Description

  The present invention relates to a steering roll connector that ensures electrical conduction between an electrical component of a steering wheel and a vehicle body by rotating a rotator with respect to a stator.

  As is conventionally known, the steering roll connector includes a fixed-side stator and a rotating-side rotator (see Patent Document 1). The storage space inside the stator and the rotator stores a spiral cable that can be tightened and loosened when the rotator is rotated. The steering roll connector is connected and fixed to the rotator so that the steering wheel can rotate integrally when the vehicle body is assembled. Electrical components (for example, an air bag device and switches) provided on the steering wheel are connected to the connector of the rotator, and are energized to the vehicle body side from the spiral cable in the steering roll connector through the connector of the stator.

  By the way, if the steering roll connector is assembled to the vehicle body in a state where the rotator is in a rotational position other than the neutral position, the number of rotations on one side of the steering roll connector is insufficient, so that the spiral cable in the steering roll connector is disconnected. May lead to If the spiral cable is disconnected, the air bag device and the horn do not function, and the switches around the steering wheel do not operate.

  Therefore, Patent Document 1 discloses a steering roll connector including an interlock mechanism that holds a neutral position so as not to rotate the rotator when the steering wheel is not assembled. In this interlock mechanism, when the steering wheel is not assembled, the interlock plate pushed up by the spring is fixed to the groove of the stator, and the rotator does not rotate. On the other hand, when assembled to the steering roll connector, the steering wheel pushes down the interlock plate, the interlock plate is detached from the groove of the stator, and the rotation of the rotator is permitted.

However, even if the interlock mechanism is provided in the steering roll connector, there is still a problem that the rotator is assembled to the vehicle body in a state where it is not in the neutral position.
An object of the present invention is to provide a steering roll connector that can further prevent the steering wheel from being assembled to the vehicle body when the rotator is not in the neutral position.

  The steering roll connector that solves the above-mentioned problem is restricted in rotation of the rotator by an interlock mechanism that is provided so as to rotate integrally with the rotator when the steering wheel is not attached. When the steering wheel is mounted, the rotator is positioned at the neutral position of rotation in the configuration in which the interlock mechanism is unlocked from the stator, thereby allowing the rotation of the rotator. Only when this is done, an assembly restricting mechanism for switching whether or not the steering wheel can be assembled is provided by allowing the interlock mechanism to be unlocked.

  According to this configuration, if the rotator is in the neutral position of rotation, the assembly restriction mechanism allows the interlock mechanism to be unlocked, so that the steering wheel can be assembled to the vehicle body as usual. Is possible. On the other hand, if the rotator is not in the neutral position of rotation, the interlock mechanism is not allowed to operate to unlock the interlock mechanism, so the interlock mechanism is released even if the steering wheel is assembled to the vehicle body. The steering wheel cannot be assembled to the car body. Therefore, it is possible to further prevent the steering wheel from being assembled to the vehicle body when the rotator is not in the neutral position.

  In the steering roll connector, the interlock mechanism includes an interlock plate that can reciprocate in the assembly direction of the steering wheel and can be locked to the stator, and a plate urging portion that pushes the interlock plate toward the stator. And a sleeve that supports the plate urging portion, and the assembly restriction mechanism switches whether the steering wheel can be assembled depending on whether the interlock plate can be operated to the unlock side. Is preferred. According to this configuration, when the rotator is not in the neutral position, the interlock mechanism is not operated by restricting the operation of the interlock plate, so that the interlock mechanism can be kept firmly locked. Is possible.

  In the steering roll connector, the assembly restricting mechanism is provided on the rotator and capable of switching the operating position of the restricting portion provided on the rotator, and a restricting portion on which a locking piece that is a lock portion of the interlock plate can be brought into contact. The assembly restricting mechanism is capable of moving the interlock plate to the unlocking side when the operating position in which the through groove of the restricting portion is located on the movement path of the locking piece is provided. And when the projecting piece of the restricting portion is located on the movement path of the locking piece by the switching projection with the rotation from the neutral position of the rotator, the unlocking side of the interlock plate It is preferable to disable the operation. According to this configuration, the operation of the interlock plate toward the unlock side can be disabled by a simple configuration in which the movement of the locking piece that is the lock portion of the interlock plate is restricted by the restriction portion. .

  In the steering roll connector, the restricting portion is a gear portion that rotates about an axis, and the assembly restricting mechanism is configured such that the switching protrusion rotates the gear portion in a process in which the rotator makes one round from a neutral position. Thus, it is preferable to switch the operating position of the gear portion. According to this configuration, since the restricting portion is the gear portion that rotates at its own position, when the operation of the assembly restricting mechanism is switched, the gear portion simply needs to move in its own position. Therefore, it is not necessary to increase the arrangement space of the parts required for the restricting portion, and there is no fear that the apparatus size will be increased.

  In the steering roll connector, the rotator is capable of rotating a plurality of turns in both directions with respect to the neutral position, and the gear portion is a plurality of pushed-in pushes that can selectively contact the switching protrusion when the rotator is rotated. And the assembly restricting mechanism is configured such that the switching protrusion selectively pushes the pushed portion of the gear portion every time the rotator makes one turn, thereby rotating the gear portion from the neutral gear position. It is preferable that the operation position of the gear portion is sequentially switched by moving one notch at a time. According to this configuration, even if the rotator has a structure in which the rotator rotates around in both directions from the neutral position, it is possible to prevent the interlock mechanism from being operated at each operating position.

  According to the present invention, it is possible to further prevent the steering wheel from being assembled to the vehicle body when the rotator is not in the neutral position.

Hereinafter, an embodiment of a steering roll connector will be described with reference to FIGS.
As shown in FIGS. 1 and 2, the steering roll connector 1 includes a stator 2 that is a fixed side in the steering roll connector 1, and a rotating rotator 3 that is assembled to the stator 2. The steering roll connector 1 includes a spiral cable (not shown) that electrically connects an air bag device and switches provided on a steering wheel 4 (FIG. 1 is partially shown) to the vehicle body side, and the interior of the stator 2 and the rotator 3. Store in. The side wall of the stator 2 is provided with a connector portion 5 to which wiring drawn from the vehicle body side is connected. On the upper wall of the rotator 3, a connector portion 6 to which wiring extending from switches provided on the steering wheel 4 is connected is provided.

  On the inner peripheral wall of the rotator 3, a plurality of connection protrusions 8a for connecting and fixing the steering wheel 4 are provided (only one is shown in FIG. 1). When the steering wheel 4 is rotated, the operating force is transmitted to the rotator 3 through the connecting projection 8a, and the rotator 3 and the steering wheel 4 are rotated synchronously. A confirmation window 7 is provided on the upper surface of the rotator 3 so that an internal cable can be visually recognized. The state of the spiral cable when the rotator 3 is rotated can be confirmed through the confirmation window 7.

  A steering shaft 8 serving as a rotation shaft of the steering wheel 4 is passed through a shaft insertion hole 9 provided in the center of the rotator 3 and a shaft insertion hole 10 provided in the center of the stator 2. The rotator 3 is fixed to the steering shaft 8 and rotates synchronously with the steering shaft 8. That is, when the steering wheel 4 and the steering shaft 8 rotate, the stator 2 does not rotate at the fixed position, and only the rotator 3 rotates relative to the stator 2 in synchronization with the steering shaft 8. Thereby, the electrical connection between the steering wheel 4 side and the vehicle body side when the steering wheel 4 is rotated is maintained.

  As shown in FIGS. 2 and 3, the steering roll connector 1 includes an interlock mechanism 11 that functions to secure a neutral position of the rotator when assembled to the vehicle body. This is because, for example, when the steering roll connector 1 is assembled to the vehicle body in a state where the rotator 3 is deviated from the neutral position (for example, a state where the rotator 3 is rotated once or twice from the neutral position to the right or left), This is because there is a possibility that when the steering wheel 4 is rotated in that direction, the cable in the steering roll connector 1 may be disconnected.

  As shown in FIG. 3, the interlock mechanism 11 includes an interlock plate 12 that can reciprocate in the assembly direction of the steering wheel 4 (the direction of arrow R in FIG. 3) and can be locked to the stator 2. A plate urging portion 13 that pushes the interlock plate 12 toward the stator 2 and a sleeve 14 that supports the plate urging portion 13 are provided. The interlock plate 12 is formed in a substantially ring shape, and the steering shaft 8 is inserted into the central shaft insertion hole 15. A shaft insertion hole 16 through which the steering shaft 8 is inserted is provided in the center of the sleeve 14. The shaft insertion holes 9, 10, 15, 16 are formed so that the hole centers are arranged on the same axis.

  A plurality (for example, four) of locking portions 17 that can be locked to the sleeve 14 are erected on the radial end edge of the sleeve 14. These locking portions 17 are arranged at equal intervals in the circumferential direction and have, for example, a snap fit shape. The interlock mechanism 11 is assembled to the rotator 3 by engaging the engaging portion 17 with the engaging protrusion 18 of the rotator 3 with the plate urging portion 13 interposed between the rotator 3 and the sleeve 14. Yes. As a result, the interlock mechanism 11 can rotate integrally with the rotator 3.

The plate urging portion 13 is interposed between the interlock plate 12 and the sleeve 14. The plate urging portion 13 of this example uses a coil spring.
The interlock plate 12 is provided with a locking piece 21 that can fix the rotator 3 to the stator 2 so as not to rotate. A plurality (two in this example) of the locking pieces 21 are provided on the edge of the interlock plate 12 and are arranged so as to be opposed to each other. The plurality of locking pieces 21 are formed so as to protrude outward in the radial direction. The locking piece 21 is fitted in a guide groove 22 provided inside the sleeve 14. A plurality of guide grooves 22 are provided for each locking piece 21 (two in this example), and guides the movement when the interlock plate 12 slides in the movable direction (the direction of arrow R in FIG. 3).

  As shown in FIG. 4, the stator 2 is formed with a locking groove 23 in which the locking piece 21 can be locked. A plurality (two in this example) of the locking grooves 23 are formed according to the number of the locking pieces 21 (however, only one is shown in FIG. 4). The locking groove 23 is formed at the periphery of the shaft insertion hole 10 of the stator 2 and is formed with a width W2 that is slightly larger than the width W1 of the locking piece 21.

  As shown in FIG. 5A, for example, when the steering wheel 4 is assembled to the steering column 24, the metal core 25 of the steering wheel 4 pushes the interlock plate 12 into the plate urging portion 13 against the urging force. As a result, the locking piece 21 of the interlock plate 12 is detached from the locking groove 23 of the stator 2. As a result, the interlock mechanism 11 is disabled (unlocked), and the rotator 3 can be rotated with respect to the stator 2.

  As shown in FIG. 5B, when the steering wheel 4 is removed from the steering column 24, the pushing by the metal core 25 is released, and the interlock plate 12 is lifted by the urging force of the plate urging portion 13, and the interlock The locking piece 21 of the plate 12 is locked in the locking groove 23 of the stator 2. As a result, the interlock mechanism 11 is enabled (locked state), and the rotator 3 cannot rotate with respect to the stator 2.

  As shown in FIGS. 3 and 4, the steering roll connector 1 includes an assembly restriction mechanism 28 that permits assembly of the steering wheel 4 to the vehicle body only when the rotator 3 is in the neutral position. The assembly restriction mechanism 28 of this example is one functional part of the interlock mechanism 11. The assembly restricting mechanism 28 allows the interlock mechanism 11 to operate when the rotational position of the rotator 3 is in the neutral position, thereby allowing the steering wheel 4 to be assembled, and the rotational position of the rotator 3 is not in the neutral position. In some cases, even if the interlock mechanism 11 can be unlocked (the interlock plate 12 can be lowered), by disabling the operation of the interlock mechanism 11, the steering wheel No assembly of 4 is permitted.

  As shown in FIGS. 6 and 7, the assembly restricting mechanism 28 includes a restricting portion 29 that can come into contact with the locking piece 21 of the interlock plate 12 and the operation of the restricting portion 29 according to the rotational position of the rotator 3. And a switching protrusion (switching gear) 30 for switching positions. The restricting portion 29 in this example is a gear portion 29a that can rotate around an axis. On the back surface of the restricting portion 29, a rotating shaft 31 is projected, and the rotating shaft 31 is pivotally supported in a shaft hole 32a of a wall portion (upper wall portion) 32 of the stator 2. The restricting portion 29 includes a pair of projecting pieces 33 and 34 that can be positioned on the movement path of the locking piece 21, and a through groove 35 that is a groove between the projecting pieces 33 and 34. On the upper surface of the restricting portion 29, a plurality of pressed protrusions 36 (three in this example) projectingly come into contact with the restricting portion 29. The restricting portion 29 is housed in a housing portion 37 that is recessed in a step shape on the wall portion 32 of the stator 2.

  The switching protrusion 30 protrudes from the inner surface of the rotator 3 and has, for example, a protrusion shape. The switching protrusion 30 selectively pushes one of the three pushed portions 36a to 36c for each circumference when the rotator 3 is rotated. For example, when the rotator 3 rotates from the neutral position in one direction (the direction of the arrow R1 in FIG. 6), the switching protrusion 30 abuts on the first pushed-in portion 36a during the first round, and the second round. At that time, the switching protrusion 30 abuts against the second pushed-in part 36b, thereby turning the restricting part 29 one notch in the same direction. On the other hand, when the rotator 3 rotates in the other direction (arrow R2 direction in FIG. 6) from the neutral position, the switching protrusion 30 abuts on the first pushed portion 36a during the first round, and the second round. At that time, the switching protrusion 30 abuts against the third pressed portion 36c, thereby turning the main gear one notch in the same direction.

Next, the operation of the steering roll connector 1 will be described with reference to FIGS.
As shown in FIG. 8, when the rotator 3 takes a neutral position, the gear portion 29 a takes a “neutral gear position” in which the through groove 35 is located on the movement movement path of the locking piece 21. For this reason, when the mandrel 25 pushes the interlock plate 12 downward when the steering wheel 4 is assembled to the vehicle body (the steering roll connector 1 and the steering column 24), the locking piece 21 of the interlock plate 12 passes through the groove. Pass 35. As a result, the interlock plate 12 is normally lowered, and the steering wheel 4 can be correctly assembled to the vehicle body.

  As shown in FIGS. 9A and 9B, it is assumed that the rotator 3 is rotated once in the arrow R1 direction (right direction) from the neutral position. At this time, since the first pushed portion 36a is located on the movement path of the switching protrusion 30, the switching protrusion 30 pushes the first pushed portion 36a in the rotation process, and the restricting portion 29 is an arrow in FIG. Rotate 1 notch in the R1 direction. As a result, the gear portion 29 a takes the “right one rotation position” in which the front side of the projecting piece 33 is positioned on the moving movement path of the locking piece 21. Therefore, since the locking piece 21 cannot pass through the gear portion 29a, the interlock plate 12 cannot be pushed down, and the steering wheel 4 cannot be assembled to the vehicle body in this state.

  As shown in FIG. 10A, when the rotator 3 is rotated once in the direction of the arrow R <b> 1 from the neutral position, the second pushed portion 36 b is positioned on the moving path of the switching protrusion 30. Therefore, as shown in the flow of FIG. 10 (a) → FIG. 10 (b), when the rotator 3 is rotated one more time in the direction of the arrow R1 (two rotations in total from the neutral gear position to the right), the rotation process Then, the switching protrusion 30 pushes the second pushed-in portion 36b, and further rotates the gear portion 29a by one notch. As a result, the gear portion 29 a takes a “right two rotation position” in which the rear side of the projecting piece 33 is positioned on the movement movement path of the locking piece 21. Therefore, since the locking piece 21 cannot pass through the gear portion 29a, the interlock plate 12 cannot be pushed down, and the steering wheel 4 cannot be assembled to the vehicle body even in this state.

  As shown in FIG. 11A, it is assumed that the rotator 3 is operated once in the direction of the arrow R2 (left direction) from the neutral position. At this time, since the first pushed portion 36a is located on the movement path of the switching protrusion 30, the switching protrusion 30 pushes the first pushed portion 36a in the rotation process, and the gear portion 29a is shown by the arrow R2 in FIG. Turn one notch in the direction. As a result, the gear portion 29 a takes a “left rotation position” in which the front side of the projecting piece 34 is positioned on the moving movement path of the locking piece 21. Therefore, the locking piece 21 cannot pass through the gear portion 29a, and the steering wheel 4 cannot be assembled to the vehicle body even in this state.

  As shown in FIG. 11 (b), when the rotator 3 is rotated one more time in the direction of the arrow R2 (two rotations in the left direction from the neutral gear position), the switching protrusion 30 is moved to the third pressed portion in the rotation process. 36c is pushed, and the gear part 29a is further rotated one notch. As a result, the gear portion 29 a takes a “left two rotation position” in which the rear side of the projecting piece 34 is positioned on the moving movement path of the locking piece 21. Therefore, since the locking piece 21 cannot pass through the gear portion 29a, the steering wheel 4 cannot be assembled to the vehicle body even in this state.

According to the configuration of the present embodiment, the following effects can be obtained.
(1) When the rotator 3 is in the neutral position of the rotation, the switching operation of the interlock mechanism 11 in the locked state to the unlock side is permitted by the assembly restriction mechanism 28. Can be assembled to the vehicle body. On the other hand, when the rotator 3 is not in the neutral position of the rotation, the switching operation to the unlock side of the interlock mechanism 11 in the locked state is not permitted by the assembly restriction mechanism 28, so that the steering wheel 4 is assembled to the vehicle body. However, the interlock mechanism 11 is not released, and the steering wheel 4 cannot be assembled to the vehicle body. Therefore, it is possible to further prevent the steering wheel 4 from being assembled to the vehicle body when the rotator 3 is not in the neutral position.

  (2) The assembly restriction mechanism 28 switches whether the steering wheel 4 can be assembled to the vehicle body depending on whether the interlock plate 12 can be operated to the unlock side according to the rotational position of the rotator 3. . Therefore, when the rotator 3 does not take the neutral position, the operation of the interlock plate 12 is restricted, that is, the movement of the interlock plate 12 is stopped so that the interlock mechanism 11 is not operated. Can be kept firmly locked.

  (3) When the through groove 35 of the restricting portion 29 is located on the movement path of the locking piece 21 of the interlock plate 12, the interlock plate 12 can be moved to the unlock side, and the rotator 3 can be moved from the neutral position. When the protrusions 33 and 34 of the restricting portion 29 are positioned on the movement path of the locking piece 21 by the switching protrusion 30, the operation of the interlock plate 12 to the unlock side becomes impossible. Therefore, the operation of the interlock plate 12 to the unlock side can be disabled by a simple configuration in which the movement of the locking piece 21 that is the lock portion of the interlock plate 12 is restricted by the restriction portion 29.

  (4) The restricting portion 29 is the gear portion 29a, and the operating position of the gear portion 29a is switched by the switching protrusion 30 turning the gear portion 29a while the rotator 3 makes one round from the neutral position. Therefore, when the operating position of the gear portion 29a (the assembly restriction mechanism 28) is switched, the gear portion 29a simply needs to move in its own position. Therefore, it is not necessary to increase the arrangement space of the parts required for the restricting portion 29, so there is no fear that the apparatus size will be increased.

  (5) The rotator 3 is configured to rotate a plurality of turns in both directions from the neutral position, and each time the rotator 3 makes one turn, the switching protrusion 30 selectively pushes one of the plurality of pushed parts of the gear part 29a. Thus, the gear portion 29a is moved by one notch each time the rotator 3 turns from the neutral gear position, and the operating position of the gear portion 29a is sequentially switched. Therefore, even if the rotator 3 has a structure in which the rotator 3 makes a plurality of turns in both directions from the neutral position, the interlock mechanism 11 can be prevented from being operated at each operating position.

Note that the embodiment is not limited to the configuration described so far, and may be modified as follows.
The interlock plate 12 is not limited to being pushed and displaced downward by the metal core 25 of the steering wheel 4, and may be pushed at any location of the steering wheel 4.

The number of the locking pieces 21 and the locking grooves 23 of the interlock mechanism 11 can be changed as appropriate.
The number of rotations of the rotator 3 is not limited to a total of 5 rotations of “2.5 laps” on the right and “2.5 laps” on the left with reference to the neutral position, but can be changed to other values.

  The structure in which the gear portion 29a is rotated by one notch in accordance with the rotation of the rotator 3 is appropriately changed to another structure as long as the gear portion 29a has a speed reducing mechanism that moves a predetermined amount with respect to one rotation of the rotator 3. Is possible.

The shape of the restricting portion 29 is not limited to a substantially plate shape in which two fan shapes are formed, and can be appropriately changed to various shapes.
The restricting portion 29 is not limited to the gear portion 29a that moves in its own position, and can be changed to a member that takes other motion, such as a slide member that reciprocates linearly.

  In restricting the movement of the interlock plate 12 by the assembly restricting mechanism 28, not only the restriction is realized by stopping the locking piece 21 by the restricting portion 29, but if it is a part of the interlock plate 12, The restriction may be realized by locking at any position of the throat.

The assembly restriction mechanism 28 may be formed anywhere as long as it is inside the steering roll connector 1.
The operation restriction of the interlock mechanism 11 to the unlock side by the assembly restriction mechanism 28 is not limited to being realized by stopping the movement of the interlock plate 12. For example, the operation of the interlock mechanism 11 toward the unlock side may be disabled by another method such as limiting the contraction of the plate urging unit 13.

  The interlock mechanism 11 is not limited to a structure including the interlock plate 12, the plate urging portion 13, and the sleeve 14, and the rotator 3 can be locked to the stator 2 before being assembled to the vehicle body. Any structure can be used as long as it is possible.

Next, technical ideas that can be grasped from the above-described embodiment and other examples will be described below together with their effects.
(A) In the steering roll connector, the assembly restricting mechanism restricts the operation of the interlock mechanism even when the interlock mechanism is unlocked when the rotator is not in the neutral position. As a result, the steering wheel cannot be assembled. According to this configuration, it is advantageous for preventing an erroneous assembly of the steering roll connector.
