[0001] This application relates to cables, and more particularly to power cables. [Background technology]

[0002] With the rapid development of computer electronics, power cables, a key component of electrical connections, are widely used in computer products. However, the elasticity of the wires in existing power cable connection harnesses is prone to become uneven under long-term stress, which causes uneven current flow through the wire conductors, shortening the service life of the power cable and adversely affecting the performance of the functional elements connected to the power cable. Summary of the Invention [Problem to be solved by the invention]

DETAILED DESCRIPTION OF THE INVENTION

[0007] The power cable provided herein is used to connect a power interface to a functional element. The functional element may include, but is not limited to, a power-consuming device such as a graphics card, a motherboard, a central processing unit, or a Serial Advanced Technology Attachment interface (SATA interface), and the present application is not limited thereto. The power cable may be configured as, but is not limited to, a graphics card power line, a motherboard power line, a central processing unit power line, or a SATA interface power line. The present application uses a graphics card power line as an example for the purpose of explanation only.

[0008] Please also refer to Figures 1A to 2. The power cable 100 includes a cable main body 1 and a functional module 2. The cable main body 1 includes a wiring plug 11, a power plug 12, and a connection harness 13. The wiring plug 11 is used to connect to the functional element A1, and the power plug 12 is used to connect to the power interface A2. The connection harness 13 is connected between the wiring plug 11 and the power plug 12 and includes a first wire 131. The first wire 131 includes a plurality of first conductors 1310. The functional module 2 includes a current equalizing element 20 and an insulating element 30. The plurality of first conductors 1310 of the first wire 131 are connected in parallel via the current equalizing element 20. The insulating element 30 covers the outside of the current equalizing element 20.

[0009] In the power cable 100 provided by the present embodiment, the functional module 2 includes a current equalization element 20 and an insulating element 30. The multiple first conductors 1310 of the first wire 131 are connected in parallel via the current equalization element 20, which can distribute current evenly to each of the first conductors 1310, avoiding problems such as severe heating of the conductors and connection contacts corresponding to high-current pins and impedance differences in the power line caused by current inequality, prolonging the service life of the power cable 100, and improving the stability and reliability of the operational performance of the functional components connected to the power cable 100. In addition, the insulating element 30 covers the outside of the current equalization element 20, effectively blocking current, preventing leakage, reducing insulation loss, and protecting against moisture, corrosion, and mechanical damage, thereby improving the safety and environmental resistance of the power cable 100 and prolonging the service life of the power cable 100.

[0010] In one embodiment, each first conducting wire 1310 includes a core wire 1311. The current equalizing element 20 is connected to the core wire 1311. The functional module 2 is disposed at one end E1 of the connection harness 13 near the wiring plug 11, and the functional module 2 is disposed at or near the center of the connection harness 13, thereby avoiding the problem of the functional module 2 affecting the bending and extension movement of the connection harness 13. In addition, the functional module 2 is disposed near the wiring plug 11, which alleviates the problem of the current equalizing element 20 being bent under the action of a bending force and reducing the connection reliability with the core wire 1311, and improves the effect of the current equalizing element 20 in uniformly distributing the current in the first wiring 1310.

[0011] In one embodiment, the distance between the end of the current equalization element 20 closest to the wiring plug 11 and the wiring plug 11 may be less than 3 cm, but the functional module 2 may be disposed at other positions in the connection harness 13, and the present application is not limited thereto.

[0012] In one embodiment, the plurality of first conductive wires 1310 are equally spaced apart. Any two adjacent first conductive wires 1310 are parallel to one another. Some of the first conductive wires 1310 in the plurality of first conductive wires 1310 may be non-equally spaced apart.

[0013] In one embodiment, each first conducting wire 1310 further includes an insulating sheath 1312. The insulating sheath 1312 covers the outside of the core wire 1311. The insulating sheath 1312 of each first conducting wire 1310 has a notch 1313 at an end E1 close to the wiring plug 11, which exposes the core wire 1311. The current equalizing element 20 is disposed in the notch 1313 and connected to the core wire 1311. This facilitates assembly of the current equalizing element 20 and the first conducting wires 1310, and avoids problems such as the current equalizing element 20 being disposed near the center of the first conducting wire 1310 and affecting the bending and extension movement of the first conducting wire 1310.

[0014] In one embodiment, the notch 1313 is annular, and the current equalization element 20 is disposed in the notch 1313. The notch 1313 may also be arc-shaped, but the present application is not limited thereto.

[0015] 2 and 3. The current equalization element 20 includes a plurality of first connection portions 21 and at least one second connection portion 22. The second connection portion 22 is connected between two adjacent first connection portions 21. The first connection portions 21 are arranged as hollow tubular structures and engage with positions corresponding to the notches 1313 of the core wire 1311. The second connection portions 22 are arranged as arch-shaped or planar structures. Because the first connecting portions 21 and the second connecting portions 22 are alternately arranged, the second connecting portions 22 can limit the spacing between two adjacent first conducting wires 1310, thereby uniformly distributing heat when current flows through the multiple first conducting wires 1310 and preventing concentrated heat generation due to short spacing between specific first conducting wires 1310. By aligning the spacing between the multiple parallel first conducting wires 1310, mutual inductance effects under high frequency currents can be reduced, preventing voltage fluctuations due to electromagnetic interference. Furthermore, the equally spaced first conducting wires 1310 uniformly distribute stress when bending, preventing additional mechanical stress on a single first conducting wire 1310 due to compression of the spacing, improving installation convenience. The first connecting portions 21 engage at positions corresponding to the notches 1313 of the core wires 1311, enlarging the connection area between the current equalizing element 20 and the core wires 1311 and improving connection reliability and stability. When the second connecting portions 22 are arranged in an arched structure, the second connecting portions 22 can crimp the first connecting portions 21 to the core wires 1311 along the axial direction X, improving the stability and reliability of the connection between the core wires 1311 and the current equalizing elements 20 and facilitating the alignment and assembly of the current equalizing elements 20 and the insulating elements 30. When the second connecting portions 22 are arranged in a planar structure, the machining mold for the current equalizing elements 20 can be simplified, and the machining difficulty of the current equalizing elements 20 can be reduced.

[0016] In one embodiment, the first connecting portion 21 and the second connecting portion 22 are integrally formed, and the current equalizing element 20 is disposed on the core wire 1311 by crimping.

[0017] In one embodiment, the current equalization element 20 has a band-like structure before crimping. The band-like structure may be arranged in a wave-like configuration to facilitate alignment and assembly of the multiple first conducting wires 1310 and the current equalization element 20. After the current equalization element 20 is crimped onto the core wire 1311 using a crimping tool, the current equalization element 20 forms a structure in which the first connecting portions 21 and the second connecting portions 22 are alternately arranged. In other embodiments, the first connecting portions 21 and the second connecting portions 22 are arranged independently of each other and fixedly connected by welding or crimping. The current equalization element 20 can also be arranged on the core wire 1311 by welding or other methods, but the present application is not limited thereto.

[0018] In one embodiment, the material of the current equalizing element 20 may be, but is not limited to, copper, copper alloy, aluminum, aluminum alloy, etc. In other embodiments, the first connecting portion 21 may be arranged in any polygonal shape. In some embodiments, the first connecting portion 21 and the second connecting portion 22 may be arranged in a planar structure. That is, the current equalizing element 20 is a flat metal piece. The second connecting portion 22 may be arranged on the core wire 1311 by welding. In some embodiments, the current equalizing element 20 may be formed by solder. Liquid or solid solder may be directly welded onto the multiple core wires 1311, and the solidified solder may become the current equalizing element 20.

[0019] In one embodiment, the insulating element 30 is connected to the current equalization element 20 to form a unitary structure, and the insulating element 30 is injection molded to coat the outside of the current equalization element 20 .

[0020] In one embodiment, the insulating element 30 and the current equalization element 20 are positioned independently of each other and fixedly connected to each other. For example, the insulating element 30 includes two insulators that are fixedly engaged with each other, and the current equalization element 20 and the plurality of first conductors 1310 are clamped between the two insulators.

[0021] The insulating element 30 has a plurality of through holes 301 arranged at intervals. The plurality of first conductive wires 1310 pass through the plurality of through holes 301, respectively.

[0022] In one embodiment, the length of the insulating element 30 in the axial direction X of the first conductor 1310 is equal to or greater than the length of the current equalization element 20 in the axial direction X of the first conductor 1310 .

[0023] In one embodiment, the number of first wires 131 is at least 1. The number of current equalization elements 20 is at least 1. The multiple first conducting wires 1310 of the at least one first wire 131 are connected in parallel via the corresponding current equalization elements 20. This allows the multiple first conducting wires 1310 having the same signal transmission function to achieve current uniformity via the current equalization elements 20.

[0024] In one embodiment, the power cable 100 is a graphics card power line. There are two first wires 131 and two current equalization elements 20, and the two current equalization elements 20 are insulated from each other. The multiple first conductors 1310 of each first wire 131 are connected in parallel via the corresponding current equalization element 20. This prevents output signals from the multiple first conductors 1310 of the two first wires 131 from interfering with each other, improving the signal transmission accuracy of the power cable 100.

[0025] Specifically, the two first wires 131 include a first subwire 132 and a second subwire 134. The first subwire 132 and the second subwire 134 are disposed independently of each other. The first subwire 132 is used to transmit a first signal, and the second subwire 134 is used to transmit a second signal. The first subwire 132 and the second subwire 134 each include six first conductor wires 1310. Of course, in some embodiments, the first subwire 132 and the second subwire 134 may each include three, four, six, or more first conductor wires 1310, and this is not particularly limited in the embodiment of the present application. In this embodiment, the notch of the first subwire 132 and the notch of the second subwire 134 are aligned in the thickness direction Z of the power cable 100, and the two current equalization elements 20 are aligned in the thickness direction Z. This allows one insulating element 30 to simultaneously cover two current equalization elements 20. Of course, in some embodiments, the notch of the first sub-wire 132 and the notch of the second sub-wire 134 may be offset in the thickness direction Z, and the two current equalization elements 20 may be offset in the thickness direction Z. Two insulating elements 30 may be disposed, each covering two current equalization elements 20.

[0026] In one embodiment, a plane parallel to the extension direction of the first wires 131 is defined as a symmetry plane S, and the current equalization elements 20 are arranged in mirror symmetry with respect to the symmetry plane S. This facilitates the alignment and assembly of the insulating elements 30 and the current equalization elements 20, and can improve the uniformity of the mechanical properties of the entire structure.

[0027] The number of first wires 131 may be the same as or different from the number of current equalization elements 20, and the present application is not limited thereto.

[0028] In one embodiment, the functional module 2 includes a protective housing 40. The insulating element 30 is disposed near the wiring plug 11 and spaced apart from the wiring plug 11. The protective housing 40 covers the outside of the insulating element 30. The protective housing 40 is engaged with one end E2 of the wiring plug 11 that is close to the power plug 12, and the connection harness 13 passes through one end E3 of the protective housing 40 that is remote from the wiring plug 11.

[0029] 1A, 2, and 4, in one embodiment, the functional module 2 includes a control circuit board 50, a temperature measuring device 60, and at least one display structure 70. The control circuit board 50 is conductively connected to the temperature measuring device 60, all of the display structures 70, and the current equalization elements 20. The temperature measuring device 60 is used to measure the temperature of the current equalization elements 20. The control circuit board 50 is used to control the at least one display structure 70 to display the current temperature information of the current equalization elements 20 measured by the temperature measuring device 60. In this way, the temperature measuring device 60 can detect the temperature of the connection harness 13 in real time and display the current temperature information via the display structure 70, allowing the user to monitor the temperature of the power cable 100 in real time. Furthermore, by timely intervention when the temperature of the power cable 100 becomes abnormal, problems such as burning of the power cable 100 or damage to the graphics card due to uncontrollable temperature of the power cable 100 can be avoided. Furthermore, since the current equalization element 20 is connected in series with multiple core wires 1311 corresponding to the multiple first conductors 1310, the temperature of the current equalization element 20 is close to the temperature of the core wires 1311, thereby allowing the temperature of the first wires 131 to be measured indirectly.

[0030] In one embodiment, the current temperature information includes, but is not limited to, a temperature value and / or a temperature level. The temperature level may be characterized by, but is not limited to, a light color, a light brightness, a light flashing mode, and / or a text description. The display structure 70 may be a display screen or a light-emitting element, and the present application is not limited thereto. In one embodiment, the number of display structures 70 is two, one of which is a display screen and is used to display a temperature value. The other of which is a light-emitting element and is used to display a temperature level.

[0031] In one embodiment, when the indication structure 70 is a light-emitting element, the light-emitting element can indicate that the current equalization element 20 corresponds to different temperature levels by emitting light of at least one of different colors, brightnesses, and flashing modes, thereby making it easier for the user to understand the temperature of the power cable 100.

[0032] In one embodiment, the display screen is a touch display screen or a non-touch display screen, although the present application is not limited thereto.

[0033] In one embodiment, the function module 2 includes a speaker, a display screen, and / or a light emitting element, and can provide current temperature information to the user via sound or voice.

[0035] In one embodiment, the temperature measuring device 60 and at least one indicating structure 70 are disposed on the control circuit board 50. The control circuit board 50 is disposed between the insulating element 30 and the protective housing 40.

[0036] In one embodiment, the indicator structure 70 is disposed on one side of the control circuit board 50 opposite the connection harness 13 and is conductively connected to the control circuit board 50 .

[0037] In one embodiment, the protective housing 40 has at least one mounting hole 403 that communicates with the receiving cavity 401. The indicating structures 70 can be mounted in the same mounting hole 403 or different mounting holes 403, and the present application is not limited thereto.

[0038] In one embodiment, the protective housing 40 includes a first shell 41 and a second shell 42. The first shell 41 and the second shell 42 are fixed to each other and surround each other to form a receiving cavity 401 and a through-hole 402 communicating with the receiving cavity 401. The connection harness 13 passes through the through-hole 402. A mounting hole 403 communicating with the receiving cavity 401 is disposed on one side of the first shell 41 opposite the second shell 42. The display structure 70 is mounted in the mounting hole 403. The number of mounting holes 403 can be determined depending on the number and installation method of the display structures 70, and the present application is not limited thereto.

[0039] In one embodiment, the protective housing 40 further includes a locking element 43. The first shell 41 and the second shell 42 are detachably connected via the locking element 43. Specifically, a plurality of first convex lugs 411 are arranged on the side wall of the first shell 41, and a plurality of second convex lugs 421 are arranged on the side wall of the second shell 42.

The locking element 43 is fixed in the fixing hole 4111 via the connecting hole 4211. The arrangement of the first convex lugs 411 and the second convex lugs 421 can improve the reliability and stability of the connection between the locking element 43 and the first and second shells 41 and 42.

[0040] In one embodiment, the first shell 41 and the second shell 42 may further be fixedly connected by a magnetic attraction structure, a snap fastener, adhesive bonding, welding, or injection molding, etc., and the present application is not limited thereto.

[0041] In one embodiment, the protective housing 40 includes a decorative plate 44. The decorative plate 44 is disposed on one side of the first shell 41 opposite the second shell 42 and is hermetically connected to the first shell 41, with the decorative plate 44 covering the mounting hole 403. The decorative plate 44 and the display structure 70 are disposed independently from each other and are disposed as a transparent structure, or the decorative plate 44 and the display structure 70 are integrated into a single structure.

[0042] In one embodiment, the decorative plate 44 is of a transparent or non-transparent construction, although the present application is not limited thereto.

[0043] In one embodiment, a positioning groove 404 is disposed on one side of the first shell 41 opposite to the second shell 42. The decorative plate 44 is disposed in the positioning groove 404.

[0044] In one embodiment, the protective housing 40 is a non-insulating structure, such as a metal structure, which improves the structural strength and heat dissipation performance of the protective housing 40. In another embodiment, a heat dissipation structure is disposed in the protective housing 40 to dissipate heat generated by the current equalization element 20 to the outside air.

[0045] In one embodiment, a conductive hole 302 is disposed on a side wall 303 of the insulating element 30. The functional module 2 further includes a conductive element 80. One end E4 of the conductive element 80 passes through the conductive hole 302 and is conductively connected to the current equalizing element 20, and the other end E5 of the conductive element 80 is conductively connected to the control circuit board 50. Thus, the provision of the conductive hole 302 can shorten the connection lines between the conductive element 80 and the current equalizing element 20 and the control circuit board 50.

[0046] In one embodiment, the number of the conductive holes 302 is two, and the two conductive holes 302 are arranged separately. Two conductive elements 80 are also provided, and the two conductive elements 80 pass through the two conductive holes 302 respectively.

[0047] In one embodiment, the number of conductive holes 302 may be the same as or different from the number of conductive elements 80, and the present application is not limited thereto. In one embodiment, the insulating element 30 may not have conductive holes 302, and for example, the conductive elements 80 may be connected to the circuit board through the through holes 301.

[0048] In one embodiment, a positioning structure 31 is disposed on the insulating element 30. A matching guide structure 501 that aligns with the positioning structure 31 is disposed on the control circuit board 50. A protrusion structure is disposed on either the positioning structure 31 or the matching guide structure 501, and a recess structure or a positioning hole that aligns with the protrusion structure is disposed on either the positioning structure 31 or the matching guide structure 501.

[0049] In one embodiment, a restriction step 311 is disposed on the positioning structure 31. The control circuit board 50 is placed on the restriction step 311. The restriction step 311 raises the control circuit board 50, thereby preventing the control circuit board 50 from contacting the equivalent current plate and causing a short circuit. The provision of the restriction step 311 allows a heat dissipation path to be formed between the control circuit board 50 and the insulating element 30.

[0050] In one embodiment, the temperature measuring device 60 is disposed on one side of the control circuit board 50 facing the current equalization element 20 or on one side of the control circuit board 50 opposite the insulating element 30, but the present application is not limited thereto.

[0051] In one embodiment, a first limiting groove 406 is disposed in the first shell 41. A second limiting groove 407 is disposed in the second shell 42, facing the first limiting groove 406.

[0052] 2 and 5. In one embodiment, the wiring plug 11 includes a plug body 111 and a wiring terminal 112 disposed on the plug body 111. A flange seat 113 is disposed on one side of the plug body 111 near the insulating element 30. Ends of the first shell 41 and the second shell 42 near the wiring plug 11 surround each other to form a slot 405. The slot 405 is fitted and fixed to the flange seat 113.

[0053] In one embodiment, the wiring plug 11 and the first and second shells 41 and 42 may be locked and fixed via an additional locking structure, but the present application is not limited thereto.

[0054] In one embodiment, the connection harness 13 includes a second wire 135. The second wire 135 includes a plurality of second conductors 1351. The second wire 135 is disposed between the insulating element 30 and the protective housing 40.

The second shell 42 is further provided with an accommodating groove 408 that communicates with the second limiting groove 407. The depth of the accommodating groove 408 is deeper than the depth of the second limiting groove 407, and the second wire 135 is accommodated in the accommodating groove 408. As a result, the groove sidewalls of the accommodating groove 408 and the groove sidewalls of the second limiting groove 407 form a stepped surface, and the accommodating groove 408 sinks into the second limiting groove 407, thereby simultaneously achieving the alignment and assembly of the insulating element 30 and the second wire 135.

[0056] In one embodiment, the insulating element 30 may be formed by injection molding to cover the outside of the second wire 135. Alternatively, the insulating element 30 may have a through-hole 301 through which the second conductor 1351 of the second wire 135 passes. Alternatively, the second wire 135 may be disposed outside the accommodating cavity 401 of the protective shell, and this is not particularly limited in the embodiment of the present application. In some embodiments, the functional module 2 may include only the current equalization element 20 and the insulating element 30.

[0057] In summary, the power cable of the present application adds a functional module including a current equalizing element and an insulating element. On the one hand, the multiple first conductors of the first wire are connected in parallel via the current equalizing element, so that the current equalizing element can distribute current evenly to each of the first conductors, thereby avoiding problems such as severe heating of the conductors and connection contacts corresponding to high-current pins and impedance differences in the power line caused by current inequality, prolonging the service life of the power cable and improving the stability and reliability of the operating performance of the functional components connected to the power cable. On the other hand, by covering the current equalizing element with an insulating element, the insulating element can effectively interrupt current, prevent leakage, reduce insulation loss, and protect against moisture, corrosion, and mechanical damage, thereby improving the safety and environmental resistance of the power cable and prolonging the service life of the power cable.
