Description

The present invention relates to a switch device that switches between an energized on state and an energized off state.

A push switch is known as a switch device that switches between an energized on state and an energized off state in conjunction with a user's operation and lever movement. The conventional push switch shown in FIG. 12 (see, for example, Patent Document 1) includes a base portion 2 and a movable contact member 3 housed in a cylindrical housing 1. The base portion 2 is arranged at the center of the housing 1, and the movable contact member 3 has a lateral U-shape and is arranged so as to sandwich the base portion 2. The movable contact member 3 is made of a spring-like member, is urged in a direction sandwiching the base 2, and the base 2 is made of resin. Further, the push switch includes a push button 4 which is partially housed in the housing 1, and the push button 4 is separated from the base 2 via a movable contact member 3 by a return spring 5 arranged in the base 2. Is urged to protrude from the housing 1.

When the push button 4 is not pushed by the user but is only urged by the return spring 5, as shown in FIG. 12 (A), the sliding portion 3a, which is a narrow portion of the movable contact member 3, is the protrusion 2a of the base 2. As a result, the contact portion 3b, which is the end portion of the movable contact member 3, does not come into contact with the fixed contact member 6 provided on the base portion 2. As a result, the energization via the movable contact member 3 and the fixed contact member 6 is turned off.

Further, when the push button 4 is pushed by the user in the direction indicated by the arrow, as shown in FIG. 12B, the push button 4 moves the movable contact member 3, and the sliding portion 3a is displaced from the protrusion 2a and narrowed. , The contact portion 3b approaches the base portion 2 and comes into contact with the fixed contact member 6. As a result, the energization via the movable contact member 3 and the fixed contact member 6 is turned on.

Japanese Unexamined Patent Publication No. 2005-78852

By the way, in the push switch described above, when the push button 4 is pushed in, the sliding portion 3a moves while rubbing against the protrusion 2a of the base portion 2, so that friction powder 7 may be generated from the sliding portion 3a and the protrusion 2a. be. The friction powder 7 is urged by the movable contact member 3 and scatters along the moving direction of the movable contact member 3 (push button 4). In the push switch described above, since the sliding portion 3a and the contact portion 3b of the movable contact member 3 are arranged in a straight line with respect to the moving direction of the movable contact member 3, the friction powder scattered along the moving direction of the movable contact member 3 7 may enter between the contact portion 3b and the fixed contact member 6 to prevent the contact portion 3b and the fixed contact member 6 from coming into contact with each other, resulting in contact failure (FIG. 12 (B)).

Further, when the push switch is used as a switch for a brake lamp, for example, a large current flows through the movable contact member 3, so that the contact portion 3b generates heat. On the other hand, when the movable contact member 3 is miniaturized in response to the demand for miniaturization of the push switch, the sliding portion 3a and the contact portion 3b come close to each other, so that the heat of the contact portion 3b can be easily transferred to the sliding portion 3a. When the sliding portion 3a comes into contact with the protrusion 2a of the fixed contact member 6, the protrusion 2a may be thermally deformed and crushed. In this case, the protrusion 2a may not be able to sufficiently spread the sliding portion 3a, and the contact portion 3b may remain in contact with the fixed contact member 6 to cause insulation failure.

An object of the present invention is to provide a switch device capable of suppressing the occurrence of contact failure and insulation failure.

In order to achieve the above object, the switch device of the present invention includes a first contact member and a second contact member, and the first contact member and the second contact member relatively move and slide. In a moving switch device, the first contact member and the second contact member are provided with a separating portion for separating the first contact member from the second contact member when the first contact member and the second contact member move relative to each other. The contact member 1 has a sliding portion that slides and engages with the separation portion and a contact portion that comes into contact with the second contact member. The sliding portion and the contact portion are arranged apart from each other in a second direction orthogonal to the first direction in which the contact member and the second contact member move relatively.

According to the present invention, in the first contact member, the sliding portion and the contact portion have a sliding portion and a contact portion in a second direction orthogonal to the first direction in which the first contact member and the second contact member move relatively. Since they are arranged apart, the sliding portion and the contact portion are not arranged in a straight line with respect to the first direction. As a result, even if the friction powder generated by the sliding of the sliding portion and the separating portion scatters along the first direction, it is difficult for the friction powder to enter between the contact portion of the first contact member and the second contact member. As a result, the occurrence of contact failure can be suppressed. Further, in the second direction, since the sliding portion and the contact portion are arranged apart from each other, the heat of the contact portion is not easily transferred to the sliding portion, and the separated portion engaged with the sliding portion undergoes thermal deformation. It is possible to prevent the contact portion of the first contact member from remaining in contact with the second contact member by suppressing the raising and crushing. As a result, the occurrence of insulation defects can be suppressed.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view schematically showing the appearance of a push switch as a switch device according to the present embodiment. In FIG. 1, the push switch 10 includes a substantially cylindrical central case 11, a substantially cylindrical front case 12, a substantially cylindrical base portion 13, and a shaft 14. The front case 12 is arranged coaxially with the central case 11 and is arranged at one end of the central case 11. The base portion 13 is arranged so as to be coaxial with the central case 11 and inserted from the other end of the central case 11. The shaft 14 has a substantially columnar protrusion 14a having a hemispherical tip. The shaft 14 is arranged coaxially with the central case 11, and is substantially entirely housed in the central case 11 and the front case 12 so that the protrusion 14a projects from the end of the front case 12. A conical rubber seal 15 is arranged between the protrusion 14a and the front case 12.

In the push switch 10, the central case 11 is in a direction orthogonal to the central axial direction (hereinafter, simply referred to as "axial direction") (first direction) of the central case 11 from the side (hereinafter, referred to as "width direction"). It has two snap-fit portions 11a that project with respect to (second direction). The push switch 10 is attached to, for example, a vehicle by inserting and engaging these snap-fit portions 11a into mounting holes provided in a panel, frame, or the like of the vehicle.

2 and 3 are views schematically showing the configuration of the push switch 10 in a state where the central case 11, the front case 12, and the rubber seal 15 are removed, and FIG. 2 (A) is a perspective view of the push switch 10. 2 (B) is a plan view of the push switch 10, and FIG. 3 is a cross-sectional view taken along line III-III in FIG. 2 (B). In each figure, the Y direction indicates the axial direction, the X direction indicates the width direction, and the Z direction is orthogonal to both the axial direction and the width direction.

In the push switch 10, the base portion 13 and the shaft 14 are arranged apart from each other in the axial direction, and a conical spring 16 is arranged coaxially with the central case 11 between the base portion 13 and the shaft 14. The conical spring 16 applies a reaction force to the shaft 14 that is pressed and moves along the axial direction and pushes it back.

A pair of first contact members 17 project axially from one end of the base 13 so as to sandwich the shaft 14. The base portion 13 has a holding portion 13a that holds the root of each of the first contact members 17, and each of the two conductors (not shown) attached to the push switch 10 inside and each of the first contact members 17. Connect each electrically. The first contact member 17 is made of an elastic conductive member such as copper and can warp in the Z direction. The first contact member 17 has a T-shape in a plan view, and both ends of a portion extended in the width direction at one end of the first contact member 17 form a sliding portion 17a, respectively. Further, in the first contact member 17, a contact portion 17b that curves and projects toward the shaft 14 is formed in a portion that is not expanded in the width direction between the portion that is expanded in the width direction and the holding portion 13a. NS. Therefore, the sliding portion 17a and the contact portion 17b of the portion expanded in the width direction are arranged apart from each other in the axial direction. Further, as described above, since each sliding portion 17a corresponds to both ends of the portion expanded in the width direction of the first contact member 17, the contact portion 17b formed in the portion not expanded in the width direction. The sliding portions 17a are arranged apart from each other in the width direction, and the contact portions 17b and the sliding portions 17a are not arranged in a straight line in the axial direction.

Further, since the portion expanded in the width direction is formed at one end of the first contact member 17, and the contact portion 17b is formed between the portion expanded in the width direction and the holding portion 13a, the holding portion of the base portion 13 is formed. The distance from the 13a to the sliding portion 17a of the first contact member 17 is larger than the distance from the holding portion 13a to the contact portion 17b.

In the pair of first contact members 17, when no external force is applied to any of the first contact members 17, the distance in the Z direction between the tips of the contact portions 17b is the thickness of the shaft 14 in the Z direction. Is set smaller than. Therefore, when the shaft 14 is sandwiched between the first contact members 17, each contact portion 17b comes into contact with the shaft 14.

A second U-shaped contact member 18 in a lateral view is arranged on the shaft 14 so as to sandwich the shaft 14 in between. The second contact member 18 is made of a conductive member, for example, copper whose surface is silver-plated, and a portion sandwiched between the shaft 14 of the second contact member 18 and each contact portion 17b constitutes a contact portion 18a. do. The portion of the shaft 14 facing each contact portion 17b forms a plane along the axial direction, and each contact portion 18a is arranged on this plane (hereinafter, referred to as “base surface”).

When each contact portion 17b comes into contact with each contact portion 18a, the second contact member 18 conducts each first contact member 17 with each other, and pulls each conducting wire connected to each first contact member 17. Conduct each other. In the present embodiment, a state in which each contact portion 17b contacts each contact portion 18a and each conducting wire conducts is referred to as an energization on state. Further, a state in which each contact portion 17b is separated from each contact portion 18a and the second contact member 18 does not conduct each first contact member 17 with each other, and as a result, the respective conducting wires are not conducted with each other is regarded as an energization off state. Refer to.

The shaft 14 is made of an insulating member, for example, a resin, and has a guide rib 14b (separation portion) that projects so as to be closer to the first contact member 17 than the contact portion 18a of the second contact member 18 in the Z direction. The guide rib 14b is arranged so as to correspond to each of the sliding portions 17a of the first contact member 17 in a plan view, and extends in the axial direction. Further, the guide rib 14b is arranged so as to be separated from the base portion 13 by the second contact member 18 in the axial direction, and has a flat surface (hereinafter, referred to as “top surface”) forming the top of the guide rib 14b in the Z direction. Further, the guide rib 14b has an inclined surface that connects the base surface of the shaft 14 and the top surface of the guide rib 14b and is inclined along the axial direction.

In the push switch 10, the distance in the Z direction between the sliding portions 17a when the contact portion 17b contacts the contact portion 18a is set to be smaller than the distance in the Z direction between the top surfaces of the guide ribs 14b. ..

Further, in the push switch 10, the shaft 14 is moved in the axial direction to engage the guide rib 14b with the sliding portion 17a of the first contact member 17, thereby switching between the energization on state and the energization off state. The shaft 14 moves in the axial direction when the protrusion 14a of the shaft 14 protruding from the front case 12 is mechanically pressed in the axial direction by a lever or the like.

4 and 5 are process diagrams for explaining switching between the energized on state and the energized off state in the push switch 10. FIG. 4 shows a case where the main part related to the switching of the energized state of the push switch 10 is viewed in a plan view (viewed along the Z direction), and FIG. 5 shows the main part related to the switching of the energized state of the push switch 10. The case of looking sideways (viewed along the X direction) is shown. In each drawing, for the sake of simplification, reference numerals relating to the first contact member 17, the second contact member 18, and the guide rib 14b are attached to only one of them.

In the push switch 10, when the protrusion 14a of the shaft 14 is not pressed in the axial direction (FIGS. 4A and 5A), as shown in the figure, the inclined surface of the guide rib 14b is the first contact member. Since it has not reached the sliding portion 17a of 17, each first contact member 17 sandwiches the shaft 14 in between without being displaced. Therefore, the contact portion 17b of the first contact member 17 remains in contact with the contact portion 18a of the second contact member 18, and the push switch 10 is turned on.

After that, the protrusion 14a of the shaft 14 is pressed in the axial direction, specifically, in the direction of the arrow in the drawing, and the shaft 14 moves. By the way, as described above, in the push switch 10, the distance in the Z direction between the sliding portions 17a when the contact portion 17b contacts the contact portion 18a is related to the Z direction between the top surfaces of the guide ribs 14b. Set smaller than the distance. Therefore, when the shaft 14 moves in the axial direction and the inclined surface of the guide rib 14b reaches the sliding portion 17a of the first contact member 17, the sliding portion 17a rides on the inclined surface, and a part of the guide rib 14b rides on the top surface. (FIG. 4 (B), FIG. 5 (B)). At this time, the guide rib 14b warps the first contact member 17 so that the contact portion 17b is separated from the shaft 14 in the Z direction. As a result, the contact portion 17b is separated from the contact portion 18a, and the push switch 10 is turned off.

Further, when the pressing of the protrusion 14a in the axial direction is continued, the shaft 14 further moves in the axial direction, and all the sliding portions 17a ride on the top surface (FIGS. 4 (C) and 5 (C)). At this time, the first contact member 17 is further warped away from the shaft 14 by the guide rib 14b, the amount of separation of the contact portion 17b from the contact portion 18a is maximized, and the contact portion 17b does not face the contact portion 18a. .. As a result, the contact between the contact portion 17b and the contact portion 18a is surely prevented, and the energization off state of the push switch 10 is ensured. In the push switch 10, the protrusion amount (height) of the guide rib 14b from the base surface is set so that the separation amount of the contact portion 17b from the contact portion 18a is at least 0.1 mm or more, preferably 0.2 mm or more. Will be done. Further, in order to secure the energization off state of the push switch 10, when all of the sliding portions 17a ride on the top surface, the contact portions 17b of the first contact member 17 move axially from the contact portion 18a. The distance is at least 0.1 mm or more (for example, the distance L shown in FIG. 4C is 0.1 mm or more).

By the way, when the sliding portion 17a rides on the inclined surface or the top surface of the guide rib 14b, the sliding portion 17a slides on the inclined surface or the top surface, so that the guide rib 14b of the shaft 14 or the first contact member 17 Friction powder may be generated from the sliding portion 17a, and the friction powder is urged by the shaft 14 and scatters in the moving direction of the shaft 14, that is, in the axial direction.

However, in the push switch 10, as described above, in the first contact member 17, the contact portion 17b and each sliding portion 17a are arranged apart from each other in the width direction, and the contact portion 17b and each sliding portion 17a are arranged. Not arranged in a straight line with respect to the axial direction. Therefore, even if the friction powder is scattered along the axial direction, it is difficult for the friction powder to enter between the contact portion 17b of the first contact member 17 and the contact portion 18a of the second contact member 18. As a result, the occurrence of contact failure can be suppressed.

Further, as described above, the amount of separation of the contact portion 17b from the contact portion 18a when all of the sliding portions 17a ride on the top surface of the guide rib 14b is at least 0.1 mm or more, but the guide rib 14b and the first Since the maximum size of the friction powder from the sliding portion 17a of the contact member 17 is about 0.1 mm, even if the friction powder enters between the sliding portion 17a and the contact portion 18a, the first contact member It is not sandwiched between the 17 and the second contact member 18. As a result, it is possible to prevent the friction powder from staying between the sliding portion 17a and the contact portion 18a, and thus it is possible to reliably suppress the occurrence of contact failure.

Further, in the push switch 10, since the sliding portion 17a and the contact portion 17b are arranged apart from each other in the first contact member 17 not only in the axial direction but also in the width direction, the sliding portion 17a and the contact portion 17b are arranged. The distance between the sliding portion 17a and the contact portion 17b is larger than when they are arranged in a straight line with respect to the axial direction. Therefore, the heat of the contact portion 17b is not easily transferred to the sliding portion 17a, the guide rib 14b that engages with the sliding portion 17a is prevented from being crushed due to thermal deformation, and the sliding portion 17a rides on the guide rib 14b. However, it is possible to prevent the contact portion 17b from remaining in contact with the contact portion 18a. As a result, the occurrence of insulation defects can be suppressed.

If the sliding portion 17a and the contact portion 17b are arranged in a straight line with respect to the axial direction, the contact with the sliding portion 17a is to prevent the heat of the contact portion 17b from being easily transferred to the sliding portion 17a. It is necessary to take a large distance between the portions 17b, and as a result, the size of the first contact member 17 is increased, which in turn leads to the increase in size of the push switch 10. However, as described above, in the push switch 10, in order to increase the distance between the sliding portion 17a and the contact portion 17b, the sliding portion 17a and the contact portion 17b are separated not only in the axial direction but also in the width direction. Deploy. This eliminates the need to increase the size of the first contact member 17, and prevents the push switch 10 from increasing in size.

Further, in the push switch 10, as described above, the distance from the holding portion 13a of the base portion 13 to the sliding portion 17a of the first contact member 17 is larger than the distance from the holding portion 13a to the contact portion 17b. That is, regarding the bending of the first contact member 17, the sliding portion 17a, which is the point of action, can be separated from the holding portion 13a, which is the fulcrum, and the sliding portion 17a is lifted by the guide rib 14b to shift to the energization off state. The bending stress of the first contact member 17 generated at the time of the operation can be relaxed, and the fatigue of the first contact member 17 can be suppressed.

Although the preferred embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications and changes can be made within the scope of the gist thereof.

For example, in the above-described embodiment, the first contact member 17 is fixed and does not move, and the second contact member 18 moves with respect to the first contact member 17 as the shaft 14 moves. The second contact member 18 may be fixed and not move, the base 13 may move, and the first contact member 17 may move with respect to the second contact member 18.

Further, for example, as shown in FIG. 6, the base surface and the top surface of the shaft 14 may be connected by an R surface instead of an inclined surface. Also in this case, when the sliding portion 17a rides on the top surface via the R surface, the guide rib 14b warps the first contact member 17 so that the contact portion 17b separates from the shaft 14, and as a result, the contact portion 17b Is separated from the contact portion 18a.

Further, for example, as shown in FIG. 7, the base surface and the top surface of the shaft 14 may not be connected by a surface to form a step. In this case, the sliding portion 17a is preformed so as to warp in the Z direction and the end portion of the sliding portion 17a to be higher than the top surface in the Z direction. As a result, when the shaft 14 moves toward the base portion 13, the end portion of the sliding portion 17a does not get caught in the step, the corner of the step abuts on the lower surface of the sliding portion 17a, and the step makes the sliding portion 17a. Push up in the Z direction. As a result, the contact portion 17b is separated from the contact portion 18a.

Further, in the above-described embodiment, by pressing the shaft 14 toward the base portion 13 in the axial direction, the contact portion 17b of the first contact member 17 is separated from the contact portion 18a of the second contact member 18. Although the push switch 10 has been moved to the power-off state, if the sliding portion 17a can be mounted on the top surface of the guide rib 14b, what form is the mechanism that realizes the relative movement of the shaft 14 and the base portion 13? It doesn't matter if there is.

Further, in the push switch 10, in the first contact member 17, the contact portion 17b and the sliding portion 17a are arranged apart not only in the width direction but also in the axial direction, but the contact portion 17b and the sliding portion 17a are at least separated. It does not have to be separated in the axial direction as long as it is separated in the width direction.

8 and 9 are process diagrams for explaining switching between an energized on state and an energized off state in a modified example of a push switch in which the contact portion 17b and the sliding portion 17a are not separated from each other in the axial direction. FIG. 8 shows a plan view of a main part related to switching the energized state of the modified example of the push switch, and FIG. 9 shows a side view of the main part related to switching the energized state of the modified example of the push switch. Is shown.

Even in the modified example of the push switch, when the protrusion 14a of the shaft 14 is not pressed in the axial direction (FIGS. 8A and 9A), the inclined surface of the guide rib 14b slides on the first contact member 17. Each of the first contact members 17 sandwiches the shaft 14 in between without reaching the portion 17a. Therefore, the contact portion 17b of the first contact member 17 remains in contact with the contact portion 18a of the second contact member 18, and the energization is turned on.

After that, when the protrusion 14a of the shaft 14 is pressed in the axial direction to move the shaft 14 and the inclined surface of the guide rib 14b reaches the sliding portion 17a of the first contact member 17, a part of the sliding portion 17a is inclined. Ride on the surface (Fig. 8 (B), Fig. 9 (B)). At this time, the contact portion 17b is lifted together with the sliding portion 17a in the Z direction, and the contact portion 17b is separated from the contact portion 18a. As a result, the energization is turned off.

Further, when the pressing of the protrusion 14a in the axial direction is continued, the shaft 14 further moves in the axial direction, and almost all of the sliding portions 17a ride on the top surface (FIGS. 8 (C) and 9 (C)). At this time, the amount of separation of the contact portion 17b that is lifted together with the sliding portion 17a from the contact portion 18a is maximized. As a result, the contact between the contact portion 17b and the contact portion 18a is surely prevented.

However, even in the modified example of the push switch, since the sliding portion 17a and the contact portion 17b are arranged apart from each other in the width direction, the sliding portion 17a and the contact portion 17b are not arranged in a straight line in the axial direction. As a result, even if the friction powder generated by the sliding of the sliding portion 17a and the contact portion 17b scatters along the axial direction, it is difficult for the friction powder to enter between the contact portion 17b and the contact portion 18a.

Further, the form of the second contact member 18 is not limited to the lateral U-shape, and may be, for example, a flat plate shape. In this case, as shown in FIG. 10, a pair of first contact members 17 are arranged side by side in the width direction, and each guide rib 14b is moved in the axial direction to warp each first contact member 17 in the same direction. Each contact portion 17b may be separated from the second contact member 18.

Further, in the above-described embodiment, the case where the present invention is applied to the push switch has been described, but in the present invention, each guide rib 14b and the first contact member 17 move relative to each other in a straight line. As shown in FIG. 11, it can be applied not only to a switch but also to a rotary switch in which each guide rib 14b and a first contact member 17 are arranged on the circumference and move relative to each other along an arc. can. That is, the present invention can be applied to any switch device in which the guide rib 14b and the first contact member 17 move relative to each other. Further, also in the rotary switch, as shown in FIG. 10, the second contact member 18 may be formed in a flat plate shape, and the pair of first contact members 17 may be arranged side by side in the width direction.

In the above-described embodiment, the height of the guide rib 14b from the base surface is set so that the distance between the contact portion 17b and the contact portion 18a is at least 0.1 mm or more, but the sliding portion 17a It is preferable to set the height of the guide rib 14b from the base surface with a margin in consideration of wear due to sliding with the guide rib 14b.
