Abstract
Abstract An electrical junction box having a plurality of holes into which are inserted hole cushions which are fitted to the periphery of the holes to protect electrical wires entering the junction box from the bare edges which form the holes. Top and bottom insulated cushions further protect the electrical wires from contacting interior sides of the top and floor of the junction box. Wire guards are provided which surround the insulated electrical wires to allow the insulated wires to be secured by clamping means to the electrical junction box without the electrical wires actually coming into direct contact with the clamping means.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
258 words
An electrical junction box, for reducing the risk of fire, having a floor integrally connected to a plurality of sidewalls, at least one sidewall of the plurality of sidewalls having a hole extending from an interior side of the at least one sidewall to an exterior side of the at least one sidewall, and a top connected to the plurality of sidewalls which is detachable therefrom, said electrical junction box further comprising: a connector clamp having an annular face connected to the at least one sidewall at the periphery of the hole of the at least one sidewall, an exterior side of the annular face connected to a screw-nut clamp having upper and lower clamping elements, an interior side of the annular face connected to a tubular threaded portion of said connector clamp, a wingnut screwed into the tubular threaded portion securing said connector clamp to the at least one sidewall; an insulated wire; a wire guard connected to and surrounding said insulated wire, said wire guard connected to and positioned between the upper and lower clamping elements and extending through the hole of the at least one sidewall and through the interior of the threaded portion of said connector clamp; a top insulation pad connected to the top of said junction box; a bottom insulation pad connected to the floor of said junction box; a second sidewall of said plurality of sidewalls having a hole extending therethrough; and a hole cushion connected to said second sidewall at the peripheral edge of the hole of said second sidewall.
Claim 2
Dependent Claim
258 words
An electrical junction box, for reducing the risk of fire, having a floor integrally connected to a plurality of sidewalls, at least one sidewall of the plurality of sidewalls having a hole extending from an interior side of the at least one sidewall to an exterior side of the at least one sidewall, and a top connected to the plurality of sidewalls which is detachable therefrom, said electrical junction box further comprising: a connector clamp having an annular face connected to the at least one sidewall at the periphery of the hole of the at least one sidewall, an exterior side of the annular face connected to a screw-nut clamp having upper and lower clamping elements, an interior side of the annular face connected to a tubular threaded portion of said connector clamp, a wingnut screwed into the tubular threaded portion securing said connector clamp to the at least one sidewall; an insulated wire; a wire guard connected to and surrounding said insulated wire, said wire guard connected to and positioned between the upper and lower clamping elements and extending through the hole of the at least one sidewall and through the interior of the threaded portion of said connector clamp; a top insulation pad connected to the top of said junction box; a bottom insulation pad connected to the floor of said junction box; a second sidewall of said plurality of sidewalls having a hole extending therethrough; and a hole cushion connected to said second sidewall at the peripheral edge of the hole of said second sidewall.
Claim 3
Dependent Claim
109 words
An electrical junction box according to claim 1, further comprising: a third sidewall of said plurality of sidewalls having a hole extending therethrough; a push-through rubber nipple connected to the peripheral edge of the hole of said third sidewall and having an annular clamping region directed to the exterior of said junction box, said push-through nipple forming an entry path into said junction box; a thinly insulated wire extending into said electrical junction box through the entry path formed by said push-through rubber nipple; a clamp fastened to the clamping region of said push-through rubber nipple so as to secure said thinly insulated wire to said push-through rubber nipple.
Claim 4
Dependent Claim
89 words
An electrical junction box according to claim 2, further comprising: a fourth sidewall of said plurality of sidewalls having a hole extending therethrough; a second hole cushion connected to the fourth sidewall at the peripheral edge of the hole of said fourth sidewall; a second insulated wire extending into said electrical junction box through said second hole cushion; an interior clamp secured to the interior of the fourth sidewall; a second wire guard connected to and surrounding said second insulated wire, said second wire guard contacting said interior clamp.
Claim 5
Dependent Claim
19 words
A junction box according to claim 3, wherein said hole cushion and said second hole cushion are rubber grommets.
Claim 6
Dependent Claim
23 words
A junction box according to claim 4 wherein said wire guard and said second wire guard are made of a vinyl plastic material.
