Description

Technical Field

[0001] This utility model relates to the technical field of copper busbar output components, and more specifically to a copper busbar output component for new energy vehicles. Background Technology

[0002] The power architecture of new energy vehicles places higher demands on efficient and safe current transmission. With the increase in battery energy density and driving range, the demand for current transmission within the battery pack has increased significantly. Traditional wiring harnesses can no longer meet the requirements for high current and high power transmission. Copper busbars, with their high conductivity and low resistance, have become the core component for current transmission between battery modules and between the battery and the electronic control system. For example, in the connection of battery modules, copper busbars realize the electrical connection between battery cells through series or parallel connection to ensure effective current transmission.

[0003] The shortcomings of existing technology: As a high-current conductor, copper busbars may generate electromagnetic interference, which may affect sensitive electronic devices in new energy vehicles. Existing copper busbar output components cannot isolate copper busbars from each other. The current flowing in adjacent copper busbars will generate an alternating magnetic field, which will cause signal interference or voltage fluctuations. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a copper busbar output component for new energy vehicles, so as to solve the problem that the existing copper busbar output components in the background art cannot isolate the copper busbars, resulting in signal interference or voltage fluctuations.

[0005] This utility model provides the following technical solution: a copper busbar output component for new energy vehicles, including an insulating bracket, a plurality of through holes in the middle of the insulating bracket, an isolation component for installing copper busbars fixedly connected to the top of the insulating bracket, and three first connecting sleeves and two second connecting sleeves in the middle of the insulating bracket.

[0006] The isolation component includes an I-shaped connecting frame fixedly connected to the top of the insulating support. Three insulating sleeves are fixedly connected to the inner cavity of the I-shaped connecting frame, and a connecting plate is fixedly connected between two adjacent insulating sleeves.

[0007] Preferably, the three insulating sleeves are arranged at equal intervals, and each of the three insulating sleeves has a copper busbar body in its inner cavity, with limiting holes formed on the insulating sleeves.

[0008] Preferably, the eight through holes are arranged in a rectangular array, the first connecting sleeve penetrates the inner cavity of two adjacent through holes, the position of the copper busbar body corresponds to the position of the first connecting sleeve, and it penetrates the inner cavity of the first connecting sleeve.

[0009] Preferably, the bottom end of the insulating bracket is provided with three connecting grooves, and the bottom end of the copper busbar body is located in the inner cavity of the connecting grooves.

[0010] Preferably, the second connecting sleeve is located in the inner cavity of two adjacent through holes, and a reinforcing rod is provided in the inner cavity of the second connecting sleeve.

[0011] Preferably, each end of the insulating bracket is provided with a mounting plate, and a steel sleeve is inserted into the middle of the mounting plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model isolates the three copper busbar bodies by providing an isolation component, and isolates adjacent copper busbar bodies by using an insulating sleeve made of insulating material, so as to avoid mutual interference of the current flowing between the copper busbar bodies and the occurrence of short circuits. It also isolates the copper busbar body part located in the inner cavity of the insulating support by the first connecting sleeve to prevent signal interference or voltage fluctuations. At the same time, the I-shaped connecting frame improves the overall strength of the structure to withstand the impact of short-circuit current, ensuring that the structure will not deform and enabling the structure to withstand higher loads.

[0014] 2. This utility model increases the surface area of ​​the structure by opening several through holes on the surface of the insulating bracket, which promotes air convection and effectively improves the overall heat dissipation efficiency of the structure. At the same time, it acts as a buffer for the insulating bracket, reducing the possibility of the copper busbar output component being directly broken due to impact. This effectively improves the buffering effect of the insulating bracket. In addition, the high temperature generated by the copper busbar body during use can be dissipated in the cavity of the through holes, which effectively improves the heat dissipation effect of the output component. The reinforcing rod in the cavity of the second connecting sleeve increases the support strength of the insulating bracket, which effectively improves the service life of the output component.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The copper busbar output component for new energy vehicles involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] This utility model provides a copper busbar output component for new energy vehicles, such as... Figure 1 - Figure 4 As shown, the system includes an insulating support 1 with several through holes 2 in the middle. An insulating component 3 for installing copper busbars is fixedly connected to the top of the insulating support 1. Three first connecting sleeves 4 and two second connecting sleeves 5 are provided in the middle of the insulating support 1. The through holes 2 increase the surface area of ​​the insulating support 1, promote air convection, thereby effectively reducing the working temperature of the copper busbars and improving the stability and reliability of the system. At the same time, the insulating support 1 acts as a buffer, reducing the possibility of the copper busbar output components being directly damaged by impact.

[0022] Furthermore, such as Figure 1 and Figure 2 As shown, the isolation component 3 includes an I-shaped connecting frame 31 fixedly connected to the top of the insulating support 1. Three insulating sleeves 32 are fixedly connected to the inner cavity of the I-shaped connecting frame 31. A connecting plate 33 is fixedly connected between two adjacent insulating sleeves 32. The position between the insulating sleeves 32 is fixed by the connecting plate 33. The I-shaped connecting frame 31 withstands the impact of short-circuit current to ensure that the structure does not deform, so that the structure can withstand higher loads and heat dissipation requirements.

[0023] Furthermore, such as Figure 2 and Figure 3As shown, three insulating sleeves 32 are arranged at equal intervals. Each of the three insulating sleeves 32 has a copper busbar body 34 inside. Limiting holes 35 are opened on the insulating sleeves 32. Each copper busbar body 34 is provided with an insulating sleeve 32. The copper busbar body 34 is inserted into the inner cavity of the insulating sleeve 32. At the same time, the position of the copper busbar body 34 is fixed by inserting connectors or other structures into the inner cavity of the limiting holes 35. The insulating sleeves 32 are made of insulating material. The insulating sleeves 32 isolate the three copper busbar bodies 34 to avoid mutual interference of the current flowing between adjacent copper busbar bodies 34, prevent short circuits, and also prevent twisting or positional displacement of the copper busbar bodies 34 when connecting or disconnecting.

[0024] Furthermore, such as Figure 1 and Figure 2 As shown, eight through holes 2 are arranged in a rectangular array. The first connecting sleeve 4 penetrates the inner cavity of two adjacent through holes 2. The position of the copper bus body 34 corresponds to the position of the first connecting sleeve 4 and penetrates the inner cavity of the first connecting sleeve 4. The first connecting sleeve 4 isolates and protects the part of the copper bus body 34 that penetrates the inner cavity of the insulating bracket 1, and plays an isolating role between adjacent copper bus bodies 34. At the same time, the high temperature generated by the copper bus body 34 in the inner cavity of the first connecting sleeve 4 can be heat-dissipated in the inner cavity of the through hole 2, which effectively improves the heat dissipation efficiency of the output component.

[0025] Furthermore, such as Figure 1 and Figure 4 As shown, the bottom of the insulating bracket 1 is provided with three connecting grooves 6. The bottom ends of the three copper busbar bodies 34 pass through the first connecting sleeve 4 and are located in the inner cavity of the connecting grooves 6. The connecting grooves 6 restrict the position of the connecting ends on the copper busbar bodies 34, which is beneficial to the accuracy of the connection.

[0026] Furthermore, such as Figure 1 and Figure 2 As shown, the second connecting sleeve 5 is located in the inner cavity of two adjacent through holes 2. The inner cavity of the second connecting sleeve 5 is provided with a reinforcing rod 7, which increases the support strength of the insulating bracket 1 and effectively improves the service life of the output component.

[0027] Furthermore, such as Figure 1 and Figure 4 As shown, both ends of the insulating bracket 1 are provided with mounting plates 8, and a steel sleeve 9 is inserted in the middle of the mounting plate 8. The output component is installed through the mounting plate 8. During installation, the bolts and other connecting parts are inserted into the inner cavity of the steel sleeve 9 to reduce the wear of the bolts on the mounting plate 8.

[0028] The working principle of this utility model is as follows: The copper busbar body 34 in the output component is first fixed to the insulating support 1 by the I-shaped connecting frame 31. Simultaneously, an insulating sleeve 32 is fitted onto the surface of each copper busbar body 34. The insulating sleeve 32 isolates adjacent copper busbar bodies 34, preventing interference between the currents flowing between them and preventing short circuits. It also prevents twisting or positional displacement of the copper busbar bodies 34 during connection and disconnection. Furthermore, the I-shaped connecting frame 31 can withstand short-circuit current impacts, ensuring structural stability and enabling the structure to withstand higher loads. During the use of the output component, The through holes 2 on the surface of the insulating bracket 1 increase the heat dissipation efficiency of the structural surface. At the same time, the copper busbar body 34 located in the inner cavity of the insulating bracket 1 is isolated by the first connecting sleeve 4 to prevent signal interference or voltage fluctuations. The high temperature generated by the copper busbar body 34 in the inner cavity of the first connecting sleeve 4 is dissipated internally in the through holes 2, which effectively improves the heat dissipation efficiency of the output component. The I-shaped connecting frame 31 and the reinforcing rod 7 increase the support strength and impact resistance of the output component. During installation, the bolts and other connecting parts are fixed by the steel sleeve 9, which reduces wear between the bolts and the insulating bracket 1 and effectively improves the service life of the output component.
