Description

  The present invention relates to a protector for protecting an electric wire, and more particularly to a protector suitable for packaging a wire harness for a vehicle.

  In a wire harness mounted on a vehicle, in many cases, a wire is covered and protected by a synthetic resin protector in a part of the wiring section. Such a protector is composed of a protector body having a concave cross section and a lid member, and the protector body and the lid member are generally held in a closed state by a snap lock type locking mechanism.

As a conventional protector of this type, for example, one as shown in FIG. 7 is known.
The protector 100 shown in the figure protrudes toward the wire housing groove 103 so as to approach each other on the upper side of the side walls 111 and 112 of the protector main body 101 inward from the lid portion 102 closing the upper part of the protector main body 101. A plurality of pairs of hook-shaped wire locking plates 113 and 114 are provided to prevent the wire W from protruding from the wire housing groove 103 before the lid 102 is attached (see, for example, Patent Document 1).

JP, 2009-268163, A (Drawing 7, paragraph 0006)

  However, in the above-described conventional protector, a plurality of pairs of wire locking plates 113, 114 face each other in the groove width direction of the wire housing groove 103, and their tips projecting into the wire housing groove 103 receive the wire. The groove 103 is configured to be close in the groove width direction. Therefore, the workability of the work of housing the electric wire W in the electric wire housing groove 103 is deteriorated, and in particular, the number of installed wire locking plates 113 and 114 is set to securely control the protrusion of the electric wire W from the electric wire housing groove 103. If it is increased, there is a problem that the workability of the wire accommodation work becomes very bad.

  Further, since the wire locking plates 113 and 114 are configured to set the flexible arm length long so that the base end portions thereof are positioned on the inner bottom wall side of the protector main body 101, the wire locking plates 113 and 114 protrude from the wire housing groove 103. Even if the electric wire W is caught between the electric wire locking plates 113 and 114 and the lid portion 102, not only the lid portion 102 may be easily locked, but also the presence or absence of such electric wire W biting There was a problem that it was impossible to do.

  The present invention has been made to solve such conventional unsolved problems, and provides a protector that is excellent in the workability of housing the wire and can easily confirm the presence or absence of the wire protruding from the wire housing groove. The purpose is to

  In order to achieve the above object, the protector according to the present invention can be pivoted in the opening / closing direction to one of the side walls of a protector body having a wire receiving groove for receiving a wire and both side walls of the wire receiving groove of the protector body. It is supported and provided in the vicinity of the other side wall of the lid member that closes the wire housing groove at the time of closing and the other side wall of both side walls of the wire housing groove, and the lid member is turned to a predetermined position in the closing direction. When the protector is provided with a lock mechanism for holding the lid member in the closed state, the protrusion projecting upward from the upper portion of the other side wall of the wire receiving groove is provided. An abutment portion which can abut against the upper portion of the other side wall at the time of closing, and the lid member in the vicinity of an end of the abutment portion on the electric wire receiving groove side, and the protrusion at the time of closing And an accommodation hole for accommodating It is, when the part in the abutment when the closure reaches the vicinity of a position butting abuts against the upper portion of the other side wall, characterized in that locking of the locking mechanism according.

  With this configuration, in the present invention, when the lid member is closed, the abutting portion abuts on the upper portion of the other side wall of the wire receiving groove, and from the other side wall near the end portion on the wire receiving groove side of the abutting portion. A protrusion projecting upward is accommodated in the accommodation hole of the lid member.

  When the lid member is closed, if part of the electric wire in the electric wire housing groove protrudes to the upper side of the other side wall which is the lock mechanism side, the part of the protruding electric wire is the protrusion and the other side wall. By being held on the upper side of the lock mechanism by the upper part, the lock of the lock mechanism is not released. Moreover, the protrusion height of the protrusion accommodated in the accommodation hole decreases or the protrusion disappears, so that the protrusion state of the electric wire can be visually confirmed easily and accurately. Furthermore, since the projection protrudes upward instead of the inner side of the wire housing groove in the groove width direction, the entrance width of the wire housing groove is not greatly narrowed, and the wire housing groove before the lid member is closed. Workability of the wire accommodation work inside improves.

  When the abutment portion reaches the vicinity of the abutment position where the abutment portion abuts on the upper portion of the other side wall, the abutment portion of the lid member passes through the electric wire biting height region in the upper portion of the other side wall This means, for example, when approaching the abutment position side that abuts the upper part of the other side wall than the predetermined wire biting height assumed when biting the wire of the smallest diameter.

In the protector of the present invention, furthermore, with recesses corresponding to the protruding support part above the butting part of the lid member is formed, and the accommodation hole portion on the inner surface side of the concave portion is open, The protrusion accommodated in the accommodation hole at the time of closing is configured to project into the recess .

  Further, in the protector of the present invention, the protector main body protrudes from the one side wall into the wire receiving groove on the upper side of the one side wall of the wire receiving groove, and the wire protrudes from the wire receiving groove And the rib member which projects into the wire receiving groove to the same height as the laterally facing protrusion while being close to the upper portion of the one side wall of the wire receiving groove. It may have a configuration.

  Furthermore, in the protector according to the present invention, the protector main body extends from the vicinity of the protrusion into the wire receiving groove, and is an inclined guide separating from the inner wall surface of the other side wall as entering the wire receiving groove from the protrusion. It may have a face.

  ADVANTAGE OF THE INVENTION According to this invention, while it is excellent in the accommodation workability of an electric wire, the protector which can confirm easily the presence or absence of the protrusion of the electric wire from a wire storage groove can be provided.

And the lid member 13 is in close proximity to the upper portion of the side wall 22 of the wire receiving groove 11 while the wire height h is the same as that of the plurality of laterally facing protrusion portions 29. It has a downward rib 36 projecting into the groove 11. Therefore, as described above, when the lid member 13 is closed, it is difficult for the electric wire W to protrude onto the sideward projecting piece portion 29, and temporarily the electric wire W is inserted between any of the sideways projecting piece portion 29 and the lid member 13. Even if the protrusion is generated, the protrusion state can be easily visually confirmed through the notch recess 37, and the biting of the electric wire W can be accurately prevented in advance.

  Further, in the present embodiment, the protector main body 12 extends from the vicinity of the protrusion 27 into the wire receiving groove 11 and is inclined away from the inner wall surface 23 a of the other side wall 23 as entering the wire receiving groove 11 from the protrusion 27. Since 28a is provided, the wire accommodation work from the other side wall 23 side into the wire accommodation groove 11 is facilitated, and the protrusion of the electric wire W to the other side wall 23 side can be effectively suppressed. .

  Thus, according to the present embodiment, it is possible to provide the protector 10 that is excellent in the workability of housing the electric wires W1 to W5 and can easily check the presence or absence of the protrusion of the electric wire W from the electric wire housing groove 11.
