Description

  The present invention mainly relates to a harness protector that protects a wire harness arranged linearly on a vehicle body.

  In an electric vehicle or a hybrid vehicle, a battery, an inverter, a motor, and the like are connected by a high-voltage wire harness (high-voltage harness). The high-voltage wire harness is arranged linearly under the floor (outer bottom surface) of the vehicle body.

  Moreover, it is necessary to protect the wire harness arrange | positioned under the floor of a vehicle body from the stone which jumped from the road. Patent document 1 discloses the structure which protects a wire harness with metal pipes. Metal pipes are often used for high-voltage wire harnesses because they are sturdy and can be shielded.

  Patent Documents 2 and 3 disclose a harness protector composed of a plurality of blocks. Since each block is rotatably connected, the harness protector can be bent.

  Here, the wire harness is housed and shipped in a packaging box with the harness protector attached. Therefore, when protecting a wire harness with a metal pipe like patent document 1, since a metal pipe cannot be bent, a packing form (packing form) becomes large. In particular, when the wire harness is arranged in a straight line, the package shape is further increased.

  The harness protectors of Patent Documents 2 and 3 can be housed in a packaging box in a bent state. However, the wire harnesses of Patent Documents 2 and 3 are configured to be attached to the vehicle body in a bent state. Therefore, when this type of harness protector is applied to a wire harness arranged in a straight line, the harness protector may be bent during or after attachment to the vehicle body, and a load may be applied to the wire harness.

  The present invention has been made in view of the above circumstances, and its main purpose is to provide a harness protector that protects a wire harness arranged in a straight line on the vehicle body. An object of the present invention is to provide a configuration that achieves both protection of a wire harness.

Means and effects for solving the problems

  The problems to be solved by the present invention are as described above. Next, means for solving the problems and the effects thereof will be described.

  According to an aspect of the present invention, a harness protector having the following configuration is provided. That is, the harness protector is configured by protecting a portion of the wire harness attached to the vehicle body arranged in a straight line and connecting a plurality of blocks covering the periphery of the wire harness. The block includes a connecting portion and a rotation restricting portion. The said connection part connects another block rotatably. The rotation restricting portion rotates the other block to the other side without restricting the rotation when the other block is rotated to the one side in a state of being linearly connected to the other block. In some cases, the rotation is restricted by contacting the other block.

  Thereby, since a harness protector can be bent by rotating a block to one side, it can accommodate compactly. Moreover, since the rotation of the other side of the block is restricted, it is possible to prevent the harness protector attached in a straight line from bending at least to the other side.

  In the harness protector, it is preferable to restrict the rotation when the other block is rotated in a direction away from the vehicle body.

  As a result, after attachment to the vehicle body, rotation on one side of the block is regulated by the vehicle body, and rotation on the other side of the block is regulated by the rotation regulating unit, so that the harness protector attached in a straight line is bent. Can be prevented.

  In the harness protector, when the other block is rotated to the one side, the block is pushed by the other block, thereby covering the boundary with the other block and the other block. It is preferable to provide a rotating boundary protection part.

  Thereby, at the time of accommodation and attachment, a wire harness can be protected more reliably.

  The harness protector preferably has the following configuration. That is, the connecting portion is a long hole whose longitudinal direction coincides with the wire harness or a convex portion protruding in the rotation axis direction of the block. The block and the other block are connected by a long hole and a convex portion inserted into the long hole.

  Thereby, since a block can be moved along the longitudinal direction of a wire harness, it can attach to a vehicle body reliably and easily, suppressing the dimensional accuracy of a harness protector.

  The harness protector preferably has the following configuration. That is, the block includes a first protection member and a second protection member. The first protective member faces the vehicle body after being attached to the vehicle body. The second protective member is disposed to face the first protective member, the wire harness is disposed between the second protective member and the first protective member, and includes the rotation restricting portion.

  Thereby, since a block is a division structure, the operation | work which arrange | positions a wire harness in a harness protector can be simplified.

  In the said harness protector, it is preferable that the said rotation control part covers the outer side of a connection location with the said other block.

  Thereby, a rotation control part can be comprised with a simple shape. In addition, since the internal wire harness is not easily exposed when the harness protector is bent, the rotation restricting portion can more reliably protect the wire harness.

  The harness protector preferably has the following configuration. That is, the second protection member includes the connecting portion. The first protection member includes a lock portion that locks the second protection member and the other block so as not to be disconnected.

  Thereby, since it becomes difficult to remove | deviate connection of blocks, the tolerance to external force can be improved.

  The harness protector preferably has the following configuration. That is, a plurality of first recesses are formed in the first protection member. A plurality of second recesses are formed in the second protection member. A band for holding the wire harness in the block is inserted into a hole formed by combining the first recess and the second recess.

  Thereby, a wire harness can be hold | maintained reliably. Moreover, since the recessed part is formed in both the 1st protection member and the 2nd protection member, protection members can be connected in the state which attached the band to one protection member.

  In the harness protector, it is preferable that the plurality of blocks have the same shape.

  Thereby, since the harness protector of desired length can be implement | achieved by connecting an appropriate number of blocks, it can respond to various vehicle types.

  The harness protector is preferably housed in a bent state.

  Thereby, it can accommodate in a packing box with a compact packing form.

The perspective view which shows a mode that a cover is attached to a base. The side view of a harness protector. The perspective view which shows the harness protector in the state bent.

  Next, embodiments of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the harness protector 1 of the present embodiment is a member that protects the electric wires 6 constituting the wire harness 5. The wire harness 5 constitutes a high voltage circuit provided separately from a normal 12V system circuit. Specifically, the wire harness 5 connects a battery, an inverter, a motor, and the like of an electric vehicle or a hybrid vehicle. Moreover, the wire harness 5 is arrange | positioned under the floor (outer bottom face, the outer side of a vehicle body frame) of a vehicle body, and has a linear part. The harness protector 1 of the present embodiment is a member for protecting the linear portion of the wire harness 5.

  The harness protector 1 is made of resin and includes a plurality of blocks 2 connected to each other. Each block 2 has the same shape. Therefore, the number of blocks 2 can be varied according to the required length.

  The block 2 includes a base 10 and a cover 30. The cover 30 is a member disposed so as to face a predetermined surface of the vehicle body, and the base 10 is disposed so as to face the cover 30. Accordingly, the base 10 is exposed to the outside after the attachment to the vehicle body is completed. Hereinafter, the base 10 and the cover 30 will be described in detail. Hereinafter, in the description of the base 10 and the cover 30, the longitudinal direction of the wire harness 5 is referred to as “harness longitudinal direction”, and the direction in which the wire harness 5 is arranged is referred to as “harness arrangement direction” (see FIGS. 2 and 3). ).

  As shown in FIG. 2, the bases 10 are configured to be connectable. Each base 10 includes a bottom surface portion 11, a wall portion 12, a connection support portion 13, a connection convex portion (connection portion) 14, a rotation restriction portion 15, a vehicle body attachment portion 16, and an attachment receiving portion 17. , Is formed.

  The bottom surface portion 11 is a plate-like portion that is the lower side when attached to the vehicle body. The bottom surface portion 11 protects the wire harness 5 by receiving stones and the like bounced off the road on the outer surface. A plurality of wall portions 12 are formed on the inner side (upper side) of the bottom surface portion 11 so as to protrude further inward.

  The wall portion 12 is formed side by side in the harness arrangement direction. The longitudinal direction of the wall portion 12 coincides with the longitudinal direction of the harness, and the wall portion 12 functions as a partition that individually accommodates the electric wires 6 of the wire harness 5. At the upper end of the wall portion 12, a second concave portion 12a that is a portion recessed downward is formed. Each of the plurality of wall portions 12 is formed with two second recesses 12a. The 2nd recessed part 12a of the some wall part 12 is formed so that the position in a harness longitudinal direction may become the same. The second recess 12a is used for attaching a band 41 for holding the wire harness 5 to the base 10 as shown by a chain line in FIG.

  A pair of connection support portions 13 projecting on both sides in the harness arrangement direction are formed at one end portion (upper right end portion in FIG. 2) of the bottom surface portion 11 in the harness longitudinal direction. The pair of connection support portions 13 are respectively formed with connection long holes (connection portions) 13a. The longitudinal direction of the connection long hole 13a coincides with the harness longitudinal direction, and the depth direction of the connection long hole 13a coincides with the harness arrangement direction. On the other hand, a connecting convex portion 14 is formed at the other end portion of the bottom surface portion 11 in the harness longitudinal direction. The protruding direction of the connecting convex portion 14 coincides with the harness arrangement direction (that is, the rotation axis direction of the block 2 described later). The connection convex part 14 is formed in a pair so as to protrude on both sides in the harness arrangement direction.

  The pair of connecting protrusions 14 are configured to be insertable into a pair of connecting long holes 13 a of the other base 10. Specifically, by pressing the pair of connecting projections 14 so as to approach each other, the connecting projections 14 are elastically deformed. In this state, the connecting convex portion 14 and the connecting support portion 13 are aligned to release the pressing, whereby the connecting convex portion 14 can be inserted into the connecting long hole 13a. Accordingly, the bases 10 can be rotatably connected with the axis of the connecting convex portion 14 (that is, the rotation axis of the block 2) as the rotation center.

  Here, the wall portion 12 is not formed on the entire surface of the bottom surface portion 11, and is not formed in the vicinity of the connection support portion 13. A portion where the wall portion 12 is not formed is referred to as a rotation restricting portion 15. The rotation restricting portion 15 restricts rotation of the base 10 to the outside (rotation in a direction in which the outer surfaces of the base 10 are brought into contact with each other or rotation in a direction away from the vehicle body after being attached to the vehicle body).

  Specifically, as shown in FIG. 4, the rotation restricting portion 15 covers a part of the outer surface of the bottom surface portion 11 of the other base 10 on the end side in the harness longitudinal direction further than the connection long hole 13a. Placed in. With this configuration, when the base 10 is rotated outward, the bottom surface portion 11 contacts the rotation restricting portion 15 of the other base 10 (the rotation restricting portion 15 functions as a stopper). Thereby, the rotation to the outside is restricted among the rotations of the base 10.

  The vehicle body attachment portion 16 is formed on the outer surface of the wall portion 12 formed on the outermost side. The vehicle body attachment portion 16 protrudes upward, and a surface parallel to the bottom surface portion 11 is formed at the upper end portion. An insertion hole into which a bolt or the like can be inserted is formed on this surface. The base 10 (and thus the harness protector 1) can be attached to the vehicle body by aligning the insertion hole and the vehicle body side insertion hole and inserting and tightening a bolt. In the present embodiment, the vehicle body attachment portion 16 is formed only on one side in the harness arrangement direction, but may be formed on both sides.

  The attachment receiving portion 17 is configured to be engageable with an attachment hook 34 (described later) of the cover 30.

  As shown in FIG. 3, the cover 30 is formed with an attachment surface 31, a hinge 32, a boundary protection part 33, an attachment hook 34, a lock part 35, and a first recess 36.

  The attachment surface 31 is a portion that faces the vehicle body side when it is attached to the vehicle body (including a case where a gap is generated between the vehicle body and the vehicle body). A boundary protection part 33 is formed on one end of the attachment surface 31 in the harness longitudinal direction (the end on the side where the rotation restricting part 15 is formed) via a thin hinge 32.

  The boundary protection part 33 is a flat plate-like member and can freely rotate around the hinge 32. Moreover, the boundary protection part 33 is arrange | positioned so that the upper side of the attachment surface 31 of the other base 10 may be covered. Thereby, the clearance gap between the attachment surfaces 31 of the cover 30 which adjoins can be covered. Moreover, even if it is a case where it rotates so that the attachment surface 31 may become inside as shown to the dashed line of FIG. 4, the boundary protection part 33 will also rotate together by being pushed by another cover 30. FIG. Thereby, the boundary protection part 33 can protect the wire harness 5 not only when the harness protector 1 is arranged in a straight line but also when the harness protector 1 is bent.

  The attachment hook 34 is formed at a position corresponding to the attachment receiving portion 17 of the base 10 so as to protrude downward. By inserting the attachment hook 34 into the attachment receiving portion 17, the base 10 and the cover 30 are engaged by snap fit. In addition, the attachment method of the base 10 and the cover 30 is arbitrary, and the snap fit of another structure may be used, and the method of attaching with a volt | bolt etc. may be used.

  The lock portion 35 is an end portion in the harness longitudinal direction, and is formed in a pair at an end portion on the opposite side of the boundary protection portion 33 (in other words, the side on which the connecting convex portion 14 of the base 10 is formed). . When the cover 30 is attached to the base 10, the lock portion 35 is located further inside the connecting convex portion 14. Thereby, even if it is a case where a pair of connection convex part 14 is pressed inside, the elastic deformation of the connection convex part 14 is suppressed by interfering with the lock | rock part 35. FIG. Thereby, it can prevent that the connection of the connection convex part 14 and the connection long hole 13a remove | deviates easily.

  The first recess 36 is a recess formed in the vicinity of the attachment hook 34 and at a position corresponding to the second recess 12 a of the base 10. The first recess 36 is combined with the second recess 12a to form a hole, and the band 41 is disposed in the hole.

  Next, a method for assembling the harness protector 1 will be briefly described.

  Initially, the operator connects as many bases 10 as necessary. Next, the wire harness 5 is arranged on the connected base 10 (FIG. 2). Thereafter, the cover 30 is attached to the base 10 on which the wire harness 5 is disposed. Thereby, the wire harness 5 with the harness protector 1 is completed.

  The wire harness 5 with the harness protector 1 can be rotated to one side (the direction in which the mounting surface 31 rotates so as to be inside) by the mechanism described above (see FIG. 4), but to the other side. It cannot be rotated by the rotation restricting portion 15.

  Here, the wire harness 5 with the harness protector 1 is shipped to an automobile manufacturer or the like while being housed in a packing box or the like. When the wire harness is protected using a metal pipe as in the conventional case, the package shape becomes very large. In this respect, the harness protector 1 of the present embodiment is configured to be bent by rotating the base 10 to one side. Therefore, for example, as shown in FIG. 6, the harness protector 1 is bent so as to be swirled and accommodated in the packaging box 50, so that the package can be made very compact.

  Moreover, in the conventional protector which connects a some block so that rotation is possible, when bent, the clearance gap between blocks may become large and protection of a wire harness may become insufficient. In this respect, in the present embodiment, the gap generated inside the connection portion between the bases 10 is protected by the boundary protection portion 33, and the gap generated outside is protected by the rotation restricting portion 15.

  The shipped wire harness 5 with the harness protector 1 is attached to a predetermined portion under the floor of the vehicle body when the automobile is assembled. As described above, in the present embodiment, the harness protector 1 protects the wire harness 5 arranged in a straight line. Here, in the present specification, the phrase “the wire harness 5 is arranged in a straight line” includes not only a state in which the wire harness 5 is in an accurate straight line but also a state in which some bending occurs. . The slight bend is a bend that occurs when the wire harness 5 is attached or a bend that occurs according to the shape of the floor. Also, when the harness protector 1 is attached so that the rotation angle between adjacent blocks 2 is a predetermined angle or less (for example, 5 degrees or less, 10 degrees or less, 20 degrees or less), the wire harness 5 is “linearly”. It shall correspond to the “arranged” state.

  Here, in the case of a conventional protector that connects a plurality of blocks in a rotatable manner, when the wire harness is arranged in a straight line, the protector may be bent at the time of attachment or after attachment, and a load may be applied to the wire harness. . In this respect, in the harness protector 1 of the present embodiment, the bending in the direction in which the mounting surface 31 is inward (the direction in which the block 2 is brought closer to the vehicle body) is regulated by the vehicle body, and the bending on the opposite side is regulated by the rotation regulating unit 15. The Therefore, bending of the harness protector can be reliably prevented.

  As described above, the harness protector 1 of the present embodiment protects the portion of the wire harness 5 attached to the vehicle body that is linearly arranged and connects a plurality of blocks 2 that cover the periphery of the wire harness 5. It consists of The block 2 includes a connecting part (a connecting long hole 13a and a connecting convex part 14) and a rotation restricting part 15. A connection part connects the other block 2 rotatably. The rotation restricting portion 15 does not restrict rotation when rotating the other block 2 to one side in a state where the rotation restricting portion 15 is linearly connected to the other block 2, and rotates the other block 2 to the other side. In the case of causing the rotation, the rotation is restricted by contacting with the other block 2.

  Thereby, since the harness protector 1 can be bent by rotating the block 2 to one side, it can be accommodated compactly. Further, since the rotation of the other side of the block 2 is restricted, it is possible to prevent the harness protector 1 attached in a straight line from bending at least to the other side.

  Moreover, in the harness protector 1 of this embodiment, when rotating the other block 2 in the direction away from a vehicle body, rotation is controlled.

  Thereby, after the attachment to the vehicle body, the rotation of one side of the block 2 is regulated by the vehicle body, and the rotation of the other side of the block 2 is regulated by the rotation regulating unit. Bending can be prevented.

  Moreover, in the harness protector 1 of this embodiment, when the other block 2 is rotated to one side, the block 2 is pushed by the other block 2 so that the boundary with the other block 2 (details) Is provided with a boundary protection part 33 that rotates with the other block 2 while covering the inner part when rotating.

  Thereby, the wire harness 5 can be more reliably protected at the time of accommodation and attachment.

  Moreover, in the harness protector 1 of this embodiment, a connection part is the connection long hole 13a or the connection convex part 14 in which the longitudinal direction corresponds with the wire harness 5. FIG. The block 2 and the other block 2 are connected by the connection long hole 13a and the connection convex part 14 inserted in the connection long hole 13a.

  Thereby, since the block 2 can be moved along the longitudinal direction of the wire harness 5, it can be reliably and easily attached to the vehicle body while suppressing the dimensional accuracy of the harness protector 1.

  Moreover, in the harness protector 1 of this embodiment, the base 10 is provided with a connection part. The cover 30 includes a lock portion 35 that locks the base 10 and the other block 2 so as not to be disconnected.

  This makes it difficult for the blocks 2 to be disconnected from each other, so that resistance to external force can be improved.

  The preferred embodiment of the present invention has been described above, but the above configuration can be modified as follows, for example.

  The harness protector 1 of the above embodiment protects a high-voltage wire harness, but can also protect a normal voltage wire harness. Moreover, although the harness protector 1 of said embodiment is a structure which protects the wire harness 5 attached under the floor of a vehicle body, it can also protect the wire harness arrange | positioned other than under the floor (inside a vehicle etc.).

  In said embodiment, although the block 2 is comprised by connecting another member, the block 2 may be comprised from the single member.

  The configuration in which the rotation regulating unit 15 regulates the rotation and the configuration in which the boundary protection unit 33 protects the wire harness 5 are examples, and can be changed as appropriate.
