Description

Technical Field

[0001] The present application relates to the field of electronic devices, and in particular to a high-voltage connector, a battery device and an electrical device. Background Art

[0002] High-voltage connectors are electrical connection devices that can be used in different electrical equipment or systems to achieve effective transmission of power and signals. In new energy vehicles, high-voltage connectors are indispensable key components that must have a high degree of safety and reliability to improve the safety performance of the vehicle. Utility Model Content

[0003] In view of this, the embodiments of the present application provide a high-voltage connector, a battery device, and an electrical device, which can improve the safety of the high-voltage connector, and further improve the safety of the battery device and the electrical device.

[0004] An embodiment of the first aspect of the present application provides a high-voltage connector, comprising: a shell, comprising a main body and a flange portion arranged along a first direction; at least one terminal group, one terminal group comprising two terminals, at least in some terminal groups, the terminals are inserted into the shell along the first direction and protrude from the flange portion, and the two terminals are spaced apart along a second direction perpendicular to the first direction; an insulating member, arranged in the flange portion and located between the two terminals, the insulating member comprising two guide bevels distributed along the second direction, the two guide bevels respectively facing the two terminals and capable of guiding the two terminals to move in different directions.

[0005] The high-voltage connector provided in the above embodiment can achieve physical isolation of the two terminals by arranging an insulating member between the two terminals. Furthermore, by arranging two guiding slopes on the sides of the insulating member facing the two terminals, the two terminals can be guided to move in different directions when the terminals are deformed or loosened. Therefore, the above design can effectively reduce the risk of accidental short circuit between the two terminals, thereby improving the safety and reliability of the high-voltage connector.

[0006] In some embodiments, the two guiding inclined surfaces are parallel to the first direction and are inclined toward the same side relative to a third direction, and the third direction is perpendicular to the first direction and the second direction.

[0007] In the above design, the insulating member can guide the two wiring terminals to move in a direction away from each other, which can better separate the two wiring terminals and further reduce the risk of accidental short circuit between the two wiring terminals.

[0008] In some implementations, the two guiding ramps are arranged in parallel.

[0009] In the above design, the two guide slopes can guide the two terminal blocks to move in opposite directions. The guiding path of the guide slopes is more reasonable, and the thickness of the insulating part is consistent at all locations, so the strength of the insulating part is also consistent. This can avoid the appearance of weak parts on the insulating part and reduce the risk of deformation and damage of the insulating part.

[0010] In some embodiments, the guiding slope is a planar structure.

[0011] In the above design, the guiding slope has a simple structure and can guide the terminal to slide in the designed direction. At the same time, the guiding slope is subjected to relatively balanced force and is not easily deformed or damaged.

[0012] In some implementations, an inclination angle is formed between the guiding slope and the second direction, and the magnitude of the inclination angle is 15°-75°.

[0013] In the above design, the inclination angle of the guiding slope is reasonable, the guiding slope can provide sufficient inclination to smoothly guide the movement of the terminal, and the insulating part occupies less space in the second direction, which is conducive to improving the structural compactness of the high-voltage connector.

[0014] In some implementations, the guiding slope has a head end and a tail end, the guiding slope can guide the terminal to move from the head end to the tail end, and the head end has a stopper, and the stopper is used to abut against the terminal.

[0015] In the above design, the stopper can block the connection terminal from sliding toward the head end and can prevent the connection terminal from slipping off the head end of the guide slope, thereby ensuring that the connection terminal can better move along the guide path provided by the guide slope.

[0016] In some embodiments, one side of the connection terminal along the second direction is embedded in a space enclosed by the stop portion and the guiding inclined surface.

[0017] In the above design, the wiring terminal and the insulating member are assembled compactly, and a large sliding space is reserved on the guide slope.

[0018] In some implementations, the connection terminal is a copper bus terminal, and a side of the copper bus terminal facing the insulating member has a chamfer.

[0019] In the above design, by designing a chamfered structure, an avoidance portion can be formed on the wiring terminal, so that the wiring terminal can be compactly matched with the insulating member.

[0020] In some embodiments, the chamfer forms an inclined surface, and the inclined surface has the same inclination angle as the relative guiding inclined surface; or, the chamfer is in an arc structure.

[0021] In the above design, by further improving the specific structure of the chamfer, the matching effect between the wiring terminal and the guiding inclined surface can be improved.

[0022] In some implementations, the guiding slope is spaced apart from the connecting terminal.

[0023] In the above design, the spacing setting is conducive to air circulation, thereby improving the heat dissipation effect of the terminal block.

[0024] In some embodiments, the high-voltage connector also includes an insulating sleeve and a mounting platform, the insulating sleeve is sleeved on the portion of the terminal extending out of the flange portion, and the end of the terminal extends out of the insulating sleeve, the mounting platform is arranged on the flange portion and located between the two insulating sleeves, and the insulating member is arranged on the mounting platform.

[0025] In the above design, the insulating sleeve can provide reliable physical protection for the terminal block and protect the local position of the terminal block from external mechanical damage. The insulating sleeve can also improve the overall strength and pressure resistance of the terminal block and reduce the risk of deformation and damage of the terminal block. In addition, the mounting table can support the insulating part to ensure that the insulating part can be aligned with the deformed part of the terminal block.

[0026] In some embodiments, an end of the insulating sleeve away from the flange portion abuts against the insulating member.

[0027] In the above design, the insulating sleeve can provide support for the insulating member in the first direction.

[0028] In some implementations, the insulating member and the mounting platform are integrally formed; or, the insulating member, the mounting platform, and the housing are integrally formed.

[0029] In the above design, the integrated structure can reduce stress concentration at the connection positions between the insulating member and the mounting platform, and between the mounting platform and the shell, and improve the overall mechanical strength of the insulating member, the mounting platform and the shell, thereby helping to improve the long-term reliability of the high-voltage connector.

[0030] An embodiment of a second aspect of the present application provides a battery device, comprising a battery cell and the high-voltage connector of the first aspect, wherein the high-voltage connector is electrically connected to the battery cell.

[0031] The battery device provided in the above embodiment, by adopting the battery device in the first aspect, improves the reliability and safety of the battery device.

[0032] An embodiment of the third aspect of the present application provides an electrical device, comprising the battery device of the second aspect, wherein the battery device is used to store or provide electrical energy.

[0054] The battery device of a new energy vehicle is usually equipped with several high-voltage connectors, which can be used to connect the battery cells in the battery device and connect the battery device to other electrical systems of the vehicle, thereby assisting the normal operation of the vehicle. High-voltage connectors involve high voltage and high current, and their safety performance is particularly important. If an electrical fault occurs during use, it may cause damage to key components such as the battery device, battery management system, and other electrical systems of the vehicle, and in severe cases may cause fire or explosion.

[0055] Existing high-voltage connectors already have high safety performance, but in some extreme situations, such as a serious collision during vehicle driving or impact testing before the vehicle leaves the factory, the high-voltage connector is at risk of short circuiting due to severe structural deformation. Therefore, it is necessary to further improve the structure of the high-voltage connector to enhance its safety performance.

[0056] Based on the above problems, an embodiment of the present application provides a high-voltage connector, including a housing, a terminal and an insulating member, wherein the terminal is inserted into the housing, and one end of the terminal protrudes from the flange portion of the housing, the insulating member is arranged on the flange portion and is located between the two terminals, and the insulating member includes two guiding bevels, the two guiding bevels are respectively facing the two terminals, and are used to guide the two terminals to move in different directions. When the high-voltage connector is hit by a severe external force and the terminal is deformed or loosened, the insulating member can guide the terminal to deform in the designed direction to reduce the risk of the two terminals accidentally touching and short-circuiting, thereby effectively improving the safety and reliability of the high-voltage connector by designing the insulating member and improving the structure of the insulating member.

[0061] Please refer to Figure 2 , Figure 2 The exploded view of the battery device 100 provided in some embodiments of the present application.

The battery cell 20 and the high-voltage connector 30 are accommodated in the box body 10, and the battery cell 20 is electrically connected to the high-voltage connector 30. It should be noted that Figure 2The drawings shown are only used to illustrate a specific setting position of the high-voltage connector 30, and are not used to define the specific structure of the high-voltage connector 30. The box 10 is used to provide a storage space for the battery cell 20 and the high-voltage connector 30, and the box 10 can adopt a variety of structures.

[0065] The technical solution provided in the embodiments of the present application is described below with reference to the accompanying drawings.

[0066] According to some embodiments of the present application, referring to Figures 3 to 5 , Figure 3 This is a schematic diagram of the structure of the high voltage connector 30 provided in an embodiment of the present application. Figure 4 A top view of a high voltage connector 30 provided in an embodiment of the present application. Figure 5 A front view of a high-voltage connector provided in an embodiment of the present application. An embodiment of the first aspect of the present application provides a high-voltage connector 30. The high-voltage connector 30 includes a housing 31, at least one terminal group and an insulating member 33. The housing 31 includes a main body 311 and a flange portion 312 arranged along a first direction X. The terminal group includes two terminals 32, and in at least some of the terminal groups, the terminal 32 is inserted into the housing 31 along the first direction X, and one end protrudes from the flange portion 312, and the two terminals 32 are spaced apart along a second direction Y perpendicular to the first direction X. The insulating member 33 is disposed on the flange portion 312 and is located between the two terminals 32, and the insulating member 33 includes two guide bevels 331 distributed along the second direction Y, and the two guide bevels 331 are respectively facing the two terminals 32 and can guide the two terminals 32 to move in different directions.

[0067] like Figure 3 As shown, the length direction of the shell 31 is defined as the first direction X, the width direction of the shell 31 is defined as the second direction Y, and the height direction of the shell 31 is defined as the third direction Z. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0068] The shell 31 is used to provide an assembly basis and necessary mechanical support for the components of the high-voltage connector 30, and its internal structure, shape and size are designed according to the assembly requirements of the terminal block 32. The main body 311 is the basic part of the shell 31, and its structure can be various, for example, it can be cylindrical, rectangular, etc. One or more channels for accommodating the terminal block 32 can be set inside the main body 311. The flange part 312 is arranged at one end of the main body 311 along the first direction X, and the outer contour of the flange part 312 on the plane perpendicular to the first direction X can be square, circular or other geometric shapes. A socket connected to the channel of the main body 311 can be provided on the flange part 312, and the terminal block 32 is assembled on the flange part 312 and the main body 311 through the socket. The flange portion 312 has a certain thickness along the first direction X, and has an installation plane on the side away from the main body 311. The installation plane can provide an installation space to assemble components such as the insulating member 33. The flange portion 312 can also be provided with a mounting hole 3121, and the mounting hole 3121 is used to assemble fasteners such as bolts and screws to achieve the connection and fixation of the high-voltage connector 30 with an external device, wherein the external device may be, but is not limited to, a distribution box, a box 10 of a battery device 100, and the like. The main body 311 and the flange portion 312 can be provided as a whole, or combined in a ball by welding, bolt connection, etc. The material of the main body 311 and the flange portion 312 can be a variety of materials, for example, engineering plastics, metals or other high-strength composite materials. The material of the main body 311 and the flange portion 312 can be the same or different. It can be understood that when the main body 311 and the flange portion 312 are metal parts, insulation protection is required to prevent short circuits.

[0069] The terminal block 32 is a conductive structure of the high-voltage connector 30. The terminal block 32 includes a male end protruding from the flange portion 312 and a female end inserted into the main body portion 311. The two connecting ends of the terminal block 32 can be connected to different cables or wires, etc., so as to form an electrical path between different electrical devices. The shape of the terminal block 32 can be various, for example, it can be cylindrical, sheet-shaped, etc., and according to its structure, it can be electrically connected to the cable or wire by crimping, welding, screw connection, etc. The terminal block 32 is made of a material with good electrical conductivity and high mechanical strength, such as copper, copper alloy, etc. It can be understood that the high-voltage connector 30 can include one or more terminal blocks, and the terminal blocks can have different arrangements. The two terminal blocks 32 in each terminal block group have different polarities, and the terminal blocks 32 need to be arranged at intervals to ensure electrical isolation between the terminal blocks 32.

[0070] The insulating member 33 has electrical insulation performance. The insulating member 33 has a certain thickness in the second direction Y and forms two smooth guide slopes 331. The shape, size and inclination direction of the two guide slopes 331 can be designed according to the structure and application requirements of the terminal block 32, and the inclination direction and inclination angle of the two guide slopes 331 can be the same or different. The insulating member 33 and the flange portion 312 can be integrally arranged, or combined together by welding, bonding, etc. The insulating member 33 can be made of a variety of materials, such as ceramics, rubber, plastic, etc.

[0071] It should be noted that, in the aforementioned “two guide slopes 331 capable of guiding the two connecting terminals 32 to move in different directions”, the movement of the connecting terminals 32 may be caused by deformation of the connecting terminals 32, or may be caused by loosening or falling off of the connecting terminals 32. In a normal state, the insulating part 33 and the two connecting terminals 32 are independent of each other, and there is no movement tendency of the connecting terminals 32 relative to the insulating part 33, and there is no guiding and guided relationship between the insulating part 33 and the connecting terminals 32.

[0072] The following is a description of the function of the insulating member 33 in conjunction with a specific embodiment. Figure 5 The high-voltage connector 30 includes two terminals 32, namely, a first terminal 32a and a second terminal 32b. The insulating member 33 includes two guiding slopes 331, namely, a first guiding slope 331a and a second guiding slope 331b. The first guiding slope 331a faces the first terminal 32a, and the second guiding slope 331b faces the second terminal 32b. The insulating member 33 includes a first end 333 and a second end 334. After the high-voltage connector 30 is severely impacted, the first terminal 32a and / or the second terminal 32b are deformed and bent toward the insulating member 33. After the first terminal 32a contacts the first guiding slope 331a, as shown in FIG. Figure 5 As shown by the middle arrow M, the first guide slope 331a can guide the first terminal 32a to deform toward the first end 333. After the second terminal 32b contacts the second guide slope 331b, as shown in FIG. Figure 5 As shown by the middle arrow N, the second guide slope 331b can guide the second terminal 32b to deform toward the second end 334, so that the first terminal 32a and the second terminal 32b move away from each other during the movement and will not squeeze the insulating member 33 at the same position and cause the insulating member 33 to break, thereby avoiding the problem of accidental short circuit between the two terminals 32.

[0073] It is understandable that after the high-voltage connector 30 is subjected to a severe external impact, both terminals 32 may be deformed or loosened at the same time, or only one of the terminals 32 may be deformed or loosened, which is specifically related to the force applied to the terminals 32. At the same time, the movement of the terminals 32 does not necessarily lead to the failure of the high-voltage connector 30. When the terminals 32 are slightly deformed, they may still maintain good conductive properties.

[0074] The high-voltage connector 30 provided in the embodiment of the present application can achieve physical isolation of the two wiring terminals 32 by setting an insulating member 33 between the two wiring terminals 32. Furthermore, by setting two guide bevels 331 on the sides of the insulating member 33 facing the two wiring terminals 32, and tilting the two guide bevels 331 toward the same side, the insulating member 33 can guide the two wiring terminals 32 to move in different directions when the wiring terminals 32 are deformed or loosened. Therefore, the above design can effectively reduce the risk of accidental short circuit between the two wiring terminals 32, thereby improving the safety and reliability of the high-voltage connector 30.

[0075] In addition, in some situations, such as when the high-voltage connector 30 is subjected to vibration or installation errors occur during the installation process, the external force impact on the high-voltage connector 30 is relatively small, and the insulating member 33 can provide mechanical support for the terminal 32, thereby maintaining the position of the terminal 32 stable and reducing the deformation of the terminal 32, thereby reducing the risk of damage to the high-voltage connector 30.

[0076] See also Figure 3 and Figure 5 In some embodiments, the two guiding inclined surfaces 331 of the insulating member 33 are parallel to the first direction X and are inclined toward the same side relative to the third direction Z.

[0077] The inclined setting of the guiding inclined surface 331 relative to the third direction Z can be understood as: the normal line of the guiding inclined surface 331 is not perpendicular and parallel to the third direction Z. The inclined setting of the two guiding inclined surfaces 331 toward the same side relative to the third direction Z can be understood as: in the XYZ coordinate system, the two guiding inclined surfaces 331 are deflected toward the same side compared to the XOZ plane.

[0078] With the above design, the insulating member 33 can guide the two connecting terminals 32 to move away from each other, which can better separate the two connecting terminals 32, thereby further reducing the risk of the two connecting terminals 32 accidentally touching and short-circuiting.

[0079] It can be understood that in some embodiments, the two guide slopes 331 of the insulating member 33 can be tilted toward different sides relative to the third direction Z. By adjusting the inclination angle formed between the guide slopes 331 and the third direction Z, the two guide slopes 331 maintain different degrees of inclination, thereby achieving the effect of guiding the two terminal blocks 32 to move in different directions.

[0080] See also Figure 3 and Figure 5 In some embodiments, the two guiding inclined surfaces 331 of the insulating member 33 are arranged in parallel.

[0081] In the third direction Z, the thickness of the insulating member 33 is uniform at all locations, and the angles between the two guiding inclined surfaces 331 and the third direction Z are equal.

[0082] With the above design, on the one hand, the insulating member 33 can guide the two connecting terminals 32 to move in opposite directions, and the guiding path of the guiding slope 331 is more reasonable. On the other hand, the insulating member 33 has a simple structure, and the assembly position and setting angle are more flexible. In addition, since the thickness of the insulating member 33 is consistent at various locations, the strength of the insulating member 33 is also consistent at various locations, which can avoid the occurrence of weak parts and help reduce the risk of deformation and damage of the insulating member 33.

[0083] It can be understood that, in some cases, the thickness of the insulating member 33 may be varied, and the two guiding inclined surfaces 331 may have the same inclination trend but different inclination angles.

[0084] In some embodiments, the guiding slope 331 is a planar structure.

[0085] The guiding slope 331 is a two-dimensional plane, and its surface has no curvature or bending.

[0086] With the above design, the guiding slope 331 has a simple structure and can effectively guide the connecting terminal 32 to slide in the designed direction. At the same time, the guiding slope 331 is subjected to relatively balanced force and is not easily deformed or damaged.

[0087] It can be understood that in some embodiments, the guiding inclined surface 331 can also be designed as a smooth arc surface structure, which can be specifically designed according to actual conditions.

[0088] In some embodiments, an inclination angle is formed between the guiding inclined surface 331 and the second direction Y, and the magnitude of the inclination angle is 15°-75°.

[0089] For example, the tilt angle may be 15°, 30°, 45°, 60°, or 75°.

[0090] The normal of the guiding inclined surface 331 forms an angle with the second direction Y, and the angle is complementary to the above-mentioned inclination angle. The inclination angles of the two guiding inclined surfaces 331 can be equal or unequal. The equal inclination angles of the two guiding inclined surfaces 331 means that the two guiding inclined surfaces 331 are arranged in parallel.

[0091] The inclination of the guiding slope 331 directly affects the guiding effect of the connecting terminal 32, and also affects the arrangement of components on the flange portion 312. With the above design, on the one hand, the guiding slope 331 can provide a sufficient inclination to smoothly guide the movement of the connecting terminal 32, and on the other hand, the insulating member 33 occupies a relatively small space in the second direction Y, thereby achieving effective guidance of the connecting terminal 32 in a limited space, thereby facilitating the improvement of the structural compactness of the high-voltage connector 30.

[0092] Please refer to Figure 3 and Figure 5 In some embodiments, the guide slope 331 has a head end 3311 and a tail end 3312 , and the guide slope 331 can guide the terminal 32 to move from the head end 3311 to the tail end 3312 . The head end 3311 has a stopper 332 , and the stopper 332 is used to resist the terminal 32 .

[0093] For example Figure 5 Arrows M and N indicate the guiding directions of the two guiding slopes 331 , respectively. The guiding directions of the guiding slopes 331 are parallel to the guiding slopes 331 and perpendicular to the first direction X. In the guiding directions of the guiding slopes 331 , the guiding slopes 331 include a head end 3311 and a tail end 3312 .

[0094] The stopper 332 protrudes from the surface of the guiding inclined surface 331 , is close to one end of the guiding inclined surface 331 , and is extended along the first direction X. Since the guiding directions of the two guiding inclined surfaces 331 are different, the first ends 3311 of the two guiding inclined surfaces 331 are respectively located at opposite ends of the insulating member 33 . Figure 5 The insulating member 33 includes a first guiding inclined surface 331a and a second guiding inclined surface 331b. A first stopper 332a is arranged on the first guiding inclined surface 331a, and a second stopper 332b is arranged on the second guiding inclined surface 331b. The first stopper 332a and the second stopper 332b are staggered.

[0095] In actual situations, the connection terminal 32 may be impacted by external forces from various directions, and external forces impacted from different directions may cause the connection terminal 32 to have a tendency to move in different directions. In the above embodiment, a stopper 332 is provided at the head end 3311 of the guide slope 331, which can prevent the two connection terminals 32 from sliding toward the same end of the insulating member 33, and at the same time prevent the connection terminal 32 from slipping off the head end 3311 of the guide slope 331, so that this design can enable the connection terminal 32 to better move in the designed direction according to the guide path provided by the guide slope 331.

[0096] It can be understood that in some embodiments, in order to further improve the reliability of the insulating member 33 , a stopper 332 may be provided at the head end 3311 and the tail end 3312 of each guiding inclined surface 331 .

[0097] In some embodiments, one side of the connection terminal 32 along the second direction Y is embedded in a space enclosed by the stopper 332 and the guide slope 331 .

[0098] Since the guiding inclined surface 331 is arranged at an angle, and the stopper 332 protrudes from the surface of the guiding inclined surface 331 , an open angle space can be formed between the stopper 332 and the guiding inclined surface 331 at the position where the stopper 332 is arranged.

[0099] In the above embodiment, one side of the connecting terminal 32 is embedded in the space enclosed by the stop portion 332 and the guide slope 331, which can improve the compactness of the assembly between the connecting terminal 32 and the insulating member 33. At the same time, the connecting terminal 32 is close to the stop portion 332, and a larger sliding space can be reserved on the guide slope 331.

[0100] See also Figure 3 and Figure 5 In some embodiments, the connection terminal 32 is a copper bar terminal, and the copper bar terminal has a chamfer on one side facing the insulating member 33 .

[0101] The copper bar terminal includes a flat copper sheet, which has a certain thickness in the third direction Z and two side surfaces in the second direction Y. The side surface of the copper bar terminal facing the insulating member 33 is cut to form a chamfered structure. The size of the chamfer depends on the design requirements. In some embodiments, the first end 3311 of the guide slope 331 is designed with a stopper 332, and the chamfer on the terminal 32 is close to the stopper 332.

[0102] The copper busbar terminal can be connected to the cable, wire or other electrical equipment by bolt connection, welding or crimping.

[0103] In the above embodiment, by designing a chamfered structure on the connecting terminal 32 , the connecting terminal 32 has an inclined edge, so that the connecting terminal 32 can better adapt to the structure of the guiding slope 331 , and the connecting terminal 32 and the guiding slope 331 can fit compactly.

[0104] In some embodiments, the chamfer forms an inclined surface 321 , and the inclined surface 321 and the opposite guiding inclined surface 331 have the same inclination angle.

[0105] After the connecting terminal 32 is chamfered, an inclined edge can be formed, and an inclined surface 321 facing the insulating member 33 can be formed. It can be understood that the size of the chamfer determines the size of the inclined surface 321, and directly affects the contact area between the inclined surface 321 and the guiding inclined surface 331. Specifically, the larger the chamfer, the larger the size of the inclined surface 321, and thus the larger the contact area between the inclined surface 321 and the guiding inclined surface 331.

[0106] With the above design, on the one hand, the inclination direction and inclination angle of the inclined surface 321 are consistent with the inclination direction and inclination angle of the corresponding guiding inclined surface 331, so that after the terminal 32 is squeezed by external force, the inclined surface 321 can fit onto the guiding inclined surface 331, the terminal 32 is in good contact with the guiding inclined surface 331, and the wear of the terminal 32 during the sliding process along the guiding inclined surface 331 is also small. On the other hand, the chamfer changes the force direction of the terminal 32 when it is squeezed, so that the terminal 32 can better move along the guiding path provided by the guiding inclined surface 331.

[0107] In some embodiments, a chamfer is provided on the connection terminal 32, and the chamfer is in an arc structure.

[0108] In some cases, the guide slope 331 is an arc structure. Designing the chamfer as an arc structure can improve the adaptability of the terminal 32 and the guide slope 331. At the same time, the arc chamfer can better conform to the shape change of the guide slope 331, which is beneficial to improving the sliding contact effect between the terminal 32 and the guide slope 331.

[0109] It is understandable that in some other embodiments, the wiring terminal 32 may also be a columnar structure, and a connection interface is provided on the wiring terminal 32 to insert a cable or a wire, etc.

[0110] In some embodiments, the guiding inclined surface 331 is spaced apart from the connecting terminal 32 .

[0111] See also Figure 3 and Figure 5In a normal state, along the second direction Y, there is a gap between the guiding slope 331 of the insulating member 33 and the connecting terminal 32 . In an abnormal state, when the connecting terminal 32 is impacted by an external force, the connecting terminal 32 is deformed toward the insulating member 33 and contacts the guiding slope 331 .

[0112] On the one hand, current passes through the terminal block 32 , which may cause heating after long-term use. The spacing setting helps air circulation, thereby improving the heat dissipation effect of the terminal block 32 . On the other hand, the spacing setting provides more operating space, which is conducive to reducing the difficulty of assembling the terminal block 32 and the housing 31 , and reducing the wear between the terminal block 32 and the insulating member 33 .

[0113] See also Figure 3 and Figure 4 In some embodiments, the high-voltage connector 30 further includes an insulating sleeve 34 and a mounting platform 35, the insulating sleeve 34 is sleeved on the portion of the two wiring terminals 32 extending out of the flange portion 312, and the end of the wiring terminal 32 extends out of the insulating sleeve 34, the mounting platform 35 is disposed on the flange portion 312 and is located between the two insulating sleeves 34, and the insulating member 33 is disposed on the mounting platform 35.

[0114] The insulating sleeve 34 may be cylindrical, and the interior of the insulating sleeve 34 may be a hollow structure or a slot may be provided to accommodate the terminal 32. The insulating sleeve 34 may be fixedly connected to the housing 31 by plugging, bonding, threaded connection, etc. The length, thickness, and diameter of the insulating sleeve 34 are determined according to the structure of the terminal 32. It can be understood that the length of the insulating sleeve 34 in the first direction X is less than the length of the terminal 32 protruding from the flange portion 312 to ensure that the end of the terminal 32 can extend out of the insulating sleeve 34, so that the terminal 32 can be normally connected to structures such as cables or wires. The insulating sleeve 34 may be made of a variety of materials, such as polyamide, polytetrafluoroethylene, etc. The number of insulating sleeves 34 matches the number of terminals 32.

[0115] The mounting platform 35 may be block-shaped. On a plane perpendicular to the first direction X, the shape and size of the mounting platform 35 may be designed according to the structure of the insulating sleeve 34 and the insulating member 33. For example, the shape of the mounting platform 35 may be circular, square or other geometric shapes. In the first direction X, the thickness of the mounting platform 35 is consistent with the length of the flange portion 312 protruding from the insulating sleeve 34. It can be understood that the mounting platform 35 needs to be arranged corresponding to the insulating sleeve 34 to ensure that the insulating member 33 can align with the portion of the terminal 32 protruding from the insulating sleeve 34. The mounting platform 35 may be made of a variety of materials, such as ceramic, rubber, plastic, etc.

[0116] On the one hand, the insulating sleeve 34 provides reliable physical protection for the terminal block 32, and can protect the portion of the terminal block 32 that extends out of the housing 31 and is not connected to the cable or wire from external mechanical damage, and provide electrical isolation to reduce the risk of electric shock to the operator. At the same time, the insulating sleeve 34 provides mechanical support for the terminal block 32, and can improve the overall strength and pressure resistance of the terminal block 32, thereby helping to reduce the risk of deformation and damage of the terminal block 32. At the same time, the insulating sleeve 34 can also isolate the terminal block 32 from other components of the high-voltage connector 30, and further improve the electrical isolation effect of the terminal block 32.

[0117] Secondly, the mounting platform 35 can provide an installation space for the insulating member 33 so that the insulating member 33 can be assembled at the designed position. At the same time, since the mounting platform 35 occupies a small space, the installation of the mounting platform 35 is also conducive to improving the rationality of the layout of the components on the flange portion 312.

[0118] In some embodiments, the mounting platform 35 is in a rectangular shape, and includes two side walls distributed along the second direction Y, the two side walls are respectively fitted with two insulating sleeves 34, and the insulating member 33 is arranged on the wall surface of the mounting platform 35 away from the flange portion 312. The mounting platform 35 can provide mechanical support for the insulating sleeve 34, thereby further reducing the risk of deformation, damage and short circuit of the terminal block 32.

[0119] In some embodiments, one end of the insulating sleeve 34 away from the flange portion 312 abuts against the insulating member 33 .

[0120] In some cases, the insulating member 33 is arranged at an angle, and the size of the mounting platform 35 along the second direction Y is relatively small, so that the insulating member 33 at least partially protrudes from the mounting platform 35. The above design can improve the compactness of the assembly between the terminal 32, the insulating member 33 and the insulating sleeve 34. At the same time, the insulating sleeve 34 can provide support for the insulating member 33 in the first direction X, thereby reducing the risk of damage and deformation of the insulating member 33.

[0121] In some embodiments, the insulating member 33 and the mounting platform 35 are integrally formed, or the insulating member 33, the mounting platform 35, and the housing 31 are integrally formed.

[0122] For example, the insulating member 33 , the mounting platform 35 and the housing 31 are all made of nylon, such as PA6 or PA66. The insulating member 33 , the mounting platform 35 and the housing 31 can be integrally formed by an injection molding process.

[0123] The integrated structural design can reduce stress concentration at the connection positions between the insulating member 33 and the mounting platform 35, and between the mounting platform 35 and the shell 31, thereby improving the overall mechanical strength of the insulating member 33, the mounting platform 35 and the shell 31, thereby helping to improve the long-term reliability of the high-voltage connector 30.

[0124] It can be understood that in some other embodiments, the insulating member 33, the mounting platform 35 and the housing 31 can also be connected together by gluing or other methods.

[0125] In some embodiments, a sealing structure is further provided on the flange portion 312 to improve the protection level of the high voltage connector 30. For example, a sealing gasket may be provided at the connection between the terminal 32 and the housing 31 to prevent moisture, dust, etc. from entering the interior of the housing 31. For example, see Figure 3 A sealing groove may be provided on the surface of the flange portion 312 , and a sealing ring 36 may be provided in the sealing groove to improve the sealing effect between the high-voltage connector 30 and external equipment, such as the wall surface of the box body 10 .

[0126] It should be noted that, although the high-voltage connector 30 involved in the embodiment of the present application is developed and designed based on the problems arising from the application of the high-voltage connector 30 in the battery device 100 of a new energy vehicle, the high-voltage connector 30 can be used not only in the battery device 100 of a new energy vehicle, but also in any electrical equipment or electrical equipment or energy storage device that requires the use of the high-voltage connector 30.

[0127] In a specific embodiment provided by the present application, the high-voltage connector 30 includes a housing 31, a terminal 32, an insulating sleeve 34, a mounting platform 35 and an insulating member 33. The high-voltage connector 30 includes a main body 311 and a flange 312 arranged along a first direction X. The terminal 32 is inserted into the housing 31 along the first direction X, and two adjacent terminals 32 are arranged at intervals along the second direction Y, wherein the terminal 32 is partially accommodated in the main body 311 and partially extends out of the flange 312. The insulating sleeve 34 is sleeved on the portion of the terminal 32 extending out of the flange 312, and the end of the terminal 32 extends out of the insulating sleeve 34. The mounting platform 35 is arranged on the flange 312 and is located between the two insulating sleeves 34, and the insulating member 33 is arranged on the mounting platform 35 and is located between the ends of the two terminals 32. The housing 31, the mounting platform 35 and the insulating member 33 are integrally formed by an injection molding process. The insulating member 33 includes two guiding slopes 331 with the same inclination angle. The two guiding slopes 331 face two connecting terminals 32 respectively. The connecting terminals 32 are copper bus terminals. The side of the connecting terminals 32 facing the insulating member 33 has an inclined surface 321 that is in sliding contact with the guiding slopes 331. The insulating member 33 can guide the two connecting terminals 32 to move in different directions. The high-voltage connector 30 provided in the above embodiment has the following advantages: 1. By providing an insulating member 33 and designing a guide bevel 331 structure on the insulating member 33, the two terminals 32 can be guided to move in different directions when the terminal 32 is deformed or loose, thereby reducing the risk of the terminal 32 accidentally touching and short-circuiting; 2. By arranging an insulating sleeve 34 on the terminal 32, the overall strength and pressure resistance of the terminal 32 can be improved, thereby reducing the risk of deformation and damage of the terminal 32. At the same time, the insulating sleeve 34 provides physical protection for the terminal 32, which can protect the terminal 32 from external mechanical damage; 3. By designing a chamfered structure on the terminal 32, the contact effect between the terminal 32 and the guide bevel 331 can be improved, thereby ensuring that the guide bevel 331 can more accurately guide the movement of the terminal 32.

[0128] An embodiment of the second aspect of the present application provides a battery device 100 , including a battery cell 20 and the high-voltage connector 30 in the first aspect, wherein the high-voltage connector 30 is electrically connected to the battery cell 20 .

[0129] For example, the high-voltage connector 30 can be electrically connected to the battery cell 20 through a busbar component, a wire, and other structures, wherein the busbar component is a conductive member that can be used to connect multiple battery cells 20 and collect the currents of multiple current cells. The high-voltage connector 30 can not only be used to realize the series and parallel connection between multiple battery cells 20, but also can be used to connect the battery device 100 with an external electrical system.

[0130] The battery device 100 provided in the embodiment of the present application improves the reliability and safety of the battery device 100 by adopting the high-voltage connector 30 in the first aspect.
