[0002] Power cords are wires that transmit current, used to transfer electricity from a power source (such as a socket) to various devices. With the rapid development of modern technology, electrical appliances are used more and more widely in daily life and work, and people's needs for power cords are becoming increasingly diversified. In today's increasingly globalized era, cross-border travel, business exchanges, and international tourism have become the norm. A common problem that arises is that the lack of uniformity in power cord standards in different countries has brought many inconveniences to travelers' electronic devices.

[0003] Most existing power cords adopt a single standard design, meaning that a power cord can usually only be compatible with the socket specifications of a specific country or region. While this design is convenient for local use, it may not be usable directly when used abroad due to different power cord standards, causing trouble for charging portable electronic devices such as mobile phones, tablets, and cameras. Therefore, we need to propose a power cord with a multi-purpose plug. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] A power cord with a multi-purpose plug includes several power input terminals 1. Each power input terminal 1 integrates standardized plug modules for European, American, and British standards: the European plug conforms to CEE 7 / 16 and CEE 7 / 7 standards, employing a two-round pin design without grounding or with a side grounding plate; the American plug uses a two-flat pin plus round grounding structure according to NEMA 5-15P standards; and the British plug is equipped with three rectangular pins according to BS1363 standards and has a built-in replaceable fuse. One end of each power input terminal 1 is fixedly connected to a conductor mid-section 2, which serves as the core carrier for power conversion and management. Internally, it integrates multiple functional modules: a voltage adaptive module converts 85-264V AC input to a uniform 24VDC±5% DC bus voltage via a wide-range AC / DC conversion circuit, and then divides the voltage to the target device's required value via multiple DC / DC step-down circuits; a multi-channel isolation circuit uses a planar transformer and optocoupler isolation components to achieve 4000VAC withstand voltage electrical isolation, meeting IEC standards. The 60601-1 Medical Device Safety Standard applies; the intelligent identification chip is built on an STM32F0 series MCU, pre-stores over 200 device protocol libraries, and can automatically identify connected devices and dynamically adjust output parameters, such as performing 1.5A current limiting protection for digital cameras. The middle section of the conductor also includes a multi-layer shielding structure (aluminum foil + braided copper mesh), embedded temperature sensing fiber optics, and a self-resetting fuse, achieving ≥60dB electromagnetic interference attenuation in the 30MHz-1GHz frequency band, and possessing dual protection mechanisms for overheating and short circuits. Several power output terminals 3 are fixedly connected to one side of the middle section 2. The power output terminals 3 include three types of device adapter interfaces: a USB-C PD module that can output 5-20V / 5A dynamic voltage, supporting 140W fast charging protocol for laptops; a USB-A interface integrating a QC 4.0 intelligent identification chip, compatible with mobile devices such as phones and tablets; and a DC 5.5×2.1mm round port module providing a stable 12V / 3A output, matching digital cameras and network devices. Each output terminal is independently equipped with an overcurrent protection chip, and its action threshold error is controlled within ±5% to avoid current crosstalk when multiple devices are charging at the same time. This design, through the protocol conversion and power management architecture of the middle section 2 of the conductor, enables a single power cord to be compatible with the power grid standards of multiple countries such as Europe, America, and the United Kingdom, while providing safe power supply for devices such as computers, mobile phones, and cameras. This multi-purpose plug power cord can meet the charging or power supply needs of multiple devices and is suitable for use in situations such as international business trips and travel.

[0024] Specifically, a storage housing 4 is fixedly connected to the top of the middle section 2 of the conductor. A divider 5 is fixedly connected to the bottom of the inner wall of the storage housing 4. Several sets of storage cavities 6 are reserved between the divider 5 and the inner wall of the storage housing 4. Two sets of winding posts 7 are fixedly connected to the bottom of the inner walls of the storage cavities 6 respectively. Several sets of wire passage grooves 8 are provided on the two side walls of the storage housing 4 respectively. A cover plate 9 is hinged to the top of the storage housing 4. The above design, through the coordinated use of the storage housing 4, divider 5, storage cavities 6, winding posts 7, wire passage grooves 8 and cover plate 9, serves to store multiple power cords individually, avoiding tangling and knotting between power cords, improving ease of use and portability.

[0025] Specifically, a fixing block 10 is fixedly connected to one side of the cover plate 9, and a protrusion 11 is fixedly connected to the bottom of the fixing block 10. A positioning seat 12 is fixedly connected to one side wall of the housing 4. The protrusion 11 is inserted into the interior of the positioning seat 12, and a groove 13 adapted to the protrusion 11 is opened on the top of the positioning seat 12. The protrusion 11 is inserted into the interior of the groove 13. The above design, through the coordinated use of the fixing block 10, the protrusion 11, the positioning seat 12, the groove 13, and the locking component 14, facilitates the quick and easy locking and positioning of the cover plate 9, preventing displacement during use.

[0026] Specifically, a locking assembly 14 for quickly positioning the cover plate 9 is provided on one side wall of the positioning seat 12. One end of the locking assembly 14 is inserted into the interior of the protrusion 11. The locking assembly 14 includes a fixing sleeve 1401, which is fixedly installed on one side wall of the positioning seat 12. A sliding rod 1402 is slidably inserted into the interior of the fixing sleeve 1401. One end of the sliding rod 1402 passes through the positioning seat 12 and is inserted into the interior of the protrusion 11. The other end of the sliding rod 1402 is fixedly connected to a pull block 1403. With the above design, when it is necessary to open the cover plate 9, the pull block 1403 can be pulled first, which can drive the sliding rod 1402 to move until the end of the sliding rod 1402 separates from the protrusion 11. At this time, the cover plate 9 can be directly lifted.

[0027] Specifically, it also includes a return spring 1404. One end of the return spring 1404 is fixedly connected to one side wall of the pull block 1403, and the other end of the return spring 1404 is fixedly connected to one end of the fixed sleeve 1401. The return spring 1404 is movably sleeved on the outer wall of the slide rod 1402. A blind hole 15 adapted to the slide rod 1402 is opened on one side wall of the protrusion 11, and one end of the slide rod 1402 is inserted into the inside of the blind hole 15.

[0028] In the above design, when the cover plate 9 needs to be closed, the pull block 1403 can be pulled first, which will drive the slide rod 1402 to move. At this time, the return spring 1404 is in a stretched state. Then, the protrusion 11 is inserted into the inside of the groove 13. When the blind hole 15 is aligned with the end of the slide rod 1402, the pull block 1403 is released. The return force of the return spring 1404 can then drive the slide rod 1402 to be firmly inserted into the inside of the blind hole 15, thereby achieving the effect of quickly locking and positioning the cover plate 9.

[0029] Working Principle: This utility model uses standardized plug modules for European, American, and British standards, making it compatible with multiple power grid standards in Europe, America, and the UK. It provides safe power to devices such as computers, mobile phones, and cameras. This multi-purpose plug power cord can meet the charging or power supply needs of multiple devices, making it suitable for international business trips and travel. When it is necessary to store various cables, first open the cover plate 9, then pass the corresponding cable through the cable tray 8 and wind the cable around the winding post 7. Then, press down the cover plate 9 while pulling the pull block 1403, which moves the slide rod 1402. At this time, the return spring 1404 is in a stretched state. Then, insert the protrusion 11 into the groove 13. When the blind hole 15 is aligned with the end of the slide rod 1402, release the pull block 1403. The return force of the return spring 1404 will then firmly insert the slide rod 1402 into the blind hole 15, thus achieving a quick locking and positioning effect for the cover plate 9. This allows unused cables to be stored, preventing cable clutter.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
