[0046] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0047] Example 1

[0048] The embodiment of the present utility model discloses a wiring harness fuse 10, such as Figure 1As shown, the wiring harness fuse 10 includes a housing 11, a fuse 15 disposed in the housing 11, a fixing assembly 12, two terminals 13, and two clamps 14. The housing 11 includes a tube 111 and a cover 112 disposed at least at one end of the tube 111, and the tube 111 and the cover 112 are detachably connected. The fixing assembly 12 is disposed in the tube 111, and the fixing assembly 12 includes a support 121, two clamps 14 are disposed on the support 121, and are located in the tube 111, and the two ends of the fuse 15 are respectively clamped with the two clamps 14. The two terminals 13 are respectively disposed at the two ends of the support 121 and are located in the tube 111, each terminal 13 is electrically connected to a corresponding clamp 14, and each terminal 13 is used to connect to the end of the wiring harness passing through the corresponding end of the housing 11.

[0049] It should be noted that the housing 11 should be made of an insulating material, such as plastic, glass, or ceramic. The housing 11 includes a tube 111 and a cover 112 disposed at at least one end of the tube 111. The cross-section of the cover 112 should be compatible with the cross-section of the tube 111. The cross-section of the tube 111 can be circular, square, or other shapes, as long as it can accommodate the fixing assembly 12, the two terminals 13, and the two clamps 14 inside the tube 111. The corresponding cross-section of the cover 112 is also circular, square, or other compatible shapes. Furthermore, the tube 111 can be integrally formed or comprised of two symmetrically divided upper and lower shells, the upper and lower shells being combined into a circular, square, or other shape. Those skilled in the art can configure it as needed. It should be noted that the housing 11 includes a tube 111 and a cover 112 provided at least at one end of the tube 111, and the tube 111 and the cover 112 together form a substantially closed cavity (the tube and the cover need to have a hole for the wiring harness to pass through), for arranging the fuse 15; specifically, the cover 112 may be provided at one end of the tube 111 and detachably connected to the tube 111, and a bottom plate may be provided at the other end of the tube 111, the bottom plate being fixedly connected to the tube 111, and the wiring harness may pass through the bottom plate; or Figure 1 As shown, both ends of the tube body 111 are provided with a cover body 112 that is detachably connected to the tube body 111; regardless of the setting method, since the wiring harness needs to pass through the shell 11, the inside of the shell 11 is an electrically powered working environment, and the shell 11 must provide a relatively closed space for the internal components. In order to prevent the wiring harness from leaving a large gap after passing through the shell 11, the holes in the cover body 112 and the bottom plate for passing the wiring harness should be set to a circular shape that is adapted to the cross-section of the wiring harness.

[0050] The tube body 111 and the cover body 112 are detachably connected. Specifically, the cross-sections of the cover body 112 and the tube body 111 are circular, and the detachable connection can be achieved by screwing; the tube body 111 and the cover body 112 can also be detachably connected by snapping together with a matching snap-fit ​​structure, wherein the snap-fit ​​structure can be an elastic snap-fit ​​with a protrusion provided on the outer wall of the tube body 111, and a card extending along the direction of the tube body 111 is provided on the outer wall of the cover body 112. The elastic snap-fit ​​and the card are connected or detached by applying pressure; when the tube body 111 and the cover body 112 are When snapping in, an elastic component such as a rubber ring can also be installed at the joint of the tube body 111 and the cover body 112 to achieve the connection between the tube body 111 and the cover body 112. Since the elastic component is elastic, it is also convenient to disassemble the cover body 112 and the shell; a slideway and a positioning groove can also be provided on the inner wall of the cover body 112, and a matching positioning piece can be provided on the outer wall of the tube body 111. After the tube body 111 and the cover body 112 are matched and connected, the positioning piece can be rotated along the slide groove by a certain angle so that the positioning piece and the positioning groove are matched for fixed connection. When disassembling, just rotate in the opposite direction.

[0051] Furthermore, the fixing assembly 12 is disposed in the tube body 111. The fixing assembly 12 can be detachably connected to the shell 11, for example, the fixing assembly 12 is screwed or clamped to the cover body 112. After the tube body 111 and the shell 11 are detached, the tube body 111 can be moved relative to the support body 121. The fixing assembly 12 includes a support body 121, which is used to support the fuse 15. The support body 121 can be configured as a box-shaped body or a tubular body with an opening (the opening is configured according to the specifications of the fuse 15 and needs to be able to replace the fuse 15). The fuse 15 is placed inside the support body 121; the support body 121 can also be a square, arc-shaped or other shaped sheet. The fuse 15 is placed above the support body 121, such as Figure 2 As shown, an example is shown in which the support body 121 is a square sheet.

[0052] Furthermore, two clamping members 14 are provided on the support body 121 for clamping the fuse 15. Specifically, the two clamping members 14 can be respectively provided at both ends of the length direction of the support body 121 (the direction is parallel to the extension direction of the tube body), and the distance between the two clamping members 14 is determined according to the length of the fuse 15. The clamping members 14 are fixedly connected to the support body 121. To facilitate the replacement of the fuse 15 on the support body 121, the two ends of the fuse 15 are respectively engaged with the two clamping members 14. Specifically, as Figure 1As shown, each clamping member 14 can specifically be two card claws arranged opposite to each other in the width direction of the support body 121, and the fuse 15 is clamped in the two claws; the clamping member 14 can also be a baffle arranged along the width direction of the support body 121 and a conductive spring on the inner side of the baffle (the inner side refers to the side close to the fuse 15) and fixedly connected to the baffle, and the fuse 15 is placed in front of the baffles on both sides and abuts against the conductive spring; the clamping member 14 can also be set as an annular body with a buckle arranged along the circumference of the outer wall of the fuse 15. When the buckle is opened, the replacement fuse can be placed, and when the buckle is buckled, the fuse 15 is set between the clamping members 14.

[0053] The wiring harness fuse 10 is fixedly connected to the wiring harness (specifically, the electrical harness) through one end of the two terminals 13, which can be crimped or soldered. The other end of the two terminals 13 away from the wiring harness is electrically connected to the corresponding clamping parts 14. Specifically, the terminals 13 and the corresponding clamping parts 14 can be integrally formed, or the terminals 13 and the corresponding clamping parts 14 can be welded, or wires can be connected to the opposite ends of the terminals 13 and the corresponding clamping parts 14 respectively, and the wires connecting the terminals 13 and the clamping parts 14 are connected to each other to achieve electrical connection between the terminals 13 and the clamping parts 14.

[0054] The wiring harness fuse 10 provided by the present invention can be widely used in various devices and power systems to ensure the normal operation of the power system. For example, it can be used to protect automobile circuits, specifically the engine, lights and audio in the car, which all require power supply. It can also be used in household circuits to protect household circuits and electrical appliances.

[0055] When the current passing through the wiring harness exceeds the specified limit, the heat of the current itself causes the fuse 15 in the clamp 14 to melt. When the fuse 15 needs to be replaced, the shell 11 is first disassembled, the tube 111 and the cover 112 are disassembled, and the tube 111 is moved along the wiring harness to expose the fixing component 12. The fuse 15 is taken out of the clamp 14 and replaced with a new fuse 15. Then the tube 111 is moved and connected to the cover 112 to complete the replacement.

[0056] By adopting the above technical solution, the wiring harness fuse 10 includes a shell 11, which includes a detachably connected tube body 111 and a cover body 112. The support portion is arranged in the shell 11, and the fuse 15 is clamped to the support body 121 through two clamping members 14. The two terminals 13 connect the wiring harness and the clamping members 14. Its structure and assembly are simple; and when a circuit breaker occurs, the tube body 111 and the cover body 112 of the wiring harness fuse 10 can be disassembled and moved first, and then the fuse 15 clamped on the support body 121 can be quickly replaced, thereby solving the problem of difficulty in repairing and replacing the fuse 15 and the high time cost.

[0057] According to a specific implementation of the present invention, Figure 1 and Figure 5 As shown, the housing 11 includes two covers 112 respectively disposed at both ends of the tube 111 .

[0058] By adopting the above technical solution, two covers 112 are respectively provided at both ends of the tube body 111. When replacing the fuse 15 in the wiring harness fuse 10, compared with the method in which the cover 112 is only provided at one end of the tube body 111 and can only be moved along the side of the tube body 111 away from the cover 112 during disassembly, the covers 112 at both ends are removed and separated from the tube body 111 at the same time, and then the tube body 111 can be moved along both sides of the cover 112, thereby improving the applicability of the movement of the tube body 111 and thus improving the user experience.

[0059] According to a specific embodiment of the present invention, the fixing assembly 12 also includes two connecting members 122 respectively arranged at both ends of the support body 121, one end of each connecting member 122 is fixedly connected to the corresponding end of the support body 121, and the other end of each connecting member 122 is used for detachable connection with the inner wall of the corresponding end of the shell 11.

[0060] It should be noted that, when the shell 11 is square or other shapes, the detachable connection between the connecting piece 122 and the inner wall of the shell 11 can be a snap connection. For example, a positioning piece extending in the direction of the cover body 112 is provided on the outer wall of the connecting piece 122, one end of the positioning piece is fixedly connected to the outer wall of the connecting piece 122, and the other end is a free end. A locking piece adapted to the positioning piece is provided on the inner wall of the shell 11, and the locking piece is at the free end of the positioning piece. When the shell 11 is replaced and disassembled, the shell 11 can be moved in the direction of the free end, and the positioning piece is separated from the locking piece. When the shell 11 is round, such as Figure 1 As shown, the detachable connection between the connecting member 122 and the inner wall of the housing 11 can be a threaded connection.

[0061] Using the above technical solution, two connecting pieces 122 are provided at both ends of the support body 121. Through the detachable connection between the connecting pieces 122 and the inner wall of the shell 11, when the fuse 15 does not need to be replaced, the support body 121 is fixedly connected to the shell 11 through the connecting pieces 122, providing a stable working environment for the fuse 15. When the fuse 15 needs to be replaced, the support body 121 can be removed from the shell 11 through the connecting pieces 122, providing space for replacing the fuse 15.

[0062] According to a specific implementation of the present invention, Figure 1 and Figure 2 As shown, the tube body 111 and each cover body 112 are cylindrical; Figure 3 As shown, the inner wall of each cover 112 near the end of the fuse 15 is provided with an internal thread 1122 along the circumferential direction, and a slot 1121 extending along the circumferential direction is provided between the inner wall and the outer wall of the cover 112; Figure 1 and Figure 2 Each connecting piece 122 shown is a flange, and an external thread 1221 is provided on the outer periphery of the flange. The cover body 112 is connected to the corresponding flange through the external thread 1221 and the internal thread 1122; and the hole in the center of each flange is used to pass the corresponding wiring harness; the two ends of the tube body 111 are respectively clamped in the slot 1121 of each cover body 112.

[0063] Specifically, the internal thread 1122 and the external thread 1221 can be adapted, and the number of turns and the pitch can be set according to needs; Figure 4 As shown, the width of the slot 1121 needs to be larger than the thickness of the tube body 111 to facilitate the insertion of the tube body 111, and the width of the slot 1121 should be slightly larger than the thickness of the tube body 111 to prevent the tube body 111 from having too much movable space in the slot 1121, resulting in unstable installation. The thickness of the tube body 111 can be set to 1.5-2.5mm, for example, the corresponding setting of the slot 1121 width is 2-3mm.

[0064] By adopting the above technical solution, a circumferentially extending slot 1121 is provided between the inner and outer walls of the cover body 112, and the two ends of the tube body 111 are respectively clamped between the slots 1121 of the two cover bodies 112. The tube body 111 only needs to be inserted into the slot 1121, and the structure is simple; further, the cover body 112 with an internal thread 1122 and the flange with an external thread 1221 can realize a detachable connection between the connector 122 and the shell 11, and when the cover body 112 is connected to the flange, the tube body 111 clamped in the slot 1121 can also be further fixed. When assembling or disassembling the wiring harness fuse 10, it is only necessary to tighten or unscrew the fit. The assembly process is simple, and maintenance and replacement can also be carried out quickly, saving time and cost.

[0065] According to a specific implementation of the present invention, each terminal 13 and each flange is fixedly connected to the support body 121 by welding.

[0066] By adopting the above technical solution, the fixed connection strength between the terminal 13 and the support body 121 and between the flange and the support body 121 can be enhanced.

[0067] According to a specific embodiment of the present invention, each clamping member 14 includes a reed claw 141 , and the reed claw 141 and the corresponding terminal 13 are configured as an integrated structure.

[0068] Specifically, if Figure 1 、 Figure 7 and Figure 8As shown, the reed claw 141 includes two claws arranged opposite to each other on both sides of the corresponding terminal 13 and a connecting piece arranged between the two claws. The connecting piece is electrically connected to the corresponding terminal 13. The bottom to the middle of each claw is an arc-shaped piece that is adapted to the shape of the fuse 15 to better accommodate the fuse 15. The upper part of the claw is a parallel rectangle, and the maximum distance between the middle parts of the two claws is greater than the maximum distance at the top, which can limit the fuse 15 and prevent the fuse 15 from falling from the reed claw 141. The reed claw 141 and the terminal 13 are arranged as an integrated structure, which improves the stability of the connection between the reed claw 141 and the terminal 13.

[0069] According to a specific implementation of the present invention, Figure 1 As shown, the wiring harness fuse 10 further includes two sealing rings 16 , the outer wall of each sealing ring 16 being threadedly connected to the inner wall of a hole at one end of the housing 11 for passing the wiring harness, and the inner wall of each sealing ring 16 being used to be sleeved on the outer periphery of the corresponding wiring harness.

[0070] By adopting the above technical solution, two sealing rings 16 are sleeved on the outer periphery of the wiring harness, and the sealing rings 16 are threadedly connected to the holes at both ends of the shell 11 for passing the wiring harness, so that the internal space of the tube body 111 can be sealed to prevent the internal arc from flying out to injure the human body or cause a fire, and can also effectively prevent external dust and other influencing objects from entering the tube body 111 and affecting the operation of the fuse.

[0071] According to a specific implementation of the present invention, Figure 5 As shown, the tube body 111 is made of transparent material.

[0072] By adopting the above technical solution, the transparent tube 111 ( Figure 5 The dotted line part) can be used to check whether the internal fuse 15 is disconnected without disassembling the tube body 111, thereby improving the user experience. Figure 6 As shown, the tube body 111 is set to be an opaque material, and those skilled in the art can set it according to needs.

[0073] Next, refer to Figure 1The assembly and disassembly sequences of the wiring harness fuse 10 are described as follows: when assembling the wiring harness fuse 10, one end of the wiring harness at both ends passes through the corresponding sealing ring 16, cover 112, tube 111 and flange, and is combined with the corresponding terminal 13 through a crimping process; the bottoms of the spring claws 141 at both ends (not shown in the figure) are respectively welded to the support body 121, and the fuse 15 is clamped between the two spring claws 141; any end cover 112 is screwed to the corresponding flange, and the tube 111 is inserted into the slot 1121 of the cover 112 (not shown in the figure), and the slot 1121 of the other end cover 112 is aligned with the tube 111 and screwed to the corresponding flange; the two sealing rings 16 are screwed to the corresponding cover 112 respectively.

[0074] When the current passing through the wiring harness exceeds the specified limit, the fuse 15 blows. When replacing the fuse 15, the wiring harness fuse 10 is disassembled. The disassembly process is the opposite of the above-mentioned assembly process and will not be described in detail here.

[0075] Example 2

[0076] Wiring harnesses are key components in the power transmission of automotive electrical systems, providing energy to various electrical devices throughout the vehicle. As the primary carrier of electrical power and power transmission, wiring harnesses require excellent insulation and voltage resistance, and must be able to safely, stably, and reliably conduct high currents.

[0077] The fuse is placed at the positive circuit output end of the main circuit in the high-voltage electrical architecture of the battery pack. At this stage, the energy density of power batteries is getting higher and higher, and the capacity of single cells is getting larger and larger. Once a short circuit occurs in the electrical components without corresponding protection measures, the components may be damaged at the least, and the consequences may be unimaginable, such as a fire. Therefore, the protection of each wiring harness is crucial.

[0078] Wiring harnesses and fuses are both essential components of a vehicle's electrical system. In the prior art, each branch fuse for an electrical appliance in a vehicle often needs to be housed in a separate fuse box, which wastes space. Considering the limited space in the vehicle, electrical safety, and maintaining the full functionality of the wiring harness and fuse, this embodiment provides an automobile comprising a wiring harness and the wiring harness fuse provided in Example 1.

[0079] It should be noted that the car can be a gasoline car or a new energy vehicle. The car includes the wiring harness fuse as described in the above embodiment. The wiring harness fuse can be flexibly fixed and arranged in a convenient maintenance position of the vehicle. It not only effectively realizes the stable transmission of electricity, but also integrates the function of the protection circuit on the wiring harness. A separate fuse container is no longer required to arrange the fuse, which greatly saves the installation space of the fuse and the installation space of the surrounding fixed accessories, improves space utilization, reduces weight, shortens design costs and development cycles. When the short-circuit fuse 15 is disconnected, the housing can be quickly disassembled and the fuse can be quickly replaced by clamping the clamp with the fuse, which greatly reduces the difficulty and time cost of fuse maintenance and replacement. At the same time, the assembly is simple and reliable, which improves the manufacturing and assembly efficiency.

[0080] According to a specific implementation of the present invention, each terminal and the corresponding wire harness are combined through a crimping process.

[0081] With this design, the stability of the connection between the wiring harness and the terminal is improved, thereby ensuring the normal operation of the vehicle electrical system.
