Abstract
An electrical cord can include a cord segment with a receptacle. The receptacle can have a surface and apertures that accept a plug to form an electrical connection between the plug and wires of the electrical cord. A wear ring can be on the receptacle. The wear ring can be at least as large as the receptacle in a transverse cross-section. The wear ring can inhibit or prevent at least a portion of the surface from contacting a ground surface when the receptacle is on the ground surface or is dragged along the ground surface.
Claims24
An electrical cord assembly comprising:
- a cord segment having one or more wires;
- an electrical plug receptacle connected to an end of the cord segment, the receptacle including one or more apertures configured to receive an electrical plug to form an electrical connection between the plug and the one or more wires;
- and
- a wear ring configured to engage and surround at least a portion of the receptacle;
- wherein:
- the wear ring is sized and configured to inhibit at least a portion of a surface of the receptacle adjacent to the one or more apertures from contacting a ground surface when the end of the cord segment is on the ground surface;
- the wear ring comprises a plurality of wear ring portions configured to be assembled together to releasably engage and surround the portion of the receptacle;
- and
- the wear ring is removable from the electrical cord by disassembling the wear ring portions.
An electrical cord comprising:
- a cord segment comprising a wire;
- a receptacle on an end of the cord segment, the receptacle comprising a connection surface including an aperture, the connection surface configured to receive an adapter to form an electrical connection between the adapter and the wire via the aperture;
- and
- a wear member on the receptacle, the wear member configured to inhibit at least a portion of the connection surface from contacting a ground surface when the receptacle is on the ground surface.
An electrical cord reel comprising:
- a spool member rotatable about a winding axis;
- and
- an electrical cord comprising:
- a cord segment having a plurality of wires;
- a connector at a first end of the cord segment;
- an electrical plug receptacle connected to a second end of the cord segment, the receptacle including one or more apertures configured to receive at least one electrical plug to form an electrical connection between the plug and one or more of the wires;
- and
- a wear ring engaged with and surrounding the receptacle;
- wherein:
- the wear ring is sized and configured to substantially prevent surfaces of the receptacle adjacent to the one or more apertures from contacting a ground surface when the end of the cord segment is dragged along the ground surface;
- the wear ring comprises a plurality of wear ring portions configured to be assembled together to engage and surround the receptacle;
- the wear ring is removable from the electrical cord by disassembling the wear ring portions;
- the connector is connected to the spool member;
- the reel is configured to convey electrical power to the connector;
- the electrical cord is configured to become spooled onto the spool member when the spool member rotates in a first direction about the winding axis;
- and
- the electrical cord is configured to become unspooled from the spool member when the spool member rotates in a second direction about the winding axis, the second direction being opposite the first direction.
