8 . The wire guide assembly of claim 1 , wherein the seal comprises a ribbed circumferential exterior sealing surface.
9 . The wire guide assembly of claim 1 , wherein the at least one seal wire opening is closed in the axial direction via flashing.
10 . The wire guide assembly of claim 1 , wherein the seal cover includes a latch adapted to engage with a corresponding catch of an electronics device housing.
11 . An electrical assembly, comprising:
an electrical device having a body defining a wire opening;
a wire guide assembly at least partially insertable into the wire opening of the electrical device and including:
a cover selectively fixable to the body over the wire opening, and defining a wire opening sized to receive a wire;
a guide arranged in the wire opening of the electrical device and having a wire opening a sized to receive the wire; and
a seal arranged in the wire opening of the electrical device and positioned between and completely separating the cover and the guide, and defining a wire opening sized to receive the wire, the cover defines a first face, a first axially facing side of the seal opposingly abuts the first face of the cover and a second axially facing side of the seal opposite the first axially facing side of the seal opposingly abuts the guide.
12 . The electrical assembly of claim 11 , wherein the cover and the guide are fixedly attached to the seal.
13 . The electrical assembly of claim 11 , wherein the wire opening of the seal defines a plurality of internal sealing ribs each sized to form a seal with an outer insulation of the wire passing therethrough.
14 . The electrical assembly of claim 11 , wherein the seal cover includes a hollow guide post coaxially aligned with the wire opening of the cover and extending into the wire opening of the seal.
15 . A charging inlet for an electric vehicle, comprising:
a body for housing at least one conductive terminal, the body including at least one inlet opening;
a wire inserted through the inlet opening of the body; and
a wire guide assembly receiving the wire and inserted through the inlet opening of the body, including:
a seal cover removably attached to the at least one inlet opening and including a cover wire opening defined therethrough and receiving the wire;
a strain relief guide defining a guide wire opening aligned with the cover opening and receiving the wire; and
a seal arranged between and completely separating the seal cover and the strain relief guide and defining at a seal wire opening aligned with the cover opening and the guide opening in the axial direction, the seal opening receiving the wire and forming a seal therewith, the seal cover defines a first face, a first axially facing side of the seal opposingly abuts the first face of the seal cover and a second axially facing side of the seal opposite the first axially facing side of the seal opposingly abuts the strain relief guide.
16 . The charging inlet of claim 15 , wherein the seal wire opening defines a plurality of internal sealing ribs, each rib sized to form a seal with an outer insulation of the wire passing therethrough.
17 . The charging inlet of claim 15 , wherein the strain relief guide includes an alignment protrusion extending from an end thereof opposite the seal and engaging with the body for fixing the axial position of the wire guide assembly.
18 . The charging inlet of claim 15 , wherein the cover defines a hollow post extending from the cover opening in a direction of the seal, the post extending partially through the seal with the seal fitted to the cover.
