Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a multi-directional input type control switch used as an input device of a VTR, a navigation system or the like.

[0002]

2. Description of the Related Art As is well known, a multidirectional input type control switch outputs an electric signal corresponding to a tilting direction when a shaft capable of tilting in multiple directions is tilted in a specific direction. Similar to other control switches, this type of control switch is required to have a reduced number of components and a reduced size, and the following has been proposed in response to this demand.

One is a multidirectional input switch described in Japanese Patent Application Laid-Open No. 7-245042. In this switch, a pair of fixed contact pieces are arranged opposite to each other in an upper part and a lower part in a housing, and one of the pair of fixed contact pieces is divided in a circumferential direction of an operating rod, and the pair of fixed contact pieces is divided. A movable contact piece is interposed between the movable contact piece and the movable contact piece is tilted with the part as a fulcrum in a state where a part of the movable contact piece comes into contact with the upper fixed contact piece when the operating rod is tilted. Is brought into contact with the lower fixed contact piece.

Another one is a multidirectional input switch described in Japanese Patent Application Laid-Open No. 7-161259. In this switch, a distributed fixed contact and a common fixed contact are provided on the inner bottom surface of the housing, and the movable contact in the housing is urged upward by a conductive spring to respond to the operating rod when the operating rod is tilted. The movable contact piece that is tilted in contact with the dispersion fixed contact piece that is positioned in the tilting direction of the operating rod, and that the distributed fixed contact piece and the common fixed contact piece are electrically connected via the movable contact piece and the conductive spring. Thus, an electric signal corresponding to the tilting direction of the operating rod is output.

[0005]

These multidirectional input switches have the advantage that the number of components is small and the size can be easily reduced because a plurality of switching elements are eliminated from the housing. However, in the former multidirectional input switch, since the fixed contact pieces are vertically divided, it is necessary to insert-mold the contact piece members on the upper and lower parts of the housing, that is, on the body and cover constituting the housing. Therefore, two parts are required as the fixed contact member, and in this regard, the number of parts cannot be said to be small. In addition, due to the presence of two fixed contact members, the number of insert molding steps also increases. Therefore, the manufacturing cost is not necessarily low.

On the other hand, in the latter multi-directional input switch, all the fixed contacts (dispersed fixed contacts and common fixed contacts) are insert-molded on the body side, so that the number of parts is smaller than that of the former multi-directional input switch. . However, in addition to the movable contact, a spring is used to make the dispersion fixed contact and the common fixed contact conductive. For this reason, a plating process or the like is required for the spring, and the manufacturing cost increases in this regard. In addition, the presence of the spring in the conduction path increases the number of contact points, resulting in a problem of poor contact reliability.

The present invention has been made in view of such circumstances, and all the fixed contact members are insert-molded on the side of the body, and a spring is formed by using only the movable contact for conduction between the contacts. An object of the present invention is to provide an economical and highly reliable control switch that is not used.

[0008]

According to the present invention, there is provided a control switch, comprising: a body formed into a box shape; a cover attached to the body;
An operating shaft that penetrates the cover and is inserted into the body with the lower part being tilted in multiple directions around the lower part as a fulcrum, and an operating shaft that is housed in the body and tilted in accordance with the tilting operation of the shaft A first actuator that is insert-molded in the body, and a plurality of sets of fixed contact members arranged around the center line of the shaft in a state in which one set of the output contact portion and the common contact portion are adjacent to each other; A second actuator housed in the body positioned between the first actuator and a plurality of sets of output contact pieces and a common contact piece, and movable in the body housed in the body. A spring for urging the contact member toward the upper first actuator side, wherein the second actuator tilts in accordance with the tilt of the shaft, and outputs an arbitrary set of outputs at the fixed contact member. And it is configured so as to conduct during this time in contact with the piece portions and the common contact piece portion.

In order to achieve the above object, another control switch of the present invention has a body formed in a box shape, a cover attached to the body, and a lower portion penetrating the cover. An operating shaft inserted into the body and capable of tilting in multiple directions around a lower portion thereof, a first actuator housed in the body, and tilting in accordance with the tilting operation of the shaft; A plurality of fixed contact members arranged around the center line of the shaft in a state where one set of the output contact portion and the common contact portion are adjacent to each other; A second actuator housed in the body and located between the output contact part and the common contact part of the second actuator; and a second actuator in the body housed in the body. A spring that biases the first actuator side, and a movable contact member that is housed and located between the second actuator and the fixed contact member. The movable contact member is tilted in accordance with the tilt of the shaft, and the movable contact member is brought into contact with an arbitrary set of the output contact portion and the common contact portion of the fixed contact member so as to conduct therebetween.

In the control switch of the present invention, a fixed contact member having a plurality of sets of output contact portions and a common contact portion is insert-molded in the body. When the shaft is tilted, the first actuator is tilted and the second actuator is tilted correspondingly, so that a set of the output contact portion and the common contact portion located in the tilt direction of the shaft, The two actuators or the movable contact member are electrically connected to each other. Thus, despite the fixed contact piece being insert molded into the body,
Also, an electric signal corresponding to the tilting direction of the shaft is output without using a spring.

In the control switch of the present invention, as described above, the adjacent one set of the output contact portion and the common contact portion are electrically connected to each other by the second actuator or the movable contact member, thereby forming the shaft. An electric signal corresponding to the tilt direction is output. Therefore, it is necessary to surely simultaneously contact the second actuator or the movable contact member with a pair of adjacent output contact portions and the common contact portion. From this viewpoint, it is preferable to form protrusions projecting upward on the output contact portion and the common contact portion. Thereby, the contact stability of the second actuator or the movable contact member to the output contact portion and the common contact portion is improved.

It is preferable to provide an elastic member between the first actuator and the second actuator below the first actuator. This elastic member has the following two functions.

By making the elasticity of the elastic member stronger than that of the spring for urging the second actuator, the second actuator or the movable contact with respect to the output contact portion and the common contact portion can be provided when the shaft is overtilted. It is possible to prevent the contact of the members from becoming unstable.

In the control switch using the movable contact member, the elasticity of the elastic member is substantially equal to that of the spring for urging the second actuator, and
The elastic member is protruded below the second actuator through a plurality of holes provided in the second actuator corresponding to the plurality of sets of the output contact portion and the common contact portion of the fixed contact member. With the configuration in which the movable contact member below the movable contact member is pressed by the portion, a situation in which the output contact portion and the common contact portion are erroneously conducted in another group is avoided.

The shaft 30 is supported by being fitted to a hemispherical receiving portion 22 formed in the center of the lower surface of the lower surface 0 so as to be tiltable in multiple directions around the shaft 30. A projecting portion 41 is provided below the first actuator 40 so as to project outward in a flange shape. A cylindrical projection 42 is provided at the center of the lower surface of the first actuator 40, and arc-shaped projections 43 are provided on the outer surface of the projection 42 at equal intervals in the circumferential direction. . Note that the shaft 30 penetrates the inside of the first actuator 40 movably in the axial direction, and is prevented from falling off by the lowermost large diameter portion 31.

The cup-shaped second actuator 50 is
It is made of a metal having conductivity, and has an octagonal flange portion 51 corresponding to the planar shape of the body 10 as shown in FIG. Rotation is blocked. Also, the body 10
The second actuator 50 is urged upward by the spring 60 arranged along the inner surface of the wall portion being locked to the flange portion 51. The bottom plate of the second actuator 50 is provided with an opening 52 into which the protrusion 42 of the actuator 40 fits. On the inner edge of the bottom plate facing the opening 52, arc-shaped concave portions 53 in which the convex portions 43 of the protruding portions 42 are fitted are provided at equal intervals in the circumferential direction. The rotation of the first actuator 40 is blocked.

An annular elastic member 80 is interposed between the projecting portion 41 of the first actuator 40 and the bottom plate of the second actuator 50. Here, the elastic member 80 is made of rubber, and is set to have sufficiently higher spring property than the spring 60. The spring 60 is
Not only urge the actuator 50 upward, but also the first actuator 50 via the second actuator 50 and the elastic member 80.
Are elastically supported.

As shown in FIG. 6, the fixed contact piece 70 is
A first output contact portion 71 is provided at the center. A first common contact portion 72 is provided around the output contact portion 71. Around the common contact portion 72, second output contact portions 73 are provided at four positions in the circumferential direction, and four second output contact portions 73 are located on the side of the output contact portion 73. Are provided. Adjacent ones of the four output contact portions 73 and the common contact portion 74 constitute a set of four contact piece pairs A to D, and each contact piece pair is spaced at equal intervals in the circumferential direction. Are located.

The first output contact portion 71 is connected to a first output terminal portion 75 extending outward. A second output terminal 76 extends from the second output contact 73. First common contact piece 72 and second common contact piece 7
4 are connected to a common terminal 77 extending from the second common contact piece 74. Then, as shown in FIG. 7, protrusions 78 and 79 projecting upward are formed on the four output contact pieces 73 and the common contact piece 74, respectively.

Such a fixed contact piece member 70 is provided on the body 1
0, as shown in FIG. That is, the first output contact portion 71 is located at the center of the upper surface of the bottom of the body 10. The output contact portion 71 is covered with a reversing spring 90 and a key top 100. The reversing spring 90 urges the shaft 30 upward via the key top 100. A peripheral portion of the reversing spring 90 is in contact with a first common contact portion 72 located outside the output contact portion 71.
The second output contact portion 73 and the second common contact portion 74 located further outside the common contact portion 72 are one step higher than the first output contact portion 71 and the first common contact portion 72. It is at a high position and faces the lower surface of the bottom plate of the second actuator 50 at a predetermined distance. The terminal portions 75 to 77 all protrude outside the body 10 (see FIGS. 2 and 3).

Next, the operation of the control switch according to the first embodiment will be described with reference to FIG.

As the tilting direction of the shaft 30, four directions of the periphery displayed on the upper surface of the cover 20 are designated.
In each tilt direction, contact piece pairs A to D constituted by adjacent output contact pieces 73 and common contact pieces 74 are arranged.

Now, when the shaft 30 is tilted in the direction of the contact piece pair A, as shown in FIG.
The first actuator 40 tilts in the tilting direction of the shaft 30 against the urging force of the first actuator 40. Thereby, the cup-shaped second actuator 50 is tilted in the tilt direction of the shaft 30. As a result, the second actuator 50 is attached to the output contact 73 and the common contact 74 forming the contact pair A.
Contact at the same time, and the output contact portion 73 and the common contact portion 74
Are conducted. Thus, an electric signal is output from the second output terminal portion 76 corresponding to the output contact portion 73.

Here, the output contact piece 73 and the common contact piece 74 are formed with protrusions 78 and 79 projecting upward, respectively. Therefore, the second actuator 50
Reliably and simultaneously contact the output contact portion 73 and the common contact portion 74.

When the shaft 30 is tilted in the direction of the pair of contact pieces B to C, even when the shaft 30 is
The output contact 73 and the common contact 74 are electrically connected by the contact of the second actuator 50, and an output signal corresponding to the tilt direction is obtained.

When the shaft 30 is tilted with an excessive force, as shown in FIG. 8B, after the spring 60 is completely contracted on the tilt side, the elastic member 80 contracts in the thickness direction. Therefore, the displacement of the second actuator 50 and the like are avoided, and stable contact of the second actuator 50 with the output contact portion 73 and the common contact portion 74 is guaranteed. When the elastic member 80 is not used,
Since the first actuator 40 is kneaded while being in contact with the lower surface of the cover 20, the second actuator 50 may be displaced.

When the shaft 30 is pressed in the axial direction,
The shaft 30 descends against the biasing force of the reversing spring 90, and the reversing spring 90 contacts the first output contact piece 71.
As a result, conduction between the first output contact piece 71 and the first common contact piece 72 outside the first output contact piece 71, and the first output terminal section 7
5 outputs an electric signal.

Next, a control switch according to a second embodiment of the present invention will be described. In the following description, components and the like that are substantially the same as those of the control switch according to the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

As shown in FIG. 9, the control switch according to the second embodiment includes a box-shaped body 10 and a cover 2 attached to the body 10.
0, an operating shaft 30 penetrating through the cover 20, a lower part of which is inserted into the body 10, and which can be tilted in multiple directions around the lower part as a fulcrum; The first actuator 40 that inclines in response to the tilting operation of the shaft 30 and the plurality of sets of the shaft 30 are insert-molded in the body 10 in a state where one set of the output contact 73 and the common contact 74 are adjacent to each other. The fixed contact member 70 disposed around the center line, and the first actuator 50 and a plurality of sets of the output contact 73 and the common contact 74 are accommodated in the body 10. A second actuator 50 and a spring 6 housed in the body and biasing the second actuator 50 in the body toward the first actuator 40 above.
0, and a movable contact member 110 accommodated and located between the second actuator 50 and the fixed contact member 70, and the second actuator 50 includes a shaft 3
The movable contact member 110 is tilted in accordance with the tilt of 0, and the movable contact member 110 is brought into contact with an arbitrary output contact portion 73 and a common contact portion 74 to conduct electricity.

The difference between the control switch according to the second embodiment and the control switch according to the first embodiment is that the latter switches the continuity between the output contact 73 and the common contact 74 to the second. The actuator 50 is secured by simultaneously contacting the two contact pieces 73 and 74, whereas the former is provided with a movable contact piece 110 separate from the second actuator 50. 110
Are simultaneously brought into contact with the output contact portion 73 and the common contact portion 74 by the second actuator 50, so that the two contact portions 73, 74
The point is to ensure conduction.

First, as shown in FIG. 11, the movable contact piece member 110 is formed in a substantially ring shape, and is provided with four substantially quarter-arc slits 11 around a central opening 111.
2 is formed in a circular shape. This movable contact member 110
Is formed by punching a thin metal plate having conductivity. Therefore, the movable contact member 100 is easily distorted.

The movable contact member 110 is mounted on the body 10 by being placed on a shoulder 10A formed at the bottom corner of the body 10. That is, when the movable contact member 100 is simply attached to the body 10, the output contact member 7 exposed at the bottom of the body 10 is provided.
3 and the common contact 74 are in a floating state. The key top 100 is looking through the opening 111.

On the other hand, the second actuator 50
It is formed of an insulating synthetic resin or the like. The basic shape of the second actuator 50 is the same as that of the second actuator 50 used for the control switch according to the first embodiment. However, the second switch used in the control switch according to the second embodiment
Four projections 55 are formed on the rear surface side of the bottom plate portion of the actuator 50 of FIG. The projections 55 are 90
° formed at intervals. That is, the position of the projection 55 is determined so as to coincide with the tilt direction of the shaft 30. Further, the protrusion 55
Abuts between the slits 112 of the movable contact member 110.

Next, the operation of the control switch according to the second embodiment configured as described above will be described.

First, when the shaft 30 is tilted in the direction of the contact piece pair A, the first actuator 40 is tilted in the tilting direction of the shaft 30 against the urging force of the spring 60. Thereby, the cup-shaped second actuator 50 is tilted in the tilt direction of the shaft 30. as a result,
The projection 55 of the second actuator 50 is
10, the movable contact member 110 is deformed from the slit 112, so that the output contact portion 73 forming the contact pair A is formed.
The movable contact member 110 simultaneously contacts the common contact portion 74 and the output contact portion 73 and the common contact portion 74 conduct. Thus, an electric signal is output from the second output terminal portion 76 corresponding to the output contact portion 73.

The output contact 73 and the common contact 74 have projections 78 and 79 projecting upward, respectively. Therefore, the movable contact member 110 reliably and simultaneously contacts the output contact portion 73 and the common contact portion 74.

When the shaft 30 is tilted in the directions of the contact pieces B to C, even if the shaft 30 is tilted in the contact direction,
The output contact portion 73 and the common contact portion 74 are electrically connected by the contact of the movable contact member 110, and an output signal corresponding to the tilt direction is obtained.

When the shaft 30 is tilted with an excessive force, the elastic member 80 contracts in the thickness direction after the spring 60 is completely contracted on the tilting side. Therefore, displacement of the second actuator 50 and the like are avoided, and stable contact of the movable contact member 110 with the output contact portion 73 and the common contact portion 74 is guaranteed.

When the shaft 30 is pressed in the axial direction,
The shaft 30 descends against the biasing force of the reversing spring 90, and the reversing spring 90 contacts the first output contact piece 71.
As a result, conduction between the first output contact piece 71 and the first common contact piece 72 outside the first output contact piece 71, and the first output terminal section 7
5 outputs an electric signal.

In the control switch according to the second embodiment described above, the second actuator 50
Is made of an insulating synthetic resin or the like, but may be made of a conductive material. This is because the electrical connection between the output contact portion 73 and the common contact portion 74 is performed by the movable contact member 110, and thus is independent of the material of the second actuator 50.

Next, a control switch according to a third embodiment of the present invention will be described. In the following description, components and the like that are substantially the same as those of the control switch according to the first and second embodiments are denoted by the same reference numerals, and detailed description thereof will be omitted.

As shown in FIG. 12, the control switch according to the third embodiment uses a movable contact member 110 similarly to the control switch according to the second embodiment described above. Are arranged on the movable contact member 110, the structure of the second actuator 50 provided above the movable contact member 110, and disposed between the second actuator 50 and the first actuator 40 thereabove. The structure of the elastic member 80 is different from that of the control switch according to the second embodiment.

First, the second actuator 50
As in the case of the second actuator used in the control switch according to the embodiment of the present invention, it is made of conductive metal, and its basic shape is an octagonal flange portion 51 as shown in FIG. It has a cup shape having an opening 52 at the center of the bottom plate portion into which the protrusion 42 of the first actuator 40 fits. The difference from the second actuator used for the control switch according to the first embodiment is that the shaft 30 is provided around the bottom plate.
The point is that four arc-shaped holes 54 are provided corresponding to the operation directions of. In the control switch according to the first embodiment, the second actuator 5
0 is essential to be conductive. However, in the control switch according to the third embodiment, since the conductive movable contact member 110 is used, the second actuator 5
0 may be non-conductive.

On the other hand, as shown in FIG. 14, an elastic member 80 disposed between the second actuator 50 and the first actuator 40 above the second actuator 50 is fitted to the projecting portion 42 of the first actuator 40. Ring-shaped rubber sheet that is inserted into the opening 52 of the second actuator 50 with the projection 42 of the first actuator 40 in the first position.
Of the actuator 40 and the bottom plate of the second actuator 50. The annular rubber sheet has a spring force substantially equal to that of the spring 60 for urging the second actuator 50 upward, and is provided on a bottom plate portion of the second actuator 50 on a lower surface thereof. There are provided four arc-shaped projections 81 that penetrate through the four holes 54 and project below the bottom plate.

On the other hand, as shown in FIG. 15, the movable contact piece member 110 disposed below the second actuator 50 is a thin metal ring having an octagonal outer periphery fitted into the body 10. Like the movable contact member 110 used in the control switch according to the second embodiment, the inner circular opening 111 avoids interference with the protrusion 42 of the first actuator 40 and the like, and Are provided with four slits 112. The elastic member 80 penetrates the four holes 54 provided in the bottom plate of the second actuator 50 and protrudes below the bottom plate.
Are formed inside the slit 112 of the movable contact member 110 and are adjacent to the slits 112 and 11.
It comes into contact with the portion between the two from above (see FIG. 12).

Next, the operation of the control switch according to the third embodiment configured as described above will be described.

When the shaft 30 is tilted in the direction of the contact piece pair A, the first actuator 40 is turned against the biasing force of the spring 60 as shown in FIG.
Tilt in the tilt direction. As a result, the cup-shaped second actuator 50 is inclined in the direction in which the shaft 30 is inclined, and the protrusion 81 of the elastic member 80 presses the movable contact member 110 downward. The portion inside the slit 112 contacts the contact piece pair A, which conducts.

At this time, the inclination angle θ2 of the second actuator 50 is equal to the inclination angle θ of the first actuator 40.
It is smaller than 1. Because the first actuator 40 inclines by the same angle as the shaft 30 around the center of the hemispherical portion as the shaft 30 tilts,
The second actuator 50 is connected to the first
The protrusion 42 of the actuator 40 partially comes off, so that it does not completely follow the inclination of the first actuator 40, and the whole is centered on one point in the circumferential direction located on the non-operation side of the flange 51. This is because the inclination is gentle.

For this reason, the control switch according to the first embodiment in which the contact piece pair A is directly conducted by the inclination of the second actuator 50, and the movable contact member 110 is pressed and deformed by the inclination of the second actuator 50. In the control switch according to the second embodiment, in which the contact pair A is made conductive, the inclination angle θ2 of the second actuator 50 performing the pressing operation is essentially insufficient, and the inclination direction, that is, the contact The difference between the height of the second actuator 50 in the direction and the height of the second actuator 50 in the direction of the adjacent contact piece pair B and D is not sufficiently ensured. As a result, at the same time as the contact piece pair A conducts, the adjacent contact piece pair B
But there is a risk of conduction.

On the other hand, in the control switch according to the third embodiment, the elastic member 80 mounted on the second actuator 50 is inclined only by the same angle as the second actuator 50 as a whole, By being pressed from above by one actuator 40,
Since the portion of the elastic member 80 other than the protrusion 81 is compressed in the vertical direction on the operation side, the protrusion 81 projects more below the second actuator 50. For this reason, even though the inclination angle θ2 of the second actuator 50 is insufficient, the inclination angle θ3 of the protruding portion 81 that presses the movable contact member 110 is set to the second actuator 50.
Is larger than the inclination angle θ2 of the first actuator 4
A tilt angle substantially equal to the tilt angle θ1 of 0 is ensured. As a result, a large difference in height between the adjacent protrusions 81 in the circumferential direction is ensured, and there is no danger of conduction occurring between the adjacent contact pieces B and D.

Further, since the protrusion 81 is slightly compressed and deformed by pressing the movable contact member 110, the protrusion 81 is moved to the movable contact member 11 at the adjacent pair of contacts B and D.
0, the movable contact member 110
Does not come into contact with the pair of contact pieces B and D.

In the control switch according to the third embodiment, continuity in the adjacent pair of contact pieces B and D from these two surfaces is effectively avoided.

[0058]

As described above, in the control switch of the present invention, the fixed contact piece is insert-molded on the body side and is not divided into the body side and the cover side.
The number of parts is small, and the man-hour for insert molding is also small. Since the output contact portion and the common contact portion of the fixed contact member are electrically connected by the second actuator, and no spring is used for the conduction, there is no need to apply plating or the like to the spring, which also reduces the manufacturing cost. Become cheap. Also, the contact reliability is high because the number of contact points is smaller than when a spring is used for conduction. Therefore, it is excellent in both economic efficiency and reliability.

When the movable actuator is pressed by the second actuator to make contact with an arbitrary output arm and a common arm, the contact between the movable arm and the two arms is required. By reducing the gap, the amount of tilting operation of the shaft can be reduced, which is advantageous. In addition, better tilting operability can be obtained in this manner.

In the case where an elastic member is provided between the first actuator and the second actuator below the first actuator, when the shaft is overloaded and tilted, the first contact portion with respect to the output contact portion and the common contact portion is provided. It is possible to prevent unstable contact between the second actuator and the movable contact member.
