Description

[Technical Field]

[0001] The present invention relates to a cover that can be attached to a longitudinal end of an outer casing for electric wires that is attached to the outer periphery of electric wires to protect the electric wires of a wire harness or the like, an outer casing for electric wires, and a wire harness with an outer casing. [Background technology]

[0002] Conventionally, exterior bodies for wire harnesses have been used to attach and fix electric wires such as wire harnesses to a vehicle body, etc. Furthermore, by accommodating the wire harness in an accommodating portion of the exterior body, the exterior body exerts a function of regulating the path of the wire harness and a function of protecting the wire harness.

[0003] Furthermore, in recent years, in response to carbon dioxide emission regulations and the like, further improvements in fuel efficiency have been required for vehicles such as automobiles, and therefore there is a demand for weight reduction in parts mounted on vehicles such as automobiles. Accordingly, weight reduction is also required for wire sheathings attached to the outer peripheries of electric wires routed in vehicles such as automobiles, and therefore wire sheathings made of resin materials have been proposed.

[0004] As an electric wire sheathing made of a resin material, for example, there has been proposed an electric wire sheathing having a locking structure in which a locking portion formed in a plate-shaped portion is inserted into and locked into a locking hole portion formed in another plate-shaped portion, the locking portion being deformable into a first form that allows the locking portion to be inserted into the locking hole portion and a second form that is different from the first form, and in which an locking structure is formed in which the locking portion in the second form gets caught in the locking hole portion, thereby maintaining the protector in a shape that can accommodate the electric wire (Patent Document 1). In Patent Document 1, the deformable locking portion gets caught in the locking hole portion, thereby maintaining the protector in a shape that can accommodate the electric wire.

[0005] On the other hand, the wire sheathing, through which the wire harness is inserted and housed, is sometimes used in a state exposed to the external environment of the vehicle. In the protector of Patent Document 1, the end portion in the extension direction of the protector is open, so when used in a state exposed to the external environment of the vehicle, foreign objects such as stones may enter the inside of the protector from the end portion in the extension direction of the protector and damage the wire harness.

[0006] Therefore, in order to prevent stones and other foreign objects from entering the inside of the protector, the end portions of the protector in the extension direction have been covered with tape, etc. However, even if the end portions of the protector in the extension direction are covered with tape, it is difficult to wrap the tape evenly, and the workability of wrapping the tape is poor, so there are cases where it is not possible to sufficiently prevent stones and other foreign objects from entering.

[0007] In addition, in order to prevent foreign objects such as stones from entering the inside of the protector, a separate resin cover having a wire harness insertion portion with a notch in the radial direction of the wire harness has been attached to the end of the protector in the extension direction. However, in order to prevent foreign objects such as stones from entering the inside of the protector, the size of the wire harness insertion portion needs to correspond to the radial dimension of the wire harness. However, since the radial dimension of wire harnesses varies, it has been necessary to prepare covers having various wire harness insertion portion dimensions according to the radial dimension of the wire harness. Therefore, in order to attach the resin cover, it has been necessary to create a mold for each resin cover according to the various dimensions of the wire harness insertion portion.

[0011] According to an aspect of the cover of the electric wire outer casing of the present invention, the cover is provided with an electric wire insertion portion which is a cutout portion formed in the radial direction of the electric wire and into which the electric wire is inserted, and a slit formed in the radial direction of the electric wire for changing the radial dimension of the electric wire of the electric wire insertion portion or the position of the electric wire insertion portion. This makes it possible to change the dimension or position of the electric wire insertion portion in accordance with the radial dimension of the electric wire, and therefore prevents foreign matter from entering the inside of the electric wire outer casing even if the radial dimension of the electric wire changes.

[0012] According to the aspect of the cover of the electric wire sheathing of the present invention, the slit penetrating the resin sheet in the thickness direction extends from the electric wire insertion portion, so that the edge of the electric wire insertion portion can be folded along the slit, and therefore the size of the electric wire insertion portion can be easily changed according to the radial size of the electric wire. Therefore, even if the radial size of the electric wire changes, it is possible to more reliably prevent foreign matter from entering the inside of the electric wire sheathing.

[0013] According to an aspect of the cover for an electric wire sheathing of the present invention, the resin sheet has a plurality of slits formed therethrough along the wire insertion portion, which allows the size of the wire insertion portion to be changed with precision in accordance with the radial size of the electric wire, thereby more reliably preventing foreign matter from entering the inside of the electric wire sheathing even if the radial size of the electric wire changes.

[0014] According to an embodiment of the cover for an electric wire sheathing of the present invention, the slits that do not penetrate the resin sheet in the thickness direction but extend in the width direction are alternately provided on the first main surface and the second main surface along the length direction to form bellows-shaped slit portions, which allow the bellows-shaped slit portions to expand and contract in the length direction of the resin sheet, thereby making it possible to easily change the position of the electric wire insertion portion. Therefore, even if the radial dimension of the electric wire changes, it is possible to more reliably prevent foreign matter from entering the inside of the electric wire sheathing.

[0015] According to an aspect of the lid of the electric wire outer casing of the present invention, a wide portion is provided at the longitudinal end of the resin sheet facing the electric wire insertion portion for attaching the lid to the electric wire outer casing main body portion in which the electric wire is housed. This improves the stability of the lid's fixation to the electric wire outer casing main body portion, thereby preventing the lid from coming off the electric wire outer casing due to vehicle vibrations, etc.

[0016] According to an aspect of the lid of the electric wire sheathing of the present invention, a locking claw is provided at the end in the longitudinal direction facing the electric wire insertion portion, and a locking portion for locking the locking claw is provided between the bellows-shaped slit portion and the electric wire insertion portion in the longitudinal direction, so that the locking claw is locked in the locking portion, giving the lid a folded structure, thereby improving the mechanical strength of the lid. Furthermore, because the lid has a folded structure and is attached to the electric wire sheathing main body, the fixing stability of the lid to the electric wire sheathing main body is improved and the positioning of the lid to the electric wire sheathing main body is facilitated.

[0017] According to an aspect of the lid body of the wire outer casing of the present invention, the wire insertion portion further has an extension portion that can be extended in the extension direction of the wire to fix the wire to the lid body, thereby improving the fixing stability between the wire and the lid body.

[0018] According to an embodiment of the lid of the wire outer casing of the present invention, the resin sheet is a resin foam sheet, which facilitates changes in the radial dimension of the wire in the wire insertion portion and changes in the position of the wire insertion portion, and also prevents damage to the wire due to contact with the lid.

[0019] According to one aspect of the wire sheathing of the present invention, by comprising a wire sheathing main body that houses the wire, and the lid attached to the end of the wire sheathing main body in the extension direction of the wire, it is possible to obtain a wire sheathing that can prevent foreign matter from entering the wire sheathing main body.

DETAILED DESCRIPTION OF THE INVENTION

[0021] The following describes a lid (hereinafter, sometimes simply referred to as "lid") that can be attached to the longitudinal end of an electric wire outer casing that is attached to the outer periphery of the electric wire of the present invention. The lid of the present invention is formed from a resin sheet. The lid of the present invention also includes a wire insertion portion that is a cutout portion formed in the radial direction of the electric wire into which the electric wire is inserted, and a slit formed in the radial direction of the electric wire for changing the radial dimension of the electric wire of the electric wire insertion portion or the position of the electric wire insertion portion.

[0022] In the lid of the present invention, the radial dimension of the wire insertion portion can be changed by bending the resin sheet along the slit formed in the radial direction of the wire. Also, in the lid of the present invention, the position of the wire insertion portion can be changed by stretching the resin sheet in a direction perpendicular to the slit formed in the radial direction of the wire.

[0023] The cover of the present invention can change the size or position of the wire insertion portion according to the radial size of the wire, so that even if the radial size of the wire changes, foreign matter can be prevented from entering the inside of the wire outer casing.

[0024] Specific embodiments of the lid of the present invention will be described below with reference to the drawings. First, a lid according to a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a first aspect of the lid according to the first embodiment of the present invention, and is a perspective view illustrating a state in which the lid of the first aspect is attached to an end of an outer casing body for an electric wire in the extension direction of the electric wire. FIG. 2 is an explanatory view of the first aspect of the lid according to the first embodiment of the present invention. FIG. 3 is a second aspect of the lid according to the first embodiment of the present invention, and is a perspective view illustrating a state in which the lid of the second aspect is attached to an end of an outer casing body for an electric wire in the extension direction of the electric wire. FIG. 4 is an explanatory view of the second aspect of the lid according to the first embodiment of the present invention.

[0025] First, a first aspect of the lid according to the first embodiment of the present invention will be described. As shown in Figures 1 and 2, the lid 1 according to the first embodiment includes an electric wire insertion portion 10, which is a notch formed in the radial direction of the electric wire 200 and into which the electric wire 200 is inserted, and a slit 11 formed in the radial direction of the electric wire 200 for changing the dimension of the electric wire insertion portion 10 in the radial direction of the electric wire 200.

[0026] The wire insertion portion 10 is a cutout portion of the resin sheet that is recessed in the radial direction of the wire 200. The wire insertion portion 10 has a shape that corresponds to the shape of an outer surface 201 of the circumferential outer surface 202 of the wire 200 that faces the lid 1.

[0027] 1, an electric wire outer covering 100 attached to an outer surface 202 in the circumferential direction of an electric wire 200 includes an electric wire outer covering main body 101 that houses the electric wire 200, and a cover 1 attached to an end 102 of the electric wire outer covering main body 101 in the extension direction of the electric wire 200. The electric wire outer covering 100 is attached to a desired portion of the outer surface 202 in the circumferential direction of the electric wire 200 that should be protected from the external environment.

[0028] The wire sheathing main body 101 has a first side wall 103 along the extension direction of the wire 200, a second side wall 104 along the extension direction of the wire 200 facing the first side wall 103, and a bottom wall 105 connected to the first side wall 103 and the second side wall 104. The portion of the wire sheathing main body 101 facing the bottom wall 105 forms an opening, which makes it easy to attach the wire 200 to the wire sheathing main body 101 and to remove the wire 200 from the wire sheathing main body 101.

[0029] By attaching the lid 110 to the opening of the main body 101 of the outer casing for an electric wire, the outer casing 100 is attached to the outer surface 202 in the circumferential direction of the electric wire 200. As described above, the outer surface 202 in the circumferential direction of the electric wire 200 is protected from the external environment by the main body 101 of the outer casing for an electric wire and the lid 110.

[0030] As described above, in the outer packaging 100 for an electric wire, the lid 1 is attached to the end 102 of the outer packaging main body 101 in the extension direction of the electric wire 200. That is, the lid 1 is attached to the end in the longitudinal direction of the outer packaging 100 for an electric wire. The lid 1 is attached to the end 102 of the outer packaging main body 101 for an electric wire with its edge in contact with the first side wall 103, the second side wall 104, and the bottom wall 105 of the outer packaging main body 101, and the lid portion 110. The outer packaging 100 for an electric wire is provided with a fixing portion 106 for fixing the lid 1 to the end 102 of the outer packaging main body 101 for an electric wire, and the lid 1 is attached to the end 102 of the outer packaging main body 101 by fixing the lid 1 to the fixing portion 106.

[0031] In the wire outer casing 100, the fixing portion 106 is formed from a fixing portion 106-1 provided on the first side wall portion 103 and having a groove portion into which one edge of the cover body 1 is inserted, and a fixing portion 106-2 provided on the second side wall portion 104 and serving as a support base on which the other edge of the cover body 1 is placed.

[0032] The electric wire 200 is housed in the electric wire outer casing main body 101 while being inserted into the electric wire insertion portion 10 of the lid 1. When the electric wire 200 is housed in the electric wire outer casing main body 101 while being inserted into the electric wire insertion portion 10 of the lid 1, the electric wire outer casing 100 is attached to the outer surface 202 of the electric wire 200 in the circumferential direction.

[0033] 1 and 2, in the cover 1, a slit 11 penetrating through the resin sheet in the thickness direction extends from the electric wire insertion portion 10. Specifically, in the cover 1, the slit 11 extends from the electric wire insertion portion 10 in the radial direction of the electric wire 200.

[0034] Furthermore, in the cover 1, a plurality of slits 11 are provided along the wire insertion portion 10. Specifically, in the cover 1, a plurality of slits 11, 11, 11... are formed along the edge of the wire insertion portion 10. As described above, a plurality of slits 11, 11, 11... are formed along the outer surface 201 of the portion of the outer surface 202 in the circumferential direction of the wire 200 that faces the cover 1.

[0035] 1 and 2, in a first mode of the cover 1, the slits 11 are bent in response to the large radial dimension of the electric wire 200, i.e., the thickened electric wire 200. In the first mode, the slits 11 formed on the edge of the electric wire insertion portion 10 and extending in the radial direction of the electric wire 200 are bent in the elongation direction of the electric wire 200 from a point near the base of the slits 11, thereby widening the edge of the electric wire insertion portion 10. As described above, by bending the slits 11, the size of the electric wire insertion portion 10 corresponds to the radial dimension of the thickened electric wire 200.

[0036] In the first mode of the cover 1, the plurality of slits 11, 11, 11... formed along the edge of the electric wire insertion portion 10 are bent toward the main body 101 of the outer casing for electric wires.

[0037] Next, a second aspect of the lid 1 according to the first embodiment of the present invention will be described. As shown in Figures 3 and 4, in the second aspect of the lid 1, the radial dimension of the electric wire 200 is small, i.e., the slits 11 are not bent to accommodate the thinning of the electric wire 200. In the second aspect, the slits 11 formed at the edge of the electric wire insertion portion 10 and extending in the radial direction of the electric wire 200 are not bent in the elongation direction of the electric wire 200, so that the edge of the electric wire insertion portion 10 is not widened. As described above, since the slits 11 are not bent, the size of the electric wire insertion portion 10 corresponds to the radial dimension of the thinned electric wire 200.

[0038] As in the first and second aspects of the lid 1, the lid 1 can change the size of the wire insertion portion 10 in accordance with the size of the wire 200 in the radial direction.

[0039] An example of the resin sheet is a resin foam sheet. When the resin sheet is a resin foam sheet, bending of the slit 11 is facilitated, and the radial dimension of the electric wire 200 in the electric wire insertion portion 10 is easily changed. Furthermore, when the resin sheet is a resin foam sheet, damage to the electric wire 200 due to contact with the electric wire insertion portion 10 of the lid 1 can be prevented.

[0040] Furthermore, since the resin sheet is a resin foam sheet, the lid 1 having the wire insertion portion 10 and the slit 11 can be formed using, for example, a die with an embedded Thomson blade, which makes it easier to manufacture the lid 1.

[0041] In the lid 1, the dimensions of the wire insertion portion 10 can be changed in accordance with the radial dimension of the wire 200, so that even if the radial dimension of the wire 200 changes, foreign matter can be prevented from entering the inside of the wire sheathing 100. In particular, in the lid 1, the slit 11 penetrating the resin sheet in the thickness direction extends from the wire insertion portion 10, so that the edge of the wire insertion portion 10 can be folded along the slit 11, so that the dimension of the wire insertion portion 10 can be easily changed in accordance with the radial dimension of the wire 200. Therefore, in the lid 1, even if the radial dimension of the wire 200 changes, foreign matter can be more reliably prevented from entering the inside of the wire sheathing 100.

[0042] Furthermore, in the lid 1, a plurality of slits 11 penetrating the resin sheet in the thickness direction are provided along the electric wire insertion portion 10, so that the dimension of the electric wire insertion portion 10 can be changed with precision according to the radial dimension of the electric wire 200. Therefore, with the lid 1, even if the radial dimension of the electric wire 200 changes, it is possible to more reliably prevent foreign matter from entering the inside of the electric wire outer casing 100. Furthermore, by including an electric wire outer casing main body 101 that houses the electric wire 200, and the lid 1 attached to the end 102 of the electric wire outer casing main body 101 in the extension direction of the electric wire 200, it is possible to obtain an electric wire outer casing 100 that can prevent foreign matter from entering the inside of the electric wire outer casing main body 101.

[0043] Next, a lid according to a second embodiment of the present invention will be described with reference to the drawings. The lid according to the second embodiment shares major components with the lid according to the first embodiment, and the same components as those of the lid according to the first embodiment will be described using the same reference numerals. FIG. 5 is a perspective view showing a first main surface of a lid according to the second embodiment of the present invention. FIG. 6 is a perspective view showing a second main surface of a lid according to the second embodiment of the present invention. FIG. 7 is a perspective view illustrating a state before a lid according to the second embodiment of the present invention is attached to an end portion of an outer casing body for an electric wire in the extension direction of the electric wire. FIG. 8 is a perspective view illustrating a state after a lid according to the second embodiment of the present invention is attached to an end portion of an outer casing body for an electric wire in the extension direction of the electric wire. FIG. 9 is a perspective view illustrating a first aspect of a lid according to the second embodiment of the present invention attached to an end portion of an outer casing body for an electric wire in the extension direction of the electric wire. FIG. 10 is a perspective view illustrating a second aspect of a lid according to the second embodiment of the present invention attached to an end portion of an outer casing body for an electric wire in the extension direction of the electric wire.

[0044] 5 and 6, the lid 2 according to the second embodiment is formed from a resin sheet, for example, a resin foam sheet, and has a first main surface 21 and a second main surface 22 opposite to the first main surface 21. The lid 2 formed from the resin sheet has a width direction W and a length direction L.

[0045] The lid 2 has, at one end 23 in the length direction L, a wire insertion section 10 which is a cutout formed in the radial direction of the wire 200 and into which the wire 200 is inserted. The wire insertion section 10 is a cutout section of a resin sheet which is recessed in the radial direction of the wire 200. The wire insertion section 10 has a shape which corresponds to the shape of an outer surface 201 of a portion of an outer surface 202 in the circumferential direction of the wire 200 which faces the lid 2.

[0046] As shown in FIGS. 5 and 6 , the lid 2 has a slit 11 in the center in the longitudinal direction L that extends in the width direction W and does not penetrate the resin sheet in the thickness direction. In the lid 2, the slit 11 is formed in the radial direction of the electric wire 200 and, as will be described later, is a structure for changing the position of the electric wire insertion portion 10. The lid 2 has a plurality of slits 11. Specifically, the slits 11 are provided in parallel along the longitudinal direction L of the lid 2 and are alternately provided on the first main surface 21 and the second main surface 22 along the longitudinal direction L of the lid 2. The plurality of slits 11 are composed of a plurality of slits 11-1, 11-1, 11-1... provided in the first main surface 21 and a plurality of slits 11-2, 11-2, 11-2... provided in the second main surface 22. The slit 11-1 provided in the first main surface 21 does not reach the second main surface 22, and the slit 11-2 provided in the second main surface 22 does not reach the first main surface 21.

[0047] In the lid body 2, a bellows-shaped slit portion 25 is formed by a plurality of slits 11-1, 11-1, 11-1... provided on the first main surface 21 and a plurality of slits 11-2, 11-2, 11-2... provided on the second main surface 22.

[0048] As described above, the lid 2 has a bellows-shaped slit portion 25 in the center in the length direction L. The bellows-shaped slit portion 25 has a slit 11-1 that is provided in the first main surface 21 and does not reach the second main surface 22, and a slit 11-2 that is provided in the second main surface 22 and does not reach the first main surface 21, and therefore is a portion that can be stretched in the length direction L of the lid 2. Therefore, the center in the length direction L of the lid 2 is a portion that can be stretched in the length direction L of the lid 2.

[0049] The lid body 2 has a bellows-shaped slit portion 25 in the center of the length direction L, making the center portion in the length direction L an extensible portion, so that the position of the wire insertion portion 10, which is a cutout portion formed at one end 23 of the lid body 2 in the length direction L, can be changed.

[0050] The lid 2 has a wide portion 26 at the other end 24 in the length direction L facing the electric wire insertion portion 10, for attaching the lid 2 to the electric wire outer casing main body 101 in which the electric wire 200 is housed. The wide portion 26 is formed, for example, by making the other end 24 of the lid 2 wide so that it can be attached to the upper part of the electric wire outer casing main body 101. In other words, the wide portion 26 is an attachment portion for attaching the lid 2 to the electric wire outer casing main body 101. The wide portion 26 may be bent along the width direction W to attach the lid 2 to the upper part of the electric wire outer casing main body 101, or the lid 2 may be attached to the upper part of the electric wire outer casing main body 101 without being bent. Furthermore, by providing a non-penetrating slit at the base of one end 23 of the wide portion 26 provided at the other end 24, it becomes easier to fold the wide portion 26 along the width direction W and attach the lid body 2 to the top of the main body 101 of the outer casing for the electric wire.

[0051] Furthermore, the lid 2 has an extension portion 27 at the wire insertion portion 10 that can be stretched in the extension direction of the wire 200 and that fixes the wire 200 to the lid 2. A bending portion 28 is provided at the base of the extension portion 27, and by bending the base of the extension portion 27 at the bending portion 28, the extension portion 27 can be set to a state in which it is stretched in the extension direction of the wire 200.

[0052] Next, a mode of attaching the cover 2 to the main body 101 of the outer casing for electric wires in which the electric wires 200 are housed will be described.

[0053] As shown in Fig. 7 , first, a partial region of the electric wire 200 is housed in the electric wire sheathing main body 101. If necessary, an end 102 of the electric wire 200 in the extension direction of the electric wire 200 in the electric wire sheathing main body 101 is provided with a piece-like protruding portion 107 that protrudes from the bottom wall portion 105 in the extension direction of the electric wire 200. The electric wire 200 is placed on the protruding portion 107, and the electric wire 200 can be fixed to the electric wire sheathing main body 101 by fixing the protruding portion 107 and the electric wire 200 with a tape member 210.

[0054] 8 , with the electric wire 200 inserted into the electric wire insertion portion 10 of the lid 2, the lid 2 is attached to the end portion 102 of the electric wire outer casing main body 101 in the extension direction of the electric wire 200. By appropriately adjusting the length of the bellows-like slit portion 25, which is a portion that can be extended in the length direction L of the lid 2, the lid 2 can be attached to the electric wire outer casing main body 101 with the electric wire 200 inserted into the electric wire insertion portion 10 of the lid 2.

[0055] The lid 2 is attached to the outer casing main body 101 at a wide portion 26 provided at the other end 24 in the length direction L facing the wire insertion portion 10.

[0056] Furthermore, the extending portion 27 of the lid 2, which is stretched in the extension direction of the electric wire 200, is fixed to the electric wire 200 and the protruding portion 107 of the electric wire outer casing main body 101 by the tape member 210. Therefore, the lid 2 is fixed to the electric wire 200 and the electric wire outer casing main body 101 at the extending portion 27.

[0057] Next, a first aspect of the lid 2 according to the second embodiment of the present invention will be described. As shown in Fig. 9, in the first aspect of the lid 2, the radial dimension of the electric wire 200 is large, i.e., the electric wire 200 is thickened. Therefore, the bellows-like slit portion 25 provided in the central portion of the length direction L of the lid 2 does not extend in the length direction L of the lid 2. In the first aspect of the lid 2, the bellows-like slit portion 25 does not extend in the length direction L of the lid 2, so that the position of the electric wire insertion portion 10 formed at one end 23 of the lid 2 in the length direction L can be changed toward the other end 24. As described above, since the bellows-like slit portion 25 does not extend in the length direction L of the lid 2, the electric wire insertion portion 10 is changed to a position corresponding to the radial dimension of the thickened electric wire 200.

[0058] By attaching the lid 110 to the opening of the main body 101 of the outer casing for an electric wire, the outer casing 100 is attached to the outer surface 202 in the circumferential direction of the electric wire 200. As described above, the outer surface 202 in the circumferential direction of the electric wire 200 is protected from the external environment by the main body 101 of the outer casing for an electric wire and the lid 110.

[0059] As described above, in the electric wire outer covering 100, the lid 2 is attached to the end 102 of the electric wire outer covering main body 101 in the extension direction of the electric wire 200. The lid 2 is attached to the end 102 of the electric wire outer covering main body 101 with its edge in contact with the first side wall 103, the second side wall 104, and the bottom wall 105 of the electric wire outer covering main body 101, and the lid 110.

[0060] Next, a second aspect of the lid 2 according to the second embodiment of the present invention will be described. As shown in Fig. 10 , in the second aspect of the lid 2, the radial dimension of the electric wire 200 is small, i.e., the electric wire 200 is thinned. In response to this, the bellows-shaped slit portion 25 provided in the central portion of the length direction L of the lid 2 extends in the length direction L of the lid 2. In the second aspect, the bellows-shaped slit portion 25 extends in the length direction L of the lid 2 by opening the multiple slits 11, 11, 11... of the bellows-shaped slit portion 25. By extending the bellows-shaped slit portion 25 in the length direction L of the lid 2, the position of the electric wire insertion portion 10 formed at one end 23 of the lid 2 in the length direction L can be changed toward the bottom wall portion 105 of the wire outer casing main body 101. As described above, the accordion-shaped slit portion 25 is extended in the longitudinal direction L of the cover body 2, so that the wire insertion portion 10 is changed to a position corresponding to the radial dimension of the thinned wire 200.

[0061] As in the first and second aspects of the lid body 2, the lid body 2 can change the position of the wire insertion portion 10 in the length direction L of the lid body 2 according to the radial dimension of the wire 200.

[0062] In the lid 2, slits 11 extending in the width direction W and not penetrating the resin sheet in the thickness direction are alternately provided on the first main surface 21 and the second main surface 22 along the length direction L to form bellows-like slit portions 25. This makes the bellows-like slit portions 25 expandable in the length direction L of the lid 2, allowing the position of the wire insertion portion 10 to be easily changed. Therefore, even if the radial dimension of the electric wire 200 changes, foreign matter can be more reliably prevented from entering the inside of the electric wire outer casing 100. Furthermore, by including an electric wire outer casing main body 101 that houses the electric wire 200 and the lid 2 attached to the end 102 of the electric wire outer casing main body 101 in the extension direction of the electric wire 200, it is possible to obtain an electric wire outer casing 100 that can prevent foreign matter from entering the inside of the electric wire outer casing main body 101.

[0063] The lid body 2 has a wide portion 26 at the other end 24 of the length direction L of the lid body 2 facing the electric wire insertion portion 10 for attaching the lid body 2 to the electric wire outer casing main body 101 in which the electric wire 200 is housed. This improves the fixing stability of the lid body 2 to the electric wire outer casing main body 101, and prevents the lid body 2 from coming off the electric wire outer casing 100 due to vehicle vibrations, etc.

[0064] The lid body 2 further has an extension portion 27 in the wire insertion portion 10 that extends in the extension direction of the wire 200 and is used to fix the wire 200 to the lid body 2, thereby improving the fixing stability between the wire 200 and the lid body 2.

[0065] Next, a lid according to a third embodiment of the present invention will be described with reference to the drawings. The lid according to the third embodiment shares major components with the lids according to the first and second embodiments, and the same components as those of the lids according to the first and second embodiments will be described using the same reference numerals.

FIG. 17 is a perspective view showing a second aspect of the lid according to the third embodiment of the present invention, illustrating a state in which an electric wire is attached to an electric wire outer casing equipped with a lid according to the third embodiment of the present invention.

[0066] 11 and 12, the lid 3 according to the third embodiment is formed from a resin sheet, for example, a resin foam sheet, and has a first main surface 31 and a second main surface 32 opposite to the first main surface 31. The lid 3 formed from the resin sheet has a width direction W and a length direction L.

[0067] The cover 3 has, at one end 33 in the length direction L, a wire insertion section 10 which is a cutout formed in the radial direction of the wire 200 and into which the wire 200 is inserted. The wire insertion section 10 is a cutout section of a resin sheet which is recessed in the radial direction of the wire 200. The wire insertion section 10 has a shape which corresponds to the shape of an outer surface 201 of a portion of an outer surface 202 in the circumferential direction of the wire 200 which faces the cover 3.

[0068] 11 and 12 , the lid 3 has a slit 11 extending in the width direction W, not penetrating the resin sheet in the thickness direction, between one end 33 and the other end 34 in the length direction L. In the lid 3, similar to the lid 2, the slit 11 is formed in the radial direction of the electric wire 200, and as will be described later, is a structure for changing the position of the electric wire insertion portion 10. In the lid 3, similar to the lid 2, a plurality of slits 11, 11, 11... are provided. Specifically, a plurality of the slits 11 are provided in parallel along the length direction L of the lid 3, and are provided alternately on the first main surface 31 and the second main surface 32 along the length direction L of the lid 3. The multiple slits 11, 11, 11... are made up of multiple slits 11-1, 11-1, 11-1... provided in the first main surface 31 and multiple slits 11-2, 11-2, 11-2... provided in the second main surface 32. Slit 11-1 provided in the first main surface 31 does not reach the second main surface 32, and slit 11-2 provided in the second main surface 32 does not reach the first main surface 31.

[0069] In the lid body 3, similar to the lid body 2, a bellows-shaped slit portion 25 is formed by a plurality of slits 11-1, 11-1, 11-1... provided on the first main surface 31 and a plurality of slits 11-2, 11-2, 11-2... provided on the second main surface 32.

[0070] In the lid body 3, the accordion-shaped slit portion 25 has a first accordion-shaped slit portion 25-1 formed from near one end 33 of the lid body 3 in the longitudinal direction L to the center in the longitudinal direction L, and a second accordion-shaped slit portion 25-2 formed at a predetermined distance from the first accordion-shaped slit portion 25-1 to the center in the longitudinal direction L of the lid body 3 from near the other end 34.

[0071] As described above, the lid 3 has a bellows-like slit portion 25 consisting of a first bellows-like slit portion 25-1 and a second bellows-like slit portion 25-2 between one end 33 and the other end 34 in the longitudinal direction L. The bellows-like slit portion 25 has a slit 11-1 provided in the first main surface 31 and not reaching the second main surface 32, and a slit 11-2 provided in the second main surface 32 and not reaching the first main surface 31, and is therefore a region that can be stretched in the longitudinal direction L of the lid 3. Therefore, the region between the one end 33 and the other end 34 in the longitudinal direction L of the lid 3 is a region that can be stretched in the longitudinal direction L of the lid 3.

[0072] The cover body 3 has a bellows-shaped slit portion 25 between one end 33 and the other end 34 in the longitudinal direction L, which makes the area between the one end 33 and the other end 34 in the longitudinal direction L an extensible portion, so that the position of the wire insertion portion 10, which is a cutout portion formed at one end 23 of the cover body 3 in the longitudinal direction L, can be changed.

[0073] The cover 3 is provided with a locking claw 36 at the other end 34 in the longitudinal direction L facing the electric wire insertion portion 10. The cover 3 is also provided with a locking portion 37, to which the locking claw 36 is locked, between the first bellows-shaped slit portion 25-1 and the electric wire insertion portion 10 in the longitudinal direction L. By folding the cover 3 back between the first bellows-shaped slit portion 25-1 and the second bellows-shaped slit portion 25-2, the locking claw 36 is locked to the locking portion 37. The locking portion 37 can be, for example, a hole into which the locking claw 36 can be fitted.

[0074] It is not necessary to provide a predetermined gap between the first bellows-shaped slit portion 25-1 and the second bellows-shaped slit portion 25-2. In other words, the first bellows-shaped slit portion 25-1 and the second bellows-shaped slit portion 25-2 may be provided continuously.

[0075] Similarly to the lid body 2, the lid body 3 has an extension portion 27 at the wire insertion portion 10 that can be stretched in the extension direction of the wire 200 and that fixes the wire 200 to the lid body 2. A bending portion 28 is provided at the base of the extension portion 27, and by bending the base of the extension portion 27 at the bending portion 28, the extension portion 27 can be set to a state in which it is stretched in the extension direction of the wire 200.

[0076] Next, a mode of attaching the cover 3 to the main body 101 of the outer casing for electric wires in which the electric wires 200 are housed will be described.

[0077] As shown in FIG. 13, an end 102 of an outer sheathing body 101 in the extension direction of an electric wire 200 is provided with a piece-like protruding portion 107 that protrudes from a bottom wall portion 105 in the extension direction of the electric wire 200.

[0078] Furthermore, at the end 102 of the electric wire outer casing main body 101 in the extension direction of the electric wire 200, a plate-shaped support 108 for attaching the lid 3 extends from the first side wall 103, and a plate-shaped support 109 for attaching the lid 3 extends from the second side wall 104. The support 108 is provided in a substantially vertical direction with respect to the first side wall 103. The support 109 is provided in a substantially vertical direction with respect to the second side wall 104. The support 108 is disposed opposite the support 109 with a predetermined gap therebetween.

[0079] 14, by folding back the lid 3 between the first bellows-shaped slit portion 25-1 and the second bellows-shaped slit portion 25-2, the lid 3 can be attached to the supports 108 and 109 of the electric wire sheathing main body 101. That is, by sandwiching the supports 108 and 109 of the electric wire sheathing main body 101 between the first bellows-shaped slit portion 25-1 and the second bellows-shaped slit portion 25-2, the lid 3 can be attached to the end portion 102 of the electric wire 200 of the electric wire sheathing main body 101 in the extension direction.

[0080] The locking claws 36 are inserted into the locking portions 37 and locked to the locking portions 37, thereby improving the fixation of the lid body 3 to the supports 108 and 109. Note that the locking claws 36 may be welded to the locking portions 37 in a state where they are inserted into the locking portions 37, so that the locking claws 36 are locked to the locking portions 37.

[0081] Next, a first aspect of the lid 3 according to the third embodiment of the present invention will be described. As shown in Figures 15 and 16, the lid 3 is attached to the end 102 of the outer casing body 101 in the extension direction of the electric wire 200, with the electric wire 200 inserted into the electric wire insertion portion 10 of the lid 3. The electric wire 200 is placed on the protruding portion 107, and the electric wire 200 can be fixed to the outer casing body 101 by fixing the protruding portion 107 and the electric wire 200 with a tape member 210. The extending portion 27 of the lid 3, which is extended in the extension direction of the electric wire 200, is fixed to the electric wire 200 and the protruding portion 107 of the outer casing body 101 with the tape member 210. Therefore, the lid 3 is fixed to the electric wire 200 and the outer casing body 101 at the extending portion 27.

[0082] 15 and 16 , in the first state of the lid body 3, the radial dimension of the electric wire 200 is large, i.e., the electric wire 200 is thickened. Therefore, the first bellows-like slit portion 25-1 formed from the vicinity of one end 33 in the length direction L of the lid body 3 to the center in the length direction L does not extend in the length direction L of the lid body 3. In the first state of the lid body 3, the first bellows-like slit portion 25-1 does not extend in the length direction L of the lid body 3, so that the position of the electric wire insertion portion 10 formed at the one end 33 in the length direction L of the lid body 3 can be changed toward the lid portion 110 of the wire outer casing 100. As described above, the first bellows-like slit portion 25-1 does not extend in the length direction L of the lid body 3, so that the electric wire insertion portion 10 is changed to a position corresponding to the radial dimension of the thickened electric wire 200.

[0083] In the first state of the lid body 3, the first accordion-shaped slit portion 25-1 does not extend in the longitudinal direction L of the lid body 3, and accordingly, the second accordion-shaped slit portion 25-2 formed from the center of the lid body 3 in the longitudinal direction L to near the other end 34 does not extend in the longitudinal direction L of the lid body 3.

[0084] Next, a second aspect of the lid 3 according to the third embodiment of the present invention will be described. As shown in Fig. 17 , in the second aspect of the lid 3, the radial dimension of the electric wire 200 is small, i.e., the electric wire 200 is thinned. Accordingly, the first bellows-shaped slit portion 25-1 formed from near one end 33 of the lid 3 in the length direction L to the center of the lid 3 in the length direction L extends in the length direction L of the lid 3. In the second aspect, the first bellows-shaped slit portion 25-1 extends in the length direction L of the lid 3 by opening the multiple slits 11, 11, 11... of the first bellows-shaped slit portion 25-1. By extending the first bellows-shaped slit portion 25-1 in the length direction L of the lid 3, the position of the electric wire insertion portion 10 formed at one end 33 of the lid 3 in the length direction L can be changed toward the bottom wall portion 105 of the wire outer casing main body 101. As described above, since the first accordion-shaped slit portion 25-1 is extended in the longitudinal direction L of the cover body 3, the wire insertion portion 10 is changed to a position corresponding to the radial dimension of the thinned wire 200.

[0085] In the second state of the lid body 3, the first accordion-shaped slit portion 25-1 extends in the longitudinal direction L of the lid body 3, and accordingly, the second accordion-shaped slit portion 25-2 formed from the center of the lid body 3 in the longitudinal direction L to near the other end 34 extends in the longitudinal direction L of the lid body 3.

[0086] As in the first and second aspects of the lid body 3, the lid body 3 can change the position of the wire insertion portion 10 in the length direction L of the lid body 3 according to the radial dimension of the wire 200.

[0087] In the cover 3, the slits 11 extending in the width direction W and not penetrating the resin sheet in the thickness direction are alternately provided on the first main surface 31 and the second main surface 32 along the length direction L to form the bellows-like slit portions 25, which makes the bellows-like slit portions 25 expandable in the length direction L of the cover 3, thereby easily changing the position of the wire insertion portion 10. Therefore, even if the radial dimension of the wire 200 changes, it is possible to more reliably prevent foreign matter from entering the inside of the wire outer casing 100.

[0088] In addition, the cover body 3 has a locking claw 36 at the other end 34 in the longitudinal direction L facing the wire insertion section 10, and a locking section 37 for locking the locking claw 36 is provided between the first accordion-shaped slit section 25-1 and the wire insertion section 10 in the longitudinal direction L. Therefore, when the locking claw 36 is locked to the locking section 37, the cover body 3 has a folded structure, and the mechanical strength of the cover body 3 is improved.

[0089] Furthermore, the lid body 3 has a folded structure and is attached to the main body 101 of the outer casing for the electric wire, which improves the stability of the fixation of the lid body 3 to the main body 101 of the outer casing for the electric wire and also makes it easier to position the lid body 3 relative to the main body 101 of the outer casing for the electric wire.

[0090] An example of the electric wire 200 is a wire harness. As described above, by attaching the electric wire outer casing 100 to the circumferential outer surface 202 of the electric wire 200, it is possible to obtain a wire harness with an outer casing, which includes the wire harness and the electric wire outer casing 100, and in which the electric wire outer casing 100 is attached to the outer periphery of the wire harness.
