[0038] See Figures 1 to 13 As shown, this invention discloses a specific embodiment of a high-voltage connector device, including: a plug mechanism 10 and a socket mechanism 20; the plug mechanism 10 is connected to the socket mechanism 20; the plug mechanism 10 includes a socket terminal assembly 11, and the socket mechanism 20 includes a ferrule assembly 21, the socket terminal assembly 11 cooperating with the ferrule assembly 21; the plug mechanism 10 also includes a housing 12, an insulating mounting base 13, and a cable assembly 14; the insulating mounting base 13 is located inside the housing 12, and the insulating mounting base 13 has a mounting cavity 131 for accommodating the socket terminal assembly 11, the bottom of the mounting cavity 131 has an opening 132, the ferrule assembly 21 passes through the opening 132 and is connected to the socket terminal assembly 11, one end of the cable assembly 14 is located inside the mounting cavity 131 and connected to the socket terminal assembly 11, and the other end is connected to the housing 12.

[0039] Specifically, by cooperating with the socket terminal assembly 11 and the core assembly 21, both the plug mechanism 10 and the socket mechanism 20 can be disassembled, making the high-voltage connector device compatible with the functional structure of maintenance switches and connectors, facilitating maintenance and reducing maintenance costs.

[0040] Specifically, by accommodating the jack terminal assembly 11 in the mounting cavity 131, one end of the cable assembly 14 is located in the mounting cavity 131 and connected to the jack terminal assembly 11, and the other end is connected to the housing 12, resulting in a compact structure and strong sealing performance.

[0041] See Figures 1 to 10As shown, the socket terminal assembly 11 includes a left socket terminal assembly 111 and a right socket terminal assembly 112 with the same structure as the left socket terminal assembly 111. The cable assembly 14 includes a left cable assembly 141 and a right cable assembly 142 with the same structure as the left cable assembly 141. The left cable assembly 141 cooperates with the left socket terminal assembly 111, and the right cable assembly 142 cooperates with the right socket terminal assembly 112. The left socket terminal assembly 111 includes a terminal connecting portion 1111 and a spring sheet 1112. The spring sheet 1112 is located inside the terminal connecting portion 1111, and the left cable assembly 141 is connected to the terminal connecting portion 1111.

[0042] Specifically, by having the left cable assembly 141 cooperate with the left socket terminal assembly 111 and the right cable assembly 142 cooperate with the right socket terminal assembly 112, the left and right sides form independent structures, reducing the possibility of mutual interference.

[0043] See Figures 6 to 10 As shown, the terminal connection part 1111 includes a terminal housing 11111 and a connection end 11112; the spring sheet 1112 is located inside the terminal housing 11111, and the left cable assembly 141 is connected to the connection end 11112; the connection end 11112 is U-shaped and is used to clamp the left cable assembly 141.

[0044] Specifically, there are two spring plates 1112, located on both sides inside the terminal housing 11111. The connecting end 11112 is U-shaped and is used to clamp the left cable assembly 141, making the connection between the two tighter and less likely to loosen, so as to ensure stable current transmission.

[0045] Specifically, in this embodiment, the terminal housing 11111 and the connecting end 11112 are integrally formed by stamping, which reduces the overall size of the structure, while also having high strength and requiring only one set of molds for production, thus reducing production costs.

[0046] See Figures 8 to 10 As shown, the spring sheet 1112 is provided with a plurality of (at least 2) puncture portions 11121, and the terminal housing 11111 is provided with a slot 11113 corresponding to the puncture portion 11121, and the puncture portion 11121 cooperates with the slot 11113.

[0047] Specifically, by having the puncture part 11121 cooperate with the slot 11113, the spring piece 1112 will not move up and down, so that the spring piece 1112 and the terminal housing 11111 are more securely assembled.

[0048] See Figures 7 to 8As shown, the left socket terminal assembly 111 also includes a clamping member 1113, which is connected to the terminal housing 11111 to prevent the spring sheet 1112 from becoming loose from the terminal housing 11111.

[0049] See Figures 1 to 8 As shown, the left cable assembly 141 includes a cable 1411, an inner pressure ring 1412, an outer pressure ring 1413, a waterproof ring 1414, and a tail buckle 1415. One end of the cable 1411 is connected to the connecting end 11112. The inner pressure ring 1412, the outer pressure ring 1413, the waterproof ring 1414, and the tail buckle 1415 are all sleeved on the cable 1411. The outer pressure ring 1413 is located on the outer periphery of the inner pressure ring 1412. The waterproof ring 1414 is in contact with the outer pressure ring 1413. The tail buckle 1415 is in contact with the waterproof ring 1414 and cooperates with the outer shell 12.

[0050] Specifically, the inner pressure ring 1412, outer pressure ring 1413, waterproof ring 1414 and tail buckle 1415 are all sleeved on the cable 1411. The outer pressure ring 1413 is located on the outer periphery of the inner pressure ring 1412. The waterproof ring 1414 is in contact with the outer pressure ring 1413. The tail buckle 1415 is in contact with the waterproof ring 1414 and cooperates with the outer shell 12. The structure is compact and has strong sealing performance.

[0051] See Figures 7 to 8 As shown, the plug mechanism 10 also includes a metal pressure plate 15, which has a groove 151 for cooperating with the outer pressure ring 1413. The metal pressure plate 15 is connected to the outer shell 12 by screws.

[0052] Specifically, by placing the outer pressure ring 1413 on the groove 151, it serves as a limit, and then the metal pressure plate 15 is connected to the outer shell 12 by screws, so that the outer pressure ring 1413 is fastened and not easy to loosen. At the same time, the holding force of the left socket terminal assembly 111 in the insulating mounting base 13 is ensured by the clamping member 1113 and the inner pressure ring 1412, and the metal pressure plate 15 is locked after the outer pressure ring 1413 is pressed.

[0053] Specifically, in this embodiment, the metal pressure plate 15 has grooves 151 on both the left and right sides, which cooperate with the left cable assembly 141 and the right cable assembly 142 respectively.

[0054] Specifically, a sealing ring 16 is also connected to the bottom of the outer casing 12 to enhance the sealing effect.

[0055] Specifically, in this embodiment, the outer periphery of the cable 1411 is wrapped with a metal braided mesh, the outer shell 12 is made of aluminum alloy, the metal pressure plate 15 is made of stainless steel, and both the inner pressure ring 1412 and the outer pressure ring 1413 are made of metal. The cable 1411 is electrically connected to the crimped inner and outer pressure rings 1412 and 1413, then to the metal pressure plate 15, and finally to the outer shell 12. Finally, the outer shell 12 and the external enclosure achieve shielded conductivity, transmitting interference signals to the outside of the external enclosure and eliminating magnetic field interference, thus ensuring that the current transmission in the cable 1411 is not affected.

[0056] See Figures 1 to 5 and Figures 11 to 13 As shown, the socket mechanism 20 also includes a base 22 and a cover plate 23 connected to the base 22; the ferrule assembly 21 is connected to the base 22, and the ferrule assembly 21 includes a fuse 211, a first copper busbar 212, a second copper busbar 213 and a third copper busbar 214; the base 22 has a storage cavity 221 in the middle to accommodate the fuse 211 and plug-in cavities 222 on both sides; one end of the second copper busbar 212 is connected to one end of the fuse 211, and the other end is located in the left plug-in cavity 222 and connected to the spring piece 1112 of the left plug terminal assembly 111; one end of the third copper busbar 214 is connected to the other end of the fuse 211; the first copper busbar 212 is located in the right plug-in cavity 222; the upper end of the first copper busbar 212 is connected to the spring piece 1112 of the right plug terminal assembly 112; the lower end of the first copper busbar 212 and the other end of the third copper busbar 214 protrude from the base 22.

[0057] Specifically, by accommodating the fuse 211 within the storage cavity 221 and making it detachable, flexibility is improved and maintenance costs are reduced.

[0058] Specifically, the first copper busbar 212, the second copper busbar 213, and the third copper busbar 214 are injection molded onto the insulating plastic base 22 using in-mold injection molding, resulting in a robust structure that saves space. Furthermore, the first copper busbar 212, the second copper busbar 213, and the third copper busbar 214 are all designed with round holes to facilitate the intake of glue during in-mold injection molding, ensuring overall stability and preventing the copper busbars from easily detaching from the insulating plastic base 22.

[0059] Specifically, the lower end of the first copper busbar 212 and the other end of the third copper busbar 214 protrude from the base 22 for connection to an external battery pack or other components.

[0060] See Figure 13As shown, the cover plate 23 has buckle protrusions 231 on both sides, and the base 22 has a snap-fit ​​groove 223 corresponding to the buckle protrusions 231. The buckle protrusions 231 cooperate with the snap-fit ​​grooves 223.

[0061] Specifically, the buckle protrusion 231 cooperates with the snap-fit ​​groove 223 to make the connection between the cover plate 23 and the base 22 tighter and less likely to fall off.

[0062] See Figures 1 to 5 As shown, the high-voltage connector device also includes a mounting panel 30, which has an opening 31. The base 22 is located in the opening 31 and connected to the mounting panel 30, and the housing 12 is connected to the mounting panel 30.

[0063] Specifically, the socket mechanism 20 is first engaged with the mounting panel 30 and then tightened with four combination screws. Then, the plug mechanism 10 is connected to the socket mechanism 20 and tightened with four combination screws. At this time, the current passes through the core assembly 21 of the socket mechanism 20 inside the chassis, the socket terminal assembly 11 of the plug mechanism 10 outside the chassis, and the cable 1411 to achieve connection.

[0064] Specifically, after the plug mechanism 10 and the socket mechanism 20 are locked together, the sealing ring 16 cooperates with the housing and the waterproof ring 1414, the tail buckle 1415 and the outer shell 12 cooperate to achieve isolation from the outside, so that the protection reaches the IP67 level.

[0065] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.
