Description

  The present invention relates to a band clip, and more particularly, to reduce the height of a main body portion that binds and fixes a band wound around a wire group of a wire harness.

Conventionally, resin-molded band clips of various shapes have been used for binding a wire group of a wire harness routed in an automobile or the like and fixing the wire harness to a vehicle body. For example, as shown in FIGS. 6A to 6C, a conventional band clip 100 includes a box-shaped main body 102, a band 105 extending from the main body 102, and a vehicle body that protrudes from the outer surface of the main body 102. A clip 106 that is inserted and locked into the panel hole of the panel is provided.
The main body 102 is provided with an insertion hole 103 through which the band 105 is inserted, and inside the insertion hole 103, a locking claw to be engaged with a serrated locked portion 105a provided on the surface of the inserted band 105. A tongue piece (elastic piece) 104 provided with 104a is projected [see Japanese Patent Application Laid-Open No. 2002-320317 (Patent Document 1)].

  In the band clip 100 having the above-described configuration, as shown in FIG. 6B, the band 105 wound around the wire group 1 is pulled through the insertion hole 103 of the main body 102, and at the band tightening position, as shown in FIG. Thus, the electric wire group 1 is bound by the band 105 by engaging the locked portion 105 a of the band 105 and the locking claw 104 a of the tongue piece 104.

JP 2002-320317 A

  However, the box-shaped main body 102 of the band clip 100 needs to be provided with an insertion hole 103 provided with a tongue piece 104 for locking connection between an upper wall 102a and a lower wall 102b having a predetermined thickness. Therefore, the height H of the main body 102 tends to be large. If the height H of the main body 102 is increased, it is necessary to widen the wiring space of the wire harness, and the center of gravity of the wire harness fixed to the vehicle body becomes high, which may deteriorate the stability. In addition to the lower wall from which the clip 106 protrudes, the main body 102 requires an upper wall and a side wall 102c for forming the insertion hole 103, and there is a problem of weight increase and manufacturing cost increase due to these walls.

  An object of the present invention is to provide a band clip in which the height of a main body for binding and fixing a band wound around a wire group of a wire harness is low, and the weight and material cost can be suppressed.

In order to solve the above-mentioned problem, the present invention is a band clip that is wrapped around a wire harness and fastened to be locked in a mounting hole of a vehicle body panel,
A band-shaped band part in which locking holes are arranged in parallel in the length direction, and a flat band-shaped band locking part and clip mounting part provided by extending one end in the length direction of the band part, A main body in which a screw cylinder having a thread groove provided on the inner peripheral surface thereof is protruded from the band locking portion and clip mounting portion;
A screw shaft portion that is screwed into the screw cylinder of the main body, an annular dish portion that protrudes from the outer periphery of the screw shaft portion, and a locking blade-like locking portion that protrudes from the center of the dish portion are integrally provided. Consisting of clips,
Provided is a band clip configured to be attached to the wire harness by screwing a screw shaft portion of the clip into the screw tube in a state where the screw tube is passed through one of the locking holes of the band portion wound around the wire harness. is doing.

As described above, in the band clip of the present invention, the band locking portion / clip attaching portion provided continuously at one end of the band portion is flat and has a lower height than the conventional box portion. A screw cylinder protrudes from the flat band-like band locking portion and clip mounting portion. The screw tube only needs to have a height that allows the screw shaft portion of a separate clip to be screwed together and to be fitted in the locking hole of the band portion wound around the wire group of the wire harness.
Therefore, the height of the main body can be kept low because there is no need to provide a relatively high insertion hole or upper wall in which a tongue piece for lock coupling projects inward as in the prior art.
Therefore, the wiring harness space can be expanded, and the stability of the wire harness fixed to the vehicle body can be increased. Further, since the upper wall and the side wall in the case of the box-shaped main body are not necessary, it is possible to reduce the weight and the material cost.

  In addition, the band clip of the present invention is configured such that a screw cylinder is passed through one of the locking holes of the band portion wound around the wire harness, and the screw shaft portion of the clip is screwed into the screw cylinder, so that the wire harness is attached to the band clip band. It can be made into the state bundled by the part, and can also be easily attached to the wire harness.

  A clip mounting hole is provided in the band locking portion and clip mounting portion of the main body, a screw groove is provided on an inner peripheral surface of the clip mounting hole, and the screw cylinder is projected from a peripheral edge of the clip mounting hole. It is preferable that an annular small protrusion for prevention of removal is provided on the outer peripheral surface of the protruding end, the annular small protrusion has a V-shaped cross section, and the tip surface has a tapered shape.

  As described above, when the screw tube is provided with an annular small protrusion for retaining, when the screw tube is inserted into the locking hole of the band portion after the band portion of the main body is wound around the wire harness, the main body is temporarily fixed to the wire harness. I can keep it. Since the clip is attached by screwing the screw shaft portion of the clip into the screw cylinder of the main body temporarily fixed to the wire harness, the clip can be easily attached to the main body. In addition, when the tip surface of the annular small protrusion is tapered, the screw cylinder can be easily inserted into the locking hole. In addition, if a clip mounting hole having a thread groove is provided on the inner periphery and a screw cylinder is projected from the peripheral edge, the screw shaft portion can be inserted and screwed to the clip mounting hole, and the height of the screw cylinder can be reduced.

In order to prevent the screw shaft portion from coming off from the screw tube, a locking projection is provided at the tip of the screw groove, while a locking groove portion is provided at the tip of the thread of the screw shaft portion of the clip. It is preferable that an anti-inversion mechanism is provided in contact with the locking protrusion.
When the thread provided on the outer peripheral surface of the male screw thread rod is screwed into the thread groove of the female screw provided on the inner peripheral surface of the screw cylinder, the screw cylinder and the screw rod can be firmly connected. If a locking projection is provided at the tip of the screw groove and a locking groove is provided at the tip of the thread, the screw shaft can be prevented from coming off due to rotation in the direction opposite to the rotation direction.

  The length of the screw shaft portion of the clip is preferably in the range of 2 mm to 4 mm. When the length of the screw shaft portion is the length, the height of the screw cylinder of the main body is 2 mm to 4 mm, and the height of the band locking portion of the band clip can be sufficiently reduced. As a result, it is possible to solve the problem that the wiring harness cannot be routed because the height of the band clip is large in a place where the wiring space of the wire harness is narrow.

  The clip may have a locking shape suitable for the shape of the mounting hole of the vehicle body as long as the clip has a shape with a screw shaft portion that is screwed into the screw cylinder. For example, a shape in which a pair of blade portions project in a folded shape from the protruding end of the screw shaft portion, and a locking step portion that locks the periphery of the mounting hole at the tip of each blade portion may be used.

  As described above, in the band clip of the present invention, the main body in which the screw cylinder is provided at one end of the band portion provided with the locking holes at intervals, and the screw shaft portion that is screwed into the screw cylinder are separately provided. The clip is provided, and one of the locking holes of the band portion wound around the wire harness is passed through the screw cylinder, and the screw shaft portion of the clip is screwed into the screw cylinder. Therefore, there is no need to provide a box-shaped main body with an insertion hole for inserting a band, which was required in the past, and the main body is simply a low-profile screw cylinder protruding from the flat plate. The height of the part can be lowered. Therefore, there is an advantage that the wire harness can be routed in a space where the wire harness having the narrow band clip attached thereto cannot be routed.

As shown in FIG. 1, the band clip 10 according to the embodiment includes a main body 2 and a separate clip 3 that is screwed onto the main body 2, and both the main body 2 and the clip 3 are formed of a resin molded product. .

  The main body 2 is attached by winding a band portion 4 around an electric wire group 1 of a wire harness routed to an automobile to bind the electric wire group 1 and screwing a separate clip 3 to the main body 2. As shown in FIG. 3 (B), the band clip 10 inserts and locks the clip 3 into the mounting hole 31 of the vehicle body panel 30 to fix the wire group 1 of the wire harness arranged in the vehicle to the vehicle body. is there.

  As shown in FIG. 2, the main body 2 constituting the band clip 10 is provided with locking holes 4 a at a constant pitch in the band-shaped band portion 4. One end of the band part 4 in the length direction is extended to provide a band locking part / clip attaching part 7. The band locking portion / clip attaching portion 7 is formed in a flat plate shape having the same thickness as the band portion 4 and has a square shape whose width is slightly wider than the width of the band portion 4.

  A clip mounting hole 8 is provided in the center of one surface of the band locking portion and clip mounting portion 7 of the main body 2, and a screw cylinder 9 is projected from the periphery of the clip mounting hole 8. The protruding length of the screw cylinder 9 is 2 mm to 4 mm. On the inner peripheral surfaces of the screw cylinder 9 and the clip mounting hole 8, continuous spiral thread grooves 8a and 9a are provided. As shown in FIG. 4A, a locking projection 8b is provided in the screw groove 8a provided in the clip mounting hole 8 serving as the inner end of these screw grooves. Further, as shown in FIG. 4B, a locking groove portion 11b provided at the tip of a thread 11a of a screw shaft portion 11 to be described later of the clip 3 is abutted to prevent the screw shaft portion 11 from coming off due to inversion. .

  The outer diameter of the screw cylinder 9 is substantially the same as the inner diameter of the locking hole 4 a of the band portion 4. Further, an annular small projection 9b is provided on the outer surface of the protruding end of the screw cylinder 9, and the annular small projection 9b has a V-shaped cross section and a tip surface thereof is a tapered surface 9c.

  As shown in FIGS. 1 and 3, the clip 3 includes a screw shaft portion 11 to be screwed into the screw cylinder 9, an annular plate portion 12 protruding from the outer periphery of the screw shaft portion 11, and a protruding end of the screw shaft portion 11. A pair of blade portions 13 projecting in a more folded shape, and a locking step portion 14 is provided at the protruding end of the pair of blade portions 13. The screw thread 11a is provided on the outer peripheral surface of the screw shaft portion 11 in a spiral manner, and the locking groove portion 11b is provided at the distal end on the insertion side of the screw thread 11a.

Next, the process of attaching the band clip 10 to the wire group 1 of the wire harness will be described.
As shown in FIG. 5 (A), the band portion 4 of the main body 2 is wound around the outer periphery of the electric wire group 1, and the position of the screw tube 9 of the band locking portion / clip attaching portion 7 at one end of the main body 2 in the wound state. The screw cylinder 9 is inserted into one locking hole 4a of the band portion 4 that matches the above. An annular small protrusion 9b is provided at the tip of the screw cylinder 9 at the time of insertion. Since the insertion end face of the annular small protrusion 9b is a tapered surface 9c, the screw cylinder 9 can be pushed into the locking hole 4a without difficulty. . And after pushing in, the band part 4 is prevented from coming off by the annular small protrusion 9, and the main body 2 can be temporarily fixed to the wire group 1.

Next, as shown in FIG. 5B, the screw shaft portion 11 of the clip 3 is screwed into the screw cylinder 9. At the final stage of screwing, the locking groove portion 11b of the screw thread 11a at the insertion end of the screw shaft portion 11 abuts against the locking protrusion 8b at the back end of the screw groove 8a of the clip mounting hole 8 and stops. When the screw shaft portion 11 is screwed in, the state shown in FIG. 5C is obtained, and the band clip 10 is assembled to the wire group 1 of the wire harness.
In this way, the wire harness to which the band clip 10 is attached is routed in the automobile, and the band clip 10 inserts the blade portion 13 of the clip 3 into the attachment hole 31 of the vehicle body panel 30 as shown in FIG. Then, the locking step 14 is locked to the inner periphery of the mounting hole 31 to fix the wire harness to the vehicle body panel 30.

  In the band clip 10 of the present embodiment, since there is no need to provide a relatively high insertion hole or upper wall in which a tongue piece for lock coupling protrudes inside as in the prior art, the height of the main body is reduced. Can be suppressed. Therefore, the wire harness can be routed without difficulty to a portion where the width of the routing space is narrow, and the stability of the wire harness fixed to the vehicle body can be enhanced. Further, since the upper wall and the side wall in the case of a box-shaped main body are not required, it is possible to reduce the weight and reduce the material cost.
