Description

  The present invention includes, for example, a rotation fixing device that fixes a relative rotation position between a stator and a rotator in a rotation connector device that electrically connects a steering wheel side and a vehicle body side of an automobile, and a rotation fixing device. The present invention relates to a rotating connector device.

  2. Description of the Related Art A rotary connector device mounted on a vehicle such as an automobile is mainly configured by assembling coaxially a stator that is fixed to a vehicle body side and a rotator that is assembled to a steering wheel side so as to be relatively rotatable. Furthermore, a flexible flat cable (hereinafter referred to as “FFC”) is accommodated in an accommodation space formed by the stator and the rotator so as to follow the rotation of the steering wheel so as to be wound and unwound.

  When such a rotary connector device is assembled to a vehicle body or a steering wheel, the rotator may rotate relative to the stator and the FFC winding state may be biased. For this reason, when the steering wheel is assembled with a deviation between the neutral position in the rotation direction of the steering wheel and the neutral position of the rotary connector device, the FFC may be broken when the steering wheel is steered.

  Therefore, for example, as shown in Patent Document 1, a temporary fixing pin is provided so as to be able to be inserted / removed in order to temporarily fix the stator and the rotator to the neutral position so that the neutral position can be maintained until it is assembled to the vehicle body or the steering wheel. It is said that the temporary fixing pin can be assembled to the neutral position of the steering wheel and the neutral position of the rotary connector device by removing the temporary fixing pin during assembly. Yes.

  Thus, the temporary fixing pin that temporarily fixes the neutral position of the rotary connector device until assembly must be removed in the state of assembly to the vehicle body, and must not be forgotten to be removed. Moreover, it needs to be easily removable from the viewpoint of workability. Therefore, the temporary fixing pin is configured to protrude greatly from the upper surface of the rotary connector device so that the temporary fixing pin can be clearly seen from the outside and can be easily removed.

  However, for example, during an assembly operation of the rotary connector device, if an unexpected external force is applied due to a temporary fixing pin that protrudes greatly from the upper surface of the rotary connector device coming into contact with something, the temporary fixing pin is inadvertently detached and becomes neutral. There was a risk that the position could not be maintained.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a rotary fixture and a rotary connector device that can prevent an unexpected external force from acting on an operation portion that protrudes outside the rotary connector device in the inserted state and thereby accidentally coming off. And

The present invention includes an annular stator, an annular rotator that rotates relative to the stator, and a belt-like cable that is wound and accommodated in an annular cable housing space formed between the stator and the rotator. A rotating fixture that contacts the stator and the rotator in the rotating connector device to fix a relative rotational position of the stator and the rotator, the insertion portion being inserted into the rotating connector device; protrudes from the rotary connector in, as well as constituted by an operation portion for insertion and removal operation, the operating unit, Bei example a thin portion the operation unit external force is applied to tilt with respect to the insertion portion, the operation The operation part main body having a part opened, and an open part in the operation part main body are connected to each other with higher deformability than the operation part main body. Constituted by a part, characterized in that a thin portion in the operation portion body.

  The present invention also provides an annular stator, an annular rotator that rotates relative to the stator, and a belt-shaped cable that is wound and accommodated in an annular cable housing space formed between the stator and the rotator. The rotary connector device is constituted by the rotary fixture described above.

Fixing the relative rotational position of the stator and the rotator by contacting the stator and the rotator described above is a concept including any fixed state, including temporary fixing for maintaining a neutral position before assembly. .
According to the present invention, it is possible to prevent the rotating fixture from being inadvertently detached due to an unexpected external force acting on the operation portion protruding to the outside of the rotary connector device in the inserted state.

  More details will be described below. In the insertion state in which the insertion portion is inserted into the rotary connector device, the operation portion for inserting / removing the rotary fixture protrudes to the outside of the rotary connector device, so it is apparent from the outside that the rotary fixture is inserted. It can be visually observed and is easy to remove.

  In this way, if an unexpected external force is applied to the operation unit protruding outside the rotary connector device, for example, by touching something during the assembly operation of the rotary connector device, the base of the operation unit, that is, the operation unit As a rotational force with the outer surface position portion of the rotary connector device as a fulcrum, a force in the detaching direction acts on the insertion portion, and the rotary fixture is released. On the other hand, since the operation portion to which the external force is applied is provided with a thin portion that tilts with respect to the insertion portion, the operation portion to which the external force is applied tilts in the direction in which the external force is applied. Therefore, it is possible to prevent a force in the separation direction from acting on the insertion portion as a rotational force with the outer surface position portion of the rotary connector device in the operation portion as described above as a fulcrum.

Even if a force is applied, it tilts in the direction in which the external force is applied. Therefore, a force in the detaching direction acts on the insertion portion as a rotational force with the outer surface position portion of the rotary connector device in the operation portion as described above as a fulcrum. Although it is possible to prevent inadvertent detachment, an operation part composed of only a thin part with a high inclination cannot be self-supporting, and it becomes difficult to perform a removal operation.

  Therefore, the present invention is a case where the rotational fixture in the inserted state can be clearly seen, the removal operation is easy, and furthermore, an unexpected external force is applied to the operation portion protruding to the outside of the rotary connector device. However, it is possible to prevent the rotating fixture from being inadvertently detached.

Further, according to the present invention, the rotation fixture can be easily detached from the rotation connector device.
More specifically, when the operation unit is configured only by an open ring-shaped operation unit body that is partially opened, when a force in the disengagement direction is applied for the disengagement operation of the rotary fixture with respect to the rotary connector device, The operating unit body is deformed, the force for the detachment operation is decentered and sufficient force cannot be applied in the insertion / removal direction, and an extra force is required for the detachment operation. growing. On the other hand, since the operation unit is configured by an open annular operation unit main body that is partially opened and a connection unit that connects the open part of the operation unit main body, deformation of the operation unit due to the detachment operation can be reduced. Can be easily separated.

  In addition, compared to the case where the operation unit is originally constituted by only the closed-ring operation unit main body, the operation unit main body that connects the open-ring operation unit main body partially opened and the open part of the operation unit main body. Since the operation part is composed of a connection part with higher deformability, the tiltability of the operation part with the thin part provided in the operation part body (ease of tilting of the operation part against unexpected external force) is improved. When an unexpected external force acts on the operation unit, it can be reliably tilted.

As an aspect of this invention, the operation portion connected along a virtual plane in which the insertion portion is constituted by a perpendicular direction and the insertion direction orthogonal to the direction crossing the insertion direction to be inserted into the interior of the rotary connector device The thin portion may have a predetermined thickness in the cross direction, and the thin portion may be formed by the concave portion in the cross direction, and the thin connection portion may be formed in the cross direction.

  According to the present invention, an operation unit having a desired strength required for the detachment operation can be configured, and the operation unit can be reliably tilted in the crossing direction against an unexpected external force. Moreover, a connection part with a higher deformability can be easily comprised with respect to the operation part main body in the crossing direction by comprising a connection part by the thin connection part thin in the said crossing direction.

Moreover, as an aspect of this invention, the said thin connection part and the said thin part can be arrange | positioned at the one side of the said cross direction in thickness.
According to the present invention, it is possible to configure a rotating fixture with high tiltability. Temporarily, when the thin-walled portion is arranged on one side in the thickness and the thin-walled connecting portion is arranged on the other side in the thickness, when the operation unit body tilts with the thin-walled portion serving as a fulcrum, the position further shifted from the fulcrum by the thickness in the tilting direction Although the load against the tilting of the operation unit body is increased by the thin-walled connecting portion and the tiltability is lowered, the thin-walled portion becomes the center of tilting in the tilting direction by arranging the thin-walled portion and the thin-walled connecting portion on one side of the thickness. Since the distance between the portion and the thin connecting portion can be made closer, the tiltability of the operation portion can be improved.

Further, as an aspect of the present invention, in the inserted state, a protruding support portion that contacts the outer surface of the rotary connector device in the insertion direction and protrudes and supports both sides in the intersecting direction can be provided.
According to the present invention, it is possible to reliably prevent the force in the separation direction from acting on the insertion portion by tilting the operation portion with the thin portion serving as a fulcrum.

  More specifically, even if an unexpected external force is applied to the operation portion protruding to the outside of the rotary connector device, the protruding support portion comes into contact with the outer surface of the rotary connector device so that the protruding support portion It is possible to prevent an external force from acting on the inner insertion portion. Therefore, an unexpected external force acts only on the operation part, and the thin part can be reliably tilted with the fulcrum as a fulcrum, so that the rotating fixture can be further reliably prevented from being accidentally detached.

In an embodiment of the present invention, in the inserted state, the projecting support portion is disposed inside the stator and the side walls consist of an annular bottom plate body, a cylindrical side wall member along the outer edge of the bottom plate member It can abut against both of the substantially disk-shaped rotators.
According to the present invention, since the projecting support portion comes into contact with both the stator and the rotator, it can be tilted more reliably.

  Further, as an aspect of the present invention, the insertion portion is provided with a locking portion that locks in a disengagement direction with respect to the locked portion inside the rotary connector device, and the locking portion is elastic to the locking portion. A deformable slit can be provided.

  According to the present invention, since the locking portion that is locked in the disengagement direction with respect to the locked portion inside the rotary connector device can be elastically deformed in the inserted state, plasticity is obtained when the locked portion is engaged / disengaged by the insertion / removal operation Even if insertion / removal is repeated without deformation, the locking portion can be reliably locked with respect to the locked portion, and a rotating fixture that can be inserted / removed multiple times can be configured.

  According to the present invention, it is possible to provide a rotary fixing device and a rotary connector device that can prevent an unexpected external force from acting on an operation portion that protrudes to the outside of the rotary connector device in an inserted state, and thereby accidentally coming off.

The main body base portion 11a and the arc portion 11b are connected to each other on the back side Xb by the thin portion 13 that is thinned in the thickness direction X by 12.
Further, the main body base portion 11a below the thin-walled portion 13 has a substantially triangular shape when viewed from the front, and functions as a gripping portion 14 that is gripped by an operator and inserted when the neutral fixing pin 1 is inserted. Yes.

  The thin connecting portion 40 is configured such that the operation portion main body 11 and the thickness direction rear Xb are flush with each other, and the thickness in the thickness direction X is thinner than the height in the height direction Z. Therefore, the thin portion 13 and the thin connecting portion 40 are disposed in the thickness direction rear Xb in the operation portion 10.

  The projecting support portion 20 includes a rear-side projecting support portion 21 extending from the rear surface of the operation portion 10 in the thickness direction rear Xb between the lower end of the main body base portion 11a of the operation portion main body 11 and the upper end of the insertion portion 30 described later. There is a front-side protruding support portion 22 that extends in the thickness direction front Xa from the front of the operation portion 10.

A portion 22d is provided. The lower end of the fitting convex portion 22d is formed at a height corresponding to the lower end surface 21b of the rear side protruding support portion 21 and the lower end surface 22e on the rear side of the front side protruding support portion 22 in the height direction Z. Yes.
Further, the front-side protruding support part 22 is formed with a length about twice as long in the thickness direction X as compared with the back-side protruding support part 21.

  The insertion portion 30 extending downward in the height direction Z from the projecting support portion 20 is a portion that is inserted and fixed in an SRC 100 described later, and is a straight bar shape having a concave cross section with the thickness direction front Xa opened. Yes, a tapered portion 31 in the width direction Y for facilitating insertion into the SRC 100 is formed at the lower end.

Furthermore, a locking portion 32 that protrudes forward in the thickness direction Xa and is linearly formed in the width direction Y is provided below the surface of the insertion portion 30 in the thickness direction front Xa.
In addition, a slit 33 in the height direction Z that divides the locking portion 32 is formed in the central portion of the locking portion 32 in the width direction Y.

  The SRC 100 for inserting and fixing the neutral fixing pin 1 including the elements (10, 20, 30) in this way is fixed to the combination switch side (lower side) and the steering wheel side (upper side). Rotator 130 that is positioned on the side of the stator 110 and is rotatable relative to the stator 110, and an FFC (not shown) that is wound around an annular storage space S formed inside the stator 110 and the rotator 130. In addition, it is formed in a cylindrical shape having a through hole H that penetrates a steering shaft (not shown) at the center in plan view.

  The FFC (not shown) is configured by arranging a plurality of flat conductors arranged in a row in the width direction W at a predetermined interval, and arranging the plurality of flat conductors in parallel, and covering them with insulating coatings from both sides in the front and back directions.

  The stator 110 is fixed to a combination switch (not shown) attached to the steering column, is formed in a substantially annular shape having a circular hole in the center, and forms a ring-shaped stator body 111 constituting the bottom surface of the SRC 100, and an axial direction. And a sub-stator 120 that constitutes the cylindrical outer peripheral surface of the SRC 100 is assembled.

  The stator body 111 includes a stator-side connector portion 112 that protrudes downward on the outer peripheral side of the position where the sub-stator 120 is fixed, and includes a predetermined height along the outer edge of the stator body 111 including the stator-side connector portion 112. And a plurality of engagement frame bodies 114 that are engaged with and fixed to the sub-stator 120 at a predetermined interval so as to protrude upward from the side periphery 113.

  The stator side connector portion 112 is connected to an outer peripheral end portion of the FFC wound in the accommodation space S, and is formed to be connectable to an external connector on the combination switch side.

The sub-stator 120 includes a cylindrical side wall body 121 and a cover portion 122 that covers the upper portion of the stator-side connector portion 112 described above.
On the outer peripheral surface of the side wall main body 121, an outer peripheral abutting portion 123 that abuts on the upper surface of the side peripheral portion 113 of the stator main body 111 is provided at a position corresponding to between the engaging frame bodies 114, and the engaging frame body is provided. An engagement claw 124 that engages with the engagement frame 114 is provided at a location corresponding to 114.

  Further, the cover portion 122 is provided with an insertion opening 125 into which the insertion portion 30 of the neutral fixing pin 1 is inserted in a rectangular shape in a plan view in a tangential direction with respect to the center of the side wall body 121, and below the insertion opening 125. Inside the cover part 122, a locked protrusion 126 that is locked by the locking part 32 of the insertion part 30 is provided at a position corresponding to the locking part 32 in the inserted state (see FIG. 8).

  The rotator 130 has a ring-shaped top plate 131 in plan view that covers the upper end of the sub-stator 120 of the stator 110 so that an annular housing space S for housing an FFC (not shown) can be formed between the rotator 130 and the stator 110. The top plate 131 is integrally configured so as to be L-shaped in a single cross section with an inner peripheral portion 132 projecting downward in the axial direction from the inner peripheral edge.

  Further, a rotator side connector 133 protrudes upward in the height direction Z on the top surface of the top plate portion 131 of the rotator 130, and the rotator side connector 133 is an end portion on the inner peripheral side of the FFC in the accommodation space S. And an external connector connected to a horn on the steering wheel side, an air bag system, or the like.

Further, a fitting recess 134 into which the fitting projection 22d of the protruding support portion 20 of the neutral fixing pin 1 in the inserted state is fitted is provided at a position facing the rotator side connector 133 on the top surface of the top plate portion 131. Yes.
The rotator 130 is fixed in a relatively rotatable manner by sandwiching the stator 110 from above and below through a through hole H of the stator body 111 by a cylindrical fixing ring 140 disposed below the stator body 111. Has been.

  The SRC 100 configured by assembling the stator 110 and the rotator 130, each of which is configured as described above, so as to be relatively rotatable, winds the FFC connected to the stator-side connector portion 112 and the rotator-side connector 133 in the accommodating space S. Since it is housed, the rotator-side connector 133 can rotate relative to the stator-side connector portion 112 while being electrically connected.

  However, when the SRC 100 is assembled to the vehicle body or the steering wheel, when the rotator 130 rotates relative to the stator 110, the winding state of the FFC is biased. If it is assembled with a deviation from the neutral position of the rotary connector device, the FFC may break when the steering wheel is steered.

  Therefore, in the SRC 100, the grip portion 14 is gripped in a state where the rotator 130 is disposed at the neutral position with respect to the stator 110, and the insertion portion 30 of the neutral fixing pin 1 is inserted from the insertion opening 125. The SRC 100 can be fixed in the neutral position by fitting the fitting convex portion 22d of the front side protruding support portion 22 into the fitting concave portion 134 provided on the upper surface of the rotator 130.

  At this time, in the inside of the cover portion 122 in the sub-stator 120, the locking portion 32 of the insertion portion 30 is locked with the locked protrusion 126 formed inside the cover portion 122.

  More specifically, the locking portion 32 of the insertion portion 30 inserted into the cover portion 122 from the upper side to the lower side in the Z direction through the insertion opening 125 is locked while pressing the locked protrusion 126. It moves over the protrusion 126 and moves downward, and is locked in the height direction Z with respect to the locked protrusion 126. At this time, since the slit 33 is provided in the middle of the locking portion 32 formed in the insertion portion 30, the locking portion 32 is elastically deformed toward the slit 33. The locking portion 32 to be stopped can return to its original shape and be securely locked.

  As described above, the insertion portion 30 is fixed in the height direction Z with respect to the sub-stator 120 while the engagement portion 32 is vertically engaged with the engagement protrusion 126 inside the cover portion 122. In the attached state, the protruding support portion 20 is disposed along the normal direction passing through the center of the sub-stator 120, and the rear-side protruding support portion 21 is in contact with the upper surface 122 a of the cover portion 122 outside the insertion opening 125.

  Furthermore, the front-side protruding support portion 22 is in contact with the upper surface of the outer edge of the side wall body 121 on the inner side of the insertion opening 125, and the fitting convex portion 22d is fitted into the fitting concave portion 134 of the rotator 130 (see FIG. 5). As a result, the rotator 130 is rotationally fixed with respect to the sub-stator 120 and is rotationally fixed with respect to the stator 110 via the sub-stator 120, so that the neutral position of the SRC 100 can be fixed.

  The operation portion 10 of the neutral fixing pin 1 inserted and attached to the SRC 100 in this way is oriented along a tangential direction with respect to the center of the SRC 100, and is greatly increased from the upper surface of the SRC 100, that is, the upper surfaces of the rotator 130 and the sub-stator 120. Protruding.

  Therefore, in the insertion state in which the insertion portion 30 is inserted into the SRC 100, it is possible to clearly see from the outside that the neutral fixing pin 1 is inserted by the operation portion 10 protruding outside the SRC 100, and the removal operation. Easy to do.

  However, if an unexpected external force F in the thickness direction X is applied to the operation unit 10 that protrudes outside the SRC 100 in this way, for example, by contact with something during the assembly operation of the SRC 100, the root of the operation unit 10 As a rotational force with the upper portion of the SRC 100 in the operation portion 10 as a fulcrum, a force in the separation direction (upward in the height direction Z) acts on the insertion portion 30 to release the neutral fixing pin. Even if an unexpected external force F in the thickness direction X acts on the operation portion 10 of the neutral fixing pin 1, the thin portion 13 causes the operation portion 10 to tilt in the thickness direction X (see FIG. 5). A force in the detachment direction acts on the insertion portion 30 as a rotational force with the upper surface position of the thin portion 130 of the SRC 100 in the operation portion 10 as described above as a fulcrum, and the neutral fixing pin 1 is carelessly detached. It can be prevented.

  If the operation unit main body 11 is configured with the same thickness as the thin-walled portion 13 with high tiltability, even if an unexpected external force F is applied, the operation portion is tilted in the direction in which the external force F is applied. The force in the separation direction acts on the thin portion 13 as a rotational force with the outer surface position portion of the SRC 100 in the portion 10 as a fulcrum, so that it can be prevented from being inadvertently detached, but the same thickness as the thin portion 13 with high inclination The operation part main body 11 cannot stand by itself, and it becomes difficult to perform the removal operation.

  Therefore, the present invention is a case where the neutral fixing pin 1 in the inserted state can be clearly seen, the removal operation is easy, and furthermore, an unexpected external force is applied to the operation portion protruding to the outside of the SRC 100. However, it is possible to prevent the rotating fixture from being inadvertently detached.

  Conversely, even when an external force in the direction opposite to the external force F in the thickness direction X shown in FIG. 5 is applied, the space of the concave portion 12 constituting the thin portion 13 can be tilted as a deformation space.

  In addition, the operation unit 10 includes an open annular operation unit main body 11 that is partially opened, and a thin-walled connection unit 40 that connects the open part of the operation unit main body 11 and is more deformable than the operation unit main body 11. Since the thin portion 13 is disposed in the operation portion main body 11, the neutral fixing pin 1 can be easily detached from the SRC 100.

  More specifically, when the operation unit 10 is constituted only by an open ring-shaped operation unit body that is partially opened, if a force in the disengagement direction is applied for the disengagement operation of the neutral fixing pin with respect to the SRC 100, the open ring operation is performed. The main body is deformed, the force for the detachment operation is decentered and sufficient force cannot be applied in the insertion / removal direction, and an extra force is required for the detachment operation. Become. On the other hand, the operation unit 10 constituted by an open annular operation unit main body 11 partially opened and a thin connecting unit 40 that connects the open part of the operation unit main body 11 can reduce deformation caused by the detachment operation, and can be easily performed. You can leave.

  In addition, although the thin portion 13 is provided in the operation portion main body 11, compared to the case where the operation portion is originally constituted only by the closed annular operation portion main body, an open annular operation portion main body 11 partially opened, The operation unit 10 constituted by the thin connection part 40 that is connected to the opening part of the operation part main body 11 and is more deformable than the operation part main body 11 has improved tiltability, and an unexpected external force in the thickness direction X is applied to the operation part 10. Even if F acts, it can be reliably tilted.

  In addition, a thin portion 13 is provided in the operation portion main body 11 having a predetermined thickness along the imaginary plane constituted by the width direction Y and the height direction Z by a concave portion 12 recessed in the thickness direction X, and is thin in the thickness direction X. By providing the thin connection portion 40, the operation portion 10 having a desired strength required for the detachment operation is configured, and the operation portion 10 is reliably tilted in the thickness direction X with respect to the external force F in the unexpected thickness direction X. be able to. Further, since the thin connecting portion 40 is thin in the thickness direction X, the deformability is further improved in the thickness direction X compared to the operation portion main body 11.

  Moreover, since the thin connection part 40 and the thin part 13 are arrange | positioned in the thickness direction back Xb in the operation part 10, the neutral fixing pin 1 with high inclination can be comprised. Temporarily, when the thin portion 13 is disposed in the thickness direction rear Xb and the thin connection portion 40 is disposed in the thickness direction front Xa, when the operation portion main body 11 is tilted with the thin portion 13 as a fulcrum, the thickness is reduced from the fulcrum in the tilt direction. Further, the load that resists the tilting of the operation unit main body 11 is increased by the thin-walled connecting portion 40 at the shifted position and the tiltability is lowered. However, by arranging the thin-walled portion 13 and the thin-walled connecting portion 40 both in the thickness direction rear Xb. Since the distance between the thin portion 13 and the thin connecting portion 40 that are the tilt center in the tilt direction can be made closer, the tiltability of the operation portion 10 can be improved.

  Further, in the inserted state, the thin-walled portion 13 is provided as a fulcrum by providing projecting support portions 20 (21, 22) that abut against the outer surface of the SRC 100 in the height direction Z and project and support both sides in the thickness direction X. As a result, it is possible to reliably prevent the force in the detaching direction from acting on the insertion portion 30 by tilting the operation portion 10.

  More specifically, even if an unexpected external force F in the thickness direction X acts on the operation portion 10 that protrudes to the outside of the SRC 100, the protruding support portion 20 contacts the upper surface of the SRC 100 so as to be stretched. Therefore, it is possible to prevent the external force F from acting on the insertion portion 30 on the inner side than the 20. Therefore, the unexpected external force F in the thickness direction X acts only on the operating portion 10 and reliably tilts the operating portion 10 with the thin portion 13 as a fulcrum, thereby further preventing the neutral fixing pin 1 from being inadvertently removed. can do.

  Further, in the inserted state, the protruding support portion 20 can be tilted more reliably by coming into contact with both the substantially disk-like rotator 130 disposed inside the sub-stator 120 and the stator 110.

  In addition, the insertion portion 30 includes a locking portion 32 that locks the locking projection 126 inside the SRC 100 in the disengagement direction, and the locking portion 32 has a slit in which the locking portion 32 can be elastically deformed. By providing 33, the locking part 32 that locks in the disengagement direction with respect to the locked protrusion 126 inside the SRC 100 can be elastically deformed in the inserted state. Even if the insertion / removal is repeated without being plastically deformed at the time of engagement / disengagement, the engagement portion 32 can be reliably engaged with the engaged protrusion 126, and the neutral fixing pin 1 is inserted / removed a plurality of times. can do.
