[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model. In the present utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0053] Connectors are devices used to connect electrical equipment and transmit electrical energy. They are widely used in various industries. For example, in new energy vehicles, connectors are used to connect high-voltage components such as battery packs, drive motors, on-board chargers, and air conditioning compressors to realize the transmission and distribution of high-voltage electrical energy. In power systems, connectors are used to connect various high-voltage electrical equipment in power generation, transmission, transformation, and distribution.

[0054] To enable electrical connection between the connector and high-voltage components or high-voltage electrical equipment, the connector is provided with a plug, the high-voltage components or high-voltage electrical equipment is provided with a socket that is compatible with the connector plug, the socket is provided with a female terminal, and the connector plug includes a bus assembly and a male terminal for connecting to the female terminal of the socket.

[0055] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram illustrating the connection between the bus and the male terminal in related technologies. Figure 2 This is a schematic diagram illustrating the installation of the busbar and male terminal on the plastic base of the connector in related technologies. Figure 3 yes Figure 2 A cross-sectional view at point AA.

[0056] In related technologies, the busbar 1a and the male terminal 2a are electrically connected by screws. This split connection undoubtedly increases the assembly process, increases the difficulty of quality control, and is time-consuming and labor-intensive.

[0057] When using screws to connect and fix the busbar 1a to the mounting surface of the plastic base 3a, the busbar 1a is prone to twisting in the mounting plane as the screws are tightened, causing the holes on the busbar 1a to not align with the holes pre-set on the mounting surface. When other screws are driven in later, they are easily interfered with by the hole walls of the busbar 1a, causing the screws to jam.

[0058] The male terminal 2a is cylindrical in shape. It mates with the connector's plastic base 3a via a shaft-hole joint. This shaft-hole joint requires high assembly precision. Inappropriate assembly tolerances can easily cause the male terminal 1a and the connector's plastic base 3a to misfit. Both excessively loose and excessively tight fits result in serious assembly defects. For example, if the tolerance is too large, the male terminal 1a may become loose; if the tolerance is too small, the male terminal 1a may not be able to be installed in the plastic base 3a.

[0059] Based on the technical problems of increased assembly quality control and time-consuming and labor-intensive assembly caused by the separate connection method between the bus and the male terminal in the related technology, the embodiments of this utility model provide a bus assembly to solve at least some of the problems existing in the related technology.

[0060] Please see Figure 4 and Figure 5 , Figure 4 This is a cross-sectional schematic diagram of the bus assembly provided in an embodiment of this application. Figure 5 This is a schematic diagram of the bus structure provided in an embodiment of this application.

[0061] The bus assembly 1 provided in the embodiments of this utility model includes a base 11 and busbars (first busbar 12 and second busbar 13).

[0062] The base 11 can be made of insulating material. The base 11 has a mounting surface for connecting and fixing the busbar, and the mounting surface has a through groove 110.

[0063] Busbars can be made of copper, aluminum, or other conductive materials. Busbars are used to transmit electrical energy and have two integrally bent electrical connection parts. One electrical connection part is located on the mounting surface for connecting cables, and the other electrical connection part passes through the through groove 110 as a male terminal.

[0064] The bus assembly 1 provided in the embodiments of this utility model has a through groove 110 through the base 11, which is formed by the bus being configured as two integrally bent and connected electrical connection parts. One electrical connection part is provided on the mounting surface for connecting cables, and the other electrical connection part passes through the through groove 110 as a male terminal. Compared with the screw connection between the male terminal and the bus in the related technology, the embodiments of this application do not require the separate male terminal, thereby reducing the use of parts and simplifying the production and assembly process, reducing costs and increasing efficiency, which is conducive to the mass production and automated production of products.

[0065] Please see Figure 4In one embodiment, the mounting surface of the base 11 may include a first plane 111, a second plane 112 and a connecting surface 113, a through groove 110 is formed on the first plane 111, and the connecting surface 113 is bent to connect the first plane 111 and the second plane 112.

[0066] The first plane 111, the second plane 112, and the connecting surface 113 can be set to be non-coplanar according to the actual layout of the electrical components, so that the mounting surface can be fully arranged with the components, thereby reducing the space size of the connector.

[0067] For example, the first plane 111 and the second plane 112 are two sub-planes located on opposite sides of the mounting surface, and the connecting surface 113 is located between the first plane 111 and the second plane 112. The first plane 111 and the connecting surface 113 can be perpendicularly connected, and / or the second plane 112 and the connecting surface 113 can be perpendicularly connected.

[0068] For example, the first plane 111 and the connecting surface 113 of the mounting plane are perpendicularly connected, and the second plane 112 and the connecting surface 113 are perpendicularly connected; as another example, in one embodiment, the first plane 111 and the connecting surface 113 of the mounting plane are perpendicularly connected, while the second plane 112 and the connecting surface 113 are not perpendicularly connected (e.g., the second plane 112 and the connecting surface 113 tend to be perpendicularly connected); as yet another example, in one embodiment, the first plane 111 and the connecting surface 113 of the mounting plane are not perpendicularly connected (e.g., the first plane 111 and the connecting surface 113 tend to be perpendicularly connected), while the second plane 112 and the connecting surface 113 are perpendicularly connected. It should be noted that the above are merely exemplary descriptions of embodiments of this application and not exhaustive.

[0069] Please combine Figure 4 See also Figure 6 and Figure 7 , Figure 6 and Figure 7 These are schematic diagrams of the structures of two first busbars provided in the embodiments of this application.

[0070] The bus may include a first bus 12, which includes a first electrical connection 121 and a second electrical connection 122, and the first electrical connection 121 and the second electrical connection 122 are bent and connected.

[0071] A first electrical connection portion 121 is disposed on a first plane 111, and the first electrical connection portion 121 is used for electrically connecting a first electrode. Exemplarily, it can be attached to a mounting surface and connected to a base 11 by screws.

[0072] In one embodiment, the first electrical connection portion 121 has a notch 120 on the side near the first through groove 1101. The first electrical connection portion 121 also includes a first side 1211, a second side 1212 and a third side 1213 facing the notch 120. The two ends of the third side 1213 are bent and connected to the first side 1211 and the second side 1212 respectively. The second electrical connection portion 122 is connected to the third side 1213.

[0073] By providing a notch 120 on one side of the first electrical connection 121 and connecting the second electrical connection 122 to the third side 1213 within the notch 120, the second electrical connection 122 can avoid occupying additional space in the width direction (i.e., the direction perpendicular to the side) of the first electrical connection 121, thereby reducing the assembly space required for the first busbar 12 in the width direction.

[0074] The through slot 110 may include a first through slot 1101, through which the second electrical connection portion 122 extends. For example, in this embodiment of the application, the second electrical connection portion 122 is a quadrangular prism, so the first through slot 1101 can be a quadrilateral hole adapted to the quadrangular prism shape, so that the shape of the first through slot 1101 is adapted to the shape of the second electrical connection portion 122.

[0075] By setting the first through slot 1101 as a quadrilateral hole that matches the shape of the second electrical connection part 122, and the second electrical connection part 122 passing through the first through slot 1101, the advantage of this design is that it restricts the degree of freedom of rotation of the first busbar 12 within the mounting surface, which can play a pre-positioning role in the connection and fixation of the first busbar 12 on the base 11, so that the first busbar 12 can be accurately connected and fixed to the base 11, thereby greatly reducing the assembly difficulty of the first busbar 12 and improving the assembly efficiency.

[0076] In one embodiment, the first electrical connection portion 121 may include two oppositely disposed sides, with the first through groove 1101 disposed near one side, and the second electrical connection portion 122 bent and connected to the side near the first through groove 1101. See also... Figure 8 and Figure 9 This design allows the second electrical connection part 122 to pass through the first through slot 1101 and exit the base, avoiding unnecessary folding of the second electrical connection part 122.

[0077] Please combine Figure 4 See Figure 10 , Figure 10 These are schematic diagrams of the structure of the second bus provided in the embodiments of this application.

[0078] The busbar may further include a second busbar 13, which includes a third electrical connection portion 131 and a fourth electrical connection portion 132, which are bent and connected together. Part of the third electrical connection portion 131 is disposed on the second plane 112, for example, it can be attached to the second plane 112 and fixed to the base 11 with screws, for electrically connecting to a second electrode with a polarity opposite to that of the first electrode; another part of the third electrical connection portion 131 extends from the second plane 112 sequentially along the connecting surface 113 and the first plane 111 toward the second through groove 1102.

[0079] The through slot 110 may also include a second through slot 1102. The fourth electrical connection portion 132 extends through the second through slot 1102. Similar to the design of the first through slot 1101, in this embodiment of the application, the fourth electrical connection portion 132 is a quadrangular prism, so the second through slot 1102 can be set as a quadrilateral hole adapted to the quadrangular prism shape, so that the second through slot 1102 is adapted to the shape of the fourth electrical connection portion 132.

[0080] It should be noted that, in the embodiments of this application, the first electrode can be a positive electrode, and the second electrode is a negative electrode; it is understood that, when the first electrode is also a negative electrode, the second electrode is a positive electrode.

[0081] In this embodiment, the electrical connection portion and the through slot are interference-fitted. Specifically, the second electrical connection portion 122 is interference-fitted with the first through slot 1101, and the fourth electrical connection portion 132 is interference-fitted with the second through slot 1102. By setting the electrical connection portion and the through slot to be interference-fitted, the busbar can be effectively prevented from falling off.

[0082] In one embodiment, the first electrical connection portion 121 and the second electrical connection portion 122 can be formed by stamping and bending, and / or the third electrical connection portion 131 and the fourth electrical connection portion 132 can be formed by stamping and bending.

[0083] This manual uses the first busbar 12 as an example for illustration. The bending implementation method of the second busbar 13 can be modified based on the bending operation of the first busbar 12 according to the actual assembly requirements.

[0084] For example, a blank for forming the first busbar 12 can be obtained by stamping with a stamping device. The blank includes two parts for forming the first electrical connection part 121 and the second electrical connection part 122. Then, a bending device is used to apply force to the connection between the two parts to bend the blank, thereby forming the first busbar 12.

[0085] The bus provided in this application embodiment, which is formed by stamping and bending, has the advantages of simple structure, simple process, and reliable quality compared to the design of the bus in the related technology that requires screw connection between the bus and the male terminal to form an electrical connection. The first bus 12 and / or the second bus 13 can be mass-produced, which greatly saves production costs and improves production efficiency. Furthermore, since there is no screw connection, there is no additional contact resistance, which improves the current carrying capacity and eliminates the possibility of circuit breakage caused by loose or missing screws.

[0086] Please see Figure 4 In one embodiment, the seat 11 is further provided with a first enclosure 114, which encloses a first receiving chamber 1140. A first through groove 1101 communicates with the first receiving chamber 1140, and a second electrical connection part 122 is received in the first receiving chamber 1140; and / or the seat 11 is further provided with a second enclosure 115, which encloses a second receiving chamber 1150. A second through groove 1102 communicates with the second receiving chamber 1150, and a fourth electrical connection part 132 is received in the second receiving chamber 1150.

[0087] Specifically, the length of the second electrical connection 122 extending out of the base 11 is less than the height of the first enclosure 114, so that the first enclosure 114 can protect the second electrical connection 122; the length of the fourth electrical connection 132 extending out of the base 11 is less than the height of the second enclosure 115, so that the second enclosure 115 can protect the fourth electrical connection 132.

[0088] Please see Figure 11 and Figure 12 , Figure 11 This is a schematic diagram of the orthographic projection of the connector provided in the embodiment of this application. Figure 12 yes Figure 11 A cross-sectional view of section BB.

Figure 14 This is a schematic diagram of the connection of some electrical components provided in the embodiments of this application.

[0092] In one embodiment, the connector 100 may further include a first fuse 31 and a second fuse 32, and the cable may further include a third cable 23 and a fourth cable 24.

[0093] One end of the first fuse 31 and one end of the second fuse 32 are arranged side by side on the first plane 111, and the other end of the first fuse 31 and the other end of the second fuse 32 are located side by side directly above the second plane 112.

[0094] One end of the first cable 21, the second cable 22, the third cable 23, and the fourth cable 24 are arranged side by side on the second plane 112, directly below the other ends of the first fuse 31 and the second fuse 32, with the second cable 22 and the third cable 23 located between the first cable 21 and the fourth cable 24. That is, the projections of the two side-by-side fuses and the four side-by-side cables on the second plane 112 at least partially overlap.

[0095] The first cable 21 is connected to one end of the first fuse 31, and the other end of the first fuse 31 is connected to the first busbar 12. The fourth cable 24 is connected to one end of the second fuse 32, and the other end of the second fuse 32 is connected to the first busbar 12. The second cable 22 and the third cable 23 are connected to the second busbar 13.

[0096] In one embodiment, the connector 100 may further include a first adapter bus 41 and a second adapter bus 42. The first adapter bus 41 and the second adapter bus 42 have the same structure.

[0097] This specification uses the first adapter bus 41 as an example for illustration. The first adapter bus 41 may include two bent and connected ends, one end of which is fixed to the second plane 112 and the other end is flush with the first plane 111.

[0098] In one embodiment, the first cable 21 connects to one end of the first adapter bus 41 (i.e., the end fixed to the second plane 112), and the first fuse 31 connects to the other end of the first adapter bus 41 (i.e., the end flush with the first plane 111) and the first bus 12. The fourth cable 24 connects to one end of the second adapter bus 42 (i.e., the end fixed to the second plane 112), and the second fuse 32 connects to the other end of the second adapter bus 42 (i.e., the end flush with the first plane 111) and the first bus 12.

[0099] Specifically, the first electrical connection portion 121 of the first bus 12 may include two oppositely arranged ends. One end of the first fuse 31 is connected to one end of the first electrical connection portion 121, and the other end of the first fuse 31 is connected to the first transition bus 41. One end of the second fuse 32 is connected to the other end of the first electrical connection portion 121, and the other end of the second fuse 32 is connected to the second transition bus 42. The third electrical connection portion 131 of the second bus 13 may also include two oppositely arranged ends, with the second cable 22 connected to one end of the third connection portion 131 and the third cable 23 connected to the other end of the third connection portion 131.

[0100] In this embodiment, one end of the first fuse 31 and the second fuse 32 are arranged side by side on the first plane 111, and one end of the first cable 21, the second cable 22, the third cable 23 and the fourth cable 24 are arranged side by side on the second plane 112. The projections of the two side by side fuses and the four side by side cables on the second plane 112 at least partially overlap.
