In addition, the engagement state of the holding | maintenance protrusion of a cover and a return spring is also shown by the dotted line.

In the figure, the casing 1 is formed in the shape of a bottomed box having an upper surface and a front surface opened by an insulating material such as a synthetic resin, and in the center is formed an accommodating portion 1a having a long side shape. Similarly, the laterally long opening 1b is formed above the lead portion 1a. Moreover, the upper surface of the said casing 1 is formed in the gentle arc shape, and the upper surface of the said opening part 1b is also formed in the arc shape along this.

A pair of spring storage portions, each of which consists of long grooves in a slightly inclined state along an arc having the same center as the arc of the upper surface of the casing 1, approximately at the center of the inner bottom of the housing portion 1a. 1c and 1c are formed, and the inner side edge part of this spring storage part 1c becomes wall part 1d, 1d which positions both ends of return spring 2 mentioned later. have. Further, between the pair of spring storage portions 1c and 1c, a connection groove portion 1e that is slightly narrower in width than the spring storage portion 1c and has a bottom is formed so as to connect both sides. Sliding groove part which pulls in the projection part 4d of the drive body part 4a mentioned later between the pair of said wall parts 1d and 1d which oppose the said spring storing part 1c successively to the connection groove part 1e. (1f, 1f) are formed.

In this case, the connecting groove portion 1e and the sliding groove portions 1f and 1f are continuously formed in the same size, and the spring housing portion 1c is formed in a straight shape, whereas the upper surface of the opening portion 1b is formed. It is formed in the shape of an arc having the same center point, following the arc shape of.

Moreover, the guide groove part 1g which consists of an arc-shaped elongate groove is formed in the lower side of the inner bottom face of the said accommodating part 1a similarly. This guide groove 1g is also formed in the shape of an arc having the same center point along the arc of the upper surface of the opening 1b. This guide groove 1g and the sliding groove 1f guide and slide the guide protrusions 4e and the projections 4d formed on the drive body portion 4a of the operation member 4, which will be described later. ) Slides along the arc.

A pair of return springs 2 and 2 made of a metal wire wound in a coil shape are arranged in the pair of spring storage portions 1c and 1c of the casing 1. In this case, both ends of the return spring 2 are positioned at the wall parts 1d, 1d, which are opposite inner edge portions of the spring storage part 1c, whereby the return spring 2 is provided with the spring storage part 1c. It is supposed to be maintained in). Further, a spacer 3 made of an elastic material such as rubber or the like is disposed in the wall portion 1d on one end side where the pair of return springs 2 and 2 are disposed to face each other. The projections 4d formed on the drive body portion 4a of the operation member 4 described later are sandwiched between the spacers 3, 3, and the operation member 4 is held at the neutral position.

The operation member 4 is formed of an insulating material such as synthetic resin, and has a driving body portion 4a having a substantially rectangular plane, and an arc-shaped blade portion 4b provided above the driving body portion 4a. It is formed by the operation knob 4c. On one plane facing the front and back of the drive body portion 4a, a projection 4d having an elongated arc shape protrudes and is formed at an approximately center, and the projection 4d is a housing portion of the casing 1. It engages with the said connection groove part 1e formed in 1a). Moreover, the both ends of the said projection part 4d are formed in the curved shape which protrudes outward, and this curved surface is made to elastically deform the spacer 3 by contacting the said spacer 3.

Thus, the said spacer 3 which consists of an elastic material which abuts on the other end side of the said return spring 2 is in the said wall part 1d of the side which is connected by the said connection groove part 1e of the said spring storing part 1c. Arranged and curved surfaces of both ends of the protrusion 4d formed in the drive body 4a engaged with the connecting groove 1e are in contact with the other ends of the spacer 3 so that the spacer 3 is elastic. Since it is formed so that it may deform | transform, it suppresses the collision sound when the projection part 4d of the said drive body part 4a and the edge part of the return spring 2 abut when the said operation member 4 returns to a center position. It is possible to do. In addition, even if there is a difference in the length of the protrusion 4d and the connecting groove 1e, since the operation member 4 does not rattle from the center position, the return accuracy of the operation member 4 is increased. It is possible to increase.

Further, below the protrusion 4d, a guide protrusion 4e, which is formed in an elongated arc shape over both ends of the plane, also protrudes in the protruding direction of the protrusion 4d, and this guide protrusion 4e is formed. Is slidably engaged with the guide groove portion 1g formed in the housing portion 1a of the casing 1.

The projection portion 4d is engaged with the connecting groove portion 1e and the sliding groove portion 1f formed in the housing portion 1a of the casing 1, and the guide protrusion portion 4e is provided with the guide groove portion 1g. The operation knob 4c is operated to slide in an arc shape by being engaged with and engaging with it. In this case, the plane in which the protrusion 4d of the drive body portion 4a is formed is a sliding surface that slides with the inner bottom surface of the housing portion 1a, and the guide protrusion 4e and the guide groove portion 1g. Is not necessary and may be formed as needed.

In this way, the sliding groove 1f is formed in an arc shape, and the projection 4d of the drive body 4a is slid into the sliding groove 1f to slide the operation knob 4c in an arc shape. Since the slide operation range of the operation knob 4c can be increased while the size of the sliding direction of the drive body portion 4a can be reduced, the operation knob 4c can be maintained. It is possible to miniaturize while ensuring the operability of the.

Moreover, the sliding member 5 which consists of electroconductive metal materials is fixed to the other plane which opposes the said drive body part 4a. A plurality of cantilever-type contact pieces 5a are provided in the sliding piece 5, and the contact pieces 5a are formed with conductive patterns 6a and 6b formed in a base die 6 described later. Contact and separation.

The base die 6 consists of laminated boards, such as a phenol resin, and the conductive patterns 6a and 6b which consist of electrically conductive materials, such as copper foil and carbon, are formed in the surface. Moreover, the external terminal 7 which consists of an electroconductive metal plate connected by the said conductive patterns 6a and 6b and the through hole etc. is fixed to the back surface.

The base die 6 has a flat cover 8 made of an insulating material such as synthetic resin, except for a part of the surface portion on which the conductive patterns 6a and 6b are formed and a part of the lead portion of the external terminal 7. It is integrally molded. The cover 8 is in the state in which the conductive patterns 6a and 6b are in contact with and spaced apart from the contact piece 5a of the sliding member 5 fixed to the drive member 4a. It is attached so that the opening part 1a of the casing 1 may be covered.

On the other hand, in the case of forming the sliding piece 5 and the conductive pattern, the conductive patterns 6a and 6b are formed in the driving body portion 4a, and the sliding piece (in the base die 6). 5) may be formed.

In addition, the cover 8 protrudes in the direction of the housing portion 1a of the casing 1, and is provided with the return spring formed on the inner side edge portions of the pair of spring storage portions 1c and 1c. A pair of retaining protrusions 8a and 8a extending to the vicinity of the wall portions 1d and 1d for positioning both ends of (2) are formed. One end of the retaining protrusions 8a and 8a on the side opposite to the side of the return spring 2 engaging with the protrusion 4d of the operation member 4 of the return spring 2 is stopped by the spring storing portions 1c and 1c. It is formed only at the side, and is arrange | positioned in contact with or close to the one end side of the said return spring 2 accommodated in the spring storage part 1c of the said casing 1.

In order to assemble the slide type electric component of the above configuration, the spacer 3 is inserted into the wall portions 1d and 1d on one end side of the pair of the spring storage portions 1c and 1c of the casing 1. Then, the return spring 2 is inserted in the state where the one end side is in contact with the other end side of the spacer 3.

Next, the protruding portion formed on the sliding surface of the drive body portion 4a of the operating member 4 in the connecting groove portion 1e and the guide groove portion 1g formed in the housing portion 1a of the casing 1. The base on which the conductive patterns 6a and 6b are formed on the sliding piece 5 which is overlapped by inserting the 4d and the guide protrusion 4e into the opposite side and fixed to one side opposite to this. The die 6 covers the cover 8 in which the die 6 is integrally molded, and the cover 8 covers the opening of the housing portion 1a of the casing 1 by a caulking or bonding method. Assembly is completed by mounting.

In this manner, the driving surface 4a of the operating member 4 is formed such that the sliding surface on which the protrusion 4d is formed and the one side surface on which the sliding member 5 is fixed are formed to face each other. Therefore, after attaching the spacer 3 and the return spring 2 to the spring storing portion 1c of the casing 1, the sliding surface on which the protrusion 4d of the operating member 4 is formed is Since the assembly is completed by mounting the cover 8 on which the base die 6 having the conductive patterns 6a and 6b formed thereon is integrally fixed and molded from above from above, the assembly is completed. It becomes simpler, and workability is improved. In addition, since the conductive patterns 6a and 6b can be formed in a flat surface shape, which is one side of the drive body portion 4a, the conductive patterns 6a and 6b can be easily formed.

Further, the operation member 4 and the return spring 2 are accommodated in the housing portion 1a of the casing 1, and are laminated so as to cover the opening side of the housing portion 1a with the cover 8. Since it is possible to assemble from one direction, the workability is improved, and the mold can be prevented from moving or falling out of the return spring 2 with a simple structure without having a complicated structure.

In addition, when the retaining projection 8a is always formed in contact with one end side of the return spring 2, this one end side is a fixed side of the return spring 2 which is not driven unlike the other end side. The return spring 2 can be firmly supported by the spring storing portion 1c. In addition, such solid support can be easily set simply by appropriately setting the dimensions in the one-way assembling process.

Next, the operation | movement of the slide type electric component of the said structure is demonstrated with reference to FIG.

First, in the initial state shown in FIG. 1, the operation knob 4c is in a neutral position, and in this state, the protrusion 4d of the drive body portion 4a is engaged with the connecting groove 1e, and the protrusion Both ends of 4d are in contact with the pair of spacers 3 and 3 and are held in a neutral position by the elastic force of the pair of return springs 2 and 2.

At this time, the elastic force of the pair of return springs 2, 2 is in a balanced state of support, and the curved surfaces of both ends of the projections 4d press the spacers 3, 3 to elastically deform. The ratcheting of the operation knob 4c at the neutral position is suppressed. In this state, the contact piece 5a of the sliding piece 5 and the conductive pattern 6a are in contact with each other, but the contact piece 5a and the conductive pattern 6b are separated from each other.

In this state, for example, as shown in Fig. 3, when the operation knob 4c is pressed in the left direction in the drawing, the operation knob 4c is slidably moved to the left, and accordingly the drive body portion ( 4a), the projection portion 4d is slid into the sliding groove portion 1f and the guide protrusion portion 4e is slid into the guide groove portion 1g so as to slide to the left side, and the projection portion 4d is moved to the left side. The return spring 2 is compressed by resisting the elastic force of the return spring 2 disposed on the return spring 2. At this time, the contact piece 5a of the sliding element 5 is brought into contact with the conductive pattern 6b by sliding on the surface of the base die 6 so that the contact is turned on so that the signal is turned on the external terminal. It is to be transmitted to an external circuit via (7).

At this time, the driving body portion 4a is configured to slide the projection portion 4d in an arc shape along the sliding groove portion 1f formed in an arc shape, but corresponds to the arcuate sliding portion 1f. The spring storing portion 1c is formed in a straight line shape, and is arranged in the spring storing portion 1c such that the return spring 2 is in a straight line, and the return spring 2 is approximately the protrusion 4d. Since the protruding portion 4d slides the sliding groove portion 1f in an arc shape, the return spring 2 is bent in a linear shape because it is formed along the slide direction of the arc shape.

In this way, since the return spring 2 is bent in a straight line when the protrusion 4d slides the sliding groove 1f in an arc shape, the return spring 2 can be used as it is. In addition, since the load is applied perpendicularly to the end face of the return spring 2, the warp is eliminated, and since the abnormal load is not applied to the protrusion 4d, the operation member 4 The operation of is stable and a reliable return can be obtained.

Further, when the return spring 2 is bent, since the retaining projection 8a extending to the cover 8 abuts or comes close to one end side of the fixed side, the return spring 2 Is securely supported, and even if an excessive force is applied to the return spring 2 when the projection 4d slides the sliding groove 1f in an arc shape, the return spring 2 ) Is prevented from moving or popping out.

In this state, when the pressurization to the operation knob 4c is released, the drive body portion 4a is returned to the neutral position shown in FIG. 1 by the elastic force of the return spring 2. At this time, the protrusion 4d is brought into contact with the spacer 3 on the right side that is elastically supported by the return spring 2 disposed on the right side, and the elastic deformation of the spacer 3 at this time occurs. It is possible to suppress the occurrence of collision sounds. Incidentally, even when the operation knob 4c is pressed in the right direction in the drawing, the same operation as described above is performed, and therefore the description thereof is omitted here.

On the other hand, in the above embodiment, the operation knob 4c and the driving body portion 4d are configured to slide in an arc shape. However, the present invention is not limited thereto, and is configured to slide, for example, in a linear shape. In this case, of course, the same effect can be obtained.

In addition, although the conductive pattern was described as a switch pattern to be in an on state and an off state, it was configured as a slide type switch. However, the conductive pattern may be formed of a resistor and configured as a slide type variable resistor. In addition, the arrangement of the sliding member 5 and the conductive patterns 6a and 6b may be reversed, and they may be formed on the side surface of the driving body portion 4a that faces the operation knob 4c.

According to the above embodiment, the projection 4d of the operating member 4 is protruded in a direction orthogonal to the sliding direction to form the protrusion 4d engaging with the other end side of the return spring 2. At the same time, in the cover 8, the holding projections 8a which are arranged in contact with or close to one end side of the return spring 2 housed in the housing portion 1a of the casing 1 are formed. Therefore, assembling can be performed from one direction, and workability is improved, and the mold can be prevented from moving or falling out of the return spring 2 as a simple structure without having a complicated structure.

In addition, a pair of said return springs which hold | maintains the said return spring 2 at both ends of the accommodating part 1a of the said casing 1, and elastically supports the said operation member 4 to a center position ( Also in the case of 2), the return spring 2 is arranged in parallel with the drive body portion 4a of the operating member 4 in the housing portion 1a of the casing 1. Since the spring accommodating part 1c can be formed, the dimension of the sliding direction of the drive body part 4a is compared with the structure which arrange | positions the return spring 2 successively in the sliding direction of the said drive body part 4a. Since it can shorten, the size of the whole electric component can be made small.

As described above, the slide-type electrical component of the present invention includes a casing having an accommodating portion opened on one side, an operating member and a driving body portion, and an operation member in which the driving body portion is slidably arranged in the accommodating portion of the casing; One end of the casing is stopped and the other end of the casing has a return spring for elastically supporting the operation member to an initial position, a sliding member piece or a conductive pattern provided on one side of the driving body part, and the sliding piece piece or the conductive pattern A conductive pattern or sliding piece provided opposite to the cover, the cover being integrally engaged to cover the housing of the casing, and protruding in a direction perpendicular to the sliding direction to the driving body portion of the operation member, the other end side of the return spring. And a protruding portion to be engaged with each other, and at the same time, the cover has a holding protrusion which is disposed in contact with or close to one end side of the return spring accommodated in the housing portion of the casing. Since it is formed, assembling from one direction is possible, and workability is improved, and it is possible to prevent the return spring from moving or falling off with a simple structure without making the mold into a complicated structure.

In addition, the return spring is composed of a pair of return springs, one end of which is stopped at both sides of the housing part of the casing and elastically supports the operation member to the central position, and the housing part of the casing is lower than the sliding surface of the driving body part. Along the sliding direction to form a pair of spring storing portions having wall portions at which both ends of the return spring are positioned, and forming a connecting groove portion connecting both sides between the pair of spring storing portions, Since the sliding groove part which pulls in the projection part of a drive body part continuously between the pair of opposing wall parts of a storage part is formed continuously, in parallel with the drive body part of an operation member, the accommodating part of a return spring can be formed, Compared with the structure in which the return springs are arranged in succession in the sliding direction of the driving body, the dimensions of the sliding direction of the driving body can be shortened. It is possible to reduce the size of the entire product.                     

In addition, the driving member of the operation member is formed by opposing the sliding surface on which the protrusion is formed and the one side surface on which the sliding member piece or the conductive pattern is formed, so that the return spring is mounted on the spring storage portion of the casing. Since the assembly is completed by stacking the sliding surface of from above and attaching the base die from above, the workability of assembly is simplified, and the conductive pattern can be formed into a flat surface shape, making formation easy.

In addition, the sliding groove portion is formed in an arc shape, and the projection part of the driving body is slid into the sliding groove portion, so that the operation knob can be slide-activated in an arc shape, thereby increasing the slide operation range of the operation knob. Since the dimension of the sliding direction of a drive body part can be made small, miniaturization can be aimed at with operability.

In addition, when the spring receiving portion corresponding to the arcuate sliding groove portion is formed in a straight shape, and the return spring is arranged in a straight line in the spring storing portion, the return spring is linear when the projection portion slides the sliding groove portion in an arc shape. Since the return spring can be used in a straight line, the warpage is eliminated, and abnormal load is not applied to the projection, so that the operation is stable and reliable return is possible.
