Abstract

PURPOSE:To obtain a thin and rugged slide switch by having a projected stripe formed in the sliding direction of the lower end of a slider and a guide groove cut in a fixed body, and designing the projected stripe to slide along inside the guide groove. CONSTITUTION:When an actuator 7 is slid in its transverse direction via a push button 8, the engagement of a positioning projected part 5i with each of positioning recessed parts 2d is changed while the lower part 11a of a mask sheet 11 and a projected stripe 9 slide inside a guide groove 4, so that the sliding of a slider 5 is perfectly made and therefore a moving contact piece 6 slides on each of second switching fixed terminals 3c, 3d to make second switching action. The strength of the slider 5 is thus reinforced by the projected stripe 9 while also improvement in the ruggedness of the slider is made by operation of the mask sheet 11, so that ruggedness and function both required for the slider 5 may be secured even in the case where the thickness of the slider 5 is lessened.

Description

DETAILED DESCRIPTION OF THE INVENTION a. Field of Industrial Application The present invention relates to a slide switch, and in particular, the switch switches between two different modes by pushing and sliding, has an extremely thin overall structure, and This invention relates to a new improvement to ensure sufficient strength of the slider.

b. Prior Art There are various types of slide switches of this type that have been used in the past, but the most representative ones include the configuration disclosed in Japanese Patent Application Laid-open No. 14887/1983. can.

Problem to be solved by the C1 invention: Although not shown in the drawings, as disclosed in FIG. The slider must be slid back and forth to the left and right through this manual operation knob, and it must be strong enough to withstand the operation of the manual operation knob at that time, so the slider must have a sufficient wall thickness. was there.

Therefore, due to the thick wall thickness of the slider, it is difficult to make the slide switch itself thinner and smaller.For example, with the miniaturization of pagers that are often used these days, slide switches are becoming smaller and thinner. It was extremely difficult to meet these demands.

The present invention has been made to solve the above-mentioned problems. In particular, it performs switching between two different modes by pushing and sliding, has an extremely thin overall structure, and has a structure that reduces the strength of the slider. It is an object of the present invention to provide a slide switch which has sufficient functions.

65 Means for Solving the Problems The slide according to the present invention performs a first switching operation by pushing in an operator provided on a slider that is slidably positioned on a fixed body, and slides the operator and the slider. The slide switch is configured to perform a second switching operation by moving the slide switch. It is configured to slide within the guide groove.

81 Effects In the slide switch according to the present invention, since the slider is extremely thin, the slider itself has its own strength due to the protrusion formed at the lower end of the slider.

Therefore, when performing a switching operation by reciprocating the slider from side to side using the operator, the rigidity of the protrusion can prevent the slider itself from deforming against the force caused by the urging force of the operator, and the thin You can get a large and strong slide switch.

f. Example Hereinafter, a preferred example of the slide switch according to the present invention will be described in detail with reference to the drawings.

1 and 2 are for showing a slide switch according to the present invention, and FIG. 1 is an exploded perspective view showing the overall configuration;
FIG. 2 is a sectional view showing the main part of FIG. 1.

What is designated by the reference numeral I in the figure is a box-shaped fixed body with an open top. It consists of a terminal board 3 molded into a.

A guide notch 2b is formed in the front plate 2a of the casing 2, and three positioning recesses 2d are formed in the inner surface of the rear plate 2C.

As shown in FIG. 2, the terminal board 3 includes a pair of first switching fixed terminals 3a, 3b and a plurality of second switching fixed terminals 3c.

The terminal board 3 and the casing 2 are integrally provided with an auxiliary terminal board 3e made of a heat-resistant material such as Bakelite having a
It is constructed by integral molding using a resin mold.

The sliding force direction A on the front plate 2b side of the previous terminal board 3 is as follows:
A guide groove 4 is formed, and this guide groove 4 is connected to this terminal board 3.
The terminal board 3 is not limited to a structure formed integrally with the terminal board 3 and the casing 2, and may be formed by the terminal board 3 and the casing 2.

A slider 5 having a rectangular overall shape is provided on the terminal board 3 so as to be freely slidable along a sliding direction A.
A first movable contact piece 6 provided in a first holding groove 5a provided on the lower surface of the slider 5 is slidably provided on the second switching fixed terminal 3C13d.

A second holding groove 5b provided parallel to the first holding groove 5a.
are formed to slidably engage with the first switching fixed terminals 3a, 3b.

A notch 5d is formed on the front surface 5c of the slider 5 for guiding a protrusion 7a for attaching the button 8 of the operator 7, and a through hole 5e is formed continuously to this notch 5d. .

A locking protrusion 5f for locking the spring member 7b of the operator 7 is formed on the rear wall 5eA of the through hole 5c, and a recess 5g communicating with the through hole 5e is formed at the rear of the upper surface of the slider 5. is provided, and the rear wall 5h of this slider 5
A positioning protrusion 51 that engages with the positioning recess 2d is formed therein. Furthermore, this positioning protrusion 5]
is not limited to a protrusion, but may be a ball.

Further, at the lower part of the front surface 5c of the slider 5, a protrusion 9 is formed in the longitudinal direction along the sliding direction A to be slidably inserted into the guide groove 4. The length is the same as the width of the slider 5 and shorter than the width of the front plate 2a of the fixed body 1, that is, the length in the longitudinal direction.

A second movable contact piece 10 having a U-shaped cross section is connected to an inner surface 7dA of a flange 7d formed between the protrusion 7a and the longitudinal portion 7c of the operating body 7. The movable contact piece 10 is attached by known caulking means (not shown) via a pair of caulking holes 10a.

Therefore, when the operator 7 is mounted on the slider 5, the longitudinal portion 7C is slidably located on the recess 5g,
The flange 7d is located in the through hole 5e and between the locking protrusion 5f and the inner surface 7dA of the flange 7d, so that the flange 7d is held in place by the spring member 7b. The second movable contact piece 10 and the first switching fixed terminals 3a and 3b are kept in a non-contact state, being always urged while being joined to the inner surface 5cA of the front plate 5C.

Further, a mask plate 11 having an approximately C-shape overall shape is bonded to the front surface 5C of the slider 5, and a lower portion 11a of this mask plate If is located within the guide groove 4 and In the guide groove 4, as shown in FIG. 2, a mask plate II and a protrusion 9 are slidably positioned in two layers.

An upper cover member 12 having a C-shape as a whole is provided on the upper part of the fixed body l, and the engagement hole 12 a b' of the upper cover member I2 engages with the locking portion 2g of the caning 2. .

Therefore, when assembling the slide switch according to the present invention, the slider 5 on which the second movable contact piece 10, the mask plate 11, and the operating body 7 are attached is mounted on the fixed body I consisting of the casing 2, the terminal board 3, and the terminal board 3. , Finally, the upper part part 1
By attaching 2 to 1, all assembly can be easily completed, and for example, not only manual assembly but also automatic assembly can be performed extremely easily.

The slide switch G according to the present invention is constructed as described above, and two operations thereof will be explained below.

First, when the push button 8 is pushed in, the operator 7 is pushed inward against the spring force of the spring member 7b, and the second movable contact 10 and the first switching fixed terminals 3a, 3b are electrically connected. Therefore, the first switching operation is obtained.

Further, when the push button 8 is released, the operator 7 returns to its original state due to the spring force of the spring member 7b, and the conduction between the first switching fixed terminals 3a and 3b is released.

Next, when the operator 7 is slid laterally via the push button 8, the engagement between the positioning protrusion 51 and the positioning recess 2d changes, and the lower part 11a of the mask plate 11 and the protrusion 9 are guided. Since the slide 5 slides in the groove 4, the slide 5 is completely slid, and the movable contact piece 6 touches each second switching fixed terminal 3.
C, by sliding on 3d and by the well-known switching operation,
A second switching operation is performed.

During the aforementioned pushing and sliding operations of the operator 7, this slider 5 has the through hole 5e, so its wall thickness is extremely thin and its rigidity is weaker than that of conventional sliders. The strength of the slider 5 is reinforced by the protrusion 9, and the rigidity is further improved by the action of the mask plate 11, so that the thickness of the slider 5 can be reduced by about 40% compared to the conventional structure, for example. In this case, the rigidity and function of the slider 5 are ensured.

Although the above-described guide groove 4 is formed on the terminal board 3, which is the fixed body 1, the guide groove 4 is not limited to this configuration, and may be formed on the front plate 2a of the casing 2, for example. This goes without saying.

g1 Effects of the invention Since the slide switch according to the invention is constructed as described above, even when the thickness of the slider is made extremely thin, sufficient rigidity can be obtained due to the action of the protrusions.
The shape of this type of bush slide type slide switch can be significantly reduced in size.

Further, all the components can be assembled from above, making assembly easy and automatic assembly possible.
