Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In the following description, the direction in which the connector with the wire cover of the embodiment is fitted to the mating connector is the front, the opposite side is the rear, and the direction in which a large number of terminals (not shown) are aligned is the left-right direction And

  As shown in FIG. 1, the connector with an electric wire cover of this embodiment is attached to the connector main body 10 from which the electric wire W is pulled out from the rear to the rear, and the rear of the connector main body 10. An electric wire cover 30 that is led out in a predetermined direction after being bent toward the side (left direction opposite to the mounting side of the lever 20 described later) once, and the right side of the connector main body 10 The lever 20 is mounted at a position so as to be pivotable in the direction of the arrow X, and is pivoted from the right side of the connector main body 10 toward the rear side when mated with the mating connector.

  As shown in FIGS. 1 to 3, the wire cover 30 is divided into a first cover 40 and a second cover 50 in order from the connector body side along the guide direction of the wire W drawn from the rear portion of the connector body 10. Has been.

  The first cover 40 includes a bending direction guide wall 41 having a U-shaped cross section that guides the electric wire W drawn backward from the rear portion of the connector body 10 to be bent sideways. The first cover 40 is configured to fit in a non-interfering space inside the turning locus of the lever 20 for performing the fitting operation with the mating connector.

  The first cover 40 is locked between the one end portion (front end portion) of the first cover 40 and the rear portion of the connector body 10 by sliding the first cover 40 with respect to the rear portion of the connector body 10 in a certain direction. Slide type first lock mechanisms 14 and 44 are provided for detachably connecting one cover 40 and the rear portion of the connector main body 10. The sliding direction when the first cover 40 is locked in this case is a direction toward the side where the electric wire W is bent, that is, a direction from right to left.

  The second cover 50 has a U-shaped lead-out direction in which the electric wire W guided so as to be bent sideways by the bending direction guide wall 41 of the first cover 40 is guided and led out in a predetermined direction. A guide wall 51 is provided. One end portion 53 of the second cover 50 overlaps the other end portion (left end portion) 43 of the first cover 40, and the second cover 50 and the other one of the first cover 40 are interposed therebetween. The slide-type second lock that locks by sliding the end portion 43 from a certain direction and detachably connects the one end portion 53 of the second cover 50 and the other end portion 43 of the first cover 40. Mechanisms 45 and 55 are provided. In this case, the sliding direction when the second cover 50 is locked is a direction from the rear to the front.

  When the electric wire cover 30 is assembled to the connector main body 10, first, the first cover 40 is slid from the right side to the left side as shown by an arrow A as shown in FIG. Then, as shown in FIG. 4, the first lock mechanisms 14 and 44 are engaged with each other, and the first cover 40 is coupled to the connector body 10. Next, the one end portion 53 of the second cover 50 is slid from the rear toward the front as indicated by the arrow B toward the other end portion 43 of the first cover 40. Then, as shown in FIG. 5, the second lock mechanisms 45 and 55 are engaged with each other, and the second cover 50 is coupled to the first cover 40, thereby completing the mounting of the wire cover 30. Next, the lever 20 is attached to the connector main body 10, and the connector is thus completed.

  As described above, the connector with an electric wire cover according to the present embodiment has the first cover 40 with one end attached to the rear portion of the connector main body 10 so that the electric wire W pulled out rearward from the rear portion of the connector main body 10 is immediately on the side. It can be guided to bend toward the direction. Therefore, for example, even when there is an obstacle near the rear of the connector main body 10 and the rear space of the connector main body 10 is limited, the electric wire W drawn from the connector main body 10 can be routed without any trouble.

  Moreover, since it is not necessary to extend the electric wire W behind the connector main body 10, it is applicable also to a connector with a lever like this embodiment. That is, in the case of a connector with a lever, when the connector main body 10 is fitted to the mating connector, for example, the lever 20 needs to be rotated toward the rear of the connector main body 10. Since the electric wire W can be guided to the side so as not to hinder the above, it can be applied to a connector with a lever.

  In the present embodiment, the first cover 40 and the second cover 50 are not formed in a halved structure, but the first cover 40 and the second cover 50 have a U-shaped cross-section guide wall 41 and a lead-out direction guide wall 51 to form the first cover. Since the cover 40 and the second cover 50 are slid and locked in a certain direction, the assembling work is easy. Particularly, since the slide lock direction of the first cover 40 is set to the side and the slide lock direction of the second cover 50 is set to the front side, both the covers 40 and 50 are attached without difficulty while preventing the electric wire W from being caught. be able to.

  Further, the second cover 50 attached to the other end portion 43 of the first cover 40 guides and leads out the electric wire W guided by the first cover 40 so as to be bent sideways in a predetermined direction. can do. In this case, the first cover 40 is interposed in front of the second cover 50 that determines the final lead-out direction of the electric wire W, so that the lead-out directions are arranged from a plurality of types of second covers 50. The second cover 50 suitable for the conditions can be selected and attached freely. Therefore, by preparing only one type of first cover 40 that matches the connector body 10, the first cover 40 can be used in common for a plurality of types of second covers 50, and versatility is improved.

  For example, in the second cover 50 of the above embodiment, the lead-out direction of the electric wire W is set from the side to the front side, but the second covers 50A and 50B in FIGS. 6 (a) and 6 (b). As described above, it may be derived in a direction perpendicular to the bending direction of the first cover 40. In that case, it is only necessary to change the direction of the derivation direction guide walls 51A and 51B. Thus, the final lead-out direction of the electric wire W can be freely switched by selecting the second cover.

  FIG. 7 shows, as a comparative example for the embodiment, an electric wire cover 130 having a shape in which a portion corresponding to the first cover 140 and a portion corresponding to the second cover 150 are integrated is slid from the side and attached to the connector body 10. It shows the state. When the wire cover 130 having an integral structure is used as described above, the slide lock direction of the lock mechanisms 14 and 114 between the rear portion of the connector main body 10 and the end portion of the wire cover 130 is changed to the arrow C direction. The electric wire cover 130 can be attached to the connector main body 10, but depending on the direction of the lead-out direction guide wall 151 of the electric wire W, the electric wire cover 130 cannot be locked only by sliding in a certain direction.

  Therefore, as shown in FIGS. 8 to 10, first, while searching for a position where the electric wire cover 130 can be attached to the connector main body 10 (while aligning the position surrounded by F), the electric wire cover 130 faces the connector main body 10. Then, the electric wire cover 130 is slid sideways (from right to left) with respect to the connector main body 10 from the position shown in FIG.

  Thus, when it is set as the wire cover 130 of an integral structure, there is a high possibility that the assembly is troublesome depending on the difference in the lead-out direction of the wire, but the wire cover 30 and the first cover 40 and the second cover as in the present embodiment. By dividing the cover 50, the trouble of assembling can be reduced.

  In addition, this invention is not limited to embodiment mentioned above, A deformation | transformation, improvement, etc. are possible suitably. In addition, the material, shape, dimensions, number, arrangement location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.
