Description

  The present invention relates to a belt clamp, and more particularly to a belt clamp capable of binding an object to be bound to an anchor.

  Conventionally, as shown in, for example, a belt clamp is already known as a fastener for fastening a wire harness (bound object) wired inside an automobile or the like to a vehicle body panel (attached member) (Patent Document 1). reference). As shown in FIGS. 23 to 25, the belt clamp 101 mainly includes a belt 120 around which the outer peripheral surface of the wire harness 170 can be wound, a buckle b to which the base end 122 side of the belt 120 is coupled, and a buckle b. The anchor 130 is integrally formed and can be attached to the attachment hole 152 of the vehicle body panel 150. And this belt clamp 101 inserts the front-end | tip 124 side of the belt 120 around which the wire harness 170 is wound into the belt insertion path 138 formed in the buckle b, and tightens the belt 120 and the buckle b in this tightened state. Is locked, and after this lock, the excess portion of the belt 120 drawn out from the outlet of the belt insertion path 138 can be cut to bind the wire harness 170 to the buckle b. Thereby, since the wire harness 170 can be bundled with the buckle b, when the anchor 130 with the wire harness 170 tied to the buckle b is attached to the attachment hole 152 of the vehicle body panel 150, the wire harness 170 may be fastened to the vehicle body panel 150. (See FIGS. 25-26).

Utility Model Registration No. 3176869

  However, the belt clamp 101 of Patent Document 1 described above has a structure in which the belt 120 around which the outer peripheral surface of the wire harness 170 is wound and the buckle b are locked, as is apparent from FIGS. In such a structure, in the height direction of the belt clamp 101, a bulk corresponding to the height of the buckle b may occur. Therefore, this wire harness 170 may interfere with the peripheral object 160 of the vehicle body panel 150. Moreover, in the belt clamp 101 of patent document 1 mentioned above, it has the structure which binds the wire harness 170 to the buckle b. In such a structure, since the width L2 of the buckle b is short, the path regulation of the bundled wire harness 170 may be insufficient. Therefore, when an external force (an arrow in FIG. 27) acts on the bundled wire harness 170, the outer peripheral surface of the wire harness 170 may interfere with the edge e of the vehicle body panel 150 (see FIG. 27). Therefore, the outer peripheral surface of the wire harness 170 may be damaged.

  An object of the present invention is to provide a belt clamp capable of protecting a bound object from an edge of a member to be attached while suppressing bulkiness in a height direction. .

The present invention is for achieving the above object, and is configured as follows.
The invention according to claim 1 includes a belt and an anchor to which the base end side of the belt is coupled, and the front end side of the belt around which the object to be bound is wound is inserted into a belt insertion path formed on the anchor. By tightening, the belt and the anchor are locked in this tightened state, and the object to be bound can be bound to the anchor. The belt insertion path is formed inside along the axial direction of the anchor. The anchor is formed with a receiving member capable of receiving the object to be bound around which the belt is wound along the axial direction thereof.

  According to the first aspect of the present invention, as described in the prior art, no bulkiness corresponding to the height of the buckle occurs in the height direction of the belt clamp. Therefore, the object to be bound does not interfere with the member 60 (for example, the vehicle body panel) to which the belt clamp is attached. According to the first aspect of the present invention, the receiving length for receiving the object to be bound in the receiving member is set sufficiently longer than the width of the buckle of the prior art. Will not be insufficient. Therefore, even if an external force (for example, an arrow in FIG. 6) acts on the bound object to be bound, the outer peripheral surface of the bound object does not interfere with the edge of the attached member. Therefore, the outer peripheral surface of the object to be bound is not damaged.

  Moreover, invention of Claim 2 is a belt clamp of Claim 1, Comprising: The receiving member is formed in the curved shape along the outer peripheral surface of a to-be-bound object.

  According to invention of Claim 2, a receiving member can receive a to-be-bound thing firmly. For this reason, it is possible to more sufficiently implement the path regulation of the bundled objects to be bound.

  The invention described in claim 3 is the belt clamp according to any one of claims 1 and 2, wherein the receiving member is formed with a pair of ribs capable of holding the object to be bound.

  According to the invention described in claim 3, it is possible to sufficiently carry out the path regulation of the bundled objects to be bound.

  According to a fourth aspect of the present invention, in the belt clamp according to the third aspect, the pair of ribs are formed with a restraining portion for preventing the clamped object from falling off.

  According to invention of Claim 4, path | route control of the to-be-bundled thing to be bound can be implemented more fully.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
Example 1
First, Embodiment 1 of the present invention will be described with reference to FIGS. In the following description, an example in which the “bound member” is the “wire harness 70” will be described.

  As shown in FIG. 1, the belt clamp 1 is an integrally molded product made of a synthetic resin material having rigidity such as PP, and its configuration is mainly composed of a belt 20, an anchor 30, and a pair of receiving members 40. It is divided roughly. Below, these belt 20, the anchor 30, and the receiving member 40 are demonstrated separately.

  First, the belt 20 will be described (see FIG. 2). The belt 20 has a belt-like shape extending straight with a constant width. The base end 22 side of the belt 20 is coupled so as to be integrated with an anchor 30 described later. On the other hand, the front end 24 side of the belt 20 is a free end that is tapered. Rack teeth 26 are formed on the inner surface of the belt 20 at a constant pitch along the longitudinal direction of the belt 20. The belt 20 is configured in this way.

  Next, the anchor 30 will be described. The anchor 30 includes an elastic dish-shaped stabilizer 32, a support column 34 protruding from the center of the stabilizer 32, and a pair of elastic claws 36 projecting from the distal end side to the proximal end side of the support column 34. ing. The anchor 30 can be attached by being inserted into an attachment hole 52 formed in advance in the wiring route of the vehicle body panel 50.

  A belt insertion path 38 having an inlet 38a and an outlet 38b into which the belt 20 can be inserted and pulled out along the axial direction is formed inside the anchor 30 (see FIG. 3). An engagement piece 38c is formed on the inner surface of the belt insertion path 38. The engagement piece 38c can be bent inward and outward of the column 34 by the elasticity of the synthetic resin material. An engaging claw 38d that can engage with the rack teeth 26 of the belt 20 is formed on the distal end side of the engaging piece 38c. The anchor 30 is configured in this way.

  Finally, the receiving member 40 will be described (see FIG. 2). The receiving member 40 is configured to form a pair, and is configured of a plate-like member that can receive the wire harness 70 around which the belt 20 is wound along the axial direction thereof. Therefore, as is apparent from FIG. 2, the receiving length L1 for receiving the wire harness 70 in both receiving members 40 is set sufficiently longer than the width L2 of the buckle b of the prior art.

  A pair of ribs 42 that can sandwich the outer peripheral surface of the wire harness 70 are formed at the tip of the receiving member 40. The receiving member 40 is formed so as to be integrated with the outside of the stabilizer 32 of the anchor 30 so as to be away from each other. Thereby, this receiving member 40 will be formed so that the wire harness 70 around which the belt 20 is wound can be received along its axial direction. The receiving member 40 is configured in this way. The belt clamp 1 is composed of the belt 20, the anchor 30, and the receiving member 40.

  Then, the fastening operation | work which fastens the wire harness 70 to the vehicle body panel 50 is demonstrated. First, an operation of winding the belt 20 of the belt clamp 1 around the outer peripheral surface of the wire harness 70 is performed. Next, the tip 24 of the belt 20 around which the wire harness 70 is wound is inserted into the inlet 38 a of the belt insertion path 38 of the anchor 30 and pulled out from the outlet 38 b and temporarily tightened. As a result, the rack teeth 26 of the belt 20 and the engaging claws 38d of the engaging pieces 38c of the anchor 30 slide in accordance with the temporary fastening operation, and the mutual 26 and 38d are temporarily engaged in a predetermined temporary fastening state. Then, the belt 20 and the anchor 30 are temporarily locked.

  At this time, both receiving members 40 are in a state of receiving (supporting) the wire harness 70 along the axial direction. In this receiving state, the pair of ribs 42 are in a state of sandwiching the outer peripheral surface of the wire harness 70. Next, an operation for operating the dedicated tool is performed in a state where an insertion port (none of which is shown) of the dedicated tool is inserted into the tip of the anchor 30 of the belt clamp 1. Then, the belt 20 around which the wire harness 70 is wound is tightened until the belt 20 reaches a predetermined tightening state, whereby the rack teeth 26 of the belt 20 and the engagement claws 38d of the engagement pieces 38c of the anchor 30 are engaged. And the anchor 30 are locked.

  After this lock, the excess portion of the belt 20 drawn out from the outlet 38b of the belt insertion path 38 of the anchor 30 is cut by a dedicated tool. Thereby, the wire harness 70 can be bound to the receiving member 40 of the anchor 30 of the belt clamp 1. Thus, the wire harness 70 can be fastened to the vehicle body panel 50 by attaching the anchor 30 of the belt clamp 1 to which the wire harness 70 is bound to the attachment hole 52 of the vehicle body panel 50 (see FIGS. 4 to 5). The belt clamp 1 is configured in this way.

  The belt clamp 1 according to the first embodiment of the present invention is configured as described above. According to this configuration, a belt insertion path 38 having an inlet 38 a and an outlet 38 b into which the belt 20 can be inserted and pulled out along the axial direction is formed inside the anchor 30. Thus, the belt insertion path 38 is formed not in the buckle b but in the anchor 30 as described in the prior art. Therefore, as described in the related art, the bulk corresponding to the height of the buckle b does not occur in the height direction of the belt clamp 1. Therefore, the wire harness 70 does not interfere with the peripheral object 60 of the vehicle body panel 50. Further, according to this configuration, the wire harness 70 is bound to the both receiving members 40 of the anchor 30. In such a structure, the receiving length L1 for receiving the wire harness 70 in the both receiving members 40 is set sufficiently longer than the width L2 of the buckle b of the prior art, so the path of the bundled wire harness 70 Regulations will not be insufficient. Therefore, even if an external force (an arrow in FIG. 6) acts on the bundled wire harness 70, the outer peripheral surface of the wire harness 70 does not interfere with the edge E of the vehicle body panel 50 (see FIG. 6). . Therefore, the outer peripheral surface of the wire harness 70 is not damaged.

  Further, according to this configuration, the pair of ribs 42 that can hold the outer peripheral surface of the wire harness 70 are formed at the tip of the receiving member 40. For this reason, it is possible to sufficiently restrict the route of the bundled wire harness 70.

(Example 2)
Next, Embodiment 2 of the present invention will be described with reference to FIG. The second embodiment is a mode in which the path regulation of the bundled wire harness 70 can be more sufficiently performed as compared with the first embodiment already described. In the following description, members having the same or equivalent configuration as in the first embodiment are denoted by the same reference numerals in the drawings, and redundant description will be omitted. This also applies to all the embodiments and modifications described later.

  As shown in FIG. 7, both receiving members 40 of the belt clamp 2 of the second embodiment are formed in a curved shape along the curved outer peripheral surface of the receiving wire harness 70. Therefore, both the receiving members 40 can receive the wire harness 70 firmly. Therefore, the belt clamp 2 according to the second embodiment has the operational effects of the belt clamp 1 according to the first embodiment, and further has the operational effects that the path regulation of the bundled wire harness 70 can be more sufficiently performed.

(Example 3)
Next, Embodiment 3 of the present invention will be described with reference to FIG. The third embodiment is a mode in which the path regulation of the bundled wire harness 70 can be more sufficiently performed as compared with the first embodiment already described.

  As shown in FIG. 8, the pair of ribs 42 of the receiving member 40 of the belt clamp 3 of the third embodiment are formed with holding portions 44 that prevent the pinched wire harness 70 from falling off. Therefore, both the receiving members 40 can receive the wire harness 70 firmly. Therefore, the belt clamp 3 according to the third embodiment has the operation and effect of the belt clamp 1 of the first embodiment, and further has the operation and effect that the path regulation of the bundled wire harness 70 can be more sufficiently performed.

Example 4
Next, Embodiment 4 of the present invention will be described with reference to FIG. The fourth embodiment is a mode in which the path regulation of the bundled wire harness 70 can be more firmly performed as compared with the second embodiment already described.

  As shown in FIG. 9, the pair of ribs 42 of the receiving member 40 of the belt clamp 4 of the fourth embodiment are formed with holding portions 44 that prevent the pinched wire harness 70 from falling off. Therefore, both the receiving members 40 can receive the wire harness 70 firmly. Therefore, the belt clamp 4 of the fourth embodiment has the operational effects of the belt clamp 2 of the second embodiment, and further has the operational effect that the path regulation of the bundled wire harness 70 can be more firmly performed.

  The contents described above are only related to one embodiment of the present invention, and do not mean that the present invention is limited to the above contents.

  In each of the embodiments, the example in which the “bound member” is the “wire harness” has been described. However, the present invention is not limited to this, and any member may be used as long as the “bound member” is a “cable member”.

  Moreover, in each Example, the pair of rib 42 demonstrated the form currently formed in the front-end | tip of the receiving member 40. FIG. However, the present invention is not limited to this, and the pair of ribs 42 may be formed at the base end of the receiving member 40, the center between the front end and the base end, or the entire end from the front end to the base end.

  Moreover, in the belt clamp 1 of Example 1, as shown in FIG. 10, you may comprise only one side, without receiving member 40 making a pair (modification 1). In this case, as is apparent from FIG. 10, the receiving length 1/2 × L1 for receiving the wire harness 70 in the receiving member 40 is set sufficiently longer than the width L2 of the buckle b of the prior art. Also with the belt clamp 5 of the first modification, the same effects as the belt clamp 1 of the first embodiment can be obtained.

  The same applies to the belt clamps 2 to 4 of Examples 2 to 4. That is, as shown in FIGS. 11 to 14, the belt clamps 6 to 8 of the modified examples 2 to 4 with respect to the belt clamps 2 to 4 of the embodiments 2 to 4 are established. In the belt clamps 6 to 8 of the modified examples 2 to 4, the same effects as the belt clamps 2 to 4 of the embodiments 2 to 4 can be obtained.

  Moreover, in the belt clamp 1 of Example 1, as shown in FIG. 14, you may be comprised so that both the receiving members 40 may comprise a substantially L shape (modification 5). Even with the belt clamp 9 of the fifth modification, the same effects as the belt clamp 1 of the first embodiment can be obtained.

  The same applies to the belt clamps 2 to 4 of Examples 2 to 4. That is, as shown in FIGS. 15 to 17, the belt clamps 10 to 12 of the modified examples 6 to 8 with respect to the belt clamps 2 to 4 of the examples 2 to 4 are established. In the belt clamps 10 to 12 of the modified examples 6 to 8, the same effects as the belt clamps 2 to 4 of the examples 2 to 4 can be obtained.

  Moreover, in the belt clamp 9 of the modification 5, as shown in FIG. 18, you may comprise only the substantially L-shaped side, without the receiving member 40 forming a pair (modification 9). In this case, as is apparent from FIG. 18, the receiving length 1/2 × L1 for receiving the wire harness 70 in the receiving member 40 is set sufficiently longer than the width L2 of the buckle b of the prior art. Also with the belt clamp 13 of this modification 9, the same effect as the belt clamp 9 of the modification 5 can be obtained.

  The same applies to the belt clamps 10 to 12 of the modified examples 6 to 8. That is, as shown in FIGS. 19-21, the belt clamps 14-16 of the modification 10-12 with respect to the belt clamps 10-12 of this modification 6-8 are materialized. In the belt clamps 14 to 16 of the modified examples 10 to 12, the same effects as the belt clamps 10 to 12 of the modified examples 6 to 8 can be obtained.

  Moreover, in the belt clamp 3 of Example 3, as shown in FIG. 22, the holding | suppressing part 44 may be a non-return shape (modification 13). When the anti-return shape is thus formed, the wire harness 70 can be clamped more firmly by the holding portion 44 in the belt clamp 17 of the modified example 13.
