[Diagram 3] FIG. 3 is a diagram illustrating the electrical junction box cover laminate according to the present embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to this embodiment. In addition, the components in the following embodiments include those that are replaceable and easy for a person skilled in the art, or those that are substantially the same.

[0011] 1 to 3 are schematic diagrams showing the configuration of tapered portions (first taper 221 and second taper 222) provided in electric junction box cover 200. Therefore, for the sake of convenience of explanation, walls constituting electric junction box cover 200 are partially omitted in Figs. 1 to 3.

[0012] [Embodiment] The electrical junction box cover 200 shown in FIG. 1 is a lid member for an electrical junction box 1 that houses therein electronic components such as connectors, fuses, relays, capacitors, branches, electronic control units, and electronic component units that combine these components into a single unit.

[0013] The electric junction box cover 200 of this embodiment is configured to improve efficiency during transportation by overlapping (stacking) the first taper 221 and the second taper 222 provided on the side wall 220 so as to abut against each other. Each component of the electric junction box cover 200 will be described in detail below with reference to FIG. 1.

[0014] In the following description, the three mutually intersecting directions are conveniently referred to as the "depth direction X," the "width direction Y," and the "height direction Z." The depth direction X, the width direction Y, and the height direction Z are mutually perpendicular. The depth direction X and the width direction Y typically correspond to the horizontal direction. The height direction Z typically corresponds to the vertical direction, and corresponds to the opening direction of the opening 100K of the housing main body 100, the extension direction of the side wall 220 of the electric junction box cover 200, the stacking direction of the electric junction box cover 200, and the like. In the vertical direction, the upper side is referred to as the upper portion or the upper side, and the lower side in the vertical direction is referred to as the lower portion or the lower side.

[0015] The electrical connection box 1 is made of an insulating resin material and includes a housing body 100 in which an electronic component D is housed, an electrical connection box cover 200 as an upper cover attached to the upper part of the housing body 100, and a lower cover attached to the lower part of the housing body 100. The housing body 100 here is a member constituting the main body of the electrical connection box 1, and is also called a frame. The electrical connection box cover 200 as an upper cover is a lid-like member that closes an upper opening 100K of the housing body 100, and is also called an upper cover. The lower cover is a lid-like member that closes an opening (not shown) on the lower side of the housing body 100, and is also called a lower cover. The housing body 100 is formed into a substantially rectangular cylindrical shape by opening the upper and lower sides in the height direction Z and being surrounded by side walls all around including the depth direction X and width direction Y, and a space portion located inside the lid forms a part of the storage space portion. The upper cover and the lower cover are fitted to the side walls of the housing body 100 and are attached via various locking mechanisms. Therefore, when the upper cover and the lower cover are attached to the housing body 100, the opening of the housing body 100 can be blocked, and the space located inside the cover forms a part of the storage space. The electric connection box 1 having such a configuration is installed, for example, in an engine room or a vehicle cabin of a vehicle by being incorporated into a wire harness. The electric connection box 1 is connected between a power source such as a battery and various electronic devices mounted in the vehicle via wiring materials or the like. Therefore, the electric connection box 1 can distribute power supplied from the power source to various electronic devices in the vehicle. The electric connection box 1 may also be called a junction box, a fuse box, a relay box, or the like, but in this embodiment, these are collectively called an electric connection box. The wire harness to which the electric connection box 1 is applied is, for example, a wire harness in which a plurality of wiring materials used for power supply and signal communication are connected to each device by a connector or the like in order to connect each device mounted in the vehicle. The wire harness may further include a grommet, a protector, a fastener, and the like.

[0016] 1, the electrical junction box cover 200 includes a main wall 210 and a plurality of side walls 220. The electrical junction box cover 200 is formed such that the main wall 210 and the plurality of side walls 220 are integrally formed.

[0017] The main wall 210 is a wall portion that covers the upper opening 100K of the housing body 100 when assembled to the upper part of the housing body 100. The main wall 210 of this embodiment is formed in a substantially rectangular plate shape that extends along the depth direction X and width direction Y and has a plate thickness direction in the height direction Z.

[0018] As shown in FIG. 1, the main wall 210 of this embodiment includes a printed portion 211.

[0019] The printed section 211 is a portion on which information on the electronic component D accommodated inside the housing body 100 is printed. The printed section 211 of this embodiment is provided on the inner surface 210Sb side of the main wall 210 located opposite the opening 100K of the housing body 100 when the electric junction box cover 200 is attached to the upper part of the housing body 100. In addition, the printed section 211 is printed with the types of fuses, relays, etc. and circuit names. Therefore, a worker performing maintenance work can check which circuit has been blown by looking at the printed section 211 when a fuse is blown due to a short circuit, for example. In addition, by checking the type of blown fuse on the printed section 211, the worker can perform maintenance work without looking at a maintenance manual, etc., thereby improving work efficiency during maintenance.

[0020] The side walls 220 are walls extending from the outer edge of the main wall 210. In this embodiment, four side walls 220 are provided on each of the four sides of the main wall 210 formed in a substantially rectangular plate shape. The four side walls 220 are formed in a substantially rectangular tube shape by connecting a pair of side walls 220 arranged at an interval along the depth direction X and a pair of side walls 220 arranged at an interval along the width direction Y to each other and integrally forming the four side walls 220. The four side walls 220 have an opening 200K formed by lower ends 220b in the height direction Z.

[0021] In addition, the side wall 220 of this embodiment is configured to include a first taper 221 and a second taper 222, as shown in FIG.

[0022] The first taper 221 is a tapered portion provided on the main wall 210 side. The first taper 221 of this embodiment is formed at a corner portion 220a located between the main wall 210 and the main wall 210, and is provided over the entire periphery of the main wall 210 which is formed in a substantially rectangular shape.

[0023] 1, the first tapers 221 are inclined so as to move away from the main wall 210. Therefore, the first tapers 221 provided on a pair of side walls 220 spaced apart along the width direction Y are inclined from the inner side toward the outer side in the width direction Y (see FIG. 1). Furthermore, the first tapers 221 provided on a pair of side walls 220 spaced apart along the depth direction X are inclined from the inner side toward the outer side in the depth direction X. Therefore, the pair of first tapers 221 arranged opposite to each other in the width direction Y (or the depth direction X) are inclined so that the distance between them increases from the upper side toward the lower side in the height direction Z.

[0024] The second taper 222 is a taper portion provided on the side opposite to the main wall 210. As shown in Fig. 1, the first taper 221 in this embodiment is formed on the end portion 220b on the side opposite to the main wall 210, and is provided around the entire periphery of the wall portion formed into a substantially rectangular tubular shape by the multiple side walls 220.

[0025] Similarly to the first taper 221, the second taper 222 is inclined from the inner side to the outer side in the width direction Y (or the depth direction X). Therefore, a pair of second tapers 222 arranged opposite to each other in the width direction Y (or the depth direction X) are inclined from the upper side to the lower side in the height direction Z so that the distance between them increases.

[0026] The inclination angles of the first taper 221 and the second taper 222 are equal to each other and are set to a predetermined angle.

[0027] Next, with reference to Figs. 2 and 3, an electric junction box cover laminate B formed by laminating a plurality of electric junction box covers 200 will be described.

[0028] First, the worker prepares a plurality of electric junction box covers 200.

[0029] Then, the worker stores the electric junction box cover 200 in a storage case A (see FIG. 3) to be used during transportation, and places it with the opening 200K side facing down and the main wall 210 side facing up.

[0030] Then, as shown in Figure 2, the worker places the multiple electrical junction box covers 200 in a state in which the lower surface 222Sb of the second taper 222 of the upper electrical junction box cover 200 abuts the upper surface 221Sa of the first taper 221 of the lower electrical junction box cover 200.

[0031] At this time, as shown in Fig. 2, the multiple electric junction box covers 200 are stacked (pile up) on the main wall 210 of the electric junction box cover 200 placed in a predetermined place. The multiple electric junction box covers 200 are placed and stacked in a state in which the tip end (the outer end in the width direction Y or the depth direction X) of the second taper 222 of the electric junction box cover 200 located on the upper side and the base end (the inner end in the width direction Y or the depth direction X) of the first taper 221 of the electric junction box cover 200 located on the lower side overlap and contact each other in the height direction Z. Therefore, the multiple electric junction box covers 200 can each sufficiently secure contact points with the electric junction box covers 200 located adjacent to each other vertically, and thus it is possible to suppress the occurrence of positional deviation due to vibration during transportation, etc.

[0032] Moreover, the multiple electric junction box covers 200 are placed with the lower end 220b of the side wall 220 of the upper electric junction box cover 200 in contact with the corner 220a formed at the upper end of the lower electric junction box cover 200, so that the main wall 210 of the upper electric junction box cover 200 is placed away from the main wall 210 of the lower electric junction box cover 200. Therefore, the multiple electric junction box covers 200 are placed and stacked with a space formed between the printed portion 211 provided on the inner surface 210Sb side of the main wall 210 of the upper electric junction box cover 200 and the outer surface 210Sa of the main wall 210 of the lower electric junction box cover 200.

[0033] 3, the worker stacks six electric junction box covers 200 in the height direction Z to create an electric junction box cover laminate B. The worker then creates a plurality of electric junction box cover laminates B in the same procedure, thereby storing a preset number of electric junction box covers 200 in the storage case A. Note that the number of electric junction box covers 200 stacked in the height direction Z and the number of electric junction box cover laminates B stored in the storage case A are not particularly limited, and can be set in accordance with the specifications of the electric junction box covers 200 and the specifications of the storage case A.

[0034] The electric junction box cover 200 described above is configured to include a main wall 210 that covers the opening 100K of the housing main body 100 in which the electronic component D is housed, and a plurality of side walls 220 that extend from the outer edge of the main wall 210 along the height direction Z that is the opening direction of the opening 100K and are assembled to the housing main body 100. Moreover, the side wall 220 of the electric junction box cover 200 has a first taper 221 formed at a corner 220a with the main wall 210 and a second taper 222 formed at an end 220b opposite to the main wall 210.

[0035] Furthermore, the electrical junction box cover laminate B described above is formed by stacking one electrical junction box cover 200 in a state in which the second taper 222 of the one electrical junction box cover 200 is in contact with the first taper 221 of another electrical junction box cover 200 positioned adjacent to the one electrical junction box cover 200.

[0036] According to this configuration, the electric junction box cover 200 is formed in a stackable shape. In addition, the second taper 222 of the electric junction box cover 200 newly stacked on the outer surface 210Sa side of the main wall 210 of the electric junction box cover 200 is stacked in a state of contact with the first taper 221 of the electric junction box cover 200 already placed, so that the contact points with the adjacent electric junction box covers 200 can be sufficiently secured. Therefore, the electric junction box cover laminate B formed by stacking a plurality of electric junction box covers 200 can suppress the position of the stacked electric junction box covers 200 from being shifted due to vibration during transportation. And, the electric junction box cover laminate B can transport each of the electric junction box covers 200 in a proper state by suppressing the occurrence of collapse during transportation. Therefore, the electric junction box cover laminate B and the electric junction box cover 200 of this embodiment can improve the efficiency during transportation.

[0037] Generally, when electrical junction box covers that do not have tapered portions (first taper 221, second taper 222) are transported in a stacked state, the electrical junction box covers cannot be sufficiently secured to contact each other, and thus the position may shift during transportation, causing the load to collapse. Therefore, when stacking a plurality of electrical junction box covers, the electrical junction box covers and the partition plates are stacked alternately to improve the stability of the stacked electrical junction box covers and prevent the load from collapsing. However, when the electrical junction box covers are stacked using the partition plates, the electrical junction box covers can be transported in an organized (properly stacked) state, but the electrical junction box covers must be transported using the partition plates, which consumes more space in the storage case A and reduces the space efficiency of the storage case A (the storage ability of the electrical junction box covers). Therefore, by modifying the electrical junction box cover 200 of this embodiment to a stackable shape and providing tapered portions (first taper 221, second taper 222) so that it can be transported in the proper condition without using a partition plate, the storage ability of the electrical junction box cover can also be improved.

[0038] Furthermore, in each of the electric junction box covers 200 constituting the electric junction box cover laminate B described above, the first taper 221 is provided over the entire circumference of the corner portion 220a formed between the main wall 210 and the rectangular-shaped cover, and the second taper 222 is provided over the entire circumference (the plurality of ends 220b) of the end portion of the wall portion formed into a rectangular tube by the plurality of side walls 220. According to this configuration, the first taper 221 and the second taper 222 are each provided over the circumferential direction of the electric junction box cover 200, thereby improving the stability when the plurality of electric junction box covers 200 are stacked. Therefore, the electric junction box cover laminate B formed by stacking the plurality of electric junction box covers 200 can more reliably suppress the position of the electric junction box cover 200 from being displaced due to vibrations during transportation, etc. Furthermore, the electric junction box cover laminate B can more reliably suppress the occurrence of load collapse during transportation, thereby allowing each of the electric junction box covers 200 to be transported in a proper state. Therefore, the electric junction box cover laminate B and the electric junction box cover 200 of this embodiment can further improve efficiency during transportation.

[0039] Furthermore, each of the plurality of electric junction box covers 200 constituting the electric junction box cover laminate B described above has a printed portion 211 provided on the inner surface 210Sb side of the main wall 210, on which information on the electronic component D is printed. Moreover, each of the plurality of electric junction box covers 200 is laminated in a state in which a space is formed between the printed portion 211 of one electric junction box cover 200 and the main wall 210 of another electric junction box cover 200 positioned adjacent to the one electric junction box cover 200. With this configuration, it is possible to prevent the printed portion 211 of the electric junction box cover 200 from being damaged during transportation, and it is possible to prevent various information written on the printed portion 211 from becoming difficult to read. Therefore, the electric junction box cover laminate B and the electric junction box cover 200 of this embodiment can improve the work efficiency during maintenance.

[0040] Furthermore, the electrical junction box cover laminate B and the electrical junction box cover 200 according to the above-described embodiment of the present invention are not limited to the above-described embodiment, and various modifications are possible within the scope of the claims.

[0041] For example, the stacking direction of the electric junction box cover 200 has been described as the height direction Z (vertical direction), but the direction is not particularly limited. Also, the position and orientation of the electric junction box cover laminate B stored in the storage case A are not particularly limited to the form shown in FIG.

[0042] Furthermore, the position of the first taper 221 and the position of the second taper 222 are not particularly limited.

[0043] Furthermore, the electric junction box cover laminate B according to this embodiment and the electric junction box cover 200 may be constructed by appropriately combining the components of the embodiments and modified examples described above. [Explanation of symbols]
