Description

[Detailed Description of the Invention] The present invention relates to a mounting device for mounting a housing of a control device, a counter, a meter, etc. to a panel.

For example, when installing a control device housing that houses electronic elements, etc. to a panel, a hole (hereinafter referred to as a panel cut) that matches the dimensions of the housing is usually made in the panel.
At the same time, a flange is provided on the front of the casing, the casing is inserted into the panel cut from the front of the panel, the flange is brought into contact with the front of the panel, and the casing is fixed to the panel using a mounting device from the back of the panel. are doing.

Many such mounting devices for the housing have been proposed and put into practice, for example,
No. 6829, Utility Model No. 126053 or Special Publication No. 1987-
As shown in Publication No. 41558, grooves are provided on the top and bottom surfaces of a housing made of molded synthetic resin, and mounting brackets are attached to these grooves and installed at the rear bent portion of the mounting bracket and the rear of the housing. The screws are screwed into the screw holes, or the rear bent portion of the mounting bracket is fitted into the screws provided at the rear of the casing.

However, in a mounting device with such a structure, grooves are provided on the top and bottom surfaces of the housing, so
A protrusion corresponding to the depth and length of this groove is formed within the housing. As a result, the interior of the housing becomes narrow, the size and shape of elements to be housed are restricted, and the mold for molding the housing becomes complicated and expensive.

The present invention was made to solve the problems of the conventional methods as described above, and it is possible to mount a housing that has a spacious interior and can be mounted on a panel extremely easily without providing any grooves or the like in the housing. The purpose is to obtain a device.

In order to achieve the above-mentioned purpose, the housing mounting device according to the present invention inserts the housing into the panel cut from the front of the panel and fixes the housing from the rear of the panel, and has a flange on the front. A housing including a mounting part having screw holes in at least two places on the rear surface, a projecting piece that projects rearward from the inside of the mounting part and forming a horizontal groove on the outside, and a long piece and a bent part. and a short piece with a through hole provided in the bent portion, and after the housing is inserted into the panel cut, the short piece of the mounting bracket is attached to the protrusion of the protruding piece provided on the housing. At the same time, align the long piece along the side of the housing, and screw a screw into the threaded hole of the housing through the through hole provided in the bent part of the mounting bracket, and connect the flange of the housing and the mounting bracket. It is characterized by clamping and fixing the panel with the tip of the panel. The present invention will be explained below using the drawings.

FIG. 1 is a perspective view of an embodiment of the present invention, and FIG. 2 is a sectional view showing how it is attached to a panel. In the figure, reference numeral 1 denotes a synthetic resin housing housing electronic elements, internal components, etc., and a flange 2 is provided on the front surface. The flanges 2 do not necessarily need to be provided around the front surface of the housing 1, and may be provided only on the left and right sides, for example. 3, 3a are mounting parts bent inward from the rear end of the housing 1; 4, 4a are projecting pieces projecting rearward from the inside of the mounting parts 3, 3a; both projecting pieces 4, 4a;
Concave stripes 5 and 5a are formed on the outside of each of the grooves. 6 and 6a are screw holes provided in the mounting parts 3 and 3a.

Reference numeral 11 denotes a mounting fitting, which is composed of a long piece 12, a bent portion 13, a short piece 14 formed substantially parallel to the long piece 12, and a through hole 15 provided in the bent portion 13.

Next, the operation of attaching the casing to the panel using the present invention configured as described above will be explained. First, as shown in FIG. 2, the casing 1 is inserted into the panel cut Pc from the front side of the panel P, and the flange 2 is brought into contact with the panel P. Next, on the rear surface of the panel P, the long pieces 12 of the mounting bracket 11 are brought into contact with both side surfaces of the housing 1, and the short pieces 14 are fitted into the grooves 5, 5a of the projecting pieces 4, 4a.

In this way, the side surfaces of the short pieces 12 of the mounting bracket 11 fit into the grooves 5, 5a of the projecting pieces 4, 4a, and the long pieces 12 extend along the side surfaces of the housing 1, with the tip end facing the panel P. Since the mounting bracket 11 is positioned in contact with the back surface of the housing 1, there is no fear that the mounting bracket 11 will open outward or cause looseness, and the through hole 15 of the mounting bracket 11 is correctly aligned with the screw hole 6 of the housing 1.

In this state, when the screws 20 are screwed into the screw holes 6 and 6a from the through hole 15, the mounting bracket 11 moves forward as the screws 20 are screwed in, and the flange 2 of the housing 1 and the tip of the mounting bracket 11 move forward. The casing 1 is securely fixed to the panel P by sandwiching the panel P between them.

In the above explanation, the case is shown in which the screw holes 6, 6a are provided directly in the mounting parts 3, 3a of the housing 1, but nuts may also be embedded. Although a case is shown in which the mounting portions 3 and 3a and the projecting pieces 4 and 4a are molded separately, they may be separately molded and bonded to the housing 1 with an adhesive. Incidentally, as shown by broken lines in FIG. 1, assembly is facilitated by molding the housing 1 by dividing it into two symmetrical parts.

FIG. 3 shows another embodiment of the mounting bracket 11, in which a shows an example in which the tip of the long piece 12 is formed into a square shape to increase strength, and b shows an abutment part 16 at the tip of the long piece 12.
This is intended to increase the contact area with the panel P.

As is clear from the above explanation, according to the present invention, there is no need to provide a groove etc. in the casing, so there is no protrusion into the casing, the interior can be used effectively, and the mounting and positioning of the mounting bracket is easy. Therefore, installation time can be shortened. Furthermore, since the outer shape and inner diameter of the casing are simple, the mold can be manufactured easily and inexpensively, and its lifespan can be extended.
