  In the wire harness fixture as described above, if the engagement piece is lengthened, the elastically deformable portion can be lengthened when the fixing main body portion is inserted into the mounting hole. Thereby, the insertion force of a fixed main-body part can be made small.

  However, if the engagement piece is lengthened, the length of the fixed main body portion itself increases, and the amount of protrusion of the fixed main body portion increases in a state where the fixed main body portion is attached to the attachment target.

  Then, an object of this invention is to make it possible to make the protrusion amount of a fixing | fixed part as small as possible, making the attachment insertion force of a wire harness fixing tool as small as possible.

In order to solve the above-mentioned problem, the first aspect is a wire harness fixture that is inserted and fixed in an attachment hole formed in the attachment panel, and includes a wire harness attachment portion attached to the wire harness, a pair of side wall portions, A fixed main body portion including a connecting portion for connecting the distal end portions of the pair of side wall portions, and a protrusion projecting in a posture that is inclined outward from a side portion of the connecting portion toward a proximal end portion of the fixed main body portion. A fixing portion including a stop piece, wherein both side portions of the base of the locking piece and the connecting portion are separated via a pair of recesses. In addition, at least one of the pair of recesses is formed in a groove shape that gradually becomes shallower from the inner side to the outer side of the connecting portion with reference to the insertion direction of the fixing portion with respect to the mounting hole.

  A 2nd aspect is a wire harness fixing tool which concerns on a 1st aspect, Comprising: A pair of the said locking piece is provided in the both sides of the said connection part.

An abutting portion is provided that can be in contact with and can sandwich the peripheral edge portion of the mounting hole with the distal end portion of the locking piece.

  A 4th aspect is a wire harness fixing tool which concerns on any one 1st-3rd aspect, Comprising: The inner surface of the said locking piece extends toward the outward of the side part of the said connection part. The inner corner includes a first inner surface and a second inner surface that is connected to the first inner surface via an inner corner portion and is inclined outward toward a proximal end portion of the fixed main body portion. The part is separated from the connecting part via the pair of recesses.

  A 5th aspect is a wire harness fixing tool which concerns on any one 1st-4th aspect, Comprising: The outer surface of the said locking piece extends toward the outward of the side part of the said connection part. The outer corner includes a first outer surface and a second outer surface that is connected to the first outer surface via an outer corner portion and is inclined outward toward a base end portion of the fixed main body portion. The part is separated from the connecting part via the pair of recesses.

It is formed in a groove shape.

  According to the first aspect, since both side portions of the base of the locking piece and the connecting portion are separated via the pair of recesses, when the fixing portion is inserted into the mounting hole, The base portion of a certain locking piece can also be elastically deformed. Thereby, even if it does not enlarge the length of a fixing | fixed part, a latching piece can be elastically deformed largely, and it can make the protrusion amount of a fixing | fixed part as small as possible, making the attachment insertion force of a wire harness fixing tool as small as possible. .

  According to the second aspect, the pair of locking pieces are securely retained and locked by the peripheral edge portion of the mounting hole.

  According to the 3rd aspect, a fixing | fixed part can be firmly fixed with respect to an attachment panel by pinching | interposing the peripheral part of an attachment hole between a contact part and the front-end | tip part of a latching | locking part.

  In addition, when elastically deforming the locking piece inward, it is considered that stress tends to concentrate on the inner corner portion between the first inner surface and the second inner surface. Therefore, by adopting a configuration in which the inner corner portion is separated from the connecting portion via the pair of recesses, the restraining force for a portion where stress is likely to concentrate is reduced, and the locking piece is more easily elastic. Can be deformed.

  In addition, when the locking piece is elastically deformed inward, it is considered that stress is likely to concentrate on the outer corner portion between the first outer surface and the second outer surface. Therefore, by adopting a configuration in which the outer corner portion is separated from the connecting portion via the pair of recesses, the restraining force for a portion where stress is likely to concentrate is reduced, and the locking piece is more easily elasticized. Can be deformed.

It is a schematic perspective view which shows the wire harness fixing tool which concerns on embodiment. It is a bottom view which shows a wire harness fixing tool. It is the III-III sectional view taken on the line of FIG. It is the IV-IV sectional view taken on the line of FIG.

  Hereinafter, the wire harness fixture according to the embodiment will be described. 1 is a schematic perspective view showing a wire harness fixture 20, FIG. 2 is a bottom view showing the wire harness fixture 20, FIG. 3 is a sectional view taken along line III-III in FIG. 2, and FIG. FIG. 4 is a sectional view taken along line IV-IV.

  The wire harness fixture 20 is a member that is inserted into and fixed to the mounting hole 12 formed in the mounting panel 10 (see FIG. 3) while being attached to the wire harness 16 (see FIG. 1).

  The wire harness 16 is a wiring material including at least one electric wire. Usually, the wire harness 16 has a configuration in which a plurality of electric wires are bundled while being branched in a manner corresponding to the arrangement position of various electric devices in the vehicle and the wiring route in the vehicle. Various electric devices mounted on the vehicle are electrically connected to each other via the wire harness 16.

  Further, the mounting panel 10 which is a part of the vehicle body has a mounting hole 12 (here, a long hole), and the wire harness fixture 20 is inserted and fixed in the main mounting hole 12 so that the wire harness 16 is attached and fixed at a fixed position to the attachment panel 10 via the wire harness fixture 20. Thereby, the wire harness 16 is laid along the predetermined wiring path | route in a vehicle body.

  The wire harness fixture 20 includes a wire harness attachment part 22 and a fixing part 30.

  The wire harness attachment part 22 is a part attached to the wire harness 16 (see FIG. 1, omitted in FIGS. 2 to 4). As this wire harness attachment part 22, for example, it is provided with a belt-like part 23 and a square tube part 24 formed at one end of the belt-like part 23, and is spaced on one main surface of the belt-like part 23 along its longitudinal direction. It is possible to assume a structure in which a plurality of protrusions are formed with a gap, and a lock piece that can be locked to the protrusions is formed on the square tube part 24. According to the wire harness mounting portion 22, when the belt-like portion 23 is wound around the wire harness 16 and inserted into the square tube portion 24 and tightened, the lock piece of the square tube portion 24 is attached to any protrusion of the belt-like portion 23. Lock. Thereby, the wire harness attachment part 22 is wound and fixed to the wire harness 16. The wire harness mounting portion 22 has the same configuration as a binding material called a binding band or a cable tie.

  The wire harness attachment part 22 is not limited to the above example as long as it can be attached to the wire harness 16. For example, the wire harness mounting portion is configured to include a simple cylindrical portion, and a binding material called a binding band or a cable tie configured as a separate body from the wire harness mounting portion is inserted through the cylindrical portion. The structure attached and fixed to a wire harness may be sufficient by winding around a wire harness.

  The fixing portion 30 is a portion that is inserted and fixed in the attachment hole 12 of the attachment panel 10, and is integrally formed with the wire harness attachment portion 22 so as to protrude from the wire harness attachment portion 22.

  More specifically, the fixing portion 30 includes a base portion 32, a fixing main body portion 40, and a pair of locking pieces 50.

  The base portion 32 is formed in a plate shape, here, an oval shape. The square tube portion 24 of the wire harness attachment portion 22 is integrally formed on one main surface (the upper surface in FIG. 1) of the base portion 32.

  The outer peripheral portion of the base portion 32 is formed in a shape and size that can close the mounting hole 12. Here, the attachment hole 12 has an oval shape, and the outer peripheral portion of the base portion 32 is formed in an oval shape that is larger (here, one size larger) than the attachment hole 12. Thereby, the outer peripheral part of the base part 32 is comprised as the contact part 33 so that contact | abutting to the peripheral part of the attachment hole 12 from the one main surface side of the attachment panel 10 is carried out.

  In addition, the contact portion 33 which is the outer peripheral portion of the base portion 32 is formed in a shape inclined toward the opposite side of the wire harness attachment portion 22 (that is, the fixed main body portion 40 side) toward the outer peripheral side. It is configured to function as a spring. Thereby, the contact portion 33 can come into contact with the peripheral portion of the mounting hole 12 from the one main surface side of the mounting panel 10 while being elastically deformed.

  However, since the wire harness 16 can be fixed to the mounting panel 10 at a fixed position if the fixing portion 30 can be secured to the mounting hole 12 by the fixing main body portion 40 and the locking piece 50, the contact portion 33 is A configuration that contacts the peripheral edge of the mounting hole 12 is not essential.

  The fixed main body portion 40 includes a pair of side wall portions 42 and a connecting portion 44.

  The pair of side wall portions 42 protrude from the other main surface (the lower surface in FIG. 1) of the base portion 32 with a gap therebetween. Here, a pair of side wall portions 42 protrude from the long axis direction of the oval base 32 with a gap therebetween. The pair of side wall portions 42 are formed in a columnar shape with a semicircular cross section in which the opposing surfaces are flat and the outward surfaces of each other form an arc.

  The connecting portion 44 is formed in a long shape that connects the tip portions of the pair of side wall portions 42. An inward surface of the connecting portion 44 (a surface facing the base portion 32) is formed on a surface parallel to the other main surface of the base portion 32, and a tip-facing surface facing the inward surface of the connecting portion 44 is It is formed on a surface parallel to the other main surface of the base portion 32. Moreover, the outer peripheral surface of the connection part 44 is formed in the shape which inclines inward toward the front end side, ie, the long truncated cone shape which excised the top part of the long cone. As a result, the fixed main body portion 40 can be easily inserted into the mounting hole 12.

  The pair of locking pieces 50 are provided on both sides of the connecting portion 44. If there is one locking piece 50, it can be secured to the mounting hole 12, and therefore it is not essential that a pair of locking pieces 50 be provided.

  The pair of locking pieces 50 are provided at positions that are biased toward either end of the connecting portion 44 so as not to overlap each other in the longitudinal direction of the connecting portion 44. That is, one locking piece 50 is provided in a half region portion on one end portion (left end portion in FIG. 1) side of the connecting portion 44 with respect to one side portion (the front side in FIG. 1) of the connecting portion 44. The other locking piece 50 is located in a half region portion on the other end portion (right end portion in FIG. 1) side of the connecting portion 44 with respect to the other side portion (back side in FIG. 1) of the connecting portion 44. Is provided. When observed from one side opening of the rectangular parallelepiped space surrounded by the base portion 32, the pair of side wall portions 42, and the connecting portion 44, the pair of locking pieces 50 are observed to be shifted in the longitudinal direction of the connecting portion 44 and overlap each other. It is supposed not to. Thereby, when molding the pair of locking pieces 50, by combining and separating the molds from both openings of the rectangular parallelepiped space surrounded by the base 32, the pair of side wall portions 42, and the connecting portion 44, The pair of locking pieces 50 can be molded without using a slide mold or the like.

  Each locking piece 50 is formed in a shape projecting from the side portion of the connecting portion 44 so as to incline outward toward the proximal end side of the fixed main body portion 40. The outward portion of the distal end portion of the locking piece 50 is formed in a shape that bulges outward, and a plurality of (here, three) step portions 51 are provided in the bulged portion. The plurality of step portions 51 are formed in a step shape that is positioned stepwise inside the fixing portion 30 toward the distal end portion of the locking piece 50. As a result, the peripheral edge portion of the mounting hole 12 is locked in a stepwise manner from the proximal-side step portion 51 of the locking piece 50 toward the distal-end step portion 51, and is unlikely to return in the reverse direction. It has become. In addition, the position of the step 51 on the most distal end side of the locking piece 50 is a gap between the step 51 and the contact portion 33 and the thickness of the mounting panel 10 or smaller (slightly smaller) than this. Is set to be provided. As a result, in the state where the step 51 on the most distal end side of the locking piece 50 is locked to the peripheral edge portion of the mounting hole 12 from the other main surface side of the mounting panel 10, the front end portion of the locking piece 50 and the contact portion 33 The peripheral edge of the mounting hole 12 is sandwiched between the two.

  An extending piece 54 extending toward the inside is formed on the inner surface of the locking piece 50. The extension piece 54 abuts on the inner surface of the connecting portion 44 when the locking piece 50 falls inward, and serves to prevent the locking piece 50 from falling inward.

  In addition, a pair of recesses 46 and 48 are formed between both side portions of the base of the locking piece 50 and the connecting portion 44, and both sides of the base of the locking piece 50 and the connecting portion 44 are connected to the pair. The recesses 46 and 48 are separated.

  At least one of the pair of recesses 46, 48, here, the recess 46 from the center of the connecting portion 44 of the pair of recesses 46, 48 is directed from the inside to the outside of the connecting portion 44 (in other words, fixed). It is formed in a groove shape that gradually becomes shallower (in the direction of insertion of the portion 30) (see FIG. 3). As a result, for each of the outward portion and the inner portion of the locking piece 50, a sufficiently large elastically deformable portion in the extending direction of the locking piece 50 is secured. Further, as described above, since the recess 46 is formed in a groove shape that gradually becomes shallower from the inside to the outside of the connecting portion 44, sufficient strength is ensured in the central portion of the connecting portion 44. The concave portion 48 may also be formed in the same groove shape.

  Further, the concave portion 48 from the end portion of the connecting portion 44 of the pair of concave portions extends straight from the inner side to the outer side of the connecting portion 44 (in other words, along the insertion direction of the fixing portion 30). It is formed in a groove shape having a bottom. Thereby, on the concave portion 48 side, the base portion of the locking piece 50 by the connecting portion 44 is reduced as much as possible.

  The depths of the concave portions 46 and 48 on the inward surface of the connecting portion 44 are the same, and the concave portion 46 is formed in a groove shape that gradually becomes shallower from the inside to the outside of the connecting portion 44. The overall depth (for example, the average depth) is less than the depth of the recess 48. For this reason, sufficient strength is secured at the central portion of the connecting portion 44 that is easily elastically deformed.

  Here, of the pair of recesses 46, 48 provided at the base of each locking piece 50, the recess 46 from the center of the connecting portion 44 is provided at the same position in the longitudinal direction of the connecting portion 44. . For this reason, in the center part in which the recessed part 46 was formed in both sides among the connection parts 44, the width | variety of the inward part is smaller than the width | variety of the outward part. However, it is not essential that the positions of the concave portions 46 on both sides of the connecting portion 44 are provided at the same position in the longitudinal direction of the connecting portion 44.

  Further, the inner surface 52 of the locking piece 50 has a shape in which a first inner surface 52a and a second inner surface 52b are connected via an inner corner portion 52c (see FIG. 3). The first inner surface 52a has a shape extending outward from the side of the connecting portion 44, more specifically, a shape extending outward from the inward surface of the connecting portion 44 in a flush manner. Is formed. The second inner surface 52b is formed in a shape extending so as to incline outward from the end portion of the first inner surface 52a toward the proximal end portion of the fixed main body portion 40 through an inner corner portion 52c forming an obtuse angle. ing. The inner corner portion 52 c is separated from the connecting portion 44 through a pair of concave portions 46 and 48. In other words, the pair of concave portions 46 and 48 are formed in a shape that is recessed inwardly of the inner corner portion 52c. Therefore, the locking piece 50 can be elastically deformed relatively freely without being constrained by the connecting portion 44 at the inner corner portion 52c.

  Further, the outer surface 53 of the locking piece 50 has a shape in which a first outer surface 53a and a second outer surface 53b are connected via an outer corner portion 53c (see FIG. 3). The first outer surface 53a has a shape extending outward from the side portion of the connecting portion 44, more specifically, a shape extending outward from the outward surface of the connecting portion 44 in a flush manner. Is formed. The second outer surface 53b is formed in a shape extending from the end portion of the first outer surface 53a so as to incline outward toward the base end portion of the fixed main body portion 40 through an outer corner portion 53c having an obtuse angle. ing. A bulging portion in which the step 51 is formed is formed at the end of the second outer surface 53b. Further, the outer corner portion 53 c is separated from the connecting portion 44 through a pair of concave portions 46 and 48. In other words, the pair of recesses 46 and 48 are formed in a shape that is recessed inward from the outer corner portion 53c. For this reason, the locking piece 50 can be elastically deformed relatively freely without being restrained by the connecting portion 44 at the outer corner portion 53c.

  The wire harness fixture 20 thus configured is inserted and fixed in the mounting hole 12 of the mounting panel 10 as follows. That is, the fixing portion 30 is inserted into the attachment hole 12 in a state where the wire harness 16 is attached to the wire harness attachment portion 22. Then, the outer surface 53 and the bulging portion of the pair of locking pieces 50 come into contact with the peripheral edge of the mounting hole 12, and the pair of locking pieces 50 are elastically deformed inward. At this time, since the base end portions of the pair of locking pieces 50 are separated from the connecting portion 44 via the pair of recesses 46 and 48, the configuration in which such a pair of recesses 46 and 48 are not formed is provided. The elastically deformable portion of each locking piece 50 can be enlarged in the longitudinal direction of the locking piece 50. For this reason, each locking piece 50 can be elastically deformed easily including the base portion. When the peripheral edge portion of the mounting hole 12 reaches each step portion 51 and sequentially gets over the plurality of step portions 51, the locking piece 50 is deformed toward the original shape, that is, outward. When the peripheral edge of the mounting hole 12 reaches the stepped portion 51 at the most distal end of the locking piece 50, the contact portion 33 elastically contacts the peripheral edge of the mounting hole 12. As a result, the mounting panel 10 is sandwiched between the contact portion 33 and the stepped portion 51 of the locking piece 50 at the peripheral edge of the mounting hole 12, and the wire harness fixture 20 is fixedly attached to the mounting panel 10. .

  According to the wire harness fixture 20 configured as described above, since the both side portions of the base of the locking piece 50 and the connecting portion 44 are separated via the pair of recesses 46 and 48, the fixing portion 30 is attached. When inserted into the hole 12, the base portion of the locking piece 50 between the pair of recesses 46 and 48 can be easily elastically deformed. Thereby, even if it does not enlarge the length of the fixing | fixed part 30, the latching piece 50 can be largely elastically deformed, and the protrusion amount of the fixing | fixed part 30 is made possible, making the attachment insertion force of the wire harness fixing tool 20 as small as possible. Can be made as small as possible.

  Further, as described above, the elastically deformable portion of the locking piece 50 in the longitudinal direction of the locking piece 50 can be lengthened to reduce the insertion force. As a result, the thickness of the locking piece 50 is increased. This also makes it possible to improve the holding force of the fixing portion 30.

  In addition, since the pair of locking pieces 50 are provided on both side portions of the connecting portion 44, the fixing portion 30 can be more securely retained from the mounting hole 12.

  At this time, the pair of locking pieces 50 are provided at positions offset to either end of the connecting portion so as not to overlap each other in the longitudinal direction of the connecting portion 44. When molding the mold, by combining and separating the molds from both openings of the rectangular parallelepiped space surrounded by the base 32, the pair of side wall parts 42 and the connecting part 44, without using a slide mold or the like, The outward face and the inward face of the pair of locking pieces 50 can be easily molded.

  Further, since the peripheral edge portion of the mounting hole 12 is sandwiched between the contact portion 33 and the locking piece 50, the fixing portion 30 can be more firmly fixed to the mounting panel 10.

  Moreover, since the recessed part 46 is formed in the groove | channel shape which becomes shallow gradually toward the outer side from the inner side of the connection part 44, the recessed part to the connection part 44 is enlarged, enlarging the part which can be elastically deformed of the latching piece 50. FIG. By reducing the shape as much as possible, the strength of the connecting portion can be improved.

  In particular, of the pair of recesses 46 and 48, the recess 46 from the center of the connecting portion 44 is formed in a groove shape that gradually becomes shallower from the inner side to the outer side of the connecting portion 44, and Since it is formed in a shape shallower than the concave portion 48, the elastic deformation of the locking piece 50 is ensured, and the elastic deformation of the central portion of the connecting portion 44 is suppressed to prevent the fixing portion 30 from coming off. Can do.

  That is, when a force in the pulling direction acts on the wire harness fixture 20 with the fixing portion 30 inserted and fixed in the mounting hole 12, the force is received by the connecting portion 44 via the locking piece 50. . When the force acts on the connecting portion 44, the connecting portion 44 bends like a bow with the connecting portions to the side wall portions at both ends as fixed portions. At this time, if the central portion of the connecting portion 44 is weak in strength, it will be bent in a V shape, making it difficult to sufficiently receive the force. Therefore, the concave portion 46 from the center of the connecting portion 44 of the pair of concave portions 46 and 48 is formed in a groove shape that gradually becomes shallower from the inner side to the outer side of the connecting portion 44, and from the end portion of the connecting portion 44. By forming it in a shape shallower than the concave portion 48, the strength in the central portion of the connecting portion 44 is ensured, so that the force in the removal direction can be sufficiently received. Thereby, it is possible to prevent the fixing part 30 from coming off. In addition, since the edge part of the connection part 44 is a location connected with the side wall part 42, even if the depth of the recessed part 48 is somewhat large, even if it receives the force of the said removal direction, it is hard to bend greatly. For this reason, the recessed portion 48 from the end of the connecting portion 44 has a deeper shape than the recessed portion 46 from the viewpoint of reducing the restraining force on the base of the locking piece 50 as much as possible.

  Further, since the inner corner portion 52c of the locking piece 50 is separated from the connecting portion 44 via the pair of recesses 46 and 48, the locking piece 50 can be elastically deformed more easily. That is, when the locking piece 50 is elastically deformed inward, it is considered that stress is likely to concentrate on the inner corner portion 52c. Therefore, if the inner corner portion 52c is separated from the connecting portion 44 via the pair of concave portions 46, 48, the restraining force for the portion where the stress tends to concentrate can be reduced, and the locking piece 50 can be It can be easily elastically deformed. Thereby, the insertion force of the fixing | fixed part 30 can be reduced.

  Further, since the outer corner portion 53c of the locking piece 50 is also separated from the connecting portion 44 via the pair of concave portions 46 and 48, the locking piece 50 can be elastically deformed more easily from this point. it can. That is, it is considered that when the locking piece 50 is elastic inward, stress is likely to be concentrated on the outer corner portion 53c. Therefore, if the outer corner portion 53c is separated from the connecting portion 44 via the pair of concave portions 46, 48, the restraining force for the portion where the stress is likely to concentrate can be reduced, and the locking piece 50 can be It can be easily elastically deformed. Also by this, the insertion force of the fixing portion 30 can be reduced.

  As described above, the present invention has been described in detail. However, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
