[0002] The application belongs to the field of battery technology, and in particular relates to a high-voltage power distribution device, a battery device and electrical equipment. Background Art

[0003] With the development of science and technology, new energy electric vehicles are becoming increasingly popular. As one of the core components of electric vehicles, the battery device is the energy center of electric vehicles. For electric vehicles, battery technology is a key factor in their development.

[0004] The battery device is equipped with a high-voltage power distribution device, and the assembly efficiency of each component of the high-voltage power distribution device directly affects the overall assembly efficiency of the battery device.

[0005] The above statements are only used to provide background information related to the present application and do not necessarily constitute prior art. Summary of the Invention

[0006] The purpose of the embodiments of the present application is to provide a high-voltage power distribution device, a battery device, and an electrical device to improve the assembly efficiency of the high-voltage power distribution device.

[0007] The technical solution adopted in the embodiment of this application is:

[0008] In a first aspect, a high-voltage power distribution device is provided, comprising:

[0009] shell;

[0010] The electrical components are arranged in the housing;

[0011] A plurality of electrical connectors; wherein

[0012] The outer shell includes a first shell body, which includes an insulating shell body. Multiple electrical connectors are arranged at intervals and embedded in the shell body. Each electrical connector includes a connecting part and an output part. The connecting part is electrically connected to the electrical part. The shell body is also provided with an interface for adapting and plugging an external electrical connector. The output part extends to the interface and is used to electrically connect to the electrical connector plugged into the interface.

[0013] By adopting the technical solution of the embodiment of the present application, an interface adapted to an external electrical connector is provided on the first shell, so that the external electrical connector can be adapted to be inserted into the interface, and the output portion of each electrical connector is introduced into the internal space of the interface, and each output portion is exposed on the inner wall surface of the interface. When the external electrical connector is inserted into the interface, the connection terminal in the electrical connector is in electrical contact with the corresponding output portion, so that each electrical connector is connected to the external circuit through the corresponding electrical connector. In this way, the output portion of each electrical connector for connecting to the external circuit is led out into the interface, and an electrical connection is established by plugging the interface with the external electrical connector. Each output portion is accommodated in the interface and does not need to protrude beyond the surface of the shell body, thereby effectively reducing the risk of interference between the output portion and other adjacent components. In addition, there is no need to lead the output portion out through an adapter or wire, which helps to simplify the overall structure of the high-voltage power distribution device and improve assembly efficiency.

[0014] In some embodiments, the interface has a cavity penetrating the surface of the shell body, and the output portion is exposed at the cavity wall of the cavity.

[0015] By adopting the technical solution of this embodiment, the interface serves as the connection part for the internal electrical components of the high-voltage power distribution device to connect and interact with the external circuit. It has a cavity that can accommodate the output parts of various electrical connectors. The output parts are housed in the space defined by the cavity. The external connector can be positioned and connected with the interface through the cavity. The cavity can also protect the output parts. In addition, the output parts are exposed on the cavity wall surface of the cavity, so that they can contact with the terminals, pins, or contacts in the electrical connector inserted into the cavity to achieve electrical connection. In addition, the cavity passes through the side wall of the shell body, so that the external electrical connector can be directly plugged into the shell body and connected to the shell body, thereby helping to improve the connection reliability and stability between the external electrical connector and the interface, and improve the stability and reliability of power transmission.

[0016] In some embodiments, the interface is a groove recessed in the outer wall of the shell body.

[0017] By adopting the technical solution of this embodiment, the interface is designed as a groove. Compared to other interfaces that are directly exposed to the outside, the groove walls can provide a certain degree of protection for the internal output. When the matching external electrical connection is inserted into the groove, the surrounding walls can reduce the interference and erosion of the connection part by external collisions, dust, moisture, etc. to a certain extent, helping to maintain the stability and reliability of the connection and extend the service life of the connection components and the entire device. Moreover, the shape and size of the groove are designed to define the position of the connector connected to it, making it less likely to loosen or shift, and ensuring the normal functioning of various functions after connection.

[0018] In some embodiments, the housing further comprises a second housing, the electrical component is disposed in the second housing, and the first housing is connected to a side portion of the second housing along the first direction;

[0019] The interface is provided on a side of the shell body along a direction perpendicular to the first direction;

[0020] Alternatively, the interface is provided at the top of the shell body facing away from the second shell along the first direction.

[0021] By adopting the technical solution of this embodiment, the interface is arranged on the side or top of the shell body, so that the interface can avoid the connection area of ​​the first shell and the second shell, reducing structural interference while facilitating the plugging and unplugging operations of the external connector.

[0022] In some embodiments, the opening of the interface is arranged toward a direction intersecting with the first direction.

[0023] By adopting the technical solution of this embodiment, the opening is set along a direction intersecting with the first direction, so that the electrical connector is inserted into the interface along a direction intersecting with the first direction, that is, a direction intersecting with the assembly direction of the first shell and the second shell. The insertion of the electrical connector can effectively avoid the connection area of ​​the first shell and the second shell, reducing the risk of interference; at the same time, when the outside of the high-voltage distribution device is provided with a structure such as a liquid cooling plate along the first direction, the side wall of the interface can also block the opening of the interface in the first direction, thereby reducing the risk of condensed water entering the interface.

[0024] In some embodiments, the output portions are protruded at intervals within the interface and are disposed toward the opening of the interface.

[0025] By adopting the technical solution of this embodiment, the output part is suspended in the cavity of the interface, so that the interface as a whole can act as a male connector to adapt and plug into the external female connector. The overall structure of the interface is simpler to set up, and the connection method with the external electrical connector is also more direct.

[0032] In some embodiments, the number of sub-regions is greater than or equal to the number of outputs.

[0033] By adopting the technical solution of this embodiment, the number of sub-areas is determined by the number of insulating parts and the number of output parts. By setting a suitable number of insulating parts, the internal space of the interface is divided into a suitable number of sub-areas, so that each sub-area has exactly one output part. Alternatively, the number of sub-areas may be greater than the number of output parts, and there may be one or more sub-areas without an output part. The sub-area without an output part can be used as a spare space on the one hand, and as a guide space on the other hand, for adapting to the structure on the external connector and guiding the connector to connect with the interface.

[0104] High-voltage power distribution devices include various electrical connectors for power distribution management and signal acquisition. After connecting to the internal components of the high-voltage power distribution device, each electrical connector also needs to be connected to external connectors such as the control circuit and the battery management main control system to achieve current and signal transmission. In related technologies, each electrical connector is usually connected through a wiring harness, with one end of the wiring harness connected to the electrical connector and the other end connected to an external connector. This transmission method has many parts, resulting in high maintenance costs and a high probability of failure. In addition, the wiring harness is complex and takes up a lot of space, making it difficult to improve assembly efficiency.

[0105] Based on this, an embodiment of the present application provides a high-voltage power distribution device, which provides an interface adapted to an external electrical connector on a first shell, wherein the external electrical connector can be adapted to be inserted into the interface, and the output portion of each electrical connector is introduced into the internal space of the interface, and each output portion is exposed on the inner wall surface of the interface. When the external electrical connector is inserted into the interface, the connection terminal in the electrical connector is electrically contacted with the corresponding output portion, so that each electrical connector is connected to the external circuit through the corresponding electrical connector. In this way, the output portion of each electrical connector for connecting to the external circuit is led out into the interface, and an electrical connection is established by plugging the interface with the external electrical connector. Each output portion is accommodated in the interface and does not need to protrude beyond the surface of the shell body, thereby effectively reducing the risk of interference between the output portion and other adjacent components. In addition, there is no need to lead the output portion out through an adapter or a wire, which helps to simplify the overall structure of the high-voltage power distribution device and improve assembly efficiency.

[0121] In some embodiments, the housing 20 has a storage space 201 for accommodating the battery cell assembly 30.

[0125] Hereinafter, the high-voltage power distribution device 10 of the present application will be described in detail with reference to FIG. 3 to FIG. 12 and specific embodiments.

[0126] Please refer to Figures 3 to 5 and Figure 10 together. An embodiment of the present application provides a high-voltage power distribution device 10, which includes a shell 10a, an electrical component 103 and a plurality of electrical connectors 12, wherein the electrical component 103 is arranged in the shell 10a, the shell 10a includes a first shell 101, the first shell 101 includes an insulating shell body 11, and a plurality of electrical connectors 12 are embedded in the shell body 11, each electrical connector 12 includes a connecting portion 121 and an output portion 123, the connecting portion 121 is electrically connected to the electrical component 103, the shell body 11 is also provided with an interface 13 for adapting and plugging an external electrical connector, and the output portion 123 extends to the interface 13 and is used to be electrically connected to the electrical connector plugged into the interface 13.

[0127] It can be understood that in the embodiment of the present application, the high-voltage distribution device 10 refers to a collection of various components or assemblies used to receive, distribute and control electrical energy in the power distribution system. It can realize electrical energy distribution, not only reasonably distribute high-voltage electrical energy from the power supply end to multiple different power branches or loads, but also be used for circuit control, such as controlling the on and off of the circuit to realize the distribution and management of electrical energy. At the same time, it can also be used to provide protection functions in the circuit, such as automatically cutting off the circuit when a fault such as overload, short circuit, leakage occurs in the circuit, and can also be used to measure and detect energy in the circuit, such as measuring and monitoring parameters such as current, voltage, and power in the circuit to understand the operating status of the circuit. For example, the high-voltage distribution device 10 can be used in a battery device to distribute and manage the electrical energy of the battery cell assembly in the battery device. Electrical components such as relays 1031, circuit breakers, contactors, fuses, circuit breakers, current transformers, and voltage transformers can be set in the high-voltage distribution device 10 to realize relevant control of the circuit.

[0128] In the embodiment of the present application, the high-voltage power distribution device 10 includes a first shell 101, wherein the first shell 101 can be the outer shell 10a of the entire high-voltage power distribution device 10, or it can also be a part of the outer shell 10a structure, which plays a role in protecting internal structural components, or the first shell 101 can also be the inner shell structure of the internal space of the high-voltage power distribution device 10 to play a role in supporting internal electrical components 103 and other structural components. The first shell 101 includes a shell body 11 and a plurality of electrical connectors 12, that is, the first shell 101 has at least two parts, the shell body 11 and the electrical connectors 12. The shell body 11 is the main part of the first shell 101, which is an insulating part made of insulating material. Each electrical connector 12 is embedded in the interior of the shell body 11, and a portion of each electrical connector 12 is embedded in the interior of the shell body 11, that is, a portion of each electrical connector 12 is wrapped by the shell body 11 and buried in the internal space of the shell body 11. The electrical connectors 12 are spaced apart from each other and isolated from each other, and can be insulated from each other. At the same time, the shell body 11 can also provide good protection for the portion of the internal electrical connector 12 buried in the shell body 11, reducing the adverse effects of external environmental factors such as mechanical collisions and chemical corrosion. Among them, the shell body 11 can be made of inorganic insulating materials, organic insulating materials, and composite insulating materials. For example, the material of the shell body 11 can be ceramic, glass, mica, plastic, rubber, and epoxy glass fiber cloth composite materials.

[0129] On this basis, each electrical connector 12 includes a connecting portion 121, which is used to electrically connect the electrical component 103 of the high-voltage distribution device 10. The connecting portion 121 can be embedded in the interior of the shell body 11 or the connecting portion 121 can be exposed on the outside of the shell body 11. In some exemplary embodiments, the connecting portion 121 is exposed on the outside of the shell body 11, and the connecting portion 121 and the corresponding electrical component 103 can be connected by welding, crimping or locking. In other examples, the connecting portion 121 can be embedded in the interior of the shell body 11, and holes can be opened at corresponding positions of the connecting portion 121 and the shell body 11, and can be connected to the electrical component 103 by plugging, locking, etc.; each electrical connector 12 also includes an output portion 123, that is, the electrical connector 12 includes at least two parts, the connecting portion 121 and the output portion 123, and the output portion 123 is used to connect to an external circuit. In this way, the electrical connector 12 can be tightly combined with the shell body 11, so that the electrical connector 12 can be stably and firmly installed on the shell body 11, and at the same time, the electrical connection function between the internal electrical parts 103 of the high-voltage distribution device 10 and the external circuit can be realized through the connecting part 121 and the output part 123.

[0130] Among them, it can be understood that the electrical components 103 in the high-voltage distribution box include but are not limited to main relays, pre-charge relays, pre-charge resistors, fuses, current sensors, and other types of connectors, connecting pieces or connection points for electrical connection.

[0131] In this embodiment, the shell body 11 is also provided with an interface 13 for adapting and plugging an external electrical connector, and the output part 123 of each electrical connector 12 for connecting to the external circuit of the high-voltage distribution device 10 extends into the interface 13. In this way, an interface 13 adapted to the external electrical connector is provided on the shell body 11, and the electrical connector connected to the external circuit can be adapted and inserted into the interface 13, and the output part 123 of each electrical connector 12 is introduced into the internal space of the interface 13, and the output part 123 is exposed on the inner wall surface of the interface 13. When the external electrical connector is inserted into the interface 13, the connection terminal in the electrical connector is electrically contacted with the corresponding output part 123, so that each electrical connector 12 is connected to the external circuit through the corresponding electrical connector.

[0132] The high-voltage power distribution device 10 of the present embodiment is provided with an interface 13 on the first housing 101 that is adapted to be compatible with an external electrical connector. The external electrical connector can be adapted to be inserted into the interface 13, and the output portion 123 of each electrical connector 12 is introduced into the internal space of the interface 13. Each output portion 123 is exposed on the inner wall surface of the interface 13. When the external electrical connector is inserted into the interface 13, the connection terminal in the electrical connector electrically contacts the corresponding output portion 123, thereby connecting each electrical connector 12 to the external circuit through the corresponding electrical connector. In this way, the output portion 123 of each electrical connector 12 for connecting to the external circuit is led out into the interface 13, and an electrical connection is established by plugging the interface 13 with the external electrical connector. Each output portion 123 is housed in the interface 13 without protruding from the surface of the housing body 11, thereby effectively reducing the risk of interference between the output portion 123 and other adjacent components. In addition, there is no need to lead the output portion 123 through an adapter or wire, which helps to simplify the overall structure of the high-voltage power distribution device 10 and improve assembly efficiency.

[0133] In some embodiments, as shown in FIG. 3 to FIG. 5 , the interface 13 has a cavity 131 that passes through the surface of the shell body 11 , and the output portion 123 is exposed at the cavity wall of the cavity 131 .

[0134] In this embodiment, the interface 13 serves as the connection portion 121 for connecting and interacting the internal electrical components 103 of the high-voltage power distribution device 10 with the external circuit. The interface 13 has a cavity 131. The cavity 131 can accommodate the output portion 123 of each electrical connector 12. The output portion 123 is housed in the space defined by the cavity 131. The external connector can be positioned and connected to the interface 13 through the cavity 131. The cavity 131 can also protect the output portion 123. In addition, the output portion 123 is exposed on the wall surface of the cavity 131, so that it can contact with the terminal, pin, or contact in the electrical connector inserted into the cavity 131 to achieve electrical connection. In addition, the cavity 131 passes through the side wall of the shell body 11, so that the external electrical connector can be directly plugged into the shell body 11 and connected to the shell body 11, thereby helping to improve the connection reliability and stability between the external electrical connector and the interface 13, and improve the stability and reliability of power transmission.

[0135] In some embodiments, as shown in FIG. 3 to FIG. 5 , the interface 13 is a groove recessed in the outer wall of the shell body 11 .

[0136] In this embodiment, the interface 13 is in the form of a groove, wherein the groove is a structure formed by inwardly recessing the outer wall of the shell body 11. The groove-shaped interface 13 can be integrally formed when the shell body 11 is formed, or after the shell body 11 is formed, a recessed area can be carved out of the shell body 11 wall using a process such as punching or cutting to serve as the interface 13. Thus, the design of the interface 13 as a groove provides a certain degree of protection for the internal output portion 123, compared to other interfaces 13 that are directly exposed to the outside. When the matching external electrical connector is inserted into the groove, the surrounding walls can reduce interference and erosion of the connection portion 121 by external collisions, dust, moisture, etc., to a certain extent, helping to maintain the stability and reliability of the connection and extend the service life of the connection portion 121 and the entire device. Moreover, the shape and size of the groove can be designed to define the position of the connector to which it is connected, making it less likely to loosen or shift, thereby ensuring the normal functioning of various functions after connection.

[0137] In some embodiments, as shown in Figures 3, 4 and 10, the housing 10a also includes a second shell 102, the electrical component 103 is arranged on the second shell 102, the first shell 101 is connected to the side of the second shell 102 along a first direction, and the interface 13 is arranged on the side of the shell body 11 along a direction perpendicular to the first direction.

[0138] In this embodiment, in addition to the first shell 101, the shell 10a also includes a second shell 102. The second shell 102 is connected to the first shell 101 to form a shell structure. The electrical component 103 is arranged in the second shell 102. The second shell 102 provides installation and accommodation space for each electrical component 103. The first shell 101 is connected to the side of the second shell 102 along a first direction, wherein the first direction can be the thickness direction of the first shell 101, such as the direction shown by the arrow F1 in the figure. The interface 13 is arranged on the side of the shell body 11 along a direction perpendicular to the first direction (the direction shown by the arrow F2 in the figure), so that the interface 13 can avoid the connection area between the first shell 101 and the second shell 102, reduce structural interference, and facilitate the plugging and unplugging operations of the external connector.

[0139] In other embodiments, the interface 13 may also be provided at the top of the housing body 11 along the first direction away from the second housing 102. In this way, the interface 13 is provided at the top of the housing body 11 in a direction perpendicular to the first direction and away from the second housing 102, so that the interface 13 can also effectively avoid the connection area between the first housing 101 and the second housing 102, reducing structural interference and facilitating the insertion and removal of external connectors.

[0140] In some embodiments, as shown in FIG. 3 , FIG. 4 , and FIG. 10 , the opening 130 of the interface 13 is disposed toward a direction intersecting with the first direction.

[0141] Among them, the setting position of the opening 130 of the interface 13 determines the direction in which the external electrical connector is inserted into the interface 13. The opening 130 is set along a direction intersecting with the first direction, so that the electrical connector is inserted into the interface 13 along a direction intersecting with the first direction, that is, a direction intersecting with the assembly direction of the first shell 101 and the second shell 102. The insertion of the electrical connector can effectively avoid the connection area of ​​the first shell 101 and the second shell 102, reducing the risk of interference; at the same time, when the outside of the high-voltage distribution device 10 is provided with a structure such as a liquid cooling plate along the first direction, the side wall of the interface 13 can also block the opening 130 of the interface 13 in the first direction, thereby reducing the risk of condensation water entering the interface 13.

[0142] In a specific embodiment, the opening 130 of the interface 13 is oriented perpendicular to the first direction.

[0143] In some embodiments, as shown in FIG. 4 to FIG. 8 , the output portions 123 are protruded at intervals within the interface 13 and are disposed toward the opening 130 of the interface 13 .

[0144] In this embodiment, the output portion 123 is suspended in the cavity 131 of the interface 13, so that the interface 13 as a whole can act as a male connector to be plugged into an external female connector. The overall structure of the interface 13 is simpler, and the connection method with the external electrical connector is also more direct.

[0145] In some embodiments, as shown in FIG. 4 to FIG. 6 , the spacing distance a1 between two adjacent output portions 123 is greater than 3 mm.

[0146] In a specific embodiment, in the interface 13 , the spacing between two adjacent output portions 123 is greater than 3 mm, that is, when there is no insulating member separating the two adjacent output portions 123 , the electrical gap is greater than 3 mm to meet electrical safety requirements.

[0147] Exemplarily, the spacing distance between two adjacent output parts 123 can be 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, etc., or, when the output part 123 is connected to a high-voltage circuit, the electrical gap between two adjacent output parts 123 can be 9.5mm, 10mm, 11mm, or even larger.

[0148] In other embodiments, as shown in FIG. 7 and FIG. 8 , an insulating portion 16 is further provided between two adjacent output portions 123 , and the two adjacent output portions 123 are electrically isolated by the insulating portion 16 .

[0149] In this way, an insulating part 16 is set between two adjacent output parts 123 to separate them. The two output parts 123 are electrically isolated by the insulating part 16. Especially for some situations with higher voltages, setting the insulating part 16 can effectively shorten the spatial distance between the two adjacent output parts 123, thereby helping to reduce the size of the interface 13 and making the structure of the interface 13 more compact.

[0150] In some embodiments, as shown in Figures 7 to 9, the peripheral side walls of the insulating portion 16 are fitted and connected to the inner side walls of the interface 13, and the insulating portion 16 divides the internal space of the interface 13 into multiple sub-areas 1311, and an output portion 123 is correspondingly provided in each sub-area 1311.

[0151] In this embodiment, it can be understood that the insulating portion 16 is a plate-like or sheet-like structure having a certain thickness, and the peripheral sidewalls of the insulating portion 16 refer to the side portions surrounding the four edges of the insulating portion 16. The peripheral sidewalls of the insulating portion 16 are closely connected to the inner sidewalls of the interface 13, which means that the peripheral sidewalls of the insulating portion 16 located within the internal space of the interface 13 are tightly connected to the corresponding inner sidewalls of the interface 13, and there is no gap between the mutually contacting walls, so that the insulating properties of the insulating portion 16 can be utilized to effectively block current and reduce the risk of leakage.

[0152] In this way, the internal space of the interface 13 is divided into multiple sub-areas 1311 by the insulating part 16, and an output part 123 is correspondingly set in each sub-area 1311. The output parts 123 in two adjacent sub-areas 1311 are effectively separated by the insulating part 16, thereby reducing the risk of electrical interference in the two adjacent sub-areas 1311 and further improving the electrical safety of the interface 13.

[0153] It should be noted that, in a specific embodiment, the number of sub-areas 1311 can be two, three or more, and the number of sub-areas 1311 is determined by the number of insulating parts and the number of output parts 123. By setting an appropriate number of insulating parts, the internal space of the interface 13 is divided into an appropriate number of sub-areas 1311, so that each sub-area 1311 corresponds to exactly one output part 123. Alternatively, the number of sub-areas 1311 can be greater than the number of output parts 123, and there is one or more sub-areas 1311 in which no output part 123 is set. The sub-area 1311 without an output part 123 can be used as a spare space on the one hand, and as a guide space on the other hand, for adapting to the structure on the external connector and guiding the connector to connect with the interface 13.

[0154] In some embodiments, as shown in Figures 7 to 9, the interface 13 has a first wall 1312 arranged opposite the opening 130, the output portion 123 and the insulating portion 16 both protrude from the first wall 1312, and the protruding size of the insulating portion 16 is larger than the protruding sizes of the two adjacent output portions 123.

[0155] In this way, the protruding size of the insulating portion 16 is larger than the protruding size of the two adjacent output portions 123, and the insulating portion 16 can more fully cover and separate the adjacent output portions 123 in space. The current needs to pass through the corresponding insulating portion 16 to reach the output portion 123 on one side from the output portion 123 on the other side, thereby achieving insulation.

[0156] In a specific embodiment, as shown in Figures 7 to 9, the multiple output portions 123 are arranged in sequence and spaced apart along a direction perpendicular to the direction in which the first wall 1312 points toward the opening 130 (the direction indicated by arrow F3 in the figure), and the insulating portion 16 is provided parallel to the output portions 123; along a direction perpendicular to the direction in which the first wall 1312 points toward the opening 130 (the direction indicated by arrow F4 in the figure), the spacing distances between the insulating portion 16 and two adjacent output portions 123 are L1 and L2, respectively, and the thickness of the insulating portion 16 is L3; along the direction in which the first wall 1312 points toward the opening 130, the protrusion dimensions of the insulating portion 16 relative to the two adjacent output portions 123 are L4 and L5, respectively; wherein the sum of L1, L2, L3, L4, and L5 is greater than 3 mm.

[0157] In this embodiment, as shown in Figures 7 to 9, when an insulating portion 16 is provided between two adjacent output portions 123, the creepage distance between the two adjacent output portions 123 includes: a spacing distance dimension L1 between the insulating portion 16 and one adjacent output portion 123, a spacing distance dimension L2 between the insulating portion 16 and another adjacent output portion 123, a thickness dimension L3 of the insulating portion 16, a protrusion dimension L4 of the insulating portion 16 relative to one adjacent output portion 123, and a protrusion dimension L5 of the insulating portion 16 relative to the other adjacent output portion 123. If the sum of these five dimensions is greater than 3 mm, the creepage distance between the two adjacent output portions 123 separated by the insulating portion 16 can meet the requirement of being greater than 3 mm.

[0158] In a specific embodiment, when two electrical connectors 12 corresponding to two adjacent output portions 123 are connected to a low-voltage circuit, the creepage distance between the two output portions 123 is greater than 3 mm to meet insulation requirements.

[0159] For example, the creepage distance between two adjacent output parts 123 may be 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, etc.

[0160] In other embodiments, the sum of L1 , L2 , L3 , L4 and L5 is greater than 9.5 mm, that is, the creepage distance between two adjacent output parts 123 is greater than 9.5 mm.

[0161] In this way, when the two electrical connectors 12 corresponding to two adjacent output portions 123 are connected to a circuit with a higher voltage, the creepage distance between the two output portions 123 is greater than 9.5 mm, thereby meeting the insulation requirement.

[0162] For example, when two adjacent electrical connectors 12 are connected to a circuit with a voltage greater than 220V and less than or equal to 660V, the creepage distance between two adjacent output parts 123 can be 9.6mm, 10mm, 10.5mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm or 18mm, etc.

[0163] In other embodiments, the sum of L1 , L2 , L3 , L4 and L5 is greater than 19 mm, that is, the creepage distance between two adjacent output parts 123 is greater than 9.5 mm.

[0164] In this way, when two adjacent electrical connectors 12 are connected to a larger voltage loop, the creepage distance between the two output portions 123 is greater than 19 mm to meet insulation requirements.

[0165] For example, when two adjacent electrical connectors 12 are connected in a circuit with a voltage greater than 660V, the creepage distance between two adjacent output parts 123 can be a larger size such as 19.1mm, 19.5mm, 19.8mm, 20mm, 20.5mm, 21mm, 21.5mm, 22mm, 22.5mm or 23mm.

[0166] In some embodiments, as shown in FIG. 7 and FIG. 9 , the shell body 11 is further provided with a guide structure 111 , and the guide structure 111 is used to guide an external electrical connector to be adapted to be inserted into the interface 13 .

[0167] The guide structure 111 is used to guide the external connector to be inserted into the interface 13. The guide structure 111 can be directly provided in the interface 13, or can be an independent structural member on the shell body 11, and installed at the interface 13 by bonding, plugging, etc.

[0168] The guide ribs 1111 are provided in the interface 13 to cooperate with the corresponding structure on the external electrical connector, so as to facilitate the plugging of the external electrical connector, thereby improving the connection efficiency of the external electrical connector to a certain extent and simplifying the connection operation.

[0169] In a specific embodiment, as shown in Figures 7 and 9, the guide structure 111 includes guide ribs 1111 protruding from the inner wall surface of the interface 13. The guide ribs 1111 are arranged parallel to the output portion 123. Thus, the guide ribs 1111 are arranged in the interface 13 in the same direction as the extension direction of the output portion 123. The guide ribs 1111 guide the external electrical connector along the protruding direction of the output portion 123 for insertion and removal.

[0170] In a specific embodiment, as shown in Figures 7 and 9 , along the arrangement direction of the output portions 123 (in the direction indicated by arrow F4 in the figures), guide ribs 1111 are provided on at least one side of each insulating portion 16. These ribs 1111 are arranged parallel to the insulating portions 16 and spaced apart, forming guide grooves 1112 between adjacent insulating portions 16. The guide grooves 1112 can be used to mate with protrusions provided on an external electrical connector to further guide the electrical connector along the extension direction of the output portions 123 for insertion into the board.

[0171] In some embodiments, as shown in Figures 7 and 8, the inner wall surface of the interface 13 is further provided with a plurality of reinforcing ribs 112 spaced in parallel, and the reinforcing ribs 112 are arranged in parallel and spaced from the guide ribs 1111. The reinforcing ribs 112 are provided on the side wall of the interface 13 to improve the structural strength of the interface 13.

[0172] [Corrected on 18.02.2025 according to Rule 91] In some embodiments, as shown in Figures 3, 7, and 10 to 12, the electrical connector 12 includes a first connector 124 and a second connector 125, and the interface 13 includes a first interface 132 for adapting and plugging in an external first connector; wherein, the connecting portion 121 includes a first connecting portion 1211 and a second connecting portion 1212, and the output portion 123 includes a first output portion 1231 and a second output portion 1232, the first connecting portion 1211 and the first output portion 1231 are spaced apart on the first connector 124, and the second connecting portion 1212 and the second output portion 1232 are spaced apart on the second connector 125, the first connecting portion 1211 and the second connecting portion 1212 are electrically connected to different electrical components 103 respectively, and the first output portion 1231 and the second output portion 1232 both extend into the first interface 132 and are used to be electrically connected to the first connector.

[0173] In this embodiment, the electrical connector 12 includes two connectors with different functions, a first connector 124 and a second connector 125. The first connector 124 includes a first connecting part 1211 and a first output part 1231, and the second connector 125 includes a second connecting part 1212 and a second output part 1232. The first connector 124 is electrically connected to a connection end of an electrical part 103 of the high-voltage distribution device 10 through the first connecting part 1211, and is electrically connected to a connection terminal or pin or contact in an external electrical connector through the first output part 1231. On this basis, the second connector 125 is electrically connected to another connection end of the same electrical part 103 of the high-voltage distribution device 10 through the second connecting part 1212, and is electrically connected to another connection terminal or pin or contact in the external electrical connector through the second output part 1232. In this way, the first connector 124 and the second connector 125 are used in combination to connect the electrical connection connected to them to the external circuit and realize current transmission between the external circuit and the electrical part 103.

[0174] In a specific embodiment, as shown in FIG10 , there are multiple first connectors 124 and multiple second connectors 125, and the number of first connectors 124 and second connectors 125 are equal. In this way, the first connectors 124 and the second connectors 125 are used in groups to connect different electrical components 103 to an external circuit.

[0175] In a specific embodiment, the first output portions 1231 of the plurality of first connectors 124 are arranged in a staggered arrangement with the second output portions 1232 of the plurality of second connectors 125. That is, the plurality of output portions 123 are arranged in a staggered arrangement with one first output portion 1231, one second output portion 1232, one first output portion 1231, and one second output portion 1232, so that two adjacent output portions 123 can be used to connect the same electrical component 103 to the same external circuit.

[0176] In other embodiments, as shown in Figures 7 to 9 , the first output portions 1231 of the plurality of first connectors 124 are arranged continuously and spaced apart, and the second output portions 1232 of the plurality of second connectors 125 are arranged continuously and spaced apart. That is, the plurality of first output portions 1231 are concentrated in one area, and the plurality of second output portions 1232 are concentrated in another area. This facilitates distinguishing between the first output portions 1231 and the second output portions 1232, allowing centralized maintenance and management of the first output portions 1231 or the second output portions 1232.

[0177] In some embodiments, as shown in Figure 10, the electrical component 103 includes a relay 1031, and the relay 1031 has a first terminal 10311 and a second terminal 10312 respectively electrically connected to the opposite ends of the coil, the first connecting portion 1211 is electrically connected to the first terminal 10311, and the second connecting portion 1212 is electrically connected to the second terminal 10312.

[0178] It can be understood that relay 1031 is a switching device primarily used to control the switching of a circuit to enable normal operation of the circuit. Relay 1031 includes a coil. When energized, the coil can generate a magnetic field or achieve functions such as electromagnetic induction. Relay 1031 also has a first terminal 10311 and a second terminal 10312. The first terminal 10311 and the second terminal 10312 are used to connect to the positive and negative poles of an external power supply device to power the coil. The coil, the first terminal 10311, and the second terminal 10312 are all electrical components 103.

[0179] In this way, the first connection part 1211 of the first connection member 124 is electrically connected to the first terminal 10311, and the second connection part 1212 of the second connection member 125 is electrically connected to the second terminal 10312, and then the corresponding first output part 1231 and the second output part 1232 are electrically connected to the electrical connector of the external power supply, so that the external power supply and the coil of the relay 1031 can be connected, so that the external power supply is used to power the coil.

[0180] In some embodiments, the relay 1031 includes at least one of a main positive relay, a main negative relay, and a pre-charge relay.

[0181] In a specific embodiment, the high-voltage power distribution device 10 may include any one or more of a main positive relay, a main negative relay, and a pre-charge relay, or may include multiple main positive relays, multiple main negative relays, and multiple pre-charge relays. Furthermore, the number of first connectors 124 and the number of second connectors 125 are both greater than or equal to the number of relays 1031, so that each relay 1031 can be connected to an external power source via a set of first connectors 124 and second connectors 125.

[0182] In some examples, as shown in FIG10 , the relay 1031 may include a main relay and a pre-charge relay, etc., wherein the main relay includes a main positive relay for being set on the positive side of the high-voltage system and a main negative relay for being set on the negative side of the high-voltage system. In the high-voltage system, automatic control of the circuit can be achieved by controlling the switching state of the main relay.

[0183] In other embodiments, the relay 1031 may also include a pre-charge relay. In the battery device, the pre-charge relay is a relay 1031 that controls the opening and closing of the pre-charge circuit, that is, before the main relay works, the pre-charge circuit is turned on for self-test. The pre-charge relay can play a pre-charging role in the circuit. When the vehicle and other electrical devices are started, the capacitor can be fully charged by pre-charging, and when the system switch is started, the charge of the capacitor is slowly released into the switch circuit to reduce the load and voltage drop of the switch. The pre-charge relay achieves smoother power transmission and longer battery life by controlling the charging and discharging process of the capacitor.

[0184] [Corrected on 18.02.2025 according to Rule 91] In some embodiments, as shown in Figures 3, 7, and 10 to 12, the electrical connector 12 also includes a plurality of third connectors 126, the interface 13 also includes a second interface 133 for adapting and plugging an external second connector, and the electrical component 103 also includes a plurality of high-voltage sampling components 1032; wherein, the connecting portion 121 also includes a third connecting portion 1213, the output portion 123 includes a third output portion 1233, and each third connector 126 is respectively provided with a third output portion 1233 and at least one third connecting portion 1213 at intervals, and each third connecting portion 1213 is connected to the high-voltage sampling component 1032 one-to-one, and each third output portion 1233 extends into the second interface 133 and is used to be electrically connected to the second connector.

[0185] In this embodiment, the third connection portion 1213 of each third connector 126 is connected to the high-voltage circuit within the high-voltage power distribution device 10, and is electrically connected to each high-voltage sampling element 1032 provided in the high-voltage circuit, thereby collecting voltage information at the corresponding position of the high-voltage circuit. The second interface 133 can be used to adapt and plug with an external second connector, wherein the second connector can be a connector provided in the control system of the battery device, such as a connector provided in the battery management system, so that the corresponding collected voltage signal is transmitted to the external control system through the third output portion 1233. In this way, the second interface 133 is provided on the shell body 11, and the third output portion 1233 of the third connector 126 used for connecting to each high-voltage sampling point extends into the second interface 133, thereby connecting to the electrical connector of the external control system through the second interface 133 to realize voltage signal transmission. At the same time, the first interface 132 and the second interface 133 can also spatially distinguish and isolate the electrical connectors 12 with different functions, which also helps to reduce the risk of electrical interference and connection confusion.

[0186] Exemplarily, the high-voltage sampling component 1032 may include a high-voltage sampling copper bus, and the first connecting portion 1211 is connected to the high-voltage sampling copper bus in the high-voltage distribution device 10, for example, connected to the high-voltage bus bar connected to the output end of the battery cell group, or connected to the high-voltage bus bar connected to the input end of the battery cell group, or connected to the high-voltage bus bar connected to the high-voltage contact of the relay 1031, etc.

[0187] In some embodiments, as shown in FIG. 9 and FIG. 10 , a third connecting member 126 includes a third connecting portion 1213 , and a third connecting member 126 is electrically connected to a high-voltage sampling member 1032 in a one-to-one correspondence.

[0188] In this embodiment, a third connector 126 includes a third connecting portion 1213, and a third connector 126 is electrically connected to a high-voltage sampling component 1032 through a third connecting portion 1213, so that the voltage signals at each high-voltage sampling position are led out one by one. One high-voltage sampling position corresponds to one high-voltage sampling component 1032 and one third connector 126. The number of third connectors 126 is equal to the number of high-voltage sampling components 1032, and the number of third output portions 1233 is equal to the number of high-voltage sampling points.

[0189] For example, when there are three high-voltage sampling sites in the high-voltage distribution box, the second interface 133 has three corresponding third output parts 1233; or, when there are five or six high-voltage sampling sites in the high-voltage distribution box, the second interface 133 has five or six corresponding third output parts 1233.

[0190] In other embodiments, as shown in Figures 9 and 10, a third connecting member 126 includes two third connecting portions 1213 arranged at intervals, and the two third connecting portions 1213 are respectively connected to two high-voltage sampling components 1032, and the third connecting member 126 is electrically connected to the two high-voltage sampling components 1032.

[0191] In this embodiment, a third connector 126 includes two third connecting parts 1213. A third connector 126 is electrically connected to a high-voltage sampling component 1032 through one third connecting part 1213, and is electrically connected to another high-voltage sampling component 1032 through another third connecting part 1213. The voltage signals of two high-voltage sampling points connected by two different third connecting parts 1213 on the same third connector 126 do not need to be collected at the same time. In this way, the voltage signals at each high-voltage sampling position can also be led out one by one through the third output parts 1233 of each third connector 126.

[0192] In a specific embodiment, the high-voltage power distribution device 10 has a main circuit and a pre-charge circuit. One of the third connection portions 1213 provided on the same third connector 126 is electrically connected to a high-voltage sampling component 1032 provided in the main circuit, and the other third connection portion 1213 is electrically connected to a high-voltage sampling component 1032 provided in the pre-charge circuit. In this way, the pre-charge circuit and the main circuit are not connected at the same time. One of the two third connection portions 1213 on the same third connector 126 is electrically connected to a high-voltage sampling point on the main circuit, and the other is electrically connected to a high-voltage sampling component on the pre-charge circuit. The two sampling positions corresponding to the two third connection portions 1213 are not sampled at the same time, and the two third connection portions 1213 are not connected at the same time. In this way, the high-voltage sampling components 1032 at two high-voltage sampling positions in the pre-charge circuit and the main circuit that do not need to be sampled simultaneously are connected to different third connection portions 1213 on the same third connector 126, thereby reducing the number of third connectors 126 and helping to simplify the structure.

[0193] In some embodiments, the first interface 132 and the second interface 133 are spaced apart, and the spacing distance between the first interface 132 and the second interface 133 is greater than 9.5 mm.

[0194] Thus, when the third connector 126 is connected to a circuit with a higher voltage, the creepage distance between the first interface 132 and the second interface 133 is greater than 9.5 mm, thereby meeting the insulation requirement.

[0195] Exemplarily, when the third connecting member 126 is connected to a circuit with a voltage greater than 220V and less than or equal to 660V, the creepage distance between the first interface 132 and the second interface 133 can be 9.6mm, 10mm, 10.5mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm or 18mm, etc.

[0196] In other embodiments, the distance between the first interface 132 and the second interface 133 is greater than 19 mm.

[0197] Thus, when the third connector 126 is connected to a circuit with a higher voltage, the creepage distance between the first interface 132 and the second interface 133 is greater than 19 mm to meet insulation requirements.

[0198] For example, when the third connector 126 is connected to a circuit with a voltage greater than 660 V, the creepage distance between the first interface 132 and the second interface 133 can be a larger size such as 19.1 mm, 19.5 mm, 19.8 mm, 20 mm, 20.5 mm, 21 mm, 21.5 mm, 22 mm, 22.5 mm or 23 mm.

[0199] In some embodiments, the first interface 132 and the second interface 133 are located on the same side of the housing body 11 .

[0200] In this embodiment, the first interface 132 and the second interface 133 are arranged on the same side of the shell body 11, that is, the first interface 132 and the second interface 133 are plugged into different external electrical connectors on the same side of the high-voltage distribution device 10. This facilitates centralized connection with external electrical connectors, simplifies the layout of external connection lines, reduces line crossing and confusion, and improves the regularity and reliability of the connection.

[0201] Among them, it can be understood that when the first interface 132 and the second interface 133 are arranged on the same side of the shell body 11, the requirements of electrical clearance and creepage distance between the first interface 132 and the second interface 133 need to be met, so that the first interface 132 and the second interface 133 cannot be electrically conductive.

[0202] In other embodiments, as shown in Figures 3 and 10 to 12, different from the above embodiments, the shell body 11 has multiple different sides, and the first interface 132 and the second interface 133 are located on different sides of the shell body 11. For example, the first interface 132 and the second interface 133 are located on adjacent sides of the shell body 11, or the first interface 132 and the second interface 133 are located on opposite sides of the shell body 11.

[0203] In this embodiment, the first interface 132 and the second interface 133 are arranged on different sides of the shell body 11, that is, the first interface 132 is arranged on one side of the shell body 11, and the second interface 133 is arranged on the other side of the shell body 11. The first interface 132 and the second interface 133 are spatially located on different sides of the shell body 11. In this way, the first interface 132 and the second interface 133 can better adapt to the connection requirements of external electrical connectors in different positions, and the connection is more flexible and convenient.

[0204] It can be understood that when the first interface 132 and the second interface 133 are arranged on different sides of the shell body 11, the first interface 132 and the second interface 133 also need to meet the requirements of electrical clearance and creepage distance, so that the first interface 132 and the second interface 133 cannot be electrically conductive.

[0205] In some embodiments, as shown in FIG. 3 and FIG. 10 to FIG. 12 , the first interface 132 and the second interface 133 are disposed at opposite ends of the housing body 11 .

[0206] It can be understood that the opposite ends of the shell body 11 refer to the two ends of the shell body 11 along the length direction (as shown by the arrow F2 in the figure).

[0207] In this way, the first interface 132 and the second interface 133 are arranged at two ends of the shell body 11 with a larger spacing distance, so that the first interface 132 and the second interface 133 have a larger spacing in space. On the one hand, it is beneficial to reduce the mutual interference between the first interface 132 and the second interface 133. On the other hand, it is also beneficial to optimize the layout of the first connecting member 124, the second connecting member 125 and the third connecting member 126 in the shell body 11, so that the internal structure of the first shell 101 is more orderly and compact.

[0208] In some embodiments, as shown in Figures 3 and 10 to 12, the shell body 11 is also provided with a first identification portion 14 and a second identification portion 15. The first identification portion 14 is provided on the side of the first interface 132, and the second identification portion 15 is provided on the side of the second interface 133. The first identification portion 14 and the second identification portion 15 have different identification contents.

[0209] Thus, a corresponding first identification portion 14 and a second identification portion 15 are respectively provided near the first interface 132 and the second interface 133 , and the two identification portions are provided with different identification information, so that the user can distinguish the first interface 132 and the second interface 133 by the corresponding identification information.

[0210] Exemplarily, each first connector 124 and second connector 125 corresponding to the first interface 132 is connected to the low-pressure control circuit, and the identification of the first identification part 14 can be "low-pressure control interface 13", and each third connector 126 corresponding to the second interface 133 is connected to the high-pressure sampling circuit, and the identification of the second identification part 15 can be "high-pressure sampling interface 13".

[0211] Another embodiment of the present application further provides a battery device 200, as shown in FIG2 , comprising a housing 20, a battery cell assembly 30, and the aforementioned high-voltage power distribution device 10. The battery cell assembly 30 and the high-voltage power distribution device 10 are all disposed within the housing 20. The high-voltage power distribution device 10 is electrically connected to the battery cell assembly 30 and is used to control the charging and discharging of the battery device 200.

[0212] Another embodiment of the present application further provides an electrical device, as shown in FIG1 , the electrical device includes the above-mentioned battery device 200 , and the battery device 200 is used to supply electrical energy to the electrical device.

[0213] The above description of the various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced with each other and will not be repeated herein for the sake of brevity.

[0214] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them.
