Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, and in particular to a terminal body, a terminal, a connector, a battery pack and a vehicle. Background Art

[0002] As people's awareness of automobile safety increases, the terminals at the battery pack end are required to have their own waterproof devices and the terminal waterproof ring structure of the high-voltage connector.

[0003] In the related technology, there are two main types of waterproofing on existing terminals. One is that the waterproof ring is directly assembled in the terminal slot, which requires a certain degree of precision in the processing of the terminal slot to ensure the accuracy of assembly. The degree of automation is low, and the sealing ring is easily scratched during manual assembly, resulting in a high defect rate. The other is that the terminal and the sealing ring are directly injection molded as one piece. After injection molding, the plastic peeling force is insufficient, and there will be a gap between the sealing ring and the terminal, resulting in problems of falling off and sealing failure. In addition, there is another method of applying glue to a specific area of ​​the terminal, and then injection molding it with a specific plastic or directly injection molding it to achieve a waterproof effect. This method applies glue to a specific area of ​​the terminal. During the operation, the amount of glue and the area cannot be controlled. After the injection molding is completed, the glue liquid will penetrate into other parts of the terminal, resulting in poor appearance. Secondly, glue leakage will occur in mass production. This process has low production efficiency and relatively high labor costs. Utility Model Content

[0043] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0044] Reference below Figure 1-Figure 7 The terminal body 1 according to the embodiment of the utility model can make the adhesion between the seal 201 and the fixing part 13 stronger, thereby solving the problem of insufficient peeling force between the seal 201 and the terminal 100 after conventional overmolding, and can also reduce the production process, thereby improving the degree of automation of product manufacturing.

[0045] Combination Figure 1-Figure 7 As shown, the terminal body 1 according to the embodiment of the first aspect of the utility model includes a first connection end 11, a second connection end 12 and a fixing portion 13. Among them, the first connection end 11 and the second connection end 12 can respectively serve as connection carriers for electrically connecting the terminal body 1 to related components; the fixing portion 13 can provide waterproof protection for the terminal 100, that is, to prevent water from flowing into the interior of the terminal 100 and causing the risk of short circuit. For example, the seal 201 can be a waterproof ring made of plastic material, so that it is easy to process the seal 201 of the desired shape through the injection molding process; the terminal body 1 can be made of copper, so that the conduction efficiency of the electrical connection can be improved.

[0046] Specifically, the fixing portion 13 is connected between the first connection end 11 and the second connection end 12 , and a protrusion 131 is formed on the fixing portion 13 . The fixing portion 13 is used to fix the sealing member 201 , and the protrusion 131 is used to match the sealing member 201 in a concave-convex manner.

[0047] In detail, the first connection terminal 11 and the second connection terminal 12 can be electrically connected to different components respectively, so as to achieve the effect of transmitting electrical energy or electrical signals between different components; and the fixed part 13 is connected between the first connection terminal 11 and the second connection terminal 12, so that it is convenient to block the seal 201 matched with the fixed part 13 between the first connection terminal 11 and the second connection terminal 12, thereby preventing water from flowing along the terminal body 1 from one end of the first connection terminal 11 and the second connection terminal 12 to the other end of the first connection terminal 11 and the second connection terminal 12, thereby ensuring the circuit safety of related components.

[0048] Furthermore, the protrusion 131 on the fixing portion 13 and the seal 201 are matched along the circumferential concave-convex structure, which can increase the contact area between the terminal body 1 and the seal 201, thereby making the connection adhesion between the seal 201 and the fixing portion 13 on the terminal 100 stronger, thereby solving the problem of insufficient peeling force between the seal 201 and the terminal body 1 after conventional overmolding; the continuous concave-convex structure can also enhance the limiting effect of each other, thereby enhancing the anti-slip effect of the seal 201, and thereby improving the position stability between the two.

[0049] In addition, compared to the seal directly assembled in the terminal slot (which requires a certain degree of precision in the terminal slot processing to ensure the accuracy of assembly, has a low degree of automation, and the seal is easily scratched during manual assembly, resulting in a high defect rate), in the embodiment of the present case, the seal 201 and the terminal body 1 can be directly injection molded as one piece (for example, a protrusion 131 is squeezed out of the fixing portion 13 in a specific area of ​​the terminal 100 through a stamping process, and then injection molded. During the molding process, the seal 201 made of plastic material will be tightly wrapped around the protrusion 131 and integrated), thereby reducing production processes, reducing defect rates, improving manufacturing efficiency, and thus saving costs.

[0050] Moreover, compared to the direct integral molding of the terminal and the seal by injection molding (the seal peeling force of the plastic material after injection molding is insufficient, there will be a gap between the seal and the terminal, and there will be problems of falling off and sealing failure), the embodiment in this case, due to the concave-convex fit between the seal 201 and the protrusion 131, can increase the connection contact area and limiting effect between the seal 201 and the terminal 100, thereby increasing the adhesion between the seal 201 and the fixed part 13, and then increasing the position stability between the seal 201 and the fixed part 13.

[0051] In addition, compared to applying glue to a specific area of ​​the terminal and then injection molding it with a specific plastic to achieve a waterproof effect (this method applies glue to a specific area of ​​the terminal, and during the operation, the amount of glue and the area cannot be controlled. After the injection molding is completed, the glue liquid will penetrate into other parts of the terminal, resulting in poor appearance; secondly, glue leakage will occur during mass production. This process has low production efficiency and high labor costs), the embodiment of the present case can directly extrude the protrusion 131 of the fixing part 13 through a stamping process in the specific area of ​​the terminal body 1 (that is, the fixing part 13), and then directly injection mold it with the seal 201. During the molding process, the seal 201 made of plastic material will be tightly wrapped around the protrusion 131 and integrated, thereby improving production efficiency and reducing labor costs.

[0052] Therefore, by setting the terminal body 1, the adhesion between the seal 201 and the fixing part 13 can be made stronger, thereby solving the problem of insufficient peeling force between the seal 201 and the terminal 100 after conventional plastic packaging. It can also reduce production processes, reduce manufacturing defective rate, and improve work efficiency, thereby improving the degree of automation of product manufacturing and saving costs.

[0053] According to some optional embodiments of the present invention, combined with Figure 4 and Figure 5 As shown, the cross-sectional area of ​​the protrusion 131 perpendicular to the thickness direction of the first connection end 11 (that is, the cross-sectional area of ​​the protrusion 131) is reduced in the direction away from the fixing portion 13. Among them, the cross-sectional area of ​​the protrusion 131 perpendicular to the thickness direction of the first connection end 11 gradually increases in the direction close to the fixing portion 13, so that in the process of assembling the seal 201 on the fixing portion 13 (such as the injection molding process), the contact area between the seal 201 and the fixing portion 13 can be made larger and larger in the direction close to the fixing portion 13, thereby increasing the adhesion between the seal 201 and the fixing portion 13 near the root of the fixing portion 13, avoiding the risk of the seal 201 falling off the fixing portion 13 due to insufficient peeling force; it can also play a pre-guiding role for the seal 201 to be assembled on the protrusion 131 of the fixing portion 13, thereby improving the assembly efficiency.

[0054] Specifically, combined Figure 4 and Figure 5 As shown, the protrusion 131 is constructed as an arc-shaped protrusion 131. Such an arrangement allows the adhesion force to be more evenly dispersed on the seal 201 during the process of assembling the seal 201 on the fixing portion 13 (such as an injection molding process), thereby improving the force uniformity of the overall structure of the seal 201, avoiding the risk of damage to the seal 201 due to stress concentration, and thus extending the service life of the seal 201.

[0055] Optionally, combined Figure 4As shown, the protrusion 131 is connected to the first connection end 11. Such an arrangement can make the protrusion 131 closer to the first connection end 11, so that the protrusion 131 can be easily matched according to the external dimensions of the first connection end 11 and the component connected thereto, thereby improving the rationality of the spatial arrangement.

[0056] Alternatively, the protrusion 131 is connected to the second connection end 12. Such an arrangement can make the protrusion 131 closer to the second connection end 12, thereby facilitating position matching according to the external dimensions of the second connection end 12 and the component connected thereto, thereby improving the rationality of the spatial arrangement.

[0057] According to some optional embodiments of the present invention, combined with Figure 4 and Figure 5 As shown, there are multiple protrusions 131, and the multiple protrusions 131 are arranged at intervals along the width direction of the terminal body 1, and a recessed space is formed between two adjacent protrusions 131. Among them, multiple protrusions 131 can be arranged at intervals on the fixing part 13 in the width direction of the terminal body 1, and multiple protrusions 131 can increase the number of protrusions 131, thereby increasing the mutual contact area and limiting position between the fixing part 13 and the sealing member 201, thereby enhancing the adhesion of the sealing member 201 on the fixing part 13, and improving the position stability between the sealing member 201 and the fixing part 13.

[0058] In addition, multiple protrusions 131 are arranged at intervals on the fixing portion 13, so that a recessed structure can be defined between adjacent protrusions 131, thereby increasing the limiting effect of the terminal body 1 on the seal 201 through continuous protrusions 131 and recessed structures, thereby further enhancing the position stability between the seal 201 and the fixing portion 13.

[0059] Specifically, combined Figure 4 and Figure 5 As shown, in the width direction of the terminal body 1, a plurality of protrusions 131 are arranged at equal intervals along the width direction of the terminal body 1. It can be understood that along the width direction of the terminal body 1, a plurality of protrusions 131 are arranged at equal intervals. Such an arrangement can make the force between the seal 201 and the fixing portion 13 along the width direction of the terminal body 1 more uniform, avoid excessive or insufficient force on one side in the width direction, thereby improving the uniformity of the force of the seal 201 on the fixing portion 13; and can also make the arrangement of the protrusions 131 more regular, which is conducive to simplifying the processing technology and improving the processing efficiency.

[0060] Furthermore, combined with Figure 4 and Figure 5As shown, the dimensions of the plurality of protrusions 131 along the thickness direction of the first connecting end 11 are the same. Such an arrangement can unify the dimensions of the protrusions 131 extending into the seal 201, making the spatial arrangement of the plurality of protrusions 131 more regular, thereby ensuring the force consistency between the seal 201 and the fixing portion 13 along the height direction of the protrusions 131, and can also simplify the processing technology, ensure processing consistency, and improve processing efficiency.

[0061] According to some optional embodiments of the present invention, combined with Figure 3 and Figure 5 As shown, the fixing portion 13 is provided with a limiting portion 132 on at least one side in the width direction of the terminal body 1, and the limiting portion 132 is used to limit the seal 201. Among them, along the width direction of the terminal body 1, the limiting portion 132 is provided on the fixing portion 13, and the limiting portion 132 can be in a limiting cooperation relationship with the seal 201, so that the sealing member 201 can be limited, thereby avoiding the risk of the sealing member 201 easily falling off from the fixing portion 13, thereby improving the position stability between the two.

[0062] Specifically, combined Figure 1 and Figure 7 As shown, the limiting portion 132 is constructed as a limiting groove. With such an arrangement, the concave structure of the limiting groove and the partial structure on the seal 201 can be used to match the shape, so that on the one hand, the limiting portion 132 can have a limiting effect on the seal 201, and on the other hand, the contact and adhesion area between the seal 201 and the limiting portion 132 can be increased, thereby improving the adhesion between the seal 201 and the terminal body 1.

[0063] According to some optional embodiments of the present invention, combined with Figure 1 and Figure 4 As shown, the first connection end 11 is formed with a connection hole 111, and the connection hole 111 is used to connect with the conductive member through the connector. Among them, the connection hole 111 on the first connection end 11 can establish a stable connection relationship with the conductive member through the connector, thereby ensuring the stable transmission of the electrical signal between the terminal body 1 and the copper busbar. In addition, the connector can also play the role of installing and fixing the terminal body 1 and the copper busbar, thereby taking into account the stability of the electrical signal transmission and the assembly stability between the two. For example, the conductive member can be a copper busbar of a battery pack.

[0064] According to some optional embodiments of the present invention, combined with Figure 1 , Figure 3 and Figure 4 As shown, the second connection end 12 includes a mounting portion 121 and an elastic clamping portion 122 . The mounting portion 121 is connected to the fixing portion 13 , and the elastic clamping portion 122 is connected to the mounting portion 121 . The elastic clamping portion 122 is bent relative to the mounting portion 121 .

[0065] Furthermore, in the direction from the second connection end 12 to the first connection end 11, the elastic clamping portion 122, the mounting portion 121 and the fixing portion 13 are connected in sequence. The elastic clamping portion 122 can be elastically deformed to generate elastic force, so that the elastic deformation ability can be used to flexibly match the connection ports on components of different sizes, thereby increasing the connection versatility of the terminal body 1; the elastic deformation ability can also be used to flexibly perform plugging and unplugging actions with the connection ports on the relevant components under the action of external force interference according to the needs of the user to achieve the effect of whether it is electrically connected, thereby improving its convenience of assembly and disassembly.

[0066] In addition, the two ends of the mounting portion 121 are respectively connected to the elastic clamping portion 122 and the fixing portion 13, so that on the basis of providing mounting and fixing conditions for the second connection end 12, it can also extend the size of the second connection end 12 and serve as a transition carrier between the elastic clamping portion 122 and the fixing portion 13, thereby improving the rationality of its layout.

[0067] Moreover, the elastic clamping portion 122 is connected to the mounting portion 121 in a bent manner, so that the original extension direction of the mounting portion 121 can be changed, so that the elastic clamping portion 122 is constructed in an arch shape, thereby forming a path that can be decomposed into extensions along the length direction and the height direction. On the one hand, this can reduce the force required to overcome the deformation of the elastic clamping portion 122, and on the other hand, it can also form an elastic restoring force in the height direction, avoiding the risk of the elastic clamping portion 122 failing elastically and being unable to clamp, thereby improving the service life and working stability of the elastic clamping portion 122.

[0068] Furthermore, combined with Figure 3 and Figure 4 As shown, the elastic clamping portion 122 includes a first bending segment 1222 and a second bending segment 1223. The first bending segment 1222 is connected to the mounting portion 121 and is bent relative to the mounting portion 121. In a direction away from the mounting portion 121, the distance from the first bending segment 1222 to a side surface of the mounting portion 121 along the thickness direction of the mounting portion 121 increases gradually. The second bending segment 1223 is connected to the first bending segment 1222 and is bent relative to the first bending segment 1222. In a direction away from the first bending segment 1222, the distance from the second bending segment 1223 to a side surface of the mounting portion 121 along the thickness direction of the mounting portion 121 decreases gradually.

[0069] It can be understood that the first bending section 1222 is bent and connected to the mounting portion 121, so that the original extension direction of the mounting portion 121 can be changed, and the second bending section 1223 is bent and connected to the first bending section 1222, so that the original extension direction of the first bending section 1222 can be changed again, and the first bending section 1222 and the second bending section 1223 can be constructed in a similar arch-shaped structure, so that it is convenient to form a clamping space for the structure connected to the terminal body 1 (that is, when the relevant structure needs to overcome a large elastic force to achieve the effect of entering the clamping space, similarly, when the relevant structure needs to leave the clamping space, it also needs to overcome a large elastic force), thereby improving the connection reliability between the terminal body 1 and the relevant structure; and such an arrangement allows the elastic clamping portion 122 to decompose the component forces along the thickness direction and length direction of the terminal body 1, thereby enhancing the elastic reset effect of the elastic clamping portion 122 along the thickness direction of the terminal body 1, thereby improving the durability of the elastic clamping portion 122.

[0070] Specifically, combined Figure 3 , Figure 4 and Figure 6 As shown, the second bending section 1223 includes a plurality of elastic clamping arms 1221 , which are arranged at intervals along the width direction of the terminal body 1 , and one end of each elastic clamping arm 1221 is connected to the first bending section 1222 .

[0071] It can be understood that, along the width direction of the terminal body 1, multiple elastic clamping arms 1221 are arranged at intervals, so that multiple relatively independent contact positions of components connected to the elastic clamping portion 122 can be formed, thereby avoiding the connection failure problem caused by the uneven contact position between the connection port on the component and the elastic clamping portion 122. That is, the multiple elastic clamping arms 1221 in the present case can independently and adaptively elastically deform the surface of the connection port on the connected component to establish a contact relationship, thereby ensuring the stable transmission effect of the electrical signal.

[0072] Among them, one end (that is, the fixed end) of each elastic clamping arm 1221 is connected to the mounting portion 121, so that an installation support effect can be provided to the elastic clamping portion 122; the other end of each elastic clamping arm 1221 is suspended (that is, the free end), so that the other end of the elastic clamping arm 1221 can flexibly and adaptively deform elastically according to the size of the matching component connection port to establish a connection relationship.

[0073] Combination Figure 3 and Figure 4As shown, the terminal 100 according to the embodiment of the second aspect of the utility model includes the terminal body 1 of the above-mentioned embodiment. The terminal 100 having the terminal body 1 can make the adhesion between the seal 201 and the fixing part 13 stronger, thereby solving the problem of insufficient peeling force between the seal 201 and the terminal 100 after conventional plastic wrapping, and can also reduce the production process, reduce the manufacturing defect rate, and improve work efficiency, thereby improving the degree of automation of product manufacturing and saving costs.

[0074] Specifically, combined Figure 2 , Figure 3 and Figure 6 As shown, there are multiple terminal bodies 1, and the multiple terminal bodies 1 include a first terminal body 14 and a second terminal body 15 that are stacked, the second connection end 12 of the first terminal body 14 and the second connection end 12 of the first terminal body 15 together form a terminal connecting portion 16, and the protrusion 131 of the first terminal body 14 and the protrusion 131 of the first terminal body 15 protrude in a direction away from each other.

[0075] It is understandable that the first terminal body 14 and the first terminal body 15 are stacked correspondingly, so that the weight and spatial mode of each other can be increased, thereby improving the structural strength and bending and torsional rigidity of the two. Among them, the second connection end 12 of the first terminal body 14 and the second connection end 12 of the first terminal body 15 jointly define a terminal connection portion 16, that is, the first terminal body 14 and the first terminal body 15 are formed with a terminal connection portion 16 with a tendency to interlock with each other on both sides in the height direction (that is, the stacking direction of the first terminal body 14 and the second terminal body 15), so that the connection port of the relevant components can be connected in the terminal connection portion 16, thereby ensuring the stability of the transmission of electrical signals.

[0076] Furthermore, combined with Figure 1-Figure 3 and Figure 6 As shown, the terminal 100 further includes a fixing component 2 , which is disposed at the second connection end 12 of the first terminal body 14 and the second connection end 12 of the first terminal body 15 .

[0077] That is to say, the fixing components 2 are respectively arranged on the outside of the second connecting end 12 of the first terminal body 14 and the outside of the second connecting end 12 of the first terminal body 15, so that the installation and fixing and structural reinforcement effects of the first terminal body 14 and the first terminal body 15 can be further enhanced, and the risk of the installation part 121 being loosened or deformed due to excessive force on the elastic clamping part 122 is avoided, thereby improving the structural reliability and installation stability at the second connecting end 12 of the first terminal body 14 and the second connecting end 12 of the first terminal body 15.

[0078] Specifically, combined Figure 1-Figure 3 and Figure 6As shown, the fixing assembly 2 includes a first fixing member 21, a second fixing member 22 and a fastener 23. The first fixing member 21 is arranged on the side of the second connecting end 12 of the first terminal body 14 away from the first terminal body 15, and the first fixing member 21 is arranged on the side of the second connecting end 12 of the first terminal body 15 away from the first terminal body 14. The fastener 23 is respectively connected to the first terminal body 14, the first terminal body 15, the first fixing member 21 and the second fixing member 22.

[0079] It can be understood that, as arranged above, the fastener 23 can be sequentially passed through the first fixing member 21, the first terminal body 14, the first terminal body 15 and the second fixing member 22 to tightly connect them as a whole, thereby increasing the weight and spatial mode of each other, and further enhancing the overall structural strength and bending and torsional stiffness of the terminal 100.

[0080] Furthermore, combined with Figure 1 , Figure 3 and Figure 6 As shown, the second connection end 12 includes a mounting portion 121 and an elastic clamping portion 122 . The mounting portion 121 is connected to the fixing portion 13 , and the elastic clamping portion 122 is connected to the mounting portion 121 . The elastic clamping portion 122 is bent relative to the mounting portion 121 .

[0081] It can be understood that the elastic clamping portion 122, the mounting portion 121 and the fixing portion 13 are connected in sequence along the direction from the second connection end 12 to the first connection end 11. The elastic clamping portion 122 can be elastically deformed to generate elastic force, so that the elastic deformation ability can be used to flexibly match the connection ports on components of different sizes, thereby increasing the connection versatility of the terminal body 1; the elastic deformation ability can also be used to flexibly perform plugging and unplugging actions with the connection ports on the relevant components under the action of external force interference according to the needs of the user to achieve the effect of whether it is electrically connected, thereby improving its convenience of disassembly and assembly.

[0082] In addition, the two ends of the mounting portion 121 are respectively connected to the elastic clamping portion 122 and the fixing portion 13, so that on the basis of providing mounting and fixing conditions for the second connection end 12, it can also extend the size of the second connection end 12 and serve as a transition carrier between the elastic clamping portion 122 and the fixing portion 13, thereby improving the rationality of its layout.

[0083] Moreover, the elastic clamping portion 122 is connected to the mounting portion 121 in a bent manner, so that the original extension direction of the mounting portion 121 can be changed, so that the elastic clamping portion 122 is constructed in an arch shape, thereby forming a path that can be decomposed into extensions along the length direction and the height direction. On the one hand, this can reduce the force required to overcome the deformation of the elastic clamping portion 122, and on the other hand, it can also form an elastic restoring force in the height direction, avoiding the risk of the elastic clamping portion 122 failing elastically and being unable to clamp, thereby improving the service life and working stability of the elastic clamping portion 122.

[0084] Furthermore, combined with Figure 2 , Figure 3 and Figure 6 As shown, the first fixing member 21 and the second fixing member 22 both include a fixing plate 24 and an elastic limiting plate 25. The fixing plate 24 corresponds to the mounting portion 121, and the fixing plate 24 and the mounting portion 121 are connected via a fastener 23. The elastic limiting plate 25 is connected to the fixing plate 24, and the elastic limiting plate 25 corresponds to the elastic clamping portion 122 to limit the degree of elastic deformation of the elastic clamping portion 122.

[0085] Among them, the fixing plates 24 on the first fixing member 21 and the second fixing member 22 correspond to the mounting portion 121 on the terminal body 1, and the elastic limiting plates 25 on the first fixing member 21 and the second fixing member 22 correspond to the elastic clamping portion 122 on the terminal body 1. In this way, the first fixing member 21 and the second fixing member 22 can better fit the outer surface contour of the terminal body 1, thereby enhancing the structural strength of the mounting portion 121 on the terminal body 1 and the clamping force of the elastic clamping portion 122, thereby improving the overall structural reliability and clamping stability of the terminal 100.

[0086] Specifically, combined Figure 3 and Figure 4 As shown, the elastic clamping portion 122 includes a first bending segment 1222 and a second bending segment 1223. The first bending segment 1222 is connected to the mounting portion 121 and is bent relative to the mounting portion 121. In a direction away from the mounting portion 121, the distance from the first bending segment 1222 to a side surface of the mounting portion 121 along the thickness direction of the mounting portion 121 increases gradually. The second bending segment 1223 is connected to the first bending segment 1222 and is bent relative to the first bending segment 1222. In a direction away from the first bending segment 1222, the distance from the second bending segment 1223 to a side surface of the mounting portion 121 along the thickness direction of the mounting portion 121 decreases gradually.

[0087] It can be understood that the first bending section 1222 is bent and connected to the mounting portion 121, so that the original extension direction of the mounting portion 121 can be changed, and the second bending section 1223 is bent and connected to the first bending section 1222, so that the original extension direction of the first bending section 1222 can be changed again, and the first bending section 1222 and the second bending section 1223 can be constructed in a similar arch-shaped structure, so that it is convenient to form a clamping space for the structure connected to the terminal body 1 (that is, when the relevant structure needs to overcome a large elastic force to achieve the effect of entering the clamping space, similarly, when the relevant structure needs to leave the clamping space, it also needs to overcome a large elastic force), thereby improving the connection reliability between the terminal body 1 and the relevant structure; and such an arrangement allows the elastic clamping portion 122 to decompose the component forces along the thickness direction and length direction of the terminal body 1, thereby enhancing the elastic reset effect of the elastic clamping portion 122 along the thickness direction of the terminal body 1, thereby improving the durability of the elastic clamping portion 122.

[0088] Furthermore, combined with Figure 3 and Figure 4 As shown, the elastic limiting plate 25 includes a first bending plate 251 and a second bending plate 252. The first bending plate 251 is connected to the fixed plate 24 and is bent relative to the fixed plate 24. In the direction away from the fixed plate 24, the distance from the first bending plate 251 to a side surface of the fixed plate 24 along the thickness direction of the fixed plate 24 increases. The first bending plate 251 corresponds to the first bending section 1222 to limit the elastic deformation degree of the first bending section 1222. The second bending plate 252 is connected to the first bending plate 251 and is bent relative to the first bending plate 251. In the direction away from the first bending plate 251, the distance from the second bending plate 252 to a side surface of the fixed plate 24 along the thickness direction of the fixed plate 24 decreases. The second bending plate 252 corresponds to the second bending section 1223 to limit the elastic deformation degree of the second bending section 1223.

[0089] That is to say, the first bending plate 251 is bent and connected to the fixed plate 24, so that the original extension direction of the fixed plate 24 can be changed, and the second bending plate 252 is bent and connected to the first bending plate 251, so that the original extension direction of the first bending plate 251 can be changed again, and the first bending plate 251 and the second bending plate 252 can be constructed into an arch-like structure, so that the outer contour of the first bending section 1222 and the second bending section 1223 that are attached to the elastic clamping portion 122 can be better matched, thereby strengthening the structural strength of the first bending section 1222 and the second bending section 1223, thereby improving the service life and connection reliability.

[0090] Furthermore, combined with Figure 1 and Figure 3As shown, the first bent plate 251 is formed with a through hole 2511, and the first bent plate 251 is provided with a stress release plate 2512 on one side of the through hole 2511, and the stress release plate 2512 is formed by bending a portion of the plate body of the first bent plate 251 corresponding to the through hole 2511. Among them, the middle part of the first bent plate 251 can be formed with a through hole 2511. Since the structural strength of the middle part of the first bent plate 251 is greater, the opening of the through hole is conducive to releasing or reducing the force applied to the middle part of the first bent plate 251, thereby preventing the first bent plate 251 from being damaged, deformed, or even failing. In addition, the stress release plate 2512 is formed by bending a portion of the plate body of the first bent plate 251 corresponding to the through hole 2511, which is convenient for processing and manufacturing and simplifies the process.

[0091] According to some optional embodiments of the utility model, the first terminal body 1 and the second terminal body 15 are integrally formed, and the first connection end 11 of the first terminal body 14 is bent relative to the second connection end 12 of the second terminal body 15. Among them, the first terminal body 14 and the second terminal body 15 can be formed in an integral manner, which can increase the overall consistency and structural stability of the first terminal body 14 and the second terminal body 15 compared to the split assembly, thereby improving their working reliability. In addition, the first connection end 11 of the first terminal body 14 is bent relative to the second connection end 12 of the second terminal body 15, so that it is convenient to define a clamping space between the second connection end 12 of the first terminal body 14 and the second connection end 12 of the second terminal body 15, thereby ensuring that the terminal 100 can exert a clamping force on the relevant mechanism to achieve a stable connection effect.

[0092] Combination Figure 1 and Figure 7 As shown, the connector 200 according to the third embodiment of the utility model includes the terminal 100 and the sealing member 201 of the above embodiment, the sealing member 201 is arranged on the fixing portion 13, and the sealing member 201 is formed with a groove 2011, and the groove 2011 is matched with the protrusion 131. In other words, the groove 2011 on the sealing member 201 and the protrusion 131 at the fixing portion 13 on the terminal 100 are matched with each other in a concave-convex manner, so that on the one hand, the contact area between the sealing member 201 and the fixing portion 13 can be increased, and on the other hand, the concave-convex matching structure can also limit each other, thereby increasing the adhesion between the two, and then solving the problem of insufficient peeling force between the sealing member 201 and the terminal 100 after conventional overmolding.

[0093] According to some optional embodiments of the present invention, combined with Figure 4 and Figure 5 As shown, there are a plurality of protrusions 131 , which are spaced apart along the width direction of the terminal body 1 , and there are a plurality of grooves, which are matched with the plurality of protrusions 131 in a one-to-one corresponding manner.

[0094] Specifically, a plurality of protrusions 131 can be arranged at intervals on the fixing portion 13 in the width direction of the terminal body 1, and a plurality of protrusions 131 can increase the number of protrusions 131, thereby increasing the mutual contact area and limiting position between the fixing portion 13 and the seal 201, thereby enhancing the adhesion of the seal 201 on the fixing portion 13, and improving the position stability between the seal 201 and the fixing portion 13. In addition, a plurality of protrusions 131 are arranged at intervals on the fixing portion 13, so that a concave structure can be defined between adjacent protrusions 131, thereby increasing the limiting effect of the terminal body 1 on the seal 201 through continuous protrusions 131 and concave structures, thereby further enhancing the position stability between the seal 201 and the fixing portion 13.

[0095] According to some optional embodiments of the present invention, combined with Figure 1 , Figure 4 , Figure 5 and Figure 7 As shown, the sealing member 201 and the fixing portion 13 are injection molded. Injection molding can be performed by injecting molten thermoplastic plastic into a mold, and when the plastic is cooled and solidified, a product of a desired shape is formed. When the sealing member 201 and the fixing portion 13 are injection molded, the sealing member 201 can be tightly molded around the outer periphery of the fixing portion 13, thereby improving the waterproofness of the terminal 100.

[0096] The battery pack according to the fourth embodiment of the utility model includes the connector 200 of the above embodiment. The battery pack with the connector 200 can improve the adhesion of the seal 201, reduce the production process, improve the degree of automation of product manufacturing, and save costs.

[0097] The vehicle according to the fifth embodiment of the utility model includes the battery pack of the above embodiment. The vehicle having the battery pack can improve the waterproof reliability and safety of the battery pack, thereby improving the market competitiveness.
