Appliance cord-connecting structure

Claim 2

In a portable appliance with an electric cord connected to terminals within the appliance by a portion of the cord having separated conductors to conduct power to the appliance, the improvement in the cord-appliance connection comprising; an elongated flexible sleeve bushing surrounding said cord and anchored to the appliance preventing sharp cord bends at the appliance, said cord extending into a selected length of the bushing and being turned to provide twisted conductors therein at least 90* lengthwise, strain relief means between the bushing anchor and terminals acting on the conductors, a cavity in said bushing over said selected length to accommodate the twisted conductors, and means rotationally restraining said conductors from untwisting, whereby minimal stress is imposed on said conductors at said terminals or at said bushing during flexing.

Claim 3

Apparatus as described in claim 1 wherein the rotationally restraining connecting means is disposed within said bushing.

Claim 4

Apparatus as described in claim 1 wherein said bushing has a length beyond said selected length with an opening therethrough conforming to the cross section of and rotationally restraining said cord.

Claim 5

Apparatus as described in claim 3 wherein said cord is a parallel non-round conductor cord with the cross section pressing on said parallel conductors and said separated conductor portion extends into said selected bushing length.

Claim 6

Apparatus as described in claim 1 wherein the cord covering over said conductors is a chlorosulphonated polyethylene that is molded over said conductors and is formed to rippably separate said conductors.

Claim 7

Apparatus as described in claim 4 wherein the cord is a flat wire cord flexible to bending across its narrow dimension and resistant across its wide dimension.

Claim 8

In a flatiron with an electric cord secured to terminals within the iron by a portion of the cord having separated conductors to conduct power to the iron, the improvement in the cord-iron connection comprising; an elongated flexible sleeve bushing surrounding said cord and anchored to the iron at one end thereof preventing sharp cord bends at the iron, said bushing having lengths of different internal cross sections about said cord, said separated conductor portion of said cord extending into a selected lengTh of said bushing having an internal cross section larger than said cord, each conductor being twisted lengthwise at least 90* lengthwise around the adjacent conductor, means between the twisted conductors and terminals to compress the separated conductors against the iron, the twisted conductors being disposed in said selected bushing length, the remainder of said bushing length having an internal cross section conforming to the cross section of and rotationally restraining said cord, whereby no stress is imposed on said conductors at said terminals or in said bushing during flexing.

Claim 9

In a flatiron with an electric cord secured to terminals within the iron by a portion of the cord having separated conductors to conduct power to the iron, the improvement in the cord-iron connection comprising; an elongated flexible sleeve bushing surrounding said cord and anchored to the iron at one end thereof preventing sharp cord bends at the iron, said bushing having lengths of different internal cross sections about said cord, said separated conductor portion of said cord extending into a selected lengTh of said bushing having an internal cross section larger than said cord, each conductor being twisted lengthwise at least 90* lengthwise around the adjacent conductor, means between the twisted conductors and terminals to compress the separated conductors against the iron, the twisted conductors being disposed in said selected bushing length, the remainder of said bushing length having an internal cross section conforming to the cross section of and rotationally restraining said cord, whereby no stress is imposed on said conductors at said terminals or in said bushing during flexing.

Claim 10

Apparatus as described in claim 7 wherein said cord is a parallel non-round conductor cord with the bushing cross section pressing on said parallel conductors.

Claim 11

Apparatus as described in claim 7 wherein the cord covering over said conductors is a chlorosulphonated polyethylene that is molded over said conductors and is formed to rippably separate said conductors.

Claim 12

Apparatus as described in claim 8 wherein the cord is a flat wire cord flexible to bending across its narrow dimension and resistant across its wide dimension.

Claim 13

Apparatus as described in claim 10 wherein said internal cross section adjacent said bushing anchor is substantially round and the remaining internal bushing cross section under said pressed cross section is substantially flat.
