BACKGROUND OF THE INVENTION
The present invention relates to a vehicle combination switch (hereinafter, referred to as a combination switch) including a lever-operated light control switch unit, a wiper control switch unit, and the like mounted on a steering column of an automobile.
[0002]
[Prior art]
The prior art will be described with reference to FIGS.
[0003]
FIG. 3 is a partial sectional view of a conventional combination switch, and FIG. 4 is an exploded perspective view.
[0004]
1 In the figure denotes an operating lever for operating the combination switch, at its front end portion 1A is incorporated a write control switch 11 to be the first switch is inserted into the opening 4A of the one end portion of the slide 4 The bottom portion 1B has an operation surface 1C of a dimmer / passing switch 10B serving as a second switch on the lower surface, and further, a hole portion 1D is formed at the tip thereof, and a moderation spring 2 and a roller 3 are disposed, The spring pin 5 inserted from the through hole 4B on the side surface of the sliding body 4 is passed through the through hole 1E of the operation lever 1, and the operation lever 1 is held so as to be rotatable in the vertical direction with the spring pin 5 as a fulcrum. .
[0005]
Further, the operation lever 1 has a cylindrical fulcrum shaft 4C, 4D formed on the lower surface and the upper surface of one end of the sliding body 4, and a bearing portion 6A of a circular recess formed on the bottom surface of the opening of the case 6. By being fitted to bearing portions 7A of circular recesses formed on the lower surface of the cover 7 that covers the case 6 in which the sliding body 4 is incorporated, it is held so as to be rotatable in the front-rear direction.
[0006]
Further, a moderation mountain 4E is formed on the contact surface of the roller 3 at the tip of the base portion of the operation lever 1 in the opening 4A of the sliding body 4, and constitutes a moderation lock portion when the operation lever 1 is operated in the vertical direction. Further, a moderation spring 8 and a pin 9 are arranged in the hole 4F at the tip of the other end, and the moderation mountain 6B on the inner contact surface of the opening of the case 6 is used when the operation lever 1 is operated in the front-rear direction. The moderation lock part is configured.
[0007]
Further, on the lower surface of the case 6, the turn signal switch 10A serving as the third switch, and a second dimmer passing switch 10B becomes switch and the connector portion 10C of the light control switch 11 serving as a first switch, these A terminal board 10 integrally formed with an external connector part 10D is mounted.
[0008]
A plurality of lead wires 12 with terminals extended in order to transmit an electric signal generated by opening / closing the light control switch 11 serving as the first switch to the vehicle side includes a gap portion 1F of the operation lever 1 and a sliding body 4. After passing through the opening 4 </ b> A, the opening 6 </ b> C on the lower surface of the case 6, and the groove 10 </ b> E of the terminal plate 10, it is connected to one connector 13 and attached to the connector portion 10 </ b> C of the terminal plate 10.
[0009]
Next, the operation of this combination switch will be described.
[0010]
When the operation lever 1 is turned up and down, the lower operation surface 1C moves up and down with the spring pin 5 of the sliding body 4 as a fulcrum to open and close the dimmer / passing switch 10B serving as a second switch .
[0011]
Then, when the operation lever 1 is rotated in the front-rear direction, the operation lever 4 operates in the front-rear direction with the operation protrusion 4G on the lower surface of the other end about the fulcrum shafts 4C, 4D of the sliding body 4 as a fulcrum . The turn signal switch 10A serving as a switch is opened and closed.
[0012]
Further, a light control switch 11 serving as a first switch provided at the distal end portion 1A of the operation lever 1 is opened and closed by directly operating it, and a terminal board for transmitting an electric signal generated by opening and closing each switch to the vehicle side. It is sent to each function on the vehicle side from 10 connector portions 10D.
[0013]
[Problems to be solved by the invention]
However, in the conventional combination switch described above, when the operation lever 1 having the light control switch 11 built in the distal end portion 1A is incorporated in the switch body, the connector 13 to which the lead wires 12 having a plurality of terminals of the light control switch 11 are connected is slid. Although it is necessary to pass through the opening 4A of the moving body 4, the opening 4A having a size through which the connector 13 passes cannot be provided. Therefore, after the lead wires 12 having a plurality of terminals are passed through the opening 4A of the sliding body 4, There is a problem that the work of attaching to the connector 13 and attaching to the connector portion 10C of the terminal board 10 is required and the production efficiency cannot be improved.
[0014]
An object of the present invention is to improve the assembly workability of such a combination switch.
[0015]
[Means for Solving the Problems]
In the combination switch of the present invention, a first switch having a built-in first switch at the tip and having a second switch operation portion at the root, and a first opening formed at one side surface of the operation lever root. A sliding body that is inserted into the part and holds the operating lever that can operate the second switch provided below the base of the operating lever so as to be pivotable in the vertical direction, and the other lower side of the sliding body A case and a cover, which is configured to be capable of operating a third switch provided on the control unit so as to be rotatable in the front-rear direction together with the operation lever, a gap in the operation lever, and a lower surface of the slide body. The first opening formed on one side surface of the sliding body, comprising a lead wire having one end connected to the first switch and the other end connected to the connector. A cylindrical rotating shaft divided by a split groove into which the lead wire communicating from one side surface of the sliding body to the second opening can be inserted is formed on the lower surface. The above-mentioned case is provided with a bearing portion of a ring-shaped recess that is fitted and held on the inner and outer periphery so as to be rotatable .
[0016]
Therefore, according to the present invention, the lead wires with a plurality of terminals previously connected to the connector in the previous process are easily passed through the sliding body in the completed assembly process, thereby reducing the number of assembly steps and improving the work efficiency. Can be provided and an inexpensive combination switch can be provided.
