[Technical field]

[0001] The present invention relates to a protector through which an electric wire passes. [Background technology]

[0002] Conventionally, in the field of vehicles, protectors that protect wire harnesses arranged in vehicles and the like by inserting them inside have been widely used. For example, a structure of this type of protector is known in which an option connector provided at a branch line portion of the wire harness is held by a parts mounting structure provided on the protector body (see, for example, Patent Document 1). Patent Document 1 discloses a parts mounting structure that makes it difficult for the option connector to fall off the protector body. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2019-47606 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, this type of connector currently has tolerances in shape (dimensions). In this case, if a connector with a small tolerance is attached to the protector body, they will fit together securely without any gaps and there will be no problem. However, if a connector with the smallest shape within the dimensional tolerance is attached to the protector body, gaps will form between these parts, which will cause rattling. This rattling can also cause abnormal noise.

[0005] An object of the present disclosure is to provide a protector that can suppress rattling between an accessory and a holder. [Means for solving the problem]

[0006] The protector that solves the above problem comprises a protector body through which electric wires are passed, and a holder that holds an accessory part whose use can be set depending on the situation, the holder has a first engagement portion that holds the accessory part by engaging with a second engagement portion provided on the accessory part, and the height of the first engagement portion is formed to be equal to or greater than the height of the second engagement portion. Effect of the Invention

[0007] According to the present disclosure, rattle between the accessory and the holder can be suppressed. [Brief description of the drawings]

[0009] First, the embodiments of the present disclosure will be listed and described. [1] The protector disclosed herein comprises a protector body through which electric wires are passed, and a holder for holding an accessory that can be used or not depending on the situation, the holder having a first engagement portion that holds the accessory by engaging with a second engagement portion provided on the accessory, and the height of the first engagement portion is equal to or greater than the height of the second engagement portion.

[0010] According to the configuration of this example, since the first engagement portion is set higher, even if the gap between the holder and the accessory becomes large due to the dimensional tolerance of the accessory, the accessory can be securely engaged with the holder without any gap between the two engagement portions, thereby making it possible to suppress rattling between the accessory and the holder.

[0011] [2] The tip of the first engaging portion is formed in a flat shape so as to come into surface contact with the accessory. With this configuration, the first engaging portion can be brought into contact with the accessory over a wide area, so that the accessory can be held firmly by the holder. This further contributes to preventing rattling and abnormal noise.

[0012] [3] The holder has an abutment surface that can come into contact with the second engagement portion depending on the size of the accessory. With this configuration, it is possible to make the second engagement portion abut the abutment surface of the holder depending on the size of the accessory. Therefore, when the second engagement portion is brought into contact with the abutment surface of the holder, it is possible to firmly engage the first engagement portion and the second engagement portion, which further contributes to preventing rattling and abnormal noise.

[0013] [4] The first engagement portion has a contact surface at its tip that comes into contact with the accessory when the accessory is held in the holder, and the height of the first engagement portion is the length from the abutment surface to the contact surface. With this configuration, the first engagement portion can be made sufficiently tall, so that the first engagement portion can be securely engaged with the second engagement portion.

[0014] [5] The contact surface is formed in a flat shape so as to come into surface contact with the flat tip of the second engagement part. This configuration allows the second engagement part to come into contact with the holder over a wide area, so that the accessory can be firmly held by the holder. This further contributes to preventing rattling and abnormal noise.

[0015] [6] The holder has an erroneous attachment prevention portion that allows only attachment of the accessory with the correct shape. With this configuration, it is possible to prevent the accessory from being attached to the holder in the wrong direction.

[0016] [7] The holder has a guide portion that allows the accessory to move further inward when the first engagement portion and the second engagement portion come into contact with each other during attachment of the accessory, thereby guiding the attachment of the accessory. With this configuration, the accessory can be smoothly attached to the holder via the guide portion of the holder.

[0017] [Details of the embodiment of the present disclosure] Specific examples of the protector of the present disclosure will be described below with reference to the drawings. Note that the present invention is not limited to these examples, but is indicated by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims. In each drawing, for convenience of explanation, some of the configuration may be shown exaggerated or simplified. Furthermore, the dimensional ratios of each part may differ from the actual ones.

[0018] As shown in FIG. 1, the wire harness 1 includes an electric wire bundle 2 that electrically connects electric equipment (not shown) of a vehicle, and a protector 3 into which the electric wire bundle 2 is inserted. The electric wire bundle 2 includes an electric wire 4 that is a main wire of the electric wire bundle 2, and a branch wire 5 that branches off from the electric wire bundle 2. A portion of the electric wire bundle 2 is inserted inside the protector 3. The protector 3 includes a protector body 6 into which the electric wire bundle 2 (in this example, both the electric wire 4 and the branch wire 5) is inserted. The protector 3 is used, for example, as a protective member for the electric wire bundle 2 or a bypass path for the electric wire bundle 2.

[0019] As shown in Fig. 2, the protector 3 is a housing structure in which an upper case 10 and a lower case 11 are assembled. In this example, the upper case 10 may be composed of either one member or multiple members. The assembly structure of the upper case 10 and the lower case 11 may be, for example, a snap-fit ​​structure in which a claw engages with a mating member. The protector 3 is formed in an elongated shape that is bent midway.

[0020] As shown in Fig. 3, the protector 3 has a plurality of fixing parts 12 as attachment points to the vehicle body (not shown). In this example, the fixing parts 12 are arranged at two locations on the back surface of the protector main body 6 (lower case 11). The fixing parts 12 are preferably, for example, clips that fix the protector 3 to the vehicle body by a hook structure. When a plurality of fixing parts 12 are provided, the fixing parts 12 may be a combination of different structures.

[0021] As shown in Fig. 4, the protector is provided with a holder 16 for holding an accessory 15, the use of which can be set depending on the situation. In this example, the accessory 15 is a connector 17 provided on a branch wire 5 of the electric wire bundle 2. The holder 16 is disposed on a side surface 18 of the protector body 6 (see Fig. 1, etc.). The holder 16 is provided with a recess 19 into which the accessory 15 is inserted for attachment. An opening 19a of the recess 19 is disposed on a first side portion 20 of the holder 16. The first side portion 20 is one of the multiple side surfaces of the holder 16 in the direction in which the protector body 6 extends (the X-axis direction in Fig. 4).

[0022] As shown in FIG. 5, the holder 16 has a first engagement portion 21 that holds the accessory 15 by engaging with a second engagement portion 22 (see FIG. 4, etc.) provided on the accessory 15. In this example, a hole 23 is formed in the upper surface of the holder 16, and the first engagement portion 21 is formed on the back surface of a bridge portion 24 provided on the edge of the hole 23. The first engagement portion 21 is a protrusion 25 formed by protruding a part of the inner surface of the recess 19 of the holder 16, specifically, the back surface of the bridge portion 24. In this example, the first engagement portion 21 is disposed on the upper surface of the recess 19 of the holder 16.

[0023] 4, the second engagement portion 22 is provided at a portion of the portion of the accessory 15 that is inserted into the holder 16. In this example, the accessory 15 is provided with a lever portion 28 that is flexible and deformable with its base as a fulcrum, and the second engagement portion 22 is disposed on the upper surface of the lever portion 28. The lever portion 28 is a portion that is operated when releasing the engagement between the first engagement portion 21 and the second engagement portion 22. When the lever portion 28 is bent by being tilted downward with a finger or the like, the engagement between the first engagement portion 21 and the second engagement portion 22 is released, and the accessory 15 can be removed from the holder 16.

[0024] 6, the tip of the first engagement portion 21 is formed in a flat shape so as to come into surface contact with the accessory 15. Specifically, the first engagement portion 21 has a contact surface 30 at its tip, which comes into contact with the accessory 15 when the accessory 15 is held in the holder 16.

[0025] The holder 16 has an abutment surface 31 that can come into contact with the second engagement portion 22 according to the size R of the accessory 15. The abutment surface 31 is a part of the inner surface of the recess 19 that can come into contact with the protruding second engagement portion 22. The abutment surface 31 is formed in a flat shape so that its tip comes into surface contact with the flat second engagement portion 22.

[0026] The height H1 of the first engagement portion 21 is formed to be equal to or greater than the height H2 of the second engagement portion 22. In this example, the height H1 of the first engagement portion 21 is formed to be greater than the height H2 of the second engagement portion 22. In this example, the height H1 of the first engagement portion 21 is the length from the contact surface 30 to the abutment surface 31.

[0027] Holder 16 has a hole 33 through which a mating connector 32 passes, which is connected to connector 17, which is an accessory 15. Hole 33 is disposed on a second side 34 of holder 16. Second side 34 is the other of the multiple sides of holder 16 in the direction in which protector body 6 extends (X-axis direction in FIG. 4).

[0028] The holder 16 has a guide portion 37 that allows the accessory 15 to move further inward when the first engagement portion 21 and the second engagement portion 22 come into contact during attachment of the accessory 15, thereby guiding the attachment of the accessory 15. In this example, the guide portion 37 is a slope formed on the first engagement portion 21. When the accessory 15 is inserted into the recess 19 of the holder 16, even if the second engagement portion 22 hits the first engagement portion 21, the guide portion 37 of the first engagement portion 21 slides the second engagement portion 22, thereby guiding the accessory 15 to be inserted smoothly.

[0029] As shown in FIG. 7, the holder 16 is provided with an erroneous installation prevention portion 38 that allows the attachment of the accessory 15 only if the shape formed on the accessory 15 is correct. In this example, the erroneous installation prevention portion 38 is a convex portion that protrudes inward from the recess 19 of the holder 16. The erroneous installation prevention portion 38 is formed in a shape corresponding to a reduced-weight portion 39 formed on the accessory 15. The reduced-weight portion 39 is formed in a shape in which a corner of the accessory 15 is cut out. For this reason, when the accessory 15 is inserted into the holder 16, if the vertical orientation of the accessory 15 is not correct, the accessory 15 cannot be inserted into the recess 19 of the holder 16.

[0030] Next, the operation of the protector 3 of this embodiment will be described. 7, accessory 15 attached to the tip of branch wire 5 in electric wire bundle 2 is grasped, and then this accessory 15 is aligned with recess 19 of holder 16. At this time, by checking whether or not the positions of recessed portion 39 provided on accessory 15 and incorrect attachment prevention portion 38 of holder 16 match, the vertical orientation of accessory 15 is adjusted to the correct orientation. Then, accessory 15 is inserted into recess 19 through opening 19a.

[0031] 8, when accessory 15 is inserted into recess 19 of holder 16, second engagement portion 22 comes into contact with first engagement portion 21. In the present example, first engagement portion 21 is formed with inclined guide portion 37, so that even if second engagement portion 22 comes into contact with first engagement portion 21, lever portion 28 bends downward as accessory 15 is inserted, and accessory 15 can be smoothly inserted further in.

[0032] When the accessory 15 is inserted all the way into the recess 19, the first engagement portion 21 and the second engagement portion 22 are engaged with each other (see the two-dot chain line in the figure). This allows the accessory 15 to be firmly attached to the holder 16. This makes it difficult for the accessory 15 to fall off the holder 16.

[0033] 9, when removing the accessory 15 from the holder 16, the tip of the lever portion 28 is pushed with a finger or the like to bend the lever portion 28 downward. This releases the engagement between the first engagement portion 21 and the second engagement portion 22. Therefore, by pulling the accessory 15 toward yourself in this state, the accessory 15 can be smoothly removed from the holder 16.

[0034] Here, as shown in Figures 6, 10, and 11, a shape tolerance may occur in the accessory 15. As an example, the shape tolerance is the size R of the accessory 15 in the height direction. In this example, when the size R of the accessory 15 shown in Figure 6 is "R1", an example is given in which the size R of the accessory 15 shown in Figure 10 is "R2 (>R1)" and the size R of the accessory 15 shown in Figure 11 is "R3 (>R2)".

[0035] In the case of FIG. 6, the size R1 of the accessory 15 is the smallest among the three examples, so when the accessory 15 is attached to the holder 16, the gap U between the accessory 15 and the holder 16 is the "largest". In the case of FIG. 10, the size R of the accessory 15 is the middle among the three examples, so when the accessory 15 is attached to the holder 16, the gap U between the accessory 15 and the holder 16 is the "medium". In the case of FIG. 11, the size R of the accessory 15 is the largest among the three examples, so when the accessory 15 is attached to the holder 16, the gap U between the accessory 15 and the holder 16 is the "smallest". If the accessory 15 has a shape tolerance, for example, when the accessory 15 with a small size R is attached to the holder 16, it will not engage firmly, which will cause rattling and abnormal noise.

[0036] Therefore, in this example, the height H1 of the first engagement portion 21 is set to be equal to or greater than the height H2 of the second engagement portion 22 (H1>H2 in this example). This makes it possible to bring the first engagement portion 21 into contact with the accessory 15 in the mounting state in the "maximum gap" state shown in FIG. 6. Specifically, it becomes possible to bring the contact surface 30 at the tip of the first engagement portion 21 into firm contact with the accessory 15. Therefore, even if the accessory 15 has the smallest size R1 due to the shape tolerance, it becomes possible to firmly fix the accessory 15 to the holder 16. This eliminates the causes of rattling and abnormal noise.

[0037] Also, when the first engagement portion 21 is engaged with the second engagement portion 22 in the "intermediate gap" state shown in FIG. 10 or the "minimum gap" state shown in FIG. 11, the first engagement portion 21 attaches to the accessory 15 by biting into it. In this example, the lever portion 28 is pushed from above by the first engagement portion 21 to bend it, and the first engagement portion 21 and the second engagement portion 22 are engaged. This makes it possible to firmly fix the accessory 15 to the holder 16. Therefore, it is possible to prevent factors that cause rattling or abnormal noise from occurring even in the "intermediate gap" and "minimum gap" states.

[0038] According to the protector 3 of the above embodiment, the following effects can be obtained. (1) The protector 3 includes a protector body 6 through which the electric wire 4 (in this example, the electric wire bundle 2 of the electric wire 4 and the branch wire 5) is passed, and a holder 16 for holding an accessory 15, the use of which can be set depending on the situation. The holder 16 has a first engagement portion 21 for holding the accessory 15 by engaging with a second engagement portion 22 provided on the accessory 15. The height H1 of the first engagement portion 21 is formed to be equal to or greater than the height H2 of the second engagement portion 22.

[0039] According to the configuration of this example, the first engagement portion 21 is set higher, so even if the gap U between the accessory 15 and the holder 16 becomes large due to the dimensional tolerance of the accessory 15, the accessory 15 can be securely engaged with the holder 16 between both engagement portions (the first engagement portion 21 and the second engagement portion 22). This makes it possible to suppress rattling between the accessory 15 and the holder 16. Furthermore, suppressing rattling can also make it difficult for abnormal noise to occur.

[0040] (2) The tip of the first engagement portion 21 is formed in a flat shape so as to come into surface contact with the accessory 15. This configuration allows the first engagement portion 21 to come into contact with the accessory 15 over a wide area, so that the accessory 15 can be firmly held by the holder 16. This further contributes to preventing rattling and abnormal noise.

[0041] (3) The holder 16 has an abutment surface 31 that can come into contact with the second engagement portion 22 in accordance with the size R of the accessory 15. With this configuration, it is possible to make the second engagement portion 22 abut against the abutment surface 31 of the holder 16 in accordance with the size R of the accessory 15. Therefore, when the second engagement portion 22 is brought into contact with the abutment surface 31 of the holder 16, the strength of engagement between the first engagement portion 21 and the second engagement portion 22 is improved, which further contributes to preventing rattling and abnormal noise.

[0042] (4) The first engagement portion 21 has a contact surface 30 at its tip, which comes into contact with the accessory 15 when the accessory 15 is held in the holder 16. The height H1 of the first engagement portion 21 is the length from the abutment surface 31 to the contact surface 30. With this configuration, the height H1 of the first engagement portion 21 can be sufficiently secured, so that the first engagement portion 21 can be securely engaged with the second engagement portion 22.

[0043] (5) The contact surface 31 is formed in a flat shape so as to come into surface contact with the flat tip of the second engagement portion 22. This configuration allows the second engagement portion 22 to come into contact with the holder 16 over a wide area, so that the accessory 15 can be firmly held by the holder 16. This further contributes to preventing rattling and abnormal noise.

[0044] (6) The holder 16 has an incorrect attachment prevention portion 38 that allows attachment of only accessory 15 with the correct shape. With this configuration, when accessory 15 is attached to the holder 16, the orientation of accessory 15 can be prevented from being incorrect.

[0045] (7) Holder 16 has guide portion 37 that allows accessory 15 to move further inward when first engagement portion 21 and second engagement portion 22 come into contact with each other during attachment of accessory 15, thereby guiding attachment of accessory 15. According to this configuration, accessory 15 can be smoothly attached to holder 16 via guide portion 37 of holder 16.

[0046] (8) The holder 16 has a recess 19 into which the accessory 15 is inserted and attached. According to this configuration, an assembled state in which the accessory 15 is inserted and attached inside the holder 16 can be achieved.

[0047] (9) The first engagement portion 21 is a protrusion 25 formed by a part of the inner surface of the recess 19 protruding therefrom. According to this configuration, the accessory 15 can be held in the holder 16 by a simple structure in which the protrusion 25 provided on the holder 16 is hooked onto the accessory 15 to hold it in place.

[0048] (10) Opening 19a of recess 19 is disposed on a side portion (first side portion 20) of holder 16. With this configuration, even if protector 3 is disposed in a location with no space above, accessory 15 can be attached to holder 16 from the side.

[0049] (11) The contact surface 31 is a part of the inner surface of the recess 19 that can come into contact with the protruding second engagement portion 22. With this configuration, even if a load is applied to the accessory 15 attached to the holder 16 in a direction (Z-axis direction in FIG. 6, etc.) intersecting the insertion direction of the accessory 15 (X-axis direction in FIG. 6, etc.), the load can be received locally by a part of the holder 16.

[0050] (12) The holder 16 is disposed on the side surface 18 of the protector body 6. With this configuration, the holder 16 does not protrude upward from the protector body 6, so the protector 3 can be disposed in a location where there is no space above.

[0051] (13) The electric wire 4 is a trunk line of the electric wire bundle 2 passed through the protector body 6. The accessory part 15 is a connector 17 provided on a branch line 5 branched off from the trunk line in the electric wire bundle 2. This configuration makes it possible to securely attach the connector 17 provided on the branch line 5 to the holder 16. Therefore, even if the connector 17 is not required to be used after it is attached to the holder 16 and the state is continued for a long period of time, the connector 17 is unlikely to fall off the holder 16.

[0052] This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that no technical contradiction occurs. 12, the tip of the first engagement portion 21 may be sharp rather than flat. The same is true for the second engagement portion 22.

[0053] 13, the contact surface 31 is not limited to a surface extending in a direction (X-axis direction in the figure) perpendicular to the protruding direction (Z-axis direction in the figure) of the first engagement portion 21, but may be a surface (slope) inclined with respect to the perpendicular direction. Also, the guide portion 37 of the first engagement portion 21 may be omitted.

[0054] As shown in FIG. 14, the first engagement portion 21 is not limited to a shape in which a part of the inner surface of the holder 16 (the bridging portion 24) protrudes, and may be a member constituted by the entire bridging portion 24, for example. 15, the holder 16 may have a structure in which the second engagement portion 22 is sandwiched by a groove portion 41 to hold the accessory 15. In this case, it is preferable that a third engagement portion 42 is further provided inside the holder 16, and the second engagement portion 22 is sandwiched and held by the groove portion 41 that exists between the first engagement portion 21 and the third engagement portion 42.

[0055] The shape of the protector body 6 can be changed to various shapes, such as a straight line shape, an L-shape, or an S-shape. The connector 17, which is the accessory 15, may be shaped so as to omit the lever portion 28. In this case, it is preferable that the connector 17 is formed in a rectangular parallelepiped shape or the like.

[0056] The shape of the first engagement portion 21 may be changed to various shapes as long as it can be engaged with the accessory part 15 . The second engagement portion 22 is not limited to a protrusion, and may be any member having a shape that can engage with the first engagement portion 21.

[0057] The second engagement portion 22 is not limited to being provided on the lever portion 28. For example, the connector 17 may simply be formed in a box shape, and the second engagement portion 22 may be provided on the outer surface of the box. A plurality of holders 16 may be provided on the protector body 6 .

[0058] The opening 19a of the recess 19 of the holder 16 may be located on, for example, the upper or lower surface of the holder 16 instead of on the side surface of the holder 16. The holder 16 does not necessarily have to be provided on the side surface of the protector body 6, but may be disposed on the top or bottom surface of the protector body 6, for example.

[0059] The accessory part 15 is not limited to the connector 17 and may be changed to another part. The protector 3 may be a member through which only the electric wire 4 passes. The location of the protector 3 is not limited to the underside of the floor of the vehicle, but may be anywhere on the vehicle body.

[0060] Each of the electric wire 4 and the branch wire 5 may be made up of a plurality of electric wires, or may be made up of only one electric wire. Although the present disclosure has been described with reference to the embodiment, it is understood that the present disclosure is not limited to the embodiment or structure. The present disclosure also includes various modifications and modifications within the scope of equivalents. In addition, various combinations and forms, as well as other combinations and forms including only one element, more than one element, or less than one element, are also within the scope and concept of the present disclosure.
