  Embodiments of the best mode for carrying out the present invention will be described below with reference to the drawings.

First, the mounting structure of the cushion clip 10 according to the first embodiment of the present invention will be described with reference to FIGS. 1 is a perspective view showing an external appearance of a mounting structure of the cushion clip 10, FIG. 2 is a sectional view taken along the line AA of FIG. 1 showing a mounting state of the cushion clip 10, and FIG. It is a BB sectional view taken on the line.
The cushion clip 10 of this embodiment is inserted into a mounting hole 51 formed in a vehicle body side panel 50 (corresponding to a mounted member of the present invention) made of a conductive steel plate, as well shown in FIG. It is comprised by the insertion site | part 20 fitted and the cushion site | part 30 with which this insertion site | part 20 is mounted | worn in the twisted state, and is made integral. The former insertion portion 20 is inserted and fitted into the attachment hole 51 of the vehicle body side panel 50, thereby holding the cushion clip 10 in a state of being attached to the vehicle body side panel 50. 2 and 3, the latter cushion part 30 is an engine hood 40 made of the same conductive steel plate that can be opened and closed with respect to the vehicle body side panel 50 (on the opening / closing lid of the present invention). When the engine hood 40 is closed, the engine hood 40 is elastically supported on the vehicle body side panel 50 by contacting the engine hood 40 (receiving the operation of closing the engine hood 40).

Specifically, the insertion portion 20 is formed by integrally molding a synthetic resin such as polyacetal resin (POM), and the cushion portion 30 is formed of rubber. The synthetic resin insertion part 20 and the rubber cushion part 30 are both formed by dispersing carbon-based materials (conductive substances) such as carbon black particles and carbon fibers. Thereby, the whole cushion clip 10 is made conductive.
By the way, in general, in a vehicle such as an automobile, electromagnetic waves may be generated from a portion where current or voltage changes suddenly, such as a spark plug in an engine. This electromagnetic wave is accumulated in a portion such as the engine hood 40 and then released indefinitely, and may have various adverse effects on each precision electronic device.
Therefore, by providing conductivity to the cushion clip 10 as described above, the conductive engine hood 40 is brought into contact with the conductive vehicle body side panel 50 via the conductive cushion clip 10. Thereby, emission of electromagnetic waves from the engine hood 40 is prevented.
Hereinafter, the configuration of each unit will be described in detail.

First, as shown in FIG. 1, an attachment hole 51 for attaching the cushion clip 10 is formed in the conductive vehicle body side panel 50. Specifically, the mounting holes 51 are formed at a plurality of positions such as both corners and the central part of the vehicle body side panel 50, and the engine hood that is closed by attaching the cushion clip 10 to each mounting hole 51. 40 is elastically supported uniformly. 1 to 3, one of the mounting holes 51 described above is illustrated. Moreover, in the vehicle body side panel 50 in the present embodiment, the surface on the side where the insertion site 20 is inserted is the front surface 50b, and the opposite surface is the back surface 50a.
As well shown in FIG. 1, the mounting hole 51 of the vehicle body side panel 50 is formed with a notch portion 51 c into which an engagement portion 21 of the cushion clip 10 to be described later can be fitted at a facing position. Further, an extension portion 52 formed to extend from the attachment hole 51 to the side where the insertion portion 20 of the cushion clip 10 is inserted (on the back surface 50a side of the vehicle body side panel 50) is formed on the peripheral portion 51b of the attachment hole 51. It is provided integrally with the side panel 50. Specifically, the extension portion 52 is formed by bending a shape portion that protrudes from the peripheral portion 51 b of the attachment hole 51 into the attachment hole 51, and the cross section thereof is an arc shape along the attachment hole 51. Has been. Further, as well shown in FIG. 3, the extension portion 52 is partially bent inward in the vicinity of the center thereof, and a hooking portion 52a having a convex shape (convex shape) is formed on the inward side. ing. More specifically, the hooking portion 52a has a direction parallel to the surface 50b of the vehicle body side panel 50 at a portion on the side where the insertion portion 20 is inserted (upper side in FIG. 1) (a direction different from the insertion direction of the insertion portion 20). The support surface 52b is formed.

Next, as described above, the cushion clip 10 includes the insertion portion 20 made of synthetic resin and the rubber cushion portion 30 (both are configured to have conductivity).
Specifically, as shown in FIG. 1, the insertion site 20 has a distal end side 20 a (lower side in FIG. 1) as a joint and is directed toward the root side 20 b (upper side in FIG. 1). An engagement portion 21 having a shape protruding outward in the radial direction (a shape protruding beyond the outer diameter between the notch portions 51c of the mounting hole 51) is integrally formed. In detail, the engagement part 21 is disposed opposite to the side surface 20c of the insertion part 20, and each of them can be elastically deformed in the radial direction. Further, a locking portion 21a having a shape in which an outer edge portion is cut out in an L-shaped cross section is formed at the tip of the engaging portion 21 (upper end in FIG. 1). Specifically, the locking portion 21a forms an L-shaped cross section by a resilient contact surface 21b facing outward in the radial direction of the insertion site 20 and a pull-out preventing surface 21c facing the direction perpendicular to the resilient contact surface 21b. ing. Therefore, when the insertion part 20 is inserted into the attachment hole 51, the engagement part 21 comes into contact with the periphery of the attachment hole 51 and is subjected to radial regulation, and is once elastically constricted radially inward. As shown well in FIG. 2, when the insertion portion 20 is further inserted and the pull-out prevention surface 21c of the locking portion 21a passes through the mounting hole 51, the engagement portion 21 is released from the restriction, and the radial direction Restoring outward, the elastic contact surface 21 b of the locking portion 21 a is elastically brought into contact with the inner side surface 51 a of the mounting hole 51. In addition, the pull-out preventing surface 21c of the locking portion 21a is thereby arranged on the back surface 50a side of the vehicle body side panel 50. Therefore, when the insertion site 20 is to be pulled out and moved in the direction opposite to the insertion direction in this state, the pull-out preventing surface 21 c comes into contact with the back surface 50 a of the vehicle body side panel 50. That is, the engagement part 21 is engaged around the attachment hole 51 and the extraction part 20 is prevented from being pulled out.
Further, as shown well in FIG. 1, a seat 22 having a shape projecting radially outward of the insertion site 20 is formed on the root side 20 b (upper side in FIG. 1) of the insertion site 20. As shown well in FIGS. 2 and 3, the seat 22 has the seating surface 22 a in contact with the surface 50 b of the vehicle body side panel 50 when the insertion site 20 is inserted into the mounting hole 51. It is set as the structure which performs insertion positioning. Therefore, when the insertion portion 20 is inserted to a position where the insertion portion 20 is positioned, the seat 22 of the insertion portion 20 and the surface 50b of the vehicle body side panel 50 come into contact with each other. It will be in the contact state which can supply with electricity with the panel 50. FIG. In addition, when the load in the insertion direction is applied to the insertion site 20, the vehicle body side panel 50 in contact with the seat 22 applies a support force in the direction opposite to the load. The engaging portion 21 described above is set to engage around the mounting hole 51 at a stage immediately before the seat 22 abuts on the surface 50b of the vehicle body side panel 50. That is, the cushion clip 10 inserts the insertion site 20 into the mounting hole 51 and brings the seat surface 22a of the seat 22 into contact with the surface 50b of the vehicle body side panel 50. It will be in the attachment state by which movement of was suppressed.

Further, as well shown in FIG. 1, the diameter of the insertion portion 20 is provided on the side surface 20 c of the insertion portion 20, specifically, on both side surfaces 20 c in a direction perpendicular to the direction in which the engagement portion 21 is opposed to the aforementioned portion. A conductive elastic contact portion 23 having a shape protruding outward in the direction (a shape protruding from the inner diameter between the extension portions 52) is integrally formed. Specifically, each elastic contact portion 23 is formed in a cylindrical shape and can be elastically deformed in the radial direction of the insertion site 20. A chamfered tapered guide surface 23 a is formed at the tip of the elastic contact portion 23. Therefore, when the insertion site 20 is inserted into the mounting hole 51, the guide surface 23a is inserted into the mounting hole 51 and contacts around the mounting hole 51 to receive a radial regulating force. Thereby, the elastic contact portion 23 is elastically constricted radially inward. At this time, as shown well in FIG. 3, the elastic contact portion 23 elastically acts on the conductive extension portion 52 in order to apply the elastic force of the constricted portion outward in the radial direction. It comes into contact. Therefore, between the contact surfaces, the insertion site 20 and the vehicle body side panel 50 are in a contact state in which current can be passed.
Further, as shown well in FIG. 1, the above-described position in the root direction of the elastic contact portion 23 (position between the elastic contact portion 23 and the seat 22) is a shape (concave shape) that is concave in the radial direction of the insertion site 20. (Shape) hooked portion 24 is provided. Specifically, a seating surface 24a is formed in the hooked portion 24 in a direction parallel to the seating surface 22a of the seat 22 described above (an orientation different from the insertion direction of the insertion site 20). When the insertion portion 20 is inserted to a position where the insertion portion 20 is positioned, the engagement portion 24 is engaged with a convex engagement portion 52 a formed in the extension portion 52. Specifically, when the insertion site 20 is inserted into the attachment hole 51, the elastic contact portion 23 of the insertion site 20 is elastically constricted radially inward by the convex engaging portion 52a. When the hooking portion 52a is inserted to the position of the hooked portion 24 of the insertion site 20, the elastic contact portion 23 is restored radially outward and the support surface 52b of the hooking portion 52a is seated on the hooked portion 24. It will be in contact with surface 24a. Therefore, when the load in the insertion direction acts on the insertion site 20, the support surface 52 b of the engaging portion 52 a in contact with the seat surface 24 a applies a support force in the direction opposite to the load. That is, the extension portion 52 supports the load acting in the insertion direction of the insertion portion 20.
That is, the load in the insertion direction acting on the insertion site 20 is brought into contact with the surface 50b of the vehicle body side panel 50 brought into contact with the seat surface 22a of the seat 22 and the seat surface 24a of the hooked portion 24. And the support surface 52b of the engaging portion 52a. In addition, the insertion portion 20 is formed with respect to the vehicle body side panel 50 by the seat surface 22a of the seat 22 that contacts the surface 50b of the vehicle body side panel 50 and the elastic contact portion 23 that elastically contacts the extension portion 52. The contact state can be energized.

  Next, as is well shown in FIGS. 2 and 3, the rubber cushion part 30 includes a screw part 31 to be attached to the attachment part 25 of the insertion part 20 in a twisted state, and a closed engine. A lump-shaped receiving portion 32 that abuts on the hood 40 is integrally formed with conductivity. The cushion portion 30 can change the amount of twisting of the insertion portion 20 with respect to the mounting portion 25 by a spiral groove formed in the screw portion 31. Thereby, the protrusion amount of the cushion part 30 can be adjusted suitably. Therefore, after the cushion clip 10 with the cushion part 30 attached to the insertion part 20 is attached to the conductive vehicle body side panel 50, the amount of twisting of the cushion part 30 is changed as necessary, thereby the engine hood 40. And the receiving portion 32 can be adjusted. Thereby, the electroconductive engine hood 40 and the electroconductive cushion clip 10 can be made into the contact state which can supply with electricity.

Then, the usage method is demonstrated about the attachment structure of the cushion clip 10 of a present Example, referring FIGS. 1-3.
First, as well shown in FIG. 1, the insertion portion 20 of the cushion clip 10 is inserted into the mounting hole 51 of the vehicle body side panel 50. As a result, the engagement portion 21 and the elastic contact portion 23 are elastically constricted by the inner diameter of the mounting hole 51. When the seat 22a of the seat 22 of the insertion site 20 is inserted to a position where the seat surface 22a abuts on the surface 50b of the vehicle body side panel 50 (a position where the insertion position of the insertion site 20 is positioned), as shown in FIG. In addition, the engaging portion 21 is opened and elastically engages around the mounting hole 51. Further, as shown in FIG. 3, the elastic contact portion 23 is elastically contacted with the conductive extension portion 52 in order to apply the squeezed elastic force outward in the radial direction. It becomes a state. Therefore, the insertion portion 20 and the vehicle body side panel 50 can be energized by the contact surface between the seat 22 of the insertion portion 20 and the surface 50b of the vehicle body side panel 50 and the contact surface of the elastic contact portion 23 and the extension portion 52. It will be in a contact state (refer FIG. 3). When the insertion part 20 is inserted to a position where it is positioned, the hook part 52a of the extension part 52 is elastically hooked to the hook part 24 of the insertion part 20, and the hook part is engaged with the seating surface 24a of the hook part 24. The support surface 52b of 52a contacts. Thereby, it becomes a support structure which can support the load of the insertion direction which acts on the insertion site | part 20 with the above-mentioned surface 50b of the vehicle body side panel 50, and the support surface 52b of the engaging part 52a. Further, the movement of the insertion portion 20 in the insertion direction and the extraction direction is suppressed, and the cushion clip 10 is attached to the vehicle body side panel 50.
Next, the conductive engine hood 40 is closed with respect to the conductive vehicle body side panel 50 to which the conductive cushion clip 10 is attached. 2 and 3, the cushion portion 30 of the cushion clip 10 comes into contact with the engine hood 40, and the engine hood 40 is elastically supported so as to be energized with respect to the vehicle body side panel 50. . At this time, the load applied to the cushion part 30 acts as a load in the insertion direction of the insertion part 20. The load in the insertion direction is supported by the surface 50b of the vehicle body side panel 50 and the support surface 52b of the engaging portion 52a. Therefore, even when an excessive load is applied to the cushion clip 10 by closing the engine hood 40 with a strong force, for example, the load can be supported with a wide support area. Therefore, for example, local internal stress is not generated in a part such as the seat 22 in the insertion part 20, and a defect such as breakage is less likely to occur.

Thus, according to the mounting structure of the cushion clip 10 of the present embodiment, the support area of the cushion clip 10 with respect to the vehicle body side panel 50 can be increased to increase the support strength. Specifically, the seating surface 22a of the seat 22 of the insertion site 20 is supported by the surface 50b of the vehicle body side panel 50, and the seating surface 24a of the hooked portion 24 formed at the insertion site 20 is formed at the extension site 52. It is supported by the support surface 52b of the engaged portion 52a. Therefore, since the internal stress generated in the seat 22 of the cushion clip 10 is relieved (local stress concentration is less likely to occur), the allowable load of the entire structure can be increased. Thereby, for example, even when the engine hood 40 is closed with a strong momentum and an excessive load in the insertion direction acts on the insertion site 20, sufficient support strength can be exhibited. Further, for example, the cushioning property of the engine hood 40 can be further improved by reducing the thickness of the seat 22 and increasing the exposed height of the cushion part 30.
In addition, the above-mentioned engaging part 52a and the to-be-engaged part 24 can be provided in arbitrary positions in the form added to the structure of the conventional cushion clip 10. FIG. Therefore, the cushion clip 10 can be formed by freely setting the dimension design, the arrangement position, etc. of each part. Moreover, since the engaging part 52a and the to-be-engaged part 24 are set as the structure engaged elastically only by inserting the insertion site | part 20 in the attachment hole 51, attachment operation can be performed easily.
Furthermore, by applying the conductive cushion clip 10 having the above-described configuration to the conductive vehicle body side panel 50 and the engine hood 40, for example, a uniform space between the seat 22 and the surface 50b of the vehicle body side panel 50 is obtained. Even when the contact state cannot be obtained, a stable contact state is obtained at least between the insertion portion 20 and the extension portion 52, particularly between the elastic contact portion 23 provided in the insertion portion 20 and the extension portion 52. be able to. Therefore, the electrical conductivity of the entire structure can be improved.

Then, the attachment structure of the cushion clip 60 of Example 2 of this invention is demonstrated based on FIG.4 and FIG.5. 4 is a perspective view showing the appearance of the mounting structure of the cushion clip 60, and FIG. 5 is a cross-sectional view taken along the line CC of FIG.
Further, in the present embodiment, the description of the portions having the same configuration and operation as the mounting structure of the cushion clip 10 of the first embodiment is omitted, and the different portions will be described in detail.

As shown in FIG. 4, the cushion clip 60 of the present embodiment is inserted and fitted into a mounting hole 101 formed in a vehicle body side panel 100 (corresponding to a mounted member of the present invention) made of a steel plate. Insertion portion 70 and a cushion portion 80 that is attached to the insertion portion 70 in a twisted state and integrated. The former insertion portion 70 is inserted and fitted into the attachment hole 101 of the vehicle body side panel 100 to hold the cushion clip 60 in a state of being attached to the vehicle body side panel 100. Further, the latter cushion portion 80 is provided when the engine hood 90 (corresponding to the opening / closing lid of the present invention) made of the same steel plate that can be opened and closed with respect to the vehicle body side panel 100 is closed. The state is brought into contact with the hood 90 and elastically supported by the vehicle body side panel 100 (see FIG. 5). Unlike the first embodiment, the vehicle body side panel 100, the engine hood 90, and the like in the present embodiment are configured to have no electrical conductivity.
Hereinafter, the configuration of each unit will be described in detail.

  First, an attachment hole 101 for attaching the cushion clip 60 is formed in the vehicle body side panel 100. Further, as well shown in FIG. 4, the peripheral portion 101 b of the mounting hole 101 of the vehicle body side panel 100 is the side where the insertion portion 70 of the cushion clip 60 is inserted from the mounting hole 101 (the back surface of the vehicle body side panel 100. The extension part 102 extended and formed on the 100a side) is provided integrally with the vehicle body side panel 100. Specifically, the extension portion 102 is formed by bending a shape portion that protrudes from the peripheral portion 101 b of the attachment hole 101 into the attachment hole 101, and the cross section thereof is an arc shape along the attachment hole 101. Yes. Further, as well shown in FIG. 5, the extension portion 102 has an end portion (lower portion in FIG. 5) that is bent inward, and has a shape (convex shape) engaging portion that is convex toward the inward side. 102a is formed. More specifically, the hooking portion 102a is formed with a support surface 102b in a direction in which the bent surface is parallel to the surface 100b of the vehicle body side panel 100 (a direction different from the insertion direction of the insertion portion 70).

Next, the cushion clip 60 includes the insertion portion 70 made of synthetic resin and the cushion portion 80 made of rubber as described above.
Specifically, as shown well in FIGS. 4 and 5, the insertion portion 70 has a tapered guide surface 71 a with a chamfered tip on a side surface 70 c on the tip side 70 a (lower side in FIG. 4). The engaging part 71 is provided integrally. More specifically, the outer diameter between the engaging portions 71 is set slightly larger than the inner diameter between the engaging portions 102a of the extension portion 102 described above. In addition, a pull-out preventing surface 71 c is formed on the base side surface of the engaging portion 71. Therefore, when the insertion portion 70 is inserted into the mounting hole 101, the engagement portion 71 slides while the guide surface 71a is in contact with the convex engaging portion 102a, and is radially inward by fitting with the engaging portion 102a. It is elastically deformed due to the regulation force. Then, as shown well in FIG. 5, when the insertion portion 70 is further inserted and the pull-out preventing surface 71c of the engagement portion 71 passes through the engaging portion 102a, the engagement portion 71 is released from the restriction and is radially outside. Restore to the direction. Thereby, the pull-out preventing surface 71c of the engaging portion 71 is arranged at a position where the engaging portion 102a is present. Therefore, when the insertion portion 70 is to be pulled out and moved in the direction opposite to the insertion direction in this state, the pull-out preventing surface 71c comes into contact with the engaging portion 102a. That is, the engaging part 71 is engaged with the engaging part 102a, and the extraction part 70 is prevented from being pulled out.
Further, as well shown in FIG. 4, a seat 72 having a shape projecting radially outward of the insertion site 70 is formed on the base side 70 b (upper side in FIG. 4) of the insertion site 70. As shown well in FIG. 5, the seat 72 has the seating surface 72 a in contact with the surface 100 b of the vehicle body side panel 100 when the insertion site 70 is inserted into the mounting hole 101, and the insertion location of the insertion site 70 is determined. It is set as the structure which performs. Therefore, when the insertion part 70 is inserted to the position where it is positioned, the seat 72 of the insertion part 70 and the surface 100b of the vehicle body side panel 100 come into contact with each other. Further, the vehicle body side panel 100 in contact with the seat 72 applies a supporting force in a direction opposite to the load when a load in the insertion direction is applied to the insertion site 70. The engaging portion 71 is engaged with the engaging portion 102a before the seat 72 abuts on the surface 100b of the vehicle body side panel 100 (the pull-out preventing surface 71c of the engaging portion 71 is provided with the engaging portion 102a). It is set to be arranged at the position). That is, the cushion clip 60 inserts the insertion site 70 into the mounting hole 101 and brings the seat surface 72a of the seat 72 into contact with the surface 100b of the vehicle body side panel 100. It will be in the attachment state by which movement of was suppressed.

  Further, as well shown in FIG. 4, a shape that is concave in the radial direction of the insertion portion 70 (recessed) is formed at the position in the root direction of the engagement portion 71 (position between the engagement portion 71 and the seat 72). (Shape) hooked portion 74 is provided. Specifically, the hooked portion 74 is formed with a seat surface 74a in a direction parallel to the seat surface 72a of the seat 72 described above (an orientation different from the insertion direction of the insertion portion 70). When the insertion portion 70 is inserted to a position where the insertion portion 70 is positioned, the engagement portion 74 is engaged with a convex engagement portion 102 a formed in the extension portion 102. Specifically, as described above, when the insertion portion 70 is inserted into the attachment hole 101, the engagement portion 71 of the insertion portion 70 is elastically constricted radially inward by the convex engaging portion 102a. When the hooking portion 102 a is inserted to the position of the hooked portion 74 of the insertion portion 70, the engaging portion 71 is restored radially outward, and the support surface 102 b of the hooking portion 102 a is connected to the hooked portion 74. It will be in contact with the seat surface 74a. Therefore, when the load in the insertion direction is applied to the insertion site 70, the support surface 102b of the engaging portion 102a in contact with the seat surface 74a applies a support force in the direction opposite to the load. In other words, the extension part 102 supports the load acting in the insertion direction of the insertion part 70.

  Next, as well shown in FIG. 5, the rubber cushion portion 80 is attached to the screwed portion 81 to be attached to the mounting portion 75 of the insertion portion 70 in a twisted state, and the engine hood 90 in the closed state. A lump-shaped receiving portion 82 that abuts is integrally formed. The cushion portion 80 can change the amount of twist with respect to the mounting portion 75 of the insertion portion 70 by a spiral groove formed in the screw portion 81. Thereby, the protrusion amount of the cushion part 80 can be adjusted suitably, and the contact state of the engine hood 90 and the receiving part 82 can be adjusted.

Subsequently, the usage method of the mounting structure of the cushion clip 60 of the present embodiment will be described with reference to FIGS.
First, as well shown in FIG. 4, the insertion portion 70 of the cushion clip 60 is inserted into the mounting hole 101 of the vehicle body side panel 100. Thereby, the engagement part 71 is elastically constricted by the inner diameter of the engaging part 102a of the extension part 102. When the seat 72 of the insertion portion 70 is inserted to a position where the seat 72 contacts the surface 100b of the vehicle body side panel 100 (position where the insertion position of the insertion portion 70 is positioned), as shown in FIG. The part 71 is elastically opened and engages with the engaging part 102a. At the same time, the engaging portion 102a is elastically engaged with the engaged portion 74 of the insertion site 70. As a result, the support surface 102 b of the hooking portion 102 a comes into contact with the seat surface 74 a of the hooked portion 74. That is, it becomes a support structure capable of supporting the load in the insertion direction acting on the insertion site 70 by the surface 100b of the vehicle body side panel 100 and the support surface 102b of the engaging portion 102a. In this way, the insertion portion 70 is prevented from moving in the insertion direction and the extraction direction, and the cushion clip 60 is attached to the vehicle body side panel 100.

  As described above, according to the mounting structure of the cushion clip 60 of the present embodiment, the pull-out preventing surface 71c can be engaged with the engaging portion 102a of the extension portion 102, whereby the pull-out of the insertion portion 70 can be performed. The movement can be prevented. That is, it is configured to have both a function of supporting the load in the insertion direction of the insertion part 70 at the extension part 102 and a function of maintaining the state where the insertion part 70 is inserted and fitted into the mounting hole 101.
