Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixture for mounting components to be mounted on electric equipment.

[0002]

2. Description of the Related Art A conventional component attachment will be described with reference to FIG. In order to mount the component 2 such as an enamel resistor on the component mounting plate 1, the L-shaped mounting feet 3 and 4 fixed to both ends of the component 2 are screwed to the component mounting plate, respectively, or as shown in FIG. The other L-shaped foot 4 was screwed to the component mounting plate 1 while one L-shaped foot 3 was inserted into the slit 11 of the component mounting plate 1 and held in a hooked state. That is, the first bent portion 5 and the second bent portion 6
The first bent portion plays the role of fixing the component mounting plate 1 in the horizontal direction, and the second bent portion plays the role in the vertical direction. The use of the hook system instead of screwing in this way aims to contribute to a reduction in man-hours.

[0003]

The screwing of the mounting foot to the component mounting plate as described above has a disadvantage that the screw is loosened, and the mounting man-hour is also required. It is useful for. However, since the bent portion of the mounting foot does not easily penetrate the slit unless the size of the slit is formed to be large with respect to the thickness of the mounting foot, the slit width is formed with a sufficient width. For example, a slit having a width of 3 mm is formed for a plate thickness of 1 mm of the mounting foot. For this reason, there is a drawback in that rattling occurs at a portion where the foot is attached to the component mounting plate, and the component breaks down due to vibration or impact during transportation. It is an object of the present invention to eliminate poor adhesion at a fixed portion between a mounting foot and a component mounting plate.

[0004]

In the component fixing device according to the present invention, in order to eliminate backlash between the component mounting plate and the L-shaped mounting foot, a space having a size corresponding to the thickness of the L-shaped mounting foot is provided. Focusing on inserting and fitting the L-shaped mounting feet, the following configuration was adopted. In a component mounting method in which a first L-shaped mounting foot and a second L-shaped mounting foot fixed to both ends of a component are mounted and fixed on the component mounting plate, a first slit provided in the component mounting plate is provided. The bridge portion sandwiched between the second slits was pushed upward from the lower surface and slightly pushed up from the component mounting plate to form a space on a horizontal plane corresponding to the thickness of the L-shaped mounting foot. That is, the L-shaped mounting foot is inserted into the gap between the lower surface of the bridge portion and the upper surface of the component mounting plate, so that the fitting without rattling becomes possible, and the adhesion between the component mounting plate and the L-shaped mounting foot is improved. The spring property of the bridge contributes to preventing rattling.

In a second aspect of the present invention, a third part is provided to reinforce the horizontal attachment of the component mounting plate by the conventional second bent portion.
A bent portion is added to the mounting foot, a second slit is also added to the component mounting plate, and the tip of the third bent portion of the mounting foot is inserted here, and inserted into two places of the first slit and the second slit. Focusing on the fact that the attached mounting feet work effectively to prevent rattling in the horizontal direction of the component mounting plate, the following configuration was adopted.
In a component mounting method in which a first L-shaped mounting foot and a second L-shaped mounting foot fixed to both ends of a component are mounted and fixed on the component mounting plate, a first slit provided in the component mounting plate is provided. Second
The first L-shaped mounting foot provided with the first bent portion, the second bent portion, and the third bent portion is attached to the first L-shaped mounting leg while the bridge portion sandwiched between the slits is held substantially in the same plane as the component mounting plate. The slit and the second slit were penetrated and knitted, and fitted to the component mounting plate.

In a third aspect of the present invention, in order to reinforce the fixing of the conventional second bent portion in the vertical direction of the mounting plate, a fourth bent portion is added to almost the distal end of the mounting foot, and a spring at this portion is provided. Focusing on the fact that the mounting property is effective in preventing rattling between the mounting plate and the mounting foot, the following configuration was adopted. The first L-shaped mounting foot forms a fourth bent portion at the distal end portion from the third bent portion, so that the spring property of the portion from the fourth bent portion to the tip applies pressure to the upper surface of the mounting plate. Thus, the adhesion between the L-shaped mounting foot and the component mounting plate is improved.

The fourth aspect of the present invention focuses on the fact that it is effective to reinforce the entanglement friction between the conventional L-shaped mounting foot and the slit of the component mounting plate, and has the following configuration. The portion from the vicinity of the first bent portion to the tip of the first L-shaped mounting foot is vertically divided and formed in a comb shape, and the other configuration is the same as that of the second or third aspect of the invention.

FIG. 1 shows an embodiment of the present invention. FIG. 1 (a) is a plan view, and FIG. 1 (b) is a partial cross-sectional front view. The bridge portion 13 sandwiched between the first slit 11 and the second slit 12 formed in the component mounting plate 1 is protruded from its lower surface. The space portion 14 is formed so that the gap between the horizontal surface on the upper surface of the component mounting plate 1 and the lower surface of the bridge portion 13 substantially corresponds to the plate thickness of the first L-shaped mounting foot. For example, when the thickness of the L-shaped mounting foot is 1 mm, the space 1
4 has a height of 1 mm. The first L-shaped mounting foot 3 and the second L-shaped mounting foot 4 fixed to both ends of the component 2 are connected to each other after the one mounting foot 3 is inserted into the space 14, that is, the second mounting foot. When the foot 4 is screwed to the component mounting plate 1, the spring of the bridge portion 13 effectively works to prevent the mounting leg from rattling in the vertical direction of the component mounting plate. It is now possible to achieve both.

FIG. 2 shows a second embodiment of the present invention. The first L-shaped mounting foot 3 has a third bent portion 8 in addition to the second bent portion 6. The component mounting plate 1 has a second slit 12 in addition to the slit 11.
The bridge 13 sandwiched between the two slits is the component mounting plate 1
The first L-shaped mounting foot 3 is fitted in such a manner that it is entangled with the component mounting plate 1 by penetrating the two slits while being held on the same horizontal plane as the surface of the component mounting plate 1. The springiness of the L-shaped mounting foot 3 at the portion in contact with the two slits contributes to preventing rattling in this configuration. Here, the second L-shaped mounting foot 4 is screwed similarly to FIG.

FIG. 3 shows a third embodiment of the present invention.
FIG. 3A shows a front view, and FIG. 3B shows a front view. The first L-shaped mounting foot 3 has a fourth bent portion 9 in addition to the second bent portion 6 and the third bent portion 8. The component mounting plate 1 has a second slit 12 in addition to the slit 11. When the bridge portion 13 sandwiched between the two slits is held in the same horizontal plane as the surface of the component mounting plate 1, the first L-shaped mounting foot 3 passes through the two slits 11 and 12 and Weaving the mounting plate 1
The part from the bent part 9 to the tip part 7 is the component mounting plate 1
Adhere in parallel to In this way, the entanglement of the mounting foot 3 with the component mounting plate 1 is further strengthened, and rattling is prevented against impacts from all directions.

A fourth embodiment of the present invention will be described with reference to FIG. The portion from the vicinity of the first bent portion 5 of the first L-shaped mounting foot 3 to the tip 7 is vertically divided and formed in a comb shape. By thus vertically dividing the mounting foot, the bending workability can be improved and the spring property can be more effectively exerted.

According to the present invention, as described above, the adhesion of the L-shaped mounting foot to the component mounting plate is improved, and the conventional mounting rattling can be prevented. Inhibition factors could be removed. In addition, it has a large industrial value, such as improving the number of installation steps and functions, and at the same time contributing to resource saving and cost reduction by reducing the number of screws and nuts.
