This application is based on and claims priority from Japanese Patent Application No. 2020-041734, filed on Mar. 11, 2020, with the Japan Patent Office, the disclosure of which is incorporated herein in their entireties by reference.
The present disclosure relates to a wire guide device.
A cable guide device (referred to as a “wire guide device” hereinafter) disclosed in Japanese Patent Laid-open Publication No. 2007-174735 is to be arranged at an end portion of a cable guide, and a wire is passed through the inside thereof. This wire guide device includes two divided members (referred to as “divided parts” hereinafter) that can be divided along division faces, and a spherical held portion to be rotatably coupled to the inner sides of the divided parts. The held portion is provided with a first opening that is open toward the cable guide, and includes two coupling pieces that protrude toward the cable guide from the two ends in the vertical direction of the first opening. A link part of the cable guide is rotatably coupled to the coupling pieces. The technologies related to this type of wire guide device are also disclosed in Japanese Patent Laid-open Publication Nos. 2016-135638, 2015-154520 and 2016-082693.
In the case of Japanese Patent Laid-open Publication No. 2007-174735, there is a concern that, when the cable guide is bent by a large amount or a foreign object (including a foot or the like) interferes with an end portion of the cable guide or the wire guide device, the positions of the division faces of the divided parts will shift, and the divided parts will undergo torsional deformation. If the divided parts undergo torsional deformation, there is a risk that locks for holding the divided parts will be released, and thus the wire guide device will come loose from the cable guide.
Accordingly, it is an object of the present disclosure to provide a wire guide device that is configured such that the divided parts can be favorably kept in a combined state.
A wire guide device of the present disclosure is a wire guide device that is to be arranged at an end portion of a cable guide and is internally provided with an insertion hole through which a wire is passed, the wire guide device comprising a first divided part and a second divided part that can be combined in a width direction that intersects a direction in which the insertion hole is formed, wherein the first divide part and the second divided part include locking portions that are locked to each other in the combined state, division faces that are opposed to each other in the width direction, and restriction portions that are provided separately from the locking portions and abut against each other to restrict positional shift of the division faces.
With the present disclosure, it is possible to provide a wire guide device that is configured such that the divided parts can be favorably kept in a combined state.
The foregoing summary is illustrative only and is not intended to be in any way limiting. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features will become apparent by reference to the drawings and the following detailed description.
In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here.
First, embodiments of the present disclosure will be listed and described.
(1) A wire guide device of the present disclosure is a wire guide device that is to be arranged at an end portion of a cable guide and is internally provided with an insertion hole through which a wire is passed, the wire guide device comprising a first divided part and a second divided part that can be combined in a width direction that intersects a direction in which the insertion hole is formed, wherein the first divide part and the second divided part include locking portions that are locked to each other in the combined state, division faces that are opposed to each other in the width direction, and restriction portions that are provided separately from the locking portions and abut against each other to restrict positional shift of the division faces.
With the above-mentioned configuration, the positional shift of the division faces of the first divided part and the second divided part is restricted by the restriction portions even when an external force is applied to the first divided part and the second divided part in the combined state, and therefore, the first divided part and the second divided part are stably kept in the combined state.
It should be noted that the concept of the restriction portions in the above-described configuration includes at least one of a vertical movement restriction portion (such as a lateral piece and an opposed wall (which abut against each other) and a first rear-side restriction portion and a second rear-side restriction portion (which abut against each other) shown as examples in Embodiment 1) (which will be described later) and a slide restriction portion (such as a vertical piece and an opposed wall (which abut against each other) shown as examples in Embodiment 1) (which will be described later).
(2) It is preferable that the restriction portions include vertical movement restriction portions that are provided on the first divided part and the second divided part and abut against each other in a vertical direction intersecting the width direction and a direction in which the insertion hole is formed.
With the above-mentioned configuration, the vertical movement restriction portions can prevent the vertical positional shift of the first divided part and the second divided part.
(3) It is preferable that an upper wall that covers an upper side of the insertion hole and a lower wall that covers a lower side of the insertion hole are provided to the first divided part and the second divided part, and the vertical movement restriction portions are provided on the upper walls and/or the lower walls.
With the above-mentioned configuration, the vertical movement restriction portions can be provided along the wall surfaces of the upper walls and/or the lower walls, and therefore, a broad area can be secured for forming the vertical movement restriction portions, thus making it possible to reliably prevent the vertical positional shift of the first divided part and the second divided part.
(4) It is preferable that one end of the insertion hole is open toward the cable guide, the first divided part and the second divided part include end walls for closing an end portion of the insertion hole opposite to the one end, and the vertical movement restriction portions are provided on the end walls.
With the above-mentioned configuration, the vertical movement restriction portions can be provided at positions spaced apart from the cable guide, and therefore, it is possible to keep a foreign object from coming into contact with the vertical movement restriction portions provided on the end walls when the foreign object interferes with a portion close to the cable guide. As a result, the first divided part and the second divided part can be reliably kept in the state in which the vertical movement restriction portions provided on the end walls are abutted against each other.
(5) It is preferable that an upper wall that covers an upper side of the insertion hole and a lower wall that covers a lower side of the insertion hole are provided to the first divided part and the second divided part, and the restriction portions include slide restriction portions that are provided to the first divided part and the second divided part and abut against each other in a direction extending along wall surfaces of the upper walls and/or the lower walls.
With the above-mentioned configuration, the slide restriction portions can prevent the positional shift of the first divided part and the second divided part in the sliding direction (a direction extending along the wall surfaces of the upper walls and/or the lower walls).
(6) It is preferable that the restriction portions include vertical movement restriction portions that are provided on the first divided part and the second divided part and abut against each other in a vertical direction intersecting the width direction and a direction in which the insertion hole is formed, and the vertical movement restriction portions and the slide restriction portions are provided on the upper walls and/or the lower walls so as to intersect each other.
With the above-mentioned configuration, the vertical movement restriction portions and the slide restriction portions can be provided together so as to occupy a small area on the upper walls and/or the lower walls, which can contribute to a reduction in size of the wire guide device.
(7) It is preferable that the vertical movement restriction portions include: a lateral piece provided on the first divided part; and a lateral groove that is provided on the second divided part and into which the lateral piece is fitted, and the slide restriction portions include: a vertical piece that is provided on the first divided part and intersects the lateral piece; and a vertical groove that is provided on the second divided part and intersects the lateral groove and into which the vertical piece is fitted.
With the above-mentioned configuration, the vertical movement restriction portions and the slide restriction portions having simple structures can be easily formed on at least one of the upper wall and the lower wall.
It is preferable that the vertical piece is provided on at least one of the upper wall and the lower wall of the first divided part and has a rib-like shape extending in the width direction, the vertical groove is provided on at least one of the upper wall and the lower wall of the second divided part, extends in the width direction, and is open in the parting face, and the vertical groove includes an introduction portion whose diameter increases toward an open end.
With the above-mentioned configuration, the vertical piece is introduced into the introduction portion and fitted into the vertical groove, thus making it possible to smoothly perform the operation for combining the first divided part and the second divided part.
Hereinafter, specific embodiments of a wire guide device of the present disclosure will be described with reference to the drawings. It should be noted that the present invention is not limited to these embodiments and is defined by the scope of the appended claims, and all changes that fall within the same essential spirit as the scope of the claims are intended to be included therein.

The front-end portion of the first divided part 20 is provided with the two coupling portions 31 described above. The coupling portions 31 are provided on the first upper wall portion 11 and the first lower wall portion 13. At the rear-end portion of the first divided part 20, the divided part of the rotating portion 23 is provided on one of two sides in the width direction with an axis passing through the centers of the coupling portions 31 in the width direction being at the center of the two sides, and a space is formed in a notch-like shape on the other side. As shown in
The first divided part 20 includes inner plate portions 37 at positions on the first upper wall portion 11 and the first lower wall portion 13 that are adjacent to the lateral pieces 36a and 36b in the width direction. Step portions 38 extending in the front-rear direction are formed between the inner plate portions 37 and the lateral pieces 36a and 36b, respectively. The step portions 38 are formed on the inner and outer surfaces of the first upper wall portion 11 and the first lower wall portion 13, respectively. The inner plate portions 37 are located at positions inward from the lateral pieces 36a and 36b and the flat plate portions 32 via the step portions 38, by an amount that corresponds to the step portions 38.
The first divided part 20 includes vertical pieces 39a and 39b extending in the width direction that are provided on the inner and outer surfaces of the lateral pieces 36a and 36b in the first upper wall portion 11 and the first lower wall portion 13. The vertical piece 39a is provided on the first upper wall portion 11. The vertical piece 39b is provided on the first lower wall portion 13. The outer vertical pieces 39a and 39b have a rib-like shape that are elongated in the width direction from the lateral pieces 36a and 36b to the inner plate portions 37. As shown in
The lateral piece 36a of the first upper wall portion 11 serves as a portion of upper guide portions 36a, 39a and 46a and a portion of vertical movement restriction portions 36a, 36b, 45, 46a, 46b, and 54. The lateral piece 36b of the first lower wall portion 13 serves as a portion of lower guide portions 36b, 39b and 46b and a portion of the vertical movement restriction portions 36a, 36b, 45, 46a, 46b, and 54. The vertical piece 39a of the first upper wall portion 11 serves as a portion of the upper guide portions 36a, 39a, and 46a and a portion of slide restriction portions 39a, 39b, 46a, and 46b. The vertical piece 39b of the first lower wall portion 13 serves as a portion of the lower guide portions 36b, 39b, and 46b and a portion of the slide restriction portions 39a, 39b, 46a, and 46b. The upper guide portions 36a, 39a, and 46a guide the combining operations of the first divided part 20 and the second divided part 30 on the upper side of the wire guide device 10. The lower guide portions 36b, 39b, and 46b guide the combining operations of the first divided part 20 and the second divided part 30 on the lower side of the wire guide device 10. The vertical movement restriction portions 36a, 36b, 45, 46a, 46b, and 54 restrict the positional shift of the first divided part 20 and the second divided part 30 in the vertical direction while they are combined. The slide restriction portions 39a, 39b, 46a, and 46b restrict the positional shift of the first divided part 20 and the second divided part 30 in the front-rear direction while they are combined.
As shown in
The first divided part 20 includes two first rear-side restriction portions 45 that are provided at positions close to the two ends in the vertical direction of the rear-end outer surface of the first end wall portion 17. As shown in
The second divided part 30 does not include the coupling portions 31 described above. As shown in
As shown in
The second divided part 30 includes lateral grooves 47 that are open in the division faces 35 and are respectively located between the opposed walls 46a and between the opposed walls 46b in the second upper wall portion 12 and the second lower wall portion 14. The lateral grooves 47 are slit grooves extending in the front-rear direction and are open forward, and the rear ends thereof are closed by the divided part of the rotating portion 23.
The second divided part 30 includes vertical grooves 48 that pass through the opposed walls 46a and 46b in the vertical direction (thickness direction) in the second upper wall portion 12 and the second lower wall portion 14. The vertical groove 48 and the lateral groove 47 intersect at a right angle and are in communication with each other. The vertical grooves 48 extend in the width direction in the opposed walls 46a and 46b, and are open in the division faces 35. The vertical grooves 48 include introduction portions 55 whose widths increase toward the open ends. The introduction portions 55 expand in a curved shape (funnel shape) toward the division faces 35. The opposed walls 46a of the second upper wall portion 12 serve as portions of the upper guide portions 36a, 39a, and 46a and portions of the vertical movement restriction portions 36a, 36b, 45, 46a, 46b, and 54. The opposed walls 46b of the second lower wall portion 14 serve as portions of the upper guide portions 36b, 39b, and 46b and portions of the vertical movement restriction portions 36a, 36b, 45, 46a, 46b, and 54.
The second divided part 30 includes front-side locking pieces 49 that are provided on the front portions of the outer opposed walls 46a and 46b in the second upper wall portion 12 and the second lower wall portion 14. As shown in
As shown in
The rear-side locking piece 51, the rear-side locking protrusion 42, the front-side locking pieces 49, and the front-side locking protrusions 41 together serve as locking portions 41, 42, 49, and 51 for keeping the first divided part 20 and the second divided part 30 in the combined state.
The second divided part 30 includes two second rear-side restriction portions 54 that are provided at positions close to the two ends in the vertical direction of the rear-end outer surface of the second end wall portion 18. As shown in
As shown in
The following will describe an example of an operation for assembling the wire harness 100, and the functions of the wire guide device 10.
In the state in which the first divided part 20 and the second divided part 30 are separated from each other, the wires 110 extending from the inside of the cable guide 120 are placed along the inner surface side of the first side wall portion 15 of the first divided part 20. In the first divided part 20, the wires 110 are arranged extending from the front-side opening 21 of the first divided part 20 to the upper-side opening 22 thereof. Furthermore, the wires 110 are drawn upward through the upper-side opening 22.
The wires 110 are placed along the first divided part 20, and the link part 121 located at an end portion of the cable guide 120 is coupled to the coupling portions 31 of the first divided part 20. As a result, the first divided part 20 is held at an end portion of the cable guide 120 before the first divided part 20 and the second divided part 30 are combined.
Subsequently, the second divided part 30 is combined with the first divided part 20 laterally (in the width direction). In the process of combining the first divided part 20 and the second divided part 30, the first upper wall portion 11 and the second upper wall portion 12 overlap each other in the vertical direction, and the first lower wall portion 13 and the second lower wall portion 14 overlap each other in the vertical direction (see
In the process of combining the first divided part 20 and the second divided part 30, the front-side locking pieces 49 come into contact with the front-side locking protrusions 41 and undergo outward flexural deformation, and the rear-side locking piece 51 comes into contact with the rear-side locking protrusion 42 and undergoes outward flexural deformation. When the first divided part 20 and the second divided part 30 reach the positions where their division faces 34 and 35 come into contact, the front-side locking pieces 49 and the rear-side locking piece 51 are elastically restored, and the front-side locking protrusions 41 and the rear-side locking protrusion 42 are fitted into the front-side locking pieces 49 and the rear-side locking piece 51. As a result, the first divided part 20 and the second divided part 30 are kept in a combined state.
In the state in which the first divided part 20 and the second divided part 30 are combined, the vertical pieces 39a and 39b are entirely accommodated in the vertical grooves 48, and the end surfaces of the vertical pieces 39a and 39b are flush with the inner and outer surfaces of the opposed walls 46a and 46b. The division faces 35 of the inner opposed walls 46a and 46b are opposed to the step portions 38, and the inner surfaces of the inner opposed walls 46a and 46b are flush with the inner surfaces of the inner plate portions 37. Accordingly, the inner surfaces of the first divided part 20 are continuous with the inner surfaces of the second divided part 30, and no steps are formed. As a result, it is possible to prevent the wires 110 inserted through the insertion hole 19 from being damaged due to interference with the steps.
When the cable guide 120 is bent or an external force is applied to the cable guide 120 from above due to the sliding door 90 being opened or closed in the state in which the first divided part 20 and the second divided part 30 are combined, torsional force is generated between the cable guide 120 and the wire guide device 10. If the torsional force is excessively large, there is a concern that the positions of the division faces 34 and 35 will shift, and locking between the front-side locking pieces 49 and the front-side locking protrusions 41 and locking between the rear-side locking piece 51 and the rear-side locking protrusion 42 will be released, and thus the first divided part 20 and the second divided part 30 will be separated from each other.
In that respect, in the case of Embodiment 1, the first rear-side restriction portions 45 and the second rear-side restriction portion 54 are fitted to each other in a recess-projection manner and are engaged with each other in the vertical direction, and in addition, the lateral pieces 36a and 36b abut against the opposed walls 46a and 46b in the vertical direction in the lateral grooves 47 (see
As described above, with Embodiment 1, the restriction portions 36a, 36b, 39a, 39b, 45, 46a, 46b, and 54, which are provided separately from the locking portions 41, 42, 49 and 51 and include the vertical movement restriction portions 36a, 36b, 45, 46a, 46b, and 54 and the slide restriction portions 39a, 39b, 46a, and 46b, restrict the positional shift of the division faces 34 and 35 of the first divided part 20 and the second divided part 30 even when an external force such as torsional force is applied to the first divided part 20 and the second divided part 30 in the combined state. Accordingly, the first divided part 20 and the second divided part 30 are stably kept in the combined state.
Since the vertical movement restriction portions 36a, 36b, 46a, and 46b are provided along the wall surfaces of the upper walls 11 and 12 and the lower walls 13 and 14, the sizes of the lateral grooves 47, the lateral pieces 36a and 36b, and the like in the front-rear direction can be increased, thus making it possible to reliably prevent positional shift of the first divided part 20 and the second divided part 30 in the vertical direction.
Since the vertical movement restriction portions 45 and 54 are also provided on the end walls 17 and 18, it is possible to keep a foreign object (including a foot or the like) from coming into contact with the vertical movement restriction portions 45 and 54 when an external force caused by interference by a foreign object is applied to the cable guide 120 side.
Moreover, the vertical movement restriction portions 36a, 36b, 46a, and 46b and the slide restriction portions 39a, 39b, 46a, and 46b intersect and thus occupy small areas on the upper walls 11 and 12 and the lower walls 13 and 14, which can contribute to the reduction in the size of the wire guide device 10. In particular, the vertical movement restriction portions 36a, 36b, 46a, and 46b include the lateral pieces 36a and 36b provided on the first divided part 20, and the lateral grooves 47 that are provided on the second divided part 30 and to which the lateral pieces 36a and 36b are to be fitted, and the slide restriction portions 39a, 39b, 46a, and 46b include the vertical pieces 39a and 39b that are provided on the first divided part 20 and intersect the lateral pieces 36a and 36b, and the vertical grooves 48 that are provided in the second divided part 30 and intersect the lateral grooves 47 and to which the vertical pieces 39a and 39b are fitted, and therefore, the vertical movement restriction portions 36a, 36b, 46a, and 46b and the slide restriction portions 39a, 39b, 46a, and 46b do not have complicated structures.
In the case of Embodiment 1, the front-side locking pieces 49 (portions of the locking portion) are located at positions on the second upper wall portion 12 and the second lower wall portion 14 that are farther away from the rotating portion 23 than the positions of the lateral pieces 36a and 36b (portions of the upper guide portions 36a, 39a, and 46a) are. This makes it possible to suppress transfer of stress applied to the rotating portion 23 from the bracket 92, to the front-side locking pieces 49. Therefore, it is possible to favorably keep a state in which the front-side locking pieces 49 are locked to the front side locking protrusions 41 and thus prevent the first divided part 20 and the second divided part 30 from being unintentionally released (separated).
Furthermore, with Embodiment 1, excellent space efficiency is achieved since the upper-side opening 22 of the insertion hole 19 is open in the upper surface of the wire guide device 10, the wires 110 are drawn upward, and the upper guide portions 36a, 39a, and 46a are provided on the upper walls 11 and 12 through which the wires 110 are drawn. In particular, an increase in size in the width direction in which the wire guide device 10 pivots can be suppressed, thus making it possible to improve the installability in vehicles and the like and to facilitate application to the layout. In addition, since the upper ends of the tubular portions 26 are located higher than the upper end of the vertical piece 39a, the size in the vertical direction of the entire wire guide device 10 is not increased.
Furthermore, the lower guide portions 36b, 39b, and 46b are also provided in addition to the upper guide portions 36a, 39a, and 46a, and therefore, the combining operations of the first divided part 20 and the second divided part 30 are more stably guided.
Moreover, since the first divided part 20 includes the coupling portions 31 to which the link part 121 located at an end portion of the cable guide 120 is to be pivotably coupled, the wire guide device 10 and the cable guide 120 can be attached to each other by coupling the link part 121 to the first divided part 20, and thus the burden of performing the attachment operation can be reduced.
The embodiments disclosed herein are exemplary in all respects, and should be construed as being not limitative.
Although the wire guide device is installed at an end portion on the sliding door side of the cable guide in Embodiment 1 above, the wire guide device may be installed at an end portion on the vehicle body side of the cable guide in other embodiments.
Although the wire guide device is provided in a wire harness for a sliding door in Embodiment 1 above, the wire guide device can be provided in various wire harnesses including a cable guide in other embodiments.
Although the vertical movement restriction portions are provided on the upper wall, the lower wall, and the end wall in Embodiment 1 above, it is sufficient that the vertical movement restriction portions are provided on any one or two of the upper wall, the lower wall, and the end wall in other embodiments.
Although the slide restriction portions are provided on the upper wall and the lower wall in Embodiment 1 above, the slide restriction portion may be provided on one of the upper wall and the lower wall in other embodiments.
Although the upper end of the tubular portion is located above the upper ends of the upper guide portions in Embodiment 1 above, the upper end of the tubular portion may be as high as the upper ends of the upper guide portions in other embodiments.
Although the restriction portion includes the vertical movement restriction portion and the slide restriction portion in Embodiment 1 above, it is sufficient that the restriction portion includes one of the vertical movement restriction portion and the slide restriction portion in other embodiments.
From the foregoing, it will be appreciated that various exemplary embodiments of the present disclosure have been described herein for purposes of illustration, and that various modifications may be made without departing from the scope and spirit of the present disclosure. Accordingly, the various exemplary embodiments disclosed herein are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
