Description

[Technical field]

[0001] The present invention relates to a fixing structure for fixing, for example, a wire harness to an electric junction box using a fixing member, and to an electric junction box. [Background technology]

[0002] 2. Description of the Related Art Conventionally, when a predetermined component such as a wire harness is attached to a receiving component such as a vehicle, the predetermined component is fixed to the receiving component by using a fixing member that engages with an insertion portion of the receiving component. For example, Patent Document 1 discloses a band clamp (clamp 1) that includes, as a fixing member, a band portion (band body 20) that is wrapped around the outer circumference of a wire harness and an anchor portion (insertion protrusion 51) that is engaged with an insertion portion of a vehicle.

[0003] Such a band clamp bundles and holds a plurality of wire harnesses, and fixes the held plurality of wire harnesses integrally to the vehicle, thereby regulating the routing path of the plurality of wire harnesses.

[0004] Incidentally, for example, when two wire harnesses are branched off toward respective devices to which they are to be connected, it is necessary to provide two insertion portions to which the respective wire harnesses are attached on the mounting member near the branch point of the wire harnesses in order to regulate the routing path of the branched wire harnesses.

[0005] However, the same band clamp as in Patent Document 1 is often used for multiple insertion parts of the workpiece, which means that an operator may use the band clamp on an insertion part other than the desired insertion part of the workpiece, resulting in an unintended malfunction.

[0006] For example, if an operator fastens one wire harness to an insertion portion for attaching the other wire harness, the wire harness may be routed in an incorrect path, resulting in a problem that the wire harness cannot be connected to an appropriate device. Therefore, at the site where a specific component is attached to a workpiece, a fixing structure is required that can prevent erroneous assembly of a fixing component to an insertion portion of the workpiece.

[0007] [Patent Document 1] JP 2013-141378 A Summary of the Invention [Problem to be solved by the invention]

[0008] SUMMARY OF THE PRESENT DISCLOSURE In view of the above problems, an object of the present invention is to provide a fixing structure and an electrical junction box that can prevent erroneous installation of a fixing member to an insertion portion of a workpiece. [Means for solving the problem]

[0009] This invention relates to a fixing structure which is comprised of a fixing member for fixing a specific member and an insertion portion of a member to which the specific member is to be attached, and in which an anchor portion of the fixing member is engaged with the insertion portion along an insertion direction, the anchor portion of the fixing member being provided with a concave insertion hole formed along the insertion direction, and the insertion portion of the member to be attached being comprised of a seat portion having an insertion hole into which the anchor portion is inserted along the insertion direction, an accommodation space in which the anchor portion inserted through the insertion hole is accommodated, and a protruding portion which protrudes toward the accommodation space and is inserted along the insertion direction into the concave insertion hole provided in the fixing member. The insertion portion of the mounting member is provided with an opposing surface portion that faces the seat portion across the accommodation space in the insertion direction, and the anchor portion of the fixing member is formed with a length in the insertion direction such that, when the anchor portion is engaged with the insertion portion, the protruding portion is inserted into the insertion hole and the tip does not abut against the opposing surface portion. It is characterized by:

[0010] The fixing member may be a member such as a band clamp that holds a specified member and engages with the insertion portion of the workpiece, or a clip-like member for fixing the holding member that holds the specified member to the insertion portion of the workpiece. The insertion hole may be, for example, an opening extending in the insertion direction, or a groove-shaped hole.

[0011] According to this invention, the fixing structure can prevent erroneous installation of the fixing member to the insertion portion of the workpiece. Specifically, when an insertion hole of an appropriate shape is provided in the anchor portion, the fixing member can be engaged with the insertion portion of the attached member.

[0012] On the other hand, if the anchor portion does not have an insertion hole or has an inappropriate shape such that the insertion hole does not correspond to the protrusion portion of the insertion portion, the anchor portion will abut against the protrusion portion of the insertion portion, preventing the fixing member from being inserted into the insertion hole.

[0013] This allows the fixing structure to prevent an inappropriately shaped fixing member from being locked into the insertion portion of the workpiece. Therefore, the fixing structure can prevent an inappropriately shaped fixing member from being erroneously assembled to the insertion portion of the workpiece.

[0014] In addition, the insertion portion of the attached member is provided with an opposing surface portion that faces the seat portion in the insertion direction across the storage space, and the anchor portion of the fixing member is formed to a length in the insertion direction such that, when engaged with the insertion portion, the protrusion portion is inserted into the insertion hole and the tip does not abut against the opposing surface portion.

[0015] This allows the fixing member to be engaged with the insertion portion of the workpiece when the fixing member has an appropriate length in the insertion direction such that the anchor portion does not come into contact with the opposing surface of the insertion portion. On the other hand, if the anchor portion has an inappropriate shape that is longer than the appropriate length in the insertion direction, the anchor portion of the inappropriately shaped fixing member will abut against the opposing surface of the insertion portion, preventing the attachment of the attached member to the insertion portion. This makes it possible for the fixing structure to prevent a fixing member with an anchor portion of an inappropriate length from being erroneously attached to the insertion portion of the workpiece.

[0016] As an aspect of the present invention, the protruding portion of the attached member may be disposed approximately in the center of the insertion hole when viewed from the insertion direction. According to this configuration, the fixing structure can better prevent erroneous assembly of the fixing member without impairing the ease of assembly of the fixing member.

[0017] Specifically, if a protrusion portion is arranged on the periphery of the insertion hole when viewed from the insertion direction, when the anchor portion of the fixing member is inserted into the insertion hole of the insertion portion from a direction inclined relative to the insertion direction, there is a risk that the anchor portion will not come into contact with the protrusion portion depending on the insertion direction.

[0018] In contrast, by locating the protruding portion approximately in the center of the insertion hole, the fixing structure can ensure that, for example, an anchor portion that does not have an insertion hole can contact the protruding portion regardless of the direction of insertion. Therefore, the fixing structure can prevent a fixing member of an inappropriate shape from being erroneously locked into the insertion portion of the attached member.

[0019] Furthermore, the fixing structure improves the visibility of the protruding portion compared to when the protruding portion is disposed on the opening edge of the insertion hole when viewed from the insertion direction. Therefore, the worker can assemble the fixing member to the insertion portion of the workpiece while checking the presence or absence of the protruding portion, as well as the shape and orientation of the protruding portion. As a result, the fixing structure can better prevent erroneous assembly of a fixing member having an inappropriate shape without impairing the ease of assembly of the fixing member.

[0020] In another aspect of the invention, the insertion hole of the fixing member is configured as an opening extending from the tip surface of the anchor portion in a direction opposite to the insertion direction, and the protruding portion of the insertion portion extends in a direction opposite to the insertion direction and, in a cross-section along the insertion direction, may be formed into a cross-sectional shape having a tip that tapers toward the direction opposite to the insertion direction.

[0021] According to this configuration, the fixing structure can easily insert the protrusion portion into the insertion hole even when, for example, the anchor portion of the fixing member is inserted into the insertion hole of the insertion portion from a direction inclined relative to the insertion direction.

[0022] Therefore, the fixing structure can simultaneously prevent erroneous installation of a fixing member having an inappropriate shape and improve the ease of installation of the fixing member to the insertion portion.

[0023] In another aspect of the present invention, the insertion hole of the insertion portion may be formed in an approximately elongated elliptical shape when viewed from the insertion direction, and the protrusion portion of the insertion portion and the insertion hole of the fixing member may be formed in an elongated shape in the major axis or minor axis direction of the insertion hole.

[0024] According to this configuration, the fixing structure can reliably prevent erroneous assembly of a fixing member having an inappropriate shape, as compared with, for example, a protrusion and an insertion hole that are substantially circular when viewed from the insertion direction. Specifically, the fixing structure can prevent a fixing member with an insertion hole long in the short axis direction from being assembled to an insertion portion of a workpiece having a protruding portion long in the long axis direction. Alternatively, the fixing structure can prevent a fixing member with an insertion hole long in the long axis direction from being assembled to an insertion portion of a workpiece having a protruding portion long in the short axis direction.

[0025] In another aspect of the invention, the anchor portion of the fixing member may be arranged opposite to the expansion direction perpendicular to the insertion direction, and may be provided with a pair of locking claws that are engaged with the insertion portion by expanding in the expansion direction in the storage space, and the insertion portion of the attached member may be arranged opposite to the storage space in an orthogonal direction perpendicular to the expansion direction when viewed from the insertion direction, and may be provided with a pair of expansion restricting portions that restrict expansion of the locking claws in the orthogonal direction.

[0026] According to this configuration, a fixing member having an appropriate shape in which a pair of locking claws face each other in the deployment direction can be locked to the insertion portion of the workpiece. On the other hand, in the case of a fixing member of an inappropriate shape in which a pair of locking claws face each other in a direction perpendicular to the deployment direction, the deployment of the locking claws is hindered by the deployment restricting portion of the insertion portion, and the fixing member cannot be locked to the insertion portion of the attached member.

[0027] As a result, the fixing structure can more reliably prevent erroneous assembly of a fixing member of an inappropriate shape, even if an insertion hole is provided in a fixing member of an inappropriate shape, by means of the protrusion portion of the insertion portion and the expansion restricting portion of the insertion portion.

[0028] As a further aspect of the present invention, the fixing member may be provided with a substantially belt-shaped band portion that is wound around an outer periphery of the predetermined member to hold the predetermined member. With this configuration, the fixing structure can reduce the increase in the number of parts compared to a configuration in which, for example, a specified member is held by a retaining member and the retaining member is fixed to the insertion portion of the attached member using a fixing member separate from the retaining member.

[0029] Furthermore, the fixing structure allows the fixing member to be attached to the specified member in advance, making it easier to attach the specified member to the insertion portion and improving the ease of assembly of the specified member to the insertion portion of the attached member.

[0030] The present invention is also characterized in that it comprises the above-mentioned fixing structure and a roughly box-shaped connection box main body, the member to which the insertion portion of the fixing structure is provided is the connection box main body, and the insertion portion is an electrical connection box arranged on the outer surface portion of the connection box main body.

[0031] The electric connection box refers to a junction box that relays or branches electric wires such as wire harnesses, or a control device that transmits and receives various information to and from a device connected to one end of the electric wires.

[0032] According to the present invention, the electrical junction box can prevent a member other than the desired predetermined member from being attached to the insertion portion. Therefore, for example, when the predetermined member is a wire harness, the electrical junction box can prevent the wire harness from being restricted to an incorrect routing path.

[0033] In one aspect of the present invention, the fixing member of the fixing structure is a first fixing member, and the insertion portion of the fixing structure is a first insertion portion, and the connection box body has a substantially oblong insertion hole into which the first fixing member is inserted, and is provided with the first insertion portion to which the first fixing member is engaged, and a second insertion portion that is arranged on an outer surface portion different from the first insertion portion and to which a second fixing member for fixing a predetermined member is engaged via the substantially oblong insertion hole, and the first fixing member is oriented in a direction parallel to a minor axis of the substantially oblong shape or The first insertion portion may be provided with a pair of locking claws that are engaged with the first insertion portion by expanding in one direction of the long axis, and the second fixing member may be provided with a pair of locking claws that are engaged with the second insertion portion by expanding in the other direction of the short axis or the long axis of the approximately oblong shape, the first insertion portion may be provided with a pair of expansion restricting portions that restrict the expansion of the locking claws in the other direction of the short axis or the long axis, and the second insertion portion may be provided with a pair of expansion restricting portions that restrict the expansion of the locking claws in one direction of the short axis or the long axis.

[0034] The predetermined member fixed by the second fixing member refers to a predetermined member that is the same as the predetermined member fixed by the first fixing member, or a predetermined member that is different from the predetermined member fixed by the first fixing member. According to this configuration, the electrical junction box can prevent the second fixing member from being assembled to the first insertion portion and the first fixing member from being assembled to the second insertion portion. Therefore, even when the electrical junction box is provided with the first insertion portion and the second insertion portion, it is possible to prevent erroneous assembly of the first fixing member and the second fixing member. Effect of the Invention

[0035] The present invention can provide a fixing structure and an electrical junction box that can prevent erroneous installation of a fixing member to an insertion portion of a workpiece. [Brief description of the drawings]

[0041] In addition, the arrow X in the figure indicates the front-to-rear direction of the electrical junction box 3 (hereinafter referred to as the front-to-rear direction X), with the direction toward the left in FIG. 1 being the front side Xf and the direction toward the right in FIG. 1 being the rear side Xr. 1 is the upper side of the electrical junction box 3, and the lower side of FIG.

[0042] In addition, the arrow Y in the figure indicates a direction perpendicular to the front-to-rear direction X when viewed in a plane (hereinafter referred to as the width direction Y), with the direction toward the right in FIG. 1 being one width direction side YR, and the direction toward the left in FIG. 1 being the other width direction side YL.

[0043] As shown in FIG. 1, this embodiment is composed of an electrical junction box 3 to which a first wire harness 1 and a second wire harness 2 are attached, a first fixing member 10 for fixing the first wire harness 1 to the electrical junction box 3, and a second fixing member 20 for fixing the second wire harness 2 to the electrical junction box 3.

[0044] First, as shown in FIG. 1, the first wire harness 1 and the second wire harness 2 are arranged adjacent to the electric junction box 3 so as to run along the side surface on one width direction side YR and the front surface of the electric junction box 3.

[0045] Specifically, as shown in FIG. 1, the first wire harness 1 is routed along the side surface of one widthwise side YR of the electrical junction box 3 toward the forward side Xf, and then routed downward near the front of the electrical junction box 3.

[0046] On the other hand, as shown in FIG. 1, the second wire harness 2 is arranged along the side surface of one widthwise side YR of the electrical connection box 3 toward the forward side Xf, and then is arranged around to the front of the electrical connection box 3 toward the other widthwise side YL.

[0047] As shown in FIG. 1, the first wire harness 1 and the second wire harness 2 have their portions routed toward the forward side Xf bundled together, for example, with an adhesive tape T, and branch off near the front of the electrical junction box 3.

[0048] Although detailed illustration is omitted, the electrical junction box 3 is composed of a substantially box-shaped junction box main body 30, and a circuit board, fuse, bus bars, etc. housed and held inside the junction box main body 30. As shown in Figures 1 and 2, the junction box main body 30 of this electrical junction box 3 is composed of an upper box main body part 30a located above and a lower box main body part 30b located below the upper box main body part 30a, which are assembled in the vertical direction.

[0049] As shown in Figs. 1 and 2, the electric junction box 3 is provided with a first insertion portion 31 to which the first wire harness 1 is attached, and a second insertion portion 32 to which the second wire harness 2 is attached.

[0050] Specifically, as shown in Fig. 1, the first insertion portion 31 is formed below the front part of the box body lower part 30b so as to form a side portion of one widthwise side YR of the electrical connection box 3. As shown in Figs. 1 and 2, the first fixing member 10 (anchor portion 12 of the first fixing member 10 described later) is engaged with this first insertion portion 31 along the direction toward the other widthwise side YL.

[0051] 1, the second insertion portion 32 is formed in the front portion of the box body upper portion 30a so as to form a front portion of the electrical connection box 3. As shown in FIGS. 1 and 2, the second insertion portion 32 is engaged with the second fixing member 20 (anchor portion 22 of the second fixing member 20 described later) along a direction toward the rear side Xr.

[0052] Next, the fixing structure between the first insertion portion 31 of the electric junction box 3 and the first fixing member 10 will be described in more detail. First, as shown in FIG. 1, the first fixing member 10 is a member that holds a portion of the first wire harness 1 that extends in the vertical direction, and fixes the first wire harness 1 to the first insertion portion 31 of the electric junction box 3.

[0053] As shown in Figures 2 and 3, this first fixing member 10 is composed of a clamp body 11 that holds the first wire harness 1, and an anchor portion 12 that engages with the first insertion portion 31 of the electrical connection box 3. The clamp body 11 has substantially the same structure as a so-called cable tie. As shown in Figures 2 and 3, the clamp body 11 is composed of a substantially rectangular base portion 11a when viewed from the width direction Y, and a substantially band-shaped band portion 11b extending in the width direction Y from the front end side of the base portion 11a.

[0054] The base portion 11a is curved toward the rear side Xr, and a band portion 11b, which is wound around the outer peripheral surface of the first wire harness 1, is inserted toward the front side Xf, and a lock portion (not shown) is provided to engage the band portion 11b.

[0055] As shown in FIG. 3, the anchor portion 12 is composed of an anchor shaft 13 extending from the base portion 11a toward the other width direction side YL, an umbrella portion 14 extending wide from the base of the anchor shaft 13, and a pair of locking claws 15 extending from the anchor shaft 13.

[0056] 3, the anchor shaft 13 has a generally oblong shape when viewed in the width direction Y, and is disposed so that the long axis direction of the generally oblong shape is the up-down direction. Furthermore, the anchor shaft 13 is formed so that the vicinity of the tip thereof becomes tapered toward the other width direction side YL.

[0057] As shown in FIG. 5, when the anchor shaft 13 is engaged with the first insertion portion 31, the protrusion portion 313 of the first insertion portion 31 is inserted into the insertion hole 13b described later, and the tip of the protrusion portion 313 is formed to a length in the width direction Y such that it does not come into contact with the opposing surface portion 312 of the first insertion portion 31.

[0058] As shown in Figures 3 to 6, such an anchor shaft body 13 is formed with a through hole 13a that opens along the front-rear direction X (short axis direction) and an insertion hole 13b that opens along the width direction Y. Specifically, as shown in Figures 3 to 6, the through hole 13a has a generally rectangular shape when viewed from the front that is long in the width direction Y, and is formed so as to penetrate in the front-rear direction X (short axis direction) between opposing surfaces in the short axis direction of the anchor shaft body 13.

[0059] On the other hand, the insertion hole 13b is an opening into which a protruding portion 313 of the first insertion portion 31 described later is inserted, and is formed in the tip surface of the anchor shaft 13. As shown in Figures 3 to 6, this insertion hole 13b has a generally oblong shape that is long in the up-down direction when viewed from the width direction Y, and is formed to have a length in the width direction Y from the tip surface of the anchor shaft 13 to the umbrella portion 14.

[0060] 3, the umbrella portion 14 extends from the base of the anchor shaft 13 so as to spread out toward the other widthwise side YL and in all four directions. Therefore, the umbrella portion 14 is formed in a generally oblong shape that is larger in diameter than the anchor shaft 13 when viewed from the widthwise direction Y and is long in the up-down direction.

[0061] 3 to 5, the pair of locking claws 15 are disposed opposite each other in the front-rear direction X, and are formed so as to be able to lock onto the first insertion portion 31 by expanding in the front-rear direction X. In other words, the pair of locking claws 15 are disposed opposite each other in the short axis direction of the anchor shaft body 13, and are formed so as to be able to lock onto the first insertion portion 31 by expanding in the short axis direction.

[0062] Specifically, as shown in Figures 3, 5, and 6, the pair of locking claws 15 are arranged in the through hole 13a so as to face each other across the insertion hole 13b of the anchor shaft 13. The pair of locking claws 15 have their ends on the other widthwise side YL connected to the edge of the through hole 13a on the other widthwise side YL, and are formed so as to elastically deform and expand in the short axis direction of the anchor shaft 13, i.e., in the front-rear direction X.

[0063] Furthermore, as shown in Figures 3 and 5, on the front surface of the locking claw 15 on the front side Xf and on the rear surface of the locking claw 15 on the rear side Xr, an inclined surface 15a continuing to the anchor shaft body 13 and a stepped surface 15b extending in a stepped manner from the inclined surface 15a are formed in this order from the other widthwise side YL. As shown in FIG. 5, the stepped surface 15b of the locking claw 15 is formed as a portion that is locked to a first insertion portion 31, which will be described later.

[0064] More specifically, the locking claw 15 on the front side Xf has an inclined surface 15a formed as a substantially flat surface inclined from the connection point with the anchor shaft 13 toward the front side Xf and one widthwise side YR, and the stepped surface 15b is formed in a stepped shape from the inclined surface 15a toward the rear side Xr and one widthwise side YR.

[0065] On the other hand, the locking claw 15 on the rear side Xr has an inclined surface 15a formed as a substantially flat surface inclined from the connection point with the anchor shaft 13 toward the rear side Xr and one widthwise side YR, and a stepped surface 15b formed in a stepped shape from the inclined surface 15a toward the front side Xf and one widthwise side YR.

[0066] 5 to 7, the first insertion portion 31 of the electrical connection box 3 is composed of a seat portion 311 forming a side portion of the connection box main body 30, an opposing surface portion 312 opposing the seat portion 311, a storage space S1 formed between the seat portion 311 and the opposing surface portion 312, a protrusion portion 313 protruding toward the storage space S1, and a pair of deployment restricting portions 314.

[0067] As shown in Figures 5 and 7, the seat portion 311 is flat and has a thickness in the width direction Y, and has an insertion hole 311a formed therein, into which the anchor portion 12 of the first fixing member 10 is inserted, from one width side YR to the other width side YL. As shown in Figs. 2 and 7, the insertion hole 311a has a generally oblong shape and is generally the same size as the anchor shaft body 13, and is formed to open so that the major axis direction of the generally oblong shape is in the up-down direction.

[0068] 5 to 7, the facing surface portion 312 is spaced a predetermined distance from the seating surface portion 311 on the other widthwise side YL, and is formed at a position where it does not come into contact with the anchor portion 12 of the first fixing member 10. The facing surface portion 312 has a surface facing the seating surface portion 311 formed to be substantially flat.

[0069] 5 and 7, the accommodation space S1 is a space defined by the seat surface portion 311 and the opposing surface portion 312. This accommodation space S1 is configured as a deployment space in which the anchor portion 12 of the first fixing member 10 inserted through the insertion hole 311a is accommodated and in which the pair of locking claws 15 of the anchor portion 12 are deployed.

[0070] As shown in Figures 5 and 6, the protrusion portion 313 is positioned so as to be located approximately in the center of the insertion hole 311a when viewed from the width direction Y, and is formed so that the insertion hole 13b of the first fixing member 10 can be inserted from one width direction side YR to the other width direction side YL.

[0071] In detail, as shown in Figures 5 to 7, the protrusion portion 313 is a generally rectangular shape that is elongated in the major axis direction of the insertion hole 311a when viewed from the width direction Y, and is erected from the opposing surface portion 312 toward one width direction side YR. As shown in Figures 5 and 6, this protrusion 313 is formed so that in a horizontal cross section along the front-rear direction X and in a vertical cross section along the width direction Y, the vicinity of the tip becomes tapered toward one width direction side YR.

[0072] 6 to 8, the pair of deployment restricting portions 314 are disposed facing each other in the longitudinal direction of the insertion hole 311a, i.e., in the up-down direction, in the accommodation space S1. The pair of deployment restricting portions 314 are fixing members different from the first fixing member 10, and when a fixing member having a locking claw that deploys in the longitudinal direction of the insertion hole 311a is inserted into the insertion hole 311a, the pair of deployment restricting portions 314 restrict deployment of the locking claw in the longitudinal direction of the insertion hole 311a.

[0073] More specifically, as shown in FIGS. 7 and 8, the pair of deployment restricting portions 314 are disposed opposite to each other in the vertical direction with the protruding portion 313 therebetween. Of the pair of deployment restricting portions 314, the upper deployment restricting portion 314a located at the top is formed at a position above and toward the rear side Xr with respect to the anchor shaft body 13 of the first fixing member 10 engaged with the first insertion portion 31, as shown in Figure 8.

[0074] Specifically, as shown in Figures 7 and 8, the upper deployment restricting portion 314a is plate-shaped having a thickness in the front-rear direction X, and is erected from the seat portion 311 to the opposing surface portion 312 so that its lower side surface (hereinafter referred to as the lower surface) fits along the edge surface of the insertion hole 311a.

[0075] For this reason, as shown in FIG. 8, the lower surface of the upper deployment restricting portion 314a is close to the curved surface of the anchor shaft 13 in a vertical cross section along the front-to-rear direction X, and is formed in a curved shape along the curved surface of the anchor shaft 13.

[0076] On the other hand, of the pair of deployment restricting portions 314, the lower deployment restricting portion 314b located on the lower side is formed at a position substantially in the center in the front-to-rear direction X relative to the anchor shaft body 13 of the first fixing member 10 engaged with the first insertion portion 31, as shown in FIG. 8.

[0077] Specifically, as shown in Figures 7 and 8, the lower deployment restricting portion 314b is plate-shaped having a thickness in the front-rear direction X, and is erected from the seat portion 311 to the opposing surface portion 312 so that its upper side surface (hereinafter referred to as the top surface) fits along the edge surface of the insertion hole 311a.

[0078] For this reason, as shown in FIG. 8, the upper surface of the lower deployment restricting portion 314b is close to the curved surface of the anchor shaft 13 in a vertical cross section along the front-to-rear direction X, and is formed in a curved shape along the curved surface of the anchor shaft 13.

[0079] Next, the fixing structure between the second insertion portion 32 of the electric junction box 3 and the second fixing member 20 will be described in detail. First, as shown in FIG. 1, the second fixing member 20 is a member that holds a portion of the second wire harness 2 extending in the width direction Y and fixes the second wire harness 2 to the second insertion portion 32 of the electrical junction box 3. As shown in Figures 2 and 9, this second fixing member 20 is composed of a clamp body 21 that holds the second wire harness 2, and an anchor portion 22 that engages with the second insertion portion 32 of the electrical connection box 3.

[0080] As shown in FIGS. 2 and 9, the clamp body 21 is composed of a substantially rectangular base portion 21a and a substantially belt-shaped band portion 21b extending from the base portion 21a. On the other hand, as shown in FIG. 9, the anchor portion 22 is composed of an anchor shaft 23 extending rearward from the base portion 21a, an umbrella portion 24 extending wide from the base of the anchor shaft 23, and a pair of locking claws 25 extending from the anchor shaft 23.

[0081] In such a second fixing member 20, the clamp body 21, anchor shaft body 23, and umbrella portion 24 are formed in approximately the same size and shape as the first fixing member 10 in a state where the first fixing member 20 is rotated 90 degrees clockwise in a plan view with the up-down direction as the rotation axis and further rotated 90 degrees counterclockwise in a front-to-back direction X as the rotation axis, and the pair of locking claws 25 are formed in different positions.

[0082] The base portion 21a and the band portion 21b of the clamp body 21 have substantially the same configuration and size as the base portion 11a and the band portion 11b of the first fixing member 10, and therefore a detailed description thereof will be omitted. 9, the anchor shaft 23 of the anchor part 22 has a generally elongated elliptical shape in rear view and is generally the same size as the anchor shaft 13 of the first fixing member 10, and is formed so that the vicinity of the tip becomes thinner toward the rear side Xr. This anchor shaft 23 is inserted into the second insertion part 32 with the long axis direction of the generally elongated elliptical shape being the width direction Y.

[0083] As shown in FIG. 10, the anchor shaft 23 is formed to have a length in the front-rear direction X such that, when engaged with the second insertion portion 32, its tip does not abut against the opposing surface portion 322 of the second insertion portion 32 described later.

[0084] 9 to 11, the anchor shaft 23 has a through hole 23a that opens along the width direction Y (longitudinal direction). However, the anchor shaft 23 does not have an opening corresponding to the insertion hole 13b of the first fixing member 10. Specifically, as shown in Figures 9 and 10, the through hole 23a is a generally rectangular shape that is long in the front-to-rear direction X when viewed from the width direction Y, and is formed so as to penetrate in the width direction Y between opposing surfaces in the long axis direction (width direction Y) of the anchor shaft body 23.

[0085] 9, the umbrella portion 24 extends from the base of the anchor shaft 23 so as to widen in all directions toward the rear side Xr. For this reason, the umbrella portion 24 is formed in a generally elongated elliptical shape in rear view that is larger in diameter than the anchor shaft 23 and longer in the width direction Y.

[0086] 9, 11, and 12, the pair of locking claws 25 are disposed opposite each other in the width direction Y within the through hole 23a, and are formed so as to be able to lock onto the second insertion portion 32 by expanding in the width direction Y. In other words, the pair of locking claws 25 are disposed opposite each other in the longitudinal direction of the anchor shaft 23, and are formed so as to be able to lock onto the second insertion portion 32 by expanding in the longitudinal direction.

[0087] Specifically, as shown in Figures 9 and 11, the pair of locking claws 25 have their ends on the rear side Xr connected to the rear edge of the through hole 23a and are formed so as to elastically deform and expand in the longitudinal direction of the anchor shaft 23, i.e., in the width direction Y. Similar to the locking claws 15 of the first fixing member 10, the pair of locking claws 25 are formed with an inclined surface 25a and a stepped surface 25b, and the stepped surface 25b is locked to a second insertion portion 32 which will be described later.

[0088] 10 to 12, the second insertion portion 32 of the electrical connection box 3 is composed of a seat portion 321 forming the front portion of the connection box main body 30, an opposing surface portion 322 opposing the seat portion 321, a storage space S2 formed between the seat portion 321 and the opposing surface portion 322, and a pair of deployment restricting portions 323 protruding toward the storage space S2.

[0089] As shown in FIG. 11, the seat portion 321 is a flat plate having a thickness in the front-rear direction X, and has an insertion hole 321a formed therein, into which the anchor portion 22 of the second fixing member 20 is inserted, extending from the front side Xf toward the rear side Xr. As shown in Figures 2, 10 and 11, this insertion hole 321a has a substantially elongated elliptical shape of substantially the same size as the insertion hole 311a of the first insertion portion 31, and is opened so that the major axis direction of the substantially elongated elliptical shape is the width direction Y.

[0090] 11, the facing surface portion 322 is spaced a predetermined distance from the seating surface portion 321 toward the rear side Xr and is formed at a position where it does not come into contact with the anchor portion 22 of the second fixing member 20. The facing surface portion 322 has a surface facing the seating surface portion 321 formed to be substantially flat.

[0091] 11, the accommodation space S2 is a space defined by the seat surface portion 321 and the opposing surface portion 322. This accommodation space S2 is configured as an expansion space in which the anchor portion 22 of the second fixing member 20 inserted through the insertion hole 321a is accommodated and in which the pair of locking claws 25 of the anchor portion 22 are expanded.

[0092] 10 and 12, the pair of deployment restricting portions 323 are disposed facing each other in the short axis direction of the insertion hole 321a, i.e., in the up-down direction, in the accommodation space S2. The pair of deployment restricting portions 323 are fixing members different from the second fixing member 20, and when a fixing member having a locking claw that deploys in the short axis direction of the insertion hole 321a is inserted into the insertion hole 321a, the pair of deployment restricting portions 323 restrict deployment of the locking claw in the short axis direction of the insertion hole 321a.

[0093] 10 and 12, the pair of deployment restricting portions 323 are disposed facing each other in the vertical direction with the anchor portion 22 of the engaged second fixing member 20 therebetween. The pair of deployment restricting portions 323 are plate-shaped with a thickness in the vertical direction, and are erected from the seat portion 321 to the facing surface portion 322 so that the surfaces facing each other in the vertical direction are along the edge surface of the insertion hole 321a.

[0094] For this reason, as shown in FIG. 12, in a vertical cross section along the width direction Y, the surfaces of the pair of deployment restricting portions 323 that face each other in the up-down direction are close to planes that face each other in the short axis direction of the anchor shaft body 23 of the second fixing member 20, and are formed on planes that are approximately parallel to the plane of the anchor shaft body 13.

[0095] Due to this configuration, when a fixing member that does not correspond to the first insertion portion 31, for example, the second fixing member 20, is inserted into the insertion hole 311a of the first insertion portion 31, the insertion of the second fixing member 20 into the insertion hole 311a and the deployment of the locking claws 25 are restricted by the protrusion portion 313 of the first insertion portion 31 and a pair of deployment restricting portions 314, and the second fixing member 20 is prevented from engaging with the first insertion portion 31.

[0096] In addition, when the first fixing member 10 is inserted into the insertion hole 321a of the second insertion portion 32, the deployment of the locking claws 15 of the first fixing member 10 is restricted by a pair of deployment restricting portions 323 of the second insertion portion 32, and the first fixing member 10 is prevented from being locked into the second insertion portion 32. In this manner, the fixing structure of the present embodiment regulates the first wire harness 1 and the second wire harness 2 to their respective desired wiring paths.

[0097] The fixing structure of this embodiment as described above is composed of a first fixing member 10 for fixing the first wire harness 1 and a first insertion portion 31 of the connection box main body 30 to which the first wire harness 1 is attached, and the anchor portion 12 of the first fixing member 10 is engaged with the first insertion portion 31 along the other widthwise side YL.

[0098] In the fixing structure of this embodiment, the anchor portion 12 of the first fixing member 10 is provided with an insertion hole 13b formed along the other widthwise side YL. The first insertion portion 31 of the connection box body 30 includes a seat portion 311 having an insertion hole 311a into which the anchor portion 12 is inserted along the other widthwise side YL.

[0099] Furthermore, the first insertion portion 31 has a storage space S1 in which the anchor portion 12 inserted through the insertion hole 311a is accommodated, and a protruding portion 313 that protrudes toward the storage space S1 and is inserted along the other widthwise side YL into the insertion hole 13b provided in the first fixing member 10.

[0100] As a result, the fixing structure of the present embodiment can prevent erroneous assembly of the second fixing member 20 to the first insertion portion 31 of the junction box body 30. Specifically, since the anchor portion 22 is provided with an insertion hole 13b of an appropriate shape, the first fixing member 10 can be locked into the first insertion portion 31 of the connection box body 30.

[0101] On the other hand, in the case of the second fixing member 20 in which no insertion hole is provided in the anchor portion 22, the anchor portion 22 comes into contact with the protruding portion 313 of the first insertion portion 31, so that insertion into the insertion hole 311a is hindered.

[0102] Thereby, the fixing structure of this embodiment can prevent the second fixing member 20 having an inappropriate shape from being locked into the first insertion portion 31 of the junction box main body 30. Therefore, the fixing structure of this embodiment can prevent the second fixing member 20 from being erroneously assembled to the first insertion portion 31 of the junction box main body 30.

[0103] Further, the protruding portion 313 of the junction box body 30 is disposed approximately in the center of the insertion hole 311a when viewed from the width direction Y. According to this configuration, the fixing structure of the present embodiment can further prevent erroneous assembly of the second fixing member 20 without impairing the ease of assembly of the first fixing member 10.

[0104] Specifically, when a protrusion portion is arranged on the periphery of the insertion hole 311a when viewed from the other width direction side YL, when the anchor portion 22 of the second fixing member 20 is inserted into the insertion hole 311a of the first insertion portion 31 from a direction inclined relative to the width direction Y, there is a risk that the anchor portion 22 will not come into contact with the protrusion portion depending on the insertion direction.

[0105] In contrast, by locating protruding portion 313 approximately in the center of insertion hole 311a, the fixing structure of this embodiment can reliably bring anchor portion 22 of second fixing member 20 into contact with protruding portion 313 regardless of the insertion direction. Therefore, the fixing structure of this embodiment can prevent second fixing member 20 of an inappropriate shape from being erroneously locked into first insertion portion 31 of connection box main body 30.

[0106] Furthermore, the fixing structure of this embodiment can improve the visibility of the protruding portion 313 compared to a case in which the protruding portion is disposed on the opening edge of the insertion hole 311a when viewed from the other width direction side YL. Therefore, the worker can assemble the first fixing member 10 to the first insertion portion 31 of the connection box main body 30 while checking the presence or absence of the protruding portion 313 and the shape and orientation of the protruding portion 313. As a result, the fixing structure of the present embodiment can further prevent erroneous assembly of the second fixing member 20 without impairing the ease of assembly of the first fixing member 10.

[0107] The first insertion portion 31 of the connection box body 30 is provided with an opposing surface portion 312 that faces the seat portion 311 on the other widthwise side YL across the accommodation space S1. The anchor portion 12 of the first fixing member 10 is formed to have a length in the widthwise direction Y such that, when engaged with the first insertion portion 31, the protruding portion 313 is inserted into the insertion hole 13b and the tip does not abut against the opposing surface portion 312.

[0108] According to this configuration, the first fixing member 10 can be engaged with the first insertion portion 31 of the connection box main body 30 when it has an appropriate length in the width direction Y such that the anchor portion 12 does not abut against the opposing surface portion 312 of the first insertion portion 31. On the other hand, if the anchor portion has an inappropriate shape that is longer than the appropriate length in the width direction Y, the anchor portion of the inappropriately shaped fixing member will abut against the opposing surface portion 312 of the first insertion portion 31, preventing it from being engaged with the first insertion portion 31 of the connection box main body 30. As a result, the fixing structure of this embodiment can prevent a fixing member having an anchor portion of an inappropriate length from being erroneously attached to the first insertion portion 31 of the junction box body 30.

[0109] The insertion hole 13b of the first fixing member 10 is configured as an opening extending from the tip surface of the anchor part 12 toward one width direction side YR. The protruding part 313 of the first insertion part 31 extends toward one width direction side YR, and is formed in a cross-sectional shape having a tip that tapers toward one width direction side YR in a cross section along the width direction Y.

[0110] According to this configuration, the fixing structure of this embodiment can easily insert the protrusion portion 313 into the insertion hole 13b even when, for example, the anchor portion 12 of the first fixing member 10 is inserted into the insertion hole 311a of the first insertion portion 31 from a direction inclined with respect to the width direction Y.

[0111] Therefore, the fixing structure of this embodiment can both prevent erroneous assembly of the second fixing member 20 to the first insertion portion 31 of the connection box main body 30 and improve the ease of assembly of the first fixing member 10 to the first insertion portion 31.

[0112] The insertion hole 311a of the first insertion portion 31 is formed in a substantially elongated elliptical shape when viewed from the width direction Y. The protruding portion 313 of the first insertion portion 31 and the insertion hole 13b of the first fixing member 10 are formed in a shape that is long in the major axis direction of the insertion hole 311a.

[0113] According to this configuration, the fixing structure of this embodiment can reliably prevent erroneous assembly of a fixing member having an inappropriate shape, compared to a protrusion and an insertion hole that are substantially circular when viewed from the width direction Y, for example. Specifically, the fixing structure of this embodiment can prevent a fixing member having an insertion hole long in the short axis direction from being attached to the first insertion portion 31 of the connection box body 30 having the protruding portion 313 long in the long axis direction.

[0114] In addition, the anchor portion 12 of the first fixing member 10 is provided with a pair of locking claws 15 arranged opposite each other in the front-rear direction X and engaged with the first insertion portion 31 by expanding in the front-rear direction X in the accommodation space S1. The first insertion portion 31 of the connection box main body 30 is disposed opposite the storage space S1 in the vertical direction, and is provided with a pair of expansion restriction portions 314 that restrict the expansion of the locking claws 25 of the second fixing member 20.

[0115] According to this configuration, the first fixing member 10 having an appropriate shape in which the pair of locking claws 15 face each other in the front-rear direction X can be locked to the first insertion portion 31 of the connection box body 30. On the other hand, the second fixing member 20 cannot be locked to the first insertion portion 31 of the connection box body 30 because the locking claws 25 are prevented from expanding by the expansion restricting portions 314 of the first insertion portion 31 .

[0116] As a result, the fixing structure between the first insertion portion 31 and the first fixing member 10 can more reliably prevent incorrect assembly of the second fixing member 20 by the protrusion portion 313 of the first insertion portion 31 and the expansion restricting portion 314 of the first insertion portion 31, even if an insertion hole is provided in the second fixing member 20.

[0117] In addition, the anchor portion 22 of the second fixing member 20 is provided with a pair of locking claws 25 arranged opposite each other in the width direction Y and which are engaged with the second insertion portion 32 by expanding in the width direction Y in the storage space S1. The second insertion portion 32 of the connection box body 30 is disposed opposite the accommodation space S2 in the vertical direction, and is provided with a pair of expansion restriction portions 323 that restrict the expansion of the locking claws 15 of the first fixing member 10.

[0118] According to this configuration, the second fixing member 20 having an appropriate shape in which the pair of locking claws 25 face each other in the width direction Y can be locked in the second insertion portion 32 of the connection box body 30. On the other hand, the first fixing member 10 cannot be locked to the second insertion portion 32 of the connection box body 30 because the locking claws 15 are prevented from expanding by the expansion restricting portions 323 of the second insertion portion 32 .

[0119] As a result, the fixing structure between the second insertion portion 32 and the second fixing member 20 can reliably prevent erroneous assembly of the first fixing member 10 to the second insertion portion 32 of the connection box main body 30 by the expansion restricting portion 323 of the second insertion portion 32.

[0120] The first fixing member 10 is provided with a substantially belt-shaped band portion 11b that is wound around the outer periphery of the first wire harness 1 to hold the first wire harness 1. According to this configuration, the fixing structure of this embodiment can reduce the increase in the number of parts compared to a configuration in which, for example, the first wire harness 1 is held by a holding member and the holding member is fixed to the first insertion portion 31 of the connection box main body 30 using a fixing member separate from the holding member.

[0121] Furthermore, the fixing structure of this embodiment enables the first fixing member 10 to be attached to the first wire harness 1 in advance, making it easier to attach the first wire harness 1 to the first insertion portion 31 and improving the ease of assembly of the first wire harness 1 to the first insertion portion 31 of the connection box main body 30.

[0122] Furthermore, since the second fixing member 20 has a roughly belt-shaped band portion 21b that holds the second wire harness 2, the fixing structure between the second insertion portion 32 and the second fixing member 20 can achieve the same effect as when the first fixing member 10 has the band portion 11b.

[0123] The electric junction box 3 of this embodiment includes the fixing structure of this embodiment described above and a substantially box-shaped junction box main body 30. The first insertion portion 31 is disposed on an outer surface of the junction box main body 30.

[0124] According to this, the electric junction box 3 can prevent a wire harness different from the desired first wire harness 1 from being assembled to the first insertion portion 31. Therefore, the electric junction box 3 can prevent the wire harness from being restricted to an incorrect wiring route.

[0125] The junction box body 30 has a substantially elliptical insertion hole 311a into which the first fixing member 10 is inserted, and is provided with a first insertion portion 31 in which the first fixing member 10 is engaged. The junction box body 30 is further provided with a second insertion portion 32 that is disposed on an outer surface portion different from the first insertion portion 31, and in which the second fixing member 20 for fixing the second wire harness 2 is engaged via a substantially elliptical insertion hole 321a.

[0126] In addition, the first fixing member 10 is provided with a pair of locking claws 15 that are locked to the first insertion portion 31 by expanding in the minor axis direction of the substantially oblong shape. On the other hand, the second fixing member 20 is provided with a pair of locking claws 25 which are locked to the second insertion portion 32 by expanding in the major axis direction of the substantially oblong shape.

[0127] The first insertion portion 31 is provided with a pair of expansion restriction portions 314 that restrict the expansion of the locking claws in the major axis direction of the substantially oblong shape. On the other hand, the second insertion portion 32 is provided with a pair of expansion restricting portions 323 that restrict the expansion of the locking claws in the minor axis direction of the substantially oblong shape.

[0128] According to this configuration, the electrical junction box 3 can prevent the second fixing member 20 from being assembled to the first insertion portion 31 and the first fixing member 10 from being assembled to the second insertion portion 32. Therefore, even when the electrical junction box 3 is provided with the first insertion portion 31 and the second insertion portion 32, it is possible to prevent erroneous assembly of the first fixing member 10 and the second fixing member 20.

[0129] In the configuration of the present invention and the correspondence with the above-mentioned embodiment, The predetermined member of the present invention corresponds to the first wire harness 1 and the second wire harness 2 of the embodiment, Similarly, The fixing member corresponds to the first fixing member 10, The mounting member corresponds to the junction box body 30, The insertion portion corresponds to the first insertion portion 31, The insertion direction corresponds to the other width direction YL. The deployment direction corresponds to the forward / backward direction X. The orthogonal direction corresponds to the up and down direction, The present invention is not limited to the configurations of the above-described embodiments, and many other embodiments can be obtained.

[0130] For example, in the above-described embodiment, the first fixing member 10 has a band portion 11b and an anchor portion 12, but this is not limited to this, and the fixing member may be a clip with an anchor for fixing the holding member that holds the first wire harness 1 to the first insertion portion 31 of the connection box main body 30.

[0131] In addition, the specified member attached to the connection box main body 30 of the electrical connection box 3 is a wire harness, but this is not limited to this, and any appropriate member may be used as long as it is a member that can be fixed to the electrical connection box 3 using a fixing member. Further, the mounting member to which the fixing member is locked is the electrical junction box 3, but this is not limiting, and the mounting member may be any appropriate member such as the vehicle body or a bracket made of synthetic resin.

[0132] Furthermore, the first wire harness 1 is fixed to the junction box main body 30 using one first fixing member 10, but this is not limiting, and the first wire harness 1 may be fixed to the junction box main body 30 using multiple fixing members. In this case, the multiple fixing members may be either the first fixing member 10 or the second fixing member 20, or a combination of the first fixing member 10 and the second fixing member 20.

[0133] In addition, the hole formed in the anchor shaft 13 of the first fixing member 10 along the width direction Y is defined as the insertion hole 13b, but the present invention is not limited to this, and the insertion hole may be a groove shape recessed in the outer circumferential surface of the anchor shaft 23. In this case, the protruding portion of the first insertion portion 31 is formed into a shape corresponding to the insertion hole of the first fixing member 10.

[0134] Although the insertion hole 311a of the first insertion part 31 and the insertion hole 321a of the second insertion part 32 are formed to have a substantially elliptical shape, they may be substantially circular holes. In this case, the anchor part of the first fixing member 10 and the anchor part of the second fixing member 20 are formed to have shapes corresponding to the insertion hole of the first insertion part and the insertion hole of the second insertion part, respectively.

[0135] In addition, the protrusion 313 of the first insertion portion 31 and the insertion hole 13b of the first fixing member 10 are elongated in the long axis direction of the insertion hole 311a, but this is not limited to this and the protrusion and insertion hole may be elongated in the short axis direction of the insertion hole 311a.

[0136] Even in this case, the fixing structure of this embodiment can reliably prevent erroneous assembly of a fixing member having an inappropriate shape, compared to, for example, a protrusion and an insertion hole that are substantially circular when viewed from the width direction Y. Specifically, the fixing structure can prevent a first fixing member, whose insertion hole is long in the long axis direction, from being attached to a first insertion portion of the connection box body 30, whose protruding portion is long in the short axis direction.

[0137] In addition, the pair of deployment restricting portions 314 in the first insertion portion 31 are shaped to stand up from the seat portion 311 to the opposing surface portion 312, but this is not limited to this and they may be shaped to stand up from the seat portion 311 so that their tips are positioned in the storage space S1. In addition, the pair of deployment restricting portions 323 in the second insertion portion 32 are shaped to stand up from the seat portion 321 to the opposing surface portion 322, but this is not limited to this and the pair may be shaped to stand up from the seat portion 321 so that their tips are positioned in the storage space S2.
