Electric junction box including electric unit in plural shield case members
View Patent ↗Providing an electric junction box, which can reduce a cost and the weight with maintaining shield effect, in the electric junction box including an electric unit and a shield case, a panel joint at a panel joining area of a conductive panel is formed with synthetic resin. The shield case can be formed with a thin sheet metal by press forming. The electric unit is received in the shield case, so that the electric junction box can maintain shield effect.
1. An electric junction box comprising:
an electric unit; and
a shield case receiving the electric unit,
wherein the shield case comprises a plurality of case members to be separated,
the case member comprising an electric conductive panel and a panel joint made of synthetic resin at a panel joining area of the electric conductive panel,
the electric conductive panel being formed out of sheet metal into a hollow rectangular solid shape with an opening at one surface of the electric conductive panel, and
wherein the plurality of case members are combined to each other so as to form a receiving space for receiving the electric unit in the shield case.
2. The electric junction box according to claim 1 , wherein the case members comprise respectively a combining piece made of synthetic resin to combine the mating case member, said combining piece projecting from the opening.
3. The electric junction box according to claim 1 , wherein the opening is formed in parallel to a plane, which is the smallest projected area of the shield case.
4. The electric junction box according to claim 1 , wherein the shield case comprises a mount portion for mounting the shield case on a mating object, said mount portion being formed integrally with the panel joint.
5. The electric junction box according to claim 1 , wherein a thickness of the panel is not smaller than at least minimum thickness to meet required shield effect.
6. The electric junction box according to claim 1 , wherein the panel is structured by combining plate panels.
7. The electric junction box according to claim 1 , wherein the panel is structured by combining panel members formed by bending a plate panel.
