[0009] Hereinafter, the connector cover according to the present embodiment will be described in detail with reference to the drawings. Note that the dimensional ratios in the drawings are exaggerated for the convenience of explanation and may differ from the actual ratios.
[0010] As shown in Figs. 1 to 3, a connector cover 10 according to this embodiment is attached to the wire pull-out side of a connector (not shown). The wire is protected by being inserted through a corrugated tube 60, which is a cylindrical protective member. The corrugated tube 60 is made of a synthetic resin tube, and has a plurality of ridges 61 and valleys 62 formed around the circumference and alternately arranged in the axial direction. An end of the corrugated tube 60 is engaged and held by the connector cover 10. As a result, the connector and the corrugated tube 60 are connected by the connector cover 10, and the wire pulled out from the connector is covered and protected by the connector cover 10 between the connector and the corrugated tube 60.
[0011] The connector cover 10 includes a first cover 11 and a second cover 12. The first cover 11 and the second cover 12 are connected to each other by a locking portion 13. The first cover 11 and the second cover 12 are each formed of a synthetic resin. The connector cover 10 is assembled in a state in which the first cover 11 and the second cover 12 are butted against each other. In this connector cover 10, the butted position of the first cover 11 and the second cover 12 is set to a radial center position of the corrugated tube 60 that is held. The first cover 11 and the second cover 12 are rotatably connected to each other by a hinge portion, and the first cover 11, the second cover 12, and the hinge portion may be integrally molded from a synthetic resin.
[0012] The first cover 11 has a male lock portion 21 and a female lock portion 23 that constitute the lock portion 13 on both sides in the width direction. The male lock portion 21 has a locking piece 22. The male lock portion 21 of the first cover 11 is locked to a female lock portion 43 of the second cover 12, which will be described later, by the locking piece 22. On the other hand, the male lock portion 41 of the second cover 12, which will be described later, is locked to the female lock portion 23 of the first cover 11 by the locking piece 42. In this way, the first cover 11 and the second cover 12 are connected to each other by the lock portion 13.
[0013] The second cover 12 has a male lock portion 41 and a female lock portion 43 that constitute the lock portion 13 on both sides in the width direction. The male lock portion 41 has a locking piece 42. The male lock portion 41 of the second cover 12 is locked to the female lock portion 23 of the first cover 11 by the locking piece 42. On the other hand, the male lock portion 21 of the first cover 11 is locked to the female lock portion 43 of the second cover 12 by the locking piece 22. As a result, the first cover 11 and the second cover 12 are connected to each other by the lock portion 13.
[0014] As shown in Figs. 4 to 6, the first cover 11 has a holding portion 24 for holding the corrugated tube 60 at one end side in the drawing direction of the electric wire. The holding portion 24 is formed on the side of the first cover 11 where the first cover 11 butts against the second cover 12, and has a holding groove portion 25 that is recessed in an arc shape in cross section. A plurality of locking ridges 26 are formed on the inner surface of the holding groove portion 25. The locking ridges 26 are arranged at equal intervals. The locking ridges 26 are arranged at the same arrangement pitch P as the pitch Pc of the valley portions 62 of the corrugated tube 60 (see Fig. 3). An end of the corrugated tube 60 is arranged in the holding groove portion 25. When the corrugated tube 60 is arranged at a predetermined position in the holding groove portion 25, the locking ridges 26 fit into the valley portions 62 of the corrugated tube 60, and the end of the corrugated tube 60 is held in the holding groove portion 25.
[0015] Furthermore, a wall portion (wire restriction wall 27) is provided on the side of the first cover 11 where it butts against the second cover 12, and is formed along the width direction perpendicular to the direction in which the wires are drawn out. The wire restriction wall 27 has a wire accommodating recess 28 in the center in the width direction. The wire accommodating recess 28 accommodates the wires drawn out from the connector. The wire restriction wall 27 is formed at a position spaced from the adjacent locking protrusions 26 by a distance G larger than the pitch Pc of the valley portions 62 of the corrugated tube 60 (see FIG. 3). The wire restriction wall 27 has a thickness T smaller than the pitch Pm of the peak portions 61 of the corrugated tube 60 (see FIG. 3).
[0016] The first cover 11 has a locking portion 31 for locking the connector at the other end side in the wire drawing direction. This locking portion 31 has a locking groove 32, and by inserting a locking piece (not shown) of the connector into this locking groove 32, the locking piece of the connector is locked by the locking groove 32. In this way, the first cover 11 is assembled to the connector.
[0017] As shown in FIG. 3 and FIG. 8, the second cover 12 has a holding portion 44 for holding the corrugated tube 60 at one end side in the drawing direction of the electric wire. The holding portion 44 is formed on the side of the second cover 12 where the second cover 12 butts against the first cover 11, and has a holding groove portion 45 that is recessed in an arc shape in a cross section. A plurality of locking ridges 46 are formed on the inner surface of the holding groove portion 45. The locking ridges 46 are arranged at equal intervals. The locking ridges 46 are arranged at the same arrangement pitch P as the pitch Pc of the valley portions 62 of the corrugated tube 60, similar to the locking ridges 26 formed in the holding groove portion 25 of the first cover 11. The end of the corrugated tube 60 is arranged in the holding groove portion 45. When the corrugated tube 60 is arranged at a predetermined position in the holding groove portion 45, the locking ridges 46 enter the valley portions 62 of the corrugated tube 60, and the end of the corrugated tube 60 is held in the holding groove portion 45. The ends of the corrugated tube 60 are locked by the locking protrusions 26, 46 when the first cover 11 and the second cover 12 are butted together.
[0018] Further, a wall portion (wire restriction wall 47) is formed along a width direction perpendicular to the wire drawing direction on the side where the second cover 12 butts against the first cover 11 and protrudes therefrom. The wire restriction wall 47 has a wire accommodating recess 48 at the center in the width direction. The wire restriction wall 47 is formed at a position facing the wire restriction wall 27 of the first cover 11 and abuts against the wire restriction wall 27. When the wire restriction walls 27, 47 abut against each other, the wire accommodating recesses 28, 48 of the wire restriction walls 27, 47 form the hole portion 14 through which the wire is inserted (see FIG. 3). The wire restriction wall 47 is formed at a position with a gap G larger than the pitch Pc of the valley portions 62 of the corrugated tube 60 from the adjacent locking protrusions 46. The wire restriction wall 47 also has a thickness T smaller than the pitch Pm of the peak portions 61 of the corrugated tube 60.
[0019] The second cover 12 has a locking portion 51 for locking the connector at the other end side in the wire drawing direction. This locking portion 51 has a locking groove 52, and by inserting a locking piece (not shown) of the connector into this locking groove 52, the locking piece of the connector is locked by the locking groove 52. In this way, the second cover 12 is assembled to the connector.
[0020] As shown in Fig. 4 to Fig. 6, the wire regulating wall 27 of the first cover 11 is formed with a protrusion 29 that protrudes toward the holding portion 24 in the wire drawing direction. This protrusion 29 protrudes from the bottom of the wire accommodating recess 28 formed in the first cover 11. That is, the wire accommodating recesses 28, 48 of the first cover 11 and the second cover 12 form a hole 14 through which the wire is inserted, and the protrusion 29 protrudes from the periphery of the hole 14. It is preferable that the protrusion length L of the protrusion 29 from the wire regulating wall 27 is smaller than the interval G between the wire regulating wall 27 and the adjacent locking protrusion 26 (see Fig. 3). In addition, the lower surface 29a of the protrusion 29 may be formed into a curved surface having the same curvature as the curvature of the inner circumference of the corrugated tube 60.
[0021] Next, the case where the connector cover 10 is attached to the corrugated tube 60 will be described.
[0022] First, the corrugated tube 60 is placed (temporarily placed) on the first cover 11 of the connector cover 10. Specifically, as shown in FIG. 7, a lower end portion of the corrugated tube 60 is inserted under the protrusion 29 protruding from the electric wire regulating wall 27 of the first cover 11, and the end portion of the corrugated tube 60 is abutted against the electric wire regulating wall 27. In this manner, the corrugated tube 60 is positioned in the axial direction with respect to the first cover 11. From this state, the corrugated tube 60 is inserted into the holding groove 25 of the first cover 11. Then, as shown in FIG. 8, the locking protrusion 26 of the holding groove 25 is inserted into the valley 62 of the corrugated tube 60, and the end portion of the corrugated tube 60 is held in the holding groove 25.
[0023] Furthermore, by forming the protrusions 29 on the electric wire regulating walls 27 of the first cover 11, the corrugated tube 60 can be temporarily fixed to the first cover 11, thereby preventing it from falling off. That is, by forming the protrusions 29 on the electric wire regulating walls 27 of the first cover 11, the end of the corrugated tube 60 is caught and locked by the protrusions 29, and the corrugated tube 60 can be temporarily fixed to the first cover 11. This makes it possible to smoothly attach the connector and the corrugated tube 60 to the connector cover 10 without the corrugated tube 60 falling off from the first cover 11 of the connector cover 10 during the attachment work.
[0024] Thereafter, as shown in FIG. 3, the second cover 12 is butted against the first cover 11 which is attached to the connector and to which the corrugated tube 60 is engaged.
[0025] Then, the first cover 11 and the second cover 12 are locked to each other by the locking portion 13. Then, the electric wire regulating wall 47 of the second cover 12 is abutted against the electric wire regulating wall 27 of the first cover 11. As a result, the hole portion 14 is formed by the electric wire accommodating recesses 28, 48 of the electric wire regulating walls 27, 47 of the first cover 11 and the second cover 12, and the electric wire is held in a state of being inserted through the hole portion 14. Also, the corrugated tube 60 enters the holding groove portion 45 of the second cover 12. As a result, the locking protrusions 46 of the holding groove portion 45 enter the valley portions 62 of the corrugated tube 60, and the end portion of the corrugated tube 60 is locked to and held in the holding groove portions 25, 45 of the first cover 11 and the second cover 12.
[0026] In this manner, by attaching the connector cover 10 to the connector and the corrugated tube 60, the connector cover 10 can connect the connector and the corrugated tube 60 and cover and protect the electric wires drawn out from the connector.
[0027] Thus, the connector cover 10 according to the embodiment is attached to the connector and the cylindrical protective member (corrugated tube 60) through which the electric wires drawn out from the connector are inserted, and covers the electric wires drawn out from the connector. The connector cover 10 includes a pair of covers (first cover 11, second cover 12) that are butted against each other to sandwich and connect the connector and the protective member (corrugated tube 60). Each of the pair of covers (first cover 11, second cover 12) has a locking portion 31, 51 that locks the connector and a holding portion 24, 44 that holds the protective member (corrugated tube 60). Each of the pair of covers (first cover 11, second cover 12) has a wall portion (electric wire regulating wall 27, 47) that is formed between the locking portion 31, 51 and the holding portion 24, 44 and faces an end of the protective member (corrugated tube 60). The pair of covers (first cover 11, second cover 12) each have a wire accommodating recess 28, 48 formed in the center of the width direction perpendicular to the wire pull-out direction in the wall portion (wire restriction wall 27, 47) for accommodating the wire pulled out from the connector. A protrusion 29 that protrudes toward the holding portion 24 side along the wire pull-out direction is formed on the wall portion (wire restriction wall 27) of one cover (first cover 11) of the pair of covers (first cover 11, second cover 12).
[0028] By forming the protrusions 29 on the electric wire regulating walls 27 of the first cover 11, the corrugated tube 60 can be temporarily fixed to the first cover 11, thereby preventing it from falling off. That is, by forming the protrusions 29 on the electric wire regulating walls 27 of the first cover 11, the end of the corrugated tube 60 is caught and locked by the protrusions 29, and the corrugated tube 60 can be temporarily fixed to the first cover 11. This makes it possible to smoothly attach the connector and the corrugated tube 60 to the connector cover 10 without the corrugated tube 60 falling off from the first cover 11 of the connector cover 10 during the attachment work.
[0029] As described above, according to this embodiment, during the work of attaching the connector and the corrugated tube 60 to the connector cover 10, the corrugated tube 60 can be temporarily fastened to the first cover 11, thereby preventing the corrugated tube 60 from falling off.
[0030] In the connector cover 10, the protrusion 29 protrudes from the bottom of the electric wire accommodating recess 28 formed in one of the covers (the first cover 11).
[0031] By forming the protrusions 29 in this manner, the end of the corrugated tube 60 is caught and locked on the protrusions 29, and the corrugated tube 60 can be temporarily fixed to the first cover 11.
[0032] In the connector cover 10, the wire accommodating recesses 28, 48 of the pair of covers (first cover 11, second cover 12) form the hole 14 through which the electric wire is inserted, and the protrusion 29 protrudes from the periphery of the hole 14.
[0033] By forming the protrusions 29 in this manner, the end of the corrugated tube 60 is caught and locked on the protrusions 29, and the corrugated tube 60 can be temporarily fixed to the first cover 11.
[0034] Although the present embodiment has been described above, the present embodiment is not limited to this, and various modifications are possible within the scope of the gist of the present embodiment. [Explanation of symbols]
