Description

[Detailed Description of the Invention] This @Moe is a new and revised press system for the press ml switch - a darkness in the side street of the city V.

Conventionally, each cypress keyboard has been used as a middle restraining member consisting of an elastomer blade for the press ml switch, etc., for example, as shown in the accompanying drawings.

A half-shaped central mashinkuto (a) that serves as the middle press, and a ring-like nave (12 rings) arranged around it, or a flat kōnaku (12) as shown. In the Frl of the capital C, a free inner part d which is smaller than the opening of the flat part is provided, and a rib shaped like a rib is provided on the outer surface of the flat part. Opas [loaf's profit tl]
, 4j is known, and these relationships) f
The relationship between the control a1, the pressure strike 0, and the loaded load is as shown in each figure (t)l.

When you press this with the pressure control material of 1 fusuma 1 kyo and 2 fusuma, respectively, each stroke sl makes a forging large grape, followed by an ffl lecture snapping movement or a kutsuzuku movement, With the increase of the stroke, the suppressing load decreases rapidly, and the movable finger point 1 touches the fixed finger point (not shown) g2 at the center of the stroke 8. The state becomes y.

And duck! In the case of the pressure control member shown in the figure, the suppressing load suddenly increases by C2 due to the slight elongation of the store after the snap action, and in the case of the SGAIO pressure control member, the suppressing load suddenly increases by C2. The suppressing load increases relatively slowly with respect to the elongation l2, and therefore there is sufficient transparency.
a-g is obtained. In addition, each person (in BL, the upper side of the circle of the double bent knee or when the pressing force is released.
], the lower side is when the pressing force is released.

Therefore, in the above-mentioned conventionally known press control material 1:, does the key operator recognize that he has pressed the switch s, g: jl, with his fingertips? ,But this fingertip feeling is strange...】, 1 again. Despite the recognition that pressure was applied, there are subtle changes in the behavior of one person's fingertips, and this changes as a change in the suppressing load, causing a single chatter drop and bouncing current. There were major disadvantages and drawbacks.

The present invention provides a new and improved AJS material for loincloth button switches that can reliably prevent such chattering and bouncing phenomena. to provide,
This is made of an elastomer with an F-mu structure, and is made of an elastomer with an F-m structure, and is made of an elastomer with an F-m structure. The thin-walled part of the ring is connected, and the ring-shaped thin-walled part of the ring-shaped koji meat capital of the 1: army 2 @?

11 strokes outside the meat capital G: Place the ring-shaped lip of @l on the inner surface of the thin-walled parts of s2 and thread 3, so that its lower end is at the above-mentioned thick inner pace.
Hawk 1ife: It is characterized by having ring-shaped ribs of height s2 that do not reach each other protruding from each other.

Hereinafter, the present invention will be described in detail based on Attachment 1.

First, Fig. 3 shows a central vertical cross-sectional view of the present invention 1: an example of the press control s4f for a push button switch. It is made by integrally molding 1 and 2. Intermediate 1 is central thickness inner -, 2, 3゜4 are respectively part 1. s Tomi, @3 Glue jig-shaped thin wall - 15 is thick wall base I
11.6. ff is a y-shaped rib 17,
A movable contact 8 made of, for example, conductive rubber is integrally supported at the 7th position of the central thickness s1, and this pressure control member can be used as a push button switch S member in various keyboards, for example, on its surface. tJiii fixed camellia point 9 and 1: Required circuit wiring C (not shown) is used as a line on the circuit board 1 with pipes installed. In addition, 11

To explain the operation of the material directly, the push button 181 placed on the ring-shaped knob 6 of the electric power supply unit 1 is pressed to imprint the pressing force of the control member 2, and the thin part 4 of the It bends and deforms to the lower end # of the ring-shaped rib 7 of II2? & is the printed circuit board surface 10&C 114, point A in the ims diagram), and the thin wall 5ait of the line "t'l12"
Next buckling F shape, $415! This happens because the so-called snap action or click action occurs immediately after the BBs are hit twice in a row, and the suppressing load rapidly decreases.

What is important about the pressure control member of the present invention is as follows.

With this snap action, the sg 9y g-shaped 1 block 7 is once exposed from the base 1h10, and then the movable seeding point 8 is moved to II! II
