Electric wire holding device and wire harness

摘要

An electric wire holding device is composed of an electric wire holding member made of a resin to hold an electric wire, a cylindrical member made of an electrically conductive metal, including an inner surface to be mated around and receive at least a mating portion of the electric wire holding member, and a plurality of protrusions formed around an outer circumference of the at least mating portion of the electric wire holding member for the cylindrical member to be mated therearound. The plurality of protrusions are brought into contact with the inner surface of the cylindrical member.

主权项

1. An electric wire holding device, comprising: an electric wire holding member made of a resin to hold an electric wire; a cylindrical member made of an electrically conductive metal, including a continuous inner surface to be mated around and receive at least a mating portion of the electric wire holding member; a sealing member arranged side by side with the cylindrical member in a longitudinal direction of the electric wire; a seal holding portion, the sealing member being held around an outer circumference of the seal holding portion; a plurality of protrusions formed around an outer circumference of the at least mating portion of the electric wire holding member for the cylindrical member to be mated therearound, the plurality of protrusions to be brought into contact with the inner surface of the cylindrical member, and a wall formed around an outer circumference of the mating portion around the sealing member side outer circumference of the electric wire holding member relative to the plurality of protrusions around the at least mating portion, the wall being lower in protrusion height than the plurality of protrusions but higher in protrusion height than an outer circumferential surface of the mating portion, wherein a distance between an outer circumference of the wall and the electric wire is longer than a distance between an outer circumference of the seal holding portion and the electric wire, wherein the protrusions resiliently deform against the continuous inner surface of the cylindrical member, and wherein a protruding direction of the wall of the electric wire holding member is the same as a protruding direction of the protrusions, and the wall is formed between the sealing member and the protrusions in a ring shape so as to circumscribe an outer circumference of the at least mating portion.
