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. The roll connector has a casing made up of a rotor that rotates together with a steering wheel, and a stator that is fixed to a steering column.
A highly flexible coil tape, which is formed into a band shape by integrally covering a plurality of conductors, is housed inside the tape in a spiral manner. Furthermore, one peripheral end of this coil tape is fixed to the rotor, and the other peripheral end is fixed to the stator. The reason why the roll connector is configured like this is that the roll connector follows the rotation of the steering wheel while loosening and tightening the coiled state of the coil tape, thereby establishing an electrical connection between the steering wheel and the steering column. This is because the purpose is to make it possible. Therefore, 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 and stator is controlled by the rotation between each member. It changes arbitrarily with the movement. Here, 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 with respect to the neutral state of the handle, the coil tape may not be able to fully follow the rotation of the handle. In such a case, problems such as the inability to rotate the handle and the risk of cutting the coil tape arise. Therefore, as a means to solve such problems,
Conventionally, positioning holes are provided at predetermined locations on the rotor and stator as means for engaging the pins, and temporary fixing and release are performed by inserting and removing temporary fixing pins into the holes. is used.

[Problem that the idea aims to solve]

On the other hand, after the roll connector is installed in the automobile, the temporary fixation must be easily released due to work space constraints. Therefore, in the conventional temporary fixing device for a roll connector, the pin itself is easily removed from the casing. However, because of this structure, the pins sometimes fell out before being attached to the car, making it impossible to maintain consistency with the steering wheel. Therefore, when installing it, it was necessary to be careful not to pull out the pin. The present invention has been devised to effectively solve the problems of the prior art as described above. Therefore, the purpose of the roll connector is to ensure that the roll connector is temporarily secured in the neutral position so that it will not be released inadvertently, and that the roll connector can be easily released when the temporary release is necessary. An object of the present invention is to provide a temporary fixing device.

[Means 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, it consists of a temporary fixing pin and each engagement means formed to attach and lock the temporary fixing pin to each of the rotor and stator.
Either one of the engagement means has an insertion space into which the temporary fixing pin is inserted, and a slit that communicates the insertion space with the outside of the engagement means. Further, the temporary fixing pin is inserted through the slit when the temporary fixing pin is attached, and has a protrusion that protrudes from the engaging means to the outside. Further, a temporary fixing seal is stuck to one of the temporary fixing means described above, in a state where the temporary fixing pin is attached, so as to span the slit on the pin pulling-out side rather than the protrusion.

[Effect]

In the above configuration, the temporary fixing pin is attached to the casing while the protrusion formed on the pin passes through the slit provided on one side of the engaging means.
When the mounting is completed, the temporary fixing pin is engaged with each engagement means formed on the rotor and the stator. Therefore, the rotor and stator do not rotate relative to each other, and are prevented from rotating. At this time, a protrusion formed on the pin protrudes from the engagement means provided with the slit.
Even if a force is applied to the pin that causes it to fall off due to carelessness when installing it in a car, the protrusion formed on the pin will catch on the temporary seal that is pasted across the slit. The temporary fixing pin will not accidentally fall out from the casing. On the other hand, if you want to release the temporary fixing after installing a roll connector in a car, if you forcibly pull out the temporary fixing pin, the protrusion provided on the temporary fixing pin will cut the temporary fixing seal, and the temporary fixing pin will be removed. The pin is easily removed from the casing and the temporary fixation is released.

【effect】

According to the above configuration, temporary fixing of the roll connector at the neutral position is ensured. In other words, the temporary attachment will not be released due to careless attachment to the vehicle. Further, when necessary, the temporary fixing can be easily released by pulling out the temporary fixing pin forcefully.

[Embodiment] A temporary fixing device for a roll connector according to an embodiment of the present invention will be described in detail below with reference to FIGS. 1 to 3. FIG. 1 is a perspective view of a roll connector to which a temporary fixing device according to the present invention is applied, FIG. 2 is a perspective view of a temporary fixing pin, and FIG. 3 is a perspective view of a temporary fixing seal. In FIG. 1, reference numeral 1 indicates a rotor that is attached to the handle and rotates together with the handle (not shown). This rotor 1 is formed with a pin 7 that protrudes from its upper surface.
When the rotor 1 is installed, it engages with a pin hole formed in the member on the handle side, and the rotor 1 and the handle rotate integrally. Further, reference numeral 2 indicates a stator that is screwed to a member on the steering column side through a fixing portion 2a. Although details are not shown, the rotor 1 and stator 2 are rotatably combined with each other, thereby forming a casing 10 that defines a donut-shaped space therein. Furthermore, although this is not shown, inside the casing 10, a highly flexible coil tape, which is formed into a band shape by integrally covering a plurality of conductors, is housed in a spirally wound manner. ing. The coil tape has its inner peripheral end and outer peripheral end connected to the contact terminals of the rotor 1 and the stator 2, respectively. As described above, before the roll connector is mounted on the automobile, the rotor 1 and stator 2 are rotatable relative to each other, and the spiral state of the coil tape changes arbitrarily as the rotor 1 and stator 2 rotate. Therefore, in order to maintain consistency with the handle when installed, the spiral state of the coil tape should be in a neutral state (not too tight or too loose).
In order to maintain this, a rotation stopper 5 is formed on the rotor 1 and a pin holding portion 6 is formed on the stator 2 as means for engaging the temporary fixing pin 3. As shown in the figure, the temporary fixing pin 3 has a main body made of a T-shaped member in cross section, and has a protrusion 3a formed at its insertion side end and a knob 3c at its withdrawal side end. In addition, an insertion stopper 3b is formed on the back surface of these with the same width as the T-shaped member. The pin holding portion 6 formed on the stator 2 has two opposing pin holding portions so that the T-shaped temporary fixing pin 3 is housed therein.
It is composed of two L-shaped members, and a slit 6a is formed between the L-shaped members. Note that the amount of protrusion of this L-shaped member with respect to the stator 2 is approximately the same as the thickness t of the T-shaped member that is the main body of the temporary fixing pin 3. On the other hand, a rotation stopper 5 formed on the rotor 1
is composed of two protrusions formed at a distance equal to the width of the temporary fixing pin 3 so as to sandwich the insertion stopper 3b of the temporary fixing pin 3 from both sides. In the temporary fixing device configured as described above, the temporary fixing pin 3 is attached to the pin holding portion 6 of the stator 2 while being guided by the slit 6a.
At this time, the insertion stopper 3b formed on the back surface comes into contact with the upper surface of the rotor 1, and the temporary fixing pin 3
is positioned in the insertion direction. Furthermore, rotation stoppers 5 are provided on both sides of this insertion stopper 3b.
is positioned to prevent rotation between the rotor 1 and stator 2. In this state, the protrusion 3a formed on the temporary fixing pin 3 protrudes from the pin holding portion 6. Then, a temporary seal 4 is attached to the pin holding portion 6 at the pull-out side portion of the protrusion 3a, spanning the slit 6a. This temporary fixing seal 4 acts to prevent the temporary fixing pin 3 from coming off, and the pin 3 is fixed in cooperation with the above-mentioned insertion stopper 3b. Here, the temporary seal 4 has an adhesive part 4b located on both sides thereof, and a connecting part 4 having a narrower width than the adhesive part 4b.
It is composed of c. Furthermore, a notch 4a such as a perforation is made in the center of the connecting portion 4c. And, as shown in Figure 1,
The temporary fixing seal 4 is attached such that the notch 4a thereof is located adjacent to the protrusion 3a of the temporary fixing pin 3. As already mentioned, temporary seal 4
Normally, the temporary fixing pin 3 is prevented from coming off, but when the temporary fixing pin 3 is forcibly pulled out with a certain force or more, the protrusion 3a causes the notch 4 to be removed.
a is cut. Therefore, it becomes possible to pull out the temporary fixing pin 3 while being guided by the slit 6a as in the case of mounting. As explained above, according to the above configuration, the roll connector is reliably temporarily fixed at the neutral position, and the temporary fixing is not inadvertently released when the roll connector is attached to an automobile. On the other hand, when necessary, by pulling out the temporary fixing pin forcefully,
You can easily release the temporary fix. Note that the present invention can be implemented in various other ways. For example, the temporary fixing pin may have a cylindrical shape and the protrusion may be formed at the center of the pin instead of at its tip.
In that case, the pin holding portion is formed into a cylindrical shape without a slit, and the rotation stopper is formed to protrude from the side surface of the rotor. With this configuration, the temporary fixing pin is installed with the protrusion coming into contact with the pin holding portion while passing through the rotation stopper. If a rotation stopper is formed so that a temporary seal can be attached to a portion closer to the pin withdrawal side than the protrusion, exactly the same effect as in the above-mentioned embodiment can be obtained.
