 140 and the second circuit board 120 can be more stable. By arranging the electric pins 132 on the first mounting part 131 and arranging the electric pin slots 1411 matched with the electric pins 132 on the second mounting part 141, the electric pins 132 are plugged with the electric pin slots 1411, and the electric pins 132 are electrically connected with the second mounting part 141 when being plugged, so that the first electric connector 130 and the second electric connector 140 are simple in structure and convenient to process.

The first mounting portion 131 is mounted on the first circuit board 110 and electrically connected to the first circuit board 110 directly by solder. Of course, in order to reduce the amount of solder used, the first mounting portion 131 and the first circuit board 110 may be electrically connected by solder only at the electrical connection points, and then fixed by dispensing. Similarly, the second mounting portion 141 is mounted on the second circuit board 120 and electrically connected to the second circuit board 120 directly by soldering, or electrically connected to the electrical connection point only by soldering, and then fixed by dispensing.

In order to enhance the concealment of the electrical contacts of the first electrical connector 130 and the second electrical connector 140 and avoid the problem of electrical leakage, the first electrical connector 130 may have the same structure as the above structure and include a first mounting portion 131 and an electrical pin 132, referring to fig. 7, the second electrical connector 140 may include a third mounting portion 142, the third mounting portion 142 is mounted on the second circuit board 120, the third mounting portion 142 may be provided with a through hole 1421, the through hole 1421 penetrates through the third mounting portion 142 to connect to the surface of the second circuit board 120 and the surface of the third mounting portion 142 facing away from the second circuit board 120, the second electrical connector 140 may further include an electrical connector 143 matching the through hole 1421, and the electrical connector 143 is disposed in the through hole 1421 and electrically connected to the second circuit board 120. The surface of the electrical plug 143 facing away from the second circuit board 120 may be provided with an electrical socket 1431 for cooperating with the electrical plug 132, the electrical plug 132 being plugged into the electrical socket 1431, and the electrical plug 132 being electrically connected to the electrical socket 1431 when the electrical plug 132 is plugged into the electrical socket 1431. With the above arrangement, only the electrical plug 143 in the third mounting portion 142 is made of a conductive material and electrically connected to the second circuit board 120, and the electrical plug 143 is disposed in the through hole 1421 and is not exposed, so that the occurrence of a current leakage phenomenon can be reduced or even avoided. Meanwhile, the third mounting portion 142 is made of an insulating material, which can reduce the cost compared to a conductive material.

The third mounting portion 142 and the second circuit board 120 can be directly mounted by dispensing. The electrical connection of the electrical connector 143 to the second circuit board 120 may be made by soldering at the electrical contacts.

The first circuit board 110 and the second circuit board 120 may be any two circuit boards within the wireless headset charging box 100. For example, a circuit board capable of supplying power to the headset, a circuit board capable of being electrically connected to an external power source, a circuit board capable of being electrically connected to an indicator light, and the like may be included in the wireless headset charging box 100. In the embodiment of the present application, the first circuit board 110 may be a circuit board capable of supplying power to the headset, and the second circuit board 120 may be a circuit board capable of being electrically connected to an external power source, in this case, referring to fig. 4 and 5, the wireless headset charging box 100 may further include an energy storage unit 150 for supplying power to the headset and an electrical interface 160 for being electrically connected to the external power source. The energy storage unit 150 may be mounted on the first circuit board 110 and electrically connected to the first circuit board 110, and the electrical interface 160 may be mounted on the second circuit board 120 and electrically connected to the second circuit board 120.

The energy storage unit 150 may be any rechargeable battery that can be recycled. For example, the energy storage unit 150 may be a lithium ion battery, a lithium ion polymer battery, a nickel metal hydride battery, or the like. The mounting of the energy storage unit 150 on the first circuit board 110 may be arbitrary. Of course, in order to make the structure of the wireless headset charging box 100 small, the positional relationship between the energy storage unit 150 and the first circuit board 110 may satisfy: the energy storage unit 150 is parallel to the first circuit board 110. The energy storage unit 150 may be directly mounted on the first circuit board 110, and other components or supports may also be disposed between the energy storage unit 150 and the first circuit board 110, so that the energy storage unit 150 is mounted with the first circuit board 110 through the components or the supports. The implementation manner of electrically connecting the energy storage unit 150 with the first circuit board 110 may be arbitrary. For example, the energy storage unit 150 may be electrically connected to the first circuit board 110 in the following manner: the electrical contacts of the energy storage unit 150 are connected to the electrical contacts of the first circuit board 110 by wires.

The electrical interface 160 can be a Type-C socket, a Lightning socket, a USB2.0 socket, or a USB3.0 socket. The electrical interface 160 and the second circuit board 120 may be electrically connected in the following manner: the electrical contacts on the electrical interface 160 are directly connected to the electrical contacts on the second circuit board 120 by solder, or the electrical contacts on the electrical interface 160 are connected to the electrical contacts on the second circuit board 120 by wires.

Referring to fig. 1 and 9, the wireless headset charging box 100 may include a housing 170. The housing 170 may include a first case 171 and a second case 172. Wherein the first housing 171 defines a first receiving section a for placing the earphone. The first receiving section a may include a first sub-receiving section a1 for placing an ear grip of the headset and a second sub-receiving section a2 for placing an earpiece of the headset. The second housing 172 is located on a side of the first housing 171 facing away from the first receiving section a, and the second housing 172 is connected to the first housing 171 and jointly defines a second receiving section b, which includes a third sub-receiving section b1 corresponding to the first sub-receiving section a1 and a fourth sub-receiving section b2 corresponding to the second sub-receiving section a 2.

The correspondence of the third sub-containment interval b1 with the first sub-containment interval a1 and of the fourth sub-containment interval b2 with the second sub-containment interval a2 can be understood as: the direction in which the first sub-receiving section a1 points to the second sub-receiving section a2 is a second direction, the direction in which the third sub-receiving section b1 points to the fourth sub-receiving section b2 is a third direction, and the angle between the second direction and the third direction is 0 ° to 90 °. The first sub receiving area a1, the second sub receiving area a2, the third sub receiving area b1 and the fourth sub receiving area b2 are all three-dimensional areas, the second housing 172 has a carrying surface 1721 facing the first housing 171, specifically, the second direction may be a direction in which a centroid of a cross section of the first sub receiving area a1 in a direction parallel to the carrying surface 1721 points to a centroid of a cross section of the second sub receiving area a2 in a direction parallel to the carrying surface 1721, and the third direction may be a direction in which a centroid of a cross section of the third sub receiving area b1 in a direction parallel to the carrying surface 1721 points to a centroid of a cross section of the fourth sub receiving area b2 in a direction parallel to the carrying surface 1721.

The first circuit board 110 may be disposed in any one of the third sub-receiving section b1 and the fourth sub-receiving section b2, and the second circuit board 120 may be disposed in the other one of the third sub-receiving section b1 and the fourth sub-receiving section b2. Of course, since the ear stem is smaller in volume than the earpiece, the first sub-receiving section a1 for placing the ear stem may be smaller than the second sub-receiving section a2 for placing the earpiece, so that the third sub-receiving section b1 corresponding to the first sub-receiving section a1 may be larger than the fourth sub-receiving section b2 corresponding to the second sub-receiving section a 2. In this case, referring to fig. 4 and 9, the first circuit board 110 and the energy storage unit 150 may be selectively disposed in the third sub-receiving section b1 with a larger space, and the second circuit board 120 and the electrical interface 160 may be selectively disposed in the fourth sub-receiving section b2 with a smaller space. With the above arrangement, the energy storage unit 150 having a larger capacity can be placed in the third sub-accommodation section b1, and the power supply time of the energy storage unit 150 can be prolonged.

The arrangement orientation of the first circuit board 110 in the third sub-receiving section b1 may be arbitrary. In order to arrange the first circuit board 110 in the third sub-receiving space b1 neatly and smoothly, referring to fig. 4, the first circuit board 110 may be parallel to the carrying surface 1721. The parallelism of the first circuit board 110 and the carrying surface 1721 can be understood as follows: the surface of the first circuit board 110 facing the carrying surface 1721 and the surface of the first circuit board 110 facing away from the carrying surface 1721 are both parallel to the carrying surface 1721. Similarly, the arrangement orientation of the second circuit board 120 in the fourth sub-receiving section b2 may be arbitrary. In order to arrange the second circuit board 120 in the fourth sub-receiving space b2 neatly and smoothly, the second circuit board 120 may be parallel to the carrying surface 1721. The second circuit board 120 and the carrying surface 1721 are parallel to each other: the surface of the second circuit board 120 facing the carrying surface 1721 and the surface of the second circuit board 120 facing away from the carrying surface 1721 are both parallel to the carrying surface 1721.

The distance from the first circuit board 110 to the carrying surface 1721 may be equal to the distance from the second circuit board 120 to the carrying surface 1721, and at this time, the interval between the first circuit board 110 and the second circuit board 120 may be: the first circuit board 110 and the second circuit board 120 have a gap only in a direction parallel to the carrying surface 1721. When the first circuit board 110 and the second circuit board 120 have a gap in a direction parallel to the carrying surface 1721, the first electrical connector 130 and the second electrical connector 140 may be disposed at the gap between the first circuit board 110 and the second circuit board 120.

The distance from the first circuit board 110 to the carrying surface 1721 and the distance from the second circuit board 120 to the carrying surface 1721 may also be different, and at this time, the interval between the first circuit board 110 and the second circuit board 120 may be: the first circuit board 110 and the second circuit board 120 have a gap in a direction perpendicular to the carrying surface 1721. Specifically, the distance from the first circuit board 110 to the carrying surface 1721 may be smaller than the distance from the second circuit board 120 to the carrying surface 1721, in this case, the first electrical connector 130 may be mounted on the surface of the first circuit board 110 facing away from the carrying surface 1721, and the second electrical connector 140 may be mounted on the surface of the second circuit board 120 facing the carrying surface 1721. Certainly, in order to enable the third sub-receiving region b1 to accommodate the energy storage unit 150 with larger capacity, the distance from the first circuit board 110 to the carrying surface 1721 may be greater than the distance from the second circuit board 120 to the carrying surface 1721, at this time, the first electrical connector 130 may be mounted on the surface of the first circuit board 110 facing the carrying surface 1721, and the second electrical connector 140 may be mounted on the surface of the second circuit board 120 facing away from the carrying surface 1721.

When the distance from the first circuit board 110 to the carrying surface 1721 is different from the distance from the second circuit board 120 to the carrying surface 1721, in order to facilitate the electrical connection between the first electrical connector 130 on the first circuit board 110 and the second electrical connector 140 on the second circuit board 120, referring to fig. 4, the orthogonal projection of the first circuit board 110 on the carrying surface 1721 and the orthogonal projection of the second circuit board 120 on the carrying surface 1721 may have an overlapping region, if a portion of the first circuit board 110 corresponding to the overlapping region is defined as a first overlapping portion, and a portion of the second circuit board 120 corresponding to the overlapping region is defined as a second overlapping portion, the first electrical connector 130 may be mounted on the first overlapping portion, and the second electrical connector 140 may be mounted on the second overlapping portion.

When the first circuit board 110 and the earphone need to be electrically connected to achieve power supply, and the earphone needs to be placed in the first accommodating section a of the first housing 171 during charging, in order to facilitate the electrical connection between the first circuit board 110 and the earphone, referring to fig. 9, the first circuit board 110 should be located on a side of the third sub-accommodating section b1 close to the first housing 171, so that the distance from the first circuit board 110 to the carrying surface 1721 is generally greater than the distance from the second circuit board 120 to the carrying surface 1721.

To electrically connect the first circuit board 110 with the headset, the wireless headset charging box 100 may further include a third electrical connector, which may be mounted to the first circuit board 110 and electrically connected with the first circuit board 110. The third electrical connection can be a pogo pin probe. The electrical connection of the third electrical connector to the first circuit board 110 may be achieved by a wire connection. Referring to fig. 1, the first housing 171 may be provided with a second opening 1711 through which the first circuit board 110 may be electrically connected to the earphone, one end of a third electrical connector may be electrically connected to the first circuit board 110, and the other end of the third electrical connector may be disposed at the second opening 1711. Specifically, the second opening 1711 may be located at the first sub-receiving section a1 of the first case 171, so that the third electrical connector disposed at the second opening 1711 can be electrically connected with the electrical interface at the ear stem of the earphone. A bluetooth pairing interface 111 may also be provided on the first circuit board 110 to enable successful pairing of the headset with other devices.

The shape of the second circuit board 120 may be arbitrary. If the second circuit board 120 is divided according to the installation positions of the second electrical connector 140 and the electrical interface 160, referring to fig. 5, the second circuit board 120 may include a first portion 121, a second portion 122 and a third portion 123 arranged along the first direction N, wherein the second electrical connector 140 is installed on the first portion 121, the electrical interface 160 is installed on the third portion 123, the second portion 122 is connected to the first portion 121 and the third portion 123, and in order to reduce the weight of the wireless headset charging box 100, the width of the second portion 122 may be smaller than the width of the first portion 121 and the width of the third portion 123 along a direction parallel to the carrying surface 1721 and perpendicular to the first direction N.

In order to electrically connect the electrical interface 160 with an external power source, referring to fig. 1, 2 and 4, a first opening 173 for electrically connecting the electrical interface 160 with the external power source may be disposed on the housing 170, one end of the electrical interface 160 is electrically connected with the second circuit board 120, and the other end of the electrical interface 160 may be disposed at the first opening 173. Specifically, the first opening 173 may be provided on the first housing 171, may be provided on the second housing 172, or may be provided together with the first housing 171 and the second housing 172. Since the electrical interface 160 is disposed in the fourth sub-receiving space b2 corresponding to the handset, and the size of the handset is larger, the second sub-receiving space a2 for placing the handset extends to a larger extent towards the second housing 172, and therefore, for the convenience of disposing the electrical interface 160, the first opening 173 is preferably disposed on the second housing 172.

In order to mount the first circuit board 110, the second circuit board 120, and the like stably in the second receiving space b, referring to fig. 4 and 10, the wireless headset charging box 100 may further include a support member 180. The supporting member 180 may be disposed on the supporting surface 1721, and both the first circuit board 110 and the second circuit board 120 may be disposed on the supporting member 180.
