However, the holding structure as described in Patent Document 1 is suitable for holding an intermediate portion of the linear member because the linear member is locked by the notch portion and the locking portion. It was not suitable for fixing the ends of wires such as harnesses, particularly the ends provided with the components, so that they do not move freely.
In some cases, electronic components must be disposed near the vehicle body. In such a case, conventionally, in order to protect the electronic component from external impact, a protector surrounding the electronic component is provided, and the protector is fixed to a counterpart such as a body by fixing brackets, welding, screws, or the like. doing. In this case, the protector is required to have high rigidity, and not only a space for attaching the protector is required, but also the protector must be mechanically fixed by a fixing bracket or welding.

  The present invention has been made in view of the above circumstances, and provides a component fixing structure for easily fixing a component provided at one end of a wire to an interior member without falling off and being damaged. Objective.

In order to solve the above-described problem, the first invention is provided on an interior member that faces the inner surface of a vehicle body, and abuts on or is fixed to the body to regulate a change in the interval between the interior member and the body. A component fixing structure for fixing a component provided at one end of a wire to a boss, wherein one side surface of the boss is opened to form a bottomed hole, and the component is It is disposed in a hole, is fixed by a buffer sheet that is sandwiched between the inner surface of the bottomed hole and the surface of the component and is compressed, and the wire extends out of the opening. The gist.
The gist of a second invention is that, in the first invention, the component is inserted and fixed in the bottomed hole in a state in which the buffer sheet is wound around in advance.
The gist of a third invention is that, in the first or second invention, the component is an electronic component provided at one end of a wire of a wire harness.

According to the component fixing structure of the present invention, one end of the wire is attached to the boss that is erected on the interior member facing the inner surface of the vehicle body and that abuts or is fixed to the body to regulate the change in the distance between the interior member and the body. The boss has a bottomed hole formed by opening one side surface of the boss, and the part is disposed in the bottomed hole. Are fixed by a buffer sheet that is sandwiched and compressed between the inner surface of the component and the surface of the component, and the wire extends out from the opening, so that the component and the component do not fall out of the bottomed hole. The wire can be fixed. As a result, the end of the component and the wire are fixed so as not to freely move, and the end of the component and the wire are not worn by rubbing against the interior member or the body or generating an abnormal noise. it can.
Moreover, the fixing member and boss | hub of a component can be united, without providing the protector etc. which are covered or fitted in order to fix a component separately. For this reason, it is not necessary to secure a place for providing a protector or the like, and a separate structure such as a bracket is not necessary for fixing, and it is not necessary to mechanically fix by welding or the like. Further, since the component is fixed by interposing a buffer sheet in the opening of the boss for regulating the interval between the interior member and the body so as not to change, even if a large force is applied to the interior member, the force is applied to the component itself. It can be made difficult to join, and parts can be prevented from breaking.

  The items shown here are for illustrative purposes and exemplary embodiments of the present invention, and are the most effective and easy-to-understand explanations of the principles and conceptual features of the present invention. It is stated for the purpose of providing what seems to be. In this respect, it is not intended to illustrate the structural details of the present invention beyond what is necessary for a fundamental understanding of the present invention. It will be clear to those skilled in the art how it is actually implemented.

  The component fixing structure according to the present embodiment is provided at one end of a wire (31) on a boss (11) standing on an interior member (71) facing the inner surface of a body (81) of an arbitrary vehicle such as a passenger car. The boss (11) has a bottomed hole (15) formed by opening one side surface of the boss (11), and the part (21) has a bottomed hole (15). ) And is fixed by a buffer sheet (41) which is sandwiched between the inner surface of the bottomed hole (15) and the surface of the component (21) and is compressed, and the wire (31) extends from the opening. It is characterized by extending outward (see FIGS. 1 and 2).

  The boss (11) only needs to be a member that regulates a change in the distance between the body (81) and the interior member (71) that are arranged to face each other with a predetermined interval, and is in contact with the body (81). Thus, it may be a contact boss that restricts the interval from becoming narrower (see FIG. 2), or a boss that can keep the interval constant by screws, clips, or the like. The distance between the body (81) and the interior member (71) is not particularly limited. The boss (11) is erected substantially perpendicular to the interior member (71).

  As for the shape of the boss (11), it suffices if one side surface thereof is opened to form a bottomed hole (15). Moreover, the bottomed hole (15) should just be a shape and a magnitude | size which can accommodate the components (21) to fix. Moreover, when the component (21) is fixed with the buffer sheet (41) interposed, a gap (18) may be partially formed (see FIGS. 2 and 5). For example, as shown in FIGS. 1 and 2, the component (21) is sandwiched via the cushioning sheet (41) in the direction parallel to the interior member (71), and the cushion is disposed in the direction perpendicular to the interior member (71). There may be a gap (18) between the sheet (41) or component (21) and the inner surface of the bottomed hole (15). In addition, the component (21) is sandwiched via the cushioning sheet (41) in a direction perpendicular to the interior member (71), and in the direction parallel to the interior member (71), the cushioning sheet (41) and the component (21). There may be a gap between the bottom surface and the inner surface of the bottomed hole (15).

  The types of the wire (31) and the component (21) are not particularly limited, and examples thereof include an electronic component provided on a wire such as a wire harness and a cap provided on a power transmission wire. Moreover, the electronic component can exemplify a module containing an arbitrary circuit such as a battery or a filter in addition to passive elements such as a capacitor and a coil. Furthermore, the component (21) may be directly connected to the wire (31), or may be connected via a coupler (for example, the coupler 35 shown in FIG. 2), a connector, or the like.

  The buffer sheet (41) is interposed between the inner surface of the bottomed hole (15) and the component (21) in a crushed state, and can be compressed so that the component (21) does not fall off due to the repulsive force. Any sheet may be used. Examples of the material of the buffer sheet (41) include a foam-formed body such as a resin foam and an elastic body such as an elastomer (rubber or the like). In addition, the buffer sheet (41) may have a flat sheet shape, a cylindrical shape, a bag shape, and the like. By inserting such a buffer sheet (41) into the bottomed hole (15) in a state of being wrapped around or wrapped around the part (21), the part (21) is inserted into the bottomed hole (15). Can be fixed to.

The component fixing structure according to the present embodiment will be specifically described with reference to FIGS. 1 and 2 show a fixing structure in which a component 21 around which a buffer sheet 41 is wound is inserted and fixed in a bottomed hole 15 of a contact boss 11 formed integrally with an interior member 71.
The interior member 71 is a plate-like member such as various trims and package trays, and is made of resin, fiber mixed resin, or the like. The number of the contact bosses 11 provided on the interior member 71 is not particularly limited. Further, it is sufficient that the bottomed hole 15 is formed only in the contact boss 11 where the component 21 is to be disposed.

  As shown in FIGS. 2, 3, and 4, the abutting boss 11 includes a quadrangular frustum-shaped base portion 12 whose bottom surface is integrated with the interior member 71, and a cylindrical head erected on the top surface portion of the base portion 12. Unit 13. The base 12 is provided with ribs 14 provided so as to divide the internal space vertically. One side of the base portion 12 is opened, and the space defined as described above is connected to the outside to form bottomed holes 15 and 16, respectively. In this example, as shown in FIGS. 2 and 5, the component 21 is inserted and fixed in the bottomed hole 15 on the lower side (interior member 71 side). 21 may be inserted and fixed.

  In this example, the component 21 is a capacitor which is a square electronic component as shown in FIGS. Two wires 32 are connected to the electrodes of the capacitor. The component 21 is connected to the wire 31 of the wire harness via the coupler 35. Note that the wire 31 includes two conductors and is connected to the two wires 32, respectively.

  The buffer sheet 41 is made of a strip-shaped resin foam having a thickness of about 10 mm, and is provided so as to be wound around the peripheral surface of the component 21 as shown in FIGS. The buffer sheet 41 is compressed by the component 21 and the bottomed hole 15 until the thickness of the buffer sheet 41 is approximately halved (see reference numeral 41a in FIGS. 6 and 7). 15 is fixed.

In the present embodiment, a procedure for arranging and fixing the component 21 in the bottomed hole 15 of the contact boss 11 will be described. As shown in FIG. 6, the component 21 is attached to the tip of the wire 31, and a buffer sheet 41 is wound around the component 21. The buffer sheet 41 may be attached to the component 21.
Next, after the buffer sheet 41 is crushed and contracted to a size that allows insertion into the bottomed hole 15, the component 21 is inserted into the bottomed hole 15. The component 21 inserted into the bottomed hole 15 is fixed to the bottomed hole 15 with the surface of the buffer sheet 41 extending to the side surface of the bottomed hole 15.

  As shown in FIGS. 1, 3 and 5, in the present embodiment, the surface of the buffer sheet 41 is integrated with the inner surface of the base 12 located in the left-right direction (horizontal direction with the interior member 71), and the interior member 71. Although it is in contact with the bottom surface, it is not in contact with the upper rib 14 and a gap 18 is formed. Even when such a gap 18 is in the vertical direction of the component 21 (perpendicular to the interior member 71), the inner surface of the base portion 12 in the left-right direction of the component 21 contacts the compressed cushioning sheet 41 to fix the component 21. Therefore, the component 21 does not fall off the component 21. Further, the surface of the buffer sheet 41 may be brought into contact with the rib 14 by using the contact boss 11 in which the position of the rib 14 is shifted downward or by changing the thickness of the buffer sheet 41. Furthermore, the left and right and upper and lower surfaces of the buffer sheet 41 may be in contact with the inner surface of the bottomed hole 15.

In such a component fixing structure, the component 21 is fixed without being easily removed from the bottomed hole 15 by the restoring force of the buffer sheet 41. For this reason, the end portions of the component 21 and the wire 31 do not move freely, and it can be prevented from being worn by rubbing against the interior member 71 and the body 81 or generating abnormal noise. Further, the component 21 can be fixed without mechanical fixing such as welding.
Moreover, in order to arrange the component 21 around which the buffer sheet 41 is wound in the bottomed hole 15 of the base 12 of the contact boss 11 that is firmly formed in order to keep the interval between the interior member 71 and the body 81 constant, Even if the interior member 71 is pressed toward the body 81, the component 12 can be protected without applying force to the component 21 by the base 12 and the buffer sheet 41. For this reason, a separate protector etc. are unnecessary.

The present invention is not limited to the embodiment described above, and various modifications can be made within the scope of the present invention depending on the purpose and application.
In the component fixing structure of the present embodiment, the head 13 is in contact with the body 81 and uses the abutting boss 11 that is not fixed. However, the present invention is not limited to this, and the head 13 may be fixed to the body 81 with screws, clips, or the like. Good. The component 21 is not limited to a capacitor, and may be a module or the like in which an arbitrary circuit such as a filter is stored in addition to an element such as a coil.
