Technical Field

[0002] The present application relates to the technical field of electrical control equipment, and in particular to a power distribution device, a battery, and electrical equipment. Background Art

[0003] With the development of science and technology, more and more electrical equipment uses batteries as power sources, and the application of power distribution devices installed in electrical equipment is also increasing. Among them, power distribution devices can be used to distribute and manage the power supply of high-voltage systems in electrical equipment. Power distribution devices can also be used in batteries to control the charging and discharging of batteries. The electrical components in the power distribution device usually have an electrical connection structure for electrical connection with other electrical components. However, the electrical components in the power distribution device are compactly arranged, the spacing between the two electrical components is small, and the spacing between the electrical connection structures of the two electrical components is small. This results in poor insulation between the electrical connection structures of the two electrical components, affecting the reliability of the power distribution device.

[0004] The statements herein merely provide background information related to the present application and do not necessarily constitute prior art.

[0083] An electrical device may refer to a device that uses a battery as a power source, which provides electrical energy to the device, thereby driving the device. Electrical devices are typically equipped with a power distribution device, which is used to control the operation of the high-voltage circuits within the device. The "voltage" in a high-voltage circuit refers to voltage, and a high-voltage circuit refers to a circuit with a voltage exceeding 60V. For example, the power distribution device may be a high-voltage distribution box, which may be responsible for distributing and managing power to the high-voltage circuits within the device, such as a PDU (Power Distribution Unit) used in new energy vehicles. The PDU's function is to distribute and manage power within the high-voltage circuits of new energy vehicles, providing 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 for the entire vehicle, protecting and monitoring the operation of the high-voltage system. A high-voltage distribution box may also refer to a component used in a battery to control battery charging and discharging, such as a BDU (Battery Disconnect Unit). The BDU controls the battery's charging and discharging, and is a high-voltage distribution box designed specifically for batteries.

[0084] The arrangement of electrical components in the distribution device is becoming more and more compact to reduce the overall dimensions of the entire distribution device, thereby reducing the space occupied by electrical equipment and batteries, improving the structural compactness of the electrical equipment and reducing cost requirements; among them, the electrical components in the distribution device usually have an electrical connection structure for electrical connection with other electrical components, and the electrical components are compactly arranged, the distance between the two electrical components is small, the distance between the electrical connection structures of the two electrical components is small, and the insulation between the electrical connection structures of the two electrical components is poor, which makes it easy for the electrical connection structures of the two electrical components to short-circuit under high voltage conditions, seriously affecting the reliability of the distribution device.

[0085] In order to improve the insulation between the electrical connection structures of two electrical components in a distribution device, an embodiment of the present application provides a distribution device, which includes a first electrical component and a second electrical component, the first electrical component has a first electrical connection structure, the second electrical component has a second electrical connection structure, and the first electrical connection structure and the second electrical connection structure are arranged at intervals; and an insulating member is provided between the first electrical connection structure and the second electrical connection structure, and the insulating member can improve the insulation performance between the first electrical connection structure and the second electrical connection structure, thereby increasing the insulation between the electrical connection structures of the two electrical components, reducing the risk of short circuit, and helping to improve the reliability of the distribution device.

[0086] The power distribution device, battery and electrical equipment disclosed in the embodiments of the present application; from the perspective of the development of the market situation, the application of batteries is becoming more and more extensive. Batteries are not only used in energy storage power supply systems such as hydropower, thermal power, wind power and solar power stations, but are also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as in multiple fields such as military equipment and aerospace. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding. Electrical equipment can be but is not limited to mobile phones, tablets, laptops, electric toys, electric tools, battery cars, electric cars, ships, spacecraft, etc. Among them, electric toys can include fixed or mobile electric toys, for example, game consoles, electric car toys, electric ship toys and electric airplane toys, etc., and spacecraft can include airplanes, rockets, space shuttles and spacecraft, etc.

[0087] For the convenience of description, the following embodiments are described by taking a vehicle 1000 as an example of an electrical device according to an embodiment of the present application.

[0088] Please refer to Figure 1. Vehicle 1000 can be a fuel vehicle, a gas vehicle or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. A battery 1100 is provided inside the vehicle 1000. The battery 1100 can be provided at the bottom, head or tail of the vehicle 1000. The battery 1100 can be used to power the vehicle 1000. For example, the battery 1100 can serve as an operating power source for the vehicle 1000. The vehicle 1000 can also include a controller 1200 and a motor 1300. The controller 1200 is used to control the battery 1100 to power the motor 1300, for example, for starting, navigating and driving the vehicle 1000.

[0089] In some embodiments of the present application, the battery 1100 can serve not only as an operating power source for the vehicle 1000, but also as a driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0090] Referring to Figure 2 , an embodiment of a battery 1100 includes a housing 10 and battery cells 20, with the battery cells 20 housed within the housing 10. The housing 10 provides a storage space for the battery cells 20 and can have various structures. In some embodiments, the housing 10 can include a first portion 11 and a second portion 12, which overlap each other and together define a storage space for the battery cells 20. The second portion 12 can be a hollow structure with one end open, and the first portion 11 can be a plate-like structure, overlapping the open side of the second portion 12 to define the storage space. Alternatively, the first portion 11 and the second portion 12 can be hollow structures with one end open, with the open side of the first portion 11 overlapping the open side of the second portion 12. Of course, the housing 10 formed by the first portion 11 and the second portion 12 can have various shapes, such as a cylinder or a rectangular parallelepiped.

[0091] In the battery 1100 , there may be multiple battery cells 20 , and the multiple battery cells 20 may be connected in series, in parallel, or in mixed connection. Mixed connection means that the multiple battery cells 20 are connected in both series and in parallel.

[0092] In one embodiment, multiple battery cells 20 may be directly connected in series, parallel, or hybrid, and the entire battery cell 20 may then be housed within the housing 10. Alternatively, the battery 1100 may be constructed by first connecting multiple battery cells 20 in series, parallel, or hybrid to form a battery module, which is then connected in series, parallel, or hybrid to form a complete battery module, and then housed within the housing 10. The battery 1100 may also include other structures, such as a busbar assembly for electrically connecting the multiple battery cells 20.

[0093] Each battery cell 20 may be a secondary battery or a primary battery, and may also be a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited thereto. The battery cell 20 may be cylindrical, flat, rectangular, or in other shapes.

[0094] As another embodiment of the battery 1100 , the battery 1100 may not include the housing 10 , but may be assembled into an electrical device by electrically connecting a plurality of battery cells 20 and forming a whole with necessary fixing structures.

[0095] 3 and 4 , a battery cell 20 is the smallest unit of a battery. As shown in FIG3 , the battery cell 20 includes an end cap 21 , a housing 22 , an electrode assembly 23 , and other functional components.

[0096] The end cap 21 is a component that covers the opening of the housing 22 to isolate the internal environment of the battery cell 20 from the external environment. The shape of the end cap 21 can be adapted to the shape of the housing 22 to fit the housing 22. Optionally, the end cap 21 can be made of a material with a certain degree of hardness and strength (such as an aluminum alloy). This prevents the end cap 21 from deforming when subjected to compression or collision, thereby enhancing the structural strength and safety of the battery cell 20. Functional components such as electrode terminals 211 can be provided on the end cap 21. The electrode terminals 211 can be used to electrically connect to the electrode assembly 23 to output or input electrical energy to the battery cell 20. In some embodiments, the end cap 21 can also be provided with a pressure relief mechanism 212 for relieving internal pressure when the internal pressure or temperature of the battery cell 20 reaches a threshold. The end cap 21 can also be made of a variety of materials, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and this embodiment of the present application does not impose any specific limitations on this. In some embodiments, an insulating component may be provided inside the end cap 21 to isolate the electrical connection components in the housing 22 from the end cap 21 to reduce the risk of short circuit. For example, the insulating component may be made of plastic, rubber, or the like.

[0097] The housing 22 is a component that cooperates with the end cap 21 to form the internal environment of the battery cell 20. This internal environment can be used to accommodate the electrode assembly 23, electrolyte, and other components. The housing 22 and end cap 21 can be separate components. An opening can be provided in the housing 22, and the end cap 21 is placed over the opening to form the internal environment of the battery cell 20. Alternatively, the end cap 21 and housing 22 can be integrated. Specifically, the end cap 21 and housing 22 can form a common connection surface before other components are inserted into the housing. When the interior of the housing 22 needs to be enclosed, the end cap 21 is placed over the housing 22. The housing 22 can have a variety of shapes and sizes, such as a rectangular parallelepiped, a cylindrical shape, or a hexagonal prism. Specifically, the shape of the housing 22 can be determined based on the specific shape and size of the electrode assembly 23. The housing 22 can be made of a variety of materials, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and this embodiment of the present application does not impose any particular limitations on this.

[0098] The electrode assembly 23 is the component in the battery cell 20 where the electrochemical reaction occurs. One or more electrode assemblies 23 may be contained within the housing 22. The electrode assembly 23 includes a positive electrode member, a negative electrode member, and a separator. During the charge and discharge process of the battery cell, active ions (such as lithium ions) are embedded in and released from the positive and negative electrode members. The separator is provided between the positive and negative electrode members to prevent the positive and negative electrode members from short-circuiting while allowing active ions to pass through.

[0099] In some embodiments, the positive electrode member may be a positive electrode sheet, which may include a positive electrode current collector and a positive electrode active material disposed on at least one surface of the positive electrode current collector.

[0100] In some embodiments, the negative electrode member may be a negative electrode sheet, which may include a negative electrode current collector and a negative electrode active material disposed on at least one surface of the negative electrode current collector.

[0101] In some embodiments, the separator is a separator. The present application has no particular limitation on the type of separator, and any known separator with a porous structure having good chemical and mechanical stability can be selected.

[0102] In some embodiments, the electrode assembly 23 is a wound structure in which the positive electrode sheet and the negative electrode sheet are wound into a wound structure.

[0103] In some embodiments, the electrode assembly 23 is a laminated structure.

[0104] In some embodiments, the power distribution device 100 can be used to control the distribution and management of electrical energy from the battery 1100 to the controller 1200 and the motor 1300, thereby assisting the operation of the vehicle 1000; the power distribution device 100 can also be used to control the charging and discharging of the battery cells 20 in the battery 1100, wherein the power distribution device 100 can be installed inside the box 10 or outside the box 10.

[0105] In one embodiment of the present application, in combination with Figures 5 to 8, a distribution device 100 is provided, which includes a first electrical device 110 and a second electrical device 120, the first electrical device 110 has a first electrical connection structure 111; the second electrical device 120 has a second electrical connection structure 121, and the first electrical connection structure 111 and the second electrical connection structure 121 are arranged at intervals; wherein, an insulating member 130 is provided between the first electrical connection structure 111 and the second electrical connection structure 121.

[0106] The power distribution device 100 is typically equipped with multiple electrical components, which may include, but are not limited to, relays, fuses, resistors, current sensors, and other components. The first electrical component 110 may refer to a single electrical component in the power distribution device 100 or an electrical module integrating multiple electrical components in the power distribution device 100. The second electrical component 120 may refer to another electrical component or electrical module in the power distribution device 100 other than the first electrical component 110. Specifically, one of two adjacent electrical components in the power distribution device 100 is the first electrical component 110, and the other is the second electrical component 120.

[0107] The first electrical connection structure 111 may refer to an electrical connection structure that electrically connects the first electrical device 110 to other electrical devices. The other electrical devices herein may refer to the second electrical device 120, or may refer to electrical devices other than the first electrical device 110 and the second electrical device 120 in the power distribution device 100, or may refer to electrical devices outside the power distribution device 100. The first electrical connection structure 111 is made of a conductive material, such as copper, aluminum, or other conductive metal, to meet electrical conductivity requirements.

[0108] The second electrical connection structure 121 may refer to a connection structure extending from the second electrical device 120 to electrically connect to other electrical devices. The other electrical devices herein may refer to the first electrical device 110, or may refer to electrical devices other than the first electrical device 110 and the second electrical device 120 in the power distribution device 100, or may refer to electrical devices outside the power distribution device 100.

[0109] The insulating member 130 may refer to a component made of insulating material, and the insulating material may be, but is not limited to, insulating plastics such as PP (Polypropylene), PE (polyethylene), and PVC (Polyvinyl chloride).

[0110] The first electrical connection structure 111 and the second electrical connection structure 121 are spaced apart. It is understandable that a gap is formed between the first electrical connection structure 111 and the second electrical connection structure 121 so that the first electrical connection structure 111 and the second electrical connection structure 121 do not contact each other, thereby reducing the risk of short circuit.

[0111] An insulating member 130 is provided between the first electrical connection structure 111 and the second electrical connection structure 121. It can be understood that the insulating member 130 is located between the first electrical connection structure 111 and the second electrical connection structure 121, that is, the insulating member 130 is located in the gap formed between the first electrical connection structure 111 and the second electrical connection structure 121. The insulating member 130 can insulate and separate the first electrical connection structure 111 and the second electrical connection structure 121 to improve the insulation between the first electrical connection structure 111 and the second electrical connection structure 121.

[0112] In the power distribution device 100 of the embodiment of the present application, in the first electrical device 110 and the second electrical device 120, an insulating member 130 is provided between the first electrical connection structure 111 of the first electrical device 110 and the second electrical connection structure 121 of the second electrical device 120. The insulating member 130 insulates the first electrical connection structure 111 and the second electrical connection structure 121, thereby improving the insulation performance between the first electrical connection structure 111 and the second electrical connection structure 121, that is, improving the insulation between the electrical connection structures of the two electrical devices, reducing the risk of short circuit, and helping to improve the reliability of the power distribution device 100.

[0113] In another embodiment of the present application, as shown in FIG. 7 , an insulating member 130 is provided at a position where the first electrical connection structure 111 and the second electrical connection structure 121 are at the shortest distance.

[0114] When the spacing between the first electrical connection structure 111 and the second electrical connection structure 121 is the same at any position, the position at which the first electrical connection structure 111 and the second electrical connection structure 121 are at the shortest distance may refer to any position between the first electrical connection structure 111 and the second electrical connection structure 121; and when the spacing between the first electrical connection structure 111 and the second electrical connection structure 121 is different at different positions, the position at which the first electrical connection structure 111 and the second electrical connection structure 121 are at the shortest distance may refer to the position at which the spacing between the first electrical connection structure 111 and the second electrical connection structure 121 is the smallest.

[0115] By adopting the technical solution of this embodiment, the creepage distance between the first electrical connection structure 111 and the second electrical connection structure 121 is the smallest at the position with the shortest distance, that is, the insulation of the first electrical connection structure 111 and the second electrical connection structure 121 at the position with the shortest distance is poor, and the short circuit risk is high. The insulating part 130 is arranged at the position with the shortest distance between the first electrical connection structure 111 and the second electrical connection structure 121, which can effectively improve the insulation at this position, thereby effectively reducing the short circuit risk of the electrical connection structure of the two electrical devices, thereby effectively improving the reliability of the distribution device 100.

[0116] In another embodiment of the present application, as shown in FIG. 7 , the distance between the first electrical connection structure 111 and the second electrical connection structure 121 at the shortest position ranges from 3 mm to 9 mm.

[0117] The smaller the distance L between the first electrical connection structure 111 and the second electrical connection structure 121 at the shortest position, the more likely a short circuit will occur.

[0118] By adopting the technical solution of this embodiment, the distance L at the shortest position between the first electrical connection structure 111 and the second electrical connection structure 121 is within 3mm to 9mm, which is prone to short circuit.

In addition, a larger installation space can be provided for the insulating member 130 between the first electrical connection structure 111 and the second electrical connection structure 121, so that the insulating member 130 can be arranged larger, so that the insulating member 130 can better insulate and separate the first electrical connection structure 111 and the second electrical connection structure 121.

[0119] In another embodiment of the present application, as shown in FIG. 7 , the distance between the first electrical connection structure 111 and the second electrical connection structure 121 at the shortest position ranges from 3 mm to 6 mm.

[0120] By adopting the technical solution of this embodiment, the distance L at the shortest position between the first electrical connection structure 111 and the second electrical connection structure 121 is within 3mm to 6mm, which is more prone to short circuit. The insulating member 130 is arranged at the position with the shortest distance between the first electrical connection structure 111 and the second electrical connection structure 121, which can effectively improve the insulation between the first electrical connection structure 111 and the second electrical connection structure 121, thereby effectively reducing the risk of short circuit. In addition, a larger installation space can be provided for the insulating member 130 between the first electrical connection structure 111 and the second electrical connection structure 121, so that the insulating member 130 can be arranged larger, so that the insulating member 130 can better insulate and separate the first electrical connection structure 111 and the second electrical connection structure 121.

[0125] When the first electrical connection structure 111 and the second electrical connection structure 121 are located between the first terminal 1111 and the second terminal 1211 at the shortest distance, an insulating member 130 is provided between the first terminal 1111 and the second terminal 1211; it can be understood that the spacing between the first electrical connection member 1112 and the second electrical connection member 1212, the spacing between the first electrical connection member 1112 and the second terminal 1211, and the spacing between the first terminal 1111 and the second electrical connection member 1212 are all greater than the spacing between the first terminal 1111 and the second terminal 1211, that is, the spacing between the first terminal 1111 and the second terminal 1211 is equal to the minimum spacing between the first electrical connection structure 111 and the second electrical connection structure 121, and the insulating member 130 is located at the minimum spacing, which can effectively improve the insulation of the first electrical connection structure 111 and the second electrical connection structure 121, thereby effectively reducing the short circuit risk of the first electrical connection structure 111 and the second electrical connection structure 121, and improving the reliability of the distribution device 100.

[0126] When the first electrical connection structure 111 and the second electrical connection structure 121 are located between the first electrical connector 1112 and the second electrical connector 1212 at the shortest distance, an insulating member 130 is provided between the first electrical connector 1112 and the second electrical connector 1212; it can be understood that the spacing between the first terminal 1111 and the second terminal 1211, the spacing between the first electrical connector 1112 and the second terminal 1211, and the spacing between the first terminal 1111 and the second electrical connector 1212 are all greater than the spacing between the first electrical connector 1112 and the second electrical connector 1212, that is, the spacing between the first electrical connector 1112 and the second electrical connector 1212 is equal to the minimum spacing between the first electrical connection structure 111 and the second electrical connection structure 121, and the insulating member 130 is located at the minimum spacing, which can effectively improve the insulation of the first electrical connection structure 111 and the second electrical connection structure 121, thereby effectively reducing the short circuit risk of the first electrical connection structure 111 and the second electrical connection structure 121, and improving the reliability of the distribution device 100.

[0127] By adopting the technical solution of this embodiment, the insulating part 130 is arranged at the position where the distance between the first electrical connection structure 111 and the second electrical connection structure 121 is the shortest. This can effectively improve the insulation of the first electrical connection structure 111 and the second electrical connection structure 121, thereby effectively reducing the short circuit risk of the first electrical connection structure 111 and the second electrical connection structure 121, and improving the reliability of the distribution device 100.

[0128] In another embodiment of the present application, in combination with Figures 14 and 15, the first electrical connection structure 111 includes a first terminal 1111 and a first electrical connector 1112, and the first electrical connector 1112 is electrically connected to the first terminal 1111; the second electrical connection structure 121 includes a second terminal 1211 and a second electrical connector 1212, and the second electrical connector 1212 is electrically connected to the second terminal 1211; an insulating member 130 is provided between the first terminal 1111 and the second terminal 1211, and an insulating member 130 is provided between the first electrical connector 1112 and the second electrical connector 1212.

[0131] The relays in the power distribution device 100 are typically located in high-voltage circuits. Relays are electrical devices used to control the on / off state of circuits. Specifically, a relay includes components such as an electromagnet, a coil, and contacts. When the input quantity (such as voltage, current, or temperature) to the coil reaches a specified value, the electromagnet moves under the magnetic force of the coil, which in turn moves the contacts, thereby changing the on / off state of the controlled high-voltage circuit. The high-voltage circuits in which the relays reside have relatively high voltages, which increases the risk of short circuits in the electrical connections leading from the relays in the power distribution device 100.

[0132] The first relay 1101 may refer to a relay in the power distribution device 100, and the second relay 1201 may refer to another relay in the power distribution device 100; specifically, the first relay 1101 may refer to the main positive relay 1102, which is a relay in the main positive relay 1102 for controlling the on-off of the main positive circuit in the high-voltage circuit, and the second relay 1201 may refer to the main negative relay 1202, which is a relay in the main negative relay 1202 for controlling the on-off of the main negative circuit in the high-voltage circuit.

It is understood that, when the first electrical device 110 is the first relay 1101, the first terminal 1111 may refer to a connection terminal to which the contact of the first relay 1101 is electrically connected. This connection terminal is used to connect to a high-voltage circuit and control the on / off of the high-voltage circuit by opening and closing the contact. For example, the first terminal 1111 includes a first electrical connection portion 11111 and a first bolt 11112. The first electrical connection member 1112 is fixed to the first electrical connection portion 11111 by the first bolt 11112, thereby achieving electrical connection between the first terminal 1111 and the first electrical connection member 1112. The first electrical connection portion 11111 may refer to a conductive component extending from the contact of the first relay 1101. The first electrical connection portion 11111 and the first bolt 11112 may be made of a conductive material such as copper or aluminum.

[0134] The second terminal 1211 is a connection terminal extending from the contacts of the second relay 1201. It is understood that, if the second electrical device 120 is the second relay 1201, the second terminal 1211 may refer to a connection terminal to which the contacts of the second relay 1201 are electrically connected. This connection terminal is used to connect to a high-voltage circuit and control the on / off state of the high-voltage circuit by opening and closing the contacts. For example, the second terminal 1211 includes a second electrical connection portion 12111 and a second bolt 12112. The second electrical connection member 1212 is fixed to the second electrical connection portion 12111 via the second bolt 12112, thereby achieving electrical connection between the second terminal 1211 and the second electrical connection member 1212. The second electrical connection portion 12111 may refer to a conductive component extending from the contacts of the second relay 1201. The second electrical connection portion 12111 and the second bolt 12112 may be made of a conductive material such as copper or aluminum.

[0135] By adopting the technical solution of this embodiment, the insulating part 130 is arranged between the connection terminal led out from the contact of the first relay 1101 and the connection terminal led out from the contact of the second relay 1201 in the distribution device 100, which can reduce the short-circuit risk of the first relay 1101 and the second relay 1201 in the distribution device 100, thereby effectively reducing the short-circuit risk of the distribution device 100, which is conducive to improving the reliability of the distribution device 100.

[0136] In another embodiment of the present application, in combination with Figures 7 and 8, the power distribution device 100 also includes a mounting base 141, the mounting base 141 is constructed with a first accommodating cavity 1411 and a second accommodating cavity 1412, the first relay 1101 also includes a first switch unit 112, the first switch unit 112 is electrically connected to the first terminal 1111, and the first switch unit 112 is exposed in the first accommodating cavity 1411; the second relay 1201 includes a second switch unit 122, the second switch unit 122 is electrically connected to the second terminal 1211, and the second switch unit 122 is exposed in the second accommodating cavity 1412.

[0137] Mounting base 141 may be a mounting base for first relay 1101 and second relay 1201, serving as a support for first relay 1101 and second relay 1201. Mounting base 141 is typically made of an insulating material to provide insulation protection for electrical components within power distribution device 100. The insulating material may include, but is not limited to, insulating plastics such as PP (polypropylene), PE (polyethylene), and PVC (polyvinyl chloride). First relay 1101 may be connected to mounting base 141 by, but is not limited to, snap-fitting, clamping, screwing, bonding, or integral injection molding. Second relay 1201 may be connected to mounting base 141 by, but is not limited to, snap-fitting, clamping, screwing, bonding, or integral injection molding.

[0138] The first accommodating cavity 1411 may refer to the chamber of the mounting base 141 for accommodating the first relay 1101, and the second accommodating cavity 1412 may refer to the chamber of the mounting base 141 for accommodating the second relay 1201. The first switch unit 112 may refer to the main component within the first relay 1101 that performs on / off control, i.e., the unit consisting of the electromagnet, coil, and contacts within the first relay 1101 after removing the housing. The first terminal 1111 is electrically connected to the first switch unit 112, and the first switch unit 112 is electrically connected to the first electrical connector 1112 via the first terminal 1111, thereby achieving electrical connection between the first electrical device 110 and other electrical devices.

[0139] The first switch unit 112 is exposed in the first accommodating cavity 1411. It can be understood that the first switch unit 112 is not wrapped by a shell, but is directly exposed in the first accommodating cavity 1411, that is, the cavity wall of the first accommodating cavity 1411 can directly serve as the shell of the first relay 1101, that is, the first electrical device 110 is a relay after the shell is removed, and the mounting base 141 and the shell of the first relay 1101 are integrated to form an integrated structure, which is conducive to reducing production costs.
