Description
Technical Field
[0001] This utility model relates to the technical field of data cables, and in particular to a three-in-one data cable. Background Technology
[0002] With the widespread adoption and diversification of electronic devices, data cables, as essential tools for connecting devices for charging and data transfer, are facing increasing demands for functionality and applicability. Currently, most data cables on the market feature a single interface design or support only a limited number of multi-interface outputs, making it difficult to meet users' needs for simultaneously charging or transferring data to multiple different devices. Furthermore, existing multi-interface data cables have limitations in usage scenarios, such as inconvenience in operation at specific angles or in confined spaces, and a lack of intuitive charging status indicators. These issues force users to frequently change data cables or adjust device positions, reducing efficiency and convenience. Simultaneously, in some special scenarios, such as applications using payment devices, the existing data cable design cannot meet the needs for flexible control and status monitoring. Therefore, developing a data cable that simultaneously supports multiple interface outputs, features a flexible angle design, and integrates status indication functions has become a pressing issue in the current technological field. Utility Model Content
[0003] The purpose of this utility model is to provide a three-in-one data cable to overcome the shortcomings of the existing technology.
[0004] To achieve the above objectives, this utility model provides the following technical solution: A three-in-one data cable includes a Type-C connector at the input end, a cable harness, a mid-path switch, and multiple connectors at the output end. The Type-C connector at the input end is electrically connected to the input end of the mid-path switch via the cable harness, for connecting to a power source or data source. The output end of the mid-path switch is connected to a pair of Type-C connectors and a right-angle connector, respectively, wherein the pair of Type-C connectors and the right-angle connector are used to provide charging or data transmission functions for multiple electronic devices. An indicator light is provided on the mid-path switch to display the operating status of the data cable, allowing users to monitor the charging or data transmission process in real time.
[0005] Furthermore, the right-angle connector is designed with a 90-degree bend, which has a fixed bending angle and stable structure, reducing the space occupied and making it suitable for space-constrained applications, thus improving ease of use. Specifically, the internal conductive part of the right-angle connector is made of copper alloy material and wrapped with a polymer insulating layer to ensure stable conductivity and mechanical strength even when bent.
[0006] Furthermore, the intermediate switch has an on / off control function, using a built-in miniature relay to open and close the circuit. This allows for applications in toll collection scenarios or other situations requiring power or data transmission management, enhancing the functionality and applicability of the data cable. The intermediate switch's housing is made of high-temperature resistant and flame-retardant material with a non-slip textured surface for easy user operation. In addition, the intermediate switch's circuitry integrates an overcurrent protection module; when the detected current exceeds a preset threshold, it automatically cuts off the circuit to prevent equipment damage.
[0007] Furthermore, the wire harness is braided from multiple strands of wire, each strand having a diameter between 0.15 mm and 0.2 mm. The outer layer of the wires is coated with polyurethane material, providing excellent flexibility and tensile strength, ensuring normal operation even under frequent bending. The braiding density of the wire harness is 80 to 120 wires per square centimeter, thereby improving tensile strength while maintaining flexibility. In addition, the outer layer of the wire harness is coated with an anti-oxidation coating to extend service life and reduce the impact of external environmental factors on wire performance.
[0008] Specifically, the indicator light is preferably a low-energy LED light with an operating voltage range of 3 to 5 volts. It offers moderate brightness and is easy to observe, clearly displaying the data cable's operating status under different lighting conditions. The indicator light is connected to the main circuit of the intermediate switch via a resistor voltage divider circuit. When current flows through the main circuit, the indicator light illuminates; when the main circuit is disconnected, the indicator light turns off, thus visually reflecting the data cable's operating status.
[0009] The technical solution of this utility model also includes the following specific implementation methods: S1, the Type-C connector at the input end is connected to an external power supply or data source through a built-in pin structure, with 24 pins supporting the PD fast charging protocol and the USB 3.1 data transmission standard; S2, the wires inside the harness are divided into two groups, one group for transmitting power signals and the other group for transmitting data signals, and the two groups of wires are isolated by a shielding layer to avoid signal interference; S3, the output end of the intermediate switch is connected to two Type-C connectors and one right-angle connector, each of which is equipped with an independent current limiting circuit to automatically adjust the output current according to the needs of the connected device; S4, the bent part of the right-angle connector has an embedded metal support frame to enhance structural stability and reduce the risk of breakage due to long-term bending.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The one-to-three design allows multiple devices to connect and charge or transfer data simultaneously, solving the problem of simultaneous use of multiple devices. The right-angle connector design optimizes space utilization and makes it easy to use in confined spaces, improving the product's practicality. The introduction of a mid-circuit switch not only enables circuit on / off control but also provides real-time feedback on the working status through indicator lights, enhancing the user experience. The cable harness adopts a multi-strand braided structure, ensuring the durability and reliability of the data cable under frequent use conditions.
[0011] In summary, the three-in-one data cable of this utility model has a reasonable design and multiple functions. Through specific structural design and technical implementation, it solves a number of problems existing in the prior art. It can be widely used in various scenarios such as home, office and public places, and has high practical value and market prospects. Attached Figure Description

[0014] Combination Figure 1 and Figure 2 As shown, this utility model provides a specific embodiment of a three-in-one data cable. The data cable includes a Type-C connector 1, a cable harness 2, a mid-range switch 4, a right-angle connector 3, and an indicator light 5. These components, through reasonable structural design and functional allocation, meet the needs of charging and data transmission for multiple devices, and offer multiple advantages such as status indication, space optimization, and enhanced security.
[0015] Type-C connector 1 serves as the input terminal of the entire data cable, electrically connecting to the input terminal of intermediate switch 4 via wire harness 2. Type-C connector 1 features a 24-pin design, supporting PD fast charging protocol and USB 3.1 data transfer standard, providing efficient access to external power sources or data sources. In practical applications, users can plug Type-C connector 1 into laptops, chargers, or other devices supporting Type-C interfaces to power or transmit data to devices with multiple output terminals. Wire harness 2 is braided from multiple strands of wire, with each strand having a diameter between 0.15 mm and 0.2 mm, ensuring good flexibility and tensile strength. The internal wires of wire harness 2 are divided into two groups: one for transmitting power signals and the other for transmitting data signals. The two groups are isolated by a shielding layer to prevent signal interference. The outer layer of wire harness 2 is coated with an anti-oxidation coating, further enhancing its durability and allowing it to continue operating normally even under frequent bending.
[0016] The intermediate switch 4, as one of the core components of this utility model, performs the functions of circuit on / off control and status indication. The casing of the intermediate switch 4 is made of high-temperature resistant and flame-retardant material, with an anti-slip texture on the surface for easy user operation. The intermediate switch 4 incorporates a miniature relay, which opens and closes the circuit through the closing and opening of mechanical contacts. This design is suitable not only for multi-device connections in ordinary scenarios but also for managing power or data transmission in paid scenarios. For example, in shared charging stations, the intermediate switch 4 can remotely control the circuit's on / off state through a backend management system, thereby achieving on-demand power supply. Furthermore, the circuit of the intermediate switch 4 integrates an overcurrent protection module. When the detected current exceeds a preset threshold, the overcurrent protection module automatically cuts off the circuit to prevent damage to the equipment due to excessive current. The indicator light 5 is located on the surface of the intermediate switch 4, preferably a low-energy LED light with an operating voltage range of 3 to 5 volts, moderate brightness, and easy visibility. Indicator light 5 is connected to the main circuit of intermediate switch 4 via a resistor voltage divider circuit. When current flows through the main circuit, indicator light 5 illuminates; when the main circuit is disconnected, indicator light 5 turns off, thus visually reflecting the working status of the data cable. In practical use, users can determine whether the data cable is in working condition by observing the status of indicator light 5, thereby improving operational convenience.
[0017] The output terminals of the intermediate switch 4 are connected to a pair of Type-C connectors and a right-angle connector 3. Each Type-C connector is equipped with an independent current-limiting circuit, which can automatically adjust the output current according to the needs of the connected device. For example, when one Type-C connector is connected to a mobile phone, the current-limiting circuit will automatically adjust the output current to 5V / 2A according to the phone's charging protocol; when the other Type-C connector is connected to a tablet, the current-limiting circuit will adjust the output current to 9V / 2A. This design allows different devices to receive matching charging power simultaneously, avoiding device damage or low charging efficiency caused by current mismatch. The right-angle connector 3 is designed with a 90-degree bend, with a fixed bending angle and stable structure, which reduces the space occupied and is suitable for space-constrained usage scenarios. For example, in a small desktop environment, the right-angle connector 3 can effectively avoid the interference of traditional straight connectors with the normal use of other devices due to excessive space occupation. The internal conductive part of the right-angle connector 3 is made of copper alloy material and wrapped with a polymer insulating layer to ensure stable conductivity and mechanical strength even when bent. To further enhance the durability of the right-angle connector 3, its bent portion is embedded with a metal support frame, which can significantly reduce the risk of breakage due to long-term bending.
[0018] In practical applications, this 3-in-1 data cable can be widely used in various scenarios such as homes, offices, and public places. For example, in a home environment, users can plug the Type-C connector 1 into a charger on a wall socket and then charge multiple devices simultaneously using the mid-cycle switch 4. At this time, the two Type-C connectors can connect to a mobile phone and a tablet respectively, while the right-angle connector 3 can connect to a game controller or other devices requiring a special angle for insertion. In an office environment, this data cable can connect to a laptop, providing data transmission functionality for multiple peripheral devices, while the indicator light 5 provides real-time monitoring of the data transmission status. In public places such as airport waiting areas or cafes, users can plug the Type-C connector 1 into a shared charging station and charge multiple portable electronic devices using the mid-cycle switch 4, which is both convenient and efficient.
[0019] The technical solution of this utility model also includes a detailed description of its operating principle and process. S1. When the Type-C connector 1 is plugged into an external power source or data source, the power signal and data signal are transmitted to the intermediate switch 4 via the wiring harness 2. S2. The miniature relay inside the intermediate switch 4 is in the off state by default. The user needs to manually press the button on the intermediate switch 4 to close the circuit. At this time, the indicator light 5 illuminates, indicating that the circuit is connected. S3. After the circuit is connected, the power signal and data signal are transmitted to the two Type-C connectors and the right-angle connector 3 respectively through the output terminal of the intermediate switch 4. S4. The current-limiting circuit of each connector automatically adjusts the output current according to the needs of the connected device, ensuring that the device can safely and efficiently charge or transmit data. S5. When the user needs to disconnect the circuit, pressing the button on the intermediate switch 4 again disconnects the miniature relay, the indicator light 5 goes out, and the circuit stops working. Throughout the process, the overcurrent protection module of the intermediate switch 4 continuously monitors current changes. Once an abnormality is detected, it immediately cuts off the circuit to protect the device.
[0020] In summary, this utility model's three-in-one data cable, through reasonable structural design and technical implementation, solves the problems of limited interface types, restricted applicability, and lack of status indication functions in existing technologies. Its specific implementation fully demonstrates the product's practicality, reliability, and innovation, meeting the needs of simultaneous charging or data transmission for multiple devices, and exhibiting excellent performance in various scenarios.
