Description

[Technical Field]

[0001] The present invention relates to a fixed body mounting structure that is attached to a fixed member with, for example, a bolt, and an electric junction box that is equipped with the fixed body mounting structure. [Background technology]

[0002] An electrical junction box installed in a vehicle generally comprises a junction box body that houses electronic components such as circuit boards, fuses, and relays, and a cover member that covers the opening of the junction box body, and is electrically connected to the electrical equipment in the vehicle.

[0003] As disclosed in Patent Document 1, for example, this electrical junction box is provided with fixing legs extending from the side of the junction box body, whose opening is covered by a cover member, toward the fixed member, such as a panel of the vehicle body, and the electrical junction box can be fixed to the fixed member by bolting the fixing legs to the fixed member.

[0004] Such electrical junction boxes are connected to electronic devices and other components mounted on the vehicle via wire harnesses and are often mounted in a recessed location in the engine compartment. For this reason, when driving in the rain, for example, rainwater entering the engine compartment may splash onto the electrical junction box and unintentionally trickle down the fixing legs, potentially causing problems with the bolt holes. Therefore, it was necessary to prevent liquids such as rainwater from entering the bolt holes. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-153934 Summary of the Invention [Problem to be solved by the invention]

[0006] In view of the above-mentioned problems, the present invention aims to provide a fixed body mounting structure and an electrical junction box that can prevent liquid from entering the bolt holes in the fixing legs that are bolted to the vehicle body. [Means for solving the problem]

[0007] The present invention provides a fixed body mounting structure for mounting a fixed body to a fixed member with a bolt, the fixed body comprising: a fixed main body portion; When the fixing body and the fixed member are attached to each other, the fixing body is disposed below the fixing body. Towards the fixed member From the fixed main body The fixing leg portion is inclined with respect to the mounting surface of the fixed member to which the fixing main body portion is attached, and a bolt mounting portion for mounting the bolt is provided at the tip end side thereof, and the bolt mounting portion is disposed between a hole forming portion that forms a bolt hole penetrating in a direction perpendicular to the mounting surface, and an inclined surface of the inclined fixing leg portion and an outer edge of the hole forming portion. and surrounding the periphery of the hole forming portion. The peripheral wall portion in the orthogonal direction and the peripheral wall portion on the inclined surface along the outer edge a protruding portion that protrudes from the peripheral wall portion, and the protruding portion surrounds the area where the peripheral wall portion is provided. and extends to the outer side edge of the fixed leg. It is characterized by:

[0008] The present invention is also characterized in that it is an electrical connection box that is equipped with the above-mentioned fixed body mounting structure and the fixed main body portion, and that has an insertion port through which an electric wire is inserted on a surface of the box-shaped fixed main body portion that is different from the surface on which the fixed body mounting structure is attached.

[0009] The protrusion may be provided in any location as long as it can change the flow direction of liquids such as water flowing down the inclined surface and prevent the liquid from entering the hole formation portion, including, for example, a location where it protrudes from a position spaced a predetermined distance from the peripheral wall portion or from an end portion of the peripheral wall portion. The liquid in the above description includes, for example, a viscous gel-like substance.

[0010] According to this invention, it is possible to prevent liquid from entering the bolt holes in the fixing legs that are fixed to the vehicle body with bolts. For example, when liquid flows along the inclined surface toward the bolt hole, the flow of the liquid can be diverted along the protrusion formed to surround the area where the peripheral wall is provided. By diverting the flow of liquid flowing along the inclined surface with the protrusion in this way, the liquid can be prevented from flowing into the hole formation section and from entering the bolt hole.

[0011] As an aspect of the present invention, the protrusion may be formed along the inclined surface on the upstream side of the peripheral wall in the inclination direction so as to surround the end of the peripheral wall. According to this invention, the liquid flowing from the upstream side of the inclined surface can be made to flow along the protrusion formed around the end of the peripheral wall, thereby redirecting the flow of the liquid in a direction different from the direction toward the hole formation portion, and preventing the liquid from flowing toward the hole formation portion.

[0012] In another aspect of the present invention, the peripheral wall portion may be open at the tip end side of the hole forming portion. This invention makes it possible to form a space at the tip side of the hole forming section, so that a bolt can be easily attached to the hole forming section, and even if liquid flowing along the inclined surface enters the hole forming section, the liquid can be drained from the open tip side without remaining in the hole forming section.

[0013] As another aspect of the present invention, the peripheral wall portion may be formed in a range surrounding the bolt hole to the tip side. With this invention, the protrusion formed to surround the area where the peripheral wall portion is provided can guide liquid flowing down the inclined surface to the tip side of the bolt hole, thereby more reliably preventing liquid from entering the bolt hole.

[0014] As another aspect of the present invention, the hole forming portion may have a flat surface parallel to the mounting surface. With this invention, the bolts can be oriented perpendicular to the mounting surface, so the fixing legs can be reliably fixed to the mounting surface, and even if liquid does enter the hole formation portion, the liquid can be prevented from remaining in the hole formation portion. Furthermore, if the mounting surface is inclined, the liquid that has entered the hole formation portion can be made to flow in the direction of the inclination, so even if liquid does enter the hole formation portion, it can be drained.

[0015] As another aspect of the present invention, a rib extending in the perpendicular direction may be provided on the rear surface of the hole forming portion, and the rib may form an imaginary flat surface parallel to the mounting surface. This invention improves the strength of the hole formation portion and allows the rear surface of the hole formation portion to abut against the mounting surface. This reduces wobble of the fixing leg relative to the mounting surface and stabilizes the fixing state of the fixing leg. This allows the fixing leg to be fixed to the object in a desired fixing state, preventing liquid from intentionally entering the hole formation portion.

[0016] As another aspect of the present invention, a drain hole penetrating in the perpendicular direction may be provided near the end of the inclined surface on the side of the fixed main body portion. According to this invention, liquid that runs down the side of the fixed body can be drained through the drainage holes to the back side of the fixed leg, reducing the amount of liquid that runs down the inclined surface and more reliably preventing liquid from entering the bolt hole.

[0017] In another aspect of the present invention, the fixed main body portion is approximately box-shaped when viewed from the orthogonal direction and has two pairs of opposing side walls, and the fixed leg portion may be arranged on one of the pair of opposing side walls and formed along one of the other opposing side walls. According to this invention, the fixing legs do not extend outward from the other opposing side walls of the fixing main body, so that the fixing body can be made compact.

[0018] As another aspect of the present invention, the fixing leg portion may be shaped like a substantially right-angled triangle having a side along one of the other opposing side walls when viewed from the orthogonal direction. According to this invention, when an unintended external force acts on the fixed main body, the external force can be distributed between one side wall and the other side wall, thereby improving the durability of the fixed leg. [Effects of the Invention]

[0019] The present invention can provide a fixed body mounting structure and an electrical junction box that can prevent liquid from entering the bolt holes in the fixing legs that are bolted to the vehicle body. [Brief explanation of the drawings]

[0021] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. The electrical junction box 10 of this embodiment includes a fixed main body 20 and fixed leg portions 30, and is disposed, for example, in the engine room of a vehicle. A fixed body mounting structure 1 for mounting such an electrical junction box 10 to a panel P in the engine room, which is a fixed body, with bolts X will be described with reference to Figs. 1 to 7.

Fig. 4 shows a partial cross-sectional view of the electrical junction box 10, and Figs. 5 and 6 show enlarged cross-sectional views of the bolt mounting portion 32 provided on the tip side Lf of the fixed leg 30. Fig. 7 shows an enlarged plan view of the fixed leg 30, illustrating the flow of the liquid R relative to the fixed leg 30.

[0024] For convenience, the longitudinal direction of the electrical junction box 10 in Fig. 1 is referred to as the longitudinal direction L, the short side direction of the electrical junction box 10 is referred to as the width direction W, and the up-down direction in Fig. 1 is referred to as the height direction H. In Fig. 1, the left side along the longitudinal direction L is referred to as the tip side Lf, and the right side along the longitudinal direction L is referred to as the base side Lb, the direction in which the cover member 22 is arranged relative to the junction box main body 21 is referred to as the upward direction, and the direction in which the junction box main body 21 is arranged relative to the cover member 22 is referred to as the downward direction. Note that the longitudinal direction L, width direction W, and height direction H are perpendicular to one another. This direction is the same in FIGS.

[0025] The fixed body mounting structure 1 is a structure in which the fixing legs 30 of the electrical junction box 10 are fixed to a panel P, which is a fixed member, with bolts X, and the electrical junction box 10 is mounted to the panel P with the bolts. The electrical junction box 10 includes a fixed main body 20 that houses electronic components such as circuit boards, fuses, and relays, fixed legs 30 that extend from the fixed main body 20 toward a first fixed portion P1 on the panel P, and second fixed legs 40 that extend from the fixed main body 20 toward a second fixed portion P2 on the panel P. The electronic components housed inside the fixed main body 20 are connected to the electrical equipment mounted on the vehicle via electric wires WH.

[0026] As shown in Figures 1 and 2, the fixed main body portion 20 is provided with a connection box main body 21 and a cover member 22 that covers the opening of the connection box main body 21, and is provided with a fixing portion 23 that engages and fixes the connection box main body 21 and the cover member 22.

[0027] The connection box main body 21 is composed of a bottom 211 that forms the bottom surface of the fixed main body portion 20, first side surfaces 212, 212 that stand upright along the longitudinal direction L, and second side surfaces 213, 213 that stand upright along the width direction W.

[0028] 1 and 2, the first side surfaces 212 are erected from both ends of the connection box main body 21 in the width direction W. An insertion hole 24 is provided on one side of the first side surfaces 212 between the opposing first side surfaces 212, 212, through which electric wires WH electrically connected to electronic components housed inside the fixed main body 20 are inserted to be drawn out to the outside of the fixed main body 20.

[0029] 1 and 2, the second side surfaces 213 are erected from both ends of the connection box body 21 in the longitudinal direction L. One side of the opposing second side surfaces 213 (the second side surface 213 on the tip end side Lf) is provided with a fixing leg 30 extending toward the first fixed portion P1. Meanwhile, the other side of the second side surface 213 (the second side surface 213 on the base end side Lb) is provided with a second fixing leg 40 extending toward the second fixed portion P2.

[0030] 1 to 3, the fixing leg 30 is disposed on the second side surface 213 of the tip side Lf, and is formed along one side of the first side surface 212, and is configured to extend downward as it moves from the fixing main body 20 toward the tip side Lf. In addition, in a plan view, the side along one side of the first side surface 212 has a substantially right-angled triangular shape along the longitudinal direction L.

[0031] In other words, the fixing leg 30 is configured to extend downward from the second side surface 213 and taper as it moves toward the tip side Lf, and when attached to the panel P, it is inclined with respect to the attachment surface M of the panel P.

[0032] The fixing leg 30 configured in this manner is composed of an inclined portion 31 that slopes downward as it approaches the tip side Lf, and a bolt mounting portion 32 that mounts a bolt X on the tip side Lf of the inclined surface 31a to fix it to the panel P, as shown in Figures 2 to 4.

[0033] 2 to 4, the outer side of the inclined portion 31 in the width direction W follows the first side surface 212 and extends downward from the second side surface 213. The upper surface of the inclined portion 31 is a flat inclined surface 31a.

[0034] In addition, near the connection point of the inclined portion 31 with the fixed main body portion 20, i.e., near the end of the base end side Lb of the inclined portion 31, a drain hole 33 is provided that penetrates the fixed leg portion 30 in the height direction H (see Figure 4).

[0035] As shown in Figures 3 to 6, the bolt mounting portion 32 provided on the tip side Lf of the inclined portion 31 is provided with a hole forming portion 51 for attaching the bolt X, a peripheral wall portion 52 surrounding the periphery of the hole forming portion 51, and a protruding portion 53 protruding above the inclined surface 31a.

[0036] The hole forming portion 51 is the portion where the fixing leg portion 30 is fixed to the first fixed portion P1, and as shown in Figure 3, is formed in a circular shape when viewed from above, and a first bolt hole 511 that penetrates in the height direction H is formed in the approximate center when viewed from above.

[0037] 5, flat surface 51a, which is the upper surface of hole forming portion 51, is configured to be parallel to mounting surface M when fixing leg 30 is fixed to panel P. In addition, as shown in FIG. 6, a plurality of ribs 512 extending along height direction H are provided on the bottom surface of hole forming portion 51 radially from first bolt hole 511 as the center.

[0038] The height of this rib 512 is adjusted so that it is parallel to the mounting surface M when the fixing leg 30 is fixed to the panel P. As a result, a fixed bottom surface 51b that is parallel to the mounting surface M is formed on the back side of the hole forming portion 51 (see FIG. 6). That is, the first bolt hole 511 is perpendicular to the mounting surface M of the panel P when the fixing leg 30 is fixed to the panel P.

[0039] The peripheral wall portion 52 is a wall surface erected along the height direction H, and is disposed between the outer edge of the upstream side (base end side Lb) of the hole forming portion 51 and the inclined surface 31a. 3 to 6, the peripheral wall portion 52 is configured to have a circular shape in plan view on the upstream side (base end side Lb) of the hole forming portion 51, and is provided upright along the outer periphery of the hole forming portion 51. The peripheral wall portion 52, which is configured to have a circular shape in plan view, decreases in height toward the tip side Lf, and has an opening on the tip side Lf of the peripheral wall portion 52. That is, the peripheral wall portion 52 is formed in an arc shape with an open tip side Lf in plan view.

[0040] The tip side Lf of the peripheral wall portion 52 is configured to be at the same position as the tip of the first bolt hole 511 in a side view, and surrounds the tip side Lf of the first bolt hole 511. In other words, the center of the first bolt hole 511 is located on the base end side Lb of the straight line connecting the tip sides Lf of the peripheral wall portion 52 in a plan view.

[0041] As shown in FIGS. 3 to 6, the protrusion 53 is disposed on the inclined surface 31a outside the peripheral wall 52, and protrudes upward from the inclined surface 31a by a predetermined length. More specifically, the protruding portion 53 protrudes upward by a predetermined length from the upper end of the peripheral wall portion 52 along the peripheral wall portion 52 so as to surround the end portion of the peripheral wall portion 52, which is formed in an arc shape in a plan view. Like the peripheral wall portion 52, the protruding portion 53 has an opening on the tip side Lf.

[0042] That is, the protrusion 53 protrudes upward from the end of the peripheral wall 52 so as to be flush with the peripheral wall 52 along the height direction H, and is formed in an arc shape having an opening on the tip side Lf in a plan view. The tip side Lf of the protrusion 53 is configured to be in the same position as the tip of the first bolt hole 511 in a side view. Therefore, the protrusion 53 is formed so as to surround the upstream side (base side Lb) of the range in which the peripheral wall 52 is provided. The connecting portion between the base end side Lb of the protruding portion 53 and the inclined portion 31 is formed in an arc shape (see FIGS. 5 and 6).

[0043] The second fixing leg 40 extends downward from the other side of the second side surface 213, and at its tip is provided a second hole forming portion 41 having a second bolt hole 42 formed therein through which a bolt X can be inserted.

[0044] The second fixing leg 40 configured in this manner can be fixed to the panel P by positioning the second hole forming portion 41 at the second fixed portion P2 and inserting a bolt X through the second bolt hole 42, while fixing the second fixing leg 40 to the panel P, with the electrical connection box 10 fixed to the panel P.

[0045] The electrical connection box 10 configured in this manner has the bolt mounting portion 32 positioned relative to the first fixed portion P1 on the panel P, and the fixed bottom surface 51b attached to the mounting surface M, with the bolt X inserted into the first bolt hole 511, so that the fixed leg portion 30 can be bolted to the panel P.

[0046] Similarly, the second hole forming portion 41 can be disposed relative to the second fixed portion P2 of the panel P, and the bolt X can be inserted into the second bolt hole 42 to bolt the second fixing leg portion 40 to P. This allows the electrical junction box 10 to be fixed to the panel P.

[0047] As a result, the fixing leg 30 is inclined with respect to the mounting surface M (see FIG. 2). Therefore, if liquid R such as rainwater gets on the electrical junction box 10, the liquid R will flow downward along the first side surface 212 and the second side surface 213.

[0048] Of this, part of the liquid R running down the second side surface 213 on the tip side Lf is drained to the lower side of the electrical junction box 10 through the drainage holes 33 penetrating in the height direction H. In addition, part of the liquid R running down the second side surface 213 runs down the inclined surface 31a of the fixing leg 30 and flows to the tip side Lf, as shown in FIG.

[0049] In this case, the liquid R flowing to the tip side Lf is blocked by the protrusion 53 erected from the upper end of the peripheral wall portion 52, and flows to the tip side Lf along the protrusion 53, which is formed in an arc shape when viewed in a plane.

[0050] Furthermore, since the tip side Lf of the peripheral wall portion 52 and the protruding portion 53 is configured to be at the same position as the tip (tip side Lf) of the first bolt hole 511 in a side view, it is possible to prevent the liquid R that has flowed along the protruding portion 53 to the tip side Lf from entering the hole forming portion 51. This makes it possible to prevent the liquid R from entering the first bolt hole 511.

[0051] As described above, the fixed body mounting structure 1 is a structure in which an electrical junction box 10 is mounted to a panel P with a bolt X. The electrical junction box 10 includes a fixed main body 20 and a fixed leg 30 extending from the fixed main body 20 toward the panel P. The fixed leg 30 is inclined with respect to the mounting surface M of the panel P to which the fixed main body 20 is mounted, and is provided with a bolt mounting portion 32 on its distal end Lf for mounting a bolt X. The bolt mounting portion 32 includes a hole forming portion 51 that forms a first bolt hole 511 penetrating in a height direction H perpendicular to the mounting surface M, a peripheral wall portion 52 in the height direction H that is disposed between an inclined surface 31 a of the inclined fixed leg 30 and the outer edge of the hole forming portion 51, and a protruding portion 53 that is disposed on the inclined surface 31 a outside the peripheral wall portion 52 and protrudes from the inclined surface 31 a. The protruding portion 53 is formed to surround the area in which the peripheral wall portion 52 is provided.

[0052] In addition, the electrical connection box 10 is provided with a fixed leg portion 30 and a fixed main body portion 20, and an insertion hole 24 through which the electric wire WH is inserted is provided on a first side surface 212 of the box-shaped fixed main body portion 20, which is a side surface different from the second side surface 213 to which the fixed leg portion 30 is attached.

[0053] 7, when liquid R flows along inclined surface 31a toward first bolt hole 511, the flow of liquid R can be diverted along protrusion 53 formed to surround the area where peripheral wall portion 52 is provided. By diverting the flow of liquid R flowing along inclined surface 31a with protrusion 53 in this way, liquid R can be prevented from flowing into hole forming portion 51 and from entering first bolt hole 511. Therefore, liquid R can be prevented from entering first bolt hole 511 in fixing leg 30 that is fixed to the vehicle body with a bolt.

[0054] Furthermore, the protrusion 53 is formed along the inclined surface 31a on the upstream side (base end side Lb) of the peripheral wall 52 in the inclination direction so as to surround the end of the peripheral wall 52. This allows the liquid R flowing from the upstream side of the inclined surface 31a to flow along the protrusion 53 formed to surround the end of the peripheral wall 52. This therefore changes the flow of the liquid R to a direction different from the direction toward the hole formation portion 51, making it possible to more reliably prevent the liquid R from flowing toward the hole formation portion 51.

[0055] Furthermore, since the peripheral wall portion 52 is open on the tip side Lf of the hole forming portion 51, a space can be formed on the tip side Lf of the hole forming portion 51. This allows the bolt X to be easily attached to the hole forming portion 51.

[0056] Furthermore, even if the liquid R flowing along the inclined surface 31a enters the hole forming portion 51, the liquid R can be drained from the open tip side Lf without remaining in the hole forming portion 51. Therefore, it is possible to prevent the liquid R from entering the first bolt hole 511 in the fixing leg 30 that is fixed to the vehicle body with a bolt.

[0057] Furthermore, peripheral wall portion 52 is formed in a range that surrounds the area from first bolt hole 511 to tip side Lf. As a result, protrusion 53, which is formed so as to surround the area in which peripheral wall portion 52 is provided, can guide liquid R that has flowed down inclined surface 31a to tip side Lf of first bolt hole 511, making it possible to more reliably prevent liquid R from entering first bolt hole 511.

[0058] Furthermore, the hole forming portion 51 has a flat surface 51a that is parallel to the mounting surface M, and therefore the bolt X can be oriented perpendicular to the mounting surface M. This allows the fixing leg 30 to be reliably fixed to the mounting surface M, and even if the liquid R does enter the hole forming portion 51, the liquid R can be prevented from remaining in the hole forming portion 51.

[0059] Furthermore, if the mounting surface M is inclined, the liquid R that has entered the hole formation portion 51 can be made to flow in the direction of the inclination, so even if the liquid R does enter the hole formation portion 51, the liquid R can be discharged.

[0060] Furthermore, a rib 512 extending in the height direction H is provided on the back surface of the hole forming portion 51, and the rib 512 forms an imaginary flat surface (fixed bottom surface 51b) parallel to the mounting surface M. This improves the strength of the hole forming portion 51 and allows the back surface of the hole forming portion 51 and the mounting surface M to abut against each other.

[0061] This prevents the fixing leg 30 from wobbling relative to the mounting surface M and stabilizes the fixed state of the fixing leg 30, thereby achieving the desired fixed state and fixing the electrical connection box 10 to the panel P in a manner that intentionally prevents liquid R from entering the hole forming portion 51.

[0062] Furthermore, by providing drainage holes 33 penetrating in the height direction H near the end of inclined surface 31a on the side of fixed main body 20, liquid R running down the side of fixed main body 20 can be discharged from drainage holes 33 to the back side of fixed leg 30, thereby reducing the amount of liquid R running down inclined surface 31a. Therefore, liquid R can be more reliably prevented from entering first bolt hole 511.

[0063] Furthermore, the fixed main body 20 is generally box-shaped and has two pairs of opposing side walls (first side surfaces 212, 212 and second side surfaces 213, 213) when viewed from the height direction H. The fixed leg 30 is disposed on one of the pair of opposing second side surfaces 213, 213, and is formed along one of the other opposing first side surfaces 212, 212. This prevents the fixed leg 30 from extending outward from the first side surface 212 of the fixed main body 20, allowing the electrical junction box 10 to be made compact.

[0064] Furthermore, when viewed from the height direction H, the fixed leg portion 30 has a generally right-angled triangular shape having a side along one of the second side surfaces 213, 213. This allows the external force to be dispersed between one side wall and the other side wall when an unintended external force acts on the fixed main body portion 20, thereby improving the durability of the fixed leg portion 30.

[0066] For example, in this embodiment, the protruding portion 53 protrudes upward along the outer edge of the peripheral wall portion 52, but is not limited to this configuration and may protrude upward, for example, on the base end side Lb of the peripheral wall portion 52 (see FIG. 8(a)). Moreover, the protruding portion 53 is not limited to having an arc shape in a plan view and may have a triangular shape in a plan view (see FIG. 8(b)).
