[0002] Copper busbars and flat plugs are widely used in electrical connection devices due to their ease of installation and reliable current transmission. This is particularly true in vehicles, industrial equipment, and power systems, where these structures carry significant power transmission responsibilities. Their stability and safety are crucial to overall system reliability. To adapt to diverse operating conditions, the design of copper busbars and flat plugs must not only ensure a reliable electrical connection but also enhance their waterproof performance to ensure proper functionality in high humidity or submerged environments.

[0003] At present, the common joint sealing method on the market directly adopts the rubber coating process to ensure the waterproof performance of the copper busbar flat plug structure. However, the rubber coating process is complicated and the surface of the copper busbar is smooth. The copper busbar will inevitably shake during the insertion into the shell. The shaking of the copper busbar can easily cause a gap between the sealing ring or sealing sleeve and the shell, resulting in a decrease in the overall waterproof performance. Utility Model Content

[0043] Please refer to Figure 5 , Figure 5As shown in the structural schematic diagram of the sealing assembly and the copper bar, the sealing assembly 2 is composed of a support 21 and a sealing ring 22, the support 21 is made of plastic and has a "mouth" shape and is sleeved on the copper bar 1, the sealing ring 22 is made of rubber and is sleeved on the surface of the support 21, the surface of the support 21 is provided with a groove matched with the sealing ring 22 to fix the sealing ring 22. Since the copper bar 1 is stamped and formed and has an irregular shape, the sealing ring 22 is soft and is prone to twisting and deforming between the shell 4 and the copper bar 1, so that the sealing ring 22 cannot completely match the surface of the copper bar 1 and cannot achieve the best waterproof effect. The sealing ring 22 is sleeved on the surface of the support 21 to increase the matching of the sealing ring 22, the support 21 fixes and supports the sealing ring 22 to prevent the sealing ring 22 from twisting and deforming, and the waterproof performance of the independent waterproof copper bar flat plug structure is more stable.

[0044] The surface of the copper bar 1 is further provided with a limiting hole 13, the contact surface of the support 21 and the copper bar 1 is provided with a limiting column 211 matched with the limiting hole 13 to further limit the support 21 and enhance the stability of the waterproof structure to prevent the sealing element from twisting between the shell 4 and the copper bar 1. The copper bar 1 is further provided with two limiting grooves 14 matched with the limiting assembly 3, the limiting grooves 14 are located on both sides of the sealing assembly 2 to support the sealing assembly 2 at two points and enhance the stability of the internal structure of the independent waterproof copper bar flat plug structure to prevent the sealing assembly 2, the copper bar 1 and the shell 4 from twisting. The limiting assembly 3 on one side of the principle electric connection terminal 11 is provided with a plurality of wire passing holes 31, the gap between the limiting assembly 3, the copper bar 1 and the sealing assembly 2 can be provided with a temperature sensor, and the cable connected with the temperature sensor can pass out of the wire passing hole 31 on the limiting assembly 3.

[0045] Please see Figure 6 , Figure 6 As shown in the limiting structure schematic diagram of the shell, the shell 4 is provided with a clamping groove 41 on the upper and lower surfaces of the inner wall near one end of the electric connection terminal 11, the electric connection terminal 11 is provided with a spring sheet 111, the spring sheet 111 is bent away from the surface of the copper bar 1, one end of the spring sheet 111 is bent is the end of the electric connection terminal 11 near the entrance of the shell 4, the spring sheet 111 is matched with the clamping groove 41, when the copper bar 1 is in the shell 4, a pulling force is applied to the copper bar 1 in the direction of the spring sheet 111, the spring sheet 111 abuts against the clamping groove 41 to prevent the copper bar 1 from falling off from the shell 4. The entrance of the shell 4 is further provided with a stop groove 43, the sealing assembly 2 near the entrance of the shell 4 is provided with a stop block 32 matched with the stop groove 43, when the copper bar 1 is inserted into the shell 4 from the entrance of the shell 4, the stop block 32 abuts against the stop groove 43, the copper bar 1 reaches the limit position, at this time, the spring sheet 111 is bent to abut against the clamping groove 41, the stop groove 43 and the clamping groove 41 jointly limit the copper bar 1 to fix the copper bar 1 in the shell 4.

[0046] The tail of the shell 4 is provided with a disassembly hole 42, which is connected with the locking groove 41, and there is a gap between the electric connection terminal 11 and the shell 4. When it is necessary to disassemble the shell 4 and the copper bar 1 assembly, the disassembly thimble is inserted into the shell 4 from the disassembly hole 42, and is moved to the position where the elastic sheet 111 is located along the gap between the electric connection terminal 11 and the shell 4. The disassembly thimble forces the elastic sheet 111 to move towards the copper bar 1, so that the elastic sheet 111 cannot abut against the locking groove 41, thereby enabling the copper bar 1 to be separated from the shell 4. One end of the bottom of the shell 4 is a double-shell structure, and the outer shell is provided with a through hole 44 corresponding to the interval position away from the electric connection terminal 11. Other copper bars 1 can pass through the through hole 44 and contact the electric connection terminal 11.

When the stop block 32 of the sealing assembly 2 abuts against the stop groove 43 of the shell 4, the copper bar 1 moves to the limit position. At this time, the elastic sheet 111 of the electric connection terminal 11 is popped out and abuts against the locking groove 41, so that the copper bar 1 is fixed in the shell 4. The contact surfaces of the sealing assembly 2 and the limiting assembly 3 with the copper bar 1 are sealed with glue, which increases the waterproof effect of the independent waterproof copper bar flat plug structure. The sealing assembly 2 seals the independent waterproof copper bar flat plug structure, so that the independent waterproof copper bar flat plug structure can be effectively waterproofed. The limiting assembly 3 is between the copper bar 1 and the shell 4, which prevents the copper bar 1 and the shell 4 from being twisted. The structure of the independent waterproof copper bar flat plug structure is more stable and will not have gaps due to twisting.

[0048] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
