An electric wire is inserted through a through hole formed with a housing body. A first terminal fitting is provided with a first clamper which clamps a portion of the electric wire situated inside of the housing body to electrically connect therewith. A second terminal fitting is provided with a second clamper which clamps a portion of the electric wire situated outside of the housing body. A grommet made of an elastic material has a cylindrical shape such that the electric wire is passed through an inner periphery thereof and an outer periphery thereof is fitted into the through hole of the housing body. A reinforcing spacer is provided on a part of the outer periphery of the grommet so as to abut against at least one of a first edge of the through hole at an outer face of the housing body and a second edge of the through hole at an inner face of the housing body. The reinforcing spacer is made of a material having greater hardness than the elastic material forming the grommet.

Waterproof structure for terminal portion of electric wire provided on housing body for electric components

Electric contact portions that contact terminals are formed for a first holder, and pressing portions are formed for a second holder to press terminals against the electric contact portions. In addition, provided for the pressing portions are a pair of first position regulators, which contact, at two places in the widthwise direction of the terminals, the outer walls of the terminals, and a pair of second position regulators, which, in the longitudinal direction of the terminals, contact the ends of the terminals.

Electromagnetic wave shielding structure

In a drain structure for an electric connection box, a drain hole (5) for discharging water permeating within a case (4) is provided in a bottom wall (4a) of the case (4) of an electric connection box (1) having a terminal insertion port (3b) of a terminal receiving portion (3); and a permeation prevention wall (6) for preventing the water discharged from the drain hole (5) from permeating within the terminal receiving portion (3) is provided at least in a portion between a discharge port (5a) of the dram hole (5) and the terminal insertion port (3b) of bottom wall surface (4b) close to the discharge port (5a) of the drain hole (5) in a projecting manner.
