ABSTRACT:
When a car suffers a collision, a shock is applied to the body of an electrical connection box in the car. Due to the shock, an external force is applied horizontally to the peripheral wall of the body and the cover, thus crushing inverted V-shaped grooves formed on the bottom surface of the body and reducing the complementary angle .theta. between the two inclined surfaces of each inverted V-shaped groove. The external force applied horizontally to the peripheral wall of the body and the cover is also absorbed by the release of the cover from the body. The release of the cover from the body is accelerated by a force not absorbed by the deformation of the inverted V-shaped grooves but applied to the body vertically upwardly. Consequently, the effect of the external force applied to the electrical connection box is reduced. As a result of the absorption of the shock, a small degree of force is applied to a junction box or component in the box. Risk of damage to the junction box is reduced and disconnection of wiring from the junction box is unlikely.
