Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for assembling electronic components, and particularly to a method for assembling electronic components using a multi-piece assembly method.

This multi-piece manufacturing method has the advantage of being excellent in mass production. 1 to 6 are diagrams for explaining a conventional assembly method of this type.

As shown in FIG. 1, a large number of printed circuit boards 2 (four in this embodiment) of a predetermined shape are punched out from a relatively wide flat board body 1, and the board is returned to a flat board shape. 3 in the figure is a cut line when the printed circuit board 2 is punched out.

Next, as shown in FIG. 2, the terminal portions 5 of electronic components 4 such as resistors and capacitors are inserted into each printed circuit board 1, and each terminal portion 5 is soldered 6 (see FIG. 3).
. Then, each printed circuit board 2 is individually separated from the circuit board body 1 (see FIG. 4), and the printed circuit board 2 is inverted as shown in FIG. 5 and inserted into the case 7. Reference numeral 8 denotes a board holder cut out from the inner surface of the case 7, by which the printed circuit board 2 is positioned. Thereafter, as shown in FIG. 6, the outer periphery of the printed circuit board 2 and the inner periphery of the case 7 are soldered 9 to fix the printed circuit board 2, thereby completing the assembly of the components.

Although this multi-piece manufacturing method is excellent in mass production, the conventional method requires a large number of man-hours and has problems in terms of work efficiency.

The purpose of the present invention is to eliminate such drawbacks of the prior art,
To provide a method for assembling electronic components with good workability and low production cost.

Next, an embodiment of the present invention will be described using FIGS. 7 to 12. FIG. 7 is a plan view of a flat board body 11, which is composed of one frame 12 and a plurality of (four in this embodiment) printed circuit boards 13. A narrow connecting portion 14 is left between the portion 12 and the printed circuit board 13 and between the printed circuit boards 13,
A penetrating portion 15 for separation is formed. Although not shown, the printed circuit board 13 is provided with a through hole for inserting an electronic component 16 (described later) and a conductive pattern for forming an electronic circuit.

Incidentally, a separation line 17 such as a perforation or a V-groove is provided in the intermediate portion of the connecting portion 14 in order to facilitate separation of the frame portion 12 from the printed circuit board 13 and the separation of the printed circuit boards 13 from each other.

As shown in FIG. 9, terminal portions 18 of electronic components 16 such as resistors and capacitors are inserted into each printed circuit board 130, and then each printed circuit board 13 is inserted into the case 1.
9 is covered (see Figure 10).

The distance between the side walls facing the case 19 is the same as that of the printed circuit board 13.
This substantially coincides with the distance between the opposing side lines of the case 190, thereby regulating the position of the case 190 in the front and back as well as in the left and right directions with respect to the printed circuit board 13.

Further, as shown in FIG. 8, a notch 20 is formed in the side wall at a position facing the connecting portion 14 of the substrate element 11, and the upper end surface 21 of the notch 20 comes into contact with the upper surface of the connecting portion 14. , the insertion dimension of the case 19 into the printed circuit board 13 is regulated.

After inserting the case 19, as shown in FIG. Then, the printed circuit board 13 with the case is individually separated from the circuit board body 11 (12th
(See figure) Complete assembly of electronic components.

The present invention has the configuration as described above, and this assembly method requires fewer soldering steps than the conventional method, has good workability, and is a method of assembling electronic components with low production costs. can be provided.
