Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to a flexible cable tie, an electrical connection structure, and a battery. Background Technology

[0002] Energy conservation and emission reduction are key to the sustainable development of the automotive industry, and electric vehicles, due to their energy-saving and environmentally friendly advantages, have become an important component of this sustainable development. For electric vehicles, battery technology is a crucial factor in their development.

[0003] There are many connectors inside and outside the battery, and the way these connectors are connected plays a very important role in the reliability of the connection. Summary of the Invention

[0004] This application provides a flexible cable tie, an electrical connection structure, and a battery, which can effectively improve the connection stability and reliability of the cable tie itself.

[0005] In a first aspect, this application provides a flexible cable tie, comprising:

[0006] Tie body;

[0007] The first clamping part and the second clamping part are disposed at the first end of the cable tie body. There is a preset distance between the first clamping part and the second clamping part. The cable tie body has an unfolded state and a wrapped state. In the unfolded state, the first clamping part and the second clamping part are disposed on the same side of the cable tie body. In the wrapped state, the second end of the cable tie body is connected to the first clamping part and the second clamping part.

[0008] In the above embodiments, the flexible cable tie includes two clamping parts, namely a first clamping part and a second clamping part. These two clamping parts can be connected to the cable tie body after the cable tie body is wound up, thereby achieving double fixation of the cable tie body, effectively improving the connection stability and reliability of the flexible cable tie itself, and preventing the flexible cable tie from accidentally coming loose.

[0009] There is a preset distance between the first clamping part and the second clamping part, so that the component to be connected can be set between the first clamping part and the second clamping part, and the component to be connected can also be set between the second clamping part and the second end of the cable tie body, so that the flexible cable tie can wrap at least two components to be connected at the same time; moreover, the component to be connected set between the first clamping part and the second clamping part and the component to be connected set between the second clamping part and the second end of the cable tie body can be separated by the second clamping part, for example, so that electrical isolation or thermal isolation can be achieved between the two components to be connected, thereby meeting the isolation requirements between the components to be connected.

[0010] When the cable tie body is in the unfolded state, the first clamping part and the second clamping part are located on the same side of the cable tie body. This allows at least two components to be connected to be placed on the same side of the cable tie body. Then, by winding the cable tie body, the components connected by the flexible cable tie are wrapped within the wrapping space of the cable tie body, thus achieving the protection of the components to be connected.

[0011] In some embodiments, the cable tie body is provided with a plurality of first locking teeth arranged along its length direction, a first locking part is provided with a first locking hole, a second locking part is provided with a second locking hole, and the plurality of first locking teeth are engaged with the first locking part through the first locking hole and engaged with the second locking part through the second locking hole.

[0012] In the above embodiments, the cable tie body and the first clamping part are connected by the engagement of the first clamping tooth and the first clamping hole, and the cable tie body and the second clamping part are connected by the engagement of the first clamping tooth and the second clamping hole. This can improve the convenience of connection and facilitate rapid connection.

[0013] When the flexible cable tie needs to be tightened, the second end of the cable tie body passes sequentially through the first locking hole on the first locking part and the second locking hole on the second locking part. One or more of the multiple first locking teeth engage with the first locking hole, and another or more of the multiple first locking teeth engage with the second locking hole. By setting multiple first locking teeth, the locking position can be adjusted according to the size of the connecting component wrapped by the cable tie body, thereby adapting to connecting components of different sizes and expanding the application range of the flexible cable tie.

[0014] In some embodiments, a plurality of first locking teeth are disposed on the side of the cable tie body where the first locking portion and the second locking portion are disposed. The advantage of this arrangement is that, in the wrapped state, the plurality of first locking teeth are wound around the second end of the cable tie body to a position opposite to the first end of the cable tie body, thereby making the first locking teeth face the first locking portion and the second locking portion, which facilitates the connection between the first locking teeth and the first locking portion and the second locking portion.

[0015] In some embodiments, the cross-sectional shape of the cable tie body is arc-shaped in the width direction, and the first clamping part, the second clamping part, and the first clamping tooth are all disposed on the concave side of the cable tie body.

[0016] The advantage of setting the cross-sectional shape of the cable tie body to an arc shape, and setting the first clamping part, the second clamping part and the first clamping tooth on the concave side of the cable tie body, is that the cable tie body can form a shape in which the two sides wrap around the middle. When the cable tie body enters the wrapping state, it can protect the component wrapped by the cable tie body through its own winding characteristics, thereby improving the protection effect.

[0017] In some embodiments, the first card hole is provided with a second card tooth that engages with the first card tooth; and / or, the second card hole is provided with a third card tooth that engages with the first card tooth.

[0018] By setting a second locking tooth in the first locking hole and a third locking tooth in the second locking hole, the first locking tooth can cooperate with the second and third locking teeth to achieve a locking connection between the cable tie body and the first and second locking parts, which can effectively improve the stability and reliability of the locking connection.

[0019] In some embodiments, in a direction perpendicular to the cable tie body, the height of the first locking tooth is greater than the distance between the top of the second locking tooth in the first locking hole and the top wall of the first locking hole; and / or, the height of the first locking tooth is greater than the distance between the top of the third locking tooth in the second locking hole and the top wall of the second locking hole. This configuration prevents the first locking tooth from retracting after locking, effectively improving the stability and reliability of the locking connection.

[0020] In some embodiments, the width of the first locking tooth is greater than the width of the second locking tooth in the width direction of the cable tie body; and / or, the width of the first locking tooth is greater than the width of the third locking tooth. This arrangement effectively ensures the engagement of the first and second locking teeth, preventing the first locking tooth from deviating from its mating position with the second locking tooth and causing engagement failure; or, effectively ensures the engagement of the first and third locking teeth, preventing the first locking tooth from deviating from its mating position with the third locking tooth and causing engagement failure. Increasing the width of the first locking tooth effectively improves the stability of the connection.

[0021] In some embodiments, the portion of the first locking hole opposite to the second locking tooth is arc-shaped; and / or, the portion of the second locking hole opposite to the third locking tooth is arc-shaped. This allows the cable tie body to be wound into an arc shape after passing through the first and second locking holes, thereby providing a wrapping protection for the component wrapped by the cable tie body.

[0022] In some embodiments, the side of the first locking tooth is a right-angled triangle. By setting the first locking tooth to a right-angled triangle shape, a sliding mating surface can be formed, which facilitates the first locking tooth passing through the first locking hole and being blocked by the second locking tooth, or facilitates the first locking tooth passing through the second locking hole and being blocked by the third locking tooth. Setting the first locking tooth to a right-angled triangle shape also makes the adjacent surfaces of the sliding mating surface form vertical surfaces, which is beneficial to improving the blocking effect. Setting the first locking tooth to a right-angled triangle shape also helps to reduce the projected area of ​​the first locking tooth on the cable tie body, thereby allowing more first locking teeth to be arranged.

[0023] In some embodiments, the first clamping part is disposed near the first end of the cable tie body, and the second clamping part is disposed between the first clamping part and the first clamping tooth.

[0024] In some embodiments, the width of the second locking hole is smaller than the width of the cable tie body. The advantage of this arrangement is that the two sides of the cable tie body are compressed and bent towards the middle when passing through the second locking hole, thereby forming an arc shape, which provides better protection for the components wrapped in the cable tie body; moreover, the arched arc shape also helps to protect the connecting components in the vertical direction, preventing them from being injured by components falling from above.

[0025] In some embodiments, the width of the first slot is greater than or equal to the width of the second slot, and the two sides of the cable tie body are respectively attached to the sidewall of the first slot.

[0026] Setting the width w of the first locking hole to be greater than or equal to the width w of the second locking hole can increase the unfolded area of ​​the cable tie body within the first locking hole, thereby increasing the coverage and protection range of the cable tie body and preventing the connected parts wrapped by the cable tie body from being exposed and causing accidents such as electric shock.

[0027] In some embodiments, in the direction perpendicular to the cable tie body, the distance between the top wall of the first locking hole and the top surface of the first clamping part is less than the distance between the top wall of the second locking hole and the top surface of the second clamping part. The advantage of this arrangement is that the height of the cable tie body at the second clamping part is lower than its height at the first clamping part, resulting in the cable tie body forming an "8" shape after winding, effectively securing it. Furthermore, it increases the circumferential length of the wrapping around the connecting component, improving the stability of the wrapping.

[0028] Secondly, this application provides an electrical connection structure, including,

[0029] The first connector includes a first connecting portion and a second connecting portion;

[0030] The second connector includes a third connecting part and a fourth connecting part;

[0031] The first connecting structure is used to electrically connect the first connecting part and the third connecting part.

[0032] The second connecting structure, wherein the second connecting part and the fourth connecting part are electrically connected via the second connecting structure, and the first connecting structure and the second connecting structure are respectively located on both sides of the second clamping part; and

[0033] In the aforementioned flexible cable tie, when the cable tie body is in a wrapped state, the second end of the cable tie body away from the first end passes through the first locking hole and the second locking hole, and the first connecting structure is located between the first locking part, the second locking part and the cable tie body, and the second connecting structure is located between the second locking part and the cable tie body.

[0034] In the above embodiments, the first connecting portion and the second connecting portion can be connected to the positive and negative terminals of the battery body, respectively, and the third connecting portion and the fourth connecting portion can be connected to the positive and negative terminals of the electrical device, respectively. The first connecting structure and the second connecting structure are located on both sides of the second clamping portion, and the second clamping portion can achieve electrical isolation between the first connecting structure and the second connecting structure, preventing short circuits caused by electrical connection between the first connecting structure and the second connecting structure, and improving the safety of the electrical connection structure.

[0035] When the cable tie body enters the wrapped state, the cable tie body is wound up, and the second end of the cable tie body away from the first end is connected to the first clamping part and the second clamping part respectively. Moreover, the first connecting structure is located between the first clamping part, the second clamping part and the cable tie body, and the second connecting structure is located between the second clamping part and the cable tie body. In this way, the first connecting structure and the second connecting structure can be wrapped in the space enclosed by the cable tie body to protect the first connecting structure and the second connecting structure from external damage, or to prevent people or objects from touching the first connecting structure and the second connecting structure and causing electric shock accidents.

[0036] In some embodiments, the electrical connection structure further includes a first fixing member and a second fixing member. The first fixing member is used to fix the first connection structure to the cable tie body, and the second fixing member is used to fix the second connection structure to the cable tie body. By providing the first fixing member, the connection between the first connection structure and the cable tie body can be realized, that is, the connection between the first connecting part, the third connecting part, and the cable tie body can be realized. By providing the second fixing member, the connection between the second connection structure and the cable tie body can be realized, that is, the connection between the second connecting part, the fourth connecting part, and the cable tie body can be realized.

[0037] In some embodiments, the cable tie body has a first connecting hole and a second connecting hole. The first connecting hole is located between the first clamping portion and the second clamping portion, and the second connecting hole is located on the side of the second clamping portion away from the first clamping portion. A first fixing member passes through the first connecting structure and the first connecting hole to connect the first connecting portion, the third connecting portion, and the cable tie body. A second fixing member passes through the second connecting structure and the second connecting hole to connect the second connecting portion, the fourth connecting portion, and the cable tie body. By providing the first connecting hole and the second connecting hole on the cable tie body, with the first connecting hole located between the first clamping portion and the second clamping portion, and the second connecting hole located on the side of the second clamping portion away from the first clamping portion, the first connecting structure and the second connecting structure can be separated on both sides of the second clamping portion, achieving electrical isolation and preventing safety accidents such as short circuits.

Detailed Implementation

[0067] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0068] Currently, high-voltage connectors on lithium batteries mostly adopt a hard plastic protective cover structure. This protective cover is fixed in a designated position by structural limiting or bolt locking. The main function of the protective cover is to isolate the exposed high-voltage parts, preventing contact between the exposed high-voltage parts and personnel, thus avoiding electric shock accidents.

[0069] When the protective cover is fixed using a limiting structure, the large tolerance of the incoming hard plastic material can easily lead to problems with the size being too small or too large. If the size is too small, the protective cover cannot be locked onto the limiting structure, and the limiting fails. If the size is too large, the cover will not lock properly, and the protective cover will make abnormal noise as the battery pack shakes, leading to a decrease in customer satisfaction.

[0070] When the protective cover is fixed by bolts, it is prone to cracking due to its high brittleness, which increases manufacturing and labor costs.

[0071] To address the above problems, the inventors conducted extensive research and discovered that flexible cable ties can be used to fix high-voltage connectors. The tightness of the flexible cable ties can be adjusted appropriately according to the size of the connected components, thus avoiding the influence of the size of the protective cover. For example, the protective cover will not fail to limit the connection if it is too small, or it will not wobble if it is too large. Therefore, the reliability of the connection can be improved and the connection components can be prevented from shaking. Moreover, the protective cover will not crack due to bolted connections, which can save manufacturing and labor costs.

[0072] The flexible cable tie embodiments provided in this application can be applied to batteries to secure high-voltage connectors or other components to be connected. Besides batteries, the flexible cable tie embodiments provided in this application can also be applied to other devices, such as air conditioners and refrigerators.

[0073] The battery embodiments using flexible cable ties provided in this application can be used, but are not limited to, in electrical equipment such as vehicles, ships, or aircraft. A power system comprising the batteries disclosed in this application can be used to supply power to the electrical equipment. This improves the reliability of connections between connecting components and effectively extends battery life.

[0074] Electrical equipment can include, but is not limited to, mobile phones, portable devices, laptops, electric vehicles, electric cars, ships, spacecraft, electric toys, and power tools. For example, spacecraft include airplanes, rockets, space shuttles, and spacecraft. Electric toys include stationary or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys. Power tools include metal cutting power tools, grinding power tools, assembly power tools, and railway power tools, such as electric drills, electric grinders, electric wrenches, electric screwdrivers, electric hammers, impact drills, concrete vibrators, and electric planers.

[0075] For ease of explanation, the following embodiments will use a vehicle 100 as an example of an electrical device from some embodiments of this application.

[0076] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a vehicle 100 provided in some embodiments of this application. The vehicle 100 can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle.

The battery 10 provides electrical energy for the operation of the motor 30 and other components in the vehicle, and the controller 20 controls the operation of the motor 30, for example, to meet the power needs of the vehicle 100 during startup, navigation, and driving.

[0077] In some embodiments of this application, the battery 10 can not only serve as the operating power source for the vehicle 100, but also as the driving power source for the vehicle 100, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 100.

[0078] Please refer to Figure 2 , Figure 2This is an exploded view of a battery 10 provided in some embodiments of this application. The battery 10 includes a housing 1 and a battery body 2, with the battery body 2 housed within the housing 1. The housing 1 provides a receiving space for the battery body 2, and the housing 1 can adopt various structures. In some embodiments, the housing 1 may include a first cover 101 and a second cover 102, which overlap each other, collectively defining a receiving space for accommodating the battery body 2. The second cover 102 may be a hollow structure with one open end, while the first cover 101 may be a plate-like structure, with the first cover 101 covering the open side of the second cover 102, so that the first cover 101 and the second cover 102 collectively define the receiving space; alternatively, both the first cover 101 and the second cover 102 may be hollow structures with one open side, with the open side of the first cover 101 covering the open side of the second cover 102.

Multiple battery bodies 2 can be directly connected in series, parallel, or a combination thereof, and then the entire assembly of the multiple battery bodies 2 is housed within the casing 1. Alternatively, battery 10 can also consist of multiple battery bodies 2 first connected in series, parallel, or a combination thereof to form a battery module, and then these battery modules are connected in series, parallel, or a combination thereof to form a whole, which is then housed within the casing 1. Battery 10 may also include other structures; for example, battery 10 may also include a busbar component for realizing electrical connections between multiple battery bodies 2.

The battery body 2 is generally classified into three types according to its packaging method: cylindrical battery cells, cuboid / square battery cells, and pouch battery cells, and this disclosure does not limit this type either.

[0082] Please refer to Figures 3 to 5The figures shown are an exploded view, a structural schematic diagram after removing the cover, and a top view of the battery 10 provided in some embodiments of this application. The battery body 2 is disposed in the receiving cavity of the housing 1. The battery 10 includes a first connector 4 connected to the battery body 2. The first connector 4 is electrically connected to a second connector 5. The second connector 5 is used to connect to an electrical device to provide electrical energy to the electrical device.

[0083] The battery 10 also includes a fixing component 6. The first connector 4, the second connector 5 and the flexible cable tie 3 in the unfolded state are first connected by the fixing component 6, and then the flexible cable tie 3 is wound up, and the flexible cable tie 3 wraps up the connection part of the first connector 4, the second connector 5 and the flexible cable tie 3.

[0084] like Figure 6 As shown, the first connector 4 includes a first connecting part 41 and a second connecting part 42. The first connecting part 41 is provided with a first fixing hole 43, and the second connecting part 42 is provided with a second fixing hole 44.

[0085] In some embodiments, the first connecting part 41 is connected to the positive terminal of the battery body 2, and the second connecting part 42 is connected to the negative terminal of the battery body 2.

[0086] like Figure 7 As shown, the second connector 5 includes a third connecting part 51, a fourth connecting part 52, and a connecting body 55. Both the third connecting part 51 and the fourth connecting part 52 are connected to the connecting body 55. The connecting body 55 is connected to an electrical device. The third connecting part 51 is electrically connected to the first connecting part 41, and the fourth connecting part 52 is electrically connected to the second connecting part 42.

[0087] The third connecting part 51 is provided with a third fixing hole 53, and the fourth connecting part 52 is provided with a fourth fixing hole 54.

[0088] The third connecting part 51 and the first connecting part 41 can be electrically connected by welding, bonding or bolting, and the fourth connecting part 52 and the second connecting part 42 can be electrically connected by welding, bonding or bolting.

[0089] In some embodiments, the third connection portion 51 is connected to the positive terminal of the electrical device, and the fourth connection portion 52 is connected to the negative terminal of the electrical device.

[0090] like Figure 8 As shown, the fixing component 6 includes a first fixing member 61 and a second fixing member 62. The first fixing member 61 and the second fixing member 62 can be bolts or pins, etc.

[0091] like Figure 9 and Figure 10As shown, the flexible cable tie 3 is in the unfolded state. The first fixing member 61 passes through the first fixing hole 43, the third fixing hole 53 and the cable tie body 31 to connect the first connecting part 41, the third connecting part 51 and the cable tie body 31; the second fixing member 62 passes through the second fixing hole 44, the fourth fixing hole 54 and the cable tie body 31 to connect the second connecting part 42, the fourth connecting part 52 and the cable tie body 31.

[0092] like Figure 11 and Figure 12 As shown, the cable tie body 31 is wound up and its two ends are tied together, thereby wrapping the connection part of the first connector 4, the second connector 5 and the cable tie body 31 in the inner circle of the cable tie body 31, so as to achieve the protection of the first connector 4, the second connector 5 and the fixing component 6.

[0093] like Figures 13 to 15 As shown, in some embodiments provided in this application, the flexible cable tie 3 includes a cable tie body 31, a first clamping part 32 and a second clamping part 33. The first clamping part 32 and the second clamping part 33 are disposed at the first end of the cable tie body 31, and there is a preset distance between the first clamping part 32 and the second clamping part 33. The cable tie body 31 has an unfolded state. In the unfolded state, the first clamping part 32 and the second clamping part 33 are disposed on the same side of the cable tie body 31. In the wrapped state, the second end of the cable tie body 31 is connected to the first clamping part 32 and the second clamping part 33.

[0094] In the above embodiments, the flexible cable tie 3 includes two clamping parts, namely a first clamping part 32 and a second clamping part 33. These two clamping parts can be connected to the cable tie body 31 after the cable tie body 31 is wound up, thereby achieving double fixation of the cable tie body 31, effectively improving the connection stability and reliability of the flexible cable tie 3 itself, and preventing the flexible cable tie 3 from accidentally coming loose.

[0095] There is a preset distance between the first clamping part 32 and the second clamping part 33, so that the component to be connected can be set between the first clamping part 32 and the second clamping part 33, and the component to be connected can also be set between the second clamping part 33 and the second end of the cable tie body 31, so that the flexible cable tie 3 can wrap at least two components to be connected at the same time; moreover, the component to be connected set between the first clamping part 32 and the second clamping part 33 and the component to be connected set between the second clamping part 33 and the second end of the cable tie body 31 can be separated by the second clamping part 33, for example, so that electrical isolation or thermal isolation can be achieved between the two components to be connected, thereby meeting the isolation requirements between the components to be connected.

[0096] When the cable tie body 31 is in the unfolded state, the first clamping part 32 and the second clamping part 33 are located on the same side of the cable tie body 31. This allows at least two components to be connected to be placed on the same side of the cable tie body 31. Then, the components connected by the flexible cable tie 3 are wrapped in the wrapping space of the cable tie body 31 by the winding of the cable tie body 31, thereby achieving the protection of the components to be connected.

[0097] In some embodiments, the cable tie body 31 is made of insulating material. This design provides insulation protection for the components enclosed by the cable tie body 31, preventing electric shock accidents.

[0098] In some embodiments, the cable tie body 31 is provided with a plurality of first locking teeth 34 arranged along its length direction (L), the first clamping part 32 is provided with a first locking hole 321, the second clamping part 33 is provided with a second locking hole 331, and the plurality of first locking teeth 34 are connected to the first clamping part 32 through the first locking hole 321 and to the second clamping part 33 through the second locking hole 331.

[0099] In the above embodiments, the cable tie body 31 and the first clamping part 32 are connected by the cooperation of the first clamping tooth 34 and the first clamping hole 321, and the cable tie body 31 and the second clamping part 33 are connected by the cooperation of the first clamping tooth 34 and the second clamping hole 331. This can improve the convenience of connection and facilitate rapid connection.

[0100] When the flexible cable tie 3 needs to be tightened, the second end of the cable tie body 31 passes sequentially through the first locking hole 321 on the first locking part 32 and the second locking hole 331 on the second locking part 33. One or some of the multiple first locking teeth 34 engage with the first locking hole 321, and another or some of the multiple first locking teeth 34 engage with the second locking hole 331. By setting multiple first locking teeth 34, the locking position can be adjusted according to the size of the connecting component wrapped by the cable tie body 31, thereby adapting to connecting components of different sizes and expanding the applicability of the flexible cable tie 3.

[0101] In some embodiments, a plurality of first locking teeth 34 are disposed on the side of the cable tie body 31 where the first locking portion 32 and the second locking portion 33 are disposed. That is, in the unfolded state, the plurality of first locking teeth 34, the first locking portion 32 and the second locking portion 33 are all located on the same side of the cable tie body 31. The advantage of this arrangement is that, in the wrapped state, the plurality of first locking teeth 34 are wound around the second end of the cable tie body 31 to a position opposite to the first end of the cable tie body 31, thereby making the first locking teeth 34 face the first locking portion 32 and the second locking portion 33, which facilitates the connection between the first locking teeth 34 and the first locking portion 32 and the second locking portion 33.

[0102] like Figure 13 and Figure 14As shown, in some embodiments, the cross-sectional shape of the cable tie body 31 is arc-shaped in the width direction (W), and the first clamping part 32, the second clamping part 33 and the first clamping tooth 34 are all disposed on the concave side of the cable tie body 31.

[0103] The advantage of setting the cross-sectional shape of the cable tie body 31 to an arc shape, and having the first clamping part 32, the second clamping part 33 and the first clamping tooth 34 all located on the concave side of the cable tie body 31, is that the cable tie body 31 can form a shape in which the two sides wrap around the middle. When the cable tie body 31 enters the wrapping state, the components wrapped by the cable tie body 31 can be protected by the winding characteristics of the cable tie body 31 itself, thereby improving the protection effect.

[0104] In some embodiments, the first card hole 321 is provided with a second card tooth 322 that cooperates with the first card tooth 34; and / or, the second card hole 331 is provided with a third card tooth 332 that cooperates with the first card tooth 34.

[0105] By setting a second locking tooth 322 in the first locking hole 321 and a third locking tooth 332 in the second locking hole 331, the first locking tooth 34 can achieve a snap-fit ​​connection between the cable tie body 31 and the first locking part 32 and the second locking part 33 by cooperating with the second locking tooth 322 and the third locking tooth 332, which can effectively improve the stability and reliability of the snap-fit ​​connection.

[0106] In some embodiments, in a direction perpendicular to the cable tie body 31 (H), the height of the first locking tooth 34 is greater than the distance between the top of the second locking tooth 322 in the first locking hole 321 and the top wall of the first locking hole 321; and / or, the height of the first locking tooth 34 is greater than the distance between the top of the third locking tooth 332 in the second locking hole 331 and the top wall of the second locking hole 331. This configuration prevents the first locking tooth 34 from retracting after locking, effectively improving the stability and reliability of the locking connection.

[0107] In some embodiments, in the width direction (W) of the cable tie body 31, the width of the first locking tooth 34 is greater than the width of the second locking tooth 322; and / or, the width of the first locking tooth 34 is greater than the width of the third locking tooth 332. This arrangement effectively ensures the engagement of the first locking tooth 34 with the second locking tooth 322, preventing the first locking tooth 34 from deviating from its mating position with the second locking tooth 322 and causing a connection failure; or, effectively ensures the engagement of the first locking tooth 34 with the third locking tooth 332, preventing the first locking tooth 34 from deviating from its mating position with the third locking tooth 332 and causing a connection failure. By increasing the width of the first locking tooth 34, the stability of the connection can be effectively improved.

[0108] In some embodiments, the portion of the first card hole 321 opposite to the second card tooth 322 is arc-shaped; and / or, the portion of the second card hole 331 opposite to the third card tooth 332 is arc-shaped.

[0109] like Figure 13 and Figure 14 As shown, by setting the portion of the first locking hole 321 opposite to the second locking tooth 322 and the portion of the second locking hole 331 opposite to the third locking tooth 332 to be arc-shaped, the cable tie body 31 can be wound into an arc shape after passing through the first locking hole 321 and the second locking hole 331, thereby forming a wrapping protection effect on the component wrapped by the cable tie body 31.

[0110] In some embodiments, the first locking tooth 34 has a right-angled triangular shape on its side. By setting the first locking tooth 34 to a right-angled triangular shape on its side, a mating surface with a slope can be formed. This mating surface facilitates the first locking tooth 34 passing through the first locking hole 321 and being blocked by the second locking tooth 322, or facilitates the first locking tooth 34 passing through the second locking hole 331 and being blocked by the third locking tooth 332. Setting the first locking tooth 34 to a right-angled triangular shape on its side also makes the adjacent surfaces of the sloped mating surface form vertical surfaces, which is beneficial to improving the blocking effect. Setting the first locking tooth 34 to a right-angled triangular shape on its side also helps to reduce the projected area of ​​the first locking tooth 34 on the cable tie body 31, thereby allowing more first locking teeth 34 to be arranged.

[0111] In some embodiments, a first clamping portion 32 is disposed near a first end of the cable tie body 31, and a second clamping portion 33 is disposed between the first clamping portion 32 and the first clamping tooth 34. The first clamping portion 32 and the second clamping portion 33 are arranged at intervals along the length direction (L) of the cable tie body 31. The second clamping portion 33 is disposed on the side of the first clamping portion 32 away from the first end of the cable tie body 31.

[0112] In some embodiments, the width w2 of the second locking hole 331 is smaller than the width w0 of the cable tie body 31. The advantage of this arrangement is that the two sides of the cable tie body 31 are compressed and bent towards the middle when passing through the second locking hole 331, thereby forming an arc shape in the cable tie body 31, which provides better protection for the components wrapped in the cable tie body 31; moreover, the arched arc shape also helps to protect the connecting components in the vertical direction, preventing them from being injured by components falling from above.

[0113] In some embodiments, the width w1 of the first slot 321 is greater than or equal to the width w2 of the second slot 331, and the two sides of the cable tie body 31 are respectively attached to the sidewall of the first slot 321.

[0114] When the cable tie body 31 is wound, it first passes through the second locking hole 331 and then through the first locking hole 321. The width w1 of the first locking hole 321 is greater than or equal to the width w2 of the second locking hole 331. This allows the cable tie body 31 and the second locking hole 331 to fit together more tightly in the width direction (W) than the first locking hole 321 and the cable tie body 31 in the width direction (W). This improves the fit between the cable tie body 31 and the second locking hole 331 and reduces the requirement for the fit between the first locking hole 321 and the second locking hole 331.

[0115] Setting the width w1 of the first locking hole 321 to be greater than or equal to the width w2 of the second locking hole 331 can increase the unfolded area of ​​the cable tie body 31 within the first locking hole 321, thereby increasing the coverage and protection range of the cable tie body 31 and preventing the connected parts wrapped by the cable tie body 31 from being exposed and causing accidents such as electric shock.

[0116] In some embodiments, in a direction (H) perpendicular to the cable tie body 31, the distance between the top wall of the first locking hole 321 and the top surface of the first clamping part 32 is less than the distance between the top wall of the second locking hole 331 and the top surface of the second clamping part 33.

[0117] like Figure 16 and Figure 17 As shown, the distance between the top wall of the first locking hole 321 and the top surface of the first clamping part 32 is d1, and the distance between the top wall of the second locking hole 331 and the top surface of the second clamping part 33 is d2, where d1 < d2. The advantage of this arrangement is that the height of the cable tie body 31 at the second clamping part 33 is lower than the height at the first clamping part 32, resulting in the cable tie body 31 forming an "8" shape after winding, effectively securing it. Furthermore, it increases the circumferential length of the wrapping of the connecting parts by the cable tie body 31, improving the stability of the wrapping.

[0118] In some embodiments, the cable tie body 31 includes a first region 31a, a second region 31b, and a third region 31c arranged along the length direction (L). The second region 31b is located between the first region 31a and the third region 31c. A first clamping part 32 and a second clamping part 33 are both disposed in the first region 31a, and a first locking tooth 34 is disposed in the second region 31b. The surface of the third region 31c is substantially smooth. Making the surface of the third region 31c smooth allows for smoother passage of the cable tie body 31 through the first locking hole 321 of the first clamping part 32 and the second locking hole 331 of the second clamping part 33, improving the ease of connection between the cable tie body 31 and the first clamping part 32 and the second clamping part 33.

[0119] In some embodiments, the end of the third region 31c away from the second region 31b includes a rounded corner 313. By providing the rounded corner 313, the ease with which the cable tie body 31 passes through the first locking hole 321 and the second locking hole 331 can be further improved. Moreover, by providing the rounded corner 313, it is also possible to avoid causing puncture wounds to the operator.

[0120] In some embodiments, the cable tie body 31 includes a first portion and a second and a third portion located on both sides of the first portion in the width direction (W). The thickness of the first portion is greater than the thickness of the second and the third portions. This arrangement allows the second and third portions on both sides to deform more easily when the cable tie body 31 passes through the first and second locking holes 321 and 331, thereby forming an inwardly rolled shape. This allows the cable tie body 31 to stably wrap around the protective interface of the component it wraps, providing better protection. It also allows the sides of the cable tie body 31 to fit snugly against the walls of the first and second locking holes 321 and 331, improving the stability of the snap-fit ​​connection.

[0121] like Figure 18 As shown, the cable tie body 31 is provided with a first connecting hole 311 and a second connecting hole 312.

[0122] The first connecting hole 311 and the second connecting hole 312 can be round holes, elongated holes, or holes of other shapes. The first connecting hole 311 and the second connecting hole 312 can be used to connect the cable tie body 31 to the first connector 4 and the second connector 5, and can also be used to avoid protruding structures on the first connector 4 or the second connector 5.

[0123] The first connecting hole 311 is located between the first clamping part 32 and the second clamping part 33, and the second connecting hole 312 is located between the second clamping part 33 and the first locking tooth 34. The first connecting hole 311 and the second connecting hole 312 are symmetrically arranged on both sides of the second clamping part 33. This arrangement allows the two connecting parts of the first connector 4 and the two connecting parts of the second connector 5 to be connected to both sides of the second clamping part 33, achieving electrical isolation or thermal isolation, etc.

[0124] This application also provides an electrical connection structure, which includes a first connector 4, a second connector 5, a first connection structure, a second connection structure, and a flexible cable tie 3. The first connector 4 includes a first connection portion 41 and a second connection portion 42. The second connector 5 includes a third connection portion 51 and a fourth connection portion 52. The first connection portion 41 and the third connection portion 51 are electrically connected through the first connection structure, and the second connection portion 42 and the fourth connection portion 52 are electrically connected through the second connection structure. The first connection structure and the second connection structure are respectively located on both sides of the second clamping portion 33. When the cable tie body 31 is in a wrapped state, the first connection structure is located between the first clamping portion 32, the second clamping portion 33, and the cable tie body 31, and the second connection structure is located between the second clamping portion 33 and the cable tie body 31.

[0125] In the above embodiments, the first connector 4 includes two connecting portions, namely a first connecting portion 41 and a second connecting portion 42, and the second connector 5 includes two connecting portions, namely a third connecting portion 51 and a fourth connecting portion 52. The first connecting portion 41 and the second connecting portion 42 can be connected to the positive and negative terminals of the battery body 2, respectively, and the third connecting portion 51 and the fourth connecting portion 52 can be connected to the positive and negative terminals of the electrical device, respectively. The first connecting portion 41 and the third connecting portion 51 are electrically connected through a first connecting structure, and the second connecting portion 42 and the fourth connecting portion 52 are electrically connected through a second connecting structure. Moreover, the first connecting structure and the second connecting structure are located on both sides of the second clamping portion 33, so that the second clamping portion 33 can achieve electrical isolation between the first connecting structure and the second connecting structure, preventing short circuits caused by the electrical connection between the first connecting structure and the second connecting structure, and improving the safety of the electrical connection structure.

[0126] When the cable tie body 31 enters the wrapped state, the cable tie body 31 is wound up, and the second end of the cable tie body 31 away from the first end is connected to the first clamping part 32 and the second clamping part 33 respectively. Moreover, the first connecting structure is located between the first clamping part 32, the second clamping part 33 and the cable tie body 31, and the second connecting structure is located between the second clamping part 33 and the cable tie body 31. In this way, the first connecting structure and the second connecting structure can be wrapped in the space enclosed by the cable tie body 31 to protect the first connecting structure and the second connecting structure from external damage, or to prevent people or objects from touching the first connecting structure and the second connecting structure and causing electric shock accidents.

[0127] The specific structures of the first and second connecting structures can be selected in various ways. For example, the first connecting part 41 and the third connecting part 51 can be connected by welding, bonding or bolting, and the second connecting part 42 and the fourth connecting part 52 can be connected by welding, bonding or bolting.

[0128] In some embodiments, the electrical connection structure further includes a first fixing member 61 and a second fixing member 62, wherein the first fixing member 61 is used to fix the first connection structure to the cable tie body 31, and the second fixing member 62 is used to fix the second connection structure to the cable tie body 31.

[0129] By setting the first fastener 61, the first connecting structure and the cable tie body 31 can be connected, that is, the first connecting part 41, the third connecting part 51 and the cable tie body 31 can be connected; by setting the second fastener 62, the second connecting structure and the cable tie body 31 can be connected, that is, the second connecting part 42, the fourth connecting part 52 and the cable tie body 31 can be connected.

[0130] In some embodiments, the cable tie body 31 is provided with a first connecting hole 311 and a second connecting hole 312. The first connecting hole 311 is disposed between the first clamping part 32 and the second clamping part 33, and the second connecting hole 312 is disposed on the side of the second clamping part 33 away from the first clamping part 32. The first clamping part 32 is provided with a first locking hole 321, and the second clamping part 33 is provided with a second locking hole 331. The first fixing member 61 passes through the first connecting structure and the first connecting hole 311 to connect the first connecting part 41, the third connecting part 51, and the cable tie body 31. The second fixing member 62 passes through the second connecting structure and the second connecting hole 312 to connect the second connecting part 42, the fourth connecting part 52, and the cable tie body 31. In this embodiment, the first connecting structure includes a first fixing hole 43 disposed in the first connecting part 41 and a third fixing hole 53 disposed in the third connecting part 51. The second connecting structure includes a second fixing hole 44 disposed in the second connecting part 42 and a fourth fixing hole 54 disposed in the fourth connecting part 52.

[0131] By providing a first connecting hole 311 and a second connecting hole 312 on the cable tie body 31, with the first connecting hole 311 located between the first clamping part 32 and the second clamping part 33, and the second connecting hole 312 located on the side of the second clamping part 33 away from the first clamping part 32, the first connecting structure and the second connecting structure can be separated on both sides of the second clamping part 33, achieving electrical isolation and preventing safety accidents such as short circuits.

[0132] In other embodiments, the first connection structure includes a first fixing hole 43 disposed in the first connection portion 41, a third fixing hole 53 disposed in the third connection portion 51, and a first fixing member 61. The first connection portion 41 and the third connection portion 51 are electrically connected through the first fixing member 61 passing through the first fixing hole 43 and the third fixing hole 53. Furthermore, the first fixing member 61 also passes through the first connection hole 311 disposed on the cable tie body 31, thereby realizing the connection between the first connection portion 41, the third connection portion 51, and the cable tie body 31. The second connection structure includes a second fixing hole 44 disposed in the second connection portion 42, a fourth fixing hole 54 disposed in the fourth connection portion 52, and a second fixing member 62. The second connection portion 42 and the fourth connection portion 52 are electrically connected through the second fixing member 62 passing through the third fixing hole 53 and the fourth fixing hole 54. Furthermore, the second fixing member 62 also passes through the second connection hole 312 disposed on the cable tie body 31, thereby realizing the connection between the second connection portion 42, the fourth connection portion 52, and the cable tie body 31.

[0133] This application also provides a battery, which includes a housing 1, a battery body 2 and an electrical connection structure. The housing 1 has an internal cavity, and the side wall of the housing 1 has a first through hole 11 communicating with the cavity. The battery body 2 is disposed in the cavity. A first connector 4 is electrically connected to the battery body 2. A second connector 5 is disposed outside the housing 1. A third connector 51 and a fourth connector 52 pass through the first through hole 11 and are connected to the first connector 4. The electrical connection structure is disposed in the cavity.

[0134] In the battery embodiment provided in this application, the battery body 2 and the power device are connected by an electrical connection structure. The first connector 4 located inside the battery casing 1 is electrically connected to the second connector 5 that extends into the casing 1 through the first through hole 11, and is connected and wrapped by a flexible cable tie 3. Thus, the connection part of the first connector 4 and the second connector 5 can be safely protected by the flexible cable tie 3, thereby improving the safety of battery use.

[0135] In the battery embodiment provided in this application, the second connector 5 may include a high-voltage connector. This embodiment abandons the approach of protecting the high-voltage connector with a hard plastic protective cover, as used in related technologies, and instead employs a flexible cable tie 3 to protect the high-voltage connector. This overcomes problems such as limiting failure, shaking, and easy cracking of the protective cover caused by manufacturing errors or high brittleness of the high-voltage connector's protective cover.

[0136] The following is in conjunction with the appendix Figures 3 to 18 The structures of some embodiments of the battery, electrical connection structure, and flexible cable tie provided in this application will be described below:

[0143] like Figure 9 and Figure 10 As shown, the flexible cable tie 3 is in the unfolded state; Figure 11 and Figure 12 As shown, the flexible cable tie 3 is in a wrapped state. The second end of the cable tie body 31, which is away from the first end, is wound and connected to the first clamping part 32 and the second clamping part 33. The first connecting structure is located between the first clamping part 32, the second clamping part 33 and the cable tie body 31, and the second connecting structure is located between the second clamping part 33 and the cable tie body 31.

[0144] like Figures 13 to 15 As shown, the flexible cable tie 3 includes a cable tie body 31. The cable tie body 31 includes a first region 31a, a second region 31b, and a third region 31c along its length direction (L). The second region 31b is located between the first region 31a and the third region 31c. The end of the first region 31a away from the second region 31b is the first end of the cable tie body 31, and the end of the third region 31c away from the second region 31b is the second end of the cable tie body 31.

[0145] The first clamping part 32 and the second clamping part 33 are both disposed in the first region 31a of the cable tie body 31. The second region 31b of the cable tie body 31 is provided with a plurality of first clamping teeth 34 arranged along the length direction (L). The third region 31c is smooth. The second end of the cable tie body 31 is provided with a rounded corner 313.

[0146] A first clamping part 32 is disposed at the first end of the cable tie body 31, and the side of the first clamping part 32 is flush with the end face of the first end of the cable tie body 31. A second clamping part 33 is disposed between the first clamping part 32 and the first clamping tooth 34. There is a preset distance between the first clamping part 32 and the second clamping part 33. There is a preset spacing between two adjacent first clamping teeth 34.

[0147] In the width direction (W) of the cable tie body 31, the cross-sectional shape of the cable tie body 31 is arc-shaped, and the first clamping part 32, the second clamping part 33 and the first clamping tooth 34 are all provided on the concave side of the cable tie body 31.

[0148] The first clamping part 32 is provided with a first clamping hole 321, and the second clamping part 33 is provided with a second clamping hole 331. The first clamping hole 321 is provided with a second clamping tooth 322 that cooperates with the first clamping tooth 34, and the second clamping hole 331 is provided with a third clamping tooth 332 that cooperates with the first clamping tooth 34.
