【Example】

 An embodiment of a lever switch mounting structure according to the present invention will be described in detail below with reference to FIGS. 1, 2, 3 and 4.

Reference numeral 1 is a lever switch installed on a steering column (not shown) of an automobile. The lever switch 1 is, for example, a combination switch having the functions of an intermittent wiper washer switch and a rear wiper washer switch. Reference numeral 2 is an operation lever. The operating lever 2 has a shaft 2a integrally formed at one end, and a moderation pin 4 biased by a spring 3 is inserted at the other end. The operating lever 2 swings in the directions of arrows A and B by pivotally supporting the shaft portion 2b on elastic bearing portions 5a and 5b formed on both side surfaces of the movable platen 5. The operation lever 2 has protrusions 2c and 2d formed on the upper surface and the lower surface in the vicinity of the shaft portion 2b. The operation lever 2 is provided with a rear wiper switch 6 and an intermittent wiper volume 7 at the tip on the side of the shaft 2a. A cord 8 is inserted through the operation lever 2. When the operation lever 2 is operated in the arrow A direction, the operation lever 2 swings in the arrow A direction around the shaft portion 2b. Then, the operation lever 2 pushes down the movable contact piece 12, the movable contact piece 12 comes into contact with the fixed contact 13, and the washer switch is turned on. When the operating lever 2 is operated in the directions of arrows C and D, the operating lever 2 swings together with the movable plate 5 about the shaft portions 5c and 5d. The protrusions 2c and 2d are formed to prevent rattling of the operating lever 2 in the vertical direction, and the tips of the protrusions 2c and 2d are arcuate in order to improve the slidability. The protrusions 2c and 2d contact the upper surface and the lower surface of the insertion hole 5e. When the movable platen 5 rotates, the movable contact 11 comes into contact with the fixed contact 14 and the intermittent wiper switch is turned on. The movable plate 5 is inserted into an opening 9a formed on the side surface of the switch body 9. The movable platen 5 pivotally supports shaft portions 5c and 5d on elastic bearing portions 9b and 9c formed on the upper and lower surfaces of the opening 9a. The movable platen 5 is provided with a movable contact 11 of an intermittent wiper switch via a spring 10. The movable platen 5 has an insertion hole 5e on the side surface for inserting the tip portion of the operation lever 2. Further, the movable platen 5 has a hole 5f formed in the lower surface thereof so that the curved portion 12a of the movable contact piece 12 is brought into pressure contact with the operation lever 2. The elastic bearing portions 5a and 5b have elasticity due to the cutout portions 5f and 5g formed in the movable platen 5. The switch body 9 is installed on a steering column (not shown). The switch body 9 has a movable contact piece 12, fixed contacts 13 and 14, and a board 16 on which electronic components 15 are mounted side by side on the lower surface. The elastic bearing portions 9b and 9c have elasticity by the cutout portions 9d and 9e formed in the switch body 9.

The assembly structure of the lever switch according to the present invention is configured as described above, and the assembly procedure will be described in detail below.

When assembling the lever switch 1, first, the rear wiper switch 6 and the volume 7 are attached to the operation lever 2. Then, the cord 8 is inserted into the operation lever 2. The moderation pin 4 is inserted into the tip of the operation lever 2 via the spring 3. Then, the operation lever 2 is inserted into the insertion hole 5e of the movable plate 5. The shaft portion 2b is pivotally attached to the elastic bearing portions 5a and 5b, and the operating lever 2 is pivotally supported in the directions of arrows A and B. The movable plate 5 is inserted into the opening 9a. Then, the shaft portions 5c and 5d are engaged with the elastic shaft receiving portions 9b and 9c, so that the movable plate 5 and the operating lever 2 are pivotally supported in the directions of arrows C and D. The assembly of the lever switch 1 is completed by inserting the spring 10 and the movable contact 11 into the movable plate 5 and installing the substrate 16 in the switch body 9.

As described above, the operation lever 2 of the present invention can be assembled to the movable plate 5 only by inserting it into the insertion hole 5e of the movable plate 5, and the number of assembling steps and the number of parts can be reduced. Can be reduced. Further, the movable plate 5 of the present invention can be assembled to the switch main body 9 only by inserting the movable plate 5 into the opening 9a of the switch main body 1, and the number of assembling steps and the number of parts can be reduced.

Next, the operation of the assembly structure of the lever switch according to the present invention will be described in detail.

When the operating lever 2 is operated in the direction of arrow A, the operating lever 2 swings around the shaft portion 2b. At this time, the protrusions 2c and 2d slide on the upper surface and the lower surface in the insertion hole 5e. The operation lever 2 is prevented from rattling in the vertical direction by the protrusions 2c and 2d, and is prevented from rattling in the lateral direction by the moderation pin 4 urged by the spring 3. When the operation lever 2 swings in the direction of arrow A, it pushes down the movable contact piece 12. Then, the movable contact piece 12 contacts the fixed contact 13, and the washer switch is turned on.

When the operating lever 2 is operated in the direction of arrow C or D, the operating lever 2 swings around the shaft portions 5c and 5d. Then, the movable contact 11 contacts the fixed contact 14 to turn on the intermittent wiper switch.

As described above, an example of the intermittent wiper washer switch installed on the right side of the switch body 9 has been described in detail as an example of the lever switch assembly structure according to the present invention. It can also be used in a turn signal switch or the like.

[0017]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. In the assembly structure of the lever switch according to claim 1, since the operation lever integrally formed with the shaft portion can be pivotally supported on the elastic bearing portion of the movable plate with one touch, the number of parts and the assembly man-hour can be reduced. Therefore, the cost can be reduced. Further, according to the first aspect, since the protrusion that abuts the inner wall of the insertion hole of the movable plate is formed in the vicinity of the shaft portion of the operation lever, it is possible to prevent the operation lever from rattling. In the lever switch assembly structure according to the second aspect of the present invention, the movable plate can be pivotally supported in the opening on the side surface of the switch body with one touch, so that the assembly man-hour and assembly time can be reduced and the number of parts can be reduced. .
