[0031] Reference Figure 1 , Figure 2 , Figure 4An integrated connection device for high-current transmission and waterproofing is disclosed. It comprises several universal modules housed within a metal housing 2 and several crimp terminals 5 disposed outside the metal housing 2. Each universal module includes a busbar 6 and a conductive spring 7 at the bottom of the busbar 6. The busbar 6 connects the crimp terminals 5 and the conductive spring 7. The use of the busbar 6 and conductive spring 7 within the metal housing 2 enables high-current transmission, satisfying the requirement of high-current propagation even in confined spaces. This is achieved through the integrated design of a high-current connector, where multiple busbars 6 and conductive springs 7 on a single connector form a universal module. Furthermore, the use of the busbar 6 and conductive springs 7 increases the current while simultaneously enabling the busbar 6 and conductive springs 7 to be assembled and disassembled together as a universal module, connected within the metal housing 2 to the crimp terminals 5 located outside the metal housing 2. In addition, an upper insulator 3 and a lower insulator 4 are respectively provided at both ends of the universal module inside the metal housing 2. The crimp terminal 5 passes through the metal housing 2 and the upper insulator 3 and is connected to the universal module, and is used for the transmission of high current. The bottom of the universal module passes through the lower insulator 4 and is connected to the electronic equipment. The combination of the universal module, the upper insulator 3, the lower insulator 4 and the metal housing 2 forms a modular installation with a high degree of integration, saving internal space of the connection device, simplifying the difficulty of operation, and facilitating installation and maintenance.

[0032] Specifically, the universal module has an upper insulator 3 and a lower insulator 4 at both ends. The crimp terminal 5 passes through the metal housing 2 and the upper insulator 3 and communicates with the universal module, and is used for high current transmission. The bottom of the universal module passes through the lower insulator 4 and communicates with the electronic device. The metal housing 2 has an installation space inside, and a mounting hole 22 communicating with the installation space is provided at the bottom. The upper insulator 3, the universal module, and the lower insulator 4 are sequentially installed in the installation space of the metal housing 2 through the mounting hole 22. The lower insulator 4 is fixed to the metal housing 2 by a third fixing screw 43, thus fixing the upper insulator 3 and the universal module inside the metal housing 2 by the lower insulator 4. After installation, the metal housing 2 and other structures inside the metal housing 2 can be fixed to the electronic device by a second fixing screw 23 that passes through the periphery of the top of the metal housing 2. The second fixing screw 23 is a non-removable screw, which can meet the requirements of centralized installation, space saving, and convenient maintenance.

[0033] Reference Figure 3 , Figure 5 , Figure 6 , Figure 7In one embodiment of this application, the universal modules formed by the busbar 6 and the conductive spring 7 are configured in four groups. These four universal modules, when connected to the external crimp terminals 5, can transmit currents of different magnitudes. To facilitate communication between the universal modules inside the metal housing 2 and the external structure, the top of the metal housing 2 is provided with four first through holes 21 for communication between the crimp terminals 5 and the busbar 6. The four crimp terminals 5 pass through the first through holes 21 and connect to the universal modules. The upper insulator 3, located between the metal housing 2 and the busbar 6, is also provided with second through holes 32, the same number as the first through holes 21 and corresponding in position (upper and lower). Furthermore, an insulating bushing 31 extending towards the inner edge of the first through hole 21 is provided at the edge of the second through hole 32. The insulating bushing 31 provides insulation protection between the inner edge of the first through hole 21 and the busbar 6, ensuring the product's insulation performance. To facilitate the installation of the insulating bushing 31, the total size of the second through hole 32 and the insulating bushing 31 is equal to the size of the first through hole 21.

[0034] In this embodiment, the lower insulator 4 is further provided with four third through holes 42 for connecting the general module and the electronic device, and the positions of the third through holes 42 correspond vertically to the positions of the first through holes 21 and the second through holes 32. In addition, a limiting step 41 for limiting the busbar 6 is provided inside the third through hole 42. The bottom of the busbar 6 is stuck on the limiting step 41, and the four conductive springs 7 are respectively located in the four third through holes 42, and are in contact with the busbar 6 and the crimp terminal 5 in the third through holes 42 for conduction. At the same time, the conductive springs 7 can also be in contact with the electronic device at the bottom through the through holes 42.

[0035] Reference Figure 8 , Figure 9 In this embodiment, a limiting block 62 for limiting the conductive spring 7 is also provided at the bottom of the busbar 6. The limiting block 62 and the busbar body form a limiting groove for inserting the conductive spring 7. The limiting groove limits the conductive spring vertically and also restricts the movement of the conductive spring in part of the horizontal direction, so that the conductive spring only has movement in the insertion direction when inserted into the limiting groove relative to the busbar. Therefore, a limiting pin 61 for limiting the conductive spring 7 is also provided on the busbar 6 in the third through hole 42. The limiting pin 61 extends through the busbar 6 into the third through hole 42, which limits the displacement of the conductive spring 7 in the insertion direction in the third through hole 42, ensuring the accuracy of the connection between the conductive spring 7, the busbar 6, and the electronic equipment. It also provides limiting support for the installation of the busbar 6 and the conductive spring 7, which facilitates the formation of a universal module that can be assembled and disassembled simultaneously.

[0036] In this embodiment, the four external crimp terminals 5 are connected to the busbar 6 and the conductive spring 7 via the first fixing screw 51. The first fixing screw 51 passes through the crimp terminal 5, then through the first through hole 21, the second through hole 32 and the busbar 6, and finally crimps onto the conductive spring 7, completing the connection between the external crimp terminals 5 and the internal general module.

[0037] Reference Figure 7 In this embodiment, a waterproof sealing structure is also provided at the connection between the upper insulator 3 and the lower insulator 4 and the edge of the metal housing 2. The three-layer sealing structure, consisting of the metal housing 2 and two sealing rings, provides overall sealing for the integrated connection device, sealing between the metal housing 2 and the upper insulator 3, and sealing between the upper insulator 3 and the busbar 6, preventing water and other impurities from entering the connection structure and damaging the general module. The waterproof sealing structure includes a first sealing ring 11 between the metal housing 2 and the upper insulator 3, a second sealing ring 12 between the upper insulator 3 and the busbar 6, and a third sealing ring 13 between the metal housing 2 and the electronic device. There are four first and two second sealing rings 12, and one third sealing ring 13.

[0038] Specifically, a first mounting groove 14 for installing the first sealing ring 11 is provided on the upper insulator 3 located at the upper edge of the four second through holes 32; a second mounting groove 15 for installing the second sealing ring 12 is provided on the upper insulator 3 located at the lower edge of the four second through holes 32; and a third mounting groove 16 for installing the third sealing ring 13 is provided at the bottom of the metal housing 2 near the mounting hole 22. The three types of sealing rings provided in multiple locations can achieve waterproof sealing protection for internal parts of the connection structure when multiple connection ports are provided. Furthermore, after the integrated connection device is installed and fixed to the electronic device by the second fixing screw 23, the sealing rings are compressed and deformed, achieving a waterproof sealing function between the integrated connection device and the electronic device.

[0039] The above description is merely a preferred embodiment of this utility model. Any simple modifications, equivalent changes, and alterations made by those skilled in the art to the above embodiments without departing from the technical scope of this utility model and based on its technical essence shall still fall within the scope of this utility model.
