The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0025] Reference below Figure 1 The conductive connector 100 according to the embodiment of the utility model can be configured as a copper busbar for connecting the power of the three-phase wiring harness of the motor of the new energy electric drive system. However, the utility model is not limited thereto and no specific limitation is made here.
[0026] like Figure 1 As shown, the conductive connection part 30 according to the embodiment of the utility model includes: a first electrical connection end 10, a second electrical connection end 20 and a plurality of electrical connection parts 30, the first electrical connection end 10 and the second electrical connection end 20 are opposite and spaced apart, the plurality of electrical connection parts 30 are connected between the first electrical connection end 10 and the second electrical connection end 20, and at least two adjacent electrical connection parts 30 are spaced apart.
[0027] Among them, the first electrical connection end 10, the second electrical connection end 20 and the multiple electrical connection parts 30 can be integrally cast or stamped from materials such as beryllium copper, T2 copper (copper-silver alloy). Beryllium copper and T2 copper materials are easy to cast or stamp, and are easy to process, thereby reducing the manufacturing cost of the conductive connector 100. In addition, beryllium copper and T2 copper materials have excellent electrical conductivity, which can improve the conductivity of the conductive connector 100.
[0028] The first electrical connection end 10 and the second electrical connection end 20 can be arranged relative to each other and spaced apart, and a plurality of electrical connection parts 30 are connected between the first electrical connection end 10 and the second electrical connection end 20. For example, there can be two, three, four, etc. electrical connection parts 30, but the utility model is not limited thereto. There can also be other numbers of electrical connection parts 30, as long as there are multiple electrical connection parts 30. And the plurality of electrical connection parts 30 can be integrally formed with the first electrical connection end 10 and the second electrical connection end 20. And at least two adjacent electrical connection parts 30 are spaced apart. For example, there can be two, three, four, etc. adjacent electrical connection parts 30 spaced apart, but the utility model is not limited thereto. There can also be other numbers of adjacent electrical connection parts 30 spaced apart, as long as at least two adjacent electrical connection parts 30 are spaced apart. The spaced apart arrangement of two adjacent electrical connection parts 30 can make the air circulation between the adjacent electrical connection parts 30 better, thereby improving the heat dissipation effect of the conductive connector 100.
[0029] The corrosion resistance of the conductive connector 100 can be improved through passivation, tin plating and other processes, and the first electrical connection end 10 and the second electrical connection end 20 can be reasonably set and the amount of copper busbar can be adjusted according to actual conditions to prevent the ends from overheating and failure, thereby improving the safety and reliability of the conductive connector 100.
[0030] Therefore, by integrally casting or stamping the first electrical connection terminal 10, the second electrical connection terminal 20 and the plurality of electrical connection parts 30, the manufacturing cost of the conductive connector 100 can be reduced, and the conductivity of the conductive connector 100 can be improved. In addition, the plurality of electrical connection parts 30 are connected between the first electrical connection terminal 10 and the second electrical connection terminal 20, and the two adjacent electrical connection parts 30 are spaced apart, which can increase the specific surface area of the conductive connector 100, ensure the layout advantage, reduce the influence of the skin effect on the conductive connector 100, and improve the heat dissipation effect of the conductive connector 100.
[0031] According to the conductive connector 100 of the embodiment of the utility model, a plurality of electrical connection parts 30 are connected between the first electrical connection end 10 and the second electrical connection end 20, so there is no need to increase the fixing points of a single electrical connection part 30, thereby reducing the structural complexity of the conductive connector 100 and further reducing the manufacturing cost of the conductive connector 100. It can also enable the conductive connector 100 to form a larger surface area, thereby increasing the specific surface area of the copper bar, ensuring the layout advantage, reducing the influence of the skin effect on the conductive connector 100, and at least two adjacent electrical connection parts 30 are arranged to be spaced apart, which can also improve the heat dissipation effect of the conductive connector 100.
[0032] According to some embodiments of the present invention, Figure 1 As shown, the multiple electrical connection parts 30 can be parallel to each other so that the multiple electrical connection parts 30 form a copper bar, thereby increasing the specific surface area of the conductive connector 100, ensuring the layout advantage, and further reducing the influence of the skin effect on the conductive connector 100.
[0033] According to some embodiments of the present invention, Figure 1 As shown, the first direction can be Figure 1 The X direction in the second direction can be Figure 1 In the Y direction, the first direction is perpendicular to the second direction, the first electrical connection end 10 and the second electrical connection end 20 can be opposite and spaced apart along the first direction, and a plurality of electrical connection parts 30 can be arranged in sequence along the second direction, and two adjacent electrical connection parts 30 are spaced apart to form a gap, thereby accelerating the dissipation of heat between the two adjacent electrical connection parts 30, thereby improving the heat dissipation effect of the electrical connector.
[0034] According to some embodiments of the present invention, Figure 1As shown, along the second direction, the width dimension of the gap can be D1, satisfying the relationship: 0.8mm≤D1≤1.1mm, that is, the width dimension D1 of the gap can be any value between 0.8mm-1.1mm, for example: the width dimension D1 of the gap can be 0.8mm, 0.81mm, 0.82mm, 0.9mm, 1.0mm, 1.1mm and other values, but the utility model is not limited thereto, the width dimension D1 of the gap can also be other values between 0.8mm-1.1mm, as long as the width dimension D1 of the gap can be a value between 0.8mm-1.1mm. Such a setting can increase the specific surface area of the conductive connector 100, thereby reducing the skin effect of the conductive connector 100, and can also reduce the copper material and reduce the manufacturing cost of the conductive connector 100.
[0035] According to some embodiments of the present invention, Figure 1 As shown, the structures of the multiple electrical connection parts 30 can be the same. Specifically, the multiple electrical connection parts 30 can all be the same strip shape, and the conductive connector 100 has strong plasticity, and the electrical connection part 30 can be processed into various special-shaped structures to ensure the layout advantage. For example: the cross-sectional area of the electrical connection part 30 can be rectangular, square, circular, diamond-shaped, etc., but the utility model is not limited to this. The cross-sectional area of the electrical connection part 30 can also be other shapes, as long as the structures of the multiple electrical connection parts 30 are the same. Therefore, the multiple electrical connection parts 30 are the same strip structure, which can increase the specific surface area of the conductive connector 100, thereby reducing the skin effect of the conductive connector 100, and can also improve the heat dissipation effect of the conductive connector 100.
[0036] According to some embodiments of the present invention, Figure 1 As shown, along the second direction, the width dimension of the electrical connection part 30 can be D2, satisfying the relationship: 1.5mm≤D2≤2mm, that is, the width dimension D1 of the electrical connection part 30 can be any value between 1.5mm-2mm, for example: the width dimension D1 of the electrical connection part 30 can be 1.5mm, 1.5mm, 1.6mm, 1.61mm, 1.7mm, 2mm and other values, but the utility model is not limited thereto, the width dimension D1 of the electrical connection part 30 can also be other values between 1.5mm-2mm, as long as the width dimension D1 of the electrical connection part 30 can be a value between 1.5mm-2mm. In this way, while ensuring the performance of the conductive connector 100, the specific surface area of the conductive connector 100 can also be increased, thereby reducing the skin effect of the conductive connector 100.
[0037] According to some embodiments of the present invention, Figure 1As shown, the thickness dimension of the conductive connector 100 can be D3, satisfying the relationship: 2mm≤D3≤4mm, that is, the thickness dimension D1 of the conductive connector 100 can be any value between 2mm-4mm, for example: the thickness dimension D1 of the conductive connector 100 can be 2mm, 2.1mm, 2.2mm, 3mm, 3.5mm, 4mm and other values, but the utility model is not limited thereto, the thickness dimension D1 of the conductive connector 100 can also be other values between 2mm-4mm, as long as the thickness dimension D1 of the conductive connector 100 can be a value between 2mm-4mm. Such a setting is conducive to increasing the specific surface area of the conductive connector 100 while ensuring the performance of the conductive connector 100, thereby reducing the skin effect of the conductive connector 100.
[0038] According to some embodiments of the present invention, Figure 1 As shown, the first electrical connection terminal 10, the second electrical connection terminal 20 and the plurality of electrical connection parts 30 can be integrally formed. Specifically, the first electrical connection terminal 10, the second electrical connection terminal 20 and the plurality of electrical connection parts 30 can be integrally cast or stamped from materials such as beryllium copper, T2 copper (copper-silver alloy), etc., which is simple to process, thereby reducing the manufacturing cost of the conductive connector 100. In addition, beryllium copper and T2 copper materials have excellent electrical conductivity, which can improve the electrical conductivity of the conductive connector 100.
[0039] According to some embodiments of the present invention, Figure 1 As shown, both the first electrical connection end 10 and the second electrical connection end 20 may be formed with an assembly hole 40 , and the conductive connector 100 may be assembled and fixed to the corresponding component by a fixing member passing through the assembly hole 40 , thereby improving the assembly stability of the conductive connector 100 .
[0040] According to some embodiments of the present invention, Figure 1 As shown, the assembly hole 40 may be a bar hole, a circular hole, a waist hole, etc., but the present invention is not limited thereto. The assembly hole 40 may also be a hole of other shapes, which is not specifically limited here. The present application takes the assembly hole 40 as a bar hole as an example for explanation.
