Description

The present invention relates to a rotary connector device.

Conventionally, a rotary connector device for electrically connecting members that rotate relative to each other, such as a steering wheel of an automobile and a steering column, has been known. Patent Documents 1 to 4 disclose this type of rotary connector device, respectively.

The rotary connector device of Patent Documents 1 and 2 includes an outer case, an inner case, and a flat cable. The inner case is rotatable relative to the outer case. The flat cable is stored inside a cable storage portion (hereinafter, referred to as a cable storage space) formed by an inner case and an outer case.

In the cable accommodation space, the flat cable is wound in one direction and then in the opposite direction so that the winding direction is reversed. Then, the inner case can be rotated in one direction or the opposite direction by the amount corresponding to the length of the extra wound flat cable.

Here, the rotary connector device needs to be attached to a predetermined position of an automobile or the like in a state where the number of times the inner case can be rotated in one direction and the number of times it can be rotated in the opposite direction are equal. The position of the inner case at this time is called a neutral position, and the state at this time is called a neutral state.

In Patent Documents 1 and 2, a configuration in which a viewing window is formed in the inner case is adopted in consideration of the fact that the rotary connector device must be attached in a neutral state. When the inner case is in the neutral position, the position of the viewing window is set so that the inverted portion (U-shaped portion) of the flat cable can be visually recognized from the viewing window.

Further, in Patent Document 1, a predetermined mark is given to a portion corresponding to the inverted portion of the flat cable. In Patent Document 2, a marking is given to the inverted portion of the flat cable as in Patent Document 1, and a marking corresponding to the marking of the flat cable is given to the viewing window. According to Patent Documents 1 and 2, the neutral state can be easily confirmed by this.

Similar to Patent Documents 1 and 2, the rotary connector device of Patent Document 3 includes an outer case, an inner case, a flat cable, and a viewing window. A lens is provided in the viewing window. This lens can magnify and display the inverted part of the cable that can be seen from the viewing window. Patent Document 3 states that the neutral state can be easily confirmed by this.

Similar to Patent Documents 1 and 2, the rotary connector device of Patent Document 4 includes an outer case, an inner case, and a plurality of flat cables. This rotary connector device includes two viewing windows and an alignment mark. Multiple flat cables include colored cables that are colored differently than other flat cables. In the configuration of Patent Document 4, if the inverted portion of the flat cable that is not a colored cable can be visually recognized from each of the two viewing windows in a state where the alignment marks match, it is determined that the state is neutral. If it is not, it can be judged that the state is not neutral. Patent Document 4 states that the neutral state can be easily confirmed by this.

JP-A-2007-320450 Japanese Unexamined Patent Publication No. 2008-030713 Japanese Unexamined Patent Publication No. 2014-238970 Japanese Unexamined Patent Publication No. 2014-032762

In any of the configurations of Patent Documents 1 to 4, the cable accommodating space is covered by the outer case and the inner case forming the cable accommodating space. Then, daylighting to this cable accommodation space is performed through a relatively small viewing window. Therefore, the inside of the cable accommodation space was often darkened. Therefore, the visibility of the flat cable arranged in the cable accommodation space is poor, and it may be difficult to confirm the neutral state.

The present invention has been made in view of the above circumstances, and an object of the present invention is to improve the visibility of a flat cable from a viewing window and to provide a rotary connector device capable of easily confirming a neutral state.

That is, this rotary connector device includes a first member, a second member, and a strip-shaped cable. The second member is rotatably attached to the first member. The cable is arranged in an annular cable accommodating space formed between the first member and the second member, and is wound in one direction and the opposite direction. A viewing window is formed in the second member. The reversing portion can be visually recognized by this viewing window. The reversing portion is a portion where the rotation direction of the cable changes when the second member is in the neutral position. The first member is provided with an facing portion that can face the viewing window via the cable accommodating space. The facing portion reflects light incident on the cable accommodating space from the viewing window and has a light reflectance higher than the light reflectance of the second member, or the cable from the viewing window. It is a light emitting part that emits light by the light incident on the accommodation space.

As a result, the light incident on the cable accommodation space from the viewing window is effectively reflected by the reflecting portion, or the light emitting portion emits light by this light, and the cable is at least in the area of the cable accommodation space facing the viewing window.

(B) A cross-sectional view taken along the line AA of (a). Sectional drawing of the steering roll connector which concerns on 2nd Embodiment of this invention.

Next, embodiments of the invention will be described with reference to the drawings. FIG. 1 is an external perspective view showing the overall configuration of the steering roll connector 1 according to the first embodiment of the present invention. FIG. 2 is an exploded perspective view of the steering roll connector 1.

The steering roll connector (rotary connector device) 1 of the first embodiment shown in FIGS. 1 and 2 is used by being attached to a predetermined position in an automobile or the like. The steering roll connector 1 includes a stator (first member) 11 and a rotator (second member) 12.

As shown in FIG. 2, the stator 11 includes a fixed-side ring plate 21 and an outer tubular portion 31. The fixed side ring plate 21 is formed in a ring shape. The outer tubular portion 31 is formed in a cylindrical shape. The outer tubular portion 31 is fixed to the outer edge portion of the fixed side ring plate 21. The stator 11 is fixed to an appropriate member on the vehicle body side of the automobile, for example, a combination bracket switch (not shown) of a steering column. The stator 11 is attached so as to be rotatable relative to the steering shaft.

The rotator 12 includes a rotating side ring plate 22 and an inner cylinder portion 32. The rotating side ring plate 22 is formed in a ring shape. The inner tubular portion 32 is formed in a cylindrical shape. The inner cylinder portion 32 is integrally formed with the rotating side ring plate 22 so as to extend vertically from the inner edge of the rotating side ring plate 22. The steering shaft is inserted into the tubular hole of the inner tubular portion 32. The rotator 12 is provided so as to rotate integrally with the inserted steering shaft and to rotate relative to the stator 11.

The stator 11 and the rotator 12 are formed with recesses 11a and 12a for attaching the fixing pins 17, respectively. By attaching the fixing pins 17 to the recesses 11a and 12a of the stator 11 and the rotator 12, the rotator 12 can be locked so as not to rotate with respect to the stator 11.

The fixing pin 17 is temporarily attached so that the position of the rotator 12 does not deviate from the neutral position when the steering roll connector 1 is attached to the vehicle body. After the steering roll connector 1 is appropriately attached to the vehicle body, the rotator 12 can be rotated with respect to the stator 11 by breaking off the fixing pin 17 in the middle.

As shown in FIG. 1, the stator 11 and the rotator 12 are provided with triangular marks 18 and 19, respectively. When the positions of the marks 18 and 19 of the two polygons match, it means that the rotation phase of the rotator 12 is equal to the rotation phase of the above-mentioned neutral position. However, since the rotator 12 can rotate with respect to the stator 11 a plurality of times, the rotator 12 is not necessarily in the neutral position if the marks 18 and 19 match.

A first connector 41 is attached to the stator 11, and a second connector 42 is attached to the rotator 12. The second connector 42 rotates integrally with the rotation of the rotator 12. The first connector 41 and the second connector 42 are configured so that cables drawn from external electric circuits (for example, a horn switch, an airbag module, a power supply, an ECU, etc.) can be connected to each other.

A cable accommodating space 15, which is an annular space, is formed between the stator 11 and the rotator 12. Specifically, the cable accommodating space 15 includes a fixed side ring plate 21 and a rotating side ring plate 22 arranged so as to face each other, and an outer cylinder portion 31 and an inner cylinder portion 32 arranged so as to face each other. It is a space surrounded by.

A flexible flat cable (cable) 14 is accommodated in the cable accommodating space 15. In this embodiment, two flexible flat cables 14 are provided.

As shown in FIG. 3, the flexible flat cable 14 is housed in the cable storage space 15 in a state of being appropriately wound so as to overlap each other with the other flexible flat cables 14. The first end portion 14a of the flexible flat cable 14 is connected to the first connector 41. The second end 14b of the flexible flat cable 14 is connected to the second connector 42.

In the cable accommodating space 15, as shown in FIG. 3, the flexible flat cable 14 is accommodated so as to be wound in one of the circumferential directions of the cable accommodating space 15 (the circumferential direction of the outer tubular portion 31 and the inner tubular portion 32). Has been done. The flexible flat cable 14 is pulled out from the first connector 41 side to the cable accommodating space 15 in a state where the first end portion 14a is connected to the first connector 41. The flexible flat cable 14 is wound clockwise along the inner peripheral surface of the outer tubular portion 31.

One of the two flexible flat cables 14 is folded back in a U shape at the first reversing portion 61 to reverse the direction. The other flexible flat cable 14 is folded back in a U shape at the second reversing portion 62 to reverse the direction.

After reversing the orientation of each of the first reversing portion 61 and the second reversing portion 62, the flexible flat cable 14 is wound counterclockwise along the outer peripheral surface of the inner tubular portion 32. Then, the flexible flat cable 14 is finally pulled out from the cable accommodating space 15 side, and the second end portion 14b of the flexible flat cable 14 is connected to the second connector 42.

In this way, the flexible flat cable 14 is wound so as to have a slack of an appropriate length in the cable accommodating space 15, and the length of the slack changes as the rotator 12 rotates with respect to the stator 11. .. As a result, even when the rotator 12 rotates with respect to the stator 11, the electrical connection between the first connector 41 and the second connector 42 can be secured.

Next, with reference to FIGS. 4 and 5, a configuration for confirming that the steering roll connector 1 is in the neutral state will be described. FIG. 4 is a plan view of the steering roll connector 1. FIG. 5A is an enlarged view showing in detail how the flexible flat cable 14 and the facing portion 72 can be seen from the viewing window 70. FIG. 5B is a cross-sectional view taken along the line AA of FIG. 5A.

As described above, when manufacturing an automobile or the like, the steering shaft is adjusted in advance so as to be in a neutral state. The steering roll connector 1 is fixed in a neutral state by a fixing pin 17, and is attached to the above-mentioned predetermined position while maintaining the neutral state.

When removing the steering roll connector 1 for repair or the like, the steering shaft is adjusted in advance so as to be in the neutral state. Then, after removing the steering roll connector 1 and performing the work, the steering roll connector 1 is adjusted so as to be in a neutral state, and the steering roll connector 1 is reattached to a predetermined position. By matching the neutral state of the steering shaft with the neutral state of the steering roll connector 1 in this way, it is possible to prevent the flexible flat cable 14 from being damaged due to the rotation of the rotator 12 beyond the rotatable range.

The steering roll connector 1 of the present embodiment pays attention to the fact that the second reversing portion 62 of the flexible flat cable 14 moves according to the rotation of the rotator 12, and the operator utilizes the position of the second reversing portion 62. It is configured so that the neutral state can be confirmed. Specifically, a viewing window 70 is formed in the rotator 12 to make the flexible flat cable 14 arranged in the cable accommodating space 15 visible.

The viewing window 70 is provided on the rotating side ring plate 22 of the rotator 12. The viewing window 70 is made of a transparent plate-shaped member and is fixed to a through hole formed in the rotating side ring plate 22 of the rotator 12. The position of the viewing window 70, the length of the flexible flat cable 14, and the like are determined so that the second reversing portion 62 appears in the viewing window 70 when the steering roll connector 1 is in the neutral state. The position and size of the viewing window 70 can be arbitrarily set.

Here, since the cable accommodating space 15 is covered with the stator 11 and the rotator 12, which are opaque members, it is not possible to secure sufficient brightness only with the viewing window 70, and the inside tends to be dark. .. Therefore, the visibility of the flexible flat cable 14 is often poor. In this regard, in the present embodiment, the visibility of the flexible flat cable 14 is improved by the following configuration.

As shown in FIG. 5, the steering roll connector 1 includes a facing portion 72. As shown in FIG. 2, the facing portion 72 is provided in a region of the stator 11 that can face the viewing window 70 with the cable accommodating space 15 in between. In the present embodiment, the facing portion 72 is configured as a reflecting portion that reflects external light (visible light) incident on the cable accommodation space 15 from the viewing window 70. The opposing portion 72 as the reflecting portion has a light reflectance higher than the light reflectance of the rotator 12 (strictly speaking, the reflectance of the portion where the rotator 12 faces the cable accommodation space 15). ing.

In the present embodiment, the facing portion 72 is provided on the fixed side ring plate 21 of the stator 11. The facing portion 72 is arranged so as to face the viewing window 70 in the rotation axis direction of the rotator 12 in a state where the rotator 12 is rotated so that the positions of the marks 18 and 19 coincide with each other. The shape and size of the facing portion 72 are defined so that the facing portion 72 can face the entire opening of the viewing window 70 in a state where the marks 18 and 19 match. However, the facing portion 72 may be configured to face only a part of the viewing window 70.

The color of the facing portion 72 is a color that reflects a large amount of external light (hereinafter, may be simply referred to as light) incident on the cable accommodation space 15 from the viewing window 70. In the present embodiment, since the flexible flat cable 14 is white, a color different from the color of the flexible flat cable 14 is adopted as the color of the facing portion 72. For example, as the color of the facing portion 72, a yellowish color can be mentioned.

As a result, when the cable accommodating space 15 is viewed from the viewing window 70, the flexible flat cable 14 can be visually recognized on the front side, and the facing portion 72 can be seen on the back side of the flexible flat cable 14. At this time, sufficient brightness for visually recognizing the flexible flat cable 14 can be obtained by the light reflected by the facing portion 72 in at least the region of the cable accommodating space 15 facing the viewing window 70.

Therefore, it becomes easy to grasp the state of the flexible flat cable 14 at a position visible from the viewing window 70 in the cable accommodating space 15. Therefore, it is possible to easily confirm whether or not the second reversing portion 62 of the flexible flat cable 14 appears in the viewing window 70, that is, whether or not the rotator 12 is in the neutral position.

In the present embodiment, the facing portion 72 is integrally formed with the stator 11. Specifically, at least a part of the fixed side ring plate 21 is configured to have the above-mentioned color, and this portion constitutes the facing portion 72. This configuration can be realized, for example, by two-color molding.

As described above, in the present embodiment, the reflectance of the facing portion 72 is higher than the reflectance of the rotator 12. Furthermore, the reflectance of the facing portion 72 is higher than the reflectance of light in other portions of the stator 11 excluding the portion where the facing portion 72 is provided. For example, the facing portion 72 has a color that reflects a large amount of light (yellowish color, etc.), while the other portion of the fixed side ring plate 21 has a color different from the above (for example, black). There is.

Instead of making only a part of the color of the fixed side ring plate 21 different from the others, the entire fixed side ring plate 21 may be made different from the color of the outer cylinder portion 31. Alternatively, the entire stator 11 including the fixed side ring plate 21 and the outer cylinder portion 31 may be different from the color of the rotator 12.

As described above, the steering roll connector 1 of the present embodiment includes a stator 11, a rotator 12, and a strip-shaped flexible flat cable 14. The rotator 12 is attached so as to be rotatable relative to the stator 11. The flexible flat cable 14 is arranged in an annular cable accommodating space 15 formed between the stator 11 and the rotator 12, and is wound in one direction and the opposite direction. A viewing window 70 is formed on the rotator 12. The viewing window 70 makes the second reversing portion 62 visible. The second reversing portion 62 is a portion where the winding direction of the flexible flat cable 14 changes when the rotator 12 is in the neutral position. The stator 11 is provided with a facing portion 72 facing the viewing window 70 via the cable accommodating space 15. The facing portion 72 is configured as a reflecting portion that reflects light incident on the cable accommodating space 15 from the viewing window 70. The facing portion 72 has a light reflectance higher than the light reflectance of the rotator 12.

As a result, the light incident on the cable accommodating space 15 from the viewing window 70 is effectively reflected by the facing portion 72, and the flexible flat cable 14 is visually recognized at least in the area of the cable accommodating space 15 facing the viewing window 70. It is possible to secure sufficient brightness for the purpose. Therefore, the visibility of the flexible flat cable 14 via the viewing window 70 can be improved. Therefore, it can be easily confirmed that the rotator 12 is in the neutral position. That is, it can be easily confirmed that the steering roll connector 1 is in the neutral state.

In the present embodiment, the facing portion 72 is configured as a reflecting portion. It has a light reflectance higher than the light reflectance of the portion of the stator 11 excluding the portion where the facing portion 72 is provided (the portion other than the portion where the facing portion 72 is installed).

As a result, the brightness of the viewing window 70 can be ensured.

In the present embodiment, the color of the facing portion 72 is different from the color of the flexible flat cable 14. As described above, in the present embodiment, the color of the flexible flat cable 14 is white, and the color of the facing portion 72 is a yellowish color.

As a result, the flexible flat cable 14 can be visually emphasized in relation to the color of the facing portion 72. Therefore, the visibility of the flexible flat cable 14 can be further improved.

In the present embodiment, the facing portion 72 is integrally formed with the stator 11.

As a result, the number of parts can be reduced and the facing portion 72 can be easily configured.

Next, the second embodiment of the present invention will be described. FIG. 6 is a cross-sectional view of the steering roll connector 1x according to the second embodiment of the present invention. In the description of the present embodiment, the same reference numerals may be given to the same or similar members as those in the above-described embodiment, and the description may be omitted.

The steering roll connector 1x of the present embodiment is different from the first embodiment in that the facing portion 72x is composed of a member different from the stator 11.

As shown in FIG. 6, the facing portion 72x is composed of a sheet-like member or a film-like member. The facing portion 72x is fixed to the fixed side ring plate 21 by an appropriate method such as adhesion. It is preferable that the thickness of the sheet-shaped member or the film-shaped member is small enough not to hinder the movement of the first reversing portion 61 and the second reversing portion 62 of the flexible flat cable 14.

In the example of FIG. 6, a shallow recess is formed in the fixed side ring plate 21. The facing portion 72x is arranged inside the recess. As a result, it is possible to prevent the flexible flat cable 14 from being caught in the movement of the flexible flat cable 14 inside the cable accommodating space 15. However, this recess may be omitted.

In the present embodiment, the entire sheet-like member or film-like member constituting the facing portion 72x has a yellowish color. Instead, only the surface of the sheet-like member or the film-like member may be colored to have the color, for example, by applying a paint to the surface. With the above configuration, the same effect as that of the first embodiment can be obtained.

Further, the facing portion 72 may be composed of a sheet-like member or a film-like member having a property of reflecting a large amount of external light, and may be composed of, for example, a mirror. Alternatively, the facing portion 72 can be realized by the plating film.

As described above, in the present embodiment, the facing portion 72 is composed of a sheet-like member or a film-like member.

As a result, the facing portion 72 can be easily provided on the stator 11.

In the present embodiment, the facing portion 72 may be configured by applying a paint to the surface of the member.

In this case, a thin and compact facing portion 72 can be realized. Further, the facing portion 72 can be easily applied to the existing steering roll connector.

In the present embodiment, the facing portion 72 may also be composed of a plating film.

In this case, a thin and compact facing portion 72 can be realized.

In addition, in the above-mentioned first embodiment and the second embodiment, the facing portion 72 may be configured as a light emitting portion instead of being configured as a reflecting portion.

This light emitting unit emits light (visible light) incident on the cable accommodating space 15 from the viewing window 70. The light emitting unit can be, for example, a member having a fluorescent material (for example, a fluorescent seal or the like). Further, as the light emitting portion, a member coated with a luminous paint (phosphorescent paint) or the like can also be used.

In this configuration, it is possible to secure sufficient brightness for visually recognizing the flexible flat cable 14 by the light emitted from the light emitting unit itself.

As described above, in the steering roll connector 1 of the above-described embodiment, the facing portion 72 may be a light emitting portion. The light emitting unit emits light by the light incident on the cable accommodating space 15 from the viewing window 70.

As a result, the facing portion 72 (light emitting portion) emits light due to the light incident on the cable accommodation space 15 from the viewing window 70, which is suitable for visually confirming whether or not the flexible flat cable 14 appears in the viewing window 70. Sufficient brightness can be secured.

Although preferred embodiments and modifications of the present invention have been described above, the above configuration can be changed as follows, for example.

The color of the stator 11 can be changed as appropriate, including the color of the facing portion 72. The color of the rotator 12 and the color of the flexible flat cable 14 can also be changed as appropriate.

The facing portions 72 and 72x are arranged so as to have a phase corresponding to the phase of the viewing window 70 at the neutral position of the rotator 12. Therefore, by confirming whether or not the facing portions 72 and 72x can be seen from the viewing window 70, it is possible to replace the confirmation as to whether or not the two marks 18 and 19 match. From this, the marks 18 and 19 can be omitted.

The facing portions 72, 72x can also be formed in a ring shape along the circumferential direction of the cable accommodating space 15. In this case, the facing portions 72 and 72x face the viewing window 70 even if the rotator 12 is not in the neutral position. With this configuration, the brightness of the viewing window 70 can be further increased.

The number of flexible flat cables 14 accommodated in the cable accommodating space may be one or three or more.

The direction in which the flexible flat cable 14 is wound in the cable accommodating space may be opposite to that in the above embodiment.

The rotary connector device of the present invention is not limited to the portion related to the steering of an automobile, and can be widely used for the purpose of electrically connecting the rotating side and the fixed side.

In view of the above teachings, it is clear that the present invention can take many modified and modified forms. Therefore, it should be understood that the present invention may be practiced in a manner other than that described herein, within the scope of the appended claims.
