The cross-sectional area of the inner wall of the second hollow portion 120 is larger than that of the inner wall of the first hollow portion 110. The cross-sectional area of the second solid portion 121 is larger than that of the first solid portion 111. Plug 10 further includes a housing 13 and an insulator 14. The cross-sectional shape of the plug 10 can be freely set as desired, and preferably, the cross-section of the plug 10 in fig. 1 has a flat structure with circular arc-shaped sides. At least two data interfaces 11 with the same specification and at least two power interfaces 12 with the same specification are arranged in the shell 13, an insulator 14 is arranged in the shell 13 and used for fixing the data interfaces 11 and the power interfaces 12, and the top end of the first hollow part 110 and the top end of the second hollow part 120 are exposed out of the shell. The inner walls of the first and second hollow portions 110 and 120 have any one of a circular, square, triangular, rectangular, and oval cross-section.

In an embodiment of the present invention, referring to fig. 1-2, the at least two data interfaces with the same specification may include a first data interface 113, a second data interface 114, a third data interface 115, and a fourth data interface 116, and the at least two power interfaces 12 with the same specification may include a first power interface 123, a second power interface 124, a third power interface 125, and a fourth power interface 126.

The size of the data interface 11 and the power interface 12 in the embodiment of the present invention can be set according to actual requirements, and is about 1-2 mm. The larger diameter of the power interface 12 means that the cross-section thereof is larger, so that the data interface 11 and the power interface 12 can have a high current capability, preferably a high current capability of 20-30A, wherein in particular the first data interface 11 and the power interface 12 can have a high current capability of 10-15A. For example, as shown in fig. 3, the first data interface 113, the second data interface 114, the third data interface 115, and the fourth data interface 116 may be arranged in a square. Correspondingly, the first power interface 123, the second power interface 124, the third power interface 125, and the fourth power interface 126 are disposed at two sides of the square and are symmetrically arranged.

The polarities of the diagonal data interfaces are the same (for example, the polarities of the diagonal data interfaces may be the same as d + in the USB data signal or the polarities of the diagonal data interfaces may be the same as d-' in the USB data signal), and the polarities of the two adjacent data interfaces are opposite to each other (for example, the polarities of the diagonal data interfaces may be the same as d-, or the polarities of the adjacent data interfaces may be the same as d +), respectively. The two power interfaces located on the inner side have the same polarity (e.g., can be the same as V + or V-in the USB power signal), the two power interfaces located on the outer side also have the same polarity (e.g., can be the same as V-or V + in the USB power signal), and the two power interfaces located on the same side have opposite polarities.

Specifically, referring to fig. 3, the polarity of the first data interface 113 is the same as the polarity of the third data interface 115, and is either positive or negative, while the polarity of the second data interface 114 is the same as the polarity of the fourth data interface 116 and is opposite to the polarities of the first data interface 113 and the third data interface 115. The polarity of the first power interface 123 is the same as the polarity of the fourth power interface 126, which is either positive or negative. The polarity of the second power interface 124 is the same as the polarity of the third power interface 125, and is opposite to the polarities of the first power interface 123 and the fourth power interface 126, so that the plug 10 can be charged and data can be transmitted normally even when it is plugged reversely.

In one embodiment of the present invention, the diameter of the data interface 11 is preferably 0.5mm, and the diameter of the power interface 12 is preferably 1.3 mm. The center distance between two adjacent data interfaces is preferably 1.4mm, the center distance between two inner power interfaces is preferably 5.8mm, and the center distance between two outer power interfaces is preferably 11 mm. The width of the inside of the housing of the plug 10 is preferably 15.2mm and the height is preferably 3.2mm, the height of the inside of the plug 10 is preferably 3.2mm and the height of the outside is preferably 4.84 mm.

The plug 10 of the embodiment of the invention can be used in other electronic devices such as a USB interface, a portable mobile device, a tablet computer, a notebook, a Bluetooth headset, an automobile and the like.

The power interface and the data interface can be made of copper conductive materials, and the insulator can be made of hard high-temperature resistant plastic materials, so that the power interface and the data interface can be suitable for the standards of restriction of Hazardous substance directives (Rohs) and flame retardant grades UL94-V0 in electronic and electrical equipment.

Due to the large size of the power interface, the connector 10 can be adapted to high currents, which in turn makes it possible to increase the charging speed and to be used for different devices.

As shown in fig. 4, in an alternative embodiment of the present invention, the first data interface 213, the second data interface 214, the third data interface 215, and the fourth data interface 216 may also be arranged in a straight line and have the same interval, and correspondingly, the first power interface 223, the second power interface 224, the third power interface 225, and the fourth power interface 226 are disposed at two sides of the straight line and are symmetrically arranged. The plug of this embodiment has an oval flat configuration in cross-section.

In the embodiment shown in fig. 4, the first data interface 213 and the fourth data interface 216 located at the outer side have the same polarity, and are both positive electrodes or both negative electrodes. The second data interface 214 and the third data interface 215 located at the inner side have the same polarity and are opposite to the polarity of the first data interface 213 and the fourth data interface 216. Similarly, the first power interface 223 and the fourth power interface 226 located at the outer sides have the same polarity, and are both positive electrodes or both negative electrodes. The second power interface 224 and the third power interface 225 located at the inner side have the same polarity, and have the opposite polarity to the first power interface 223 and the fourth power interface 226. Therefore, the reverse plug condition does not exist, namely, the data can be normally charged and transmitted when the plug 10 is reversely plugged.

As shown in fig. 5, the data interface is specifically a first data interface and a second data interface, and the power interface is specifically a first power interface and a second power interface. The first data interface 313, the second data interface 314, the first power interface 323, and the second power interface 324 may be arranged in a central symmetry. The polarity of the first data interface 313 is opposite to that of the second data interface 314, and the polarity of the first power interface 323 is opposite to that of the second power interface 324.

Because the polarity distribution of the data interface and the power interface is not symmetrically arranged, the data interface and the power interface cannot be reversely inserted, otherwise, the data interface and the power interface can be burnt. To prevent a reverse plug condition, the plug may further include an anti-reverse plug assembly 33, the anti-reverse plug assembly 33 being used to prevent reverse plug of the plug. The anti-reverse-insertion assembly 33 may be configured as a concave block or a convex block, and is not limited in shape to be used with a corresponding socket.

As shown in fig. 6, the first data interface 413, the second data interface 414, the first power interface 423, and the second power interface 424 may be arranged in a non-central symmetrical manner. The polarity of the first data interface 413 is opposite to that of the second data interface 414, and the polarity of the first power interface 423 is opposite to that of the second power interface 424.

Because the polarity distribution of the data interface and the power interface is not symmetrically arranged, the reverse insertion cannot be performed, otherwise, the performance, the service life and the like of the plug are influenced. To prevent a reverse plug condition, the plug may also include an anti-reverse plug assembly 43 for preventing reverse plug.

The shape of the socket used in cooperation with the plug in the above embodiments is similar to the shape of the plug used in cooperation therewith. Taking fig. 7 as an example, fig. 7 is a schematic structural diagram of a socket according to an embodiment of the invention.

The data connectors include a first data connector 501, a second data connector 502, a third data connector 503, and a fourth data connector 504. The power connectors include a first power connector 511, a second power connector 512, a third power connector 513, and a fourth power connector 514. The cross-sectional area of the inner wall of the data connector is greater than the cross-sectional area of the inner wall of the power connector. The cross-section of the socket 50 is a flat structure with circular arcs on both sides.

The first data connector 501, the second data connector 502, the third data connector 503 and the fourth data connector 504 may be arranged in a square or rectangle, and correspondingly, the first power connector 511, the second power connector 512, the third power connector 513 and the fourth power connector 514 are disposed at two sides of the square or rectangle and are symmetrically arranged. The polarities of the diagonal data connectors are the same (for example, the data connectors can be the same as d + in the USB data signal or the same as d-in the USB data signal), and the polarities of the two adjacent data connectors are opposite (for example, the data connectors can be the same as d-in the USB data signal or the same as d + in the USB data signal). The two power connectors located on the inner side have the same polarity (for example, the two power connectors can be the same as V + or V-in the USB power signal), the two power connectors located on the outer side have the same polarity (for example, the two power connectors can be the same as V-or V + in the USB power signal), and the two power connectors located on the same side have opposite polarities.

Taking fig. 7 as an example, the first data connector 501, the second data connector 502, the third data connector 503 and the fourth data connector 504 are arranged in a square. Correspondingly, the first power connector 511, the second power connector 512, the third power connector 513 and the fourth power connector 514 are disposed at two sides of the square and are symmetrically arranged. The polarity of the first data connector 501 is the same as that of the third data connector 503, and is either positive or negative, and the polarity of the second data connector 502 is the same as that of the fourth data connector 502 and is opposite to that of the first data connector 501 and the third data connector 503. The polarity of the first power connector 511 is the same as that of the fourth power connector 514, and is either positive or negative. The polarity of the second power connector 512 is the same as that of the third power connector 513 and is opposite to that of the first power connector 511 and the fourth power connector 514, so that the normal charging and data transmission can be performed even when the socket 50 is plugged backwards.

In one embodiment of the present invention, the receptacle 50 is sized as shown in fig. 8, with the data connector having a diameter of 0.5mm and the power connector having a diameter of 1.3 mm. The center distance between two adjacent data connectors is 1.4mm, the center distance between two power connectors at the inner side is 5.8mm, and the center distance between two power connectors at the outer side is 11 mm. The width of the inner side of the housing of the socket 50 is 15.3mm, the width of the outer side is 16.1mm, the height of the inner side of the socket 50 is 3.3mm, and the height of the outer side is 4.1 mm. The overall length of the receptacle 50 is 2.5mm and the length of the data and power connectors extending out of the receptacle is 2.5 mm.

The socket 50 of the embodiment of the invention can be used for microUSB interfaces, portable mobile devices, tablet computers, notebooks, Bluetooth headsets, automobiles and other electronic devices.

The power connector and the data connector can be made of copper conductive materials, and the insulator can be made of hard high-temperature-resistant plastic materials, so that the power connector and the data connector are suitable for Rohs standards and UL94-V0 and are suitable for SMT (surface mount technology) processes. Due to the large size of the data and power connectors, the connector 10 can accommodate large currents, thereby allowing for faster charging speeds and different devices. Fig. 9 is a schematic diagram of an example of the socket 50 applied to a mobile device.

In summary, the data connector corresponding to the inner wall shape of the first hollow part is accommodated in the hollow first hollow part of the data interface, the power connector corresponding to the inner wall shape of the second hollow part is accommodated in the hollow second hollow part of the power interface, the cross-sectional area of the inner wall of the second hollow part is larger than that of the inner wall of the first hollow part, and the cross-sectional area of the second solid part is larger than that of the first solid part, so that the plug connector can be applied to large current, and the charging speed can be accelerated compared with a plug with the size of the data interface and the size of the power interface.
