Abstract
Abstract A plastic conduit affixed to and extending from the end of an electrical connector to transmit radial and axial forces, acting on the electrical wires leading to the connector, away from the connection of the connector contacts and electrical wires. The plastic cable support includes a plurality of axial slots that permit the cable support to be compressed into the wires passing through the conduit so that the wires may be retained in a fixed position. The plastic cable support transmits the redial and axial forces away from the connection of the wires to the contacts at least the distance of the cable support.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
268 words
In combination with an electrical connector of the type having several wires connected thereto, the improvement comprising: means for supporting said wires a predetermined distance from said connector, said supporting means including a conduit comprised of nonresilient material through which said wires pass, said conduit being a unitary integral structure comprising: a frusto-conical conduit portion a first cylindrical and rigid conduit portion extending from the larger end of said frusto-conical portion, said first cylindrical portion including a shoulder thereon facing said frusto-conical portion; a second cylindrical conduit portion extending from the smaller end of said frusto-conical portion and terminating in a free end, said second cylindrical portion including a shoulder at said free end that faces said frusto-conical portion; and at least one axial slot in said second cylindrical portion and said frusto-conical portion that extends the entire axial length of said second cylindrical portion and along at least a portion of said frusto-conical portion whereby said second cylindrical portion is compressible; means for engaging said shoulder on said first cylindrical portion of said conduit and demountably attaching said wire supporting means to said connector so that the rigid portion of said conduit is closer to said connector than said second cylindrical portion; and means for compressing and holding said second cylindrical portion of said conduit against said wires so that said electrical wires passing through said conduit are retained in fixed position, whereby when said conduit is attached to said connector and said compressible portion of said conduit is compressed said wires leaving said connector are supported by said conduit for a predetermined distance from said connector.
Claim 2
Dependent Claim
268 words
In combination with an electrical connector of the type having several wires connected thereto, the improvement comprising: means for supporting said wires a predetermined distance from said connector, said supporting means including a conduit comprised of nonresilient material through which said wires pass, said conduit being a unitary integral structure comprising: a frusto-conical conduit portion a first cylindrical and rigid conduit portion extending from the larger end of said frusto-conical portion, said first cylindrical portion including a shoulder thereon facing said frusto-conical portion; a second cylindrical conduit portion extending from the smaller end of said frusto-conical portion and terminating in a free end, said second cylindrical portion including a shoulder at said free end that faces said frusto-conical portion; and at least one axial slot in said second cylindrical portion and said frusto-conical portion that extends the entire axial length of said second cylindrical portion and along at least a portion of said frusto-conical portion whereby said second cylindrical portion is compressible; means for engaging said shoulder on said first cylindrical portion of said conduit and demountably attaching said wire supporting means to said connector so that the rigid portion of said conduit is closer to said connector than said second cylindrical portion; and means for compressing and holding said second cylindrical portion of said conduit against said wires so that said electrical wires passing through said conduit are retained in fixed position, whereby when said conduit is attached to said connector and said compressible portion of said conduit is compressed said wires leaving said connector are supported by said conduit for a predetermined distance from said connector.
Claim 3
Dependent Claim
268 words
In combination with an electrical connector of the type having several wires connected thereto, the improvement comprising: means for supporting said wires a predetermined distance from said connector, said supporting means including a conduit comprised of nonresilient material through which said wires pass, said conduit being a unitary integral structure comprising: a frusto-conical conduit portion a first cylindrical and rigid conduit portion extending from the larger end of said frusto-conical portion, said first cylindrical portion including a shoulder thereon facing said frusto-conical portion; a second cylindrical conduit portion extending from the smaller end of said frusto-conical portion and terminating in a free end, said second cylindrical portion including a shoulder at said free end that faces said frusto-conical portion; and at least one axial slot in said second cylindrical portion and said frusto-conical portion that extends the entire axial length of said second cylindrical portion and along at least a portion of said frusto-conical portion whereby said second cylindrical portion is compressible; means for engaging said shoulder on said first cylindrical portion of said conduit and demountably attaching said wire supporting means to said connector so that the rigid portion of said conduit is closer to said connector than said second cylindrical portion; and means for compressing and holding said second cylindrical portion of said conduit against said wires so that said electrical wires passing through said conduit are retained in fixed position, whereby when said conduit is attached to said connector and said compressible portion of said conduit is compressed said wires leaving said connector are supported by said conduit for a predetermined distance from said connector.
Claim 4
Dependent Claim
268 words
In combination with an electrical connector of the type having several wires connected thereto, the improvement comprising: means for supporting said wires a predetermined distance from said connector, said supporting means including a conduit comprised of nonresilient material through which said wires pass, said conduit being a unitary integral structure comprising: a frusto-conical conduit portion a first cylindrical and rigid conduit portion extending from the larger end of said frusto-conical portion, said first cylindrical portion including a shoulder thereon facing said frusto-conical portion; a second cylindrical conduit portion extending from the smaller end of said frusto-conical portion and terminating in a free end, said second cylindrical portion including a shoulder at said free end that faces said frusto-conical portion; and at least one axial slot in said second cylindrical portion and said frusto-conical portion that extends the entire axial length of said second cylindrical portion and along at least a portion of said frusto-conical portion whereby said second cylindrical portion is compressible; means for engaging said shoulder on said first cylindrical portion of said conduit and demountably attaching said wire supporting means to said connector so that the rigid portion of said conduit is closer to said connector than said second cylindrical portion; and means for compressing and holding said second cylindrical portion of said conduit against said wires so that said electrical wires passing through said conduit are retained in fixed position, whereby when said conduit is attached to said connector and said compressible portion of said conduit is compressed said wires leaving said connector are supported by said conduit for a predetermined distance from said connector.
