Description

Electrical junction box

The present invention relates to an electrical junction box mounted on a vehicle, and more particularly to an electrical junction box having a drainage structure.

Conventionally, an electrical junction box mounted on a vehicle is configured to include a box body on which electrical components such as relays, fuses, and electric wires are mounted, and an upper cover and a lower cover that cover the upper and lower openings of the box body. The upper cover and the lower cover prevent water from splashing directly onto the box body.

By the way, the water adhering to the surface of the electrical junction box may enter the interior of the electrical junction box through the fitting gap between the box body, the upper cover, and the lower cover. Therefore, for example, as described in JP-A-9-308053 (Patent Document 1), a drain hole is provided in the bottom wall of the lower cover, and an inclined surface inclined downward toward the drain hole is provided in the bottom wall. There has been proposed an electrical junction box having a drainage structure that drains water that has entered the electrical junction box by flowing it down to a drainage hole.

However, the drainage structure described in Patent Document 1 is considered based on the assumption that the vehicle body itself does not tilt with respect to the ground plane as in the case of a four-wheeled vehicle. Currently, no measures have been taken for vehicles that run or stop in a state where the vehicle is tilted to the left or right.

Therefore, simply providing an inclined surface that inclines downward toward the drainage hole may not provide the expected drainage effect in a vehicle such as a motorcycle that often tilts the vehicle body itself to the left or right with respect to the ground contact surface. There was a risk of occurrence.

Japanese Patent Laid-Open No. 9-308053

The present invention has been made in the background of the above-described circumstances, and the solution is to provide a drainage structure that can provide an effective drainage effect even in a vehicle in which the vehicle body itself tilts left and right with respect to the ground plane. Another object is to provide an electrical junction box having a novel structure.

According to a first aspect of the present invention, there is provided an electrical junction box that is mounted on a vehicle and includes a box body on which electrical components are mounted and a lower cover that covers a lower opening of the box body. It has an inclined surface inclined downward from the upper end portion toward the other lower end portion, and drainage holes are provided at both end portions in the inclined direction of the inclined surface.

According to the electrical junction box having the structure according to the present invention, the bottom wall of the lower cover is provided with the inclined surfaces inclined downward from the upper end portion toward the other lower end portion, and both ends of the inclined surfaces. A drain hole is provided in the part. Therefore, in a non-tilt state where the vehicle body is not tilted with respect to the ground plane, water that has reached the bottom wall of the lower cover travels along the tilted surface that slopes downward and collects at the other lower end located at the lowermost end. It is drained and quickly drained from a drain hole provided at the other lower end.

Further, when the vehicle body is inclined with respect to the ground surface and the vehicle body is inclined toward the other lower end portion located at the lowermost end of the lower inclined surface, the inclination toward the other lower end portion is performed. The slope of the surface becomes steeper, and the water collecting effect toward the drain hole is more advantageously exhibited. Further, when the vehicle body is inclined with respect to the ground surface and the vehicle body is inclined toward one upper end portion located at the uppermost end of the lower inclined surface, the inclined surface faces one upper end portion. Therefore, water is collected at one upper end portion along the inclined surface, and can be quickly drained from a drain hole provided at one upper end portion.

In short, in the conventional structure, since the drain hole is provided only at the other lower end of the inclined surface, when the vehicle body is inclined in the opposite direction to the inclined surface inclined downward, one upper end of the inclined surface is provided. Although the water collected in the part was not drained and could reach the box body side, in this aspect, the drainage hole is also provided in one upper end part, so the vehicle body tilts downward Even when inclined in the direction opposite to the inclined surface, it is possible to realize quick drainage from the drainage hole.

Even in the case of a four-wheeled vehicle in which the vehicle body is not inclined with respect to the ground surface, depending on the inclination of the road surface, one upper end of the inclined surface may be located vertically below the other lower end. Although assumed, even in such a case, quick drainage can be promoted from the drainage hole at one upper end.

According to a second aspect of the present invention, there is provided the vehicle according to the first aspect, wherein the vehicle is parked with an inclination so that one of the left and right directions is lowered, and is lowered when parked. The vehicle is mounted on the vehicle so that the lower end portion is positioned at the bottom.

According to this aspect, when a motorcycle or the like is parked by the side stand so that the vehicle itself tilts so that one of the left and right directions is lowered, the lower end is positioned on one side that is lowered during parking. It is to be mounted on the vehicle. Thereby, at the time of parking, the inclination of the inclined surface of the lower cover bottom wall becomes steep, and the water collecting effect toward the drainage hole and the drainage effect from the drainage hole can be exhibited more advantageously.

According to a third aspect of the present invention, there is provided the vehicle according to the first aspect, wherein the vehicle is parked while being inclined so that one of the left and right directions is lowered, and is lowered when parked. And the upper end is mounted on the vehicle so that the upper end is positioned lower than the lower end when the vehicle is parked.

According to this aspect, when a motorcycle or the like is parked by the side stand so that the vehicle itself is inclined so that one of the left and right directions is lowered, the upper end is located on one side that is lowered during parking, and The vehicle is mounted on the vehicle such that the upper end portion is positioned below the lower end portion. Therefore, the inclination angle of the inclined surface at the time of parking is appropriately adjusted so as to promote drainage from the drainage hole provided at the upper end. In addition, it is possible to prevent a problem that the inclination angle of the inclined surface at the time of parking becomes too large as it is vertical, and the drainage from the drainage hole is hardly promoted.

A fourth aspect of the present invention is the one described in the third aspect, wherein an electric wire outlet hole is formed in a side wall at the lower end portion of the lower cover.

According to this aspect, the wire outlet hole is formed in the side wall on the lower end side of the inclined surface of the lower cover. When the vehicle is parked, the upper end portion of the inclined surface is positioned below the lower end portion, and can be quickly drained from the drain hole in the upper end portion. Therefore, it is possible to prevent the drainage from the electric wire outlet hole formed on the side wall on the lower end side or the drained water from traveling along the electric wire and causing a failure in the electric system.

According to the electrical junction box of the present invention, the bottom wall of the lower cover is provided with inclined surfaces that are inclined downward from one upper end to the other lower end, and drainage is provided at both ends of the inclined surface. A hole is provided. Therefore, even if the vehicle body tilts on either side of the tilt direction of the downward inclined surface, the vehicle is urged to drain quickly from drain holes provided at both ends of the inclined surface, and the vehicle body itself tilts with respect to the ground plane. Even if it is installed, effective drainage effect can be obtained stably.

The electrical junction box 10 is disposed at a proper position of a motorcycle (not shown) as a vehicle, and has a function of distributing power supplied from the battery to on-vehicle electrical components such as a motor and a lamp. The electrical junction box 10 is mounted on a motorcycle with the vertical direction in FIG. 1 as the vertical direction. FIG. 1 shows a state of the electric junction box 10 in a non-tilt state in which the motorcycle is not tilted to the left or right side with respect to the ground plane. Accordingly, the electrical junction box 10 is also inclined to the left and right sides in FIG. In the following description, unless otherwise specified, the vertical direction refers to the vertical direction in FIG. 1, and the horizontal direction refers to the horizontal direction in FIG.

More specifically, the electrical junction box 10 includes a box body 12, an upper cover 14 that covers the upper opening of the box body 12, and a lower cover 16 that covers the lower opening of the box body 12. The box body 12, the upper cover 14, and the lower cover 16 are all made of synthetic resin.

As shown in FIG. 3, the box body 12 as a whole has a long rectangular block shape. On the upper surface of the box body 12, a plurality of

relay mounting portions

18a and 18b (two in this embodiment) and a plurality of fuses are mounted. Portions 20 (six in this embodiment) are formed to open upward. As shown in FIG. 4, a plurality of terminal receiving holes 22 are formed in the lower surface of the box body 12 so as to open downward, and the crimp terminals 23 crimped to the ends of the electric wires 21 are received in the terminal receiving holes 22. It is arranged. Further, in the box body 12, a bus bar (not shown) that constitutes an internal circuit is accommodated in a bus bar accommodation groove (not shown). For the purpose of clarifying the drawings, the electric wires 21 and the crimp terminals 23 are shown by phantom lines only in FIG. 4 and are not shown in other drawings.

fitting portions

32 and 34 to be mounted on fixing brackets (not shown) are provided on the outer peripheral surfaces of the

peripheral walls

30a and 30c facing each other in the width direction of the box body 12 (vertical direction in FIG. 3). The electric connection box 10 is stably held at a predetermined position of the vehicle by fitting the

lock fitting portions

32 and 34 to a fixing bracket (not shown).

On the

peripheral walls

30b and 30d facing each other in the longitudinal direction of the box body 12 (left and right direction in FIG. 3), a U-shaped lock frame 36 is projected in the vicinity of the upper opening of the box body 12 in plan view. ing. Further, in the vicinity of the lower opening in the

peripheral walls

30b and 30d of the box body 12, two

lock protrusions

38 and 38 are provided so as to be spaced apart from each other in the circumferential direction.

The upper cover 14 has a bottomed box shape that opens downward (see FIG. 4), and is formed in a substantially rectangular shape that is substantially the same as the upper surface of the box body 12 in plan view (see FIG. 2). ). On the upper bottom portion 40 of the upper cover 14, presser protrusions 42 a and 42 b that protrude toward the

relays

relays

24a and 24b with a slight gap therebetween. As a result, when the

relays

24a and 24b are lifted due to vibration or the like during vehicle travel, the

relays

24a and 24b come into contact with the presser protrusions 42a and 42b, so that the

relays

24a and 24b come out of the

relay mounting portions

18a and 18b. Is to be prevented.

In addition, a spare fuse holding portion 43 is provided on the upper bottom portion 40 of the upper cover 14 at a position facing the fuse mounting portion 20 when assembled to the box body 12, and the spare fuse 26 is accommodated and held. .

On the

circumferential walls

44b and 44d facing in the longitudinal direction of the upper cover 14 (left and right direction in FIG. 2),

elastic lock pieces

46 and 46 are respectively disposed at positions facing the lock frame body 36 of the box body 12 and the

circumferential walls

44b and 44b. It protrudes in a cantilever shape with a gap between it and 44d. Locking

claw portions

48 and 48 projecting outward are provided at the projecting tip portions of the respective elastic lock pieces 46. Note that the outer surfaces of the

peripheral walls

44a and 44c facing each other in the width direction of the upper cover 14 (vertical direction in FIG. 2) are flat surfaces on which nothing protrudes.

When the upper cover 14 is assembled to the upper opening of the box body 12, as shown in FIG. 5, the inner peripheral surface of the peripheral wall 44 of the upper cover 14 is the outer periphery of the upper end portion of the peripheral wall 30 of the box body 12. It is inserted so as to overlap the surface. Further, when the upper cover 14 is pushed into the box body 12, the lock claw portions 48 of the

elastic lock pieces

46, 46 of the upper cover 14 are attached to the lock frame body 36 of the box body 12 as shown in FIG. 4. The

elastic lock pieces

46 and 46 are bent inward and deformed to allow further pushing. When the

lock claw portions

48 and 48 get over the

lock frame bodies

36 and 36 and the

elastic lock pieces

46 and 46 are elastically restored, each lock claw portion 48 engages with the lock frame body 36 and the upper cover 14. Is locked in a state of being attached to the upper opening of the box body 12.

Next, the lower cover 16 has a bottomed box shape that opens upward (see FIG. 4), and is formed in a substantially rectangular shape that is substantially the same as the lower surface of the box body 12 in plan view (see FIG. 4). 6). The outer surfaces of the

peripheral walls

50a and 50c facing each other in the width direction of the lower cover 16 (vertical direction in FIG. 6) are flat surfaces on which nothing projects. On the other hand, two elastic lock pieces are provided at positions facing the lock protrusions 38 of the box body 12 at the opening side end portions of the

peripheral walls

50b and 50d facing each other in the longitudinal direction of the lower cover 16 (left and right direction in FIG. 6). 52 and 52 project upwardly in a cantilever shape (see FIG. 7). Each elastic lock piece 52 has an inverted U shape and protrudes upward from the opening side end portions of the

peripheral walls

50 b and 50 d, and the engaging portion 54 provided at the protruding tip portion interferes with the lock protruding portion 38. As a result, the elastic lock piece 52 is bent and deformed toward the outer peripheral side, while the engagement portion 54 gets over the lock projection 38 and the elastic lock piece 52 is elastically restored, so that the engagement portion 54 is engaged with the lock projection 38. Thus, the lower cover 16 is locked in a mounted state in the lower opening of the box body 12.

The opening end surface 56 in the peripheral wall 50 of the lower cover 16 is overlapped with the outer peripheral water stop wall 58 that overlaps with the outer peripheral surface of the peripheral wall 30 of the box body 12 and the inner peripheral surface of the peripheral wall 30 of the box main body 12. The inner peripheral side water blocking walls 60 are distributed in the circumferential direction of the opening end surface 56. Specifically, on the opening end surface 56, in the left region of FIG. 6, an outer peripheral water stop wall 58 projects from the

peripheral walls

50a, 50b, 50c. On the other hand, in the region on the right side from the center portion of FIG. 6, an inner peripheral water stop wall 60 is provided so as to extend over the

peripheral walls

50c, 50d, 50a. In this way, by providing the outer peripheral side water stop wall 58 and the inner peripheral side water stop wall 60 dispersed in the circumferential direction, the timing when the lower cover 16 is attached to the lower opening of the box body 12 is set to the outer peripheral side water stop. It can be dispersed when the wall 58 is fitted and when the inner peripheral side water blocking wall 60 is fitted, and the fitting force required at one time can be reduced.

In FIG. 5, a state in which the inner peripheral side water blocking wall 60 provided on the opening end surface 56 of the lower cover 16 is overlapped with the inner peripheral surfaces of the

peripheral walls

30 a and 30 c of the box body 12 is shown in cross section. . Moreover, the outer peripheral side water stop wall 58 provided in the opening end surface 56 appears in the back, and the outer peripheral side water stop wall 58 is overlapped with the outer peripheral surface of the

peripheral walls

30a and 30c of the box main body 12. Can be confirmed.

Further, as shown in FIG. 7, the lower cover 16 has a wire lead-out hole 62 opened through the opening end face 56 at a central portion of the peripheral wall 50 b sandwiched between the elastic lock pieces 52. The electric wire 21 attached to can be pulled out from the electric wire outlet hole 62 to the outside. As a result, the wire lead-out hole 62 is formed in the formation region of the outer peripheral water stop wall 58 projecting from the opening end surface 56 across the peripheral walls 50a to 50c, and the outer peripheral water stop wall 58 is connected to the electric wire lead hole 62. Is divided in the circumferential direction. Further, as shown in FIG. 7, on the inner peripheral surface side of the peripheral wall 50 b, the opening end surface 56 of the lower cover 16 is obtuse with respect to the inner surface of the outer peripheral water stop wall 58 on both sides in the circumferential direction of the electric wire outlet hole 62. The inclined end face 64 is connected to each other. Thus, when the lower cover 16 is attached to the lower opening of the box body 12, the electric wire 21 led out from the wire lead-out hole 62 is sandwiched between the opening end surface 56 of the lower cover 16 and the end surface of the peripheral wall 30 b of the box body 12. Problems can be advantageously prevented. The obtuse angle: θ is more preferably set to an obtuse angle of 135 ° or more.

On the other hand, the bottom wall 66 of the lower cover 16 becomes the other lower end (left side in FIG. 4) in the longitudinal direction from the peripheral wall 50d side which is one upper end (right side in FIG. 4) in the longitudinal direction. It has the inclined surface 68 which inclines below toward the surrounding wall 50b side. Here, the downward inclination angle A (see FIGS. 4 and 8) of the inclined surface 68 can be arbitrarily set depending on the arrangement space of the electric junction box 10 or the like, but is set to 10 ° in the present embodiment. . Further,

drain holes

70a and 70b are respectively provided at both ends of the bottom wall 66 in the longitudinal direction which is the inclination direction. And the electric wire extraction hole 62 is provided in the surrounding wall 50b used as the other lower end part side located in the lowest end in the inclination direction of the bottom wall 66. FIG. As shown in FIG. 6, in this embodiment, the drain hole 70 a is provided immediately below the region G where the outer peripheral side water stop wall 58 and the inner peripheral side water stop wall 60 are divided in the circumferential direction. Even when the area G is submerged, quick drainage is secured from the drain hole 70a.

According to the electrical junction box 10 of the present embodiment having such a structure, the bottom wall 66 of the lower cover 16 is provided with the inclined surface 68 that is inclined downward from one upper end to the other lower end. It has been. In addition,

drain holes

70a and 70b are provided at both ends in the longitudinal direction of the electrical junction box 10 that is the direction of inclination of the inclined surface 68, respectively. Therefore, in the non-tilted state shown in FIG. 1 in which the motorcycle body is not tilted with respect to the ground plane, electrical connection is established from between the fitting surfaces of the box body 12, the upper cover 14, and the lower cover 16 in the electrical connection box 10. Water that has entered the inside of the box 10 and has reached the bottom wall 66 of the lower cover 16 is provided on the side of the peripheral wall 50b, which is the other lower end side located at the lowermost end, along the inclined surface 68 that is inclined downward. Water is collected toward the drainage hole 70a and drained quickly from the drainage hole 70a.

Next, the case where the motorcycle body is inclined with respect to the ground plane will be described with reference to FIGS. FIGS. 8A and 8B schematically show a case in which the vehicle body 72 of the motorcycle is inclined with respect to the ground plane 74. In FIGS. 8A and 8B, for easy understanding, the vehicle body 72 and the ground plane 74 are conceptually indicated by phantom lines, and the cross section of the electrical junction box 10 is enlarged. .

FIG. 8A shows a state in which the motorcycle is parked by the side stand 76 with the vehicle body 72 itself tilted to the left with respect to the ground plane 74. In this case,

drain holes

70a, 70b provided in the inclined surface 68 are spaced apart in the left-right direction of the motorcycle, and the lower end of the inclined surface 68 and the peripheral wall 50b are positioned on the left side that descends during parking. While the electrical junction box 10 is mounted on the vehicle body 72, a drain hole 70a is disposed on the peripheral wall 50b side which is the lowermost end of the inclined surface 68. Thereby, in the bottom wall 66 of the lower cover 16 at the time of parking, the inclination of the inclined surface 68 toward the drain hole 70a becomes steep by an inclination angle α from the non-inclined state (vertical direction) with respect to the ground surface 74 of the vehicle body 72. (A + α), the water collecting effect toward the drainage hole 70a and the drainage effect from the drainage hole 70a can be more advantageously exhibited.

FIG. 8B shows a state in which the vehicle body 72 itself is inclined to the right side with respect to the ground plane 74 by an inclination angle: β when the motorcycle curves to the right side during traveling or is accidentally inclined to the right side. Has been. In this case, when the electrical connection box 10 is inclined by an inclination angle: β with respect to the vertical direction, the end portion on the peripheral wall 50d side which is the uppermost end of the inclined surface 68 in the non-inclined state (right side in FIG. 8) It will be located at the lowest end in the vertical direction, and the inclined surface 68 will be inclined downward toward the end on the side of the peripheral wall 50d. Thus, water is collected at one upper end portion along the inclined surface 68, and can be quickly drained from the drain hole 70b provided at one upper end portion.

That is, in the conventional structure, it is assumed that the vehicle body 72 is in a non-inclined state with respect to the ground surface 74, and a drainage hole is provided only on the lower end side in the inclination direction of the inclined surface 68 in the non-inclined state. When the vehicle body 72 is inclined in a direction opposite to the inclined surface 68 inclined downward, there is a problem that water collected on the side where the drain hole is not provided on the inclined surface 68 is not drained. In the present embodiment, since the drain holes 70a and 70b are provided at both end portions of the inclined surface 68 in the inclination direction, the drain hole 70b is provided even when the vehicle body 72 is inclined in the opposite direction to the inclined surface 68 inclined downward. Can be quickly drained from Therefore, even when the electric junction box 10 according to the present embodiment is mounted on a motorcycle in which the vehicle body 72 is inclined with respect to the ground plane 74, an effective drainage effect suitable for the motorcycle can be exhibited.

As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited by the specific description. For example, the installation direction and position of the electrical junction box 10 to the vehicle can be arbitrarily set. Specifically, in another embodiment shown in FIG. 9, the upper end (the peripheral wall 50d side) of the inclined surface 68 is positioned on the left side that descends during parking, and the upper side of the inclined surface 68 when the vehicle body 72 is parked. The electric junction box 10 is mounted on the vehicle body 72 so that the end portion is located below the lower end portion (the peripheral wall 50b side) in the vertical direction (vertical direction in FIG. 9). Thus, even when the vehicle body 72 is inclined in the opposite direction to the inclined surface 68 inclined downward, the drain hole 70b is also provided in one upper end portion, so that quick drainage from the drain hole 70b can be realized. It is. In addition, it is possible to prevent a problem that the inclination angle of the inclined surface 68 at the time of parking becomes larger as it is closer to the vertical and the drainage is hindered.

In addition, an electric wire outlet hole 62 is formed in the peripheral wall 50b which is the side wall on the lower end side of the inclined surface 68 of the lower cover 16. In the present embodiment, when the vehicle body 72 is parked, the lower end (the peripheral wall 50b side) of the inclined surface 68 is positioned higher in the vertical direction than the upper end (the peripheral wall 50d side). Drainage from the electric wire outlet hole 62 formed in the peripheral wall 50b on the lower end side is advantageously prevented. As a result, it is possible to prevent the possibility that the waste water travels through the electric wire 21 and causes a failure in the electric system.

Moreover, in this embodiment, although the aspect which mounted the electrical-connection box 10 in the motorcycle was shown, it is not limited to this. For example, even when the electric junction box 10 is a four-wheeled vehicle as a vehicle in which the vehicle body is not inclined with respect to the ground surface, depending on the inclination state of the road surface, one upper end portion (the drain hole 70b side) of the inclined surface 68 is provided. The case where it is located vertically lower than the other lower end (drainage hole 70a side) is also assumed. Even in such a case, rapid drainage is promoted from the drainage hole 70b at one upper end, and an effective drainage effect is exhibited.

In addition, the inclination angle of the inclined surface 68 provided on the bottom wall 66 of the lower cover 16 and the number and positions of the drain holes can be appropriately changed in consideration of the installation space of the electrical connection box, the possibility of being wetted, and the like.
