DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device and a component of an electric device which are inserted into a mounting hole provided on a substrate and mounted on the substrate. Regarding the structure.

2. Description of the Related Art As a conventional structure for mounting components of electronic equipment and electric equipment to a substrate, for example, Japanese Utility Model Publication No. 63-42737.
There is an antenna holding structure described in the issue. In this antenna holding structure, as shown in FIGS. 3 and 4, a spiral portion 14a and an engagement curved portion 14b are provided on the base end side of the antenna 14,
The spiral portion 14a is fitted on a pin 13 protruding from the printed wiring board 11, and the engaging curved portion 14b is formed with an engaging hole 12b formed on the printed wiring board 11 at a predetermined distance from the pin 13.
And the antenna 14 is held on the printed wiring board 11.

However, in the above-described conventional antenna holding structure, the number of parts is large because the pins 13 and the like are required, and the pins 13 and the like are required. In this case, there is a problem that the structure is complicated because the spiral portion 14a and the engaging curved portion 14b must be provided. The present invention solves the above-mentioned conventional problems, and enables electronic equipment and electric equipment parts to be erected on a substrate in a straight state while having a small number of parts and a simple structure, and to contact or mount adjacent parts. It is an object of the present invention to provide an electronic device and a structure for attaching components of an electric device to a substrate, which can reduce the rework after the above operation.

In order to achieve the above object, according to the first aspect of the present invention, a lead terminal portion of a component of an electronic device or an electric device is inserted into a mounting hole provided on a substrate and mounted. In the mounting structure as described above, an appropriate portion below the lead terminal portion of the component is wound in a flat spiral shape, the lower portion of the lead terminal portion is inserted into the mounting hole of the substrate, and the winding portion is formed in the mounting hole. The component is fixed to the upper surface of the edge portion, and the component is erected on the substrate and attached.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic perspective view showing a state immediately before components are mounted on a substrate in a structure for mounting components of an electronic device and an electric device on a substrate according to an embodiment of the present invention, and FIG. FIG. As shown in FIG. 1, the mounting structure of the components of the electronic device and the electric device to the substrate according to the present embodiment includes a lead terminal portion 2 extending downward from both sides of the component 1 of the electronic device and the electric device such as a capacitor. The lower part of 3 is wound in a flat spiral shape. Then, as shown in FIG. 2, the lower ends of the lead terminal portions 2 and 3 of the component 1 are inserted into mounting holes 5 and 6 formed in the substrate 4, and the winding portions 7 of the lead terminal portions 2 and 3 are inserted. ,
The component 8 is engaged with the upper surface 9 of the edge of the mounting holes 5 and 6 so that the component 1 is mounted on the substrate 4 in an upright position. In addition, part 1
The lower ends of the lead terminal portions 2 and 3 may be fixed by soldering H on the back surface side of the substrate 4. As shown in FIG. 2, this component 1 has the winding portions 7 and 8 of the lead terminal portions 2 and 3 fixed to the upper surface 9 of the edge of the substrate 4 in a flat state, and the elasticity of the winding portion. As a result, a straight state is always maintained on the substrate 4 to be set up. Therefore, since the component 1 is hard to fall down, it does not come into contact with an adjacent component (not shown), and rework after mounting can be reduced. Further, since no other parts are required, the number of parts is small and the structure is simple. Further, by providing the flat spiral winding portions 7 and 8 at predetermined height positions in the lead terminal portions 2 and 3 of the component 1, the height of the component 1 from the upper surface of the substrate 4 is set to a predetermined height. Can be positioned in position. In the above embodiment, the electronic device,
Although the capacitor has been described as the component 1 of the electric device, the component 1 is not limited to this, and the lead terminals 2, 3
It can also be applied to other parts having

As described above, according to the first aspect of the present invention, since no other parts are required, the number of parts can be reduced, and an appropriate portion below the lead terminal portion of the part is flattened. The structure is simple because it only needs to be wound spirally. Furthermore, by locking the flat spiral wound portion on the upper surface of the board, the components of the electronic device and the electric device can be erected on the board in a straight state, and contact with adjacent components or rework after mounting. Work can be reduced. Also, by providing a flat spiral wound portion at a predetermined height position in the lead terminal portion of the component, the height of the component from the upper surface of the board can be reduced in a state where the wound portion is locked on the upper surface of the board. It can be positioned at a predetermined height position.
