However, the above-described conventional vehicle lever switch has a large number of constituent parts, a long assembly work time, and a structure in which a holder, a rotor, a moderation plate, and the like are stacked, and is small in size. However, it was difficult to implement the function, or because there was no space in the upper part of the shaft, the second and third switch devices could not be installed on the upper part of the shaft, making it difficult to achieve multiple functions.

The present invention solves the above problems, and it is an object of the present invention to provide a lever switch for a vehicle, which can be miniaturized by shortening the number of constituent parts, shorten the assembly work time, and can be multifunctional. And

[0006]

[Means for Solving the Problems]

 To achieve this object, the vehicle lever switch of the present invention has terminals formed on at least one of the same bottom surfaces of the holder and moderation ridges formed on the other side, and the opposite rotors correspond to the terminals of the holder. A movable contact is provided at a position, and a moderation generating member including a spring and a ball or a pin is inserted into a hole corresponding to the moderation crest portion.

[0007]

[Action]

 According to this configuration, the conventional moderation plate can be eliminated by forming the terminal for performing the switch switching operation and the moderation crest portion for providing a moderation feeling on the same bottom surface of the holder, thereby reducing the number of parts and reducing the cost. As a result, the assembly work time can be shortened and effective utilization can be facilitated as the internal space of the operating lever switch is expanded.

【Example】

 Hereinafter, a lever switch for a vehicle according to an embodiment of the present invention will be described with reference to the drawings.

First Embodiment FIG. 1 is a side sectional view of a vehicle lever switch according to a first embodiment, and FIG. 2 is a disassembled perspective view thereof.

In FIG. 1, reference numeral 1 denotes a knob base that serves as an operating lever for operating a switch device (not shown) for winkers for automobiles, and has a cylindrical hole 21 having a locking projection 21a at its center. There is. Reference numeral 2 is a shaft, and a split groove 20a provided below is inserted and fixed to a projection 21a inside the hole 21 of the knob base 1. Further, the shaft 2 is formed with grooves 19a, 19b for preventing the shaft from coming off and a split groove 20b extending in the axial direction from the tip to the center. Reference numeral 3 denotes a holder, which has a structure that can be mounted so as not to rotate by engaging the notch 3a with the locking projection 22 of the shaft 2. In the holder 3, for example, one terminal 23 in the shape of a fan and an annular terminal 24 in the inner periphery are installed on one of the same bottom surface (substrate surface) by insert molding or the like, and A moderation ridge portion 3b having a curved mountain shape having a convex portion and a concave portion is formed on the surface.

Reference numeral 4 denotes a rotor having a structure in which a disk-shaped part is provided with a cutout portion 4d that is cut out in a fan shape, and can be brought into contact with the wall surface 3c of the holder 3 to serve as a rotation stopper during a rotation operation.

The rotor 4 is provided with a movable contact 5 made of, for example, phosphor bronze and having a substantially bow shape on one side on the end face facing the holder 3 so as to be capable of elastically contacting the terminals 23 and 24 on the holder 3. It is provided. This movable contact 5 has five cut-and-raised parts 5a and 5b, the roots of which are fixed to the rectangular hole 4a for holding the rotor 4 and the projection 4b for positioning and heat staking. On the other side of the rotor 4 facing the movable contact 5, an insertion hole 4c for one steel ball 6 and one spring 7 as a moderation generating member is formed. By combining the rotor 4, the steel balls 6, the spring 7, the movable contact 5, and the holder 3, the two elastic claws 3d provided on the outer periphery of the holder 3 engage with the outer peripheral surface of the rotor 4 to form a unit. The converted first switch unit section 25 is configured. The steel ball may be made of resin, or may be a pin having a hemispherical tip, and the rotor 4 and the holder 3 may be configured in reverse.

Next, after inserting the first switch unit portion 25 into the shaft 2 and engaging the locking projection 22 of the shaft 2 with the notch portion 3a of the holder, a ring-shaped portion is formed to prevent the detachment. The retaining ring 9b of 1 is fitted and fixed in the groove 19b of the shaft 2. Reference numeral 8 denotes a movable knob having an engaging concave portion 8a on the inner peripheral portion thereof, and the engaging concave portion 8a is fitted and fixed to the outer peripheral convex portion 4e of the rotor 4. In this way, the shaft 2 to which the first switch unit portion 25 is fixed is inserted into the groove 20a of the protrusion 21a provided in the hole 21 of the knob base 1, and the ring-shaped retaining ring 9a is inserted into the groove 19a of the shaft 2. Engage and fix. The cover 26 is put on the opening of the knob base 1 and fixed with a screw 27. The cap 28 is put on the knob base 1 so as to house the shaft 2, and the pin 29 is used.

Next, the operation of the above embodiment will be described. In the above-described embodiment, the rotor 4 of the first switch unit portion 25 having a single switching circuit rotates in conjunction with the rotation operation of the movable knob 8, so that the steel ball 6 is placed on the holder 3 by the pressure of the spring 7. The detent ridge portion 3b is overcome to provide a detent feeling, and the fan-shaped notch portion 4d of the rotor 4 comes into contact with the wall surface formed on the holder 3 and stops. At the same time, as shown in FIGS. 3 (a) and 3 (b), the cut-and-raised portion 5b composed of two movable contacts 5 fixed to the rotor 4 is constantly in contact with the annular terminal 24 of the holder 3, and As shown in FIG. 3 (a), as shown in FIG. 3 (b), the cut-and-raised portion 5a composed of three pieces comes into contact with an insulating resin portion on the holder 3 where the terminal 23 does not exist, and is turned off as shown in FIG. The lamp is turned on when the cut-and-raised portion 5b is brought into contact with the fan-shaped terminal 23 on the holder 3 to switch to a switch-on state. When the reverse rotation operation is performed, the above operation is reversed and the lamp is turned off.

By thus providing the terminals 23 and 24 and the moderation crest portion 3b on the same bottom surface of the holder 3, the moderation plate which has been conventionally required can be eliminated, and the function of the switch can be similarly satisfied. The advantage is that you can.

In the above-described embodiment, the moderation crest portion 3b is formed integrally with the holder 3, but the material of the moderation crest portion 3b is the same as the material of the holder 3 in order to improve the sense of moderation during the rotating operation. When different types must be used, or when multiple operating angles and operating loads must be handled as variations, the moderation peaks can be made of different materials or different shapes as shown in Fig. 4. It is also possible to fit the plate 30 as a piece during assembly.

(Embodiment 2) FIG. 5 shows a second embodiment of the present invention, which is one of the terminals 23, 24 of the holder 3 in the first switch unit portion 25 of the first embodiment. Instead, the variable resistor unit 32 is mounted with the resistor substrate 31 on which the printing resistor 33 is formed and which can change the resistance by contact with the movable contact 5. This structure also eliminates the need for a moderation plate that was previously required on the top of the rotor, and has the effect of reducing costs due to the reduction in the number of parts, shortening assembly time, and ensuring an empty space in the operating lever. .

[0018]

[Effect of device]

 As is apparent from the above description, the present invention can eliminate the conventional moderation plate by forming the terminals and moderation peaks on the same bottom surface of the holder, and reduce the cost by reducing the number of parts. In addition, the second and third switch units can be easily configured in an extra space in the vehicle lever switch, which has the effects of shortening the assembly work time and the like, and is multifunctional by making the switch unit compact. It also has the effect of being able to.
