Description

Technical Field

[0001] The utility model relates to the technical field of electrical components, and particularly relates to a multifunctional conductive component. Background Art

[0002] A copper bar, also known as a copper busbar or a copper bus, is a flat plate-shaped conductor made of copper, which plays the role of conveying current and connecting electrical equipment in a circuit. At present, new energy vehicles have very high requirements for the stability of the electronic control system. Copper bars are widely used in the field of new energy vehicles. As a connector link, the connection stability of the copper bar itself is crucial.

[0003] Conventional copper bars are mostly like those disclosed in the publication number CN109217038B, which are usually a plate-shaped metal sheet. Since connectors usually need to conduct high-voltage and large-current, the copper bar will inevitably heat up during use, and the temperature will affect the stability and reliability of its current conduction. In addition, the structure of the conventional copper bar is simple, and its use cannot meet the requirements of complex connectors. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a multifunctional conductive component.

[0005] The purpose of the utility model is achieved by the following technical solutions:

[0006] The multifunctional conductive component includes a conductive body, an insulating layer, a shielding layer, and a protective shell that are arranged layer by layer from the inside out. The outer contours of the conductive body, the insulating layer, the shielding layer, and the protective shell are the same, and the four are laminated together layer by layer. A hollow liquid cooling channel is provided through the axis of the conductive body for circulating coolant.

[0007] Preferably, the conductive body is a flat plate-shaped or cylindrical rod-shaped.

[0008] Preferably, the conductive body is made of copper-aluminum alloy.

[0009] Preferably, the outer contour of the liquid cooling channel matches that of the conductive body.

[0010] Preferably, the insulating layer is coated on the outer wall of the conductive body.

[0011] Preferably, the shielding layer is a shielding braided net.

[0012] Preferably, the shielding layer is a hard shielding layer.

[0013] The beneficial effects of the utility model are mainly reflected in:

[0014] An insulating layer, a shielding layer and a protective shell are sleeved outside the conductive body to form an integrated unit, enabling the conductive body to have multiple functions such as conductivity, insulation, and shielding. At the same time, a liquid cooling channel is arranged inside the conductive body to allow the coolant to flow through, so that the conductive body can be internally provided with coolant to cool down in time during use and maintain its temperature constant.

However, these embodiments are not limited to the present invention, and any structural, method, or functional transformation made by those of ordinary skill in the art based on these embodiments is included in the protection scope of the present invention.

In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. And in the description of the solution, with the operator as a reference, the direction close to the operator is the proximal end, and the direction away from the operator is the distal end.

[0022] As Figures 1 to 4 shown, the present invention discloses a multifunctional conductive element, including a conductive body 1, an insulating layer 2, a shielding layer 3, and a protective shell 4 arranged layer by layer from the inside out. The outer contours of the conductive body 1, the insulating layer 2, the shielding layer 3, and the protective shell 4 are the same, and the four are laminated together layer by layer. A hollow liquid cooling channel 101 is provided through the axis of the conductive body 1 for circulating the coolant.

[0023] An insulating layer 2, a shielding layer 3 and a protective housing 4 are sleeved outside the conductive body 1 to form an integral body, so that the conductive body 1 has multiple functions such as conductivity, insulation and shielding at the same time. Meanwhile, a liquid cooling channel 101 is arranged inside the conductive body 1 to allow the coolant to flow through, so that the conductive body 1 can be internally provided with the coolant to cool down in time during use to keep its temperature constant.

[0024] Specifically, the conductive body 1 has at least two feasible embodiments. For example, Figure 1 , Figure 2 in the first embodiment and the second embodiment shown, the conductive body 1 is a flat plate; for example, Figure 3 , Figure 4 in the third embodiment and the fourth embodiment shown, the conductive body 1 is a cylindrical rod.

[0025] To ensure its good electrical conductivity, the conductive body 1 is preferably made of copper-aluminum alloy. In other feasible embodiments, the conductive body 1 can also be made of other materials with good electrical conductivity.

[0026] To expand the inner diameter of the liquid cooling channel 101 as much as possible, the outer contour of the liquid cooling channel 101 matches the conductive body 1 to improve its matching with the conductive body 1, so as to form a uniform wall thickness between it and the conductive body 1, and then produce a uniform cooling effect.

[0027] The insulating layer 2 is coated on the outer wall of the conductive body 1 to make it tightly fit with the conductive body 1, so as to ensure that it isolates the conductive body 1 from other wire cores and ensure the use safety. The insulating layer 2 can be integrally formed with the conductive body 1 by processes such as injection molding.

[0028] The shielding layer 3 has two feasible embodiments. For example, Figure 1 and Figure 3 in the first embodiment and the third embodiment shown, the shielding layer 3 is a shielding braided mesh; for example, Figure 2 and Figure 4 in the second embodiment and the fourth embodiment shown, the shielding layer 3 is a hard shielding layer, which is used to isolate the electromagnetic interference between the conductive bodies 1 and ensure the use stability.

[0029] The protective housing 4 can be a hard shell or a soft shell, which can protect the conductive body 1 from being invaded by external impurities and moisture, and can also prevent the conductive body 1 from being damaged unnecessarily by external forces.

[0030] It should be understood that although this specification is described in terms of embodiments, not every embodiment contains only an independent technical solution. This narrative style of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0031] The series of detailed descriptions listed above are only specific descriptions of the feasible embodiments of the present invention, and they are not intended to limit the protection scope of the present invention. Any equivalent embodiments or modifications made without departing from the technical spirit of the present invention should be included within the protection scope of the present invention.
