Description

Technical Field

[0001] This disclosure relates to the field of battery technology, and in particular to an electrical connector, a sampling assembly, a battery, and an electrical device. Background Technology

[0002] In batteries using related technologies, to facilitate maintenance of the sampling component, the sampling element and the circuit board can be detachably connected via an electrical connector. However, when these sampling components are used in high-temperature and high-humidity environments, condensation can easily form inside the electrical connector. These condensate droplets may cause non-electrically connected terminals within the connector to become conductive, affecting the sampling performance of the sampling component. Summary of the Invention

[0003] The purpose of this disclosure is to provide an electrical connector, sampling assembly, battery, and electrical device that aims to reduce the risk of electrical connection failure at the connection end of the electrical connector due to condensation.

[0004] This disclosure provides an electrical connector, including a housing, a first electrical connection portion, a second electrical connection portion, and a separator. The first electrical connection portion is located within the housing and includes a first connecting end and a second connecting end electrically connected to the first connecting end. The second electrical connection portion is located within the housing and includes a third connecting end and a fourth connecting end electrically connected to the third connecting end. The separator, used to block water droplets, is located within the housing and between the first and second electrical connection portions.

[0005] Because a partition is provided between the first electrical connection and the second electrical connection, the partition can form a barrier between the first electrical connection and the second electrical connection. When condensation forms inside the housing of the electrical connector, it helps to block the first electrical connection and its connecting end and the second electrical connection and its connecting end, thereby increasing the difficulty for condensation to simultaneously contact the first electrical connection and the second electrical connection, and thus reducing the risk of the first electrical connection and the second electrical connection becoming conductive due to condensation.

[0006] In some embodiments of the electrical connector, the separator includes a first end and a second end disposed opposite to each other. A first connecting end of the first electrical connection is closer to the first end of the separator than a second connecting end, and a second connecting end of the first electrical connection is closer to the second end of the separator than a first connecting end. A third connecting end of the second electrical connection is closer to the first end of the separator than a fourth connecting end, and a fourth connecting end of the second electrical connection is closer to the second end of the separator than a third connecting end. The distance between the first connecting end and the second end is greater than the distance between the third connecting end and the second end, and the distance between the second connecting end and the first end is less than the distance between the fourth connecting end and the first end.

[0007] The above arrangement allows for a staggered arrangement of the connecting ends of the first and second electrical connections located at the same end of the housing. This helps to lengthen the distance between the connecting ends of the first and second electrical connections that are close to the same end. Combined with the partition, this further extends the flow path of condensate, better preventing the first and second electrical connections from becoming conductive due to condensate. When this electrical connector is used to connect the sampling part of the sampling assembly to the corresponding sampling connection part of the circuit board, it helps to improve the sampling performance of the sampling assembly.

[0008] In some embodiments of the electrical connector, the first electrical connection portion, the second electrical connection portion, and the partition portion all extend along the length direction of the housing.

[0009] The above arrangement facilitates the rational layout of the various parts of the electrical connector. The relatively long lengths of the first electrical connection, the second electrical connection, and the separator facilitate the extension of the path for condensate to flow between the adjacent connection ends in the first and second electrical connections, thereby better preventing the first and second electrical connections from becoming conductive due to condensate.

[0010] In some embodiments of the electrical connector, the first electrical connection portion, the second electrical connection portion, and the separator portion are arranged in parallel at intervals.

[0011] The above arrangement facilitates the rational layout of the various parts of the electrical connector. The parallel spacing of the first electrical connection, the second electrical connection, and the partition helps to reduce the possibility of the first electrical connection and the second electrical connection becoming connected due to condensation moving along the partition, thereby improving the partitioning effect.

[0012] In some embodiments of the electrical connector, the first connection end, the second connection end, the third connection end, and the fourth connection end are all plug-in ends or crimp ends that connect to the pins.

[0013] Each connection end is a plug or crimp end that connects to the pin, which facilitates the quick connection and disconnection of the electrical connector and the electrical components it is connected to, and is beneficial for the assembly and maintenance of the electrical connector and the electrical components it is connected to, such as the sampling component.

[0014] In some embodiments of the electrical connector, the housing includes a shell and a cover. A first electrical connection portion and a second electrical connection portion are disposed on the shell. The cover covers the shell and is detachably connected to the shell, and a partition portion is disposed on at least one of the shell and the cover.

[0015] The above structure not only facilitates the processing and assembly of the various components of the electrical connector, but also improves the assembly efficiency and accuracy of the electrical connector.

[0016] In some embodiments of the electrical connector, the separator includes a first isolation strip and a second isolation strip. The first isolation strip is disposed on one of the housing and the cover. The second isolation strip is disposed on the other of the housing and the cover, and the end of the second isolation strip facing the first isolation strip engages with the end of the first isolation strip facing the second isolation strip.

[0017] The above arrangement helps to better separate the first electrical connection and the second electrical connection between the shell and the cover, and helps to prevent condensate from flowing directly between the inner walls of the shell and the cover, which would cause the first electrical connection and the second electrical connection to become connected.

[0018] In some embodiments of the electrical connector, the housing and cover are connected by a snap-fit ​​structure. This arrangement facilitates quick assembly and maintenance of the electrical connector.

[0019] In some embodiments of the electrical connector, the housing and / or cover are provided with through holes for connection terminals that are electrically connected to a first connection terminal, a second connection terminal, a third connection terminal, and a fourth connection terminal, respectively.

[0020] This configuration facilitates the rapid assembly and maintenance of the electrical connector and connected electrical components. In some embodiments of the electrical connector, the housing includes a bottom wall and side walls disposed on the outer periphery of the bottom wall. A first electrical connection portion and a second electrical connection portion are both disposed on the bottom wall, and a first connection end, a second connection end, a third connection end, and a fourth connection end are spaced apart from the side walls of the housing.

[0021] In some embodiments of the electrical connector, the housing includes a bottom wall and a side wall disposed on the outer periphery of the bottom wall. A first electrical connection portion and a second electrical connection portion are both disposed on the bottom wall. A first connection end, a second connection end, a third connection end and a fourth connection end are spaced apart from the side wall of the housing.

[0022] This design helps prevent condensation on the outer casing wall from contacting the connection ends, thus reducing the risk of the first electrical connection and the second electrical connection becoming conductive.

[0023] In some embodiments of the electrical connector, the housing includes a bottom wall and a side wall disposed on the outer periphery of the bottom wall, and the partition is sealed to the bottom wall and the cover of the housing.

[0024] This arrangement allows the partition to better separate the first electrical connection and the second electrical connection between the shell and the cover, and helps to prevent condensate from flowing directly between the inner walls of the shell and the cover, which would cause the first electrical connection and the second electrical connection to become connected.

[0025] In some embodiments of the electrical connector, the separator includes a first end and a second end disposed opposite to each other, with the first end and a sidewall and the second end and the sidewall respectively spaced apart.

[0026] Setting intervals allows the partition to function as a divider while maintaining airflow between the two spaces separated by the partition. It also ensures that the terminals of the electrical components connected by the first electrical connection, the second electrical connection, and the electrical connector are located in roughly the same working environment.

[0027] In some embodiments of the electrical connector, the housing and the cover are connected by a snap-fit ​​structure, which includes a first snap-fit ​​portion and a second snap-fit ​​portion. The first snap-fit ​​portion is disposed on the cover. The second snap-fit ​​portion is disposed on the bottom wall of the housing and located within a gap.

[0028] The second snap-fit ​​part of the snap-fit ​​structure is located within the gap, which facilitates the compact arrangement of electrical connectors.

[0029] In some embodiments of the electrical connector, a first electrical connection portion or a second electrical connection portion includes a groove and a crimping portion. The groove includes a receiving groove for accommodating a connecting terminal. The crimping portion is connected to the opening side of the receiving groove at the end of the groove in the extending direction, and includes a crimping channel communicating with the opening of the receiving groove. In a cross-section perpendicular to the extending direction of the groove, the minimum through-size of the crimping channel is smaller than the opening size of the receiving groove.

[0030] The above configuration facilitates the assembly of electrical connectors and connected electrical components via press-fitting, enabling rapid assembly and preventing the terminals of electrical components from detaching from the receiving slot through the press-fit channel. This assembly method is suitable for situations where operating space is limited and pin insertion / removal is not feasible.

[0031] In some embodiments of the electrical connector, on a cross section perpendicular to the extension direction of the groove, the size of the press-in channel gradually decreases to a minimum through size and then gradually increases from the side away from the receiving groove to the side closer to the receiving groove.

[0032] This setup facilitates the assembly of electrical connectors and connected electrical components via press-fitting, enabling quick and smooth assembly of the connectors and their corresponding electrical components.

[0033] In some embodiments of the electrical connector, the housing is made of an insulating and waterproof material; and / or the separator is made of an insulating and waterproof material.

[0034] The above settings help to better achieve the insulation and waterproofing effects of the electrical connector, and improve the separation effect of the separator.

[0035] A second aspect of this disclosure provides a sampling assembly, including a sampling element, a circuit board, and an electrical connector. The sampling element includes a sampling section and a first sampling element connection terminal and a second sampling element connection terminal connected to the sampling section. The circuit board includes a circuit board body and a first circuit board connection terminal and a second circuit board connection terminal connected to the circuit board body. The electrical connector is the same as that of the first aspect of this disclosure. The first sampling element connection terminal is electrically connected to a first connection end of the first electrical connection section, the second sampling element connection terminal is electrically connected to a third connection end of the second electrical connection section, the first circuit board connection terminal is electrically connected to a second connection end of the first electrical connection section, and the second circuit board connection terminal is electrically connected to a fourth connection end of the second electrical connection section.

[0036] The sampling component disclosed herein uses the disclosed electrical connector. Since the electrical connector is provided with a separation part, it is beneficial to reduce the risk of conduction between its first electrical connection part and second electrical connection part due to condensation. When the sampling part of the sampling component and the corresponding sampling connection part of the circuit board are connected through the electrical connector, it is beneficial to improve the sampling performance of the sampling component.

[0037] In some embodiments of the sampling assembly, the first sampling element connection terminal, the second sampling element connection terminal, the first circuit board connection terminal, and the second circuit board connection terminal each include a pin. The first connection terminal, the second connection terminal, the third connection terminal, and the fourth connection terminal are all plug-in terminals or crimp terminals that connect to the corresponding pins.

[0038] The plug or crimp terminals that connect to the pins facilitate quick connection and disconnection of the electrical connector with its connected sampling part and sampling connection part, and are beneficial for the assembly and maintenance of the electrical connector and sampling assembly.

[0039] In some embodiments of the sampling assembly, the partition includes a first end and a second end disposed opposite to each other; a first connection end of the first electrical connection is closer to the first end of the partition than a second connection end, and a second connection end of the first electrical connection is closer to the second end of the partition than a first connection end; a third connection end of the second electrical connection is closer to the first end of the partition than a fourth connection end, and a fourth connection end of the second electrical connection is closer to the second end of the partition than a third connection end; the distance between the first connection end and the second end is greater than the distance between the third connection end and the second end, and the distance between the second connection end and the first end is less than the distance between the fourth connection end and the first end.

[0040] The distance between the end face of the pin of the first sampling component connection terminal and the sampling part is less than the distance between the end face of the pin of the second sampling component connection terminal and the sampling part; the distance between the end face of the pin of the first circuit board connection terminal and the circuit board body is greater than the distance between the end face of the pin of the second circuit board connection terminal and the circuit board body.

[0041] The above arrangement allows for a staggered arrangement of the connection ends of the first and second electrical connections located at the same end of the casing. This helps to lengthen the distance between the connection ends of the first and second electrical connections that are close to the same end. Combined with the partition, this further extends the flow path of condensate, better preventing the first and second electrical connections from becoming conductive due to condensate. The insertion ends of the pins of the corresponding sampling connections on the sampling unit and circuit board are adapted to the first and second electrical connections, improving the sampling performance of the sampling assembly.

[0042] In some embodiments of the sampling assembly, the first electrical connection portion and the second electrical connection portion each include a groove and two crimping portions disposed at both ends of the groove in the extending direction. The groove includes a receiving groove for accommodating a connection terminal. The crimping portions are connected to the opening side of the receiving groove at the corresponding end in the extending direction of the groove and include a crimping channel communicating with the opening of the receiving groove. In a cross section perpendicular to the extending direction of the groove, the minimum through size of the crimping channel is smaller than the opening size of the receiving groove.

[0043] Each pin includes a main body section and a mating section. Each mating section mates with a corresponding receiving groove and crimping part. The main body section connects the corresponding mating section and the sampling part or the circuit board body.

[0044] The above-mentioned structural arrangement of the first electrical connection part, the second electrical connection part, and the pin facilitates a quick and stable connection between the connection end and the pin, and prevents the pin from coming out of the connection end through the push-in channel.

[0045] In some embodiments of the sampling assembly, each pin also includes an anti-detachment part, which is disposed on the corresponding mating section and spaced apart from the main body section, and the crimping part is located between the corresponding main body section and the anti-detachment part.

[0046] The anti-detachment feature allows the pin to detach from the connection end along the extension direction of the receiving groove.

[0047] A third aspect of this disclosure provides a battery including a battery cell and a sampling component of a second aspect of this disclosure, the sampling component being configured to acquire parameters of the battery cell.

[0048] The battery of this embodiment has the advantages of the sampling component of this embodiment, which helps to improve the sampling performance of the battery, thereby facilitating the battery management system's safe management of the battery.

[0049] A fourth aspect of this disclosure provides an electrical device including a battery according to a third aspect of this disclosure, the battery being configured to supply power to the electrical device.

[0050] The electrical equipment of this disclosure embodiment has the advantages of the battery of this disclosure embodiment, which helps to improve the sampling performance of the battery, thereby facilitating the battery management system to manage the battery safely.

[0068] The sampling components and circuit boards of the battery sampling assembly in the related technology can be electrically connected via electrical connectors.

[0069] In the process of developing this application, the inventors discovered that if the battery operates in a high temperature and high humidity environment, water droplets may condense inside the housing of the electrical connector. The condensed water droplets may cause the connection terminals inside the housing of the electrical connector, which are not electrically connected, to become conductive, resulting in sampling failure.

[0070] To address the aforementioned technical problems, embodiments of this application provide an electrical connector that reduces the risk of continuity at connection ends that are not electrically connected due to condensation. It also provides a sampling component including the electrical connector, a battery using the sampling component, and an electrical device powered by the battery.

[0071] The electrical device of this disclosure includes a battery of this disclosure, which is used to power the electrical device. The battery of this disclosure includes a sampling component of this disclosure. The sampling component of this disclosure includes an electrical connector of this disclosure.

[0072] The electrical equipment can be mobile phones, portable devices, laptops, electric vehicles, electric cars, ships, spacecraft, electric toys, and power tools, etc. For example, spacecraft include airplanes, rockets, space shuttles, and spacecraft, etc. Electric toys include stationary or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc. Power tools include metal cutting power tools, grinding power tools, assembly power tools, and railway power tools, such as electric drills, electric grinders, electric wrenches, electric screwdrivers, electric hammers, impact drills, concrete vibrators, and electric planers.

[0073] The battery in this disclosure refers to a single physical module comprising one or more battery cells to provide higher voltage and capacity. For example, a battery may include a battery module or a battery pack. A battery generally includes a housing for encapsulating one or more battery cells. The housing prevents liquids or other foreign matter from affecting the charging or discharging of the battery cells.

[0074] A battery consists of three levels: individual battery cells, battery modules, and battery packs. An individual battery cell is the smallest unit that makes up a battery module or battery pack.

[0075] Multiple battery cells can be connected in series and / or in parallel via electrode terminals for various applications, such as high-power applications like electric vehicles.

[0076] A battery module is formed by electrically connecting a certain number of battery cells together and placing them in a frame to protect them from external impacts, heat, vibration, etc. With the development of technology, this battery module layer can be omitted, that is, the battery pack can be formed directly from the battery cells.

[0077] A battery pack represents the final state of a battery system installed in high-power electrical devices such as electric vehicles. A battery pack typically includes a casing for housing one or more individual battery cells. The casing prevents liquids or other foreign matter from affecting the charging or discharging of the individual cells. The casing generally consists of a cover and a shell. Most current battery packs are manufactured by assembling a Battery Management System (BMS), thermal management components, and various control and protection systems onto one or more battery modules. This improvement has increased the gravimetric and volumetric energy density of the battery system while significantly reducing the number of components.

[0078] The batteries mentioned in the embodiments of this disclosure include battery cells, battery modules, or battery packs.

[0079] In the embodiments of this disclosure, the battery cell may include lithium-ion batteries, lithium-sulfur batteries, sodium-lithium-ion batteries, sodium-ion batteries, or magnesium-ion batteries, etc., and this disclosure does not limit the specific type of battery cell. The battery cell may be cylindrical, flat, cuboid, or other shapes, and this disclosure does not limit the specific shape of the battery cell. Battery cells are generally classified into three types according to their packaging method: cylindrical battery cells, cuboid / square battery cells, and pouch battery cells, and this disclosure does not limit the specific type of battery cell.

[0080] A single battery cell mainly consists of a cell assembly, a housing, and an end cap assembly. The cell assembly is encapsulated within the housing through the end cap of the end cap assembly.

[0081] The sampling component is coupled to the battery management system (BMS) to acquire battery operating data. It typically includes a circuit board and a sampling element connected to the circuit board via a signal connection. The sampling element acquires battery operating data, such as temperature and pressure. The circuit board is connected to the sampling element to receive the operating data collected by the sampling element and is also connected to the BMS to upload the battery operating data to the BMS. In this embodiment, the sampling element and the circuit board are connected via an electrical connector. The sampling element can be, for example, a temperature sensor or a pressure sensor, and the circuit board can be, for example, a flexible printed circuit (FPC). This disclosure does not limit the specific form of the sampling element and the circuit board.

[0082] Electrical connectors are electromechanical components used to connect electrical circuits. The electrical connectors in this disclosure are primarily used in battery sampling assemblies to connect sampling components to a circuit board. In embodiments not shown, the electrical connectors in this disclosure can also be used in electrical circuits to electrically connect different electrical components. This disclosure does not limit the application of the electrical connectors.

[0083] like Figure 2 , Figures 4 to 11As shown, the electrical connector 7 provided in this embodiment includes a housing, a first electrical connection portion 73, a second electrical connection portion 74, and a partition portion 75. The first electrical connection portion 73 is located inside the housing and includes a first connection end 73A and a second connection end 73B electrically connected to the first connection end 73A. The second electrical connection portion 74 is located inside the housing and includes a third connection end 74A and a fourth connection end 74B electrically connected to the third connection end 74A. The partition portion 75, used to block water droplets, is located inside the housing between the first electrical connection portion 73 and the second electrical connection portion 74.

[0084] Since a partition 75 is provided between the first electrical connection 73 and the second electrical connection 74, the partition 75 can form a barrier between the first electrical connection 73 and the second electrical connection 74. When condensation forms inside the housing of the electrical connector 7, it helps to block the first electrical connection 73 and its connecting end and the second electrical connection 74 and its connecting end, thereby increasing the difficulty for condensation to simultaneously contact the first electrical connection 73 and the second electrical connection 74, and thus reducing the risk of the first electrical connection 73 and the second electrical connection 74 becoming conductive due to condensation.

[0085] When this electrical connector is connected to the sampling section of the sampling component and the corresponding sampling connection section of the circuit board, it helps to improve the sampling performance of the sampling component.

[0086] The separator 75 is configured to prevent at least one of the first connecting end 73A and the second connecting end 73B from communicating with at least one of the third connecting end 74A and the fourth connecting end 74B through condensate within the housing. The separator 75 can completely separate the first electrical connection 73 and the second electrical connection 74, or it can partially separate them. The separation function of the separator 75 can be achieved by increasing the difficulty of electrical connection between any connecting end of the first electrical connection 73 and any connecting end of the second electrical connection 74.

[0087] In some embodiments of the electrical connector 7, the separator 75 includes a first end 75A and a second end 75B disposed opposite to each other. The first connecting end 73A of the first electrical connection 73 is closer to the first end 75A of the separator 75 than the second connecting end 73B, and the second connecting end 73B of the first electrical connection 73 is closer to the second end 75B of the separator 75 than the first connecting end 73A. The third connecting end 74A of the second electrical connection 74 is closer to the first end 75A of the separator 75 than the fourth connecting end 74B, and the fourth connecting end 74B of the second electrical connection 74 is closer to the second end 75B of the separator 75 than the third connecting end 74A. The distance between the first connecting end 73A and the second end 75B is greater than the distance between the third connecting end 74A and the second end 75B, and the distance between the second connecting end 73B and the first end 75A is less than the distance between the fourth connecting end 74B and the first end 75A.

[0088] The above arrangement allows for a staggered arrangement of the connection ends of the first electrical connection 73 and the second electrical connection 74, which are located at the same end of the housing. This helps to lengthen the distance between the connection ends of the first electrical connection 73 and the second electrical connection 74 that are close to the same end. Combined with the partition 75, this further extends the flow path of condensate and better prevents the first electrical connection 73 and the second electrical connection 74 from becoming conductive due to condensate. When this electrical connector is used to connect the sampling part of the sampling assembly to the corresponding sampling connection part of the circuit board, it helps to improve the sampling performance of the sampling assembly.

[0089] In some embodiments of the electrical connector 7, the first electrical connection portion 73, the second electrical connection portion 74, and the partition portion 75 all extend along the length direction of the housing.

[0090] The above arrangement facilitates the rational layout of the various parts of the electrical connector 7. The first electrical connection 73, the second electrical connection 74 and the partition 75 are relatively long, which helps to lengthen the path for condensate to flow between the adjacent connection ends of the first electrical connection 73 and the second electrical connection 74, thereby better preventing the phenomenon of the first electrical connection 73 and the second electrical connection 74 from becoming conductive due to condensate.

[0091] In some embodiments of the electrical connector 7, the first electrical connection portion 73, the second electrical connection portion 74, and the separator portion 75 are arranged in parallel at intervals.

[0092] The above arrangement facilitates the rational layout of the various parts of the electrical connector 7. The parallel spacing of the first electrical connection 73, the second electrical connection 74, and the partition 75 helps to reduce the possibility of the first electrical connection 73 and the second electrical connection 74 becoming connected due to the movement of condensate along the partition 75, thereby improving the partitioning effect of the partition 75.

[0093] In some embodiments of the electrical connector 7, the first connection end 73A, the second connection end 73B, the third connection end 74A and the fourth connection end 74B are all plug-in ends or crimp ends that are connected to the pins.

[0094] Each connection end is a plug or crimp end that connects to the pin, which facilitates the quick connection and disconnection of the electrical connector 7 and the electrical components it is connected to, and facilitates the assembly and maintenance of the electrical connector 7 and the electrical components it is connected to, such as the sampling component.

[0095] In some embodiments of the electrical connector 7, the housing includes a housing 71 and a cover 72. A first electrical connection portion 73 and a second electrical connection portion 74 are disposed on the housing 71. The cover 72 covers the housing 71 and is detachably connected to the housing 71, and a partition portion 75 is disposed on at least one of the housing 71 and the cover 72.

[0096] The outer casing includes a housing 71 and a cover 72, and a first electrical connection portion 73 and a second electrical connection portion 74 are disposed on the housing 71. A partition portion 75 is disposed on the housing 71 and / or the cover 72, which facilitates the processing and assembly of the various components of the electrical connector 7 and improves the assembly efficiency and assembly accuracy of the electrical connector 7.

[0097] In some embodiments of the electrical connector 7, the separator 75 includes a first separator 751 and a second separator 752. The first separator 751 is disposed on one of the housing 71 and the cover 72. The second separator 752 is disposed on the other of the housing 71 and the cover 72, and the end of the second separator 752 facing the first separator 751 engages with the end of the first separator 751 facing the second separator 752.

[0098] This arrangement facilitates better separation of the first electrical connection 73 and the second electrical connection 74 between the housing 71 and the cover 72 by the partition 75, and helps prevent condensate from flowing directly between the inner walls of the housing 71 and the cover 72, which would cause the first electrical connection 73 and the second electrical connection 74 to become connected.

[0099] In some embodiments of the electrical connector 7, the housing 71 and the cover 72 are connected by a snap-fit ​​structure.

[0100] This design facilitates quick assembly and maintenance of electrical connector 7.

[0101] In some embodiments of the electrical connector 7, the housing 71 and / or cover 72 are provided with through holes 711A, 711B, 711C and 711D for connection terminals that are electrically connected to the first connection terminal 73A, the second connection terminal 73B, the third connection terminal 74A and the fourth connection terminal 74B, respectively.

[0102] This arrangement facilitates the rapid assembly and maintenance of the electrical connector 7 with the connected electrical components. In some embodiments of the electrical connector 7, the housing 71 includes a bottom wall 711 and a side wall 712 disposed on the outer periphery of the bottom wall 711. The first electrical connection portion 73 and the second electrical connection portion 74 are both disposed on the bottom wall 711. The first connection end 73A, the second connection end 73B, the third connection end 74A, and the fourth connection end 74B are spaced apart from the side wall 712 of the housing 71.

[0103] This arrangement helps prevent condensation on the outer casing wall from contacting the connection ends, and helps reduce the risk of the first electrical connection 73 and the second electrical connection 74 becoming conductive.

[0104] In some embodiments of the electrical connector 7, the housing 71 includes a bottom wall 711 and a side wall 712 disposed on the outer periphery of the bottom wall 711, and the partition 75 is sealed to the bottom wall 711 and the cover 72 of the housing 71.

[0105] This arrangement allows the partition 75 to better separate the first electrical connection 73 and the second electrical connection 74 between the housing 71 and the cover 72, and helps to prevent condensate from flowing directly between the inner walls of the housing 71 opposite to the cover 72, which would cause the first electrical connection 73 and the second electrical connection 74 to become connected.

[0106] In some embodiments of the electrical connector 7, the separator 75 includes a first end 75A and a second end 75B disposed opposite to each other, with the first end 75A and the sidewall 712 and the second end 75B and the sidewall 712 respectively having a gap.

[0107] Setting an interval allows the partition 75 to function as a separator while maintaining airflow between the two spaces separated by the partition, and allows the terminals of the electrical components connected by the first electrical connection 73, the second electrical connection 74, and the electrical connector to be located in roughly the same working environment.

[0108] In some embodiments of the electrical connector 7, the housing 71 and the cover 72 are connected by a snap-fit ​​structure, which includes a first snap-fit ​​portion and a second snap-fit ​​portion. The first snap-fit ​​portion is disposed on the cover 72. The second snap-fit ​​portion is disposed on the bottom wall 711 of the housing 71 and located within the gap.

[0109] The second snap-fit ​​part of the snap-fit ​​structure is located within the gap, which facilitates the compact arrangement of the electrical connector 7.

[0110] In some embodiments of the electrical connector 7, the first electrical connection portion 73 or the second electrical connection portion 74 includes a groove 731 and a crimping portion 732. The groove 731 includes a receiving groove 731A for accommodating a connecting terminal. The crimping portion 732 is connected to the opening side of the receiving groove 731A at the end of the extending direction of the groove 731, and includes a crimping channel 732A communicating with the opening of the receiving groove 731A. In a cross-section perpendicular to the extending direction of the groove 731, the minimum through-size of the crimping channel 732A is smaller than the opening size of the receiving groove 731A.

[0111] The above configuration facilitates the assembly of the electrical connector 7 and the electrical components connected to it via press-fitting, enabling rapid assembly and preventing the terminals of the electrical components from dislodging from the receiving groove 731A through the press-fitting channel. This assembly method is suitable for situations where operating space is limited and pin insertion / removal is not feasible.

[0112] In some embodiments of the electrical connector 7, on a cross section perpendicular to the extending direction of the groove 731, from the side away from the receiving groove 731A to the side closer to the receiving groove 731A, the size of the press-in channel 732A first gradually decreases to the minimum through size and then gradually increases.

[0113] This setup facilitates the assembly of the electrical connector 7 and the electrical components connected to it via press fitting, enabling quick and smooth assembly of the electrical connector 7 and the corresponding electrical components.

[0114] In some embodiments of the electrical connector 7, the housing is made of an insulating and waterproof material; and / or the separator is made of an insulating and waterproof material. This arrangement facilitates better insulation and waterproofing of the electrical connector 7 and improves the separation effect of the separator.

[0115] The sampling assembly of this embodiment includes a sampling component 6, a circuit board 5, and an electrical connector 7. The sampling component 6 includes a sampling section 61 and a first sampling component connection terminal 62 and a second sampling component connection terminal 63 connected to the sampling section 61. The circuit board 5 includes a circuit board body 51 and a first circuit board connection terminal 521 and a second circuit board connection terminal 522 connected to the circuit board body 51. The electrical connector 7 is the aforementioned electrical connector of this disclosure. The first sampling component connection terminal 62 is electrically connected to a first connection terminal 73A of a first electrical connection section 73. The second sampling component connection terminal 63 is electrically connected to a third connection terminal 74A of a second electrical connection section 74. The first circuit board connection terminal 521 is electrically connected to a second connection terminal 73B of the first electrical connection section 73. The second circuit board connection terminal 522 is electrically connected to a fourth connection terminal 74B of the second electrical connection section 74.

[0116] The sampling component of this embodiment uses the aforementioned electrical connector 7. Since the electrical connector 7 is provided with a partition 75, it is beneficial to reduce the risk of the first electrical connection 73 and the second electrical connection 74 being connected due to condensation. When the sampling part of the sampling component and the corresponding sampling connection part of the circuit board are connected through the electrical connector 7, it is beneficial to improve the sampling performance of the sampling component.

[0117] In some embodiments of the sampling assembly, the first sampling component connection terminal 62, the second sampling component connection terminal 63, the first circuit board connection terminal 521, and the second circuit board connection terminal 522 each include a pin; the first connection terminal 73A, the second connection terminal 73B, the third connection terminal 74A, and the fourth connection terminal 74B are all plug-in terminals or crimp terminals connected to the corresponding pins.

[0118] The plug or crimp terminals that connect to the pins facilitate quick connection and disconnection of the electrical connector 7 with its connected sampling part and sampling connection part, and facilitate the assembly and maintenance of the electrical connector 7 and the sampling assembly.

[0119] In some embodiments of the sampling assembly, the separator 75 includes a first end 75A and a second end 75B disposed opposite to each other. The first connection end 73A of the first electrical connection 73 is closer to the first end 75A of the separator 75 than the second connection end 73B, and the second connection end 73B of the first electrical connection 73 is closer to the second end 75B of the separator 75 than the first connection end 73A. The third connection end 74A of the second electrical connection 74 is closer to the first end 75A of the separator 75 than the fourth connection end 74B. The fourth connection end 74B of the second electrical connection 74 is closer to the second end 75B of the separator 75 than the third connection end 74A. The distance between the first connection end 73A and the second end 75B is greater than the distance between the third connection end 74A and the second end 75B, and the distance between the second connection end 73B and the first end 75A is less than the distance between the fourth connection end 74B and the first end 75A. The distance between the end face of the pin of the first sampling component connection terminal 62 and the sampling part 61 is less than the distance between the end face of the pin of the second sampling component connection terminal 63 and the sampling part 61. The distance between the end face of the pin of the first circuit board connection terminal 521 and the circuit board body 51 is greater than the distance between the end face of the pin of the second circuit board connection terminal 522 and the circuit board body 51.

[0120] The above arrangement allows for a staggered arrangement of the connection ends of the first electrical connection 73 and the second electrical connection 74, which are located at the same end of the outer casing. This helps to lengthen the distance between the connection ends of the first electrical connection 73 and the second electrical connection 74 that are close to the same end. Combined with the partition 75, this further extends the flow path of condensate and better prevents the first electrical connection 73 and the second electrical connection 74 from becoming conductive due to condensate. The insertion ends of the pins of the corresponding sampling connection parts of the sampling unit and the circuit board are adapted to the first electrical connection 73 and the second electrical connection 74, which helps to improve the sampling performance of the sampling component.

[0121] In some embodiments of the sampling assembly, the first electrical connection portion 73 and the second electrical connection portion 74 each include a groove 731 and two crimping portions 732 disposed at both ends of the groove 731 in the extending direction. The groove 731 includes a receiving groove 731A for accommodating a connecting terminal. The crimping portions 732 are connected to the opening side of the receiving groove 731A at the corresponding end in the extending direction of the groove 731, and include a crimping channel 732A communicating with the opening of the receiving groove 731A. In a cross-section perpendicular to the extending direction of the groove 731, the minimum through size of the crimping channel 732A is smaller than the opening size of the receiving groove 731A. Each pin includes body segments 621, 631, 5211, and 5221 and mating segments 622, 632, 5212, and 5222. Each mating segment 622, 632, 5212 and 5222 mates with the corresponding receiving groove (such as receiving groove 731A) and crimping part (such as crimping part 732), and the main body segments 621, 631, 5211 and 5221 connect the corresponding mating segments 622, 632, 5212 and 5222 and the sampling part 61 or the circuit board body 51.

[0122] The above-described structure of the first electrical connection part 73, the second electrical connection part 74, and the pin facilitates a quick and stable connection between the connection end and the pin, and prevents the pin from coming out of the connection end through the push-in channel 732A.

[0123] In some embodiments of the sampling assembly, each pin also includes anti-detachment portions 623 and 633, which are disposed on corresponding mating sections 622 and 632 and spaced apart from the main body sections 621 and 631. The crimping portion 732 is located between the corresponding main body sections 621 and 631 and the anti-detachment portions 622 and 632.

[0124] The anti-detachment part facilitates the insertion pin to detach from the connection end along the extension direction of the receiving groove 731A.

[0125] The battery of this disclosure includes a battery cell and a sampling component of this disclosure. The sampling component is configured to collect parameters of the battery cell.

[0126] The battery of this embodiment has the advantages of the sampling component of this embodiment, which helps to improve the sampling performance of the battery, thereby facilitating the battery management system's safe management of the battery.

The electrode terminals 212 and 213 can be electrically connected to the cell assemblies 241 and 242 via adapter pieces 22 and 23 for outputting or inputting electrical energy into the battery cell.

[0133] like Figure 4 As shown, the circuit board 5 of the sampling assembly includes a circuit board body 51 and multiple sampling connection parts. The multiple sampling connection parts include a sampling connection part 52 for electrical connection with the sampling part 6, and may also include other sampling connection parts for connection with other sampling parts such as pressure sensors. For example, the multiple sampling connection parts may include a sampling connection part 53.

[0134] This disclosure will focus specifically on the connection between the sampling unit 6 and the sampling connection unit 52 via the electrical connector 7. The sampling unit 6 is a temperature sensor used to measure the temperature of individual battery cells.

[0135] like Figure 2 , Figures 4 to 11 As shown, the electrical connector 7 provided in this embodiment includes a housing, a first electrical connection portion 73, a second electrical connection portion 74, and a partition portion 75. The housing includes a shell 71 and a cover 72 that are interlocked. The first electrical connection portion 73, the second connection portion 74, and the partition portion 75 are all located inside the housing.

[0136] The first electrical connection 73 includes a first connection terminal 73A and a second connection terminal 73B electrically connected to the first connection terminal 73A. The second electrical connection 74 includes a third connection terminal 74A and a fourth connection terminal 74B electrically connected to the third connection terminal 74A. A separator 75, located between the first electrical connection 73 and the second electrical connection 74, is used to separate water droplets and reduces the risk of continuity between the first electrical connection 73 and the second electrical connection 74 due to condensation.

[0137] The outer casing includes a housing 71 and a cover 72. The housing 71 includes a bottom wall 711 and side walls 712 disposed on the outer periphery of the bottom wall 711. The outer casing is made of an insulating and waterproof material. The partition is also made of an insulating and waterproof material.

[0138] The first electrical connection portion 73 and the second electrical connection portion 74 are disposed on the bottom wall 711 of the housing 71. The cover 72 covers the housing 71 and is detachably connected to the housing 71 by a snap-fit ​​structure.

[0139] like Figures 5 to 11 As shown, the first electrical connection portion 73, the second electrical connection portion 74, and the partition portion 75 all extend along the length direction of the outer casing. The first electrical connection portion 73, the second electrical connection portion 74, and the partition portion 75 are arranged in parallel at intervals. The first electrical connection portion 73 and the second electrical connection portion 74 are generally arranged in a staggered manner. Figures 5 to 7 As shown, the separator 75 of the electrical connector 7 includes a first end 75A and a second end 75B disposed opposite to each other. The first connecting end 73A of the first electrical connection 73 is closer to the first end 75A of the separator 75 than the second connecting end 73B, and the second connecting end 73B of the first electrical connection 73 is closer to the second end 75B of the separator 75 than the first connecting end 73A. The third connecting end 74A of the second electrical connection 74 is closer to the first end 75A of the separator 75 than the fourth connecting end 74B, and the fourth connecting end 74B of the second electrical connection 74 is closer to the second end 75B of the separator 75 than the third connecting end 74A. The distance between the first connecting end 73A and the second end 75B is greater than the distance between the third connecting end 74A and the second end 75B, and the distance between the second connecting end 73B and the first end 75A is less than the distance between the fourth connecting end 74B and the first end 75A.

[0140] The partition 75 is divided into two parts, which are respectively disposed on the housing 71 and the cover 72. The connection between the partition 75 and the housing 71 and the cover 72 is a sealed connection. In this embodiment, the part of the partition 75 disposed on the housing 71 is integrally disposed with the housing 71, and the part of the partition 75 disposed on the cover 72 is integrally disposed with the cover 72.

[0141] like Figures 4 to 6 , Figure 11As shown, the partition 75 includes a first partition strip 751 and a second partition strip 752. The first partition strip 751 is integrally formed on the bottom wall 711 of the housing 71. The second partition strip 752 is integrally formed on the cover plate 721 of the cover 72. The end of the second partition strip 752 facing the first partition strip 751 and the end of the first partition strip 751 facing the second partition strip 752 are in a convex-concave fit. Figure 7 As shown, the main body 7511 of the first isolation strip 751 is a groove-shaped structure, and a mounting groove 751A is provided on it, as shown. Figure 11 As shown, the end of the second isolation strip 752 furthest from the cover 72 is sized to fit the mounting groove 751A. When the cover 72 is fastened onto the housing 71, the side of the second isolation strip 752 facing the housing 71 is inserted into the mounting groove 751A, forming a sealed connection between the first isolation strip 752 and the second isolation strip 751. This arrangement achieves a sealed connection between the partition 75 and the bottom wall 711 of the housing 71 and the cover 72.

[0142] like Figures 5 to 7 As shown, in order to allow the terminals of the sampling section 6 and the sampling connection section 52 to enter the housing of the electrical connector 7, through holes 711A, 711B, 711C and 711D are provided on the side wall of the housing 71 for connecting terminals that are electrically connected to the first connection terminal 73A, the second connection terminal 73B, the third connection terminal 74A and the fourth connection terminal 74B respectively.

[0143] The first connecting end 73A, the second connecting end 73B, the third connecting end 74A, and the fourth connecting end 74B are all crimping ends that connect to the pins. To achieve crimping between the pins and the crimping ends, each through hole 711A, 711B, 711C, and 711D is a groove formed in the side wall 712 of the housing 71, with the groove opening at the end furthest from the bottom wall 711. After the sampling section 6 and the sampling connection section 52 are connected to the first connecting end 73A, the second connecting end 73B, the third connecting end 74A, and the fourth connecting end 74B, the cover 72 can be placed on the housing 71. This installation reduces the operating space required when assembling the sampling section 6, the sampling connection section 52, and the electrical connection section 7.

[0144] like Figures 5 to 7 As shown, the first connecting end 73A, the second connecting end 73B, the third connecting end 74A and the fourth connecting end 74B of the second electrical connecting part 74 are spaced apart from the side wall 712 of the housing 71. The first end 75A and the second end 75B of the partition 75, which are arranged opposite to each other, are also spaced apart from the side wall 712.

[0145] The snap-fit ​​structure connecting the housing 71 and the cover 72 includes a first snap-fit ​​part and a second snap-fit ​​part. The first snap-fit ​​part is a latch 721A provided on the cover plate 721 of the cover 72. The second snap-fit ​​part is a hook 76 provided on the bottom wall 711 of the housing 71 and located within the gap, which engages with the latch 721A.

[0146] like Figures 5 to 11 As shown, the first electrical connection portion 73 includes a groove 731 and a crimping portion 732. The groove 731 includes a receiving groove 731A for accommodating a connection terminal. The crimping portion 732 is connected to the opening side of the receiving groove 731A at the end of the groove 731 in the extending direction, and includes a crimping channel 732A communicating with the opening of the receiving groove 731A. In a cross-section perpendicular to the extending direction of the groove 731, the minimum passage size of the crimping channel 732A is smaller than the opening size of the receiving groove 731A. In a cross-section perpendicular to the extending direction of the groove 731, from the side away from the receiving groove 731A to the side closer to the receiving groove 731A, the size of the crimping channel 732A first gradually decreases to the minimum passage size and then gradually increases. The crimping portion 732 includes a first crimp connector 7321 and a second crimp connector 7322, and the crimping channel 732A is formed between the first crimp connector 7321 and the second crimp connector 7322.

[0147] The first connection end 73A and the second connection end 73B of the first electrical connection part 73 are respectively provided with a crimping part, so that the first connection end 73A and the second connection end 73B each form a crimping end.

[0148] The second electrical connection portion 74 has the same structure as the first electrical connection portion 73, and the structure of the first electrical connection portion can be referred to.

[0149] like Figure 5 , Figure 6 , Figure 9 and Figure 10 As shown, the sampling component 6 includes a sampling section 61 and a first sampling component connection terminal 62 and a second sampling component connection terminal 63 connected to the sampling section 61.

[0150] like Figure 5 and Figure 6 As shown, the circuit board 5 includes a circuit board body 51 and a sampling connection portion 52 connected to the circuit board body 51. The sampling connection portion 52 includes a first circuit board connection terminal 521 and a second circuit board connection terminal 522. The first sampling component connection terminal 521 is electrically connected to the first connection terminal 73A of the first electrical connection portion 73. The second sampling component connection terminal 521 is electrically connected to the second connection terminal 73B of the first electrical connection portion 73. The second circuit board connection terminal 522 is electrically connected to the fourth connection terminal 74B of the second electrical connection portion 74.

[0151] The first sampling component connection terminal 62, the second sampling component connection terminal 63, the first circuit board connection terminal 521, and the second circuit board connection terminal 522 each include a pin. The first connection end 73A, the second connection end 73B, the third connection end 74A, and the fourth connection end 74B are all crimped ends that connect to the corresponding pins.

[0152] To accommodate the misaligned arrangement of the first electrical connection portion 73 and the second electrical connection portion 74, the distance between the insertion end face of the pin of the first sampling component connection terminal 62 and the sampling portion 61 is less than the distance between the insertion end face of the pin of the second sampling component connection terminal 63 and the sampling portion 61. The distance between the insertion end face of the pin of the first circuit board connection terminal 521 and the circuit board body 51 is greater than the distance between the insertion end face of the pin of the second circuit board connection terminal 522 and the circuit board body 51.

[0153] Each pin of the first sampling component connection terminal 62, the second sampling component connection terminal 63, the first circuit board connection terminal 521, and the second circuit board connection terminal 522 includes a main body segment 621, 631, 5211, and 5221 and a mating segment 622, 632, 5212, and 5222. Each mating segment 622, 632, 5212, and 5222 mates with a corresponding receiving groove, such as receiving groove 731A, and a crimping part, such as crimping part 732. The main body segments 621, 631, 5211, and 5221 connect to the corresponding mating segments 622, 632, 5212, and 5222 and the sampling component 61 or the circuit board body 51.

[0154] like Figure 9 and Figure 10 As shown, in some embodiments, each pin of the first sampling component connection terminal 62, the second sampling component connection terminal 63, the first circuit board connection terminal 521, and the second circuit board connection terminal 522 further includes an anti-detachment portion. For example, the first sampling component connection terminal 62 has an anti-detachment portion 623, and the second sampling component connection terminal 63 has an anti-detachment portion 633. The anti-detachment portion is disposed on the corresponding mating section, such as the anti-detachment portion 623 being disposed on the mating section 622, and the anti-detachment portion 633 being disposed on the mating section 632, and is spaced apart from the corresponding main body section, such as the anti-detachment portion 623 being disposed between the main body section 621, and the anti-detachment portion 633 being disposed between the main body section 631. The crimping portion is located between the corresponding main body section and the anti-detachment portion.

[0155] like Figure 9 and Figure 10 As shown, the anti-detachment part can be, for example, a protruding ring provided on the mating section, or multiple protrusions arranged circumferentially along the mating section.

[0156] In this embodiment of the disclosure, the housing 71 and its components of each electrical connector 7, as well as the cover 72 and its components, are injection molded parts. Each terminal is also embedded in the corresponding injection molded part to facilitate processing and assembly, better realize the insulation and waterproof performance of the electrical connector itself, and strengthen the separation function of adjacent terminals.

[0157] As described above, the electrical connector and sampling assembly of this embodiment help prevent short circuits between adjacent terminals of the electrical connector caused by condensation in high-temperature and high-humidity environments. The signal collected by the temperature sensor of the sampling unit 6 is transmitted to the BMS board through the electrical connector 7, circuit board 5, and connector 8, achieving temperature sampling while also providing easy disassembly and waterproof functionality.

[0158] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and not to limit them; although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this disclosure or equivalent substitutions can be made to some technical features, all of which should be covered within the scope of the technical solutions claimed in this disclosure.
