[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to these embodiments. Furthermore, the components in the following embodiments include those that are easily replaceable by those skilled in the art, or those that are substantially the same.

[0010] [First embodiment] The electrical junction box 1 according to this embodiment is mounted on a vehicle such as an automobile and incorporated into a wire harness.

[0011] A wire harness is, for example, a component made by bundling wiring materials used for power supply and signal communication to connect various devices mounted on a vehicle, and connecting the wiring materials to the various devices with connectors or the like. The wire harness is configured to include conductive wiring materials and an electrical junction box 1 that is electrically connected to the wiring materials. In addition to these, the wire harness may also be configured to include protectors, exterior materials, fixtures, etc.

[0012] The electrical junction box 1 houses electronic components such as connectors, fuses, relays, capacitors, branching sections, electronic control units, and electronic component units that combine these components. The electrical junction box 1 is installed, for example, in the engine compartment or interior of a vehicle. The electrical junction box 1 is connected between a power source such as a battery and various electronic devices installed in the vehicle via wiring materials, etc., and distributes power supplied from the power source to the various electronic devices in the vehicle. The electrical junction box 1 may also be called a junction box, fuse box, relay box, etc., but in this embodiment, these are collectively referred to as an electrical junction box.

[0013] The electrical junction box 1 of this embodiment has a configuration in which the connector C can be properly fitted by providing a connector support structure 400 capable of supporting the connector C on an assembly wall 121 to which the connector C is assembled and on an opposing wall 122 positioned opposite the assembly wall 121. The configuration of the electrical junction box 1 will be described in detail below with reference to Figs. 1 to 5.

[0014] In the following description, the three intersecting directions are referred to as the "depth direction X," "width direction Y," and "height direction Z" for convenience. The depth direction X, width direction Y, and height direction Z are perpendicular to each other. The depth direction X and width direction Y typically correspond to horizontal directions. The height direction Z typically corresponds to the vertical direction, and corresponds to the opening direction of the opening 13 of the housing body 10, the direction in which a mating connector is mated with a connector C assembled to the assembly wall portion 121 of the housing body 10 (hereinafter simply referred to as the "mating direction of the connector C"). In addition, the upper side in the vertical direction is referred to as the upper portion or upper side, and the lower side in the vertical direction is referred to as the lower portion or lower side. In the following description, the directions are described as directions in a state in which the components of the electrical junction box 1 are assembled, unless otherwise specified.

[0015] [Electrical junction box] First, a schematic configuration of the electrical junction box 1 will be described with reference to FIG. 1. The electrical junction box 1 is formed of an insulating resin material and includes a housing body 10, an upper cover 20 attached to the top of the housing body 10, and a lower cover 30 attached to the bottom of the housing body 10. The housing body 10 here is a member that constitutes the main body of the electrical junction box 1 and is also referred to as a frame. The upper cover 20 is a lid-like member that closes an upper opening 13 of the housing body 10 and is also referred to as an upper cover. The lower cover is a lid-like member that closes a lower opening (not shown) of the housing body 10 and is also referred to as a lower cover. Furthermore, the housing body 10 is open at the top and bottom in the height direction Z, and is surrounded all around, including the depth direction X and the width direction Y, by an outer wall portion 11 of the housing body 10, forming a substantially rectangular cylindrical shape. Therefore, the space inside the outer wall portion 11 of the housing body 10 forms part of the storage space of the electrical junction box 1. The upper cover and the lower cover are fitted to the housing body 10 and assembled via various locking mechanisms. Therefore, the upper cover 20 and the lower cover 30 form part of the storage space of the electrical junction box 1 through the space located inside them.

[0016] Next, the configuration of the housing body 10 in this embodiment will be described with reference to Figures 2 to 4. As shown in Figure 2, the housing body 10 includes an assembly wall 121 to which a connector C can be assembled, an opposing wall 122 positioned opposite the assembly wall 121, and a connector support structure 400 provided on the assembly wall 121 and the opposing wall 122.

[0017] [Assembly wall, opposing wall] The mounting wall 121 and the opposing wall 122 are parts of the inner wall 12 that is molded integrally with the outer wall 11 of the housing body 10. The inner wall 12 here divides the space located inside the outer wall 11 into multiple spaces in the depth direction X and width direction Y when the housing body 10 is viewed from the opening direction of the opening 13 (height direction Z), and the inner wall 12 includes the mounting wall 121, the opposing wall 122, and partition walls 123 and 124, as shown in Fig. 2. In the electrical junction box 1 of this embodiment, blocks (not shown) with electronic components assembled thereto and connectors C are housed in the individual spaces divided by the inner wall 12.

[0018] 2, the mounting wall 121 is formed in a plate shape that extends in the width direction Y and the height direction Z, and whose thickness direction is in the depth direction X. Therefore, the mounting wall 121 can partition a space located inside the outer wall 11 in the width direction Y.

[0019] 2, the mounting wall portion 121 extends from the outer wall portion 11 extending along the width direction Y to a pair of partition wall portions 123 protruding in the depth direction X. Both ends of the mounting wall portion 121 in the width direction Y are connected to the partition wall portions 123, respectively. Therefore, the mounting wall portion 121 of this embodiment is provided at a position spaced a certain distance in the depth direction X from the outer wall portion 11 extending along the width direction Y.

[0020] 2, the opposing wall portion 122 is formed in a plate shape that extends in the width direction Y and the height direction Z and has a plate thickness direction in the depth direction X. Therefore, similar to the mounting wall portion 121, the opposing wall portion 122 partitions a space located inside the outer wall portion 11 in the width direction Y. Furthermore, the opposing wall portion 122 is provided opposite to the inner surface 121a of the mounting wall portion 121 (the surface located opposite to the surface 121b that faces the outer wall portion 11). Therefore, the opposing wall portion 122 in this embodiment is positioned so as to sandwich the connector C mounted to the mounting wall portion 121.

[0021] 2, the opposing wall portion 122 protrudes in the width direction Y from the outer wall portion 11 extending along the depth direction X, and extends to the partition wall portion 124 located opposite the outer wall portion 11. Therefore, in the housing main body 10 of this embodiment, the connector C assembled to the assembly wall portion 121 can be accommodated in the space portion S partitioned by the outer wall portion 11, the assembly wall portion 121, the opposing wall portion 122, and the partition wall portion 124.

[0022] [Connector support structure] The connector support structure 400 supports the connector C assembled to the assembly wall portion 121, thereby preventing the connector C from shifting position. As shown in Figs. 2 to 4, the connector support structure 400 includes a fixing portion 410 that fixes the connector C to the assembly wall portion 121, and a rib 420 that comes into contact with the connector C assembled to the assembly wall portion 121.

[0023] The fixing portion 410 is a locking protrusion formed on the inner surface 121a of the mounting wall portion 121. The connector C to be mounted on the mounting wall portion 121 has a locking frame portion (not shown) on its side surface. Therefore, the fixing portion 410 of this embodiment can fix the connector C when it is inserted from the upper opening 13 (see FIG. 1) of the housing main body 10, by fitting the frame portion of the locking frame portion of the connector C with the claw-shaped protrusion portion of the locking protrusion.

[0024] The rib 420 is a protrusion formed on the inner surface 122a of the opposing wall 122. As shown in Fig. 2, the rib 420 extends in the depth direction X from the opposing wall 122 toward the assembly wall 121, and is formed in a plate shape with the width direction Y being the plate thickness direction. Furthermore, as shown in Fig. 2, the length of the rib 420 (length in the depth direction X) is set to a length that allows it to come into contact with the connector C. Therefore, the rib 420 of this embodiment can support the connector C by coming into contact with the connector C assembled to the assembly wall 121 via the fixing portion 410.

[0025] 2, the ribs 420 are provided in pairs spaced apart on both sides of the fixing portion 410 in the width direction Y, which is the extension direction of the opposing wall portion 122 and a direction intersecting the height direction Z, which is the fitting direction of the connector C assembled to the assembly wall portion 121, with the position of the fixing portion 410 as a reference. The ribs 420 are disposed opposite the fixing portion 410 and diagonally opposite the fixing portion 410. Therefore, the connector support structure 400 of this embodiment can support the connector C assembled to the assembly wall portion 121 by fixing the vicinity of the center of the connector C with the fixing portion 410 and supporting both ends of the connector C with the pair of ribs 420.

[0026] More specifically, the rib 420 of this embodiment is provided at the lower end of the opposing wall portion 122, as shown in Fig. 3. The rib 420 is provided below the fixing portion 410 (i.e., on the opposite side of the opening 13 of the housing main body 10, and on the inner side in the fitting direction of the connector C). As shown in Figs. 3 and 4, the rib 420 is configured to include a support portion 421 protruding from the inner surface 122a of the opposing wall portion 122 and a hook portion 422 protruding from a tip 421e of the support portion 421, and is formed into an L-shape as a whole.

[0027] The support portion 421 is located below the connector C assembled to the assembly wall portion 121, and when viewed from the height direction Z, the tip 421e side is positioned so as to overlap the connector C. As shown in Fig. 4, the support portion 421 of this embodiment is configured to include an abutment portion 421a and a reinforcing portion 421b, and is formed into a substantially rectangular shape when viewed from the width direction Y, which is the plate thickness direction.

[0028] The contact portion 421a is a portion that contacts the connector C assembled to the assembly wall portion 121. The contact portion 421a in this embodiment is an upper end surface of the support portion 421, and this end surface is formed linearly along the depth direction X. Therefore, when viewed from the height direction Z, the tip 421e side of the support portion 421 in this embodiment is positioned so as to overlap the connector C, and the contact portion 421a provided on the tip 421e side can contact the connector C by being brought into contact with the lower surface Cm of the connector C. Furthermore, the support portion 421 can support the connector C by contacting the connector C via the contact portion 421a.

[0029] The reinforcement portion 421b is a portion that reinforces the root portion (base end) of the support portion 421. In this embodiment, the reinforcement portion 421b is an upper corner formed between the opposing wall portion 122, and this corner is formed in a curved shape and recessed inward. Therefore, in the support portion 421 of this embodiment, when an external force is applied to the connector C assembled to the assembly wall portion 121 and the external force is transmitted to the abutment portion 421a via the connector C, stress concentration at the root portion can be suppressed.

[0030] The hook portion 422 is a portion that protrudes from the tip 421e of the support portion 421 toward the connector C along the fitting direction (height direction Z) of the connector C assembled to the assembly wall portion 121, and is inserted into the lower surface Cm of the connector C, thereby being disposed inside the connector C. As shown in Fig. 4, the hook portion 422 of this embodiment is configured to include an abutment portion 422a and guiding portions 422b and 422c, and is formed into a substantially rectangular shape when viewed from the width direction Y, which is the plate thickness direction.

[0031] The abutment portion 422a is a portion that abuts against the connector C assembled to the assembly wall portion 121. In this embodiment, the abutment portion 422a is an end face on the left side (the opposing wall portion 122 side) of the hook portion 422, and this end face is formed linearly along the height direction Z. Therefore, the hook portion 422 in this embodiment can come into contact with the connector C by abutting the abutment portion 422a against the structural wall Cw of the connector C and being caught on the connector C. In addition, the abutment portion 422a can function as a stopper by coming into contact with the connector C.

[0032] The guide portions 422b and 422c are portions that guide the hook portion 422 into the interior of the connector C when the hook portion 422 is inserted from the bottom surface Cm of the connector C. In this embodiment, the guide portion 422b is a corner on the right side (the assembly wall 121 side) of the tip, and the guide portion 422c is a corner on the left side (the opposing wall 122 side) of the tip. The guide portions 422b and 422c are formed in a curved shape that bulges outward. Furthermore, the guide portion 422b is formed with a relatively large curvature, and the guide portion 422c is formed with a relatively small curvature. Therefore, when the hook portion 422 of this embodiment is inserted from the bottom surface Cm of the connector C, the hook portion 422 is guided into the interior of the connector C mainly by using the guide portion 422b on the assembly wall 121 side, thereby making it easier to hook the connector C onto the hook portion 422. Furthermore, by reducing the roundness of the guide portion 422c of the hook portion 422 on the opposing wall portion 122 side, the range of the contact portion 422a formed on the opposing wall portion 122 side can be sufficiently ensured.

[0033] Next, with reference to FIG. 5, the operation of the connector support structure 400 when a mating connector is fitted to the connector C assembled to the assembly wall portion 121 will be described.

[0034] When an external force F acting from the upper side (the opening 13 side) toward the lower side is applied to the connector C assembled to the assembly wall portion 121 during mating with a mating connector, the connector C tends to shift downward due to the external force F (see displacement D1 in FIG. 5). At the same time, the assembly wall portion 121 is pulled by the connector C fixed via the fixing portion 410, causing the lower end portion 121c to tilt outward (toward the outer wall portion 11), and at the same time, the upper end portion 121d to tend to tilt inward (toward the opposing wall portion 122) (see displacements D2 and D3 in FIG. 5).

[0035] At this time, the connector C abuts against the rib 420, and the support portion 421 receives the external force F transmitted from the connector C, thereby suppressing the occurrence of displacement D1. Furthermore, the rib 420 can suppress rotation of the connector C (see rotation R in FIG. 5 ) by having the connector C catch on the hook portion 422, and the hook portion 422 receives the force that causes the lower end portion 121c of the assembly wall portion 121 to fall outward (toward the outer wall portion 11) due to the external force F, thereby suppressing the occurrence of displacements D2 and D3. Therefore, the connector support structure 400 of this embodiment can suppress misalignment of the connector C when a mating connector is mated with the connector C assembled to the assembly wall portion 121, thereby enabling the connector C to be mated properly.

[0036] The electrical connection box 1 described above comprises an assembly wall 121 to which a connector C can be assembled, an opposing wall 122 positioned opposite the assembly wall 121 and sandwiching the connector C assembled to the assembly wall 121, and a connector support structure 400 provided on the assembly wall 121 and the opposing wall 122, and the connector support structure 400 has a fixing portion 410 formed on the assembly wall 121 for fixing the connector C assembled to the assembly wall 121, and a rib 420 extending from the opposing wall 122 toward the assembly wall 121 and abutting the connector C assembled to the assembly wall 121.

[0037] According to this configuration, the connector support structure 400 applied to the electrical junction box 1 can properly support the connector C fixed to the assembly wall portion 121 via the fixing portion 410 by supporting the connector C with the ribs 420. Therefore, when a mating connector is mated with the connector C assembled to the assembly wall portion 121, the connector support structure 400 can prevent the connector C from being displaced due to twisting or bending of the assembly wall portion 121. Therefore, by providing the connector support structure 400 on the assembly wall portion 121 and the opposing wall portion 122, the electrical junction box 1 can properly mate the connector C, thereby improving the efficiency of the connector mating process.

[0038] Furthermore, the ribs 420 of the connector support structure 400 described above are provided in pairs on both sides of the fixing portion 410 at a distance from each other in a direction (width direction Y) intersecting the mating direction (height direction Z) of the connector C. With this configuration, the connector support structure 400 can more appropriately support the connector C assembled to the assembly wall portion 121 by fixing the connector C near the center in the width direction Y with the fixing portion 410 and supporting both ends of the connector C in the width direction Y with the pair of ribs 420. Therefore, the connector support structure 400 can more reliably prevent the connector C from shifting position when a mating connector is mated with the connector C assembled to the assembly wall portion 121, thereby enabling the electrical junction box 1 to more appropriately mate the connector C.

[0039] Furthermore, the rib 420 of the connector support structure 400 described above has a support portion 421 that extends toward the assembly wall portion 121 and is positioned so as to overlap the connector C assembled to the assembly wall portion 121 when viewed from the fitting direction of the connector C (height direction Z), thereby coming into contact with the connector C. With this configuration, the connector support structure 400 can support the connector C assembled to the assembly wall portion 121 by positioning the tip 421e of the support portion 421 so as to overlap the connector C. Therefore, the connector support structure 400 can prevent the connector C from being misaligned in the vertical direction (height direction Z) when a mating connector is mated with the connector C assembled to the assembly wall portion 121, thereby enabling the electrical junction box 1 to properly fit the connector C.

[0040] Furthermore, the rib 420 of the connector support structure 400 described above further has a hook portion 422 that protrudes from the tip 421e of the support portion 421 toward the connector C along the mating direction (height direction Z) of the connector C and hooks onto the connector C assembled to the assembly wall portion 121, thereby making contact with the connector C. With this configuration, the connector support structure 400 can more appropriately support the connector C assembled to the assembly wall portion 121 by the hook portion 422 provided on the tip 421e of the support portion 421 hooking onto the connector C. Therefore, the connector support structure 400 can more reliably prevent the position of the connector C from shifting in the lateral direction (depth direction X) when a mating connector is mated with the connector C assembled to the assembly wall portion 121, thereby enabling the electrical junction box 1 to properly mate the connector C.

[0041] [Second embodiment] Next, an electric junction box 1A according to a second embodiment shown in Figures 6 to 8 will be described. The electric junction box 1A differs from the electric junction box 1 in the configuration of the rib 420. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

[0042] Specifically, the electrical junction box 1A differs from the electrical junction box 1 in that the rib 420A of the connector support structure 400A is composed of only a support portion 421.

[0043] As shown in FIG. 6, the rib 420A is provided on the housing main body 10A, and is formed in a plate shape with the width direction Y being the plate thickness direction. As shown in FIG. 7, the rib 420A is provided at the lower end of the opposing wall portion 122. The rib 420A is provided below the fixing portion 410 (i.e., on the opposite side of the opening 13 of the housing main body 10, and on the inner side in the fitting direction of the connector C). The support portion 421 is located below the connector C assembled to the assembly wall portion 121, and a tip 421e side of the support portion 421 is positioned so as to overlap the connector C when viewed from the height direction Z. As shown in FIG. 7, the support portion 421 includes an abutting portion 421a and a reinforcing portion 421b, and is formed in a substantially rectangular shape when viewed from the width direction Y, which is the plate thickness direction. Therefore, like the rib 420 described above, the rib 420A can support the connector C by abutting the abutment portion 421a provided on the tip 421e side of the support portion 421 against the underside Cm of the connector C.

[0044] As shown in FIG. 8, the rib 420A abuts against the connector C, and the support portion 421 receives the external force F transmitted from the connector C, thereby suppressing the occurrence of displacement D1. Furthermore, by suppressing the occurrence of displacement D1, the rib 420A can suppress rotation of the connector C (see rotation R in FIG. 8), thereby suppressing the occurrence of displacements D2 and D3. Therefore, with this configuration, the connector support structure 400A, like the connector support structure 400 described above, can support the connector C assembled to the assembly wall portion 121 by positioning the tip 421e of the support portion 421 so as to partially overlap with the connector C. Furthermore, the connector support structure 400A can suppress displacements D1 to D3 when a mating connector is mated with the connector C assembled to the assembly wall portion 121, thereby suppressing misalignment of the connector C. Therefore, the electrical junction box 1A, like the electrical junction box 1 described above, can properly mate the connector C.

[0045] [Third embodiment] Next, an electric junction box 1B according to a third embodiment shown in Figures 9 to 11 will be described. The electric junction box 1B differs from the electric junction boxes 1 and 1A in the configuration of the rib 420. In the third embodiment, the same components as those in the first and second embodiments are denoted by the same reference numerals, and detailed description thereof will be omitted.

[0046] Specifically, the electrical junction box 1B differs from the electrical junction boxes 1 and 1A in that the rib 420B of the connector support structure 400B is composed only of a support portion 421B, and the length of the support portion 421B and its position relative to the opposing wall portion 122 are different.

[0047] As shown in Fig. 9, the rib 420B is provided on the housing main body 10B, and is formed in a plate shape with the width direction Y being the plate thickness direction. As shown in Fig. 10, the rib 420B is provided on the upper end of the opposing wall portion 122, and is provided above the fixing portion 410 (i.e., on the opening 13 side of the housing main body 10, and on the front side in the fitting direction of the connector C). The rib 420B is formed only by a support portion 421B different from the support portion 421, and the support portion 421B is located to the side (on the left side in Fig. 10) of the connector C assembled to the assembly wall portion 121. The support portion 421B is configured to include an abutting portion 421aB different from the abutting portion 421a, and is formed in a substantially rectangular shape when viewed from the width direction Y, which is the plate thickness direction. The contact portion 421aB is an end face (i.e., a tip 421eB of the support portion 421B) on the right side (the assembly wall portion 121 side) of the support portion 421B, and this end face is formed linearly along the height direction Z. Therefore, the support portion 421B of this embodiment can contact the connector C by bringing the contact portion 421aB into contact with the side surface Cn of the connector C and sandwiching the connector C between the support portion 421B and the assembly wall portion 121. Furthermore, the rib 420B can support the support portion 421B by contacting the connector C via the contact portion 421aB.

[0048] 11, the rib 420B abuts against the connector C, thereby suppressing rotation of the connector C (see rotation R in FIG. 11), thereby suppressing the occurrence of displacements D2 and D3. Therefore, with this configuration, the connector support structure 400B can support the connector C assembled to the assembly wall 121 by having the tip 421eB of the support portion 421B in contact with the connector C. Furthermore, the connector support structure 400B can suppress displacements D2 and D3 when a mating connector is mated with the connector C assembled to the assembly wall 121, thereby suppressing misalignment of the connector C. Therefore, the electrical junction box 1B can properly mate the connector C, similar to the electrical junction boxes 1 and 1A described above.

[0049] The electrical junction boxes 1, 1A, and 1B according to the above-described embodiments of the present invention are not limited to the above-described embodiments, and various modifications are possible within the scope of the claims.

[0050] For example, there is no particular limitation on the number of ribs 420, 420A, and 420B, and there is no particular limitation on the positions at which ribs 420, 420A, and 420B are provided.
