Description

  The present invention relates to a protector that externally covers a group of wires such as a wire harness routed in an automobile.

  In the case of a wire group such as a wire harness that is routed in an automobile, when there is a part that protects the wire group and restricts the wiring direction, the wire group is inserted into the protector at that point. In addition, when a protector has a bending part, the electric wire group in a protector may not crawl along a bending part, and an electric wire group may protrude from the inside of a protector and may prevent fitting of a cover.

  It is assumed that such a wire group is prevented from protruding from the protector, for example, a protector shown in Patent Document 1 is known.

  That is, the protector shown in Patent Document 1 is provided with a lock frame portion 42 and a cover lock frame portion 43 on the upper edge portion of the side wall 41 of the protector main body 40 as shown in FIG. An electric wire pressing piece 46 having a lock claw 45 projecting from one side wall 41 is provided in the vicinity of the lower side (the bent point lowest point) of the 40 bent portions 44. The electric wire pressing piece 46 suppresses the lifting of the electric wire group W.

  As shown in FIG. 7B, the wire pressing piece 46 is tilted so as to be bridged from one side wall 41 to the other side wall 41, and the lock claw 45 is locked to the lock frame portion 42. Then, as shown in FIG. 7C, the interior of the protector body 40 is closed by the lock claw 51 of the cover 50 being engaged with the cover lock frame portion 43.

Further, the support portion 32 of the hinge 30 on the side wall 12 a side and the lock frame portion 15 on the side wall 12 b side are inclined without being orthogonal to the longitudinal direction of the protector body 10. In other words, the lines connecting the respective lock positions intersect.

  More specifically, at the boundary portion of the bent portion 13 (bent portion lowermost point A), the wire group (not shown) is most strongly lifted, but the portion where the lift is most strong is locked by the lock claw 31 of the hinge 30. The cover 20 can be surely pressed by being locked by a lock claw 22 described later.

  The cover 20 has an upper wall 21 that closes the entire upper surface opening of the protector body 10. A plurality of lock claws 22 project downward from both side edges of the upper wall 21 in the width direction. These lock claws 22 are arranged at positions corresponding to the lock frame portion 14 of the protector body 10. When the cover 20 is attached to the protector body 10, each lock claw 22 is locked to each lock frame portion 14 of the protector body 10.

  Next, an operation procedure for attaching the protector 1 to a wire group (not shown) will be described. First, as shown in FIG. 4, with the hinge 30 opened, the protector body 10 is attached to a wire group (not shown).

  Thereafter, as shown in FIG. 6, the cover 20 is put on the upper surface opening of the protector main body 10, and the respective lock claws 22 of the cover 20 are engaged with the respective lock frame portions 14 of the protector main body 10.

  At this time, as described above, in particular, at the boundary portion (the bent portion lowest point A) of the bent portion 13 of the protector body 10, the lock frame portion 14 on the side wall 12a side, the lock frame portion 14 on the side wall 12b side, Are arranged so as to be inclined without being orthogonal to the longitudinal direction of the protector body 10. Further, the support portion 32 of the hinge 30 on the side wall 12 a side and the lock frame portion 15 on the side wall 12 b side are arranged so as to be inclined without being orthogonal to the longitudinal direction of the protector body 10. In other words, the lines connecting the respective lock positions intersect.

  As a result, when the cover 20 is attached to the protector body 10, as shown in FIG. 6, the lock frame on the side wall 12 a side is formed at the boundary portion (bending portion lowest point A) of the bent portion 13 of the protector body 10. As shown by a line (dotted line y) connecting the portion 14 and the lock frame portion 15 on the side wall 12b side, a group of wires (not shown) is pressed so as to be orthogonal in the longitudinal direction.

  As described above, in the present embodiment, the other end side of the hinge 30 that is foldably supported by the support portion 32 is bent toward the other side wall 12b, and the lock claw 31 on the one end side is bent to the other side wall. It is made to latch on the lock frame part 15 which is the 1st latching | locking part provided in the boundary part (bending part lowest point A) of the bending part 13 of 12b.

  As a result, the locking claw 31 of the hinge 30 is locked to the lock frame portion 15 that is the first locking portion at the boundary portion (bending portion lowest point A) of the bending portion 13, and is not shown. The part where the lifting force of the electric wire group becomes the strongest can be surely pressed down.

  In other words, at the boundary portion (bending portion lowest point A) of the bent portion 13, the wire group (not shown) has the strongest lifting, but the portion with the strongest lifting is the support portion 32 on the other end side of the hinge 30. And the lock frame portion 15 that is the first locking portion to which the lock claw 31 of the hinge 30 is locked.

  Further, a lock frame portion 14 as a second locking portion is provided at the boundary portion (bending portion lowest point A) of the bending portion 13 of one side wall 12a, and the boundary portion (bending portion of the bending portion 13 of the other side wall 12b is bent. By providing the lock frame portion 14 as the third locking portion in the vicinity of the lowest point A), the first locking portion lock frame portion 15 and the lock frame portion 14 as the second locking portion, Further, the support portion 32 of the hinge 30 and the lock frame portion 14 which is the third locking portion are arranged at a position orthogonal to the longitudinal direction of the protector body 10, and the lock of the cover 20 is secured to these lock frame portions 14. The claw 22 is further locked.

  In this case, the boundary portion (the bent portion lowest point A) of the bent portion 13 of the protector body 10 is the third locking portion that locks the lock claw 22 of the cover 20, and the lock claw of the hinge 30. Since it is pressed between the lock frame portion 15 which is the first locking portion for locking 31, the cover 20 mounted on the protector body 10 is lifted or deformed against the lifting force of a wire group (not shown). Can be reliably prevented.

  In other words, similarly to the above, at the boundary portion (bent portion lowest point A) of the bent portion 13 of the protector body 10, the wire group (not shown) has the strongest lift, but the portion with the strongest lift is, for example, a hinge Between the lock frame portion 15 that is the first locking portion to which the 30 lock claws 31 are locked and the lock frame portion 14 that is the second locking portion to which the lock claw 22 of the cover 20 is locked. You can hold it down.

  At the boundary portion of the bent portion 13 (the bent portion lowest point A), the lock frame portion 14 on the side wall 12a side and the support portion 32 of the hinge 30 are arranged so as to be reversed, and the lock frame on the side wall 12b side. You may arrange | position the part 15 and the lock frame part 14 so that it may become reverse. In this case, a portion of the electric wire group (not shown) that is most strongly lifted can be pressed between the support portion 32 of the hinge 30 and the lock frame portion 14 to which the lock claw 22 of the cover 20 is locked.

  Further, in the present embodiment, the lock frame portion 14 on the side wall 12a side and the support portion 32 of the hinge 30 are arranged close to each other, and the lock frame portion 15 and the lock frame portion 14 on the side wall 12b side are arranged close to each other, The boundary part (bending part lowest point A) where the floating of the electric wire group (not shown) of the bending part 13 of the protector main body 10 becomes strongest can be pressed in a wide range.

  For example, in addition to those mounted on a group of wires such as a wire harness routed in an automobile, the present invention can also be applied to devices mounted on power lines, signal lines, and the like.
