Description

Connectors, batteries and electrical devices

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on October 31, 2023, with application number 202322933075.2 and invention name “Connector, Battery and Electrical Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application belongs to the field of battery technology, and more specifically, relates to a connector, a battery, and an electrical device. Background Art

[0003] The statements here only provide background information related to the present application and do not necessarily constitute prior art. In the related art, the battery includes a casing and a plurality of battery cells installed in the casing. During the charging and discharging process of the battery, the battery cells will release a large amount of heat, which can easily cause the temperature inside the battery to be too high and burn. Usually, a heat exchange plate is used to cool the battery cells, but the low temperature of the heat exchange plate can easily cause condensation of water vapor in the casing, corrode the circuit or cause a short circuit, affecting the safety of the battery. In order to prevent fire or condensation of water vapor, a pipe connector will be installed on the casing, and connected to the gas source through the pipe connector to deliver dry gas or fire extinguishing agent to the casing. This will increase the complexity of the casing, resulting in a large number of connectors on the casing, cumbersome connections, and inconvenient operation.

[0004] Summary of the Invention

[0005] The purpose of the embodiments of the present application is to provide a connector to solve the technical problem of a large number of battery box connectors in the prior art.

[0006] In a first aspect, the present application provides a connector, comprising:

[0007] a base having a plug-in side and a fixed side disposed opposite the plug-in side; and

[0008] A first terminal, the first terminal is connected to the base, the first terminal is located on the plug side and is used to be electrically connected to the power supply;

[0009] The base is also provided with a flow channel for conveying fluid, and the two ports of the flow channel are respectively located on the plug-in side and the fixed side.

[0010] The base allows for connection to an external plug-in module and electrical connection to a power source via a first terminal, thereby completing the circuit. The flow channel allows for communication with the interior of the housing, facilitating the delivery of fluids such as dry gas or fire extinguishing agents. When dry gas is delivered to the housing, moisture inside the housing is blown out, drying the interior and preventing moisture accumulation, thereby improving battery safety. When fire extinguishing agents are delivered to the housing, combustion within the battery is prevented, rapidly extinguishing the fire. When the connector is connected, both the circuit and the piping are connected simultaneously, reducing the number of connectors, simplifying the housing structure, and streamlining the connection process for easier operation.

[0011] In one embodiment, the connector further includes a valve plug for controlling the on-off of the flow channel, and the valve plug is installed in the flow channel.

[0012] By adopting the above technical means, the on-off of the flow channel in the connector can be controlled so as to block the flow channel when air supply is not required.

[0013] In one embodiment, the flow channel includes a sliding hole section and a limiting hole section that are interconnected. The limiting hole section is arranged at the end of the sliding hole section away from the fixed side. The cross-sectional area of ​​the limiting hole section is smaller than the cross-sectional area of ​​the sliding hole section. One end of the valve plug is inserted into the limiting hole section to seal the limiting hole section, and the other end of the valve plug is slidably engaged with the inner wall of the sliding hole section.

[0014] By adopting the above technical means, the fluid can be cut off when the valve plug slides to the limiting hole section, thereby closing the flow channel and preventing the valve plug from sliding out from the end of the flow channel close to the plug-in side.

[0015] In one embodiment, the valve plug includes a sliding section and a plug head section. The sliding section is in sliding engagement with the inner wall of the sliding hole section, and the plug head section is plugged into the limiting hole section.

[0016] By adopting the above-mentioned technical means, the valve plug can be made to slide along the sliding hole section. When the valve plug slides toward the limiting hole section, it drives the plug head section to be inserted into the limiting hole section, thereby blocking the fluid; when the valve plug moves away from the limiting hole section, it drives the plug head section to be separated from the limiting hole section, thereby releasing the fluid, thereby controlling the connection or disconnection of the flow channel by pushing the valve plug to slide.

[0017] In one embodiment, the flow channel further includes a flared section connecting the limiting hole section and the sliding hole section, and the cross-sectional area of ​​the flared section gradually increases from the limiting hole section toward the sliding hole section.

[0021] In one embodiment, a first air hole for communicating with the flaring section is opened on the guide section, a second air hole communicating with the first air hole and the sliding section is opened on the sliding section, and the second air hole passes through one end of the sliding section facing away from the flaring section.

[0022] By adopting the above technical means, when the valve plug leaves the limiting hole section, the first air hole and the second air hole can communicate with the limiting hole section and the sliding hole section, so that the flow channel is unobstructed.

[0023] In one embodiment, the connector further includes an elastic member and a limiting member, the limiting member is installed at one end of the sliding hole section away from the limiting hole section, one end of the elastic member is abutted and connected to the valve plug, and the other end of the elastic member is abutted and connected to the limiting member.

[0024] By adopting the above technical means, the elastic member and the valve plug can be restricted from sliding out from the end of the sliding hole section away from the limiting hole section, and the elastic member can push the valve plug toward the limiting hole section to achieve automatic closing of the flow channel.

[0025] In one embodiment, the elastic member is a spring; and / or the limiting member is a snap ring.

[0026] By adopting the above technical means, the spring can push the valve plug to slide, so that the plug head section can be inserted into the limiting hole section; the retaining ring can stop the spring to prevent the spring from sliding out of the end of the sliding hole away from the limiting hole.

[0027] In one embodiment, a first sealing ring is sleeved on the plug head section.

[0028] By adopting the above technical means, the sealing effect between the plug head section and the inner wall of the limiting hole section can be enhanced when the plug head section is inserted into the limiting hole section.

[0031] In one embodiment, the connector includes an air guide column provided on the plugging side, and a vent hole communicating with the flow channel is provided in the air guide column.

[0032] By adopting the above technical means, when the air guide column is inserted into the external flow channel, it can be connected with the external flow channel so that the fluid can flow in the external flow channel and the air guide column.

[0033] In one embodiment, a notch groove communicating with the vent hole is formed at one end of the air guide column away from the base, and the notch groove passes through the outer peripheral wall of the air guide column.

[0034] By adopting the above technical means, the fluid can flow from the side of the air guide column, avoiding blocking of the fluid when the end of the air guide column abuts against the plane.

[0035] In one embodiment, the air guide column includes a plug-in section connected to the base and an abutment column provided at one end of the plug-in section away from the base, and the cross-sectional area of ​​the abutment column is smaller than the cross-sectional area of ​​the plug-in section.

[0080] Currently, market developments indicate that batteries are increasingly being 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 cars, as well as in military equipment and aerospace. As battery applications continue to expand, market demand is also growing.

[0081] In related technologies, a battery includes a casing and multiple battery cells. During the charge and discharge process of the battery, the battery cells will generate a large amount of heat, which will increase the pressure and temperature inside the casing, and may easily cause the casing to explode or catch fire. In order to prevent the pressure inside the casing from being too high, exhaust holes will be set on the casing to release the pressure inside the casing. In order to reduce the temperature of the battery, a heat exchange plate is usually used to cool the battery cells. In the process of using a heat exchange plate to cool the battery cells, the temperature of the heat exchange plate is low, which may easily cause moisture inside the casing to condense and form water vapor. The water vapor will corrode the circuit and may even cause a short circuit, affecting the service life and safety of the battery.

[0082] To this end, a pipe connector can be installed on the box body. Dry gas can be delivered into the box body through an air source to blow out the water vapor and dry the box body. Fire extinguishing agent can also be delivered into the box body through the pipe connector to extinguish the fire. Installing a pipe connector on the box body increases the complexity of the box structure and the number of assembly steps. The pipe connector and the power connector need to be connected each time the battery is charged or discharged. This is not only cumbersome but also easy to miss or remove external pipes, which is very inconvenient.

[0083] Based on the above considerations, some embodiments of the present application provide a connector, as shown in Figures 3, 4, and 8. The connector 10 includes a base 11 and a first terminal 16. The base 11 has a plug-in side 101 and a fixed side 102. A flow channel 110 is provided in the base 11 for conveying fluid. The openings of the flow channel 110 are located on the plug-in side 101 and the fixed side 102, respectively. The first terminal 16 is used to electrically connect to a power source. By using the connector 10, when plugged into an external plug-in module, the first terminal 16 can connect to the power circuit and simultaneously achieve pipeline connectivity, so as to facilitate the delivery of dry gas into the battery housing 40 during charging and discharging to ensure the dryness of the housing 40. This reduces the number of plug-in times, helps simplify operation, and can prevent forgetting to unplug the gas pipe when plugging in and out of the power supply, making operation more convenient.

[0084] The connector disclosed in the embodiment of the present application can be an electrical device for using a battery or a battery pack, and the connector can be used for charging and discharging connections of the battery or battery pack. The electrical device can be, but is not limited to, a vehicle, a portable device, a laptop computer, a ship, a spacecraft, an electric toy, an electric tool, and the like. The vehicle can be a fuel vehicle, a gas vehicle, or a new energy vehicle, and the new energy vehicle can be a pure electric vehicle, a hybrid vehicle, or an extended-range vehicle, and the like. Spacecraft include airplanes, rockets, space shuttles, and spacecraft, and the like. Electric toys include fixed or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, and the like. Electric tools include metal cutting electric tools, grinding electric tools, assembly electric tools, and railway electric tools, such as electric drills, electric grinders, electric wrenches, electric screwdrivers, electric hammers, impact drills, concrete vibrators, and electric planers, and the like.

[0085] 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.

[0086] Please refer to Figure 1, which is a schematic diagram of the structure of a vehicle 1000 provided in some embodiments of the present application. A battery 100 is provided inside the vehicle 1000, and the battery 100 can be provided at the bottom, head, or tail of the vehicle 1000. The battery 100 can be used to power the vehicle 1000. For example, the battery 100 can serve as an operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 200 and a motor 300. The controller 200 is used to control the battery 100 to power the motor 300, for example, for starting, navigating, and meeting the power requirements of the vehicle 1000 during operation.

[0087] In some embodiments of the present application, the battery 100 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 .

[0088] Please refer to Figure 2, which is an exploded view of a battery 100 according to an embodiment of the present application. The battery 100 comprises a connector 10, a housing 40, and battery cells 30, with the battery cells 30 housed within the housing 40. The connector 10 is used to cool, insulate, or heat the battery cells 30. The connector 10 can be entirely or partially located within the housing 40.

[0089] The housing 40 is used to provide a storage space for the battery cells 30. The housing 40 can adopt a variety of structures. In some embodiments, the housing 40 can include a first portion 41 and a second portion 42. The first portion 41 and the second portion 42 cover each other, and the first portion 41 and the second portion 42 together define a storage space for accommodating the battery cells 30. The second portion 42 can be a hollow structure with one end open, and the first portion 41 can be a plate-like structure. The first portion 41 covers the open side of the second portion 42, so that the first portion 41 and the second portion 42 together define a storage space; the first portion 41 and the second portion 42 can also be hollow structures with one end open, and the open side of the first portion 41 covers the open side of the second portion 42. Of course, the housing 40 formed by the first portion 41 and the second portion 42 can have a variety of shapes, such as a cylinder, a rectangular parallelepiped, etc.

[0090] In some embodiments, the box 40 may serve as part of the chassis structure of the vehicle 1000. For example, a portion of the box 40 may form at least a portion of the floor of the vehicle 1000, or a portion of the box 40 may form at least a portion of a cross member or a longitudinal member of the vehicle 1000.

[0091] Of course, in some embodiments, the battery 100 may not include the case 40 , but rather a plurality of battery cells 30 may be electrically connected and formed into a whole through necessary fixing structures before being assembled into the vehicle 1000 .

[0092] In the battery 100, there may be multiple battery cells 30, and the multiple battery cells 30 may be connected in series, in parallel, or in a hybrid connection. A hybrid connection refers to a combination of series and parallel connections among the multiple battery cells 30. The multiple battery cells 30 may be directly connected in series, in parallel, or in a hybrid connection, and then the entire battery cell 30 may be housed within the housing 40. Of course, the battery 100 may also comprise a battery module composed of multiple battery cells 30 connected in series, in parallel, or in a hybrid connection, and then the multiple battery modules may be further connected in series, in parallel, or in a hybrid connection to form an entire battery cell, which is then housed within the housing 40. The battery 100 may also include other functional components, such as a busbar for electrically connecting the multiple battery cells 30.

[0093] Each battery cell 30 may be a secondary battery or a primary battery. A secondary battery refers to a battery cell 30 that can be recharged to activate the active material after the battery cell 30 is discharged and can continue to be used. A primary battery refers to a battery cell 30 that cannot be recharged to activate the active material after the battery cell 30's power is exhausted and can continue to be used. The battery cell 30 may also be a lithium-ion battery cell, a sodium-ion battery cell, a sodium-lithium-ion battery cell, a lithium metal battery cell, a sodium metal battery cell, a lithium-sulfur battery cell, a magnesium-ion battery cell, a nickel-hydrogen battery cell, a nickel-cadmium battery cell, a lead-acid battery cell, etc., but is not limited thereto. The battery cell 30 may be a cylindrical battery cell, a prismatic battery cell, a soft-pack battery cell, or a battery cell of another shape. Prismatic battery cells include square-shell battery cells, blade-shaped battery cells, and polygonal prismatic batteries. Polygonal prismatic batteries, for example, hexagonal prismatic batteries, are not particularly limited in this application.

[0094] For the convenience of description, the following embodiments are described using a connector 10 according to an embodiment of the present application.

[0095] Referring to Figures 3 to 5, the present application provides a connector 10, which includes a base 11 and a first terminal 16. The base 11 has a plug-in side 101 and a fixed side 102 arranged opposite to the plug-in side 101; the first terminal 16 is used to electrically connect to a power source, the first terminal 16 is connected to the base 11, and the first terminal 16 is located on the plug-in side 101; the base 11 is also provided with a flow channel 110 for conveying fluid, and the two ports of the flow channel 110 are respectively located on the plug-in side 101 and the fixed side 102.

[0096] It should be noted that the connector 10 can be installed on the battery housing 40 as a plug-in module of the battery 100, or it can be plugged into and mated with the plug-in module on the battery housing 40. When the connector 10 is installed on the housing 40, the flow channel 110 can be directly connected to the interior of the housing 40 or connected through a pipe, so that dry gas can be introduced when the interior of the housing 40 needs to be dried, or fire extinguishing agent can be introduced when a fire in the housing 40 needs to be extinguished. When the connector 10 is in a structure that plugs into and mated with the plug-in module on the battery 100, the end of the flow channel 110 near the fixed side 102 can be connected to a gas source, etc., to supply dry gas to the battery housing 40, or connected to a fire extinguishing agent source, etc., to supply fire extinguishing agent to the housing 40.

[0097] The base 11 has a plug-in side 101 and a fixed side 102. The plug-in side 101 refers to the side of the base 11 facing the external plug-in module when the connector 10 is plugged into the external plug-in module. The fixed side 102 is the other side opposite to the plug-in side 101. It is not limited to the fixed side 102 being connected to the box 40 when the connector 10 is installed on the box 40. The base 11 can be embedded in the box 40 or integrated with a part of the structure of the box 40. The plug-in side 101 of the base 11 can be connected to the box 40, or the fixed side 102 of the base 11 can be connected to the box 40.

[0098] The first terminal 16 may be a power terminal, and the first terminal 16 may be a columnar or cylindrical conductor; the number of the first terminals 16 may be, but is not limited to, two.

[0099] The flow channel 110 can be used to transport fluids such as gas, liquid, powder, or particles. When transporting dry gas, it promotes the escape of air from the box 40, discharging moisture from the box 40 to dry the interior of the box 40. It can also be used to transport flame-retardant media (such as carbon dioxide or dry powder fire extinguishing agents) to extinguish fires.

[0100] The base 11 of the connector 10 provided in the embodiment of the present application can be plugged into an external plug-in module to enable the battery 100 to be electrically connected to the external circuit through the first terminal 16, and at the same time, the interior of the housing 40 is connected to the external fluid supply device through the flow channel 110 to facilitate the delivery of fluid into the housing 40. For example, if the fluid is a dry gas, the dry gas enters the interior of the housing 40 and blows out the moisture inside the housing 40 to dry the interior of the housing 40. For another example, if the fluid is a fire extinguishing agent, the fire extinguishing agent enters the interior of the housing 40 to extinguish the fire inside the housing 40, which helps to improve the safety performance of the battery 100. This helps to reduce the number of connectors 10 on the housing 40 and helps to simplify the structure of the housing 40. After the connector 10 is plugged into the external plug-in module, the connection of the circuit and the pipeline can be achieved simultaneously, which simplifies the battery connection process and improves the battery installation efficiency.

[0101] In one embodiment, referring to FIG. 3 to FIG. 5 , the connector 10 further includes a valve plug 12 for controlling the on / off state of the flow channel 110 . The valve plug 12 is installed in the flow channel 110 .

[0102] The valve plug 12 may be, but is not limited to, a spherical, sheet-like, or conical structure. When the valve plug 12 is spherical or conical, it may be confined within the flow channel 110. When the valve plug 12 moves to one end of the flow channel 110 near the plug-in side 101, it blocks the flow channel 110, preventing the flow of fluid. When the valve plug 12 moves toward the other end of the flow channel 110, the flow channel 110 is opened, allowing the flow of fluid. When the valve plug 12 is sheet-like, it may be a one-way valve disc, hinged to the inner wall of the flow channel 110, or a one-way valve disc with one end fixed to the base 11 by injection molding.

[0103] By installing the valve plug 12 in the flow channel 110, when the valve plug 12 moves, the connection and disconnection of the pipeline of the connector 10 can be controlled so that the pipeline is disconnected when air supply is not required.

[0104] In one embodiment, referring to Figures 3 to 5, the flow channel 110 includes a sliding hole section 1101 and a limiting hole section 1103. The sliding hole section 1101 and the limiting hole section 1103 are connected to each other. The limiting hole section 1103 is provided at one end of the sliding hole section 1101 away from the fixed side 102. The cross-sectional area of ​​the limiting hole section 1103 is smaller than the cross-sectional area of ​​the sliding hole section 1101; one end of the valve plug 12 is plugged into the limiting hole section 1103 to block the limiting hole section 1103; the other end of the valve plug 12 is slidably engaged with the inner wall of the sliding hole section 1101.

[0105] It can be understood that when the valve plug 12 moves toward the limiting hole section 1103, the end of the valve plug 12 away from the limiting hole section 1103 slides with the inner wall of the sliding hole section 1101 to keep the valve plug 12 sliding along the flow channel 110. When the end of the valve plug 12 close to the limiting hole section 1103 is inserted into the limiting hole section 1103, the end of the valve plug 12 blocks the limiting hole section 1103, thereby blocking the flow channel 110. The valve plug 12 can slide toward the limiting hole section 1103 under the action of air pressure, elastic force, magnetic force, or gravity to achieve automatic blocking of the flow channel 110.

[0106] The cross-sectional area of ​​one end of the valve plug 12 that is plugged into the limiting hole section 1103 is smaller than the cross-sectional area of ​​the other end of the valve plug 12 , and the cross-sectional area of ​​the end of the valve plug 12 away from the limiting hole section 1103 can be larger than the cross-sectional area of ​​the limiting hole section 1103 .

[0107] By controlling the cross-sectional area of ​​the limiting hole section 1103 to be smaller than the cross-sectional area of ​​the sliding hole section 1101, the valve plug 12 can be prevented from sliding out of the limiting hole section 1103, and the valve plug 12 can be allowed to slide in the flow channel 110, so that when the valve plug 12 slides to the limiting hole section 1103, the fluid is cut off, thereby closing the flow channel 110. When the valve plug 12 slides away from the limiting hole section 1103, the limiting hole section 1103 can be opened, so that the flow channel 110 is connected.

[0108] In one embodiment, referring to FIG. 3 to FIG. 5 , the valve plug 12 includes a sliding section 121 and a plug head section 123 . The sliding section 121 slides with the inner wall of the sliding hole section 1101 , and the plug head section 123 is inserted into the limiting hole section 1103 .

[0109] The cross-sectional area of ​​the plug section 123 is smaller than the cross-sectional area of ​​the sliding section 121 , which can prevent the sliding section 121 from sliding out of the limiting hole section 1103 .

[0110] The limiting hole section 1103 can be a circular hole or a square hole, etc. When the limiting hole section 1103 is a circular hole, the plug section 123 can be a columnar, spherical or conical structure. When the limiting hole section 1103 is a rectangular hole, the plug section 123 can be a prism, a polygonal pyramid or other structures.

[0111] The sliding hole section 1101 can be a circular hole or a square hole, etc. When the sliding hole section 1101 is a circular hole, the sliding section 121 can be a cylindrical or prismatic structure. When the sliding hole section 1101 is a square hole, the sliding section 121 can be a cylindrical or prismatic structure.

[0112] The valve plug 12 slides along the sliding hole section 1101, and when the valve plug 12 slides toward the limiting hole section 1103, it drives the plug head section 123 to insert into the limiting hole section 1103, thereby blocking the fluid; when the valve plug 12 moves away from the limiting hole section 1103, it drives the plug head section 123 to disengage from the limiting hole section 1103, thereby releasing the fluid, thereby controlling the connection or disconnection of the flow channel 110 by pushing the valve plug 12 to slide.

[0113] In one embodiment, referring to Figures 3 to 5, the flow channel 110 further includes a flared section 1102 connecting the limiting hole section 1103 and the sliding hole section 1101, and the cross-sectional area of ​​the flared section 1102 gradually increases from the limiting hole section 1103 toward the sliding hole section 1101.

[0114] The flared section 1102 may be, but is not limited to, tapered. When the valve plug 12 slides toward the limiting hole section 1103, the plug section 123 enters the flared section 1102, and the flared section 1102 can guide the plug section 123 to align with the limiting hole section 1103 so that the plug section 123 is inserted into the limiting hole section 1103.

[0115] By adopting the expanded section 1102 , the plug section 123 can be guided to be inserted into the limiting hole section 1103 , so as to block the flow channel 110 .

[0116] In one embodiment, referring to FIG. 3 to FIG. 5 , the valve plug 12 further includes a guide section 122 connecting the sliding section 121 and the plug head section 123 , and the guide section 122 is adapted to the flaring section 1102 .

[0117] The guide section 122 is adapted to the flaring section 1102, and the cross-sectional area of ​​the guide section 122 gradually increases from one end of the plug section 123 toward the sliding section 121. When the plug section 123 is inserted into the limiting hole section 1103, the outer peripheral wall of the guide section 122 can fit with the inner wall of the flaring section 1102. Of course, considering the assembly error, there may also be a tiny gap between the outer peripheral wall of the guide section 122 and the inner wall of the flaring section 1102.

[0118] When the guide section 122 is inserted into the flared section 1102 , the outer peripheral wall of the guide section 122 abuts against the inner wall of the flared section 1102 , which can improve the stability of the valve plug 12 in the flow channel 110 , prevent the valve plug 12 from shaking, and limit the valve plug 12 from moving further toward the limiting hole section 1103 .

[0119] In one embodiment, referring to Figures 3 to 5, a first air hole 1220 for communicating with the flaring section 1102 is provided on the guide section 122, and a second air hole 1210 connecting the first air hole 1220 and the sliding hole section 1101 is provided on the sliding section 121. The second air hole 1210 passes through one end of the sliding section 121 facing away from the flaring section 122.

[0120] The end of the first air hole 1220 away from the second air hole 1210 may be located on the outer peripheral wall of the guide section 122. When the guide section 122 abuts against the inner wall of the flared section 1102, the opening of the first air hole 1220 can be blocked. The number of first air holes 1220 can be one or more, such as two, three, or four. The multiple first air holes 1220 can be arranged around the axis of the guide section 122. The number of second air holes 1210 can be one or more. Multiple first air holes 1220 can be connected to one second air hole 1210, one first air hole 1220 can be connected to multiple second air holes 1210, or there can be a one-to-one correspondence between the first air holes 1220 and the second air holes 1210.

[0121] When the valve plug 12 leaves the limiting hole section 1103, a portion of the fluid can enter the sliding hole section 1101 from the limiting hole section 1103 through the expanding section 1102, and another portion of the fluid can enter the sliding hole section 1101 from the expanding section 1102 through the first air hole 1220 and the second air hole 1210, so that the flow channel 110 is unobstructed.

[0122] In one embodiment, referring to Figures 3 to 5, the connector 10 further includes an elastic member 13 and a limiting member 14. The elastic member 13 is used to push the plug section 123 into the limiting hole section 1103. The limiting member 14 is installed at one end of the sliding hole section 1101 away from the limiting hole section 1103. One end of the elastic member 13 is abutted and connected to the valve plug 12, and the other end of the elastic member 13 is abutted and connected to the limiting member 14.

[0123] The limiting member 14 can be detachably mounted in the sliding hole section 1101 , such as by interference fit or snap connection, or can be fixed in the sliding hole section 1101 by injection molding or gluing.

[0124] By adopting the limiter 14, the elastic member 13 and the valve plug 12 can be restricted from sliding out from the end of the sliding hole section 1101 away from the limiter hole section 1103. The elastic member 13 can push the valve plug 12 toward the limiter hole section 1103 to realize automatic closing of the flow channel 110.

[0125] In one embodiment, referring to FIG. 3 to FIG. 5 , the elastic member 13 is a spring; and / or the limiting member 14 is a snap ring.

[0126] The spring pushes the valve plug 12 toward the limiting hole section 1103, inserting the plug head section 123 into the limiting hole section 1103. The spring is compressed within the sliding hole section 1101. When the limiting hole section 1103 pushes the valve plug 12 away from the limiting hole section 1103, the valve plug 12 compresses the spring, leaving the limiting hole section 1103, and the flow channel 110 is connected.

[0127] Optionally, a positioning ring groove may be provided in the sliding hole section 1101 . The positioning ring groove is arranged around the axis of the sliding hole section 1101 . The positioning ring groove is used for a snap ring to be inserted into so as to locate the snap ring.

[0128] By using a spring to abut against the retaining ring and the valve plug 12, the valve plug 12 can be pushed to slide, so that the plug head section 123 is automatically inserted into the limiting hole section 1103; the retaining ring can stop the spring to prevent the spring from sliding out of the end of the sliding hole section 1101 away from the limiting hole section 1103, and facilitate the maintenance of the valve plug 12, spring and retaining ring.

[0129] In one embodiment, referring to FIG. 3 to FIG. 5 , a first sealing ring 15 is sleeved on the plug section 123 .

[0130] The first sealing ring 15 can be a rubber ring or a silicone ring, etc. The number of the first sealing ring 15 can be, but is not limited to, one.

[0131] By adopting the first sealing ring 15 , the plug section 123 can be inserted into the limiting hole section 1103 , thereby enhancing the sealing effect between the plug section 123 and the inner wall of the limiting hole section 1103 .

[0132] In one embodiment, a first annular groove 1230 is formed on the outer peripheral wall of the plug section 123 . The first annular groove 1230 is arranged around the central axis of the valve plug 12 , and the first sealing ring 15 is fitted and placed in the first annular groove 1230 .

[0133] The depth of the first annular groove 1230 can be smaller than the difference between the radii of the inner and outer rings of the first sealing ring 15. In this way, when the first sealing ring 15 is placed in the first annular groove 1230, it can protrude outward so that the protruding part can abut against the inner wall of the limiting hole section 1103 to achieve sealing.

[0134] By adopting the first annular groove 1230 , the first sealing ring 15 can be prevented from sliding on the plug section 123 , so as to keep the position of the first sealing ring 15 stable during the process of inserting or withdrawing the plug section 123 into or out of the limiting hole section 1103 .

[0135] In other embodiments, referring to FIG. 6 , FIG. 7 and FIG. 8 , the connector 20 includes an air guide column 22 disposed on the plugging side 201 . The air guide column 22 defines an air vent 2201 in communication with the flow channel 210 .

[0136] The connector 20 includes a base 21 and a first terminal 25. The first terminal 25 is installed on the base 21. The base 21 has a plug-in side 201 and a fixed side 202. The plug-in side 201 and the fixed side 202 refer to the opposite sides of the base 21. A flow channel 210 is opened in the base 21, and the two ends of the flow channel 210 are respectively located at the two ends of the base 21.

[0137] The air guide column 22 can be a metal column or a plastic column integrated with the base 21. When the connector 20 is plugged into the external plug-in module (which can be the connector 10 shown in Figures 3-5), the air guide column 22 is inserted into the flow channel of the external plug-in module, so that the vent 2201 is connected to the external flow channel.

[0138] The air guide column 22 can be inserted into the flow channel of the external plug-in module. When the air guide column 22 is inserted into the external flow channel, it can communicate with the external flow channel to facilitate fluid transportation.

[0139] In one embodiment, referring to FIG. 6 to FIG. 8 , a notch 2210 communicating with the vent 2201 is formed at one end of the air guide column 22 away from the base 21 . The notch 2210 penetrates the outer wall of the air guide column 22 .

[0140] The depth direction of the notch groove 2210 may be along the axial direction or the radial direction of the air guide column 22 , and the notch groove 2210 may pass through the outer peripheral surface of the end portion of the air guide column 22 .

[0141] This facilitates the fluid to flow from the side of the air guide column 22 and avoids blocking the fluid flow when the end of the air guide column 22 abuts against a plane (such as the end surface of the plug section 123 in Figures 4 and 5).

[0142] In one embodiment, referring to Figures 6 to 8, the air guide column 22 includes an insertion section 222 and an abutment column 221. The abutment column 221 is provided at one end of the insertion section 222 away from the base 21. The cross-sectional area of ​​the abutment column 221 is smaller than the cross-sectional area of ​​the insertion section 222.

[0143] The notch 2210 can be formed on the abutting column 221 or the notch 2210 can be formed by cutting the abutting column 221 into multiple parts along its axial surface. The end of the plug section 222 close to the abutting column 221 can be provided with a chamfered structure to facilitate the insertion of the plug section 222 into the external flow channel.

[0144] When the connector 20 is plugged into the external plug-in module, the abutment column 221 is first inserted into the external flow channel. When a valve plug is provided in the external flow channel, the abutment column 221 pushes the valve plug to slide. Since the cross-sectional area of ​​the abutment column 221 is small, it is convenient to guide the gas guide column 22 to be inserted into the external flow channel, and when the notch groove 2210 is connected to the external flow channel, the gap between the notch groove 2210 and the inner wall of the external flow channel can be increased to facilitate the circulation of the fluid.

[0145] In one embodiment, a second sealing ring 23 is sleeved on the plug-in section 222 .

[0146] The second sealing ring 23 can be a rubber ring or a silicone ring, etc., and the number of the second sealing ring 23 can be one or more.

[0147] Through the second sealing ring 23, when the plug-in section 222 is inserted into the external air channel, the second sealing ring 23 can seal the gap between the air guide column 22 and the inner wall of the external flow channel to prevent air leakage and keep the first terminal 25 and the flow channel 210 isolated.

[0148] In one embodiment, referring to FIG. 6 to FIG. 8 , a second annular groove 2202 is defined on the outer peripheral wall of the plug-in section 222 . The second annular groove 2202 is disposed around the central axis of the air guide column 22 , and the second sealing ring 23 is fitted into the second annular groove 2202 .

[0149] The depth of the second annular groove 2202 can be smaller than the difference between the radii of the inner and outer rings of the second sealing ring 23. In this way, when the second sealing ring 23 is placed in the second annular groove 2202, it can protrude outward so that the protruding part can be against the inner wall of the external flow channel (which can be the limiting hole section 1103 in Figure 4) to achieve sealing.

[0150] When the connector 20 is plugged into an external plug-in module, the plug-in section 222 may be partially or completely inserted into the external flow channel, and the second annular groove 2202 is located at the position where the plug-in section 222 is inserted into the external flow channel.

[0151] By adopting the second annular groove 2202 , the second sealing ring 23 can be prevented from sliding on the plug-in section 222 , so as to keep the position of the second sealing ring 23 stable when the air guide column 22 is inserted into or withdrawn from the external flow channel.

[0152] In one embodiment, referring to FIG. 6 to FIG. 8 , a control valve 24 is installed at one end of the flow channel 210 close to the fixed side 202 .

[0153] The control valve 24 can be a solenoid valve or a check valve. The solenoid valve can cut off the flow channel 210 when needed to prevent the fluid from flowing, while the check valve can allow the fluid to flow in one direction to prevent the fluid from flowing in the reverse direction.

[0154] By adopting the control valve 24 , the on-off of the flow channel 210 can be controlled to prevent the flow channel 210 from leaking or foreign matter from entering the flow channel 210 after the external plug-in module is unplugged.

[0155] In one embodiment, referring to FIG. 6 to FIG. 8 , the first terminal 25 is detachably connected to the base 21 .

[0156] The first terminal 25 and the base 21 can be assembled together by snap connection or screw connection.

[0157] This can facilitate modular processing and assembly of the connector 20 , helping to save production and maintenance costs.

[0158] In some embodiments, referring to FIG. 3 to FIG. 5 , the connector 10 further includes a second terminal 17 for electrically connecting to a signal line. The second terminal 17 is mounted on the base 11 .

[0159] 6 to 8 , the first terminals 25 and second terminals 26 of the connector 20 are interchangeable with the first terminals 16 and second terminals 17 of the connector 10. The connectors 10 and 20 can be plug-fitted, so that when plugged in, both the circuit and the pipeline can be connected.

[0161] In one embodiment, referring to FIG. 3 to FIG. 5 , the second terminal 17 is detachably connected to the base 11 .

[0162] The second terminal 17 and the base 11 can be assembled together by snap connection or screw connection.

[0163] This can facilitate modular processing and assembly of the connector 10 , helping to save production and maintenance costs.

[0164] 3 to 5 , the connector 10 further includes a third terminal 18 for connecting to ground, and the third terminal 18 is mounted on the base 11. In this embodiment, the connector 10 is a male connector, and the third terminal 18 may be a cylindrical structure.

[0165] In other embodiments, referring to FIG6 , the connector 20 further includes a third terminal 27 for connecting to the ground, and the third terminal 27 is mounted on the base 21. In this embodiment, the connector 20 is a female connector, and the third terminal 27 can be a guide post structure.

[0166] The third terminal is detachably connected to the base, such as by a snap connection or screw connection, and assembled together. This facilitates modular processing and assembly of the connector, which helps save production and maintenance costs.

[0167] The third terminal is electrically connected to the ground, thereby improving the safety of the connector.

[0169] The flow channel 110 may transport the fluid into the box body 40 through an air pipe, or may be directly connected to the interior of the box body 40 .

[0170] The connector 10 can be plugged into an external plug-in module to simultaneously achieve connectivity between circuits and pipelines, which helps to simplify battery connection and improve battery safety performance.
