Abstract

An electrical connection box includes a bracket insertion member having an insertion hole for receiving an insertion plate of a fixing bracket on an automobile. The insertion hole includes edge insertion holes into which edges of the insertion plate of the fixing bracket are inserted. Additionally, a guide surface is formed on an opening of each edge insertion hole such that the guide surface extends obliquely out from the opining in directions opposite to the direction of insertion of the insertion plate into the insertion hole. Each guide surface extends out in the direction along which the edge insertion holes oppose each other and in directions orthogonal to the direction along which the edge insertion holes oppose each other. The dimension W between the outer edge of each opening and the outer edge of the respective guide surface is no less than the thickness t of the insertion plate.

Claims

1. An electrical connection box comprising a bracket insertion member (18) having an insertion hole (16) into which an insertion plate (14) of a fixing bracket (12) provided on an automobile is inserted,

the insertion hole (16) including edge insertion holes (42) into which edge portions (34) of the insertion plate (14) of the fixing bracket (12) are inserted,

a guide surface (47) being formed on an opening of each edge insertion hole (42), the guide surface (47) extending obliquely out from the opening in directions opposite to the direction of insertion of the insertion plate (14) into the insertion hole (14),

each guide surface (47) extending out in a direction along which the edge insertion holes (42) oppose each other and in directions orthogonal to the direction along which the edge insertion holes (42) oppose each other, and

in a planar view of the bracket insertion member (18), a dimension between an outer edge of each opening and an outer edge of the associated guide surface is no less than a thickness of the insertion plate (14).

2. The electrical connection box of claim 1, wherein each guide surface (47) extends in a generally conical shape around the opening of the associated edge insertion hole (42).

3. The electrical connection box of claim 2, wherein a finger-engaging portion (56) is formed on a rear side of each guide surface (47) along outer peripheries of the bracket insertion member (18), the finger-engaging portion (56) widening towards the opening of the edge insertion hole (42) from an intermediate point along the depth of the edge insertion hole (42).

4. The electrical connection box of claim 2, wherein each guide surface is inclined with respect to a central axis of the edge insertion hole (42) at an angle of between 30 degrees and 60 degrees.
