Abstract
Abstract The invention is directed to a combined guide and barrier for the edge mounting of ciruit boards within a housing. The barrier guides are designed to be used in multiples in high density packing applications. The barrier guide includes a top, a bottom and a barrier extending between the top and bottom. The top and bottom have opposed grooves facing one another. The grooves guide and position the printed circuit within the housing. The barrier, positioned near and parallel to the grooves and extending along the length of the top and bottom, helps prevent the user from inadvertently coming into contact with exposed edge connectors or adjacent circuit boards after a circuit board is removed from the housing. The barrier also guides cooling air through the housing.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
127 words
A circuit board barrier guide for mounting a circuit board, having first and second edges, in a housing comprising: an elongate base including a first support groove for receipt of the first edge therein; an elongate top having a second support groove facing a first support groove for receipt of the second edge therein; and an elongate, planar barrier including first and second barrier portions, the base and the first barrier portion being a unitary extruded piece, the first and second barrier portions including respective first and second outer edges positioned adjacent one another and configured for complementary mating engagement with portions overlapping, the barrier spaced apart from the first and second grooves a chosen distance to form a channel between the barrier and a circuit board.
Claim 2
Dependent Claim
127 words
A circuit board barrier guide for mounting a circuit board, having first and second edges, in a housing comprising: an elongate base including a first support groove for receipt of the first edge therein; an elongate top having a second support groove facing a first support groove for receipt of the second edge therein; and an elongate, planar barrier including first and second barrier portions, the base and the first barrier portion being a unitary extruded piece, the first and second barrier portions including respective first and second outer edges positioned adjacent one another and configured for complementary mating engagement with portions overlapping, the barrier spaced apart from the first and second grooves a chosen distance to form a channel between the barrier and a circuit board.
Claim 3
Dependent Claim
35 words
The barrier guide of claim 1 wherein the top and second barrier portion is a unitary extruded piece and wherein the base and first barrier portion is identical to the top and second barrier portion.
Claim 4
Dependent Claim
26 words
The barrier guide of claim 2 wherein the top and second barrier portion are positioned upside down with respect to the base and first barrier portion.
Claim 5
Dependent Claim
24 words
The barrier guide of claim 1 wherein the base includes a third groove positioned on a side of the barrier opposite the first groove.
Claim 6
Dependent Claim
18 words
The barrier guide of claim 1 wherein the barrier is constructed to act as an electromagnetic radiation shield.
Claim 7
Dependent Claim
24 words
The barrier guide of claim 5 wherein the barrier is made of plastic with a lower of metal to create the electromagnetic radiation shield.
