Abstract

A wire cover disclosed by this specification is for covering a plurality of wires pulled out from a housing, and includes a cover body into which the plurality of wires pulled out from the housing are introduced from front and from which the plurality of wires are drawn out in a rightward direction, and a guiding portion provided on an inner surface of the cover body and configured to guide small-diameter wires arranged to have shorter in-cover lengths, out of the plurality of wires, than a large-diameter wire on a left side arranged to have a longest in-cover length from a wire introduction position PI where the wire is introduced into the cover body to a wire draw-out position PO where the wire is drawn out from the cover body, out of the plurality of wires to an extra length accommodation space provided in the cover body.

First claim

What is claimed is:

1. A wire cover for covering a plurality of wires pulled out from a housing, comprising:
a cover body into which the plurality of wires pulled out from the housing are introduced and from which the plurality of wires are drawn out in a direction intersecting an introducing direction of the plurality of wires;
an extra length accommodation space provided in the cover body; and
a guiding portion provided on an inner surface of the cover body,
wherein:
if a length from a wire introduction position where the wire is introduced into the cover body to a wire draw-out position where the wire is drawn out from the cover body is an in-cover length, the guiding portion guides at least one wire arranged to have a shorter in-cover length than a reference wire arranged to have a longest in-cover length, out of the plurality of wires, to the extra length accommodation space, and
the at least one wire extends toward a side opposite to the wire draw-out position and is folded 180° to extend toward the wire draw-out position in the extra length accommodation space after being drawn out from the guiding portion.

2. The wire cover of claim 1 , wherein:
the extra length accommodation space in the wire cover is provided on a side opposite to the wire draw-out positions on the basis of the guiding portion, and
the guiding portion includes an oblique portion inclined in a direction different from a direction toward the wire draw-out positions.

3. The wire cover of claim 2 , wherein:
a plurality of the oblique portions are provided to correspond to the respective wires, and
an inclination start position of the oblique portion is more away from the wire introduction position as the oblique portion is located closer to the wire draw-out position.

4. The wire cover of claim 1 , wherein the plurality of wires are pulled out from the wire cover while being covered by an outer coating for collectively covering the plurality of wires and a water sealing member for sealing between the plurality of wires and the outer coating on an end of the outer coating.

5. The wire cover of claim 1 , wherein:
rubber plugs resiliently in close contact with the housing and the wires are externally fit to the wires pulled out from the housing, and
the guiding portion includes a holding portion for holding the wires pulled out from the housing straight in a pull-out direction of the wires.

6. The wire cover of claim 1 , wherein the housing is provided with a locking portion for locking the wire disposed in the extra length accommodation space.

7. A connector with wire cover, comprising:
a housing from which a plurality of wires are pulled; and
the wire cover of claim 1 .

8. A wire cover for covering a plurality of wires pulled out from a housing, comprising:
a cover body into which the plurality of wires pulled out from the housing are introduced and from which the plurality of wires are drawn out in a direction intersecting an introducing direction of the plurality of wires;
an extra length accommodation space provided in the cover body; and
a guiding portion provided on an inner surface of the cover body,
wherein:
if a length from a wire introduction position where the wire is introduced into the cover body to a wire draw-out position where the wire is drawn out from the cover body is an in-cover length, the guiding portion guides at least one wire arranged to have a shorter in-cover length than a reference wire arranged to have a longest in-cover length, out of the plurality of wires, to the extra length accommodation space,
the extra length accommodation space in the wire cover is provided on a side opposite to the wire draw-out positions on the basis of the guiding portion,
the guiding portion includes an oblique portion inclined in a direction different from a direction toward the wire draw-out positions,
a plurality of the oblique portions are provided to correspond to the respective wires, and
an inclination start position of the oblique portion is more away from the wire introduction position as the oblique portion is located closer to the wire draw-out position.

9. The wire cover of claim 8 , wherein the plurality of wires are pulled out from the wire cover while being covered by an outer coating for collectively covering the plurality of wires and a water sealing member for sealing between the plurality of wires and the outer coating on an end of the outer coating.

10. The wire cover of claim 8 , wherein:
rubber plugs resiliently in close contact with the housing and the wires are externally fit to the wires pulled out from the housing, and
the guiding portion includes a holding portion for holding the wires pulled out from the housing straight in a pull-out direction of the wires.

11. The wire cover of claim 8 , wherein the housing is provided with a locking portion for locking the wire disposed in the extra length accommodation space.

12. A connector with wire cover, comprising:
a housing from which a plurality of wires are pulled; and
the wire cover of claim 8 .
