Abstract:
1. A junction box assembly, comprising: a first structure with a first sidewall, the first structure having a receiving member; and a second structure with a second sidewall, the second structure having a T-shaped aligning protrusion extending beyond an edge of the second sidewall in an engagement direction, wherein the receiving member begins to mate with the T-shaped aligning protrusion before the first sidewall and the second sidewall come into contact as the first and second structures are engaged in the engagement direction, and the T-shaped aligning protrusion includes a small-width portion and a large-width portion which is attached to the small-width portion, the large-width and small-width portions extending along the second sidewall and beyond the edge of the second sidewall in the engagement direction, the large-width portion being received in the receiving member so that the large-width portion restricts the second sidewall from separating from the receiving member in a direction perpendicular to the engagement direction when the first and second structures are engaged.
