Abstract

PURPOSE:To eliminate the need for an additional member and enable a height of parts to be regulated when mounted by inserting a lead terminal into the parts hole provided on a printed-circuit board and then performing soldering. CONSTITUTION:LEDs 11a and 11b, where lead terminals 2a and 2b of an LED 1 are cut at cutting positions S1 and S2, are mounted on printed-circuit boards 13a and 13b. Soldering portions 14a and 14b are located on the boards 13a and 13b and there are parts holes for mounting the LEDs 11a and 11b. When a diameter of the parts hole is set to d, the diameter d is smaller than a dimension L1 and is larger than a dimension L2. When the LEDs 11a and 11b are inserted into the parts hole which is provided on the printed-circuit boards 13a and 13b, a protruding portion near the cutting position of the lead terminal hits the printed-circuit boards 13a and 13b and a height of the printed-circuit board 13a and 13b of the LEDs 11a and 11b from the surface can be regulated, thus enabling a height of the LEDs 11a and 11b to be changed.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to lead components, and particularly to the shape of their terminals.

0002

2. Description of the Related Art Conventional lead components, such as LED terminals, have terminal shapes as shown in FIGS. 8 and 9.

FIG. 8(a) is a front view, and FIG. 8(b) is a side view. In the figure, 41 is an LED, 42a and 4
2b are lead terminals of the LEDs 41, respectively. That is, the conventional lead terminals 42a and 42b have the same thickness.

FIG. 9 is a side view showing a case where the LED 41 is mounted on a printed circuit board with its height regulated after mounting. In the same figure, 43 indicates the LED 4
1 is attached to the printed circuit board, 44a and 44b are the soldering parts, and 45 is the LE from the surface of the printed circuit board 43.
This is a height regulating member provided to regulate the height of D41.

[0005]

However, in the above conventional example, since the terminals of the lead components have the same thickness, there are the following problems.

[0006] That is, in order to regulate the height of the component after installation, a separate member is required, and in order to change the height of the component after installation, the height of the separate member provided to regulate the height must be adjusted. Furthermore, in order to avoid cutting the terminals on the back of the printed circuit board after mounting them on the printed circuit board, the lead terminals of the IC are not very long, so a separate member is used to increase the height. The problem was that it could not be changed.

The present invention aims to solve the above problems. That is, an object of the present invention is to provide a lead component that can regulate the height of the component after it is attached without requiring a separate member.

[0008]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a lead component that connects to a printed circuit board by inserting a lead terminal into a component hole provided in the printed circuit board and soldering it. In the above, a plurality of protrusions were provided on the terminal of the lead component.

[0009]

[Function] According to the present invention, since the terminal of the lead component is provided with a plurality of convex portions, in order to regulate the height when the component is attached, the convex portions can be adjusted without using a separate member. This allows the height to be regulated.

The reason why the lead terminals 2a and 2b have different lengths is to indicate the polarity of the LED 1.

As shown in FIG. 1, lead terminals 2a, 2b
is provided with a plurality of convex portions 2c and 2d, and the convex portions make it possible to change the height when the LED 1 is attached to a printed circuit board.

That is, FIG. 2 shows an example in which two types of LEDs whose lead terminals 2a and 2b are cut at cutting points S1 and S2 as shown in FIG. 1 are mounted on a printed circuit board.

In FIG. 2, 11a and 11b are LEDs whose lead terminals 2a and 2b of the LED 1 shown in FIG. 1 are cut at cutting points S1 and S2, respectively.
, 13a and 13b are printed circuit boards mounted with LEDs 11a and 11b, respectively;
4b is a soldering part.

The printed circuit boards 13a and 13b in FIG.
Parts holes for mounting the EDs 11a and 11b are provided, and if the diameter of the parts hole is d, the diameter d is as shown in Figure 1.
It is smaller than the dimension L1 and larger than the dimension L2.

Therefore, when the LEDs 11a and 11b shown in FIG.
a, 13b, and can regulate the height of the LEDs 11a, 11b from the surface of the printed circuit boards 13a, 13b, as shown in FIGS. 2(a) and 2(b).
The heights of D11a and D11b can be changed.

As described above, by providing a plurality of convex portions on the lead terminal of the LED, the same LED can be used.
The effect is that the height after mounting can be changed.

FIG. 3 is a perspective view showing a second embodiment of the present invention. In FIG. 3, 21 is a clip terminal, 22 is a board to which the clip terminal 21 is connected, and 23 is a child board 22.
This is the main board to which the two are connected by clip terminals 21. Further, the clip terminal 21 is provided with a plurality of convex portions.

In this second embodiment, as in the first embodiment, by changing the cutting point of the terminal portion,
The height of the daughter board 22 from the surface of the mother board 23 can be changed.

FIG. 5 is a perspective view showing a third embodiment of the present invention. In the same figure, 31 is an IC, 32 is the IC 31
33 is a printed circuit board on which the IC 31 is mounted, and 34 is another electronic component mounted on the printed circuit board 33.

[0024] In this third embodiment as well, the effect that the height from the surface of the printed circuit board 33 after mounting the IC 31 can be changed is obtained, as in the previous embodiment.

Furthermore, as shown in FIG. 5, by using the IC 31 whose height is regulated by the lead terminal 32,
Another electronic component 34 can be mounted below the IC 31.

FIG. 7 is a side view seen from the direction of the arrow in FIG. That is, as shown in FIG. 7, by mounting electrical components such as another electronic component 34 below the IC 31, three-dimensional mounting becomes possible.

[0027]

[Effects of the Invention] As explained above, according to the present invention,
Since multiple protrusions are provided on the terminal of the lead component,
There is an effect that the height can be regulated by the convex portion provided on the terminal without using a separate member to regulate the height when the component is attached. That is, depending on where the terminal is cut, the height after the parts are attached can be changed using the same part. Moreover, since the bottom of the component can be made higher than the surface of the print, three-dimensional mounting is possible by mounting other components between the component having the terminal and the printed circuit board.
