Description

  The present invention relates to a holder and an attachment structure for attaching the holder to an attachment target member.

Conventionally, in a vehicle, an electrical component such as a wire harness is attached to a vehicle body via a holder (see, for example, Patent Document 1).
An example of such a holder is a protector described in Patent Document 1. This protector has a main body that accommodates and holds the wire harness, and a fixing portion that protrudes from the side wall of the main body and is fixed to the vehicle body panel via a bolt or the like. Further, an elastic piece formed of an elastic material is attached to the main body of the protector. According to such a protector, the elastic piece is elastically deformed and pressed against the vehicle body panel in a state where the protector is fixed to the vehicle body panel, thereby suppressing the play of the protector against the vehicle body panel.

JP 2013-169803 A

  By the way, the inventor of the present application has developed a holder made of a hard resin material in which a portion (hereinafter referred to as a support portion) corresponding to the elastic piece is integrally formed with a protector main body (hereinafter referred to as a holder main body). In this case, for example, when a holder is attached to an attachment target member such as a vehicle body panel, if a foreign object is interposed between the attachment target member and the support portion, the support portion is more than expected due to the attachment of the holder. There is a risk of deformation and breakage. Further, during the attaching operation of the holder, the holder may be pulled to check whether or not the holder is securely attached to the attachment target member. At this time, the support part may be deformed more than expected and break. As a result, the play of the holder cannot be appropriately suppressed.

  Such a problem may occur in the same manner in a holder formed of a material other than a hard resin material such as a metal material. Further, the same may occur in a holder in which the support portion is separated from the holder main body.

  An object of the present invention is to provide a holder and a mounting structure for the holder that can appropriately suppress rattling.

  A holder for achieving the above object is a holder provided with a holder main body and a mounting portion provided on the holder main body and attachable to the mounting target member, and provided so as to support the mounting target member. And a support part that elastically deforms and suppresses the relative displacement when an external force that relatively displaces the holder main body acts on the attachment target member, and the attachment target in the middle of the elastic deformation of the support part And a restricting portion that restricts further elastic deformation of the support portion by contacting the member.

  According to this configuration, in a state where the attachment portion of the holder is attached to the attachment target member, the support portion supports the attachment target member. When an external force that relatively displaces the holder body acts on the attachment target member and the support portion and the attachment target member are about to approach, the support portion is elastically deformed to suppress the relative displacement, so-called rattling. The

  Moreover, according to the said structure, the further elastic deformation of the support part is controlled because a control part contact | abuts the attachment object member in the middle of the said elastic deformation of a support part. For this reason, breakage of the support portion can be suppressed.

  According to the present invention, rattling can be appropriately suppressed.

Sectional drawing along line 5-5 in FIG. The perspective view which shows the state in which the holder in the embodiment was mounted in the vehicle.

Hereinafter, an embodiment will be described with reference to FIGS.
As shown in FIG.1 and FIG.2, the holder 10 is attached to the surrounding wall 91 of the reinforcement 90 of a vehicle, and hold | maintains a wire harness (not shown). The reinforcement 90 has a cylindrical shape and extends along the vehicle width direction W. The reinforcement 90 is a reinforcing member for the vehicle body, and is positioned between a dash panel separating the engine room and the vehicle compartment provided in the front part of the vehicle and an instrument panel positioned in front of the front seat. ing.

The holder 10 includes a holder body 11 that extends along the front-rear direction of the vehicle (hereinafter, the front-rear direction L).
As shown in FIG. 2, an opposing portion 12 that faces the upper outer peripheral surface of the peripheral wall 91 of the reinforcement 90 is formed on the lower surface of the rear portion of the holder main body 11. The facing portion 12 has a circular arc shape along the upper outer peripheral surface of the peripheral wall 91.

  As shown in FIGS. 2, 4, and 5, two clip portions 20 are provided on the facing portion 12 so as to protrude from each other in the vehicle width direction W. The clip portion 20 includes a base portion 21 and an engaging portion 22 that extends from the lower end of the base portion 21. The outer diameter of the engaging portion 22 is larger than that of the base portion 21 at the upper end, and is gradually reduced downward.

  The engagement portions 22 of the two clip portions 20 are respectively inserted into two attachment holes 92 formed in the upper part of the peripheral wall 91 of the reinforcement 90 and engaged with the peripheral edge of the attachment hole 92, whereby the reinforcement 90. Is attached to the holder 10.

  As shown in FIGS. 1 and 2, a plurality of insertion holes 13 </ b> A to 13 </ b> D for inserting and fixing the connector of the wire harness are formed on the upper surface, the lower surface, and the front side surface of the front portion of the holder body 11. Yes.

A protrusion 14 is formed on the front side surface of the holder body 11, and an attachment hole 15 is formed in the protrusion 14.
As shown in FIGS. 1, 3, and 4, the lower end portion of the rear end surface of the holder main body 11 is formed with a plate-like first support portion 30 that extends obliquely downward and bends to extend downward. . In a state where the holder 10 is attached to the reinforcement 90, the distal end portion of the first support portion 30 is pressed against the outer peripheral surface of the peripheral wall 91 of the reinforcement 90. Thus, the 1st support part 30 differs from the position (position at 12:00 in FIG. 2) in the circumferential direction different from the position (position at 12:00 in FIG. 2) where the clip section 20 is attached on the outer peripheral surface of the peripheral wall 91. Position). And when the external force which carries out relative displacement of the holder main body 11 with respect to the reinforcement 90 acts, the said 1st support part 30 elastically deforms, and the said relative displacement is suppressed.

  As shown in FIGS. 1 to 4, a pair of opposed wall portions that protrude rearward on the rear end surface of the holder main body 11 and face each other with the first support portion 30 sandwiched from both sides in the vehicle width direction W. 33 is formed. A connecting portion 34 that connects the tip portions is formed between the tip portions of the pair of opposing wall portions 33. Therefore, the first support portion 30 is surrounded from three sides by the pair of opposing wall portions 33 and the connecting portion 34. Further, as shown in FIG. 4, the lower surfaces of the pair of opposing wall portions 33 and the connecting portion 34 are separated from the outer peripheral surface of the peripheral wall 91 of the reinforcement 90 rather than the distal end portion of the first support portion 30. Therefore, in the middle of the elastic deformation of the first support part 30, the lower surface of the pair of opposing wall parts 33 and the coupling part 34 abuts on the outer peripheral surface of the peripheral wall 91, thereby restricting further elastic deformation of the first support part 30. It has come to be. In the present embodiment, the first restricting portion 32 is configured by the pair of opposing wall portions 33 and the connecting portion 34.

  As shown in FIGS. 1, 2, 4, and 5, a pair of plate-like second support portions 40 that extend obliquely downward and bend and extend downward are formed on both side surfaces of the holder body 11, respectively. Has been. In a state where the holder 10 is attached to the reinforcement 90, the tip portions of the pair of second support portions 40 are pressed against the outer peripheral surface of the peripheral wall 91 of the reinforcement 90. In this way, the pair of second support portions 40 respectively support different positions in the axial direction (vehicle width direction W) of the reinforcement 90 from the position where the clip portion 20 is attached on the outer peripheral surface of the peripheral wall 91. And when the external force which carries out relative displacement of the holder main body 11 with respect to the reinforcement 90 acts, the said 2nd support part 40 elastically deforms, and the said relative displacement is suppressed.

  A pair of opposing wall portions 43 are formed on both side surfaces of the holder main body 11 so as to protrude outward in the vehicle width direction W and to face each other with the second support portion 40 sandwiched from the front and rear. A connecting portion 44 that connects the tip portions is formed between the tip portions of the pair of opposing wall portions 43. Therefore, the second support portion 40 is surrounded from three sides by the pair of opposing wall portions 43 and the connecting portion 44. Further, as shown in FIG. 5, the lower surfaces of the pair of opposing wall portions 43 and the connecting portion 44 are separated from the outer peripheral surface of the peripheral wall 91 of the reinforcement 90 rather than the distal end portion of the second support portion 40. Therefore, in the course of the elastic deformation of the second support portion 40, the lower surfaces of the pair of opposing wall portions 43 and the connecting portion 44 abut against the outer peripheral surface of the peripheral wall 91, thereby restricting further elastic deformation of the second support portion 40. It has come to be. In the present embodiment, the second restricting portion 42 is configured by the pair of opposing wall portions 43 and the connecting portion 44.

The holder main body 11, the projecting portion 14, the clip portion 20, the support portions 30 and 40, and the restricting portions 32 and 42 constituting the holder 10 of the present embodiment are integrally formed of a hard resin material.
FIG. 6 shows an example of a state in which the holder 10 of this embodiment is mounted on a vehicle.

  As described above, the holder 10 is attached to the reinforcement 90 as shown in FIG. 6 by inserting the clip portion 20 (see FIG. 2) into the attachment hole 92. Connectors 93A and 93B of a wire harness 93 extending from the engine (not shown) are inserted and fixed in the insertion holes 13A and 13B of the holder 10, respectively. Further, a clip 95 for holding the wire harness 94 is fitted into the mounting hole 15 (see FIG. 1) of the protruding portion 14.

Next, the operation of this embodiment will be described.
In a state in which the clip portion 20 of the holder 10 is attached to the outer peripheral surface of the peripheral wall 91 of the reinforcement 90, the position where the first support portion 30 is attached to the clip portion 20 on the outer peripheral surface of the peripheral wall 91 is the circumferential direction. It will support different positions. Moreover, the 2nd support part 40 will support the position where an axial direction differs from the position where the clip part 20 is attached in the outer peripheral surface of the surrounding wall 91 at this time.

  When the external force that relatively displaces the holder main body 11 with the clip portion 20 as a fulcrum acts on the peripheral wall 91 and the first support portion 30 and the outer peripheral surface of the peripheral wall 91 try to approach each other, the first support portion 30 The relative displacement is suppressed by elastic deformation.

  Further, when an external force that relatively displaces the holder body 11 acts on the peripheral wall 91 with the clip portion 20 as a fulcrum, when one of the two second support portions 40 and the outer peripheral surface of the peripheral wall 91 try to approach each other, The relative displacement is suppressed by elastically deforming the second support portion 40.

  Further, for example, when the operator confirms the insertion and removal of the connectors 93A and 93B of the wire harness 93 and an external force is applied to the holder 10 in the direction indicated by the arrow B in FIG. It will be deformed. However, at this time, further elastic deformation of the first support part 30 is restricted by the first restriction part 32 coming into contact with the reinforcement 90 during the elastic deformation of the first support part 30. For this reason, breakage of the first support portion 30 is suppressed.

  Similarly, when an external force is applied to the holder 10 in the direction indicated by the arrow C or D in FIG. 5, the second support portion 40 is elastically deformed. However, at this time, further elastic deformation of the second support part 40 is restricted by the second restriction part 42 coming into contact with the reinforcement 90 during the elastic deformation of the second support part 40. For this reason, breakage of the second support portion 40 is suppressed.

According to the holder and the holder mounting structure according to the present embodiment described above, the following effects can be obtained.
(1) The holder 10 is provided so as to be able to support the outer peripheral surface of the peripheral wall 91 of the reinforcement 90, and is elastically deformed when an external force that relatively displaces the holder main body 11 is applied to the reinforcement 90. The 1st support part 30 to suppress is provided. Further, the holder 10 includes a first restricting portion 32 that restricts further elastic deformation of the first support portion 30 by contacting the reinforcement 90 during the elastic deformation of the first support portion 30.

According to such a configuration, by exerting the above-described operation, breakage of the first support portion 30 can be suppressed, and rattling of the holder 10 can be appropriately suppressed.
In addition, since the rattling of the holder 10 can be appropriately suppressed, the resonance between the reinforcement 90 and the holder 10 can be suppressed, and the generation of abnormal noise due to the resonance can be suppressed.

  (2) The holder main body 11, the clip part 20, the first support part 30, and the first restriction part 32 are integrally formed of a resin material. For this reason, the number of parts of the holder 10 can be reduced by integrally forming the holder 10.

(3) The first restricting portion 32 has a pair of opposing wall portions 33 that face each other with the first support portion 30 interposed therebetween.
According to such a configuration, the first support portion 30 is sandwiched between the pair of opposing wall portions 33 constituting the first restricting portion 32. For this reason, when attaching the holder 10 with respect to the reinforcement 90, it can suppress that foreign materials, such as a ground terminal, enter between the reinforcement 90 and the 1st support part 30 on both sides of the 1st support part 30. it can. Therefore, breakage of the first support portion 30 due to the entry of foreign matter can be suppressed.

(4) The first restricting portion 32 has a connecting portion 34 that connects the pair of opposing wall portions 33, and the first support portion 30 is surrounded by the pair of opposing wall portions 33 and the connecting portion 34. ing.
According to such a configuration, the pair of opposing wall portions 33 constituting the first restricting portion 32 are connected to each other by the connecting portion 34, so that the rigidity of the first restricting portion 32 is increased. Moreover, since the 1st support part 30 is surrounded by a pair of opposing wall part 33 and the connection part 34, when attaching the holder 10 with respect to the reinforcement 90, between the reinforcement 90 and the 1st support part 30 It is possible to suppress the entry of foreign matter into the three sides surrounding the first support portion 30. Therefore, breakage of the first support portion 30 due to the entry of foreign matter can be effectively suppressed.

  (5) The holder 10 is provided so as to be able to support a position in the axial direction (vehicle width direction W) different from the position where the clip portion 20 is attached on the outer peripheral surface of the peripheral wall 91 of the reinforcement 90. On the other hand, a second support portion 40 that elastically deforms and suppresses the relative displacement when an external force that relatively displaces the holder main body 11 is applied is provided. Further, the holder 10 includes a second restricting portion 42 that restricts further elastic deformation of the second support portion 40 by abutting against the reinforcement 90 during the elastic deformation of the second support portion 40.

  According to such a configuration, even when the holder main body 11 is relatively displaced with respect to the peripheral wall 91 so that the portion where the first support portion 30 is provided and the outer peripheral surface of the peripheral wall 91 are close to each other, the second support portion 40 is Even when the holder main body 11 is relatively displaced with respect to the peripheral wall 91 so that the provided portion and the outer peripheral surface of the peripheral wall 91 are close to each other, the relative displacement can be suppressed. Therefore, the occurrence of rattling can be effectively suppressed.

  (6) A pair of second support portions 40 are provided with the holder main body 11 interposed therebetween. For this reason, even when the holder main body 11 is relatively displaced with respect to the peripheral wall 91 so that one of the pair of second support portions 40 and the outer peripheral surface of the peripheral wall 91 of the reinforcement 90 are close to each other, Even when the holder main body 11 is relatively displaced with respect to the peripheral wall 91 so that the other and the outer peripheral surface of the peripheral wall 91 are close to each other, the relative displacement can be suppressed. Therefore, the occurrence of rattling can be effectively suppressed.

  (7) The attachment structure of the holder 10 includes the holder 10 and a reinforcement 90 to which the clip portion 20 of the holder 10 is attached. The reinforcement 90 is supported by the first support part 30 of the holder 10, and the first support part 30 comes into contact with the reinforcement 90 during the elastic deformation of the first support part 30, thereby supporting the first support. It is comprised so that the further deformation | transformation of the part 30 may be controlled.

According to such a structure, the effect according to the said effect (1) can be show | played.
<Modification>
In addition, the said embodiment can also be changed as follows, for example.

  -Either one of a pair of 2nd support parts 40 can also be abbreviate | omitted. Moreover, the 2nd support part 40 itself can also be abbreviate | omitted. Even in this case, when the external force that relatively displaces the holder main body 11 acts on the peripheral wall 91 and the first support portion 30 and the outer peripheral surface of the peripheral wall 91 try to approach each other, the first support portion 30 The relative displacement is suppressed by elastic deformation.

  The attachment target member is not limited to the reinforcement 90, and another member having a cylindrical shape or a columnar shape may be used as the attachment target member. In addition, the attachment target member is not limited to a cylindrical or columnar shape, and may have an attachment surface having another curved surface shape or an attachment surface having a planar shape. In this case, what is necessary is just to change shapes, such as the opposing part 12 of the holder main body 11, the 1st support part 30, the 2nd support part 40, so that it may correspond to the shape of the attachment surface of an attachment object member.

  -The connection part 34 of the 1st control part 32 is also omissible. Even in this case, since the first support portion 30 is sandwiched between the pair of opposing wall portions 33 constituting the first restricting portion 32, the first reinforcement 90 and the first reinforcement 90 are attached to the reinforcement 90 when the holder 10 is attached. It is possible to prevent foreign matter from entering between the support portions 30 on both sides of the first support portion 30. Further, one of the pair of opposing wall portions 33 can be omitted. Further, the same change as described above can be made to the connecting portion 44 and the opposing wall portion 43 of the second restricting portion 42.

-The shape of the 1st support part 30 or the 2nd support part 40 can be changed suitably. For example, the 1st support part 30 and the 2nd support part 40 can also make a curved-plate shape as a whole.
For example, the clip part 20 may be formed separately from the holder body 11 and the clip part may be joined to the holder body. Moreover, the 1st support part 30 and the 1st control part 32 may be formed separately from the holder main body 11, and you may make it join a 1st support part and a 1st control part with respect to a holder main body. In this case, the holder body 11 and the first support part 30 and the first restricting part 32 can be formed of different materials. Further, the second support portion 40 and the second restricting portion 42 may be modified in the same manner as described above.
