Abstract
Abstract The embodiment of the disclosure disclosed herein is directed to a wire bundle centering grommet and strain relief for use in supporting a plurality of wires or a multi-conductor cable at a spaced location from the periphery of an aperture passing through a wall panel. The centering grommet and strain relief is formed of first and second semi-circular members hinged together at mating edges to form a cylindrical body which is inserted into an aperture in a wall panel. A flange is formed at one edge of the cylindrical body to form a stop-surface. Tabs are formed along the cylindrical body and have a sloping wall facing the flange to accept wall panels of various thicknesses. The tabs are urged inwardly as a result of the inherent resiliency of the cylindrical body when inserting the centering grommet and strain relief into the aperture of the wall panel. Arms extend substantially inwardly and axially of the cylindrical body and are provided with the strap and retainer means to wrap around the wire bundle firmly to hold it in place at a spaced position relative to the periphery of the aperture passing through the wall panel.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
165 words
A wire bundle centering grommet and strain relief, comprising in combination; first and second semicircular members hinged together at mating edges to form a cylindrical body adapted to be inserted into an aperture formed in a wall panel, a flange formed at one edge of said cylindrical body to abut the peripheral margin about said aperture, tab means extending outwardly of said cylindrical body and displaced from said flange to receive the wall panel therebetween firmly to hold the cylindrical body in place, first and second arm means extending axially from said first and second semi-circular members respectively, strap means secured to said first arm means and extending transversely thereof, and fastening means formed on at least one of the said first and second arm means to receive said strap means, whereby said strap means will wrap around and be secured to a bundle of wires passing through said cylindrical body to maintain the bundle of wires centrally of said aperture in said wall panel.
Claim 2
Dependent Claim
165 words
A wire bundle centering grommet and strain relief, comprising in combination; first and second semicircular members hinged together at mating edges to form a cylindrical body adapted to be inserted into an aperture formed in a wall panel, a flange formed at one edge of said cylindrical body to abut the peripheral margin about said aperture, tab means extending outwardly of said cylindrical body and displaced from said flange to receive the wall panel therebetween firmly to hold the cylindrical body in place, first and second arm means extending axially from said first and second semi-circular members respectively, strap means secured to said first arm means and extending transversely thereof, and fastening means formed on at least one of the said first and second arm means to receive said strap means, whereby said strap means will wrap around and be secured to a bundle of wires passing through said cylindrical body to maintain the bundle of wires centrally of said aperture in said wall panel.
Claim 3
Dependent Claim
62 words
The wire bundle centering grommet and strain relief according to claim 1 wherein said first and second arm means have a first portion, diverge inwardly toward the axis passing through said cylindrical body and have a second portion extending substantially parallel to the axis of said cylindrical body, said strap means and said fastening means being formed at said parallel portion thereof.
Claim 4
Dependent Claim
53 words
The wire bundle centering grommet and strain relief according to claim 2 wherein said strap means includes a plurality of spaced-apart notches and said fastening means includes aligned aperatures formed in said first and second arm means to receive the said strap and hold it in place by firm engagement with said notches.
Claim 5
Dependent Claim
50 words
The wire bundle centering grommet and strain relief according to claim 1 wherein said lock means is formed on said first and second arm means in substantial alignment with one another to Receive said strap means for locking said arm means to the periphery of a wire bundle passing therethrough.
Claim 6
Dependent Claim
49 words
The wire bundle centering grommet and strain relief as set forth in claim 1 wherein said flange formed on one edge of said body has a cut-off portion on each of said first and second semi-circular members to enable opening of said semi-circular members at said hinged-together mating edge.
Claim 7
Dependent Claim
59 words
The wire bundle centering grommet and strain relief as set forth in claim 1 wherein said first and second semi-circular members are hinged together by a tab formed on one of said first and second semi-circular members and a hole formed in the other of said first and second semicircular members for receiving said tab during a hinging motion.
Claim 8
Dependent Claim
54 words
The wire bundle centering grommet and strain relief as set forth in claim 1 wherein said strap means have a plurality of spaced-apart notches formed therealong, and said fastening means is formed by the pair of spacedapart apertures to receive said strap means and hold it in place by frictional engagement with said notches.
