The first electrical connector is electrically connected to the second electrical connector.

[0006] In the technical solution of the present application, the connecting component includes a first electrical connector and a second electrical connector. A part of the second electrical connector can be arranged in a first connecting hole on the first electrical connector. Since the first connecting hole is used to at least limit the movement of the second electrical connector along the radial direction of the first connecting hole, the first connecting hole and the second connecting hole can be aligned with each other, and the second electrical connector can be preliminarily positioned on the first electrical connector in a preset posture (when the second electrical connector is in a preset posture, the central axis of the first connecting hole and the central axis of the second connecting hole coincide with each other), so as to facilitate the use of the first connecting hole and the second connecting hole that are aligned with each other to make the first electrical connector and the second electrical connector more stably electrically connected.

Figure 3 A partial cross-sectional schematic diagram of a connector assembly in an embodiment of the present application is shown. Figure 4 Shows Figure 3 An enlarged schematic diagram of point A.

[0050] Please refer to Figure 2-Figure 4An embodiment of the present application provides a connector assembly, including a first connector 100 , the first connector 100 includes a connection assembly, and the connection assembly includes a first electrical connector 110 and a second electrical connector 120 .

[0051] The first electrical connector 110 and the second electrical connector 120 are both electrically conductive components. For example, the first electrical connector 110 is a copper busbar or an aluminum busbar, and the second electrical connector 120 is a metal bushing.

[0052] The first electrical connector 110 is provided with a first connection hole K1 , and a portion of the second electrical connector 120 is disposed in the first connection hole K1 , wherein the second electrical connector 120 is provided with a second connection hole K2 that communicates with the first connection hole K1 .

[0053] The first connection hole K1 is used to at least limit the movement of the second electrical connector 120 along the radial direction of the first connection hole K1 so that the central axis of the first connection hole K1 can coincide with the central axis of the second connection hole K2, and the first electrical connector 110 is electrically connected to the second electrical connector 120.

[0054] The first connection hole K1 refers to a hole provided on the first electrical connector 110 and communicating with the second connection hole K2 . The first connection hole K1 may be provided through the first electrical connector 110 along the thickness direction of the first electrical connector 110 .

[0055] The first connection hole K1 can be a round hole or a square hole.

[0056] The second connection hole K2 refers to a hole provided on the second electrical connector 120 and communicating with the first connection hole K1 . The second connection hole K2 may be provided through the second electrical connector 120 along the thickness direction of the second electrical connector 120 .

[0057] The second connecting hole K2 can be a round hole or a square hole.

[0058] In the technical solution of the present application, a part of the second electrical connector 120 can be arranged in the first connecting hole K1 on the first electrical connector 110. Since the first connecting hole K1 is used to at least limit the movement of the second electrical connector 120 along the radial direction of the first connecting hole K1, the first connecting hole K1 and the second connecting hole K2 can be aligned with each other, and the second electrical connector 120 can also be preliminarily positioned on the first electrical connector 110 in a preset posture (when the second electrical connector 120 is in a preset posture, the central axis of the first connecting hole K1 and the central axis of the second connecting hole K2 coincide with each other), so as to facilitate the use of the first connecting hole K1 and the second connecting hole K2 that are aligned with each other to make the first electrical connector 110 and the second electrical connector 120 more stably electrically connected.

[0059] The first electrical connector 110 and the second electrical connector 120 may be electrically connected by welding; or a conductive component may be inserted through the first connection hole K1 and the second connection hole K2 to electrically connect the first electrical connector 110 and the second electrical connector 120; or the first electrical connector 110 and the second electrical connector 120 may be electrically connected by welding or by a conductive component may be inserted through the first connection hole K1 and the second connection hole K2 to electrically connect the first electrical connector 110 and the second electrical connector 120. No specific limitation is made here.

[0060] In some embodiments, the first connection hole K1 is used to limit the movement of the second electrical connector 120 along the radial direction of the first connection hole K1 and to limit the movement of the second electrical connector 120 along the axial direction of the first connection hole K1 toward the side close to the first electrical connector 110 .

[0061] After the first electrical connector 110 is fixed, the first connecting hole K1 is used to limit the movement of the second electrical connector 120 along the axial direction of the first connecting hole K1 toward the side close to the first electrical connector 110. In this way, the first electrical connector 110 can be used to well limit the movement of the second electrical connector 120, and the second electrical connector 120 can be initially positioned on the first electrical connector 110 in a preset posture, so that the first electrical connector 110 and the second electrical connector 120 can be more stably electrically connected by using the first connecting hole K1 and the second connecting hole K2 that are aligned with each other.

[0062] In some embodiments, please refer to Figure 4-Figure 6 The first connecting hole K1 includes a first hole segment K11 and a second hole segment K12 that are connected. The second electrical connector 120 includes a first portion 121 and a second portion 122 that are connected. The first portion 121 is disposed in the first hole segment K11, and the second portion 122 is located outside the first connecting hole K1. In addition, along the axial direction of the first connecting hole K1, the second portion 122 is located on a side of the first hole segment K11 away from the second hole segment K12. The aperture of the first hole segment K11 is larger than the aperture of the second hole segment K12.

[0063] The first hole section K11 refers to a hole section with a larger hole diameter on the first connecting hole K1.

[0064] The second hole section K12 refers to a hole section with a smaller hole diameter on the first connecting hole K1.

[0065] The first portion 121 refers to the portion of the second electrical connector 120 that is disposed in the first hole section K11 .

[0066] The second portion 122 refers to a portion of the second electrical connector 120 located outside the first connection hole K1 .

[0067] Since the aperture of the first hole segment K11 is larger than the aperture of the second hole segment K12, a portion of the first electrical connector 110 abuts against the second electrical connector 120 along the direction from the second hole segment K12 to the first hole segment K11, and the first electrical connector 110 can be used to limit the movement of the second electrical connector 120 along the axial direction of the first connection hole K1 toward the side close to the first electrical connector 110; and another portion of the first electrical connector 110 is arranged around the second electrical connector 120 to limit the movement of the second electrical connector 120 along the radial direction of the first connection hole K1, so that the second electrical connector 120 can be well positioned on the first electrical connector 110 in a preset posture, so that the first electrical connector 110 and the second electrical connector 120 can be more stably electrically connected by using the first connection hole K1 and the second connection hole K2 that are aligned with each other.

[0068] In some embodiments, the first electrical connector 110 has a limiting surface 111 , which is perpendicular to the axial direction of the first connection hole K1 and is used to limit the movement of the second electrical connector 120 along the axial direction of the first connection hole K1 toward the side close to the first electrical connector 110 .

[0069] In some embodiments, the first portion 121 is disposed in the first hole segment K11 by interference fit.

[0070] If it is necessary to electrically connect the first electrical connector 110 and the second electrical connector 120 together by welding, since the second electrical connector 120 may be displaced due to slight vibration of the welding head during welding, it is necessary to arrange the first portion 121 in the first hole segment K11 with an interference fit. In this way, the first portion 121 of the second electrical connector 120 can be more firmly positioned in the first hole segment K11, which can reduce the influence of slight vibration of the welding head on the second electrical connector 120, thereby facilitating a more stable electrical connection between the first electrical connector 110 and the second electrical connector 120.

[0071] In some embodiments, the hole wall of the first hole segment K11 is adapted to the shape of the first portion 121 .

[0072] In this way, the first part 121 can be adaptively engaged with the hole wall of the first hole segment K11, so that the second electrical connector 120 can be initially positioned on the first electrical connector 110 when the central axis of the first connecting hole K1 and the central axis of the second connecting hole K2 coincide with each other, and the first electrical connector 110 and the second electrical connector 120 can be more stably electrically connected by utilizing the first connecting hole K1 and the second connecting hole K2 that are aligned with each other.

[0073] In some embodiments, the outer peripheral wall of the second electrical connector 120 is adapted to the hole wall of the first hole section K11 .

[0074] The second electrical connector 120 is configured as a column structure. For example, the second electrical connector 120 is configured as a cylindrical structure.

[0075] The second electrical connector 120 may be constructed as a column structure with the same outer diameter, which facilitates positioning of the second electrical connector 120 on the first electrical connector 110 and also facilitates designing and manufacturing the first electrical connector 110 and the second electrical connector 120 .

[0076] It should be supplemented that the first electrical connector 110 and the second electrical connector 120 of the present application are designed independently, and the first electrical connector 110 and the second electrical connector 120 can be manufactured according to their respective design requirements, which is helpful to reduce the design and manufacturing costs to a certain extent.

[0077] In some embodiments, the diameter of the second hole segment K12 is equal to the diameter of the second connecting hole K2.

[0078] It is convenient to pass a conductive component through the second hole section K12 and the second connecting hole K2 to electrically connect the first electrical connector 110 and the second electrical connector 120 .

[0079] In some embodiments, a cross section of the first connection hole K1 in a direction perpendicular to the axis of the first connection hole K1 is substantially circular.

[0080] In some embodiments, along the axial direction of the first connecting hole K1 , the length of the first hole segment K11 is smaller than the length of the second hole segment K12 .

[0081] The first hole section K11 of the first connection hole K1 can be used to at least limit the movement of the second electrical connector 120 along the radial direction of the first connection hole K1, and the strength requirement of the first electrical connector 110 can be met. In some embodiments, the connector assembly further includes a second connector 200 and a fourth electrical connector (not shown in the figure), the second connector 200 includes a third electrical connector 210, and the third electrical connector 210 is provided with a third connection hole K3 corresponding to the second connection hole K2. The fourth electrical connector is provided through the first connection hole K1, the second connection hole K2 and the third connection hole K3 to electrically connect the first electrical connector 110, the second electrical connector 120 and the third electrical connector 210.

[0082] The third electrical connection member 210 may be a component capable of conducting electricity. For example, the third electrical connection member 210 is a conductive column.

[0083] The third connection hole K3 refers to a hole provided on the third electrical connection member 210 and corresponding to the first connection hole K1 and the second connection hole K2 respectively.

[0084] The fourth connection member may be a component that is conductive and is respectively inserted into the first connection hole K1, the second connection hole K2, and the third connection hole K3. For example, the first connection hole K1, the second connection hole K2, and the third connection hole K3 are all pin holes, and the fourth connection member is a metal pin shaft that matches the pin hole; for another example, the first connection hole K1, the second connection hole K2, and the third connection hole K3 are all threaded holes, and the fourth connection member is a metal bolt that matches the bolt hole.

[0085] In this way, the first electrical connector 110, the second electrical connector 120 and the third electrical connector 210 can be electrically connected together using the fourth electrical connector. For example, the first connector 100 is a connector at the vehicle end, and the second connector 200 is a connector at the battery end. In this way, the battery cells of the battery device 10 can be electrically connected to the electrical components of the vehicle 1 by means of the first connector 100 and the second connector 200 to supply power to the electrical components.

[0086] In some embodiments, the first connector 100 further includes a first housing 130, the first housing 130 has a first accommodating cavity Q1, and the connecting assembly is disposed in the first accommodating cavity Q1. The second electrical connector 120 includes a first portion 121 and a second portion 122 connected to each other, the first portion 121 is disposed in the first connecting hole K1, and the second portion 122 is located outside the first connecting hole K1. A portion of the third electrical connector 210 is located in the first accommodating cavity Q1 and is in electrical contact with the second portion 122 of the second electrical connector 120.

[0087] The first housing 130 refers to a component of the first connector 100 for accommodating a connection component.

[0088] The first accommodating cavity Q1 refers to a cavity provided on the first shell 130 and used for accommodating the connecting component.

[0089] A portion of the third electrical connector 210 can be extended into the first shell 130 and located in the first accommodating cavity Q1, and electrically contacted with the second portion 122 of the second electrical connector 120. Therefore, the reliability of the electrical connection between the second electrical connector 120 and the third electrical connector 210 can be improved, and the first shell 130 can also be used to protect the connection components.

[0090] In some embodiments, the second connector 200 further includes a second housing 220, the second housing 220 having a second accommodating cavity Q2 for accommodating the third electrical connector 210, and the second accommodating cavity Q2 is in communication with the first accommodating cavity Q1. The second housing 220 and a portion of the third electrical connector 210 are both located in the first accommodating cavity Q1, and the second portion 122 of the second electrical connector 120 is located in the second accommodating cavity Q2 and is in electrical contact with the third electrical connector 210.

[0091] The second housing 220 refers to a component on the second connector 200 for accommodating the third electrical connector 210 .

[0092] The second accommodation cavity Q2 refers to a cavity provided on the second shell 220 for accommodating the third electrical connector 210 .

[0093] A portion of the third electrical connector 210 is inserted into the first accommodating cavity Q1, and the second portion 122 of the second electrical connector 120 is inserted into the second accommodating cavity Q2 and electrically contacted with the third electrical connector 210. Therefore, the connection reliability between the third electrical connector 210 and the second portion 122 can be improved, and the first shell 130 and the second shell 220 can be used to protect the third electrical connector 210, and the first shell 130 can also be used to protect the connection component.

[0094] In some embodiments, the first housing 130 is detachably connected to the second housing 220 .

[0095] In this way, it is convenient to disassemble and assemble the first housing 130 and the second housing 220 , and it is also convenient for the second portion 122 of the second electrical connector 120 to penetrate into the second accommodation cavity Q2 and make electrical contact with the third electrical connector 210 .

[0096] In some embodiments, please refer to Figure 7 and Figure 8 A first positioning groove C1 is provided on the first shell 130, and the second shell 220 includes a first shell portion 221 and a second shell portion 222 arranged around the first shell portion 221; the second shell portion 222 is snapped into the first positioning groove C1, and a second accommodating cavity Q2 is formed in the first shell portion 221, and a part of the first shell portion 221 is located in the first accommodating cavity Q1.

[0097] Alternatively, the second housing portion 222 and the first positioning groove C1 may both be annular structures.

[0098] Alternatively, the first housing portion 221 may also be in an annular structure.

[0099] The first housing 130 is provided with an insertion channel T communicating with the first accommodating cavity Q1 . The first housing portion 221 and the third electrical connector 210 in the first housing portion 221 pass through the insertion channel T and partially penetrate into the first accommodating cavity Q1 .

[0100] In this way, the second shell portion 222 can be snapped into the first positioning groove C1, and the first shell portion 221 and the third electrical connector 210 in the first shell portion 221 can also be partially inserted into the first accommodating cavity Q1, so that the third electrical connector 210 is in electrical contact with the second portion 122 in the first accommodating cavity Q1.

[0101] In some embodiments, the second connector 200 also includes an electrical isolator 230 disposed in the second accommodating cavity Q2, the electrical isolator 230 is connected to the third electrical connector 210, and along the axial direction of the first connecting hole K1, the distance between one end of the electrical isolator 230 close to the first electrical connector 110 and the first electrical connector 110 is greater than the distance between one end of the third electrical connector 210 close to the first electrical connector 110 and the first electrical connector 110.

[0102] The electrical isolator 230 refers to a component on the second connector 200 that is used to connect to the third electrical connector 210 and can perform electrical isolation. The electrical isolator 230 may be made of insulating material, for example, the electrical isolator 230 is made of plastic.

[0103] It can be understood that along the axial direction of the first connecting hole K1, the end of the electrical isolator 230 close to the first electrical connector 110 is arranged closer to the first electrical connector 110 than the end of the third electrical connector 210 close to the first electrical connector 110. In this way, the electrical isolator 230 can be used to reduce the possibility of fingers touching the third electrical connector 210, thereby improving the safety of the second connector 200.

[0104] In some embodiments, the electrical isolator 230 , the third electrical connector 210 and the wall of the second accommodating cavity Q2 define a second positioning groove C2 communicating with the first accommodating cavity Q1 , and the second portion 122 of the second electrical connector 120 is snap-fitted into the second positioning groove C2 .

[0105] The electrical isolator 230 may be annular, and the second positioning groove C2 may also be annular.

[0106] In this way, the second portion 122 of the second electrical connector 120 can be snapped into the second positioning groove C2, which is beneficial for aligning the central axes of the second connection hole K2 on the second electrical connector 120 and the third connection hole K3 on the third electrical connector 210, thereby improving the reliability of the electrical connection between the second portion 122 and the third electrical connector 210.

[0107] In some embodiments, the third electrical connector 210 is used to limit the movement of the electrical isolator 230 along the axis direction of the first connection hole K1 toward the side away from the second accommodation cavity Q2.

[0108] The electrical isolation member 230 may include a first electrical isolation portion 231 and a second electrical isolation portion 232 connected to each other, pointing to a side away from the second accommodation cavity Q2 along the axial direction of the first connection hole K1 , and the second electrical isolation portion 232 abuts against the third electrical connector 210 .

[0109] The electrical isolation member 230 may be in an inverted structure.

[0110] In some embodiments, the electrical isolator 230 is snap-connected to the third electrical connector 210. For example, the third electrical connector 210 is provided with a snap-in slot C3, and the second electrical isolator portion 232 of the electrical isolator 230 is snap-connected to the snap-in slot C3.

[0111] In the above two situations, the electrical isolator 230 can be stably connected to the third electrical connector 210 , so that the electrical isolator 230 can be better utilized to reduce the possibility of fingers touching the third electrical connector 210 , thereby improving the safety of the second connector 200 .

[0112] In some embodiments, the first connector 100 further includes a cover 140 . The first shell 130 is provided with an operating port connected to the first accommodating cavity Q1 and used to expose the first connecting hole K1 . The cover 140 is covered on the first shell 130 and used to open or close the operating port.

[0113] The cover 140 refers to a component of the first connector 100 that is used to cover the first housing 130 and to open or close the operation port.

[0114] The operation port refers to an opening provided on the first housing 130 and communicating with the first accommodating chamber Q1 .

[0115] Alternatively, one end of the cover body 140 may be hinged to the first shell 130 , and the other end may be snap-connected to the first shell 130 , so that the operation port can be opened or closed through the cover body 140 .

[0116] The cover body 140 can be opened first so that the fourth electrical connector can pass through the operating port and then penetrate the first connecting hole K1, the second connecting hole K2 and the third connecting hole K3 to electrically connect the first electrical connector 110, the second electrical connector 120 and the third electrical connector 210, which can improve the installation convenience of the fourth electrical connector. After the installation of the fourth electrical connector is completed, the operating port can be closed using the cover body 140, thereby preventing dust or water from the external environment from entering the first accommodating cavity Q1, which is beneficial to protecting components such as the first electrical connector 110, the second electrical connector 120 and the third electrical connector 210.

[0117] In some embodiments, the first electrical connector 110 is welded to the second electrical connector 120 , and the fourth electrical connector is passed through the first connection hole K1 , the second connection hole K2 , and the third connection hole K3 to electrically connect the first electrical connector 110 , the second electrical connector 120 , and the third electrical connector 210 .

[0118] Since the second electrical connector 120 can be initially positioned on the first electrical connector 110 in a preset posture, the possibility of the second electrical connector 120 being offset can be reduced during the welding process of the first electrical connector 110 and the second electrical connector 120, and the first electrical connector 110 and the second electrical connector 120 can be more stably electrically connected by using the first connecting hole K1 and the second connecting hole K2 that are aligned with each other, which is also beneficial for the fourth electrical connector to be inserted into the first connecting hole K1, the second connecting hole K2 and the third connecting hole K3, thereby facilitating the first electrical connector 110, the second electrical connector 120 and the third electrical connector 210 to be stably electrically connected together.

[0119] An embodiment of the present application provides a battery device 10 , including a battery cell and a connector assembly according to any of the above embodiments, wherein the battery cell is electrically connected to a third electrical connector 210 .

[0120] Since the first electrical connector 110, the second electrical connector 120 and the third electrical connector 210 are electrically connected together, the battery cell can be electrically connected to the electrical components of the vehicle 1 through the third electrical connector 210, the second electrical connector 120 and the first electrical connector 110, so that the battery cell can provide power to the electrical components of the vehicle 1.

[0121] An embodiment of the present application provides an electrical device, including the battery device 10 described above.

[0122] By way of example, the first connector 100 is a high voltage plug, and the second connector 200 is a high voltage connector adapted to the high voltage plug.
