[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 and a molding method of its shell structure, a battery device and an electrical equipment, so as 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, including a first housing, the first housing including:

[0009] a shell body, which is an insulating member; and

[0010] Multiple electrical connectors, each of which includes a main body and a first connecting portion extending from the main body, each main body being embedded in the interior of the shell body, and each first connecting portion being spaced apart and exposed on the surface of the shell body;

[0011] The plurality of electrical connectors are arranged at intervals and form an interval area between two adjacent main body parts. The surface of the shell body is recessed inward to form a plurality of recessed holes. At least part of the recessed holes is located in the interval area, and each interval area corresponds to at least one recessed hole.

[0012] By adopting the technical solution of the embodiment of the present application, the main body of the electrical connector is embedded in the interior of the shell body, and each main body is tightly combined with the shell body, so that the electrical connector can be firmly and stably fixed to the shell body. The electrical connector and the shell body, that is, the first shell, are disassembled and assembled with other structures as a whole, the assembly process is simplified, and the assembly efficiency is improved. On this basis, a number of concave hole structures are also provided on the shell body, part or all of the concave holes are located between the main bodies of two adjacent electrical connectors, and each spacing area is provided corresponding to at least one concave hole, so that the position between the two adjacent main bodies has a cavity area partially formed by the concave hole. Before injection molding the first shell, connecting ribs can be provided at the position of the spacing area corresponding to the concave hole to connect the two adjacent main bodies. After the injection molding is completed, the connecting ribs are disconnected at the position of the concave hole, thereby electrically separating the two adjacent main bodies. In this way, before and during the injection molding process, the two adjacent electrical connectors can be positioned and connected by providing connecting ribs. The ribs can play the role of positioning and supporting adjacent electrical connectors, so that multiple electrical connectors can be injection molded as a whole with the shell body. During the injection molding process, there will be no relative position movement between the electrical connectors, the setting position of the electrical connectors is more precise, and the risk of internal short circuit is reduced; after injection molding, the connecting ribs are disconnected from the recessed holes, and the connecting ribs between the two adjacent main body parts, that is, the two adjacent electrical connectors, are disconnected, so that insulation is achieved between the two electrical connectors. The electrical connector has a normal connection function and can establish connections with other electrical connection structures inside and outside the high-voltage distribution device, thereby improving the assembly efficiency of the high-voltage distribution device and providing guarantees for the stable operation of the high-voltage distribution device.

[0013] In some embodiments, the two main bodies are spaced apart along the first direction, and the two main bodies are respectively located on opposite sides of the corresponding concave hole along the first direction.

[0014] By adopting the technical solution of this embodiment, by arranging two adjacent main bodies close to the two opposite sides of the recessed hole, most or all of the connecting ribs pre-arranged between the two main body parts can face the recessed hole, so that all or most of the connecting ribs can be removed through the recessed hole, thereby maximizing the insulation distance between the two adjacent main body parts.

[0015] In some embodiments, at least three main bodies are sequentially arranged along the first direction, and the at least three sequentially arranged main bodies correspond to the same concave hole.

[0016] By adopting the technical solution of this embodiment, by setting the connecting ribs between three or more main parts corresponding to the same recessed hole, two or more connecting ribs can be disconnected at the same recessed hole position, which helps to simplify the molding steps and improve the molding efficiency of the first shell.

[0017] In some embodiments, along the first direction, a size of a portion of the main body portion located at a side of the recessed hole and protruding from the hole edge of the recessed hole is less than or equal to 1 mm.

[0018] By adopting the technical solution of this embodiment, the first direction is the width direction of the main body, and the main body located on the side of the recessed hole can be effectively blocked by the shell body. Only about 1 mm of the width of the main body is exposed in the internal space of the recessed hole, so that sufficient spacing space can be reserved between two adjacent main body parts to meet the requirements of electrical insulation.

[0019] In some embodiments, the shell body is provided with a plurality of recessed holes at intervals, and in all the interval regions, at least a portion of the interval regions correspond to the plurality of recessed holes along the extension direction of the corresponding main body portion.

[0020] By adopting the technical solution of this embodiment, for some main body parts with a longer length extension dimension, multiple connecting ribs can be arranged at intervals along the length extension direction to support the two main body parts, thereby helping to further reduce the risk of movement of the electrical connector and improve the position accuracy after molding.

[0021] In some embodiments, the spacing distance between the portions of two adjacent main body portions located inside the hole edge of the same recessed hole is greater than 3 mm.

[0022] By adopting the technical solution of this embodiment, when two adjacent electrical connectors are connected to a low-voltage circuit and the portion between the two adjacent main bodies located at the recessed hole is not separated by an insulating component, the spacing distance between the two adjacent main bodies located in the same recessed hole is greater than 3 mm, thereby making the electrical gap between the two adjacent main bodies greater than 3 mm, thereby meeting the insulation requirements.

[0023] In some embodiments, the spacing distance between the portions of two adjacent main body portions located inside the hole edge of the same recessed hole is greater than 9.5 mm.

[0024] By adopting the technical solution of this embodiment, when two adjacent electrical connectors are connected to a larger voltage circuit and the portion between the two adjacent main bodies located at the recessed hole is not separated by an insulating component, the spacing distance between the two adjacent main bodies located in the same recessed hole is greater than 9.5 mm, thereby making the electrical gap between the two adjacent main bodies greater than 9.5 mm, thereby meeting the insulation requirements.

[0025] In some embodiments, the spacing distance between the portions of two adjacent main body portions located inside the hole edge of the same recessed hole is greater than 19 mm.

[0026] By adopting the technical solution of this embodiment, when two adjacent electrical connectors are connected to a larger voltage circuit and the portion between the two adjacent main bodies located at the recessed hole is not separated by an insulating component, the spacing distance between the two adjacent main bodies located in the same recessed hole is greater than 19 mm, thereby making the electrical gap between the two adjacent main bodies greater than 19 mm, thereby meeting the insulation requirements.

[0027] In some embodiments, the shell body has a first surface and a second surface arranged opposite to each other, the main body is located between the first surface and the second surface, the recessed hole passes through the first surface and the second surface, and each spacing area passes through the first surface and the second surface through the corresponding recessed hole.

[0028] By adopting the technical solution of this embodiment, since the concave hole passes through the shell body, after the first shell is injection-molded and cooled, the connecting rib can be directly disconnected at the position of the through hole. When disconnecting the connecting rib, there is no need to consider the impact on the bottom part of the concave hole, and the molding process is simpler and more efficient.

[0029] In some embodiments, the high-voltage distribution device also includes a second shell connected to the first shell, some of the recessed holes are first holes, and the second shell is provided with at least one insulating protrusion corresponding to each first hole.

[0030] By adopting the technical solution of this embodiment, it also includes a second shell connected to the first shell, and the second shell is provided with insulating protrusions at the positions corresponding to each first hole. When the first shell is connected to the second shell, the insulating protrusions can be inserted into the first holes from the position between the two adjacent main bodies, thereby correspondingly separating the two adjacent main bodies, so that the two adjacent main bodies can be insulated by inserting the insulating protrusions between the two.

[0031] In some embodiments, the insulating protrusion extends from the second surface into the first hole along the direction from the second surface to the first surface, and the height of the protruding portion of the insulating protrusion relative to the second surface is greater than the height of the corresponding protruding portions of the two main bodies relative to the second surface.

[0032] By adopting the technical solution of this embodiment, the two adjacent main bodies are respectively arranged on both sides of the corresponding insulating protrusions. The current needs to pass through the corresponding insulating protrusions to reach the main body from one side, so that the two main bodies can be insulated from each other.

[0033] In some embodiments, an insulating protrusion is provided between two adjacent main body portions. Along the spacing direction between the two adjacent main body portions, the thickness of the insulating protrusion is L1, and the spacing distances between the insulating protrusion and the two adjacent main body portions are L2 and L3, respectively; along the direction from the second surface to the first surface, the heights of the protruding parts of the insulating protrusion relative to the two adjacent main body portions are L4 and L5, respectively; wherein the sum of L1, L2, L3, L4 and L5 is greater than 3 mm.

[0039] In some embodiments, the spacing distance between the insulating protrusion and the adjacent main body portion is greater than or equal to 1 mm.

[0040] By adopting the technical solution of this embodiment, there is a spacing distance of at least 1 mm between the insulating protrusion and the adjacent main body portion, so that the insulating protrusion can smoothly extend from the first hole without interfering with the corresponding main body portion.

[0041] In some embodiments, at least one of the two opposite side walls of the first hole is provided with a groove along a direction perpendicular to the spacing direction between two adjacent main body portions, and the insulating protrusion is snapped into the groove at a side portion corresponding to the groove.

[0042] By adopting the technical solution of this embodiment, at least one side of the insulating protrusion can be inserted into the groove of the corresponding hole wall of the first hole, and the insulating protrusion can be positioned by the groove, which helps to further improve the assembly accuracy.

[0043] In some embodiments, grooves are respectively provided on two opposite side walls of the first hole along a direction perpendicular to the spacing direction between two adjacent main body portions, and the opposite side portions of the insulating protrusion are respectively inserted into the corresponding grooves.

[0044] In some embodiments, along a direction perpendicular to the spacing direction between two adjacent main body portions, the width of the concave hole is 4 mm to 6 mm.

[0045] By adopting the technical solution of this embodiment, the width of the recessed hole is within the above-mentioned size range, so that the width of the recessed hole can accommodate a connecting rib with a certain width, and at the same time, a certain gap can be reserved between the connecting rib and the hole edge for the cutting tool to extend into to cut off the connecting rib, and the strength of the shell main body structure will not be reduced due to the recessed hole being too large.

[0046] In some embodiments, the shell body is also provided with an interface for adapting and plugging an external electrical connector. The interface has a cavity that passes through the surface of the shell body. Each electrical connector also includes a second connecting portion. The second connecting portion is exposed on the cavity wall and is located inside the cavity.

[0120] Currently, market developments indicate that power batteries are becoming increasingly widely used. They are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric vehicles, as well as in military equipment and aerospace. As power battery applications continue to expand, market demand is also growing.

[0121] As market demand for batteries continues to expand, higher demands are being placed on the manufacturing efficiency of battery devices. Typically, a battery device (Battery Apparatus) may include one or more battery cell assemblies to provide voltage and capacity, as well as a high-voltage power distribution device. This device is primarily responsible for controlling the smooth operation of the battery device's charging and discharging circuits, controlling the power-on and power-off processes, as well as the pre-charging and charging processes of the high-voltage electrical circuit. Among them, the "voltage" in the high-voltage distribution device refers to voltage, and the high-voltage distribution device refers to a distribution device used to control circuits with a voltage exceeding 60V; for example, the high-voltage distribution device can be a high-voltage distribution box, and the high-voltage distribution box can refer to a device responsible for the distribution and management of electric energy in the high-voltage system of electrical equipment, such as: PDU (Power Distribution Unit) used in new energy vehicles, wherein the function of PDU is to be responsible for the power distribution and management in the high-voltage system of new energy vehicles, and provide the whole vehicle with charging and discharging control, high-voltage component power-on control, circuit overload and short-circuit protection, high-voltage sampling, low-voltage control and other functions to protect and monitor the operation of the high-voltage system; the high-voltage distribution box can also refer to a component used in the battery and used to control the battery charging and discharging control, such as: BDU (Battery Disconnect Unit), BDU controls the battery charging and discharging, and is a high-voltage distribution box designed specifically for batteries.

[0122] The high-voltage power distribution device includes various electrical components, electrical connectors for realizing circuit connection and collecting various signals, and connectors for transmitting electrical signals. Among them, the various electrical connectors used for circuit connection and collecting various signals need to be accurately connected to the terminals, pins or interfaces of the corresponding electrical components to ensure the normal operation of the high-voltage power distribution device. Electrical connectors usually include copper busbars, aluminum busbars or conductive wire harnesses, etc. Many electrical connectors are dispersed in the shell of the high-voltage power distribution device. There are many electrical components inside the shell. When arranging each electrical connector, it is necessary to consider the insulation between adjacent electrical components and electrical connectors on the basis of ensuring stable electrical connection. The layout of electrical connectors inside the shell is complex, and it is difficult to realize automated connection and assembly. The overall assembly of the high-voltage power distribution device is difficult and the assembly efficiency is difficult to improve.

[0123] In the related art, in order to improve the assembly efficiency, a shell structure has emerged in which the electrical connector is partially embedded in the shell. The electrical connector is integrally formed with the shell using an insert injection molding process. After molding, the electrical connector and the shell are connected as a whole to other structures of the high-voltage distribution device to improve the assembly efficiency. However, although this shell structure can effectively improve the assembly efficiency, it is difficult to position the electrical connector during the injection molding process. The electrical connector is easily moved with the flow of the molten shell molding material, causing the electrical connector to shift in position and reducing the position accuracy of the electrical connector. Even adjacent electrical connectors may become electrically conductive due to movement, resulting in a greater risk of short circuit inside the high-voltage distribution device, affecting the stable operation of the high-voltage distribution device.

[0124] Based on this, an embodiment of the present application provides a high-voltage power distribution device, which embeds the main body of the electrical connector into the interior of the shell body, and each main body is tightly combined with the shell body, so that the electrical connector can be firmly and stably fixed to the shell body, and the electrical connector and the shell body, that is, the first shell, are disassembled and assembled with other structures as a whole, the assembly process is simplified, and the assembly efficiency is improved. On this basis, a number of concave hole structures are also provided on the shell body, and part or all of the concave holes are located between the main bodies of two adjacent electrical connectors, and each spacing area is provided corresponding to at least one concave hole, so that the position between the two adjacent main bodies has a cavity area partially formed by the concave hole. Before injection molding the first shell, connecting ribs can be provided at the position corresponding to the concave hole in the spacing area to connect the two adjacent main bodies. After the injection molding is completed, the connecting ribs are disconnected at the position of the concave hole, thereby electrically separating the two adjacent main bodies. In this way, before and during the injection molding process, the two adjacent electrical connectors can be positioned and connected by providing connecting ribs. The connecting ribs It can play the role of positioning and supporting adjacent electrical connectors, so that multiple electrical connectors can be injection molded as a whole with the shell body. During the injection molding process, there will be no relative position movement between the electrical connectors, the setting position of the electrical connector is more precise, and the risk of internal short circuit is reduced; after injection molding, the connecting ribs are disconnected from the concave holes, and the connecting ribs between the two adjacent main body parts, that is, the two adjacent electrical connectors, are disconnected, so that insulation is achieved between the two electrical connectors. The electrical connector has a normal connection function and can establish connections with other electrical connection structures inside and outside the high-voltage distribution device, thereby improving the assembly efficiency of the high-voltage distribution device and providing guarantees for the stable operation of the high-voltage distribution device.

[0125] The high-voltage power distribution device provided in the present application can be applied to a battery device, and the assembly efficiency and electrical reliability of the high-voltage power distribution device are improved, thereby helping to improve the overall assembly efficiency and electrical performance of the battery device, and improving the practicality and economy of the battery device.

[0140] In some embodiments, the housing 20 has a storage space 201 for accommodating the battery cell assembly 30.

[0144] The power distribution component device of the present application is described in detail below with reference to Figures 3 to 18 and specific embodiments. In the embodiments of the present application, the first direction is the direction indicated by the double-headed arrow F1 in the figures.

[0145] Please refer to Figures 3 to 5. An embodiment of the present application provides a high-voltage power distribution device 10, which includes a first shell 101. The first shell 101 includes a shell body 11 and a plurality of electrical connectors 12. The shell body 11 is an insulating member. Each electrical connector 12 includes a main body 121 and a first connection portion 122 extending from the main body 121. Each main body 121 is embedded in the interior of the shell body 11, and each first connection portion 122 is spaced apart from each other and exposed on the surface of the shell body 11; wherein, the plurality of electrical connectors 12 are spaced apart from each other and form a spacing area 1211 between two adjacent main bodies 121. The surface of the shell body 11 is recessed inward to form a plurality of recessed holes 111. At least part of the recessed holes 111 is located in the spacing area 1211, and each spacing area 1211 corresponds to at least one recessed hole 111.

[0146] 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.

[0147] In an 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 shell of the entire high-voltage power distribution device 10, or it can also be a part of the shell 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, so as 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 is composed of 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. The electrical connector 12 includes a main body 121. The main body 121 of each electrical connector 12 is embedded in the interior of the shell body 11, that is, the main body 121 does not protrude from the outer surface of the shell body 11, and most of its position is wrapped by the shell body 11. The main body 121 of each electrical connector 12 is positioned and embedded in the shell body 11. The main bodies 121 are spaced apart and isolated from each other, and can be insulated from each other.

[0148] On this basis, each electrical connector 12 also includes a first connecting portion 122, which is led out from the main body 121 and exposed on the outside of the surface of the shell body 11. The first connecting portion 122 is used to electrically connect to other electrical components 103 outside the first shell 101. Among them, the first connecting portion 122 can be electrically connected to other electrical components 103 through welding, crimping, plugging or locking. In this way, each electrical connector 12 is firmly positioned and connected to the shell body 11 through its own main body 121, so that it can be assembled and disassembled with the shell body 11 as an integral part with other structures. Each electrical connector 12 is then electrically connected to the electrical component 103 outside the first shell 101 through the exposed first connecting portion 122, so that each electrical connector 12 can normally perform its electrical connection function.

[0149] In an embodiment of the present application, a plurality of electrical connectors 12 are spaced apart from each other and form a spacing area 1211 between two adjacent main body portions 121, wherein the plurality of electrical connectors 12 are spaced apart from each other means that the main body portions 121 of each electrical connector 12 are spaced apart from each other, and the first connection portions 122 of each electrical connection are spaced apart from each other, that is, the electrical connectors 12 do not contact each other, and there is a spacing area 1211 between the main body portions 121 of two adjacent electrical connectors 12, and the spacing area 1211 can be partially or completely filled with the material of the shell body 11, so that the two adjacent main body portions 121 can be electrically separated by the partial structure and spatial spacing of the insulating shell body 11 in the spacing area 1211, and the first connection portions 122 of each electrical connector 12 are spaced apart from each other and are not conductive to each other, thereby insulating the electrical connectors 12 from each other.

[0150] Please refer to Figures 16 and 17 together. In the embodiment of the present application, the surface of the shell body 11 is also recessed inward to form a plurality of recessed holes 111, wherein the recessed holes 111 can be a groove 1112 structure formed by a downward recess of one side surface of the shell body 11 but not passing through the entire shell body 11, or the recessed holes 111 can also be a through hole structure formed by a downward recess of one side surface of the shell body 11 and passing through the other opposite surface, that is, the recessed holes 111 pass through the entire shell body 11. At least part of the recessed hole 111 is located in the spacing area 1211, that is, part of the recessed hole 111 or the entire recessed hole 111 is arranged in the spacing area 1211 between the two adjacent main body parts 121, so that the spacing area 1211 between the two adjacent main body parts 121 can form at least a partial cavity area by means of the recessed hole 111, that is, there is an area between the two adjacent main body parts 121 that is not filled by the shell body 11; and each spacing area 1211 corresponds to at least one recessed hole 111, that is, there is one or more areas that are not filled by the shell body 11 formed by the recessed hole 111 at the position between the two adjacent main body parts 121. In this way, before multiple electrical connectors 12 are integrally injection-molded with the shell body 11, connecting ribs 126 can be set to connect two adjacent main body parts 121. The setting position of the connecting ribs 126 corresponds to a partial position of at least one recessed hole 111 on the shell body 11. After the first shell 101 is formed, part or all of the connecting ribs 126 between the two adjacent main body parts 121 corresponds to a recessed hole 111. In this way, after the first shell 101 is cooled and formed, the connecting ribs 126 are disconnected at the position of the recessed hole 111, so that the two adjacent main body parts 121 can be electrically separated.

[0151] Among them, each spacing area 1211 corresponds to at least one recessed hole 111, which means that there is a cavity area formed by the recessed hole 111 in the spacing area 1211 between the two adjacent main bodies 121, so that the two main bodies 121 can be provided with connecting ribs 126 at positions corresponding to the cavity areas, and the corresponding connecting ribs 126 are disconnected at the recessed holes 111 after the first shell 101 is formed, thereby electrically separating the corresponding two main bodies 121; or, it can be that the spacing area 1211 between the two connected main bodies 121 is provided with multiple cavity areas formed by multiple recessed holes 111, and the multiple cavity areas are spaced apart from each other, so that the two main bodies 121 can be provided with connecting ribs 126 at positions corresponding to each cavity area, that is, multiple connecting ribs 126 are arranged at intervals along the length extension direction of the main body 121 to connect the two adjacent main bodies 121, and the corresponding connecting ribs 126 are disconnected at each recessed hole 111 after the first shell 101 is formed, thereby electrically separating the corresponding two main bodies 121.

After the injection molding is completed, the connecting rib 126 is disconnected at the position of the recessed hole 111, thereby electrically separating the two adjacent main bodies 121. In this way, before and during the injection molding process, the two adjacent electrical connectors 12 can be connected by providing the connecting rib 126. 26 positioning connection, the connecting rib 126 can play the role of positioning and supporting adjacent electrical connectors 12, so that multiple electrical connectors 12 can be injection molded as a whole with the shell body 11. During the injection molding process, there will be no relative position movement between the electrical connectors 12, the setting position of the electrical connector 12 is more precise, and the risk of internal short circuit is reduced; after injection molding, the connecting rib 126 is disconnected from the recessed hole 111, and the connecting rib 126 between the two adjacent main body parts 121, that is, the two adjacent electrical connectors 12, is disconnected, so that insulation is achieved between the two electrical connectors 12, and the electrical connector 12 has a normal connection function and can establish a connection with other electrical connection structures inside and outside the high-voltage distribution device 10, thereby improving the assembly efficiency of the high-voltage distribution device 10 and providing a guarantee for the stable operation of the high-voltage distribution device 10.

[0156] In some embodiments, as shown in FIG. 3 , FIG. 5 and FIG. 7 , the two main bodies 121 are spaced apart along the first direction, and the two main bodies are respectively located on opposite sides of the corresponding recessed hole 111 along the first direction.

[0157] In this embodiment, the two main bodies 121 are arranged at intervals along the first direction, that is, the main bodies 121 of the two electrical connectors 12 are arranged at intervals along the first direction, and part of the shell body 11 is embedded between the two main bodies 121. For a shell body 11 with a thinner thickness, the first direction can be the width direction, length direction or other non-thickness direction of the shell body 11, and for a shell body 11 with a certain thickness, the first direction can be any direction of the width, length, thickness, etc. of the shell body 11. The two main bodies 121 are respectively located on opposite sides of the corresponding recessed hole 111 along the first direction, that is, the spacing area 1211 between the two adjacent main bodies 121 corresponds to one recessed hole 111, and the middle area of ​​the spacing area 1211 is arranged opposite to the middle of the recessed hole 111, so that along the first direction, that is, along the spacing direction of the two main bodies 121, one main body 121 is located at one side of the recessed hole 111, and the other adjacent main body 121 is located at the other side opposite to the recessed hole 111. In this way, a connecting rib 126 can be set between the two main bodies 121 at the position corresponding to the recessed hole 111. After the first shell 101 is injection molded and cooled, the connecting rib 126 is disconnected from the corresponding two side positions of the recessed hole 111, thereby completely removing the part of the connecting rib 126 facing the recessed hole 111.

[0158] Among them, it can be understood that the main body 121 is located at the side part of the recessed hole 111, and the main body 121 can be partially exposed in the internal space of the recessed hole 111, or the main body 121 can be completely blocked by the shell body 11, and only the connecting rib 126 is retained to extend from the edge of the recessed hole 111 to the internal space of the recessed hole 111.

[0159] In this way, by arranging two adjacent main bodies close to the two opposite sides of the recessed hole 111, most or all of the connecting ribs 126 pre-arranged between the two main body parts 121 can face the recessed hole 111, so that all or most of the connecting ribs 126 can be removed through the recessed hole 111 to maximize the insulation distance between the two adjacent main body parts 121.

[0160] In some embodiments, as shown in FIG. 3 , FIG. 5 and FIG. 8 , at least three main body portions 121 are sequentially arranged along the first direction, and the at least three sequentially arranged main body portions 121 correspond to the same concave hole 111 .

[0161] In this embodiment, the recessed hole 111 has a certain length along the first direction, so that the same recessed hole 111 can correspond to three or more main body portions 121. That is, among the three or more main body portions 121, portions of the spacing regions 1211 between each two adjacent main body portions 121 are respectively opposite and connected to the same recessed hole 111. For example, the three main body portions 121 are arranged in sequence along the first direction, forming two spacing regions 1211 between the three main body portions 121. Each of the two spacing regions 1211 has at least a portion opposite the same recessed hole 111, so that a partial cavity structure is formed in each of the two spacing regions 1211 through the same recessed hole 111, and the connecting rib 126 connecting the two adjacent main body portions 121 can be exposed and disconnected through the same recessed hole 111.

[0162] In this way, by arranging the connecting ribs 126 between three or more main bodies 121 corresponding to the same recessed hole 111 , two or more connecting ribs 126 can be disconnected at the same recessed hole 111 position, thereby helping to simplify the molding steps and improve the molding efficiency of the first shell 101 .

[0163] In some embodiments, as shown in FIG3 , FIG7 and FIG8 , along the first direction, a dimension a1 of a portion of the main body 121 located at a side of the recessed hole 111 protruding from the hole edge of the recessed hole 111 is less than or equal to 1 mm.

[0164] In this way, the first direction is the width direction of the main body 121, and the main body 121 located on the side of the recessed hole 111 can be effectively blocked by the shell body 11. Only about 1 mm of the width of the main body 121 is exposed in the internal space of the recessed hole 111, so that sufficient spacing space can be reserved between two adjacent main body parts 121 to meet the requirements of electrical insulation.

[0165] In some embodiments, the shell body 11 is provided with a plurality of recessed holes 111 at intervals, and among all the spacing regions 1211 , at least a portion of the spacing regions 1211 correspond to the plurality of recessed holes 111 along the extension direction of the corresponding main body portion 121 .

[0166] Among them, “all the spacing areas 1211” include all the spacing areas 1211 located between the main bodies 121 of the electrical connectors 12, and “a portion of the spacing areas 1211 in all the spacing areas 1211” refers to one spacing area 1211 or two spacing areas 1211 or three or more spacing areas 1211 in all the plurality of spacing areas 1211, and “at least a portion of the spacing areas 1211 in all the spacing areas 1211 correspond to the plurality of recessed holes 111 along the extension direction of the corresponding main body 121” refers to all the plurality of spacing areas One spacing area 1211 or two spacing areas 1211 or three spacing areas 1211 or all spacing areas 1211 in 1211, in one, two, three or all spacing areas 1211, each spacing area 1211 corresponds to the multiple recessed holes 111 arranged at intervals along the extension direction of the corresponding main body 121, that is, multiple spaced cavity areas are formed between two adjacent main bodies 121 by means of the multiple spaced recessed holes 111, so that a connecting rib 126 can be respectively arranged at the position corresponding to the multiple recessed holes 111 to connect the two main bodies 121.

[0167] In this way, for some main body parts 121 with a longer length extension dimension, multiple connecting ribs 126 can be arranged at intervals along the length extension direction to support the two main body parts 121, thereby helping to further reduce the risk of movement of the electrical connector 12 and improve the position accuracy after molding.

[0168] In some embodiments, there needs to be a certain distance between the portions of two adjacent main bodies 121 located inside the edge of the same recessed hole 111 to meet insulation requirements.

[0169] It is understandable that, because the interior space of the recessed hole 111 is exposed to the insulated main body 121, the space within the recessed hole 111 is connected to the outside air environment. Therefore, the main body 121 located within the interior space of the recessed hole 111 will be in contact with the air, thereby requiring a certain electrical spacing between adjacent main bodies 121 exposed within the same recessed hole 111 to reduce the risk of electrical conduction between two adjacent main bodies 121 at the recessed hole 111. The inner side of the hole edge refers to the internal space enclosed and defined by the edge of the recessed hole 111, that is, the inside of the recessed hole 111.

[0170] In some embodiments, as shown in FIG. 3 , FIG. 7 and FIG. 8 , the spacing distance a2 between the portions of two adjacent main body portions 121 located inside the hole edge of the same recessed hole 111 is greater than 3 mm.

[0171] In a specific embodiment, when two adjacent electrical connectors 12 are connected to a low-voltage circuit and the portion between the two adjacent main bodies 121 located at the recessed hole 111 is not separated by an insulating component, the spacing distance between the two adjacent main bodies 121 located in the same recessed hole 111 is greater than 3 mm, thereby making the electrical gap between the two adjacent main bodies 121 greater than 3 mm to meet the insulation requirements.

[0172] For example, the spacing distance between two adjacent main body portions 121 may be 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, etc.

[0173] In some embodiments, the spacing between the portions of two adjacent main body portions 121 located inside the edge of the same recessed hole 111 is greater than 9.5 mm.

[0174] In a specific embodiment, when two adjacent electrical connectors 12 are connected to a larger voltage loop and the portion between the two adjacent main bodies 121 located at the recessed hole 111 is not separated by an insulating component, the spacing distance between the two adjacent main bodies 121 located in the same recessed hole 111 is greater than 9.5 mm, thereby making the electrical gap between the two adjacent main bodies 121 greater than 9.5 mm to meet the insulation requirements.

[0175] 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, and the part between the two adjacent main bodies 121 located at the recessed hole 111 is not separated by an insulating component, the spacing distance between the two adjacent main bodies 121 can be 9.6mm, 10mm, 10.5mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm or 18mm, etc.

[0176] In some embodiments, the distance between the portions of two adjacent main body portions 121 located inside the edge of the same recessed hole 111 is greater than 19 mm.

[0177] In a specific embodiment, when two adjacent electrical connectors 12 are connected to a larger voltage loop and the portion between the two adjacent main bodies 121 located at the recessed hole 111 is not separated by an insulating component, the spacing distance between the two adjacent main bodies 121 located in the same recessed hole 111 is greater than 19 mm, thereby making the electrical gap between the two adjacent main bodies 121 greater than 19 mm to meet the insulation requirements.

[0178] For example, when two adjacent electrical connectors 12 are connected to a circuit with a voltage greater than 660V, and the portion between the two adjacent main body portions 121 located at the recessed hole 111 is not separated by an insulating component, the spacing distance between the two adjacent main body portions 121 can be a larger size such as 19.1mm, 19.5mm, 19.8mm, 20mm, 20.5mm, 21mm, 21.5mm, 22mm, 22.5mm or 23mm.

[0179] In other embodiments, as shown in Figures 3, 4, 11 and 12, the shell body 11 has a first surface 112 and a second surface 113 arranged opposite to each other, the main body 121 is located between the first surface 112 and the second surface 113, the recessed hole 111 passes through the first surface 112 and the second surface 113, and each spacing area 1211 passes through the first surface 112 and the second surface 113 through the corresponding recessed hole 111.

[0180] Among them, the first surface 112 and the second surface 113 can be two surfaces of the shell body 11 along the thickness direction, the main body 121 of each electrical connector 12 is located between the first surface 112 and the second surface 113, and the recessed hole 111 passes through the first surface 112 and the second surface 113 of the shell body 11, that is, the recessed hole 111 is a through hole passing through the shell body 11, and correspondingly, the spacing area 1211 between the two adjacent main bodies 121 also passes through the shell body 11 through the corresponding recessed hole 111.

[0181] In this way, since the recessed hole 111 passes through the shell body 11, after the first shell 101 is injection molded and cooled, the connecting rib 126 can be directly disconnected at the through-hole position. When disconnecting the connecting rib 126, there is no need to consider the impact on the bottom part of the recessed hole 111, and the molding process is simpler and more efficient.

[0182] In some embodiments, as shown in Figures 3, 4, 11 and 12, the high-voltage power distribution device 10 also includes a second shell 102 connected to the first shell 101, some of the recessed holes 111 are first holes 1111, and the second shell 102 is provided with at least one insulating protrusion 1021 corresponding to each first hole 1111. The insulating protrusion 1021 is inserted into the first hole 1111 at a position between two adjacent main body portions 121, and at least one insulating protrusion 1021 is provided between two adjacent main body portions 121 corresponding to the same first hole 1111.

[0183] In this embodiment, a plurality of recessed holes 111 are provided on the shell body 11, wherein a portion of the recessed holes 111 are first holes 1111, and another portion of the recessed holes 111 are non-first holes 1111. The high-voltage power distribution device 10 further includes a second shell 102 connected to the first shell 101. The second shell 102 is provided with insulating protrusions 1021 at positions corresponding to the first holes 1111. When the first shell 101 and the second shell 102 are connected, the insulating protrusions 1021 can be inserted into the first holes 1111 from a position between two adjacent main bodies 121, thereby separating the two adjacent main bodies 121, so that the two adjacent main bodies 121 can be insulated by the insulating protrusions 1021 inserted therebetween.

[0184] Moreover, in a specific embodiment, at least one insulating protrusion 1021 is provided between two adjacent main body portions 121 corresponding to the same first hole 1111, that is, there can be one insulating protrusion 1021 between two adjacent main body portions 121 located in the same first hole 1111, that is, the two adjacent main body portions 121 are insulated by one insulating protrusion 1021, or, there can also be multiple insulating protrusions 1021 between two adjacent main body portions 121 located in the same first hole 1111, and multiple insulating protrusions 1021 are arranged in sequence along the spacing direction between the two adjacent main body portions 121, that is, the two adjacent main body portions 121 are insulated by multiple stacked insulating protrusions 1021.

[0185] In some embodiments, as shown in Figures 3, 4, 11 and 12, the insulating protrusion 1021 extends from the second surface 113 into the first hole 1111 along the direction pointing from the second surface 113 to the first surface 112, and the height of the protruding portion of the insulating protrusion 1021 relative to the second surface 113 is greater than the height of the protruding portions of the corresponding two main body portions 121 relative to the second surface 113.

[0186] Among them, the direction along the second surface 113 pointing to the first surface 112 is the axial direction of the recessed hole 111, that is, the thickness direction of the shell body 11. The second shell body 102 is provided with an insulating protrusion 1021 protruding from the lower space of the second surface 113 away from the first surface 112. Each insulating protrusion 1021 extends from the second surface 113 into the corresponding first hole 1111, and the height of the protruding part of the insulating protrusion 1021 relative to the second surface 113 is greater than the height of the protruding part of the corresponding two main body parts 121 relative to the second surface 113, so that the two adjacent main body parts are respectively arranged on both sides of the corresponding insulating protrusion 1021. The current needs to climb over the corresponding insulating protrusion 1021 to reach the main body part 121 on the other side from the main body part 121 on one side, thereby achieving insulation.

[0187] In a specific embodiment, as shown in Figure 12, an insulating protrusion 1021 is provided between two adjacent main body portions 121. Along the spacing direction between the two adjacent main body portions 121, the thickness of the insulating protrusion 1021 is L1, and the spacing distances between the insulating protrusion 1021 and the two adjacent main body portions 121 are L2 and L3 respectively; along the direction from the second surface 113 to the first surface 112, the heights of the protruding portions of the insulating protrusion 1021 relative to the two adjacent main body portions 121 are L4 and L5 respectively; wherein the sum of L1, L2, L3, L4 and L5 is greater than 3 mm.

[0188] In this embodiment, when an insulating protrusion 1021 is provided between two adjacent main body portions 121, the creepage distance between the two adjacent main body portions 121 includes: a thickness dimension L1 of the insulating protrusion 1021, a distance dimension L2 of the interval between one main body portion 121 and the insulating protrusion 1021, a distance dimension L3 of the interval between the other main body portion 121 and the insulating protrusion 1021, a height dimension L4 of the protruding portion of the insulating protrusion 1021 relative to one main body portion 121 along the direction from the second surface 113 to the first surface 112, and a height dimension L5 of the protruding portion of the insulating protrusion 1021 relative to the other main body portion 121 along the direction from the second surface 113 to the first surface 112. If the sum of the five dimensions is greater than 3 mm, the creepage distance between the two adjacent main body portions 121 separated by the insulating protrusion 1021 can meet the requirement of being greater than 3 mm.

[0189] In a specific embodiment, when two adjacent electrical connectors 12 are connected to a low-voltage circuit, the creepage distance between two adjacent main bodies 121 located in the same recess 111 is greater than 3 mm to meet insulation requirements.

[0190] For example, the creepage distance between two adjacent main body portions 121 may be 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, etc.

[0191] 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 main body portions 121 is greater than 9.5 mm.

[0192] Thus, when two adjacent electrical connectors 12 are connected to a circuit with a higher voltage, the creepage distance between two adjacent main bodies 121 in the same recess 111 is greater than 9.5 mm, thereby meeting insulation requirements.

[0193] 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 main body parts 121 can be 9.6mm, 10mm, 10.5mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm or 18mm, etc.

[0194] 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 main body portions 121 is greater than 9.5 mm.

[0195] Thus, when two adjacent electrical connectors 12 are connected to a larger voltage loop, the creepage distance between two adjacent main bodies 121 located in the same recess 111 is greater than 19 mm, thereby meeting insulation requirements.

[0196] 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 main body parts 121 can be a larger size such as 19.1mm, 19.5mm, 19.8mm, 20mm, 20.5mm, 21mm, 21.5mm, 22mm, 22.5mm or 23mm.

[0197] In some embodiments, the spacing between the insulating protrusion 1021 and the adjacent main body portion 121 is greater than or equal to 1 mm. That is, there is at least 1 mm between the insulating protrusion 1021 and the adjacent main body portion 121, so that the insulating protrusion 1021 can smoothly extend from the first hole 1111 without interfering with the corresponding main body portion 121.

[0198] In a specific embodiment, the spacing distance between the insulating protrusion 1021 and the adjacent main body portion 121 can be 1 mm, 1.2 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.8 mm, 1.9 mm or 2.0 mm.

[0199] In some embodiments, as shown in Figures 3, 8 and 10, grooves 1112 are respectively provided on the opposite side walls of the first hole 1111 along a direction perpendicular to the spacing direction between the two adjacent main body portions 121, and the opposite side portions of the insulating protrusion 1021 are respectively inserted into the corresponding grooves 1112.

[0200] In this embodiment, along a direction perpendicular to the spacing direction between the two adjacent main body portions 121, that is, along the width direction of the insulating protrusion 1021, at least one side of the insulating protrusion 1021 can be inserted into the groove 1112 of the hole wall of the corresponding first hole 1111, and the insulating protrusion 1021 can be positioned by the groove 1112, thereby helping to further improve the assembly accuracy.

[0201] In a specific embodiment, grooves 1112 are respectively formed on two opposite side walls of the first hole 1111 along a direction perpendicular to the spacing direction between two adjacent main body portions 121 , and the opposite side portions of the insulating protrusion 1021 are respectively inserted into the corresponding grooves 1112 .

[0202] That is, along the width direction of the insulating protrusion 1021 , two side portions of the insulating protrusion 1021 are respectively inserted into the grooves 1112 on the two side walls of the recessed hole 111 .

[0203] In some embodiments, as shown in FIG. 7 and FIG. 8 , along a direction perpendicular to the spacing direction between two adjacent main body portions 121 , a width B1 of the concave hole 111 is 4 mm to 6 mm.

[0204] In this embodiment, along the direction perpendicular to the spacing direction between the two adjacent main body portions 121, that is, along the width direction of the recessed hole 111, the width dimension of the recessed hole 111 is within the above-mentioned dimension range, so that the width of the recessed hole 111 can accommodate the connecting rib 126 with a certain width, and at the same time, a certain gap can be reserved between the connecting rib 126 and the hole edge for the cutting tool to extend into to cut off the connecting rib 126, and the structural strength of the shell body 11 will not be reduced due to the recessed hole 111 being too large.

[0205] In a specific embodiment, the width of the recessed hole 111 may be 4 mm, 4.2 mm, 4.4 mm, 4.5 mm, 4.8 mm, 5 mm, 5.2 mm, 5.5 mm, 5.8 mm or 6 mm.

[0206] It can be understood that in the above embodiments, the shape of the concave hole 111 can be a regular shape such as a rectangle, a circle, a polygon, etc., or it can be other irregular shapes. This application does not limit the shape of the concave hole 111, and a suitable shape can be selected as needed during design.

[0207] In some embodiments, as shown in Figures 3 to 5 and 13, the shell body 11 is also provided with an interface 13 for adapting and plugging an external electrical connector. The interface 13 has a cavity 131 that passes through the surface of the shell body 11. Each electrical connector 12 also includes a second connecting portion 123. The second connecting portion 123 is exposed on the cavity wall of the cavity 131 and is located inside the cavity 131. The second connecting portion 123 is used to electrically connect to the electrical connector plugged into the interface 13.

[0208] In this embodiment, as shown in Figures 5, 6, 9 and 13, each electrical connector 12 also includes a second connecting portion 123, which is used to electrically connect to an external electrical connector of the high-voltage distribution device 10. In this way, an interface 13 adapted to the external electrical connector is provided on the first shell 101, and the electrical connector can be adapted to be inserted into the interface 13, and the second connecting portion 123 of each electrical connector 12 is introduced into the internal cavity 131 of the interface 13, and each second connecting portion 123 is exposed on the cavity wall surface of the cavity 131 of the interface 13. When the external electrical connector is inserted into the interface 13, the connecting terminal in the electrical connector is electrically contacted with the corresponding second connecting portion 123, so that each electrical connector 12 is connected to the external circuit through the corresponding electrical connector.

[0209] In this way, the second connection part 123 of each electrical connector 12 for connecting to the external circuit is led out to one or more interfaces 13, and an electrical connection is established by plugging the interface 13 with the external electrical connector. Each second connection part 123 is accommodated in the cavity 131 of the interface 13 and does not need to protrude beyond the surface of the shell body 11, thereby effectively reducing the risk of interference between the second connection part 123 and other adjacent components. In addition, there is no need to lead the second connection part 123 out through an adapter or a wire, which helps to simplify the internal structure of the high-voltage distribution device 10 and improve assembly efficiency.

[0210] In some embodiments, as shown in FIG. 5 , FIG. 6 , FIG. 9 and FIG. 13 , the second connection portion 123 is protruded from the cavity wall of the cavity 131 and is disposed toward the opening of the cavity 131 .

[0211] In this embodiment, the second connecting 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 adapted and 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.

[0212] In some embodiments, as shown in Figures 5, 6, 9 and 13, part of the electrical connector 12 is the first connector 124, and the other part of the electrical connector 12 is the second connector 125. The interface 13 includes a first interface 132 and a second interface 133 that are spaced apart. The second connection portion 123 of each first connector 124 is located in the cavity 131 of the first interface 132, and the second connection portion 123 of each second connector 125 is located in the cavity 131 of the second interface 133.

[0213] In this embodiment, the first shell 101 is provided with a first interface 132 and a second interface 133, wherein the electrical connector 12 includes at least one first connector 124 and at least one second connector 125, the second connection portion 123 of each first connector 124 corresponds to the cavity 131 located at the first interface 132, and the second connection portion 123 of each second connector 125 corresponds to the cavity 131 located at the second interface 133, so that the first connector 132 and the second interface 133 are respectively connected to the corresponding external connectors, and the first connector 124 and the second connector 125 are respectively connected to the corresponding circuits. In this way, different electrical connectors 12 can be distinguished and isolated in space, which helps to reduce the risk of electrical interference or connection confusion.

[0214] Among them, it can be understood that the first connector 124 and the second connector 125 can be divided according to different usage functions, and correspondingly, the first interface 132 and the second interface 133 with different functions are set on the first shell 101. Alternatively, the first connector 124 and the second connector 125 can be divided according to different connection objects, and correspondingly, the first interface 132 and the second interface 133 connected to different connectors are set on the first shell 101. Alternatively, the first connector 124 and the second connector 125 can be divided according to different electrical characteristics, and correspondingly, the first interface 132 and the second interface 133 with different electrical characteristics are set on the first shell 101. For example, the first connector 124 can be responsible for connecting to the connector on the high-voltage power supply side, and the second connector 125 can be a connector for connecting to the load.

[0215] In some embodiments, the first interface 132 and the second interface 133 are disposed on the same side of the housing body 11 .

[0216] 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 the external electrical connector on the same side of the high-voltage distribution device 10. This facilitates centralized connection with the external electrical connector, which is beneficial to simplifying the layout of the external connection lines, reducing line crossing and confusion, and improving the regularity and reliability of the connection.

[0217] 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.

[0218] In some other embodiments, different from the above embodiment, the shell body 11 has a plurality of different sides, and the first interface 132 and the second interface 133 are disposed on different sides of the shell body 11 .

[0219] 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.

[0220] 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.

[0221] In a specific embodiment, the first connection portion 122 of each first connection member 124 is connected to a low-voltage circuit within the high-voltage power distribution device 10. For example, the first connection portion 122 is connected to a control terminal of a conduction coil of an electromagnetic relay, such as a control terminal of a main positive relay, a control terminal of a main negative relay, or a control terminal of a pre-charge relay.

[0222] In a specific embodiment, the first connection portion 122 of each second connection member 125 is connected to a high-voltage circuit in the high-voltage power distribution device 10. For example, the first connection portion 122 is connected to a high-voltage sampling copper busbar in the high-voltage power distribution device 10, for example, a high-voltage busbar connected to the output end of a battery cell group, or a high-voltage busbar connected to the input end of a battery cell group, or a high-voltage busbar connected to a high-voltage contact of a relay, etc.

[0223] In a specific embodiment, in the first interface 132 , the electrical gap between two adjacent second connection portions 123 is greater than 3 mm to meet electrical safety requirements.

[0224] For example, in the first interface 132, the electrical gap between two adjacent second connection parts 123 can be 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, etc., or, when the second connection part 123 is connected to the high-voltage circuit, the electrical gap between two adjacent second connection parts 123 can be 9.5mm, 10mm, 11mm, or even a larger size.

[0225] Alternatively, in other embodiments, an insulating separator 16 may be provided between two adjacent second connection portions 123 in the first interface 132 for separation, and the creepage distance between the two adjacent second connection portions 123 may be greater than 3 mm to meet electrical safety requirements.

[0226] It can be understood that in this embodiment, within the first interface 132, the two adjacent second connection parts 123 are protruded from the cavity wall of the cavity 131 of the first interface 132, and the insulating partition 16 is also protruded at the position between the two second connection parts 123, and the protruding height of the insulating partition 16 is higher than the protruding height of the two second connection parts 123, so that the current between the two second connection parts 123 needs to crawl through the insulating partition 16 to be conducted. On this basis, the creepage distance between the two adjacent second connection parts 123 is designed to be greater than 3 mm to meet the electrical safety requirements between the two second connection parts 123.

[0227] For example, in the first interface 132, the creepage distance between two adjacent second connection parts 123 can be 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, etc., or, when the second connection part 123 is connected to the high-voltage circuit, the creepage distance between two adjacent second connection parts 123 can be 9.5mm, 10mm, 11mm, or even a larger size.

[0228] In a specific embodiment, in the second interface 133 , the electrical gap between two adjacent second connection portions 123 is greater than 3 mm to meet electrical safety requirements.

[0229] For example, in the second interface 133, the electrical gap between two adjacent second connection parts 123 can be 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, etc., or, when the second connection part 123 is connected to the high-voltage circuit, the electrical gap between two adjacent second connection parts 123 can be 9.5mm, 10mm, 11mm, or even a larger size.

[0230] Alternatively, in other embodiments, an insulating separator 16 may be provided between two adjacent second connection portions 123 in the second interface 133 for separation, and the creepage distance between the two adjacent second connection portions 123 may be greater than 3 mm to meet electrical safety requirements.

[0231] It can be understood that in this embodiment, in the second interface 133, the two adjacent second connection parts 123 are protruded from the cavity wall of the cavity 131 of the first interface 132, and the insulating partition 16 is also protruded at the position between the two second connection parts 123, and the protruding height of the insulating partition 16 is higher than the protruding height of the two second connection parts 123, so that the current between the two second connection parts 123 needs to crawl through the insulating partition 16 to be conducted. On this basis, the creepage distance between the two adjacent second connection parts 123 is designed to be greater than 3 mm to meet the electrical safety requirements between the two second connection parts 123.

[0232] For example, in the second interface 133, the creepage distance between two adjacent second connection parts 123 can be 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, etc., or, when the second connection part 123 is connected to the high-voltage circuit, the creepage distance between two adjacent second connection parts 123 can be 9.5mm, 10mm, 11mm, or even a larger size.

[0233] In a specific embodiment, the creepage distance between the first interface 132 and the second interface 133 is greater than 3 mm to meet electrical safety requirements.

[0234] It can be understood that in this embodiment, the first connection part 122 is accommodated in the internal space of the first interface 132, and the second connection part 123 is accommodated in the internal space of the second interface 133. In this way, in terms of space, the first interface 132 and the second interface 133 are isolated from each other by each other's side walls, so that the current between a first connection part 122 closest to the second interface 133 in the first interface 132 and a second connection part 123 closest to the first interface 132 in the second interface 133 needs to crawl over the side walls between the two interfaces 13 to be conducted. On this basis, the creepage distance between the first interface 132 and the second interface 133 is designed to be greater than 3 mm to meet the electrical safety requirements between the first interface 132 and the second interface 133.

[0235] Exemplarily, the creepage distance between the first interface 132 and the second interface 133 can be 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, etc., or, when the first connection part 122 and the second connection part 123 are connected to the high-voltage circuit, the creepage distance between the first interface 132 and the second interface 133 can be 9.5 mm, 10 mm, 11 mm, or even a larger size.

[0236] In this way, in each embodiment, the electrical clearance or creepage distance between the two connected second connection parts 123 located in the first interface 132 or the second interface 133 meets the electrical safety requirements, and the electrical clearance or creepage distance between the first interface 132 and the second interface 133 meets the electrical safety requirements.

[0237] In some embodiments, as shown in Figures 3, 5 and 13, 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 identifications.

[0238] 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.

[0239] For example, when each electrical connector 12 corresponding to the first interface 132 is connected to a low-voltage control circuit, the identification of the first identification portion 14 may be "low-voltage control interface", and when each electrical connector 12 corresponding to the second interface 133 is connected to a high-voltage sampling circuit, the identification of the second identification portion 15 may be "high-voltage sampling interface".

[0240] In some embodiments, the distance between two adjacent main body portions 121 is 5 mm to 25 mm.

[0241] By setting the spacing distance between two adjacent main bodies 121 within the above-mentioned range, on the one hand, the internal space of the shell body 11 can be reasonably utilized to arrange the main bodies 121 of each electrical connector 12, so that each main body 121 can have a reasonable layout position. On the other hand, the spacing distance between two adjacent main bodies 121 can also meet the electrical safety requirements and reduce the risk of electrical failure due to excessive voltage.

[0242] Exemplarily, the spacing distance between two adjacent main body portions 121 may be 5 mm, 7 mm, 10 mm, 12 mm, 14 mm, 15 mm, 16 mm, 18 mm, 20 mm, 22 mm, 24 mm or 25 mm, etc.

[0243] It can be understood that the greater the voltage passing through two adjacent main bodies 121 , the greater the spacing distance that needs to be reserved between the two main bodies 121 .

[0244] In some embodiments, along a direction perpendicular to the extension direction of the electrical connector 12 , the width of the electrical connector 12 is 0.5 mm to 10 mm.

[0245] Setting the width of the electrical connector 12 within the above range can, on the one hand, ensure that the electrical connector 12 has a certain structural strength, and on the other hand, ensure that the width of each electrical connector 12 can meet electrical safety requirements.

[0246] For example, the width of each electrical connector 12 may be 0.5 mm, 1.0 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm.

[0247] It can be understood that the greater the voltage at the corresponding access point of each electrical connector 12 is, the greater the width of the electrical connector 12 is.

[0248] In some embodiments, along the recessed direction of the recessed hole 111 , the thickness of the electrical connector 12 is 0.5 mm to 2.5 mm.

[0249] Setting the thickness of the electrical connector 12 within the above range can, on the one hand, ensure that the electrical connector 12 has a certain structural strength, and on the other hand, ensure that the thickness of each electrical connector 12 can meet electrical safety requirements.

[0250] For example, the thickness of the phase electrical connector 12 may be 0.5 mm, 0.6 mm, 0.8 mm, 1.0 mm, 1.2 mm, 1.5 mm, 1.8 mm, 2.0 mm, 2.2 mm, 2.4 mm or 2.5 mm.

[0251] Please refer to Figure 14 and Figures 16 to 18. Other embodiments of the present application also provide a method for forming the shell structure of a high-voltage power distribution device, which is used to manufacture the shell structure of the high-voltage power distribution device provided in the above embodiments, wherein the shell structure can be the first shell 101 in the above embodiments.

[0252] In some embodiments, a method for forming a shell structure of the high-voltage power distribution device 10 includes the following steps:

[0253] S10, manufacturing a plurality of electrical connectors 12, wherein each electrical connector 12 includes a main body 121, and the main bodies 121 of two adjacent electrical connectors 12 are spaced apart and connected by a connecting rib 126;

[0254] S20, integrally embedding the main body 121 of each electrical connector 12 into the same shell body 11 by injection molding, and reserving a recessed hole 111 at a position of the shell body 11 facing the connecting rib 126;

[0255] S30 , disconnecting the corresponding connecting ribs 126 at the position of the concave hole 111 to obtain a shell structure.

[0256] In step S10, based on the electrical design requirements of the high-voltage power distribution device 10, a plurality of electrical connectors 12 are made of suitable conductive materials (such as copper, aluminum, or other metals with excellent conductivity). As shown in FIG16 , each electrical connector 12 has a main body 121, and the main bodies 121 of two adjacent electrical connectors 12 are spaced apart and connected by connecting ribs 126. The function of the connecting ribs 126 is to facilitate the unified operation and positioning of the plurality of electrical connectors 12 during the early manufacturing process, ensuring that the relative positions of the components are accurate. For example, during the mold processing process, the connecting ribs 126 can enable a group of electrical connectors 12 to be handled and installed as a whole, thereby improving production efficiency.

[0257] It is understandable that in a specific embodiment, the electrical connector 12 can be manufactured by forging, stamping, or die forming. The main bodies 121 of two adjacent electrical connectors 12 are spaced apart and connected by connecting ribs 126, which means that connecting ribs 126 are provided at one or more locations between the two adjacent main bodies 121 for connection.

[0258] In step S20, a material with excellent insulating properties is selected to make an injection mold for the shell body 11. The mold has reserved embedding positions for the main body 121 of each electrical connector 12, which match the shape and size of the main body 121 of the electrical connector 12. During the injection molding process, the main body 121 of each electrical connector 12 is accurately placed in the corresponding position of the mold, and then the molten insulating material is injected into the mold cavity. The injection pressure is used to fully wrap the insulating material around the main body 121 of the electrical connector 12, achieving integrated injection molding and embedding. This integrated molding method not only simplifies the assembly process, but also greatly enhances the connection strength between the electrical connector 12 and the shell body 11. At the same time, a recessed hole 111 is reserved at the position of the shell body 11 facing each connecting rib 126, and at least part of the recessed hole 111 is located in the spacing area 1211 between the two adjacent main body parts 121, that is, part of the recessed hole 111 or the entire recessed hole 111 is arranged in the spacing area 1211 between the two adjacent main body parts 121, so that the connecting rib 126 between the two adjacent main body parts 121 can be exposed l through the recessed hole 111, as shown in Figures 17 and 18.

[0259] In step S30, after the integral injection molding is completed and the recessed hole 111 is reserved, the corresponding connecting ribs 126 are disconnected at the location of the recessed hole 111. For example, the connecting ribs 126 can be disconnected by punching or laser cutting, so that the main bodies 121 of two adjacent electrical connectors 12 that were originally connected together by the connecting ribs 126 are disconnected, thereby achieving electrical isolation between them within the shell body 11.

[0260] In some examples, the first shell 101 can be manufactured as follows: according to the design requirements, the electrical connector 12 is made of a material with good conductivity such as copper or aluminum, and the electrical connector 12 having a main body 121 and a connecting rib 126 is made by stamping, forging, cutting and other processes, wherein the connecting rib 126 is set at one or more positions between two adjacent main bodies 121 for connection; according to the design requirements, a suitable insulating material is selected to make a mold for the shell body 11, and when designing the mold, the embedding positions of the main bodies 121 of multiple electrical connectors 12 are accurately reserved, and the size and shape are precisely matched with the size and shape of the main body 121 of the electrical connector 12, so that each main body 121 can be embedded in the shell body 11 after being embedded. To achieve a tight connection, at the same time, one or more hole positions are reserved. The position of the recessed hole 111 corresponds to the position of the connecting rib 126 between the main body 121 of the electrical connector 12. Then, the main body 121 of the electrical connector 12 is accurately placed in the corresponding position of the mold for forming the shell body 11. Then, the molten insulating material is injected into the mold. Through the one-piece injection molding process, the shell body 11 and the main body 121 of the electrical connector 12 are firmly combined together, and recessed holes 111 are formed at the positions of each connecting rib 126. Finally, punching, laser cutting and other processes are used to disconnect the corresponding connecting rib 126 at the position of each recessed hole 111, so that the two connected main bodies 121 are electrically separated to obtain a shell structure.

[0261] In the molding method of the shell structure of this embodiment, before and during injection molding, two adjacent electrical connectors 12 are positioned and connected by setting connecting ribs 126. The connecting ribs 126 can play a role in positioning and supporting the adjacent electrical connectors 12, so that the multiple electrical connectors 12 can be integrally injection-molded with the shell body 11 as a whole. During the injection molding process, the relative positions of the electrical connectors 12 will not move, thereby simplifying the positioning operation of the electrical connectors 12 during the injection molding process. The setting position of the electrical connector 12 can be more accurately placed in the preset position of the mold. In addition, during the injection molding process, the risk of the electrical connector 12 moving with the flow of the injection molding material can be reduced, and the position of the electrical connector 12 after molding is more precise; and, after the injection molding is cooled, the connecting rib 126 is disconnected from the recessed hole 111, and the connecting rib 126 between the two adjacent main body parts 121, that is, the two adjacent electrical connectors 12, is disconnected, so that insulation is achieved between the two electrical connectors 12, and the electrical connector 12 has a normal connection function and can establish connections with other electrical connection structures inside and outside the high-voltage distribution device 10, providing a guarantee for improving the assembly efficiency of the high-voltage distribution device 10.

[0262] Please refer to Figure 15 and Figures 16 to 18. Other embodiments of the present application also provide another method for forming the shell structure of the high-voltage distribution device 10, which is used to manufacture the shell structure of the high-voltage distribution device 10 provided in the above embodiments, wherein the shell structure can be the assembly structure of the first shell 101 and the second shell 102 in the above embodiments.

[0263] In a specific embodiment, a method for forming a shell structure of the high-voltage power distribution device 10 includes the following steps:

[0264] S10, manufacturing a plurality of electrical connectors 12, wherein each electrical connector 12 includes a main body 121, and the main bodies 121 of two adjacent electrical connectors 12 are spaced apart and connected by a connecting rib 126;

[0265] S20, integrally embedding the main body 121 of each electrical connector 12 into the same shell body 11 by injection molding, and reserving a recessed hole 111 at a position of the shell body 11 facing the connecting rib 126;

[0266] S301, disconnecting the corresponding connecting rib 126 at the position of the concave hole 111 to obtain the first shell 101;

[0267] S40, manufacturing a second housing 102 having a plurality of insulating protrusions 1021 protruding from its surface, wherein the size of the insulating protrusions 1021 is adapted to the size of at least part of the recessed holes 111;

[0268] S50 , connecting the first shell 101 and the second shell 102 , and inserting the insulating protrusion 1021 into the matching recess 111 between two adjacent main body portions 121 to obtain a shell structure.

[0269] Different from the above-mentioned embodiment, in the embodiment of the present application, the shell structure includes a first shell 101 and a second shell 102. The first shell 101 is obtained after disconnecting the corresponding connecting rib 126 at the position of the recessed hole 111. On this basis, the second shell 102 is made, wherein the surface of the second shell 102 is protruding with an insulating protrusion 1021, and the insulating protrusion 1021 is adapted to part of the recessed hole 111 on the first shell 101, so that after the first shell 101 and the second shell 102 are connected, the insulating protrusion 1021 can be inserted into the corresponding recessed hole 111, and the main body parts of the two adjacent electrical connectors 12 corresponding to the recessed hole 111 are separated, so that the two adjacent main body parts 121 can be insulated by inserting the insulating protrusion 1021 between the two.

[0270] In step S40, a material with good insulation properties is selected to make an injection mold for the second shell 102, wherein a cavity for forming an insulating protrusion 1021 is designed in the mold, and the shape and size of the cavity are based on meeting the insulation requirements between the two main body parts 121 to be separated and being able to be adapted to be inserted into the corresponding recessed hole 111.

[0271] In the above embodiment, as shown in FIG. 17 and FIG. 18 , the step of manufacturing a plurality of electrical connectors 12 further includes providing a pre-cut portion 1261 on each connecting rib 126 , wherein the pre-cut portion 1261 includes at least one of a thickness-reduced portion and a width-reduced portion.

[0272] When making the electrical connector 12, after forming the main body 121 and the connecting ribs 126, the connecting ribs 126 are processed and a pre-cut portion 1261 is provided on each connecting rib 126. The thickness of the pre-cut portion 1261 is smaller than the thickness at other positions of the connecting rib 126, or the width of the pre-cut portion 1261 is smaller than the width at other positions of the connecting rib 126, so that the connecting rib 126 can be disconnected more conveniently and quickly in preparation for the subsequent disconnection.

[0273] It should be noted that, in this embodiment, the thickness-reduced portion refers to a portion of the connecting rib 126 where the thickness is reduced compared to the original normal thickness of the connecting rib 126. For example, the original thickness of the connecting rib 126 is 1 mm, and at the set pre-cut portion 1261, the thickness is reduced to 0.5 mm through a certain processing technology (such as grinding, milling, etc.), forming a relatively thin area. The width-reduced portion refers to a portion of the connecting rib 126 where the width is reduced compared to the original normal width of the connecting rib 126, that is, the width of the connecting rib 126 in a specific area is narrowed. For example, the original width of the connecting rib 126 is 3 mm, and at the pre-cut portion 1261, the width is reduced by 1 mm through cutting, stamping, etc., forming a relatively narrow portion.

[0274] In a specific embodiment, as shown in Figures 17 and 18, in the step of providing a pre-cut portion 1261 on each connecting rib 126, a pre-cut groove 1262 is provided on at least one side of the end portion where the connecting rib 126 is connected to the corresponding main body portion 121 to form the pre-cut portion 1261.

[0275] In this embodiment, the pre-cut portion 1261 on the connecting rib 126 corresponds to a groove 1112 structure arranged on the side of the connecting rib 126. In this way, by setting a pre-cut groove 1262 on the side of the end portion where the connecting rib 126 is connected to the main body 121, the width of the connecting rib 126 at the connection position with the main body 121 is narrowed, thereby facilitating disconnection of the connecting rib 126 from the position where the pre-cut groove 1262 is located in subsequent steps.

[0276] Among them, a pre-cut groove 1262 can be set on one side of the end where the connecting rib 126 is connected to the corresponding main body 121, or pre-cut grooves 1262 can be set on both sides of the end where the connecting rib 126 is connected to the corresponding main body 121.

[0277] It is understandable that the pre-cut groove 1262 can be an arc-shaped groove, or a rectangular groove, or other irregular notch structures.

[0278] In some embodiments, along a direction perpendicular to the spacing direction between two adjacent main body portions 121 , a width B2 of the connecting rib 126 is 1 mm to 3 mm.

[0279] The width of the connecting rib 126 is set within the above-mentioned range, so that the connecting rib 126 can play the role of connecting and positioning adjacent main body parts 121. At the same time, the width of the connecting rib 126 is not too large, so as to reduce the difficulty of disconnection processing. At the same time, it is not necessary to set an overly large recessed hole 111 at the corresponding position of the shell body 11 of the first shell 101 due to the setting of the connecting rib 126 with an excessively large width, thereby affecting the structural strength of the shell body 11.

[0280] In a specific embodiment, the width of the connecting rib 126 is 1 mm, 1.2 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.8 mm, 2.0 mm, 2.2 mm, 2.5 mm, 2.8 mm or 3 mm.

[0281] In some embodiments, the thickness of at least a portion of the connecting rib 126 is smaller than the thickness of the main body 121 .

[0282] The thickness of the connecting rib 126 is set to be smaller than that of the main body 121, so that the connecting rib 126 can not only connect and position adjacent main bodies 121, but also be not too thick to reduce the difficulty of disconnection processing.

[0283] In a specific embodiment, the thickness of the connecting rib 126 is 0.2 mm to 1.0 mm.

[0284] The thickness of the connecting rib 126 is set within the above range, so that the connecting rib 126 can not only connect and position the adjacent main body parts 121, but also the thickness of the connecting rib 126 is not too large to reduce the difficulty of the disconnection process.

[0285] In a specific embodiment, the thickness of the connecting rib 126 is 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm or 1.0 mm, etc.

[0286] In some embodiments, along the spacing direction between two adjacent main body portions 121 , the length of the connecting rib 126 is 5 mm to 25 mm.

[0287] The length of the connecting rib 126 is set within the above range, so that the separation distance between adjacent main bodies 121 can be controlled by designing the length of the connecting rib 126, thereby ensuring that the main bodies 121 of adjacent electrical connectors 12 have a suitable spacing size.

[0288] In a specific embodiment, the length of the connecting rib 126 is 5 mm, 10 mm, 15 mm, 16 mm, 18 mm, 20 mm, 22 mm, 24 mm or 25 mm.

[0289] 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.

[0290] 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.

[0291] 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.

[0292] 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. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein.
