Description

[Detailed description of the invention] This invention relates to a mounting device, and more specifically, it is a device that allows a switch to be easily mounted on the body of a car, or to be removed as necessary, and to prevent the switch from coming off due to vibrations of the car body. The mounting is related to the switch mounting device obtained.

Conventional switch mounting equipment involves inserting the switch body into a hole drilled in the other end of a mounting bracket with one end fixed to the vehicle body, and then screwing a nut onto a screw cut into a part of the switch body. Measures were taken to install them.

However, this configuration has disadvantages in that it is troublesome to attach and remove the switch from the mounting bracket, and vibrations from the automobile can loosen the nut, causing the switch to rattle or come off.

This invention aims to eliminate the above-mentioned drawbacks, and its features include a cylindrical part that can be inserted into the through hole of the mounting bracket, and a switch body with a thread formed on the outer periphery at one end. A flange portion having a female screw hole into which the cylindrical body can be inserted is integrally formed, and an engaging pawl is provided on the flange side of the cylindrical body portion so that the edge of a notch formed at a position opposite to the through hole engages from one direction. A mounting method in which a protrusion protrudes from the cylindrical side of the flange, and a groove is cut toward the center from the outside of the flange in the protrusion-forming part so that this part can loosen when the protrusion comes into contact with one surface of the mounting bracket. A switch mounting device is provided in which a switch body is mounted on a mounting bracket using a plug.

An embodiment of this invention shown in the drawings will be described in detail below.

Figures 1, 2 and 3 show the switch body in Figure 4,
A mounting plug to be attached to the mounting bracket shown in Figs. 5 and 6. This mounting plug 1 is cast from synthetic resin, as an example, and is formed at one end of the mounting bracket 2, which is a metal plate bent into an abbreviated shape. A cylindrical body part 11 having a diameter slightly smaller than the diameter of the through hole 21, and a female threaded hole 12 integrally formed at one end of the cylindrical body part, into which a switch body to be described later can be screwed is provided in the center. It has a large diameter and a hexagonal flange 13 for easy handling, and a through hole for the mounting bracket 2 shown in FIGS. 4 to 6 is provided on the flange side of the cylindrical body. 2
The edge portions of a pair of notches 22as22b formed at opposite positions of 1 are engaged from one direction with some of the engaging claws 14a, 14b in an abbreviated shape and one surface of the flange 13, and the engaging claws 14a are described later. The protrusions 15 are provided protrudingly in the vicinity of the protrusions 15, and grooves 16 are cut in the center direction from the outside of the flange of the protrusions so that the protrusions can loosen when they come into contact with one surface of the mounting bracket 2. It has become.

The switch mounting device of this invention is composed of a mounting plug and a mounting bracket as described above, and the switch body is attached to a part of the vehicle body (not shown) via this mounting device as shown in Fig. 7. This will be explained using FIGS.

The switch main body 3 has a male threaded portion 31 formed in a part thereof, and the male threaded portion is first inserted into the cylindrical body through the female threaded hole 12 provided on the flange portion 13 side of the mounting plug 1 shown in FIGS. 1 to 3. 11, the cylindrical body side of the mounting plug 2 is inserted into the engaging claw 14a as shown in FIG.
, 14b enters the notches 22a, 22b, and the flange 1
When the mounting plug 1 is inserted into the through hole 21 of the mounting bracket 2 until it comes into contact with the mounting bracket, and then the mounting plug 1 is turned clockwise, the notch 2
2aw 22b, one edge of each of the engaging claws 14a, 1
4b and the flange 13, the protrusion 15 enters the gap a that is approximately equal in width to the plate thickness of the mounting bracket and slightly tapered toward the tip of the locking claw, and the protrusion 15 of the mounting bracket 2. The part 13a of the flange 13, which is more elastic than the other part due to the groove 16 on one side, is loosened outwardly, and as shown in FIGS. 8 and 9, the mounting bracket is It slides on one side and falls into the through hole 23, becoming horizontal, and the engagement claw 14a engages one edge of the notch 22a, and the protrusion 15 comes into contact with and inserts into the through hole, and the mounting plug 1 is removed by vibration or external force. counterclockwise rotation, and can prevent it from falling off from the mounting bracket.

If you want to remove it from the mounting bracket 2, turn it strongly counterclockwise, or use a screwdriver to pry up the part of the flange with the protrusion slightly upward using the groove, and then turn the mounting plug counterclockwise to remove it. It's easy to do.

As described above, this invention includes a mounting bracket having a through hole with notches facing each other in the diametrical direction, a cylindrical part that can be inserted into the through hole of the mounting bracket, and a switch body having a male thread at one end. A flange having a female threaded hole into which a screw can be inserted is integrally formed, and an engaging pawl is provided on the flange side of the cylindrical body part with which the edge of the notch of the through hole engages from one direction. A protrusion that falls into the through hole of the mounting bracket together with a locking pawl is protruded from the cylindrical side of the cylindrical body, and a groove is cut from the outside of the flange of the protrusion forming part toward the center so that the protrusion is in contact with one side of the mounting bracket. Since this part is constructed with a mounting plug that can be loosened, the switch body can be easily attached to the mounting bracket without using tools, making the work easy and preventing accidental falling off due to vehicle vibration. It has the advantage that it is less likely to occur, can be removed if necessary, and can be constructed at low cost with a small number of structural members.
