[0018] (Description of embodiments of the present invention)

[0019] First, embodiments of the present invention will be described.

[0020] The protector of this invention is as follows.

[0021] (1) A protector for fixing to a fixed object with a screw, the protector comprising: a protector body for holding wiring components; and a screw fastening part protruding from the protector body, the screw fastening part having: a screw insertion part into which a screw is inserted; and an anti-rotation part located away from the center of the screw insertion part, the anti-rotation part contacting the fixed object to restrict the screw fastening part from rotating about the screw.

[0022] According to this protector, the anti-rotation part contacts the fixed object, thereby restricting the rotation of the screw fastening part around the screw. Thus, the rotation of the protector around the screw can be restricted. Furthermore, even using a single screw fastening part can restrict the rotation of the protector, so it is not necessary to fix the protector to the fixed object at multiple points for anti-rotation purposes. This simplifies the shape of the protector.

[0023] (2) In the protector of (1), the screw fastening part may include a fixing piece protruding from the body of the protector, and the anti-rotation part is an anti-rotation protrusion protruding from the fixing piece.

[0024] Therefore, if a recess into which the anti-rotation protrusion is embedded is pre-formed on a fixed object, the anti-rotation function of the protector can be achieved.

[0025] (3) In the protector of (2), the anti-rotation protrusion may also have a cylindrical portion and a partition portion that divides the inner part of the cylindrical portion.

[0026] This reduces the amount of material used for molding the screw fastening parts and achieves a strong result.

[0027] (4) In the protector of (2) or (3), the screw insertion part may be located in the middle of the fixing piece, the fixing piece having a plurality of ribs extending radially around the central axis of the screw insertion part, at least one of the plurality of ribs extending through the anti-rotation protrusion.

[0028] Thus, the screw insertion portion is securely supported in the retaining plate by means of multiple ribs. Furthermore, since at least one of the multiple ribs extends through an anti-rotation protrusion, the anti-rotation protrusion is also securely supported. Therefore, anti-rotation can be performed more reliably by means of the anti-rotation protrusion.

[0029] (5) In any of the protectors in (2) to (4), the anti-rotation protrusion may have a guide surface that tapers towards the end.

[0030] Thus, the anti-rotation protrusion can be easily embedded into the recess of the fixed object through the guide surface.

[0031] (6) In any of the protectors in (2) to (5), the anti-rotation protrusion may be located further away from the protector body than the screw insertion portion.

[0032] In this case, because the anti-rotation protrusion is located further away from the protector body than the screw insertion part, the protector body does not become an obstacle, and the anti-rotation protrusion is easy to identify. Therefore, the anti-rotation protrusion can be easily inserted into the recess of the fixed object to limit rotation.

[0033] (7) In the protector of (6), the screw insertion part may include a screw insertion cylinder part, which is supported by the fixing plate in such a state that at least a portion of it is embedded in the fixing plate, and the maximum width of the anti-rotation protrusion is greater than the minimum distance between the screw insertion cylinder part and the protector body.

[0034] By positioning the anti-rotation protrusion further away from the protector body than the screw insertion portion, the anti-rotation protrusion can be thickened. The maximum width of the anti-rotation protrusion is set to be greater than the minimum distance between the screw insertion sleeve and the protector body, thus enabling more reliable anti-rotation.

[0035] (Details of embodiments of the present invention)

[0036] Specific examples of the protector of the present invention are described below with reference to the accompanying drawings. It should be noted that the present invention is not limited to these examples, but is intended to include all modifications within the meaning and scope equivalent to the claims, as shown by the claims.

[0037] (Implementation Method)

[0038] The protector of the implementation method will be described below. Figure 1 and Figure 2 This is a perspective view of the protector 20. Figure 1 The image shows the object 10 that is fixed to the protector 20. A solid line represents the object 10 to which the protector 20 is fixed, and a double-dotted line represents the object 10 in front of the protector 20. Figure 3This is a top view showing the protector 20. Figure 3 The screw insertion part 44 and the anti-rotation protrusion 46, which can be seen from the bottom side, are indicated by dashed lines. Figure 4 This is a bottom view of the protector 20. Figure 5 This is a side view of the protector 20.

[0039] The protector 20 is fixed to the fixed object 10. The fixed object 10 is, for example, part of the body of a vehicle. For example, a protruding base protruding from the body is the fixed object 10. A threaded hole 11 and an anti-rotation hole 12 are formed in the fixed object 10. The threaded hole 11 and the anti-rotation hole 12 can be either bottomed holes or through holes.

[0040] The protector 20 includes a protector body 30 and a screw fastening and fixing part 40. The protector 20 can also be integrally molded by filling molten resin into a mold.

[0041] The protector body 30 holds the wiring member 18. The wiring member 18 is constructed, for example, by bundling multiple wires together. The wiring member 18 may also be part of a bundle of multiple branched and bundled wires.

[0042] The protector body 30 can also be shaped to accommodate the wiring component 18. For example, the protector body 30 can be formed as a cylinder or a chute. In this embodiment, the protector body 30 is formed as a cylinder.

[0043] The protector body 30 can be formed in a shape that bends midway or in a straight line. In this embodiment, the protector body 30 is formed in a shape that bends midway. The protector body 30 can form a single, unbranched wiring space or a wiring space that branches midway. In this embodiment, the protector body 30 forms a single, unbranched wiring space.

[0044] More specifically, the protector body 30 has a storage section 32 and a cover section 36.

[0045] The storage section 32 has a bottom 33 and a pair of sidewalls 34 and 35. The bottom 33 bends from the middle in the length direction to the width direction. The pair of sidewalls 34 and 35 stand up from the two side edges of the bottom 33. Thus, a storage section 32 with a U-shaped cross-section and bending in the middle is formed.

[0046] The cover 36 is supported by the end edge of one side wall portion 34 via a hinge 34h. The one side wall portion 34 is located on the outside of the curved portion of the protector body 30.

[0047] A locking tab 37p protrudes from the end of the cover portion 36. A receiving portion 34p protrudes from the other side wall portion 35. The other side wall portion 35 is located inside the curved portion of the protector body 30. An anti-detachment protrusion 37pa protrudes outward from the end of the locking tab 37p. A locking hole 34ph is formed in the receiving portion 34p for inserting the locking tab 37p.

[0048] With the cover 36 closed, the opening on the side of the receiving portion 32 opposite to the bottom 33 is closed, and the locking tab 37p is inserted into the locking hole 34ph. In this state, the anti-disengagement protrusion 37pa passes over the locking hole 34ph and is locked to the receiving portion 34p. Thus, the cover 36 remains in the closed state.

[0049] The protector body 30 opens outward at both ends along its length. A wiring member 18 is housed within the protector body 30 at its midpoint along its length, and is thus held along a predetermined path corresponding to the shape of the protector body 30. The wiring member 18 extends outward from the outer openings at both ends of the protector body 30 and is led outward toward the electrical components to which it is connected.

[0050] Alternatively, a wiring fixing piece 30p1 and a wiring pressing piece 30p2 for fixing the wiring member 18 may extend from the end of the protector body 30. The wiring fixing piece 30p1 may also be a part that is bundled together with the wiring member 18 by a binding member such as adhesive tape. The wiring pressing piece 30p2 may also be an elastic piece that presses the wiring member 18 toward the wiring fixing piece 30p1.

[0051] The screw fastening and fixing part 40 protrudes from the protector body 30. The screw fastening and fixing part 40 has a screw insertion part 44 and an anti-rotation protrusion 46 as an anti-rotation part. The screw S is inserted into the screw insertion part 44. The anti-rotation protrusion 46 is located away from the central axis X of the screw insertion part 44.

[0052] The screw fastening part 40 is fixed to the fixed object 10 by inserting the screw S into the screw insertion part 44. Thus, the protector body 30 is fixed to the fixed object 10 without detaching from it. Furthermore, the anti-rotation protrusion 46 contacts the fixed object 10 to restrict the screw fastening part 40 from rotating around the screw S. Therefore, the protector 20 is restricted from rotating around the screw S. That is, the protector 20 is prevented from rotating relative to the fixed object in a constant posture.

[0053] Therefore, by using a screw S to fasten the screw fixing part 40 to the fixed object 10, the protector 20 is fixed to the fixed object 10 in an anti-rotation state.

[0054] (Regarding the screw fastening and fixing part)

[0055] The screw fastening and fixing parts will be explained in more detail.

[0056] The screw fastening and fixing part 40 includes a fixing plate 41. The fixing plate 41 is a plate-shaped portion extending from the other side wall portion 35. The fixing plate 41 may also extend from a portion of the extending direction of the side wall portion 35. In this embodiment, the fixing plate 41 extends from the side wall portion 35 in a portion region centered on the bending part of the protector body 30.

[0057] The orientation of the fixing piece 41 relative to the protector body 30 is arbitrary. In this embodiment, the fixing piece 41 extends along the extended surface of the bottom 33. The two side edges of the base end portion of the fixing piece 41 can also be connected to the side wall portion 35 via the auxiliary plate portion 40a.

[0058] The shape of the fixing piece 41 is arbitrary. In this embodiment, the fixing piece 41 has a shape that gradually narrows from the base end toward the end end. The end portion of the fixing piece 41 has a partially circular plate shape.

[0059] The screw insertion part 44 is located in the middle of the fixing plate 41. The middle position of the fixing plate 41 refers to the inner side of the periphery of the fixing plate 41.

[0060] The screw insertion portion 44 may also include, for example, a screw insertion sleeve portion 45 through which the screw shaft portion Sb of the screw S can pass. The screw insertion sleeve portion 45 may also be a component referred to as a collar. The screw insertion sleeve portion 45 may also be formed of a material harder than the resin forming the retaining plate 41. For example, the screw insertion sleeve portion 45 may also be a metal sleeve.

[0061] The screw is inserted into the cylinder and supported in such a state that at least a portion is embedded in the fixing plate 41.

[0062] For example, a continuous through hole 45h of the same inner diameter is formed inside the screw insertion sleeve 45. The outer periphery of the screw insertion sleeve 45 is formed as an annular flange 45b that extends at one end of a continuous main body 45a of the same outer diameter.

[0063] A mounting hole 41h is formed in the middle of the fixing plate 41, into which the screw insertion sleeve 45 can be inserted. The mounting hole 41h is formed in a shape corresponding to the outer periphery shape of the screw insertion sleeve 45.

[0064] For example, the fixing piece 41 includes a plate portion 42, an annular protrusion 42a, and a rib portion 42b. The plate portion 42 is, for example, a plate-shaped portion of constant thickness. The annular protrusion 42a protrudes from the bottom surface side of the plate portion 42. A mounting hole 41h is formed in the annular protrusion 42a, extending through the thickness direction of the plate portion 42.

[0065] The mounting hole 41h is extended to the size of the flange portion 45b on the side of the fixed object 10, and to the extent that the main body portion 45a can be configured on the side opposite to the fixed object 10, forming a shape with an annular step portion extending towards the bottom in the middle.

[0066] With the flange portion 45b in contact with the aforementioned annular stepped portion, the screw insertion sleeve portion 45 is installed in the aforementioned mounting hole 41h. The screw insertion sleeve portion 45 may also be pressed into the mounting hole 41h, for example. Alternatively, the protector 20, including the fixing plate 41, may be molded with resin using the screw insertion portion 44 as an insert component. In this embodiment, the screw insertion sleeve portion 45 is supported by the fixing plate 41 with its entire outer peripheral surface embedded in it.

[0067] Multiple ribs 42b extend radially around the central axis X of the screw insertion portion 44. That is, the multiple ribs 42b extend radially along an imaginary circle centered on the central axis X.

[0068] It should be noted that a surrounding rib 42c protrudes from the periphery of the plate portion 42, but is not connected to the side wall portion 35. Multiple ribs 42b extend in a manner connected to either the side wall portion 35 or the surrounding rib 42c.

[0069] The anti-rotation protrusion 46 protrudes from the fixing plate 41. The anti-rotation protrusion 46 protrudes more than the plate portion 42, and further protrudes more than the annular protrusion 42a, the rib portion 42b and the surrounding rib portion 42c.

[0070] The anti-rotation protrusion 46 is located away from the central axis X of the screw insertion portion 44. In this embodiment, the anti-rotation protrusion 46 is located further away from the protector body 30 than the screw insertion portion 44. That is, the anti-rotation protrusion 46 is located on the side opposite to the protector body 30 relative to the screw insertion portion 44. Alternatively, the screw insertion portion 44 can be positioned between the anti-rotation protrusion 46 and the protector body 30.

[0071] The position of the anti-rotation protrusion 46 is not limited to the above example and is arbitrary. The anti-rotation protrusion 46 may also be located on the side of the protector body 30 relative to the screw insertion part 44.

[0072] At least one of the plurality of ribs 42b extends via an anti-rotation protrusion 46. For example, the rib 42b extending toward the end portion of the plate portion 42 on the side opposite to the sidewall portion 35 extends via an anti-rotation protrusion 46. In this embodiment, the anti-rotation protrusion 46 is wider than the rib 42b. Therefore, the anti-rotation protrusion 46 protrudes and exposes to both sides of the rib 42b.

[0073] The shape of the anti-rotation protrusion 46 is arbitrary. The shape of the anti-rotation protrusion 46 can be either cylindrical or prismatic. In this embodiment, the shape of the anti-rotation protrusion 46 is cylindrical.

[0074] The thickness of the anti-rotation protrusion 46 is arbitrary. The maximum width W (here, the diameter) of the anti-rotation protrusion 46 can also be greater than the minimum distance D between the screw insertion sleeve 45 and the protector body 30. The anti-rotation protrusion 46 is located further away from the protector body 30 than the screw insertion sleeve 44. Therefore, it is not constrained by the distance between the screw insertion sleeve 45 and the protector body 30, and as a result, the maximum width W of the anti-rotation protrusion 46 can be made greater than the aforementioned minimum distance D.

[0075] The protrusion of the anti-rotation protrusion 46 is only required to ensure that the anti-rotation protrusion 46 can be inserted into the anti-rotation hole 12 when the screw fastening part 40 is in contact with the fixed object 10. For example, the protrusion of the anti-rotation protrusion 46 relative to the rib 42b can be less than 1 / 2 of the maximum width W (diameter) of the anti-rotation protrusion 46. The protrusion can also be more than 1 / 3 of the maximum width W (diameter). This level of protrusion ensures the anti-rotation function while facilitating the insertion of the anti-rotation protrusion 46 into the anti-rotation hole 12.

[0076] The anti-rotation protrusion 46 can be either a hollow portion or a solid portion with an internal filling. In this embodiment, the anti-rotation protrusion 46 has a cylindrical portion 46a and a partition portion 46b. The cylindrical portion 46a protrudes from the plate portion 42. A rib portion 42b extends along the diametrical direction of the cylindrical portion 46a.

[0077] The cylindrical part 46a has an opening on the side of the fixed object 10 and is closed on the opposite side by the plate part 42.

[0078] The partition 46b divides the interior of the cylindrical portion 46a. For example, the partition 46b extends along the diametrical direction in a manner that divides the cylindrical portion 46a into two parts. The partition 46b may also extend in a direction orthogonal to the rib 42b passing through the cylindrical portion 46a.

[0079] By forming the anti-rotation protrusion 46 into a hollow structure as described above, the amount of resin material used to mold the screw fastening part 40 can be reduced. Furthermore, by reducing the wall thickness of the screw fastening part 40, resin shrinkage marks in the screw fastening part 40 can be prevented. Additionally, since the partition 46b passes through the cylindrical part 46a, a robust structure can be achieved while maintaining the hollow nature of the anti-rotation protrusion 46.

[0080] The anti-rotation protrusion 46 may also have a guide surface 46af that gradually tapers towards the end. For example, the end portion of the cylindrical portion 46a may also have a tapered guide surface 46af that gradually narrows towards the end. This makes it easier to insert the anti-rotation protrusion 46 into the anti-rotation hole 12.

[0081] The protector 20 is fixed to the fixing object 10 as follows: The protector 20, which houses the wiring component 18, is prepared within the protector body 30. The screw fastening part 40 is positioned on the fixing object 10 while the anti-rotation protrusion 46 is inserted into the anti-rotation hole 12. At this time, the anti-rotation protrusion 46 is located on the side opposite to the protector body 30 relative to the screw S. Therefore, the anti-rotation protrusion 46 can be easily visually identified from the side opposite to the protector body 30. The insertion of the anti-rotation protrusion 46 is easy because the end position of the anti-rotation protrusion 46 can be confirmed while inserting it into the anti-rotation hole 12.

[0082] The screw S passes through the through hole 45h of the screw insertion part 44 and is threaded into the threaded hole 11. Furthermore, the protector 20 is fixed to the fixed object 10 by clamping the retaining piece 41 between the screw head Sa and the fixed object 10. In this state, the anti-rotation protrusion 46 is inserted into the anti-rotation hole 12, so even if the protector 20 attempts to rotate around the screw S, the rotational torque is accepted by the embedded structure of the anti-rotation protrusion 46 and the anti-rotation hole 12, thereby limiting the rotation of the protector 20.

[0083] (Effects, etc.)

[0084] According to the protector 20 configured as described above, the screw fastening part 40 has a screw insertion part 44 and an anti-rotation protrusion 46 located at a position away from the center of the screw insertion part. The anti-rotation protrusion 46 contacts the fixed object 10 to restrict the screw fastening part 40 from rotating around the screw S. Therefore, the rotation of the protector 20 around the screw S can be restricted. As a result, the path restriction of the wiring member 18 and the position restriction of the protector 20 can be performed with high precision.

[0085] Furthermore, even using a single screw to fasten the fixing part 40 can limit the rotation of the protector 20, so it is not necessary to fix the protector to a fixed object at multiple points for anti-rotation purposes. This simplifies the shape of the protector 20 and reduces costs.

[0086] Alternatively, multiple fixing parts can be omitted from the fixing object 10 side, thereby miniaturizing the fixing area of ​​the fixing object 10.

[0087] Furthermore, since the anti-rotation part is an anti-rotation protrusion 46, the anti-rotation of the protector 20 can be achieved simply by pre-forming an anti-rotation hole 12 into which the anti-rotation protrusion 46 is embedded in the fixing object 10. For example, when the fixing object 10 is a metal component, it is easier to form a concave shape than a convex shape. If the protector 20 is formed of resin or the like, a convex shape can be formed. Therefore, a structure for anti-rotation can be easily realized.

[0088] Furthermore, if the anti-rotation protrusion 46 has a cylindrical portion 46a and a partition portion 46b, the material used for the molding screw fastening portion 40 can be reduced, and resin shrinkage can be suppressed. Additionally, the partition portion 46b allows for a hollow structure while maintaining robustness in the anti-rotation protrusion 46. With a robust anti-rotation protrusion 46, anti-rotation can be performed more reliably.

[0089] Furthermore, because the retaining plate 41 has radially arranged ribs 42b, the screw insertion portion 44 is securely supported within the retaining plate 41. Since at least one of the plurality of ribs 42b extends via the anti-rotation protrusion 46, the anti-rotation protrusion 46 is also securely supported. Therefore, anti-rotation can be achieved more reliably via the anti-rotation protrusion 46.

[0090] In addition, because the anti-rotation protrusion 46 has a guide surface 46af, the anti-rotation protrusion 46 can be easily inserted into the anti-rotation hole 12 through the guide surface 46af.

[0091] Furthermore, because the anti-rotation protrusion 46 is located further away from the protector body 30 than the screw insertion portion 44, the protector body 30 does not become an obstruction, and the anti-rotation protrusion 46 is easily visible. Therefore, the anti-rotation protrusion 46 can be easily inserted into the anti-rotation hole 12 of the fixed object 10 to limit rotation.

[0092] Furthermore, the position and shape of the anti-rotation protrusion 46 can be set while suppressing the influence of the protector body 30. For example, it is easy to move the anti-rotation protrusion 46 away from the screw insertion portion 44. The further away the anti-rotation protrusion 46 is from the screw insertion portion 44, the more effectively it can accept the rotational torque that the protector 20 attempts to rotate.

[0093] Furthermore, for example, the maximum width W of the anti-rotation protrusion 46 can be set to be greater than the minimum distance D between the screw insertion sleeve 45 and the protector body 30. This allows for more reliable anti-rotation.

[0094] (Modified Example)

[0095] It should be noted that in the above embodiment, an example was described where the screw insertion portion 44 is a hole through which the screw S passes. The screw insertion portion can also be a threaded hole for screw engagement. In this case, a screw protruding from the assembled object can also engage with the screw insertion portion, which is a threaded hole.

[0096] Furthermore, in the above embodiment, an example of an anti-rotation protrusion 46 was described. The anti-rotation portion can also be an anti-rotation recess for preventing rotation. The anti-rotation recess can be a bottomed recess or a through hole. In this case, the anti-rotation protrusion protruding from the fixing object 10 can also be inserted into the anti-rotation recess to limit the rotation of the protector.

[0097] It should be noted that the structures described in the above embodiments and variations can be appropriately combined as long as they do not contradict each other.
