Description

Technical Field

[0001] The present invention relates to a long body storage box for storing a part of a long body such as a wire harness, and a fixing portion for band-fixing the long body in the long body storage box.

Background Art

[0002] A long body such as a wire harness arranged in a vehicle may have a part thereof stored in a long body storage box such as a protector or an electrical connection box. As such a long body storage box, for example, a protector that stores and protects a part of a wire harness, which is a long body, is disclosed in Patent Document 1.

[0003] The protector disclosed in Patent Document 1 includes a fixing portion having an insertion passage through which a band for fixing the wire harness is inserted at a lead-out port for leading out the wire harness stored therein. The fixing portion configured as described above is said to be able to band-fix the wire harness by winding the band inserted through the insertion passage around the fixing portion and the wire harness.

[0004] However, in the protector disclosed in Patent Document 1, the tip side of the band inserted through the insertion passage is narrow, and there may be a case where the tip portion of the band inserted through the insertion passage cannot be pulled upward. For this reason, there is a possibility that the operation of winding a long body such as the wire harness with the band inserted through the insertion passage may become complicated.

Summary of the Invention

Problems to be Solved by the Invention

[0006] The purpose of this invention is to provide a container and fixing mechanism for long objects that can be easily wrapped around a long object to secure it. [Means for solving the problem]

[0007] This invention provides a storage box body that forms a storage space for accommodating a portion of a long body routed to a vehicle, the storage box body is provided with a long body passage portion for passing the long body in the inward and outward directions, and a fixing portion for securing the long body with a band that is wrapped around the long body passing through the long body passage portion, the fixing portion has a placement portion for placing the long body, and an insertion passage for inserting the band that is wrapped around the long body placed on the placement portion and the placement portion, the side into which the band is inserted into the insertion passage is the insertion side, The side from which the band inserted through the insertion passage is inserted is designated as the insertion side, and the aforementioned storage portion has the insertion passage formed on the side opposite to the side on which the elongated body is placed relative to the aforementioned storage portion, and has an insertion surface on which the insertion side is closer to the elongated body than the insertion side, and a band guide surface for guiding the band into the insertion passage is provided on the opposite side of the insertion surface and on the insertion side of the aforementioned storage portion, and the insertion side of the band guide surface is closer to the elongated body than the insertion side, characterized in that it is an elongated body storage box.

[0008] Furthermore, this invention relates to a fixing part for fixing a long body to be routed on a vehicle with a band that is wrapped around the long body, comprising: a mounting part on which the long body is placed; and an insertion passage through which the band that is wrapped around the long body placed on the mounting part and the mounting part are inserted, wherein the side into which the band is inserted into the insertion passage is designated as the insertion side, and the side from which the band inserted into the insertion passage is removed is designated as the removal side, wherein the mounting part has the insertion passage formed on the side opposite to the long body side on which the long body is placed relative to the mounting part, and has an insertion surface on which the removal side is closer to the long body than the insertion side, wherein a band guide surface is provided on the opposite side of the insertion surface and on the insertion side of the mounting part for guiding the band into the insertion passage, and the removal side of the band guide surface is closer to the long body than the insertion side.

[0009] The aforementioned elongated object is composed of an elongated shape, with a portion of it being housed in the aforementioned elongated object housing box, and includes, for example, electric wires, wire harnesses made by bundling multiple electric wires, communication lines for communicating between electrical equipment, and bundles of electric wires or communication lines.

[0010] The aforementioned long-length housing box protects the long-length object and includes, for example, an electrical junction box that houses one end of the long-length object and connects electrical equipment, and a protector that prevents the long-length object routed in a vehicle from interfering with other components. The electrical junction box includes junction boxes, fuse boxes, relay boxes, etc., mounted in vehicles.

[0011] With this invention, a box for storing long objects having the above-described configuration allows for easy wrapping of a band around the long object to secure it. More specifically, the mounting section for supporting the elongated object has an insertion passage through which the band to be wrapped around the elongated object and the mounting section is inserted from the insertion side to the insertion side, and has an insertion surface where the insertion side is closer to the elongated object than the insertion side. Furthermore, on the opposite side of the insertion surface, and on the insertion side of the mounting section, there is a band guide surface where the insertion side is closer to the elongated object than the insertion side. For this reason, for example, after inserting the band from the insertion side of the insertion passage, the band can be brought into contact with the band guide surface, guiding the tip of the band inserted through the insertion passage towards the elongated object along the insertion surface. This allows the tip of the band inserted through the insertion passage to be guided towards the elongated object, and the tip of the band can be easily and reliably pulled out from the insertion passage towards the elongated object. Therefore, the elongated object and the mounting section can be easily wrapped with the band, improving the efficiency of the wrapping work in which the elongated object is secured with the band.

[0012] Furthermore, even if the band is inserted through the insertion passage after the long object has been placed on the mounting section, the tip of the band can be pulled out from the insertion side of the insertion passage toward the long object. Therefore, even after the long object has been routed, it can be secured with the band.

[0013] In one embodiment of this invention, the elongated body passage portion is provided so as to extend outward from the storage box body, and the fixing portion may be provided inside the storage box body at the position where the elongated body passage portion is provided.

[0014] According to this invention, since the fixing part is provided inside the storage box body, the fixing part that secures the long object with a band can be protected. Therefore, unintended interference with the fixing part from outside the storage box body can be prevented. Furthermore, since a fixing part is provided at the same location as the elongated body passage, it is possible to suppress the influence of the routing direction of elongated bodies routed outside the storage box body on elongated bodies routed inside the storage box body. Therefore, an elongated body storage box having the above configuration can route elongated bodies that are led out from the elongated body passage in a desired direction.

[0015] In another aspect of this invention, the insertion passage is provided with an opposing wall on the insertion side that faces the outlet for drawing out the band in the insertion passage, and the opposing wall contacts the band through which the insertion passage has been inserted, guiding the tip of the band toward the elongated body. The opposing wall includes walls such as side walls that constitute the main body of the storage box, and walls separately provided inside the main body of the storage box.

[0016] This invention makes it possible to guide the tip of the band towards the longer body more reliably and easily. More specifically, the band inserted through the insertion passage extends toward the longer body as it moves from the insertion side to the removal side. Therefore, by bringing the tip of the band into contact with the opposing wall, the tip of the band can be guided toward the longer body more reliably. Thus, the tip of the band can be guided toward the longer body more reliably and easily.

[0017] Furthermore, by providing an opposing wall on the insertion side of the outlet, the tip of the band can be pulled out towards the longer body even if the distance between the outlet and the opposing wall is narrow. In other words, since there is no need to secure space on the insertion side of the mounting section to pull out the tip of the band, the space on the insertion side of the opposing wall can be effectively utilized.

[0018] In another aspect of this invention, the opposing wall may be a side wall that forms the inner circumferential surface of the storage box body. This invention allows for a simpler structure to guide the end portion of the band more reliably and easily towards the longer object. Furthermore, because the end portion of the band can be pulled out towards the longer object, the fixing part can be positioned near the side wall. In other words, the storage space formed by the storage box body can be effectively utilized.

[0019] In another aspect of this invention, the insertion surface and the band guide surface may form an insertion opening into the insertion passage for inserting the band. This invention allows the tip of the band to be easily inserted into the insertion opening formed on the insertion side of the band guide surface. Therefore, the tip of the band can be easily and reliably pulled out from the insertion passage towards the long object, improving the work efficiency of wrapping the long object with the band.

[0020] Furthermore, in an embodiment of this invention, the mounting portion described above has a mounting surface on which the elongated body is placed, and the mounting surface described above may be formed in an arc shape that is recessed on the opposite side when viewed from the direction in which the elongated body fixed to the mounting surface is routed. This invention allows the band to be wrapped around the elongated body and the mounting part while the elongated body is aligned with the mounting surface, thereby enabling the elongated body to be firmly and stably fixed to the mounting part via the band.

[0021] In another aspect of this invention, the mounting surface described above may be formed between the quarter point on the opposite side of the mounted elongated body and the quarter point on the insertion side of the mounted elongated body, when viewed from the routing direction.

[0022] According to the present invention, it is possible to reduce the gap formed between the long body and the band wound around the placement part and the long body and the placement surface. Therefore, the long body can be firmly and stably fixed to the placement part via the band.

[0023] As an aspect of the present invention, the long body is a wire harness bundling a plurality of electric wires, the long body passing part is composed of an outer passing part protruding outside the housing box body and an inner passing part provided inside the housing box body, the long body passing part is provided with an arrangement surface for arranging a corrugated tube for covering the wire harness, the placement part is provided with a placement surface for placing the wire harness, and inside the housing box body, the arrangement surface and the placement surface may be flush.

[0024] According to the present invention, since the fixing part is provided at the position where the long body passing part is provided, and the arrangement surface for arranging the corrugated tube and the placement surface for placing the wire harness are flush, the wire harness can be arranged at the central part of the corrugated tube led out to the outside from the outer passing part through the long body passing part. Therefore, the long body housing box having the above-described configuration can route the wire harness in a desired direction outside the long body housing box.

[0025] As an aspect of the present invention, the opposing wall may be inclined so as to approach the end of the insertion side of the placement part as it faces the long body side. According to the present invention, by abutting the band against the standing part, the tip part of the band can be more reliably guided toward the long body side, so that the workability of the operation of winding the band around the long body and the placement part can be further improved.

Effects of the Invention

[0026] According to the present invention, it is possible to provide a long body housing box and a fixing part that can easily wind a band around a long body and fix the long body.

[Modes for carrying out the invention]

[0028] One embodiment of this invention will be described below with reference to Figures 1 to 6. Figure 1 shows a schematic perspective view of the electrical junction box 1 with harness as seen from the upper HU, right WR, and external LA, and Figure 2 shows a schematic exploded perspective view of the electrical junction box 1 with harness as seen from the lower HD, right WR, and internal LB. Figures 3 and 4 show explanatory diagrams of the fixing part 50 provided on the center case 31. Figures 5 and 6 show explanatory diagrams of the process of band-securing the harness 10 to the fixing part 50.

[0029] Figures 3 to 6 will be described in detail. Figure 3(a) shows a schematic plan view of the upper holding part 41 and the fixing part 50 as seen from the lower HD, Figure 3(b) shows a schematic rear view of the fixing part 50 as seen from the inner LB, and Figure 4 shows a cross-sectional view taken along arrow AA in Figure 3(a).

Figure 7(a) shows a schematic cross-sectional view of the fixing part 50 according to another embodiment, and Figure 7(b) shows a schematic cross-sectional view of the fixing part 50 according to another embodiment in which the tip portion of the band 61 is pulled out to the downward HD.

[0030] Figure 2 shows only the outer side LA and left side WL of the disassembled electrical junction box 1 with harness in order to clarify the structure of the fixing part 50 that secures the harness 10. Also, in Figures 3 to 7, the lower side HD is shown at the top in order to clarify the structure of the fixing part 50 that secures the harness 10. Figures 5 to 7 show cross-sectional views corresponding to the cross-section taken along arrow AA in Figure 3(a).

[0031] Here, in Figure 1, the vertical direction is defined as the height direction H, and the direction perpendicular to the height direction H and in which the harness 10 extends from the electrical connection box 30 is defined as the inward / outward direction L. The direction perpendicular to both the inward / outward direction L and the height direction H is defined as the insertion direction W. In Figure 1, the left side along the inward / outward direction L is defined as the outer side LA, and the right side as the inner side LB. Similarly, the downward side along the height direction H is defined as the lower side HD, the upward side as the upper side HU, the left side along the insertion direction W is defined as the left side WL, and the right side along the insertion direction W is defined as the right side WR. The above directions correspond to the same directions in Figures 2 to 7.

[0032] As shown in Figures 1 and 2, the electrical junction box 1 with a harness consists of a harness 10 routed through the vehicle and an electrical junction box 30 into which an exterior material 20 through which the harness 10 is inserted is attached. The electrical junction box 30 houses a portion of the harness 10 through which the exterior material 20 is inserted. One end of the harness 10 is connected to an electronic component mounted in the electrical junction box 30, and the other end of the harness 10 is connected to an electrical component mounted in the vehicle.

[0033] The harness 10 is a wire harness made by bundling together multiple insulated wires, each in which a conductor is surrounded by an insulating coating, and is routed along a predetermined routing path in a vehicle. In this embodiment, the harness 10 is made by bundling together multiple insulated wires, but it may also be made by bundling together a single insulated wire. It may also be made by bundling together one or more communication cables, or by bundling together insulated wires and communication cables.

[0034] The outer casing material 20 is a cylindrical resin corrugated tube through which the harness 10 is inserted. More specifically, the outer casing material 20 is composed of a bellows structure in which large-diameter sections, whose outer surface protrudes outward along its entire circumference, and small-diameter sections, whose outer surface is recessed inward along its entire circumference, are arranged alternately and continuously along its longitudinal direction.

[0035] The electrical junction box 30 is an enclosure that houses electronic components such as relays and fuses, as well as electrical circuits. More specifically, as shown in Figures 1 and 2, the electrical junction box 30 consists of a cylindrical center case 31 having openings on both sides in the height direction H, an upper cover 32 that closes the opening on the upper side HU of the center case 31, and a lower cover 33 that closes the opening on the lower side HD of the center case 31. The electrical junction box 30 is also provided with an exterior retaining part 40 that holds the exterior material 20.

[0036] The center case 31 is a frame that is roughly rectangular in plan view when viewed from the upper side HU, and forms a housing space for housing electronic components, electrical circuits, and part of the harness 10. The center case 31 configured in this way has upper holding parts 41 that constitute the exterior holding parts 40 near the corners of the lower side HD, the outer side LA, and the left side WL. In addition, a fixing part 50 is provided on the inside (internal side LB) of the upper holding parts 41 of the center case 31 for fixing the harness 10 inserted into the electrical connection box 30 via the exterior holding parts 40.

[0037] As shown in Figure 3(a), the upper holding portion 41 is composed of an upper penetrating portion 411 that penetrates the center case 31 in the inward-outward direction L, an outer mounting portion 412 that protrudes outward from the outer peripheral surface of the center case 31, and an inner mounting portion 413 that is inside the outer mounting portion 412 and is continuous with the outer mounting portion 412. The upper through-hole 411 forms a through-hole that penetrates the upper end of the center case 31 in a semicircular shape in the direction of the plate thickness. The inner diameter of the upper through-hole 411 is approximately the same as the outer diameter of the large-diameter portion of the exterior material 20.

[0038] The outer mounting portion 412 is a tubular body with a roughly U-shaped front view and an opening on the lower HD, protruding outwards LA from a position corresponding to the upper through portion 411. The outer mounting portion 412 also has an inner diameter that is approximately the same as the outer diameter of the large-diameter portion of the exterior material 20, and has a roughly semicircular outer inner circumferential surface 414 formed flush with the upper through portion 411 on the lower HD.

[0039] On the outer inner circumferential surface 414 of the outer mounting portion 412 that protrudes outward LA, three locking ribs 415 that protrude downward HD are provided at predetermined intervals in the inward-outward direction L. The locking rib 415 is a rib that protrudes downward from the outer inner circumferential surface 414 toward the HD when viewed from the front, and the tip portion of the locking rib 415 forms a semicircle with an inner diameter that is approximately equal to the outer diameter of the small diameter portion of the exterior material 20.

[0040] As shown in Figure 3(a), three locking ribs 415 having this shape are provided in a row in the inner-outer direction L at approximately the same interval as the distance between the large-diameter portions of the exterior material 20, in the central portion of the outer mounting portion 412 in the inner-outer direction L. More specifically, the locking ribs 415 on the outer side LA are provided at a predetermined distance from the outer side LA end of the outer mounting portion 412 to the inner side LB, and the locking ribs 415 on the inner side LB are provided at a predetermined distance from the upper through portion 411 to the outer side LA.

[0041] In this manner, the outer mounting portion 412 on which the locking ribs 415 are arranged allows the exterior material 20 to be attached by fitting the smaller diameter portion of the exterior material 20 into the locking ribs 415 and fitting the larger diameter portion of the exterior material 20 between the locking ribs 415.

[0042] The inner mounting portion 413 is a roughly rectangular, solid box extending from the inner circumferential surface of the center case 31 to the inner side LB, and is positioned opposite the outer mounting portion 412. Furthermore, as shown in Figures 3(a) and 3(b), the inner mounting portion 413 has an inner circumferential surface 416 formed flush with the outer inner circumferential surface 414 at the end of the lower side HD.

[0043] The inner mounting portion 413 will be described in detail. As shown in Figures 3(a) and 3(b), the inner mounting portion 413 extends from the center case 31 to the inner side LB so as to correspond to the central portion of the outer mounting portion 412 in the insertion direction W. The length of the inner mounting portion 413 in the insertion direction W is approximately half the length of the outer mounting portion 412 in the insertion direction W, and the length of the inner mounting portion 413 in the height direction H is approximately the same as the radius of the large diameter portion of the exterior material 20.

[0044] The inner inner surface 416, which is formed flush with the outer inner surface 414, has an arc shape when viewed from the rear, and has an inner diameter the same as the outer diameter of the large diameter portion of the exterior material 20, similar to the outer inner surface 414. More specifically, when viewed from the rear, both ends of the inner inner surface 416 in the insertion direction W correspond to positions of approximately 40 degrees to the right WR and left WL along the arc shape of the outer inner surface 414, with the apex of the upper HU on the outer inner surface 414 as the center. In other words, the length of the inner inner surface 416 in the insertion direction W is shorter than that of the outer inner surface 414.

[0045] As described above, the center case 31 has a fixing part 50 for securing the harness 10 with a band, which is provided on the inner side LB of the inner mounting part 413. As shown in Figures 3 and 4, the fixing portion 50 is a hollow box with an opening on the upper side HU, protruding from the inner mounting portion 413 toward the inner side LB. The length of the fixing portion 50 in the insertion direction W and the height direction H is approximately the same as that of the inner mounting portion 413. The fixing portion 50 configured in this way has a mounting portion 51 on which the harness 10 is placed, a guide portion 52 provided on the right side WR of the mounting portion 51, and an outlet 53 that connects the inside of the fixing portion 50 with the left side WL.

[0046] As shown in Figures 3(b) and 4, the mounting portion 51 is a plate-like body that protrudes from the inner mounting portion 413 to the inner side LB such that its lower end surface (the end surface of the lower side HD) is flush with the inner circumferential surface 416. In other words, in a rear view, the mounting portion 51 is a curved, arc-shaped plate-like body with an inner diameter equal to the outer diameter of the large-diameter portion of the exterior material 20. Here, the lower end surface of the mounting portion 51 that is flush with the inner circumferential surface 416 is referred to as the mounting surface 511.

[0047] The mounting portion 51 will now be described in detail. As shown in Figures 3(b) and 4, in a rear view, the mounting portion 51 is formed such that, with the apex of the upper HU of the inner mounting portion 413 as the end of the right WR, it curves from the right WR toward the left WL and gradually moves toward the downward HD. The end of the left WL of the mounting portion 51 is approximately the same as the end of the left WL of the inner mounting portion 413.

[0048] In other words, the mounting surface 511, which is the upper end surface of the mounting portion 51, is an arc shape that is recessed into the upper HU when viewed from the rear side from the inner side LB, and is formed between the apex of the upper HU and the end of the left side WL on the outer inner circumferential surface 414. To put it another way, when the exterior material 20 is attached to the outer inner circumferential surface 414, the mounting surface 511 is formed to correspond to the quarter point of the upper HU and the quarter point of the left side WL of the exterior material 20.

[0049] Furthermore, the plate-shaped mounting section 51 has an insertion surface 512 on its upper side HU that is curved parallel to the mounting surface 511. That is, the insertion surface 512 has a left side WL that is lower HD than the right side WR (see Figure 4).

[0050] The guide portion 52 is a substantially flat plate that protrudes from the inner mounting portion 413 to the inner side LB by the same length as the mounting portion 51 on the right side WR of the mounting portion 51, and is inclined so as to gradually move downward towards the HD as it moves from the right side WR to the left side WL. That is, the guide portion 52 has a guide surface 521 that is inclined so as to gradually move downward towards the HD as it moves from the right side WR to the left side WL.

[0051] The left end of the guide surface 521 is positioned above the insertion surface 512 at a predetermined distance H in the height direction. In other words, the mounting portion 51 and the guide portion 52 are arranged at different heights H. The mounting portion 51 (insertion surface 512) and the guide portion 52 (guide surface 521) configured in this way have an insertion opening 54 that connects the inside of the fixing portion 50 to the right side WR. Furthermore, the end of the inner LB in the mounting section 51 and the end of the inner LB in the guide section 52 are connected by a wall that forms the fixing section 50.

[0052] As shown in Figure 4, the outlet 53 is an opening that connects the inside of the hollow-shaped fixing part 50 with the left side WL of the fixing part 50, and is formed by cutting out the end of the left side WL of the fixing part 50 and the central part in the inward-outward direction L of the mounting part 51 in the height direction H. That is, the fixing part 50 communicates in the insertion direction W via the outlet 53 and the insertion opening 54, and has an insertion passage 55 that curves along the insertion surface 512 from the right side WR towards the left side WL and gradually moves downward HD.

[0053] As described above, the fixing portion 50 configured in this way is positioned on the inner side LB of the upper holding portion 41. That is, the fixing portion 50 is provided near the corner of the lower side HD, the inner side LB, and the left side WL of the center case 31. Therefore, the side wall portion 311, which is the side wall of the left side WL of the center case 31, is positioned on the left side WL of the outlet 53.

[0054] The upper cover 32 is a cover body configured with a concave cross-section that closes the opening of the upper HU in the center case 31 and can be locked to the center case 31.

[0055] The lower cover 33 is a cover body configured with a concave cross-section that closes the opening of the lower HD in the center case 31, and can be locked and fixed to the center case 31. Furthermore, when the lower cover 33 and the center case 31 are locked and fixed together, the lower cover 33 is provided with a lower holding portion 42 that, together with the upper holding portion 41, constitutes the exterior holding portion 40, at a position opposite to the upper holding portion 41.

[0056] The lower holding portion 42 penetrates the lower cover 33 in the inward-outward direction L, and covers the opening of the outer mounting portion 412 while the center case 31 and the lower cover 33 are locked and fixed together (see Figures 1 and 2). More specifically, the lower holding portion 42, when the center case 31 and the lower cover 33 are locked together, forms a circular through-hole in the electrical connection box 30 that has the same diameter as the large-diameter portion of the exterior material 20, together with the upper through-port 411, and holds the exterior material 20 in cooperation with the outer mounting portion 412. The lower holding portion 42 has substantially the same configuration as the upper through-port 411 and the outer mounting portion 412, except that it is upside down.

[0057] As described above, the upper cover 32 and the lower cover 33 can be locked to the center case 31, thereby closing the openings provided on both sides of the center case 31 in the height direction H. Therefore, the fixing part 50 provided inside the electrical connection box 30 can be prevented from unintended external interference.

[0058] Next, a method for securing the harness 10 to the fixing part 50 using the fixing band 60 will be explained with reference to Figures 5 and 6. Here, the fixing band 60 is a so-called cable tie, comprising a flexible, strip-shaped band 61 and a buckle 62 to which the base end of the band 61 is connected, and which allows the tip portion of the band 61 to be inserted and secured (see Figure 5(a)).

[0059] First, with the center case 31 inverted in the height direction H, the end of the inner side LB of the exterior material 20 through which the harness 10 is inserted is placed in the inner mounting portion 413, and the exterior material 20 is placed in the outer mounting portion 412. At this time, the small diameter portion of the exterior material 20 is fitted into the locking rib 415, and the large diameter portion of the exterior material 20 is fitted between the locking ribs 415, thereby allowing the exterior material 20 to be attached to the upper holding portion 41. Then, with the exterior material 20 attached, the harness 10 through which the exterior material 20 is inserted is placed on the mounting surface 511 (see Figure 5(a)).

[0060] Next, insert the tip of band 61 into the insertion port 54 from the right side WR towards the left side WL, so that the tip is positioned on the left side WL. At this time, the tip of band 61 is facing upward HU (see Figure 5(a)).

[0061] In this manner, with the tip of the band 61 facing upward HU, the band 61 is pressed against the guide surface 521. Here, the guide surface 521 is inclined so that it gradually moves upward HU as it moves from the right side WR to the left side WL. Therefore, by bringing the band 61 into contact with the guide surface 521, the tip of the band 61 can be flipped up downward HD. As a result, the tip of the band 61 is guided along the guide surface 521 to the insertion opening 54 while facing upward HU as it moves from the right side WR to the left side WL (see Figure 5(b)).

[0062] In this state, the tip of the band 61 is pressed against the guide surface 521, and the tip of the band 61 is inserted through the insertion passage 55 from the right side WR to the left side WL. At this time, the insertion surface 512 that forms the insertion passage 55 is formed to curve as it moves from the right side WR to the left side WL and gradually toward the downward HD, so that the tip of the band 61 guided by the insertion surface 512 can be guided toward the left side WL and the downward HD (see Figure 5(b)).

[0063] As the insertion passage 55 is guided to the left WL and the lower HD in this manner, the tip of the band 61 inserted from the insertion opening 54 into the left WL comes into contact with the side wall 311 located on the left WL of the insertion opening 54. Here, since the tip of the band 61 is facing the left WL and the lower HD, the tip of the band 61 that comes into contact with the side wall 311 is guided to the lower HD and led out to the lower HD of the center case 31 (see Figure 6(a)). In other words, the operator can easily pull the tip of the band 61 to the lower HD and reliably and easily insert the band 61 into the buckle 62.

[0064] By inserting the band 61, which has been pulled out to the lower HD, through the buckle 62 and pulling it out to the lower HD, the fixing band 60 can be wrapped around the harness 10 and the mounting part 51, thereby band-fixing the harness 10 to the mounting part 51 (see Figure 6(b)). Here, with the harness 10 band-fixed to the fixing part 50, the mounting surface 511 is formed between the quarter point of the upper HU and the quarter point of the left WL of the harness 10 placed on the mounting part 51. Therefore, the gap formed between the band 61 and the harness 10 and fixing part 50 can be reduced, and the harness 10 can be band-fixed to the fixing part 50 firmly and stably.

[0065] The electrical connection box 30 configured in this way is equipped with a center case 31, an upper cover 32, and a lower cover 33 that form a storage space for accommodating a portion of the harness 10 routed to the vehicle. The center case 31, upper cover 32, and lower cover 33 are provided with an exterior holding portion 40 through which the harness 10 passes in the inward-outward direction L, and a fixing portion 50 for securing the harness 10 with a band 61 that is wrapped around the harness 10 passing through the exterior holding portion 40. The fixing portion 50 has a mounting portion 51 on which the harness 10 is placed, and an insertion passage 55 through which the harness 10 placed on the mounting portion 51 and the band 61 that is wrapped around the mounting portion 51 are inserted. The mounting portion 51 has an insertion passage 55 on the side opposite to the lower HD (upper HU) on which the harness 10 is placed, and has an insertion surface 512 on which the left side WL is lower HD than the right side WR. Furthermore, a guide surface 521 is provided on the HU side above the insertion surface 512 and on the WR side to the right of the mounting portion 51 to guide the band 61 into the insertion passage 55. The left side WL of the guide surface 521 is below HD compared to the right side WR. Here, the side into which the band 61 is inserted into the insertion passage 55 is the right side WR, and the side from which the band 61 inserted into the insertion passage 55 is removed is the left side WL.

[0066] This allows the band 61 to be easily wrapped around the harness 10 to secure it. More specifically, the mounting section 51 on which the harness 10 is placed has an insertion passage 55 through which the harness 10 placed on the mounting section 51 and the band 61 to be wrapped around the mounting section 51 are inserted from the right side WR to the left side WL, and has an insertion surface 512 where the left side WL is lower HD than the right side WR. Furthermore, a guide surface 521 is provided above the insertion surface 512 HU and to the right of the mounting section 51 WR, with the left side WL positioned lower HD than the right side WR. Therefore, after inserting the band 61 from the right side WR of the insertion passage 55, the tip portion of the band 61 inserted through the insertion passage 55 can be guided downward HD along the insertion surface 512 by bringing the band 61 into contact with the guide surface 521. This allows the tip of the band 61, which has been inserted through the insertion passage 55, to be guided to the lower HD, and the tip of the band 61 can be easily and reliably pulled out from the insertion passage 55 to the lower HD. Therefore, the harness 10 and the mounting section 51 can be easily wrapped with the band 61, and the efficiency of the wrapping work in which the harness 10 is secured with the band 61 can be improved.

[0067] Furthermore, even if the harness 10 is placed on the mounting section 51 and then the band 61 is inserted through the insertion passage 55, the tip of the band 61 can be pulled out from the left side WL of the insertion passage 55 to the downward side HD. Therefore, even after the harness 10 has been routed, the harness 10 can be secured with the band 61.

[0068] Furthermore, the exterior retaining portion 40 is provided to extend outward from the center case 31, and the fixing portion 50 is provided inside the center case 31 at the position where the exterior retaining portion 40 is provided. In this way, because the fixing portion 50 is provided inside the center case 31, the fixing portion 50 that band-secures the harness 10 can be protected. Therefore, unintended interference of the fixing portion 50 from outside the center case 31 can be prevented. In this way, because the fixing portion 50 is positioned inside the center case 31, the fixing portion 50 can be housed in the housing space of the electrical connection box 30. That is, the upper cover 32 and lower cover 33 can prevent liquid from entering the inside of the electrical connection box 30. Therefore, as would be the case if the fixing portion 50 were outside the center case 31, it can be prevented that liquid entering from the insertion passage 55 will travel along the harness 10 and enter the inside of the center case 31.

[0069] Furthermore, since the fixing portion 50 is provided at the same location as the exterior retaining portion 40, it is possible to suppress the influence of the routing direction of the harness 10 routed outside the center case 31 on the routing direction of the harness 10 routed inside the center case 31. Therefore, the harness 10 led out from the exterior retaining portion 40 can be routed in a desired direction.

[0070] Furthermore, a side wall portion 311 is provided on the left side WL of the insertion passage 55, facing the outlet 53 from which the band 61 is drawn out of the insertion passage 55. The side wall portion 311 comes into contact with the band 61 that has been inserted through the insertion passage 55, and guides the tip of the band 61 downward HD.

[0071] This allows the tip of the band 61 to be guided to the lower HD more reliably and easily. More specifically, the band 61, which has been inserted through the insertion passage 55, extends downward towards the HD as it moves from the right side WR to the left side WL. Therefore, by bringing the tip of the band 61 into contact with the side wall 311, the tip of the band 61 can be guided more reliably by the lower HD. Thus, the tip of the band 61 can be guided to the lower HD more reliably and easily.

[0072] Furthermore, by providing a side wall 311 on the left side WL of the outlet 53, the tip of the band 61 can be pulled out downward HD even if the distance between the outlet 53 and the side wall 311 is narrow. In other words, since there is no need to secure space on the left side WL of the mounting section 51 to pull out the tip of the band 61, the space on the left side WL of the side wall 311 can be effectively utilized.

[0073] Furthermore, the side wall portion 311 forms the inner circumferential surface of the center case 31. This allows the tip portion of the band 61 to be guided to the lower HD more reliably and easily with a simple structure. Also, because the tip portion of the band 61 can be pulled out to the lower HD, the fixing portion 50 can be placed near the side wall. In other words, the storage space formed by the center case 31 can be effectively utilized.

[0074] Furthermore, the insertion surface 512 and the guide surface 521 form an insertion opening 54 into the insertion passage 55 for inserting the band 61, The tip of the band 61 can be easily inserted into the insertion opening 54 formed on the left side WL of the guide surface 521. Therefore, the tip portion of the band 61 can be easily and reliably pulled out from the insertion passage 55 to the downward side HD, improving the efficiency of the winding operation in which the harness 10 is secured with the band 61.

[0075] The mounting section 51 has a mounting surface 511 on which the harness 10 is placed. The mounting surface 511 is formed in an arc shape that is recessed upward HU when viewed from the direction of wiring of the harness 10 fixed to the mounting surface 511. This allows the band 61 to be wrapped around the harness 10 and the mounting section 51 while the harness 10 is aligned with the mounting surface 511, so that the harness 10 can be firmly and stably fixed to the mounting section 51 via the band 61.

[0076] Furthermore, the mounting surface 511 is formed between the left WL of the upper HU of the harness 10 to be mounted and the left WL of the harness 10 to be mounted, when viewed from the wiring direction (inward / outward direction L). This reduces the gap formed between the band 61 wrapped around the harness 10 and the mounting portion 51, and the harness 10 and the mounting surface 511. Therefore, the harness 10 can be more firmly and stably fixed to the mounting portion 51 via the band 61.

[0077] Furthermore, the harness 10 is a wire harness made up of multiple wires bundled together, and the outer casing holding portion 40 is composed of an outer mounting portion 412 that protrudes to the outside of the center case 31 and an inner mounting portion 413 provided on the inside of the center case 31. The outer casing holding portion 40 is also provided with an outer inner circumferential surface 414 and an inner inner circumferential surface 416 on which the outer casing material 20 that covers the wire harness is placed, and the mounting portion 51 is provided with a mounting surface 511 on which the wire harness is placed. Inside the center case 31, the outer inner circumferential surface 414, the inner inner circumferential surface 416 and the mounting surface 511 are formed flush with each other.

[0078] Thus, a fixing portion 50 is provided at the same position as the exterior holding portion 40, and the outer inner circumferential surface 414 and inner inner circumferential surface 416 on which the exterior material 20 is placed, and the mounting surface 511 on which the harness 10 is placed are formed flush with each other. Therefore, the harness 10 can be placed in the central portion of the exterior material 20 that penetrates the exterior holding portion 40 and is led outward from the outer mounting portion 412. Consequently, the harness 10 can be routed in a desired direction outside the electrical connection box 30.

[0079] In this embodiment, the band 61 is inserted through the insertion passage 55 and then brought into contact with the guide surface 521. However, the band 61 may be inserted through the insertion passage 55 while it is in contact with the guide surface 521.

[0080] In the correspondence between the structure of this invention and the embodiments described above, the elongated body of this invention corresponds to the harness 10 of the embodiment, and similarly, hereinafter, The main body of the storage box corresponds to the center case 31, upper cover 32, and lower cover 33. The inward / outward direction corresponds to the inward / outward direction L. The long body passage section corresponds to the outer casing holding section 40, The band corresponds to band 61, The fixing part corresponds to the fixing part 50, The mounting section corresponds to the mounting section 51, The insertion passage corresponds to insertion passage 55, The insertion side corresponds to the left side WL, The insertion side corresponds to the right-side WR, The longer side supports HD on the lower side. The opposite side corresponds to the upper HU, The insertion surface corresponds to the insertion surface 512. The band guide surface corresponds to guide surface 521. The long-length housing box corresponds to the electrical connection box 30. The outlet corresponds to outlet 53. The opposing wall corresponds to the side wall portion 311, The insertion slot corresponds to insertion slot 54. The mounting surface corresponds to the mounting surface 511. The outer passing portion corresponds to the outer mounting portion 412, The inner passage portion corresponds to the inner mounting portion 413. Corrugated tubing is compatible with exterior material 20. The arrangement surfaces correspond to the outer inner circumferential surface 414 and the inner inner circumferential surface 416. The mounting surface corresponds to the mounting surface 511. The connection connector corresponds to connection connector 21, This invention is not limited to the configuration of the embodiments described above, and many other embodiments can be obtained.

[0081] For example, in this embodiment, the mounting portion 51 is a plate-like body with a curved arc shape, having an inner diameter equal to the outer diameter of the large-diameter portion of the exterior material 20 when viewed from the rear. However, the mounting portion 51 does not need to be arc-shaped when viewed from the rear; for example, it may be a plate-like body that slopes linearly downward towards HD as it moves from the right side WR to the left side WL.

[0082] Furthermore, if the insertion surface 512 is shaped such that it faces downward HD as it moves from WR towards the left side WL when viewed from the rear, the mounting portion 51 may have a mounting surface 511 formed on a plane parallel to the inward / outward direction L and the insertion direction W when viewed from the rear. In other words, as long as the mounting portion 51 has an insertion surface 512 that is shaped such that it faces downward HD as it moves from the right side WR towards the left side WL, the shape of the mounting surface 511 is not particularly limited. However, it is preferable that the mounting surface 511 has a shape suitable for mounting the harness 10.

[0083] Furthermore, in this embodiment, the guide portion 52 has guide surfaces 521 on the upper HU and right WR sides of the insertion surface 512. Here, it is sufficient that at least a portion of the guide surface 521 is shaped such that it faces downward HD as it moves from the right WR side towards the left WL side. That is, a portion of the guide surface 521 and the insertion surface 512 may overlap such that the left WL end of the guide surface 521 is located further to the left WL side than the right WR end of the insertion surface 512.

[0084] As described above, if a portion of the guide surface 521 and the insertion surface 512 overlap, the mounting portion 51 having the insertion surface 512 may have a mounting surface 511 that is the same shape as the inner circumferential surface 416 when viewed from the rear.

[0085] Furthermore, in this embodiment, a side wall portion 311, which is a side wall constituting the center case 31, is provided on the left side WL of the outlet 53. However, as shown in Figure 7, a vertical wall 70 may be separately provided on the left side WL of the outlet 53. As shown in Figure 7(a), the vertical wall 70 is erected from the side wall of the outer side LA of the center case 31 toward the inner side LB, and faces the outlet 53 on the left side WL of the outlet 53. More specifically, it faces at least the lower side HD of the outlet 53. The vertical wall 70 is inclined so as it approaches the lower side HD, it comes closer to the end of the left side WL of the mounting section 51.

[0086] Since the vertical wall 70 configured in this way is positioned opposite the outlet 53, the band 61, with its tip inserted into the insertion opening 54, is guided through the insertion passage 55 to the left WL and the lower HD by contacting the guide surface 521. The tip of the band 61 inserted from the outlet 53 toward the left WL also comes into contact with the vertical wall 70. The tip of the band 61 that comes into contact with the vertical wall 70 is guided along the vertical wall 70 toward the lower HD, so the tip of the band 61 can be easily led out to the lower HD of the center case 31 (see Figure 7(b)).

[0087] As the vertical wall 70 is inclined to approach the left end of the mounting section 51 WL as it moves downward towards the HD, the tip of the band 61 can be guided more reliably toward the downward HD by bringing the band 61 into contact with the vertical wall. Therefore, the workability of winding the band 61 around the harness 10 and the mounting section 51 can be further improved.

[0088] In the above-described embodiment, the upright wall 70 is inclined to approach the end of the left side WL of the mounting section 51 as it moves toward the downward HD, but it is not necessarily required to have this shape. For example, the shape of the upright wall 70 is not limited as long as it can more reliably guide the tip portion of the band 61 toward the downward HD, and it may even be aligned with the height direction H.

[0089] For example, in this embodiment, the long-length housing box of this invention is an electrical connection box 30 that houses one end of the harness 10 and connects electrical equipment, but it is not limited to this. For example, it may be a protector that protects a long-length object such as the harness 10, such as a protector that prevents the harness 10 routed in a vehicle from interfering with other components. The electrical connection box 30 includes junction boxes, fuse boxes, relay boxes, etc., which are mounted on vehicles. [Explanation of Symbols]
