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.
There is a problem that it is difficult to smoothly insert a large number of terminals into each insertion hole, and the insertion process is troublesome.
In addition, in this case, there is a problem in that if the terminal is forced to be inserted into the insertion hole, the terminal will be bent, resulting in poor contact. On the other hand, it is possible to increase the diameter of the insertion hole 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. A problem arises that causes poor contact.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to easily and reliably insert each terminal of an electronic component into each insertion hole of a mounting board, and also to enable soldering. It is an object of the present invention to provide a wiring board device that can reliably perform the above operations.

[Summary of the invention]

The present invention provides a wiring board that connects a plurality of electronic components having a pair of terminals, in which one insertion hole into which one terminal of the electronic component is inserted is formed in the shape of a long hole extending in the vertical direction, and the other The other insertion hole portion into which the terminal is inserted is formed into a long hole shape extending in the horizontal direction orthogonal to the one insertion hole portion, and the one insertion hole portion and the other insertion hole portion are arranged alternately. The present invention is characterized in that one terminal of each electronic component can be easily inserted into one insertion hole, and then each other terminal can also be easily inserted into the other insertion hole. That is.

[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 on the back side of the operation panel of a washing machine, for example.
is equipped with various electronic components for washing process control and display. 2 is a light emitting diode which is an electronic component for displaying the washing process, for example, and has a pair of long and short terminals 2a and 2b as shown in FIG. Holder 3 so that 2a and 2b are aligned horizontally.
It is maintained by As shown in FIG. 3, the printed wiring board 1 is provided with engagement holes 5, 5 corresponding to both the left and right support legs 4, 4 of the holder 3, and these engagement holes. Five pairs of insertion holes 6 and 7 are formed in a horizontal row between the holes 6 and 5, corresponding to the pair of terminals 2a and 2b of the light emitting diode 2. Here, among the pair of insertion holes 6 and 7, one insertion hole 6 has a long hole shape extending in the vertical direction (vertical direction in FIG. 3), and the other insertion hole 7 It has a long hole shape extending in the horizontal direction (left and right direction in FIG. 3), and the insertion hole portions 6 on one side and the insertion hole portions 7 on the other side are orthogonal and arranged alternately. The holder 3 is attached to the printed wiring board 1 by inserting and engaging the left and right support legs 4, 4 into the engagement holes 5, 5, while each light emitting diode 2 is One long terminal 2a is inserted into one insertion hole 6, and the other short end 2b is inserted into the other insertion hole 7, and a wiring pattern (not shown) is formed on the printed wiring board 1 by soldering. It is connected to the.

Next, the procedure for disposing the light emitting diode 2 on the printed wiring board 1 will be described. Five light emitting diodes 2 are held by a holder 3, and the light emitting diodes 2 and the holder 3 are tilted as shown in FIG. By shifting the holder 3 in the left and right direction, first remove the longer terminal 2.
a into one of the vertically long insertion holes 6. In this case, each one of the terminals 2a can be easily inserted into each one of the insertion holes 6 because one of the insertion holes 6 has a long hole shape extending in the vertical direction. 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 oblong insertion hole 7, and the left and right support legs 4, 4 of the holder 3 are inserted into the engagement holes 5, 5. Match. In this case, since the other insertion hole 7 has a long hole shape extending in the horizontal direction, each terminal 2b
can be easily inserted into the other insertion hole 7. Therefore, when each terminal 2a is inserted into one insertion hole 6 in this way, it is done by shifting it left and right, and when each other terminal 2b is inserted into the other insertion hole 7. This can be easily done by shifting the terminal back and forth, so there is no need to forcibly bend the terminal to insert it into the insertion hole, thereby preventing contact failure. After inserting each pair of terminals 2a and 2b into the respective insertion holes 6 and 7 in this manner, each terminal 2a and 2b is connected to the arrangement pattern of the printed wiring board 1 by soldering, and then the back side of the printed wiring board 1 is Cut off any excess terminals that protrude to the sides. In this case, since each of the insertion holes 6 and 7 is elongated,
Unlike simply increasing the diameter of the insertion hole, soldering can be performed reliably and contact failure due to poor soldering will not occur.

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 an electronic component such as a transistor, 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 each having a pair of terminals, which are held by a holder so that the terminals are substantially aligned horizontally, and the terminals are inserted into an insertion hole of a wiring board. In the wiring board device which is connected to the wiring board by inserting it into the wiring board, one insertion hole into which one of the terminals of the electronic component is inserted is formed into a long hole shape extending in the vertical direction, and the other terminal is formed into a long hole shape extending in the vertical direction. The other insertion hole portion to be inserted is formed in the shape of a long hole extending in the horizontal direction perpendicular to the one insertion hole portion, and the one insertion hole portion and the other insertion hole portion are arranged alternately, With this, each terminal of the electronic component can be easily and reliably inserted into each insertion hole of the wiring board, and soldering can also be performed reliably. Overall, the ease of assembly can be greatly improved. be effective.
