[0002] With the rapid development of computer and electronic technology, power cables, as key components for electrical connections, are widely used in computer products. However, existing power cable harnesses are bent and bundled near the connectors, which can lead to inconsistent elasticity of the terminals under long-term stress, resulting in uneven current distribution across the terminals. Utility Model Content

The scope of protection of the present invention shall be determined by the appended claims.

[0026] The basic concepts involved in the embodiments of this utility model are briefly introduced below.

[0027] The term "Central Processing Unit (CPU)" is the core of a computer system for computation and control, and is the final execution unit for information processing and program execution.

[0028] The term "SATA interface" is an abbreviation for Serial ATA, also known as Serial ATA. It was defined in November 2000 by the "Serial ATA Working Group."

[0029] The power cable of this embodiment is used to connect the power interface and functional components. Functional components include, but are not limited to, power-consuming devices such as graphics cards, motherboards, central processing units (CPUs), or SATA interfaces; this embodiment does not impose such limitations.

[0030] Understandably, to enable those skilled in the art to better understand power cables, a detailed description is provided using a power cable configured as a graphics card power supply cable, specifically for connection to a graphics card. It should be noted that the graphics card power supply cable is for illustrative purposes only, and this embodiment of the invention does not impose specific limitations. For example, the product type of the power cable can also be set according to actual needs.

[0031] Please refer to the following: Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of the power cable 100 provided in this embodiment of the utility model; Figure 2 yes Figure 1 An exploded view of the power cable 100 from a first-person perspective; Figure 3 yes Figure 1 The image shows an exploded view of the power cable 100 from a second perspective. The power cable 100 includes a cable body 1 and a functional module 2. The cable body 1 includes a connector 11, a power connector 12, and a connecting harness 13. The connector 11 is used to connect to a functional component, and the power connector 12 is used to connect to a power supply interface. The connecting harness 13 connects the connector 11 and the power connector 12. The functional module 2 includes a protective housing 40, a control circuit board 50, a temperature detector 60, and at least one display structure 70. The protective housing 40 has a receiving cavity 401 and a through hole 402 communicating with the receiving cavity 401. The connecting harness 13 is partially housed in the receiving cavity 401 and extends through the through hole 402. The control circuit board 50 is disposed within the receiving cavity 401. The control circuit board 50 and the connecting harness 13 are arranged in the thickness direction Z of the power cable 100 and are electrically connected to the connecting harness 13. The temperature detector 60 is electrically connected to the control circuit board 50 and is used to detect the temperature of the connecting harness 13. All display structures 70 are electrically connected to the control circuit board 50, and at least one display structure 70 displays the current temperature information of the connection harness 13 detected by the temperature detector 60.

[0032] The power cable 100 provided by this utility model has several advantages. First, it incorporates a functional module 2 on the cable body 1. This module includes a protective shell 40, a control circuit board 50, a temperature detector 60, and at least one display structure 70. The temperature detector 60 can detect the temperature of the connecting harness 13 in real time, and the display structure 70 shows the current temperature information. This allows users to monitor the temperature of the power cable 100 in real time and intervene promptly when the temperature of the power cable 100 is abnormal, preventing the power cable 100 from burning out due to temperature runaway and damaging the graphics card, thus improving the safety of both the graphics card and the power cable 100. Second, the functional module 2 is positioned along the circumferential direction of the connecting harness 13, preventing interference between the functional module 2 and the connector 11 and the graphics card, and improving the overall compactness of the power cable 100. Third, the protective shell 40 protects the control circuit board 50, the temperature detector 60, and at least one display structure 70, improving the safety and environmental resistance of the power cable 100, reducing maintenance costs, and extending the service life of the power cable 100.

[0033] It should be noted that, Figure 1 The purpose is merely to schematically describe the arrangement between the cable body 1 and the functional module 2, and is not to specifically limit the connection position, connection relationship and specific structure of each component. Figure 1 The diagram only illustrates the structure of the power cable 100 in this embodiment of the invention and does not constitute a specific limitation on the power cable 100. In other embodiments, the power cable 100 may include components that are more... Figure 1 The components shown may include more or fewer components, or combinations of certain components, or different components. For example, the power cable 100 may also include, but is not limited to, a cable length adjustment structure, a current detection structure, etc.

[0034] In this embodiment, the functional module 2 is disposed at the end of the connecting harness 13 near the connector 11. This avoids the problem of the functional module 2 being located in the middle or near the middle of the connecting harness 13, which would affect the bending and extension movement of the connecting harness 13. Furthermore, the proximity of the functional module 2 to the connector 11 improves the accuracy and representativeness of the temperature detected by the temperature detector 60. Of course, in some embodiments, the functional module 2 is disposed at other locations on the connecting harness 13; this embodiment does not specify a particular location.

[0035] In some embodiments, the connecting harness 13 includes a first ribbon cable 131, which includes multiple first conductors 1310. The functional module 2 also includes a current sharing element 20. The multiple first conductors 1310 of the first ribbon cable 131 are connected in parallel through corresponding current sharing elements 20. The current sharing element 20 is electrically connected to the control circuit board 50. The temperature detector 60 is used to detect the temperature of the current sharing element 20, wherein the temperature of the current sharing element 20 represents the temperature of the connecting harness 13. Thus, on the one hand, the multiple first conductors 1310 of the first ribbon cable 131 are connected in parallel through the current sharing element 20, so that the current sharing element 20 can evenly distribute the current to each first conductor 1310, thereby avoiding the problem of severe heating of the conductors or contact points corresponding to high current pins due to current imbalance and the problem of impedance difference in the power supply line, thereby extending the service life of the power cable 100 and improving the stability and reliability of the working performance of the functional components connected to the power cable 100.

[0036] The control circuit board 50 is electrically connected to the temperature detector 60, all display structures 70, and the current sharing element 20. The temperature detector 60 is used to detect the temperature of the current sharing element 20. The control circuit board 50 is used to control at least one display structure 70 to display the current temperature information of the current sharing element 20 detected by the temperature detector 60. Thus, the temperature detector 60 can detect the temperature of the connecting harness 13 in real time and display the current temperature information through the display structure 70, making it convenient for users to observe the temperature of the power cable 100 in real time and intervene in time when the temperature of the power cable 100 is abnormal, avoiding the problem of the power cable 100 burning out due to temperature runaway and damaging the graphics card, thereby improving the safety of the graphics card and the power cable 100. It should be noted that since the current sharing element 20 is connected in series with multiple core wires 1311 corresponding to multiple first conductors 1310, the temperature of the current sharing element 20 is close to the temperature of the core wires 1311, thus indirectly measuring the temperature of the first cable 131. The design is reasonable and the structure is compact.

[0037] For example, in this embodiment, the current temperature information includes, but is not limited to, at least one of temperature value and temperature level. Temperature level is characterized by, but is not limited to, at least one of light color, light brightness, light flashing pattern, and text description. The display structure 70 is configured as a display screen or an indicator light. For example, in this embodiment, two display structures 70 are configured, one of which is a display screen used to display temperature value, and the other is an indicator light used to display temperature level. The two display structures 70 can work simultaneously or not simultaneously; for example, the two display structures 70 can work alternately on a cycle or be custom-selected. This embodiment of the present invention does not impose specific limitations.

[0038] Of course, in some embodiments, both display structures 70 can be configured as displays or indicator lights. The functional module 2 may also include a display structure 70, which can display temperature values ​​or temperature levels alone; or, it can display both temperature values ​​and temperature levels simultaneously.

[0039] In some embodiments, the display structure 70 can also be used to display logo information. The logo information can be, but is not limited to, at least one of product model, product name, manufacturer, etc.

[0040] Understandably, when the display structure 70 is configured as an indicator light, the indicator light can represent different temperature levels of the current sharing element 20 by emitting light of at least one of different colors, brightness, and flashing patterns, thereby facilitating users to quickly and accurately understand the temperature of the power cable 100. For example, the temperature of the current sharing element 20 is divided into a high temperature range, a medium temperature range, and a low temperature range. Understandably, multiple levels are set according to different temperature ranges, with higher levels indicating higher temperatures. When the indicator light emits red light, it indicates that the temperature of the current sharing element 20 has reached the highest level (i.e., the high temperature range); when the indicator light emits yellow light, it indicates that the temperature of the current sharing element 20 has reached the medium level (i.e., the medium temperature range); and when the indicator light emits green light, it indicates that the temperature of the current sharing element 20 has reached the lowest level (i.e., the low temperature range). It should be noted that the correspondence between temperature levels and at least one of light color, brightness, and flashing patterns can be user-defined or set by the factory default of the power cable 100, and this embodiment of the present invention does not impose specific limitations.

[0041] The display screen can be configured as a touch screen or a non-touch screen. Thus, the display screen is used to display data and facilitate user interaction, thereby improving the user experience and the usability of the display structure 70. The display screen can also represent different temperature levels corresponding to the current sharing element 20 by displaying patterns with at least one of different colors, brightness, and flickering modes, thereby allowing users to quickly and accurately understand the temperature of the power cable 100.

[0042] In some other embodiments, functional module 2 may also include a speaker. Current temperature information can also be fed back to the user via sound or voice. Functional module 2 includes at least one or a combination of a speaker, a display screen, and an indicator light. Thus, the feedback of current temperature information can be provided through at least one or a combination of sound, light, text description, and voice, thereby improving the recognizability of the current temperature information corresponding to the current equalization element 20. Users can more easily identify the temperature status of the current equalization element 20 based on the current temperature information and take appropriate measures, thereby improving the accuracy and efficiency of handling temperature anomalies in the current equalization element 20.

[0043] The protective housing 40 has a receiving cavity 401 and a through hole 402 communicating with the receiving cavity 401. The connecting wire harness 13 is partially housed within the receiving cavity 401, with one end of the connecting wire harness 13, away from the connector 11, extending through the through hole 402. The control circuit board 50 and the temperature detector 60 are located within the receiving cavity 401. The control circuit board 50 and the connecting wire harness 13 are arranged along the thickness direction Z of the power cable 100 and are electrically connected to the first ribbon cable 131 via a current equalizer 20. Thus, the functional module 2 is arranged along the circumferential direction of the connecting wire harness 13, preventing the functional module 2 from interfering with the connection between the connector 11 and the graphics card, and improving the overall compactness of the power cable 100. Specifically, the plane of the control circuit board 50 is aligned with the extension direction of the first conductor 1310, thereby preventing the control circuit board 50, the temperature detector 60 mounted on the control circuit board 50, and at least one display structure 70 from interfering with the plug-in connection between the connector 11 and the graphics card, resulting in a compact structure.

[0044] In some embodiments, the functional module 2 further includes an insulating member 30, which covers the outside of the current sharing member 20 and has a guide hole 302 for the conductor 80 to pass through. The insulating member 30 is disposed near the connector 11 and spaced apart from the connector 11. A protective shell 40 covers the outside of the insulating member 30 and engages with the end of the connector 11 near the power supply plug 12. Thus, by covering the outside of the current sharing member 20 with the insulating member 30, the insulating member 30 can effectively isolate current, prevent leakage and reduce insulation loss, and prevent moisture, corrosion and mechanical damage, thereby improving the safety and environmental resistance of the power cable 100 and extending the service life of the power cable 100.

[0045] A temperature detector 60 and at least one display structure 70 are mounted on a circuit board. A control circuit board 50 is disposed between an insulating component 30 and a protective housing 40. This facilitates the assembly, maintenance, and replacement of the control circuit board 50, the temperature detector 60, and at least one display structure 70.

[0046] For example, in this embodiment, all display structures 70 are located on the side of the control circuit board 50 facing away from the connecting harness 13 and are electrically connected to the control circuit board 50. This facilitates the routing of the display structures 70 of the functional module 2 on the control circuit board 50, optimizing the structural layout. Of course, the display structures 70 can be located on the side of the control circuit board 50 facing away from the connecting harness 13; and / or, the display structures 70 can also be located on the periphery of the control circuit board 50; and / or, the display structures 70 can also be located on the side of the control circuit board 50 facing the connecting harness 13. It should be noted that the number and location of the display structures 70 can be set according to actual conditions, and this embodiment of the invention does not impose specific limitations.

[0047] The protective housing 40 is provided with at least one mounting hole 403 communicating with the receiving cavity 401. All display structures 70 are mounted in the same mounting hole 403; or, all display structures 70 are mounted in different mounting holes 403. Exemplarily, in this embodiment, the protective housing 40 is provided with two mounting holes 403. Both mounting holes 403 are communicating with the receiving cavity 401, and two display structures 70 are mounted in each hole.

[0048] Specifically, the protective housing 40 includes a first housing 41 and a second housing 42. The first housing 41 and the second housing 42 are fixed together and form a receiving cavity 401 and a through hole 402 communicating with the receiving cavity 401. The connecting wire harness 13 passes through the through hole 402. The side of the first housing 41 facing away from the second housing 42 is provided with a mounting hole 403 communicating with the receiving cavity 401, and the display structure 70 is installed at the mounting hole 403. The number of mounting holes 403 can be set according to the number and arrangement of the display structures 70, and this embodiment of the utility model does not make a specific limitation.

[0049] In this embodiment, the protective housing 40 also includes a locking member 43. The first housing 41 and the second housing 42 are detachably connected via the locking member 43, thereby facilitating the assembly, maintenance, and replacement of various parts of the power cable 100. Specifically, the sidewall of the first housing 41 is provided with a plurality of first lugs 411, and the sidewall of the second housing 42 is provided with a plurality of second lugs 421. One of the first lugs 411 and the second lugs 421 is provided with a connecting hole 4211, and the other of the first lugs 411 and the second lugs 421 is provided with a fixing hole 4111 aligned with the connecting hole 4211. The locking member 43 passes through the connecting hole 4211 and is locked within the fixing hole 4111. The provision of the first lugs 411 and the second lugs 421 enhances the reliability and stability of the connection between the locking member 43 and the first housing 41 and the second housing 42, and saves material for the protective housing, reducing production costs.

[0050] In some embodiments, the first housing 41 and the second housing 42 can also be fixedly connected together by a detachable structure such as a magnetic adsorption structure or a snap fastener; or, the first housing 41 and the second housing 42 can also be fixedly connected together non-detachably by an adhesive method, a welding method or an injection molding method. The embodiments of this utility model do not make specific limitations.

[0051] In some embodiments, the protective housing 40 further includes a decorative panel 44. The decorative panel 44 is located on the side of the first housing 41 facing away from the second housing 42 and is sealed to the first housing 41. The decorative panel 44 covers the mounting hole 403. The decorative panel 44 is independently disposed from the display structure 70 and configured as a transparent structure; alternatively, the decorative panel 44 is integrated with the display structure 70 as an integral structure. Thus, the provision of the cover plate can improve the aesthetic appearance of the power cable 100 and prevent external contaminants or moisture from entering the housing through the mounting hole 403 and damaging the functional components.

[0052] For example, in this embodiment, the decorative panel 44 is configured as a transparent structure, thereby improving the aesthetic appearance of the power cable 100 and making it easier for users to view the information output by the display structure 70. Of course, in some embodiments, the decorative panel 44 can also be configured as a non-transparent structure. The decorative panel 44 can also be integrated with the display structure 70 into an integral structure, that is, the decorative panel 44 is configured as a display screen as a whole, thereby increasing the display area and improving the display effect of the power cable 100, making it easier for users to view.

[0053] In some embodiments, a positioning groove 404 is provided on the side of the first housing 41 facing away from the second housing 42. The decorative panel 44 is disposed within the positioning groove 404. This improves the alignment and assembly efficiency and assembly yield of the decorative panel 44 and the first housing 41.

[0054] In some embodiments, the length of the protective housing 40 in the axial direction X of the first conductor 1310 is less than or equal to 25 cm. This avoids the problem of the protective housing 40 being too long and interfering with the alignment and insertion of the connector 11 and the graphics card, and also improves the aesthetics and structural compactness of the power cable 100. Exemplarily, in this embodiment, the protective housing 40 is configured as an insulating structure. Of course, in some embodiments, the protective housing 40 can also be configured as a non-insulating structure. For example, the protective housing 40 can be configured as a metal structure, thereby improving the structural strength and heat dissipation performance of the protective housing 40. The protective housing 40 can also be provided with a heat dissipation structure to exhaust the heat generated by the current sharing element 20 to the outside air, thereby improving the stability and reliability of the power cable 100's operating performance.

[0055] In this embodiment, multiple first conductors 1310 are arranged at equal intervals. Any two adjacent first conductors 1310 are arranged in parallel. This ensures that the heat distribution of the multiple first conductors 1310 is consistent when carrying current, preventing concentrated heat generation in any one first conductor 1310 due to insufficient spacing. Furthermore, the consistent spacing of the parallel first conductors 1310 reduces mutual inductance under high-frequency current, avoiding voltage fluctuations caused by electromagnetic interference. The evenly spaced first conductors 1310 also ensure uniform stress distribution when bent, preventing individual first conductors 1310 from bearing additional mechanical stress due to spacing compression, and improving installation convenience. Of course, in some embodiments, some of the multiple first conductors 1310 may be arranged at non-equal intervals.

[0056] In this embodiment, for example, each first conductor 1310 includes a core wire 1311 and an insulating sheath 1312. The insulating sheath 1312 covers the outside of the core wire 1311. The insulating sheath 1312 of each first conductor 1310 has a notch 1313 at the end near the connector 11 to expose the core wire 1311. A current sharing element 20 is disposed at the notch 1313 and connected to the core wire 1311. Therefore, on the one hand, the notch 1313 exposing the core wire 1311 in the insulating sheath 1312 facilitates the assembly of the current sharing component 20 and the first conductor 1310; on the other hand, the notch 1313 exposing the core wire 1311 at the end of the insulating sheath 1312 near the connector 11 avoids the problem of the current sharing component 20 being located in the middle of the first conductor 1310, thus affecting the bending and extension movement of the first conductor 1310, and avoids the problem of the current sharing component 20 bending and reducing the reliability and stability of the connection with the core wire 1311. Furthermore, the current sharing component 20 can straighten the end of the first conductor 1310 near the connector 11, thereby improving the reliability and stability of the connection between the connector 11 and the functional component.

[0057] The notch 1313 is annular. Specifically, the notch 1313 is arranged in a circle around the circumference of the first conductor 1310, and the current equalizing element 20 is embedded in the notch 1313. This reduces the processing difficulty of the first conductor 1310 and the current equalizing element 20, and improves the assembly efficiency of the current equalizing element 20 and the first conductor 1310. Furthermore, it increases the connection area between the current equalizing element 20 and the core wire 1311, improving connection reliability and stability, and increasing the space utilization of the current equalizing element 20, thus achieving a miniaturized design. Specifically, the length of the notch 1313 in the axial direction X of the first conductor 1310 can be equal to or slightly greater than the length of the current equalizing element 20 in the axial direction X of the first conductor 1310. Of course, in some embodiments, the notch 1313 can also be arc-shaped. For example, the notch 1313 is arranged in a semi-circular shape around the circumference of the first conductor 1310. The arrangement and position of the notch 1313 can be set according to actual conditions, and this embodiment of the present invention does not impose specific limitations.

[0058] Please refer to the following: Figure 2 and Figure 4 , Figure 4 yes Figure 2 An enlarged view of the current sharing element 20 of the power cable 100. The current sharing element 20 includes a plurality of first connecting portions 21 and at least one second connecting portion 22. The second connecting portion 22 connects between two adjacent first connecting portions 21. The first connecting portion 21 is configured as a hollow cylindrical structure and is sleeved at the position of the core wire 1311 corresponding to the notch 1313. The second connecting portion 22 is configured as an arched structure or a planar structure. Thus, on the one hand, the first connecting portions 21 and the second connecting portions 22 are alternately arranged, so that the second connecting portion 22 can limit the spacing between two adjacent first conductors 1310, thereby making the heat distribution of multiple first conductors 1310 consistent when carrying current, preventing a single first conductor 1310 from concentrating heat due to too small a spacing, and the consistent spacing of multiple parallel first conductors 1310 can reduce the mutual inductance effect under high-frequency current, avoid voltage fluctuations caused by electromagnetic interference, and the stress distribution of the equidistantly arranged first conductors 1310 is uniform when bending, avoiding the additional mechanical stress on a single first conductor 1310 due to spacing compression, and improving the ease of installation. On the other hand, the first connecting part 21 is sleeved at the position of the notch 1313 corresponding to the core wire 1311, thereby increasing the connection area between the current equalizing component 20 and the core wire 1311 and improving the connection reliability and stability. Furthermore, when the second connecting part 22 is configured as an arched structure, the second connecting part 22 can press the first connecting part 21 against the core wire 1311 along the axial direction X, thereby improving the stability and reliability of the connection between the core wire 1311 and the current equalizing component 20, and facilitating the alignment and assembly of the current equalizing component 20 and the insulating component 30. When the second connecting part 22 is configured as a planar structure, it simplifies the processing mold of the current equalizing component 20 and reduces the processing difficulty of the current equalizing component 20.

[0059] In this embodiment, the first connecting part 21 and the second connecting part 22 are integrally formed, thereby improving the reliability and stability of the connection between the first connecting part 21 and the second connecting part 22, and achieving uniformity of the overall mechanical properties of the current equalizing component 20. Specifically, the current equalizing component 20 is disposed on the core wire 1311 by crimping. Thus, on the one hand, the crimping process enables the current equalizing component 20 to form a large-area metal contact with the surface of the core wire 1311, effectively reducing contact resistance and reducing current distribution deviation caused by uneven resistance; on the other hand, the crimped current equalizing component 20 and the core wire 1311 form a permanent mechanical connection, which is not easy to loosen under vibration or bending environment, avoiding local overheating caused by poor contact, and the contact point can withstand high axial tensile force; furthermore, the crimping force and mold size are standardized, avoiding individual differences from manual welding or bolt tightening, ensuring the uniformity of current distribution of each core wire 1311, and improving assembly production efficiency.

[0060] Specifically, the current equalizing element 20 can be in the form of a strip before crimping. This strip structure can be configured as a wavy structure to facilitate the alignment and assembly of multiple first conductors 1310 with the current equalizing element 20. After the current equalizing element 20 is crimped onto the core wire 1311 using a crimping tool, it forms a structure where the first connecting portion 21 and the second connecting portion 22 are arranged alternately. Of course, in some embodiments, the first connecting portion 21 and the second connecting portion 22 can also be independently arranged and fixedly connected. The first connecting portion 21 and the second connecting portion 22 can be fixedly connected by welding or crimping. The current equalizing element 20 can also be disposed on the core wire 1311 by welding or other methods; this embodiment of the invention does not impose specific limitations.

[0061] For example, in this embodiment, the second connecting portion 22 is generally trapezoidal in shape. The shape of the second connecting portion 22 can also be, but is not limited to, semi-circular, rectangular, etc. The bending direction of the second connecting portion 22 is the same as the bending direction of the first connecting portion 21. In other words, the second connecting portion 22 is recessed towards the core wire 1311, thereby providing a sufficiently large adhesion surface during the injection molding process of the insulating component 30, enhancing the reliability and stability of the connection between the insulating component 30 and the current equalization component 20. The material of the current equalization component 20 can be, but is not limited to, copper, copper alloy, aluminum, aluminum alloy, etc. In this embodiment, the material of the current equalization component 20 can be copper.

[0062] The insulating component 30 and the current equalizing component 20 are connected to form an integrated structure. Exemplarily, in this embodiment, the insulating component 30 is injection molded onto the outside of the current equalizing component 20. Thus, based on the injection molding process, the insulating component 30 can tightly wrap around the outside of the current equalizing component 20, forming a uniform insulating layer, thereby improving the insulation performance of the power cable 100 and the reliability and stability of the connection between the current equalizing component 20 and the core wire 1311. Furthermore, the insulating component 30 prevents the connecting wire harness 13 of the power cable 100 from bending and bundling near the connector 11, avoiding the problem of inconsistent elasticity of the corresponding terminals 112 of the connector 11 under long-term stress, thus improving the reliability and stability of the connection between each terminal 112 and the functional component, and improving the current uniformity of each terminal 112.

[0063] Of course, in some embodiments, the insulating element 30 and the current equalizing element 20 are independently arranged and fixedly connected. For example, the insulating element 30 may include two insulators that are fastened to each other, and the current equalizing element 20 and a plurality of first guides are clamped between the two insulators.

[0064] The insulating component 30 is provided with a plurality of spaced-apart wire holes 301. Multiple first conductors 1310 are respectively threaded through the plurality of wire holes 301. Therefore, on the one hand, the spaced-apart wire holes 301 can limit the spacing between two adjacent first conductors 1310, thereby ensuring a uniform heat distribution among the multiple first conductors 1310 when carrying current, preventing concentrated heat generation in any single first conductor 1310 due to insufficient spacing. Furthermore, the uniform spacing of the multiple parallel first conductors 1310 can reduce mutual inductance under high-frequency current, avoiding voltage fluctuations caused by electromagnetic interference. Additionally, the uniform stress distribution of the equidistantly arranged first conductors 1310 during bending prevents individual first conductors 1310 from bearing additional mechanical stress due to spacing compression, and improves installation convenience. On the other hand, the plurality of wire holes 301 can regulate the ends of the first conductors 1310 near the connector 11, thereby improving the reliability and stability of the connection between the connector 11 and the functional component.

[0065] The length of the insulating member 30 in the axial direction X of the first conductor 1310 is greater than the length of the current-equalizing member 20 in the axial direction X of the first conductor 1310. This avoids the problem of the core wire 1311 breaking under external force at the edge of the notch 1313, improves the overall structural strength of the power cable 100, improves the insulation performance of the power cable 100, and improves the reliability and stability of the connection between the current-equalizing member 20 and the core wire 1311. Of course, the length of the insulating member 30 in the axial direction X of the first conductor 1310 can also be equal to the length of the current-equalizing member 20 in the axial direction X of the first conductor 1310.

[0066] In some embodiments, at least one first ribbon cable 131 is provided. At least one current sharing element 20 is provided. Multiple first conductors 1310 of at least one first ribbon cable 131 are connected in parallel through corresponding current sharing elements 20. Thus, multiple first conductors 1310 with the same signal transmission function can achieve current uniformity through the current sharing elements 20.

[0067] For example, in this embodiment, the power cable 100 is configured as a graphics card power supply cable. Two first ribbon cables 131 and two current sharing elements 20 are each configured to be mutually insulated. Multiple first conductors 1310 of each first ribbon cable 131 are connected in parallel through the corresponding current sharing element 20. Therefore, the output signals of the multiple first conductors 1310 of the two first ribbon cables 131 do not interfere with each other, improving the accuracy of signal transmission by the power cable 100.

[0068] Specifically, the two first ribbon cables 131 include a first sub-ribbon cable 132 and a second sub-ribbon cable 134. The first sub-ribbon cable 132 and the second sub-ribbon cable 134 are independently arranged. The first sub-ribbon cable 132 is used to transmit a first signal, and the second sub-ribbon cable 134 is used to transmit a second signal. Each of the first sub-ribbon cable 132 and the second sub-ribbon cable 134 includes six first conductors 1310. Of course, in some embodiments, the first sub-ribbon cable 132 and the second sub-ribbon cable 134 may also include three, four, or more than six first conductors 1310, and this embodiment of the present invention does not impose a specific limitation.

[0069] A surface parallel to the extension direction of the first row of wires 131 is defined as the symmetry plane S, and multiple current equalization elements 20 are arranged in a mirror-symmetric manner relative to the symmetry plane S. This facilitates the alignment and assembly of the insulating element 30 and the current equalization element 20, and improves the uniformity of the mechanical properties of the overall structure.

[0070] The number of first ribbon cables 131 can be the same as the number of current equalizers 20, and each first ribbon cable 131 is connected to a corresponding current equalizer 20. In some embodiments, the number of first ribbon cables 131 and the number of current equalizers 20 can also be different. It should be noted that the number of first ribbon cables 131 and the number of current equalizers 20 are for illustrative purposes only and do not constitute a specific limitation. The number of first ribbon cables 131 and the number of current equalizers 20 need to be designed according to actual product requirements. For example, in some embodiments, the first ribbon cables 131 can also be set to one, three, or more than three. This embodiment of the present invention does not make a specific limitation.

[0071] In some embodiments, the functional module 2 further includes a protective housing 40. An insulating member 30 is disposed near and spaced apart from the connector 11. The protective housing 40 covers the outside of the insulating member 30, and the protective housing 40 engages with the end of the connector 11 near the power supply plug 12. The connecting wire harness 13 extends out of the protective housing 40 away from the connector 11. Thus, on the one hand, the protective housing 40 prevents rigid bending of the connecting wire harness 13 at the end near the connector 11, improving the reliability and stability of the connection between the power cable 100 and the functional component; on the other hand, the protective housing 40 resists and absorbs external impact forces, improving the environmental resistance of the power cable 100, extending the service life of the power cable 100, and reducing maintenance costs.

[0072] In this embodiment, the sidewall of the insulating component 30 is provided with a conductive hole 302. The functional module 2 also includes a conductive component 80. One end of the conductive component 80 is electrically connected to the current equalizer 20, and the other end of the conductive component 80 passes through the conductive hole 302 and is electrically connected to the control circuit board 50. Thus, the conductive hole 302 shortens the connection lines between the conductive component 80, the current equalizer 20, and the control circuit board 50, resulting in neat wiring and improving the reliability and stability of the connection between the control circuit board 50 and the current equalizer 20.

[0073] Specifically, two guide holes 302 are provided, and the two guide holes 302 are separated. Two guide members 80 are also provided, and the two guide members 80 pass through the two guide holes 302 respectively. Thus, the two guide members 80 are isolated by the two guide holes 302, thereby preventing the two current sharing members 20 from interfering with the transmission signals of the two first ribbon cables 131. Specifically, one guide hole 302 is located on the side wall of the insulating member 30 facing the control circuit board 50, and the other guide hole 302 is located on the side wall of the insulating member 30 parallel to the thickness direction Z of the power cable 100. This shortens the connection lines between the guide member 80, the current sharing member 20, and the control circuit board 50, resulting in neat wiring and improving the reliability and stability of the connection between the control circuit board 50 and the current sharing member 20.

[0074] It should be noted that the thickness direction Z of the power cable 100 is perpendicular to the extension direction of the connecting harness 13. The extension direction of the connecting harness 13 is the arrangement direction of the connector 11 and the power supply connector 12, and is parallel to the insertion direction of the connector 11. Exemplarily, in this embodiment, the thickness direction Z of the power cable 100 refers to the arrangement direction of the plurality of first ribbon cables 131; in other words, the thickness direction Z is perpendicular to the plane containing the first ribbon cables 131.

[0075] The number of guide holes 302 can be the same as or different from the number of guide members 80. The number and arrangement of guide holes 302 can be set according to actual conditions, and this utility model embodiment does not impose specific limitations. Specifically, when the number of guide holes 302 is the same as the number of guide members 80 and is set to multiple, multiple guide members 80 are arranged one-to-one with multiple guide holes 302, thereby avoiding interference between different multiple current sharing members 20 on the transmission signals of multiple first ribbon cables 131. In some embodiments, the number of guide holes 302 can be less than the number of guide members 80, and multiple guide members 80 can pass through the same guide hole 302, and the guide members 80 are provided with an insulating cladding, thereby avoiding mutual interference between the guide members 80 on the transmission signals of multiple first ribbon cables 131. Of course, in some embodiments, the insulating member 30 may not be provided with guide holes 302. For example, the guide member 80 can also pass through the wire hole 301 and connect to the circuit board.

[0076] In some embodiments, the insulating member 30 is provided with a positioning structure 31, and the control circuit board 50 is provided with a guiding structure 501 that cooperates with the positioning structure 31. This improves the alignment and assembly of the control circuit board 50 and the insulating member 30, thereby increasing the assembly efficiency and yield. Furthermore, it prevents displacement of the control circuit board 50 in the plane parallel to the axial direction X of the first conductor 1310, improving the reliability and stability of the connection between the control circuit board 50 and the current equalization member 20. One of the positioning structure 31 and the guiding structure 501 is configured as a protruding structure, and the other is configured as a groove structure or a positioning hole that cooperates with the protruding structure.

[0077] In some embodiments, the positioning structure 31 is provided with a limiting step 311, and the control circuit board 50 is attached to the limiting step 311. Thus, on the one hand, the limiting step 311 can lift the control circuit board 50, preventing the control circuit board 50 from contacting the current equalizer and causing a short circuit; on the other hand, the limiting step 311 allows a heat dissipation channel to be formed between the control circuit board 50 and the insulating component 30, so that problems caused by the current equalizer can be discharged through the heat dissipation channel, thereby improving the service life and safety of the power cable 100.

[0078] The temperature detector 60 is positioned close to the current equalizer 20. Exemplarily, in this embodiment, the temperature detector 60 is positioned on the side of the control circuit board 50 facing the current equalizer 20 and close to the guide hole 302, thereby improving the accuracy of the temperature detector 60 in detecting the temperature of the current equalizer 20. The limiting step 311 also provides sufficient space for the assembly of the temperature detector 60. Of course, in some embodiments, the temperature detector 60 may also be positioned on the side of the control circuit board 50 facing away from the insulating member 30; this embodiment of the present invention does not impose specific limitations.

[0079] In some embodiments, the first housing 41 is provided with a first limiting groove 406, and the second housing 42 is provided with a second limiting groove 407 opposite to the first limiting groove 406. In the thickness direction Z of the power cable 100, one end of the insulating member 30 is limited within the first limiting groove 406, and the other end of the insulating member 30 is limited within the second limiting groove 407. Thus, when the first housing 41 and the second housing 42 are fixed together, the insulating member 30 is clamped between the first housing 41 and the second housing 42 in the thickness direction Z of the power cable 100. The provision of the first limiting groove 406 and the second limiting groove 407 enables the insulating member 30 to move within a plane parallel to the extension direction of the first ribbon cable 131, thereby improving the precise assembly of the various structures of the power cable 100 and preventing misalignment of the installation positions of the various structures, thus improving the safety and reliability of the power cable 100.

[0080] Please refer to the following: Figure 2 and Figure 5 , Figure 5 yes Figure 1 A side view of a partial structure of the power cable 100. Exemplarily, in this embodiment, the connector 11 includes a connector body 111 and terminals 112 disposed on the connector body 111. A flange seat 113 is provided on the side of the connector body 111 near the insulator 30. A first housing 41 and a second housing 42 form a groove 405 at the end near the connector 11. The groove 405 engages with the flange seat 113 for fixation. Therefore, on the one hand, the connection between the connector 11 and the first housing 41 and the second housing 42 does not require an additional locking structure, resulting in a simple and compact structure and improved assembly efficiency; on the other hand, it can prevent the connecting harness 13 of the power cable 100 from being bent and bundled near the connector 11, avoiding the problem that the connecting harness 13 is prone to inconsistent elasticity of the corresponding terminals 112 of the connector 11 under long-term stress, thus improving the reliability and stability of the connection between each terminal 112 and the functional component, and improving the current uniformity of each terminal 112; furthermore, it avoids the problem of the core wire 1311 breaking under the action of external force at the edge of the notch 1313, thus improving the overall structural strength of the power cable 100, improving the insulation performance of the power cable 100, and improving the reliability and stability of the connection between the current sharing component 20 and the core wire 1311.

[0081] Of course, in some embodiments, the connector 11 can also be locked and fixed to the first housing 41 and the second housing 42 by an additional locking structure. This utility model embodiment does not make specific limitations.

[0082] In some embodiments, the connecting harness 13 further includes a second ribbon cable 135. The second ribbon cable 135 includes a plurality of second conductors 1351. The second ribbon cable 135 is disposed between the insulator 30 and the protective housing 40. Understandably, since the plurality of second conductors 1351 of the second ribbon cable 135 are used to transmit different data signals, there is no need to perform current sharing on the plurality of second conductors 1351 of the second ribbon cable 135. Thus, by disposing the second ribbon cable 135 between the insulator 30 and the protective housing 40, the protective housing 40 can provide anti-bending protection for the end of the second ribbon cable 135 near the connector 11, improving the reliability and stability of the connection between the power cable 100 and the graphics card.

[0083] In some embodiments, the second ribbon cable 135 and at least one first ribbon cable 131 are arranged in the thickness direction Z of the power cable 100. The second housing 42 is also provided with a receiving groove 408 that communicates with the second limiting groove. The depth of the receiving groove 408 is greater than the depth of the second limiting groove, and the second ribbon cable 135 is received in the receiving groove 408. As a result, the sidewall of the receiving groove 408 and the sidewall of the second limiting groove form a stepped surface, and the receiving groove 408 sinks relative to the second limiting groove, thereby simultaneously realizing the alignment and assembly of the insulating member 30 and the second ribbon cable 135, avoiding displacement of the insulating member 30 relative to the protective housing 40, improving assembly efficiency and assembly yield, and avoiding the problem of excessive compression of the second ribbon cable 135 by the insulating member 30 and damage to the second ribbon cable 135 when the first housing 41 and the second housing 42 are fastened together.

[0084] Of course, in some embodiments, the insulating component 30 may also be wrapped around the outside of the second cable 135 by injection molding; or, the insulating component 30 may be provided with a through hole 301 for the second conductor 1351 of the second cable 135 to pass through; or, the second cable 135 may be disposed on the outside of the receiving cavity 401 of the protective housing. This embodiment of the present invention does not make specific limitations.

[0085] The embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
