Description

Technical Field

[0001] This invention relates to the field of electrical connection technology, and more specifically to a conductive connector. Background Technology

[0002] Lithium-ion batteries are widely used in power tools due to their advantages in energy density and zero emissions. However, the performance of lithium-ion batteries is greatly affected by temperature, and the operating temperature has a significant impact on the safety of the connector terminals and the battery itself.

[0003] A significant amount of heat is generated during battery charging and discharging. If this heat is not effectively dissipated, the temperature of the conductive connector surface will rise rapidly through heat transfer. This not only affects battery life but also leads to poor contact on the conductive connector surface and may even cause safety issues such as thermal runaway. More seriously, thermal runaway can cause fires and explosions, resulting in severe consequences. However, in existing technologies, traditional battery connector terminals are mostly solid metal sheets or simple spring structures with limited heat dissipation area. Heat easily accumulates at the connection point, forming localized hot spots. Summary of the Invention

[0060] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0063] Example 1

[0064] like Figures 1 to 3 As shown, this embodiment provides a conductive connector, which includes a first electrical connector 110, including a first clamping outer arm 111 and a second clamping outer arm 112. The first clamping outer arm 111 and the second clamping outer arm 112 elastically contact each other to form a first opening 113 for inserting an external connector. A second electrical connector 120 includes a first clamping inner arm 121 and a second clamping inner arm 122. The first clamping inner arm 121 and the second clamping inner arm 122 elastically contact each other to form a second opening 123 for inserting an external connector, and the orientations of the first opening 113 and the second opening 123 coincide. The first clamping outer arm 111 and the second clamping outer arm 112 are respectively provided with a first heat dissipation hole 130 and a second heat dissipation hole 131. The first clamping inner arm 121 and the second clamping inner arm 122 extend outward from the groove walls of the first heat dissipation hole 130 and the second heat dissipation hole 131, respectively.

[0065] The external connector can sequentially enter the first opening 113 and the second opening 123, and be electrically connected to the first electrical connector 110 and the second electrical connector 120.

[0066] The conductive connecting piece 100 is specifically used in power tools, and can also be used in electric vehicles and other fields that require charging of the battery 300. The first electrical connector 110 and the second electrical connector 120 are used to clamp external connectors (not shown in the figure). When the conductive connecting piece is clamped to the external connector (electrically connected), the battery 300 can be charged or discharged. By providing a first heat dissipation hole 130 and a second heat dissipation hole 131 in the first electrical connector 110, and extending the clamping inner arm of the second electrical connector 120 from there, a double-layer heat dissipation structure is formed inside the conductive connecting piece, which increases the heat dissipation surface area and promotes air circulation. This can quickly conduct and dissipate the heat generated by the contact resistance, effectively avoiding the formation of local high-temperature hot spots, thereby significantly reducing the risk of increased contact resistance due to overheating of the terminals, and fundamentally improving the safety of the electrical connection parts.

[0067] like Figures 1 to 3 As shown, in this embodiment, the first electrical connector 110 and the second electrical connector 120 also include a first pin 140 and a second pin 141 extending downward, respectively. The top of the first electrical connector 110 and the second electrical connector 120 away from the first opening 113 are connected by an arc-shaped connecting piece 142, and the top of the arc-shaped connecting piece 142 is provided with a mounting hole 150.

[0068] The first pin 140 and the second pin 141 are used for electrical connection to the battery 300. The connection methods include bolt connection, welding, crimping, etc.

[0069] Example 2

[0070] Traditional cooling systems often lack integrated airflow channels, and can only dissipate heat from terminals or batteries separately. They cannot work together to cool down individual heat-generating components, resulting in chaotic airflow and poor heat dissipation.

[0071] like Figures 4 to 7 As shown, this embodiment provides a conductive connector, including: a conductive connector 100 as in Embodiment 1; an insulating base body 200 for fixing the conductive connector 100, the insulating base body 200 being provided with a plurality of positioning grooves 210, the conductive connector 100 being disposed in the positioning grooves 210; at least one battery 300, the insulating base body 200 being disposed on the top surface of the battery 300, the conductive connector 100 being electrically connected to the battery 300; a terminal heat dissipation system 400 for heat dissipation of the conductive connector 100; and an air duct system 500 disposed on the surface of the battery 300 for providing heat dissipation channels for heat dissipation of the surface of the battery 300 and for heat dissipation of the conductive connector 100.

[0072] The conductive connector is specifically used in power tools, and can also be used in electric vehicles and other fields that require charging of the battery 300. The insulating base body 200 has eight positioning slots 210, and a conductive connecting piece 100 is installed in each positioning slot 210. The left and right ends of the insulating base body 200 are provided with fixing seats 220 and downwardly connected fasteners 230. The fasteners 230 can be connected to the surface of the battery 300 by means of bonding or welding. Battery 300 is a rechargeable lithium battery 300, or it can be other rechargeable batteries 300; terminal heat dissipation system 400 directly provides air cooling for conductive connecting piece 100. Since conductive connecting piece 100 and battery 300 are integrated and share a heat dissipation channel, and the position of conductive connecting piece 100 is below that of battery 300, when only air duct system 500 is used for heat dissipation, the airflow to battery 300 may carry some heat to the area of ​​conductive connecting piece 100. Therefore, when only air duct system 500 is used for air cooling, the air cooling effect of conductive connecting piece 100 will be poor. Therefore, terminal heat dissipation system 400 can provide air cooling for conductive connecting piece 100 alone to ensure stable heat dissipation efficiency of conductive connecting piece 100. The air duct system 500 can specifically cool the surface of the battery 300. By using a zigzag air duct, it is beneficial to increase the contact time and area of ​​the air on the surface of the battery 300, further increasing the heat dissipation area of ​​the air cooling on the surface of the battery 300, which is conducive to improving the heat dissipation effect. At the same time, it unifies and integrates the air duct path between the battery 300 and the conductive connecting piece 100, which helps to prevent air duct disorder, improve heat dissipation efficiency, and save space utilization.

[0073] like Figure 11 As shown, in this embodiment, the terminal heat dissipation system 400 includes a nozzle heat dissipation fixing mechanism, which includes:

[0074] like Figure 7 or Figure 8 As shown, the nozzle fixing mechanism 410 is provided on the fixing hole 240 on the top of the insulating base body 200, and is used to fix the conductive connecting piece 100 in the positioning groove 210 of the insulating base body 200.

[0075] like Figure 11 As shown, the multi-port pipe 420 includes several outlet pipes 421 connected in series and an inlet pipe 422 that connects all the outlet pipes. The nozzle fixing mechanism 410 is detachably connected to the outlet end of the outlet pipe 421.

[0076] like Figure 11 As shown, the first fan 423 has its output end connected to the inlet end of the outlet pipe 421 via a funnel 424.

[0077] like Figures 7 to 11As shown, the nozzle fixing mechanism 410 has two functions: First, by connecting the fixing hole 240 and the mounting hole 150 with threads, the conductive connecting piece 100 can be fixed in the insulating base body 200, which is conducive to fixing. At the same time, the detachable connection means that when a conductive connecting piece 100 malfunctions and needs to be replaced, only the corresponding nozzle fixing mechanism 410 needs to be removed to complete the disassembly. Second, it has the function of a ventilation duct, which allows the air cooling of the first fan 423 to directly contact the conductive connecting piece 100. Independent air cooling is beneficial to heat dissipation.

[0078] The number of outlet pipes 421 in the multi-channel pipe 420 is eight, corresponding to eight conductive connecting pieces 100. The inlet pipe 422 is connected to the first fan 423 through the funnel 424, which is beneficial to the heat dissipation effect.

[0079] like Figures 8 to 10 As shown, in this embodiment, the nozzle fixing mechanism 410 includes, from top to bottom, the following components:

[0080] L-shaped pipe 411, the inlet end of L-shaped pipe 411 is connected to the outlet end of outlet pipe 421, and the inner wall of the circumferential surface of the outlet end of L-shaped pipe 411 extends into a protruding ring 412 towards the shaft core.

[0081] Rotate the sheet metal 413, the axial direction of the sheet metal 413 is through, and the upper end of the sheet metal 413 is provided with a ring part 414 that is adapted to the convex ring 412.

[0082] Threaded cylindrical part 416, the threaded cylindrical part 416 is axially through, its upper end is fixedly connected to the bottom end of the rotating sheet metal 413, and its lower end is threadedly connected to the fixing hole 240.

[0083] The movable clamping part 417 has an axial through-hole and is provided with an internal thread. The threaded cylindrical part 416 is threadedly connected to the movable clamping part 417. The outer wall of the movable clamping part 417 is provided with a handle 415.

[0084] like Figures 8 to 10 As shown, the L-shaped pipe 411 is used to provide an air-cooling channel. The convex ring 412 and the L-shaped pipe 411 are an integral structure. The convex ring 412 contacts the rotating sheet metal 413. The rotating sheet metal 413 can rotate in the L-shaped pipe 411, which is convenient for manual tightening or loosening of the threaded cylindrical part 416. However, when it is necessary to tighten the nozzle fixing mechanism 410, it is only necessary to manually tighten the rotating sheet metal 413. Finally, the movable clamping part 417 is tightened manually, which is beneficial for adjusting the height of the nozzle fixing mechanism 410 and can also further tighten it to prevent gas leakage.

[0085] like Figure 5 , Figure 6 or Figure 12As shown, in this embodiment, the air duct system 500 includes:

[0086] The wind direction guiding mechanism 510 includes a plurality of first straight plates 511, a plurality of inclined plates 512 and a plurality of second straight plates 513. All the first straight plates 511 are equally spaced on one end of the surface of the battery 300, and all the second straight plates 513 are equally spaced on the other end of the surface of the battery 300. The distance between adjacent second straight plates 513 is less than the distance between adjacent first straight plates 511. The outlet of the airflow channel formed by the inclined plates 512 is connected to the inlet of the airflow channel formed by the first straight plates 511, and the inlet of the inclined plates 512 is connected to the outlet of the airflow channel formed by the second straight plates 513.

[0087] like Figure 5 , Figure 6 or Figure 12 As shown, the second fan 514 is used to dissipate heat for the battery 300, and the outlet of the second fan 514 faces and abuts the inlet of the airflow channel formed by the second straight plate 513.

[0088] The wind direction guiding mechanism 510, consisting of a first straight plate 511, an inclined plate 512, and a second straight plate 513, forms a zigzag-shaped guiding unit. Two adjacent guiding units form a duct unit, and multiple duct units together form the duct frame of the wind direction guiding mechanism 510. Each inclined plate 512 changes its inclination according to its position. From a top-down view, the overall shape of all inclined plates 512 is fan-shaped. Each battery 300 has at least one wind direction guiding mechanism 510. Each wind direction guiding mechanism 510 has a second fan 514 at the inlet to provide air cooling. Combined with the airflow guiding effect of the guide plate 515, this further ensures the working life and safety of the battery pack 300.

[0089] It should be noted that the wind direction guiding mechanism 510 is made of heat dissipation materials, such as heat sinks.

[0090] like Figure 12 As shown, in this embodiment, the wind direction guiding mechanism 510 further includes a guide plate 515 that is inclinedly disposed on one side of the inclined plate 512 for guiding and diverting airflow. The end of the guide plate 515 near the second straight plate 513 is higher than the end near the first straight plate 511.

[0091] Each air duct unit is equipped with a guide plate 515, which ensures that the airflow above the duct can be guided downward through the guide plate 515, thereby increasing the air pressure in contact with the battery 300 and achieving a better overall heat dissipation effect under the same air volume.

[0092] like Figure 12As shown, optionally, the oblique ventilation holes 516 are provided on the second straight plate 513. Within the range of the second straight plate 513, the air of each channel unit can flow downward through the oblique ventilation holes 516, which can act as a guide plate 515 and further enhance the heat dissipation effect.

[0093] like Figure 12 As shown, in this embodiment, the wind direction guiding mechanism 510 further includes a support crossbar 517 disposed on the first straight plate 511. The support crossbar 517 is provided with a plurality of fixed through slots 518, and the plurality of fixed through slots 518 correspond to a plurality of conductive connecting pieces 100.

[0094] The support crossbar 517 provides a fixed platform for the wind direction disturbance mechanism 520, and each fixed through slot 518 corresponds to a conductive connecting piece 100.

[0095] like Figure 13 As shown, in this embodiment, the air duct system 500 includes:

[0096] The wind direction disturbance mechanism 520 is installed on the fixed through groove 518 and is used to generate turbulence in the airflow. The wind direction disturbance mechanism 520 includes a bearing 521 installed on the fixed through groove 518, a support rod 522 connected inside the bearing 521, and a plurality of blades 523 installed on the support rod 522.

[0097] Because the conductive connecting piece 100 has multiple curved surfaces with different curvatures, such as the first electrical connector 110, the second electrical connector 120 and the curved connecting piece 142; or, it has multiple straight planes that are parallel to the airflow direction and perpendicular to the battery 300 plane, such as the first pin 140 and the second pin 141; therefore, when a single DC airflow flows through the various surfaces of the conductive connecting piece 100, it will produce a partial slight contact or no contact effect, and cannot completely cover any dead corners, resulting in inconsistent heat dissipation effects on different planes.

[0098] like Figure 13 As shown, the support rod 522 can rotate through the bearing 521. By setting multiple vanes 523 at both ends of the support rod 522 according to the circumferential distribution of its axis, the wind drives the vanes 523 to rotate, thereby disturbing the airflow direction.

[0099] like Figure 5 As shown, the wind direction disturbance mechanism 520 can specifically disturb the wind direction at the air outlet end of the wind direction guiding mechanism 510, so that when the air flows through each end face of the conductive connecting piece 100, it generates air cooling in different directions, which can further make the air cooling effect on each end face, and the heat dissipation effect of different planes is consistent.

[0100] like Figure 14 or Figure 15 As shown, in this embodiment, the conductive connector also includes a housing 600, which includes a plug-in plate 610. The plug-in plate 610 has ventilation straight pipes 620 at both ends, and the outer walls of the two ventilation straight pipes 620 are provided with guide rail grooves 630.

[0101] By deeply integrating the heat dissipation function into the insulating base body 200, terminal fixing structure, and housing 600, this invention achieves dual high-efficiency heat dissipation while avoiding the redundancy of external heat dissipation modules. The connection design between the ventilation straight duct 620 and the internal air duct makes the entire conductive connector structure more compact and neat.

[0102] In summary, the present invention provides a conductive connecting piece and a conductive connecting base. 1. By providing heat dissipation through holes on the first electrical connector 110 and extending the clamping inner arm of the second electrical connector 120 from there, the heat dissipation area of ​​the conductive connecting piece is increased, and a double-layer heat dissipation structure that promotes air circulation can quickly conduct and dissipate the heat generated by the contact resistance, effectively avoiding the formation of local high-temperature hot spots.

[0103] 2. By designing the terminal heat dissipation system 400 and the air duct system 500, the heat dissipation direction of the battery 300 and the terminal is synchronously integrated, making the air duct orderly, preventing the air direction from being disordered, and enabling the heat of the target to be effectively discharged; at the same time, the two systems respectively provide targeted heat dissipation for the target heat-generating parts, thereby improving heat dissipation efficiency.

[0104] Working principle overview:

[0105] When the conductive connector is in operation, the battery 300 generates heat during charging and discharging, and the conductive connecting pieces also heat up due to the transmission of large currents. At this time, the first fan 423 and the second fan 514 are activated. The second fan 514 drives the airflow through the airflow guide mechanism 510 to specifically remove the heat from the surface of the battery 300, and finally the airflow disturbance mechanism 520 converts it into a highly efficient heat-dissipating turbulent flow, which evenly sweeps across the entire surface of the conductive connecting pieces, removing the heat from the conductive connecting pieces. At the same time, the cool air driven by the first fan 423 is precisely blown onto the heat-generating parts of each conductive connecting piece through the nozzle heat dissipation fixing mechanism, especially the heat dissipation through-hole areas, to enhance cooling. The two airflows work together inside the conductive connector without interfering with each other, complementing each other. Finally, the hot air is discharged through the ventilation straight duct 620 of the housing 600, thereby achieving efficient, uniform, and reliable heat dissipation management for the entire conductive connector system.

[0106] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
