Description

[Technical field]

[0001] The present invention relates to a wire case to be attached to electric wires of, for example, a wire harness, and a covered electric wire. [Background technology]

[0002] For example, many wire harnesses and electric wires are arranged in a vehicle, and their ends are connected to electrical devices or have connectors at their ends. Some of these wire harnesses and electric wires extend from above to below. In addition, water may adhere to the surfaces of the wire harnesses and electric wires, for example, due to condensation. When a wire harness or an electric wire with water on its surface extends from above to below as described above, there is a risk that the water will run along the surface and enter the electrical devices or connectors connected to the ends.

[0003] To address such concerns, Patent Document 1 discloses a drainage protector for a wire harness that can drain water adhering to the wire harness in a short time by air supplied from an air supply port.

[0004] The drainage protector described in Patent Document 1 is configured such that the protector body is attached to a bent portion of a wire harness, the end of which is connected to an electrical device, bent into a U-shape so that the end is below the bent portion, and air is supplied from an opening provided in the protector body to quickly drain water that has adhered to the bent portion.

[0005] However, the drainage protector described in Patent Document 1 requires that the wire harness, whose end is connected to the electrical device, be bent into a U-shape extending downward from the end to form a bent section. In other words, there is a problem in that the wiring path becomes extra long to accommodate the wire harness. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Publication No. 11-136831 Summary of the Invention [Problem to be solved by the invention]

[0007] An object of the present invention is to provide an electric wire case and a covered electric wire that can remove water adhering to an electric wire without installing an extra path. [Means for solving the problem]

[0008] The present invention provides a case body for arranging a part of an electric wire extending from above to below inside the case, The case body has openings at both ends, through which the electric wires are inserted, and one of the openings at both ends is an introduction portion for introducing the electric wire from the outside of the case into the inside of the case; death , The opening at the other end of the openings provided at both ends is A lead-out portion for leading out the electric wire from inside the case to outside the case year, A wire bending section is provided for bending the wire disposed inside the case so as to face upward when the case body is attached to the wire, and a water drain hole is provided at a position that is lower in the case body when the case body is attached to the wire, and that communicates from the inside of the case to the outside of the case. The case body is a box-like body having a main surface and a plurality of side surfaces. , The wire bending section is composed of a partition plate that divides a part of the inside of the box. It is characterized by being an electric wire case.

[0009] The electric wire may be composed of only a conductor, or may be a covered electric wire in which the conductor is covered with an insulating coating. The electric wire may be a single wire or may be a plurality of wires. When the electric wire is a plurality of wires, the wires may be integrated as a pair of electric wires, the plurality of wires may be independent, or a wire harness in which the plurality of independent wires are bundled together. The drainage hole may be used to drain not only water but also various other liquids. The drainage hole may be one or more. The entire set of holes may be referred to as the drainage hole.

[0010] The bending of the wires at the wire bending portion can be in various forms, such as an obtuse or acute angle L-shape, L-shape, U-shape, V-shape, or arc shape, as long as the wires placed inside the case are bent upward in the installed state.

[0011] According to the present invention, water adhering to the electric wire can be removed without laying out any extra paths. In more detail, the electric wire is introduced into the case from the introduction portion, and the electric wire is led out of the case from the lead-out portion, and the electric wire case is attached to the electric wire, so that the electric wire arranged inside the case can be bent upward at the electric wire bending portion. Therefore, water attached to the electric wire upstream of the electric wire bending portion collects in the bent portion and drips or flows down into the case. Then, in the attached state, the dripped or flowed down water can be drained to the outside of the case from a water drain hole arranged at a lower position in the case body.

[0012] Therefore, in an electric wire extending from above to below, it is possible to prevent water from flowing over the surface of the electric wire downstream from the electric wire case in which a portion of the electric wire is disposed inside the case without having to route the electric wire, and to suppress water from entering the electric equipment or connector connected to the end.

[0013] The case body is box-shaped and has a main surface and a plurality of side surfaces adjacent to the main surface, so that a portion of the electric wires extending downward can be easily disposed inside the box-shaped case body.

[0014] The side surface may be provided on the entire periphery of the main surface, or a part of the periphery may be open. The portion facing the main surface via the side surface may have an opposing main surface or may be open. Even if the portion facing the main surface via the side surface is open, the portion may be configured to be openable and closable by a cover body formed integrally or separately.

[0015] The wire bending portion is formed of a partition plate that partitions a part of the inside of the box. With this, by arranging the electric wires along the partition plate inside the case, the electric wires can be bent so as to face upwards when the case is attached.

[0016] In addition, since the wires are arranged along the partition plate inside the case and the partition plate separates the wires bent upward from the other wires, it is possible to prevent the bent wires from coming into contact with the other wires inside the case, thereby preventing water from moving inadvertently.

[0017] As an aspect of the present invention, an electric wire fixing portion may be provided that fixes at least one of the electric wire introduced from the introduction portion and the electric wire led out from the lead-out portion outside the case. With this invention, even if, for example, vibration or external force acts on an electric wire case attached to an electric wire, the electric wire case can be fixed in a predetermined position without inadvertently moving in an electric wire extending from above to below, thereby preventing water from transmitting to the electric wire downstream.

[0018] As a further aspect of the present invention, the case body may have an opening, and a cover body may be provided that can be fixed to the case body so as to cover the opening. The cover body may be formed integrally with the case body or may be formed separately as long as it can close the opening of the case body. If the cover body is formed integrally with the case body, it may be formed so as to be openable and closable with respect to the case body by a hinge or the like.

[0019] According to this invention, a portion of the electric wire can be easily placed inside the case through the opening, and the cover body can maintain the bent state of the electric wire at the electric wire bending portion inside the case. In addition, since the opening can be covered with the cover body, water removed from the electric wires can be prevented from being unintentionally discharged from the opening and can be drained through the drainage hole.

[0020] In another aspect of the present invention, the case body may have a first insertion portion having the introduction portion at one end, a second insertion portion having the introduction portion at one end, and a corner portion connecting the other end of the first insertion portion and the other end of the second insertion portion in an intersecting direction, and the wire bending portion may be formed by the corner portion. The above-mentioned first and second insertion portions may be connected at an acute angle, a right angle, or an obtuse angle, and the intersection angle of the corner connecting the first and second insertion portions may be configured to be variable.

[0021] According to this invention, the electric wire is introduced from the introduction portion and passed through the first insertion portion, the direction of the electric wire is changed at a corner portion constituting the electric wire bending portion, the electric wire is passed through the second insertion portion, and the electric wire is led out from the lead-out portion, so that the electric wire case can be attached with a part of the electric wire disposed inside the case. Also, since the electric wire with the changed direction passes through the corner portion, the electric wire can be bent upward inside the case in the attached state.

[0022] As a further aspect of the present invention, a plurality of the partition plates may be provided so that the electric wires arranged inside the box are arranged in a substantially S-shape. According to this invention, the electric wire is arranged in a roughly S-shape by passing it through a path separated by a plurality of partition plates inside the case, and at least two bends can be formed in the electric wire, so that water that has reached the surface can be removed at the at least two bends, and water can be prevented from reaching the downstream side.

[0023] As a further aspect of the present invention, a pull-out prevention portion may be provided inside the box to prevent the electric wires arranged in the electric wire arrangement path formed by the partition plate from being pulled out. According to this invention, the state in which the electric wires are arranged relative to the partition plate functioning as the electric wire bending portion can be stably maintained.

[0024] In a further aspect of the present invention, a corner between the side walls in the vicinity of the bent portion where the electric wire is bent may be rounded. According to this invention, the corners of the portions where the electric wires are not arranged are rounded, so that the size of the case body can be reduced, and therefore space required for the wiring path can be saved.

[0025] As a further aspect of the present invention, a spiral arrangement guide portion that guides the electric wire so as to arrange it in a spiral shape may be provided inside the box, and the electric wire bending portion may be formed by the spiral arrangement guide portion. According to this invention, by arranging the electric wire so as to be guided by the spiral arrangement guide section which functions as the electric wire bending section, the electric wire is arranged in a spiral shape inside the case, and water running along the surface of the electric wire on the upstream side can be removed by the spiral section, preventing it from running to the electric wire on the downstream side.

[0026] As another aspect of the present invention, a mesh portion having a mesh shape may be formed on part or all of at least one of the multiple faces constituting the box shape, and the drainage holes may be formed by the mesh portion. According to this invention, the water removed from the bent portion can be drained more efficiently through the mesh portion than when it is drained through one small drainage hole.

[0027] As a further aspect of the present invention, a fixing portion for fixing the case body to an attachment location may be provided on an outer surface of the main surface. The fixing portion includes an anchor portion, a band portion, a clip provided on the case body, or a clip or a cable tie formed separately from the case body.

[0028] According to this invention, the wire case attached to a part of the wire extending downward can be fixed to the attachment location by the fixing part, and therefore the attached state can be stabilized even if vibration or the like acts on it.

[0029] In another aspect of the present invention, a U-shaped regulating section is provided that regulates the electric wire introduced from the introduction section and placed inside the case so that it is approximately U-shaped, the electric wire bending section is constituted by the U-shaped regulating section, and the outlet section is provided with a guide section that leads the electric wire regulated into the approximately U-shape to the outside of the box and guides the electric wire outside the box to a side opposite the introduction section.

[0030] According to this invention, the electric wire that has been restricted into an approximately U-shape by the U-shape restricting portion, which functions as the electric wire bending portion, can be led out to the outside of the box, and on the outside of the box, the electric wire can be guided by a guide portion to the side opposite the introduction portion. Furthermore, since the electric wires restricted by the U-shaped restricting portion are led out to the outside of the box, the electric wires arranged inside the case are short, and the case body can be configured compactly.

[0031] The present invention is also characterized in that it is a covered electric wire comprising an electric wire extending from above to below and the above-mentioned electric wire case, a portion of the electric wire being disposed inside the case of the case body, and the electric wire case being attached to the electric wire. According to the present invention, water adhering to the electric wire can be removed without laying out an extra path, and the water can be prevented from flowing to the electric wire on the downstream side.

[0032] In more detail, the electric wire is introduced into the case from the introduction portion, and the electric wire is led out of the case from the lead-out portion, and the electric wire case is attached to the electric wire, so that the electric wire arranged inside the case can be bent upward at the electric wire bending portion. Therefore, water that adheres to the electric wire upstream of the electric wire bending portion collects in the bent portion and drips inside the case. In the attached state, the dripping or flowing water can be drained to the outside of the case from a water drainage hole arranged at a lower position in the case body. Therefore, it is possible to prevent water from flowing to the electric wire downstream of the point where the electric wire case is attached.

[0033] In another embodiment of the present invention, the electric wire is a wire harness in which a plurality of electric wires are bundled together. , from the main line It may be a branch line. According to the present invention, it is possible to drain water that flows between the electric wires inside the cross section of the branch wire in which a plurality of electric wires are bundled, and therefore it is possible to prevent water from being transmitted to or from the trunk wire of the wire harness.

[0034] As a further aspect of the present invention, a connector may be provided at a lower end of the electric wire. According to this invention, it is possible to prevent water that has traveled along the surface of the electric wire from entering the inside of the connector. Effect of the Invention

[0035] According to the above configuration, it is possible to provide an electric wire case and a covered electric wire that can remove water adhering to the electric wire without installing an unnecessary path. [Brief description of the drawings]

[0037] (First embodiment) An embodiment of the present invention will now be described with reference to the drawings. FIG. 1 shows a perspective view of the wire case 1 in the mounting form of the first embodiment, FIG. 2 shows an explanatory diagram of the wire case 1 of the first embodiment, FIG. 3 shows an explanatory diagram in the form of a cross section of the wire case 1 of the first embodiment, and FIG. 4 shows an explanatory diagram for explaining mounting of the wire case 1 of the first embodiment.

[0038] In detail, FIG. 2(a) shows a front view of the electric wire case 1 in the installed state, and FIG. 2(b) shows a front view of the electric wire case 1 in the installed state with the inside shown by dashed lines. 3(a) shows a cross-sectional view of the electric wire case 1 taken along line AA in FIG. 2(a), and FIG. 3(b) shows a cross-sectional view of the electric wire case 1 taken along line AA with the cover 20 open.

[0039] FIG. 4(a) shows a front view of the wire case 1 before being attached to the wire harness 100, and FIG. 4(b) shows a front view of the wire case 1 after the wire harness 100 has been placed in the internal space 10X.

[0040] The wire case 1 is disposed in an internal space 10X as a portion of the wire harness 100 extending downward from above, and is attached to the wire harness 100 to form a cased wire harness 200, and drains water adhering to the surface of the wire harness 100 in the cased wire harness 200.

[0041] The wire harness 100, to which the electric wire case 1 is partially attached, is configured by bundling a plurality of covered electric wires. More specifically, the wire harness 100 is a branch line branched off from a trunk line (not shown), and is wired so as to extend from above (upper right side in FIG. 1) to below (lower left side in FIG. 1). The lower end of the wire harness 100 is provided with a connector 150.

[0042] The electric wire case 1 to be attached to a part of the wire harness 100 thus configured is composed of a case body 10 having a concave cross section, and a cover 20 that closes the opening of the case body 10 and is generally L-shaped when viewed from the front. The case body 10 is formed by a top surface 11, a side surface 12 on the rear side, and a bottom surface 13, and has a concave cross section with an open front side as shown in FIG. 3(b).

[0043] Further, the case body 10 has an upper side portion 14 above the bending point 16 and a lower side portion 15 below the bending point 16, and is configured to be substantially L-shaped when viewed from the front. The bottom surface 13 at the bending point 16 is formed with an open drain hole 17 .

[0044] Furthermore, an opening is provided at the upper end portion of the upper side portion 14 to form an inlet 18 for introducing the wire harness 100 from the outside, and an opening is provided at the lower end portion of the lower side portion 15 to form an outlet 19 for leading the wire harness 100 out to the outside.

[0045] In addition, in the upper portion 14 and the lower portion 15, the upper surface 11 is provided with a harness fixing portion 40 extending in a direction away from the folding point portion 16. The harness fixing portion 40 is for fixing the wire harness 100, a part of which is disposed in the internal space 10X of the wire case 1, to the wire case 1 by wrapping a tape or the like (not shown).

[0046] The cover 20, which covers the opening of the case body 10, which has a concave cross section and is open on the front side, is configured in a roughly L-shape when viewed from the front, with an upper portion 24 corresponding to the upper portion 14, a lower portion 25 corresponding to the lower portion 15, and a bend portion 26 corresponding to the bend portion 16.

[0047] The case body 10 and the cover 20 are pivotally connected between the bottom surface 13 of the upper portion 14 and the upper portion 24 of the cover 20 by a hinge portion 31. A plurality of hinge portions 31 are provided at predetermined intervals in the longitudinal direction of the upper portion 14.

[0048] The case body 10 and the cover 20 are provided with a fixing portion 32 that fixes the cover 20 to the case body 10 when the cover 20 covers the opening of the case body 10. A plurality of fixing portions 32 each composed of a locking frame 33 and a locking protrusion 34 (described later) are arranged at predetermined intervals.

[0049] Specifically, the fixing portion 32 is formed by an engaging frame 33 provided on the top surface 11 in the upper portion 14 and on the top surface 11 and bottom surface 13 in the lower portion 15, and an engaging protrusion 34 provided at corresponding locations in the upper portion 24 and lower portion 25 of the cover 20, and the engaging protrusion 34 can be engaged with the engaging frame 33 to fix the opening of the case body 10 in a state in which it is covered by the cover 20.

[0050] In addition, with the case body 10 and cover 20 configured as described above, when the opening on the front side of the case body 10 is covered with the cover 20, an internal space 10X that is surrounded by the case body 10 and the cover 20 and is approximately L-shaped when viewed from the front is formed.

[0051] To attach the wire case 1 consisting of the case body 10 and the cover 20 to the wire harness 100, as shown in FIG. 4(a), the wire case 1 with the cover 20 open relative to the case body 10 is placed on the wire harness 100 extending from above to below by pivoting the hinge portion 31.

[0052] Then, as shown in FIG. 4(b), a portion of the wire harness 100 is placed inside the case body 10 through the opening on the front side of the case body 10, and a tape (not shown) is wrapped around the harness fixing portion 40 and the wire harness 100 to fix the case body 10 and the wire harness 100.

[0053] In this state, in the internal space 10X, a bent portion 100X is formed in the wire harness 100 by bending the bend portion 16. Specifically, the upper surfaces 11 of the upper portion 14 and the lower portion 15 straddling the bend portion 16 form a substantially V-shape in a front view, and the wire harness 100 disposed in the internal space 10X along the upper surfaces 11 of the upper portion 14 and the lower portion 15 straddling the bend portion 16 forms the bent portion 100X bent upward. At this time, the water drainage hole 17 is disposed below the bent portion 100X.

[0054] Then, the cover 20 is pivoted by the hinge portion 31 to close the opening on the front side of the case body 10, the locking protrusion 34 is locked to the locked frame 33, and the case body 10 and the cover 20 are fixed by the fixing portion 32. In this way, the wire harness 100 is attached to the electric wire case 1 with a part of the wire harness 100 accommodated in the internal space 10X, thereby forming the case-equipped wire harness 200.

[0055] The wire case 1 attached to the wire harness 100 extending downward in this manner and the cased wire harness 200 including the wire case 1 are provided with the case body 10 that places a part of the wire harness 100 in the internal space 10X, and the case body 10 is provided with an inlet 18 for introducing the wire harness 100 from the outside of the case body 10 into the internal space 10X and an outlet 19 for leading the wire harness 100 from the internal space 10X to the outside of the case body 10. In addition, in the cased wire harness 200 in which the wire case 1 is attached to the wire harness 100, a bending point 16 for bending the wire harness 100 placed in the internal space 10X upward, and a water drainage hole 17 communicating from the internal space 10X to the outside of the case body 10 are provided at a position that is lower in the case body 10 in the attached state. Therefore, the cased wire harness 200 can remove water attached to the wire harness 100 without arranging an extra path.

[0056] More specifically, the wire harness 100 is introduced into the internal space 10X from the inlet 18, and the wire harness 100 is led out of the case body 10 from the outlet 19, and the electric wire case 1 is attached to the wire harness 100, so that the wire harness 100 arranged in the internal space 10X can be bent upward at the bend 16. Therefore, water attached to the wire harness 100 upstream of the bend 16 is collected at the bent portion 100X and drips or flows down into the internal space 10X. Then, the dripped or flowed down water can be drained to the outside of the case body 10 from the drain hole 17 arranged at a lower position in the case body 10 in the mounted state.

[0057] Therefore, in the case-equipped wire harness 200, without wrapping the wire harness 100 around, water can be prevented from flowing along the surface of the wire harness 100 downstream of the wire case 1 in which a portion of the wire harness 100 is disposed in the internal space 10X, and water can be prevented from entering the inside of the connector 150 connected to the lower end of the wire harness 100.

[0058] Further, a harness fixing portion 40 is provided for fixing the wire harness 100 introduced from the inlet 18 and the wire harness 100 led out from the outlet 19 outside the case main body 10, and fixes the wire harness 100. Therefore, even if the electric wire case 1 attached to the wire harness 100 is subjected to vibration or an external force, the electric wire case 1 in the case-equipped wire harness 200 is fixed in a predetermined position without being moved unintentionally, and water can be prevented from being transmitted to the wire harness 100 on the downstream side.

[0059] Moreover, the case body 10 has an opening, and is provided with a cover 20 that can be fixed to the case body 10 so as to close the opening. Therefore, a part of the wire harness 100 can be easily disposed from the opening into the internal space 10X, and the cover 20 can maintain the bent state of the wire harness 100 at the bending point 16 in the internal space 10X. In addition, since the opening can be covered with the cover 20, water removed from the wire harness 100 can be prevented from unintentionally discharging from the opening, and can be drained from the water drainage hole 17.

[0060] Moreover, the case body 10 has an upper portion 14 having an inlet 18 at its upper end, a lower portion 15 having an outlet 19 at its lower end, and a bend portion 16 that connects the lower end of the upper portion 14 and the upper end of the lower portion 15 in an intersecting direction. Therefore, the wire harness 100 is introduced from the inlet 18 and inserted through the upper portion 14, and then the direction of the wire harness 100 is changed at the bend portion 16 to pass through, and then the wire harness 100 is inserted through the lower portion 15 and led out from the outlet 19, whereby the wire case 1 can be attached with a portion of the wire harness 100 disposed in the internal space 10X.

[0061] In addition, since the wire harness 100 with its direction changed passes through the bending point 16, the wire harness 100 can be bent upward in the internal space 10X of the case-equipped wire harness 200.

[0062] In addition, since the wire harness 100 is a branch line branching off from the main line of the wire harness in which multiple insulated electric wires are bundled, water that flows between the insulated electric wires inside the cross section of the branch line of the wire harness 100 can be drained, and the transmission of water to or from the main line can be prevented.

[0063] In addition, the connector 150 is provided at the lower end of the wire harness 100, but since the wire case 1 is attached, water that has traveled along the surface of the wire harness 100 can be prevented from entering the inside of the connector 150. In addition, the electric wire case 1 may omit the cover 20 provided on the front side of the case body 10, and the front side of the case body 10 may be left open.

[0064] In the above-described wire case 1, the upper portion 14 and the upper portion 24 and the lower portion 15 and the lower portion 25 that straddle the bend point 16 and the bend point 26 have a fixed intersection angle that is generally L-shaped when viewed from the front. However, as long as the angle is such that the downstream side of the wire harness 100 where the bending portion 100X is bent by the bend point 16 faces upward, the bend point 16 and the bend point 26 may have an acute angle or an obtuse angle.

[0065] Furthermore, like wire case 1a shown in FIG. 5, which is a modified example of wire case 1, it may have a variable bending point portion 16a that can change the intersection angle between upper portion 14a / 24a and lower portion 15a / 25a. FIG. 5 is an explanatory diagram of a wire case 1a according to a modified example of the first embodiment.

[0066] Specifically, FIG. 5(a) shows a front view of the wire case 1a in a state where it is attached to the wire harness 100, and FIG. 5(b) shows a front view of the wire case 1a in a bent state. In the following description, the same components as those in the above-described electric wire case 1 are denoted by the same reference numerals, and the description thereof will be omitted.

[0067] The wire case 1a is configured such that upper portions 14a and 24a and lower portions 15a and 25a are separate bodies, and the angle is variable at a variable bending point 16a. The case body 10a constituting the wire case 1a differs from the case body 10 of the wire case 1, which is open on the front side, in that it is formed with a top surface 11 and front and rear side surfaces 12, with a cross-sectional concave shape that is open on the lower side, and the opening on the lower side of the case body 10a is configured to be closed with a cover 20a.

[0068] The variable bending points 16a are provided at the lower ends of the front and rear side surfaces 12 of the upper portion 14a and at the upper ends of the front and rear side surfaces 12 of the lower portion 25a, and are rotatably connected. A part of the wire harness 100 is accommodated in the bent portion 100X from below the case body 10a configured in this manner, and the opening is closed from below with the cover 20 to complete the assembly of the electric wire case 1a and to configure the case-included wire harness 200. At this time, as shown in Fig. 5(a), the wire harness 100 can be easily arranged in the internal space 10X by rotating at the variable bending point 16a so that the upper portion 14a and the lower portion 15a are substantially linear.

[0069] Then, as shown in FIG. 5(b), by rotating the lower portion 15a at the variable bend point 16a, the wire case 1a is bent at the variable bend point 16a, and the lower portion 15a faces upward while the upper portion 14a faces downward.

[0070] In this manner, in the internal space 10X of the wire case 1a where the upper portion 14a faces downward and the lower portion 15a faces upward, the bent portion 100X bends upward by the variable bending point 16a. Below the bent portion 100X at the variable bending point 16a, the end of the upper portion 24a and the end of the lower portion 25a are spaced apart from each other, forming a drainage hole 17.

[0071] The wire case 1a attached to the wire harness 100 extending downward in this manner can achieve the same effects as the wire case 1 described above. In addition, the wire case 1a may omit the cover 20a provided on the bottom side of the case body 10a, and the bottom side of the case body 10a may be left open.

[0072] Second embodiment In the above-described electric wire cases 1, 1a, the case main bodies 10, 10a are substantially L-shaped, but they may be configured in a box shape as shown in Figs. In the following description, the same components as those in the above-described electric wire cases 1 and 1a are denoted by the same reference numerals, and description thereof will be omitted.

[0073] FIG. 6 shows a front view of the wire case 1b in the mounted state of the second embodiment, and FIG. 7 shows a front view of the wire case 1b in the second embodiment with the cover 20b open. In addition, the internal structure is shown by a broken line in FIG. 6, and the wire harness 100 to be arranged is shown by a broken line in FIG.

[0074] The electric wire case 1b is composed of a box-shaped case body 10b with an open front side, and a cover 20b that closes the front opening of the case body 10b. The case body 10b is composed of a main surface 51 having a horizontally long rectangular shape when viewed from the front, and side walls 52, 53 formed along the periphery of the main surface 51, has an opening on the front side, and defines an internal space 10X therein.

[0075] The side walls 52 are configured as a pair along the width direction (left and right direction in Figure 7) on the periphery of the main surface 51, and the side walls 53 are configured as a pair along the vertical direction (top and bottom direction in Figure 7), and the opposing side walls 53 are provided with an inlet 18 and an outlet 19. Specifically, the inlet 18 is provided below the side wall 531 on one side (the side wall 53 on the right side in FIG. 6), and the outlet 19 is provided above the side wall 532 on the other side (the side wall 53 on the left side in FIG. 6).

[0076] A harness fixing portion 40 is provided by extending the side wall 52 adjacent to the inlet 18 and the outlet 19 . Furthermore, two partition plates 54 extending parallel to the side walls 52 are provided inside the box-shaped case body 10b.

[0077] Specifically, there is a partition plate 541 extending from the end of side wall 531 where inlet 18 is provided toward side wall 532, and a partition plate 542 extending from the end of side wall 532 where outlet 19 is provided toward side wall 531, and partition plate 54 (541, 542) is formed shorter than side wall 52.

[0078] Therefore, a wiring port 55 for wiring the wire harness 100 while bending it is formed between the tip of the partition plate 541 and the side wall 532, and between the tip of the partition plate 542 and the side wall 531. A scraper 56 that comes into close contact with the outer periphery of the wire harness 100 to be wired is provided in the wiring port 55.

[0079] The scraper 56 is divided so as to be in close contact with the outer periphery of the wire harness 100 to be routed from four directions, and is also provided at corresponding positions on a cover 20b to be described later. In addition, in the case-attached wire harness 200, the partition plate 541 located below the routing port 55 of the partition plate 542 and the side wall 522 located below the routing port 55 of the partition plate 541 are provided with water drainage holes 57.

[0080] The cover 20b is a rectangular plate corresponding to the main surface 51 constituting the case body 10b, and is pivotally connected by a hinge portion 31 provided on the side wall 521. The cover 20b can be fixed to the case body 10b in a state in which the opening on the open front side of the case body 10b is closed by a fixing portion 32 composed of an engaged frame 33 provided on the side wall 522 and an engaging protrusion 34 provided at a corresponding position on the cover 20b.

[0081] As described above, a scraper 56 is provided at a location on the cover 20b corresponding to the wiring port 55, which cooperates with the scraper 56 provided at the wiring port 55 to closely contact the outer peripheral surface of the wire harness 100 passing through the wiring port 55.

[0082] In the wire case 1b configured in this manner, the cover 20b is opened relative to the case body 10b, and the wire harness 100 is introduced into the internal space 10X from the inlet 18 and led out from the outlet 19 to the outside of the case body 10b. In detail, the wire harness 100 introduced into the internal space 10X from the inlet 18 passes between the side wall 522 and the partition plate 541 toward the side wall 532, and is bent back at the routing port 55 formed between the partition plate 541 and the side wall 532, forming the bent portion 100X.

[0083] The wire harness 100 bent back at the routing port 55 formed between the partition plate 541 and the side wall 532 passes between the partition plate 541 and the partition plate 542 toward the side wall 531, and is bent back at the routing port 55 formed between the partition plate 542 and the side wall 531 to form the bent portion 100X.

[0084] The wire harness 100 is bent back at the routing opening 55 formed between the partition plate 542 and the side wall 531, passes between the partition plate 542 and the side wall 521 toward the side wall 532, and is led out of the case body 10 through the lead-out opening 19.

[0085] In this state, the harness fixing portion 40 adjacent to the inlet 18 and the outlet 19 and the wire harness 100 are fixed by wrapping tape around them, and the cover 20b is pivoted at the hinge portion 31 to close the opening on the front side of the case main body 10b and fixed at the fixing portion 32, completing the attachment of the wire case 1b to the wire harness 100 and forming the cased wire harness 200.

[0086] The electric wire case 1b attached to the wire harness 100 extending downward in this manner is provided with a case body 10b that places a part of the wire harness 100 in the internal space 10X, and the case body 10b is provided with an inlet 18 that introduces the wire harness 100 from the outside of the case body 10 into the internal space 10X and an outlet 19 that leads the wire harness 100 from the internal space 10X to the outside of the case body 10b, and a wiring port 55 that bends the wire harness 100 placed in the internal space 10X upward in a case-attached wire harness 200 in which the electric wire case 1b is attached to the wire harness 100, and a water drain hole 57 that communicates from the internal space 10X to the outside of the case body 10b are provided at a position below the case body 10b in the case-attached wire harness 200. Therefore, the case-attached wire harness 200 can remove water attached to the wire harness 100 without wiring an extra path.

[0087] In detail, the wire harness 100 is introduced into the internal space 10X from the inlet 18, and the wire harness 100 is led out of the case body 10b from the outlet 19, and the electric wire case 1b is attached to the wire harness 100, so that the wire harness 100 arranged in the internal space 10X can be bent upward at the wiring port 55. Therefore, water attached to the wire harness 100 upstream of the wiring port 55 is collected at the bent portion 100X and drips or flows down into the internal space 10X. The dripped or flowed down water can be drained to the outside of the case body 10b from the water drainage hole 57 arranged at a position below the case body 10b in the case-equipped wire harness 200.

[0088] Therefore, in the case-equipped wire harness 200, without routing the wire harness 100, water can be prevented from flowing along the surface of the wire harness 100 downstream of the wire case 1b, in which a portion of the wire harness 100 is disposed in the internal space 10X, and water can be prevented from entering the inside of the connector 150 connected to the lower end of the wire harness 100.

[0089] Further, a harness fixing portion 40 is provided for fixing the wire harness 100 introduced from the inlet 18 and the wire harness 100 led out from the outlet 19 outside the case main body 10b, and fixes the wire harness 100. Therefore, even if vibration or an external force acts on the electric wire case 1b attached to the wire harness 100, the electric wire case 1b in the case-equipped wire harness 200 does not move unintentionally and is fixed in a predetermined position, thereby preventing water from being transmitted to the wire harness 100 on the downstream side.

[0090] Moreover, the case body 10b has an opening, and is provided with a cover 20b that can be fixed to the case body 10b so as to close the opening. Therefore, a part of the wire harness 100 can be easily disposed from the opening into the internal space 10X, and the cover 20b can maintain the wire harness 100 bent at the routing port 55 of the internal space 10X. In addition, since the opening can be covered with the cover 20b, water removed from the wire harness 100 can be prevented from unintentionally discharging from the opening, and can be drained from the water drainage hole 57.

[0091] Furthermore, since the case body 10c is box-shaped having a main surface 51 and multiple side walls 52, 53 facing the main surface 51, a portion of the wire harness 100 extending from above to below can be easily positioned inside the box-shaped case body 10c.

[0092] In addition, since a partition plate 54 is provided to separate a portion of the internal space 10X, by arranging the wire harness 100 along the partition plate 54 in the internal space 10X, the wire harness 100 can be bent upward in the case-equipped wire harness 200.

[0093] In addition, since the wire harness 100 bent upward is arranged along the partition plate 54 in the internal space 10X and is separated from the other wire harnesses 100 by the partition plate 54, it is possible to prevent the bent wire harness 100 and the other wire harnesses 100 from coming into contact with each other in the internal space 10X, thereby preventing water from moving inadvertently.

[0094] Further, a plurality of partition plates 54 are provided so that the wire harness 100 disposed in the internal space 10X is substantially S-shaped. Therefore, in the internal space 10X, by passing the wire harness 100 through a path partitioned by a plurality of partition plates 541, 542, the wire harness 100 is disposed substantially S-shaped, and at least two bent portions 100X can be formed in the wire harness 100. Therefore, water that travels to the surface can be removed by the at least two bent portions 100X, and water can be prevented from traveling to the downstream side.

[0095] Furthermore, as described above, the scraper 56 is provided at the corresponding location on the cover 20b. Therefore, when the opening on the front side of the case body 10b is blocked with the cover 20b, the scraper 56 provided at the routing port 55 and the scraper 56 provided on the cover 20b work together to adhere closely to the entire outer periphery of the bent portion 100X, thereby preventing water from flowing downstream. In addition, the wire case 1b may omit the cover 20b provided on the front side of the case body 10b, and the front side of the case body 10b may be left open.

[0096] Third embodiment Next, a wire case 1c according to a third embodiment will be described with reference to FIG. In the following description, the same components as those in the above-described electric wire cases 1 and 1b are denoted by the same reference numerals, and description thereof will be omitted.

[0097] FIG. 8 shows an explanatory diagram of a wire case 1c according to the third embodiment. FIG. 8(a) shows a front view of the wire case 1c of the third embodiment with the cover 20 seen through, and FIG. 8(b) shows a view seen in the direction of the arrow CC in FIG. 8(a).

[0098] In the above-described electric wire case 1b, the scraper 56 is provided at the wiring port 55, but in the electric wire case 1c, a retaining piece 561 is provided instead of the scraper 56. More specifically, a retaining piece 561 is provided at a position on the side wall 522 opposite to the tip of the partition plate 541 that forms the cable routing port 55 in the vertical direction.

[0099] A retaining piece 561 is provided at a location on the side wall 521 opposite to the tip of the partition plate 542 that forms the cable routing port 55 in the vertical direction. As shown in FIG. 8(b), the retaining piece 561 is composed of segments extending in opposing directions from the ends of the partition plate 541, the side wall 522, and the partition plate 542 and the side wall 521 away from the main surface 51.

[0100] In the wire case 1c configured in this manner, like the wire case 1b, the wire harness 100 is introduced into the internal space 10X from the inlet 18 and led out from the outlet 19 to the outside of the case body 10b. Specifically, the wire harness 100 introduced into the internal space 10X from the introduction port 18 passes between the side wall 522 and the partition plate 541 toward the side wall 532 and is disposed between the retaining pieces 561. Then, the wire harness 100 is bent back at the wiring port 55 formed between the partition plate 541 and the side wall 532 to form the bent portion 100X.

[0101] The wire harness 100 bent back at the routing port 55 formed between the partition plate 541 and the side wall 532 passes between the partition plate 541 and the partition plate 542 toward the side wall 531, and is bent back at the routing port 55 formed between the partition plate 542 and the side wall 531 to form the bent portion 100X.

[0102] The wire harness 100 is bent back at the routing opening 55 formed between the partition plate 542 and the side wall 531, wedges between the retaining pieces 561, passes between the partition plate 542 and the side wall 521 toward the side wall 532, passes through the outlet 19, and is led out of the internal space 10X.

[0103] In this state, the harness fixing portion 40 adjacent to the inlet 18 and the outlet 19 and the wire harness 100 are fixed by wrapping tape around them, completing the attachment of the electric wire case 1c to the wire harness 100 and forming the cased wire harness 200.

[0104] The wire case 1c of the third embodiment and the cased wire harness 200 including the wire case 1c can obtain the same effects as those obtained by the above-mentioned wire case 1b and the cased wire harness 200 including the wire case 1b.

[0105] Furthermore, a retaining piece 561 is provided to prevent the wire harness 100 arranged in the path partitioned by the partition plates 541, 542 in the internal space 10X from slipping out. Therefore, the state in which the wire harness 100 is arranged relative to the partition plates 541, 542 can be stably maintained. The wire case 1c may have a cover 20b on the front side of the case body 10c, or may be left open without the cover 20b.

[0106] (Fourth embodiment) Next, a wire case 1d according to a fourth embodiment will be described with reference to FIG. In the following description, the same components as those in the above-described electric wire cases 1, 1b, and 1c are denoted by the same reference numerals, and description thereof will be omitted.

[0107] FIG. 9 shows an explanatory diagram of a wire case 1d according to the fourth embodiment. Specifically, FIG. 9(a) shows a front view of a wire case 1d of the fourth embodiment with a cover 20 open, and FIG. 9(b) shows a bottom view of the wire case 1d.

[0108] Unlike the wire case 1c that includes partition plates 541 and 542, the wire case 1d shown in FIG. More specifically, a partition plate 541 extending from an end of the side wall 531 forming the inlet 18 toward the side wall 532 in parallel with the side wall 522 is provided in the internal space 10X.

[0109] The case body 10d has a main surface 51 extending from the inlet 18 and the outlet 19 along the harness fixing portion 40. In the electric wire case 1d having the case body 10d configured in this manner, the wire harness 100 introduced from the introduction port 18 into the internal space 10X is disposed between the partition plate 541 and the side wall 522 toward the side wall 532. The wire harness 100 is bent by the partition plate 541 to form a bent portion 100X, passes through the wiring port 55 formed between the tip of the partition plate 541 and the side wall 532, and is led out of the case body 10d from the lead-out port 19.

[0110] Then, the wire harness 100 is fixed to the harness fixing portion 40 near the inlet 18 and the harness fixing portion 40 near the outlet 19 by wrapping tape around it, and the opening on the front side of the case main body 10d is covered with the cover 20b and fixed with the fixing portion 32, thereby completing the attachment of the wire case 1d to the wire harness 100 and forming the case-equipped wire harness 200.

[0111] The wire case 1d of the fourth embodiment and the cased wire harness 200 including the wire case 1d can obtain the same effects as those obtained by the above-mentioned wire case 1b and the cased wire harness 200 including the wire case 1b.

[0112] In the above description, the wire case 1d is provided with only the partition plate 541, unlike the wire case 1d provided with the partition plates 541 and 542. However, instead of the partition plate 541, a structure may be provided with only the partition plate 542 extending from the side wall 532 constituting the outlet 19 toward the side wall 531 in parallel with the side wall 521. In this case as well, the path of the wire harness 100 arranged in the internal space 10X is arranged point-symmetrically, but the same effect as the wire case 1d described above can be achieved. Further, the electric wire case 1d is provided with the cover 20b, but the cover 20b may not be provided and the electric wire case 1d may be left open.

[0113] Fifth embodiment Next, a wire case 1e according to a fifth embodiment will be described with reference to FIG. In the following description, the same components as those in the above-described electric wire cases 1, 1b, 1c, and 1d are designated by the same reference numerals, and description thereof will be omitted.

[0114] FIG. 10 shows an explanatory diagram of a wire case 1e according to the fifth embodiment. Figure 10(a) shows a view seen from the arrow BB in Figure 10(b) described below, Figure 10(b) shows a bottom view of the wire case 1e, and Figure 10(c) shows a view seen from the arrow BB in Figure 10(b) when attached to the wire harness 100.

[0115] The above-mentioned wire cases 1b, 1c, and 1d are formed in a horizontally elongated rectangular shape when viewed from the front, but the wire case 1e is formed in a vertically elongated shape. The case body 10e constituting the wire case 1e is generally rectangular in shape and is elongated in the vertical direction, but is formed by a main surface 51e having one of two pairs of diagonal corners rounded in an arc shape, and side walls 52e, 53e provided on the peripheral portion thereof.

[0116] An inlet 18 is provided below one side wall 531 (the right side wall 53 in FIG. 10(a)), and an outlet 19 is provided above the other side wall 532 (the left side wall 53 in FIG. 10(a)).

[0117] In the side walls 52e, 53e, an arc-shaped side surface 58 is formed at one of two pairs of diagonal corners, and a water drainage hole 57 is provided in the arc-shaped side surface 58 that is downward when attached to the wire harness 100 (see Figure 10 (c)) of the pair of opposing arc-shaped side surfaces 58.

[0118] Furthermore, restricting columns 59 protruding from the main surface 51 are provided at positions facing the arcuate side surfaces 58 in the internal space 10X. Furthermore, an anchor 60 is provided on the outer surface side of the main surface 51, as shown in FIG. 10(b).

[0119] In the electric wire case 1e configured in this manner, the wire harness 100 is introduced from the inlet 18 into the internal space 10X and is led out from the outlet 19 to the outside of the case body 10e. In detail, the wire harness 100 introduced into the internal space 10X from the inlet 18 passes between the regulating cylinder 59 on the side closer to the inlet 18 and the arcuate side surface 58, and is bent back by the regulating cylinder 59 to form the bent portion 100X.

[0120] The wire harness 100 bent back at the regulating cylinder 59 on the side closer to the inlet 18 moves in the diagonal direction, passes between the regulating cylinder 59 on the side closer to the outlet 19 and the arc-shaped side surface 58, and is bent back at the regulating cylinder 59 to form a bent portion 100X.

[0121] The wire harness 100 bent back at the restricting cylinder 59 on the side closer to the outlet 19 passes between the partition plate 542 and the side wall 521 toward the side wall 532, passes through the outlet 19, and is led out of the internal space 10X. Then, anchors 60 provided on the outer surface of main surface 51 can be inserted into mounting holes (not shown) provided at a predetermined mounting location, and fixed to the predetermined mounting location.

[0122] The wire case 1e of the fifth embodiment and the cased wire harness 200 including the wire case 1e can obtain the same effects as those obtained by the above-mentioned wire cases 1b, 1c, 1d and the cased wire harness 200 including the wire cases 1b, 1c, 1d.

[0123] Furthermore, since the arc-shaped side surface 58 in the vicinity of the bent portion 100X where the wire harness 100 is bent has a rounded corner, the case body 10e can be made smaller in size, thereby making it possible to reduce the space required for the wiring path.

[0124] In addition, since the anchors 60 for fixing the case body 10e to the attachment location are provided on the outer surface of the main surface 51, the wire case 1e in the case-attached wire harness 200 can be fixed to the attachment location by the anchors 60. Therefore, the attachment state of the wire case 1e can be stabilized even if vibration or the like acts on it.

[0125] The wire case 1e may have a cover 20b on the front side of the case body 10e, or may be left open without the cover 20b. In addition, the anchor 60 to be inserted into the attachment location is provided on the case body 10, but a cable tie or clip may also be provided on the case body 10, or a fixing portion for fixing a separate clip or cable tie may be provided on the case body 10.

[0126] Sixth embodiment Next, a wire case 1f according to a sixth embodiment will be described with reference to Figs. In the following description, the same components as those of the above-mentioned wire cases 1, 1b, 1c, and 1d are designated by the same reference numerals and description thereof will be omitted.

[0127] FIG. 11 shows a front view of the wire case 1f of the sixth embodiment in an open state, and FIG. 12 shows an explanatory view of the wire case 1f of the sixth embodiment. Specifically, FIG. 11 shows a front view of the wire case 1f of the sixth embodiment with the cover 20b open.

[0128] Figure 12(a) shows a cross-sectional view taken along the line DD in Figure 11 with the cover 20 closed, Figure 12(b) shows a cross-sectional view taken along the line DD in Figure 12(a), and Figure 12(c) shows an enlarged rear view of the wire case 1f with the cover 20b of the sixth embodiment open.

[0129] The electric wire case 1f is composed of a case body 10f and a cover 20f pivotally connected to the case body 10f by a hinge portion 31. The case body 10f is substantially box-shaped and includes a main surface 51, a side wall 52, and only a side wall 532 of the side wall 53, and has drainage holes 57 at corners between the side walls 521 and 532 and at corners between the side walls 522 and 532. The main surface 51, the side walls 521 and 522, and the side wall 532 are chamfered at the locations of the drainage holes 57. The cover 20f is formed in the same shape as the case body 10f when viewed from the front.

[0130] Also, a U-shaped restraining box 543 is provided extending in the longitudinal direction from an end portion facing the side wall 532. The U-shaped restraining box 543 is disposed near the center between the side wall 521 and the side wall 522.

[0131] The U-shaped restricting box 543 is box-shaped with a short side length that is approximately 1 / 3 of the short side length of the side wall 532 extending in the short side direction, a long side length that is approximately 2 / 3 of the long side length of the side wall 52 extending in the long side direction, and the same height as the side walls 52 and 532, and is open on the back side.

[0132] Since a U-shaped regulating box 543 that is open on the rear side is provided, the main surface 51 and the internal space 10X are formed into a horizontal, square U-shape in front view with the side opposite the longitudinal direction of the side wall 532 being open.

[0133] The side opposite to the longitudinal direction of the side wall 532 is open, and the vicinity of the side wall 522 of the internal space 10X formed in a horizontally facing rectangular U-shape is used as the inlet 18, and the vicinity of the side wall 521 is used as the outlet 19. The inlet 18 and the outlet 19 open in the longitudinal direction, but the outlet 19 is provided at a recessed position on the side of the longitudinal side wall 532 and is also open on the side facing the U-shaped regulating box 543.

[0134] The U-shaped regulating box 543 that opens to the rear side is provided with a slope 544 on the rear side, which extends along the longitudinal direction from an end portion facing the side wall 532 in the longitudinal direction toward the side wall 533. The slope 544 is formed so that the wire harness 100 led out from the lead-out port 19 runs along the back surface (rear surface) of the main surface 51 on the side wall 532 side. Moreover, a fixing portion 40f extending outward along the longitudinal direction is formed near the center of the side wall 532 extending in the lateral direction. The fixing portion 40f is formed flush with the rear surface of the main surface 51.

[0135] In the case body 10f configured in this manner, the wire harness 100 is introduced into the internal space 10X from the introduction port 18. The wire harness 100 introduced into the internal space 10X passes between the U-shaped restraining box 543 and the side wall 522, and is bent back by the U-shaped restraining box 543 to form a bent portion 100X. The wire harness 100 bent back in the U-shaped regulating box 543 is disposed between the side wall 521 and the U-shaped regulating box 543 toward the outlet 19, and is led out of the internal space 10X through the outlet 19.

[0136] The wire harness 100 led out from the lead-out port 19 is bent toward the rear side of the U-shaped regulating box 543, and a bent portion 100X is formed. The wire harness 100 bent toward the rear side of the U-shaped regulating box 543 is arranged along the inclined path 544 provided on the rear side of the U-shaped regulating box 543 and in the longitudinal direction, and extends outward from the side of the side wall 532 along the rear side of the case main body 10f in the longitudinal direction.

[0137] Then, the wire harness 100 extending outward and the fixing portion 40f are fixed by wrapping tape around them, and the cover 20f is pivoted by the hinge portion 31 to close the opening on the front side of the case body 10f and fixed by the fixing portion 32, thereby completing the attachment of the wire case 1f to the wire harness 100 and forming the case-equipped wire harness 200.

[0138] The wire case 1f of the sixth embodiment and the cased wire harness 200 including the wire case 1f can obtain the same effects as those obtained by the above-mentioned wire cases 1b, 1c, d and the cased wire harness 200 including the wire cases 1b, 1c, d.

[0139] Furthermore, a U-shaped regulating box 543 is provided which regulates the wire harness 100 introduced from the inlet 18 and placed in the internal space 10X so that it is approximately U-shaped, and the outlet 19 leads the wire harness 100 regulated in the approximately U-shape from the U-shaped regulating box 543 to the outside of the case body 10f, and a ramp 544 is provided which guides the wire harness 100 to the side opposite the inlet 18 outside the case body 10f. Therefore, the wire harness 100 regulated in the approximately U-shape by the U-shaped regulating box 543 which functions as the wiring outlet 55 is led out to the outside of the case body 10f, and the wire harness 100 can be guided by the ramp 544 outside the case body 10f to the side opposite the inlet 18.

[0140] Furthermore, since the wire harness 100 restricted by the U-shaped restricting box 543 is led out to the outside of the case body 10f, the wire harness 100 disposed in the internal space 10X becomes short, and the case body 10f can be configured compactly. Although the electric wire case 1f is provided with the cover 20b, the electric wire case 1f may be left open without providing the cover 20b.

[0141] Seventh embodiment Next, a wire case 1g according to a seventh embodiment will be described with reference to Figs. In the following description, the same components as those of the above-mentioned wire cases 1, 1, 1c, and 1d are given the same reference numerals and the description thereof will be omitted.

[0142] FIG. 13 shows a perspective view of the wire case 1g in the mounting form of the seventh embodiment, FIG. 14 shows an explanatory diagram for explaining the mounting of the wire case 1g of the seventh embodiment, and FIG. 15 shows a perspective view of the mounting of the wire case 1g of the seventh embodiment.

[0143] Specifically, FIG. 13 shows a perspective view from the bottom side of an electric wire case 1g in the mounting form of the seventh embodiment. FIG. 14(a) shows a perspective view from the bottom side of the wire case 1g of the seventh embodiment with the base box 10g open, and FIG. 14(b) shows a perspective view from the bottom side of the wire case 1g of the seventh embodiment with the wire harness 100 placed in the base box 10g. FIG. 15 shows a perspective view from the bottom side of the base box 10g in a state where the lattice cover 70 is attached to the base box 10g.

[0144] The wire case 1g is composed of a roughly box-shaped base box 10g that is open on one side (upper in Figure 13), a pivoting lid portion 80 provided on the opening side (upper in Figure 13) of the base box 10g, and a roughly box-shaped lattice cover 70 that is positioned on the opposite side (upper in Figure 13) of the pivoting lid portion 80 from the base box 10g and is open on the other side (lower in Figure 13).

[0145] As shown in FIG. 14, the base box 10g is formed in a generally box-like shape with one side (upper in FIG. 14) open, and includes a generally rectangular main surface 51, side walls 52 arranged on both sides of the generally rectangular main surface 51 in the short direction and extending in the longitudinal direction, and side walls 53 arranged on both sides of the generally rectangular main surface 51 in the long direction and extending in the short direction. Incidentally, an introduction port 18 is provided on one side in the short direction (the right rear side in FIG. 14) of the side wall 531 on one side in the longitudinal direction (the right front side in FIG. 14).

[0146] In the internal space 10X surrounded by the main surface 51, the side wall 52, and the side wall 53, cylindrical regulating cylinders 59 are arranged at predetermined intervals on the other side in the longitudinal direction (the left rear side in FIG. 14). The regulating cylinders 59 are arranged at predetermined intervals along an imaginary arc.

[0147] The pivoting lid portion 80 is plate-shaped and covers the opening of the base box 10g, and has a first pivoting lid portion 81 provided on the other side in the longitudinal direction (the rear left side in Figure 14) and a second pivoting lid portion 82 provided on one side in the longitudinal direction (the front right side in Figure 14).

[0148] The first pivoting lid portion 81 is pivotally connected to the upper end portion of the side wall 532 on the other longitudinal side by a hinge (not shown). The second pivoting lid portion 82 is pivotally connected to the upper end portion of the side wall 521 on one side in the short direction (the far right side in FIG. 14) by a hinge (not shown).

[0149] The first pivoting lid part 81 and the second pivoting lid part 82 are approximately rectangular plate-shaped having a length equal to the short side length of the main surface 51, which is formed in an approximately rectangular shape, and a length slightly shorter than half the longitudinal length of the main surface 51.

[0150] Therefore, when the first pivoting lid portion 81 and the second pivoting lid portion 82 are pivoted to cover the opening of the base box 10g, a wiring opening 55f through which the wire harness 100 can pass is formed near the center in the longitudinal direction, as shown in Figure 15.

[0151] Furthermore, a restricting column 59 is provided on the surface of the first pivoting lid part 81 and the second pivoting lid part 82 opposite to the base box 10g. In detail, the second pivoting lid portion 82 is arranged at a predetermined distance from the regulating cylinder 59 provided in the internal space 10X along a virtual arc that is symmetrical about the center in the longitudinal direction, and the first pivoting lid portion 81 is provided with a regulating cylinder 59 at a position where its position in the lateral direction coincides with that of the regulating cylinder 59 provided on the second pivoting lid portion 82 on one side in the lateral direction.

[0152] The lattice cover 70 is composed of a rectangular main surface 71 that coincides with the base box 10g, and side walls 72, 73 formed along the periphery of the main surface 71, and is formed in a roughly box-like shape with the other side (downward in Figure 13) open.

[0153] The main surface 71 is provided with a plurality of mesh holes 77 that communicate from one side to the other side. More specifically, the drainage holes 57 are arranged in parallel in the longitudinal and lateral directions of the main surface 71, that is, in a lattice pattern.

[0154] Further, a side wall 73 on the other side in the longitudinal direction of the lattice cover 70 (the left rear side in FIG. 15) is provided with an outlet port (not shown). In detail, an outlet portion is formed on the side wall 73 corresponding to an extension of the regulating cylinder 59 provided on the first pivoting lid portion 81 arranged in line with the regulating cylinder 59 provided on the second pivoting lid portion 82 in the longitudinal direction.

[0155] In the wire case 1g configured in this manner, as shown in FIG. 14(a), the wire harness 100 is introduced into the internal space 10X from the introduction port 18 of the base box 10g and arranged along the longitudinal direction. Then, the wire harness 100 is bent along a plurality of restricting cylinders 59 arranged on the other side in the longitudinal direction of the internal space 10X (the left rear side in FIG. 14(a)) to form the bent portion 100X. At this time, the bent portion 100X is bent in a spiral shape so as to gradually move away from the main surface 51.

[0156] The wire harness 100 bent back in a spiral shape along the plurality of restricting columns 59 is extended toward the opening side as shown in FIG. 14(b). Then, the first pivot lid portion 81 and the second pivot lid portion 82 are pivoted to cover the opening of the base box 10g. At this time, as shown in FIG. 15, the wire harness 100 is passed through the wiring opening 55f formed between the first pivot lid portion 81 and the second pivot lid portion 82.

[0157] The wire harness 100 that has passed through the wiring port 55f is bent along a restricting cylinder 59 provided on the surface of the second pivot lid portion 82 to form a bent portion 100X. The wire harness 100 bent back at the restricting cylinder 59 provided on the surface of the second pivot lid portion 82 is extended in the longitudinal direction along the restricting cylinder 59 provided on the first pivot lid portion 81 .

[0158] In this state, the lattice cover 70 is attached to the base box 10g so that the wire harness 100 passes through the outlet, completing the attachment of the electric wire case 1g to the wire harness 100, and forming the cased wire harness 200.

[0159] The wire case 1g attached to the wire harness 100 extending downward in this manner and the case-equipped wire harness 200 including the wire case 1g are provided with a base box 10g that places a part of the wire harness 100 in the internal space 10X, an inlet 18 is provided in the base box 10g for introducing the wire harness 100 from the outside of the base box 10g into the internal space 10X, and an outlet is provided in the lattice cover 70 for leading the wire harness 100 from the internal space 10X to the outside of the base box 10g. In the cased wire harness 200, a routing port 55f is provided which bends the wire harness 100 to be placed in the internal space 10X upward, and a mesh hole 77 which communicates from the internal space 10X to the outside of the base box 10g is provided at a position on the lower side of the base box 10g in the cased wire harness 200. By orienting the lattice cover 70 so that it faces downward, that is, so that the mesh holes 77 provided in the main surface 71 of the lattice cover 70 face downward, water adhering to the wire harness 100 can be removed without routing the cased wire harness 200 through an unnecessary path.

[0160] In detail, the wire harness 100 is introduced into the internal space 10X from the inlet 18, and the wire harness 100 is led out of the base box 10g from the outlet, and the electric wire case 1g is attached to the wire harness 100, so that the wire harness 100 arranged in the internal space 10X can be bent upward at the wiring port 55f. Therefore, water attached to the wire harness 100 upstream of the wiring port 55f is collected at the bent portion 100X and drips or flows down into the internal space 10X. The dripped or flowed down water can be drained to the outside of the base box 10g from the mesh hole 77 arranged in the case-equipped wire harness 200 at a position below the base box 10g.

[0161] Therefore, in the case-equipped wire harness 200, without routing the wire harness 100, water can be prevented from flowing along the surface of the wire harness 100 downstream of the wire case 1g in which a portion of the wire harness 100 is disposed in the internal space 10X, and water can be prevented from entering the inside of the connector 150 connected to the lower end of the wire harness 100.

[0162] In addition, since the base box 10g is box-shaped having a main surface 51 and multiple side walls 52, 53 facing the main surface 51, a portion of the wire harness 100 extending from above to below can be easily positioned inside the box-shaped base box 10g.

[0163] In addition, a regulating cylinder 59 is provided in the internal space 10X to guide the wire harness 100 in a spiral arrangement. By arranging the wire harness 100 so as to be guided by the regulating cylinder 59, the wire harness 100 is arranged in a spiral arrangement in the internal space 10X to form a bent portion 100X, and water traveling along the surface of the wire harness 100 on the upstream side can be removed by the spiral bent portion 100X, preventing water from traveling to the wire harness 100 on the downstream side.

[0164] In addition, since the main surface 71 of the lattice cover 70 is provided with a plurality of mesh holes 77 arranged in a lattice pattern, the water removed from the bent portion 100X can be drained more efficiently through the mesh holes 77 than when it is drained through a single small drainage hole.
