Description

  The present invention relates to a band clip used when binding a wire harness or the like, or attaching a wire harness or the like to a vehicle body, for example.

  When a wire harness is bundled with a band clip, or when a wire harness is fixed to a vehicle body with a band clip, there is a demand for removing the wire harness later. For example, when the vehicle is disassembled, the wire harness needs to be peeled off from the vehicle body for recycling. At that time, there is a demand for easily removing the wire harness from the band clip.

  Conventionally, Patent Document 1 discloses a band clip as shown in FIG.

  This band clip is provided with a band locking portion 120 having an insertion hole 121 through which the distal end side of a band 110 rolled into a loop shape is inserted at the base end of a band-shaped band 110 made of resin, and the insertion hole 121 is provided with a locking projection (not shown) for locking the band 110, and the band locking portion 120 is provided with an anchor projection 122 for fixing to a mounting hole or the like of the vehicle body panel. ing. Further, in this band clip, a V-shaped dismantling notch 112 serving as a breakage base point is provided on the side edge of the band 110 at a position close to the band locking portion 120.

  When fixing the wire harness to the vehicle body using the band clip, the band 110 is wound around the outer periphery of the wire harness W, and the leading end side of the band 110 is inserted into the insertion hole 121 of the band locking portion 120 and locked. The anchor protrusion 122 is engaged with the mounting hole of the vehicle body panel. Thereby, the wire harness W can be fixed to the vehicle body via the band clip 110.

  Further, in the state where the wire harness W is attached as described above, when it becomes necessary to remove the wire harness W from the band clip due to the dismantling of the vehicle or the like, the wire harness W is pulled as shown by an arrow S in FIG. As a result, stress in the cleavage direction (force in the direction of arrow N) is applied to the dismantling notch 112. By doing so, the band 110 can be cut by cracking with the bottom of the V-shaped dismantling notch 112 as a base point. And thereby, the loop of the band 110 can be unwound and the wire harness W can be removed from the band clip.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a configuration diagram of a band clip according to an embodiment of the present invention, FIG. 2 is an enlarged view thereof, FIG. 3 is a case where the tear line is configured by “grooves”, and FIG. FIGS. 5A and 5B are diagrams illustrating the case where they are configured, and FIG.

  As shown in FIGS. 1 and 2, this band clip has a band hole having an insertion hole 21 through which the distal end side of a band 10 rolled into a loop shape is inserted at the base end of a band-shaped resin band 10. A locking portion 20 is provided, and a locking projection (not shown) for locking the band 10 is provided inside the insertion hole 21, and the band locking portion 20 has a mounting hole in the vehicle body panel. An anchor projection 22 and a skirt portion 23 for fixing are provided.

  The band 10 can be held in a state where the wire harness is bundled (or simply) by being wound around the outer periphery of the wire harness, and on the outer surface (outer surface) when wound around the wire harness. In addition, it has an engagement tooth row (saw-tooth unevenness) 11 that is locked at an arbitrary position by a locking projection in the insertion hole 21 of the band locking portion 20.

  At an arbitrary position in the longitudinal direction of the band 10 (a position close to the band locking portion 20 in FIGS. 1 and 2), the band 10 is located at an intermediate portion in the width direction, A knob 13 is provided. Further, the band 10 is formed with two substantially tear-shaped tear lines 12 extending from the start point 12a to both side edges in the width direction of the band 10 with the vicinity of the knob 13 as a start point 12a. The end of the portion 15 between the two tear lines 12 is continuous with the knob 13.

  These two tear lines 12 are constituted by a weak portion that can be cut and locally weakened compared to other portions of the band 10. For example, as shown in FIG. It is comprised by the groove | channel 22 of the cross-sectional V shape or U-shaped cross section provided in the board surface (this embodiment outer surface). Alternatively, as shown in FIG. 4, the perforations 32 are formed by arranging small holes penetrating in the thickness direction of the band 10 in a row.

  In the case of the V-shaped groove 22, it is preferable to set the angle of the inner surface of the groove with respect to a line perpendicular to the plate surface of the band 10 in the range of 3 to 15 ° in order to improve the tearability. Moreover, when forming the groove | channel 22 in one side, it is preferable to set the depth of the groove | channel 22 in the range of 5%-70% of the thickness of the whole cross section of the part in which the groove | channel 22 was formed.

  An opening 14 that penetrates the band 10 in the thickness direction is provided around the knob 13, and the starting point 12 a of the tear line 12 is set at the edge of the opening 14.

  The band locking portion 20 includes an anchor projection 22 that engages with a panel mounting hole (not shown), and a skirt that presses and contacts the plate surface of the panel when the anchor projection 22 is engaged with the panel mounting hole. A portion 23 is provided. The knob 13 described above is provided at a position of the band 10 on the side of the band locking portion 20, and the C-shaped tear line 12 is provided so as to extend toward the tip side of the band 10.

  When the wire harness is fixed to the vehicle body using the band clip, the band 10 is wound around the outer periphery of the wire harness, and the distal end side of the band 10 is inserted into the insertion hole 21 of the band locking portion 20 and locked. The protrusion 22 is engaged with the mounting hole of the vehicle body panel. Thereby, the wire harness can be fixed to the vehicle body via the band clip 10.

  Further, when it is necessary to remove the wire harness from the band clip when the vehicle is disassembled with the wire harness attached in this manner, the knob 13 is picked by hand, as shown in FIG. 5 (a). Then, the picked portion is strongly pulled in the direction in which the tear line 12 extends (in the direction of arrow A in the figure). Then, as shown in FIG. 5B, the band 10 can be torn along the tear line 12, and the band 10 can be completely broken by further pulling the knob 13 in the direction of the arrow B as it is. . Therefore, the loop of the band 10 can be unwound and the wire harness can be removed from the band 10 of the band clip.

  In this way, since only the knob 13 of the band 10 applies force, even if the wire harness is fixed and does not move, or even if there are obstacles around it, without using a cutting tool or the like. The band 10 can be easily broken and the wire harness can be removed. Further, even if the band clip is assembled to the wire harness at an incorrect position during manufacture, the band 10 can be broken only by pulling the knob 13 strongly, so that the later correspondence can be easily performed.

  In addition, since the opening 14 is provided around the knob 13, the knob 13 can be easily picked with a fingertip, and the work becomes easy. Moreover, since the start point 12a of the tear line 12 is set at the edge of the opening 14, the band 10 is more easily torn.

  Further, when the tear line 12 is constituted by the groove 22, the band 10 can be torn cleanly, and when the tear line 12 is constituted by the perforation 32, the band 10 is torn without reducing the tensile strength. It can be made easier.

  Further, in the case of the band clip of the present embodiment, the knob 13 is provided at the position of the band 10 on the band locking portion 20 side so that the C-shaped tear line 12 extends toward the front end side of the band 10. Since it is provided, it is possible to search for the knob 13 from the side close to the band locking portion 20 in the state of being attached to the vehicle body panel, and it is easy to search even when the knob 13 is not conspicuous. Further, when the band 10 is torn, the direction in which the knob 13 is picked and pulled is away from the panel, so that the band 10 is more easily torn.

  Next, some examples of the shape of the knob 13 are shown using FIG. In terms of ease of picking, it is better that the shape of the knob 13 has a height that protrudes somewhat from the plate surface of the band 10, but if the height is too high, it is likely to get in the way. .

  The knob 13 (13A) in FIG. 6A has a hook shape protruding from the plate surface of the band 10 and is easy to put on a finger. The knob 13 (13B) in FIG. 6B has almost no protrusion height so as not to get in the way. The knob 13 (13C) of FIG. 6C is raised obliquely so as to be slightly lifted from the plate surface of the band 10. Further, the knob 13 (13D) in FIG. 6 (d) has a block shape protruding from the plate surface of the band 10 and is easy to put on a finger.

Next, some examples of the pattern of the tear line 12 are shown using FIG.
The tear line 12 in FIG. 7A is composed of an oblique straight line 12c from the start point 12a to the end point 12b. The tear line 12 in FIG. 7 (b) is composed of a straight line 12d parallel to the side edge of the band 10 from the start point 12a to the middle point toward the end point 12b. It consists of a straight line 12e. The tear line 12 in FIG. 7C is configured by a gentle continuous curved line 12f from the start point 12a to the end point 12b. The tear line 12 in FIG. 7 (d) is composed of a straight line 12g parallel to the side edge of the band 10 from the start point 12a to the middle point toward the end point 12b, and from the middle point to the end point 12b is a curved line. 12h.
