Abstract
Description
Technical Field
[0001] This application relates to the field of battery technologies, and more particularly, to an electrical connector, a battery, and an electrical device using the same. Background Art
[0002] Batteries are widely used in electronic devices, such as mobile phones, laptop computers, battery-powered vehicles, electric vehicles, electric airplanes, electric ships, electric toy cars, electric toy ships, electric toy airplanes, and power tools, etc.
[0003] In a battery, an electrical connector is required to connect the battery and the electrical device. The wire harness connected to the electrical connector is susceptible to external magnetic field interference, which affects the working performance of the wire harness and further affects the working stability of the entire battery. Summary of the Invention
[0004] This application provides an electrical connector that can reduce the interference of the wire harness by an external magnetic field and improve the working stability of the battery.
[0005] In a first aspect, an embodiment of this application provides an electrical connector, including: a connector body for connecting a wire harness; a magnetic shielding member connected to the connector body and provided with a wire passing hole for the wire harness to pass through. By providing a magnetic shielding member on the connector body, a shielding magnetic field is formed by the magnetic shielding member to absorb and guide an external electromagnetic field, thereby transferring or weakening the external magnetic field to reduce the influence on the wire harness, which helps to stabilize the working performance of the wire harness and further improves the working stability of the entire battery.
[0006] In some embodiments of this application, the magnetic shielding member includes a first split body and a second split body. The first split body is provided with a first wire groove, and the second split body is provided with a second wire groove. The first wire groove and the second wire groove enclose the wire passing hole. By designing the magnetic shielding member as the mutually connected first split body and second split body, during assembly, the first split body can be first connected to the connector body, then the wire harness is connected to the connector body, and the wire harness is located in the first wire groove. Finally, the first split body and the second split body are docked so that the wire harness is located in the wire passing hole formed by the first wire groove and the second wire groove, which is beneficial to the electrical connector to connect the wire harness and facilitates the assembly operation of the wire harness, improving the assembly efficiency.
[0007] In some embodiments of this application, the first split body and the second split body are connected in a detachable manner. By detachably connecting the first split body and the second split body, while facilitating assembly, it is also possible to facilitate the disassembly of the first split body and the second split body to facilitate the maintenance of the wire harness.
[0008] In some embodiments of the present application, the first split body and the second split body are connected by plugging, snap connection, bonding or magnetic attraction connection. The connection between the first split body and the second split body is realized by means such as plugging, snap connection, bonding or magnetic attraction. The structure is simple, and it is easy to assemble and disassemble the first split body and the second split body. At the same time, the manufacturing cost is relatively low.
[0009] In some embodiments of the present application, the magnetic shielding member is annular. The magnetic shielding member has opposite annular inner wall surfaces and annular outer wall surfaces in the radial direction. The annular inner wall surfaces enclose the wire passing holes. By designing the magnetic shielding member as an annular shape, the annular structure can make the magnetic field of the wire harness better concentrated, reduce the magnetic field loss, and improve the utilization rate of the magnetic field. At the same time, the annular structure can match the outer protective layer of the wire harness, so that the annular inner wall surface of the magnetic shielding member is close to or even wraps the wire harness, improving the shielding and protection effect on the wire harness.
[0010] In some embodiments of the present application, the electrical connector further includes a connecting member. The connecting member includes opposite first end and second end. The first end is connected to the connector body, and the second end is connected to the magnetic shielding member. The connecting member is provided with a wire passing channel for the wire harness to pass through. The wire passing channel extends from the first end to the second end and is communicated with the wire passing hole. By configuring the connecting member, it is convenient to connect the relatively large connector body and the relatively small magnetic shielding member. At the same time, the wire passing channel can also play a certain role in protecting and restricting the wire harness.
[0011] In some embodiments of the present application, the connecting member and the connector body are connected in a detachable manner. By designing the connecting member and the connector body to be detachably connected, it is beneficial for assembly and can also facilitate the disassembly of the connecting member and the connector body to facilitate the maintenance of the wire harness inside the connecting member.
[0012] In some embodiments of the present application, the connecting member is provided with either a first snap or a first slot, and the connector body is provided with the other of the first snap or the first slot. The first snap and the first slot are snap-connected. The connecting member and the connector are detachably connected by the first snap and the first slot. The structure is simple, and it is easy to assemble and disassemble and repair the two.
[0013] In some embodiments of the present application, from the first end to the second end, the size of the connecting member gradually decreases in a first direction, and the first direction intersects with the direction from the first end to the second end. By designing the size of the connecting member to gradually decrease from the first end to the second end, the size of the second end and the magnetic shielding member in the first direction is smaller than that of the first end, and the size of the magnetic shielding member can also be adaptively reduced. Therefore, the consumables and the occupied space of the connecting member and the magnetic shielding member can be reduced.
[0014] In some embodiments of the present application, from the first end to the second end, the size of the wiring channel gradually decreases in the first direction. By designing the size of the wiring channel to gradually decrease from the first end to the second end, the internal contour of the wiring channel is similar to the shape of the internal wire harness, and the internal wire harness can be better constrained and protected.
[0015] In some embodiments of the present application, the connecting member is provided with an opening communicating with the wiring channel, and the opening extends from the first end to the second end. By providing the opening, the wire harness can be conveniently installed in the wiring channel directly through the opening and connected to the connector body, improving the assembly efficiency of the electrical connector and the wire harness.
[0016] In some embodiments of the present application, the magnetic shielding member includes a first split body and a second split body. The first split body is provided with a first wire passing groove, and the second split body is provided with a second wire passing groove. The first wire passing groove and the second wire passing groove enclose the wiring hole. The connecting member is connected to the first split body, and the wiring channel is communicated with the first wire passing groove. By communicating the wiring channel with the first wire passing groove, the wire harness can be directly installed in the connecting member and the first wire passing groove through the opening and the first wire passing groove, and then the second split body is connected to the first split body to realize the binding and electromagnetic shielding of the wire harness, facilitating the installation of the wire harness and improving the assembly efficiency of the wire harness.
[0017] In a second aspect, an embodiment of the present application further provides a battery, which includes the electrical connector according to any one of the above technical solutions, and one end of the electrical connector is used to connect the wire harness of the battery.
[0018] In a third aspect, an embodiment of the present application further provides an electrical device, which includes the battery according to the above technical solution, and the battery is used to provide electrical energy. Description of the Drawings

[0049] Next, the embodiments of the present application will be described in detail.
[0050] Currently, 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 plants, but also widely used in electric transportation such as electric bicycles, electric motorcycles, and electric vehicles, as well as in multiple fields such as military equipment and aerospace. With the continuous expansion of the application fields of power batteries, the market demand is also constantly increasing.
[0051] Taking an electric device as a vehicle as an example, the power battery needs to be electrically connected to the vehicle through an electrical connector. For example, a low-voltage wire harness connecting the battery management system is connected to the vehicle through an electrical connector. However, since there are high-voltage wire harnesses in the battery and the electric device, the magnetic field of the high-voltage wire harness will generate magnetic interference on the low-voltage wire harness, which may cause the signals transmitted in the low-voltage wire harness to be affected, affecting the monitoring and control of the battery state by the battery management system, and even causing the entire battery to malfunction, affecting the stability and reliability of the battery.
[0052] Therefore, how to reduce the interference of external magnetic fields on wire harnesses to improve the working stability of wire harnesses is an important topic in the research and development of batteries and their related components.
[0053] In view of this, the present application provides a technical solution, which protects the wire harness by adding a magnetic shielding member to the electrical connector, and uses the magnetic shielding member to absorb and conduct the external magnetic field, so as to transfer or weaken the external magnetic field to reduce the influence on the internal wire harness.
[0054] For the convenience of description in the following embodiments, an electric device is taken as a vehicle as an example for description.
[0055] Figure 1 It is a schematic structural diagram of a vehicle provided in some embodiments of the present application.
[0056] Combined with the attached Figure 1 As shown in the figure, the vehicle 1000 can be a fuel vehicle, a gas vehicle or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. A battery 100 is provided inside the vehicle 1000, and the battery 100 can be arranged at the bottom, head or tail of the vehicle 1000. The battery 100 can be used to supply power to the vehicle 1000. For example, the battery 100 can be used as the operating power source of the vehicle 1000. The vehicle 1000 can also include a controller 200 and a motor 300. The controller 200 is used to control the battery 100 to supply power to the motor 300. For example, it is used for the working power requirements during the start, navigation and driving of the vehicle 1000.
[0057] In some embodiments of the present application, the battery 100 can not only be used as the operating power source of the vehicle 1000, but also be used as the driving power source of the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.
[0058] Figure 2 It is an exploded view of a battery provided in some embodiments of the present application.
[0059] Combined with the attached Figure 2As shown in the figure, the battery 100 includes a box body 10 and battery cells 20, and the battery cells 20 are accommodated in the box body 10. Among them, the box body 10 is used to provide an accommodation space for the battery cells 20, and the box body 10 can adopt various structures. In some embodiments, the box body 10 may include a first part 11 and a second part 12. The first part 11 and the second part 12 cover each other, and the first part 11 and the second part 12 jointly define an accommodation space for accommodating the battery cells 20. The second part 12 may be a hollow structure with one end open, and the first part 11 may be a plate-like structure. The first part 11 covers the open side of the second part 12 so that the first part 11 and the second part 12 jointly define an accommodation space; the first part 11 and the second part 12 may also both be hollow structures with one side open, and the open side of the first part 11 covers the open side of the second part 12. Of course, the box body 10 formed by the first part 11 and the second part 12 can be of various shapes, such as a cylinder, a cuboid, etc.
[0060] In the battery 100, there may be multiple battery cells 20, and the multiple battery cells 20 can be connected in series, in parallel, or in a mixed connection. A mixed connection means that there are both series and parallel connections among the multiple battery cells 20. The multiple battery cells 20 can be directly connected in series, in parallel, or in a mixed connection together, and then the whole formed by the multiple battery cells 20 is accommodated in the box body 10; of course, the battery 100 can also be that multiple battery cells 20 are first connected in series, in parallel, or in a mixed connection to form a battery module form, and then multiple battery modules are connected in series, in parallel, or in a mixed connection to form a whole and are accommodated in the box body 10. The battery 100 may further include other structures. For example, the battery 100 may further include a busbar component for realizing the electrical connection among the multiple battery cells 20.
[0061] Among them, each battery cell 20 can be a secondary battery or a primary battery; it can also be a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited thereto. The battery cell 20 can be in the shape of a cylinder, a flat body, a cuboid, or other shapes, etc.
[0062] In addition, the battery 100 further includes a battery management system (not shown in the figure). The battery management system is electrically connected to the battery module formed by the multiple battery cells 20 and is used to detect parameters such as the voltage, temperature, and current of the battery 100 to ensure that the above working parameters of the battery are within a safe range. At the same time, the battery management system can also control the charging and discharging process to prevent overcharging, over-discharging, short-circuiting, etc., and protect the battery 100 from being damaged.
[0063] Figure 3 It is a schematic structural diagram of the electrical connector provided by some embodiments of the present application from a first perspective. Figure 4 It is a schematic structural diagram of the electrical connector provided by some embodiments of the present application from a second perspective.
[0064] Combined with the attachedFigure 3 and the attached Figure 4 As shown in Figure 4 , an embodiment of the present application provides an electrical connector 30, which includes a connector body 31 and a magnetic shielding member 32: the connector body 31 is used to connect a conductive wire harness 40; the magnetic shielding member 32 is connected to the connector body 31 and is provided with a wire passing hole 321 for the conductive wire harness 40 to pass through.
[0065] The connector body 31 of this embodiment is used to connect the conductive wire harness 40 and the vehicle 1000. One end of the two opposite ends of the connector body 31 is provided with a connection plug 311 for connecting to the vehicle 1000, and the other end is provided with a first terminal 312. The cross-sectional shape of the connection plug 311 can be the rectangle shown in the figure, and of course it can also be other shapes such as a circle or a hexagon. The outer wall surface of the connection plug 311 is provided with a plurality of strip-shaped flanges 3111, and the inside of the connection plug 311 is provided with a second terminal 3112 connected to the first terminal 312. On one side or both sides along the first direction X (the first direction X is the direction from the first end 331 to the second end 332 of the following connecting member 33) in the figure, the outer wall surface of the connection plug 311 is provided with a plugging structure 3113 for adapting to the socket (not shown in the figure) of the vehicle 1000.
[0066] The conductive wire harness 40 of this embodiment can be a low-voltage wire harness. A low-voltage wire harness refers to a wire harness that carries a voltage less than a defined voltage (for example, 60V). Therefore, the conductive wire harness 40 is easily affected by the high-voltage electromagnetic field inside the battery 100 described below. A high-voltage wire harness refers to a wire harness that carries a voltage greater than the defined voltage (for example, 60V). The low-voltage wire harness and the high-voltage wire harness can have different defined voltage values according to different design requirements, and this embodiment does not list them in detail.
[0067] The magnetic shielding member 32 of this embodiment can be a magnet, such as materials like neodymium iron boron (NdFeB), alnico, or samarium cobalt (SmCo). The inner wall surface of the magnetic shielding member 32 at the wire passing hole 321 can be in contact with or have a gap with the outer wall surface of the outer skin of the conductive wire harness 40. By using the magnetic shielding member 32 to form a shielding magnetic field, the external electromagnetic field is absorbed and guided, and then the external magnetic field is transferred or weakened to reduce the influence on the conductive wire harness 40, which helps to stabilize the working performance of the conductive wire harness 40 and further improves the working stability of the entire battery 100.
[0068] Figure 5 It is a schematic structural diagram of the magnetic shielding member of the electrical connector provided by some embodiments of the present application;
[0069] Combined with the attached Figure 5As shown, in some examples, optionally, the magnetic shielding member 32 includes a first split body 322 and a second split body 323. The first split body 322 is provided with a first wire groove 3221, and the second split body 323 is provided with a second wire groove 3231. The first wire groove 3221 and the second wire groove 3231 enclose a wire passing hole 321.
[0070] The first split body 322 and the second split body 323 of this embodiment may be structures in an axisymmetric form. For example, both are in an arc shape or approximately U-shaped. Of course, they may also be asymmetric structures with different sizes, as long as they can enclose the above-mentioned wire passing hole 321.
[0071] By designing the magnetic shielding member 32 as the interconnected first split body 322 and second split body 323, during assembly, the first split body 322 can be first connected to the connector body 31, then the wire harness 40 is connected to the connector body 31, and the wire harness 40 is located in the first wire groove 3221. Finally, the first split body 322 and the second split body 323 are butted, so that the wire harness 40 is located in the wire passing hole 321 enclosed by the first wire groove 3221 and the second wire groove 3231, which is beneficial to the connection of the wire harness 40 by the electrical connector 30 and facilitates the assembly operation of the wire harness 40, improving the assembly efficiency.
[0072] In some examples, optionally, the first split body 322 and the second split body 323 are connected in a detachable manner.
[0073] Detachable connection means that the first split body 322 and the second split body 323 can be disconnected after being connected, and its scope can be understood to include detachable connections of mechanical structures and adhesions.
[0074] Taking the first split body 322 and the second split body 323 as arc-shaped members as an example, one end of the opposite ends of the first split body 322 and one end of the opposite ends of the second split body 323 are detachably connected, and the other end of the opposite ends of the first split body 322 and the other end of the opposite ends of the second split body 323 are connected in a detachable manner. There are various detachable connection methods, which are specifically given below.
[0075] By detachably connecting the first split body 322 and the second split body 323, while facilitating assembly, it is also convenient to split the first split body 322 and the second split body 323 for the maintenance of the wire harness 40.
[0076] In some examples, optionally, the first split body 322 and the second split body 323 are connected by plugging, snap connection, adhesion or magnetic attraction connection.
[0077] When the first split body 322 and the second split body 323 are plugged together, a slot (not shown in the figure) can be provided at one end of one of them, and a plug (not shown in the figure) can be provided at one end of the other, and the plug is plugged into the slot.
[0078] When the first split body 322 and the second split body 323 are snap-connected, a second card slot (not shown in the figure) can be provided at one end of one of them, and a second snap (not shown in the figure) can be provided at one end of the other. When the first split body 322 and the second split body 323 are adhesively bonded, an adhesive surface (not shown in the figure) can be provided at the ends of both of them, and they are adhesively bonded with glue. When the two are magnetically connected, the first split body 322 and the second split body 323 can be designed to have opposite magnetic polarities at the connection part, so that the ends of the two attract each other to enclose the wire routing hole 321.
[0079] The connection between the first split body 322 and the second split body 323 is realized by means of plugging, snap connection, adhesive bonding or magnetic attraction, etc. The structure is simple, and it is easy to assemble and disassemble the first split body 322 and the second split body 323, and at the same time, the manufacturing cost is relatively low.
[0080] In some examples, optionally, the magnetic shielding member 32 is annular. The magnetic shielding member 32 has opposite annular inner wall surfaces 324 and annular outer wall surfaces 325 in the radial direction, and the annular inner wall surface 324 encloses the wire routing hole 321.
[0081] By designing the magnetic shielding member 32 to be annular, the annular structure can make the magnetic field of the wire harness 40 better concentrated, reduce the magnetic field loss, and improve the utilization rate of the magnetic field; at the same time, the annular structure can match with the outer protective layer of the wire harness 40, so that the annular inner wall surface 324 of the magnetic shielding member 32 is close to or even wraps the wire harness 40, improving the shielding and protection effect on the wire harness 40.
[0082] Of course, the structural form of the magnetic shielding member 32 in this embodiment is not limited to this. For example, the magnetic shielding member 32 can also be in the shape of a rectangle, a hexagon, a rhombus, etc., and this embodiment will not list them too much.
[0083] Figure 6 It is a schematic structural diagram of a connecting member of an electrical connector provided in some embodiments of the present application.
[0084] Combined with the appended Figure 3 appendix Figure 4 appendix Figure 6As shown, in some examples, optionally, the electrical connector 30 further includes a connecting member 33. The connecting member 33 includes a first end 331 and a second end 332 facing away from each other. The first end 331 is connected to the connector body 31, and the second end 332 is connected to the magnetic shielding member 32. The connecting member 33 is provided with a wire routing channel 333 for the conductive wire bundle 40 to pass through, and the wire routing channel 333 extends from the first end 331 to the second end 332.
[0085] Since the radial dimension of the conductive wire bundle 40 is small, in order to adapt to the conductive wire bundle 40, the dimension of the magnetic shielding member 32 in the second direction Y should not be too large. The dimension of the magnetic shielding member 32 in the second direction Y needs to be designed to be much smaller than that of the connector body 31. The second direction Y intersects with the aforementioned first direction X. For example, the second direction Y is perpendicular to the first direction X.
[0086] Therefore, in this embodiment, a connecting member 33 is also configured. Through the connecting member 33, it is convenient to connect the relatively large connector body 31 and the relatively small magnetic shielding member 32. At the same time, the wire routing channel 333 of the connecting member 33 can also play a certain role in protecting and restricting the conductive wire bundle 40.
[0087] In some examples, optionally, the connecting member 33 is connected to the connector body 31 in a detachable manner.
[0088] That is, the first end 331 of the connecting member 33 is detachably connected to the connector body 31. There are various detachable connection methods, such as plugging, bolt connection, bonding, and the following snap connection.
[0089] By designing the connecting member 33 and the connector body 31 to be detachably connected, it is beneficial for assembly and can also facilitate the disassembly of the connecting member 33 and the connector body 31, so as to repair the conductive wire bundle 40 inside the connecting member 33.
[0090] In some examples, optionally, the connecting member 33 is provided with either a first snap 334 or a first slot 3114, and the connector body 31 is provided with the other of the first snap 334 or the first slot 3114, and the first snap 334 and the first slot 3114 are snap-connected.
[0091] In this embodiment, the connecting member 33 and the connector body 31 are snap-connected. The connecting member 33 and the connector are detachably connected through the first snap 334 and the first slot 3114. The structure is simple and it is easy to assemble and disassemble for maintenance.
[0092] Specifically, the connecting member 33 may be provided with outwardly extending first buckles 334. A plurality of first buckles 334 are arranged at intervals along the circumference of the first end 331 of the connecting member 33. A connecting frame 3115 is provided at one end of the connector body 31 facing the connecting member 33. The connecting frame 3115 is provided with a plurality of first card slots 3114 arranged at intervals along its circumference. The plurality of first card slots 3114 are in one-to-one correspondence and mating connection with the plurality of first buckles 334 to improve the connection stability between the connecting member 33 and the connector body 31.
[0093] In some examples, optionally, from the first end 331 to the second end 332, the size of the connecting member 33 in the first direction X gradually decreases, and the first direction X intersects with the direction from the first end 331 to the second end 332.
[0094] The size of the connecting member 33 in the first direction X gradually decreases from the first end 331 to the second end 332, so that the connecting member 33 forms a structure similar to a conical cylinder, and the size of the second end 332 of the connecting member 33 is smaller. Adaptively, the size of the magnetic shielding member 32 can be reduced, thereby reducing the consumables and the occupied space of the connecting member 33 and the magnetic shielding member 32.
[0095] In some examples, optionally, from the first end 331 to the second end 332, the size of the wire routing channel 333 in the first direction X gradually decreases.
[0096] In this way, the structure of the wire routing channel 333 can be formed to be approximately conical, so that the shape of the wire routing channel 333 conforms to the shape of the internal wire harness 40 inside, and the internal wire harness can be better constrained and protected.
[0097] In some examples, optionally, one end of the connecting member 33 is provided with an opening 3331 communicating with the wire routing channel 333, and the opening 3331 extends from the first end 331 to the second end 332.
[0098] By providing the opening 3331, the wire harness 40 can be conveniently installed in the wire routing channel 333 directly through the opening 3331 and connected to the connector body, improving the assembly efficiency of the electrical connector 30 and the wire harness 40.
[0099] In some examples, optionally, the magnetic shielding member 32 includes a first split body 322 and a second split body 323. The first split body 322 is provided with a first wire slot 3221, and the second split body 323 is provided with a second wire slot 3231. The first wire slot 3221 and the second wire slot 3231 enclose a wire hole 321. The connecting member 33 is connected to the first split body 322, and the wire routing channel 333 is communicated with the first wire slot 3221.
[0100] By connecting the wiring channel 333 with the first wire slot 3221, the conductive wire harness 40 can be directly installed in the connector 33 and the first wire slot 3221 through the opening 3331 and the first wire slot 3221. Then, by connecting the second sub - body 323 to the first sub - body 322, the binding and electromagnetic shielding of the conductive wire harness 40 are achieved, facilitating the installation of the conductive wire harness 40 and improving the assembly efficiency of the conductive wire harness 40.
