Abstract

Abstract A reinforced junction box assembly includes: a polygonal open housing body with a top surface on one side and a plurality of side walls vertically formed along the periphery of the top surface; at least one pair of holding flanges each with a guide opening in the middle separately provided along an edge of two opposing sides of the open housing body structure; and at least one pair of mounting members each with a reinforced ridge and two mounting sides respectively fixed on an interior surface of the two opposing side walls against the holding flange. In addition, each of the mounting members includes a threaded bore in the reinforced ridge, which is aligned with the guide opening of the respective holding flange, and a plurality of screw holes in the mounting sides, which are used to fix the mounting members on the opposing side walls. Thereby, safe connections can be ensured all the time between the mounting members and a suspension load through the guide openings and the threaded bores.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 211 words
A reinforced junction box assembly having a polygonal open housing body formed with a top surface on one side thereof, a plurality of side walls vertically located along a periphery of the top surface, and at least one pair of holding flanges, each one of which has a guide opening in a middle portion thereof, integrally formed along each outer edge of two opposing side walls of the open housing body for providing an anchor position thereat; the improvement comprising: at least one pair of mounting means, each having a reinforced ridge formed between two mounting sides thereof with a threaded bore extending through said reinforced ridge, and a plurality of screw holes formed in said mounting sides for fixing the mounting means on an interior surface of the two opposing side walls of the housing body against the holding flanges thereof, with the threaded bores of said mounting means aligned with the guide openings of the holding flanges; both of said mounting means being fixed to an interior surface of the two opposing side walls against the holding flanges, whereby safe connections between said mounting means and a suspension load can be effectively made through the guide openings of the holding flanges and the threaded bores of said mounting means.
Claim 2
Dependent Claim 211 words
A reinforced junction box assembly having a polygonal open housing body formed with a top surface on one side thereof, a plurality of side walls vertically located along a periphery of the top surface, and at least one pair of holding flanges, each one of which has a guide opening in a middle portion thereof, integrally formed along each outer edge of two opposing side walls of the open housing body for providing an anchor position thereat; the improvement comprising: at least one pair of mounting means, each having a reinforced ridge formed between two mounting sides thereof with a threaded bore extending through said reinforced ridge, and a plurality of screw holes formed in said mounting sides for fixing the mounting means on an interior surface of the two opposing side walls of the housing body against the holding flanges thereof, with the threaded bores of said mounting means aligned with the guide openings of the holding flanges; both of said mounting means being fixed to an interior surface of the two opposing side walls against the holding flanges, whereby safe connections between said mounting means and a suspension load can be effectively made through the guide openings of the holding flanges and the threaded bores of said mounting means.
Claim 3
Dependent Claim 51 words
A reinforced junction box assembly according to claim 1 wherein each mounting means is a die-cast, solid metallic block and the threaded bore thereof is located so as to axially intersect the plane formed by the axes of said screw holes thereof so that reliable supporting capability can be achieved therewith.
