Description

[Detailed description of the invention] The present invention relates to a mounting device for a power selector switch that is fixed to one side wall of a cabinet and whose terminals are electrically connected to a power transformer inside the cabinet, with the aim of improving installation workability. With the goal.

In the following, both the conventional example and the present invention will be explained by taking the installation of the changeover switch as an example. 0 Figures 1 and 2 show the conventional mounting device. ○ Figure 1 shows the power transformer electrically connected to the changeover switch. FIG. 2 shows the configuration in which the power transformer is installed in a cabinet together with a changeover switch.

In other words, conventionally, the changeover switch 1 must be mounted in a sturdy manner because it receives pressure from the outside when switching the power supply voltage. Align the opening 3 of the cabinet 2 so that
The heavy power transformer 6 is also fixed to the inside of the cabinet 2 with screws 7 as shown in FIG. 2, and the electrical connection between the two is established. connects the terminal 8 of the changeover switch 1 to the lead wire 9
It was once connected to the terminal 10 of the power transformer 6.

However, in this case, since the lead wire 9 is used to connect the changeover switch 1 and the terminals 8, 10 of the power transformer 6, the wire preparation work and the winding work of the lead wire 9 around each terminal 8, 10 are required. This has the drawback of poor workability and requiring a lot of man-hours.

Furthermore, since the power transformer 6 and the changeover switch 1 were each fixed individually with screws, the cost increased and the workability was further deteriorated.

Further, since the lead wire 9 is wound around each end -f-8, 10 and then semi-IH-attached, solder tunnels are likely to occur, resulting in poor connection and breakage of the lead wire, resulting in a reduction in quality.

The present invention eliminates the above-mentioned conventional drawbacks; the terminals of the changeover switch are inserted into the printed circuit board from one direction and fixed by soldering, while the terminals of the power transformer are inserted into the printed circuit board in the opposite direction to the insertion direction of the changeover switch. By inserting the switch and fixing it by soldering, the changeover switch and power transformer are electrically connected through the printed circuit board pattern, and the changeover switch is supported by the power transformer through the printed circuit board, improving work efficiency. It was measured.

An example of this will be described below with reference to FIGS. 3 and 4.

FIG. 3 shows the configuration of the power transformer used in this embodiment, and FIG. 4 shows the power transformer installed inside the cabinet together with a changeover switch.

In the figure, 11 is a changeover switch, and its terminal 12 is inserted into the printed circuit board 13 from the component mounting side and fixed by soldering to the copper foil pattern on the back side.

On the other hand, the terminals 15 of the power transformer 14 are also inserted into the printed circuit board 13 from the pattern side and fixed to the pattern by soldering.

Here, a predetermined circuit is formed on the printed circuit board 13 so that the terminals 12 and 15 are electrically connected.

In this state, the four changeover switches 11 are aligned with the openings 17 of the cabinet 16, and the power transformer 14 is fixed to the cabinet 16 with screws 18.

In addition, in FIG. 4, 19 indicates solder.

According to the above configuration, the terminals 12, 15 and the printed circuit board 1
Since the changeover switch 11 is supported by the power transformer 14 through 3, the changeover switch fixing screws that were conventionally required are no longer required, and installation workability is improved.

Note that the changeover switch 11 can be fixed together with other parts by automatic soldering.

In addition, since the terminals 12 and 15 are directly soldered and fixed to the printed circuit board 13, and no lead wires are used, there is no need to wrap the terminals, which further improves work efficiency.
Phenomena such as breakage of lead wires and solder tunnels do not occur.

When the changeover switch 11 is operated, the applied force can be received by the printed circuit board 13 and the power transformer 14, and the mounting strength thereof is large and strong.

As explained above, according to the present invention, the terminals of the changeover switch are inserted into the printed circuit board from one direction and fixed to the pattern surface by soldering, and the terminals of the power transformer are inserted into the printed circuit board in the direction in which the terminals of the changeover switch are inserted. By inserting it from the opposite direction and fixing it by soldering to the pattern surface, the changeover switch and power transformer are electrically connected via the pattern on the printed circuit board, and by supporting the changeover switch with the power transformer, the power transformer and The installation work of the changeover switch is improved, and reliability and quality are also improved, as the changeover switch terminals and power transformer terminals are inserted into the printed circuit board from opposite directions and fixed by soldering. , when the changeover switch is operated, the applied force can be received by the printed circuit board and power transformer.
The mounting condition of the changeover switch will be solid as in FIG. 1.
