JPS581945Y2 - External connection terminal for reed switch - Google Patents

Description

[Detailed Description of the Invention] This invention relates to an external connection terminal of a reed switch used as a push button switch of a data communication device.

When using a reed switch as a pushbutton switch, etc., attach the reed switch to the external connection terminal,
A method is used in which wiring is connected from the external connection terminal to other circuits.

When attaching the reed switch to the external connection terminal as described above, it is necessary to accurately set the mutual positions of the reed switch and the external connection terminal.

This is because the reed switch is operated by a magnetic field applied from the outside, so it is necessary to set the position so that the external magnetic field can be effectively applied to the reed switch.

For example, in a push button switch in which a magnet is attached to a push button and the reed switch is operated by the magnetic field of the magnet, the magnet needs to approach the center of the contact of the reed switch when the push button is pressed.

Conventional external connection terminals are installed in two parts, 1 and 2 from the front, as shown in Figure 1, and a jig as shown in Figure 2 is used for positioning and installation. .

That is, in FIG. 2, a large number of pins 4 are placed on the board 3.
to fix the external connection terminals 1 and 2, and use the positioning block 5 to position the reed switch 6.
and then the terminal 7 of the reed switch 6.
and 8 and the external connection terminals 1 and 2, respectively, and then the integrated external tangent terminal and reed switch were removed from the board 3.

As mentioned above, when using conventional external connection terminals, a jig is required for installation, and the positioning work is complicated.Furthermore, positioning is performed using pins or blocks, making it difficult to install. There were drawbacks such as the possibility that the glass of the reed switch could be damaged due to the above-mentioned strain.

SUMMARY OF THE INVENTION In order to eliminate the above-mentioned drawbacks, the present invention aims to provide an external connection terminal that can be easily and accurately installed without using a special jig.

The present invention will be explained in detail below based on the drawings.

FIG. 3 is a plan view of an embodiment of the present invention.

In FIG. 3, reference numeral 9 denotes an integral external connection terminal, which is made of a thin metal plate.

On the two opposite sides of the external connection terminal 9, there are markings 10 and 11 indicating the position where the reed switch terminal is attached.
A marking portion 12 for positioning the center of the contact of the reed switch is provided on the other side.

Furthermore, a notch 13 is provided at the end of one of the two sides to facilitate separation from the other side.

In the embodiment shown in FIG. 3, the marks 10, 11 and 12 are made by cutting out a metal plate, but these marks 10, 11 and 12 are made by a method such as a punch mark. Good too.

Next, FIG. 4 is an explanatory diagram of a mounting method using the external connection terminal of FIG. 3.

1. As shown in FIG. 4, mark section 10 of external connection terminal 9
Terminals 7 and 8 of the reed switch 6 are aligned with and 11 for horizontal positioning, and the center of the contact of the reed switch is aligned with the mark 12 for vertical positioning.

Thereafter, the terminals 7 and 8 are soldered to the external connection terminal 9 at the marked portions 10 and 11.

Next, the notch portion 13 is cut, and the external connection terminal 9 is divided into two.

FIG. 5 is a diagram showing the reed switch and the external connection terminal after the above installation work has been completed.

As explained above, if you use the external connection terminal of the present invention,
Positioning is easier, jigs are no longer required for loose mounting, and the work of attaching the reed switch to the external connection terminal can be done as a separate process as a separate unit, improving work efficiency. Extremely effective.
