Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for mounting an electrical device onto a mounting tray (hereinafter simply referred to as a tray).

For example, in the case of in-vehicle electrical equipment, the purpose is to simplify the installation interface with the car body, or to make it easier to attach and remove equipment from the car body.

It is customary to install a tray between the device and the vehicle body.

By the way, first, a conventional method for attaching electrical equipment to a tray will be explained with reference to FIG.

In the figure, (1) indicates bolts (2) attached to two locations on the front of the housing.
) A connecting plate (4) and a handle (5) for fixing the tray (3) to the tray (3), and a block (
This is an electric device having a guide pin hole (7) that is fitted through a guide pin (7) that is attached through a guide pin (7).

However, in the method of attaching an electrical device with two or more configurations, the axial force P of the bolt (2) acts only in the direction of the arrow in the figure. The restraining force in the vertical direction of the electric device (11) includes the mounting plate (4), the seat surface of the bolt (2), and the mounting plate (4).
) and the tray (3).

For this reason, vibrations, especially in the vertical direction, such as in vehicles, etc.

The above-mentioned electrical equipment (
In 1), the tray (3) and the electrical equipment (
There was a problem that No. 11 was easily loosened.

This invention was made to improve the above-mentioned problems, and will be explained below with reference to an embodiment shown in FIGS. 2 and 3.

FIG. 2 is a diagram showing a state in which a heat-staining device is mounted on a mounting tray by the method of mounting an electrical device according to the present invention, and FIG. 3 is a diagram showing cross section AA of FIG. 2.

In the figure, (8) is a first flange which has a dogleg-shaped cross section and has a notch (9) at its tip.

Together with the second flange α@ whose rear section has a dogleg shape.

It is integrally attached to the electrical equipment +11. aυ
is a stopper having a surface still in contact with the inclined surface of the second flange α1, and is attached to the tray (3). +1 is a threaded rod rotatably attached to the tray (3) at a position corresponding to the notch (9) of the first flange (8) on the bin α floor; The above notch (
9), and then by turning the nut (+4), the electric device (1) can be attached to the tray (3).

Since the present invention is as described above, by using the inclined surfaces of the first flange (8) and the second flange a, a component force P1 of the axial force P of the bolt (2) is applied. ．． P2
can be generated in the direction of the arrow.

Therefore, it is possible to hold the electrical equipment in a much more stable manner than in the past, against vibrations and impacts in both the vertical and longitudinal directions.

In the embodiment, two first flanges (8) are used, but they may be integrated. Also.

Although the second flange +I+1 is made into one piece, it may be divided into a plurality of pieces.

Furthermore, as a matter of course, the distribution ratio of component forces P1+P2 is the same as the above-mentioned first
．． Optionally, the angle of inclination of the second flange surface can be changed.

[Brief explanation of drawings]
