Detailed Implementation

[0022] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] The following is a reference to the appendix. Figures 1 to 4 This invention describes in detail the high-voltage connector socket 100, the high-voltage connector assembly, the battery pack 1000, and the vehicle according to embodiments of the present invention.

[0024] like Figure 1 As shown, the battery pack 1000 of this utility model embodiment includes a housing 200 and a high-voltage connector socket 100.

[0025] The box 200 is provided with a first through hole 2001 and a second through hole (not shown in the figure), and the box 200 has an inner wall surface and an outer wall surface.

[0026] like Figures 2 to 4 As shown, the high-voltage connector seat 100 of this embodiment includes a first flange 1, a conductive terminal 2, a second flange 3, a protective shell 4, and fasteners (not shown in the figure). The first flange 1 has the conductive terminal 2, and one side of the first flange 1 is connected to the inner wall of the housing 200. The second flange 3 has the protective shell 4 on one side, and a clearance hole 31 on the second flange 3. The conductive terminal 2 passes through the clearance hole 31, and the other side of the second flange 3 is connected to the outer wall of the housing 200. Fasteners pass through a second through hole and connect the second flange 3 and the first flange 1.

[0027] The battery pack 1000 also includes a high-voltage busbar (not shown in the figure), which is located inside the housing 200. One end of the conductive terminal 2 is provided with a threaded mounting hole 21, through which this end of the conductive terminal 2 is connected to the high-voltage busbar. The other end of the conductive terminal 2 is used to connect to a high-voltage connector plug.

[0028] like Figure 1 As shown, the installation process of the high-voltage connector base 100 and the housing 200 in this embodiment of the present invention is as follows: Method 1: First, place the first flange 1 inside the housing 200, and then connect one end of the conductive terminal 2 to the high-voltage busbar inside the battery pack 1000. Alternatively, first connect one end of the conductive terminal 2 to the high-voltage busbar, and then place the first flange 1 and the high-voltage busbar inside the housing 200. Then, move the other end of the conductive terminal 2 into the first through hole 2001 of the housing 200, so that one side of the first flange 1 abuts against the inner wall of the housing 200. Then, align the clearance hole 31 of the second flange 3 with the other end of the conductive terminal 2, and move the second flange 3 toward the housing 200, so that the other side of the second flange 3 abuts against the outer wall of the housing 200. Then, insert fasteners into the second through hole to connect the first flange 1 and the second flange 3, so that the first flange 1 and the second flange 3 are fastened to the housing 200, thus completing the installation of the high-voltage connector seat 100 and the housing 200.

[0029] Method 2: Place the first flange 1 inside the housing 200, move the first flange 1 towards the inner wall of the housing 200, move the other end of the conductive terminal 2 into the first through hole 2001 of the housing 200, so that one side of the first flange 1 abuts against the inner wall of the housing 200, then align the clearance hole 31 of the second flange 3 with the other end of the conductive terminal 2, and move the second flange 3 towards the housing 200, so that the other side of the second flange 3 abuts against the outer wall of the housing 200, then pass fasteners through the second through hole to connect the first flange 1 and the second flange 3, so that the first flange 1 and the second flange 3 are fastened to the housing 200, and then connect one end of the conductive terminal 2 to the high voltage busbar inside the battery pack 1000, thus completing the installation of the high voltage connector seat 100 and the housing 200.

[0030] The high-voltage connector base 100 of this utility model supports the conductive terminal 2 through the first flange 1 and the protective shell 4 through the second flange 3, thus separating the conductive terminal 2 and the protective shell 4. Therefore, when installing the conductive terminal 2, the influence of the protective shell 4 does not need to be considered, allowing the conductive terminal 2 to be installed on the housing 200 from the inside. This allows the connection step between the conductive terminal 2 and the high-voltage busbar to be performed before or after the high-voltage connector base 100 is fixed to the housing 200, thereby providing more possibilities for the fixing scheme of the high-voltage busbar and making the fixing scheme of the high-voltage busbar more flexible.

[0031] Therefore, the high-voltage connector base 100 of this utility model embodiment can realize two connection sequences of conductive terminal 2 and high-voltage busbar during the installation process of high-voltage connector base 100 and housing 200, providing a flexible high-voltage busbar fixing scheme.

[0032] Therefore, the fixing method of the high voltage busbar of the battery pack 1000 in this embodiment of the present invention is more flexible.

[0033] In some embodiments, such as Figures 2 to 4 As shown, the first flange 1 has threaded holes, and the second flange 3 has fixing holes. Both the threaded holes and fixing holes correspond to the second through hole of the housing 200. Fasteners are bolts, which are fitted into the fixing holes and threaded holes. When installing the bolts, the bolts are passed through the fixing holes and the second through hole in sequence, and then rotated to connect the bolts to the threaded holes. The fasteners, using bolts to connect the first flange 1, housing 200, and second flange 3, are simple to manufacture and install, making them easy to operate.

[0034] In some embodiments, the threaded holes include a plurality of first threaded holes 11 and second threaded holes 12, and the fixing holes include a plurality of first fixing holes 32 and second fixing holes 33. The plurality of first threaded holes 11 and the plurality of first fixing holes 32 correspond one-to-one, and the plurality of second threaded holes 12 and the plurality of second fixing holes 33 correspond one-to-one. The plurality of first threaded holes 11 are located at the edge of the first flange 1, and the plurality of second fixing holes 33 are adjacent to the protective shell 4. Correspondingly, the plurality of first fixing holes 32 are located at the edge of the second flange 3, and the plurality of second threaded holes 12 are adjacent to the protective shell 4. This forms a plurality of first fastening connection points at the edges of the first flange 1 and the second flange 3, and a plurality of second fastening connection points near the center of the first flange 1 and the second flange 3 near the protective shell 4. This increases the connection strength between the first flange 1, the second flange 3, and the housing 200, thereby increasing the strength of the high-voltage connector seat 100 and the connection strength between the high-voltage connector seat 100 and the housing 200 in this embodiment of the invention.

[0035] In some embodiments, the threaded hole is a blind hole, so the fastening bolt will not be exposed in the inner space of the housing 200, and nuts are not required inside the housing 200, reducing the number of parts, simplifying the installation process, improving the installation efficiency of the high-voltage connector seat 100, and increasing the protective performance of the housing 200, preventing dust, moisture and other impurities from the external environment of the housing 200 (battery pack 1000) from entering the inner side of the housing 200 through the threaded hole.

[0036] Specifically, the diameter of the second threaded hole 12 is smaller than the diameter of the first threaded hole 11, and correspondingly, the diameter of the second fixing hole 33 is smaller than the diameter of the first fixing hole 32, and the diameter of the fastening bolt installed in the second threaded hole 12 is smaller than the diameter of the fastening bolt installed in the first threaded hole 11.

[0037] In some embodiments, such as Figure 3 As shown, a first mounting groove is provided on one side of the first flange 1, which surrounds the conductive terminal 2. The high-voltage connector seat 100 further includes a sealing gasket 5, which is disposed in the first mounting groove to abut against the inner wall surface of the housing 200 and surround the first through hole 2001 and the second through hole. The sealing gasket 5 fits against the first flange 1 and the inner wall surface of the housing 200, thereby sealing the area between the first flange 1 and the inner wall surface of the housing 200. This prevents dust, moisture, and other impurities from the external environment of the housing 200 from entering the inside of the housing 200 through the first through hole 2001 and the second through hole, thus improving the protective performance of the housing 200, which in turn improves the protective performance of the battery pack 1000.

[0038] Specifically, the sealing gasket 5 has a first annular hole and a second annular hole. The first annular hole surrounds the conductive terminal 2 and is opposite to the first through hole 2001. The sealing gasket 5 forms a seal at the first through hole 2001. The second annular hole is opposite to the threaded hole to ensure that the opening of the threaded hole is open. The sealing gasket 5 forms a seal at the second through hole.

[0039] In some embodiments, such as Figure 4 As shown, the other side of the second flange 3 is provided with a second mounting groove, which surrounds the clearance hole 31. The high-voltage connector seat 100 further includes a sealing ring 6, which is disposed in the second mounting groove to abut against the housing 200 and surround the first through hole 2001. The second mounting groove surrounds the clearance hole 31, that is, the second mounting groove is an annular groove. The sealing ring 6 surrounds the first through hole 2001 and fits against the other side of the second flange 3 and the outer wall of the housing 200, thereby isolating the space between the other side of the second flange 3 and the outer wall of the housing 200 from the first through hole 2001. The first through hole 2001 is sealed on the outside of the housing 200, preventing dust, moisture and other impurities in the external environment of the housing 200 from entering the first through hole 2001 through the space between the other side of the second flange 3 and the outer wall of the housing 200, and thus entering the inside of the housing 200, further improving the protective performance of the housing 200 and the battery pack 1000.

[0040] In some embodiments, the first flange 1 and the conductive terminal 2 are an integral structure. Integrating the first flange 1 and the conductive terminal 2 into one unit eliminates the need to assemble the first flange 1 and the conductive terminal 2 separately when installing the high-voltage connector socket 100, thereby improving the installation efficiency of the high-voltage connector socket 100 while ensuring the connection strength and integrity of the first flange 1 and the conductive terminal 2.

[0041] Specifically, the first flange 1 is made of insulating material, which provides insulation protection for the conductive terminal 2.

[0042] Optionally, the gasket 5 is bonded to this side of the first flange 1, thereby making the first flange 1 and the gasket 5 an integral structure.

[0043] In some embodiments, the second flange 3 and the protective shell 4 are integrally formed, thereby eliminating the need to assemble the second flange 3 and the protective shell 4 when installing the high-voltage connector seat 100, thus improving the installation efficiency of the high-voltage connector seat 100, while also ensuring the connection strength and integrity of the second flange 3 and the protective shell 4, and eliminating the need for related connection structures.

[0044] Specifically, the second flange 3 and the protective shell 4 are made of metal die casting or plastic injection molding.

[0045] Optionally, the sealing ring 6 is bonded to the other side of the second flange 3, making the second flange 3 and the sealing ring 6 an integral structure.

[0046] Therefore, the high-voltage connector base 100 of this utility model embodiment is divided into three relatively independent parts. The first part consists of a first flange 1, a conductive terminal 2, and a sealing gasket 5, with the first flange 1 as the carrier; the second part consists of a second flange 3, a protective shell 4, and a sealing ring 6, with the second flange 3 as the carrier; and the third part consists of fasteners. This allows for reversing the installation sequence of the conductive terminal 2, the housing 200, and the high-voltage busbar, while also enabling convenient operation, high installation efficiency, and good sealing of the first through hole 2001 and the second through hole of the housing 200, thereby improving the protective performance of the housing 200 and the battery pack 1000.

[0047] The high-voltage connector assembly of this utility model is described below according to an embodiment.

[0048] The high-voltage connector assembly of this utility model embodiment includes a high-voltage connector base 100 and a high-voltage connector plug, which is simultaneously connected to the other end of the conductive terminal 2 and the protective shell 4.

[0049] The high-voltage connector assembly of this utility model embodiment has a relatively flexible installation method, which can realize two connection sequences between the conductive terminal 2 and the high-voltage busbar, and provides a flexible high-voltage busbar fixing scheme.

[0050] The vehicle according to an embodiment of the present invention is described below.

[0051] The vehicle in this embodiment of the utility model includes a battery pack 1000.

[0052] Therefore, the vehicle of this utility model embodiment has good flexibility in the arrangement of high-voltage busbars.
