Electric junction box

Abstract

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.

Claims

1. An electric junction box comprising: an electric unit; anda shield case receiving the electric unit, said shield case comprising electric conductive panels and a panel joint made of synthetic resin to be provided at a panel joining area.

2. The electric junction box according to claim 1, wherein the shield case comprises a plurality of case members to be separated, which are combined to each other so as to form a receiving space for receiving the electric unit in the shield case.

3. The electric junction box according to claim 2, wherein the case members comprise respectively a receiving section, which forms the receiving space for receiving the electric unit, and an opening formed at one end of the receiving section, said openings of the plurality of case members being combined to each other so as to form the shield case.

4. The electric junction box according to claim 3, 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.

5. The electric junction box according to claim 4, wherein the opening is formed in parallel to a plane, which is the smallest projected area of the shield case.

6. 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.

7. 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.
