Detailed Description

The following is a preferred embodiment of the present application, and it should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present application, and these improvements and modifications are also considered as the protection scope of the present application.

Before the technical scheme of the application is introduced, the technical problems of the related art are further described in detail.

With the development of science and technology and the progress of the times, the internet and the mobile communication network provide a huge amount of application functions. The user can use the electronic device not only for traditional applications, such as answering or making a call using a mobile phone. Meanwhile, the user can also use the electronic equipment to browse a webpage, browse pictures, play videos, play games and the like.

Therefore, the frequency of using the electronic device by the user is increasing, but the electric quantity of the battery in the electronic device is greatly consumed, so that the electronic device needs to be charged frequently, for a plurality of times, even for 2-3 times in a day. The electronic equipment transmits voltage by using a power pin in the charging interface, so that energy can be charged for a battery of the electronic equipment, or energy can be directly provided for the electronic equipment. However, at present, the charging speed of the electronic device is slow due to various reasons, and the time required for charging the electronic device once is long, so that the requirements of users cannot be met.

For example, the cross-sectional area of the power pin of the current charging interface is 0.1mm ² -1mm ² The total cross-sectional area of all the charging pins occupies less than 2% (about 1.7%) of the cross-sectional area of the accommodating space of the housing, and the cross-sectional area of each charging pin occupies less than 1% of the cross-sectional area of the accommodating space. Therefore, the appearance of the current charging pin is thin and strip-shaped, so that the cross section area of the current charging pin is small, the overcurrent capacity is weak, the transmission speed of current is reduced, and the charging speed is reduced.

Based on this, the application provides a charging interface, can effectively improve the speed of charging. Referring to fig. 1 to 7 together, fig. 1 is a schematic perspective view of a charging interface according to an embodiment of the present application. Fig. 2 is a schematic perspective view of another view angle of the charging interface shown in fig. 1. Fig. 3 is an exploded view of the charging interface shown in fig. 1. Fig. 4 isbase:Sub>A schematic cross-sectional view of the charging interface shown in fig. 1 alongbase:Sub>A directionbase:Sub>A-base:Sub>A. Fig. 5 is a schematic cross-sectional view of the charging interface shown in fig. 1 along the direction B-B. Fig. 6 is a schematic cross-sectional view of the power pin and the housing including only a bottom wall according to an embodiment of the present application. Fig. 7 is a schematic cross-sectional view of the power pin and the housing including only the first sidewall according to an embodiment of the present application.

The present embodiment provides a charging interface 1, which specifically includes a housing 10 and a plurality of power pins 20 arranged at intervals. Wherein the housing 10 comprises a bottom wall 11 and/or a first side wall 12; when the housing 10 includes the bottom wall 11 and the first side wall 12, the first side wall 12 is bent to connect the periphery of the bottom wall 11. A plurality of power pins 20 are disposed at intervals, and the power pins 20 are mounted on at least one of the bottom wall 11 and the first side wall 12. Wherein, in the axial direction perpendicular to the housing 10, the cross-sectional area of each power supply pin 20 is 18mm ² -60mm ² 。

The charging interface 1 provided in the present embodiment is applicable to various devices, for example, to an electronic device 3 that needs to be charged, or to a power adapter 2 that provides a charging function, or the like. In fact, as long as the device of the charging interface 1 provided in the present embodiment is applied, the charging interface 1 and the corresponding device should belong to the protection scope of the present application.

The charging interface 1 is composed of a plurality of structural members, and in this embodiment, mainly includes a housing 10 and a power pin 20. However, this does not mean that charging interface 1 includes only two parts, namely housing 10 and power pin 20, and this embodiment means that only housing 10 and power pin 20 need to be used to solve the above-mentioned technical problem. In this and other embodiments, charging interface 1 may also comprise other structural elements, such as data pin 30. Next, the present embodiment will describe the housing 10 and the power pin 20 in sequence and in detail.

The housing 10 serves as a plug main body of the charging interface 1, and is mainly used for installing and protecting other structural members, and the charging interface 1 is integrally installed on the other structural members by the aid of the housing 10. The housing 10 is typically made of an insulating material, so that it has good insulation properties and prevents short-circuiting with other parts of the charging interface 1. The present embodiment does not limit the specific material of the case 10 as long as the insulating function can be achieved.

The housing 10 includes a bottom wall 11 and/or a first side wall 12, in other words, the housing 10 may include only the bottom wall 11 in one embodiment, the housing 10 may include only the first side wall 12 in another embodiment, and the housing 10 may include both the bottom wall 11 and the first side wall 12 in other embodiments. When the housing includes the first sidewall 12 or the housing 10 includes the bottom wall 11 and the first sidewall 12, the housing 10 has the receiving space 13. In other words, the first sidewall 12 may enclose the accommodating space 13, or the bottom wall 11 and the first sidewall together enclose the accommodating space 13.

When the housing 10 includes both the bottom wall 11 and the first side wall 12, the first side wall 12 is bent and connected to the entire periphery of the bottom wall 11, that is, a space surrounded by the first side wall 12 for 360 ° is an accommodating space 13, and the accommodating space 13 has an opening only on a side of the first side wall 12 away from the bottom wall 11. It can also be understood that the first sidewall 12 has a first outer side 121 and a first inner side 122, which are opposite to each other, and the first outer side 121 is farther from the accommodating space 13 than the first inner side 122. First outer side 121 forms an external appearance surface of charging interface 1, and first inner side 122 and bottom wall 11 together enclose to form receiving space 13.

In addition, the present embodiment refers to in the axial direction perpendicular to the housing 10 (as shown by O in fig. 1-2) in the extending direction perpendicular to the first side wall 12, in other words, in the height direction perpendicular to the first side wall 12. It is also understood that the bottom wall 11 has a connecting surface 110 (shown in fig. 4) bent to connect with the first sidewall 12, in a direction parallel to the connecting surface 110. It is expected that the shape of the receiving space 13 is fixed after the first sidewall 12 is bent to connect the periphery of the bottom wall 11. The sectional shape of the housing space 13 in the axial direction perpendicular to the housing 10 is also fixed, and therefore the sectional area of the housing space 13 is also fixed. It is to be noted that, unless otherwise specified, the sectional shape and the sectional area mentioned below in the present application each refer to a section in the axial direction perpendicular to the housing 10. Specifically, the cross section referred to hereinafter in the present application is a cross section taken from the middle of the first side wall 12 in the direction perpendicular to the axial direction of the first side wall 12, at a position shown by the section line B-B in fig. 1.

Alternatively, the sectional shape of the housing space 13 is not limited in the present embodiment, and for example, the present embodiment is schematically described only in a case where the sectional shape of the housing space 13 is a circle and the entire housing space 13 is a cylinder. In other embodiments, the cross-sectional shape of the housing space 13 may be a racetrack shape, an oval shape, a rectangular shape, or other shapes.

Alternatively, the bottom wall 11 and the first side wall 12 may be a single-piece structure or a split structure. When the bottom wall 11 and the first side wall 12 are of an integral structure, which means that the bottom wall 11 and the first side wall 12 are prepared through a single process, both the bottom wall 11 and the first side wall 12 are used for installing the power pins 20. However, to facilitate understanding, different parts of the housing 10 have been named differently by man. When the bottom wall 11 and the first side wall 12 are of a split structure, it means that the bottom wall 11 and the first side wall 12 are prepared through different processes and then connected together by various methods (e.g., welding, bonding, etc.). In one embodiment, both the bottom wall 11 and the first side wall 12 may be used for mounting the power pins 20. In other embodiments, the power pin 20 can be mounted only by the first sidewall 12, and the bottom wall 11 can perform other functions, such as turning on the power pin 20.

Alternatively, the present embodiment does not limit the size parameters of the bottom wall 11 and the first side wall 12, for example, the length, width, and height of the bottom wall 11 and the first side wall 12. The size of the bottom wall 11 and the first side wall 12, and even the size of the receiving space 13, can be adjusted according to the size of the device to which the charging interface 1 is actually applied.

The power supply pin 20 may also be referred to as an overcurrent terminal (VBus), and is mainly used to pass a current. Since the charging interface 1 can be applied to the electronic device 3 that needs to be charged and can also be applied to the power adapter 2 that provides a charging function, the function of the power pin 20 of the charging interface 1 is slightly different. Wherein the power pin 20 on the electronic device 3 is used to receive the voltage from the power adapter 2 for eventual transmission to the battery 90 within the electronic device 3. The power pin 20 of the power adapter 2 is used for receiving the voltage from the socket, transmitting the voltage to the power pin 20 of the charging interface 1 of the electronic device 3, and finally transmitting the voltage to the battery 90 in the electronic device 3.

The present embodiment includes a plurality of power pins 20. Wherein the plurality of power pins 20 includes at least one positive power pin 20 and at least one negative power pin 20. The number of supply pins 20 is at least two. The number of the positive power pins 20 and the number of the negative power pins 20 are not limited herein. In addition, any two adjacent power pins 20, especially the positive power pin 20 and the negative power pin 20, need to be spaced to prevent short circuit.

The material of the power pin 20 is usually conductive so as to effectively transmit current, and the specific material of the power pin 20 is not limited in this embodiment as long as the conductive function can be achieved. The power pin 20 is mounted on the housing 10, the housing 10 can be used to stably mount the power pin 20, and the housing 10 can be used to protect the power pin 20.

Alternatively, in one embodiment, power pins 20 may be mounted to bottom wall 11, for example, as shown in fig. 6, housing 10 may include only bottom wall 11, and power pins 20 may be mounted to bottom wall 11. Alternatively, as shown in fig. 4, the housing 10 includes both the bottom wall 11 and the first side wall 12, and the power pin 20 is connected to only the bottom wall 11 and spaced apart from the first side wall 12, and at this time, only the bottom wall 11 is used to fix and mount the power pin 20.

In another embodiment, the power pin 20 can also be mounted on the first sidewall 12, for example, as shown in fig. 7, the housing 10 includes only the first sidewall 12, and the power pin 20 is mounted on the first sidewall 12. Alternatively, as shown in fig. 4, the housing 10 includes both the bottom wall 11 and the first side wall 12, the power pins 20 are connected to only the first side wall 12 and spaced apart from the bottom wall 11, and at this time, only the first side wall 12 is used to fix and mount the power pins 20. For another example, the power pin 20 may connect the bottom wall 11 and the first side wall 12 of the split structure, but only the first side wall 12 is used for fixing and installing the power pin 20. In this case, the bottom wall 11 may be a circuit board, and the connection of the power pins 20 through the bottom wall 11 plays a role of conducting the power pins 20, but does not play a role of installation.

In another embodiment, the power pins 20 may also be mounted on the bottom wall 11 and the first side wall 12 simultaneously, for example, the power pins 20 are connected to the bottom wall 11 and the first side wall 12 simultaneously, and the bottom wall 11 and the first side wall 12 are used to fix and mount the power pins 20. In other embodiments, power pin 20 may even be mounted to other components of housing 10.

Since the power pins 20 need to be electrically connected to the circuit board to achieve the matching with the circuit board, no matter where the power pins 20 are installed on the housing 10, one end of the power pins 20 is electrically connected to the circuit board. Alternatively, in one embodiment, one end of the power pin 20 may extend through the bottom wall 11 so as to protrude from the bottom wall 11. In another embodiment, one end of the power pin 20 may extend from the outer periphery of the bottom wall 11 so as to protrude from the bottom wall 11. And because the application equipment of the charging interface 1 is different, the matching relationship between the power pin 20 and the circuit board is also different. For example, when the charging interface 1 is applied to the electronic device 3, the charging interface 1 transmits the received voltage to the circuit board for processing, and then transmits the voltage to the battery 90 through the circuit board for charging. When the charging interface 1 is applied to the power adapter 2, the circuit board receives the voltage transmitted from the socket by the pin 50, and the voltage is transmitted to the power pin 20 after being processed by the circuit board.

As for the positional relationship of the power pin 20 and the receiving space 13, in one embodiment, a portion of the power pin 20 may be located in the receiving space 13. In another embodiment, the power pin 20 may be located outside the receiving space 13. Likewise, the opposite end of the power pin 20 may be located inside the receiving space 13 in one embodiment, and may be located outside the receiving space 13 in another embodiment.

In addition, since the power pin 20 is a rod-shaped member having a certain length, the extending direction of the housing 10 mentioned above can be also understood as the extending direction of the length of the power pin 20.

As can be seen from the above, the cross-sectional area of the power supply pin 20 in the related art is only 0.1mm ² -1mm ² The smaller cross-sectional area results in a slower current transfer rate. The present embodiment can make the cross-sectional area of each power pin 20 18mm ² -60mm ² (the area shown by the crossed diagonal fill lines in power pin 20 in fig. 5), the cross-sectional area of power pin 20 is increased by more than 10 times compared with the cross-sectional area of power pin 20 in the related art, and the cross-sectional area of power pin 20 is greatly increased. The increase of the cross-sectional area of the power supply pin 20 can increase the load capacity of current passing in unit time, so that the transmission speed of the current is increased, namely, the overcurrent capacity is increased, and the transmission speed of the current is increased by more than 10 times; the charging interface 1 has a quick charging function, and the charging efficiency of the battery 90 of the electronic device 3 is improved.

How to increase the cross-sectional area of the power pin 20 to the size provided by the present embodiment can be achieved by changing the power leadThe structure, position, shape, etc. of the foot 20, and this embodiment will be described in detail below. Optionally, each power pin 20 has a cross-sectional area of 18mm ² -22mm ² ，25mm ² -30mm ² And 50mm ² -60mm ² 。

Referring to fig. 5 again, in the present embodiment, when the housing 10 includes the first sidewall 12 or the housing 10 includes the bottom wall 11 and the first sidewall 12, the housing 10 has an accommodating space 13, and a cross-sectional area of each power pin 20 in an axial direction perpendicular to the housing 10 occupies 5% to 20% of a cross-sectional area of the accommodating space 13. Alternatively, when the housing 10 includes the bottom wall 11, the bottom wall 11 has a connection surface 110 for mounting the power pins 20, and the cross-sectional area of each power pin 20 occupies 5% to 20% of the area of the connection surface 110.

As can be seen from the above, the receiving space 13 has a constant cross-sectional area in the direction perpendicular to the axial direction of the housing 10, and the power supply pin 20 also has a corresponding cross-section. In the case where the cross-sectional area of the receiving space 13 of the related art is the same as that of the present application, the cross-sectional area of each charging pin of the related art occupies less than 1% of the cross-sectional area of the receiving space 13. In the present embodiment, the cross-sectional area of each power pin 20 may occupy 5% to 20% of the cross-sectional area of the accommodating space 13. In the present embodiment, the cross-sectional area of the power pin 20 is increased without changing the cross-sectional area of the accommodating space 13, in other words, the power pin 20 is made thicker, thereby increasing the throughput of current per unit time and increasing the charging efficiency. Alternatively, as shown in fig. 6, when the housing includes only the bottom wall 11, the bottom wall 11 has a connection surface 110 for mounting the power pins 20, and the cross-sectional area of the power pins 20 is not compared with the cross-sectional area of the receiving space 13, but compared with the area of the connection surface 110, that is, the cross-sectional area of each power pin 20 occupies 5% to 20% of the area of the connection surface 110.

Alternatively, the cross-sectional shape of the housing space 13 is schematically illustrated as a circle in the present embodiment, and the radius of the housing space 13 is 10mm.

Optionally, the cross-sectional area of each power pin 20 occupies 5.73% -19.11% of the cross-sectional area of the receiving space 13. Further optionally, the cross-sectional area of each power pin 20 accounts for 5.73% -7.01%,7.96% -9.55%, and 15.92% -19.11% of the cross-sectional area of the receiving space 13.

Alternatively, the shape of the connection surface 110 is illustrated schematically as a circle, and the radius of the connection surface 110 is 10mm.

Optionally, the cross-sectional area of each power pin 20 occupies 5.73-19.11% of the area of the connection face 110. Further alternatively, the cross-sectional area of each power pin 20 occupies 5.73% -7.01%,7.96% -9.55%, and 15.92% -19.11% of the area of the connection face 110.

Referring to fig. 1 to 7 again, in this embodiment, when the housing 10 includes the first sidewall 12 or the housing 10 includes the bottom wall 11 and the first sidewall 12, the housing 10 has an accommodating space 13, the housing 10 further includes a second sidewall 14, the second sidewall 14 is disposed in the accommodating space 13, the plurality of power pins 20 include at least one first power pin 21 and at least one second power pin 22, and the first power pin 21 and the second power pin 22 have opposite polarities and are disposed at intervals; the first power pin 21 is mounted on the first sidewall 12, and the second power pin 22 is mounted on the second sidewall 14.

The receiving space 13, the first power pin 21, and the second power pin 22 are described above in detail, and the detailed description of the embodiment is omitted here. The present embodiment is only schematically described with the case 10 including the bottom wall 11 and the first side wall 12. In the present embodiment, the housing 10 further includes a second sidewall 14 besides the bottom wall 11 and the first sidewall 12, the second sidewall 14 is also connected to the bottom wall 11 in a bending manner, and the second sidewall 14 is disposed in the accommodating space 13. In other words, the first sidewall 12 is disposed corresponding to the outer periphery of the second sidewall 14. Such that the first side wall 12 is enclosed to form a large ring shape and the second side wall 14 is enclosed to form a small ring shape. Alternatively, the second sidewall 14 and the bottom wall 11 may enclose a receiving space 15, and the receiving space 15 is actually a part of the receiving space 13. In this embodiment, the first power pin 21 may be disposed on the first sidewall 12, and the second power pin 22 may be disposed on the second sidewall 14. The two power pins 20 are respectively installed on the first sidewall 12 and the second sidewall 14, so that the difficulty of installing the first power pin 21 and the second power pin 22 can be reduced.

Alternatively, the cross-sectional shapes of the first power pin 21 and the second power pin 22 in the direction perpendicular to the axial direction of the housing 10 are annular.

Alternatively, the second side wall 14 and the first side wall 12 and the bottom wall 11 may be a unitary structure, i.e., the first side wall 12, the second side wall 14, and the bottom wall 11 are prepared by the same process, but for ease of understanding, different parts of the housing 10 are named differently by human beings. Or the second side wall 14 and the first side wall 12 and the bottom wall 11 may be a split structure, that is, the first side wall 12, the second side wall 14, and the bottom wall 11 are separately prepared through different processes and then connected together through various methods (e.g., welding, bonding, etc.). Or the second side wall 14, the first side wall 12 and the bottom wall 11 are partially of a split structure and partially of an integral structure, that is, some of the three components are prepared through the same process, while the rest are prepared through different processes and then connected together through various methods (such as welding, bonding and the like).

Referring to fig. 5 again, in the present embodiment, the first sidewall 12 has a first outer side 121 and a first inner side 122 that are opposite to each other, and the first outer side 121 is far away from the accommodating space 13 than the first inner side 122; the second sidewall 14 has a second outer side 141 and a second inner side 142 opposite to each other, and the second outer side 141 is closer to the first inner side 122 than the second inner side 142; the charging interface 1 satisfies at least one of the following conditions:

the first power pin 21 is disposed on at least one of the first outer side 121 and the first inner side 122. The second power pin 22 is disposed on at least one of the second outer side 141 and the second inner side 142.

The first outer side 121 and the first inner side 122 of the first sidewall 12 are described in detail above, and the description of the embodiment is omitted here. The second side wall 14 likewise has two oppositely disposed side faces: a second outer side 141 and a second inner side 142. The second outer side 141 and the second inner side 142 are disposed in the accommodating space 13. The second outer side surface 141 is closer to the first inner side surface 122 than the second inner side surface 142, in other words, the second outer side surface 141 is farther away from the accommodating space than the second inner side surface 142.

It has been mentioned above that the first power pin 21 is mounted on the first sidewall 12, and the second power pin 22 is mounted on the second sidewall 14. As to the specific locations of the first power pin 21 and the second power pin 22, this embodiment provides various implementations. Specifically, the first power pin 21 may be disposed on at least one of the first outer side surface 121 and the first inner side surface 122. For example, the first power pin 21 can be disposed on the first outer side 121, or the first power pin 21 can be disposed on the first inner side 122, or the first power pin 21 can be disposed on both the first outer side 121 and the first inner side 122. Similarly, the second power pin 22 may be disposed on at least one of the second outer side 141 and the second inner side 142. For example, the second power pin 22 may be disposed on the second outer side 141, or the second power pin 22 may be disposed on the second inner side 142, or the second power pin 22 may be disposed on both the second outer side 141 and the second inner side 142. As shown in fig. 5, the present embodiment is schematically illustrated by only the first power supply pin 21 being provided on the first inner side surface 122 and the second power supply pin 22 being provided on the second inner side surface 142.

Alternatively, the power pins 20 disposed in the accommodating space 13 may protrude from the bottom wall 11 by penetrating through the bottom wall 11, and the power pins 20 disposed outside the accommodating space 13 may extend from the outer periphery of the bottom wall 11 to the outside of the bottom wall 11 and protrude from the bottom wall 11.

To achieve a cross-sectional area of 18mm per supply pin 20 ² -60mm ² The power supply pin 20 occupies 5-20% of the cross-sectional area of the accommodating space 13, and the application provides a plurality of types of power supply pinsIn particular embodiments where the power pin 20 is mated with the housing 10. The following description will be made one by one.

Referring to fig. 8-9 together, fig. 8 is a schematic cross-sectional view of a charging interface along a direction B-B according to another embodiment of the present application. FIG. 9 is a schematic cross-sectional view of a charging interface along the direction B-B according to another embodiment of the present application. In this embodiment, a portion of the power pin 20 is mounted on the first sidewall 12, and the cross-sectional shape of the power pin 20 is annular or fan-shaped in the axial direction perpendicular to the housing 10.

In the first embodiment, a portion of the power pin 20 is mounted on the first sidewall 12, i.e., the power pin 20 is connected to the first sidewall 12 in an assembling manner. The rest of the power pins 20 are not mounted on the first sidewall 12, and the rest of the power pins may protrude from the bottom wall 11 for electrically connecting the circuit board, and may also be used for other functions. With respect to the relationship between the power pin 20 and the bottom wall 11, the power pin 20 may be mounted on the bottom wall 11 in one embodiment, or the power pin 20 may not be mounted on the bottom wall 11 in another embodiment. Since the first sidewall 12 is connected to the periphery of the bottom wall 11 in a bending manner, the first sidewall 12 can be formed in a ring shape. The power supply pin 20 is mounted on the first sidewall 12 such that the cross-sectional shape of the power supply pin 20 is a ring or a portion of a ring in a direction perpendicular to the axial direction of the housing 10. As shown in fig. 8, when each power pin 20 is surrounded by a portion of the first sidewall 12, the cross-sectional shape of each power pin 20 is a sector, which is a part of a ring. As shown in fig. 9, when each power pin 20 is disposed around the entire first sidewall 12, the cross-sectional shape of each power pin 20 is circular. Therefore, the space of the charging interface 1 can be fully utilized, so that the size of the charging interface 1 cannot be excessively increased or too much space of the accommodating space 13 is occupied by the power pin 20 on the basis of increasing the cross-sectional area.

Referring to fig. 8 again, in the present embodiment, when the housing 10 includes the first side wall 12 or the housing 10 includes the bottom wall 11 and the first side wall 12, the plurality of power pins 20 include at least one first power pin 21 and at least one second power pin 22, and the polarities of the first power pin 21 and the second power pin 22 are opposite and are spaced apart; the first power pin 21 and the second power pin 22 are both mounted on the same side of the first sidewall 12, the first power pin 21 is mounted on a portion of the first sidewall 12, and the second power pin 22 is mounted on a portion of the first sidewall 12.

The plurality of power pins 20 includes two types of power pins 20: a first power pin 21 and a second power pin 22. The number of each power supply pin 20 is at least one, and the polarities of the two power supply pins 20 are opposite. The first power pin 21 may be one of the positive power pin 20 and the negative power pin 20, and the second power pin 22 may be the other of the positive power pin 20 and the negative power pin 20. For example, when the first power pin 21 is the positive power pin 20, the second power pin 22 is the negative power pin 20. When the first power pin 21 is the negative power pin 20, the second power pin 22 is the positive power pin 20. The two power pins 20 are spaced apart to prevent shorting.

In this embodiment, the first power pin 21 and the second power pin 22 can be disposed on the same side of the first sidewall 12, for example, the first power pin 21 and the second power pin 22 are disposed on the first outer side 121 of the first sidewall 12 together, so that the size of the accommodating space 13 is not occupied and the arrangement of the structural members in the accommodating space 13 is not affected. Alternatively, the first power pin 21 and the second power pin 22 are commonly disposed on the first inner side 122 of the first sidewall 12, and at this time, the first sidewall 12 of the housing 10 can be utilized to effectively protect the first power pin 21 and the second power pin 22. In addition, since the first power pin 21 and the second power pin 22 are disposed on the same side of the first sidewall 12, both the first power pin 21 and the second power pin 22 are disposed on only a portion of the first sidewall 12. This allows the cross-sectional area size to be achieved using only one side surface of the first side wall 12.

Alternatively, when the first power pin 21 and the second power pin 22 are arranged at intervals along the circumferential direction of the housing 10, the cross-sectional shapes of the first power pin 21 and the second power pin 22 are annular portions. When the first power pin 21 and the second power pin 22 are disposed at intervals along the axial direction of the housing 10, the cross-sectional shapes of the first power pin 21 and the second power pin 22 are annular.

Optionally, when the first power pin 21 and the second power pin 22 are disposed on the first outer side 121, the first power pin 21 and the second power pin 22 protrude from the bottom wall 11 through a periphery of the bottom wall 11. When the first power pin 21 and the second power pin 22 are disposed on the first inner side surface 122, the first power pin 21 and the second power pin 22 penetrate the bottom wall 11 and protrude from the bottom wall 11.

Referring to fig. 9 again, in this embodiment, when the housing 10 includes the first side wall 12 or the housing 10 includes the bottom wall 11 and the first side wall 12, the housing 10 has a receiving space 13, the plurality of power pins 20 includes at least one first power pin 21 and at least one second power pin 22, and the first power pin 21 and the second power pin 22 have opposite polarities and are disposed at intervals; the first power pin 21 and the second power pin 22 are mounted on opposite sides of the first sidewall 12, and the first power pin 21 is closer to the accommodating space 13 than the second power pin 22.

The accommodating space 13, the first power pin 21, and the second power pin 22 are described in detail above, and the detailed description of the embodiment is omitted here. In this embodiment, the first power pin 21 and the second power pin 22 can be disposed on opposite sides of the first sidewall 12, such that the first power pin 21 is disposed on the first inner side 122 and the second power pin 22 is disposed on the first outer side 121. In other words, the first power pin 21 is disposed in the accommodating space 13, and the second power pin 22 is disposed outside the accommodating space 13, so that the first power pin 21 is closer to the accommodating space 13 than the second power pin 22. This can further increase the cross-sectional area or height of the first power pin 21 and the second power pin 22, further increasing the speed of current transmission, and thus increasing the charging speed.

In addition, the first power pin 21 disposed in the accommodating space 13 may penetrate through the bottom wall 11 and protrude from the bottom wall 11, and the second power pin 22 disposed outside the accommodating space 13 may extend from the periphery of the bottom wall 11 and protrude from the bottom wall 11.

Referring to fig. 10, fig. 10 is a schematic cross-sectional view of a charging interface along a direction B-B according to another embodiment of the present application. In this embodiment, the housing 10 further includes a third sidewall 16, the third sidewall 16 is disposed in the accommodating space 13, and the second power pin 22 is further mounted on the third sidewall 16; wherein the total area of the cross section of the at least one first power pin 21 is the same as the total area of the cross section of the at least one second power pin 22 in the axial direction perpendicular to the housing 10.

In the present embodiment, the housing 10 includes a third side wall 16 in addition to the bottom wall 11, the first side wall 12, and the second side wall 14, and the third side wall 16 is provided in the accommodating space 13. In other words, the first sidewall 12 is disposed corresponding to the outer peripheral edge of the third sidewall 16. Such that the first side wall 12 is enclosed to form a large ring shape and the third side wall 16 is enclosed to form a small ring shape. Optionally, the third sidewall 16 is disposed in the receiving space 15, that is, the second sidewall 14 is disposed corresponding to the outer periphery of the third sidewall 16. Thus, the cross-sections of the first, second and

third sidewalls

12, 14, 16 form a large, medium and small ring shape, respectively. The first power supply pin 21 is provided on the first side wall 12 of the large ring shape, the second power supply pin 22 is provided on the second side wall 14 of the middle ring shape, and the third side wall 16 of the small ring shape.

The present embodiment may make the total area of the cross-section of the at least one first power pin 21 the same as the total area of the cross-section of the at least one second power pin 22. In other words, the second power pin 22 is mounted by two annular sidewalls with a slightly smaller radius, and the first power pin 21 is mounted by an annular sidewall with a slightly larger radius. So that the sum of the cross-sectional areas of its two small second supply pins 22 equals the cross-sectional area of one large first supply pin 21. Thus, the cross-sectional areas of the positive power pin 20 and the negative power pin 20 are equal, thereby further increasing the charging speed.

Alternatively, the first side wall 12, the second side wall 14, the third side wall 16, and the bottom wall 11 may be a unitary structure, i.e., the first side wall 12, the second side wall 14, the third side wall 16, and the bottom wall 11 are prepared by the same process, but different parts of the casing 10 are named differently for ease of understanding. Alternatively, the first side wall 12, the second side wall 14, the third side wall 16, and the bottom wall 11 may be a split structure, that is, the first side wall 12, the second side wall 14, the third side wall 16, and the bottom wall 11 are separately prepared through different processes and then connected together by various methods (e.g., welding, bonding, etc.). Or the first side wall 12, the second side wall 14, the third side wall 16, and the bottom wall 11 are partially split structures and partially integrated structures, that is, some of the four components are prepared through the same process, while the rest are prepared through different processes, and then are connected together through various methods (e.g., welding, bonding, etc.).

Referring to fig. 11, fig. 11 isbase:Sub>A schematic cross-sectional view ofbase:Sub>A charging interface alongbase:Sub>A directionbase:Sub>A-base:Sub>A according to another embodiment of the present disclosure. In this embodiment, when the housing 10 includes the bottom wall 11 and the first side wall 12, the power pin 20 includes a first portion 201, and a second portion 202 and a third portion 203 connected to the first portion 201, the second portion 202 and the third portion 203 are disposed on two opposite sides of the first portion 201, the first portion 201 is mounted on the first side wall 12, the second portion 202 protrudes from the bottom wall 11, and the third portion 203 is bent to connect the first portion 201 and connects a side of the first side wall 12 away from the bottom wall 11.

The above describes various arrangements of the power pins 20 and the side walls, and the power pins 20 themselves may include three parts: a first portion 201, a second portion 202, and a third portion 203. Wherein the second portion 202 and the third portion 203 are provided on opposite sides of the first portion 201. The first portion 201 is disposed on the first sidewall 12, the second portion 202 protrudes from the bottom wall 11, and the third portion 203 can be connected to the first portion 201 and connected to a side of the first sidewall 12 away from the bottom wall 11. In other words, at least a portion of the third portion 203 is disposed outside the receiving space 13 and is bent and connected to the end side of the first sidewall 12, so that the sectional area of the end side of the power pin 20 can be increased, thereby facilitating the connection between the power pin 20 and other components, and increasing the contact area when two components are connected, thereby reducing the contact resistance and further increasing the transmission speed of the current.

It should be noted that the power pin 20 in this embodiment has three different portions, and the cross-sectional portions of the power pin 20 mentioned in the above embodiments of the present application can also be understood as the cross-sections of the first portion 201 and the second portion 202. The third portion 203 is to increase the cross-sectional area of the end side of the power supply pin 20 to reduce contact resistance and increase the transmission speed of current.

Alternatively, the first portion 201, the second portion 202, and the third portion 203 may be a unitary structure, i.e., the first portion 201, the second portion 202, and the third portion 203 are prepared by a same process, but different portions of the power pin 20 are named differently for ease of understanding. Alternatively, the first portion 201, the second portion 202, and the third portion 203 may be formed in a split structure, that is, the first portion 201, the second portion 202, and the third portion 203 are separately prepared through different processes and then connected together by various methods (e.g., welding, bonding, etc.). Or the first part 201, the second part 202 and the third part 203 are of a split structure and are of an integrated structure, that is, part of the three parts are prepared through the same process, and the rest parts are prepared through different processes and then are connected together through various methods (such as welding, bonding and the like).

Referring to fig. 4 again, in the present embodiment, the third portion 203 protrudes away from the first sidewall 12. This embodiment can form the third portion 203 into a convex structure, which not only can further increase the contact area between the third portion 203 and other components, thereby further increasing the transmission speed of the current. The arc-shaped bulge can be used for guiding, so that the other part socket charging interface 1 is convenient to electrically connect with the power pin 20.

Optionally, the third portion 203 is formed as an arcuate projection in a direction away from the first side wall 12.

Please refer to fig. 12-13 together, fig. 12 is a schematic perspective view of a charging interface according to another embodiment of the present application. FIG. 13 is a schematic cross-sectional view of the charging interface shown in FIG. 12 along the direction C-C. In this embodiment, when the housing 10 includes the bottom wall 11 and the first side wall 12, the bottom wall 11 and the first side wall 12 enclose to form an accommodating space 13, the charging interface 1 further includes at least one data pin 30 installed on the bottom wall 11, a portion of the data pin 30 is disposed in the accommodating space 13, and one end of the data pin 30 penetrates through the bottom wall 11 and is electrically connected to the circuit board.

Charging interface 1 includes a data pin 30 in addition to housing 10 and power pin 20. The data pin 30 is mainly used for allowing a data signal to pass through, so as to realize data transmission between the electronic device 3 and an external terminal, such as short message transmission, picture transmission, video and audio data transmission, application software transmission, and the like. The material of the data pin 30 is usually conductive so as to effectively transmit the electrical signal, and the specific material of the data pin 30 is not limited in this embodiment as long as the electrical signal can be transmitted. And the data pin 30 is spaced apart from the power pin 20 to prevent a short circuit.

With respect to the above-described various arrangements of the power pins 20 and the side walls, the data pins 30 can be mounted on the bottom wall 11, and the data pins 30 are disposed in the accommodating space 13. Although the cross-sectional area of the power pin 20 of the above-mentioned embodiments is larger, it surrounds various sidewalls, so that the internal space of the accommodating space 13 can be effectively utilized, and at least the data pin 30 can still be disposed in the accommodating space 13 as in the related art, and the number, size, structure, and shape of the data pin are not changed, thereby reducing the difficulty in manufacturing. The present embodiment does not limit the above parameters. In addition, the data pins 30 also need to be electrically connected to an external circuit board, so that one end of the data pin 30 mounted on the bottom wall 11 can penetrate through the bottom wall 11 to protrude from the bottom wall 11, thereby facilitating connection with the circuit board and realizing mutual transmission of electrical signals between the data pins 30 and the circuit board.

Optionally, when the housing 10 further includes the second sidewall 14, the data pin 30 may be disposed in the receiving space 15, and the receiving space 13 between the first sidewall 12 and the second sidewall 14 is used for inserting other components.

While various embodiments of the power pin 20 mounted on the first sidewall 12 have been described above, the present application also provides another embodiment of the power pin 20 and the first sidewall 12. Referring to fig. 14 to 18 together, fig. 14 is a schematic perspective view of a charging interface according to another embodiment of the present application. Fig. 15 is a schematic perspective view of the charging interface shown in fig. 14 from another perspective. Fig. 16 is an exploded view of the charging interface shown in fig. 14. Fig. 17 is a schematic cross-sectional view of the charging interface of fig. 14 along the direction D-D. Fig. 18 is a schematic cross-sectional view of the charging interface of fig. 14 taken along the direction E-E. In this embodiment, when the housing 10 includes the bottom wall 11 and the first side wall 12, the bottom wall 11 and the first side wall 12 enclose to form an accommodating space 13, the power pin 20 is installed on the bottom wall 11, a portion of the power pin 20 is disposed in the accommodating space 13, the power pin 20 and the first side wall 12 are spaced apart from each other, the power pin 20 has a contoured surface 23, and the contoured surface 23 has a shape identical to that of the first inner side surface 122 of the first side wall 12.

In the present embodiment, the power pin 20 is mounted on the bottom wall 11, and a portion of the power pin 20 is disposed in the accommodating space 13, but the power pin 20 is spaced apart from the first sidewall 12. In other words, the power pin 20 is only disposed on the bottom wall 11 and one end of the power pin 20 penetrates through the bottom wall 11 and protrudes from the bottom wall 11. The space between the power pin 20 and the first sidewall 12 allows other structural members to be inserted to electrically connect the power pin 20.

In the present embodiment, the power supply pin 20 has the contour surface 23, and the contour surface 23 has the same shape as the receiving space 13. Wherein the contoured surface 23 refers to a part or all of the surface of the peripheral side surface of the power pin 20, and the contoured surface 23 has the same characteristics as the other surface shapes. Specifically, the shape of the contoured surface 23 is the same as the shape of the first inner side surface 122 of the first side wall 12, i.e., the shape of the contoured surface 23 is the same as the shape of the accommodating space 13. In this way, the shape of the receiving space 13 can be fully utilized without changing the size and shape of the receiving space 13, thereby increasing the cross-sectional area of the power pin 20. As shown in fig. 18, the first inner surface 122 is schematically described as being circular, and the housing space 13 is also circular. The contoured surface 23 of the power pin 20 is circular arc shaped, and is the same shape as the first inner side surface 122, further increasing the cross-sectional area of the power pin 20.

Referring to fig. 14-18 again, in this embodiment, the plurality of power pins 20 includes at least one first power pin 21 and at least one second power pin 22, and the first power pin 21 and the second power pin 22 have opposite polarities and are disposed at intervals; the first power pin 21 has a first contoured surface 231, the second power pin 22 has a second contoured surface 232, and the first contoured surface 231 and the second contoured surface 232 are disposed opposite to each other.

From the above, the plurality of power pins 20 includes two power pins 20, i.e., a first power pin 21 and a second power pin 22. The two power pins 20 are described above in detail, and the description of the embodiment is omitted here. The first power lead 21 has a first contour surface 231, and the second power lead 22 has a second contour surface 232, in this embodiment, the first contour surface 231 and the second contour surface 232 are disposed oppositely, in other words, the contour surface 23 of each power lead 20 is closer to the first inner side surface 122 of the power lead 20, so as to further increase the cross-sectional area of the power lead 20 by using a limited space.

As shown in fig. 18, the receiving space 13 has a circular shape, the first contour surface 231 and the second contour surface 232 have a circular arc shape, and the first contour surface 231 and the second contour surface 232 are disposed back to back. The first power pin 21 further has a first plane 241, the second power pin 22 further has a second plane 242, the first plane 241 is spaced apart from the second plane 242,

referring to fig. 19 to 20 together, fig. 19 is a schematic perspective view of a charging interface according to another embodiment of the present application. FIG. 20 is a schematic cross-sectional view of the charging interface of FIG. 19 taken along a direction F-F. In this embodiment, the charging interface 1 further includes at least one data pin 30, the data pin 30 is disposed outside the accommodating space 13 and is installed on the first outer side surface 121 of the first side wall 12, and one end of the data pin 30 protrudes from the bottom wall 11 and is used for electrically connecting the circuit board.

In the above embodiment, charging interface 1 also includes data pin 30. However, the data pin 30 of the present embodiment is not disposed in the housing space 13, but is disposed outside the housing space 13. Thereby reserving more space for the power pin 20 and further increasing the cross-sectional area of the power pin 20. Specifically, the data pin 30 is mounted on the first outer side 121 of the first side wall 12, and one end of the data pin 30 extends from the outer periphery of the bottom wall 11 to the outside of the bottom wall 11 so as to protrude from the bottom wall 11, so that the data pin 30 is electrically connected to the circuit board subsequently.

Alternatively, when the charging interface 1 includes a plurality of data pins 30, the plurality of data pins 30 are spaced around the first side surface.

Referring to fig. 19 and 21 together, fig. 21 is an exploded view of the charging interface shown in fig. 19. In this embodiment, the first outer side surface 121 has a groove 123, and the data pin 30 is partially disposed in the groove 123. In the present embodiment, the data pins 30 can be mounted by using the grooves 123, so that the protrusion degree of the data pins 30 can be reduced by using the grooves 123, and the overall size of the charging interface 1 can be reduced. And the receipt pin can be effectively protected by the groove 123, and the data pin 30 is prevented from being knocked off or damaged by collision with other structures.

Referring to fig. 19 again, in the present embodiment, a surface of the data pin 30 on a side away from the accommodating space 13 is flush with the first outer side surface 121. Because the first appearance surface of the first side wall 12 is the appearance surface of the charging interface 1, the surface of the data pin 30 on the side away from the accommodating space 13 is flush with the first outer side surface 121, so that the flatness of the appearance surface of the charging interface 1 is improved.

Referring to fig. 22, fig. 22 is a schematic cross-sectional view of a power adapter according to an embodiment of the present application. The present embodiment provides a power adapter 2, which includes a first housing 40, a pin 50, a first circuit board 60, and a charging interface 1 provided in the above embodiments of the present application, where the pin 50 can protrude from the first housing 40, the charging interface 1 is installed at an end of the first housing 40, the first circuit board 60 is disposed in a first accommodating space 41 in the first housing 40, and the first circuit board 60 is electrically connected to the pin 50 and a power pin 20 of the charging interface 1. The pin 50 is configured to receive a first voltage in a socket and transmit the first voltage to the first circuit board 60, and the first circuit board 60 is configured to convert the first voltage into a second voltage and transmit the second voltage to the electronic device 3 through the power pin 20.

The power adapter 2 provided by the embodiment of the present application can increase the cross-sectional area of the power pin 20 by using the charging interface 1 provided by the above embodiment of the present application, so as to increase the transmission speed of the current, and enable the power adapter 2 to have a quick charging function.
