Claim 12:
13. An artificial tree, comprising:
a first tree portion, including:
a first trunk segment;
a first plurality of wires;
a sleeve attached around an outer surface of a portion of the first trunk segment;
a first electrical connector, including:
a first connector body, including a first cylindrical lower portion, a first cylindrical upper portion, and a first plurality of ridges, the first plurality of ridges defining a plurality of gaps located between pairs of the first plurality of ridges, and
two electrical contacts, the two electrical contacts of the first electrical connector mechanically and electrically connected to the first plurality of wires;

a first plurality of branches connected to the first trunk segment;
a first light string distributed on the first plurality of branches and in electrical connection with the first plurality of wires; and

a second tree portion, including:
a second trunk segment;
a second plurality of wires;
a second electrical connector positioned at least partially within the second trunk segment, including:
a second connector body, including a second cylindrical portion having a first cavity and a second cavity, and a second plurality of ridges, and
two electrical contacts disposed within the first cavity of the second cylindrical portion, the two electrical contacts of the second electrical connector mechanically and electrically connected to the second plurality of wires;

a second plurality of branches connected to the second trunk segment; and
a second light string distributed on the second plurality of branches and in electrical connection with the second plurality of wires;

a third tree portion including a trunk section, a portion of the trunk section configured to be at least partially disposed within the second cavity,
wherein the first electrical connector is configured to engage mechanically and electrically couple with the second electrical connector, such that each ridge of the second plurality of ridges is located in a gap of the plurality of gaps, thereby limiting rotation of the first electrical connector relative to the second electrical connector and also limiting rotation of the first tree portion relative to the second tree portion.
