[0002] This section merely provides background information related to the present application and is not necessarily prior art.

[0003] The wiring structure can integrate multiple wires such as conductors or communication lines, reduce the clutter of the core wires, improve the convenience of wiring, and facilitate the miniaturization of electrical devices. At present, due to the differences in line arrangement and current carrying requirements of electrical devices, the number and length of the core wires of the wiring structure are also different. During the use of the wiring structure, it is often necessary to separate some of the core wires of the wiring structure to suit the current electrical device. However, during the separation process of the wiring structure, it is easy to have a significant impact on the performance of the wiring structure. Utility Model Content

[0004] In view of the above problems, the present application provides a wiring structure, a battery device and an electrical device to at least alleviate the problem that the performance is easily damaged when the wiring structure is separated.

[0005] The first aspect of the present application proposes a wiring arrangement structure, which includes a plurality of core wires arranged at intervals and an integrally constructed connecting layer, the connecting layer including a connecting section and a plurality of wrapping parts, the outer sides of the plurality of core wires are coated with the wrapping parts, two adjacent wrapping parts are connected by the connecting section, a separation guide part is provided on the connecting section, the separation guide part is used to locate the separation position of the connecting section; along the arrangement direction of the two adjacent core wires, the separation guide part is provided in the middle part of the connecting section, and the thickness of the connecting section is reduced along the direction from the wrapping part to the middle part of the connecting section.

[0006] In the technical solution of the embodiment of the present application, by setting a separation guide on the connection section, when the cable arrangement structure needs to separate part of the core wires, the connection section can be separated along the separation guide between the core wire to be separated and the adjacent core wire, so that the corresponding core wire and the wrapping part that wraps the core wire are separated together, which improves the convenience of the cable arrangement separation operation, and under the guidance of the separation guide, the accuracy of the separation position of the core wire connection section can be improved, and the possibility of the wrapping part being damaged due to the deviation of the separation position, thereby affecting the performance of the cable arrangement structure, is reduced. By setting the separation guide in the middle of the connection section, and the thickness of the connection section is reduced along the direction from the wrapping part to the middle of the connection section, the farther the connection section is from the separation guide, the higher its strength is, and the possibility of the wrapping part being damaged due to the deviation of the separation position to the wrapping part, thereby affecting the performance of the cable arrangement structure, can be further reduced.

[0007] In addition, the cable arrangement structure of the present application may also have the following additional technical features:

[0008] In some embodiments of the present application, the separation guide extends along the length direction of the core wire and is continuously arranged along the length direction of the core wire; or, the separation guide includes a plurality of sub-parts arranged in a straight line along the length direction of the core wire, each of the sub-parts extends in the length direction of the core wire, and the plurality of sub-parts are arranged at intervals. The separation guide extends along the length direction of the core wire, and can locate the separation position of the connection segment in the length direction of the core wire, thereby improving the accuracy of the separation position of the core wire connection segment and reducing the possibility of damage to the wrapping part due to the deviation of the separation position, thereby affecting the performance of the cable arrangement structure.

[0009] In some embodiments of the present application, the tear strength of the area corresponding to the connection section and the separation guide portion is lower than the tear strength of other areas of the connection section. The operator can apply a tearing force to the connection section to tear the core wire along the separation guide portion, which is convenient to operate and can reduce the possibility of affecting the performance of the cable arrangement structure due to damage to the wrapping portion caused by the separation position offset.

[0010] In some embodiments of the present application, the thickness of the area corresponding to the connection section and the separation guide portion is less than the thickness of other areas of the connection section. By setting the thickness of the area corresponding to the connection section and the separation guide portion to be less than the thickness of other areas of the connection section, the tear strength of the area corresponding to the connection section and the separation guide portion is less than the tear strength of other areas of the connection section. The operator can apply a tearing force to the connection section to tear the core wire along the separation guide portion, which is convenient to operate and can reduce the possibility of affecting the performance of the cable arrangement structure due to damage to the wrapping portion caused by the displacement of the separation position.

[0011] In some embodiments of the present application, the separation guide is configured as a groove extending along the length direction of the core wire. The separation guide in the form of a groove can be used as a positioning structure. When the operator uses a tool to cut, the tool can be inserted into the groove, and the groove can locate the position of the tool, further improving the accuracy of the core wire separation operation; the groove can also be used as an obvious indicator. After the core wire separation is completed, by observing the separation of the groove, it is relatively convenient to judge whether the core wire separation has a large deviation, thereby reducing the problem of unqualified core wires being mistakenly assembled and affecting the quality of electrical devices.

[0012] In some embodiments of the present application, the separation guide is configured as an arc groove, a V-shaped groove or a U-shaped groove. The separation guide is configured as an arc groove or a V-shaped groove, which is convenient for processing and easy demoulding if an injection molding process is adopted; at the same time, the groove structure of these shapes can form the weakest position at the bottom of the groove, so that the connection section can be separated along the bottom of the groove, thereby realizing the separation of the core wire, and further improving the operational accuracy of the core wire separation.

[0013] In some embodiments of the present application, the connecting section has a first surface and a second surface that are oppositely arranged along a first direction, and along the direction from the wrapping portion to the middle portion of the connecting section, the first surface and the second surface are respectively oriented toward each other to approach each other, so that the thickness of the connecting section is reduced, and the first direction, the length direction of the core wire, and the arrangement direction intersect each other. The two oppositely arranged surfaces of the connecting section are gradually tapered toward the middle portion, so that both surfaces of the connecting section can be used as separation starting surfaces, which is easy to operate, and can make the connecting section and the corresponding area of ​​the separation guide portion have a smaller thickness while maintaining the connection strength of the connecting section, thereby reducing the difficulty of separation.

[0014] In some embodiments of the present application, the separation guides are respectively provided on two opposite sides of the connection section in the first direction, and the separation guides on the two sides are arranged opposite to each other along the first direction, and the first direction, the length direction of the core wires, and the arrangement direction of two adjacent core wires intersect each other. By providing separation guides on both sides of the connection section, both sides of the connection section can have a separation guide function, and the core wires can be separated from any side of the connection section, which is convenient for operation. And in some implementations, for example, when the separation guide is set as a groove, the thickness of the corresponding area of ​​the connection section and the separation guide can be further reduced, reducing the difficulty of separation.

[0015] In some embodiments of the present application, along the first direction, the two opposite sides of the wrapping portion are both protruding relative to the connecting section, the connecting section has a first side and a second side oppositely arranged along the first direction, the first side is connected to the corresponding side of the wrapping portion in an arcuate and smooth manner, the second side is connected to the corresponding side of the wrapping portion in an arcuate and smooth manner, the arrangement direction of the wrapping portion and the connecting section, the length direction of the core wire and the first direction intersect each other. The arcuate transition connection between the connecting section and the wrapping portion can improve the connection strength of the connecting section and the wrapping portion at the connection position, and is convenient for demolding when the injection molding process is used.

[0016] A second aspect of the present application provides a battery device, which includes the wiring structure provided in the present application or any embodiment of the present application.

[0017] In some embodiments of the present application, the connected layer is configured as an insulating member.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0040] The wiring structure can integrate multiple wires or communication wires, and can be used for connecting electrical devices such as mobile components and main boards, main boards (e.g., PCB boards, i.e., printed circuit boards) and main boards, and miniaturized electrical appliances. The wiring structure can select the number and spacing of core wires as needed, making connection more convenient, greatly reducing the size of electrical devices, reducing production costs, and improving production efficiency. In battery devices, the wiring structure can be used in scenarios where voltage, temperature, and other information of battery cells are sampled.

[0041] During the assembly of the battery device, it is often necessary to separate part of the core wires of the wiring structure according to the actual assembly situation so that each core wire can be connected in place. For example, when the corresponding core wires of the wiring structure are inconsistent with the hole spacing of the connecting device, the connected part of the wiring structure needs to be torn. In the process of separating the core wires, the outer wrapping layer of the core wire is often damaged due to the offset of the split position, resulting in the core wire being exposed, and even directly damaging the core wire, which affects the performance of the wiring structure, not only causing the wiring structure to be scrapped, increasing production costs, and reducing assembly efficiency, but also there is a possibility of misusing the wiring structure with unqualified performance and affecting the quality of the battery device.

[0042] Based on the above situation, in order to alleviate the problem that the performance of the wiring structure is easily damaged during the separation process, the present application provides a wiring structure, in which a separation guide is provided on the connection section between the wrapping parts of two adjacent core wires. The separation guide can play a role in separation guidance. When the wiring structure needs to separate some core wires, the connection section can be separated along the separation guide between the core wire to be separated and the adjacent core wire, so that the corresponding core wire and the wrapping part wrapping the core wire are separated together, which improves the convenience of the wiring separation operation. Under the guidance of the separation guide, the accuracy of the separation position of the core wire connection section can be improved, and the possibility of the separation position offset causing the wrapping part to be damaged or the core wire to be damaged, thereby affecting the performance of the wiring structure, is reduced. In the production process of electrical devices such as battery devices using the wiring structure, the scrap rate of the wiring structure is reduced, the production cost is reduced, the assembly efficiency of the electrical device is improved, and the quality of the electrical device is also improved.

[0043] The wiring structure proposed in this application or in the embodiments of this application can be connected to the battery cell of the battery device to collect information such as the temperature and pressure of the battery cell. The wiring structure can also be applied to other positions of the battery device that require multi-line connection. Naturally, the wiring structure proposed in this application or in the embodiments of this application can also be applied to other electrical devices, such as electrical equipment such as vehicles, ships or aircraft.

[0044] The battery device proposed in the present application or the embodiments of the present application can be used in, but not limited to, electrical equipment such as vehicles, ships or aircraft. The battery device can be used as a power source for electrical equipment, and the electrical equipment can be, but not limited to, mobile phones, tablets, laptops, electric toys, electric tools, battery cars, electric cars, ships, spacecraft, etc. Among them, electric toys can include fixed or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc., and spacecraft can include airplanes, rockets, space shuttles, and spacecraft, etc.

[0045] For the convenience of description, the following embodiments are mainly described by taking the application of the wiring structure to a battery device as an example.

[0046] like Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of a battery device proposed in some embodiments of the present application. The battery device 10 mentioned in the embodiments of the present application may include one or more battery cell assemblies 11 for providing voltage and capacity. The battery cell assembly 11 may include a plurality of battery cells 20, and the plurality of battery cells 20 are connected in series, in parallel, or in mixed connection through a busbar 12.

[0047] In some embodiments, the battery cell assembly 11 is generally formed by arranging a plurality of battery cells 20 .

[0048] As an example, the battery cell assembly 11 may be a battery module, which is formed by arranging and fixing a plurality of battery cells 20 to form an independent module. As an example, the battery module may be formed by bundling a plurality of battery cells 20 by a cable tie.

[0049] In some embodiments, the battery device 10 may be a battery pack, which includes a case 13 and one or more battery cell assemblies 11 , wherein the battery cell assemblies 11 are accommodated in the case 13 .

[0050] As an example, the battery cell assembly 11 may be a battery module, and the battery cell assembly 11 may be accommodated in the box body 13 by fixing the battery module in the box body 13 .

[0051] As an example, the battery cell assembly 11 may also be accommodated in the case 13 by directly fixing the plurality of battery cells 20 to the case 13 .

[0052] As an example, the box 13 may include a first box 131 and a second box 132. The first box 131 and the second box 132 are buckled together to form a closed space inside the box 13 to accommodate the battery cell assembly 11. The closed space here means covering or closing, which can be sealed or unsealed. The first box 131 can be a top cover or a bottom plate.

[0053] As an example, the box body 13 may include a top cover, a frame and a bottom plate. The top cover and the bottom plate are respectively connected to the frame, so that a closed space is formed inside the box body 13 to accommodate the battery cell assembly 11.

[0055] In the embodiment of the present application, the battery cell 20 may be a secondary battery. A secondary battery refers to a battery cell 20 that can be continuously used by activating active materials by charging after the battery cell 20 is discharged.

[0057] like Figure 2 As shown, Figure 2This is a schematic diagram of a battery cell proposed in some embodiments of the present application. The battery cell 20 may include an electrode assembly 22 and a shell 21. The electrode assembly 22 is arranged in the shell 21, including a positive electrode, a negative electrode and a separator, and the separator is arranged between the negative electrode and the positive electrode; the electrode assembly 22 is provided with a pole ear 221, and the pole ear 221 can lead the current from the electrode assembly 22. The pole ear 221 includes a positive pole ear and a negative pole ear. At least one electrode terminal 213 is arranged on the shell 21, and the electrode terminal 213 is electrically connected to the pole ear 221. The electrode terminal 213 can be directly connected to the pole ear 221, and can also be indirectly connected to the pole ear 221 through a current collecting member. The shell 21 includes a shell 211 with an opening and an end cover 212 covering the opening. The electrode terminal 213 can be arranged on the end cover 212 or on the shell 211.

[0058] like Figure 1 , and combined with Figure 3 As shown, Figure 3 The schematic diagram of the connection between the wiring structure and the busbar component proposed in some embodiments of the present application; it also includes a sampling component and a battery management system, the battery management system is BMS (Battery Management System), which can intelligently manage and maintain each battery cell 20, reduce the possibility of overcharging and overdischarging of the battery device 10, extend the service life of the battery device 10, monitor the status of the battery device 10, etc. The sampling component includes a sampler 30 and a wiring structure 100, the sampler 30 is connected to the battery management system, namely BMS (Battery Management System), one end of the core wire 110 of the wiring structure 100 is connected to the sampler 30, and the other end of the core wire 110 of the wiring structure 100 can be connected to the electrode terminal 213 of the battery cell 20 through the busbar component 12, wherein the electrode terminal of each battery cell 20 can be connected to the core wire 110 through the busbar component 12. The sampling component is used to collect temperature and / or voltage information of the battery cell 20, which is transmitted in the sampling component in the form of a signal, and the sampler 30 transmits the collected signal to the battery management system.

[0059] like Figure 3 , and combined with Figure 4 As shown, Figure 4 This is a schematic diagram of a cable arrangement structure from one perspective proposed in some embodiments of the present application. This embodiment provides a cable arrangement structure 100, including a plurality of core wires 110 arranged at intervals and an integrally constructed connected layer 120, the connected layer 120 includes a connecting section and a plurality of wrapping portions 121, the outer sides of the plurality of core wires 110 are all coated with a wrapping portion 121, two adjacent wrapping portions 121 are connected by a connecting section 122, a separation guide portion 126 is provided on the connecting section 122, and the separation guide portion 126 is used to locate the separation position of the connecting section 122.

[0060] The core wire 110 may be a wire used by the cable arrangement structure 100 to electrically connect to an electrical component, and may be a conductor, specifically a core of a conductive wire, a core of a communication wire, etc. The core wire 110 may be a wire with a circular cross section, and in some other embodiments, the core wire 110 may also be a wire with a polygonal, irregular, elliptical, or other cross section as required.

[0061] The integrally constructed conjoined layer 120 can be understood as an integral structure of the wrapping portion 121 and the connecting section 122. The conjoined layer 120 is a structure that connects multiple core wires 110 into one, which can be processed into an integral structure, specifically, an integral structure formed by a molding process such as injection molding.

[0062] In some implementations, the core wire 110 can be wrapped and fixed during the molding process of the connecting layer 120. For example, the core wire 110 is first placed in a mold at a predetermined position, and then the mold is injected to form slurry, so that the slurry is wrapped around the outside of the core wire 110 to form the connecting layer 120.

[0063] The wrapping portion 121 can be wrapped around the outside of the core wire 110. Along the length direction X of the core wire 110, the wrapping portion 121 covers at least a portion of the length of the core wire 110. Along the circumference of the core wire 110, the wrapping portion 121 can cover the entire outer peripheral surface of the corresponding area of ​​the core wire 110. The wrapping portion 121 of the conjoined layer 120 can make multiple core wires 110 relatively spaced apart, reducing the possibility of mutual influence between the core wires 110. Exemplarily, the conjoined layer 120 can be an insulating part made of insulating material, such as plastic, rubber, resin, etc., to achieve a better insulation and isolation effect.

[0064] The connecting section 122 is a portion of the connected layer 120 located between two adjacent wrapping portions 121 , and the connecting section 122 connects the two adjacent wrapping portions 121 into an integral structure.

[0065] The separation guide portion 126 is a component used to guide and position the separation position of the connecting segment 122, wherein when two adjacent core wires 110 of the connecting segment 122 need to be separated, the connecting segment 122 needs to be at least partially disconnected, and the separation position positioned by the separation guide portion 126 is a more ideal disconnection position of the connecting segment. When the connecting segment 122 is disconnected at the separation position positioned by the separation guide portion 126, the wrapping portions 121 at both ends of the connecting segment 122 can better retain their integrity.

[0066] Exemplarily, the separation guide portion 126 may extend along the length direction X of the core wire 110 .

[0067] Exemplarily, the separation guide 126 may be a separation marking line provided on the surface of the connection section 122. By cutting or cutting tools, the connection section 122 may be separated along the separation marking line to separate the corresponding core wire 110. Exemplarily, the separation guide 126 may also be a weak structure. Compared with other positions of the connection section 122, the separation guide 126 is easier to be damaged. When the operator applies a destructive force (such as a tearing force, etc.) to the connection section 122, the connection section 122 may be separated along the separation guide 126.

[0068] It should be noted that the separation length of the core wire 110 can be determined as needed, that is, the connecting section 122 can be divided into two independent parts along the separation guide 126, or only part of the connecting section 122 can be separated along the separation guide 126.

[0069] By providing a separation guide portion 126 on the connecting section 122, when the cable arrangement structure 100 needs to separate part of the core wires 110, the connecting section 122 can be separated along the separation guide portion 126 between the core wire 110 to be separated and the adjacent core wire 110, so that the corresponding core wire 110 and the wrapping portion 121 wrapping the core wire 110 are separated together, thereby improving the convenience of the cable separation operation. Under the guidance of the separation guide portion 126, the accuracy of the separation position of the connecting section 122 can be improved, reducing the possibility of damage to the wrapping portion 121 due to the deviation of the separation position, thereby affecting the performance of the cable arrangement structure 100.

[0070] According to some embodiments of the present application, optionally, the separation guide portion 126 extends along the length direction X of the core wire 110 and is continuously arranged along the length direction X of the core wire 110; or, the separation guide portion 126 includes a plurality of sub-portions arranged in a straight line along the length direction X of the core wire 110, each sub-portion extends along the length direction X of the core wire 110, and the plurality of sub-portions are arranged at intervals.

[0071] Exemplarily, the separation guide 126 may extend along the length direction X of the core wire 110 and may be continuously disposed along the length direction X of the core wire 110. That is, along the length direction X of the core wire 110, the separation guide 126 is a continuous structure, for example, the separation guide 126 may extend continuously from one end of the connecting section 122 along the length direction X of the core wire 110 to the other end.

[0072] Exemplarily, the separation guide 126 may also include a plurality of sub-portions arranged in a straight line along the length direction X of the core wire 110, each sub-portion extending in the length direction X of the core wire 110, and the plurality of sub-portions are arranged at intervals. That is, along the length direction X of the core wire 110, the separation guide 126 may be arranged to extend intermittently, for example, the separation guide 126 may extend intermittently in the form of a dotted line from one end of the connecting section 122 to the other end along the length direction X of the core wire 110.

[0073] The separation guide portion 126 extends continuously or intermittently along the length direction X of the core wire 110, so that the separation guide portion 126 can play a better guiding role in the length direction of the core wire 110, thereby improving the accuracy of the separation position of the connecting section 122 and reducing the possibility of damage to the wrapping portion 121 due to separation position deviation, thereby affecting the performance of the wiring structure 100.

[0074] According to some embodiments of the present application, optionally, the tear strength of the corresponding area of ​​the connecting segment 122 and the separation guide portion 126 (understood with reference to the guide segment 123 ) is smaller than the tear strength of other areas of the connecting segment 122 (understood with reference to the first side segment 124 and the second side segment 125 ).

[0075] The connecting section 122 can be made of a soft material that is easily torn, such as resin, plastic, rubber, silicone, etc., which have relatively weak rigidity.

[0076] Tear strength refers to the material's ability to resist tearing force. The smaller the tear strength, the easier it is to tear.

[0077] The other areas of the connecting section 122 refer to the areas of the connecting section 122 located outside the area corresponding to the separation guide portion 126. Exemplarily, the connecting section 122 includes a first side section 124, a guide section 123 and a second side section 125 connected in sequence, the separation guide portion 126 is arranged in the guide section 123, the guide section 123 is the area corresponding to the separation guide portion 126, and the first side section 124 and the second side section 125 are other areas of the connecting section 122.

[0078] Exemplarily, the connecting section 122 can be designed to reduce the thickness h of the area where the separation guide portion 126 is located, so that the tear strength of the corresponding area of ​​the connecting section 122 and the separation guide portion 126 (refer to the guide section 123 for understanding) is less than the tear strength of other areas of the connecting section 122 (refer to the first side section 124 and the second side section 125 for understanding).

[0079] Exemplarily, the connecting section 122 may also be provided with microstructures such as tear marks or lines on the connecting section 122 to form a separation guide portion 126, so that the separation guide portion is easier to tear, thereby making the tear strength of the corresponding area of ​​the connecting section 122 and the separation guide portion 126 (refer to the guide section 123 for understanding) less than the tear strength of other areas of the connecting section 122.

[0080] In some other implementations, other areas of the connecting segment 122 and the corresponding areas of the connecting segment 122 and the separation guide portion 126 (refer to the guide segment 123 for understanding) may also use different materials to make the tear strength of the corresponding areas of the connecting segment 122 and the separation guide portion 126 (refer to the guide segment 123 for understanding) smaller than the tear strength of other areas of the connecting segment 122 (refer to the first side segment 124 and the second side segment 125).

[0081] By setting the tear strength of the corresponding area of ​​the connecting section 122 and the separation guide portion 126 (refer to the guide section 123) to be smaller than the tear strength of other areas of the connecting section 122 (refer to the first side section 124 and the second side section 125), the operator can apply a tearing force to the connecting section 122 to tear the core wire 110 along the separation guide portion 126, which is easy to operate and can reduce the possibility of affecting the performance of the cable arrangement structure 100 due to damage to the wrapping portion 121 due to the offset of the separation position.

[0082] According to some embodiments of the present application, optionally, Figure 4 As shown, the thickness h of the area corresponding to the connecting section 122 and the separation guide portion 126 is smaller than the thickness H of other areas of the connecting section 122 .

[0083] The thickness of the connecting section 122 also refers to the size of the connecting section 122 along the first direction Z. The thickness h of the area corresponding to the connecting section 122 and the separation guide 126 refers to the size of the position of the connecting section 122 where the separation guide 126 is provided, along the first direction Z; the thickness H of other areas of the connecting section 122 refers to the size of the area of ​​the connecting section 122 that avoids the separation guide 126, along the first direction Z. The first direction Z intersects with the arrangement direction Y of the two adjacent core wires 110 connected by the connecting section 122, and also intersects with the length direction X of the core wire 110. Exemplarily, the first direction Z, the arrangement direction Y and the length direction X of the core wire 110 may be substantially perpendicular to each other.

[0084] The thickness h of the area corresponding to the connecting section 122 and the separation guide portion 126 is smaller than the thickness H of other areas. The minimum thickness of the area corresponding to the connecting section 122 and the separation guide portion 126 can be smaller than the minimum thickness of other areas of the connecting section 122. That is, the thickness of the separation guide portion 126 is the area with the smallest thickness in the connecting section 122.

[0085] The area corresponding to the connecting section 122 and the separation guide portion 126 is defined as the guide section 123, and other areas of the connecting section 122 may include a first side section 124 and a second side section 125 located on both sides of the separation guide portion 126 (guide section 123) along the arrangement direction Y of the two adjacent core wires 110, and the thickness of the first side section 124 and the thickness of the second side section 125 are both greater than the thickness of the guide section 123.

[0086] The other regions of the connecting section 122 (including the first side section 124 and the second side section 125 ) and the separation guide portion 126 may be made of the same material and may be integrally injection molded.

[0087] By setting the thickness h of the area corresponding to the connecting section 122 and the separation guide portion 126 (i.e., the guide section 123) to be smaller than the thickness H of other areas of the connecting section 122 (i.e., the first side section 124 and the second side wall), the tear strength of the area corresponding to the connecting section 122 and the separation guide portion 126 is made smaller than the tear strength of other areas of the connecting section 122. The operator can tear the core wire 110 along the separation guide portion 126 by applying a tearing force to the connecting section 122, which is easy to operate and can reduce the possibility of affecting the performance of the cable arrangement structure 100 due to damage of the wrapping portion 121 due to the displacement of the separation position.

[0088] According to some embodiments of the present application, optionally, Figure 4 and Figure 5 As shown, Figure 5 for Figure 4 In the partially enlarged view, the separation guide portion 126 is configured as a groove extending along the length direction X of the core wire 110.

[0089] The groove refers to a groove structure that is recessed inward relative to the surface of other regions of the connecting section 122 , and the groove can be set to any shape.

[0090] By providing a groove as a separation multi-lead portion, the thickness h of the area corresponding to the connecting section 122 and the separation guide portion 126 (i.e., the guide section 123) can be made smaller than the thickness H of other areas of the connecting section 122 (i.e., the first side section 124 and the second side section 125), so that the tear strength of the area corresponding to the connecting section 122 and the separation guide portion 126 is smaller than the tear strength of other areas of the connecting section 122. The operator can apply a tearing force to the connecting section 122 to tear the core wire 110 along the separation guide portion 126, which is easy to operate and can reduce the possibility of the separation position being offset and causing the wrapping portion 121 to be damaged, thereby affecting the performance of the cable arrangement structure 100. At the same time, the separation guide 126 in the form of a groove can be used as a positioning structure. When the operator uses a tool to cut, the tool can be inserted into the groove, and the groove can locate the position of the tool, further improving the operational accuracy of the separation of the core wire 110; the groove can also be used as an obvious indicator. After the separation of the core wire 110 is completed, by observing the separation of the groove, it is relatively convenient to judge whether a large deviation has occurred in the separation of the core wire 110, thereby reducing the problem of unqualified core wires 110 being incorrectly assembled and affecting the quality of electrical devices.

[0091] According to some embodiments of the present application, optionally, the separation guide portion 126 is configured as an arc-shaped groove or a V-shaped groove.

[0092] For example, Figure 4 and Figure 5 As shown, the groove can be configured as an arc-shaped groove.

[0093] Exemplarily, the groove may also be configured as a V-shaped groove.

[0094] An arc groove refers to a groove structure in which the cross section of the groove (the cross section perpendicular to the length direction X of the core wire 110) is at least partially arc-shaped. The groove can be an arc-shaped groove, such as a semicircular groove, or an elliptical arc-shaped groove; the groove can also be a U-shaped groove, etc.

[0095] The V-shaped groove refers to a groove structure in which the cross section of the groove (the cross section perpendicular to the length direction X of the core wire 110 ) is at least partially V-shaped, and the bottom of the groove may be set to be V-shaped.

[0096] The separation guide portion 126 is configured as an arc-shaped groove, a V-shaped groove or a U-shaped groove, which is convenient for processing and easy demolding if the injection molding process is adopted; at the same time, the groove structure of these shapes can form the weakest position at the bottom of the groove, so that the connecting section 122 can be separated along the bottom of the groove, thereby realizing the separation of the core wire 110, and further improving the operational accuracy of the separation of the core wire 110.

[0097] According to some embodiments of the present application, optionally, along the arrangement direction Y of two adjacent core wires 110 , the separation guide portion 126 is disposed in the middle of the connecting section 122 .

[0098] Among them, the arrangement direction Y of the two core wires 110 is also the arrangement direction of the two wrapping parts 121 connected by the connecting section 122. Along the arrangement direction (reference arrangement direction Y) of the corresponding two wrapping parts 121 (the corresponding two wrapping parts 121 refer to the two wrapping parts 121 located at the two ends of the connecting section 122 and connected by the connecting section 122), a separation guide part 126 is provided in the middle part of the connecting section 122.

[0099] The middle portion of the connecting section 122 refers to a region extending to both sides of a certain range from the center line of the connecting section 122 along the arrangement direction Y (the center first extends along the length direction X of the core wire 110). Exemplarily, the connecting section 122 can be roughly divided into three equal parts along the arrangement direction Y, wherein the middle portion can be the middle portion.

[0100] Exemplarily, the two corresponding wrapping portions 121 may be arranged approximately in mirror symmetry with respect to the center line of the connecting section 122 .

[0101] Optionally, the separation guide portion 126 may also be arranged in a substantially mirror-symmetrical manner with respect to the center line of the connecting section 122 .

[0102] By disposing the separation guide portion 126 in the middle of the connecting section 122 , the possibility of the wrapping portion 121 being damaged due to the separation position deviation, thereby affecting the performance of the cable structure 100 , can be reduced.

[0103] According to some embodiments of the present application, optionally, Figure 4 and Figure 5 As shown, the thickness of the connecting section 122 is reduced along the direction from the wrapping portion 121 to the middle of the connecting section 122. The wrapping portion 121 and the connecting section 122 are in a corresponding relationship of being connected to each other, that is, the wrapping portion 121 defined in this embodiment is the wrapping portion connected to the end of the connecting section 122.

[0104] That is, along the arrangement direction Y, the thickness of any one of the two ends of the connecting section 122 is greater than the thickness of the middle portion (the guide section 123). For example, the thickness of the connecting section 122 can be set to gradually decrease from any one end of the connecting section 122 to the separation guide portion 126 (the guide section 123). Figure 4 and Figure 5 As shown, along the arrangement direction Y, the thickness of the first side segment 124 gradually decreases from one end away from the separation guide portion 126 to one end close to the separation guide portion 126; the thickness of the second side segment 125 gradually decreases from one end away from the separation guide portion 126 to one end close to the separation guide portion 126. Among them, the first side segment 124 can be a side surface along the first direction Z (for example, the first sub-surface 1241) gradually approaching toward the other side (for example, the second sub-surface 1242) to reduce the thickness, or the two surfaces of the first side segment 124 oppositely arranged along the first direction Z (the first sub-surface 1241 and the first sub-surface 1241) are respectively approaching each other to reduce the thickness; similarly, the second side segment 125 can be a side surface along the first direction Z (for example, the third sub-surface 1251) gradually approaching toward the other side (for example, the fourth sub-surface 1252) to reduce the thickness, or the two surfaces of the second side segment 125 oppositely arranged along the first direction Z (the third sub-surface 1251 and the fourth sub-surface 1252) are respectively approaching each other to reduce the thickness.

[0105] The connecting section 122 is configured to have a thickness that gradually decreases near the middle (i.e., near the separation guide portion 126, or near the guide section 123), which can maintain the connection strength of the connecting section 122 and allow the separation guide portion 126 to have a smaller thickness. At the same time, the farther the connecting section 122 is from the separation guide portion 126, the higher its strength is, which can further reduce the possibility of the separation position offset toward the wrapping portion 121, thereby causing the wrapping portion 121 to be damaged, thereby affecting the performance of the wiring structure 100.

[0106] According to some embodiments of the present application, optionally, Figure 4 and Figure 5As shown, the connecting section 122 has a first surface 127 and a second surface 128 which are arranged oppositely along the first direction Z. Along the direction from the wrapping portion 121 to the middle of the connecting section 122, the first surface 127 and the second surface 128 are respectively oriented toward each other and approach each other so that the thickness of the connecting section 122 is reduced. The first direction Z, the length direction X of the core wire 110, and the arrangement direction Y intersect each other.

[0107] The first surface 127 includes a first sub-surface 1241 of the first side segment 124 and a third sub-surface 1251 of the second side segment 125, and the second surface 128 includes a second sub-surface 1242 of the first side segment 124 and a third sub-surface 1251 of the second side segment 125, the first sub-surface 1241 gradually approaches the second sub-surface 1242, and the second sub-surface 1242 gradually approaches the first sub-surface 1241 to gradually reduce the thickness of the first side segment 124; the third sub-surface 1251 gradually approaches the fourth sub-surface 1252, and the fourth sub-surface 1252 gradually approaches the second sub-surface 1242 to gradually reduce the thickness of the second side segment 125. Among them, the first sub-surface 1241 can be an arc-shaped extension or an inclined surface extension, so that the first sub-surface 1241 gradually approaches the second sub-surface 1242; the second sub-surface 1242 can be an arc-shaped extension or an inclined surface extension, so that the second sub-surface 1242 gradually approaches the second sub-surface 1242; the third sub-surface 1251 can be an arc-shaped extension or an inclined surface extension, so that the third sub-surface 1251 gradually approaches the fourth sub-surface 1252; the fourth sub-surface 1252 can be an arc-shaped extension or an inclined surface extension, so that the fourth sub-surface 1252 gradually approaches the third sub-surface 1251.

[0108] Exemplarily, the first side segment 124 and the second side segment 125 may be arranged in mirror symmetry with respect to a center line of the connecting segment 122 (a center line along the arrangement direction Y, the center line extending along the length direction X of the core wire 110 ).

[0109] Optionally, the first sub-surface 1241 and the second sub-surface 1242 may be arranged in a mirror-symmetrical manner. Optionally, the third sub-surface 1251 and the fourth sub-surface 1252 may be arranged in a mirror-symmetrical manner.

[0110] The two opposite sides of the connecting section 122 are gradually tapered toward the middle (i.e., the separation guide portion 126), so that both sides of the connecting section 122 can be used as separation starting surfaces, which is easy to operate. While maintaining the connection strength of the connecting section 122, the corresponding area of ​​the connecting section 122 and the separation guide portion 126 (i.e., the guide section 123) has a smaller thickness, thereby reducing the difficulty of separation.

[0111] According to some embodiments of the present application, optionally, Figure 4 and Figure 5As shown, the connection section 122 is provided with separation guides 126 on both sides in the first direction Z, and the separation guides 126 on both sides are arranged opposite to each other along the first direction Z. The first direction Z, the length direction X of the core wire 110 and the arrangement direction Y of two adjacent core wires 110 intersect each other.

[0112] That is to say, a separation guide portion 126 can be provided on the first surface 127, and a separation guide portion 126 can also be provided on the second surface 128, and the separation guide portions 126 of the first surface 127 and the second surface 128 are aligned. When the core wire 110 is separated, the connecting section 122 will be separated from the connecting line between the separation guide portions 126 of the first surface 127 and the second surface 128.

[0113] Exemplarily, the first surface 127 and the second surface 128 may be aligned and provided with grooves, and the grooves of the two surfaces may be provided in a mirror-symmetrical manner.

[0114] By providing the separation guide 126 on both sides of the connecting section 122, both sides of the connecting section 122 can have a separation guide function, and the core wire 110 can be separated from any side of the connecting section 122, which is convenient for operation. In some implementations, for example, when the separation guide 126 is provided as a groove, the thickness of the corresponding area of ​​the connecting section 122 and the separation guide 126 (i.e., the guide section 123) can be further reduced, thereby reducing the difficulty of separation.

[0115] It should be noted that, in some other embodiments, the separation guide portion 126 may be provided only on one side of the connecting section 122 along the first direction Z.

[0116] According to some embodiments of the present application, optionally, Figure 4 and Figure 5 As shown, along the first direction Z, the two opposite sides of the wrapping portion 121 are both protruding relative to the connecting section 122, and the connecting section 122 has a first surface 127 and a second surface 128 that are oppositely arranged along the first direction Z, the first surface 127 is connected to the corresponding surface of the wrapping portion 121 in an arc-shaped smooth connection, and the second surface 128 is connected to the corresponding surface of the wrapping portion 121 in an arc-shaped smooth connection, and the arrangement direction Y of the wrapping portion 121 and the connecting section 122, the length direction X of the core wire 110, and the first direction Z intersect each other.

[0117] The first surface 127 and the outer surface of the corresponding wrapping portion 121 may be in a circular arc or an elliptical arc shape with a smooth transition. The second surface 128 and the outer surface of the corresponding wrapping portion 121 may be in a circular arc or an elliptical arc shape with a smooth transition.

[0118] Exemplarily, the cross-section of the wrapping portion 121 is substantially circular, the first surface 127 is tangent to the outer surface of the wrapping portion 121 and is connected in an arc-shaped transition, and the second surface 128 is tangent to the outer surface of the wrapping portion 121 and is connected in an arc-shaped transition.

[0119] The arc-shaped transition connection between the connecting section 122 and the wrapping portion 121 can improve the connection strength of the connecting section 122 and the wrapping portion 121, and facilitate demoulding when the injection molding process is adopted.

[0120] According to some embodiments of the present application, optionally, the connected layer 120 is configured as an insulating member.

[0121] The connected layer 120 includes a wrapping portion 121 and a connecting section 122 , and both the wrapping portion 121 and the connecting section 122 are configured as insulating parts.

[0122] The insulating part refers to a part made of insulating material, which has a relatively high resistivity under normal use conditions and can be considered as a non-conductive part. For example, the interconnecting layer 120 can be an insulating part made of plastic, rubber, resin, etc.

[0123] like Figure 3 , Figure 4 and Figure 5As shown, the embodiment of the present application provides a cable arrangement structure 100, including a conjoined layer 120 of an integral structure and a plurality of core wires 110 arranged at intervals. The conjoined layer 120 is an insulating member, and includes a connecting section 122 and a plurality of wrapping portions 121. The outer sides of the plurality of core wires 110 are all coated with the wrapping portions 121. The conjoined layer 120 is provided with a connecting section 122 between two adjacent wrapping portions 121, and a separation guide portion 126 is provided on the connecting section 122. The separation guide portion 126 extends along the length direction X of the core wire 110. The connecting section 122 includes a first side section 124, a guide section 123, and a second side section 125, which are sequentially arranged and connected as a whole. The first side section 124 is connected to one of the two adjacent wrapping portions 121, and the second side section 125 is connected to the other of the two adjacent wrapping portions 121. The first side segment 124 has a first sub-surface 1241 and a second sub-surface 1242 which are oppositely arranged along the first direction Z, and the second side segment 125 has a third sub-surface 1251 and a fourth sub-surface 1252 which are oppositely arranged along the first direction Z, the first sub-surface 1241 and the third sub-surface 1251 are located on the same side of the connecting segment 122, the fourth sub-surface 1252 and the third sub-surface 1251 are located on the same side of the connecting segment 122, and a guide segment 123 is formed in the middle of the connecting segment 122, and arc grooves are respectively and alignedly arranged on opposite sides of the guide segment 123 along the first direction Z, and the arc grooves form a separation guide portion 126. The thickness of the first side segment 124 and the thickness of the second side segment 125 along the first direction Z are both greater than the thickness of the guide segment 123, and the first sub-surface 1241 and the second sub-surface 1242 approach each other from the end away from the separation guide portion 126 to the end close to the separation guide portion 126, so that the thickness of the first side segment 124 gradually decreases, and the third sub-surface 1251 and the fourth sub-surface 1252 approach each other from the end away from the separation guide portion 126 to the end close to the separation guide portion 126, so that the thickness of the second side segment 125 gradually decreases. The two opposite surfaces of the wrapping portion 121 are both protruding relative to the connecting segment 122, and the connecting segment 122 has a first surface 127 and a second surface 128 oppositely arranged along the first direction Z, the first surface 127 is connected to the corresponding surface of the wrapping portion 121 in an arc-shaped smooth connection, and the second surface 128 is connected to the corresponding surface of the wrapping portion 121 in an arc-shaped smooth connection. The first direction Z, the length direction X of the core wire 110 , and the arrangement direction Y of two adjacent core wires 110 corresponding to the separated wire portion are perpendicular to each other.

[0124] Some embodiments of the present application further provide a battery device 10 , including the wiring structure 100 proposed in the present application or any embodiment of the present application.

[0125] Exemplarily, the cable arrangement structure 100 can be used to connect the busbar 12 of the battery cell 20 and the sampler 30 to assist in sampling the temperature or pressure of the battery cell 20. When the busbar 12 of the battery cell 20 and part of the core wire 110 of the cable arrangement structure 100 are offset in position, the end of the connecting segment 122 corresponding to the core wire 110 can be torn, so that the core wire 110 and the end of the wrapping layer wrapping the core wire 110 are released as a whole and can be offset, so that the core wire 110 can be effectively connected to the corresponding busbar 12.
