[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0024] The existing Type-c interface usually adopts a 16-pin structure, 16 pins are symmetrically arranged on two surfaces of a tongue plate, the 16 pins include positive terminals for charging, ground terminals and terminals for transmitting data, and the positive terminals and the ground terminals are arranged on each surface. Since there are many pins, two planes of 8 pins are respectively injection molded and then assembled together, and then a one-time injection molding is performed to form a shape, so the process is relatively complex and the cost is relatively high.

[0025] Meanwhile, when the Type-c interface is applied to electronic devices such as earphones, since the jack connected with the female seat interface is open, liquid ingress is prone to occur, and since the number of pins is large, the positive terminals and the ground terminals are close to each other, under the influence of liquid drops, short circuit and burnout risk may be caused. And for electronic devices such as earphones, the existing Type-c interface is usually only used for charging operation, so part of the 16 pins of the existing Type-c interface is redundant, which increases the manufacturing cost.

[0026] Based on this, the inventors of the present application have long-term research and propose a charging female seat interface, a charging male seat, an earphone box and an earphone assembly to reduce the short circuit risk of the charging female seat interface and reduce the manufacturing cost.

[0027] The content of the present application will be described in detail below in combination with the drawings and specific embodiments.

[0028] Reference is made to Figure 1The embodiment provides an earphone assembly 10, which comprises earphones 20 and an earphone box 30, wherein the earphone box 30 is used for containing the earphones 20. The earphone box 30 comprises a shell 31, and the shell 31 comprises a box body 32 and a box cover 33. The box cover 33 is arranged on the box body 32 and can selectively open or close the box body 32. For example, the box cover 33 can be connected to the box body 32 in a hinged manner or can be detachably clamped on the box body 32, which is not limited herein.

[0029] The earphones 20 can comprise first earphones 21 and second earphones 22. The structure of the first earphones 21 can be adapted to the left ear of a human body, and the structure of the second earphones 22 can be adapted to the right ear of the human body. The first earphones 21 and the second earphones 22 are separated from each other in structure. The first earphones 21 and the second earphones 22 can be connected by a connecting line to form wired earphones, or can be configured to be connected in a wireless manner. The first earphones 21 and the second earphones 22 are identical in structure and mirror each other. In the embodiment, the first earphones 21 and the second earphones 22 are internally provided with a wireless communication module. The wireless communication module is used for wireless communication with a mobile intelligent terminal such as a mobile phone, a tablet computer or a smart watch. The wireless communication module can be a Bluetooth module, an infrared module or a ZigBee module. It can be understood that in other embodiments, the earphones 20 can also have one or more, which is not limited herein.

[0030] The box body 32 is provided with a containing groove (not shown) for containing the earphones 20 and an opening (not shown) in communication with the containing groove. It can be understood that the containing groove can be an integral whole, that is, for containing the first earphones 21 and the second earphones 22 in the earphones 20 at the same time. The containing groove can also be two independent spaces and be used for containing the first earphones 21 and the second earphones 22 respectively. It should be noted that the containing groove can contain all or part of the first earphones 21 or the second earphones 22. For example, in some embodiments, when the first earphones 21 are contained in the containing groove, the first earphones 21 can be completely located in the containing groove. In other embodiments, when the first earphones 21 are contained in the containing groove, the first earphones 21 can be partially located in the containing groove and partially extend out of the containing groove.

[0031] The opening is used for the earphones 20 to enter the containing groove. Therefore, the structure of the opening can be configured in a form suitable for the structure of the earphones 20, so as to facilitate a user to put the earphones 20 into the containing groove or take the earphones 20 out of the containing groove. In some embodiments, the earphones 20 can be contained in the containing groove in a vertical manner. At this time, the containing groove is configured in a substantially vertical arrangement form. The earphones 20 can also be contained in the containing groove in a horizontal manner. At this time, the containing groove is configured in a substantially horizontal arrangement form.

[0032] In this embodiment, only as an example, the receiving groove is used to receive part of the earphone 20, the box cover 33 is provided with a matching groove (not shown) matched with the receiving groove, and the matching groove is provided one by one with the receiving groove. When the earphone 20 is received in the receiving groove and the box cover 33 is closed, part of the earphone 20 is embedded in the matching groove. It can be understood that in some other embodiments, the box cover 33 can also not be provided with the matching groove, and the earphone 20 can be completely received in the receiving groove.

[0033] The shell 31 is also provided with a charging hole 34. In this embodiment, the charging hole 34 is provided on the box body 32, and a charging female socket interface is provided in the charging hole 34. In some other embodiments, the charging female socket interface can also be provided on the box cover 33, which is not limited herein. The box body 32 is also provided with a circuit board (not shown) provided with a solder pad.

[0034] Please refer to Figure 1 and Figure 2 , any one of the first earphone 21 and the second earphone 22 is provided with a battery 320, a power receiving circuit 330 and a power receiving contact 310. The battery 320 is electrically connected to the power receiving contact 310 through the power receiving circuit 330 to receive external power through the power receiving contact 310 and store it in the battery 320. Among them, the power receiving contact 310 can be arranged at any position of the shell 31 of the first earphone 21 and the second earphone 22, and for any one of the first earphone 21 and the second earphone 22, the number of power receiving contacts 310 includes but is not limited to one, and can also be multiple.

[0035] The box body 32 can also be provided with a storage battery 230 and a charging contact 210. The storage battery 230 and the charging contact 210 are electrically connected through the circuit board, and the storage battery 230 charges the earphone 20 through the charging contact 210. It can be understood that the charging contact 210 can be arranged in the accommodating groove in the box body 32. The number of charging contacts 210 can be an even number, and respectively correspond to the first earphone 21 and the second earphone 22, that is, the power receiving contact 310 and the charging contact 210 are matched with each other. When the first earphone 21 and / or the second earphone 22 is received in the accommodating groove, the power receiving contact 310 and the charging contact 210 can be electrically connected to each other, so that the storage battery 230 and the power receiving circuit 330 are conducted. When the earphone 20 is inserted into the accommodating groove, the earphone box 30 can charge the earphone 20. The earphone box 30 can also charge the storage battery 230 through an external charging device.

[0036] Please refer to Figure 1 , Figure 3 and Figure 4 , the box body 31 of the earphone box 30 is also provided with a charging female socket interface 100, which includes a surrounding shell 110, a tongue plate 120, a first row of terminals 130,Figure 6 (shown in the image) and the second row of terminals 140 ( Figure 7 As shown in the diagram, the housing 110 is disposed within the charging port 34, and the tongue plate 120, the first row of terminals 130, and the second row of terminals 140 are all located within the housing 110 and are used to connect with the charging socket 430. Figure 10 (As shown in the image) Connect for charging.

[0037] Specifically, the shell 110 forms a generally cylindrical structure, and the longitudinal interface of the area enclosed by the shell 110 is approximately oblong (waist-shaped), with the shell 110 forming a receiving cavity 112. For example... Figure 5 As shown, the receiving cavity 112 has an insertion port 113 for inserting a male connector and a mounting port 114 opposite to the insertion port 113. The insertion port 113 communicates with the charging port 34. When the male connector is inserted into the charging port 34, it can extend into the receiving cavity 112 through the insertion port 113. Further details can be found in the following sections. Figure 5 The housing 110 includes a housing 111 and a plurality of second pins 115. The housing 111 is used to form a receiving cavity 112, and the second pins 115 are connected to the housing 111 to fix the housing 111 inside the charging port 34.

[0038] The housing 111 includes a first housing 1111 and a second housing 1112, and a third housing 1113 and a fourth housing 1114, which are connected between the first housing 1111 and the second housing 1112. The first housing 1111, the second housing 1112, the third housing 1113, and the fourth housing 1114 form a receiving cavity 112. The first housing 1111 and the second housing 1112 are generally planar plate-like structures, while the third housing 1113 and the fourth housing 1114 are generally arc-shaped structures. The housing 111 as a whole has a flat structure, and the area of ​​the first housing 1111 and the second housing 1112 is larger than the area of ​​the third housing 1113 and the fourth housing 1114.

[0039] Insertion port 113 and mounting port 114 are formed at both ends of housing 111. Second pin 115 is connected to the end of housing 111 near mounting port 114 and extends away from housing 111. Second pin 115 can be integrally formed with housing 111 or welded to housing 111; no specific limitation is made here. Insertion port 113 has an insertion direction, which is approximately parallel to the central axis of insertion hole 34.

[0040] In this embodiment, please continue to refer to Figure 5The second pin 115 can include a first bent section 116 and a second bent section 117. The first bent section 116 is connected to the shell 111 and extends outwardly from the shell 111, i.e., extends in a direction away from the center of the shell 111. The second bent section 117 is connected to an end of the first bent section 116 away from the shell 111 and extends in a direction away from the insertion opening 113 after being bent relative to the first bent section 116. When installing the enclosure 110, the second bent section 117 can be fixed to the box body 32 by welding, insertion or adhesion. Preferably, the extending direction of the second bent section 117 is substantially parallel to the insertion direction of the insertion opening 113. This arrangement has the advantage that the second bent section 117 can be inserted into the fixing point by insertion when installing the enclosure 110, thereby improving the installation stability. In some embodiments, the second pin 115 can only include the second bent section 117, in which case the second pin 115 can be directly inserted into the solder pad on the circuit board.

[0041] Further, in order to make the enclosure 110 more stable when fixed, a plurality of second pins 115 can be arranged uniformly around the mounting opening 114. In this way, the enclosure 110 can be fixed in multiple directions during installation, thereby avoiding the enclosure 110 from shaking and causing poor contact during repeated insertion and removal of the male seat. As a more specific embodiment, the number of second pins 115 can be 6 or more, which is not limited herein.

[0042] In the first shell 1111 and the second shell 1112, any one of them can be connected to at least two second pins 115. In the third shell 1113 and the fourth shell 1114, any one of them can be connected to at least one second pin 115. For example, when the number of second pins 115 is 6, the first shell 1111 and the second shell 1112 can be connected to two second pins 115 respectively, and the third shell 1113 and the fourth shell 1114 can be connected to one second pin 115 respectively. The two second pins 115 connected to the first shell 1111 can be symmetrically arranged with the two second pins 115 connected to the second shell 1112, and the second pin 115 connected to the third shell 1113 can be symmetrically arranged with the second pin 115 connected to the fourth shell 1114. This arrangement makes the stress on the shell 111 more uniform and the stability higher during the fixing of the shell 111.

[0043] The second pin 115 can be connected to the outer wall or the inner wall of the shell 111, or can be directly connected to the end face of the shell 111 close to the mounting port 114, which is not specifically limited here. It should be noted that the shell 111 and the second pin 115 can be made of metal or alloy, for example, the shell 111 and the second pin 115 can be made of iron, aluminum, etc. In other embodiments, the shell 111 and the second pin 115 can also be made of high-strength resin plastic, which is not specifically limited here.

[0044] Please refer to Figure 6 and Figure 7 The tongue plate 120 is arranged in the accommodating cavity 112, and the tongue plate 120 has opposite first and second surfaces 123 and 124 located on opposite sides in the thickness direction of the tongue plate 120. The first surface 123 faces the first shell 1111, and the second surface 124 faces the second shell 1112. The first and second surfaces 123 and 124 can be substantially parallel to each other, and the first surface 123 can be substantially parallel to the first shell 1111, and the second surface 124 can be substantially parallel to the second shell 1112.

[0045] The tongue plate 120 includes an injection molded body 121 and a structural piece 122 embedded in the injection molded body 121. The structural piece 122 mainly serves to strengthen the strength of the tongue plate 120. The structural piece 122 can be a steel sheet, for example, and can be one or more pieces, which is not specifically limited here. The injection molded body 121 can be formed by plastic injection molding, and the injection molded body 121 is electrically insulating. Figure 8 As shown in FIG. 12, the injection molded body 121 includes first and second portions 1211 and 1212 connected to each other. The first portion 1211 is close to the insertion port 113 during assembly, and the second portion 1212 is close to the mounting port 114. The second portion 1212 protrudes from the first portion 1211 in the thickness direction of the first portion 1211 and is connected and fixed to the inner wall of the shell 111. The first and second surfaces 123 and 124 are formed on the first portion 1211, and the first surface 123 has a gap with the inner wall of the shell 111, and the second surface 124 has a gap with the inner wall of the shell 111.

[0046] The first and second rows of terminals 130 and 140 can be electrically connected to the circuit board arranged in the box body 32 to receive external power supply and charge the battery 230.

[0047] Please refer to Figure 6 and Figure 7The first row of terminals 130 is arranged on the first surface 123, and the first row of terminals 130 includes two ground terminals 131 (GND). The second row of terminals 140 is arranged on the second surface 124, and the second row of terminals 140 includes two positive terminals 141 (i.e., voltage pins VBUS), which are arranged staggered with respect to the two ground terminals 131. The staggered arrangement means that the positive terminals 141 and the ground terminals 131 are not opposite each other in the thickness direction of the tongue plate 120 (i.e., the direction perpendicular to the first surface 123 and the second surface 124). Since the ground terminals 131 and the positive terminals 141 are located on opposite side surfaces of the tongue plate 120, the spacing between the positive terminals 141 and the ground terminals 131 is increased, and is separated by the tongue plate 120. Therefore, even if liquid enters the charging hole 34, the liquid droplets are less likely to simultaneously contact the positive terminals 141 and the ground terminals 131, thereby reducing the risk of short circuiting.

[0048] Further, the first row of terminals 130 further includes a first differential signal terminal 133 (D+), a second differential signal terminal 134 (D-), and a first signal terminal 132 (CC1), and the second row of terminals 140 further includes a second signal terminal 142 (CC2). In summary, the charging female socket interface 100 in the embodiment is an 8-pin structure. As a more specific implementation, Table 1 shows the arrangement positions of the first row of terminals 130 and the second row of terminals 140 in the embodiment.

[0049] PIN ASSIGNMENTS:

[0050]

[0051] Table 1: Arrangement positions of the first row of terminals 130 and the second row of terminals 140

[0052] Wherein, A1-A12 represent the positions of the first surface 123 in sequence, and B1-B12 represent the positions of the first surface 123 in sequence.

[0053] As shown in Table 1, the two ground terminals 131 are located at positions A1 and A12 of the first surface 123, the first differential signal terminal 133 (D+) and the second differential signal terminal 134 (D-) are located at positions A6 and A7 of the first surface 123, respectively, the first signal terminal 132 (CC1) is located at position A5 of the first surface 123, the two positive terminals 141 (VBUS) are located at positions B9 and B4 of the second surface 124, respectively, and the second signal terminal 142 (CC2) is located at position B5 of the second surface 124. As can be seen from Table 1, the positive terminals 141 and the ground terminals 131 are staggered with respect to each other.

[0054] Since the two ground terminals 131 are located at the two side edge positions close to the first surface 123, and the two positive terminals 141 are located at the middle positions of the second surface 124, the spacing between the ground terminals 131 and the positive terminals 141 can be further enlarged, so as to achieve better short circuit prevention. In addition, the first differential signal terminal 133, the second differential signal terminal 134, and the first signal terminal 132 are located between the two ground terminals 131, so as to improve the isolation between the two ground terminals 131. The second signal terminal 142 is located between the two positive terminals 141, so as to improve the isolation between the two positive terminals 141. Of course, in other embodiments, the terminals can also be arranged in other ways.

[0055] The first row of terminals 130 and the second row of terminals 140 can be embedded in the first surface 123 and the second surface 124, and the first row of terminals 130 and the second row of terminals 140 are at least partially exposed, so that the male seat inserted into the insertion hole can be in electrical conduction with the first row of terminals 130 and the second row of terminals 140.

[0056] It should be noted that the specific arrangement position of the first row of terminals 130 and the second row of terminals 140 is not specifically limited in the present embodiment, and can be adjusted accordingly as needed.

[0057] Please refer to Figure 9 , each of the first row of terminals 130 and the second row of terminals 140 includes a first conductive part 151, a second conductive part 152, and a first pin 153. The first conductive part 151 is embedded in the tongue plate 120, and the second conductive part 152 is connected to the first conductive part 151 and extends out of the tongue plate 120 and is bent relative to the first conductive part 151. The second conductive part 152 can extend outwards of the housing 111, i.e., in a direction away from the central axis of the housing 111, so as to avoid overcrowding between the terminals. The first pin 153 is connected to an end of the second conductive part 152 away from the first conductive part 151, and is used to connect with the solder pad in the earphone box. The extension direction of the first pin 153 is substantially the same as the insertion direction of the insertion hole 113. In this way, when the charging female seat interface 100 is installed, the first pin 153 can be directly inserted and welded with the solder pad, and compared with the patch welding, the welding point of the insertion welding surrounds the entire first pin 153, so that the stability is higher and the solder tin cracking is avoided. In addition, the welding point of the insertion welding is smaller, so that the spacing between the welding points on the solder pad can be enlarged, and the short circuit risk caused by tin migration during welding can be reduced.

[0058] In some embodiments, the first row of terminals 130 and the second row of terminals 140 and the tongue plate 120 can be combined by one-piece injection molding. Since the present embodiment only uses an 8-pin structure, in the manufacturing process, the 8-pin can be formed by one-time die casting, and then the tongue plate 120 is injection molded together with the structure piece 122. The entire preparation process has fewer procedures and relatively low cost.

[0059] The charging female socket interface 100 provided by the present embodiment increases the spacing between the positive terminal 141 and the negative terminal by arranging the positive terminal 141 and the ground terminal 131 on the opposite first surface 123 and second surface 124 of the tongue plate 120, respectively, and staggering the positive terminal 141 and the ground terminal 131 with each other. This avoids short circuit and burnout between the positive terminal 141 and the ground terminal 131 due to liquid ingress. At the same time, by reducing the number of pins, the charging performance of the earphone assembly is not affected, the process is saved, and the production cost is reduced.

[0060] Referring to Figure 10 The present embodiment also provides a charging connection line 400, which includes a charging male socket 430, a wire 410, and a connector 420. The connector 420 is used to connect with an external power supply, such as a household power supply (220V), or to connect with other electronic devices, such as a USB interface on a computer, a power bank, or a power adapter, etc. The connector 420 can be configured in multiple forms, such as a USB connector, a Micro USB connector, a Type-c connector, etc. The connector 420 can also be directly configured as an adapter structure, which is not limited herein. The wire 410 can be set to any length and covered by an outer layer made of plastic insulation.

[0061] The charging male socket 430 can be adapted to the charging female socket interface 100 described above, and can be inserted into the charging hole 34 and the insertion port 113, and electrically connected with the first row of terminals 130 and the second row of terminals 140, to charge the earphone box 30.

[0062] Specifically, referring to Figure 11The charging male base 430 comprises an annular shell 431 and a third row of terminals 440 and a fourth row of terminals 450 arranged on the inner wall of the annular shell 431, wherein the structure of the annular shell 431 is matched with the structure of the shell body 111, so that the annular shell 431 can be inserted into the accommodating cavity 112 surrounded by the shell body 111 through the insertion opening 113, and when the annular shell 431 is inserted into the accommodating cavity 112, the annular shell 431 can be in interference with the shell body 111, so that the charging male base 430 can be relatively fixed with the shell body 111. The annular shell 431 surrounds an inner cavity 432, when the tongue plate 120 is inserted into the inner cavity 432, the first inner wall 433 can be in close contact with the first surface 123, and the second inner wall 434 can be in close contact with the second surface 124.

[0063] The third row of terminals 440 and the fourth row of terminals 450 can be electrically connected with the wire 410 to receive external power supply. The third row of terminals 440 is arranged on the first inner wall 433, and the third row of terminals 440 comprises two ground terminals 441 (GND). The fourth row of terminals 450 is arranged on the second inner wall 434, and the fourth row of terminals 450 comprises two positive terminals 451 (i.e. voltage pins VBUS), and the two positive terminals 451 and the two ground terminals 441 are arranged staggered with each other, which means that the positive terminals 451 and the ground terminals 441 are not opposite to each other in the thickness direction of the annular shell 431 (i.e. the direction perpendicular to the first inner wall 433 and the second inner wall 434). Since the ground terminals 441 and the positive terminals 451 are located on the opposite inner walls of the annular shell 431, the distance between the positive terminals 451 and the ground terminals 441 is increased, so that even if the inner cavity 432 is filled with liquid, the liquid drops are not easy to contact the positive terminals 451 and the ground terminals 441 at the same time to form a short circuit phenomenon. Moreover, since the ground terminals 441 and the positive terminals 451 are staggered with each other, the risk of short circuit is further reduced.

[0064] Further, the third row of terminals 440 further comprises a first differential signal terminal 443 (D+), a second differential signal terminal 444 (D-) and a first signal terminal 442 (CC1), and the fourth row of terminals 450 further comprises a second signal terminal 452 (CC2). It can be understood that the positions of the third row of terminals 440 and the fourth row of terminals 450 on the charging male base 430 are arranged in the same order, which can be referred to the foregoing content and will not be limited here.

[0065] When the ring-shaped shell 431 is inserted into the accommodating cavity 112, the first row of terminals 130 and the third row of terminals 440 are in corresponding contact and conductive, and the second row of terminals 140 and the fourth row of terminals 450 are in corresponding contact and conductive. The above-mentioned charging male seat 430 and the charging connecting line 400 can be matched with the charging female seat interface 100 and charged, which can also achieve the purposes of reducing the risk of short-circuit burning and reducing the manufacturing cost.

[0066] It should be noted that in the present application, the descriptions involving "first", "second", "third", "fourth" are only used for differentiation and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features.

[0067] The above only is the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
