2. Description of the Related Art FIG.
2 and FIG. FIG. 12 is a longitudinal sectional view of a main part, and FIG. 13 is a transverse sectional view of a main part.

[0003] The structure of a conventional slide-type electric component includes a box 21 formed by bending a metal plate or the like and an insulating material such as a synthetic resin movably housed inside the case 21. And a pair of return springs 23 provided on both sides of the slide body 22 to urge the slide body 22 to the neutral position, and the slide body 22 held by the slide body 22. Contact piece 2 made of conductive material to be moved together with
4 and a fixed terminal 25 which is in contact with and separated from the contact piece 24, and is fixed to the insulating substrate 26 attached to the lower surface of the case 21.

[0004] A slide body 22 is provided on the top plate of the case 21.
The operation knob 22a is formed with a rectangular hole 21a which is protruded and slidably moved. Opposite sides of the rectangular hole 21a in the direction of movement of the rectangular hole 21a are spring-locked integrally inwardly of the case 21. Pieces 21b, 21b are formed. The spring locking pieces 21b, 21b and the case 2
A pair of return springs 2 between each of the two inner surfaces
3 and 23 are respectively locked.

At the center of the upper surface of the slide body 22, a square hole 2
An operation knob 22a protruding from 1a to the outside is protruded, and on both sides of the upper surface with the operation knob 22a interposed therebetween,
A slightly larger spring relief groove 22b, 22b is formed as a relief portion for the return spring 23 in the sliding movement direction from both side portions, and when the slide body 22 slides continuously from the spring relief groove 22b, 22b. A slightly smaller locking piece escape groove 22c is formed as a relief portion for the spring locking piece 21b.

A step 22d is formed at a connecting portion between the spring escape groove 22b and the locking piece escape groove 22c, and one end of a pair of return springs 23 is provided at both steps 22d, 22d of the slide body 22, respectively. By contact, the slide body 22 is urged to the center position of the case 21. When the slide body 22 is slid, the slide body 22 is moved in the sliding direction while the return spring 23 is pressed and compressed by the step 22d. At this time, the spring locking piece 21b is
By being inserted into the second locking piece escape groove 22c, the sliding movement of the slide body 22 can be surely performed without being hindered.

The operation of the slide-type electric component is such that the operation knob 22a is pressed against the urging force of the return spring 23.

The circuit 4 is also switched when the contact piece 24 comes into contact with and separates from the fixed terminal 25 as a result of the movement of the contact piece 4. When the pressing of the operation knob 22a is released from this state, the operation knob 22a returns to the original center position by the urging force of the return spring 23.

[0008]

However, in the structure of the conventional slide-type electric component described above, the pair of return springs 23 press the step 22d of the slide body 22 with the pair of return springs 23, 23 so as to abut against the spring engaging pieces 21b. It returns to the neutral position in contact with it and holds it at the neutral position, but the length between the step portions 22d and the length between the spring locking pieces 21b may be different. The length between the step portions 22d is longer than the length between the spring locking pieces 21b, and the stored return due to the variation of the spring force due to the variation of the return spring itself and the error of the bending accuracy of the spring locking piece 21b. If there is a variation in the magnitude of the spring force or a variation in the direction of the spring force due to the uneven spring length, this causes the slide body 22 (the operation knob 22a).
The return accuracy to the neutral position was deteriorated. If the length between the step portions 22d is shorter than the length between the spring engaging pieces 21b, the slide member 22 at the neutral position is thereby
Was rattling.

Accordingly, an object of the present invention is to solve the above-mentioned problems and to provide a self-return type slide-type electric component with improved return accuracy to a neutral position.

In FIGS. 1 and 3, the operation member and the return spring are shown in a state in which the operation member and the return spring are overlapped and seen through for convenience so that the engagement between the operation member and the return spring and the operation state can be clearly understood. I have.

In the figure, a case 1 is formed of an insulating material such as a synthetic resin in the shape of a box with a bottom and an open top and front, and has a horizontally long storage section 1a formed in the center. A horizontally long opening 1b is formed on the upper side of the portion 1a. The upper surface of the case 1 is formed in a gentle arc shape, and the upper surface of the opening 1b is also formed in an arc shape along the upper surface.

A pair of long grooves, which are slightly inclined along a circular arc having the same center as the circular arc on the upper surface of the general case 1 (arranged in a C-shape), are provided on both sides substantially at the center of the inner surface of the storage portion 1a. Spring storage portions 1c, 1c are formed, and the inner surfaces of the spring storage portions 1c opposed in the longitudinal direction are wall portions 1d, 1d for positioning both ends of a return spring (elastic member) 2 described later. . A connection groove 1e slightly narrower and deeper than the spring storage 1c is formed between the pair of spring storages 1c, 1c so as to connect both. Between the pair of opposed wall portions 1d, 1d of the spring storage portion 1c.
Sliding grooves 1f and 1f are formed to slide and guide a protrusion 4d of a driving body 4a to be described later.

In this case, the connecting groove 1e and the sliding groove 1
f, 1f are formed continuously in the same size,
In addition, while the spring storage portion 1c is formed linearly, the spring storage portion 1c is formed in an arc shape having the same center point as the arc shape on the upper surface of the opening 1b.

A guide groove 1g formed of an arc-shaped long groove having the same center point as that of the arc on the upper surface of the opening 1b is formed on the side surface near the inner bottom surface of the storage portion 1a. The guide groove 1g and the slide groove 1f guide and slide a guide protrusion 4e and a protrusion 4d provided on a driver 4a of the operation member 4 described later, so that the operation member 4 slides along an arc. It has to be moved. However, a predetermined clearance is formed between the two.

A pair of spring storage portions 1c, 1 of the case 1
A pair of return springs 2 and 2 made of a metal wire wound in a coil shape are stored and held in c. In this case, both ends of the return spring 2 are compressed and abut against opposing wall portions 1d and 1d of the spring storage portion 1c, and thereby both ends of the return spring 2 are positioned. It is held in the spring storage portion 1c. Further, spacers 3 made of an elastic material such as rubber are disposed on the wall portions 1d and 1d at one end where the pair of return springs 2 and 2 are disposed to face each other. One ends of the return springs 2 and 2 are pressed into contact with the wall portion 1 d via the spacers 3. Between these spacers 3,3,
A projecting portion 4d provided on a driving body portion 4a of the operating member 4 to be described later is held therebetween, and the spring force of the pair of return springs 2 and 2 is transmitted to hold the operating member 4 at the neutral position. Has become.

The operating member 4 is formed of an insulating material such as a synthetic resin, and includes a driving member 4a having a substantially rectangular planar shape and an arc-shaped flange 4b provided above the driving member 4a. It has an operating knob 4c and a receiving portion 4e for receiving one end of the return spring 2. On one side surface of the driving body portion 4a, a projection 4d having an elongated arc shape in the lateral direction of FIG. 1 is provided so as to protrude at substantially the center thereof, and the projection 4d is connected to the connection groove portion 1e of the case 1. Is engaged.
Further, both ends of the protrusion 4d are formed in a curved shape protruding outward, and the spacer 3 is elastically deformed by abutting the curved both ends with the spacer 3. Further, the distance between both ends of the protrusion 4d is formed longer than the distance between the lower wall portions 1d and smaller than the distance between the upper wall portions 1d even when the dimensions vary. ing.

As described above, the connecting groove 1 of the spring accommodating portion 1c is provided.
A spacer 3 made of an elastic material is disposed on the wall 1d on the side connected by e and is in contact with the other end of the return spring 2, and is provided on the drive unit 4a engaged with the connection groove 1e. Since the curved surfaces at both ends of the projected portion 4d are formed so as to abut against the other end of the spacer 3 to elastically deform the spacer 3, when the operation member 4 returns to the center position, the driving body portion It is possible to suppress the collision sound when the projection 4d of 4a and the end of the return spring 2 abut.

An elongated arc-shaped guide projection 4e is provided below the projection 4d at both ends of the plane so as to project in the projection direction of the projection 4d. Are slidably engaged with a guide groove 1g formed in the storage portion 1a of the case 1.

The projection 4d is engaged with the connecting groove 1e and the sliding groove 1f formed in the housing portion 1a of the case 1, and the guide projection 4e is engaged with the guide groove 1g to be slid and guided. Accordingly, the operation knob 4c is slid in an arc shape. In this case, the driving unit 4
The flat surface on which the projection 4d is provided is a sliding surface that slides on the inner bottom surface of the storage portion 1a, and the guide projection 4e and the guide groove 1g are not necessarily required, and may be formed if necessary. Good.

Further, since the pair of return springs 2 and 2 are disposed in a C-shape, the spring force of the pair of return springs 2 and 2 near the neutral position is such that the operating member 4 has an elongated arc-shaped projection. 4d, the operating member 4 is pushed upward in FIG.
The upper surface of d is moved until it contacts the inner surface on the upper side of the connection groove 1e. At this time, since the distance between the wall portions 1d is longer as going upward, the end of the return springs 2, 2 on the operating member 4 side as the operating member 4 is located upward,
It will approach the wall 1d. By the way, the maximum value of the deviation of the neutral position is, when there is a difference of the spring force more than a predetermined value,
This is the difference between the length of the projection 4d and the length between the wall portions 1d. Therefore, the end of the return springs 2 and 2 on the operation member 4 side is
d, the operating member 4 can be moved even if there is a difference in spring force between the left and right return springs 2 and 2.
Is less at the neutral position.

When the operation member 4 is positioned above, the return springs 2 and 2 (elastic members) are almost evenly elastically deformed even if the protrusion 4d is slightly longer than the connection groove 1e. The spacers 3 and 3 come into contact with the protrusion 4d and the wall 1d, and the neutral position of the operation member 4 does not shift even if there is a difference in spring force between the left and right return springs 2 and 2.

If the operation member 4 can be moved upward enough, the operation member 4 is kept in contact with the protrusion 4d and the step 1d without elastic deformation. 4 moves upward, and the neutral position of the operation member 4 does not shift even if there is a difference in spring force between the left and right return springs 2 and 2 and a difference in the amount of deformation of the elastic member.

As described above, the sliding groove portion 1f is formed in an arc shape, and the projection 4d of the driving body portion 4a is slid in the sliding groove portion 1f, thereby holding the operation knob 4c so as to be slidable in an arc shape. As a result, the sliding operation range of the operation knob 4c can be increased, and the dimension of the driving body portion 4a in the sliding direction can be reduced. Therefore, miniaturization can be performed while ensuring the operability of the operation knob 4c. It can be planned.

A slider piece 5 made of a conductive metal material is fixed to the other of the opposing planes of the driver 4a. The slider piece 5 includes a plurality of cantilevered contact pieces 5.
a is provided, and this contact piece 5a is
And a conductive pattern (not shown) provided on the substrate.

The base 6 is made of a laminated plate of phenol resin or the like, and a conductive pattern (not shown) made of a conductive material such as steel foil or carbon is formed on the surface thereof. The body is formed. An external terminal 7 made of a conductive metal plate connected to the conductive pattern by a through hole or the like is fixed to the back surface.

The base 6 has a rear surface integrally fixed to a flat cover 8 made of an insulating material such as a synthetic resin, and the conductive pattern is fixed to the driving portion 4a. The child piece 5 is attached to the case 1 so as to be in contact with and separate from the contact piece 5a. When the conductive pattern is formed with the sliding piece 5, the conductive pattern may be formed on the driver 4 a and the sliding piece 5 may be formed on the base 6. Good.

In order to assemble the slide-type electric component having the above structure, a pair of the spring storage portions 1c, 1
The spacer 3 is inserted into the wall portions 1d and 1d at one end of the spacer c, and the return spring 2 is inserted with one end of the spacer 3 in contact with the other end of the spacer 3.

Next, the connecting groove 1e and the guide groove 1f provided in the storage section 1a of the case 1 are provided with the protrusion 4d provided on the sliding surface of the driving body 4a of the operating member 4. The guide protrusions 4e are inserted into each other to overlap each other, and the base 6 provided with a conductive pattern is integrally fixed on the slider piece 5 fixed on one side opposite to this. The assembly is completed by covering the cover 8 and attaching it by a method such as caulking or bonding.

As described above, the driving body portion 4a of the operating member 4 has a sliding surface on which the projection 4d is formed and one side surface to which the slider piece 5 is fixed, facing front and back. After attaching the spacer 3 and the return spring 2 to the spring storage portion 1c of the case 1, the sliding surface of the operation member 4 provided with the protrusion 4d is lowered. If the cover 8 in which the base 6 provided with the conductive pattern is fixed to the ladle is attached from above, the assembly is completed,
Assembling is simplified and workability is improved.
Further, since the conductive pattern can be formed in a flat surface shape, which is one side surface of the driver 4a, the conductive pattern can be easily formed.

Next, the operation of the slide-type electric component having the above-described structure will be described with reference to FIGS.

First, in the initial state shown in FIG. 1, the operation member 4 (operation knob 4c) is in the neutral position. In this state, the projection 4d of the driving body 4a is inserted into the connection groove 1e, Both ends of the portion 4d abut on the pair of spacers 3, 3, and the operating knob 4c is held at the neutral position by the urging force of the pair of return springs 2, 2 via the pair of spacers 3, 3.

At this time, the biasing forces of the pair of return springs 2 and 2 are in a state of being kept in equilibrium.
Since the distance between both ends is longer than the distance between the lower wall portions 1d, the play of the operation knob 4c at the neutral position is suppressed.

The operation members 4 are returned by the return springs 2 and 2.
Is pushed upward, and both spacers 3, 3 come into contact with the projection 4d and the wall 1d, so that they are located at the predetermined neutral position.

From this state, for example, as shown in FIG.
When the operation knob 4c is pressed leftward in the figure, the operation knob 4c is pressed.
c is slid to the left, and accordingly, the driving body 4a is slid and guided to the left by the protrusion 4d being guided by the slide groove 1f and the guide protrusion 4e being guided by the guide groove 1g. It is slid in an arc. With this sliding movement, the left end of the protrusion 4d compresses the return spring 2 via the spacer 3 against the urging force of the return spring 2 disposed on the left side. With this sliding movement, the contact piece 5a of the slider piece 5 slides on the surface of the base 6 and comes into contact with the conductive pattern, so that the contact is turned on, and the signal is transmitted to the external circuit via the external terminal 7. It is to be sent. On the other hand, the right return spring 2 is housed in the right spring housing 1c as shown in FIG.
One end of the right return spring 2 on the operation member 4 side (the part that actually contacts the right spacer 3) is a protrusion 4d of the operation member 4.
Away from the right edge of the

At this time, in the driving body portion 4a, the protrusion 4d is slid in an arc shape along the arc-shaped sliding groove portion 1f.
The spring storage portions 1c, 1c corresponding to f are formed in a straight line. As described above, the return spring 2 is disposed in each spring storage portion 1c so as to be linear, and the approximate return spring 2 is formed along the arc-shaped sliding movement direction of the protrusion 4d. When the portion 4d slides along the sliding groove 1f in an arc shape, the return spring 2 bends linearly. As described above, when the protrusion 4d slides along the sliding groove 1f in an arc shape, the return spring 2 is bent in a straight line, so that the return spring 2 can be used in a straight line. Since a load is applied vertically to the end face of the return spring 2, it is not kinked, and an abnormal load is not applied to the projection 4 d, so that the operation of the operation member 4 is stabilized and a secure return is obtained. ing. When performing the operation of pressing in the sliding direction from the neutral position, the operation knob 4c slightly moves downward, but the movement is in the width direction of the resistor, and the contact comes from the end of the resistor. Since the distance to the piece 5a does not change, the output hardly changes.

When the pressing of the operation knob 4c is released from the state shown in FIG. 3, the biasing force of the left return spring 2 in which the driving body portion 4a is compressed while being urged upward by the return springs 2,2. As a result, it returns to the neutral position shown in FIG. At this time, the right end of the projection 4d comes into contact with the right spacer 3 urged by the return spring 2 disposed on the right, and the generation of collision noise is suppressed by the elastic deformation of the spacer 3 at this time. It is something that can be done.

In the vicinity of the neutral position, the urging force of the pair of return springs 2, 2 is applied from slightly below both ends of the elongated arc-shaped projection 4d of the operation member 4, and the operation member 4 is moved upward in FIG. (In the direction perpendicular to the sliding movement direction), and is moved until the upper surface of the projection 4d comes into contact with the upper inner surface of the connection groove 1e. Further, when the protrusion 4d is pushed upward, the wall 1d is disposed so as to be inclined. Therefore, even if the protrusion 4d protrudes from the wall 1d, the protrusion 4d is gradually retracted, and the return spring 2 is closer to the operation member 4 side. Are in contact with the walls 1d of the case 1 (actually via the spacers 3) to reliably position the operation member 4 at the neutral position. Thereby, the operation member 4 has no backlash in the sliding movement direction, and therefore, the return accuracy can be increased.
Incidentally, even when the operation knob 4c is pressed rightward in the figure, the operation is the same as described above, and the description is omitted here.

In the first embodiment, the operation knob 4c and the drive unit 4d are configured to slide in an arc shape. However, the present invention is not limited to this. It may be configured to slide in a straight line (this example will be described in a second embodiment described later). In this case, the same effect can be obtained.

Although the conductive pattern has been described as a resistor and a current collector to constitute a slide type variable resistor, the conductive pattern may be formed by a switch pattern which is turned on and off to form a slide type switch. Also, the slider piece 5
The arrangement of the conductive patterns may be reversed, or they may be provided on the side surface of the driving body portion 4a facing the replacement knob 4c.

The return spring 2 is formed by a coil spring,
Since the return spring 2 is arranged in a U-shape and the case portion in contact with the case is also U-shaped, the return spring 2
It is possible to smoothly move the operation member 4 in a direction perpendicular to the movement direction without twisting.

Further, since the spacer 3 is interposed between the return spring 2 and the operation member 4, the operation member 4 can be smoothly moved in the direction perpendicular to the sliding direction of the operation member 4 without being affected by the end face shape of the return spring 2. And the return spring 2 is more effective when the return spring 2 is formed by a coil spring.

Further, since the operation member 4 is stored in the case 1 so as to move in an arc, the return spring 2 does not become large even if it is lengthened, so that it can be small and can cope with a long stroke. Further, since the return spring 2 is in contact with the operation member 4 on the vertical plane, the return can be smoothly performed.

According to the first embodiment, the driving member 4a of the operating member 4 projects in the direction perpendicular to the sliding direction and engages with the other end of the pair of return springs 2, 2. A projection 4d is formed, and a pair of spring housings 1c, 1c are formed in the housing 1a of the case 1 in a row along the sliding direction below the sliding image of the driver 4d. A connecting groove 1e for connecting both is formed between the pair of spring housings 1c, 1c, and the projections of the driver 4a are formed in the pair of spring housings 1c, 1c continuously to the connecting groove 1e. Since the sliding groove portion 1f for slidingly guiding the 4d is formed, the spring storage portion 1c in which the return spring 2 is disposed is formed in parallel with a position overlapping the driving body portion 4a of the operation member 4. The return spring 2 is connected to the sliding direction of the driving body 4a. Driver unit compared to the arrangement structures 4
Since the dimension of a in the sliding direction can be reduced, the size of the entire electric component can be reduced.

Although the spacer 3 is interposed in the first embodiment, it is not always necessary. In this case, the ends of the return springs 2 and 2 on the operation knob 4c side are connected to the projections 4d. Since it comes into contact with and comes close to the wall 1d, the return accuracy at the neutral position can be similarly increased.

Next, a second embodiment of the present invention will be described with reference to FIGS.
This will be described with reference to FIG. 8 to 11 show a slide-type electric component according to a second embodiment, FIG.
9 is an enlarged explanatory view of a main part of FIG. 8, FIG. 10 is a cross-sectional view of an essential part, and FIG. 11 is an enlarged explanatory view of a main part of FIG. Note that this second
This embodiment is the same as the prior art examples of FIGS. 12 and 13 described above except for the points described below, and therefore, detailed description other than the features of the present invention is omitted.

In the second embodiment, the spring relief groove 22b and the locking piece relief groove 22c of the slide body 22 as the operating member are provided.
A stepped portion is formed at the connecting portion with the tapered portion 30 which projects upwardly and thus outwardly. The upper portion of the tapered portion 30 projects toward the respective return springs 23 from the spring locking pieces 21b at the neutral position of the slide body 22.
Therefore, one end of the pair of return springs 23 on the side of the slide body 22 projects from the spring engaging piece 21b.
, And urges the slide body 22 toward the center position of the case 21. At this time, the slide body 22
Since there is a gap originally in the direction perpendicular to the sliding movement direction, the slide body 22 is pushed up by the return springs 23, 23 on both sides in the direction perpendicular to the above (upward direction in FIG. 8), so that the return springs 23, 23 slide. One end of the body 22 is in contact with each of the spring retaining pieces 21b, 21b.
As a result, the slide body 22 is positioned at the neutral position shown in FIG.

As described above, the tapered portions 30, 30 are provided on both sides of the slide body 22, and the long portions of the tapered portions 30, 30 are longer than the distance between the spring engaging pieces 21b, 21b of the case 21, and are short. Is shorter than the space between the spring engaging pieces 21b of the case 21.

The tapered portion 30 may be formed by an arcuate surface, so that the operation member (22) can smoothly move in a direction perpendicular to the sliding direction of the operation member (22). .

The second embodiment has the same operation and effect as the first embodiment.

In the first embodiment, a coil spring is used as the return spring, and a tapered surface is provided in a portion where the end of the return spring on the operation member side comes into contact. In the case where a rubber, a leaf spring, or the like is used as the return spring, the surface shape provided on the operation member of the return spring may be tapered. In this case, the surface of the return spring that comes into contact with the wall 1d is used. Need not be the same plane as this plane, and may be a perpendicular plane.

[0059]

As described above, according to the present invention,
Even if the distance between the abutting portions on the case side where the ends of the elastic members abut and the distance between the abutting portions of the operating members where the ends of the elastic members abut on the operating member are different, the operating member is The elastic member moves the operating member in a direction orthogonal to the sliding movement direction of the operating member until the operating member comes into contact with the case, so that the difference in length between the two members is reduced, so that the return accuracy can be increased.

Further, according to the present invention, since the elastic member is formed of a coil spring, the coil spring is arranged in a C shape, and the case portion for accommodating the coil spring is also formed in a C shape, so that the coil spring is not twisted and smooth. It is possible to move the operating member in a direction orthogonal to the moving direction.

Further, according to the present invention, since the tapered surface is formed by the arc surface, the operating member can be smoothly moved in the direction orthogonal to the moving direction of the operating member.

According to the present invention, since the spacer is interposed between the elastic member and the operating member, the operating member smoothly moves in the direction perpendicular to the moving direction of the operating member without being affected by the shape of the end surface of the elastic member. Can be moved, and it is more effective when the elastic member is formed by a coil spring.

Further, according to the present invention, since the operation member is provided so as to slide in an arc shape, the operation member can be small and can cope with a long stroke. In addition, since the coil spring contacts the operation member on the vertical plane, the coil spring can be smoothly returned.
