Electronic component unit
View Patent ↗An electronic component unit includes a housing that accommodates electronic components therein and that is provided with connecting units connected to electric wires on a vertical-direction lower surface. The housing has protruding ribs protruding downward in a vertical direction from the vertical-direction lower surface, positioned between the connecting units and respective side wall surfaces of the housing provided to sides of the vertical-direction lower surface, and extending from one end to the other end of the vertical-direction lower surface along the side wall surfaces. The electronic component unit having this configuration can prevent adhesion of water to the connecting units.
1. An electronic component unit comprising:
a housing configured to accommodate an electronic component therein and provided with a connecting unit disposed on a vertical-direction lowermost surface of the housing for connecting to an electric wire in a vertical connection direction, wherein
the housing has a protruding rib protruding downward in a vertical direction from the vertical-direction lowermost surface, positioned between the connecting unit and a side wall surface of the housing provided to a side of the vertical-direction lowermost surface, and extending from a first end to a second end of the vertical-direction lowermost surface along the side wall surface, wherein
the vertical-direction lowermost surface of the housing has a substantially rectangular shape with two substantially parallel short sides and two substantially parallel long sides, and wherein
the protruding rib extends along a direction parallel to the long sides of the vertical direction lowermost surface of the housing.
2. The electronic component unit according to claim 1 , wherein
the housing has an inclined surface on the vertical-direction lowermost surface, the inclined surface inclining such that an end on a side wall surface side is positioned lower in the vertical direction than an end on a connecting unit side in a state where the housing is placed at an installation position, and
the protruding rib is provided in the inclined surface and extends in a direction intersecting with an inclination direction of the inclined surface.
3. The electronic component unit according to claim 2 , wherein
the housing has a draining step portion positioned adjacent to the connecting unit side at both ends of the protruding rib on the vertical-direction lowermost surface and recessed upward in the vertical direction with respect to a vertical-direction lower end of the protruding rib.
4. The electronic component unit according to claim 1 , wherein
the housing has a draining step portion positioned adjacent to a connecting unit side at both ends of the protruding rib on the vertical-direction lowermost surface and recessed upward in the vertical direction with respect to a vertical-direction lower end of the protruding rib.
5. An electronic component unit comprising:
a housing configured to accommodate an electronic component therein and provided with a connecting unit disposed on a vertical-direction lowermost surface of the housing for connecting to an electric wire in a vertical connection direction, wherein the housing has a protruding rib protruding downward in a vertical direction from the vertical-direction lowermost surface, positioned between the connecting unit and a side wall surface of the housing provided to a side of the vertical-direction lowermost surface, and extending from a first terminal end to a second terminal end of the vertical-direction lowermost surface along the side wall surface, wherein
the vertical-direction lowermost surface of the housing has a substantially rectangular shape with two substantially parallel short sides and two substantially parallel long sides, and wherein
the protruding rib extends along a direction parallel to the long sides of the vertical direction lowermost surface of the housing.
