Description

  The present invention relates to a clip, and more particularly, to a clip capable of attaching a member to be attached to a base to an attachment member.

  Conventionally, there are already known clips capable of attaching various attachment members (for example, connectors of wire harnesses) to attachment members (for example, vehicle body panels). Here, in Patent Document 1 below, for example, as shown in FIGS. 8 to 9, a base 310 having a stabilizer 310 a and a pair of locking legs 324 and 324 formed from the base 310 via a support column 322 are provided. There is disclosed a clip 301 that includes an anchor portion 320 that can be attached to a vehicle body panel P with a connector 303 of a wire harness 302 attached to a base portion 310. When the stabilizer 310a is provided in this way, the vehicle body panel P1 having a specified thickness even if a gap is formed in the anchor portion 320 in order to correspond to the vehicle body panel P2 having an unspecified thickness by burr or painting. When assembling, the stabilizer 310a can close the gap. Therefore, any body panel P1, P2 (body panel P1 having a specified thickness, body panel P2 having an unspecified thickness due to burrs or painting) prevents rattling and abnormal noise of the assembled clip 301. it can.

JP 2001-330016 A

  However, in the technique of Patent Document 1 described above, when there is a height restriction or the like at the assembly location of the clip 301 in relation to peripheral parts (for example, when the assembly location of the clip 301 is a small space), FIGS. As shown, the base 310 of the clip 401 could not be provided with the stabilizer 310a. In that case, as shown in the partially enlarged view of FIG. 11, when the clip 401 is assembled to the vehicle body panel P1 having a prescribed thickness, the gap S formed in the anchor portion 320 cannot be closed, so the assembled clip There is a problem that rattling or abnormal noise occurs in 401. In order to solve this problem, as shown in FIG. 12, a clip 501 in which linear ribs 318 and 318 are formed on the inner surface of the base 310 has been considered. However, in this idea, when the clip 501 is assembled to the vehicle body panel P2 having an unspecified thickness due to burrs or painting (see FIGS. 13A and 13B), the ribs 318 and 318 interfere with the vehicle body panel P2. Even so, the base 310 remains bottomed. Therefore, since the ribs 318 and 318 need to be crushed by the vehicle body panel P2 (see FIG. 13C), the insertion load for assembling the clip 501 is large.

  The present invention is intended to solve such a problem. The purpose of the present invention is to assemble not only a specified thickness but also a clip with a mounting space having an unspecified thickness due to burrs or coating, with a small space for mounting. Even if it exists, it is preventing the rattle and noise of the clip assembled | attached to the attachment member, without requiring a big insertion load.

The present invention is for achieving the above object, and is configured as follows.
The invention according to claim 1 includes a base portion to which a member to be attached can be attached and an anchor portion including a locking leg formed from the base portion via a support column, and is formed in a plate-like attachment member. By inserting the locking leg into the mounting hole and engaging the mounting member between the inserted locking leg and the base, it is possible to attach the mounted member attached to the base to the mounting member, On the inner surface side of the base portion, a rib is formed in a linear shape to prevent backlash generated between the engaged mounting members, and the rib extends along the outer edge on the inner surface side of the base portion. It is formed so as to project obliquely outward, and a concave groove is formed on the inner surface side of the base portion so as to follow the inner side of the rib.
According to this configuration, when the clip is assembled to the attachment member having the specified thickness, the rib is not crushed by the attachment member, so that the insertion load for assembling the clip does not increase. In addition, since the ribs fill the gaps formed in the anchor portion, it is possible to prevent the assembled clip from rattling or abnormal noise. On the other hand, when a clip is assembled to an attachment member having an unspecified thickness due to burrs or painting, even if the rib interferes with the attachment member, the base portion is bent so that both sides warp against the attachment member without bottoming. At this time, since the rib is shaped to protrude outward, the rib is pushed down outward by the mounting member. Therefore, both sides of the base and the ribs are not crushed by the mounting member, so that the insertion load for assembling the clip does not increase. In addition, since the gap formed in the anchor portion is packed with both sides of the base portion where the restoring force is applied and the ribs, it is possible to prevent the assembled clip from rattling or abnormal noise.

  Hereinafter, the form for implementing this invention is demonstrated using FIGS. In the following description, an example in which the “attached member” is “the connector 3 of the wire harness 2” and the “attachment member” is “the vehicle body panel P” will be described, as in the related art.

  As shown in FIGS. 1 to 4, the clip 1 mainly includes a base 10 formed in a plate shape so that the connector 3 of the wire harness 2 can be inserted and attached, and a pair of bases 10 formed from the base 10 via a support 22. It is comprised from the anchor part 20 which consists of the locking legs 24 and 24. FIG. The pair of locking legs 24, 24 corresponds to “locking legs” described in the claims. In addition, since the anchor part 20 may be a well-known thing, the detail of the base 10 is demonstrated below.

  Three protrusions 14 (first protrusion 14a, second protrusion 14b, and third protrusion in order from the inside) are formed on the inner surface of the base 10 (the surface of the surface of the base 10 that faces the anchor portion 20). 14c) and 14 (in order from the inside, the first protrusion 14a, the second protrusion 14b, and the third protrusion 14c) are formed at appropriate intervals along the front-rear direction so as to form a pair on the left and right. . A rib 18 is formed on the third protrusion 14c so as to project obliquely outward along the outer edge thereof.

  Thus, since the three protrusions 14 (in order from the inside, the first protrusion 14a, the second protrusion 14b, and the third protrusion 14c) are formed at an appropriate interval, the first protrusion 14a and Between the second protrusion 14b and between the second protrusion 14b and the third protrusion 14c, there are two grooves 16 (first groove 16a and second groove 16b in order from the inside). ) Will be formed. The second concave groove 16b corresponds to a “concave groove” recited in the claims. The base 10 is configured in this way.

  Next, with reference to FIG. 5, the assembly work of the clip 1 with respect to the vehicle body panel P2 will be described. From the state shown in FIG. 5A, the operator performs an operation of assembling (inserting) the pair of locking legs 24, 24 of the clip 1 into the mounting hole 32 of the vehicle body panel P2. Then, the pair of locking legs 24, 24 bends so as to approach each other. Further, when the inserting operation is performed, the engaging protrusions 24a, 24a of the pair of locking legs 24, 24 get over the mounting hole 32 of the vehicle body panel P2, and thus the ribs 18 of the third protrusions 14c, 14c. , 18 interfere with the vehicle body panel P2.

  Then, since the second grooves 16b and 16b are formed on both sides of the base portion 10 (both sides on which the ribs 18 and 18 are formed), both sides of the base portion 10 warp against the vehicle body panel P2 without bottoming. (See FIG. 5B). In the partially enlarged view of FIG. 5B, the base 10 is bent from the state indicated by the imaginary line to the state indicated by the solid line. At this time, since the ribs 18 are outwardly projected, the ribs 18 are pushed outward by the vehicle body panel P2.

  Eventually, the engagement ribs 24b, 24b of the pair of locking legs 24, 24 are caught on the edge of the mounting hole 32 of the vehicle body panel P2. Then, since the operator can obtain a feeling of moderation (feeling of catching) of the catch, it can be determined that the assembly of the clip 1 is completed. Therefore, the operator can finish this assembling work (work for inserting the pair of locking legs 24, 24 into the mounting holes 32 of the vehicle body panel P2).

  When this assembling work is completed, as shown in FIG. 5C, a restoring force is applied to the vehicle body panel P2 so that both sides of the base portion 10 return to the state before being bent. Similarly, the restoring force is applied to the vehicle body panel P2 so that the rib 18 returns to the state before being pushed down. Since the gaps formed in the anchor portion 20 can be closed by both sides of the base portion 10 and the ribs 18 and 18 on which the restoring force is applied, the vehicle body has an unspecified thickness due to burrs or painting, as in the prior art. Even with the panel P2, it is possible to prevent the assembled clip 1 from rattling or abnormal noise.

  Of course, when the clip 1 is assembled to the vehicle body panel P1 having a prescribed thickness instead of assembling the clip 1 to the vehicle body panel P2 having a prescribed thickness by burr or painting, the rib 18 Since 18 is packed, the assembled clip 1 can be prevented from rattling or abnormal noise.

  The clip 1 according to the embodiment of the present invention is configured as described above. According to this configuration, the left and right third protrusions 14c and 14c are respectively formed with ribs 18 projecting obliquely outward along the outer edges thereof. In addition, second concave grooves 16b are formed between the left and right second protrusions 14b and the third protrusions 14c, respectively. Therefore, when the clip 1 is assembled to the vehicle body panel P1 having a prescribed thickness, the ribs 18 and 18 are not crushed by the vehicle body panel P1, so that the insertion load for assembling the clip 1 does not increase. Moreover, since the ribs 18 and 18 close the gap formed in the anchor portion 20, the assembled clip 1 can be prevented from rattling or abnormal noise. On the other hand, when the clip 1 is assembled to the vehicle body panel P2 having an unspecified thickness due to burrs or painting, the base 10 is bottomed even if the ribs 18 and 18 of the third protrusions 14c and 14c interfere with the vehicle body panel P2. However, both sides are bent so as to warp against the vehicle body panel P2 (see FIG. 5B). At this time, since the ribs 18 are outwardly projected, the ribs 18 are pushed outward by the vehicle body panel P2. Therefore, both sides of the base 10 and the ribs 18 and 18 are not crushed by the vehicle body panel P2, so that the insertion load for assembling the clip 1 does not increase. Further, since the gap formed in the anchor portion 20 is filled with both sides of the base portion 10 where the restoring force is applied and the ribs 18 and 18, rattling and abnormal noise of the assembled clip 1 can be prevented.

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 the embodiment, three protrusions 14 (a first protrusion 14 a, a second protrusion 14 b, and a third protrusion 14 c) are formed on the inner surface of the base portion 10, and the second protrusion among the three protrusions 14 is formed. The form in which the second concave groove 16b is formed by the 14b and the third protrusion 14c has been described. However, the present invention is not limited to this, and the second concave groove 16b may be formed on the inner surface of the base portion 10 itself. In that case, the three protrusions 14 are unnecessary.

  In the embodiment, the “attached member” is the “connector 3 of the wire harness 2” and the “attachment member” is the “body panel P”. However, the present invention is not limited to this, and various forms are conceivable.

  Further, in the embodiment, the description has been given of the form in which the “locking legs” are “one pair”. However, the present invention is not limited to this and may be “one”. In that case, it may be simply “one locking leg” or “the locking leg is umbrella-shaped at the tip of the column 22”.

  Moreover, in the Example, the 2nd ditch | groove 16b demonstrated the form formed in the inner surface of the base 10. FIG. However, it is not limited to this, The 2nd ditch | groove 16b may be formed in the outer surface of the base 10 (refer modification 1 and FIG. 6). At this time, the third protrusion 14c may be eliminated (see Modification 2 and FIG. 7).
