[0006] To achieve the above objectives, the present invention adopts the following technical solution:

They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] like Figure 2-5 As shown, this utility model discloses a power connection cable. In a first embodiment, the power connection cable includes a first connector 10, a second connector 20, and a wire harness 30. One end of the wire harness 30 is connected to the first connector 10, and the other end of the wire harness 30 is connected to the second connector 20.

[0036] The wiring harness 30 has a first wiring harness 31 and a second wiring harness 32 that are not electrically connected. The first wiring harness 31 has a plurality of first conductors 33, which are connected in parallel through a first conductive element 40. The second wiring harness 32 has a plurality of second conductors 34, which are connected in parallel through a second conductive element 41.

[0037] The first wire harness 31 and the second wire harness 32 are arranged side by side vertically, a plurality of the first conductors 33 are arranged side by side horizontally, and a plurality of the second conductors 34 are arranged side by side horizontally. For example, there are six first conductors 33 and six second conductors.

[0038] After removing part of the insulation sheath 331 from each of the first conductors 33, a notch 332 is formed. The core wire 333 inside the first conductor 33 is exposed in the corresponding notch 332. The notches 332 are connected to form a receiving groove 35. The first conductive element 40 is disposed in the receiving groove 35 and is electrically connected to the core wire 333 so that the first conductors 33 are connected in parallel. By setting the receiving groove 35, the first conductive element 40 is disposed in the receiving groove 35, which facilitates the electrical connection between the first conductive element 40 and the core wire 333. The structure is compact and occupies little space.

[0039] The notch 332 is an annular notch 332, which surrounds the core wire 333. The first conductive element 40 has several interconnected cylindrical portions 401, and the core wire 333 passes through the corresponding cylindrical portions 401. The cylindrical portions 401 are pressed or welded to the core wire 333. The first conductive element 40 can be made of copper, aluminum, or silver. In actual production, the first conductive element 40 is first placed in the receiving groove 35. After being pressed, the first conductive element 40 forms a cylindrical portion 401 covering the outside of the core wire 333. By using the annular notch 332, the first conductive element 40 has several interconnected cylindrical portions 401, and the core wire 333 passes through the corresponding cylindrical portions 401. The cylindrical portions 401 are pressed or welded to the core wire 333. The first conductive element 40 has a large contact area with the core wire 333, resulting in good contact and stable current transmission.

[0040] Two adjacent cylindrical portions 401 are connected by a connecting portion 402. The cross-section of the connecting portion 402 is V-shaped, C-shaped, or straight. The cylindrical portion 401 and the connecting portion 402 are integrally formed.

[0041] The wire harness 30 is provided with an insulating ring 50, which is close to the first connector 10 and is spaced apart from the first connector 10. The insulating ring 50 covers the first conductive element 40 and the second conductive element 41. By setting the insulating ring 50 close to the first connector 10, when bundling the power connection wires, the cable tie is prevented from getting too close to the first connector 10, which prevents the first conductor 33 and the second conductor 34 from being subjected to stress for a long time, resulting in inconsistent elasticity of the conductive ends on the wire harness 30, thereby preventing uneven current. By covering the first conductive element 40 and the second conductive element 41 with the insulating ring 50, the first conductive element 40 and the second conductive element 41 are protected and insulated.

[0042] The insulating ring 50 is an insulating rubber ring, which is formed on the wire harness 30. The insulating ring 50 can also be an insulating ceramic ring.

[0043] It should be noted that the structure and installation method of the second conductive element 41 are the same as those of the first conductive element 40, so they will not be described again. In addition, when the core wire 333 is composed of multiple straight metal conductors, several tips can be provided on the first conductive element 40. The tips can be inserted into the metal conductors on the same core wire 333 to achieve fixation and electrical connection.

[0044] like Figure 6-8 As shown, in the second embodiment, the difference from the first embodiment is that the wire harness 30 between the insulating ring 50 and the first connector 10 is provided with a protective cover 60; by providing the protective cover 60, the wire harness 30 between the insulating ring 50 and the first connector 10 is prevented from bending.

[0045] The protective cover 60 is connected to the first connector 10. The protective cover 60 has an inner cavity (not shown). The insulating ring 50 and the wire harness 30 between the insulating ring 50 and the first connector 10 are all located in the inner cavity. The distance b between the end of the protective cover 60 away from the first connector 10 and the first connector 10 is no greater than 50mm, preferably no greater than 30mm. By setting the protective cover 60 to be connected to the first connector 10, and the insulating ring 50 and the wire harness 30 between the insulating ring 50 and the first connector 10 are all located in the inner cavity of the protective cover 60, and the distance b between the end of the protective cover 60 away from the first connector 10 and the first connector 10 is no greater than 50mm, the assembly structure of the protective cover 60, the first connector 10, and the insulating ring 50 is stable and compact.

[0046] The protective cover 60 has a detachably connected first housing 61 and second housing 62. Both the first housing 61 and the second housing 62 are snapped into the first connector 10. The first housing 61 and the second housing 62 form the inner cavity. Specifically, the first housing 61 and the second housing 62 are detachably connected by screws 63 (e.g., ...). Figure 10 As shown), the first housing 61 and the second housing 62 can also be detachably connected by snap-fit; by setting a protective cover 60 composed of the detachably connected first housing 61 and second housing 62, both the first housing 61 and the second housing 62 are snapped into the first connector 10, making it easy to install and disassemble the protective cover 60.

[0047] The first connector 10 has a protruding edge 11 on its outer side and a slot 611 on its inner side. The protruding edge 11 and the slot 611 cooperate to make the protective cover 60 engage with the first connector 10. The first housing 61 and the second housing 62 are both provided with the slot 611.

[0048] like Figure 9-11 As shown, in the third embodiment, the difference from the first and second embodiments is that the protective cover 60 is provided with a temperature detection module 70. The temperature detection module 70 has a main control circuit board 71, and a sensor (not shown) and a light-emitting element (not shown) electrically connected to the main control circuit board 71. The light-emitting element is an LED lamp. The insulating ring 50 is provided with a first window 51 for the first conductive element 40 or the core wire 333 to be exposed. The first window 51 corresponds to the sensor. When the sensor detects different temperatures of the first conductive element 40 or the core wire 333, the light-emitting element emits different colors and / or different brightness. To ensure the proper functioning of the temperature detection module 70, the main control circuit board 71 can be directly connected to the first conductor 33 and the second conductor 34 for power supply, or an additional battery can be provided to power the temperature detection module 70 separately. The temperature detection module 70 comprises a main control circuit board 71, a sensor, and a light-emitting element. The sensor detects temperature changes in the first conductive element 40 or the core wire 333, and the light-emitting element emits light of different colors and / or brightnesses according to these temperature changes. This allows for real-time detection of the wire harness 30 temperature, facilitating direct observation by the user and effective control of the wire harness 30 temperature.

[0049] The protective cover 60 is provided with a light-transmitting plate 64 and a second window 612. The light-transmitting plate 64 is located outside the second window 612. The light-transmitting plate 64 is provided with a mark 641 corresponding to the second window 612. The mark 641 is light-transmitting and can be a logo, text, or symbol. The second window 612 corresponds to a light-emitting element. By setting up the light-transmitting plate 64 and the second window 612, and setting the light-transmitting mark 641 on the light-transmitting plate 64, the need to observe temperature changes can be met, and the user's recognition of the product can be enhanced, resulting in a good integration effect.

[0050] The main control circuit board 71 is equipped with a temperature display 72, and the protective cover 60 is equipped with a third window 613 corresponding to the temperature display 72. Specifically, the third window 613 is located on one side of the second window 612. The second window 612, the third window 613, and the light-transmitting plate 64 are all provided on the first housing 61. By setting the temperature display 72, a precise temperature value 721 can be displayed, which makes it convenient for users to understand the current specific temperature and is more intuitive.

[0051] This invention applies to graphics cards or other electronic products.

[0052] In summary, this utility model achieves stable power transmission by setting a first conductive element 40 to connect a plurality of first wires 33 on the first wire harness 31 in parallel, so that the current among the first wires 33 is uniform, and by setting a second conductive element 41 to connect a plurality of second wires 34 on the second wire harness 32 in parallel, so that the current among the second wires 34 is uniform.

[0053] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technical aspects of the present utility model shall still fall within the scope of the technical solution of the present utility model.
