First Claim
Patent Images
1. An electric connection box comprising:
- a circuit substrate including a wiring and a via hole connected to the wiring;
a resin plate including a connector terminal soldered to the via hole, the resin plate being integrated with the circuit substrate;
a casing including an opening part having an opening side through which the circuit substrate and the resin plate are inserted to be housed in the opening part; and
a housing positioned in the opening part and functioning as a cover closing the opening side of the casing, the resin plate being interposed between and held by the housing and the casing, whereinthe circuit substrate is supported by the housing and the casing through the resin plate held between the housing and the casing while the circuit substrate is spaced from the housing and the casing;
the casing includes a bottom side wall opposite from the opening side,the circuit substrate includes an edge surface that faces to the bottom side wall of the casing without contacting the bottom side wall, and a pair of opposed surfaces spreading approximately perpendicular to the resin plate without contacting the casing or the housing.

Abstract
An electric connection box includes a resin plate having a connector terminal soldered to a via hole of a circuit substrate. The circuit substrate and the resin plate are inserted to be housed in an opening part of a casing of the electric connection box. A housing is positioned in the opening part and functioning as a cover closing an opening side of the casing. The circuit substrate is supported by the housing and the casing through the resin plate that is held between the housing and the casing while the circuit substrate is spaced from the housing and the casing.
