Description
本発明は、ドーム状に形成された可動接点部材を備えるプッシュスイッチに関する。 The present invention relates to a push switch including a movable contact member formed in a dome shape.
近年、携帯機器の小型化や軽量化に伴い、使用するプッシュスイッチにもさらなる小型化が要求されている。小型のプッシュスイッチは、例えば、特許文献１に示す構成が知られている。 In recent years, as portable devices have become smaller and lighter, push switches to be used have been required to be further downsized. As a small push switch, for example, a configuration disclosed in Patent Document 1 is known.
図１１は、従来のプッシュスイッチ１００の構成部品を示す分解斜視図である。図１２は、プッシュスイッチ１００の側面側の外観および内部構造を示す図であり、図１２（ａ）はプッシュスイッチ１００の側面図であり、図１２（ｂ）は断面図である。プッシュスイッチ１００は、図１１に示すように、複数の固定接点部材１１４を有するケース１１１と、ケース１１１に配され、押圧操作に応じて複数の固定接点部材１１４に離接する可動接点部材１１２と、可動接点部材１１２を固定接点部材１１４と離説可能な状態でケース１１１に保持するシート部材１１３とを備えている。 FIG. 11 is an exploded perspective view showing components of the conventional push switch 100. 12A and 12B are diagrams showing the appearance and internal structure of the push switch 100 on the side surface side, FIG. 12A is a side view of the push switch 100, and FIG. 12B is a sectional view. As shown in FIG. 11, the push switch 100 includes a case 111 having a plurality of fixed contact members 114, a movable contact member 112 arranged in the case 111, and separated from and brought into contact with the plurality of fixed contact members 114 according to a pressing operation. The movable contact member 112 includes a fixed contact member 114 and a sheet member 113 that holds the movable contact member 112 in a separable state in the case 111.
可動接点部材１１２は金属板からなり、図１１および図１２（ｂ）に示すように、略円形のドーム形状に形成され、Ｚ１方向に膨出している。膨出した部分の中央部が可動接点部１１２ａとなっている。可動接点部材１１２は、可動接点部１１２ａがＺ１方向から押圧されるとＺ２方向へ撓んだ後に反転し、押圧を解除すると押圧前の形状に戻る。可動接点部材１１２は、図１１および図１２（ｂ）に示すように、ケース１１１の配置部１１１ｂに配置される。可動接点部１１２ａがケース１１１に設けられた第１固定接点部１１４ａに対応するように配置され、Ｚ１方向から操作されると第１固定接点部１１４ａと電気的に接続するようになる。また、外縁部が第２固定接点部１１４ｂと当接するように配置されて電気的に接続される。シート部材１１３は、光に対しての透過性があり可撓性を有した合成樹脂材料からなり、シート状に形成されている。図１１に示すように、シート部材１１３の外形は略四角形に形成されている。押し子１１６は、合成樹脂材料からなり、略円筒形状に形成されて、および図１２（ｂ）に示すように、可動接点部材１１２とシート部材１１３との間に配置されている。押し子１１６は、シート部材１１３にレーザ溶着により固着されており、シート部材１１３側が曲面形状となっている。そして、可動接点部材１１２のドーム形状の頂点部分に対応するように配置されている。 The movable contact member 112 is made of a metal plate, has a substantially circular dome shape, and bulges in the Z1 direction, as shown in FIGS. 11 and 12B. The central portion of the bulged portion serves as the movable contact portion 112a. When the movable contact portion 112a is pressed from the Z1 direction, the movable contact member 112 bends in the Z2 direction and then reverses. When the pressing is released, the movable contact member 112 returns to the shape before the pressing. The movable contact member 112 is arranged in the arrangement portion 111b of the case 111, as shown in FIGS. 11 and 12B. The movable contact portion 112a is arranged so as to correspond to the first fixed contact portion 114a provided in the case 111, and when operated in the Z1 direction, the movable contact portion 112a is electrically connected to the first fixed contact portion 114a. Further, the outer edge portion is arranged so as to be in contact with the second fixed contact portion 114b and electrically connected. The sheet member 113 is made of a synthetic resin material that is transparent to light and has flexibility, and is formed in a sheet shape. As shown in FIG. 11, the outer shape of the sheet member 113 is formed in a substantially square shape. The pusher 116 is made of a synthetic resin material, has a substantially cylindrical shape, and is arranged between the movable contact member 112 and the sheet member 113 as shown in FIG. 12B. The pusher 116 is fixed to the sheet member 113 by laser welding, and the sheet member 113 side has a curved shape. The movable contact member 112 is arranged so as to correspond to the dome-shaped apex portion.
これにより、シート部材１１３と押し子１１６とを溶着することで、可動接点部材２１２と押し子１１６との接触位置が安定する。 As a result, by welding the sheet member 113 and the pusher 116, the contact position between the movable contact member 212 and the pusher 116 is stabilized.
しかしながら、プッシュスイッチの小型化に伴って、可動接点部材１１２とシート部材１１３との間に配置される押し子１１６の径を小さくしないと、プッシュスイッチの操作感触が悪くなるという課題があった。一方、押し子１１６の径を小さくすると、横から力を受けた場合に、押し子１１６とシート部材１１３との接合面が剥がれやすくなってしまうという課題があった。このため、押し子１１６の接触位置がずれて、可動接点部材１１２を適切に押圧することができなくなるという懸念があった。 However, with the downsizing of the push switch, there is a problem that the feel of operation of the push switch deteriorates unless the diameter of the pusher 116 arranged between the movable contact member 112 and the sheet member 113 is reduced. On the other hand, when the diameter of the pusher 116 is reduced, there is a problem that the joint surface between the pusher 116 and the sheet member 113 is easily peeled off when a force is applied from the side. Therefore, there is a concern that the contact position of the pusher 116 may be displaced and the movable contact member 112 may not be appropriately pressed.
本発明は、上述した課題を解決するもので、横押しされた場合でも接合面が剥がれにくく、操作感触のよいプッシュスイッチを提供することを目的とする。 The present invention solves the above-described problems, and an object of the present invention is to provide a push switch that is difficult to peel off the joint surface even when laterally pushed and has a good operation feeling.
本発明は、ドーム状に形成された可動接点部材と、前記可動接点部材を収容する収容部を有するケースと、前記収容部に配設され前記可動接点部材に接触可能な固定接点部材と、前記収容部を覆うように配置されたシート部材と、前記シート部材と前記可動接点部材との間に配置された押し子部材と、を備えたプッシュスイッチにおいて、前記押し子部材は、一端側で前記シート部材に接合された接合面と、他端側で前記可動接点部材に当接する当接面と、を有し、前記接合面が前記当接面に比べて大きい面積となるように設けられていることを特徴とする。 The present invention relates to a movable contact member formed in a dome shape, a case having an accommodating portion for accommodating the movable contact member, a fixed contact member arranged in the accommodating portion and capable of contacting the movable contact member, In a push switch provided with a sheet member arranged so as to cover the accommodating portion, and a pusher member arranged between the sheet member and the movable contact member, the pusher member is provided with one end side of the push member. A joint surface joined to the sheet member, and a contact surface contacting the movable contact member on the other end side, and the joint surface is provided so as to have a larger area than the contact surface. It is characterized by being
この構成によれば、小型化した場合にもシート部材との接合面積が大きくなるので、横押しされた場合でも接合面が剥がれにくくすることができる。したがって、横押しされた場合でも接合面が剥がれにくく、操作感触のよいプッシュスイッチを提供することができる。 According to this configuration, the joint area with the sheet member is increased even when the size is reduced, so that the joint surface can be made difficult to peel off even when laterally pressed. Therefore, it is possible to provide a push switch that is hard to peel off the joint surface even when it is laterally pushed and has a good operation feeling.
また、本発明のプッシュスイッチにおいて、前記押し子部材は、前記当接面を底面とする本体部と、前記一端側で前記本体部の側面から外方に延在する鍔部と、を備え、前記接合面は、前記本体部および前記鍔部が前記一端側で前記シート部材に接合されることによって形成されることを特徴とする。 In the push switch of the present invention, the pusher member includes a main body portion having the contact surface as a bottom surface, and a flange portion that extends outward from a side surface of the main body portion on the one end side, The joining surface is formed by joining the body portion and the collar portion to the sheet member at the one end side.
この構成によれば、押し子部材は、一端側で本体部の側面から外方に延在する鍔部も接合されることによって接合面が形成されているので、本体部の底面である当接面が大きくなってしまうことがなく、可動接点部材の反転動作を安定して行うことができる。 According to this structure, since the pusher member has the joining surface formed by joining the brim portion that extends outward from the side surface of the main body portion at one end side, the pressing member is the bottom surface of the main body portion. The surface does not become large, and the reversing operation of the movable contact member can be stably performed.
また、本発明のプッシュスイッチにおいて、前記鍔部の厚さが前記シート部材の厚さの２倍以下であることを特徴とする。 Further, in the push switch of the present invention, the thickness of the collar portion is not more than twice the thickness of the sheet member.
この構成によれば、押し子部材の鍔部の厚さがシート部材の厚さの２倍以下であれば、押圧操作によるシート部材の変形に鍔部が追随できるので、可動接点部材の反転動作を確実に行うことができる。 According to this structure, if the thickness of the flange portion of the pusher member is equal to or less than twice the thickness of the sheet member, the flange portion can follow the deformation of the sheet member due to the pressing operation. Can be reliably performed.
また、本発明のプッシュスイッチにおいて、前記押し子部材が暗色系の合成樹脂からなり、前記シート部材が透光性の合成樹脂からなることを特徴とする。 Further, in the push switch of the present invention, the pusher member is made of a dark-colored synthetic resin, and the sheet member is made of a translucent synthetic resin.
この構成によれば、透光性の合成樹脂からなるシート部材の上から暗色系の合成樹脂からなる押し子部材が視認可能であるため、表面が平坦な状態であっても押し子部材の配置が確認できる。 According to this configuration, since the pusher member made of the synthetic resin of dark color can be visually recognized from the top of the sheet member made of the translucent synthetic resin, even if the surface is flat, the pusher member can be arranged. Can be confirmed.
また、本発明のプッシュスイッチにおいて、前記押し子部材は、前記一端側が前記シート部材側に凸となる曲面形状であり、前記シート部材は前記接合面から外方に亘って曲面形状となっていることを特徴とする。 Further, in the push switch of the present invention, the pusher member has a curved surface shape in which the one end side is convex toward the sheet member side, and the sheet member has a curved surface shape extending outward from the joint surface. It is characterized by
この構成によれば、操作される部分が曲面形状となっていることで、操作位置を安定させることができる。また押圧方向をシート部材の追随しやすい方向にできるため、操作感触がよい。 According to this configuration, since the operated portion has a curved surface shape, the operation position can be stabilized. In addition, since the pressing direction can be made to follow the sheet member easily, the operation feeling is good.
本発明によれば、押し子部材は、一端側でシート部材に接合された接合面と、他端側で可動接点部材に当接する当接面とを有し、接合面が当接面に比べて大きい面積となるように設けられている。したがって、横押しされた場合でも接合面が剥がれにくく、操作感触のよいプッシュスイッチを提供することができる。 According to the present invention, the pusher member has a joining surface joined to the sheet member at one end side and an abutting surface abutting against the movable contact member at the other end side, and the joining surface is compared to the abutting surface. It has a large area. Therefore, it is possible to provide a push switch that is hard to peel off the joint surface even when it is laterally pushed and has a good operation feeling.

本発明の第１実施形態のプッシュスイッチ１は、図１に示すように、略直方体の外観を備え、電子機器等の回路基板に実装される。プッシュスイッチ１は、図２に示すように、収容部１１ｂを有するケース１１と、収容部１１ｂに配設された固定接点部材１４と、収容部１１ｂを覆うように配置されたシート部材１３と、収容部１１ｂに配置された可動接点部材１２と押し子部材１６とを備える。 As shown in FIG. 1, the push switch 1 according to the first embodiment of the present invention has a substantially rectangular parallelepiped appearance and is mounted on a circuit board of an electronic device or the like. As shown in FIG. 2, the push switch 1 includes a case 11 having a housing portion 11b, a fixed contact member 14 arranged in the housing portion 11b, and a sheet member 13 arranged so as to cover the housing portion 11b. The movable contact member 12 and the pusher member 16 arranged in the housing portion 11b are provided.
ケース１１は、絶縁材料の合成樹脂を用いて射出成形されており、図２に示すように、一方が開口した収容部１１ｂを有する箱形形状に形成されている。ケース１１に用いられている合成樹脂は、光が透過しにくい黒色などの暗色系の合成樹脂からなる。このケース１１には、図２および図３に示すように、固定接点部材１４が埋設されている。 The case 11 is injection-molded by using a synthetic resin of an insulating material, and as shown in FIG. 2, is formed in a box shape having a housing portion 11b having one opening. The synthetic resin used for the case 11 is made of a dark-colored synthetic resin such as black, which is difficult to transmit light. As shown in FIGS. 2 and 3, a fixed contact member 14 is embedded in the case 11.
固定接点部材１４は、導電性の金属板を機械加工して作製されており、図２に示すように、ケース１１の収容部１１ｂから第１固定電極部１４ａおよび第２固定電極部１４ｂが露出し、側壁１１ｃから第１端子部１４ｃおよび第２端子部１４ｄが露出している。収容部１１ｂの中央部に配設された第１固定電極部１４ａは、第１端子部１４ｃに接続されている。第１固定電極部１４ａから見て収容部１１ｂのＸ１−Ｘ２方向の両側に配設された第２固定電極部１４ｂは、第２端子部１４ｄに接続されている。なお、第１固定電極部１４ａと第２固定電極部１４ｂとは接続されていない。ケース１１が絶縁材料で形成されているので、第１固定電極部１４ａと第２固定電極部１４ｂとは電気的に絶縁されており、同様に第１端子部１４ｃと第２端子部１４ｄとは絶縁されている。ケース１１と固定接点部材１４とは、例えばインサート成形によって一体化される。 The fixed contact member 14 is manufactured by machining a conductive metal plate, and as shown in FIG. 2, the first fixed electrode portion 14a and the second fixed electrode portion 14b are exposed from the housing portion 11b of the case 11. Then, the first terminal portion 14c and the second terminal portion 14d are exposed from the side wall 11c. The 1st fixed electrode part 14a arrange | positioned at the center part of the accommodating part 11b is connected to the 1st terminal part 14c. The second fixed electrode portions 14b arranged on both sides in the X1-X2 direction of the housing portion 11b when viewed from the first fixed electrode portion 14a are connected to the second terminal portion 14d. The first fixed electrode portion 14a and the second fixed electrode portion 14b are not connected. Since the case 11 is formed of an insulating material, the first fixed electrode portion 14a and the second fixed electrode portion 14b are electrically insulated from each other, and the first terminal portion 14c and the second terminal portion 14d are similarly separated from each other. It is insulated. The case 11 and the fixed contact member 14 are integrated by, for example, insert molding.
可動接点部材１２は、導電性の金属板を機械加工して作製されており、図２に示すように、頂部１２ａがＺ１側に突出するドーム状に形成されている（図５参照）。可動接点部材１２は、収容部１１ｂに収容されたときに、第２固定電極部１４ｂと接触するように設けられている。この状態では、可動接点部材１２はドーム状に湾曲しているので、第１固定電極部１４ａと接触しない。 The movable contact member 12 is manufactured by machining a conductive metal plate, and as shown in FIG. 2, the top 12a is formed in a dome shape protruding toward the Z1 side (see FIG. 5). The movable contact member 12 is provided so as to come into contact with the second fixed electrode portion 14b when housed in the housing portion 11b. In this state, since the movable contact member 12 is curved in a dome shape, it does not come into contact with the first fixed electrode portion 14a.
シート部材１３は、絶縁材料の合成樹脂の薄板を用いて、平面視で略長方形に加工されている。シート部材１３に用いられている合成樹脂は、乳白色などの透光性の合成樹脂からなる。シート部材１３には、中央部でＺ１側に膨らんだ膨出中央部１３ａが形成されている。また、シート部材１３は、膨出中央部１３ａから外方に亘って曲面形状となっている膨出周辺部１３ｂが形成されて、膨出周辺部１３ｂは外縁領域の平坦部１３ｃより僅かに膨らんでいる。収容部１１ｂを覆うように配置されるシート部材１３をケース１１に貼着するため、シート部材１３の４隅には、図３に示すように、粘着材１３ｄが貼付されている。なお、シート部材１３を剥がれにくくするため、ケース１１に溶着させることが好ましい。本実施形態のプッシュスイッチ１では、シート部材１３が透光性の合成樹脂からなり、ケース１１が暗色系の合成樹脂からなるので、シート部材１３を通してレーザ光を照射することでレーザ溶着によって溶着させることが可能である。 The sheet member 13 is formed into a substantially rectangular shape in a plan view using a thin plate made of a synthetic resin that is an insulating material. The synthetic resin used for the sheet member 13 is made of translucent synthetic resin such as milky white. The sheet member 13 is formed with a bulging central portion 13a which bulges toward the Z1 side at the central portion. Further, the sheet member 13 is formed with a bulging peripheral portion 13b having a curved shape extending outward from the bulging central portion 13a, and the bulging peripheral portion 13b swells slightly from the flat portion 13c in the outer edge region. I'm out. In order to attach the sheet member 13 arranged so as to cover the accommodation portion 11b to the case 11, as shown in FIG. 3, adhesive materials 13d are attached to the four corners of the sheet member 13. It is preferable to weld the sheet member 13 to the case 11 in order to prevent the sheet member 13 from coming off easily. In the push switch 1 according to the present embodiment, the sheet member 13 is made of a translucent synthetic resin and the case 11 is made of a dark-colored synthetic resin. Therefore, when the sheet member 13 is irradiated with laser light, the sheet member 13 is welded by laser welding. It is possible.
押し子部材１６は、絶縁材料の合成樹脂を用いて形成されている。押し子部材１６に用いられている合成樹脂は、光が透過しにくい黒色などの暗色系の合成樹脂からなる。押し子部材１６は、図２、図３および図５に示すように、円柱形状の本体部１６ｃと、一端側で本体部１６ｃの側面から外方に延在する鍔部１６ｄと、を備えている。押し子部材１６は、一端側がシート部材１３の膨出中央部１３ａの形状に倣って中央部分がシート部材１３側（Ｚ１側）に凸となる曲面形状に形成されている。そして、本体部１６ｃおよび鍔部１６ｄが一端側でシート部材１３の膨出中央部１３ａに接合されている。この接合面１６ａは、図６にクロスハッチで示すように、鍔部１６ｄの外縁まで拡がっている。なお、図６では接合面１６ａを示すクロスハッチが分かりにくくならないように、断面を示すハッチングを省いている。一方、押し子部材１６の他端側である本体部１６ｃの底面は、可動接点部材１２の頂部１２ａに当接する当接面１６ｂになっている。 The pusher member 16 is formed using a synthetic resin of an insulating material. The synthetic resin used for the pusher member 16 is made of a dark-colored synthetic resin such as black, which is less likely to transmit light. As shown in FIGS. 2, 3, and 5, the pusher member 16 includes a columnar main body portion 16c and a flange portion 16d that extends outward from the side surface of the main body portion 16c at one end side. There is. The pusher member 16 is formed in a curved shape in which one end side follows the shape of the bulging central portion 13a of the sheet member 13 and the central portion is convex toward the sheet member 13 side (Z1 side). The main body portion 16c and the flange portion 16d are joined to the bulging central portion 13a of the sheet member 13 at one end side. The joint surface 16a extends to the outer edge of the collar portion 16d as shown by a cross hatch in FIG. In FIG. 6, hatching showing a cross section is omitted so that the cross hatch showing the joint surface 16a is not easily understood. On the other hand, the bottom surface of the main body portion 16c, which is the other end side of the pusher member 16, is a contact surface 16b that contacts the top portion 12a of the movable contact member 12.
本実施形態では、図６に示すように、鍔部１６ｄの厚さＴ１６がシート部材１３の厚さＴ１３の２倍以下である。押し子部材１６の本体部１６ｃは弾性変形しにくい形状となっているが、鍔部１６ｄは厚さＴ１６が薄いため比較的容易に弾性変形可能である。押し子部材１６の他端側では、図５に示すように、可動接点部材１２の頂部１２ａに当接する当接面１６ｂとなっている。 In this embodiment, as shown in FIG. 6, the thickness T16 of the collar portion 16d is not more than twice the thickness T13 of the sheet member 13. The body portion 16c of the pusher member 16 has a shape that is not easily elastically deformed, but the collar portion 16d is relatively easily elastically deformable because the thickness T16 is thin. On the other end side of the pusher member 16, as shown in FIG. 5, an abutting surface 16b that abuts on the top 12a of the movable contact member 12 is formed.
押し子部材１６の一端側をシート部材１３に接合する方法は、接着材を用いた接着でもよいが、レーザ溶着や超音波溶着によって合成樹脂材同士を溶着して接合することが好ましい。このとき、本体部１６ｃと鍔部１６ｄとが均一に溶着されるように、均一に加圧して合成樹脂材同士を密着させておくことが好ましい。このためには、型（金型等）に押し子部材１６をセッティングしてシート部材１３を均一な圧力で押し当てるようにして製造することが好適である。レーザ溶着を適用する場合には、シート部材１３を透光性の冶具で押し子部材１６に押し付けるようにして加圧しながら、透光性の冶具を通してレーザ光を照射すればよい。 A method of joining one end side of the pusher member 16 to the sheet member 13 may be adhesion using an adhesive material, but it is preferable to weld the synthetic resin materials to each other by laser welding or ultrasonic welding. At this time, it is preferable that the synthetic resin materials are brought into close contact with each other by uniformly pressurizing so that the main body portion 16c and the flange portion 16d are evenly welded. For this purpose, it is preferable that the pusher member 16 is set in a mold (mold or the like) and the sheet member 13 is pressed with a uniform pressure for manufacturing. When laser welding is applied, the sheet member 13 may be irradiated with a laser beam through a transparent jig while pressing the sheet member 13 against the pusher member 16 with the transparent jig.
なお、シート部材１３と押し子部材１６とを接合してから、加熱しながら加圧することによって膨出中央部１３ａを形成するようにしてもよい。この場合には、接合工程において接合される合成樹脂同士の面が平面でよいので、接合工程が容易になって均一に接合しやすい効果を有する。また、接合してから曲面形状に加圧することで、接合が不十分だった場合に接合状態が改善される効果も奏する。 Alternatively, the bulging central portion 13a may be formed by joining the sheet member 13 and the pusher member 16 and then applying pressure while heating. In this case, since the surfaces of the synthetic resins to be joined in the joining step may be flat surfaces, the joining step is facilitated, and there is an effect that uniform joining is facilitated. In addition, by applying pressure to a curved shape after joining, there is an effect that the joining state is improved when joining is insufficient.
次に、本実施形態のプッシュスイッチ１の動作について説明する。 Next, the operation of the push switch 1 of this embodiment will be described.
本実施形態のプッシュスイッチ１は、シート部材１３の膨出中央部１３ａをＺ２側に向かって押圧すると、可動接点部材１２が弾性変形して撓み、さらに、図７に示すように頂部１２ａがＺ２側へ反転する。可動接点部材１２が反転したときには、第１固定電極部１４ａと頂部１２ａが接触して、第１端子部１４ｃと第２端子部１４ｄとが電気的に導通した状態になる。 In the push switch 1 of this embodiment, when the bulging central portion 13a of the sheet member 13 is pressed toward the Z2 side, the movable contact member 12 is elastically deformed and bent, and further, as shown in FIG. 7, the top portion 12a is Z2. Flip to side. When the movable contact member 12 is reversed, the first fixed electrode portion 14a and the top portion 12a come into contact with each other, and the first terminal portion 14c and the second terminal portion 14d are electrically connected.
なお、このときにシート部材１３の膨出中央部１３ａは膨らみが小さくなるように弾性変形し、これに倣って押し子部材１６の鍔部１６ｄも追随して弾性変形する。また、シート部材１３は面方向に圧縮されるので、膨出周辺部１３ｂおよび平坦部１３ｃは、Ｚ１側またはＺ２側に僅かに波打つように弾性変形して圧縮応力を吸収する。 At this time, the bulging central portion 13a of the sheet member 13 is elastically deformed so that the bulge is small, and the brim portion 16d of the pusher member 16 is also elastically deformed following this. Further, since the sheet member 13 is compressed in the surface direction, the bulging peripheral portion 13b and the flat portion 13c elastically deform so as to be slightly wavy on the Z1 side or the Z2 side to absorb the compressive stress.
押し子部材１６の当接面１６ｂは、可動接点部材１２の頂部１２ａを押圧するように配設されているので、可動接点部材１２が反転する動作を適切に行わせることができ、操作感触がよいとされる。もし、可動接点部材１２の頂部１２ａから位置ずれした状態で押し子部材１６が配置されていると、可動接点部材１２の反転動作が不安定になったり、操作感触が悪くなったりすることが知られている。 Since the contact surface 16b of the pusher member 16 is arranged so as to press the top portion 12a of the movable contact member 12, it is possible to appropriately perform the operation of reversing the movable contact member 12, and the operation feeling is improved. It is considered good. It is known that if the pusher member 16 is arranged in a state of being displaced from the top portion 12a of the movable contact member 12, the reversing operation of the movable contact member 12 becomes unstable and the operation feeling becomes bad. Has been.
なお、押し子部材１６の本体部１６ｃを鍔部１６ｄの外径まで拡げてしまうと、当接面１６ｂが可動接点部材１２の大きさに比べて大きくなり過ぎてしまい、頂部１２ａを適切に押圧できなくなってしまう。この場合には、操作感触が悪くなることが確認された。したがって、当接面１６ｂを大きくすることなく、一端側で本体部１６ｄの側面から外方に延在する鍔部１６ｄを設けることによって接合面１６ａ（図６参照）の接合面積を大きくすることが好ましい。 If the main body portion 16c of the pusher member 16 is expanded to the outer diameter of the flange portion 16d, the contact surface 16b becomes too large compared to the size of the movable contact member 12, and the top portion 12a is appropriately pressed. I can not do it. In this case, it was confirmed that the feeling of operation became poor. Therefore, the joint area of the joint surface 16a (see FIG. 6) can be increased by providing the flange portion 16d extending outward from the side surface of the main body portion 16d at one end side without enlarging the contact surface 16b. preferable.
本実施形態のプッシュスイッチ１は、押し子部材１６の本体部１６ｃおよび鍔部１６ｄが一端側でシート部材１３に接合されているので、接合面１６ａが当接面１６ｂに比べて大きい面積となるように設けられている。図３に示すように本体部１６ｃの側面から外方に延在する鍔部１６ｄは、接合面１６ａの接合面積をほぼ２倍に増大させている。このため、接合面積に比例して、シート部材１３との接合強度を高めることができる。これにより、小型化した場合にもシート部材１３との接合面積が大きくなるので、横押しされた場合でも接合面１６ａが剥がれにくい。したがって、横押しされた場合でも接合面１６ａが剥がれにくくなる。 In the push switch 1 of the present embodiment, since the main body portion 16c and the flange portion 16d of the pusher member 16 are joined to the sheet member 13 at one end side, the joint surface 16a has a larger area than the contact surface 16b. Is provided. As shown in FIG. 3, the collar portion 16d extending outward from the side surface of the main body portion 16c doubles the joint area of the joint surface 16a. Therefore, the joint strength with the sheet member 13 can be increased in proportion to the joint area. As a result, the joint area with the sheet member 13 is increased even when the size is reduced, so that the joint surface 16a is less likely to peel off even when laterally pressed. Therefore, the joining surface 16a is less likely to peel off even when laterally pushed.
以下、本実施形態としたことによる効果について説明する。 The effects of the present embodiment will be described below.
本実施形態のプッシュスイッチ１は、ドーム状に形成された可動接点部材１２と、収容部１１ｂを有するケース１１と、可動接点部材１２に接触可能な固定接点部材１４と、収容部１１ｂを覆うように配置されたシート部材１３と、シート部材１３と可動接点部材１２との間に配置された押し子部材１６と、を備える。そして、押し子部材１６は、一端側でシート部材１３に接合された接合面１６ａと、他端側で可動接点部材１２に当接する当接面１６ｂと、を有し、接合面１６ａが当接面１６ｂに比べて大きい面積となるように設けられている。 The push switch 1 of the present embodiment covers the movable contact member 12 formed in a dome shape, the case 11 having the accommodating portion 11b, the fixed contact member 14 contactable with the movable contact member 12, and the accommodating portion 11b. And a pusher member 16 disposed between the sheet member 13 and the movable contact member 12. The pusher member 16 has a joining surface 16a joined to the sheet member 13 on one end side and an abutting surface 16b that abuts on the movable contact member 12 on the other end side. The area is larger than that of the surface 16b.
この構成によれば、小型化した場合にもシート部材１３と押し子部材１６との接合面積が大きくなるので、横押しされた場合でも接合面１６ａが剥がれにくい。したがって、横押しされた場合でも接合面１６ａが剥がれにくく、操作感触のよいプッシュスイッチ１を提供することができる。 According to this configuration, the joint area between the sheet member 13 and the pusher member 16 becomes large even when the size is reduced, so that the joint surface 16a is unlikely to peel off even when laterally pushed. Therefore, it is possible to provide the push switch 1 having a good feeling of operation, because the joint surface 16a is not easily peeled off even when laterally pushed.
また、本実施形態のプッシュスイッチ１において、押し子部材１６は、当接面１６ｂを底面とする本体部１６ｃと、一端側で本体部１６ｃの側面から外方に延在する鍔部１６ｄと、を備える。そして、接合面１６ａは、本体部１６ｃおよび鍔部１６ｄが一端側でシート部材１３に接合されることによって形成される。 Further, in the push switch 1 of the present embodiment, the pusher member 16 includes a main body portion 16c having a contact surface 16b as a bottom surface, and a flange portion 16d extending outward from a side surface of the main body portion 16c at one end side. Equipped with. The joining surface 16a is formed by joining the body portion 16c and the flange portion 16d to the sheet member 13 at one end side.
この構成によれば、一端側で本体部１６ｃの側面から外方に延在する鍔部１６ｄも接合されることによって接合面１６ａが形成されているので、本体部１６ｃの底面である当接面１６ｂが大きくなってしまうことがなく、可動接点部材１２の反転動作を安定して行うことができる。 According to this configuration, the joint surface 16a is formed by joining the flange portion 16d extending outward from the side surface of the main body portion 16c at one end side, so that the contact surface that is the bottom surface of the main body portion 16c is formed. 16b does not become large, and the reversing operation of the movable contact member 12 can be stably performed.
また、本実施形態のプッシュスイッチ１において、鍔部１６ｄの厚さＴ１６がシート部材１３の厚さＴ１３の２倍以下であることが好ましい。 In addition, in the push switch 1 of the present embodiment, it is preferable that the thickness T16 of the flange portion 16d be equal to or less than twice the thickness T13 of the sheet member 13.
鍔部１６ｄの厚さＴ１６がシート部材１３の厚さＴ１３の２倍以下であれば、押圧操作によるシート部材１３の変形に鍔部１６ｄが追随できるので、可動接点部材１２の反転動作を確実に行うことができる。 If the thickness T16 of the collar portion 16d is equal to or less than twice the thickness T13 of the sheet member 13, the collar portion 16d can follow the deformation of the sheet member 13 due to the pressing operation, so that the reversing operation of the movable contact member 12 can be reliably performed. It can be carried out.
また、本実施形態のプッシュスイッチ１において、押し子部材１６は、一端側がシート部材１３側に凸となる曲面形状であり、シート部材１３は接合面１６ａから外方に亘って曲面形状となっている。 Further, in the push switch 1 of the present embodiment, the pusher member 16 has a curved surface shape whose one end side is convex toward the sheet member 13 side, and the sheet member 13 has a curved surface shape extending outward from the joint surface 16a. There is.
この構成によれば、操作される部分が曲面形状となっていることで、操作位置を安定させることができる。また押圧方向をシート部材１３の追随しやすい方向にできるため、操作感触がよい。 According to this configuration, since the operated portion has a curved surface shape, the operation position can be stabilized. Further, since the pressing direction can be set to the direction in which the sheet member 13 can easily follow, the operation feeling is good.
［第２実施形態］
本発明の第１実施形態のプッシュスイッチ１は、膨出中央部１３ａが形成されているシート部材１３を用いているが、本発明の第２実施形態のプッシュスイッチ２は平坦な構成であり、この場合でも本発明を実施することが可能である。
[Second Embodiment]
The push switch 1 according to the first embodiment of the present invention uses the sheet member 13 in which the bulged central portion 13a is formed, but the push switch 2 according to the second embodiment of the present invention has a flat configuration. Even in this case, the present invention can be implemented.
本発明の第２実施形態のプッシュスイッチ２について以下に説明する。図８は、本発明の第２実施形態のプッシュスイッチ２を示す外形図であり、図８（ａ）は平面図であり、図８（ｂ）は正面図である。図９は、図８（ａ）のＩＸ−ＩＸ線で切断した断面図である。図１０は、図９の断面において押し子部材２６の一端側の接合面２６ａおよび他端側の当接面２６ｂを説明する模式図である。なお、図１０では断面を示すハッチングを省いている。 The push switch 2 according to the second embodiment of the present invention will be described below. 8A and 8B are external views showing the push switch 2 according to the second embodiment of the present invention, FIG. 8A is a plan view, and FIG. 8B is a front view. FIG. 9 is a sectional view taken along line IX-IX in FIG. FIG. 10 is a schematic diagram illustrating the joining surface 26a on one end side and the contact surface 26b on the other end side of the pusher member 26 in the cross section of FIG. In FIG. 10, hatching showing the cross section is omitted.
第２実施形態のプッシュスイッチ２は、図８〜図１０に示すように、収容部２１ｂを有するケース２１と、収容部２１ｂに配設された固定接点部材２４と、収容部２１ｂを覆うように配置されたシート部材２３と、収容部２１ｂに配置された可動接点部材２２と押し子部材２６とを備える。固定接点部材２４は、ケース２１の収容部２１ｂから第１固定電極部２４ａおよび第２固定電極部２４ｂが露出し、側壁２１ｃから第１端子部２４ｃおよび第２端子部２４ｄが露出している。可動接点部材２２は、可動接点部材１２と同じものである。押し子部材２６は、円柱形状の本体部２６ｃと、一端側で本体部２６ｃの側面から外方に延在する鍔部２６ｄと、を備えている。押し子部材２６の他端側である本体部２６ｃの底面は、可動接点部材２２の頂部２２ａに当接する当接面２６ｂになっている。なお、プッシュスイッチ２に用いられている各部材の材質はプッシュスイッチ１の各部材と同じであり、詳細な説明を省略する。 As shown in FIGS. 8 to 10, the push switch 2 according to the second embodiment covers the case 21 having the housing portion 21b, the fixed contact member 24 arranged in the housing portion 21b, and the housing portion 21b. The sheet member 23 arranged, the movable contact member 22 and the pusher member 26 arranged in the housing portion 21b are provided. In the fixed contact member 24, the first fixed electrode portion 24a and the second fixed electrode portion 24b are exposed from the housing portion 21b of the case 21, and the first terminal portion 24c and the second terminal portion 24d are exposed from the side wall 21c. The movable contact member 22 is the same as the movable contact member 12. The pusher member 26 includes a columnar main body portion 26c and a flange portion 26d that extends outward from the side surface of the main body portion 26c at one end side. The bottom surface of the main body portion 26c, which is the other end side of the pusher member 26, is a contact surface 26b that contacts the top portion 22a of the movable contact member 22. The material of each member used in the push switch 2 is the same as that of each member of the push switch 1, and detailed description thereof will be omitted.
第２実施形態のプッシュスイッチ２は、シート部材２３が平坦であり、その中央部に押し子部材２６の一端側の接合面２６ａが接合されている。押し子部材２６は、当接面２６ｂを底面とする本体部２６ｃと、一端側で本体部２６ｃの側面から外方に延在する鍔部２６ｄと、を備える。そして、接合面２６ａは、本体部２６ｃおよび鍔部２６ｄが一端側でシート部材２３に接合されることによって形成される。この接合面２６ａは、図１０にクロスハッチで示すように、鍔部２６ｄの外縁まで拡がっている。なお、図１０では接合面２６ａを示すクロスハッチが分かりにくくならないように、断面を示すハッチングを省いている。 In the push switch 2 of the second embodiment, the sheet member 23 is flat, and the joint surface 26a on one end side of the pusher member 26 is joined to the central portion thereof. The pusher member 26 includes a main body portion 26c having a contact surface 26b as a bottom surface, and a flange portion 26d extending outward from a side surface of the main body portion 26c at one end side. The joining surface 26a is formed by joining the body portion 26c and the flange portion 26d to the sheet member 23 at one end side. The joint surface 26a extends to the outer edge of the collar portion 26d as shown by a cross hatch in FIG. In FIG. 10, hatching showing a cross section is omitted so that the cross hatch showing the joint surface 26a is not easily understood.
第２実施形態のプッシュスイッチ２においても、当接面２６ｂを大きくすることなく、接合面２６ａの接合面積を大きくすることが好ましい。プッシュスイッチ２は、押し子部材２６の本体部２６ｃおよび鍔部２６ｄが一端側でシート部材２３に接合されているので、接合面２６ａが当接面２６ｂに比べて大きい面積となるように設けられている。このため、接合面積に比例して、シート部材２３との接合強度を高めることができる。これにより、小型化した場合にもシート部材２３との接合面積が大きくなるので、横押しされた場合でも接合面２６ａが剥がれにくい。したがって、横押しされた場合でも接合面２６ａが剥がれにくくなる。 Also in the push switch 2 of the second embodiment, it is preferable to increase the joint area of the joint surface 26a without enlarging the contact surface 26b. Since the main body portion 26c and the flange portion 26d of the pusher member 26 are joined to the sheet member 23 at one end side, the push switch 2 is provided so that the joining surface 26a has a larger area than the contact surface 26b. ing. Therefore, the joint strength with the sheet member 23 can be increased in proportion to the joint area. As a result, the joint area with the sheet member 23 is increased even when the size is reduced, so that the joint surface 26a is less likely to peel off even when laterally pressed. Therefore, the joining surface 26a is less likely to peel off even when laterally pushed.
なお、シート部材２３が平坦である場合、押圧操作によってシート部材２３が伸長する方向に弾性変形する。このため、操作荷重が大きくなって、操作感触が少し悪くなる傾向になる。また、可動接点部材２２の頂部２２ａから位置ずれした状態で押し子部材２６が配置されていると、操作感触が悪くなる。このように操作感触の点から、シート部材２３が平坦である場合、とくに、押し子部材２６が収容部２１ｂの中央に位置しているかどうかが重要であるが、外観上突出しないために、第１実施形態のプッシュスイッチ１に比べて押し子部材２６の位置が分かりにくい。しかし、第２実施形態のプッシュスイッチ２においても、シート部材２３が透光性の合成樹脂からなり、押し子部材２６が暗色系の合成樹脂からなる。したがって、透光性の合成樹脂からなるシート部材２３の上から暗色系の合成樹脂からなる押し子部材２６が視認可能であるため、表面が平坦な状態であっても押し子部材２６の配置が確認できる。 When the sheet member 23 is flat, the sheet member 23 is elastically deformed in the extending direction by the pressing operation. For this reason, the operation load is increased, and the operation feeling tends to be slightly deteriorated. Further, if the pusher member 26 is arranged in a state of being displaced from the top portion 22a of the movable contact member 22, the feel of operation becomes poor. From the point of operation feeling, when the sheet member 23 is flat, it is particularly important whether or not the pusher member 26 is located at the center of the accommodating portion 21b. The position of the pusher member 26 is difficult to understand as compared with the push switch 1 according to the first embodiment. However, also in the push switch 2 of the second embodiment, the sheet member 23 is made of a translucent synthetic resin and the pusher member 26 is made of a dark-colored synthetic resin. Therefore, since the pusher member 26 made of the synthetic resin of dark color can be visually recognized from the sheet member 23 made of the transparent synthetic resin, the pusher member 26 can be arranged even if the surface is flat. I can confirm.
以下、本実施形態としたことによる効果について説明する。 The effects of the present embodiment will be described below.
本実施形態のプッシュスイッチ２は、ドーム状に形成された可動接点部材２２と、収容部２１ｂを有するケース２１と、可動接点部材２２に接触可能な固定接点部材２４と、収容部２１ｂを覆うように配置されたシート部材２３と、シート部材２３と可動接点部材２２との間に配置された押し子部材２６と、を備える。そして、押し子部材２６は、一端側でシート部材２３に接合された接合面２６ａと、他端側で可動接点部材２２に当接する当接面２６ｂと、を有し、接合面２６ａが当接面２６ｂに比べて大きい面積となるように設けられている。 The push switch 2 of the present embodiment covers the movable contact member 22 formed in a dome shape, the case 21 having the accommodating portion 21b, the fixed contact member 24 contactable with the movable contact member 22, and the accommodating portion 21b. And a pusher member 26 disposed between the sheet member 23 and the movable contact member 22. The pusher member 26 has a joint surface 26a joined to the sheet member 23 on one end side and a contact surface 26b that abuts on the movable contact member 22 on the other end side. The area is larger than that of the surface 26b.
この構成によれば、小型化した場合にもシート部材２３と押し子部材２６との接合面積が大きくなるので、横押しされた場合でも接合面２６ａが剥がれにくい。したがって、横押しされた場合でも接合面２６ａが剥がれにくく、操作感触のよいプッシュスイッチ２を提供することができる。 According to this configuration, the joint area between the sheet member 23 and the pusher member 26 becomes large even when the size is reduced, so that the joint surface 26a is unlikely to peel off even when laterally pushed. Therefore, even if the push switch 2 is pushed laterally, the joining surface 26a is not easily peeled off, and the push switch 2 having a good operation feeling can be provided.
また、本実施形態のプッシュスイッチ２において、押し子部材２６は、当接面２６ｂを底面とする本体部２６ｃと、一端側で本体部２６ｃの側面から外方に延在する鍔部２６ｄと、を備える。そして、接合面２６ａは、本体部２６ｃおよび鍔部２６ｄが一端側でシート部材２３に接合されることによって形成される。 Further, in the push switch 2 of the present embodiment, the pusher member 26 includes a main body portion 26c having a contact surface 26b as a bottom surface, and a flange portion 26d extending outward from a side surface of the main body portion 26c at one end side, Equipped with. The joining surface 26a is formed by joining the body portion 26c and the flange portion 26d to the sheet member 23 at one end side.
この構成によれば、一端側で本体部２６ｃの側面から外方に延在する鍔部２６ｄも接合されることによって接合面２６ａが形成されているので、本体部２６ｃの底面である当接面２６ｂが大きくなってしまうことがなく、可動接点部材２２の反転動作を安定して行うことができる。 According to this configuration, the joint surface 26a is formed by joining the flange portion 26d that extends outward from the side surface of the main body portion 26c at one end side, so that the contact surface that is the bottom surface of the main body portion 26c. 26b does not become large, and the reversing operation of the movable contact member 22 can be stably performed.
また、本実施形態のプッシュスイッチ２において、鍔部２６ｄの厚さＴ２６がシート部材２３の厚さＴ２３の２倍以下であることが好ましい。 In addition, in the push switch 2 of the present embodiment, it is preferable that the thickness T26 of the collar portion 26d is not more than twice the thickness T23 of the sheet member 23.
鍔部２６ｄの厚さＴ２６がシート部材２３の厚さＴ２３の２倍以下であれば、押圧操作によるシート部材２３の変形に鍔部２６ｄが追随できるので、可動接点部材２２の反転動作を確実に行うことができる。 If the thickness T26 of the collar portion 26d is equal to or less than twice the thickness T23 of the sheet member 23, the collar portion 26d can follow the deformation of the sheet member 23 due to the pressing operation, so that the reversing operation of the movable contact member 22 can be reliably performed. It can be carried out.
また、本実施形態のプッシュスイッチ２において、押し子部材２６が暗色系の合成樹脂からなり、シート部材２３が透光性の合成樹脂からなることが好ましい。 Further, in the push switch 2 of the present embodiment, it is preferable that the pusher member 26 is made of a dark synthetic resin and the sheet member 23 is made of a translucent synthetic resin.
この構成によれば、透光性の合成樹脂からなるシート部材２３の上から暗色系の合成樹脂からなる押し子部材２６が視認可能であるため、表面が平坦な状態であっても押し子部材２６の配置が確認できる。また、シート部材２３が透光性の合成樹脂からなり、押し子部材２６が暗色系の合成樹脂からなるので、シート部材２３を通してレーザ光を照射することでレーザ溶着によって溶着させることが可能である。なお、第１実施形態のプッシュスイッチ１においても、シート部材１３を通してレーザ光を照射することでレーザ溶着によって押し子部材１６を溶着させることが可能である。 According to this structure, since the pusher member 26 made of the synthetic resin of dark color is visible from the top of the sheet member 23 made of the translucent synthetic resin, the pusher member 26 is flat even on the surface. The arrangement of 26 can be confirmed. Further, since the sheet member 23 is made of a translucent synthetic resin and the pusher member 26 is made of a dark synthetic resin, it is possible to perform laser welding by irradiating laser light through the sheet member 23. . Also in the push switch 1 of the first embodiment, the pusher member 16 can be welded by laser welding by irradiating the laser light through the sheet member 13.
以上のように、本発明の第１実施形態のプッシュスイッチ１および第２実施形態のプッシュスイッチ２を具体的に説明したが、本発明は上記の実施形態に限定されるものではなく、要旨を逸脱しない範囲で種々変更して実施することが可能である。例えば次のように変形して実施することができ、これらも本発明の技術的範囲に属する。 As described above, the push switch 1 according to the first embodiment and the push switch 2 according to the second embodiment of the present invention have been specifically described. However, the present invention is not limited to the above embodiments, and the gist thereof is not limited to the above. Various modifications can be made without departing from the scope. For example, the following modifications can be implemented and these also belong to the technical scope of the present invention.
