Description

Technical Field

[0001] This application relates to the field of wire harness technology, and more specifically, to a low-voltage wire harness cable sheath, a low-voltage wire harness, and a battery. Background Technology

[0002] Currently, the automotive industry often uses various types of tape to secure low-voltage wiring harnesses. This method leads to several problems when connecting the harness terminals to the connector: When a connector needs to connect a large number of harnesses, the tape-wrapped wires need to be arranged in a linear or matrix shape to fit into the connector, requiring some twisting. In reality, these crimped-terminal harnesses cannot be inserted into the connector in a parallel orientation; instead, they are inserted at various angles. This results in: terminals being stressed, causing the terminal latches to fail and preventing proper engagement with the connector housing; the harness being pulled by stress, leading to incomplete terminal insertion or loose pins, resulting in signal loss; the harness insulation being cut by the rear of the terminal or the connector housing, causing insulation and waterproofing failures; and thinner harnesses may even experience internal wire breakage due to excessive twisting. Utility Model Content

[0003] The main objective of this application is to provide a low-voltage wiring harness sheath, a low-voltage wiring harness, and a battery to solve the problem of easy failure in the connection between the low-voltage wiring harness terminals and connectors in the prior art.

[0004] To achieve the above objectives, according to one aspect of this application, a low-voltage wiring harness sheath is provided, comprising: a limiting portion separately disposed from a connector, the limiting portion having a plurality of cable positions arranged sequentially; a wrapping portion, the wrapping portion and the connector being located on opposite sides of the limiting portion, the wrapping portion having a wrapping area for wrapping the cable; the cable being connected to the connector from the wrapping area via the cable positions.

[0005] Furthermore, the packaged area also has a first side for connecting with the limiting portion and a second side opposite to the first side, wherein the opening size of the first side is larger than the opening size of the second side.

[0006] Furthermore, the opening size of the wrapping area gradually decreases in the direction away from the limiting part.

[0007] Furthermore, the wrapping section has a threading groove that extends through both sides of the wrapping section along the axial direction of the cable.

[0008] Furthermore, the wire channel includes at least one of the following: straight type, zigzag type, and arc type.

[0009] Furthermore, the wrapping section also has a clearance groove that extends circumferentially along the wrapping section.

[0010] Furthermore, there are multiple clearance slots, which are arranged at intervals along the axial direction of the cable.

[0011] Furthermore, at least part of the two adjacent and spaced-apart clearance slots are staggered.

[0012] Furthermore, the threading groove and the clearance groove are located on opposite sides of the wrapping section.

[0013] Furthermore, the limiting part and / or the wrapping part are flexible parts.

[0014] Furthermore, the limiting part has multiple snap-fit ​​holes arranged in a straight line, which serve as cable positions.

[0015] Furthermore, along the axial direction of the cable, the length a of the limiting part is ≥ 2mm; the cross-sectional area S of the wrapping part ranges from [Smin, Smax], where Smin = π(rmin). 2 y, Smax = π(rmax) 2 The diameter D of the packaged part ranges from [Dmin, Dmax], where Dmin = 2(Smin / π). 1 / 2 Dmax = 2(Smax / π) 1 / 2 Where rmin and rmax are the minimum and maximum outer radii of a single cable, respectively, and y is the number of strands in the cable.

[0016] According to another aspect of this application, a low-voltage wiring harness is provided, including a cable, a connector, and the aforementioned low-voltage wiring harness cable sheath. The connector is connected to the end of the cable, the low-voltage wiring harness cable sheath is sleeved on the outside of the cable, and the connector and the low-voltage wiring harness cable sheath are separately disposed.

[0017] According to another aspect of this application, a battery is provided, including a cell and the aforementioned low-voltage wiring harness, wherein the low-voltage wiring harness is connected to the cell.

[0018] By applying the technical solution of this application, the arrangement of the low-voltage wire harness and connector at the insertion point is achieved by setting a wrapping area and multiple cable positions. On the one hand, the cables can be aligned with different positions on the connector through multiple cable positions, so that the cable terminals can be inserted into the connector at the angle defined by the cable positions, thereby reducing the stress on the cable ends and preventing connection failure between the cable terminals and the connector when the cables are inserted, pulled out, or twisted. On the other hand, the wrapping part organizes the cables, gathering multiple cables into the wrapping area, thereby avoiding the problems of messy, twisted, and bent cables at the insertion point when there are many cables. Moreover, when a single cable is subjected to external force, the traditional connection method may cause the corresponding terminal of the cable to be pulled out. The low-voltage wire harness cable sheath of this embodiment can transmit the force to all cables, so that all cables are evenly distributed with the external force, preventing a single cable from being pulled out. In addition, the separate setting of the connector and the low-voltage wire harness cable sheath allows them to be manufactured and processed separately, and different materials can be used to meet their respective characteristics, so that their respective functions do not affect each other.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0034] In this application, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this application.

[0035] It should be noted that "multiple" in the above embodiments refers to at least two.

[0036] To address the problem of easy failure in the connection between low-voltage wiring harness terminals and connectors in the prior art, this application provides a low-voltage wiring harness cable sheath, a low-voltage wiring harness, and a battery.

[0037] like Figures 1 to 6 The low-voltage cable harness sheath shown includes a limiting part 10 and a wrapping part 20 separately disposed from the connector 40. The limiting part 10 has a plurality of cable positions 11 arranged in sequence. The wrapping part 20 and the connector 40 are respectively located on both sides of the limiting part 10. The wrapping part 20 has a wrapping area for wrapping the cable 30. The cable 30 is connected to the connector 40 from the wrapping area via the cable positions 11.

[0038] This embodiment achieves the arrangement and organization of the low-voltage wire harness at the connector 40 insertion point by setting up a wrapping area and multiple cable positions 11. On the one hand, this allows the cable 30 to be aligned with different positions on the connector 40 through the multiple cable positions 11, thereby ensuring that the cable 30 terminals are inserted into the connector 40 at the angle defined by the cable positions 11. This reduces the stress on the cable 30 ends and prevents connection failure between the cable 30 terminals and the connector 40 when inserting, removing, or twisting the cable 30. On the other hand, the wrapping part 20 organizes the cables 30, gathering multiple cables 30 into the wrapping area. Within the area, this avoids the problem of messy, twisted, and bent cables 30 at the plug position when there are many cables 30. Moreover, when a single cable 30 is subjected to external force, the traditional connection method may cause the terminal corresponding to the cable 30 to be pulled out. The low-voltage cable harness sheath of this embodiment can transmit the force to all cables 30 so that all cables 30 are evenly distributed with the external force, preventing a single cable 30 from being pulled out. In addition, the separate setting of the connector 40 and the low-voltage cable harness sheath allows them to be manufactured and processed separately, and different materials can be used to meet their respective characteristics, so that their respective functions do not affect each other.

[0039] In this embodiment, the wrapping part 20 is connected to the limiting part 10, so that the low-voltage wire harness cable sheath forms an integral component. Of course, the wrapping part 20 and the limiting part 10 can also be set separately.

[0040] In this embodiment, the wrapping area also has a first side for connecting with the limiting part 10 and a second side opposite to the first side. The opening size of the first side is larger than the opening size of the second side, so that the cable 30 extends from the second side to the first side and enters the limiting part 10, and extends from the cable position 11 to connect with the connector 40. Specifically, the second side of the limiting part 10 gathers the cable 30 into the wrapping area and positions the cable 30 to prevent it from moving. The opening of the first side is larger than that of the second side, so that the gathered cable 30 is dispersed to facilitate its mating with the side-by-side cable positions 11, reducing the stress on the cable 30 when mating with the cable position 11.

[0041] In this embodiment, the opening size of the wrapping area gradually decreases along the direction away from the limiting part 10, thereby fixing the cable 30 while reducing the stress on the connection between the cable 30 and the cable position 11. Figure 4 , Figure 5As shown, in this embodiment, the cross-sectional size and shape of the wrapping area perpendicular to the extension direction of the cable 30 are not constant; they gradually change from a circular cross-section to a flat cross-section. The cable 30, passing through it, is arranged in a circular pattern on the second side, and becomes linear or matrix-shaped when extending to the first side. The wrapping area protects the cable 30 from this transitional twisting state. The opening on the second side is circular to facilitate the gathering and fixing of the cable 30, while the opening on the first side is flat to facilitate connection and cooperation with the multiple cable positions 11 of the limiting part 10. Of course, the shape of the opening on the first side can be adjusted according to the arrangement of the cable positions 11. Depending on actual needs, the second side area can be wrapped with tape to axially position the cable 30 and further fix its position.

[0042] like Figure 1 , Figure 2 As shown, in this embodiment, the wrapping part 20 has a wire-passing groove 21. Along the axial direction of the cable 30, the wire-passing groove 21 passes through both sides of the wrapping part 20. The two ends of the wire-passing groove 21 are located on the first side and the second side of the wrapping area, respectively. In this way, the wire-passing groove 21 is used to guide the cable 30 that has been crimped through the terminal smoothly through. On the other hand, it makes the wrapping part 20 have a certain degree of elasticity, so that the size of the wrapping area can be adjusted. This allows the number and specifications of the cables 30 that can be wrapped in the wrapping area to be adjusted appropriately, thereby expanding the application range of the low-voltage wire harness sheath. Moreover, it can effectively reduce the friction of the wire harness inside the wrapping part 20 and protect the cable 30 from damage. It is suitable for occasions where the cable 30 needs to be moved frequently, such as the connection of stage lighting equipment, to ensure the safety and stability of the wire harness during the movement process.

[0043] In this embodiment, the threading groove 21 includes at least one of straight, zigzag, and arc types. For example... Figure 2As shown, the cable tray 21 in this embodiment is designed as an arc shape, consisting of multiple arc segments extending in different directions. The intersections of the arcs have no sharp corners, ensuring strength at the intersections and reducing stress concentration. Thus, on one hand, the arc-shaped cable tray 21 guides the crimped-terminal cables 30 to successively pass through the cable tray 21 into the enclosure area. On the other hand, the cables 30 located in the cable tray 21 are exposed. The arc shape allows the cable tray 21 to contact multiple cables 30, preventing the cable tray 21 from extending along the same cable 30. This effectively prevents the cable from detaching from the enclosure 20, improving the reliability of the low-voltage cable harness sheath and facilitating the operator to remove the cable 30 from the enclosure area. A zigzag shape also has the advantages of an arc shape. Optionally, the cable tray 21 can also be designed as a zigzag shape, or a combination of arc and zigzag shapes. Of course, the cable tray 21 can also be set as a combination of straight and curved shapes, or a combination of straight and curved shapes, so as to guide the cable 30 to pass through smoothly and prevent the cable 30 from coming out of the wrapping part 20. For example, the two ends of the cable tray 21 can be set as curved, and the middle part of the cable tray 21 can be set as straight.

[0044] like Figure 3 As shown, in this embodiment, the wrapping part 20 also has a relief groove 22, which extends circumferentially along the wrapping part 20, thereby giving the wrapping part 20 a certain degree of flexibility. This allows the wrapping part 20 and the cable 30 to bend within a certain range, giving the cable 30 a certain range of movement and improving the flexibility of the low-voltage cable harness sheath. In this embodiment, the relief groove 22 is a rectangular groove to ensure the strength of the wrapping part 20 while improving its flexibility. Moreover, the relief groove 22 penetrates the surface of the wrapping part 20, which not only improves the flexibility of the wrapping part 20, but also allows the cable 30 within the wrapping area to be observed through the relief groove 22. Optionally, rounded corners are provided at the four corners of the rectangle to reduce stress concentration. Of course, the depth and width of the relief groove 22 can be adjusted according to actual needs. A moderate depth and width can ensure the free movement of the cable harness inside the sheath while maintaining the structural strength of the sheath. In scenarios where the cable 30 needs to have a certain degree of bending, such as the wiring layout inside an aircraft, the design of the relief groove 22 can meet the bending requirements of the cable harness while ensuring the safety and stability of the wiring. The shape of the clearance groove 22 is not limited to this; it can also be set to other shapes as long as it can improve the flexibility of the wrapping part 20 and meet the usage requirements of the cable 30.

[0045] Considering that the main function of the clearance groove 22 is to improve the flexibility of the wrapping part 20, it should not be set too wide. In this embodiment, multiple clearance grooves 22 are provided, and each clearance groove 22 is arranged at intervals along the axial direction of the cable 30. In this way, the clearance grooves 22 can be distributed on the surface of the wrapping part 20, thereby improving the flexibility of the wrapping part 20 at all points, without occupying too much area of ​​the wrapping part 20 and affecting its strength. The lengths of each clearance groove 22 along the circumference of the wrapping part 20 can be the same or different, depending on actual needs. Of course, the clearance grooves 22 do not have to be arranged completely along the axial direction of the cable 30. For example, mutually intersecting clearance grooves 22 can be provided, that is, the clearance grooves 22 can have a certain angle between them, which can meet the requirements of improving the flexibility of the wrapping part 20, allowing the cable 30 to bend within a certain range, satisfying the limited insertion space of the cable 30, and allowing the cable 30 to deform under stress.

[0046] In this embodiment, at least part of the two adjacent, spaced-apart clearance slots 22 are staggered. This avoids situations where the strength or flexibility of the wrapping portion 20 is excessively high or low in certain areas, thereby improving the uniformity of strength and flexibility throughout the wrapping portion 20. This results in good flexibility of the wrapping portion 20 in multiple directions, allowing the cable 30 to deform under stress within a certain range. This prevents uneven distribution of strength and flexibility in the wrapping portion 20 from limiting the range of motion of the cable 30 and affecting the service life of the cable 30 and the low-voltage wiring harness sheath. Consequently, the low-voltage wiring harness sheath can be adapted to various complex working environments. For example, in the wiring layout inside a robot, this design can adapt to the multi-directional movement of the robot joints, ensuring smooth and safe wiring.

[0047] In this embodiment, the threading groove 21 and the clearance groove 22 are located on opposite side surfaces of the wrapping portion 20, thereby enabling the wrapping portion 20 to simultaneously allow the cable 30 to pass smoothly and bend smoothly without interference. Figure 1 As shown, in this embodiment, the cable guide 21 and the cable position 11 are located on the same side of the low-voltage cable harness sheath, allowing the operator to insert the cable 30 into the wrapping area and fix it in the cable position 11 from the same side of the low-voltage cable harness sheath. The cable guide 21 and the clearance groove 22, located on different sides of the wrapping portion 20, both contribute to improving the flexibility of the wrapping portion 20.

[0048] like Figure 2 , Figure 3 , Figure 6As shown, in this embodiment, the limiting part 10 and the wrapping part 20 are flexible parts. The flexibility of the limiting part 10 allows the cable 30 to shift to a certain extent, enabling it to smoothly connect with the connector 40 even when the connector 40 is slightly deformed. The flexibility of the wrapping part 20 allows it to gather cables 30 from multiple directions and makes it easier for the limiting part 10 to mate with the connector 40. Optionally, the limiting part 10 and the wrapping part 20 are integrally molded and can be processed by injection molding, dip molding, or other methods. Flexible plastic materials such as soft PVC (polyvinyl chloride) or TPE (thermoplastic elastomer) can be used, giving them both strength and flexibility. The flexible part can also reduce damage to the cable 30 caused by friction and pulling, extending the service life of the cable 30. Of course, depending on actual needs, only the limiting part 10 or only the wrapping part 20 can be provided as flexible parts, as long as it facilitates the mating of the cable 30 and the connector 40.

[0049] like Figure 4 As shown, in this embodiment, the limiting part 10 has multiple snap-fit ​​holes arranged in a straight line. These snap-fit ​​holes serve as cable positions 11, primarily used to snap and fix the cable 30 in a linear or matrix arrangement. In this embodiment, the snap-fit ​​hole cross-section is set in a D-shape, meaning that an opening is provided on the circumferential side of the circular hole to facilitate the cable 30 entering the snap-fit ​​hole. This cross-sectional shape of the snap-fit ​​hole matches the circular cross-section of the cable 30, thus both fixing the cable 30 and protecting it from damage. Preferably, the diameter of the snap-fit ​​hole is smaller than the diameter of the cable 30 cross-section, meaning there is a certain interference fit between the snap-fit ​​hole and the cable 30. The slot size of the snap-fit ​​hole is smaller than the diameter of the cable 30. This makes the fixation of the cable 30 more secure, preventing the cable 30 from easily flying out and making the connection between the cable 30 and the connector 40 more reliable. The end of the snap-fit ​​hole near the wrapping part 20 is preferably provided with an angle to facilitate the cable 30 passing through and being fixed into the snap-fit ​​hole from both sides, reducing stress concentration.

[0050] In this embodiment, the snap-fit ​​holes are arranged in a parallel row along the extension direction of the cable 30, thereby ensuring that the cables 30 are parallel to each other after extending from the cable position 11, so as to match the socket structure of the connector 40 and reduce the stress generated by the insertion of the cable 30. The connector 40 has various structural forms. Depending on the actual situation, the cable position 11 can also be set with multiple rows of snap-fit ​​holes to match connectors 40 with different numbers of sockets.

[0051] It should be noted that in this embodiment, the cable position 11, the wire threading groove 21, the clearance groove 22, and the snap-fit ​​hole are all provided with preferred dimensions. The length of the limiting part 10, that is, the length of the snap-fit ​​hole a, is ≥ 2mm to ensure the effectiveness of the snap-fit; the diameter of the hole at the guide angle at the end of the snap-fit ​​hole near the wrapping part 20 is set to the diameter of the cable 30 to facilitate the passage of the cable 30; the width dimension v of the wire threading groove 21 is equal to the diameter of the wire harness. Since the wire threading groove 21 is set as an arc or a zigzag shape, the width of the entire wire threading groove 21 along the circumference of the wrapping part 20 is larger than the width of the wire threading groove 21 itself, preferably set to 1.5 times the diameter of the cable 30; the diameter d of the snap-fit ​​hole is determined by different types of low-voltage wire harnesses. Taking this embodiment as an example, this embodiment uses a cable with an outer diameter of 1.3mm, so the diameter of the snap-fit ​​hole is set to 1. The tolerance is -0.2. Dimension c is the center distance between adjacent snap-fit ​​holes. This dimension is critical, determining whether multiple cables 30 can be inserted parallel to each other into the connector 40. The recommended tolerance is ±0.1. The nominal size is determined by the center-to-center spacing of the pin chambers of the specific connector 40. For a 12V connector 40, the common center-to-center spacing is 2mm, which can be used as a reference. The cross-sectional area S of the second side of the wrapping area must be able to exactly include multiple cables 30. The value range of S is [Smin, Smax]. The value range of the diameter D of the second side of the wrapping area is [Dmin, Dmax], where Smin = π(rmin). 2 y, Smax = π(rmax) 2 y, Dmin = 2(Smin / π) 1 / 2 Dmax = 2(Smax / π) 1 / 2 rmin and rmax are the minimum and maximum outer radii of a single cable 30, respectively, which can be obtained by referring to the standard specification table of different cable harnesses. y is the number of strands in cable 30. The wrapping part 20 requires uniform thickness throughout. e is the wall thickness of the wrapping part 20. The recommended wall thickness range is 0.7-1.5 mm, depending on the actual situation. The recommended width of the clearance groove 22 is 1 mm. The spacing between the axially arranged clearance grooves 22 is 1.2-1.5 times its width. Depending on the actual situation, if the overall size of the wrapping part 20 is small, the clearance groove 22 can be omitted.

[0052] like Figure 9 , Figure 10As shown, this application also provides a low-voltage wire harness, including a cable 30, a connector 40, and the aforementioned low-voltage wire harness cable sheath. The connector 40 is connected to the end of the cable 30. The low-voltage wire harness cable sheath is sleeved on the outside of the cable 30. The connector 40 and the low-voltage wire harness cable sheath are separately arranged. In this way, the cable 30 is fixed in the wrapping area of ​​the low-voltage wire harness cable sheath and in the cable position 11, thereby ensuring that the cables 30 are parallel to each other before insertion. The end of the cable 30 extends from the cable position 11 and can be smoothly inserted into the connector 40 without generating stress after insertion, thus avoiding the stress caused by various insertion angles of the cable 30 when the cable 30 wrapped with traditional tape is inserted into the connector 40. Figure 7 , Figure 8 As shown, the connector 40 in this embodiment has a straight-line arrangement of its ports, and therefore the multiple cable positions 11 are also arranged in a straight line. Consequently, the multiple cables 30 are also arranged in a straight line within the limiting part 10, making the arrangement of the cables 30 correspond to the arrangement of the connector 40, thereby reducing the stress on the connection between the cables 30 and the connector 40. Of course, the multiple ports of the connector 40 can also be arranged in multiple rows, i.e., in a matrix shape, and the multiple cable positions 11 are also arranged in a matrix shape. Thus, the cables 30 are fixed in the cable positions 11 in a matrix shape, which also reduces the stress when the cables 30 are plugged into the connector 40.

[0053] This application also provides a battery, including a battery cell and the aforementioned low-voltage wiring harness. The low-voltage wiring harness is connected to the battery cell. The arrangement of the low-voltage wiring harness in this embodiment is beneficial to improving the reliability of the connection between the low-voltage wiring harness and the battery cell, thereby improving the reliability of the battery. Moreover, it avoids the situation where the cables 30 are messy, twisted, or bent at the plug-in position when there are too many cables 30. It fills the gap in the arrangement of low-voltage wiring harness plug-in, making the arrangement of cables 30 more beautiful and concise.

[0054] It should be noted that "multiple" in the above embodiments refers to at least two.

[0055] As can be seen from the above description, the embodiments of this application achieve the following technical effects:

[0056] 1. This solves the problem of easy failure in the connection between low-voltage wire harness terminals and connectors in existing technologies;

[0057] 2. By setting up a wrapping area and multiple cable positions, the arrangement and organization of low-voltage wire harnesses at connector insertion points can be achieved;

[0058] 3. This allows the cable to be positioned at different locations on the connector via multiple cable positions, enabling the cable terminals to be inserted into the connector at the angle defined by the cable positions. This reduces the stress on the cable ends and prevents connection failure between the cable terminals and the connector when inserting, unplugging, or twisting the cable.

[0059] 4. The cable management section organizes the cables, grouping multiple cables together within the packaging area to avoid the problem of messy, twisted, or bent cables at the plug points when there are many cables.

[0060] 5. When a single cable is subjected to external force, the traditional connection method may cause the corresponding terminal of the cable to be pulled out. The low-voltage cable harness sheath can transmit the force to all cables so that the external force is evenly distributed among all cables, thus preventing a single cable from being pulled out.
