Claim:
1. A connection assembly for rotateably coupling an electrical accessory component to a main device and providing electrical power from the main device to the accessory component, comprising: a housing portion; a port assembly rotateably coupled to the housing portion, the port assembly having a first end and a second end configured to pass a gas therethrough, the second end of the port assembly being coupled to the accessory component, the port assembly including an electrical connector member having a first connector end electrically coupled to the accessory component and a second connector end; and a wire assembly having an electrical wire member having a first end electrically coupled to the second connector end and a second end electrically coupled to a power supply of the main device, wherein a portion of the electrical wire member is spooled around the first end of the port assembly and encased in a chamber defined between the housing portion and the port assembly, wherein the housing portion includes a recess having a bottom surface, wherein the port assembly is rotateably received within the recess, wherein the chamber extends from a bottom surface of a base portion of the port assembly to the bottom surface of the recess in a direction perpendicular to the bottom surface of the recess, wherein the chamber is sized to prevent the portion of the electrical wire member from pinching or tangling during rotation of the port assembly, wherein the electrical wire member includes at least one wire having a wire diameter, and wherein a height of the chamber measured in the direction is between one and two times the wire diameter, and wherein rotation of the port assembly in a first direction causes the portion of the electrical wire member to spool more tightly around the first end of the port assembly and rotation of the port assembly in a second direction causes the portion of the electrical wire member to spool less tightly around the first end of the port assembly.
