Description

Technical Field

[0001] This application relates to the field of charging technology, and in particular to a data cable and a power bank. Background Technology

[0002] In response to consumer demand for portable power banks, the industry has seen designs that utilize the power bank's built-in data cable as a lanyard. In these technologies, the power bank's casing has space for a connecting structure that integrates with the data cable. This structure, connected within the casing, allows the data cable to form a lanyard that can be lifted. However, this occupies internal layout space, such as space on the PCB board, increasing the overall thickness or length of the power bank, making it inconvenient for users to carry or hold. Utility Model Content

[0003] Therefore, it is necessary to provide a data cable that reduces its footprint.

[0004] Some embodiments of this application provide a data cable including a cable body and a connector. The cable body has a transmission line and an input end and an output end connected to both ends of the transmission line, the input end and the output end being configured to connect to different devices; the connector is connected to the transmission line, the transmission line being configured to bend, and at least a portion of the output end is detachably connected to the connector when the transmission line is bent, such that the transmission line forms a lanyard structure.

[0005] In the aforementioned data cable, the connector is located on the transmission line, eliminating the need for space for the connector on devices connected to the input end, thus improving the internal layout of the devices. The connector is detachably connected to the output end, facilitating the formation of a lanyard structure and allowing the output end to be extended to connect to another device.

[0006] According to some embodiments of this application, the output terminal includes a base and a terminal. The base is connected to the transmission line, and the terminal protrudes from the base and is electrically connected to the transmission line. The base and the connector are detachably connected.

[0007] In the above embodiments, the base and the connector form a hanging rope structure for the transmission line. When the hanging rope structure is under force, an interaction force is formed between the base and the connector, and the terminal is not under force, which improves the lifespan of the terminal and the data line.

[0008] According to some embodiments of this application, one of the seat body and the connecting seat is provided with a first groove, and the other of the seat body and the connecting seat is provided with a mating part, which can enter the first groove; one of the groove wall of the first groove and the mating part is provided with a male buckle, and the other is provided with a female buckle, and the male buckle and the female buckle engage or disengage to connect or disengage the seat body and the connecting seat.

[0009] In the above embodiment, the male and female buckles are engaged within the first groove, which isolates them from the environment, reducing the risk of disengagement due to contact or impact. Furthermore, the location of the male and female buckles within the first groove improves the neat appearance of the data cable.

[0010] According to some embodiments of this application, when the connector is provided with a first groove, the terminal protrudes to one side of the mating part and can pass through the first groove.

[0011] In the above embodiments, the first groove can protect the terminal, and the terminal is at least partially accommodated in the first groove, which helps to reduce the space occupied by the output terminal and the connector.

[0012] According to some embodiments of this application, the male buckle is a groove structure formed by the recessed surface portion of one of the groove wall and the mating portion of the first groove, and the female buckle is a protruding structure formed by the protruding surface portion of the groove wall and the mating portion of the first groove.

[0013] In the above embodiments, the male buckle with the groove structure and the female buckle with the protrusion structure are simple in structure, easy to manufacture, and easy to clean.

[0014] According to some embodiments of this application, along the axial direction of the transmission line, at least a portion of the groove wall of the first groove is located near one end of the transmission line to stop the mating portion.

[0015] In the above embodiments, when the hanging rope structure formed by the transmission line is hung up, the surface of the peripheral wall of the mating part close to the transmission line (that is, located above the mating part) fits against the inner peripheral wall of the first groove. The mating part bears the weight of the equipment (power supply equipment) connected to the transmission line, thereby reducing the impact of the equipment weight on the connection between the male and female buckles, and thus improving the connection stability between the male and female buckles.

[0016] According to some embodiments of this application, the peripheral wall of the mating part is provided with a first positioning surface, and the inner peripheral wall of the first groove is provided with a second positioning surface. The first positioning surface and the second positioning surface are similar in shape and have contact or a distance less than a set value.

[0017] In the above embodiment, the first positioning surface and the second positioning surface are planes, and the first positioning surface and the second positioning surface fit together to provide guidance for the mating part to enter the first groove. The first positioning surface and the second positioning surface stop each other. When the distance between the first positioning surface and the second positioning surface is less than a set value, the mating part can rotate a small angle circumferentially in the first groove, and can be corrected by contact between the first positioning surface and the second positioning surface, which facilitates the engagement of the male and female buckles.

[0018] According to some embodiments of this application, the connector is provided with a second groove, and the terminal is accommodated in the second groove.

[0019] In the above embodiments, the first groove accommodates the terminal, reducing the risk of damage to the terminal due to impacts, etc., and also helps to keep the terminal clean.

[0020] According to some embodiments of this application, the base body is provided with a third positioning surface, and the connecting seat is provided with a fourth positioning surface. The third positioning surface and the fourth positioning surface are configured to fit together when the base body and the connecting seat are connected, and are arranged along the direction in which the terminal enters the second groove.

[0021] In the above embodiment, the third positioning surface and the fourth positioning surface stop each other to position the terminal in the second groove, thereby reducing the risk of the terminal end being damaged due to excessive insertion into the second groove.

[0022] According to some embodiments of this application, the second groove passes through the connecting seat, one of the connecting seat and the seat body is provided with a male buckle, and the other is provided with a female buckle. The male buckle and the female buckle are engaged to connect the connecting seat to the seat body. The data cable also includes a pressing member, which is connected to the connecting seat and located on one side of the second groove to align with a terminal entering from the other side of the second groove. The pressing member is configured to deform under a set force to press against the terminal located in the second groove, thereby releasing the male buckle and the female buckle from engagement.

[0023] In the above embodiment, after the pressing member is deformed by force, it will press against the end of the terminal in the second groove. The terminal is forced to move the male buckle relative to the female buckle, so that the male buckle and the female buckle are unfastened. The pressing member is pressed to facilitate the user to unfasten the male buckle and the female buckle.

[0024] According to some embodiments of this application, the terminal extends to one side of the base along the normal direction of the transmission line extension path.

[0025] In the above embodiments, the extension direction of the terminal is approximately perpendicular to the extension path direction of the transmission line. Compared to when the extension direction of the terminal is the same as the extension path direction of the transmission line, when the terminal is connected to the connector along with the base, the area near the connection between the transmission line and the base does not need to be bent, which helps to reduce the loss of the transmission line.

[0026] Some embodiments of this application also provide a portable power bank, which includes a power supply device and a data cable. The data cable includes a cable body and a connector. The cable body has a transmission line and an input end and an output end connected to both ends of the transmission line. The input end is connected to the power supply device. The connector is connected to the transmission line, which is configured to bend. At least a portion of the output end is detachably connected to the connector when the transmission line is bent, such that the transmission line forms a lanyard structure.

[0027] In the aforementioned power bank, the connector is located on the transmission line, eliminating the need for space for the connector on devices connected to the input end, thus improving the internal layout space of the power supply equipment. The connector is detachably connected to the output end, facilitating the formation of a lanyard structure and allowing the output end to be extended for connection to another device.

Detailed Implementation

[0035] The implementation of this application will now be described with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0037] Some embodiments of this application propose a data cable including a cable body and a connector. The cable body has a transmission line and an input end and an output end connected to both ends of the transmission line, the input end and the output end being configured to connect to different devices; the connector is connected to the transmission line, the transmission line being configured to bend, and at least a portion of the output end is detachably connected to the connector when the transmission line is bent, such that the transmission line forms a lanyard structure.

[0038] In the aforementioned data cable, the connector is located on the transmission line, eliminating the need for space for the connector on devices connected to the input end, thus improving the internal layout of the devices. The connector is detachably connected to the output end, facilitating the formation of a lanyard structure and allowing the output end to be extended to connect to another device.

[0039] The following section, in conjunction with the accompanying drawings, provides a detailed description of some embodiments of this application. Unless otherwise specified, the following embodiments and features described herein can be combined with each other.

[0040] Please see Figure 1 and Figure 2 One embodiment of this application provides a data cable 400. The data cable 400 can automatically form a lanyard structure. When the data cable 400 is connected to a device, the user can easily carry and handle the device using the lanyard structure formed by the data cable 400. One end of the data cable 400 can be fixed to a device, or the data cable 400 can be used independently. For example, both ends of the data cable 400 can be detachably connected between a computer and a mobile phone to charge the mobile phone or to complete information transmission between the mobile phone and the computer.

[0041] The data cable 400 includes a cable body 100 and a connector 200. The cable body 100 includes a transmission line 10 and an input terminal 20 and an output terminal 30 connected to both ends of the transmission line 10. The input terminal 20 and the output terminal 30 are configured to connect to different devices. The input terminal 20 can be a wire harness within the transmission line 10, which is directly connected to the internal battery of the device and fixed to the device; alternatively, the input terminal 20 can also be a USB-A interface, which is plugged into a computer via the USB-A interface and detachably connected to devices such as power banks and computers. The output terminal 30 can be a USB-C interface, which is connected to devices such as mobile phones, tablets, and learning machines via the USB-C interface. It is understood that in other embodiments, the input terminal 20 can also be a USB-C interface.

[0042] This application also protects a portable power bank 600. The portable power bank 600 includes a power supply device 500 and a data cable 400. The power supply device 500 is typically a device with a battery structure, such as a power bank.

[0043] The connector 200 is connected to the transmission line 10. The transmission line 10 is configured to bend, and at least a portion of the output end 30 can be detachably connected to the connector 200 when the transmission line 10 is bent. When the output end 30 is connected to the connector 200, the transmission line 10 forms a lanyard structure, such as... Figure 2 As shown. When the output terminal 30 is disconnected from the connector 200, the transmission line 10 can be extended to facilitate connection of the output terminal 30 to another device.

[0044] The connector 200 is located on the transmission line 10. Devices connected to the input terminal 20 do not need to reserve space for the connector 200, thus improving the internal layout space of the device. The connector 200 is detachably connected to the output terminal 30, which facilitates the formation of a lanyard structure and allows the output terminal 30 to be extended to connect to another device.

[0045] In one embodiment, please refer to Figure 2 and Figure 3 The output terminal 30 includes a base 31 and a terminal 33. The base 31 is connected to the transmission line 10. The terminal 33 protrudes from the base 31 and is electrically connected to the transmission line 10. The base 31 is detachably connected to the connector 200. The base 31 and the connector 200 form a lanyard structure for the transmission line 10. When the lanyard structure is under stress, an interaction force is generated between the base 31 and the connector 200, and the terminal 33 is not under stress, thus improving the lifespan of the terminal 33 and the data line 400.

[0046] Please see Figure 3 and Figure 4 In one embodiment, the connecting seat 200 and the seat body 31 are detachably connected by a fastening structure. The connecting seat 200 has a first groove 201, and the seat body 31 has a mating part 311. The mating part 311 can enter the first groove 201. The groove wall of the first groove 201 has a female buckle 202, and the mating part 311 has a male buckle 312. The female buckle 202 and the male buckle 312 fasten together, connecting the seat body 31 to the connecting seat 200; the female buckle 202 and the male buckle 312 are released by force, disengaging the seat body 31 from the connecting seat 200. The male buckle 312 and the female buckle 202 are fastened within the first groove 201, which isolates the male buckle 312 and the female buckle 202 from the external environment, reducing the risk of the male buckle 312 and the female buckle 202 being exposed to the environment and disengaging due to contact or impact. In addition, the male buckle 312 and the female buckle 202 are located in the first groove 201, which improves the neat appearance of the data cable 400.

[0047] It is understood that in other embodiments, the seat 31 and the connecting seat 200 may also be magnetically connected, or the male buckle 312 and the female buckle 202 may be fastened together on the outside of the connecting seat 200 and the seat 31.

[0048] In one embodiment, such as Figure 4As shown, the male buckle 312 is a groove structure formed by the recess of the surface portion of the mating part 311, and the female buckle 202 is a protrusion structure formed by the protrusion of the surface portion of the groove wall of the first groove 201. The female buckle 202 can be elastically deformed, and when the mating part 311 enters the first groove 201, it drives the female buckle 202 to be engaged in the male buckle 312.

[0049] In one embodiment, the female buckle 202 is a long, arc-shaped protrusion, and the first groove 201 is a groove structure adapted to the shape of the female buckle 202, but is not limited thereto. For example, in another embodiment, the female buckle 202 is a cylindrical protrusion, and the second groove 204 is a cylindrical groove. In yet another embodiment, the female buckle 202 is a plurality of spaced dome-shaped protrusions, and the second groove 204 is a corresponding spherical groove. The male buckle 312 with a groove structure and the female buckle 202 with a protrusion structure are simple in structure, easy to manufacture, and easy to clean.

[0050] It is understood that in other embodiments, the female buckle 202 may also be an elastic structure (not shown) that can extend and retract within the connecting seat 200, and the male buckle 312 may be a hole structure. The female buckle 202 may extend elastically into the male buckle 312 of the hole structure, or retract elastically from the male buckle 312 and continue to move along the outer wall of the mating part 311 until the mating part 311 exits the first groove 201 and the female buckle 202 returns to its extended natural state.

[0051] In one embodiment, the outer peripheral wall of the mating part 311 is configured to conform to the inner peripheral wall of the first groove 201, for example, as... Figure 3 As shown, the first groove 201 is generally an oblong groove, and the outer peripheral wall of the mating part 311 is modeled after the inner peripheral wall of the oblong groove. The outer peripheral wall of the first groove 201 can guide the mating part 311 into the first groove 201. It can be understood that in other embodiments, the mating part 311 may also be a rectangular block structure. This application does not limit the shape of the mating part 311 and the first groove 201.

[0052] In one embodiment, at least a portion of the groove wall of the first groove 201 near one end of the transmission line 10 stops the mating portion 311, for example, as Figure 5 As shown, when the hanging rope structure formed by the transmission line 10 is hung up, the surface of the outer peripheral wall of the mating part 311 close to the transmission line 10 (that is, above the mating part 311) fits against the inner peripheral wall of the first groove 201. The mating part 311 bears the weight of the equipment (power supply equipment 500) connected to the transmission line 10, thereby reducing the impact of the equipment weight on the connection between the male buckle 312 and the female buckle 202, and thus improving the connection stability between the male buckle 312 and the female buckle 202.

[0053] Combination Figure 4 and Figure 5In one embodiment, the direction of the fastening connection force between the male buckle 312 and the female buckle 202, and the external force (such as the weight of the device, the overall weight of the data cable 400, etc.) borne by the lanyard structure formed with the transmission line 10, is approximately perpendicular. The terminal 33 extends to one side of the base 31 along the normal direction of the extension path of the transmission line 10. For example, when the transmission line 10 is approximately circular, the normal of the extension path of the transmission line 10 is radial; when the transmission line 10 is a flat square line, the normal of the extension path of the transmission line 10 is parallel to the flat square plane of the transmission line 10.

[0054] It is understood that in other embodiments, the mating part 311 may also be disposed on the connecting seat 200, and the first groove 201 may be disposed on the seat body 31; the male buckle 312 may be disposed on the groove wall of the first groove 201, and the female buckle 202 may be disposed on the mating part 311. For example, as Figure 6 As shown, in another embodiment, in the data cable 400a, the base 31a is provided with a first groove 301, the mating part 211 is formed on the outer wall of the connecting base 200a, the female buckle 210 is formed on the mating part 211, and the male buckle 302 is formed in the first groove 201.

[0055] The extension direction of terminal 33 is approximately perpendicular to the extension path direction of transmission line 10. Compared to when the extension direction of terminal 33 is the same as the extension path direction of transmission line 10, when terminal 33 is connected to connector 200 along with connector 31, the area near the connection between transmission line 10 and connector 31 does not need to be bent, which helps to reduce the loss of transmission line 10.

[0056] Please refer to the following: Figure 3 and Figure 4 If the extension direction of terminal 33 is the same as the extension path direction of transmission line 10, and the fastening force of male buckle 312 and female buckle 202 is parallel to the external force (such as the weight of the equipment) that the transmission line 10 experiences when forming a hanging rope structure, the fastening force of male buckle 312 and female buckle 202 needs to overcome this external force. This places high demands on male buckle 312 and female buckle 202, which is not conducive to the stability of the hanging rope structure formed by transmission line 10. In one embodiment of this application, terminal 33 extends to one side of mating part 311. The mutual resistance between male buckle 312 and female buckle 202 when they fasten together forms a fastening force. This fastening force prevents mating part 311 from disengaging from the first groove 201 along the extension direction of terminal 33. The fastening force of male buckle 312 and female buckle 202 is approximately perpendicular to the force between the inner peripheral wall of the first groove 201 and the outer peripheral wall of the mating part 311. The outer peripheral wall of the mating part 311 fits against the inner peripheral wall of the first groove 201 to bear the weight of the equipment, thereby reducing the risk of the male buckle 312 and the female buckle 202 disengaging, improving the stability of the connection between the male buckle 312 and the female buckle 202, and thus improving the reliability of the data cable 400 forming a lanyard structure.

[0057] In one embodiment, the peripheral wall of the mating part 311 is provided with a first positioning surface 313. The inner peripheral wall of the first groove 201 is provided with a second positioning surface 203. The first positioning surface 313 and the second positioning surface 203 are shaped and in contact or with a distance less than a set value, so that the seat 31 and the connecting seat 200 are positioned circumferentially. The first positioning surface 313 and the second positioning surface 203 are planar, and the first positioning surface 313 and the second positioning surface 203 fit together, providing a guiding function for the mating part 311 to enter the first groove 201. The first positioning surface 313 and the second positioning surface 203 stop each other. When the distance between the first positioning surface 313 and the second positioning surface 203 is less than the set value, the mating part 311 can rotate a small angle circumferentially in the first groove 201, which can be corrected by the contact of the first positioning surface 313 and the second positioning surface 203, so that the male buckle 312 and the female buckle 202 can be fastened.

[0058] In one embodiment, the terminal 33 protruding to one side of the mating portion 311 can pass through the first groove 201, which protects the terminal 33. The terminal 33 is at least partially accommodated in the first groove 201, which helps to reduce the space occupied by the output terminal 30 and the connector 200. It is understood that in other embodiments, the terminal 33 and the mating portion 311 may also be arranged at intervals and located on the same side of the base 31, and the terminal 33 does not pass through the first groove 201.

[0059] In one embodiment, the connector 200 further includes a second groove 204. The terminal 33 is accommodated within the second groove 204. The first groove 201 and the second groove 204 are in communication. It is understood that when the terminal 33 and the mating part 311 are spaced apart, the second groove 204 and the first groove 201 may not be in communication.

[0060] The first groove 201 accommodates the terminal 33, reducing the risk of damage to the terminal 33 due to impacts, and also helps to keep the terminal 33 clean.

[0061] It is understood that in other embodiments, when the base 31 is connected to the connector 200, the terminal 33 may also be located outside the base 31 and the connector 200.

[0062] In one embodiment, the base 31 is provided with a third positioning surface 315. The connecting seat 200 is provided with a fourth positioning surface 205. The third positioning surface 315 and the fourth positioning surface 205 are configured to fit together when the base 31 and the connecting seat 200 are connected, and are arranged along the direction in which the terminal 33 enters the second groove 204. The third positioning surface 315 and the fourth positioning surface 205 stop each other to position the terminal 33 in the second groove 204, thereby reducing the risk of damage to the end of the terminal 33 due to excessive entry into the second groove 204.

[0063] In one embodiment, such as Figure 3 and 4As shown, the data cable 400 also includes a pressing member 300. The pressing member 300 is connected to the connector 200 and is located on one side of the second groove 204 to align with the terminal 33 entering from the other side of the second groove 204. The pressing member 300 is configured to deform under a set force to press against the terminal 33 located in the second groove 204, thereby disengaging the male snap 312 and the female snap 202. The pressing member 300 can be made of a soft material, such as rubber or a thin metal spring. After the pressing member 300 is deformed under force, it presses against the end of the terminal 33 in the second groove 204. The terminal 33, under force, moves the male snap 312 relative to the female snap 202, thereby disengaging the male snap 312 and the female snap 202. The pressure on the pressing member 300 facilitates the user in disengaging the male snap 312 and the female snap 202.

[0064] The pressing member 300 closes one end of the second groove 204, so that when the connecting seat 200 is connected to the seat body 31, the terminal 33 is located in the closed space.

[0065] It is understood that in other embodiments, the pressing member 300 may be omitted, and the second groove 204 does not penetrate the connecting seat 200, so that the terminal 33 is located in a closed space.

[0066] In the aforementioned data cable 400 and power bank 600, the connector 200 is located on the transmission line 10. Devices connected to the input terminal 20 do not need to reserve space for the connector 200, thus improving the internal layout space of the devices. The connector 200 is detachably connected to the output terminal 30, which facilitates the formation of a lanyard structure and allows the output terminal 30 to be extended to connect to another device.

[0067] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and substance of the technical solutions of this application.
