Description

  The present invention relates to a wire harness fixing structure in which an exterior of one or a plurality of conductive paths is covered with a tubular body, and a wire harness fixing method.

  Generally, it is necessary to protect one or a plurality of conductive paths from impacts such as stepping stones in a wire harness routed on an outer periphery of a vehicle body such as an automated person (for example, an externally exposed part such as a vehicle body floor). Therefore, the exterior of the conductive path is covered with a tubular body.

  In order to fix such a wire harness to the outer periphery of the vehicle body, for example, there is a wire harness fixing structure that fixes the wire harness to the outer periphery of the vehicle body by a clamp made up of a pair of halved members that can be opened and closed. It is known (see, for example, Patent Document 1). In this technique, the tube body can be held in an arbitrary shape by a support member attached to the clamp.

JP 2009-38899 A (2nd to 4th pages, FIGS. 1 and 2)

  However, in the conventional wire harness fixing structure described above, since the clamp is formed by a pair of halved members connected to be openable and closable, there is a limit to miniaturization and weight reduction of the clamp.

  In addition, the conventional wire harness fixing structure requires various sizes of clamps and support members depending on the diameter and shape of the wire harness, and requires a support member separately from the clamps, which increases the number of parts. Will be invited. Therefore, the conventional wire harness fixing structure has a problem that the manufacturing cost such as design cost and material cost increases.

  Then, this invention aims at provision of the fixing structure of a wire harness and the fixing method of a wire harness which can implement | achieve space saving and weight reduction, suppressing manufacturing cost.

  According to this feature, the vehicle body fixing member can be fixed to the outer periphery of the tube body only by using a long curable member without using a clamp as in the prior art, so that space saving and weight reduction can be realized. Further, when the vehicle body fixing member is fixed to the outer periphery of the tubular body by the curable member, the tubular body can be held in an arbitrary shape by the curing action of the curable member. In other words, since the tube body can be held in any shape with only the curable member, the clamps and support members of various sizes can be used depending on the diameter and shape of the wire harness as in the past, regardless of the diameter and shape of the wire harness. Can be eliminated and the number of parts can be reduced. In addition, a general inexpensive vehicle body fixing member can be used without specially designing the vehicle body fixing member. Therefore, manufacturing costs such as design costs and material costs can be reliably suppressed.

  A second feature of the present invention relates to the first feature of the present invention, wherein the vehicle body fixing member is coupled to a clip body portion (clip body portion 210) that engages with the vehicle body, and the clip body portion. An attachment fixing part (attachment fixing part 220) along the outer periphery of the tubular body is provided, and the attachment fixing part is fixed to the outer periphery of the tubular body by the curable member.

  According to such a feature, the vehicle body fixing member is provided with the mounting and fixing portion along the outer periphery of the tubular body, thereby saving space compared to the case where the mounting and fixing portion not along the outer periphery of the tubular body is provided. Can be realized. Further, since the tube body can be easily held in an arbitrary shape by the mounting and fixing portion along the outer periphery of the tube body, the mounting operation of the vehicle body fixing member can be performed accurately and easily, and the strength of the tube body can be ensured.

  A third feature of the present invention relates to the second feature of the present invention, wherein the surface of the curable member has adhesiveness, and the attachment fixing portion is attached in advance to the outer periphery of the tubular body. The gist is to be temporarily fixed to the outer periphery of the tubular body by being adhered to the surface of the curable member.

It becomes.

  A fourth feature of the present invention is that the wire harness is fixed to the outer periphery of the vehicle body by a vehicle body fixing member that can fix the exterior of one or a plurality of conductive paths with a tubular body to the vehicle body. In the state in which the vehicle body fixing member is in contact with the outer periphery of the tubular body, a long shape that is cured with water or light at an outer peripheral position corresponding to a contact portion between the vehicle body fixing member and the tubular body. The gist includes at least a step of winding the curable member (main winding step) and a step of curing the curable member attached to the outer peripheral position (main fixing step).

  A fifth feature of the present invention relates to the fourth feature of the present invention, wherein the vehicle body fixing member is in contact with the outer periphery of the tubular body before the step of winding the curable member around the outer peripheral position. The gist further includes a step of temporarily fixing the vehicle body fixing member to the outer periphery of the tubular body (temporary fixing step).

  According to the feature of the present invention, since the vehicle body fixing member can be fixed to the outer periphery of the tube body only with the long curable member, the wire harness can be fixed while reducing the manufacturing cost and realizing space saving and weight reduction. A structure and a method for fixing a wire harness can be provided.

(2) Configuration of Wire Harness 100 Next, the configuration of the wire harness 100 according to the present embodiment will be described with reference to FIG. FIG. 2 is a perspective view showing the wire harness 100 according to the present embodiment.

  Here, as described above, the intermediate portion 100M of the wire harness 100 is routed substantially parallel along the vehicle body underfloor 11 (see FIG. 1). That is, the middle part 100M of the wire harness 100 is routed so as to earn a distance from the ground. The wire harness 100 is manufactured with a structure that is reduced in height to increase the distance from the ground.

  As shown in FIG. 2, in the wire harness 100, the exterior of one or a plurality of conductive paths 111 is covered with a tubular body 120. Specifically, the wire harness 100 includes a conductive path assembly 110 and a tube body 120 that covers the exterior of the conductive path assembly 110 (conductive path 111).

(2-1) Configuration of Conductive Path Assembly 110 The conductive path assembly 110 includes one or a plurality of conductive paths 111 and an electromagnetic shield member 112 that collectively shields the conductive paths 111. In the present embodiment, the conductive path 111 is constituted by one high-voltage electric wire 111A and two low-voltage electric wires 111B.

  The high voltage electric wire 111A is a conductive path including a conductor and an insulator (coating), and has a length necessary for electrical connection. The conductor is made of copper, a copper alloy, aluminum, an aluminum alloy, or the like. Concerning the conductor, a conductor structure in which strands are twisted together or a rod-shaped conductor structure having a rectangular or round cross section (for example, a conductor structure having a flat single core or a round single core. It may be any of those in the form of a rod. The high voltage electric wire 111A has a configuration to be an unshielded electric wire. Note that connectors (not shown) are provided at both ends of the high voltage electric wire 111A.

  Here, although the high voltage electric wire 111 </ b> A has been described as being used in the wire harness 100 in the present embodiment, the present invention is not limited to this. For example, a well-known bus bar provided with an insulator in the wire harness 100 may be used.

  The low voltage electric wire 111B may be any known one. In the present embodiment, the low voltage electric wire 111 </ b> B has been described as being included in the configuration of the conductive path assembly 110, but is not limited thereto. In other words, whether or not the conductive path assembly 110 is included in the conductive path assembly 110 is arbitrary.

  The electromagnetic shield member 112 is an electromagnetic shield member (electromagnetic wave countermeasure member) that collectively covers the high-voltage electric wire 111A and the low-voltage electric wire 111B, and is used as a shield member including a conductive metal foil or a metal foil alone. It is formed in a cylindrical shape. The electromagnetic shield member 112 is formed to have substantially the same length as the entire length of the high voltage electric wire 111A. The electromagnetic shield member 112 is connected to a shield case or the like of the inverter unit 4 via a connector (not shown) provided at the end of the high voltage electric wire 111A.

  In the present embodiment, the electromagnetic shielding member 112 has been described as including a metal foil, but is not limited thereto. In other words, the electromagnetic shield member 112 only needs to be able to take countermeasures against electromagnetic waves. For example, a braid that has a large number of ultrafine wires and has conductivity and is formed in a cylindrical shape may be used.

(2-2) Configuration of Pipe Body 120 The pipe body 120 covers the exterior of the conductive path assembly 110 (conductive path 111). The tube body 120 has flexibility and is formed in a cross-sectionally long shape. It is preferable that the outer peripheral surface of the tubular body 120 has irregularities. In this embodiment, a resin corrugated tube (bellows tube) having a concavo-convex outer peripheral surface, a so-called flat corrugated tube is used for the tubular body 120.

  The corrugated tube used for the tubular body 120 is not only a structure effective for reducing the weight, but also the above-described structure for reducing the height, that is, an effective structure for obtaining a distance from the ground. Particularly, it is preferable that the corrugated tube has no slit and the outer peripheral surface is formed watertight.

  In addition, although the corrugated tube which has an unevenness | corrugation on an outer peripheral surface was used for the tubular body 120, it demonstrated, but it is not limited to this. For example, the tubular body 120 may be a metallic tube having a concavo-convex shape on the outer peripheral surface (a bellows tube), or a tube made of resin or rubber having no concavo-convex on the outer peripheral surface. Further, the tube body 120 is not limited to a horizontally long cross section, and may have a circular cross section, a quadrangular cross section, or the like.

(3) Description of Wire Harness Fixing Structure 10 Next, details of the wire harness fixing structure 10 according to the present embodiment will be described with reference to FIGS. FIG. 3 is an exploded perspective view showing the wire harness fixing structure 10 according to the present embodiment.

  As shown in FIGS. 2 and 3, the wire harness fixing structure 10 is a structure in which the above-described wire harness 100 is fixed to the outer peripheral portion (the vehicle body floor bottom 11) of the vehicle body 1 by a vehicle body fixing member 200 that can be fixed to the vehicle body 1. It is. At this time, in the wire harness fixing structure 10, a long curable member 300 that is cured by water or light is used.

(3-1) Configuration of the Car Body Fixing Member 200 The car body fixing member 200 is used when the wire harness 100 (for example, the intermediate portion 100M) is routed in the vehicle body underfloor 11. The vehicle body fixing member 200 is provided at a plurality of predetermined portions of the tube body 120.

  Here, since the vehicle body fixing member 200 is a predetermined portion indicated by an arrow A and an arrow B shown in FIG. 1, that is, a flexible tubular body 120, in addition to the intermediate portion 100 </ b> M of the wire harness 100, the wire harness 100. This is provided at a portion where shape retention is required, such as a bent portion or an assembly fixing portion. Hereinafter, an example in which the vehicle body fixing member 200 is provided in the intermediate portion 100M of the wire harness 100 will be described.

  The vehicle body fixing member 200 includes a clip main body portion 210 and an attachment fixing portion 220. The clip main body portion 210 engages with a through hole (not shown) formed in the vehicle body underfloor 11. The attachment fixing portion 220 is connected to the clip main body portion 210 and is fixed to the outer periphery of the tube body 120 along the tube body 120 by the curable member 300. The attachment fixing portion 220 has a plate shape and is formed in a substantially T shape in a top view.

  Note that, when the attachment fixing portion 220 is provided at the bent portion of the wire harness 100, the attachment fixing portion 220 does not necessarily have a flat shape, and is formed, for example, in an arc shape or a substantially L shape along the bent portion. It may be.

  Here, the attachment fixing portion 220 may be temporarily fixed to the outer periphery of the tube body 120 by being adhered to the curable member 300 previously attached to the outer periphery of the tube body 120. Details of this will be described later (see FIG. 4).

(3-2) Configuration of Curable Member 300 The curable member 300 is used when the wire harness 100 is fixed to the vehicle body fixing member 200. The curable member 300 is cured by water (for example, injection / dropping of water or immersion in water) or light (for example, visible light or dedicated illumination). The curable member 300 has a long shape, that is, a tape shape.

  The curable member 300 includes a surface cured portion 301 that is cured by water or light, and a back substrate portion 302 that is integrated with the surface cured portion 301 and has adhesiveness. The front hardened portions 301 are held together by impregnating the back substrate portion 302.

  When the curable member 300 is cured by water, the surface cured portion 301 is formed by a water curable resin composition. On the other hand, when the curable member 300 is cured by light, the surface cured portion 301 is formed of a photocurable resin composition.

  For example, as the surface hardening portion 301, a water curable urethane resin or the like can be used. On the other hand, examples of the back substrate portion 302 include glass wool, glass cloth, polyester cloth, and nonwoven fabric. In addition, knit weave is suitable for impregnation of glass cloth and polyester cloth, and uniform impregnation can be achieved.

  The curable member 300 is preferably a member that can be adjusted such that the curing time is immediate curing or slow curing. Further, the curable member 300 is particularly effective in a working environment that dislikes moisture (the moisture in the use environment is not problematic).

  Here, the surface cured portion 301 (the surface of the curable member 300) is not only cured by water or light, but may have adhesiveness in addition to the curing action. In this case, the outer periphery of the tubular body 120 can be temporarily fixed to the surface of the curable member 300 (that is, the surface cured portion 301) by attaching the curable member 300 to the outer periphery of the tubular body 120 in advance.

(4) Description of Fixing Method of Wire Harness Next, details of the fixing method of the wire harness according to the present embodiment will be described with reference to FIG. FIG. 4 is a schematic diagram for explaining the wire harness fixing method according to the present embodiment.

  The wire harness fixing method is a method of fixing the above-described wire harness 100 to the outer periphery of the vehicle body 1 by the vehicle body fixing member 200. The fixing method of the wire harness includes a base winding step, a tube bonding step, a temporary fixing step, a main winding step, and a main fixing step.

  First, in the base winding process, the back base material portion 302 is the inner periphery side and the surface hardening portion 301 is the outer periphery side (surface) at the outer periphery position of the tube body 120 corresponding to the place where the vehicle body fixing member 200 and the tube body 120 are expected to contact. The curable member 300 is wound so as to be side. The surface of the curable member 300 (that is, the surface cured portion 301) has adhesiveness.

  Here, in the base winding step, it is not always necessary to use the curable member 300, and for example, a known tape having a sticky surface may be used.

  Next, in the tubular body bonding step, as shown in FIG. 4A, the vehicle body fixing member 200 that can be fixed to the vehicle body 1 (the vehicle body under floor 11) around the outer peripheral surface of the tubular body 120 around which the curable member 300 is wound. Glue.

  Next, in the temporary fixing step, as shown in FIG. 4B, before the main winding step, the vehicle body fixing member 200 and the tube are bonded with the vehicle body fixing member 200 adhered (contacted) to the outer periphery of the tube body 120. The vehicle body fixing member 200 is temporarily fixed to the outer periphery of the tubular body 120 by winding a temporary fixing tape 400 (for example, vinyl tape) around the outer peripheral position corresponding to the contact point with the body 120.

  Next, in the main winding process, as shown in FIG. 4C, in the state where the vehicle body fixing member 200 is in contact (adhesion) with the outer periphery of the tube body 120, the contact portion between the vehicle body fixing member 200 and the tube body 120 is formed. The curable member 300 is wound around the corresponding outer peripheral position so that the back base material portion 302 is on the inner peripheral side and the front hardened portion 301 is on the outer peripheral side (front side). That is, in the main winding process, the curable member 300 is wound around the outer periphery of the temporary fixing tape 400 in a state where the vehicle body fixing member 200 is temporarily fixed to the outer periphery of the tubular body 120 by the temporary fixing tape 400.

  At this time, the strength of the tubular body 120 can be ensured by forming the curable member 300 in a desired thickness in advance or winding the curable member 300 on the outer periphery of the tubular body 120 until the desired thickness is obtained. At the same time, the tubular body 120 can be held in a desired shape.

  Next, in the main fixing step, the curable member 300 attached to the outer peripheral position is cured with water or light. The means for supplying water or light to the curable member 300 may be portable or may be installed in advance at the manufacturing site.

  Thereafter, the wire harness 100 (wire harness fixing structure 10) in which the vehicle body fixing member 200 is fixed to the outer periphery of the tubular body 120 by the curable member 300 is transported to an automobile manufacturer or the like, for example, via the vehicle body fixing member 200. Thus, it is fixed to the vehicle body underfloor 11.

  Here, although the fixing method of the wire harness has been described as including the base winding step, the tube body bonding step, the temporary fixing step, the main winding step, and the main fixing step, the method is not limited thereto. It is sufficient that at least the main winding step and the main fixing step are included.

(5) Action / Effect In the present embodiment described above, the vehicle body fixing member 200 can be fixed to the outer periphery of the tubular body 120 only by the long curable member 300 without using a conventional clamp. Space and weight can be realized. In addition, when the vehicle body fixing member 200 is fixed to the outer periphery of the tubular body 120 by the curable member 300, the tubular body 120 can be formed into an arbitrary shape (for example, a linear shape, an arc shape, or a substantially L shape) by the curing action of the curable member 300. Shape). That is, since the tubular body 120 can be held in an arbitrary shape only by the curable member 300, the clamps of various sizes can be used depending on the diameter and shape of the wire harness as in the past without depending on the diameter and shape of the wire harness 100. In addition, the support member is not necessary, and the number of parts can be reduced. Further, a general inexpensive vehicle body fixing member 200 can be used without designing the vehicle body fixing member 200 exclusively. Therefore, manufacturing costs such as design costs and material costs can be reliably suppressed.

  In the present embodiment, the vehicle body fixing member 200 is provided with the mounting and fixing portion 220 along the outer periphery of the tube body 120, so that the mounting and fixing portion 220 not along the outer periphery of the tube body 120 is provided. Space saving can be realized. Furthermore, since it becomes easy to hold the tubular body 120 in an arbitrary shape by the mounting and fixing portion 220 along the outer periphery of the tubular body 120 (in the embodiment, it is easy to hold the tubular body 120), the mounting work of the curable member 300 is facilitated. While being accurate and easy, the strength of the tubular body 120 can be secured.

  In the present embodiment, the mounting and fixing portion 220 is temporarily fixed to the outer periphery of the tube body 120, so that the displacement between the mounting and fixing portion 220 and the outer periphery of the tube body 120 hardly occurs, and the mounting work of the curable member 300 is further performed. Accurate and easy.

  In this embodiment, it is preferable that the outer peripheral surface of the tubular body 120 has irregularities. According to this, when the curable member 300 is cured, the curable member 300 enters the concave portion on the outer periphery of the tubular body 120 and is also caught by the convex portion. For this reason, the displacement between the mounting and fixing portion 220 and the outer periphery of the tube body 120 is less likely to occur, and the tube body 120 is easily held in an arbitrary shape. This is particularly effective when the adhesive force on the outer periphery of the pipe body 120 to which the curable member 300 is attached is weak (for example, olefin resin).

  In the present embodiment, the wire harness fixing method includes the main winding step and the main fixing step, so that the vehicle body fixing member 200 is hardened to the outer periphery of the tube body 120 without using a conventional clamp. Since it can fix only with the property member 300, space saving and weight reduction are realizable. Further, in the main fixing step, when the outer periphery of the tube body 120 is fixed to the vehicle body fixing member 200 by the curable member 300, the tube body 120 can be held in an arbitrary shape by the curing action of the curable member 300. Thereby, the number of parts can be reduced without being influenced by the diameter and shape of the wire harness 100. Further, a general inexpensive vehicle body fixing member 200 can be used without designing the vehicle body fixing member 200 exclusively. Therefore, manufacturing costs such as design costs and material costs can be reliably suppressed.

  In this embodiment, the fixing method of the wire harness includes the base winding step, the tube body bonding step, and the temporary fixing step, so that the displacement between the mounting and fixing portion 220 and the outer periphery of the tube body 120 hardly occurs. Since there is no need to press the vehicle body fixing member 200 on the outer periphery of the body 120, and the attaching operation of the curable member 300 becomes more accurate and easy, the productivity can be improved.

  For example, the embodiment of the present invention can be modified as follows. Specifically, the curable member 300 has been described as being used when the vehicle body fixing member 200 is fixed to the outer periphery (wire harness 100) of the tubular body 120, but is not limited thereto. For example, the curable member 300 may be cured in advance by bending the tubular body 120 around the tubular body 120 at the curved portion of the wire harness 100 (arrow A or arrow B in FIG. 1A). Thereafter, the curable member 300 is wound around the outer periphery of the bent portion with the vehicle body fixing member 200 in contact with the outer periphery of the tube body 120. Thereby, the strength of the bent portion can be further improved.

  In addition, the shape of the bent portion of the wire harness 100 provided with the curable member 300 (arrow A or arrow B in FIG. 1A) may be simply a bent shape or a twisted shape or plane. Of course, the shape may be a substantially S-shape, a crank shape, or the like, and it is a matter of course that the curable member 300 only needs to be able to cure the tubular body 120 at the bent portion of the wire harness 100.

  In addition, the vehicle body fixing member 200 has been described as including the clip main body portion 210 and the attachment fixing portion 220. However, the vehicle body fixing member 200 is not limited to this and may be any known member. For example, the vehicle body fixing member 200A may have a clip shape by hand tightening as shown in FIG. In this case, the wire harness fixing method may not include the base winding step, the tube body bonding step, and the temporary fixing step.

  Moreover, although this fixing process was demonstrated as what is performed at a manufacturing field, it is not limited to this, For example, you may be performed by the automobile manufacturer. Thereby, the pipe body 120 can be formed into a desired shape according to various sizes of automobiles such as the shape and size of the automobile.
