Wire harness

A wire harness comprising:

• a bundle of electric wire members;
• a tubular member surrounding a certain length of the bundle of electric wire members, the tubular member including an axis, a first axial open end, a second axial open end, and a radially inward surface, wherein the bundle of electric wire members includes two ends drawn out from the first and second axial open ends, respectively;
• and
• an electronic wire reception plug fitted in the first axial open end of the tubular member,
• wherein one of the first axial open end of the tubular member and the electronic wire reception plug includes a key groove and the other includes a key protrusion corresponding to the key groove, the key groove and the key protrusion are configured to prevent the electronic wire reception plug from rotating relative to the first axial open end of the tubular member and to define a plugging depth of the electronic wire reception plug relative to the tubular member in the axial direction of the tubular member,
• the electronic wire reception plug includes a radially outward surface corresponding to or being in direct surface contact with the radially inward surface of the tubular member, and a radially inward surface including or forming electronic wire reception grooves configured to receive the electric wire members, respectively.
