[0088] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative labor are within the protection scope of the present application.

[0089] Referring to Figures 1 to 4 As a first aspect of the present application, the present application provides a connection terminal 100.

[0090] Referring to Figure 1 The connection terminal 100 mainly includes a first connection portion 110, a second connection portion 120 and a torsion portion 130.

[0091] The first connection portion 110 is formed with a first connection surface 111; the second connection portion 120 is formed with a second connection surface 121. The first connection surface 111 and the second connection surface 121 are both used to form electrical connection by contact. When the first connection surface 111 and the second connection surface 121 respectively form contact with different first and second components, the connection terminal 100 forms a current path between the first and second components through its electrical conductivity, thereby forming electrical connection between the first and second components.

[0092] That is, the first connection portion 110 provides the first connection surface 111 for connecting the first component; the second connection portion 120 provides the second connection surface 121 for connecting the second component.

[0093] The first connecting part 110 is generally connected by single-sided contact, i.e. only has one first connecting surface 111; in some application scenarios, the first connecting part 110 can also have two oppositely arranged or adjacently arranged first connecting surfaces 111. When oppositely arranged, the two first connecting surfaces 111 can be arranged in parallel; when adjacently arranged, the two first connecting surfaces 111 can be arranged perpendicularly to each other.

[0094] Similarly, the second connecting part 120 is generally connected by single-sided contact, i.e. only has one second connecting surface 121; in some application scenarios, the second connecting part 120 can also have two oppositely arranged or adjacently arranged second connecting surfaces 121. When oppositely arranged, the two second connecting surfaces 121 can be arranged in parallel; when adjacently arranged, the two second connecting surfaces 121 can be arranged perpendicularly to each other.

[0095] The torsion part 130 is arranged between the first connecting part 110 and the second connecting part 120, and mainly serves to connect, and the torsion part 130 is not used for contact conduction. The main role of the torsion part 130 is to relatively deflect the first connecting surface 111 and the second connecting surface 121 by a certain angle through its own shape, when there are multiple first connecting surfaces 111 and second connecting surfaces 121, a corresponding group of first connecting surfaces 111 and second connecting surfaces 121 can be relatively deflected by a certain angle; or all the first connecting surfaces 111 and the second connecting surfaces 121 do not coincide, so that any two first connecting surfaces 111 and second connecting surfaces 121 are relatively deflected by a certain angle.

[0096] That is, the torsion part 130 is connected between the first connecting part 110 and the second connecting part 120 and forms a preset included angle between the first connecting surface 111 and the second connecting surface 121.

[0097] Referring to FIG. 1, Figure 3 The first connecting surface 111 and the second connecting surface 121 can be planes, and a preset included angle a is formed between the first connecting surface 111 and the second connecting surface 121 at this time. As an optional solution, the first connecting surface 111 and the second connecting surface 121 can also be curved surfaces, which can be a single curved surface or a composite curved surface composed of multiple single curved surfaces.

[0098] If the first connecting surface 111 and the second connecting surface 121 are the same curved surface, the included angle formed by the tangent plane corresponding to a reference point of them is taken as the preset included angle defined in the present application; if the first connecting surface 111 and the second connecting surface 121 are different curved surfaces, the maximum one of multiple included angles formed by all tangent planes of them is taken as the preset included angle defined in the present application.

[0099] Referring to FIG. 1, Figure 4 The first connecting part 110 and the second connecting part 120 can be arranged in parallel. Figure 4 The angle between the extension direction in the preset plane represented by the paper plane (horizontal plane perpendicular to the front-rear direction) is also defined as the preset angle of the present application. As an example, in the specific embodiment shown in Figures 1 to 3 In the specific embodiment provided, in the preset plane constituted by the up-down direction and the left-right direction, the second connecting part 120 forms a preset angle with the first connecting part 110 through the torsion part 130.

[0100] The extension direction of the first connecting part 110 in the preset plane refers to the maximum dimension direction D1 of the projection outline of the first connecting part 110 in the preset plane. Similarly, the extension direction of the second connecting part 120 in the preset plane refers to the maximum dimension direction D2 of the projection outline of the second connecting part 120 in the preset plane.

[0101] When the torsion angle is measured as the angle of the extension direction in the preset plane, the volume properties of the first connecting part 110 and the second connecting part 120 can be better reflected, so that the flexible connection of the first connecting part 110 and the second connecting part 120 can be better achieved through the setting of the preset angle.

[0102] With the above scheme, compared with the common one-piece stamping terminal stamping process, the present application forms a torsion part 130 between the first connecting part 110 and the second connecting part 120, so that the first connecting part 110 and the second connecting part 120 can form a more flexible connection than the conventional one-piece stamping terminal through the torsion part 130. In the case of forming a preset angle between the first connecting surface 111 and the second connecting surface 121, when the end position of the first connecting part 110 or the second connecting part 120 is locked to the external conductive part such as copper bar, the first connecting part 110 and the second connecting part 120 can be relatively twisted, thereby reducing the strong stress of the locking position of the connecting terminal 100, making the electrical connection end surface of the connecting terminal 100 more closely combined, thereby ensuring the effectiveness of the contact and reducing the connection stress. And in the use scene where the assembly space is limited, this configuration can reduce the space size of the reserved space around the connecting terminal 100 for ensuring the assembly precision, thereby being applicable to more use scenes.

[0103] In some embodiments, in the arrangement direction of the first connecting part 110, the torsion part 130 and the second connecting part 120, the length of the first connecting part 110 is greater than the length of the second connecting part 120. As an example, referring to Figure 2 As shown, in the specific embodiment shown in Figure 2 In the specific embodiment shown, the front-rear direction is the arrangement direction of the first connecting part 110, the torsion part 130 and the second connecting part 120.

[0104] The different lengths of the first connecting portion 110 and the second connecting portion 120 can be adapted to connect different components. For example, the first connecting portion 110 can be connected to a conductive component such as an external copper bar, and the second connecting portion 120 can be connected to a hard solid busbar.

[0105] In the related art, the hard solid busbar is often combined with the connecting terminal 100 by welding or other combination methods before the copper bar is assembled to the connecting terminal 100, and then the corresponding connecting structure on the connecting terminal 100 is used to fix the copper bar and the connecting terminal 100. By making the length of the first connecting portion 110 greater than the length of the second connecting portion 120, the first type of connecting terminal 100 with a larger size can be used to configure the assembly structure connected to the copper bar.

[0106] That is, by using the above scheme, the use scenarios in which the first connecting portion 110 and the second connecting portion 120 are respectively connected to external structures of different structures can be adapted, the physical size of the connecting terminal 100 can be fully utilized, the assembly work can be facilitated, and the connection stability can be improved.

[0107] In some embodiments, in the arrangement direction of the first connecting portion 110, the torsion portion 130, and the second connecting portion 120, the length of the torsion portion 130 is greater than the length of the second connecting portion 120, so that the torsion portion 130 has a considerable length, thereby enabling the connecting terminal 100 to have sufficient deformation ability when assembled to components such as copper bars, thereby improving the connection stability.

[0108] In some embodiments, the length of the torsion portion 130 ranges from 15 mm to 35 mm, and more specifically, the length of the torsion portion 130 ranges from 20 mm to 30 mm. In a limited space, reasonable design of the length of the torsion portion 130 is beneficial to improve its stress bearing capacity, and at the same time, the size of the torsion portion 130 is not too large, so that the connecting terminal 100 is relatively easy to deform under external force, thereby causing the connecting terminal 100 to be unstable in connection with the copper bar, the hard solid busbar, and the like.

[0109] When the relative length and size changes among the first connecting portion 110, the second connecting portion 120, and the torsion portion 130 are considered, the stability of the connection between the connecting terminal 100, the busbar, the copper bar, and the like, and the structural strength of the connecting terminal 100 itself will have a great influence, and therefore the size of the first connecting portion 110, the second connecting portion 120, and the torsion portion 130 can be controlled to ensure that the connecting terminal 100 meets the use requirements.

[0110] For example, in the arrangement direction of the first connecting portion 110, the torsion portion 130, and the second connecting portion 120, the ratio of the length of the first connecting portion 110 to the length of the second connecting portion 120 ranges from 1.5 to 3.5. More specifically, for example, the ratio of the length of the first connecting portion 110 to the length of the second connecting portion 120 can be 2.5. This ensures that the first connecting portion 110 has sufficient length to connect to conductive components such as a copper busbar, while not being too long to easily bend when subjected to pressure.

[0111] For another example, in the arrangement direction of the first connecting portion 110, the torsional portion 130, and the second connecting portion 120, the ratio of the length of the first connecting portion 110 to the length of the torsional portion 130 ranges from 1.2 to 3.2. More specifically, for example, the ratio of the length of the first connecting portion 110 to the length of the torsional portion 130 can be 2.2. This ensures that the torsional portion 130 has deformability while the connecting terminal 100 itself has sufficient rigidity to prevent excessive deformation of the connecting terminal 100 when subjected to external forces.

[0112] For another example, in a direction perpendicular to the arrangement direction of the first connecting portion 110, the torsion portion 130, and the second connecting portion 120, the ratio of the width of the first connecting portion 110 to the width of the second connecting portion 120 ranges from 0.5 to 1.5. More specifically, for example, the ratio of the width of the first connecting portion 110 to the width of the second connecting portion 120 can be set to 1 to avoid the problem of a large difference in width between the first connecting portion 110 and the second connecting portion 120 causing material waste on the larger of the two and insufficient connection strength on the smaller of the two.

[0113] As an example, see Figure 2 and Figure 3 As shown, in Figure 2 and Figure 3 In the illustrated embodiment, the left-right direction is a direction perpendicular to the arrangement direction of the first connecting portion 110 , the torsion portion 130 , and the second connecting portion 120 .

[0114] For another example, in a direction perpendicular to the arrangement direction of the first connecting portion 110, the torsional portion 130, and the second connecting portion 120, the ratio of the width of the first connecting portion 110 to the width of the torsional portion 130 ranges from 0.5 to 1.5. More specifically, for example, the ratio of the width of the first connecting portion 110 to the width of the torsional portion 130 can be 1, thereby avoiding material waste or insufficient connection strength caused by a large difference in the width of the first connecting portion 110 and the torsional portion 130.

[0115] In some embodiments, the first connection surface 111 and the second connection surface 121 are both configured as planes, that is, compared to the mating surface forming a curved surface, the first connection part 110 or the second connection part 120 and the connected copper busbar, hard solid busbar, etc. can more easily form surface contact, while meeting the connection strength while having lower requirements for assembly accuracy, thereby facilitating assembly.

[0116] In some embodiments, reference Figure 1 As shown, the first connecting portion 110 is provided with a connecting hole 112 , which can be used as the aforementioned connecting structure for connecting to a conductive component such as a copper busbar by means of threaded connection, pin fixation, etc.

[0117] In some embodiments, reference Figure 1 As shown, the first connecting portion 110 is provided with a fixing hole 113. The connecting hole 112 and the mounting hole 451 are positioned at different locations relative to the arrangement of the first connecting portion 110, the torsion portion 130, and the second connecting portion 120. In a specific embodiment, considering requirements for insulation or electromagnetic shielding of the connecting terminal 100 from the outside world, the connecting terminal 100 can be assembled to a connector 10 using threaded connections, pin fixation, or other methods at the fixing hole 113. This connector 10 can then be used to provide insulation or electromagnetic shielding for the connecting terminal 100, thereby meeting practical requirements.

[0118] In some embodiments, reference Figure 2 As shown, the aperture of the connection hole 112 is larger than the aperture of the fixing hole 113. By limiting the aperture of the connection hole 112, it is ensured that the size of the components such as the pins and screws configured at the connection hole 112 for connecting the copper busbar and the first connection part 110 meets the requirements, thereby ensuring the connection strength between the copper busbar and other conductive components and the first connection part 110.

[0119] In some embodiments, reference Figure 2 As shown, the fixing hole 113 is arranged between the connecting hole 112 and the torsion portion 130. This configuration allows at least a portion of the first connecting portion 110 to be conveniently arranged outside the connector 10 after the connecting terminal 100 is installed using the connector 10, while the second connecting portion 120 and the torsion portion 130 can be conveniently arranged inside the connector 10. While using the connector 10 to achieve functions such as insulation or electromagnetic shielding, it is convenient to assemble the first connecting portion 110 with conductive components such as copper busbars.

[0120] In some embodiments, considering that the torsion portion 130 is more prone to deformation during use than the first connection portion 110 and the second connection portion 120, the torsion portion 130 can be covered with an insulating layer 320. The insulating layer 320 can be made of PVC material, etc., and corresponding flame retardants can be added to enhance safety performance during use.

[0121] In some embodiments, the connection terminal 100 is made of a metal material containing copper, which has excellent electrical conductivity and can ensure the electrical conductivity of the connection terminal 100.

[0122] In some embodiments, referring to Figure 1 As shown, the torsion portion 130 is stacked by multiple metal layers 101, and in some examples, the metal layers 101 are made of copper-containing material, and the metal layers 101 can further be provided with a plating layer such as a Sn layer to improve the corrosion resistance of the metal layers 101. It should be noted that in some embodiments, the connection terminal 100 can be formed after the multiple metal layers are stacked and a hard contact layer is closed outside the first connection portion 110 and the second connection portion 120; in other embodiments, only the torsion portion 130 can be stacked by multiple metal layers, and the first connection portion 110 and the second connection portion 120 can be hard copper bars, and the first connection portion 110 and the second connection portion 120 are connected to the torsion portion 130 by welding to form the connection terminal 100.

[0123] For each metal layer 101, its thickness can be selected according to the corresponding design requirements. In some embodiments of the present application, the thickness of a single metal layer 101 can be between 0.2 mm and 0.3 mm. In a more specific solution, the thickness of a single metal layer 101 can be between 0.23 mm and 0.27 mm, so that the single layer thickness has the function of softening and absorbing the installation stress caused by rigid connection.

[0124] For the connection terminal 100 stacked by multiple metal layers 101, the number of stacked metal layers 101 can be controlled to be between 15 pcs and 17 pcs, and the two sides of the whole stacked by the metal layers 101 are segmented by welding process, so that the thickness of the torsion portion 130 is between 20 mm and 30 mm, which can twist a certain angle while adapting to the design space of the corresponding connector 10.

[0125] In some embodiments, the preset angle of the torsion between the first connection portion 110 and the second connection portion 120 is in the range of 1° to 20°, and more specifically, the preset angle is in the range of 1° to 15°. In a specific hard solid core conductive busbar connection solution, when the hard solid core conductive busbar and copper bar are connected using the above-mentioned connection terminal 100, the problem of incomplete joint of the electrical connection surface caused by stress relaxation of the rigid hard solid core conductive busbar in the connected state can be avoided.

[0126] According to the second aspect of the present application, referring to Figures 5 to 21As shown, the present application provides a connector 10 comprising the aforementioned connecting terminal 100, when the connecting terminal 100 is used to connect the conductive parts such as copper bars and bus bars, the connector 10 has all the beneficial effects of the aforementioned connecting terminal 100, which will not be repeated here.

[0127] In some embodiments, referring to Figure 6 and Figure 7 As shown, the connector 10 further comprises a first housing 200. The first housing 200 is used to cover at least a part of the connecting terminal 100, so as to realize the insulation or electromagnetic shielding function of at least a part of the connecting terminal 100 by using the first housing 200. The first housing 200 further comprises a first limiting portion, which is in limiting cooperation with the first connecting surface 111 of the connecting terminal.

[0128] The first housing 200 is composed of, for example, a flexible insulating material, and more specifically, it can be made of plastic material, so as to be used for isolating the connecting terminal 100 from other components in terms of electrical conduction, and to provide assembly guide and limiting functions for the connecting terminal 100.

[0129] Referring to Figure 5 and Figure 7 As shown in Figure 5 and Figure 7 In the specific scheme of the examples, in order to match the shape and structure of the connecting terminal 100, the wire outlet hole in the first housing 200 for mounting the connecting terminal 100 and exposing the first connecting portion 110 is arranged to have a certain angle in the left-right direction as shown in Figure 5 so that the first connector 10 can occupy a smaller width in the left-right direction as shown in Figure 5 and it is easy to install the connecting terminal 100 in a narrow space.

[0130] In some embodiments, referring to Figure 5 and Figure 6 As shown, the connector 10 further comprises a connecting cable 300 and a second housing 400.

[0131] The connecting cable 300 is connected to the second connecting portion 120, and the connecting cable 300 can be used as the aforementioned bus bar, and is combined with the connecting terminal 100, for example, by welding or the like, and more specifically, ultrasonic welding or the like can be used to realize the fixed connection of the connecting cable 300 and the second connecting portion 120. The present application does not make specific limitation on the outer diameter of the connecting cable 300 as a hard solid core bus bar, for example, the outer diameter of the connecting cable 300 can be φ16mm-φ28mm.

[0132] The second housing 400 is used to cover at least a portion of the connecting cable 300, thereby providing protection for at least a portion of the connecting cable 300. The first housing 200 and the second housing 400 are fixedly connected so that the second housing 400 at least partially covers the outside of the first housing 200. The first housing 200 and the second housing 400 overlap in space, facilitating the configuration of a corresponding structure to connect the first housing 200 and the second housing 400, thereby maintaining a stable relative position between the connecting cable 300 and the connecting terminal 100, thereby providing stable protection for the connecting cable 300 and the connecting terminal 100.

[0133] In a specific embodiment, the second housing 400 includes a second body 410, which has a second accommodating cavity 411 formed therein. One end of the connecting cable 300 is inserted into the second accommodating cavity 411, and the second accommodating cavity 411 communicates with the first accommodating cavity 202. This allows at least a portion of the connecting cable 300 and at least a portion of the connecting terminal 100 to be disposed in the space formed by the first accommodating cavity 202 and the second accommodating cavity 411. Thus, the first housing 200 and the second housing 400 provide protection for the portion where the connecting cable 300 and the connecting terminal 100 are joined.

[0134] In some embodiments, reference Figure 8 , Figure 14 , Figure 15 and Figure 16 As shown, the connecting cable 300 includes a core 310 and an insulating layer 320.
