The electrical junction box according to the embodiment will be described in detail below with reference to the drawings.
As shown in fig. 1, 8, and 9, the power supply box 10 as an electrical junction box includes: a center connector 20 located at the center of the power box 10 in the longitudinal direction, which will be described later; side connectors 30 located on both sides of the power box 10 in the longitudinal direction; a wire harness 40 that connects the center connector 20 and the side connector 30; and a case main body 11 made of synthetic resin for mounting the center connector 20 and the side connector 30. The power supply box 10 is disposed between a plurality of electric components of a vehicle such as an automobile and the output of a battery. For convenience of explanation, in fig. 1, a predetermined one direction parallel to a direction in which the side connectors 30 on both sides of the power supply box 10 are connected to each other is referred to as a longitudinal direction, a predetermined one direction perpendicular to the longitudinal direction and a direction in which the center connector 20 and the side connectors 30 are attached to the box body 11 is referred to as a height direction, and a direction perpendicular to the longitudinal direction and the height direction is referred to as a width direction. The directions "front and rear", "up and down", and the like are determined for convenience of description, and are not limited to the actual mounting posture of each element or the like.
As shown in fig. 3, the box main body 11 includes: a center connector accommodation recess 12 to which a center connector 20 is attached at the center of the box main body 11 in the longitudinal direction; bolt insertion holes 13 located on both sides in the longitudinal direction of the box main body 11; the side connector accommodation recess 14 having the slit 15 is attached with the lower portion 34 of the side connector 30 on the widthwise front side of the box main body 11 on both sides. The tank body 11 further includes: a side locked portion 16 for locking a side locking portion 33 of the side connector 30 at a position facing the slit 15; and a plurality of L-shaped wire holding portions 17a, 17b that hold the wire harness 40 routed below the slit 15. The wire holding portions 17a, 17b are formed to protrude from the side surface of the box body 11 in the width direction and the height direction of the box body 11. The box body 11 is fastened and fixed to a vehicle of an automobile via a bolt, not shown, or the like, inserted through the bolt insertion hole 13.
As shown in fig. 3 to 5 and 7, the center connector housing recess 12 is a through hole in which the center rectangular parallelepiped center connector 20 is mounted, and center locking projections 12a and 12a are integrally formed on opposite inner surfaces of the center connector housing recess 12, and the center locking projections 12a and 12a are locked with center locking portions 21 and 21 on both sides of the center connector 20.
As shown in fig. 3 to 5 and 7, the side connector accommodation recess 14 having the slit 15 is formed in a U-shape in cross section (the curved portion of the U is formed of right angles and straight lines at 2 points), and bottom wall portions 14a, 14a for placing the lower portion 34 of the side connector 30 are provided on the lower sides in the height direction of the opposite side surfaces in the width direction. As shown in fig. 3, 4, 6, and 7, the bottom surface 18 of the case main body 11 is divided into two parts, namely, one bottom surface and the other bottom surface, by the slit 15, and the one bottom surface and the other bottom surface are opposed to each other in the width direction. A reinforcing inclined rib 19 is integrally formed on a bottom surface (bottom surface on one side, widthwise front side of the box main body 11, upper side in fig. 7) 18b on the outer side of the side connector accommodating recess 14. As shown in fig. 4 and 7, the reinforcing inclined rib 19 is formed so as to incline with respect to the inner bottom surface (the other bottom surface, the rear side of the outer bottom surface 18b in the width direction of the box main body 11, and the lower side of the outer bottom surface 18b in fig. 7) 18a so as to narrow in width as it moves toward the slit 15. That is, the gap between the opposing outer bottom surface 18b and the inner bottom surface 18a is inclined with respect to the width direction and the longitudinal direction of the box body 11, and the gap becomes narrower as it moves to the outer side in the longitudinal direction where the slit 15 opens.
As shown in fig. 3 and 4, the side locked portion 16 is formed in a rectangular plate shape, and has an introduction groove portion 16a on the upper side of the center thereof for guiding the side locking portion 33 of the side connector 30. A rectangular side locking hole 16b is provided in the center of the side locked portion 16, and the side locking hole 16b is locked by a side locking protrusion, not shown, of the locking claw 33a of the side locking portion 33 of the side connector 30.
As shown in fig. 1 and 2, the center connector 20 is formed in a rectangular parallelepiped shape from synthetic resin, and center locking portions 21 that are engaged with the center engaging projections 12a of the center connector accommodating recess 12 are integrally formed on both side surfaces thereof. As shown in fig. 1, 2, and 9, a pair of center terminal accommodating chambers 22 and 22 are formed, and the pair of center terminal accommodating chambers 22 and 22 accommodate a male terminal, not shown, from the upper surface to the bottom surface of the center connector 20. As shown in fig. 8 and 9, a pair of wire harnesses 40, 40 connected to the respective male terminals accommodated in the pair of central terminal accommodation chambers 22, 22 are led out downward from the lower portion 23 of the central connector 20, and extend toward the lower portions 34 of the pair of side connectors 30, 30 on both sides.
As shown in fig. 1, 2, 8, and 9, the pair of side connectors 30 and 30 on both sides are made of synthetic resin, and have a cover portion 32 fitted with a connector on the mating side, not shown, at an upper portion 31 thereof. A side locking portion 33 that engages with and disengages from the side locked portion 16 of the box main body 11 is integrally formed on one side surface of the upper portion 31 of the side connector 30. The lower portion 34 of the side connector 30 is formed in a rectangular parallelepiped shape smaller than the upper portion 31, and is attached to the side connector accommodating recess 14 of the box main body 11 having the slit 15.
As shown in fig. 1 and 2, the side locking portion 33 is formed in a rectangular tube shape that accommodates the side locked portion 16 of the box main body 11. Further, an elastic sheet-like locking claw portion 33a is formed in the center of the side locking portion 33 via side locking slits 33b, 33b on both sides, and the locking claw portion 33a has a side locking protrusion, not shown, on the lower inner surface that is locked with the side locking hole portion 16b of the side locked portion 16.
As shown in fig. 9, a pair of side terminal accommodation chambers 35, 35 communicating with the hood 32 are formed in the lower portion 34 of the side connector 30. A female terminal 36 is accommodated in the side terminal accommodation chamber 35. The wire harness 40, one end portion 40a of which has been connected to the female terminal 36, is led out downward from the lower portion 34 of the side connector 30, and is routed below the slit 15 of the side connector accommodation recess 14, and the other end portion 40b thereof extends to the lower portion 23 of the center connector 20.
According to the power supply box 10 of the above embodiment, the inclined rib 19 formed on the bottom surface 18b on the outside of the box body 11 functions as a beam against the inward inclination force of the side connector accommodating recess 14 at both side wall portions sandwiching the slit 15 caused by the shrinkage of the resin occurring immediately after the resin molding of the box body 11. Since the inward tilting force of the side wall portions of the side connector accommodation recess 14 sandwiching the slit 15 is offset by the tilting rib 19, the side connector accommodation recess 14 having the slit 15 can be prevented from being tilted inward at the time of resin molding of the box main body 11. Accordingly, the side connector 30 can be simply and accurately attached to the side connector accommodating recess 14 of the box main body 11, and the wire harness 40 led out from the lower portion 34 of the side connector 30 can be routed below the slit 15 and held by the L-shaped wire holding portion 17 a. That is, the wiring operability of the wire harness 40 can be improved.
The present embodiment has been described above, but the present embodiment is not limited to this, and various modifications can be made within the scope of the present embodiment.
That is, according to the embodiment, the power supply box as the electric junction box is described, but it is also applicable to an electric junction box such as a relay box.
In addition, according to the above embodiment, the inclined rib for reinforcement is integrally formed on the outer bottom surface of the tank main body divided into two by the slit, but the inclined rib for reinforcement may be integrally formed on the inner bottom surface of the tank main body divided into two by the slit.
