Description
本発明は、プッシュスイッチに関し、特に、基板取り付け後に前方側からの押圧操作に対する耐性のある横押しタイプのプッシュスイッチに関するものである。 The present invention relates to a push switch, and more particularly to a lateral push type push switch that is resistant to a pressing operation from the front side after mounting a substrate.
昨今、携帯型の電子機器においては薄型の製品が増えている。このような薄型の携帯機器の側面に配置されるプッシュスイッチには横押しタイプのプッシュスイッチが用いられることが多い。 Nowadays, thin products are increasing in portable electronic devices. As a push switch arranged on the side surface of such a thin portable device, a lateral push type push switch is often used.
このようなプッシュスイッチとしては、下記の特許文献1に記載のプッシュスイッチが知られている。 As such a push switch, a push switch described in Patent Document 1 below is known.
以下、図32を用いて、特許文献1に記載のプッシュスイッチ900について説明する。図32は特許文献1に記載のプッシュスイッチ900の構成を示す断面図である。 Hereinafter, the push switch 900 described in Patent Document 1 will be described with reference to FIG. FIG. 32 is a cross-sectional view showing a configuration of a push switch 900 described in Patent Document 1.
特許文献1に記載のプッシュスイッチ900は、中央電極およびサイド電極を備えたケース927、導電性金属板の接触片930、防塵シート931、キートップ932、金属カバー933からなる押釦スイッチである。キートップ932は、突出して形成され、操作者により押圧操作されるキー釦部940を有している。金属カバー933は、キー釦部940を挿通可能なキー釦貫通孔946を有する前面部942、上方側を覆う天板部943、前面部942の下端部を後方に折曲形成しプリント基板926の前方固定ランド951に固定される底板部、前面部942の両側部の側板部945、側板部945を後方に延長した折込片958からなる。プッシュスイッチ900は、前面部942、天板部943、底板部944、側板部945で構成される空間に、キートップ932を移動可能に遊嵌し、かつ、防塵シート931とケース927を天板部943と底板部944の後端面に密接した後、折込片958をケース927の後面側に折曲して、折込片958の先端部同士を対向させて包み込むように固定し、折込片958の先端部をプリント基板926の後方固定ランド953に固定している。 A push switch 900 described in Patent Document 1 is a push button switch including a case 927 having a central electrode and a side electrode, a conductive metal plate contact piece 930, a dustproof sheet 931, a key top 932, and a metal cover 933. The key top 932 has a key button portion 940 that is formed so as to protrude and is pressed by an operator. The metal cover 933 has a front surface portion 942 having a key button through-hole 946 through which the key button portion 940 can be inserted, a top plate portion 943 covering the upper side, and a lower end portion of the front surface portion 942 bent backward to form a printed board 926. A bottom plate portion fixed to the front fixed land 951, side plate portions 945 on both sides of the front surface portion 942, and a folded piece 958 extending the side plate portion 945 rearward. In the push switch 900, a key top 932 is movably fitted in a space formed by a front surface portion 942, a top plate portion 943, a bottom plate portion 944, and a side plate portion 945, and the dustproof sheet 931 and the case 927 are attached to the top plate. After the portion 943 and the bottom plate portion 944 are in close contact with the rear end surface, the folding piece 958 is bent to the rear surface side of the case 927 and fixed so as to wrap the tip portions of the folding piece 958 facing each other. The front end is fixed to the rear fixed land 953 of the printed circuit board 926.
プッシュスイッチ900は、キートップ932を押圧した方向に、折込片958の先端部同士が対向して状態で、折込片958の先端部の下側がプリント基板926の後方固定ランド953に半田付けで固定されている。そのため、強めの力でキートップ932が押圧されたとしても、折込片958が広がって固定が緩むことは無い。しかしながら、昨今、携帯型の電子機器においては多機能化などに伴い、限られたスペースにより多くの電子部品を実装する為に、より小型のプッシュスイッチが求められている。特許文献1に記載のプッシュスイッチ900と同じ構造で小型化した場合、金属カバー933の板厚が薄くなったり、半田付け可能な面積が小さくなったりする。そのため、小型化する前には問題の無かったレベルの強めの力でキートップ932が押圧された場合に、半田付けが外れないまでも、後方固定ランド953に半田付けがされていない折込片958の先端部の上側が広がり、ケース927に対する金属カバー933の保持が弱まることが懸念される。仮に、このようにケース927に対する金属カバー933の保持が弱まると、操作はできるが接触片930を介した中央電極とサイド電極との接離のタイミングがずれたり、操作感触が悪くなったりするなどの不具合が発生する。 The push switch 900 is fixed by soldering to the rear fixed land 953 of the printed circuit board 926 with the lower ends of the folded pieces 958 facing each other in the direction in which the key top 932 is pressed. Has been. Therefore, even if the key top 932 is pressed with a strong force, the folding piece 958 does not spread and the fixing is not loosened. However, in recent years, with the increase in functionality in portable electronic devices, a smaller push switch is required in order to mount more electronic components in a limited space. In the case of downsizing with the same structure as the push switch 900 described in Patent Document 1, the thickness of the metal cover 933 is reduced, and the solderable area is reduced. Therefore, when the key top 932 is pressed with a strong force of a level that had no problem before downsizing, the folded piece 958 that is not soldered to the rear fixed land 953 until the soldering is not removed. There is a concern that the upper side of the front end of the metal plate spreads and the holding of the metal cover 933 on the case 927 is weakened. If the holding of the metal cover 933 with respect to the case 927 is weakened in this way, the operation can be performed, but the contact / separation timing of the center electrode and the side electrode via the contact piece 930 is shifted, or the operation feeling is deteriorated. The problem occurs.

It was set as the structure integrated by engaging. Thereby, since the part where the rear cover member was pressed and expanded is not spread, the pushing strength from the front side can be improved as compared with the prior art. Therefore, there is an effect that it is possible to provide a lateral push type push switch that is resistant to a pressing operation from the front side after the substrate is attached.
請求項2の発明によれば、係合部を切り欠きからなる係合凹部とすることで、係合部を簡易に構成することができる。また、後方カバー部材の腕部が係合凹部の上下の内壁に当接するように係合する構成とすることで、前方カバー部材と後方カバー部材とを十分な保持力で係合することができる。したがって、簡易な構成で、前方カバー部材と後方カバー部材とを十分な保持力で係合することができる、という効果を奏する。 According to invention of Claim 2, an engaging part can be comprised simply by making an engaging part into the engaging recessed part which consists of notches. In addition, the front cover member and the rear cover member can be engaged with each other with a sufficient holding force by adopting a configuration in which the arms of the rear cover member are engaged so as to contact the upper and lower inner walls of the engagement recess. . Therefore, the front cover member and the rear cover member can be engaged with each other with a sufficient holding force with a simple configuration.
請求項3の発明によれば、係合凹部の上下方向で対向する面部同士の間隔が、幅方向外方側に向うにしたがって狭くなるように形成され、先端が上下方向に2股に分割された係合端部が係合凹部に挿入され、係合端部を係合凹部の上下方向で対向する面部と当接するように押し広げて、前方カバー部材と後方カバー部材とが係合される構成とした。係合端部を上下方向に押し広げて、前方カバー部材と後方カバー部材と係合させると、係合凹部の上下方向で対向する面部同士の間隔が広い側の係合端部は、係合凹部の上下方向で対向する面部同士の間隔が狭い側の係合端部よりも広くなるように広げられる。これにより、係合端部はそれぞれ捻じられた様にひろげられ、係合端部と係合凹部との係合はより強固となり、押圧方向には外れにくくなる。また、係合凹部の上下方向で対向する面部同士の間隔が、幅方向外方側に向うにしたがって狭くなるように形成されているため、幅方向外方側に対しても係合は外れにくくなっている。したがって、基板取り付け後に前方側からの押圧操作に対してより耐性のある横押しタイプのプッシュスイッチを提供することができる、という効果を奏する。 According to the invention of claim 3, the interval between the surface portions facing each other in the vertical direction of the engaging concave portion is formed so as to become narrower toward the outer side in the width direction, and the tip is divided into two forks in the vertical direction. The engagement end portion is inserted into the engagement recess, and the engagement end is expanded so as to come into contact with the surface portion facing the vertical direction of the engagement recess, so that the front cover member and the rear cover member are engaged. The configuration. When the engagement end portion is pushed up and down and engaged with the front cover member and the rear cover member, the engagement end portion on the side where the surface portions facing each other in the vertical direction of the engagement recess are wide is engaged. It is expanded so that the space | interval of the surface parts facing in the up-down direction of a recessed part may become wider than the engagement edge part of the narrow side. As a result, the engagement end portions are spread as if they were twisted, and the engagement between the engagement end portion and the engagement concave portion becomes stronger, and it is difficult to disengage in the pressing direction. In addition, since the interval between the surface portions facing each other in the vertical direction of the engagement concave portion is formed so as to narrow toward the outer side in the width direction, the engagement is not easily released even on the outer side in the width direction. It has become. Therefore, it is possible to provide a lateral push type push switch that is more resistant to a pressing operation from the front side after the board is attached.
請求項4の発明によれば、係合部を貫通孔からなる係合穴部とすることで、係合部を簡易に構成することができる。また、後方カバー部材の腕部が係合穴部に挿入され、折り曲げることで係合する構成とすることで、前方カバー部材と後方カバー部材とを十分な保持力で係合することができる。したがって、簡易な構成で、前方カバー部材と後方カバー部材とを十分な保持力で係合することができる、という効果を奏する。 According to invention of Claim 4, an engaging part can be comprised simply by making an engaging part into the engaging hole part which consists of a through-hole. In addition, the front cover member and the rear cover member can be engaged with each other with a sufficient holding force by adopting a configuration in which the arm portion of the rear cover member is inserted into the engagement hole portion and bent. Therefore, the front cover member and the rear cover member can be engaged with each other with a sufficient holding force with a simple configuration.
請求項5の発明によれば、係合穴部の開口形状を、幅方向における外方側が円弧形状とすることで、幅方向における外方側においては上下方向の寸法が内方側よりも小さくなるので、係合穴部と腕部とを係合するときに、腕部が係合穴部の幅方向における外方側の面に接触すると、腕部は内方側へ寄せられる。したがって、前方カバー部材と後方カバー部材とをガタのない状態で固定することができ、外れにくい強固な係合とすることができる、という効果を奏する。 According to the fifth aspect of the present invention, the opening shape of the engagement hole portion is an arc shape on the outer side in the width direction, so that the vertical dimension is smaller on the outer side in the width direction than on the inner side. Therefore, when the engagement hole and the arm are engaged with each other, if the arm contacts the outer surface in the width direction of the engagement hole, the arm is moved inward. Therefore, there is an effect that the front cover member and the rear cover member can be fixed without any backlash, and a strong engagement that is difficult to come off can be obtained.
請求項6の発明によれば、第1半田付け部と第2半田付け部とを設けるとともに、第1半田付け部と第2半田付け部とが僅かな隙間を有して隣り合って配置されることで、第1半田付け部と第2半田付け部とを半田付けした際に、前方カバー部材と後方カバー部材とは半田により連結される。そのため、操作部材を強い力で押圧された場合にも、係合端部と係合凹部との係合箇所にかかる負荷が半田により連結された部分に分散されるため、係合端部と係合凹部との係合は外れにくくなる。したがって、基板取り付け後に前方側からの押圧操作に対してさらに耐性のある横押しタイプのプッシュスイッチを提供することができる、という効果を奏する。 According to the invention of claim 6, the first soldering portion and the second soldering portion are provided, and the first soldering portion and the second soldering portion are arranged adjacent to each other with a slight gap. Thus, when the first soldering portion and the second soldering portion are soldered, the front cover member and the rear cover member are connected by solder. For this reason, even when the operation member is pressed with a strong force, the load applied to the engagement portion between the engagement end portion and the engagement recess portion is distributed to the portion connected by the solder. Engagement with the joint recess is difficult to disengage. Therefore, it is possible to provide a lateral push type push switch that is more resistant to a pressing operation from the front side after the board is attached.
請求項7の発明によれば、第1逃げ部および第2逃げ部を設けることで、プッシュスイッチを基板に半田付けする際に発生するフラックスが、第1逃げ部および第2逃げ部を伝わるため、フラックスがケースの空間部に到達するまでの距離を長くしたり、フラックスを空間部とは異なる方向へ誘導することができる。よって、空間部内にフラックスが入り込みにくくなり、フラックスの付着による可動接点部材と固定接点部との導通不良の発生を少なくすることができる。したがって、安定したスイッチングができるプッシュスイッチを提供することができる、という効果を奏する。 According to the seventh aspect of the present invention, since the first relief portion and the second relief portion are provided, the flux generated when the push switch is soldered to the substrate is transmitted through the first relief portion and the second relief portion. The distance until the flux reaches the space of the case can be increased, or the flux can be guided in a direction different from the space. Therefore, it becomes difficult for flux to enter the space portion, and occurrence of poor conduction between the movable contact member and the fixed contact portion due to adhesion of the flux can be reduced. Therefore, it is possible to provide a push switch capable of stable switching.
以上より、本発明によれば、基板取り付け後に前方側からの押圧操作に対する耐性のある横押しタイプのプッシュスイッチを提供することができる。 As described above, according to the present invention, it is possible to provide a lateral push type push switch that is resistant to a pressing operation from the front side after the substrate is attached.

The sheet member 6 is held by the second case member 3f by the adhesive force of the adhesive surface 6a, and holds the movable contact member 2 in the second space 3m. Since the sheet member 6 has flexibility, when the sheet member 6 is pressed through the sheet member 6, the movable contact portion 2a of the movable contact member 2 is movably held in the second space 3m. . The operating member 1 is held in the first space portion 3k of the first case member 3e in a state where the button portion 1a is inserted through the opening 3g from the first space portion 3k side. The first case member 3e holding the operation member 1 in the first space 3k sandwiches the sheet member 6 with the second case member 3f with the actuator portion 1c of the operation member 1 facing the sheet member 6, and second The 1 space part 3k and the 2nd space part 3m engage so that the space part 3b may be formed. By engaging the first case member 3e and the second case member 3f in this way, the actuator portion 1c of the operation member 1 and the movable contact portion 2a of the movable contact member 2 are in contact via the sheet member 6. Further, the front cover member 4 allows the button portion 1a of the operation member 1 to be inserted into the through hole 4a, and allows the positioning convex portion 3h of the first case member 3e to be inserted into the positioning hole portion 4e (see FIG. 10).

The rear cover member 5 covers the rear side of the case 3 (second case member 3f) with the base portion 5a, and engages with the second case member 3f with the arm portion 5b extending forward. . Further, the arm portion 5b extending forward is engaged with the engagement portion 4A (engagement recess 4b) of the front cover member 4, and the front cover member 4 and the rear cover member 5 are integrated. The engaging end portion 5c is inserted into the engaging recess 4b which is the engaging portion 4A, and as shown in FIG. 3B, the engaging end 5c contacts the surface portion 4c which is the inner wall facing the engaging recess 4b in the vertical direction. It is spread and engaged so that it touches. In this way, the engagement end portion 5c is spread and contacted with the engagement recess 4b, whereby the front cover member 4 and the rear cover member 5 are integrated. In addition, the engagement end portion 5c is expanded and brought into contact with the engagement recess 4b, whereby the first case member 3e and the second case member 3f press-clamp the sheet member 6. In this way, the push switch 100 in the first embodiment is configured.

次にプッシュスイッチ100の動作について図11および図12を用いて説明する。図12は図11に示す状態から押圧操作された後の状態を示す模式断面図である。 Next, the operation of the push switch 100 will be described with reference to FIGS. 11 and 12. 12 is a schematic cross-sectional view showing a state after a pressing operation is performed from the state shown in FIG.
図11に示す状態は、プッシュスイッチ100が操作されていない初期状態を示している。図11に示す状態においては、常接接点部2cは第2固定接点部3pと接触しているが、可動接点部2aは第1固定接点部3nとは離間している。つまり、図11に示す状態は、第1固定接点部3nと第2固定接点部3pとの電気的な導通は無い状態である。図11に示す状態から、図12に示すように、操作部材1を後方側(X2方向)へ押圧すると、シート部材6を介して可動接点部2aに接触するアクチュエータ部1cは可動接点部2aを後方側へ押圧する。押圧された可動接点部2aは後方側へ撓んだ後に反転し、第1固定接点部3nに接触する。可動接点部2aと第1固定接点部3nとが接触することで、第1固定接点部3nと第2固定接点部3pとは、可動接点部材2を介して電気的に導通される。また、操作部材1への押圧を解除すると、可動接点部2aの弾性力により、図11に示す初期状態に復帰し、第1固定接点部3nと第2固定接点部3pとの電気的な導通は無い状態となる。このように、第1固定接点部3nと第2固定接点部3pとの電気的な導通状態を切り替えることで入力を行なうことができ、プッシュスイッチとして機能する。 The state shown in FIG. 11 shows an initial state where the push switch 100 is not operated. In the state shown in FIG. 11, the normal contact portion 2 c is in contact with the second fixed contact portion 3 p, but the movable contact portion 2 a is separated from the first fixed contact portion 3 n. That is, the state shown in FIG. 11 is a state where there is no electrical continuity between the first fixed contact portion 3n and the second fixed contact portion 3p. When the operation member 1 is pressed backward (X2 direction) from the state shown in FIG. 11, the actuator portion 1 c that contacts the movable contact portion 2 a via the sheet member 6 moves the movable contact portion 2 a. Press backwards. The pressed movable contact portion 2a bends backward and then reverses to contact the first fixed contact portion 3n. When the movable contact portion 2a and the first fixed contact portion 3n come into contact with each other, the first fixed contact portion 3n and the second fixed contact portion 3p are electrically connected via the movable contact member 2. Further, when the pressing on the operation member 1 is released, the initial state shown in FIG. 11 is restored by the elastic force of the movable contact portion 2a, and electrical conduction between the first fixed contact portion 3n and the second fixed contact portion 3p. There will be no state. Thus, an input can be performed by switching the electrical continuity between the first fixed contact portion 3n and the second fixed contact portion 3p, and the device functions as a push switch.
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。なお、図13は第1実施形態における係合凹部4bと係合端部5cとの係合状態を示す模式図である。 Hereinafter, the effect by having set it as this embodiment is demonstrated. FIG. 13 is a schematic diagram showing an engagement state between the engagement recess 4b and the engagement end 5c in the first embodiment.
本実施形態のプッシュスイッチ100では、操作部材1と、可動接点部材2と、固定接点部3aを有し、操作部材1および可動接点部材2を収容可能で前方側が開放された空間部3bを備えるケース3と、空間部3bを覆う前方カバー部材4と、ケース3の後方側を覆う基部5aと、基部5aの両端から前方側にそれぞれ延出している腕部5bとを備える後方カバー部材5と、を有するプッシュスイッチにおいて、前方カバー部材4には、操作部材1が突出する貫通穴4aと、両端側に後方カバー部材5の腕部5bと係合される係合部4Aとが設けられており、前方カバー部材4の係合部4Aに後方カバー部材5の腕部5bがそれぞれ係合されて前方カバー部材4と後方カバー部材5とが一体化されている、構成とした。 The push switch 100 according to this embodiment includes an operation member 1, a movable contact member 2, and a fixed contact portion 3a, and includes a space portion 3b that can accommodate the operation member 1 and the movable contact member 2 and that is open on the front side. A rear cover member 5 including a case 3, a front cover member 4 covering the space portion 3b, a base portion 5a covering the rear side of the case 3, and arm portions 5b extending from both ends of the base portion 5a to the front side, respectively In the push switch having the above, the front cover member 4 is provided with a through hole 4a from which the operation member 1 protrudes, and an engagement portion 4A to be engaged with the arm portion 5b of the rear cover member 5 at both ends.

To be integrated with each other. Thereby, since the part where the rear cover member 5 was pressed and spread does not spread, the pushing strength from the front side can be improved as compared with the prior art. Therefore, there is an effect that it is possible to provide a lateral push type push switch that is resistant to a pressing operation from the front side after the substrate is attached.

The arm 5b of the rear cover member 5 is engaged with the engagement recess 4b of the front cover member 4 so that the front cover member 4 and the rear cover member 5 are integrated.
Further, in the push switch 100 of the present embodiment, the engaging portion 4A is the engaging recess 4b formed by a notch, and the arm portion 5b of the rear cover member 5 is engaged with the upper and lower inner walls of the engaging recess 4b. The configuration is matched.
これにより、後方側カバー部材の基部5aがケース3の後方側を覆う、すなわちケース3の後方側には後方側カバー部材が分断された箇所が無いとともに、2つの腕部5bを前方側カバー部材と係合させて一体化させる構成とした。これにより、押圧されて後方側カバー部材の分断された箇所が広がることはないので、先行技術に比べて前方側からの押し込み強度を向上させることができる。よって、基板取り付け後に前方側からの押圧操作に対する耐性のある横押しタイプのプッシュスイッチを提供することができる、という効果を奏する。
これにより、係合部4Aを切り欠きからなる係合凹部4bとすることで、係合部4Aを簡易に構成することができる。また、後方カバー部材5の腕部5bが係合凹部4bの上下の内壁に当接するように係合する構成とすることで、前方カバー部材4と後方カバー部材5とを十分な保持力で係合することができる。したがって、簡易な構成で、前方カバー部材4と後方カバー部材5とを十分な保持力で係合することができる、という効果を奏する。
Accordingly, the base portion 5a of the rear cover member covers the rear side of the case 3, that is, there is no portion where the rear cover member is divided on the rear side of the case 3, and the two arm portions 5b are connected to the front cover member. To be integrated with each other. Thereby, since the part where the rear cover member is divided by being pressed does not spread, the pressing strength from the front side can be improved as compared with the prior art. Therefore, there is an effect that it is possible to provide a lateral push type push switch that is resistant to a pressing operation from the front side after the substrate is attached.
Thereby, 4 A of engaging parts can be simply comprised by making the engaging part 4A into the engaging recessed part 4b which consists of notches. In addition, the front cover member 4 and the rear cover member 5 are engaged with each other with a sufficient holding force by engaging the arm portion 5b of the rear cover member 5 so as to contact the upper and lower inner walls of the engagement recess 4b. Can be combined. Therefore, the front cover member 4 and the rear cover member 5 can be engaged with each other with a sufficient holding force with a simple configuration.
また、本実施形態のプッシュスイッチ100では、前方カバー部材4の係合凹部4bの上下方向で対向する面部4c同士の間隔は、幅方向外方側に向うにしたがって狭くなるように形成されており、後方カバー部材5の腕部5bは、先端が上下方向に2股に分割された係合端部5cとなっており、係合端部5cは係合凹部4bに挿入されて、係合凹部4bの上下方向で対向する面部4cと当接するように押し広げられて係合されている、構成とした。 Moreover, in the push switch 100 of this embodiment, the space | interval of the surface parts 4c which oppose the up-down direction of the engaging recessed part 4b of the front cover member 4 is formed so that it may become narrow toward the width direction outward side. The arm portion 5b of the rear cover member 5 is an engagement end portion 5c whose tip is divided into two forks in the vertical direction, and the engagement end portion 5c is inserted into the engagement recess portion 4b, It is configured to be expanded and engaged so as to come into contact with the surface portion 4c opposed in the vertical direction of 4b.
これにより、係合凹部4bの上下方向で対向する面部4c同士の間隔が、幅方向外方側に向うにしたがって狭くなるように形成され、先端が上下方向に2股に分割された係合端部5cが係合凹部4bに挿入され、係合端部5cを係合凹部4bの上下方向で対向する面部4cと当接するように押し広げて、前方カバー部材4と後方カバー部材5とが係合される構成とした。係合端部5cを上下方向に押し広げて、前方カバー部材4と後方カバー部材5と係合させると、係合凹部4bの上下方向で対向する面部4c同士の間隔が広い側の係合端部5cは、係合凹部4bの上下方向で対向する面部4c同士の間隔が狭い側の係合端部5cよりも広くなるように広げられる。これにより、図13に示すように係合端部5cは、それぞれ捻じられた様にひろげられ、係合端部5cと係合凹部4bとの係合はより強固となり、押圧方向には外れにくくなる。また、係合凹部4bの上下方向で対向する面部4c同士の間隔が、幅方向外方側に向うにしたがって狭くなるように形成されているため、幅方向外方側に対しても係合は外れにくくなっている。したがって、基板取り付け後に前方側からの押圧操作に対してより耐性のある横押しタイプのプッシュスイッチを提供することができる、という効果を奏する。 Thus, the engagement end is formed such that the interval between the surface portions 4c opposed to each other in the vertical direction of the engagement recess 4b becomes narrower toward the outer side in the width direction, and the tip is divided into two forks in the vertical direction. The portion 5c is inserted into the engagement recess 4b, and the engagement end portion 5c is expanded so as to contact the surface portion 4c opposed to the engagement recess 4b in the vertical direction, so that the front cover member 4 and the rear cover member 5 are engaged. The composition was combined. When the engagement end portion 5c is pushed up and down and engaged with the front cover member 4 and the rear cover member 5, the engagement end on the side where the interval between the surface portions 4c facing each other in the vertical direction of the engagement recess 4b is wide. The part 5c is widened so as to be wider than the engagement end part 5c on the side where the distance between the face parts 4c facing each other in the vertical direction of the engagement concave part 4b is narrow. As a result, as shown in FIG. 13, the engagement end portions 5c are expanded as if they were twisted, and the engagement between the engagement end portions 5c and the engagement recesses 4b becomes stronger and is less likely to come off in the pressing direction. Become. Moreover, since the space | interval of the surface parts 4c which oppose the up-down direction of the engagement recessed part 4b is formed so that it may become narrow as it goes to the width direction outer side, engagement is also performed to the width direction outer side. It is hard to come off. Therefore, it is possible to provide a lateral push type push switch that is more resistant to a pressing operation from the front side after the board is attached.
また、本実施形態のプッシュスイッチ100では、前方カバー部材4には、第1半田付け部4dが設けられ、後方カバー部材5には、第2半田付け部5dが設けられ、第1半田付け部4dと第2半田付け部5dとは、僅かな隙間Dを有して隣り合って配置されている、構成とした。 In the push switch 100 according to the present embodiment, the front cover member 4 is provided with a first soldering portion 4d, and the rear cover member 5 is provided with a second soldering portion 5d. 4d and the 2nd soldering part 5d were set as the structure arrange | positioned adjacent to each other with a slight gap D.
これにより、第1半田付け部4dと第2半田付け部5dとを設けるとともに、第1半田付け部4dと第2半田付け部5dとが僅かな隙間Dを有して隣り合って配置されることで、第1半田付け部4dと第2半田付け部5dとを半田付けした際に、前方カバー部材4と後方カバー部材5とは半田により連結される。そのため、操作部材1を強い力で押圧された場合にも、係合端部5cと係合凹部4bとの係合箇所にかかる負荷が半田により連結された部分に分散されるため、係合端部5cと係合凹部4bとの係合は外れにくくなる。したがって、基板取り付け後に前方側からの押圧操作に対してさらに耐性のある横押しタイプのプッシュスイッチを提供することができる、という効果を奏する。例えば、図3に記載の基板CB1にプッシュスイッチ100がマウントされると、第1半田付け部4dと第2半田付け部5dとは同じランドLN1上に配置される。このようなランドLN1上に第1半田付け部4dおよび第2半田付け部5dを半田付けすると、ランドLN1を伝わって半田が繋がり、前方カバー部材4と後方カバー部材5とは半田により連結される。 Thus, the first soldering part 4d and the second soldering part 5d are provided, and the first soldering part 4d and the second soldering part 5d are arranged adjacent to each other with a slight gap D. Thus, when the first soldering portion 4d and the second soldering portion 5d are soldered, the front cover member 4 and the rear cover member 5 are connected by solder. For this reason, even when the operation member 1 is pressed with a strong force, the load applied to the engagement portion between the engagement end portion 5c and the engagement recess portion 4b is distributed to the portion connected by the solder. The engagement between the portion 5c and the engagement recess 4b is difficult to disengage. Therefore, it is possible to provide a lateral push type push switch that is more resistant to a pressing operation from the front side after the board is attached. For example, when the push switch 100 is mounted on the substrate CB1 illustrated in FIG. 3, the first soldering portion 4d and the second soldering portion 5d are disposed on the same land LN1. When the first soldering portion 4d and the second soldering portion 5d are soldered on the land LN1, the solder is connected through the land LN1, and the front cover member 4 and the rear cover member 5 are connected by solder. .
また、本実施形態のプッシュスイッチ100では、ケース3の、第1半田付け部4dおよび第2半田付け部5dと対向する箇所には、凹形状に形成された第1逃げ部3cが設けられ、ケース3の下面には、幅方向に溝状に延設された第2逃げ部3dが設けられている、構成とした。 Further, in the push switch 100 of the present embodiment, the case 3 is provided with a first relief portion 3c formed in a concave shape at a location facing the first soldering portion 4d and the second soldering portion 5d, The lower surface of the case 3 is provided with a second relief portion 3d extending in a groove shape in the width direction.
これにより、第1逃げ部3cおよび第2逃げ部3dを設けることで、プッシュスイッチを基板に半田付けする際に発生するフラックスが、第1逃げ部3cおよび第2逃げ部3dを伝わるため、フラックスがケース3の空間部3bに到達するまでの距離を長くしたり、フラックスを空間部3bとは異なる方向へ誘導することができる。よって、空間部3b内にフラックスが入り込みにくくなり、フラックスの付着による可動接点部材2と固定接点部3aとの導通不良の発生を少なくすることができる。したがって、安定したスイッチングができるプッシュスイッチを提供することができる、という効果を奏する。 Thus, by providing the first escape portion 3c and the second escape portion 3d, the flux generated when the push switch is soldered to the substrate is transmitted to the first escape portion 3c and the second escape portion 3d. The distance until the space 3b reaches the space 3b of the case 3 can be increased, or the flux can be guided in a direction different from the space 3b. Therefore, it becomes difficult for flux to enter the space 3b, and the occurrence of poor conduction between the movable contact member 2 and the fixed contact 3a due to adhesion of the flux can be reduced. Therefore, it is possible to provide a push switch capable of stable switching.
また、第1逃げ部3cに対向する第1半田付け部4dおよび第2半田付け部5dの面には、半田付けした際にフィレットが形成されるため、第1半田付け部4dおよび第2半田付け部5dは両側にフィレットが形成され、プッシュスイッチ100は基板に対してより強固に保持される。 In addition, since fillets are formed on the surfaces of the first soldering portion 4d and the second soldering portion 5d facing the first relief portion 3c when soldering, the first soldering portion 4d and the second soldering portion are formed. The attaching part 5d is formed with fillets on both sides, and the push switch 100 is held more firmly against the substrate.
また、本実施形態のプッシュスイッチでは、ケース3の後方側に位置する、後方カバー部材5の基部5aから下方へ延出して第3半田付け部5fを有する構成とした。 Further, the push switch of the present embodiment is configured to have a third soldering portion 5f extending downward from the base portion 5a of the rear cover member 5 located on the rear side of the case 3.
これにより、例えば、図3に示す基板CB1のような基板にマウントした際に、第3半田付け部5fを対応するランドLN1に半田付けで固定することができる。第3半田付け部5fを半田付けすることで、押圧方向側を保持することになり、入力操作の際の押圧に対する耐性がより高くなる。基板取り付け後に前方側からの押圧操作に対してさらに耐性のある横押しタイプのプッシュスイッチを提供することができる、という効果を奏する。 Thereby, for example, when mounted on a substrate such as the substrate CB1 shown in FIG. 3, the third soldering portion 5f can be fixed to the corresponding land LN1 by soldering. By soldering the third soldering portion 5f, the pressing direction side is held, and the resistance to pressing during the input operation is further increased. There is an effect that it is possible to provide a lateral push type push switch that is more resistant to a pressing operation from the front side after the substrate is attached.
また、本実施形態のプッシュスイッチ100では、第1ケース部材3eと第2ケース部材3fとでシート部材6を挟み込む構成とした。 In the push switch 100 according to the present embodiment, the sheet member 6 is sandwiched between the first case member 3e and the second case member 3f.
これにより、粘着面6aの粘着力による保持に加えて、シート部材6がより安定して保持される。また、前方カバー部材4と後方カバー部材5とを係合する際にケース3に加わる力の一部を吸収し、ケース3の破損を防ぐことができるという効果を奏する。 Thereby, in addition to the holding | maintenance by the adhesive force of the adhesion surface 6a, the sheet | seat member 6 is hold | maintained more stably. In addition, when the front cover member 4 and the rear cover member 5 are engaged, a part of the force applied to the case 3 is absorbed, and the case 3 can be prevented from being damaged.

図28に示すように、可動接点部材22は第2ケース部材24の第2空間部24b内に収容される。可動接点部材22は可動接点部22aが前方(X1方向)へ突出する向きに配置され、一方(図23に示すZ2方向側)の常接接点部22cは第2空間部24bの最奥面24eに露出する第2固定接点部24gの接触部24h(図19参照)と接触し、他方の常接接点部22cは、最奥面24eの第1固定接点部24fを挟んで第2固定接点部24gに対向する位置に周辺接触部24qと同じ高さとなるように突出している箇所(図19参照)に接触している。なお、可動接点部22aは第1固定接点部24fとは離間している。シート部材29は、粘着面29aが第2空間部24bに対向する向きで、可動接点部材22が配置された第2空間部24bを覆うように配置される。シート部材29は粘着面29aの粘着力により第2ケース部材24の第2対向面24dに保持されるとともに、可動接点部材22を第2空間部24b内に保持して、可動接点部材22と第2固定接点部24gとは常時接触される。シート部材29は屈曲性を有しているため、シート部材29を介して押圧された場合には、可動接点部材22の可動接点部22aは第2空間部24b内でも可動可能で、かつ中央接触部24n(図19参照)と接触可能な位置に保持されている。操作部材21は、ボタン部21cを第1空間部25a側から開口部25eに挿通した状態で、第1ケース部材25の第1空間部25a内に保持される。なお、操作部材21は、その一部(突出部21a(図24参照))が突出形状部25d(図21参照)に配置されるとともに案内され、第1空間部25a内をスライド移動可能に保持されている。第1空間部25a内に操作部材21を保持した第1ケース部材25は、操作部材21のアクチュエータ部21bがシート部材29と対向する向きで、第2ケース部材24と係合する。すなわち、第1対向面25cと第2対向面24dとでシート部材29を挟み込み、第1空間部25aと第2空間部24bとが、操作部材21及び可動接点部材22を収容する空間部23aを形成するように係合する。このように第1ケース部材25と第2ケース部材24とを係合することで、操作部材21のアクチュエータ部21bと可動接点部材22の可動接点部22aとはシート部材29を介して接触する。また、前方カバー部材27は、操作部材21のボタン部21cが貫通穴27aから突出した状態で、空間部23aを覆うように第1ケース部材25と係合している。また、後方カバー部材28は、基部28aでケース23(第2ケース部材24)の後方側を覆うとともに、腕部28bを前方に延出させた状態で第2ケース部材24と係合している。また前方へ延出した腕部28bが、前方カバー部材27の係合部27bにそれぞれ係合されて前方カバー部材27と後方カバー部材28とが一体化され、カバー部材26が形成されている。なお、第2実施形態においては、係合部27bと腕部28bとの係合は、後方カバー部材28の腕部28bの先端部28cが、前方カバー部材27の係合穴部27cに挿入され、前方カバー部材27の前方側にて内方側に折り曲げられて係合することで行われている。このように、カバー部材26(図25参照)が形成されることで、第1ケース部材25と第2ケース部材24とは、シート部材29を圧接挟持する。このようにして第2実施形態におけるプッシュスイッチ200は構成される。プッシュスイッチ200が形成されると、図22に示すように、突出形状部25dの一部と第2対向面24dの一部とが対向するように配置されている。したがって、突出形状部25dに沿って移動可能に配置される操作部材21の突出部21aは、第2対向面24dに接触可能な位置に配置されている。ただし、操作部材21を介して可動接点部材22を押圧し、可動接点部22aを固定接点部24a(第1固定接点部24f)に接触させたときに、突出部21aは第2対向面24dから離間している。また、第2開口24cの外形形状の長手辺と短手辺とが交差する箇所が突出形状部25dに対応した箇所に配置されているため、操作部材21の突出部21aは、第2開口24cの外形形状の長手辺と短手辺とが交差する箇所で、第2対向面24dに接触可能な位置に配置されている。また、第2ケース部材24の第2対向面24dにおいて、操作部材21の突出部21aが当接可能な位置は、横方向における第2固定接点部24gの接触部24hの外方側に位置している。なお、図22においては、シート部材29を図示していないが、実際には、第1ケース部材25の第1対向面25cと第2ケース部材24の第2対向面24dとの間にはシート部材29が挟まれている。 As shown in FIG. 28, the movable contact member 22 is accommodated in the second space 24 b of the second case member 24. The movable contact member 22 is disposed in a direction in which the movable contact portion 22a protrudes forward (X1 direction), and the permanent contact portion 22c (on the Z2 direction side shown in FIG. 23) is the innermost surface 24e of the second space portion 24b. The second fixed contact portion 24g is in contact with the contact portion 24h (see FIG. 19) of the second fixed contact portion 24g exposed on the other side, and the other permanent contact portion 22c sandwiches the first fixed contact portion 24f on the innermost surface 24e. It is in contact with a location (see FIG. 19) that protrudes so as to be at the same height as the peripheral contact portion 24q at a position facing 24g. The movable contact portion 22a is separated from the first fixed contact portion 24f. The sheet member 29 is disposed so as to cover the second space portion 24b where the movable contact member 22 is disposed, with the adhesive surface 29a facing the second space portion 24b. The sheet member 29 is held on the second facing surface 24d of the second case member 24 by the adhesive force of the adhesive surface 29a, and the movable contact member 22 is held in the second space portion 24b, so that the movable contact member 22 and the second contact surface 22 2 is always in contact with the fixed contact portion 24g. Since the sheet member 29 has flexibility, when the sheet member 29 is pressed through the sheet member 29, the movable contact portion 22a of the movable contact member 22 is movable in the second space portion 24b and is in the center contact. The portion 24n (see FIG. 19) is held at a position where it can come into contact. The operation member 21 is held in the first space portion 25a of the first case member 25 in a state where the button portion 21c is inserted into the opening portion 25e from the first space portion 25a side. Note that a part of the operation member 21 (protruding portion 21a (see FIG. 24)) is arranged and guided in the protruding shape portion 25d (see FIG. 21), and is slidably held in the first space portion 25a. Has been. The first case member 25 holding the operation member 21 in the first space portion 25 a engages with the second case member 24 in a direction in which the actuator portion 21 b of the operation member 21 faces the sheet member 29. That is, the sheet member 29 is sandwiched between the first facing surface 25c and the second facing surface 24d, and the first space portion 25a and the second space portion 24b define the space portion 23a that houses the operation member 21 and the movable contact member 22. Engage to form. Thus, by engaging the first case member 25 and the second case member 24, the actuator portion 21 b of the operation member 21 and the movable contact portion 22 a of the movable contact member 22 are brought into contact with each other via the sheet member 29. Further, the front cover member 27 is engaged with the first case member 25 so as to cover the space portion 23a in a state where the button portion 21c of the operation member 21 protrudes from the through hole 27a. Further, the rear cover member 28 covers the rear side of the case 23 (second case member 24) with the base portion 28a, and is engaged with the second case member 24 with the arm portion 28b extending forward. . Further, the arm portion 28 b extending forward is engaged with the engaging portion 27 b of the front cover member 27, and the front cover member 27 and the rear cover member 28 are integrated to form the cover member 26. In the second embodiment, the engagement between the engagement portion 27 b and the arm portion 28 b is such that the tip end portion 28 c of the arm portion 28 b of the rear cover member 28 is inserted into the engagement hole portion 27 c of the front cover member 27. The front cover member 27 is bent and engaged inward on the front side. Thus, by forming the cover member 26 (see FIG. 25), the first case member 25 and the second case member 24 press and sandwich the sheet member 29. In this way, the push switch 200 in the second embodiment is configured. When the push switch 200 is formed, as shown in FIG. 22, a part of the projecting shape part 25d and a part of the second facing surface 24d are arranged to face each other. Therefore, the protruding portion 21a of the operating member 21 that is movably disposed along the protruding shape portion 25d is disposed at a position that can contact the second facing surface 24d. However, when the movable contact member 22 is pressed via the operation member 21 and the movable contact portion 22a is brought into contact with the fixed contact portion 24a (first fixed contact portion 24f), the protruding portion 21a extends from the second facing surface 24d. It is separated. In addition, since the portion where the long side and the short side of the outer shape of the second opening 24c intersect is disposed at a position corresponding to the protruding shape portion 25d, the protruding portion 21a of the operation member 21 is provided with the second opening 24c. The outer shape is disposed at a position where the long side and the short side of the outer shape can contact the second facing surface 24d. Further, on the second facing surface 24d of the second case member 24, the position where the protruding portion 21a of the operation member 21 can abut is located on the outer side of the contact portion 24h of the second fixed contact portion 24g in the lateral direction. ing. Although the sheet member 29 is not illustrated in FIG. 22, the sheet is actually between the first facing surface 25 c of the first case member 25 and the second facing surface 24 d of the second case member 24. The member 29 is sandwiched.
次にプッシュスイッチ200の動作について図28ないし図30を用いて説明する。図29は図28に示す状態から押圧操作された後の状態を示す模式断面図である。図30は第2実施形態におけるプッシュスイッチ200がオーバーストロークになった状態を示す模式断面図である。 Next, the operation of the push switch 200 will be described with reference to FIGS. 29 is a schematic cross-sectional view showing a state after a pressing operation is performed from the state shown in FIG. FIG. 30 is a schematic cross-sectional view showing a state where the push switch 200 according to the second embodiment has an overstroke.
図28に示す状態は、プッシュスイッチ200が操作されていない初期状態を示している。図28に示す状態においては、常接接点部22cは第2固定接点部24gと接触しているが、可動接点部22aは第1固定接点部24fとは離間している。つまり、図28に示す状態は、第1固定接点部24fと第2固定接点部24gとの電気的な導通は無い状態である。図28に示す状態から、図29に示すように、操作部材21を後方側(X2方向)へ押圧すると、シート部材29を介して可動接点部22aに接触するアクチュエータ部21bは可動接点部22aを後方側へ押圧する。押圧された可動接点部22aは後方側へ撓んだ後に反転し、第1固定接点部24fに接触する。可動接点部22aと第1固定接点部24fとが接触することで、第1固定接点部24fと第2固定接点部24gとは、可動接点部材22を介して電気的に導通される。また、操作部材21への押圧を解除すると、可動接点部22aの弾性力により、図28に示す初期状態に復帰し、第1固定接点部24fと第2固定接点部24gとの電気的な導通は無い状態となる。このように、可動接点部材22と第1固定接点部24fとが接離し、第1固定接点部24fと第2固定接点部24gとの電気的な導通状態を切り替えることで入力を行なうことができ、外部と電気的に接続可能な外部接続端子24rを介して入力信号として出力され、プッシュスイッチとして機能する。また、可動接点部22aと第1固定接点部24fとが接触するとき、操作部材21の鍔部21d(突出部21a(図24参照))と第2ケース部材24の第2対向面24dとは離間している。しかし、操作者により操作部材21を必要以上の力で押し込み操作された場合や、プッシュスイッチ200が取り付けられた電子機器などを誤って落下させ、操作部材21を押圧する方向に衝撃が加わった場合など、可動接点部22aと第1固定接点部24fとが接触したあとにオーバーストロークになる場合もある。このようなオーバーストロークとなった場合には、図30に示すように、操作部材21のアクチュエータ部21bが潰れるとともに、突出部21a(図24参照)が第2ケース部材24の第2対向面24dに接触し、操作部材21がさらに後方へ押し込まれるのを阻止する。なお、図30においては、アクチュエータ部21bがほとんどなくなるまで潰れるように図示しているが、実際には、アクチュエータ部21bの先端部が潰れる程度であり、アクチュエータ部21bの先端部が潰れた後であっても、プッシュスイッチ200への入力操作は可能である。 The state shown in FIG. 28 shows an initial state where the push switch 200 is not operated. In the state shown in FIG. 28, the normal contact portion 22c is in contact with the second fixed contact portion 24g, but the movable contact portion 22a is separated from the first fixed contact portion 24f. That is, the state shown in FIG. 28 is a state where there is no electrical continuity between the first fixed contact portion 24f and the second fixed contact portion 24g. From the state shown in FIG. 28, as shown in FIG. 29, when the operating member 21 is pressed backward (X2 direction), the actuator portion 21b that contacts the movable contact portion 22a via the sheet member 29 moves the movable contact portion 22a. Press backwards. The pressed movable contact portion 22a is inverted after being bent backward, and comes into contact with the first fixed contact portion 24f. When the movable contact portion 22a and the first fixed contact portion 24f come into contact with each other, the first fixed contact portion 24f and the second fixed contact portion 24g are electrically connected via the movable contact member 22. Further, when the pressing on the operation member 21 is released, the initial state shown in FIG. 28 is restored by the elastic force of the movable contact portion 22a, and the electrical continuity between the first fixed contact portion 24f and the second fixed contact portion 24g. There will be no state. As described above, the movable contact member 22 and the first fixed contact portion 24f are brought into contact with and separated from each other, and the input can be performed by switching the electrical conduction state between the first fixed contact portion 24f and the second fixed contact portion 24g. It is output as an input signal via an external connection terminal 24r that can be electrically connected to the outside, and functions as a push switch. Further, when the movable contact portion 22a and the first fixed contact portion 24f come into contact with each other, the flange portion 21d (projecting portion 21a (see FIG. 24)) of the operation member 21 and the second facing surface 24d of the second case member 24 are It is separated. However, when the operation member 21 is pushed in with an excessive force by the operator, or when an electronic device or the like to which the push switch 200 is attached is accidentally dropped and an impact is applied in the direction in which the operation member 21 is pressed. For example, an overstroke may occur after the movable contact portion 22a and the first fixed contact portion 24f come into contact with each other. In such an overstroke, as shown in FIG. 30, the actuator portion 21 b of the operation member 21 is crushed and the protruding portion 21 a (see FIG. 24) is the second facing surface 24 d of the second case member 24. This prevents the operation member 21 from being pushed further backward. In FIG. 30, the actuator portion 21b is shown to be crushed until it almost disappears, but in reality, the tip portion of the actuator portion 21b is crushed, and after the tip portion of the actuator portion 21b is crushed. Even if it exists, the input operation to the push switch 200 is possible.
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。なお、一部の効果の説明には図16または図31を用いて説明する。図31は図15に記載のG部を拡大して示す拡大図である。 Hereinafter, the effect by having set it as this embodiment is demonstrated. Some effects will be described with reference to FIG. 16 or FIG. FIG. 31 is an enlarged view showing a G portion shown in FIG.
本実施形態のプッシュスイッチ200では、操作部材21と、可動接点部材22と、固定接点部24aを有し、操作部材21および可動接点部材22を収容可能で前方側が開放された空間部23aを備えるケース23と、空間部23aを覆う前方カバー部材27と、ケース23の後方側を覆う基部28aと、基部28aの両端から前方側にそれぞれ延出している腕部28bとを備える後方カバー部材28と、を有するプッシュスイッチにおいて、前方カバー部材27には、操作部材21が突出する貫通穴27aと、両端側に後方カバー部材28の腕部28bと係合される係合部27bとが設けられており、前方カバー部材27の係合部27bに後方カバー部材28の腕部28bがそれぞれ係合されて前方カバー部材27と後方カバー部材28とが一体化されている、構成とした。 The push switch 200 according to the present embodiment includes an operation member 21, a movable contact member 22, and a fixed contact portion 24a. The push switch 200 includes a space portion 23a that can accommodate the operation member 21 and the movable contact member 22 and is open on the front side. A rear cover member 28 including a case 23, a front cover member 27 covering the space portion 23a, a base portion 28a covering the rear side of the case 23, and arm portions 28b extending from both ends of the base portion 28a to the front side. In the push switch having the above, the front cover member 27 is provided with a through hole 27a from which the operation member 21 protrudes, and an engagement portion 27b to be engaged with the arm portion 28b of the rear cover member 28 at both ends. The arm portion 28b of the rear cover member 28 is engaged with the engaging portion 27b of the front cover member 27, respectively, so that the front cover member 27 and the rear cover member 28 are engaged. There are integrated, it has a structure.
これにより、後方カバー部材28の基部28aがケース23の後方側を覆う、すなわちケース23の後方側には後方カバー部材28が分断された箇所が無いとともに、2つの腕部28bを前方カバー部材27と係合させて一体化させる構成とした。これにより、押圧されたときに、選考技術のように後方カバー部材28の分断された箇所が広がることはないので、先行技術に比べて前方側からの押し込み強度を向上させることができる。よって、基板取り付け後に前方側からの押圧操作に対する耐性のある横押しタイプのプッシュスイッチを提供することができる、という効果を奏する。 Accordingly, the base portion 28a of the rear cover member 28 covers the rear side of the case 23, that is, there is no portion where the rear cover member 28 is divided on the rear side of the case 23, and the two arm portions 28b are connected to the front cover member 27. To be integrated with each other. Thereby, since the part where the rear cover member 28 was divided does not spread like the selection technique when pressed, the pushing strength from the front side can be improved as compared with the prior art. Therefore, there is an effect that it is possible to provide a lateral push type push switch that is resistant to a pressing operation from the front side after the substrate is attached.
また、本実施形態のプッシュスイッチ200では、係合部27bが貫通孔からなる係合穴部27cであり、後方カバー部材28の腕部28bが係合穴部27cに挿入され、前方カバー部材27の前方側にて内方側に折り曲げられて係合している、構成とした。 Further, in the push switch 200 of the present embodiment, the engaging portion 27b is an engaging hole portion 27c formed of a through hole, and the arm portion 28b of the rear cover member 28 is inserted into the engaging hole portion 27c, so that the front cover member 27 is inserted. It is set as the structure which is bend | folded and engaged in the inward side in the front side.
これにより、係合部27bを貫通孔からなる係合穴部27cとすることで、係合部27bを簡易に構成することができる。また、後方カバー部材28の腕部28bが係合穴部27cに挿入され、折り曲げることで係合する構成とすることで、前方カバー部材27と後方カバー部材28とを十分な保持力で係合することができる。したがって、簡易な構成で、前方カバー部材27と後方カバー部材28とを十分な保持力で係合することができる、という効果を奏する。 Thereby, the engaging part 27b can be simply comprised by making the engaging part 27b into the engaging hole part 27c which consists of a through-hole. In addition, the arm portion 28b of the rear cover member 28 is inserted into the engagement hole portion 27c and engaged by being bent, so that the front cover member 27 and the rear cover member 28 are engaged with a sufficient holding force. can do. Therefore, the front cover member 27 and the rear cover member 28 can be engaged with each other with a sufficient holding force with a simple configuration.
また、本実施形態のプッシュスイッチ200では、前方カバー部材27の係合穴部27cの開口形状は幅方向における外方側が円弧形状となっており、後方カバー部材28の腕部28bの先端部28cは係合穴部27cに挿入可能に形成されており、係合穴部27cに挿入されて、内方側に折り曲げられて係合されている、構成とした。 Further, in the push switch 200 of the present embodiment, the opening shape of the engagement hole portion 27c of the front cover member 27 has an arc shape on the outer side in the width direction, and the distal end portion 28c of the arm portion 28b of the rear cover member 28. Is formed so as to be insertable into the engagement hole 27c, and is inserted into the engagement hole 27c, bent inward and engaged.
これにより、係合穴部27cの開口形状を、幅方向における外方側が円弧形状とすることで、幅方向における外方側においては上下方向の寸法が内方側よりも小さくなる。係合穴部27cと腕部28bとを係合するために、腕部28bの先端部28cを内方側に折り曲げたときに、腕部28bが係合穴部27cの幅方向における外方側へ広がりやすい。仮に広がったとしても、図31に破線で示すように、腕部28bが係合穴部27cの幅方向における外方側(図31においてはY1方向側)の円弧形状の面に接触し、外方側へ広がることなく、腕部28bは内方側へ寄せられる。したがって、前方カバー部材27と後方カバー部材28とをガタのない状態で固定することができ、外れにくい強固な係合とすることができる、という効果を奏する。 Thereby, the dimension of the up-down direction is smaller on the outer side in the width direction than on the inner side by setting the opening shape of the engagement hole portion 27c to an arc shape on the outer side in the width direction. When the distal end portion 28c of the arm portion 28b is bent inward to engage the engagement hole portion 27c with the arm portion 28b, the arm portion 28b is located outward in the width direction of the engagement hole portion 27c. Easy to spread. Even if it spreads, as shown by a broken line in FIG. 31, the arm portion 28b contacts the arc-shaped surface on the outer side in the width direction of the engagement hole portion 27c (the Y1 direction side in FIG. 31) The arm portion 28b is moved toward the inner side without spreading toward the inner side. Therefore, it is possible to fix the front cover member 27 and the rear cover member 28 without any backlash and to achieve a strong engagement that is difficult to come off.
また、本実施形態のプッシュスイッチ200では、固定接点部24aを有し、可動接点部材22を収容する第2空間部24bを備える第2ケース部材24と、第2ケース部材24と係合して、操作部材21を案内するようにその一部を収容する第1空間部25aを備える第1ケース部材25と、からなるプッシュスイッチにおいて、第2ケース部材24は第2空間部24bが開口した第2開口24cのある第2対向面24dを有し、第1ケース部材25は第1空間部25aが開口した第1開口25bのある第1対向面25cを有し、第2ケース部材24と第1ケース部材25とは、第2対向面24dと第1対向面25cとを対向させて係合され、第1開口25bの外形形状を第2開口24cの外形形状に重ねたとき、第1開口25bの外形形状は第2開口24cの外形形状からはみ出す突出形状部25dを有し、操作部材21は第1開口25bの外形形状に沿うように形成されて、突出形状部25dに配置される突出部21aを有し、操作部材21を介して可動接点部材22を固定接点部24aに接触させたときに、突出部21aは第2対向面24dから離間している、構成とした。 Further, in the push switch 200 of the present embodiment, the second case member 24 having the fixed contact portion 24 a and having the second space portion 24 b for accommodating the movable contact member 22 is engaged with the second case member 24. In the push switch comprising the first case member 25 including the first space portion 25a that accommodates a part of the operation member 21 so as to guide the operation member 21, the second case member 24 has the second space portion 24b opened. The first case member 25 has a first facing surface 25c with a first opening 25b in which the first space 25a is opened, and the second case member 24 and the second case member 24 have a second facing surface 24d with two openings 24c. The first case member 25 is engaged with the second facing surface 24d and the first facing surface 25c facing each other. When the outer shape of the first opening 25b is overlapped with the outer shape of the second opening 24c, the first opening is formed. 25b external shape Has a protruding portion 25d that protrudes from the outer shape of the second opening 24c, and the operating member 21 has a protruding portion 21a that is formed along the outer shape of the first opening 25b and is disposed in the protruding shape portion 25d. When the movable contact member 22 is brought into contact with the fixed contact portion 24a via the operation member 21, the protruding portion 21a is separated from the second facing surface 24d.
これにより、第1開口25bの外形形状を第2開口24cの外形形状に重ねたとき、第1開口25bの外形形状は第2開口24cの外形形状からはみ出すように形成された突出形状部25dを有し、操作部材21は第1開口25bの外形形状に沿うように形成されており、突出形状部25dに配置される突出部21aを有する構成とした。したがって、誤って操作部材21が無理押しされるなど、オーバーストロークとなったときに、操作部材21の突出部21aを第2対向面24dに当接させることでストッパを構成して、過剰な押し込み時の耐性を向上させることができる。このような構造であれば、押圧操作された方向に可動接点部材22が配置された構造であっても、過剰なオーバーストロークを止めることができる。したがって、押圧操作された方向に可動接点部材22が配置され、過剰な押し込みに対応可能なプッシュスイッチを提供することができる、という効果を奏する。 As a result, when the outer shape of the first opening 25b is overlapped with the outer shape of the second opening 24c, the outer shape of the first opening 25b is changed from the protruding shape portion 25d formed so as to protrude from the outer shape of the second opening 24c. The operation member 21 is formed so as to follow the outer shape of the first opening 25b, and has a protruding portion 21a disposed on the protruding shape portion 25d. Therefore, when the operation member 21 is accidentally pushed by force, for example, when an overstroke occurs, a stopper is formed by bringing the protruding portion 21a of the operation member 21 into contact with the second facing surface 24d, and excessive push-in is performed. Time tolerance can be improved. With such a structure, an excessive overstroke can be stopped even if the movable contact member 22 is arranged in the direction in which the pressing operation is performed. Therefore, there is an effect that the movable contact member 22 is arranged in the direction in which the pressing operation is performed, and a push switch that can cope with excessive pressing can be provided.
また、本実施形態のプッシュスイッチ200では、第2開口24cの外形形状は、長手辺が直線形状で、短手辺が円弧形状の長方形状であり、可動接点部材22は第2開口24cの外形形状に沿うように形成され、操作部材21の突出部21aは、第2開口24cの外形形状の長手辺と短手辺とが交差する箇所で、第2対向面24dに接触可能に形成されている、構成とした。 Further, in the push switch 200 of the present embodiment, the outer shape of the second opening 24c is a rectangular shape having a long side of a straight line and a short side of an arc, and the movable contact member 22 has an outer shape of the second opening 24c. The protruding portion 21a of the operation member 21 is formed so as to be in contact with the second facing surface 24d at a location where the long side and the short side of the outer shape of the second opening 24c intersect. It was configured.
これにより、第2開口24cの外形形状を、長手辺が直線形状で、短手辺が円弧形状の長方形状とし、短手辺と長手辺とが交差する位置で突出部21aが第2対向面24dに接触可能とすることで、仮にオーバーストロークになった場合に、突出部21aと第2対向面24dとの接触面積を大きくすることができる。すなわち、より大きな荷重が加わった場合にも、破損することなく操作部材21の移動を止めることができる。したがって、押圧操作された方向に可動接点部材22が配置され、過剰な押し込みに対応可能なプッシュスイッチを提供することができる、という効果を奏する。 As a result, the outer shape of the second opening 24c is a rectangular shape having a long side having a linear shape and a short side having an arc shape, and the projecting portion 21a has a second opposing surface at a position where the short side and the long side intersect. By making the contact with 24d possible, the contact area between the protruding portion 21a and the second facing surface 24d can be increased if an overstroke occurs. That is, even when a larger load is applied, the movement of the operation member 21 can be stopped without being damaged. Therefore, there is an effect that the movable contact member 22 is arranged in the direction in which the pressing operation is performed, and a push switch that can cope with excessive pressing can be provided.
また、本実施形態のプッシュスイッチ200では、可動接点部材22は、ばね性を有する金属板から形成されており、操作部材21は、可動接点部材22を押圧するための合成樹脂材からなるアクチュエータ部21bを有し、アクチュエータ部21bは、可動接点部材22を撓ませることが可能で、かつ第2ケース部材24を破損させない所定の荷重が加わったときに潰れる、構成とした。 Further, in the push switch 200 of the present embodiment, the movable contact member 22 is formed from a metal plate having a spring property, and the operation member 21 is an actuator portion made of a synthetic resin material for pressing the movable contact member 22. The actuator portion 21b is configured to be able to bend the movable contact member 22 and to be crushed when a predetermined load that does not damage the second case member 24 is applied.
これにより、可動接点部材22を撓ませることが可能で、かつ第2ケース部材24を破損させない所定の荷重が加わったときに、アクチュエータ部21bが潰れる構成としたことで、仮にオーバーストロークになった場合には、先ず、アクチュエータ部21bが潰れ、そのあとに突出部21aと第2対向面24dとが当接することになる。そのため、第2ケース部材24に過剰な押圧付加が加わることによる、固定接点部24aの周辺の破損を軽減することができる。また、アクチュエータ部21bは、オーバーストロークの移動量分であるわずかな量しか潰れないので、スイッチ機能が完全に喪失することは無い。したがって、押圧操作された方向に可動接点部材22が配置され、過剰な押し込みに対応可能なプッシュスイッチを提供することができる、という効果を奏する。 Accordingly, the movable contact member 22 can be bent and the actuator portion 21b is crushed when a predetermined load that does not damage the second case member 24 is applied. In this case, the actuator portion 21b is first crushed, and then the protruding portion 21a and the second facing surface 24d come into contact with each other. Therefore, damage around the fixed contact portion 24a due to excessive pressing applied to the second case member 24 can be reduced. Further, since the actuator portion 21b can be crushed by a small amount corresponding to the amount of movement of the overstroke, the switch function is not completely lost. Therefore, there is an effect that the movable contact member 22 is arranged in the direction in which the pressing operation is performed, and a push switch that can cope with excessive pressing can be provided.
また、本実施形態のプッシュスイッチ200では、固定接点部24aは、第2空間部24bの第2開口24cに対向する側の面である最奥面24eに形成され、最奥面24eの中央部分に形成される第1固定接点部24fと、最奥面24eにおいて第2空間部24bの長手側の壁の近くに形成される第2固定接点部24gと、からなり、第1固定接点部24fおよび第2固定接点部24gは、可動接点部材22が接触する接触部24hを有しており、第2ケース部材24の第2対向面24dにおいて、操作部材21の突出部21aが当接可能な位置は、横方向における第2固定接点部24gの接触部24hの外方側に位置している、構成とした。 Further, in the push switch 200 of the present embodiment, the fixed contact portion 24a is formed on the innermost surface 24e that is a surface facing the second opening 24c of the second space portion 24b, and a central portion of the innermost surface 24e. The first fixed contact portion 24f formed on the innermost surface 24e and the second fixed contact portion 24g formed near the longitudinal wall of the second space portion 24b. The second fixed contact portion 24g has a contact portion 24h with which the movable contact member 22 contacts, and the protruding portion 21a of the operation member 21 can come into contact with the second facing surface 24d of the second case member 24. The position is set to be located on the outer side of the contact portion 24h of the second fixed contact portion 24g in the lateral direction.
これにより、横方向における第2固定接点部24gの接触部24hの外方側であれば、第2空間部24bの最奥面24eから固定接点部24aが露出する箇所がなくなるので、第2空間部24bを設ける必要がなくなり、第2ケース部材24の側壁を厚くすることができる。したがって、第2ケース部材24の第2対向面24dにおいて、操作部材21の突出部21aが当接可能な位置を、横方向における第2固定接点部24gの接触部24hの外方側とすることで、突出部21aと第2対向面24dとの接触面積を大きくすることができる。よって、より大きな荷重が加わった場合にも、破損することなく操作部材21の移動を止めることができる、という効果を奏する。 Thereby, if it is on the outer side of the contact portion 24h of the second fixed contact portion 24g in the lateral direction, there is no place where the fixed contact portion 24a is exposed from the innermost surface 24e of the second space portion 24b. It is not necessary to provide the portion 24b, and the side wall of the second case member 24 can be thickened. Therefore, on the second facing surface 24d of the second case member 24, the position where the protruding portion 21a of the operation member 21 can come into contact is the outer side of the contact portion 24h of the second fixed contact portion 24g in the lateral direction. Thus, the contact area between the protruding portion 21a and the second facing surface 24d can be increased. Therefore, even when a larger load is applied, there is an effect that the movement of the operation member 21 can be stopped without being damaged.
また、本実施形態のプッシュスイッチ200では、固定接点部24aを有し、操作部材21及び可動接点部材22を収容する空間部23aを備えるケース23と、空間部23aを覆うカバー部材26と、を備えたプッシュスイッチにおいて、固定接点部24aは空間部23aの一面である最奥面24eに露出して形成されており、ケース23は最奥面24eの後方側に突出するように形成された本体部24kを有し、本体部24kには、後方側の端部から前方へ向かって一部切り欠かれた切り欠き部24mを有し、固定接点部24aは、可動接点部材22と接離する第1固定接点部24fと、可動接点部材22と常時接触する第2固定接点部24gと、からなり、第1固定接点部24fは、可動接点部材22と接触する中央接触部24nと、中央接触部24nに連続して最奥面24eから露出するとともに、中央接触部24nの周囲へ延出された延出部24pと、を有し、中央接触部24nは、最奥面24eの本体部24kに対応した箇所に配置されている、構成とした。 Further, in the push switch 200 of the present embodiment, the case 23 having the fixed contact portion 24a and including the space portion 23a that houses the operation member 21 and the movable contact member 22, and the cover member 26 that covers the space portion 23a. In the provided push switch, the fixed contact portion 24a is formed so as to be exposed at the innermost surface 24e, which is one surface of the space portion 23a, and the case 23 is formed so as to protrude to the rear side of the innermost surface 24e. The main body portion 24k has a notch portion 24m partially cut away from the rear end portion toward the front, and the fixed contact portion 24a contacts and separates from the movable contact member 22. The first fixed contact portion 24f and the second fixed contact portion 24g that is always in contact with the movable contact member 22, and the first fixed contact portion 24f is a central contact portion 24n that is in contact with the movable contact member 22. The center contact portion 24n is exposed from the innermost surface 24e continuously to the center contact portion 24n, and has an extended portion 24p extending around the center contact portion 24n. The center contact portion 24n is a main body of the innermost surface 24e. It was set as the structure arrange | positioned in the location corresponding to the part 24k.
これにより、最奥面24eの後方側で厚みのある本体部24kに対応した箇所に中央接触部24nを配置するとともに、中央接触部24nの周囲に延出する延出部24pを設けることで、押し込み操作されたときに、ケース23に厚みのある部分で受け止めるとともに、受け止める面積を広げることができる。したがって、単位面積当たりで受け止める荷重を小さくするとともに、荷重に対して強い部分で受けることができる。よって、押し込み耐性の高いプッシュスイッチを提供することができる、という効果を奏する。 Thereby, while arrange | positioning the center contact part 24n in the location corresponding to the thick main-body part 24k on the back side of the innermost surface 24e, providing the extension part 24p extended around the center contact part 24n, When the push-in operation is performed, the case 23 can be received at a thick portion and the area to be received can be increased. Therefore, the load received per unit area can be reduced and received at a portion strong against the load. Therefore, it is possible to provide a push switch with high push resistance.
また、本実施形態のプッシュスイッチ200では、第2固定接点部24gの可動接点部材22と接触する周辺接触部24qは、最奥面24eの切り欠き部24mに対応した箇所に配置されている、構成とした。 Further, in the push switch 200 of the present embodiment, the peripheral contact portion 24q that contacts the movable contact member 22 of the second fixed contact portion 24g is disposed at a location corresponding to the notch portion 24m of the innermost surface 24e. The configuration.
これにより、周辺接触部24qを切り欠き部24mに対応した箇所に配置することで、本体部24kに対応した箇所を、押し込み操作時に最も負荷がかかる中央接触部24nおよび延出部24pに、より大きな面積を確実に割り当てることが可能となる。したがって、より押し込み耐性の高いプッシュスイッチを提供することができる、という効果を奏する。 Thereby, by arranging the peripheral contact portion 24q at a location corresponding to the cutout portion 24m, the location corresponding to the main body portion 24k can be more concentrated on the central contact portion 24n and the extension portion 24p that are most loaded during the pushing operation. A large area can be reliably allocated. Therefore, it is possible to provide a push switch having higher push-in resistance.
また、本実施形態のプッシュスイッチ200では、金属板からなりケース23にインサート成型された回路部材30は、一端に固定接点部24aを有するとともに、他端には、ケース23の後方側から露出して外部と電気的に接続可能な外部接続端子24rを有し、回路部材30の固定接点部24aと外部接続端子24rとの間には、上方からの平面視で、回路部材30が延出する方向に対して交差する方向へ延出する許容部24sが形成され、許容部24sの幅寸法は、許容部24sを間に挟んだ箇所の幅寸法よりも小さい、構成とした。 In the push switch 200 of the present embodiment, the circuit member 30 made of a metal plate and insert-molded in the case 23 has a fixed contact portion 24a at one end and is exposed from the rear side of the case 23 at the other end. The circuit member 30 extends between the fixed contact portion 24a of the circuit member 30 and the external connection terminal 24r in plan view from above. An allowable portion 24s extending in a direction crossing the direction is formed, and the width of the allowable portion 24s is smaller than the width of the portion sandwiching the allowable portion 24s therebetween.
プッシュスイッチ200が電子機器などに取り付けられる場合には、プッシュスイッチ200は、図16に示すような、切り欠きが設けられた基板CB2に取り付けられる。プッシュスイッチ200は、基板CB2の切り欠き部分の端部と切り欠き部24mとが係合するとともに、外部接続端子24rおよびケース23の複数個所を基板CB2の上面に設けられたランドLN2上に配置され、半田付けなどにより固定される。これにより、例えば、電子機器に搭載された状態で押し込み操作をされたとき、外部接続端子24rは電子機器に半田付けなどにより固定されているため、押し込み荷重は外部接続端子24rに加わることになる。外部接続端子24rと固定接点部24aとの間に、前後の箇所より幅寸法が小さい許容部24sを設けることで、押し込み操作をされたときに、押し込みされた方向へ微少量ではあるが許容部24sが撓むことで、外部接続端子24rにかかる負荷を吸収し軽減することができる。したがって、押し込み操作により半田付けされた外部接続端子24rが外れるような不具合が発生し難くなる。よって、さらに押し込み耐性の高いプッシュスイッチを提供することができる、という効果を奏する。 When the push switch 200 is attached to an electronic device or the like, the push switch 200 is attached to a substrate CB2 provided with a notch as shown in FIG. In the push switch 200, the end of the cutout portion of the substrate CB2 and the cutout portion 24m are engaged, and the external connection terminal 24r and a plurality of places of the case 23 are disposed on the land LN2 provided on the upper surface of the substrate CB2. And fixed by soldering or the like. Thereby, for example, when a push-in operation is performed in a state where the electronic device is mounted on the electronic device, the external connection terminal 24r is fixed to the electronic device by soldering or the like, so that the push-in load is applied to the external connection terminal 24r. . By providing an allowance portion 24s having a smaller width than the front and rear portions between the external connection terminal 24r and the fixed contact portion 24a, when the push operation is performed, the allowance portion is slightly small in the pushed-in direction. By bending 24s, the load applied to the external connection terminal 24r can be absorbed and reduced. Therefore, it is difficult to cause a problem that the external connection terminal 24r soldered by the pushing operation is detached. Therefore, it is possible to provide a push switch with higher push resistance.
