BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to electronic components .

[0002]

2. Description of the Related Art FIGS. 5A and 5B show conventional electronic components and parts.
Is a diagram showing a fine mounting example, in (a), 100 printed circuit board, 101 denotes an electronic component, the printed circuit board 100 has through holes 102 are formed,
This through hole 102 is used for the lead 10 of the electronic component 101.
3 is formed with a certain clearance in consideration of the insertability. This the lead 103 of the electronic component 101
After being inserted into the hole 102, the lead 103 and the printed circuit board 100 are soldered.
1 is attached to the printed circuit board 100.

[0003]

However , in the electronic component having such a conventional structure, the lead 103 is not used.
Since the portion 103a to be inserted into the through hole 102 is formed in a straight line, the electronic component 101 is vibrated during the movement of the assembly line after the lead 103 is inserted into the through hole 102, as shown in FIG. In particular, when the electronic component 101 is relatively heavy, such as a power transistor, the tendency is strong. When the electronic component 101 falls down in this way, the length of the lead 103 protruding from the through hole 102 of the printed circuit board 100 differs, which makes soldering difficult or interferes with the front and rear components. Before mounting, the electronic component 101 is in its original state (standing state)
In this case, there is a problem that the efficiency of the electronic component mounting work is reduced.

[0004]
