Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a switch with an indicator, which is used by being attached to an operation panel, for example, and which has both a switch function and a display function.

[Conventional technology]

Conventional examples of this type of switch with an indicator are shown in FIGS. 13 and 14.

The switch 2 with an indicator shown in Fig. 13 has a fixed printed circuit board (
In this specification, this refers to a hard printed circuit board as opposed to a flexible printed circuit board, and the front side of ) 10 (upper side in the figure)
A display 12 such as an LED display is attached to the rear side, and a switch 16 is attached to the rear side with a space for an operating mechanism, both of which are placed inside a case 8 consisting of a holder 4 and a cover 6 made of an insulating material. A part of the printed circuit board 10 is stored at the rear for external connection.

In addition, a translucent operation cover 20 is provided inside the front part of the case 8.
is fitted, and by pushing or releasing it, the switch 1 is activated by the operation mechanism consisting of two movable pieces 22, 24 and a reversing spring 26 connecting them.
The switch 16 can be operated by pushing and releasing the actuator 18 of No. 6. Switch 16 at that time
An electrical signal from the outside to the outside and an electrical signal from the outside to the display 12 corresponding to the operation of the switch 16 are transmitted via the printed circuit board 10 provided to the outside.

The switch 28 with an indicator shown in FIG. Bend the terminals 14 and 1 of the display 12 and switch 16 in two steps, front and back.
7 is soldered and a part is pulled out to the rear.

Further, as a part of the operation mechanism of the switch 16,
The movable piece 3 is mounted in front of it by two left and right coil springs 34.
2 is supported, and the actuator 18 of the switch 16 is operated by pushing and releasing it with the operation cover 20.

[Problem to be solved by the invention]

However, in any of the above switches 2 and 28 with an indicator, there is a space for the terminal 14 and the operating mechanism between the indicator 12 and the switch 16, and there is also space for the terminal 14 behind the switch 16.
Due to reasons such as the need for 7 spaces, the depth,
, Lt are all large, which is a fundamental problem.

In addition, in the switch 2 with an indicator shown in FIG. 13, in order to reduce costs by using only one fixed printed circuit board 10, the terminals 14 of the indicator 12 are arranged in one row as shown in the figure. If the number of terminals 14 is large (for example, 12 with a 4-digit numerical display)
), the pitch of the terminals 14 inevitably becomes smaller, and when soldering, it is sometimes necessary to pay close attention to avoid shorting between terminals due to solder, resulting in poor assembly workability. There is.

On the other hand, in the switch 28 with an indicator shown in FIG. 14, a flexible printed circuit board 30 is used and is bent horizontally, so that the terminals 14 of the indicator 12 can be arranged in two rows, making it possible to perform the above-mentioned work. Although there is no problem of deterioration in performance, since the flexible printed circuit board 30 is used, there is a problem that the cost is higher than in the case of the fixed printed circuit board 10.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a switch with a display that can be reduced in depth and that can utilize a plurality of rows of terminal arrays on a single display even when a fixed printed circuit board is used.

[Means to solve the problem]

In order to achieve the above object, a switch with an indicator of the present invention includes a case made of an insulating material, a printed circuit board arranged approximately parallel to the front surface of the case inside the case, and a part of which is exposed outside the case; A display attached to the front side of the printed circuit board inside, a switch attached to the rear side of the printed circuit board, and a translucent operation cover fitted into the front part of the case so that it can be moved in the pressing direction. The device is characterized by comprising an operation mechanism that operates the switch by reversing the pressing force in response to the pressing operation of the operation cover.

In that case, the operation cover may be made linearly movable in the front-rear direction or may be rotatable in the back-and-forth direction.

In addition, a bent lever-like movable piece is stored in the bottom of the case, its fulcrum is removed from the case, and by pushing one end of this movable piece with a foot extending from the cover, the other end can be used to move the switch to the rear of the switch. The operating mechanism may be constructed by pushing an actuator that is protruded to the side.

Alternatively, the case may be constructed of a holder and a cover, and a reinforcing leaf spring constituting the operating mechanism may be fitted into the bottom of the holder, and the movable piece may be fitted from above.

In addition, the printed circuit board may be a fixed printed circuit board or a flexible printed circuit board (if a part of it is to be taken out from the side of the case, the rear corner of the case shall be removed, and the printed circuit board may be used as a flexible printed circuit board). If a portion is to be exposed from the rear of the case, it is optional whether or not to remove the rear corner of the case.

[Effect]

In the above-mentioned switch with display, the printed circuit board is placed inside the case almost parallel to the front of the case, and the display and switch are attached to the front and rear surfaces, so the space in the front and rear directions inside the case is effectively used. Therefore, the depth can be reduced compared to conventional switches with indicators.

Moreover, for the same reasons as above, even when using a fixed printed circuit board, the terminal arrangement of the display device should be arranged in a single row with 9
There is no need to bend the board 0 degrees, and multiple rows of terminal arrays can be used on a single printed circuit board.

〔Example〕

FIG. 1 is a longitudinal sectional view showing a switch with an indicator according to an embodiment of the present invention. FIG. 2 is a cross-sectional view taken generally along line II of FIG. FIG. 3 is a view showing the inside of the bottom of the case of the switch with indicator shown in FIG. 1.

The switch 4o with an indicator of this embodiment includes a box-shaped holder 44 with an open front side (left side in FIG. 1) and a rectangular cylindrical cover 46 that fits over the box-shaped holder 44 from the opening side. The case 48 is made of an insulating material.
A fixed printed circuit board 50 is disposed therein almost parallel to the front surface of the case 48, and a portion of the fixed printed circuit board 50 is protruded from one side of the case 48 (to the side) for external connection.

A display 52 such as an LED display is attached to the front side (left side in FIG. 1) of the printed circuit board 5o inside the case 48, and a display 52 is attached to the rear side of the printed circuit board 50.
A switch 56, such as a tactile switch, is attached back to back with 2, and its actuator 562 is protruded to the rear side.

521 and 561 in the figure are terminals of the display 52 and switch 56, respectively, and are soldered, for example, to both sides of the printed circuit board 50.

The reason why the display 52 and the operation cover 60 (described later) are tilted upward in FIG. 1 is because the upper side in the figure is the upper side when the switch 4o with the display is normally used.
This is to make the display on the display 52 easier to see from diagonally above, but it does not necessarily have to be tilted that way (for example, see the example in FIG. 5).

In this embodiment, a translucent operation cover 60 is fitted into the front surface of the case 48 so as to be movable (slidable) in the front and rear directions as indicated by arrow A. This operation cover 60 may be transparent or translucent, or may be colored.

Furthermore, in this example, two support parts 441 are juxtaposed and protruded from the bottom surface of the holder 44, and on top of the two support parts 441, elastic levers each bent in an inverted C-shape when viewed from the side (see FIG. 2) are mounted. Each movable piece 648% 64b is placed on the support part 441 as a fulcrum, and each movable piece 64a,
Using the long side end 641 of 64b as a point of emphasis, push and release the two legs 601 extending from the operation cover 60 in the direction of arrow B, and move each movable piece 64a, 64b accordingly. The actuator 562 of the switch 56 is pushed and released as shown by the arrow C using the short side end 642 as the point of action, thereby configuring the operation mechanism of the switch 56. That is, in this operating mechanism, the operating cover 60 is moved by the movable pieces 64a and 64b.
In response to the pressing operation, the actuator 562 of the switch 56 is operated by reversing the pressing force in a direction opposite to the pressing direction.

When the operating mechanism of the switch 56 is configured in this manner, the structure is simpler than that of the conventional operating mechanism, and thus the number of parts is reduced and the depth, which will be described later, is also reduced.

The reason why the two movable pieces 64a and 64b are provided is to enable the actuator 562 of the switch 56 to be operated more reliably even if the operation cover 60 is tilted and pushed. It's good as well.

Furthermore, if a reinforcing leaf spring 66 is provided on the front side of the movable pieces 64a and 64b as in this example, the movable pieces 64a and 64b can be
, 661 in Figure 0 is preferable because it can increase the return force of 64b and the operation cover 60, but is not essential.
are locking pieces extending from both sides of the reinforcing leaf spring 66 to prevent displacement.

In the above switch 40 with an indicator, a printed circuit board 50 is arranged inside the case 48 almost parallel to the front surface of the case 48, with a part of it exposed outside the case 48, and an indicator is mounted on the front and rear surfaces of the printed circuit board 50. 52 and the switch 56 are installed back to back, so for example, the terminal 52 of both
The lengths of 1 and 561 do not affect the depth dimension, so the space in the front and back direction inside the case 48 is effectively used (effectively). , can be significantly reduced.For example, in the conventional switch 2.28 with an indicator, the depths L+, L
x was about 36 mm in each case, but in the switch 40 with an indicator of this embodiment, the depth is about 19 mm.
We were able to reduce it to about half of what it used to be. Therefore, by using the switch 40 with an indicator, it is possible to save space and downsize the device.

Moreover, since the printed circuit board 50 is arranged almost parallel to the front surface of the case 48, the conventional switch with display 2
Unlike the case of 9, the terminals 521 of the display 52 are arranged in one row.
There is no need to bend it 0 degrees, and one fixed printed circuit board 50 can be used to arrange two rows (or more) of the terminals 521 of the display 52, so even if there are a large number of terminals 521, soldering is easy. The work is easy, and therefore the workability of assembly is improved. Moreover, since only one printed circuit board is required, the cost can be reduced.

However, if a part of the printed circuit board 50 is taken out from the side of the case 48 as described above, even if the switch 40 with display device is inserted into an operation panel etc. and an attempt is made to attach it, the printed circuit board 50 that has come out It gets in the way and makes installation difficult.

Therefore, in order to prevent this, this switch 40 with an indicator
As shown in FIG. 1, the printed circuit board 50 of the case 48 (more specifically, the holder 44 in this example)
Remove (cut) the rear corner of the side opposite to where you took it out.
It's on. 481 in the figure is the cut surface.

To describe the method of cutting more specifically, a circular arc 72 whose center is a point P on the front side where the printed circuit board 50 exits the case 48 and whose radius is the distance of the case 48 from that point P to a point Q on the opposite side. At least the cut surface 481 is made to fit inside. The cut surface 481 may be a flat surface as in the illustrated example, or may be a rounded surface (curved surface).

To attach such a switch 40 with an indicator to an operation panel, first, as shown in FIG. Insert the part of the printed circuit board 50 that came out. This opening 781 corresponds to the outer shape of the switch 40 with an indicator.

In that case, a connector 76 for external connection may be attached to the printed circuit board 50, or a connector 76 for external connection may be attached to the printed circuit board 50.
could be longer. In addition, 74 in the figure is the case 48
The panels attached to the left and right sides of the outside are U-shaped temporary springs.

Next, as shown in FIG. 3B, the switch 40 with an indicator is rotated around the aforementioned point P. At this time, since the rear corner of the case 48 is cut as described above, the case 48 does not come into contact with the operation panel 78.

Then, when the switch 40 with an indicator is further rotated and pushed into the operation panel 78, the switch 40 with an indicator is completely fitted into the opening 781 of the operation panel 7, as shown in FIG. It is fixed by a spring 74.

Next, an example of the assembly procedure of the switch 40 with an indicator will be explained with reference to FIGS. 1 to 3. First, the reinforcing leaf spring 66 is fitted into the bottom of the holder 44 from above, and then The movable pieces 64a164b are respectively fitted. In that case, in this example, each movable piece 64a, 6. llb is provided with a side piece 644 and a locking piece 643, and a lifting prevention part 444 is provided in the holder 44 and engages with these, respectively.
and a protrusion 443 (see Fig. 3, etc.),
The movable pieces 64a, 64b can be fitted onto the support part 441 in a sliding manner, and they also prevent the movable pieces 64a, 64b from floating up suddenly after fitting, which makes the assembly work extremely easy. becomes easier.

Next, a printed circuit board 50 having a display 52 and a switch 56 attached to the front and rear surfaces is fitted onto the printed circuit board 50 with a portion thereof exposed. The cover 46 is then placed on them from the front, and the operation cover 60 is then fitted from the front, thereby completing the assembly.

In other words, in the above-mentioned switch with display 40, since the parts can be inserted in order from the bottom, it is very easy to assemble not only the operating mechanism but also the entire assembly, and it is easy to adapt to automation of assembly.

Incidentally, if the fixed printed circuit board 50 is used as the printed circuit board as in the above embodiment, the cost can be reduced compared to the case where a flexible printed circuit board is used. Good (
In this way, the flexible printed circuit board can be made longer and can also be used as wiring, eliminating the need for relay cables between the switch with display and other devices (for example, the motherboard). , making it easier to connect with other devices.

FIG. 5 shows an example in which a flexible printed circuit board 80 is used. In this case, if a reinforcing plate 82 is also used inside the case 48 as in this example, the other structure can be changed from the case of the above-mentioned switch with indicator 40. It can be completely shared, and can be easily adapted to either fixed or flexible printed circuit boards, depending on the user's needs.

Furthermore, when using the flexible printed circuit board 80,
For example, as shown in FIG. 6, it is folded along the wall inside the case 48 and a part of it is attached to the holder 44 and the cover 4.
6 and out from the rear surface of the case 4. In this case, the rear corner 482 of the case 4 does not necessarily need to be cut as in the embodiment shown in FIG. It becomes possible to insert it into an operation panel, etc. Of course, for reasons such as sharing the case 48 with the embodiment shown in FIG. 1 or unifying the design, the rear corner portion 482 may be cut as described above.

In addition, as in this example, the reinforcing plate 82 is removed within 4 days of the case.
By wrapping both the front and back sides of the flexible printed circuit board 80, the terminals 52 of the display 52 and the switch 56 can be connected on both the front and rear sides while using the printed circuit board 80 with a single-sided conductor.
Since 1 and 561 can be soldered, costs can be reduced compared to the case where a double-sided conductor printed circuit board is used.

FIG. 7 is a sectional view showing a switch with an indicator according to another embodiment of the invention. FIG. 8 is a cross-sectional view taken roughly along the line ■--■ in FIG. 7, but the terminal 521 on the left half of the display 52 is not shown. FIG. 9 is a diagram showing the inside of the bottom of the case of the switch with indicator shown in FIG. 7.

In order to avoid redundant explanation, parts that are the same or correspond to those of the embodiment described in FIGS. 1 to 6 above are given the same reference numerals, and the following description will mainly focus on the differences from the above embodiment.

The basic configuration of the switch with indicator 140 of this embodiment is almost the same as the switch with indicator 40 of the previous embodiment, except for the operating mode of the operation cover 60.

That is, the fixed printed circuit board 50 is placed inside the case 48 that includes the holder 44 and the cover 46.
It is arranged almost parallel to the front surface (left side in FIG. 7) of the case 48, and a part thereof is protruded from one side of the case 48 (to the side) to be used for external connection.

A display 52 is attached to the front side of a printed circuit board 50 inside the case 48, and two switches 56 (in this example, see FIG. 8) are attached to the rear side of the printed circuit board 50, and the actuator 562 is moved backward. It's out on the side. The reason why it is preferable to tilt the display 52 and the operation cover 60 is as described above.

In the front part of the case 48, unlike the previous embodiment, in this embodiment, there are two fittings that rotatably fit into two protruding shafts 461 that are respectively protruded inwardly from both left and right sides of the cover 46. This protruding shaft 461 has a mating piece 602.
A translucent operation cover 60 is fitted therein and is rotatable in the front and rear directions as shown by arrow A (see FIG. 7) about the support shaft.

Further, in this embodiment, support parts 441 and 442 are provided at the center and both sides of the bottom inside the holder 44, and on the support parts 441 and 442,
The support part 441 has an elastic lever-like movable piece 64 which has an approximately zero-shaped planar shape (see Fig. 9) and is bent in an inverted C-shape when viewed from the side (see Fig. 7). .4
42 as its fulcrum, and the long side end 6 of the movable piece 64.
A leg 60 extends from the operation cover 60 with emphasis on 41.
1, push and release as shown by arrow B, and press the two ends 642 on the short side of the movable piece 64 accordingly.
The actuator 562 of the two switches 56 is simultaneously pushed and released in the direction of arrow C using the actuator 562 as the point of action, thereby configuring the operation mechanism of the switch 56.

That is, the actuator 562 of the switch 56 is operated by the movable piece 64 by reversing the pressing force in the opposite direction to the pressing direction in response to the pressing operation of the operation cover 60.

Note that when pressing the operation cover 60, since the center of rotation is near the bottom, the movement is lighter when the bottom is pressed. Further, an operation cover 60 is provided on the printed circuit board 50.
A notch 501 is provided so as not to interfere with the foot 601 of the foot.

When the operating mechanism of the switch 56 is configured as described above,
In the case of this embodiment as well, the structure is simpler than that of the conventional operating mechanism, so the number of parts is reduced and it also contributes to reducing the depth L4, which will be described later.

Further, in the switch 40 with an indicator shown in FIG.
When pressing from diagonally above, change the pressing direction and operation cover 6.
Although it cannot be said that there is no possibility that the lower part of the operation cover 60 and the case 48 may rub against each other due to the movement (linear motion) direction of the operation cover 60 not matching the direction of movement (linear motion) of the operation cover 60, the lower part of the operation cover 60 may rub against the case 48, causing abrasion. If a dynamic type is used, such a fear will be completely eliminated, and it will be more preferable in terms of operability and longevity.

The reason why it is preferable to provide the reinforcing leaf spring 66 on the back side of the movable piece 64 is as described above.

Further, the number of the switch 56 may be one, and in that case, the number of the end portion 642 of the movable piece 64 may also be one.

In this switch 140 with an indicator, the printed circuit board 50 is arranged almost parallel to the front surface of the case 48 within four days of the case, and a part of it is placed outside the case four days, and the printed circuit board 50 is displayed on the front and rear surfaces of the case 48. device 52 and switch 56
For example, since the length of both terminals 521 and 561 does not affect the depth dimension, the space in the front and back direction within 4 days of the case is effectively used without waste. As in the case of the embodiment, it is possible to significantly reduce the size compared to the conventional example. Therefore,
By using the switch with indicator 140, it is possible to save space and downsize the device.

Moreover, since the printed circuit board 50 is arranged almost parallel to the front surface of the case 48, - fixed printed circuit boards 50
0, two rows (or more) can be used as the arrangement of the terminals 521 of the display 52, so even if there are a large number of terminals 521, soldering work is easy, and therefore the workability of assembly is improved.

Moreover, since only one printed circuit board is required, the cost can be reduced.

Note that a part of the printed circuit board 50 is attached to the case 4 as shown in this example.
The reason why the rear corner of the case 48 is removed (cut) and the method of cutting the cut surface 481 when the case 48 is taken out laterally from the side surface of the case 48 are as described above.

Further, the procedure for attaching the display switch 140 to the operation panel 78 is shown in FIG. 10, but since this is almost the same as in FIG. 4 above, repeated explanation will be omitted here.

Next, an example of the assembly procedure of the switch with indicator 140 is as follows.
Referring again to FIGS. 7 to 9, the reinforcing leaf spring 66 is first fitted into the bottom of the holder 44 from above.
Furthermore, the movable piece 64 is fitted from above. In that case, in this embodiment, the movable piece 64 includes a side piece 644 and a locking piece 64.
3 is provided, and a protrusion 443 is provided in the holder 44 (see FIG. 9, etc.), as well as a protrusion 443 is provided in the support portion 442 to engage with each of these to prevent floating. The support part 44 is shaped so that it can be slid into the support part 44.
1.442, and they prevent the movable piece 64 from floating up suddenly after being fitted, thereby making the assembly work very easy.

Next, a printed circuit board 50 having a display 52 and a switch 56 attached to the front and rear surfaces is fitted onto the printed circuit board 50 with a portion thereof exposed. Then, the cover 46 is placed on them from the front, and the working cover 60 is further fitted from the front. This completes the assembly.

In other words, in this switch with display 140 as well, since the parts can be inserted in order from the bottom, not only the operating mechanism but also the entire assembly is very simple, and the assembly can be easily automated.

Also in this embodiment, a flexible printed circuit board 80 may be used instead of the fixed printed circuit board 50.
An example is shown in FIG. In this example, a reinforcing plate 82 is also used, and both the front and back sides of the case are wrapped with a flexible printed circuit board 80 within four days.
The reason why this is preferable is as described above.

Furthermore, when using the flexible printed circuit board 80,
For example, as shown in FIG. 12, it may be bent along the wall inside the case 48 and a part of it may be passed between the holder 44 and the cover 46 and brought out from the rear surface of the case 48. This makes it possible to insert the case 48 into an operation panel or the like without necessarily cutting the rear corner 482 of the case 48 as in the embodiment shown in FIG.

〔Effect of the invention〕

Since the present invention is configured as described above, it has the following effects.

In other words, the printed circuit board is placed inside the case almost parallel to the front of the case, with a part of it exposed outside the case, and the display and switch are attached to the front and rear surfaces of the printed circuit board, so the front and rear inside the case are This makes effective use of space in both directions, and the depth can be reduced compared to conventional switches with indicators. Therefore, by using the switch with an indicator, it is possible to save space and downsize the device.

Moreover, for the same reason, even when using a fixed printed circuit board as a printed circuit board, there is no need to arrange the display terminals in one row and bend them 90 degrees, and multiple rows of terminal arrangements can be used with one fixed printed circuit board. become. Therefore, even if the display device has a large number of terminals, assembly workability is good, and since only one printed circuit board is required, the cost can be reduced.

Additionally, the operation cover may be able to move linearly in the front and rear directions, but if it is made to be rotatable in the front and rear directions, there will be no risk of it rubbing against the case when pressing the cover from diagonally above, improving operability and extending the service life. This is more preferable in terms of conversion, etc.

In addition, if the operating mechanism is constructed using a bent lever-like movable piece as described above, the structure will be simplified, so
This reduces the number of parts and also contributes to reducing the depth of the switch with an indicator.

Further, if a reinforcing leaf spring is further provided in the operating mechanism, the return force of the movable piece etc. can be increased.In addition, if the case is composed of a holder and a cover, and the reinforcing leaf spring is fitted into the bottom of the holder from above, If you fit the movable piece from above, you can insert the parts in order from the bottom.
Not only the operating mechanism but also the entire assembly becomes very simple, and the assembly can be easily automated.

Furthermore, if a fixed printed circuit board is used as the printed circuit board, the cost can be lower than when a flexible printed circuit board is used.

Furthermore, if a flexible printed circuit board is used as the printed circuit board, relay cables and the like can be omitted, making connection with other devices easier.

In this case, if a part of the flexible printed circuit board is exposed from the rear surface of the case, it is not necessary to remove the rear corner of the case.
