Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a method for connecting a plurality of electronic components having a pair of terminals to a wiring board by inserting the terminals into insertion holes of the wiring board. The present invention relates to a wiring board device.

[Technical background of the invention]

For example, when multiple light emitting diodes that display the washing process are installed on a printed wiring board installed on the back side of the operation panel of a washing machine, each of these light emitting diodes must correspond to each window on the operation panel. , these light emitting diodes are held by a holder so that their terminals are arranged horizontally in a row, each terminal is inserted into each insertion hole formed in a horizontal row in a printed wiring board, and each terminal is It is soldered to a printed wiring board.

[Problems with background technology]

However, when inserting each terminal into each insertion hole in the above-mentioned device, the terminals are generally not aligned and the insertion hole has a relatively small diameter, so it is difficult to smoothly insert a large number of terminals into each insertion hole. There is a problem in that the terminal is difficult to insert, making the insertion work troublesome.In addition, in this case, if an attempt is made to forcefully insert the eldest child into the insertion hole, the terminal may be bent, resulting in poor contact. On the other hand, it is conceivable to make the diameter of the insertion hole larger in order to make it easier to insert the terminal, but this increases the gap between the terminal and the periphery of the insertion hole, which tends to make soldering unreliable. [Objective of the Invention] The present invention has been made in view of the above-mentioned circumstances, and its purpose is to connect each terminal of an electronic component to each insertion hole of a wiring board. It is an object of the present invention to provide a wiring board device which can be easily and reliably inserted into a wiring board and which can be reliably soldered.

[Summary of the invention]

The present invention provides a wiring board that connects a plurality of electronic components each having a pair of terminals, with an insertion hole into which one terminal of each electronic component is inserted and an insertion hole into which the other terminal is inserted, which are arranged at approximately right angles. The arrangement is formed into elongated holes extending in the vertical and horizontal directions, so that one terminal of each electronic component can be easily inserted into one insertion hole, and then each other terminal can also be inserted into the other insertion hole. It is characterized in that it can be easily inserted into the insertion hole.

[Embodiments of the invention] An embodiment of the present invention will be described below with reference to the drawings.

First, in FIG. 1, reference numeral 1 denotes a printed wiring board, which is disposed, for example, on the back side of the operation panel of a washing machine.The printed wiring board 1 has various electronic components for controlling and displaying the washing process. It is provided. 2 is a light emitting diode which is an electronic component for displaying the washing process, for example, and this has a pair of long and short terminals 2a and 2 as shown in FIG.
A plurality of terminals, five in this case, are held by the holder 3 so that their respective terminals 2a and 2b are arranged in a horizontal row. And, on the printed wiring board 1,
As shown in FIG. 3, engagement holes 5, 5 are formed on the left side of the holder 3, corresponding to the Ishioka support legs 4, 4, and a light emitting diode 2 is located between these engagement holes 5.5. Five pairs of insertion holes 6 and 7 are formed in a horizontal row corresponding to the pair of terminals 2a and 2b. Here, among the pair of insertion holes 6 and 7, one insertion hole 6 is arranged in the vertical direction (the third
The other insertion hole 7 has a long hole shape extending in the horizontal direction (in the left-right direction in FIG. 3); 6 and the other insertion hole 7 are arranged at right angles. Thus, the holder 3 connects the left Ishioka support legs 4, 4 to the engagement holes 5,
Each light emitting diode 2 is attached to the printed wiring board 1 by inserting and engaging the light emitting diode 2 into one of the insertion holes 6, while the long terminal 2a of each light emitting diode 2 is inserted into one of the insertion holes 6, and the other short terminal 2b is inserted into the insertion hole 6. is inserted into the other insertion hole 7 and connected to a wiring pattern (not shown) of the printed wiring board 1 by soldering.

Next, the procedure for disposing the light emitting diode 2 on the printed wiring board 1 will be described. Five light emitting diodes 2 were held by a holder 3, and the light emitting diodes 2 and the holder 3 were tilted as shown in FIG. In this state, by shifting the holder 3 in the left and right direction, firstly, the long one terminal 21 is 1+--mm1 pos.
- In the case of earthenware 7 live sweets, since the insertion hole 6 on one side has a long hole shape extending in the vertical direction, the terminal 2 on each side
a can be easily inserted into each one of the insertion holes 6. Then, from this state in which each one of the terminals 2a is inserted into each one of the insertion holes 6, the light emitting diode 2 is raised together with the holder 3 as shown in FIG. By shifting, the other short terminal 2b is inserted into the other horizontally long insertion hole 7, and
Left side of holder 3.

The Ishioka support legs 4, 4 are inserted and engaged into the engagement holes 5, 5. In this case, each terminal 2b can be easily inserted into each other insertion hole 7 because the other insertion hole 7 has a long hole shape extending in the horizontal direction.

Therefore, when inserting each one of the terminals 2a into one of the insertion holes 6 in this way, it is done by shifting them left and right, and
When inserting each other terminal 2b into the other insertion hole 7, it can be easily done by shifting it back and forth, so there is no need to forcibly bend the terminal to insert it into the insertion hole. After inserting each pair of terminals 2a and 2b into the respective insertion holes 6 and 7 in this way, solder each terminal 2a.
and 2b are connected to the wiring pattern of the printed wiring board 1, and excess terminals protruding from the back side of the printed wiring board 1 are appropriately cut. In this case, since each of the insertion holes 6 and 7 is elongated, unlike the case where the diameter of the insertion hole is simply increased, soldering can be performed reliably, and soldering is caused by contact due to poor soldering. It will not become defective.

Note that the present invention is not limited to the embodiments described above and shown in the drawings; for example, the light emitting diode 2 may be replaced with a platform for electronic components such as transistors, etc., without departing from the scope of the invention. It can be implemented with appropriate changes.

〔Effect of the invention〕

As is clear from the above description, the present invention includes a plurality of electronic components having a pair of terminals, which are held by a holder so that the terminals form a substantially horizontal row, and the terminals are inserted into the insertion hole of a wiring board. In the wiring board device, the insertion hole portion into which one terminal of each electronic component is inserted and the insertion hole portion into which the other terminal is inserted are arranged at approximately right angles. Since the holes are formed into elongated holes extending in the vertical and horizontal directions, each terminal of the electronic component can be easily and reliably inserted into each insertion hole of the wiring board, and soldering is also possible. It has excellent effects in that it can be carried out reliably and the ease of assembly can be greatly improved overall.
