[0005] In the above scheme, the sampling wire is fixed by the biting portion to improve the more firm connection between the sampling wire and the conductive terminal, and reduce the probability of relative movement between the sampling wire and the conductive terminal under a vibration environment or external force interference, so that the first conductive contact portion can maintain electrical connection with the sampling wire, reduce the probability of a circuit breaker between the conductive terminal and the sampling wire, and thus improve the stability of data transmission.

[0024] In some embodiments, the shell assembly is provided with a slot communicating with the cavity, and the conductive terminal further comprises an elastic clip connected with the main body, and at least a portion of the elastic clip is inserted into the slot.

[0065] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0066] With the rapid development of electric vehicles, the requirements for battery performance and stability are getting higher and higher. Therefore, it is usually necessary to collect the state parameters of the battery and manage the battery based on the state parameters, such as the voltage, temperature and other data of the multiple battery cells that make up the battery. For example, a temperature sensor can be used to collect data such as the temperature of the battery, and a flexible flat cable (FFC) electrically connected to the temperature sensor can be used to transmit the battery temperature data signal to the thermal management system in the form of an electrical signal, so that the thermal management system can manage the battery temperature.

[0067] In existing equipment, the flexible flat cable is plugged into the connector and abutted against the conductive terminals, and the temperature sensor is indirectly electrically connected to the flexible flat cable. This facilitates the rapid removal of the flexible flat cable when the temperature sensor fails, so as to facilitate the rapid replacement of the temperature sensor. However, in a high-speed vibration environment, the conductive terminals are affected by the vibration, and the conductive terminals in the connector are easily separated from the conductive connectors of the flexible flat cable, resulting in a short circuit, thereby interrupting the temperature data transmission of the battery cell, seriously affecting the stability of the signal transmission.

[0068] Based on the above considerations, Figure 5 and Figure 6As shown, the present application proposes a connector 500, by respectively providing a first conductive contact portion 522 and a bite portion 523 on a conductive terminal 520, utilizing the first conductive contact portion 522 to be conductively connected to a sampling wire 600 to achieve data signal transmission, utilizing the bite portion 523 to bite and fix the sampling wire 600, thereby reducing the probability of relative movement between the sampling wire 600 and the conductive terminal 520 under a vibration environment or external force interference, thereby enabling the first conductive contact portion 522 to maintain electrical connection with the sampling wire 600, reducing the probability of a circuit breaker between the conductive terminal 520 and the sampling wire 600, and improving the stability of data transmission.

[0069] The battery disclosed in the embodiment of the present application can be used in, but not limited to, electric devices such as vehicles, ships or aircraft.

[0086] Conductive connection can be understood as two interconnected components being able to conduct electricity. The conductive connection defined in this embodiment enables the connector 500 to transmit electrical signals through the sampling wire 600.

[0087] The conductive terminal 520 is a conductor. In this embodiment, the conductive terminal 520 is integrally formed by a metal plate-like member through cutting, stamping, bending and other processes. The main body 521 is a rectangular cylindrical structure. The first conductive contact portion 522 and the bite portion 523 are arranged at one end of the length direction of the main body 521. Along the length direction of the main body 521, the first conductive contact portion 522 and the bite portion 523 are located between the main body 521 and the first plug interface 502, so that the first conductive contact portion 522 and the bite portion 523 are respectively arranged opposite to the first plug interface 502. After the contact end of the sampling wire 600 is inserted into the accommodating cavity through the first plug interface 502, it is conductively connected to the first conductive contact portion 522 and is fixed by the bite portion 523.

[0088] The bite portion 523 can apply a pressing force to the sampling wire 600 so as to firmly bite and fix the sampling wire 600 to the conductive terminal 520. In some embodiments, the pressing force applied by the bite portion 523 to the sampling wire 600 can be an elastic force applied by the bite portion 523 itself to the sampling wire 600. In other embodiments, the bite portion 523 can also be fixed by other external components to apply pressure to the sampling wire 600 to bite and fix the sampling wire 600.

[0089] The bite fixation can be understood as that after the bite portion 523 is pressed against the sampling wire 600, at least the sampling wire 600 is deformed under the extrusion effect, so that part of the contour of the bite portion 523 is pressed into the groove or through hole formed by the deformation of the sampling wire 600, so that a misaligned bite is formed between the contours of the bite portion 523 and the sampling wire 600.

[0090] The present application fixes the sampling wire 600 by biting the biting portion 523 to improve the more secure connection between the sampling wire 600 and the conductive terminal 520, and reduce the probability of relative movement between the sampling wire 600 and the conductive terminal 520 under a vibration environment or external force interference, so that the first conductive contact portion 522 can maintain electrical connection with the sampling wire 600, reduce the probability of a circuit breaker between the conductive terminal 520 and the sampling wire 600, and improve the stability of data transmission.

[0091] In some embodiments, Figure 6 and Figure 8 As shown, the bite portion 523 has at least one sawtooth structure 5231. Along the first direction, the bite portion 523 can be bent and deformed relative to the main body 521, so that the bite portion 523 can move between a first position and a second position. The first direction forms an angle with the direction of the first plug port 502. In the first position, the bite portion 523 is used to separate from the sampling wire 600. In the second position, the bite portion 523 is used to abut against the sampling wire 600, and at least part of the sawtooth structure 5231 penetrates the sampling wire 600.

[0092] The area where the bite portion 523 is connected to the main body 521 can be bent under the action of external force, so that the relative position of the bite portion 523 and the main body 521 changes, and then the relative position of the bite portion 523 and the sampling wire 600 inserted into the cavity 501 can be changed. In some embodiments, the bite portion 523 is manually applied with a pulling force, so that the bite portion 523 is bent relative to the main body 521 and moved to the first position, so as to facilitate the insertion of the sampling wire 600 into the cavity 501. In the absence of external force, the bite portion 523 elastically recovers under the action of its own elastic force, moves from the first position to the second position, and bites and fixes the sampling wire 600. In other embodiments, in the absence of external force, the bite portion 523 is located at the first position, so as to facilitate the insertion of the sampling wire 600 into the cavity 501. When an external device applies pressure to the bite portion 523, the bite portion 523 is bent relative to the main body 521 and moves to the second position, and bites and fixes the sampling wire 600.

[0093] The sawtooth structure 5231 is sawtooth-shaped, and the tooth tip of the sawtooth structure 5231 is used to face the sampling wire 600. When the sawtooth structure 5231 abuts against the sampling wire 600, the tooth tip of the sawtooth structure 5231 can penetrate the sampling wire 600 to bite and fix the sampling wire 600.

[0094] In this embodiment, by providing the sawtooth structure 5231, when the bite portion 523 bites and fixes the sampling wire 600, at least a portion of the sawtooth structure 5231 penetrates the sampling wire 600, thereby more firmly connecting the sampling wire 600 to the conductive terminal 520, and reducing the probability of the sampling wire 600 moving relative to the conductive terminal 520 under vibration or other environments.

[0095] In some embodiments, Figure 5 and Figure 6 As shown, the shell assembly 510 includes a shell 511 and a driving member 512. The shell 511 defines a cavity 501. The driving member 512 is movably connected to the shell 511 and abuts against the engaging portion 523. When the driving member 512 moves relative to the shell 511, the engaging portion 523 moves between the first position and the second position under the pressure of the driving member 512.

[0096] The driving member 512 is movably connected to the housing 511, so that the driving member 512 can move relative to the housing 511 to change the relative position of the driving member 512 and the housing 511. The driving member 512 can move relative to the housing 511 in a variety of ways, for example, the driving member 512 rotates relative to the housing 511, or the driving member 512 slides relative to the housing 511, etc. The driving member 512 and the housing 511 have a variety of optional connection methods. For example, in some embodiments, the housing 511 is provided with a threaded hole extending in the first direction, and the driving member 512 is a road bolt threadedly matched with the threaded hole. The driving member 512 is rotatably arranged in the threaded hole, and one end of the driving member 512 extends into the cavity 501 and abuts against the bite portion 523. By rotating the driving member 512, the driving member 512 moves relative to the housing 511 along the first direction, and applies pressure to the bite portion 523, so that the bite portion 523 bends relative to the main body 521 and moves from the first position to the second position and bites and fixes the sampling wire 600. It can be understood that the active connection method of the driving member 512 and the housing 511 can also be set to other methods, which will not be repeated here.

[0097] In this embodiment, the pressing action of the driving member 512 is utilized to move the engaging portion 523 between the first position and the second position, thereby enabling the engaging portion 523 and the sampling wire 600 to switch between a separated state and an engaged state, thereby realizing a detachable connection between the sampling wire 600 and the connector 500, making the connector 500 replaceable, and improving the compatibility of the connector 500.

[0098] In some embodiments, Figures 6 to 8As shown, the shell 511 is provided with an avoidance groove 5111 connected to the cavity 501, and the avoidance groove 5111 is arranged opposite to the bite portion 523; the driving member 512 is rotatably connected to the shell 511 and is provided with a pressing portion 5121 matching the bite portion 523, and the driving member 512 can be flipped relative to the shell 511 between an open position and a closed position. In the open position, the pressing portion 5121 is located outside the cavity 501, and the bite portion 523 is located in the first position. In the closed position, the pressing portion 5121 extends into the cavity 501 through the avoidance groove 5111 and presses against the bite portion 523, so that the bite portion 523 moves to the second position.

[0099] The driving member 512 is in a cover plate-like structure, with rotating shafts protruding from both sides of the driving member 512 , and the housing 511 is provided with an axial hole rotatably matched with the rotating shaft, so that the driving member 512 can be flipped relative to the housing 511 .

[0100] In this embodiment, the position of the engaging portion 523 can be quickly changed by flipping the driving member 512 , so that the engaging portion 523 and the sampling wire 600 can be switched between a separated state and an engaged state, thereby improving the convenience of installing or removing the sampling wire 600 in the connector 500 .

[0101] In some embodiments, Fig.10 As shown, the housing 511 is provided with a receiving groove 5112 for receiving the driving member 512 , and the contour of the receiving groove 5112 matches the contour of the driving member 512 . In the closed position, the driving member 512 is received in the receiving groove 5112 .

[0102] In this embodiment, the driving member 512 is received in the receiving groove 5112 to reduce the probability of the driving member 512 contacting external objects in the closed position, and the probability of the driving member 512 flipping due to external force factors such as accidental touch is reduced, so that the bite portion 523 can bite and fix the sampling wire 600 on the conductive terminal 520 more firmly.

[0103] In some embodiments, Fig.10 As shown, one of the driving member 512 and the housing 511 is provided with a locking groove 5113, and the other is provided with a locking buckle 5122 that is snap-fitted with the locking groove 5113. In the closed position, the locking buckle 5122 is inserted into the locking groove 5113.

[0104] The locking groove 5113 is arranged on the inner wall of the accommodating groove 5112, and the locking buckle 5122 is protruded on the two side walls of the driving member 512. The locking buckle 5122 is also provided with an inclined surface. During the flipping process of the driving member 512, the inclined surface has a guiding function, so that the locking buckle 5122 can be smoothly inserted into the locking groove 5113.

[0105] In this embodiment, the locking groove 5113 cooperates with the locking buckle 5122 to make the driving member 512 more firmly connected to the housing 511 in the closed position, thereby reducing the probability of the driving member 512 flipping due to external forces such as accidental touch and vibration, so that the bite portion 523 can bite and fix the sampling wire 600 on the conductive terminal 520 more firmly.

[0106] In some embodiments, Fig.10 As shown, the housing 511 is further provided with a disassembly groove 5114 communicating with the accommodating groove 5112 , and a portion of the edge area of ​​the driving member 512 is exposed outside the disassembly groove 5114 .

[0107] In this embodiment, the disassembly groove 5114 is provided so that a tool can be used to abut against the edge of the driving member 512 through the disassembly groove 5114 and pry the driving member 512 open, thereby reducing the difficulty of disassembling the sampling wire 600 .

[0108] In some embodiments, please combine Figure 8 , Fig.11 and Fig.12 As shown, the conductive terminal 520 further includes a support arm 524 connected to the main body 521 . Along the first direction, the support arm 524 is arranged opposite to the first conductive contact portion 522 . The support arm 524 and the bite portion 523 are used to clamp the sampling wire 600 together.

[0109] The supporting arm 524 and the first conductive contact portion 522 are disposed opposite to each other, which means that along the first direction, the supporting arm 524 and the first conductive contact portion 522 are at least partially overlapped.

[0110] In this embodiment, the support arm 524 is used to support the sampling wire 600, and the support arm 524 and the first conductive contact portion 522 jointly clamp the sampling wire 600, so that the sampling wire 600 is more firmly connected to the conductive terminal 520, and the probability of relative movement between the sampling wire 600 and the conductive terminal 520 under external force or vibration environment is further reduced, so as to maintain the stability of the electrical connection between the conductive terminal 520 and the sampling wire 600.

[0111] In some embodiments, please combine Figure 8 , Fig.11 and Fig.12 As shown, the support arm 524 includes a main body 5241 and two side portions 5242 , the two side portions 5242 are arranged at both ends of the main body 5241 and form a groove structure with the main body 5241 , the sawtooth structure 5231 is arranged opposite to the side portion 5242 , and the first conductive contact portion 522 is arranged opposite to the main body 5241 .

[0112] The support arm 524 is in a rectangular plate shape, and is folded along two opposite long sides of the support arm 524 toward one side of the bite portion 523 to form two side portions 5242 respectively.

[0113] In this embodiment, the side portion 5242 cooperates with the sawtooth structure 5231 to bite and fix the sampling wire 600 , and the first conductive contact portion 522 cooperates with the body portion 5241 to press the sampling wire 600 and electrically connect with the sampling wire 600 .

[0114] In some embodiments, please combine Figure 6 and Figure 8 As shown, the first conductive contact portion 522 is a bent cantilever structure and can be elastically deformed along a first direction. The first conductive contact portion 522 is also used to apply elastic force to the sampling wire 600 along the first direction. The first direction forms an angle with the direction of the first plug port 502 .

[0115] The first conductive contact portion 522 is formed by bending a long strip of plate-like member in the reverse direction, and includes a connecting section 5221 and a cantilever section 5222. The connecting section 5221 is connected to the main body 521, and the cantilever section 5222 is connected to one end of the connecting section 5221 away from the main body 521. The cantilever section 5222 is bent in the reverse direction toward the main body 521 relative to the connecting section 5221, and the cantilever section 5222 is used to abut against and be conductively connected to the sampling wire 600.

[0116] In this embodiment, when the sampling wire 600 vibrates relative to the conductive terminal 520 in a high-speed vibration environment, the elastic deformation performance of the first conductive contact portion 522 is utilized to ensure that the first conductive contact portion 522 always maintains a state of pressing the sampling wire 600, thereby improving the stability of the conductive connection between the conductive terminal 520 and the sampling wire 600.

[0117] In some embodiments, please combine Figure 6 and Figure 8 As shown, the housing assembly 510 is provided with a slot 5115 communicating with the cavity 501 , and the conductive terminal 520 further includes an elastic buckle 525 connected to the main body 521 , and at least a portion of the elastic buckle 525 is inserted into the slot 5115 .

[0118] The elastic buckle 525 is cantilevered, and the free end of the elastic buckle 525 faces the direction of the first plug interface 502, and the elastic buckle 525 extends obliquely to the side away from the main body 521. When the conductive terminal 520 is installed in the housing assembly 510, the conductive terminal 520 is inserted into the cavity 501 from the first plug interface 502 until the elastic buckle 525 is inserted into the slot 5115. In this way, when the conductive terminal 520 moves relative to the housing assembly 510 toward one end of the first plug interface 502 under a high-speed vibration environment, the free end of the elastic buckle 525 abuts against the inner wall of the slot 5115, thereby preventing the conductive terminal 520 from continuing to move, thereby reducing the probability of the conductive terminal 520 coming off the housing assembly 510 under a high-speed vibration environment.

[0119] In this embodiment, the elastic buckle 525 is engaged with the slot 5115 to improve the stability of the connection between the conductive terminal 520 and the housing assembly 510 and reduce the probability of the conductive terminal 520 falling out of the cavity 501 under high-speed vibration conditions.

[0120] In some embodiments, please combine Figure 6 , Figure 8 and Fig.10 As shown, the shell assembly 510 also defines a second plug interface 503 connected to the cavity 501, and the conductive terminal 520 also includes a second conductive contact portion 526 connected to the main body 521. The first conductive contact portion 522 and the bite portion 523 are arranged opposite to the first plug interface 502, and the second conductive contact portion 526 is arranged opposite to the second plug interface 503; wherein the second plug interface 503 is used to install a data acquisition device and allow the pins of the data acquisition device to be inserted into the cavity 501, and the second conductive contact portion 526 is used to be conductively connected to the pins.

[0121] The second plug-in port 503 and the first plug-in port 502 are respectively disposed on two opposite side walls of the housing 511 . The first plug-in port 502 and the second plug-in port 503 are respectively located at two ends of the conductive terminal 520 in the length direction.

[0122] The second conductive contact portion 526 is disposed between the first plug interface 502 and the first conductive contact portion 522 , so that the pin of the data acquisition device can be directly conductively connected to the second conductive contact portion 526 when inserted into the cavity 501 through the second plug interface 503 .

[0123] The second plug-in port 503 is also used to install a data acquisition device, which includes but is not limited to a temperature sensor.

[0124] The data acquisition device is detachably connected to the connector 500 via the second plug interface 503. Therefore, when a failure occurs in the data acquisition device, the data acquisition device can be removed from the connector 500 at any time, so that the connector 500 has both replaceability and compatibility.

[0125] In this embodiment, the second plug interface 503 serves as the installation position of the data acquisition device, so that the conductive terminal 520 in the connector 500 can also be conductively connected to the pin of the data acquisition device, so that the connector 500 can be electrically connected to the data acquisition device and the sampling wire 600 respectively, so that the connector 500 has the function of transmitting the data information collected by the data acquisition device to the sampling wire 600, and the connector 500 can be compatible with different data acquisition devices, thereby improving the application range of the connector 500.

[0126] In some embodiments, Figure 8 As shown, the second conductive contact portion 526 is a cantilever structure and can be elastically deformed along the second direction, and the second conductive contact portion 526 is also used to apply elastic force to the pin along the second direction, and the second direction is at an angle to the direction of the second plug interface 503. The second direction is parallel to the first direction.

[0127] The free end of the second conductive contact portion 526 faces the direction of the first plug interface 502, and the second conductive contact portion 526 extends obliquely toward the main body 521, so that when the pin of the data acquisition device is inserted into the cavity 501, the second conductive contact portion 526 and the inner wall of one side of the main body 521 jointly clamp the pin, so that the second conductive contact portion 526 is conductively connected to the pin.

[0128] In this embodiment, when the pin of the data acquisition device vibrates relative to the conductive terminal 520 in a high-speed vibration environment, the elastic deformation performance of the second conductive contact portion 526 is utilized to ensure that the second conductive contact portion 526 always maintains a state of pressing the pin, thereby improving the stability of the conductive connection between the conductive terminal 520 and the pin.

[0129] In some embodiments, please combine Fig. 9 and Fig.12 As shown, the connector 500 includes at least two conductive terminals 520 , and a partition 5116 is further provided in the cavity 501 . The partition 5116 is used to isolate adjacent conductive terminals 520 .

[0130] The separator 5116 is used to isolate adjacent conductive terminals 520 , separate the conductive terminals 520 into different areas, and reduce the probability of adjacent conductive terminals 520 contacting each other and causing a short circuit.

[0132] In the second aspect, the present application provides a battery, which includes a battery cell, a connector 500, a data acquisition device and a sampling wire 600. The connector 500 is arranged on the battery cell, and the sampling wire 600 is used to transmit the state parameters of the battery cell. The sampling wire 600 is plugged into the first plug interface 502 in the connector 500 and is conductively connected to the first conductive contact in the connector 500.

The data acquisition device is plugged into the second plug interface 503 in the connector 500 , and the pins of the data acquisition device are conductively connected to the second conductive contact portion 526 in the connector 500 .

[0137] The conductive terminal 520 is a conductor, and the conductive terminal 520 is integrally formed by a metal plate-like part through cutting, stamping, bending and other processes. The conductive terminal 520 includes a main body 521 and a first conductive contact part 522, a second conductive contact part 526, a bite part 523, a support arm 524 and an elastic buckle 525 connected to the main body 521. The main body 521 is a rectangular cylindrical structure, and the first conductive contact part 522 and the bite part 523 are arranged at one end of the length direction of the main body 521.

[0138] Furthermore, after the sampling wire 600 is inserted into the cavity 501 through the first plug port 502 , the sampling wire 600 is still between the support arm 524 and the bite portion 523 . The bite portion 523 has a plurality of sawtooth structures 5231 at one end facing the support arm 524 . The sawtooth structures 5231 are used to bite and fix the sampling wire 600 .

[0139] Specifically, the driving member 512 is in a cover plate-like structure, and a rotating shaft is protruded on both sides of the driving member 512. The shell 511 is provided with an axial hole that rotates with the rotating shaft, so that the driving member 512 can be flipped relative to the shell 511 between the open position and the closed position. The driving member 512 is provided with a pressing portion 5121 that cooperates with the bite portion 523, and the shell 511 is provided with an avoidance groove 5111 that is connected to the cavity 501. The avoidance groove 5111 is connected with the bite portion 523. For the setting, in the open position, the pressing portion 5121 is located outside the cavity 501, and the bite portion 523 is located in the first position. In the closed position, the pressing portion 5121 extends into the cavity 501 through the avoidance groove 5111 and presses the bite portion 523, so that the bite portion 523 moves to the second position, the sawtooth structure 5231 is against the sampling wire 600, and the tooth tip of the sawtooth structure 5231 pierces the sampling wire 600 to bite and fix the sampling wire 600.

The housing 511 is also provided with a disassembly groove 5114 communicating with the receiving groove 5112. Part of the edge area of ​​the driving member 512 is exposed in the disassembly groove 5114. A tool is used to abut against the edge of the driving member 512 through the disassembly groove 5114 and pry the driving member 512 open, thereby reducing the difficulty of disassembling the sampling wire 600.
