Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a panel-mounted instrument in which an instrument storage case is fixed to a panel. The present invention relates to a case structure for a panel-mounted instrument that does not require support metal fittings.

[Prior Art] FIG. 1 is a perspective view showing a conventional panel-mounted instrument of this type. The meter storage case 1 stores a meter (not shown) therein, and is inserted into the mounting panel 2 through an opening 2a provided in the panel.

At that time, in order to prevent the front surface of the case 1 from sinking into the inside of the panel, protrusions 6a and 6 are provided at the upper and lower ends of the front surface of the instrument storage case 1, which contact the outer surface of the panel.
b is provided.

Furthermore, a fixing bolt 4 is provided on the ceiling of the case 1 by being screwed into a pair of partitions 3, 3 formed at a constant interval.

By pressing the tip of the fixing bolt 4 against the inside of the mounting panel 2, the upper protrusion 6a is pressed against the mounting panel 2, and the instrument storage case 1 is fixed to the mounting panel 2.

Furthermore, the front lower part of the case 1 is a panel opening 2a.
To prevent it from protruding outward from the lower edge of the
A support angle 5 is provided to support the rear lower end of the case 1 at a predetermined height position relative to the panel.

[Problems to be Solved by the Invention] As described above, the conventional panel-mounted instrument requires the support angle 5 as a reinforcing member for fixing the case 1.

Moreover, if the mounting position (vertical position) of this support angle is incorrect, the front lower part of the case 1 may protrude from the opening 2a of the mounting panel, or the lower protruding piece 6 of the case 1 may protrude from the opening 2a of the mounting panel.
b is strongly pressed against the outer surface of the mounting panel 2, resulting in deformation of the lower protrusion 6b or the lower edge of the opening 2a of the mounting panel 2.

[Means for Solving the Problems] This invention has been made focusing on this point, and has the following configuration.

In other words, there are
Provide a protruding piece that contacts the outside surface of the mounting panel.

These protrusions prevent the front of the case from sinking into the panel.

Further, on the lower front part of the case, there is a fitting that allows the lower edge of the panel opening to be fitted to the panel inward side of the protruding piece at the lower end of the front face of the case, and prevents the lower end of the case from moving outward of the panel. form a means;

[Function] The fitting means moves in a direction in which the lower end of the front surface of the case protrudes to the outside of the mounting panel when the instrument storage case attempts to rotate in the front and back directions of the panel using the upper projecting piece as a fulcrum. prevent something.

On the other hand, it is the projecting piece on the upper end of the case front that prevents the lower end of the front of the case from rotating in the direction of recessing into the inside of the panel, and both of these pieces fix the lower part of the case to the panel.

Here, as the fitting means, for example, it is possible to form a cutout step at the front end of the lower surface of the case facing the lower projecting piece of the case, or to fix a convex member or the like.

In addition, in the instrument storage case, a pair of screen portions are further formed at a certain interval on the ceiling of the case, and fixing bolts are screwed into the screen portions in the same manner as in the conventional case.

In this case, the tip of the fixing bolt is pressed against the inside of the mounting panel to press the upper protrusion of the instrument storage case to the mounting panel, thereby firmly fixing the case to the mounting panel.

Even if a rotational moment occurs in the case at this time,
Since the lower front end of the case is prevented from moving relative to the panel by the protruding piece on the front end of the lower surface of the case and the fitting means, the front end of the lower surface of the case remains oriented at a predetermined position on the panel.

[Example] An example of this invention is shown in FIGS. 2 and 3.

Instrument storage case 1 has instruments inside (not shown)
It is stored by inserting into the inside of the mounting panel 2 through the opening 2a provided in the mounting panel 2.

At that time, in order to prevent the front surface of the case 1 from sinking into the inside of the panel, protrusions 6 are provided at the upper and lower ends of the front surface of the instrument storage case 1, which abut against the outer surface of the mounting panel.
a and 6b are provided.

Further, a cutout step 7 is provided at the front end of the lower surface of the case 1 to engage with the inside of the lower edge of the mounting panel opening 2a.

The cutout step portion 7 prevents the case from rotating in a direction in which the lower end of the front surface of the case protrudes outside the mounting panel when the instrument storage case 1 attempts to rotate about the upper projecting piece as a fulcrum. .

Further, on the ceiling of the case 1, there are fixed bolts 4 mounted on a pair of screen sections 3, 3 formed at a certain interval.
It is provided by screwing it in. By pressing the tip of this fixing bolt 4 against the inside of the mounting panel 2,
The upper projecting piece 6a is crimped to the mounting panel 2, and the instrument storage case 1 is firmly fixed to the mounting panel 2.

[Effects of the invention] As described above, according to this invention, a fitting means that fits into the lower edge of the opening of the mounting panel is provided at the front end of the lower surface of the case, so that the case is always attached to the mounting panel in a normal state. This eliminates the need for a conventional support angle that requires high precision in the mounting position, greatly contributing to cost reductions for panel-mounted instruments.

Furthermore, it is possible to prevent deformation of the lower protrusion of the case or the lower edge of the opening of the mounting panel when the fixing bolt is tightened due to the wrong mounting position (vertical position) of the support angle as in the conventional case.
