[Detailed description of the invention] The present invention relates to a mounting structure for electrical components suitable for mounting electrical components on a switch base fixed to a steering column of an automobile. a switch base having a wall portion formed with engaging holes corresponding to each other at both left and right ends thereof, and a mounting leg having mounting holes on both left and right walls, with the mounting leg on the right side or the left side having the above-mentioned mounting holes; An electrical component that is engaged with an engagement hole in a wall on the right or left side of the switch base; By having a cover with a mounting protrusion that allows the side mounting leg to be screwed through the mounting hole, the same electrical component can be engaged with both the right and left ends of the switch base. An object of the present invention is to provide a mounting structure for an electrical component that can be easily mounted by means of means and screwing means.

An embodiment of the present invention will be described below with reference to the drawings.

First, in FIGS. 1 to 3, reference numeral 1 denotes a switch base that is elongated from side to side and is fixed to a steering column of an automobile (not shown), and this has elongated holes 2 and 2 for turn levers on both right and left end sides. ' and hazard switch through holes 3, 4 and 3', 4', and are formed substantially symmetrically, and in particular have corresponding engagement holes 5 and 5' at both right and left ends. ' is formed.

Now, the case where the automobile has a right-hand drive will be described with reference to FIGS. 4 and 5. 7 is switch base 1
The light guide is located on the top of the right end of the
Reference numeral 8 denotes a cover attached to the right end side of the switch base 1 so as to cover the light guide 7, and this cover has a mounting protrusion 9 projecting downward.
The mounting protrusion 9 passes through the light guide 7 and projects downward through the hazard switch through hole 4. Reference numeral 10 denotes a hazard switch which is an electrical component, and an operator 11 that protrudes upward is provided at the center of the upper surface, and mounting legs 14 and 15 having mounting holes 12 and 13 are mounted on the upper part of the right and left walls. At the same time, protrusions 16 and 17 are formed to protrude upward on the right and left ends of the upper surface. in this case,
The hazard switch 10 turns on when the operator 11 is pressed and holds the operator 11 in the pressed position, and turns off when the operator 11 is pressed again and returns the operator 11 to its original position above. It is being brought back. In this hazard switch 10, the mounting leg 14 on the right side is connected to the engagement hole 5 of the wall portion 5 on the right side of the switch base 1.
The mounting leg 15 on the left side is inserted into and engaged with the cover 8.
It is fixedly attached to the switch base 1 and the cover 8 by being screwed into the mounting protrusion 9 by a screw 18 through a mounting hole 13. in this case,
The operator 11 of the hazard switch 10 corresponds to the hazard hole 3 of the switch base 1, and the upper end surfaces of the protrusions 16 and 17 are in pressure contact with the lower surface of the switch base 1. Reference numeral 19 denotes a knob, which consists of a shaft part 20 made of acrylic resin having a flange part 20a at the lower end and a knob main part 21 having a shaft cylinder part 21a in the center part, and the top surface of the knob main part 21 has a A light-shielding display panel 22 having a light-transmitting portion 22a that displays a predetermined display mark is attached. This knob 19 is inserted into the hazard switch through hole 3 of the switch base 1 from below, and the shaft cylindrical part 21a of the knob main part 21 is fitted into the upper end part of the shaft part 20 which passes through the light guide 7 and the cover 8. It is assembled by joining and connecting, and in this case,
A compression coil spring 23 is interposed between the flange 20a of the shaft 20 and the lower surface of the light guide 8, and the lower end of the shaft 20 is connected to the hazard switch 1.
It is designed to come into elastic contact with the upper end surface of the operator 11 at 0.

As shown in FIG. 4, a turn lever 24 is rotatably mounted in the turn lever through hole 2 portion on the right end side of the switch base 1.
A turn signal switch (not shown) is operated by rotating the turn lever 24, and the switch base 1 is provided with a cancel mechanism 25 which is interlocked with the turn lever 24.
A cancel cam 26 of the cancel mechanism 25 is supported at the center of the switch base 1, and the cancel cam 26 is connected to a steering wheel (not shown).

Next, the case where the car is a left-hand drive will be described with reference to FIG. In this case, hazard switch 1
The mounting leg 15 on the left side of the switch base 1 is inserted and engaged with the engagement hole 5' of the wall 6' on the left side of the switch base 1, and the mounting leg 14 on the right side is inserted into the cover 8, which is symmetrical to the cover 8. The screw 18 is screwed into the mounting protrusion 9' protruding from the mounting hole 12 through the mounting hole 12. 7' is light guide 7
is a symmetrical light guide. Incidentally, if the automobile is a left-hand drive vehicle, the turn lever 24 and the cancel mechanism 25 are of course also arranged on the left end side of the switch base 1.

In the above configuration, when the knob 19 is pressed down, the operator 11 of the hazard switch 10 is pressed down by the shaft portion 20, and the operator 11 is held at the pressed position. When the hazard switch 10 is turned on, both the left and right direction indicator lamps (not shown) of the car flash, and when the knob 19 is pressed again, the operator 11 of the hazard switch 10 is turned on. When pressed again, the operator 11 is returned to its original position, and the hazard switch 10 is turned off to stop the blinking operation of the left and right direction indicator lamps.

As described above, according to this embodiment, the wall portions 6 are provided at both the right and left ends of the switch base 1, which is substantially bilaterally symmetrical.
and 6', and when the vehicle is a right-hand drive, the mounting leg 1 on the right side of the hazard switch 10 is attached.
4 into the engagement hole 5 of the right side wall 6 of the switch base 1, and the mounting leg 1 on the left side.
5 to the mounting protrusion 9 of the cover 8, and
If the car is a left-hand drive, attach the mounting leg 15 on the left side of the hazard switch 10 to the switch base 1.
Since the mounting leg 14 on the right side is screwed to the mounting protrusion 9' of the cover 8', the same hazard switch 10 can be attached to either the right end or the left end of the switch base 1, and in both cases, one can be attached by engaging means and the other by screwing means, making the attachment work easy, This is suitable for use in automobiles where it is necessary to select between right-hand drive and left-hand drive.

Although the hazard switch 10 is exemplified as the electrical component in the above embodiment, it may be any other switch, and the present invention is applicable not only to switches in automobiles but also to the mounting structure of electrical components of various types of equipment in general.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings, but can of course be implemented with appropriate modifications within the scope of the invention.

As explained above, the present invention engages the mounting leg on the right or left side of the electrical component with the engagement hole in the wall on the right or left side of the substantially symmetrical switch base, and Since the mounting leg on the left or right side of the electrical component is screwed to the mounting protrusion of the cover provided on the right or left end of the switch base, the same electrical component can be attached to the switch base. It is possible to provide a practically extremely convenient mounting structure for electrical components, which can be easily mounted to either the right end or the left end of the electrical component using the engaging means and the screwing means.
