Description

[Detailed explanation of the idea] [Industrial application field]

The present invention provides a roll connector for temporarily fixing each member of the rotor and stator, which constitute the roll connector as an electrical connection device between a vehicle handle and a steering column, at the neutral position of the coil tape stored inside the roll connector. This relates to a temporary fixing device.

[Conventional technology]

Devices for making electrical connections between the steering wheel and steering column of automobiles generally include:
Roll connectors are used. This roll connector is composed of a rotor whose casing rotates together with the steering wheel, and a stator that is fixed to the steering column. It also contains a spirally wound coil tape. One peripheral end of the coil tape is fixed to the rotor, and the other peripheral end is fixed to the stator. The roll connector has this configuration because the coil tape follows the rotation of the steering wheel while loosening and tightening its spiral state, thereby enabling electrical connection between the steering wheel and the steering column. This is because the purpose is to In addition, before the roll connector is installed in a car, the rotor and stator are naturally rotatable relative to each other, and furthermore, the coiled state of the coil tape stored inside the rotor is dependent on the rotation between each member. It changes arbitrarily accordingly. If the spiral state of the coil tape is neither tightened nor loosened, it is defined as its neutral state, and the state of the steering wheel when the car is traveling straight is defined as its neutral state. Depending on the mounting state, such as when the coil tape is mounted in a non-neutral state, the coil tape may not be able to fully follow the rotation of the handle. In such a case, there are problems such as the handle not being able to be rotated or the coil tape being cut. Conventionally, as a means for solving this problem, there is a method in which positioning holes are provided at predetermined locations on the rotor and stator, and pins are inserted into and removed from the holes to temporarily fix and release the fixing. In addition, there are some devices in which temporary fixing is performed by pasting a temporary fixing sticker across each member.

[Problem that the idea aims to solve]

Among these, when a roll connector temporarily fixed with a pin is installed in an automobile, it is necessary to remove the pin after installation in order to enable rotation of the steering wheel. However, the steering column cover gets in the way during this work, and there is not enough work space. Therefore, the work itself has become extremely troublesome, and furthermore,
There is also the risk of losing the pin during this work. In addition, for items that are temporarily attached using a seal, the release of the temporary attachment is performed by cutting the seal itself, so when the roll connector is removed and reinstalled for repairs etc., it is necessary to remove the temporary attachment from the parts that were initially attached. Not reproducible. Furthermore, with any of these means, there is a problem in that another part must be prepared for temporary fixing. The present invention was devised to solve the above-mentioned problems. Therefore, its purpose is
Provided is a temporary fixing device for a roll connector that can easily temporarily fix and release the rotor and stator constituting the roll connector, eliminates the risk of losing the parts, and has reproducibility of temporary fixing and release. It's about doing.

[Means and actions to solve the problem]

The roll connector temporary fixing device according to the present invention is
In order to achieve the above purpose, the system is configured as follows. That is, in the roll connector temporary fixing device according to claim 1, either one of the rotor and the stator that constitutes the roll connector casing has a flexible tongue-like shape that protrudes outward from the casing. It has an integral body. This tongue-shaped body has a distal end portion that is a locking portion that is formed wide relative to the base portion, and is also capable of contracting and deforming. For this purpose, for example, the tip portion may be formed into two forks, or may be formed from a material such as rubber. The other member of the rotor and stator is provided with an engagement hole that allows the base of the tongue to be inserted therethrough, while restricting the insertion of the distal end locking portion of the tongue. In other words, the hole is sized to be located midway between the distal end locking portion and the base of the tongue. In this way, the tongue-like body is
It is configured such that it can be inserted into and removed from the engagement hole by contracting the distal end locking portion. In the above configuration, when the tongue-shaped body is bent at its base and pushed into the engagement hole, if the distal end locking portion remains in a free state, the tongue is wider than the engagement hole, which prevents its insertion. By pushing it in even more strongly, the locking portion is pressed by the wall surface constituting the hole, shrinks and deforms, and is inserted into the inside of the hole.
Then, the wall surface that is located around the locking part and presses the locking part comes to be located around the base of the tongue-like body, so that the locking part is released from the pressing force and is again pressed. Return to original size. In this state, even if the tongue is pulled outward from the engagement hole, the locking portion thereof will be caught in the hole and will not easily come out. That is, in this state, the rotor and stator are temporarily fixed, and by keeping the coil tape in a neutral spiral state as described above, the roll connector can be easily and reliably attached. Moreover, after it is attached, the temporary fixation can be released by turning the handle forcefully. This temporary fixing is released as follows. First, as the handle rotates, the proximal end or locking portion of the tongue moves in the rotational direction of the rotor. By turning more strongly, the locking portion and the base portion are pulled and twisted by the bent portion of the tongue. If the tongue is turned further, the locking part of the tongue is pressed against the wall constituting the engagement hole, shrinks and deforms, and is drawn into the engagement hole.Furthermore, the tongue is pulled out from the engagement hole again. Protrudes outward from the casing. That is, the temporarily fixed state between the rotor and the stator is released. Further, in the roll connector temporary fixing device according to claim 2, one of the rotor and the stator is integrally formed with a flexible material so as to protrude outward from the casing. A tongue-like body is provided, and the other member is integrally provided with an engagement protrusion that engages with the tongue-like body. The engagement protrusion has, for example, a spherical distal end and a rod-like base having a smaller diameter than the distal end. The tongue-shaped body is provided with an engagement hole that allows the base of the engagement protrusion to be inserted therethrough, while restricting the insertion of the tip thereof. That is, a hole is provided that is larger than the base of the engagement protrusion and smaller than the tip. In addition,
It is preferable to provide several small notches around this engagement hole. When temporarily fixing the rotor and stator members in the above configuration, first, the tongue-shaped body is bent at its base to bring the surrounding portion of the engagement hole into contact with the engagement protrusion. When the tongue-shaped body is pushed in more strongly, the engagement protrusion is inserted into the engagement hole while the periphery of the engagement hole is deformed so as to be bent in the insertion direction of the engagement protrusion. When the insertion of the engagement protrusion is completed, the deformed portion around the engagement hole returns to its original shape. Here, since the base of the engagement protrusion can be freely inserted into the engagement hole, the tongue-like body also tries to return to its natural state of protruding outward from the casing, but the tip of the engagement protrusion Once the surrounding portion of the engagement hole is caught, the tongue-shaped body will not easily come off. Moreover, after this roll connector is installed in a car, like the roll connector according to claim 1,
The temporary lock can be released by turning the handle forcefully. This temporary fixing is released as follows. That is, first, the tongue-like body is pulled so as to be twisted as the rotor rotates. If it is turned further, the portion around the engagement hole deforms in the same way as when it is temporarily fastened, and the tip of the engagement protrusion is drawn into it. Furthermore, the engagement protrusion is removed from the engagement hole, and the tongue-like body projects outward from the casing again. In this way, the temporarily fixed state is released.

【Example】

An embodiment of the roll connector locking device according to claim 1 will be described below with reference to FIGS. 1 and 2. FIG. 1 is a plan view of one embodiment of a temporary fixing device for a roll connector according to claim 1, and FIG. 2 is a sectional view thereof taken along the line -2. As shown in the figure, the casing 3 of the roll connector applied to this example is
It consists of a rotor 1 attached to a member on the steering wheel side and a stator 2 attached to a steering column. The rotor 1 constitutes an inner circumferential wall 1b of the casing 3, and the stator 2 constitutes an outer circumferential wall 2a, an upper wall 2b, and a bottom wall 2c of the casing 3, respectively. A spirally wound coil tape 4 is stored in a roughly donut-shaped space created by combining the outer circumferential wall 2a and upper wall 2b of the stator 2 with the rotor, and a lid is closed using the bottom wall 2c. do. With this configuration, the rotor 1 is held between the stator 2 and is rotatable relative to the stator 2. Although not shown, the coil tape 4 has its inner peripheral end and outer peripheral end connected to the contact terminals of the rotor 1 and stator 2, respectively. In order to maintain the coiled state of the coil tape 4 in a neutral state (not too tight or too loose), engagement holes 6 and tongue-shaped A body 5 is provided. This tongue-shaped body 5 is made of flexible resin and is attached to the stator 2 so that it protrudes outward from the stator 2 when no external force is applied.
It is formed integrally with the outer peripheral wall 2a of. Also,
Its cross-sectional shape is substantially flat, and by aligning the direction of its thickness d with the axial direction of the steering shaft, it can be easily flexible in the axial direction. Further, as shown in the figure, the tip portion 5
A has a step part 5c which is wider than the base part 5b, and the central part thereof is cut out to form a bifurcated shape. Note that the bifurcated portion is formed so that the width a becomes somewhat narrower toward the tip. On the other hand, a retainer 1a having an outer circumferential wall 1c located on an extension of the outer circumferential wall 2a of the stator 2 is attached to the rotor 1 with screws 7, and an engagement hole 6 is provided in the outer circumferential wall 1c. The engagement hole 6
is, than the cross-sectional shape of the base 5b of the tongue-like body 5,
Both the width c and the thickness e are made into a slightly larger substantially rectangular shape, but the width c is smaller than the width a of the distal end locking portion of the tongue-shaped body 5. Further, the tongue-like body 5 and the engagement hole 6 are provided on the stator 2 and the rotor 1, respectively, so that the coil tape 4 is parallel to the axial direction of the steering shaft when the coil tape 4 is in the above-mentioned neutral state. There is. From this state, the tongue-like body 5 is removed from its base 5b.
A case in which it is bent and inserted into the engagement hole 6 will be explained. First, the tip locking portion 5a of the tongue-like body 5
is formed into a tapered shape so that the width becomes narrower toward its tip, so it is inserted into the engagement hole 6 at the earliest stage, but eventually the engagement hole 6 is inserted into the engagement hole 6.
The width c of the tongue-like body 5 and the width of the locking portion 5a of the tongue-shaped body 5 interfere with each other at the same portion. In this case, the engagement hole 6
On the other hand, the locking portion 5a of the tongue-shaped body 5 located on the rear side of insertion is shaped to gradually become larger than the engagement hole 6. Therefore, if the tongue-like body 5 is pushed further, the locking portion 5a of the tongue-like body 5 will be
The wall surface forming the engagement hole 6 and the tapered locking portion 5a of the tongue-like body 5 are mutually connected to each other while deforming so that the outer shape becomes smaller by bending so that the bifurcated portions approach each other. slide. In this state, the locking portion 5a of the tongue-shaped body 5 is pressed against the wall surface forming the engagement hole 6 so as to be sandwiched therebetween. When the tongue-shaped body 5 is further pushed in, the insertion operation is completed when the stepped portion 5c passes through the wall surface of the engagement hole 6. This state is shown by imaginary lines in FIG. 2, and since no external force is applied to the area around the locking portion 5a of the tongue-like body 5, the locking portion 5a returns to its natural state. . Since the base portion 5b of the tongue-like body 5 can be freely inserted into the engagement hole 6, the tongue-like body 5 itself returns to its original shape, that is, the state in which it protrudes outward from the casing, by a so-called spring action. try to. However, the locking portion 5 of the tongue-like body 5 that has returned to its natural state
a is caught in the engagement hole 6, and the tongue-shaped body 5 does not easily come out from the engagement hole 6. Therefore, by using the roll connector temporarily fixed in this way, the neutral state of the roll connector and the neutral state of the handle can be easily and reliably matched. Further, after the roll connector and handle are attached, the temporary fixing can be released by simply turning the handle forcefully, that is, without any troublesome work. First, if you turn the handle a little, the tongue-like body 5
The locking portion 5a moves as the engagement hole 6 rotates. And the base 5 of the bent tongue-like body 5
The locking portion 5a is pulled from the stator 2 by twisting b. When turned further, the locking portion 5a
The two forked portions of the engaging hole 6 deform as they approach each other, and the width of the stepped portion 5c becomes smaller.
drawn inside. Furthermore, the tongue-shaped body 5 is pulled out from the engagement hole 6, and then protrudes outward from the casing again as shown in FIG. Therefore,
The rotation of the rotor 1 is no longer restricted by the stator 2, and the temporary fixing of each member is completely released. Further, an embodiment of the roll connector according to claim 2 will be described below with reference to FIGS. 3 and 4. FIG. 3 is a plan view of one embodiment of the roll connector temporary fixing device according to claim 2, and FIG. 4 is a sectional view thereof taken along the line -2. As is clear from the figure,
Since the main structure of the roll connector is completely the same as the embodiment according to claim 1, detailed explanation will be omitted. In this embodiment, an engaging protrusion 11 is provided on the outer peripheral wall 1c of the rotor 1. This engagement protrusion 11 is composed of a spherical tip 11a and a rod-shaped base 11b having a smaller diameter than the tip 11a. Also,
The tongue-shaped body 10 provided on the stator has an engagement hole 10 in its tip 10a which has a smaller diameter than the tip 11a of the engagement protrusion 11 and a larger diameter than the base 11b.
C is open. Further, a notch 10d is formed at a position facing the circumferential portion of the engaging hole 10c. When temporarily fixing the roll connector configured in this way, first bend the tongue-shaped body 10 at its base 10b, and position it so that the area around the engagement hole 10c contacts the tip 11a of the engagement protrusion 11. let If the tongue-like body 10 is pushed into the rotor 1 side as it is, the portion of the engagement protrusion 11 that is in contact with the tip 11a tends to remain in that position, so that the tongue-like body 10 splits into two at the notch 10d. It deforms as if it were folded into. When pushed in further, the notch 10d widens and the engagement hole 10c itself deforms to become larger. The tongue-like body 10 is
With such deformation, the engaging protrusion 11 is inserted into the engaging hole 10c. This state is shown in phantom lines in FIG. At this time, the engaging protrusion 1
Since the base portion 11b of the tongue member 10 can be freely inserted into the engagement hole 10c, the deformed tip portion 10a of the tongue-like body 10 returns to its original planar state. In addition, the tongue-like body 10
tries to return to the natural state of protruding outward from the casing due to the spring action of the base 10b, but the portion around the engagement hole 10c
It gets caught in 1a and does not come off easily. Furthermore, after attaching the roll connector and handle, the temporary attachment can be released by simply turning the handle forcefully. First, by turning the handle a little, the tip 10a of the tongue-shaped body 10 moves as the engagement protrusion 11 rotates. Then, the bent tongue-like body is twisted and pulled. When the engagement hole 10c is further turned, the engagement hole 10c deforms in the same way as when temporarily tightening, and the tip portion 11 of the engagement protrusion 11 is inserted inside the engagement hole 10c.
a is drawn in. Furthermore, the engagement protrusion 11 is disengaged from the engagement hole 10c, and thereafter the tongue-like body 10 projects outward from the casing. Therefore, the rotation of the rotor 1 is no longer restricted by the stator 2, and the temporary fixing of each member is completely released.

【effect】

As explained above, according to the roll connector temporary fixing device according to the present invention, the rotor and the stator can be easily temporarily fixed and released without preparing any parts other than the roll connector components, and The temporary fixing and release are reproducible.
