Electric distribution box
View Patent ↗An electric distribution box includes a substrate, a first connector fitting part which includes first terminals, wherein one end portions of the first terminals are electrically connected to the substrate and the other end portions of the first terminals are disposed above the substrate so as to fit with the first connectors in a fitting direction parallel to the substrate, a second connector fitting part which includes a second terminal, wherein one end portion of the second terminal is electrically connected to the substrate and the other end portion of the second terminal is disposed above the substrate so as to fit with the second connector in a direction opposite to the fitting direction, electronic components on the substrate, a case body, and a cover which closes an opening part of the case body.
1. An electric distribution box comprising:
a substrate;
a first connector fitting part which includes a plurality of first terminals and a terminal holding part which holds the plurality of first terminals, wherein one end portions of the first terminals are electrically connected to the substrate and the other end portions of the first terminals are configured to be electrically connected to terminals of a plurality of first connectors respectively, and the other end portions of the plurality of first terminals are disposed above the substrate so as to fit with the plurality of first connectors in a fitting direction parallel to the substrate;
a second connector fitting part which includes a second terminal, wherein one end portion of the second terminal is electrically connected to the substrate and the other end portion of the second terminal is configured to be electrically connected to a terminal of a second connector, and the other end portion of the second terminal is disposed above the substrate so as to fit with the second connector in a direction opposite to the fitting direction of the first connectors;
a plurality of electronic components which is surface-mounted on the substrate;
a bottomed tubular case body which integrally forms a second connector accommodating part configured to accommodate the second connector on a bottom wall thereof, and accommodates the substrate inserted from a direction same as the fitting direction of the first connectors; and
a cover which integrally forms a first connector accommodating part configured to accommodate the plurality of first connectors, and closes an opening part of the case body.
2. The electric distribution box according to claim 1 , wherein the first connector fitting part and the second connector fitting part are arranged in a direction orthogonal to the fitting direction and in a direction parallel to the substrate; and
wherein at least one of the electronic components is disposed between the first connector accommodating part and the substrate, between the second connector accommodating part and the substrate, as well as between the second connector accommodating part and the cover.
3. The electric distribution box according to claim 1 , wherein the second connector is connected to a module cable of a control box connected to a trunk line extending in a front-rear direction of a vehicle;
wherein the plurality of first connectors are respectively connected to connection cables respectively connected to auxiliary devices of a vehicle module disposed in the vehicle; and
wherein power and a signal supplied from the second connector are distributed to the plurality of first connectors separately.
