FIG. 3 is a view showing a first embodiment of a switch reversing spring constituting one embodiment of the switch device shown in FIG. 1, wherein FIG. 3A is a plan view, and FIG. 3B is a cross-sectional view of FIG. A side sectional view cut along line A, (c) is a back view.

スイッチ用反転ばねの第１実施形態を構成するスイッチ用反転ばね６は、図１，３に示すように、例えばばね性に富んだ金属板を板厚方向の一方に向けてドーム状に膨出成形して成るばね部材６ａと、このばね部材６ａに外部からの押圧力、すなわち上述の操作部７の押圧操作による押圧力を伝達する圧伝達部材、すなわち突起体６ｂとを備えている。この突起体６ｂは、例えば合成樹脂などの金属での成形加工が可能な材料より成り、上方に向かうに従って径寸法が次第に小さくなり、縦断面が台形を呈する頭部が切断された円錐形状から成っている。   As shown in FIGS. 1 and 3, the switch reversing spring 6 constituting the first embodiment of the switch reversing spring bulges, for example, a metal plate rich in springiness into a dome shape toward one side in the plate thickness direction. The formed spring member 6a and a pressure transmitting member that transmits a pressing force from the outside, that is, a pressing force by the pressing operation of the operation unit 7 described above, that is, a protrusion 6b are provided on the spring member 6a. The protrusion 6b is made of a material that can be molded with a metal such as a synthetic resin, and has a conical shape with a diameter that gradually decreases toward the upper side and a head whose longitudinal section has a trapezoidal shape is cut. ing.

ばね部材６ａは、押圧力を受けて反転し、押圧力が解かれることにより自己復元が可能であって、突起体６ｂが配置されていない下面側が銀めっきなどの接点材料が被覆されており、接点が一体形成された可動接点を構成している。そして、ばね部材６ａは、スイッチ基板２上の周辺固定接点４に常時接触する裾部を有し、膨出した頂部部分が中央固定接点３に接離可能に配置してある。このばね部材６ａは、頂部部分の下面側に小突起を突出させて形成した中央固定接点３に接離する接点部、例えば３つの接点部６ａ１，６ａ２，６ａ３をそれぞれ有するとともに、図３の（ａ）（ｃ）図に示すように、平面視で３つの接点部６ａ１，６ａ２，６ａ３にほぼ囲まれる領域内に配置され、当該ばね部材６ａと突起体６ｂとを一体的に連結保持する連結部６ａ４を有している。   The spring member 6a is reversed by receiving the pressing force, and can be self-recovered by releasing the pressing force, and the lower surface side where the protrusion 6b is not disposed is covered with a contact material such as silver plating, This constitutes a movable contact in which the contacts are integrally formed. The spring member 6 a has a skirt portion that always contacts the peripheral fixed contact 4 on the switch substrate 2, and the bulged top portion is disposed so as to be able to contact and separate from the central fixed contact 3. The spring member 6a has contact portions, for example, three contact portions 6a1, 6a2, and 6a3, which are in contact with and separated from the central fixed contact 3 formed by projecting small protrusions on the lower surface side of the top portion, respectively. a) (c) As shown in the drawings, the coupling is arranged in a region substantially surrounded by the three contact portions 6a1, 6a2, 6a3 in plan view, and integrally couples and holds the spring member 6a and the protrusion 6b. It has a part 6a4.

この連結部６ａ４は、操作部７の昇降方向に沿う押圧方向と交差する方向に起立させるように、ばね部材６ａの一部を切り起こし、先端を折り曲げ形成されたものから成っている。すなわち、この連結部６ａ４は、同図３の（ｂ）図に示すように、根元を押圧方向に沿うように上方に向けて起立させ、続いて押圧方向に対して傾斜させ、さらに続いて押圧方向と直交する形態を保つように、片持ち形状に形成してある。また、この連結部６ａ４は、突起体６ｂ内に埋め込み形成されてばね部材６ａと突起体６ｂとが他の部材を介さずに直接一体化されている。なお、上述した接点部６ａ１，６ａ２，６ａ３のそれぞれは、下方に向かうに従って次第に先細となる例えば半球に近似した形状に形成してある。   The connecting portion 6a4 is formed by cutting and raising a part of the spring member 6a and bending the tip so as to stand up in a direction intersecting with the pressing direction along the raising / lowering direction of the operation portion 7. That is, as shown in FIG. 3 (b), the connecting portion 6a4 is erected upward along the pressing direction, subsequently inclined with respect to the pressing direction, and further pressed. It is formed in a cantilever shape so as to maintain a shape orthogonal to the direction. Further, the connecting portion 6a4 is embedded in the protrusion 6b so that the spring member 6a and the protrusion 6b are directly integrated without any other member. Each of the contact portions 6a1, 6a2, and 6a3 described above is formed in a shape that approximates, for example, a hemisphere that gradually tapers in the downward direction.

さらに、図３の（ｂ）図に示すように、連結部６ａ４の根元から外側に向かう方向に位置するばね部材６ａの上面部分と、突起体６ｂの下端面との間には、隙間９を形成してある。この隙間９の形成領域は、突起体６ｂの下端面の径寸法、すなわち突起体６ｂが操作部７からの押圧力を受けた際に、ばね部材６ａと接触する接触領域６ｂ１の大きさに依存している。   Further, as shown in FIG. 3B, a gap 9 is formed between the upper surface portion of the spring member 6a located in the direction from the base of the connecting portion 6a4 to the outside and the lower end surface of the protrusion 6b. It is formed. The formation region of the gap 9 depends on the diameter of the lower end surface of the projection 6b, that is, the size of the contact region 6b1 that contacts the spring member 6a when the projection 6b receives a pressing force from the operation unit 7. is doing.

上述した粘着シート５には、スイッチ用反転ばね６のばね部材６ａの上面と、このばね部材６ａの連結部６ａ４を介してばね部材６ａに一体的に設けた突起体６ｂの上面とが接着されている。また、図１に示すように、上述した粘着シート５に予めエンボス加工などによって形成した凸部５ａ内に突起体６ｂが配置されている。この凸部５ａを設けることによって突起体６ｂを収容することができるので、脱落を確実に防止することができる。   The adhesive sheet 5 is bonded to the upper surface of the spring member 6a of the switch reversing spring 6 and the upper surface of the protrusion 6b provided integrally with the spring member 6a via the connecting portion 6a4 of the spring member 6a. ing. Moreover, as shown in FIG. 1, the protrusion 6b is arrange | positioned in the convex part 5a previously formed by the embossing etc. in the adhesive sheet 5 mentioned above. Protruding member 6b can be accommodated by providing this convex portion 5a, so that it is possible to reliably prevent dropping.

FIG. 5B is a side sectional view showing a state before the spring member is mounted on the mold, and FIG. 5B is a side sectional view showing a state when the spring member provided in the switch reversing spring is mounted on the mold during insert molding. c) The figure is a side sectional view showing a state in which the manufactured first embodiment of the switch reversing spring is taken out of the mold after the end of the insert molding, and (d) is an enlarged view of a part A in FIG. . FIG. 5 is a view showing a state in which the first embodiment of the switch reversing spring is continuously formed in one embodiment of the manufacturing method for manufacturing the switch reversing spring shown in FIG. FIG. 4A is a plan view, and FIG.

上述したスイッチ用反転ばね６の製造に際して、例えば図４の（ａ）図に示す金型８が用いられる。この金型８は、固定側キャビティ８ａと、この固定側キャビティ８ａに対向する可動コア８ｂとから成っている。   When manufacturing the switch reversing spring 6 described above, for example, a mold 8 shown in FIG. 4A is used. The mold 8 includes a fixed side cavity 8a and a movable core 8b facing the fixed side cavity 8a.

固定側キャビティ８ａは、ばね部材６ａの連結部６ａ４を含む部分が収容される収容部８ａ１と、この収容部８ａ１に連通し、射出成形機のノズルから収容部８ａ１へ溶融樹脂が導かれるゲート８ａ２とを備えている。可動コア８ｂは、固定側キャビティ８ａに対向する下端部に、ばね部材６ａの連結部６ａ４に当接可能な突出部８ｂ１を有している。この突出部８ｂ１の近傍を含む下端部は、固定側キャビティ８ａの上面を形成する平坦面に対向する平坦面８ｂ２に形成されている。また、可動コア８ｂには、インサート成形された後に、可動コア８ｂに貼り付いたスイッチ用反転ばね６を可動コア８ｂから分離させるイジェクトピン８ｂ３を、可動コア８ｂの平坦面８ｂ２から下方へ突出可能に設けてある。   The fixed-side cavity 8a includes an accommodating portion 8a1 that accommodates a portion including the connecting portion 6a4 of the spring member 6a, and a gate 8a2 that communicates with the accommodating portion 8a1 and guides the molten resin from the nozzle of the injection molding machine to the accommodating portion 8a1. And. The movable core 8b has a protruding portion 8b1 that can come into contact with the connecting portion 6a4 of the spring member 6a at the lower end facing the fixed cavity 8a. The lower end including the vicinity of the protrusion 8b1 is formed on a flat surface 8b2 that faces the flat surface that forms the upper surface of the fixed cavity 8a. Further, an eject pin 8b3 for separating the switch reversing spring 6 attached to the movable core 8b from the movable core 8b after the insert molding is formed on the movable core 8b can protrude downward from the flat surface 8b2 of the movable core 8b. Is provided.

例えばプレス加工によって、接点部６ａ１，６ａ２，６ａ３とともに、連結部６ａ４が同時に形成された縦断面が弓形状に湾曲して成るばね部材６ａに対して、インサート成形によって突起体６ｂを設けてスイッチ用反転ばね６を製造する場合、はじめに図４の（ａ）図に示すように、固定側キャビティ８ａと可動コア８ｂとの間に、連結部６ａ４が固定側キャビティ８ａの収容部８ａ１に対向するようにばね部材６ａが配置される。   For example, a pressing member 6a1, 6a2, 6a3 and a spring member 6a in which a longitudinal section formed simultaneously with a connecting portion 6a4 is curved in a bow shape is provided with a protrusion 6b by insert molding for a switch. When the reversal spring 6 is manufactured, first, as shown in FIG. 4A, the connecting portion 6a4 is opposed to the accommodating portion 8a1 of the fixed side cavity 8a between the fixed side cavity 8a and the movable core 8b. The spring member 6a is disposed on the surface.

この状態から、図４の（ｂ）図に示すように、ばね部材６ａの連結部６ａ４を固定側キャビティ８ａの収容部８ａ１内に収容させ、可動コア８ｂの突出部８ｂ１を収容部８ａ１内の連結部６ａ４に当接させるようにして、また、可動コア８ｂの下端部を形成する平坦面８ｂ２で湾曲していたばね部材６ａの全体を平らに延ばすようにして、可動コア８ｂを固定側キャビティ８ａに対して押圧させる。この状態において、固定側キャビティ８ａのゲート８ａ２から溶融樹脂を注入し、収容部８ａ１にこの溶融樹脂を充填して固化させると、図４の（ｃ）図に示すように、ばね部材６ａの連結部６ａ４に合成樹脂より成る突起体６ｂが連結保持されたスイッチ用反転ばね６が出来上がる。   From this state, as shown in FIG. 4B, the connecting portion 6a4 of the spring member 6a is accommodated in the accommodating portion 8a1 of the fixed cavity 8a, and the protruding portion 8b1 of the movable core 8b is accommodated in the accommodating portion 8a1. The movable core 8b is fixed to the fixed-side cavity 8a so as to abut on the connecting portion 6a4 and so that the entire spring member 6a curved at the flat surface 8b2 forming the lower end of the movable core 8b extends flat. Press against. In this state, when molten resin is injected from the gate 8a2 of the fixed side cavity 8a, and the container 8a1 is filled with the molten resin and solidified, as shown in FIG. 4 (c), the connection of the spring member 6a is achieved. The switch reversing spring 6 is completed in which the projection 6b made of synthetic resin is connected and held to the portion 6a4.

この成形時に可動コア８ｂの突出部８ｂ１が連結部６ａ４に当接していることで、金型内に充填される樹脂流動に抗して連結部６ａ４を支えることができるので、収容部８ａ１内で連結部６ａ４の上下面と側面とに樹脂を行き渡らせることが可能となり、上下面および側面が樹脂で覆われるように埋め込むことができ、強固に保持させることができる。   Since the protrusion 8b1 of the movable core 8b is in contact with the connecting portion 6a4 at the time of molding, the connecting portion 6a4 can be supported against the resin flow filled in the mold. The resin can be spread over the upper and lower surfaces and the side surfaces of the connecting portion 6a4, and the upper and lower surfaces and the side surfaces can be embedded so as to be covered with the resin, and can be firmly held.

また、図４の（ｂ）図に示すように、突出部８ｂ１の周囲は平坦面８ｂ２よりも一段高く形成されて、ばね部材６ａの連結部６ａ４を切り起こした開口部分に挿通されることで、成形時にこの開口部分を塞ぐようになっており、接点部６ａ１，６ａ２，６ａ３側に向けて樹脂がはみだすことがなく、固定接点との接触不良を防止することができる。   Further, as shown in FIG. 4B, the periphery of the protruding portion 8b1 is formed one step higher than the flat surface 8b2, and is inserted into the opening portion that cuts and raises the connecting portion 6a4 of the spring member 6a. The opening is closed at the time of molding, and the resin does not protrude toward the contact portions 6a1, 6a2, and 6a3, and contact failure with the fixed contact can be prevented.

なお、可動コア８ｂの下端部を形成する平坦面８ｂ２に貼り付いたスイッチ用反転ばね６は、同図４の（ｃ）図に示すように、イジュクトピン８ｂ３の先端を可動コア８ｂの平坦面８ｂ２から突出させることにより、可動コア８ｂから分離することができる。このときのばね部材６ａの、縦断面弓形状への復元力によって、連結部６ａ４の根元から外側に向かう方向に位置するばね部材６ａの部分が、突起体６ｂから分離され、同図４の（ｄ）図に示すように、連結部６ａの根元から外側に向かう方向に位置するばね部材６ａの部分と、突起体６ｂとの間に上述した隙間９が形成される。   As shown in FIG. 4C, the switch reversing spring 6 attached to the flat surface 8b2 forming the lower end portion of the movable core 8b has the tip of the eject pin 8b3 at the flat surface 8b2 of the movable core 8b. By projecting from the movable core 8b, the movable core 8b can be separated. 4 is separated from the protrusion 6b by the restoring force of the spring member 6a to the bow shape of the longitudinal section at this time, and the portion of the spring member 6a located in the direction from the base of the connecting portion 6a4 to the outside is separated. d) As shown in the figure, the gap 9 described above is formed between the protrusion 6b and the portion of the spring member 6a located in the direction from the base of the connecting portion 6a to the outside.

上述したスイッチ用反転ばね６は、例えば図５に示すように連続的に製造される。すなわち、ばね部材６ａが複数形成されたフープ材１０を矢印１０ａ方向に移動させ、図４に示した固定側キャビティ８ａと可動コア８ｂとから成る金型８を用いて、スイッチ用反転ばね６の製造が連続的に実施されるようになっている。   The switch reversing spring 6 described above is continuously manufactured, for example, as shown in FIG. That is, the hoop material 10 formed with a plurality of spring members 6a is moved in the direction of the arrow 10a, and the die 8 comprising the fixed side cavity 8a and the movable core 8b shown in FIG. Manufacturing is carried out continuously.

［スイッチ用反転ばねの第１実施形態を含むスイッチ装置の一実施形態の動作］
上述のように構成した図１に示すスイッチ装置において、操作部７が押圧操作されない初期状態では、スイッチ基板２の中央固定接点３と、可動接点を構成するスイッチ用反転ばね６のばね部材６の接点部６ａ１，６ａ２，６ａ３とが離れた状態に保持されるので、中央固定接点３と周辺固定接点４との間が電気的に遮断され、スイッチオフとなっている。 [Operation of One Embodiment of Switch Device Including First Embodiment of Reversing Spring for Switch]
In the switch device shown in FIG. 1 configured as described above, in the initial state where the operation unit 7 is not pressed, the central fixed contact 3 of the switch substrate 2 and the spring member 6 of the switch reversing spring 6 constituting the movable contact are provided. Since the contact portions 6a1, 6a2 and 6a3 are held in a separated state, the central fixed contact 3 and the peripheral fixed contact 4 are electrically cut off and switched off.

この状態から、操作部７を押圧操作して下降させると、操作部７による押圧力が粘着シート５の凸部５ａを介してスイッチ用反転ばね６の突起体６ｂに伝えられ、その押圧力によって突起体６ｂの下端面が隙間９を無くすように可動接点を構成するばね部材６ａの上面に当接し、引き続いてばね部材６ａが反転して、このばね部材６ａの接点部６ａ１，６ａ２，６ａ３が中央固定接点３に接触する。これによって、中央固定接点３と周辺固定接点４とがばね部材６ａを介して導通し、スイッチオンとなる。また、上述したばね部材６ａの反転時に、クリック感触が得られる。   From this state, when the operating portion 7 is pressed and lowered, the pressing force by the operating portion 7 is transmitted to the protrusion 6b of the switch reversing spring 6 through the convex portion 5a of the adhesive sheet 5, and by the pressing force, The lower end surface of the protrusion 6b comes into contact with the upper surface of the spring member 6a constituting the movable contact so as to eliminate the gap 9, and then the spring member 6a is reversed, so that the contact portions 6a1, 6a2, 6a3 of the spring member 6a Contact the central fixed contact 3. As a result, the central fixed contact 3 and the peripheral fixed contact 4 are conducted through the spring member 6a, and the switch is turned on. Further, a click feeling can be obtained when the above-described spring member 6a is reversed.

また、このような状態から、操作部７の押圧力を解くと、スイッチ用反転ばね６のばね部材６ａの保有する弾性、すなわち復元力により、ばね部材６ａが復元し、ばね部材６ａと突起体６ｂとの間に隙間９が形成されるとともに、このばね部材６ａの接点部６ａ１，６ａ２，６ａ３が中央固定接点３から離れる。したがって、中央固定接点３と周辺固定接点４との間が電気的に遮断され、再びスイッチオフとなる。   Further, when the pressing force of the operating portion 7 is released from such a state, the spring member 6a is restored by the elasticity, ie, the restoring force, of the spring member 6a of the switch reversing spring 6, and the spring member 6a and the projecting body A gap 9 is formed with respect to 6b, and the contact portions 6a1, 6a2, 6a3 of the spring member 6a are separated from the central fixed contact 3. Therefore, the central fixed contact 3 and the peripheral fixed contact 4 are electrically disconnected, and the switch is turned off again.

［スイッチ用反転ばねの第１実施形態を含むスイッチ装置の一実施形態の効果］
以上のように構成したスイッチ装置の一実施形態によれば、操作部７による押圧力が伝えられるスイッチ用反転ばね６の突起体６ｂとばね部材６ａとを、ばね部材６ａの一部である連結部６ａ４によって一体化してあるので、スイッチ用反転ばね６の突起体６ｂとばね部材６ａとの間の密着性を高めることができる。これによって、突起体６ｂをばね部材６ａの上に強い保持強度で保持させることができる。したがって、経時的に突起体６ｂに繰り返して押圧力が与えられるような場合でも、ばね部材６ａからの突起体６ｂの脱落を防ぐことができ、優れた耐久性が得られ、構造上の高い信頼性を確保することができる。 [Effect of One Embodiment of Switch Device Including First Embodiment of Reversing Spring for Switch]
According to one embodiment of the switch device configured as described above, the protrusion 6b of the switch reversing spring 6 and the spring member 6a, to which the pressing force by the operation portion 7 is transmitted, are connected as a part of the spring member 6a. Since it is integrated by the part 6a4, the adhesion between the protrusion 6b of the switch reversing spring 6 and the spring member 6a can be enhanced. Thereby, the protrusion 6b can be held on the spring member 6a with a strong holding strength. Therefore, even when a pressing force is repeatedly applied to the protrusion 6b over time, the protrusion 6b can be prevented from falling off from the spring member 6a, and excellent durability can be obtained and the structure has high reliability. Sex can be secured.

また、スイッチ用反転ばね６の合成樹脂より成る突起体６ｂ内に、ばね部材６ａの連結部６ａ４を埋め込むようにしたことから、突起体６ｂとばね部材６ａとの間の密着性をさらに高めることができ、突起体６ｂに対するより強い保持力の確保に貢献する。   Further, since the connecting portion 6a4 of the spring member 6a is embedded in the protrusion 6b made of synthetic resin of the switch reversing spring 6, the adhesion between the protrusion 6b and the spring member 6a is further enhanced. This contributes to securing a stronger holding force for the protrusion 6b.

また、スイッチ用反転ばね６の連結部６ａ４は、ばね部材６ａの一部を、操作部７の押圧方向と交差する方向に起立させて成り、ばね部材６ａからの突起体６ｂの抜け止め部材を形成することから、突起体６ｂの脱落を確実に防ぐことができる。   The connecting portion 6a4 of the switch reversing spring 6 is formed by raising a part of the spring member 6a in a direction intersecting the pressing direction of the operation portion 7, and serves as a retaining member for the protrusion 6b from the spring member 6a. Since it forms, the drop-off of the protrusion 6b can be reliably prevented.

また、スイッチ用反転ばね６の連結部６ａ４の根元から外側に向かう方向に位置するばね部材６ａの部分と、突起体６ｂとの間に隙間９を形成してあることから、この隙間９によって湾曲したばね部材６ａの反転動作を突起体６ｂによって拘束されることなく行なわせることができ、優れた反転性能を確保できる。これにより、良好なスイッチオン・オフ性能が得られるとともに、ばね部材６ａの長寿命化を実現できる。また、隙間９の形成領域を適宜に変更することにより、すなわち、ばね部材６ａに対向する突起体６ｂの部分の寸法を適宜に変更することにより、ばね部材６ａの反転時における突起体６ｂとばね部材６ａとの接触面積を変えることができる。これに応じて、ばね部材６ａの反転に要する押圧力、すなわち、このスイッチ用反転ばね６の作動力を、このスイッチ用反転ばね６が備えられるスイッチ装置のそれぞれに相応する望ましい大きさの作動力に変更させることができ、それぞれのスイッチ装置に好適な優れた操作性を確保できる。   Further, since the gap 9 is formed between the protrusion 6b and the portion of the spring member 6a located in the direction from the base of the connecting portion 6a4 of the switch reversing spring 6 to the outside, the curve 9 is curved. The reversing operation of the spring member 6a can be performed without being restrained by the protrusion 6b, and excellent reversing performance can be ensured. Thereby, it is possible to obtain a good switch on / off performance and to extend the life of the spring member 6a. Further, by appropriately changing the formation region of the gap 9, that is, by appropriately changing the size of the portion of the protrusion 6b facing the spring member 6a, the protrusion 6b and the spring when the spring member 6a is reversed are changed. The contact area with the member 6a can be changed. In response to this, the pressing force required for reversing the spring member 6a, that is, the operating force of the switch reversing spring 6 is set to a desired amount of operating force corresponding to each of the switch devices provided with the switch reversing spring 6. Therefore, excellent operability suitable for each switch device can be secured.

また、スイッチ用反転ばね６のばね部材６ａは、接点部６ａ１，６ａ２，６ａ３を有する可動接点を兼ねるので、中央固定接点３に接離する可動接点を別に設ける必要がなく、このスイッチ用反転ばね６が備えられるスイッチ装置の部品数を少なくすることができる。   Further, since the spring member 6a of the switch reversing spring 6 also serves as a movable contact having the contact portions 6a1, 6a2, 6a3, there is no need to separately provide a movable contact that contacts and separates from the central fixed contact 3, and this switch reversing spring The number of parts of the switch device provided with 6 can be reduced.

また、スイッチ用反転ばね６のばね部材６ａが、粘着シート５によって保持されるようになっているので、スイッチ装置の製作に際して、複数のスイッチ用反転ばね６をスイッチ基板２に組み込む際には、複数のスイッチ用反転ばね６を保持した状態の粘着シート５をスイッチ基板２に接着すればよいので、スイッチ基板２へのスイッチ用反転ばね６の組み込みが容易である。   Since the spring member 6a of the switch reversing spring 6 is held by the adhesive sheet 5, when the switch reversing springs 6 are assembled into the switch board 2 when the switch device is manufactured, Since the adhesive sheet 5 holding a plurality of switch reversing springs 6 may be bonded to the switch substrate 2, the switch reversing springs 6 can be easily incorporated into the switch substrate 2.

［スイッチ用反転ばねの製造方法の一実施形態の効果］
また、図４，５に示す製造方法の一実施形態によれば、固定キャビティ８ａと可動コア８ｂを有する金型８を用い、固定キャビティ８ａの収容部８ａ１内にばね部材６ａの連結部６ａ４を収容し、固定側キャビティ８ａと可動コア８ｂとによってばね部材６ａを挟圧し、この状態で固定側キャビティ８ａの収容部８ａ１内に溶融樹脂を充填して、圧伝達部材を構成する突起体６ｂを形成するようにしてあることから、ばね部材６の連結部６ａ４を突起体６ｂに埋め込んで成るスイッチ用反転ばね６を容易に、連続的に、能率よく製造することができる。 [Effect of one embodiment of manufacturing method of reversal spring for switch]
4 and 5, the mold 8 having the fixed cavity 8a and the movable core 8b is used, and the connecting portion 6a4 of the spring member 6a is provided in the accommodating portion 8a1 of the fixed cavity 8a. The spring member 6a is clamped between the fixed side cavity 8a and the movable core 8b, and the molten resin is filled in the storage portion 8a1 of the fixed side cavity 8a in this state, so that the protrusion 6b constituting the pressure transmission member is provided. Since it is formed, the switch reversing spring 6 in which the connecting portion 6a4 of the spring member 6 is embedded in the protrusion 6b can be manufactured easily, continuously and efficiently.

また、図４の（ｂ）図に示すように、スイッチ用反転ばね６のばね部材６ａを、金型８の固定側キャビティ８ａの上面と、可動コア８ｂの下端部を形成する平坦面８ｂとによって平らに延ばした状態でインサート成形し、連結部６ａが埋め込まれた突起体６ｂの形成後、製造されたスイッチ用反転ばね６の金型８からの取り出し時に、ばね部材６ａの復元力によってこのばね部材６ａが復元し、これによってばね部材６ａと突起体６ｂとの間に隙間９が形成される。すなわち、この隙間９の形成を、スイッチ用反転ばね６の製造過程の中で、容易に形成することができる。このようなばね部材６ａと突起体６ｂとの間に形成される隙間９によって、上述のように、ばね部材６ａの反転動作を突起体６ｂによって拘束されることなく行なわせることができ、優れた反転性能を確保でき、良好なスイッチオン・オフ性能が得られるとともに、ばね部材６ａの長寿命化を実現できる。また、ばね部材６ａに対向する突起体６ｂの部分の寸法を適宜に変更することにより、ばね部材６ａの反転に要する押圧力、すなわちスイッチ用反転ばね６の作動力を、このスイッチ用反転ばね６が備えられるスイッチ装置のそれぞれに相応する大きさの作動力に変更させることができ、それぞれのスイッチ装置に好適な優れた操作性を確保できる。   Further, as shown in FIG. 4B, the spring member 6a of the switch reversing spring 6 includes an upper surface of the fixed-side cavity 8a of the mold 8 and a flat surface 8b that forms the lower end of the movable core 8b. After forming the protrusion 6b in which the connecting portion 6a is embedded after the insert is molded in a state of being flattened by the above-described method, when the manufactured switch reversing spring 6 is taken out from the mold 8, the restoring force of the spring member 6a The spring member 6a is restored, whereby a gap 9 is formed between the spring member 6a and the protrusion 6b. That is, the gap 9 can be easily formed during the manufacturing process of the switch reversal spring 6. The gap 9 formed between the spring member 6a and the protrusion 6b can cause the reversing operation of the spring member 6a to be performed without being constrained by the protrusion 6b as described above. The reversal performance can be secured, good switch on / off performance can be obtained, and the life of the spring member 6a can be extended. Further, by appropriately changing the size of the projection 6b facing the spring member 6a, the pressing force required for reversing the spring member 6a, that is, the operating force of the switch reversing spring 6 can be changed. Therefore, it is possible to change the operating force to a magnitude corresponding to each of the switch devices, and to ensure excellent operability suitable for each switch device.

6A and 6B are diagrams showing a second embodiment of the switch reversal spring according to the present invention, in which FIG. 6A is a plan view, and FIG. 6B is a side cross-sectional view taken along line BB in FIG. The figure and (c) figure are back views.

この図６に示すスイッチ用反転ばねの第２実施形態を構成するスイッチ用反転ばね１１も、上述した第１実施形態に係るスイッチ用反転ばね６と同様に、例えば可動接点から成り、ドーム状に膨出した導電性金属板から成るばね部材１１ａと、このばね部材１１ａに外部からの押圧力を伝達する圧伝達部材、すなわち突起体１１ｂを備えている。この突起体１１ｂは、例えば合成樹脂より成り、上方に向かうに従って径寸法が次第に小さくなり、縦断面が台形を呈する頭部が切断された円錐形状から成っている。ばね部材１１ａは、押圧力を受けると反転し、押圧力が解かれることにより自己復元可能となっている。   The switch reversing spring 11 constituting the second embodiment of the switch reversing spring shown in FIG. 6 is also composed of, for example, a movable contact, like a dome, like the switch reversing spring 6 according to the first embodiment described above. A spring member 11a made of an expanded conductive metal plate and a pressure transmission member for transmitting a pressing force from the outside to the spring member 11a, that is, a protrusion 11b are provided. The protrusion 11b is made of, for example, a synthetic resin, and has a conical shape in which a diameter dimension is gradually reduced toward the upper side and a head having a trapezoidal longitudinal section is cut. The spring member 11a reverses when it receives a pressing force, and can self-recover by releasing the pressing force.

このばね部材１１ａは、頂部部分の下面側に固定接点に接離する接点部、例えば３つの接点部１１ａ１，１１ａ２，１１ａ３をそれぞれ有するとともに、同図６の（ａ）（ｃ）に示すように、平面視で３つの接点部６ａ１，６ａ２，６ａ３にほぼ囲まれる領域内に配置され、当該ばね部材１１ａと突起体１１ｂとを一体的に連結保持する連結部１１ａ４を有している。この連結部１１ａ４は、突起体１１ｂに与えられる押圧力の方向と交差する方向に起立させるように、ばね部材１１ａの一部を、例えばバーリング加工によって、先細の中空管状に形成してある。すなわち、この連結部１１ａ４を同図６の（ｂ）図に示すように、縦断面の形状が、根元を押圧方向に沿うように上方に向けて起立させ、続いて押圧方向に対して傾斜する形状となる筒形状に形成してある。このように先細バーリングに形成した連結部１１ａ４は、ばね部材１１ａからの突起体１１ｂの抜け止め部材を形成している。接点部１１ａ１，１１ａ２，１１ａ３のそれぞれは、下方に向かうに従って次第に先細となる例えば半球に近似した形状に形成してある。また、この連結部１１ａ４は、突起体１１ｂ内にインサート成形によって埋め込まれている。この第２実施形態に係るスイッチ用反転ばね１１においては、連結部１１ａ４を中空管状に形成したので、連結部１１ａ４の全周の内側と外側に樹脂を充填することができ、強固に保持させることができる。   The spring member 11a has contact portions, for example, three contact portions 11a1, 11a2, and 11a3 that contact and separate from the fixed contact on the lower surface side of the top portion, respectively, and as shown in FIGS. 6 (a) and 6 (c). And a connecting portion 11a4 which is disposed in a region substantially surrounded by the three contact portions 6a1, 6a2 and 6a3 in plan view and integrally connects and holds the spring member 11a and the protrusion 11b. A part of the spring member 11a is formed into a tapered hollow tubular shape by, for example, burring so that the connecting portion 11a4 is erected in a direction that intersects the direction of the pressing force applied to the protrusion 11b. That is, as shown in FIG. 6 (b), the connecting section 11a4 has a vertical cross-sectional shape that rises upward so that the root is along the pressing direction, and then tilts with respect to the pressing direction. It is formed in the shape of a cylinder. Thus, the connection part 11a4 formed in the taper burring forms the retaining member of the protrusion 11b from the spring member 11a. Each of the contact portions 11a1, 11a2, and 11a3 is formed in a shape that approximates, for example, a hemisphere that gradually tapers as it goes downward. Further, the connecting portion 11a4 is embedded in the protrusion 11b by insert molding. In the switch reversing spring 11 according to the second embodiment, since the connecting portion 11a4 is formed in a hollow tubular shape, the inner and outer sides of the entire circumference of the connecting portion 11a4 can be filled with resin and held firmly. Can do.

さらに、同図６の（ｂ）図に示すように、連結部１１ａ４の根元から外側に向かう方向に位置するばね部材１１ａの上面部分と、突起体１１ｂの下端面との間には、隙間１２を形成してある。この隙間１２の形成領域は、突起体１１ｂの下端面の径寸法、すなわち突起体１１ｂが押圧力を受けた際に、ばね部材１１ａと接触する接触領域１１ｂ１の大きさに依存している。この接触領域１１ｂ１は、上述した図３の（ｂ）図に示すスイッチ用反転ばね６ａと一体化された突起体６ｂにおける接触領域６ｂ１とほぼ同等に設定してある。すなわち、第２実施形態に係るスイッチ用反転ばね１１の突起体１１ｂの大きさを、上述した第１実施形態に係るスイッチ用反転ばね６の突起体６ｂとほぼ同等に設定してある。   Further, as shown in FIG. 6B, there is a gap 12 between the upper surface portion of the spring member 11a located in the direction from the base of the connecting portion 11a4 toward the outside and the lower end surface of the protrusion 11b. Is formed. The formation area of the gap 12 depends on the diameter of the lower end surface of the protrusion 11b, that is, the size of the contact area 11b1 that contacts the spring member 11a when the protrusion 11b receives a pressing force. This contact region 11b1 is set to be substantially equivalent to the contact region 6b1 in the protrusion 6b integrated with the switch reversing spring 6a shown in FIG. That is, the size of the protrusion 11b of the switch reversing spring 11 according to the second embodiment is set to be approximately equal to the protrusion 6b of the switch reversing spring 6 according to the first embodiment described above.

このように構成される第２実施形態に係るスイッチ用反転ばね１１も、上述した図１に示す中央固定接点３及び周辺固定接点４が形成されたスイッチ基板２を備えたスイッチ装置の可動接点として設けることができる。また、図４，５に示した製造方法の一実施形態によって製造することもできる。   The switch reversing spring 11 according to the second embodiment configured as described above is also used as a movable contact of the switch device including the switch substrate 2 on which the central fixed contact 3 and the peripheral fixed contact 4 shown in FIG. 1 are formed. Can be provided. Moreover, it can also manufacture by one Embodiment of the manufacturing method shown to FIG.

この第２実施形態に係るスイッチ用反転ばね１１も、第１実施形態に係るスイッチ用反転ばね６と同様に、突起体１１ｂをばね部材１１ａに一体的に連結保持させる連結部１１ａ４をばね部材１１ａに備えるとともに、連結部１１ａ４が、ばね部材１１ａからの突起体１１ｂの脱落を防ぐ抜け止め部材を形成することから、また、ばね部材１１ａと突起体１１ｂとの間に隙間１２を形成してあることから、第１実施形態に係るスイッチ用反転ばね６と同様の作用効果を得ることができる。なお、この第２実施形態に係るスイッチ用反転ばね１１の突起体１１ｂの大きさを、第１実施形態に係るスイッチ用反転ばね６の突起体６ｂとほぼ同等に設定してあることから、この第２実施形態に係るスイッチ用反転ばね１１を反転させる押圧力、すなわちスイッチ用反転ばね１１の作動力を、第１実施形態に係るスイッチ用反転ばね６の作動力とほぼ同等にすることができる。   Similarly to the switch reversing spring 6 according to the first embodiment, the switch reversing spring 11 according to the second embodiment also includes a connecting portion 11a4 that integrally connects and holds the protrusion 11b to the spring member 11a. In addition, the connecting portion 11a4 forms a retaining member that prevents the protrusion 11b from falling off the spring member 11a, and a gap 12 is formed between the spring member 11a and the protrusion 11b. Therefore, the same effect as the switch reversing spring 6 according to the first embodiment can be obtained. The size of the protrusion 11b of the switch reversing spring 11 according to the second embodiment is set to be approximately equal to the size of the protrusion 6b of the switch reversing spring 6 according to the first embodiment. The pressing force for reversing the switch reversing spring 11 according to the second embodiment, that is, the operating force of the switch reversing spring 11 can be made substantially equal to the operating force of the switch reversing spring 6 according to the first embodiment. .

［スイッチ用反転ばねの第３実施形態］
図７は本発明に係るスイッチ用反転ばねの第３実施形態を示す図で、（ａ）図は平面図、（ｂ）図は（ａ）図のＣ−Ｃ線に沿って切断した側断面図、（ｃ）図は裏面図である。 [Third embodiment of reversing spring for switch]
7A and 7B are views showing a third embodiment of the switch reversing spring according to the present invention, in which FIG. 7A is a plan view, and FIG. 7B is a sectional side view taken along the line CC in FIG. The figure and (c) figure are back views.

この図７に示すスイッチ用反転ばねの第３実施形態を構成するスイッチ用反転ばね１３も、上述した第１実施形態に係るスイッチ用反転ばね６と同様に、例えば可動接点から成り、ドーム状に膨出した導電性金属板から成るばね部材１３ａと、このばね部材１３ａに外部からの押圧力を伝達する圧伝達部材、すなわち突起体１３ｂとを備えている。この突起体１３ｂは、例えば合成樹脂より成り、上方に向かうに従って径寸法が次第に小さくなり、縦断面が台形を呈する頭部が切断された円錐形状から成っている。ばね部材１３ａは、押圧力を受けると反転し、押圧力が解かれることにより自己復元可能となっている。   Similarly to the switch reversing spring 6 according to the first embodiment described above, the switch reversing spring 13 constituting the third embodiment of the switch reversing spring shown in FIG. A spring member 13a made of an expanded conductive metal plate and a pressure transmission member for transmitting a pressing force from the outside to the spring member 13a, that is, a protrusion 13b are provided. The protrusion 13b is made of, for example, a synthetic resin, and has a conical shape in which a diameter dimension is gradually reduced toward the upper side, and a head having a trapezoidal longitudinal section is cut. The spring member 13a is reversed when it receives a pressing force, and can be self-recovered by releasing the pressing force.

このばね部材１３ａは、頂部部分の下面側に固定接点に接離する接点部、例えば３つの接点部１３ａ１，１３ａ２，１３ａ３をそれぞれ有するとともに、同図７の（ａ）（ｃ）図に示すように、平面視で３つの接点部１３ａ１，１３ａ２，１３ａ３にほぼ囲まれる領域内に配置され、当該ばね部材１３ａと突起体１３ｂとを一体的に連結保持する連結部１３ａ４を有している。この連結部１３ａ４は、突起体１３ｂに与えられる押圧力の方向と交差する方向に起立させるように、ばね部材１３ａの一部を、例えばバーリング加工によって先細の中空管状に形成してある。すなわち、この連結部１３ａ４を同図７の（ｂ）図に示すように、縦断面の形状が、根元を押圧方向に沿うように起立させ、続いて押圧方向に対して傾斜する形状となる筒形状に形成してある。このように先細バーリングに形成した連結部１３ａ４は、ばね部材１３ａからの突起体１３ｂの抜け止め部材を形成している。接点部１３ａ１，１３ａ２，１３ａ３のそれぞれは、下方に向かうに従って次第に先細となる例えば半球に近似した形状に形成してある。また、この連結部１３ａ４は、突起体１３ｂ内にインサート成形によって埋め込まれている。   The spring member 13a has contact portions, for example, three contact portions 13a1, 13a2, and 13a3, which are in contact with and away from the fixed contact, on the lower surface side of the top portion, respectively, as shown in FIGS. 7 (a) and 7 (c). Further, it has a connecting portion 13a4 which is disposed in a region substantially surrounded by the three contact portions 13a1, 13a2 and 13a3 in plan view and integrally connects and holds the spring member 13a and the protrusion 13b. A part of the spring member 13a is formed into a tapered hollow tube by, for example, burring so that the connecting portion 13a4 is erected in a direction that intersects the direction of the pressing force applied to the protrusion 13b. That is, as shown in FIG. 7 (b), the connecting portion 13a4 is a cylinder in which the shape of the longitudinal section is a shape in which the root is erected along the pressing direction and subsequently inclined with respect to the pressing direction. It is formed into a shape. Thus, the connection part 13a4 formed in the tapered burring forms a retaining member for the protrusion 13b from the spring member 13a. Each of the contact portions 13a1, 13a2, and 13a3 is formed in a shape that approximates, for example, a hemisphere that gradually tapers as it goes downward. Further, the connecting portion 13a4 is embedded in the protrusion 13b by insert molding.

さらに、同図７の（ｂ）図に示すように、連結部１３ａ４の根元から外側に向かう方向に位置するばね部材１３ａの上面部分と、突起体１３ｂの下端面との間には、わずかながら隙間を形成してある。この隙間の形成領域は、突起体１３ｂの下端面の径寸法、すなわち突起体１３ｂが押圧力を受けた際に、ばね部材１３ａと接触する接触領域１３ｂ１の大きさに依存している。この接触領域１３ｂ１は、上述した図３の（ｂ）図に示す第１実施形態に係るばね部材６ａと一体化された突起体６ｂにおける接触領域６ｂ１よりも小さく設定してある。すなわち、この第３実施形態に係るスイッチ用反転ばね１３の突起体１３ｂの大きさは、上述した第１実施形態に係るスイッチ用反転ばね６の突起体６ｂに比べて小さく形成してある。   Furthermore, as shown in FIG. 7B, there is a slight gap between the upper surface portion of the spring member 13a located in the direction from the base of the connecting portion 13a4 toward the outside and the lower end surface of the protrusion 13b. A gap is formed. The formation area of the gap depends on the diameter of the lower end surface of the protrusion 13b, that is, the size of the contact area 13b1 that contacts the spring member 13a when the protrusion 13b receives a pressing force. This contact area 13b1 is set smaller than the contact area 6b1 in the protrusion 6b integrated with the spring member 6a according to the first embodiment shown in FIG. That is, the size of the protrusion 13b of the switch reversing spring 13 according to the third embodiment is smaller than the protrusion 6b of the switch reversing spring 6 according to the first embodiment described above.

このように構成される第３実施形態に係るスイッチ用反転ばね１３も、上述した図１に示す中央固定接点３及び周辺固定接点４が形成されたスイッチ基板２を備えたスイッチ装置の可動接点として設けることができる。また、図４，５に示した製造方法の一実施形態によって製造することもできる。   The switch reversing spring 13 according to the third embodiment configured as described above is also used as a movable contact of the switch device including the switch substrate 2 on which the central fixed contact 3 and the peripheral fixed contact 4 shown in FIG. 1 are formed. Can be provided. Moreover, it can also manufacture by one Embodiment of the manufacturing method shown to FIG.

この第３実施形態に係るスイッチ用反転ばね１３も、第１実施形態に係るスイッチ用反転ばね６と同様に、突起体１３ｂをばね部材１３ａに一体的に連結保持させる連結部１３ａ４をばね部材１３ａに備えるとともに、連結部１３ａ４が、ばね部材１３ａからの突起体１３ｂの脱落を防ぐ抜け止め部材を形成することから、また、ばね部材１３ａと突起体１３ｂとの間に隙間を形成してあることから、第１実施形態に係るスイッチ用反転ばね６と同様の作用効果を得ることができる。なお、この第３実施形態に係るスイッチ用反転ばね１３の突起体１３ｂの大きさを、第１実施形態に係るスイッチ用反転ばね６の突起体６ｂに比べて小さくしてあることから、この第３実施形態に係るスイッチ用反転ばね１３を反転させる押圧力、すなわちスイッチ用反転ばね１３の作動力を、第１実施形態に係るスイッチ用反転ばね６の作動力に比べて小さくすることができる。   Similarly to the switch reversing spring 6 according to the first embodiment, the switch reversing spring 13 according to the third embodiment also includes a connecting portion 13a4 that integrally connects and holds the protrusion 13b to the spring member 13a. Since the connecting portion 13a4 forms a retaining member that prevents the protrusion 13b from falling off the spring member 13a, a gap is formed between the spring member 13a and the protrusion 13b. Therefore, the same effect as the switch reversing spring 6 according to the first embodiment can be obtained. The size of the protrusion 13b of the switch reversing spring 13 according to the third embodiment is smaller than that of the protrusion 6b of the switch reversing spring 6 according to the first embodiment. The pressing force for reversing the switch reversing spring 13 according to the third embodiment, that is, the operating force of the switch reversing spring 13 can be made smaller than the operating force of the switch reversing spring 6 according to the first embodiment.

［スイッチ用反転ばねの第４実施形態］
図８は本発明に係るスイッチ用反転ばねの第４実施形態を示す図で、（ａ）図は平面図、（ｂ）図は（ａ）図のＤ−Ｄ線に沿って切断した側断面図、（ｃ）図は裏面図である。 [Fourth Embodiment of Reversing Spring for Switch]
8A and 8B show a fourth embodiment of the switch reversal spring according to the present invention, in which FIG. 8A is a plan view, and FIG. 8B is a sectional side view taken along line DD in FIG. The figure and (c) figure are back views.

この図８に示すスイッチ用反転ばねの第４実施形態を構成するスイッチ用反転ばね１４も、上述した第１実施形態におけるスイッチ用反転ばね６と同様に、例えば可動接点から成り、ドーム状に膨出した導電性金属板から成るばね部材１４ａと、このばね部材１４ａに外部からの押圧力を伝達する圧伝達部材、すなわち突起体１４ｂを備えている。この突起体１４ｂは、例えば合成樹脂より成り、上方に向かうに従って径寸法が次第に小さくなり、縦断面が台形を呈する切断された円錐形状から成っている。ばね部材１４ａは、押圧力を受けると反転し、押圧力が解かれることにより自己復元可能となっている。   The switch reversing spring 14 constituting the fourth embodiment of the switch reversing spring shown in FIG. 8 is also composed of a movable contact, for example, like the switch reversing spring 6 in the first embodiment described above, and swells like a dome. A spring member 14a made of a conductive metal plate is provided, and a pressure transmission member for transmitting a pressing force from the outside to the spring member 14a, that is, a protrusion 14b. The projecting body 14b is made of, for example, a synthetic resin, and has a cut cone shape whose diameter is gradually reduced toward the upper side and whose longitudinal section has a trapezoidal shape. The spring member 14a reverses when it receives a pressing force, and can self-recover by releasing the pressing force.

このばね部材１４ａは、頂部部分の下面側に固定接点に接離する接点部、例えば３つの接点部１４ａ１，１４ａ２，１４ａ３をそれぞれ有するとともに、図８の（ａ）（ｃ）図に示すように、平面視で３つの接点部１４ａ１，１４ａ２，１４ａ３にほぼ囲まれる領域内に配置され、当該ばね部材１４ａと突起体１４ｂとを一体的に連結保持する連結部１４ａ４を有している。この連結部１４ａ４は、突起体１４ｂに与えられる押圧力の方向と交差する方向に起立させるように、ばね部材１４ａの一部を、例えばバーリング加工によって先細に形成してある。すなわち、この連結部１４ａ４を同図８の（ｂ）図に示すように、縦断面が、押圧方向に対して傾斜する形状となる中空管状に形成してある。連結部１４ａ４の外周面と、突起体１４ｂの外周面とが連続的な面を形成するように、これらの連結部１４ａ４と突起体１４ｂとを形成してある。このように先細バーリングに形成した連結部１４ａ４は、ばね部材１４ａからの突起体１４ｂの抜け止め部材を形成している。接点部１４ａ１，１４ａ２，１４ａ３のそれぞれは、下方に向かうに従って次第に先細となる例えば半球に近似した形状に形成してある。また、この連結部１４ａ４は、突起体１４ｂ内にインサート成形によって埋め込まれている。   The spring member 14a has contact portions, for example, three contact portions 14a1, 14a2, and 14a3 that contact and separate from the fixed contact on the lower surface side of the top portion, respectively, and as shown in FIGS. 8 (a) and 8 (c). The connecting portion 14a4 is disposed in a region substantially surrounded by the three contact portions 14a1, 14a2, and 14a3 in a plan view, and integrally connects and holds the spring member 14a and the protrusion 14b. A part of the spring member 14a is tapered by, for example, burring so that the connecting portion 14a4 stands up in a direction crossing the direction of the pressing force applied to the protrusion 14b. That is, as shown in FIG. 8B, the connecting portion 14a4 is formed in a hollow tubular shape whose longitudinal section is inclined with respect to the pressing direction. The connecting portion 14a4 and the protrusion 14b are formed so that the outer peripheral surface of the connecting portion 14a4 and the outer peripheral surface of the protrusion 14b form a continuous surface. Thus, the connection part 14a4 formed in the tapered burring forms a retaining member for the protrusion 14b from the spring member 14a. Each of the contact portions 14a1, 14a2, and 14a3 is formed in a shape that approximates, for example, a hemisphere that gradually tapers as it goes downward. Further, the connecting portion 14a4 is embedded in the protrusion 14b by insert molding.

この第４実施形態に係るスイッチ用反転ばね１４の突起体１４ｂの大きさは、上述した第３実施形態に係るスイッチ用反転ばね１３の突起体１３ｂに比べてさらに小さく形成してある。この第４実施形態に係るスイッチ用反転ばね１４は、スイッチ用反転ばね１４の反転動作時の押圧力、すなわち反転動作をさせるスイッチ用反転ばね１４の作動力が、ばね部材１４ａの連結部１４ａ４の根元の径寸法等に依存している。   The size of the protrusion 14b of the switch reversing spring 14 according to the fourth embodiment is smaller than that of the protrusion 13b of the switch reversing spring 13 according to the third embodiment described above. In the switch reversing spring 14 according to the fourth embodiment, the pressing force during the reversing operation of the switch reversing spring 14, that is, the operating force of the switch reversing spring 14 that causes the reversing operation, is applied to the connecting portion 14 a 4 of the spring member 14 a. It depends on the diameter of the root.

このように構成される第４実施形態に係るスイッチ用反転ばね１４も、上述した図１に示す中央固定接点３及び周辺固定接点４が形成されたスイッチ基板２を備えたスイッチ装置の可動接点として設けることができる。また、図４，５に示した製造方法の一実施形態によって製造することもできる。   The switch reversing spring 14 according to the fourth embodiment configured as described above is also used as a movable contact of the switch device including the switch substrate 2 on which the central fixed contact 3 and the peripheral fixed contact 4 shown in FIG. 1 are formed. Can be provided. Moreover, it can also manufacture by one Embodiment of the manufacturing method shown to FIG.

この第４実施形態に係るスイッチ用反転ばね１４も、第１実施形態に係るスイッチ用反転ばね６と同様に、突起体１４ｂをばね部材１４ａに一体的に連結保持させる連結部１４ａ４をばね部材１４ａに備えるとともに、ばね部材１４ａが突起体１４ｂの抜け止め部材を形成する連結部１４ａ４を備えていることから、突起体１４ｂとばね部材１４ａとの間の密着性を高め、突起体１４ｂをばね部材１４ａの上に強い保持力で保持させることができる。なお、この第４実施形態に係るスイッチ用反転ばね１４の突起体１４ｂの大きさを、第３実施形態に係るスイッチ用反転ばね１３の突起体１３ｂに比べて小さくしてあり、ばね部材１４ａの反転動作時に、突起体１４ｂの下端部がばね部材１４ｂに接触することがなく、ばね部材１４ａの反転動作が連結部１４ａ４の根元の径寸法等に依存することから、この第４実施形態に係るスイッチ用反転ばね１４を反転させる押圧力、すなわちスイッチ用反転ばね１４の作動力を、第３実施形態に係るスイッチ用反転ばね６の作動力よりもさらに小さくすることができる。   Similarly to the switch reversing spring 6 according to the first embodiment, the switch reversing spring 14 according to the fourth embodiment also includes a connecting portion 14a4 that integrally connects and holds the protrusion 14b to the spring member 14a. Since the spring member 14a includes a connecting portion 14a4 that forms a retaining member for the protrusion 14b, the adhesion between the protrusion 14b and the spring member 14a is improved, and the protrusion 14b is made a spring member. 14a can be held with a strong holding force. The size of the protrusion 14b of the switch reversing spring 14 according to the fourth embodiment is smaller than that of the protrusion 13b of the switch reversing spring 13 according to the third embodiment. During the reversing operation, the lower end portion of the protrusion 14b does not come into contact with the spring member 14b, and the reversing operation of the spring member 14a depends on the diameter of the base of the connecting portion 14a4. The pressing force for reversing the switch reversing spring 14, that is, the operating force of the switch reversing spring 14 can be made smaller than the operating force of the switch reversing spring 6 according to the third embodiment.

［スイッチ用反転ばねの第５実施形態］
図９は本発明に係るスイッチ用反転ばねの第５実施形態を示す図で、（ａ）図は平面図、（ｂ）図は（ａ）図のＥ−Ｅ線に沿って切断した側断面図、（ｃ）図は裏面図である。 [Fifth Embodiment of Reversing Spring for Switch]
FIGS. 9A and 9B are views showing a fifth embodiment of the switch reversing spring according to the present invention. FIG. 9A is a plan view, and FIG. The figure and (c) figure are back views.

この図９に示すスイッチ用反転ばねの第５実施形態であるスイッチ用反転ばね１５も、上述した第１実施形態に係るスイッチ用反転ばね６と同様に、例えば可動接点から成り、ドーム状に膨出した導電性金属板から成るばね部材１５ａと、このばね部材１５ａに外部からの押圧力を伝達する圧伝達部材、すなわち突起体１５ｂを備えている。この突起体１５ｂは、例えば合成樹脂より成り、上方に向かうに従って径寸法が次第に小さくなる縦断面が台形を頭部が切断された円錐形状から成っている。ばね部材１５ａは、押圧力を受けると反転し、押圧力が解かれることにより自己復元可能となっている。   The switch reversing spring 15 which is the fifth embodiment of the switch reversing spring shown in FIG. 9 is also composed of, for example, a movable contact and swells like a dome, like the switch reversing spring 6 according to the first embodiment described above. A spring member 15a made of a conductive metal plate is provided, and a pressure transmission member for transmitting a pressing force from the outside to the spring member 15a, that is, a protrusion 15b. The protrusion 15b is made of, for example, a synthetic resin, and has a conical shape in which a longitudinal section whose diameter dimension gradually decreases toward the upper side is trapezoidal and a head is cut. The spring member 15a reverses when it receives a pressing force, and can self-restore when the pressing force is released.

このばね部材１５ａは、頂部部分の下面側に固定接点に接離する接点部、例えば３つの接点部１５ａ１，１５ａ２，１５ａ３をそれぞれ有するとともに、図９の（ａ）（ｃ）図に示すように、平面視で３つの接点部６ａ１，６ａ２，６ａ３にほぼ囲まれる領域内に配置され、当該ばね部材１５ａと突起体１５ｂとを一体的に連結保持する連結部１５ａ４を有している。この連結部１５ａ４は、突起体１５ｂに与えられる押圧力の方向と交差する方向に上方に向けて起立させるように、ばね部材１５ａの一部を、先細バーリングに形成してある。すなわち、この連結部１５ａ４を同図９の（ｂ）図に示すように、縦断面が、押圧方向に対して傾斜する形状の中空管状に形成してある。接点部１５ａ１，１５ａ２，１５ａ３のそれぞれは、下方に向かうに従って次第に先細となる例えば半球に近似した形状に形成してある。また、連結部１５ａ４及び突起体１５ｂの径方向にあっては、連結部１５ａ４内に突起体１５ｂが位置するように、突起体１５ｂを連結部１５ａ４に埋め込み形成してある。   The spring member 15a has contact portions, for example, three contact portions 15a1, 15a2, and 15a3 that contact and separate from the fixed contact on the lower surface side of the top portion, respectively, and as shown in FIGS. 9A and 9C. The connecting portion 15a4 is disposed in a region substantially surrounded by the three contact portions 6a1, 6a2, and 6a3 in a plan view, and integrally connects and holds the spring member 15a and the protrusion 15b. A part of the spring member 15a is formed in a tapered burring so that the connecting portion 15a4 rises upward in a direction crossing the direction of the pressing force applied to the protrusion 15b. That is, as shown in FIG. 9B, the connecting portion 15a4 is formed in a hollow tubular shape whose longitudinal section is inclined with respect to the pressing direction. Each of the contact portions 15a1, 15a2, and 15a3 is formed in a shape that approximates, for example, a hemisphere that gradually tapers as it goes downward. Further, in the radial direction of the connecting portion 15a4 and the protrusion 15b, the protrusion 15b is embedded in the connecting portion 15a4 so that the protrusion 15b is positioned in the connecting portion 15a4.

この第５実施形態に係るスイッチ用反転ばね１５の突起体１５ｂの大きさを、上述した第４実施形態に係るスイッチ用反転ばね１４の突起体１４ｂに比べてさらに小さく形成してある。この第４実施形態も、スイッチ用反転ばね１５の反転動作時の押圧力、すなわち反転動作をさせるスイッチ用反転ばね１５の作動力が、ばね部材１５ａの連結部１５ａ４の根元の径寸法等に依存している。   The size of the protrusion 15b of the switch reversing spring 15 according to the fifth embodiment is smaller than that of the protrusion 14b of the switch reversing spring 14 according to the fourth embodiment described above. In the fourth embodiment as well, the pressing force during the reversing operation of the switch reversing spring 15, that is, the operating force of the switching reversing spring 15 for reversing the operation depends on the diameter of the base of the connecting portion 15a4 of the spring member 15a. is doing.

このように構成される第５実施形態に係るスイッチ用反転ばね１５も、上述した図１に示す中央固定接点３及び周辺固定接点４が形成されたスイッチ基板２を備えたスイッチ装置の可動接点として設けることができる。また、図４，５に示した製造方法の一実施形態によって製造することもできる。   The switch reversing spring 15 according to the fifth embodiment configured as described above is also used as a movable contact of the switch device including the switch substrate 2 on which the central fixed contact 3 and the peripheral fixed contact 4 shown in FIG. 1 are formed.
