BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric component mounting apparatus having a structure in which a plurality of terminals of an electric component are inserted into an insertion portion of a wiring board and soldered.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 7, when a connector 1 for a printed wiring board, for example, is attached to a wiring board 2 made of a printed wiring board as an electric component, a plurality of terminals (terminals) 3 of the connector 1 are provided. Are respectively inserted into the insertion portions 4 formed of circular holes formed in the wiring board 2, and thereafter, lands (not shown) serving as connection portions provided around the terminals 3 and the insertion portion 4 are provided. I'm trying to solder and.

[0003]

By the way, in the case of the conventional structure, the width of the insertion portion 4 is set to be substantially the same as the width of the terminal 3 because it is soldered to the terminal 3 to be inserted. It is general and cannot be made too large with respect to the width of the terminal 3. Therefore, it is difficult to insert each terminal 3 into the insertion portion 4, and the terminal 3
If the tip of the terminal is deformed even a little, it becomes more difficult to insert, and it is necessary to strictly control the tip of the terminal 3.

SUMMARY OF THE INVENTION An object of the present invention is to provide a device for mounting an electric component, which makes it easy to insert the terminal into the insertion portion without stricter control of the tip portion of the terminal.

[0005]

In order to achieve the above-mentioned object, the present invention has an electric component having a plurality of terminals, an insertion part into which the terminals are inserted, and a connection around each insertion part. A wiring board having a portion, wherein each terminal and the connecting portion are soldered to each other in a state in which each of the terminals is inserted into the insertion portion, the insertion portion having a width of the terminal. It is characterized in that it has a positioning portion having a width substantially the same as the above and an insertion guide portion communicating with the positioning portion and having a width sufficiently larger than the width of the terminal.

[0006]

[Operation] To attach the electric component to the wiring board, first,
Insert each terminal of the electric component into the insertion guide portion of the insertion portion. At this time, since the insertion guide portion is formed sufficiently larger than the width of the terminal, the terminal can be easily inserted. Then, the electric component is slid to move the terminal from the insertion guide portion to the positioning portion, and soldering is performed in this state. Since the positioning part is set to have almost the same width as the terminal,
Soldering between the terminal and the connecting portion can be surely performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. First, in FIG. 1, a connector 11 as an electric component is for a printed wiring board, and is formed by providing a plurality of L-shaped terminals, in this case, five terminals 13 at one end of a connector housing 12. ing. The tip portion 13a of each terminal 13 is directed downward.
As shown in FIG. 2, L-shaped engaging claws 14 are integrally formed at two locations on the lower surface of the connector housing 12 on one end side.

On the other hand, on the wiring board 15 made of a printed wiring board, five insertion portions 16 each made of a hole are formed corresponding to the terminals 13, and two pairs of engagement portions 16 are engaged. Guide holes 17 and engagement holes 18 are formed at two locations corresponding to the engagement claws 14, and a wiring pattern is provided by printing (not shown).

As shown in FIG. 3, the insertion portion 16 has a positioning portion 16a having substantially the same size as the width of the tip portion 13a of the terminal 13, and the positioning portion 16a communicating with the terminal 1
3 and the insertion guide portion 16b having a width sufficiently larger than the width of the distal end portion 13a. On the lower surface of the wiring board 15, a land (not shown) as a connecting portion is provided around the positioning portion 16a.

The engagement guide hole 17 is formed in the engagement claw 14
The engaging hole 18 is formed into a rectangular shape that can be inserted.
Is formed in a rectangular shape smaller than the engagement guide hole 17 and has a size such that the claw portion 14a at the tip of the engagement claw 14 can be inserted therein.

In the above structure, in order to attach the connector 11 to the wiring board 15, first, the tip end portion 13a of each terminal 13 of the connector 11 is inserted into the insertion guide portion 1 of the insertion portion 16.
6b (see the chain double-dashed line in FIG. 3), and each engagement claw 14 is inserted into the engagement guide hole 17 (see FIG. 4). At this time, since the insertion guide portion 16b is formed to be sufficiently larger than the width of the tip portion 13a of the terminal 13, each terminal 13 can be easily inserted even if the terminal 13 is slightly deformed.

When the connector 11 is slid in the direction of arrow A from the state shown in FIG.
a is moved from the insertion guide portion 16b to the positioning portion 16a (see the solid line in FIG. 3), and the claw portion 14 of each engaging claw 14 is moved.
a comes to engage with the engagement hole 18 (see FIG. 5).

With the connector 11 thus attached to the wiring board 15, soldering is performed in a solder bath (not shown). As a result, the tip end portion 13a of each terminal 13 and the land on the wiring board 15 side are soldered. At this time, the positioning portion 16b is set to have substantially the same size as the width of the tip portion 13a of the terminal 13, so that the soldering between the terminal 13 and the land can be reliably performed.

According to the above-described embodiment, the insertion guide portion 16b of the insertion portion 16 for inserting the terminal 13 is formed sufficiently larger than the width of the tip portion 13a of the terminal 13, so that the terminal 13 is slightly deformed or the like. Even if it does, each terminal 13 can be easily inserted. Therefore, the terminal 13 can be easily inserted into the insertion portion 16 without strict management of the tip portion 13a of the terminal 13.

Further, since the positioning portion 16a of the insertion portion 16 is set to have substantially the same size as the width of the tip portion 13a of the terminal 13, the soldering between the terminal 13 and the land can be surely performed.

Further, in the above-described embodiment, the two engaging claws 14 provided on the connector 11 are engaged with the engaging guide holes 17 and the engaging holes 18 formed on the wiring board 15, whereby the connector 11 Since it is attached and fixed to the wiring board 15, there is an advantage that a separate component such as a screw for fixing the connector 11 is not required and the attaching work can be simplified.

The present invention is not limited to the above-mentioned embodiment, and the insertion portion may be formed as shown in FIG. 6, for example. That is, the insertion section 19 includes the positioning section 19a and the insertion guide section 19a.
It has a substantially V-shape with b and is formed at the end of the wiring board 15, and one end of the insertion guide portion 19b is open. Although not shown, the insertion portions may be formed so that the insertion guide portions of adjacent insertion portions communicate with each other. Further, the electric component is not limited to the connector, but may be applied to an electronic component such as a transistor.

[0018]

As is apparent from the above description, according to the present invention, the insertion portion into which the terminal of the electric component is inserted is a positioning portion having a width substantially the same as the width of the terminal and the positioning portion. Since it is configured to have an insertion guide portion that is communicated with the terminal and has a width that is sufficiently larger than the width of the terminal, it is excellent that the terminal can be easily inserted into the insertion portion without strict management of the tip portion of the terminal. Produce the effect.
