Summary of the Invention

Problems to be Solved by the Invention

[0006] As described above, when a blade fuse or a cartridge fuse blows during vehicle travel, the blown blade fuse or cartridge fuse can be pulled out and replaced with a spare blade fuse or a blade fuse adapter, enabling emergency measures to be taken.

[0007] However, for the replacement work of the above blade fuses and the like, a dedicated tool such as a fuse puller for pulling out the above blade fuses and the like is required. Also, in order to improve the electrical reliability during the use of the above blade fuses, the above blade fuses are in a state of being firmly fitted to the blade fuse housing. Therefore, in order to remove the blade fuse from the blade fuse housing without damaging the blade fuse housing, careful and multi-step operations are required, resulting in the problems of complicated work and time consumption.

[0008] Also, during the work of transporting the completed vehicle from the manufacturer's assembly plant to the dealership or the like, at a minimum, it is sufficient to supply power to the electronic control device that controls the vehicle's travel, stop, or steering. However, as described above, due to the complication of the fuse detachment work, even for the power circuit of the car navigation device or the like before installation in the vehicle, the fuse is pre-installed in the energized state, resulting in a leakage current flowing. As a result, there is a problem that it is difficult to achieve power saving during the above transport work.

[0009] The present invention has been made in view of the above circumstances, and an object thereof is to provide a vehicle fuse box that simplifies the work of disconnecting the fuse from the terminal of the housing part and realizes power saving during vehicle transport work.

Means for Solving the Problems

[0010] In a vehicle fuse box according to an embodiment of the present invention, there is provided a vehicle fuse box including a housing portion that supports a fuse disposed in a circuit for supplying power from a vehicle battery to an electronic control unit, wherein at least a part of the fuse is disposed inside the housing portion, and the fuse box has a fuse removal jig for detaching a terminal portion of the fuse from a housing-side terminal portion of the housing portion. The fuse removal jig includes a main body portion movable inside the housing portion, an operation portion formed on a first end side of the main body portion, and a protrusion portion formed on the main body portion. In a state where the terminal portion of the fuse is connected to the housing-side terminal portion, when the operation portion is operated, the main body portion moves inside the housing portion, the protrusion portion moves the fuse, and the terminal portion of the fuse becomes non-connected to the housing-side terminal portion.

Advantages of the Invention

[0011] In a vehicle fuse box according to an embodiment of the present invention, a fuse and a fuse removal jig are disposed inside a housing portion. By operating an operation portion of the fuse removal jig by an operator, a protrusion portion of the fuse removal jig moves the fuse, and a terminal portion of the fuse becomes non-connected to a housing-side terminal portion. With this structure, the operator can achieve the non-connection state of the fuse by a simple operation of operating the operation portion, so that power saving during vehicle transportation work can be easily achieved.

Mode for Carrying Out the Invention

[0013] Hereinafter, a vehicle fuse box 10 according to an embodiment of the present invention will be described in detail with reference to the drawings. In the description of this embodiment, the same reference numerals are generally used for the same members, and repeated descriptions are omitted.

[0014] FIG. 1 is a perspective view illustrating the vehicle fuse box 10 of this embodiment. FIG. 2A is a top view illustrating the fuse removal jig 17 used in the vehicle fuse box 10 of this embodiment. FIG. 2B is a bottom view illustrating the fuse removal jig 17 used in the vehicle fuse box 10 of this embodiment. FIG. 2C is a side view illustrating the fuse removal jig 17 used in the vehicle fuse box 10 of this embodiment.

[0015] Examples of vehicles (not shown) that use the vehicle fuse box 10 include, for example, BEV (Battery Electric Vehicle), HEV (Hybrid Electric Vehicle), and PHEV (Plug-in Hybrid Electric Vehicle). Note that the vehicle is not limited to the above electric vehicles, but also includes vehicles that run on an internal combustion engine using fuel such as gasoline.

[0016] As shown in FIG. 1, the vehicle fuse box 10 includes, for example, a plurality of fuses 11, a plurality of housing portions 12 that individually house the plurality of fuses 11, a first housing-side terminal portion 15 (see FIG. 3B) that connects to the first terminal portion 13 (see FIG. 3B) of the fuse 11, a second housing-side terminal portion 16 (see FIG. 3B) that connects to the second terminal portion 14 (see FIG. 3B) of the fuse 11, and a fuse removal jig 17 that moves the fuse 11 inside the housing portion 12. Note that, as the first housing-side terminal portion 15, the terminal portion at the tip of the first harness 31 (see FIG. 3C) is used, and as the second housing-side terminal portion 16, the terminal portion at the tip of the second harness 32 (see FIG. 3C) is used.

[0017] Although not shown, the first terminal portion 13 of the fuse 11 is formed, for example, at the end of an elongated recess 33 (see FIG. 3B) formed in the fuse 11 corresponding to the shape of the first harness 31. Similarly, the second terminal portion 14 of the fuse 11 is formed at the end of the elongated recess 33 formed in the fuse 11 corresponding to the shape of the second harness 32. Then, when the fuse 11 is inserted to the end and fitted to the terminal portions at the tips of the first and second harnesses 31 and 32, the first and second terminal portions 13 and 14 of the fuse 11 are connected to the first and second housing-side terminal portions 15 and 16 of the housing portion 12.

[0018] The first terminal portion 13 of the fuse 11 is connected to the battery 18 (see FIG. 3C) via the first harness 31. On the other hand, the second terminal portion 14 of the fuse 11 is connected to the electronic control unit 19 (see FIG. 3C) via the second harness 32. Then, when the fuse 11 is connected to the first housing-side terminal portion 15 and the second housing-side terminal portion 16, power is supplied from the battery 18 to the electronic control unit 19. On the other hand, when the fuse 11 is disconnected from the first housing-side terminal portion 15 and the second housing-side terminal portion 16, the supply of power from the battery 18 to the electronic control unit 19 is interrupted.

[0019] In the vehicle, as the electronic control unit 19, there are an electronic control unit 19 of the first load group that controls the running, stopping, or steering of the vehicle, and an electronic control unit 19 of the second load group that realizes the comfort of the vehicle occupants and the like. And in this embodiment, as the electronic control unit 19 of the first load group, for example, there are an alternator, an anti-skid device, an electric brake, an electric power steering, and the like. On the other hand, as the electronic control unit 19 of the second load group, for example, there are an air conditioner, a navigation device, a seat heater, an interior light, and the like.

[0020] As shown in FIGS. 2A and 2B, the fuse removal jig 17 is integrally formed of a thermoplastic resin such as polyethylene or polypropylene. And the shape of the fuse removal jig 17 is, for example, a strip shape, and it is a shape that bends and displaces when a certain external force is applied.

[0021] The fuse removal jig 17 includes a main body portion 21, an operation portion 22 formed on the first end portion 21A side of the main body portion 21, a first slit structure 23, a second slit structure 24, and a third slit structure 25 formed at intervals in the longitudinal direction of the main body portion 21, and a protrusion 26 formed in the first slit structure 23.

[0022] The main body portion 21 is formed as a strip extending with a constant width W1. Although details will be described later, the thickness T1 of the main body portion 21 (see FIG. 2C) is formed to be thin within a range that ensures the rigidity to lift the fuse 11 at the protrusion portion 26. With this structure, when the fuse detachment jig 17 is disposed inside the housing portion 12, the main body portion 21 can be bent and displaced while being guided by the inner surface 12C of the housing portion 12.

[0023] The operation portion 22 is formed on the first end portion 21A side of the main body portion 21. And the thickness T2 of the operation portion 22 is formed thicker than the thickness T1 of the main body portion 21. As shown in FIG. 2C, the operation portion 22 is formed to be bent at a substantially right angle with respect to the extending direction of the main body portion 21. Although details will be described later, the fuse detachment jig 17 is disposed in the housing portion 12, and when an operator presses the operation portion 22 downward with a finger, the main body portion 21 inside the housing portion 12 is slid and moved toward the second end portion 21B side.

[0024] The first slit structure 23 is formed on the first end portion 21A side of the main body portion 21 and has a plurality of slits 23A on the front surface side of the main body portion 21 and a plurality of slits 23B on the back surface side of the main body portion 21. And since the slits 23A and 23B are formed to face the front and back surface sides of the main body portion 21, the amount of bending of the main body portion 21 in the formation region of the first slit structure 23 increases and it becomes easier to shift. As shown in FIG. 2C, the slits 23A and 23B are each formed in a state parallel to the longitudinal direction of the main body portion 21. And the pitch W2 of the slits 23A is formed, for example, with a width about 1 / 2 of the pitch W3 of the slits 23B.

[0025] The second slit structure 24 is formed in the central portion of the main body 21, and includes a plurality of slits 24A on the front surface side of the main body 21 and a plurality of slits 24B on the back surface side of the main body 21. The slits 24A and 24B are formed to face the front and back surface sides of the main body 21, so that the amount of deflection of the main body 21 in the formation region of the second slit structure 24 increases and it becomes easier to transition. As shown in FIG. 2C, the slits 24A and 24B are each formed in a state parallel to the longitudinal direction of the main body 21. Similar to the first slit structure 23, the pitch W2 of the slits 24A is formed, for example, with a width approximately half that of the pitch W3 of the slits 24B.

[0026] The third slit structure 25 is formed on the second end portion 21B side of the main body 21, and includes a plurality of slits 25A on the front surface side of the main body 21 and a plurality of slits 25B on the back surface side of the main body 21. The slits 25A and 25B are formed to face the front and back surface sides of the main body 21, so that the amount of deflection of the main body 21 in the formation region of the third slit structure 25 increases and it becomes easier to transition. As shown in FIG. 2C, the slits 25A and 25B are each formed in a state parallel to the longitudinal direction of the main body 21. Similar to the first slit structure 23, the pitch W2 of the slits 25A is formed, for example, with a width approximately half that of the pitch W3 of the slits 25B.

[0027] The protrusion 26 is on the front surface side of the main body 21 and is formed, for example, within the formation region of the slit 23A of the first slit structure 23. The protrusion 26 is formed, for example, in a substantially triangular shape in cross-section and extends across the short side direction of the main body 21. Although details will be described later, within the housing portion 12, when the protrusion 26 moves from the side surface 11D to the bottom surface 11A side of the outer peripheral surface 11B of the fuse 11, the fuse 11 is lifted upward with respect to the housing portion 12. Then, as the fuse 11 moves upward, the first and second terminal portions 13 and 14 of the fuse 11 are each in a non-connected state with the first and second housing-side terminal portions 15 and 16. As a result, the fuse 11 is in an electrically non-conductive state with the battery 18 and the electronic control device 19.

[0028] Next, with reference to FIGS. 3A to 5B, a process in which the first and second terminal portions 13 and 14 of the fuse 11 of the vehicle fuse box 10 of the present embodiment are detached from the first and second housing-side terminal portions 15 and 16 and become non-connected in a state where the fuse 11 is mounted on the housing portion 12 will be described.

[0029] FIG. 3A is a front view for explaining a state in which the first and second terminal portions 13 and 14 of the fuse 11 mounted on the housing portion 12 of the vehicle fuse box 10 of the present embodiment are connected to the first and second housing-side terminal portions 15 and 16. FIG. 3B is a side view for explaining the housing portion 12 shown in FIG. 3A. FIG. 3C is a top view for explaining the housing portion 12 shown in FIG. 3A. FIG. 4A is a cross-sectional view for explaining the internal structure of the housing portion 12 shown in FIG. 3A, showing a cross-section in the direction of line A-A in FIG. 3B. FIG. 4B is a cross-sectional view for explaining the internal structure of the housing portion 12 shown in FIG. 3A, showing a cross-section in the direction of line B-B in FIG. 3A. FIG. 5A is a cross-sectional view for explaining a process in which the first and second terminal portions 13 and 14 of the fuse 11 of the present embodiment become non-connected to the first and second housing-side terminal portions 15 and 16, showing a cross-section corresponding to the cross-section in FIG. 4A. FIG. 5B is a cross-sectional view for explaining a process in which the first and second terminal portions 13 and 14 of the fuse 11 of the present embodiment become non-connected to the first and second housing-side terminal portions 15 and 16, showing a cross-section corresponding to the cross-section in FIG. 4B. In FIG. 3B, for convenience of explanation, portions of the first and second harnesses 31 and 32 inserted into the housing portion 12 are also shown by solid lines.

[0030] As shown in FIG. 3A, a plurality of housing portions 12 are formed on the upper surface of the vehicle fuse box 10. The frame portion 10A of the vehicle fuse box 10 is integrally formed with the housing portion 12 by resin molding. Then, a plurality of fuses 11 are respectively mounted on the individual housing portions 12. In the present embodiment, in a state where the first and second terminal portions 13 and 14 of the fuse 11 are connected to the first and second housing-side terminal portions 15 and 16, the entire fuse 11 is in a state of being housed inside the housing portion 12.

[0031] Further, a guide portion 12A that protrudes inward of the housing portion 12 is formed at the upper end portion 12D of the housing portion 12. The guide portion 12A is integrally formed with the housing portion 12 by resin molding. And the guide portion 12A is formed in a substantially L-shaped cross section, for example. The tip side of the guide portion 12A is formed toward the inside of the housing portion 12 and has a shape that protrudes above the fuse 11 mounted on the housing portion 12.

[0032] As shown in FIG. 3B, the fuse removal jig 17 is disposed at the central portion of the housing portion 12. And the operation portion 22 formed on the first end portion 21A side of the main body portion 21 is led out above the upper end portion 12D of the housing portion 12. On the other hand, the main body portion 21 is wired inside the housing portion 12 along the outer peripheral surface 11B of the fuse 11, and the second end portion 21B side of the main body portion 21 is disposed near the upper end portion 12D of the housing portion 12. That is, the fuse 11 is disposed between the main body portions 21 disposed in the housing portion 12 in a substantially U-shaped cross section view.

[0033] As shown in the drawing, the terminal portion at the tip of the first harness 31 is fixed at a desired position inside the housing portion 12 and is used as the first housing-side terminal portion 15. Similarly, the terminal portion at the tip of the second harness 32 is fixed at a desired position inside the housing portion 12 and is used as the second housing-side terminal portion 16.

[0034] As shown in FIG. 3C, in each housing portion 12 of the vehicle fuse box 10, the first harness 31 connected to the battery 18 is wired from the bottom surface side of the housing portion 12 to the inside of the housing portion 12 via the inside of the frame portion 10A. Similarly, the second harness 32 connected to the electronic control device 19 is wired from the bottom surface side of the housing portion 12 to the inside of the housing portion 12 via the inside of the frame portion 10A. The fuse 11 is disposed between the power circuits of the battery 18 and the electronic control device 19. And when the first and second terminal portions 13, 14 of the fuse 11 are connected to the first and second housing-side terminal portions 15, 16, power is supplied from the battery 18 to the electronic control device 19.

[0035] As shown in FIG. 4A, the fuse 11 is inserted into the housing 12 from the upper opening 12B of the housing 12. Then, by inserting the first and second terminal portions 13, 14 of the fuse 11 into the first and second housing-side terminal portions 15, 16, the fuse 11 is fixed at a desired position inside the housing 12. In this embodiment, when the fuse 11 is inserted to the end with respect to the first and second housing-side terminal portions 15, 16, the first and second terminal portions 13, 14 of the fuse 11 and the first housing-side terminal portion 15 and the second housing-side terminal portion 16 are electrically connected.

[0036] On the other hand, as shown in FIGS. 4A and 4B, the fuse removal jig 17 is inserted into the housing 12 from the central portion of the housing 12, and most of the main body portion 21 is disposed inside the housing 12 along the outer peripheral surface 11B of the fuse 11. As described above, the main body portion 21 of the fuse removal jig 17 has a strip shape and is disposed between the fuse 11 and the inner surface 12C of the housing 12. And even when the first and second terminal portions 13, 14 of the fuse 11 are connected to the first and second housing-side terminal portions 15, 16, the fuse removal jig 17 is disposed inside the housing 12.

[0037] Further, a first slit structure 23, a second slit structure 24, and a third slit structure 25 are formed in the main body portion 21. In a state where the fuse removal jig 17 is disposed in the housing 12, the first slit structure 23 is disposed corresponding to the corner portion 12E on the lower end side of the housing 12. The second slit structure 24 is disposed corresponding to the corner portion 12F on the lower end side of the housing 12. The third slit structure 25 is disposed corresponding to the guide portion 12A.

[0038] As described above, in the first to third slit structures 23, 24, and 25, the pitch W2 of the slits 23A, 24A, 25A is narrower than the pitch W3 of the slits 23B, 24B, 25B. With this structure, the main body portion 21 is disposed along the inner surface 12C of the housing portion 12, and at the corner portions 12E, 12F on the lower end side of the housing portion 12, it bends and displaces along its shape. With this structure, the main body portion 21 bends more on the front surface side than on the back surface side, and as described above, the main body portion 21 is disposed along the outer peripheral surface 11B of the fuse 11.

[0039] In the present embodiment, the protrusion 26 is formed within the first slit structure 23 of the main body portion 21. And when the fuse 11 is in the above connection state, the position of the main body portion 21 is adjusted so that the protrusion 26 is located on the side surface 11D around the corner portion 11C of the fuse 11. As a result, the operation portion 22 is disposed at a position having a separation distance L1 upward from the upper end portion 12D of the housing portion 12. On the other hand, the second end portion 21B of the main body portion 21 is disposed at substantially the same position as the upper end portion 12D of the housing portion 12, or at a position derived slightly from the upper end portion 12D.

[0040] Next, as shown in FIG. 5A, when the operation portion 22 is pushed into the inside of the housing portion 12, the first and second terminal portions 13, 14 of the fuse 11 become non-connected to the first housing-side terminal portion 15 and the second housing-side terminal portion 16. Specifically, when the operation portion 22 is pushed in by the separation distance L1, the main body portion 21 slides and moves along the inner surface 12C of the housing portion 12 by the same distance toward the second end portion 21B side. And when the protrusion 26 moves from the side surface 11D of the fuse 11 toward the bottom surface 11A side, the protrusion 26 lifts the bottom surface 11A of the fuse 11 upward.

[0041] As a result, the fuse 11 moves upward inside the housing portion 12 by the height of the protrusion 26, and the first and second terminal portions 13, 14 of the fuse 11 are detached from the first and second housing-side terminal portions 15, 16. Then, when the first and second terminal portions 13, 14 of the fuse 11 are in a non-connected state with the first and second housing-side terminal portions 15, 16, the fuse 11 becomes non-conductive with respect to the battery 18 and the electronic control device 19.

[0042] At this time, in the fuse removal jig 17, the main body portion 21 slides inside the housing portion 12, and the second end portion 21B of the main body portion 21 and its peripheral region are led out from the housing portion 12 toward the guide portion 12A. As shown in the figure, a third slit structure 25 is formed in the peripheral region of the second end portion 21B of the main body portion 21, so that the peripheral region of the second end portion 21B of the main body portion 21 protrudes upward along the guide portion 12A toward the fuse 11.

[0043] With this structure, at least a part of the top surface of the fuse 11 is covered by the peripheral region of the second end portion 21B of the main body portion 21. For example, even when the fuse 11 is pushed by the protrusion 26 and bounces upward inside the housing portion 12, the fuse 11 comes into contact with the peripheral region of the second end portion 21B of the main body portion 21, and it is prevented from falling out of the housing portion 12. As a result, even in the above non-connected state, the fuse 11 is maintained in a state of being mounted inside the housing portion 12, and the fuse 11 is prevented from being lost. And there is no need to separately manage the fuse 11 removed from the housing portion 12.

[0044] In addition, as described above, even when the fuse 11 is in the above non-connected state, the fuse 11 is also prevented from falling out by being hooked on the first and second housing-side terminal portions 15, 16 through the recess 33.

[0045] In this embodiment, when the fuse 11 is mounted on the housing portion 12, the operator can make the first and second terminal portions 13 and 14 of the fuse 11 be in a non-connected state with respect to the first and second housing-side terminal portions 15 and 16 by pushing in the operation portion 22 of the fuse removal jig 17. That is, the operator can realize the non-connected state of the fuse 11 by pushing in the operation portion 22 pre-arranged on the housing portion 12, so that the work is simplified and the working time is significantly reduced.

[0046] Also, when the operator returns the fuse 11 from the non-connected state to the connected state, it is also possible to cope with it by an operation of pushing the fuse 11 into the inside of the housing portion 12 while pulling the operation portion 22 upward, and the work becomes easy.

[0047] Also, during the work of transporting the completed vehicle from the manufacturer's assembly factory to the dealership or the like, the operator can cut off the power supply to the electronic control device 19 of the second load group described above by a simple operation of pushing in the operation portion 22. As a result, the generation of dark current during the above-mentioned transport work is prevented, and power saving is realized.

[0048] Furthermore, during the above-mentioned transport work, due to vibrations during running or the like being applied to the completed vehicle, the fuse 11 in the non-connected state may bounce inside the housing portion 12, but it is suppressed by the fuse removal jig 17 and maintained in a state of being mounted inside the housing portion 12. As a result, the fuse 11 is prevented from falling out of the housing portion 12, and the loss of the fuse 11 is prevented.

[0049] Note that, in this embodiment, the case where the protrusion 26 is arranged with respect to the formation region of the first slit structure 23 of the main body portion 21 has been described, but it is not limited to this case. At least, it may be formed on the main body portion 21 at a position where the bottom surface 11A of the fuse 11 can be lifted within the range of the length by which the main body portion 21 slides. In addition, various modifications are possible without departing from the gist of the present invention.
