Description

[Detailed Description of the Invention] The present invention relates to a slide switch with an interlocking lever, and is particularly characterized in that the sliding range of the interlocking lever is limited to be smaller than the stroke of the operating knob.

Conventional slide switches have been thought to include an interlocking lever that is linked to the operating knob, and in this case, it has been considered that the operating knob and the interlocking lever are integrated or connected to form a slide switch with an interlocking lever.

However, in a slide switch in which the operating knob and the interlocking lever are integrated or connected,
The stroke of the operating knob directly corresponds to the sliding range of the interlocking lever, which has the disadvantage that it cannot be used when the sliding range of the interlocking lever is desired to be shorter than the stroke of the operating knob. Another drawback is that the sliding range of the interlocking lever cannot be limited to a certain range with respect to the stroke of the operating knob.

The present invention was developed in view of the disadvantages of adding an interlocking lever to the conventional slide switch mentioned above. Well then,
To provide a slide switch with an interlocking lever in which an interlocking lever is interlocked with an operating knob and the interlocking lever does not operate when the sliding movement of the operating knob exceeds a predetermined sliding range of the interlocking lever.

In order to achieve the above object, the gist of the present invention is to provide an operating knob, a slide switch section that switches contacts in conjunction with the operating knob, and a slide switch section that switches contacts at predetermined intervals along the sliding direction of the operating knob. a moderation piece having both protrusions projecting thereon and interlocked with the operation knob; a cover having a moderation piece groove on the inside in which both the protrusions of the moderation piece engage; and a tip portion protruding to the outside of the cover. an interlocking lever and an interlocking part that has both pressure receiving surfaces that the moderation piece comes into contact with and presses when sliding, and that slides in conjunction with the sliding of the moderation piece,
The moderation half groove has both closed ends and a linear groove parallel to the sliding direction of the operating knob, and a linear groove that extends along an arc centered on both ends of the linear groove and having the predetermined interval as a radius. When the operating knob is slid within a predetermined sliding range of the interlocking lever, the moderating piece is configured to move in conjunction with this sliding so that both protrusions are connected to the linear groove. The moderation piece moves the operating knob to a predetermined sliding range of the interlocking lever by sliding in parallel to the sliding direction of the operating knob to press the pressure receiving surface and sliding the interlocking part. When the projections are slid over the arcuate groove, one of the two projections stops at the closed end of the straight groove, and the other of the two projections only rotates while being guided by the arcuate groove, but does not slide. A slide switch with an interlocking lever characterized in that the interlocking part does not slide.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

It is.

The slide switch with an interlocking lever has an operating knob 1 that can slide along a predetermined path through an operating hole 3a provided in a cover 3, and protrusions 5a, 5a protruding from a predetermined interval. The moderation device has an interlocking moderation piece 5, a cover 3 having a moderation piece groove 3b in which both protrusions 5a, 5a of the moderation piece 5 engage, and an interlocking lever 2 whose tip protrudes outside the cover 3. It is provided with an interlocking part 7 that slides in conjunction with the sliding movement of the piece 5.

As shown in FIG. 3, the operating knob 1 is integrally protruded perpendicularly to an operating base 6 which has a moderation piece movable groove 6a cut out along a direction perpendicular to the sliding direction. It passes through an operating hole 3a formed in the shape of a linear slit in the cover 3 and is slidable along a predetermined path defined by the operating hole 3a. and operating table 6
A slide switch section (not shown), which is made of a flat plate formed into an F-shape, is attached to the bottom surface of the switch. This slide switch portion slides on the switch board 4 and switches unillustrated switching contacts and common contacts provided by pattern printing on the switch board 4.

The moderation piece 5 deviates from the straight line connecting the centers of both protrusions 5a, 5a protruding at a predetermined interval and is spaced apart from the protrusions 5a, 5a by a predetermined distance, as shown in FIG. As shown by the broken line in , it has a protrusion 5b that protrudes downward and parallel to both protrusions 5a, 5a, and both protrusions 5a, 5a can freely slide into a moderation groove 3b, which will be described later, provided on the cover 3. The protrusion 5b is fitted into the moderation piece movable groove 6a of the operating base 6.

The cover 3 has a moderation piece groove 3b on the inside, into which both protrusions 5a, 5a of the moderation piece 5 are guided and engaged.

This moderation groove 3b has closed both ends 3b ₃ , 3b ₃
A straight groove portion _3b1 provided parallel to the operation hole 3a.
and both protrusions 5 centered on both ends of the linear groove _3b1 .
It is composed of both arcuate grooves 3b _{2 ,} 3b ₂ along an arc _whose radius is a predetermined interval between the centers of the grooves 3b 2 and 3b ₂ .
The distance from b ₃ is both protrusions 5a, 5a of moderation piece 5, respectively.
It intersects with the linear groove portion 3b ₁ at a location that matches the predetermined interval of and communicates with the linear groove portion 3b ₁ .

If the stroke range of the operating knob 1 is l, and the predetermined sliding range of the interlocking lever 2 is _l0 , these are set to have a relationship of l> _l0 , and in the case of this embodiment, the linear groove portion _3b1 The distance from the end to the intersection of the arcuate groove 3b ₂ and the straight groove 3b ₁ near the end is approximately equal to l ₀ .

The interlocking part 7 has an interlocking lever 2 whose tip part protrudes outside the cover 3, and both levers 7a, 7a which are provided at both ends to protrude perpendicularly to the interlocking lever 2. The moderation piece 5 is inserted and arranged between both pressure receiving surfaces 7b, 7b facing each other of the moderation piece 7a, and the pressure receiving surface 7b is pressed when the moderation piece 5 slides, and is interlocked with the sliding of the moderation piece 5. and slide.

Then, when the operating knob 1 is slid within a predetermined sliding range _l0 of the interlocking lever 2, both protrusions 5a, 5a are guided by the linear groove _3b1 in conjunction with this sliding, and the moderation piece 5 slides parallel to the sliding direction of the operating knob 1, and causes the interlocking portion 7 and its interlocking lever 2 to slide parallel to the sliding direction of the operating knob 1 and the linear groove portion _3b1 .

Furthermore, when the operating knob 1 is slid beyond the predetermined sliding range _l0 of the interlocking lever 2, both protrusions 5a,
5a stops at the end _3b3 of the straight groove part _3b1 ,

It is an explanatory diagram showing the movement of.

In this case, by sliding the operating knob 1, the moderation piece 5 is also slid, and the interlocking part 7 and its interlocking lever 2 that come into contact with the moderation piece 5 are also slid. At this time, both protrusions 5a, 5a of the moderation piece 5 are fitted into the straight groove part 3b1 of the moderation piece groove 3b of the cover ₃ , and in conjunction with the sliding movement of the operating knob 1, the interlocking part 7 and its interlocking The lever 2 also moves approximately the same distance as the operating knob 1.

FIG. 5 is an explanatory view of the operation when the stroke of the operating knob 1 exceeds the predetermined sliding range _l0 of the interlocking lever 2.

In this case, the moderation piece 5, which moves in conjunction with the operation knob 1, is such that when the stroke of the operation knob 1 becomes _l0 or more, one of the protrusions 5a, 5a moves into the straight groove portion 3b1 of the moderation piece groove 3b of the cover ₃ . It collides with the closed end 3b ₃ and cannot move in a straight line. The moderation piece 5 has one of the protrusions 5a, 5a stopped at the end 3b3 of the straight groove portion _3b1 , and the other of the protrusions _{5a, 5a adjusts the moderation of the cover 3 ,} centering on this end 3b3. It is guided by the arcuate groove portion _3b2 of the single groove 3b and makes an angular movement in an arcuate manner.

That is, the interlocking lever 2 is connected to both protrusions 5 of the moderation piece 5.
When one of a and 5a comes into contact with the end _3b3 of the linear groove _3b1 of the cover 3, it does not slide along the linear groove _3b1 , and the stroke of the operating knob 1 moves within the predetermined sliding range of the interlocking lever 2. It can be made shorter.

As explained above, according to the present invention, the interlocking lever is interlocked with the operating knob when the operating knob is within the predetermined sliding range of the interlocking lever, and when the operating knob is sliding beyond the predetermined sliding range of the interlocking lever. In addition, the interlocking lever can be prevented from operating, and when the operating knob is slid and the interlocking lever that is linked to this sliding movement is used to turn on and off a micro switch, for example, even if the operating knob is given a full stroke,
Since the interlocking lever slides within a predetermined sliding range, it is possible to reliably prevent the microswitch from being damaged due to excessive sliding of the interlocking lever.
