[0026] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-7 The connector housing 100 according to an embodiment of the present utility model is described.

[0027] The connector housing 100 according to a first aspect embodiment of the present invention is characterized in that it comprises: The main body 1 has a first mounting hole 11, which is adapted for the connecting strip 5 to pass through and be fixed to the main body 1. In some embodiments, the main body 1 and the connecting strip 5 are separate structures. After the main body 1 is manufactured, it is fixed to the main body 1 by the connecting strip 5 passing through the first mounting hole 11. In some embodiments, the specific fixing method can be an interference fit, that is, the Y-direction cross-sectional dimension of the connecting strip 5 is larger than the Y-direction cross-sectional dimension of the first mounting hole 11; in some embodiments, it can also be fixed by separate fasteners. For example, it can be fixed by opening through holes in the main body 1 and the connecting strip 5 respectively, passing fastening screws through the through holes, and locking them with nuts on the other side.

[0028] A first groove 12 is formed on one end face of the main body 1. The first groove 12 can completely penetrate the main body 1 or partially penetrate it. The first groove 12 and the first mounting hole 11 are separated by an isolation part 2. The housing part shared by the first groove 12 and the first mounting hole 11 is constructed as the isolation part 2. A notch 13 is formed on the isolation part 2. The notch 13 can completely penetrate the isolation part 2 or partially penetrate it. The notch 13 connects the first mounting hole 11 and the first groove 12. It is suitable to fill the first groove 12 with colloid. After the colloid solidifies, it fills the gap between the first groove 12, the notch 13, and the main body 1 and the connecting row 5, thereby achieving a seal between the main body 1 and the connecting row 5.

[0029] In some embodiments, the notch 13 can be composed of multiple notch 13 sub-units, such as multiple notch 13 sub-units evenly or non-evenly distributed on the isolation portion 2, as long as the opening of the notch 13 sub-units can achieve communication between the first groove 12 and the first mounting hole 11. A seal between the body portion 1 and the connecting row 5 can be achieved by injecting colloid into the first mounting groove.

[0030] In some embodiments, the shape of the notch 13 subunit can be regular (circle, triangle, etc.) or irregular, as long as it can connect the first groove 12 and the first mounting hole 11, the technical solution and the technical effect are the same as those in this application.

[0031] In some embodiments, after the connecting strip 5 and the battery pack housing 81 are connected together via the body part 1, insulation is required between the connecting strip 5 and the battery pack housing 81 to prevent electrical connection between them and potential safety hazards. Therefore, the body part 1 needs to be made of an insulating material. For example, when the body part 1 is injection molded, its material can be common plastic injection molding materials such as ABS or PP. Ceramic materials can also be used as needed to achieve better insulation and heat dissipation.

[0032] In some embodiments, the first mounting hole 11 extends from one end face of the body portion 1 to the other end face. After the connecting strip 5 passes through the first mounting hole 11, both ends of the connecting strip 5 are outside the body portion 1, that is, a portion of the structure at each end of the connecting strip 5 is not inside the first mounting hole 11. One end of the connecting strip 5 is adapted to connect to the main positive / main negative output terminal (i.e., the output interface of the main positive or main negative terminal of the battery pack 8) inside the battery pack 8, and the other end of the connecting strip 5 is adapted to connect to an external device. In some embodiments, the external device can be a vehicle charging port.

[0033] In some embodiments, the connecting busbar 5 can be a copper busbar, an aluminum busbar, or a copper-aluminum composite busbar welded together with one end made of copper and the other end made of aluminum.

[0034] In some embodiments, there are multiple first grooves 12, which are disposed on both sides of the first mounting hole 11, and are separated from the first mounting hole 11 by multiple isolation portions 2.

[0035] In some embodiments, such as Figure 1 As shown, there are four first grooves 12. Two of the four first grooves 12 are located on one side of the first mounting hole 11, and the other two are located on the other side of the first mounting hole 11. Each of the four grooves has an isolation portion 2 between it and the first mounting hole 11, and the isolation portion 2 achieves isolation between the first groove 12 and the first mounting hole 11.

[0036] In some embodiments, a notch 13 is provided on a plurality of isolation portions 2, and the plurality of notches 13 connect the first mounting hole 11 and the plurality of first grooves 12.

[0037] The purpose is to achieve communication between the first mounting hole 11 and the plurality of first grooves 12 through the notch 13. Furthermore, by filling the plurality of first grooves 12 with adhesive, a seal is achieved between the body part 1 and the connecting row 5.

[0038] More specifically, the colloid needs to fill multiple first grooves 12 and multiple notches 13. After the colloid cures, it can fill the multiple first grooves 12, multiple notches 13, and the assembly gap between the connecting row 5 and the first mounting hole 11 to achieve a seal between the body part 1 and the connecting row 5.

[0039] like Figure 6 As shown, in some embodiments, the connector housing further includes a flange 3, which surrounds the body 1. The connector housing is adapted to mate the assembly points on the flange 3 with the assembly points on the battery pack housing 81 using a first fastener 9 for installation.

[0040] In some embodiments, the flange portion 3 and the body portion 1 can be separate structures or an integral structure. When they are separate structures, the outer surface of the body portion 1 is provided with external threads, and the flange portion 3 has a mounting hole with internal threads on its inner wall. The internal threads of the flange portion 3 are screwed together with the external threads of the body portion 1 to achieve assembly and fixation between the flange portion 3 and the body portion 1. When they are an integral mechanism, they can be formed by processes such as injection molding, die casting, and machining, which will not be described in detail here.

[0041] like Figure 2 As shown, in some embodiments, the flange portion 3 divides the body portion 1 into a first body portion 14 and a second body portion 15, and the connector housing is adapted to be installed with the battery pack 8 via the second body portion 15.

[0042] In some embodiments, the flange portion 3 is disposed in the middle region of the body portion 1, dividing the body portion 1 into two parts. One part is the first body portion 14, which faces the outside of the battery pack housing 81. The other part is the second body portion 15, which mates with the third mounting hole 811 opened on the battery pack housing 81 to fix the connector housing to the battery pack 8.

[0043] In summary, the connector housing first assembles the second body part 15 into the third mounting hole 811 to achieve the initial assembly between the connector housing and the battery pack housing 81. Then, the first fastener 9 connects and fastens the assembly points on the flange surface to the assembly points on the battery pack housing 81 to achieve the installation and fixation between the connector housing and the battery pack housing 81.

[0044] In some embodiments, a first annular groove 16 is provided on the second body portion 15. The cross-sectional shape of the first annular groove 16 along the Y direction can be rectangular, semi-circular, etc. At least one first annular groove 16 is provided surrounding the second body portion 15, and correspondingly, at least one first sealing member 6 is also provided. The first annular groove 16 is adapted to install the first sealing member 6. When the outer peripheral surface of the second body portion 15 mates with the inner wall of the third mounting hole 811 of the battery pack housing 81, a seal is achieved between the two by compressing the first sealing member 6.

[0045] In some embodiments, the cross-sectional shape of the first annular groove 16 along the Y direction can be rectangular, semi-circular, etc.

[0046] In some embodiments, a second annular groove 31 is provided on the flange portion 3, the second annular groove 31 is disposed around the second body portion 15, and the second annular groove 31 is adapted to accommodate the second sealing member 7. The cross-sectional shape of the second annular groove 31 along the Y direction can be rectangular, semi-circular, etc. At least one second annular groove 31 is provided, and correspondingly, at least one second sealing member 7 is also provided. When the flange portion 3 is engaged with the fourth groove 813 of the battery pack housing 81, the mating surface between the flange portion 3 and the battery pack housing 81 is sealed by compressing the second sealing member 7.

[0047] In some embodiments, the first sealing element 6 is a circular sealing ring, and the second sealing element 7 is a rectangular sealing ring. The two sealing elements work together to effectively ensure the sealing effect of the contact area between the battery pack housing 81 and the connector housing.

[0048] In some embodiments, a second boss 33 is provided in the second annular groove 31. At least one second boss 33 is provided along the side wall of the second annular groove 31. Its function is that when the second sealing member 7 is accommodated in the second annular groove 31, the second boss 33 is used to squeeze the second sealing strip to fix the second sealing member 7, so as to ensure that the second sealing strip will not fall out when it is installed in the second annular groove 31.

[0049] In some embodiments, when the number of second protrusions 33 is set to multiple, multiple protrusions can be spaced apart on opposite sidewalls of the second annular groove 31, or multiple protrusions can be spaced apart on only one sidewall. Both arrangements can achieve the fixation of the second sealing strip.

[0050] In some embodiments, the flange 3 is further provided with at least one second mounting hole 32, and the connector housing is adapted to engage with the internal thread of the fourth mounting hole 812 of the battery pack housing 81 through the second mounting hole 32 via a first fastener 9, thereby realizing the installation between the flange 3 and the battery pack housing 81. That is, the second mounting hole 32 is a through hole, and the fourth mounting hole 812 is a threaded hole.

[0051] In some embodiments, when there is only one second mounting hole 32 on the flange 3, a locating pin needs to be provided on the flange 3 simultaneously, and installation is achieved by the cooperation of the locating pin and the second mounting hole 32. When there are multiple second mounting holes 32 on the flange 3, it is optional to provide a locating pin, depending on the actual application.

[0052] In some embodiments, a reinforcing part 4 is provided between the first body part 14 and the flange part 3. The reinforcing part 4 is connected between the first body part 14 and the flange part 3 to strengthen the structural strength between the flange part 3 and the body part 1, and to prevent the connector housing from being damaged when dropped or impacted.

[0053] In some embodiments, the number of reinforcing parts 4 can be one or more, which can be determined according to the space arrangement requirements and the usage parameters of the connector housing.

[0054] like Figure 3 As shown, the connector 200 according to a second aspect embodiment of the present invention includes a connecting strip 5 and the connector housing 100 described above. The connecting strip 5 and the connector housing can each be an independent component, which are fixed together by assembly. Alternatively, they can be integrally formed.

[0055] In some embodiments, the connector strip 5 and the connector housing can be integrally molded using an injection molding process, which is similar to a plastic coating process. Specifically, the plastic connector housing is wrapped around the metal connector strip 5 in a mold, and after the plastic cures, the two are integrally formed as a single unit. The advantages of integral molding of the connector strip 5 and the connector housing are that it saves steps during actual assembly, improves production efficiency, reduces the number of parts, and lowers management costs.

[0056] like Figure 2 As shown, in some embodiments, a first boss 17 is provided on the inner wall of the first mounting hole 11 of the connector housing, and a third groove 51 is provided at the corresponding mating position of the connecting row 5. After the connector housing and the connecting row 5 are integrally formed, the first boss 17 and the third groove 51 are mated.

[0057] In some embodiments, when the connecting strip 5 and the connector housing are integrally formed by injection molding, at least one third groove 51 may be provided on the connecting strip 5. During the injection molding process, after the liquid plastic material in the mold cavity is filled and solidified, it wraps around the connecting strip 5, while the third groove 51 is filled with solid plastic material (the solid plastic material in the third groove 51 is constructed as a first boss 17). In this way, after the connecting strip 5 and the connector housing are integrally formed, the mating and limiting relationship between the third groove 51 and the connector housing prevents the connecting strip 5 from coming off the connector housing during use.

[0058] In some embodiments, in order to facilitate installation of the connection bar 5 with terminals inside the battery pack 8 and external devices, at least part of the connection bar 5 is flexible in structure.

[0059] In some embodiments, the connecting strip 5 is composed of layers of thin copper foil stacked together. The mounting areas at both ends of the connecting strip 5 are firmly welded using polymer diffusion welding, facilitating bolt installation. The non-welded areas are soft and flexible, allowing for tolerance absorption during assembly and improving assembly capability. This makes it easier for the connecting strip 5 to be installed with terminals inside the battery pack 8 and external devices. Furthermore, the connecting strip 5 can be designed as a straight or bent structure as needed.

[0060] like Figure 3 As shown, in some embodiments, one end of the connecting strip 5 is provided with a first through hole 52, and the connecting strip 5 is adapted to be connected to the terminals in the battery pack 8 through the first through hole 52; the other end of the connecting strip 5 is provided with a second through hole 53, and the connecting strip 5 is adapted to be connected to an external device through the second through hole 53.

[0061] In some embodiments, such as Figure 4 As shown, the connecting strip 5 is composed of layers of thin copper foil stacked together. The first through hole 52 and the second through hole 53 are located in the welding mounting areas at both ends of the connecting strip 5. Because this area is fixed by welding, it is rigid. The first through hole 52 and the second through hole 53 are located in this area, which, compared to a flexible area, facilitates connection with the terminals of the battery pack 8 and external devices. The first through hole 52 and the second through hole 53 can be punched with either a slotted hole or a round hole as needed to absorb assembly tolerances and improve assembly capability.

[0062] In some embodiments, such as Figure 5 As shown, a press-fit nut 54 can be added at the first through hole 52 and / or the second through hole 53 to facilitate bolt installation.

[0063] The vehicle according to a third aspect of the present invention includes a battery pack 8, the connector housing described above, or the connector described above.

[0064] In some embodiments, by injecting colloid into the first groove 12 on the body portion 1, the colloid fills the gap between the first groove 12, the notch 13, and the connecting strip 5 and the first mounting hole 11. This not only secures the body portion 1 and the connecting strip 5 together, but also achieves a seal between them. When the connecting strip 5 and the body portion 1 are integrally formed, the connecting strip 5 is first fixed to the connector by injection molding, and then colloid is injected into the first groove 12, filling the first groove 12 and the notch 13. This not only further secures the body portion 1 and the connecting strip 5 together, but also further achieves a seal between them. This prevents external air, liquid, foreign objects, etc., from entering the battery pack housing 81 and causing corrosion or short circuits inside the battery pack housing 81.
