DETAILED DESCRIPTION

(8) Various embodiments will be described hereinafter with reference to the accompanying drawings.

(9) As illustrated in FIGS. 1 to 3, and 6, a cable cover 10 according to an embodiment is attached to a side of a rear surface 21a of a female housing (housing) 21 of a female connector (connector) 20, and covers a cable 30 pulled out from the rear surface 21a. The cable cover 10 includes a main body cover 11 made of a synthetic resin and having a substantially semi-cylindrical shape, a lid cover 14 made of a synthetic resin and having a substantially semi-cylindrical shape, and a hinge 18 made of a synthetic resin and coupling the main body cover 11 and the lid cover 14. The main body cover 11 is attached to recessed cover locking grooves 22 each provided on respective side surfaces 21b of the female housing 21. The lid cover 14 is attached to a cover attachment protrusion 23 provided on a lower surface 21c of the female housing 21 in a state of being combined with the main body cover 11 into a tubular shape, and covers a front end side of a corrugated tube 32 through which the cables 30 penetrate.

(10) A pair of attachment portions 12 is integrally formed on a front side of the main body cover 11 in such a manner as to be vertically extend in parallel. On an inner side of each of the attachment portions 12, a housing locking protrusion 12a formed in a protruded shaped is provided as a housing locking portion fitted into a corresponding cover locking groove 22. On an inner surface of the main body cover 11, a recessed portion (not illustrated) locked to a bellows-like protruded portion 32a of the corrugated tube 32 is provided. A lock hole 13 is provided at an end portion, on an opposite side of the hinge 18, of the main body cover 11.

(11) As illustrated in FIG. 5, on a front side of an inner surface of the lid cover 14, a recessed housing attachment groove 15 is provided as a housing attachment portion into which the cover attachment protrusion 23 of the female housing 21 is fitted. Also, a recessed portion (not illustrated) locked to the bellows-like protruded portion 32a of the corrugated tube 32 is provided on the inner surface of the lid cover 14. As illustrated in FIG. 1, a lock protrusion portion 16 locked into the lock hole 13 is provided at an end portion, on an opposite side of the hinge 18, of the lid cover 14. As illustrated in FIGS. 3 and 6, a protrusion portion 17a of a lock arm 17 locked to the lock protrusion portion 13a of the main body cover 11 is provided at an end portion, on a side of the hinge 18, of the lid cover 14. When the main body cover 11 and the lid cover 14 are combined into a tubular shape, a step portion 15b formed in a front portion on an outer side of the lid cover 14 is fitted into a notch portion 12b formed on a side of a lower end of the attachment portion 12 on an outer side of the main body cover 11.

(12) As illustrated in FIG. 4A, the hinge 18 is integrally formed at facing end portions of the main body cover 11 and the lid cover 14. Also, the hinge 18 has a central portion 18b formed thinner than a root portion 18a of the main body cover 11 and a root portion 18a of the lid cover 14, and is formed in an arc surface shape curved upward as a whole. That is, in the hinge 18, the central portion 18b is curved in a bending direction of combining the main body cover 11 and the lid cover 14.

(13) As illustrated in FIG. 6, the recessed cover locking groove 22 as a cover locking portion is formed on a rear end side of each of the side surfaces 21b of the female housing 21. As illustrated in FIG. 5, the cover attachment protrusion 23 as a cover attachment portion is provided at a rear end of the lower surface 21c of the female housing 21.

(14) As illustrated in FIGS. 2, 5, and 6, the female housing 21 includes two terminal housing chambers (not illustrated) in which female terminals (terminal) 31 connected to the cables 30 are housed. Also, at a center of the female housing 21, a hood portion 24 having an opened front surface side and upper surface side into which a male housing (not illustrated) of a male connector (not illustrated) on an opposite side is fitted, and a tubular cap (sub-housing) 25 that is fitted into a front side and that has a terminal insertion hole 25a, into which a male terminal (not illustrated) on an opposite side is inserted, and a lance 25b to lock the female terminal 31 are provided.

(15) As illustrated in FIG. 2, a lock arm 26 to lock a fitted state with respect to a male connector on the opposite side is provided in the hood portion 24 on a ceiling surface side of the female housing 21. An operation end 26a of the lock arm 26 is provided on a rear side of the upper surface opening of the hood portion 24.

(16) With the cable cover 10 according to the embodiment, the hinge 18 that couples the main body cover 11 and the lid cover 14 is not straight but is in an arc manner, whereby a thin part of the central portion 18b of the hinge 18 is bent when the lid cover 14 is rotated, closed, and assembled with respect to the main body cover 11. Thus, assembly of the main body cover 11 and the lid cover 14 becomes easy. Also, since the hinge 18 is thinned from the root portion 18a of the main body cover 11 and the root portion 18a of the lid cover 14 toward the central portion 18b, bending becomes easier and assembly of the cable cover 10 is improved.

(17) FIG. 4B is an enlarged front view of a hinge 18′ that is a modification example of the embodiment and that couples a main body cover 11 and a lid cover 14.

(18) In the hinge 18′ of the modification example of the embodiment, a central portion 18b is formed thinner than a root portion 18a of the main body cover 11 and a root portion 18a of the lid cover 14. Moreover, in the hinge 18′, an inner surface of the central portion 18b on an inner peripheral side in a bending direction of combining the main body cover 11 and the lid cover 14 is formed as an arc surface 18c, and an outer surface of the central portion 18b on an outer peripheral side is formed as a straight surface 18d.

(19) Similarly to the hinge 18 of the embodiment illustrated in FIG. 4A, in the hinge 18′ of the modification example of the embodiment, the inner surface on the inner peripheral side in the bending direction of the central portion 18b is also the arc surface 18c curved upward. Thus, a function and an effect of the hinge 18′ of the modification example of the embodiment similar to those in a case of the hinge 18 of the embodiment illustrated in FIG. 4A are acquired.
