Description

本発明は押釦スイッチに関する。 The present invention relates to a push button switch.

従来の押釦スイッチには、部品収容用のケースと、このケースに対してプッシュ操作可能なスライド部材と、このスライド部材をロック状態とする係止ピンと、この係止ピンの移動方向と直交する方向に移動可能な可動部材とを備えたものがある（例えば特許文献１）。 A conventional pushbutton switch includes a case for housing a component, a slide member that can be pushed with respect to the case, a lock pin that locks the slide member, and a direction orthogonal to the moving direction of the lock pin. (For example, patent document 1).

ケースは、部品収容空間を有し、上ケース及び下ケースからなる分割ケースによって形成されている。下ケースには固定端子が取り付けられている。 The case has a component housing space and is formed by a divided case including an upper case and a lower case. A fixed terminal is attached to the lower case.

スライド部材は、ハート形カム溝（一部）及び摺動孔を有し、ケースにプッシュ操作可能に配置されている。スライド部材には、固定端子に対応する可動端子が取り付けられている。また、スライド部材には、初期位置に復帰する方向のばね力が復帰用ばねによって付与されている。 The slide member has a heart-shaped cam groove (part) and a slide hole, and is arranged on the case so as to be pushed. A movable terminal corresponding to the fixed terminal is attached to the slide member. Further, the spring force in the direction of returning to the initial position is applied to the slide member by the return spring.

係止ピンは、略コ字状のロック部材からなり、ケースに保持され、かつハート形カム溝側へのばね力が板ばねによって付与されている。そして、係止ピンは、その溝側端部がスライド部材の第１のプッシュ操作による移動に伴いハート形カム溝上を移動し、ハート形カム溝の係合位置での係合によってスライド部材をロック状態とするように構成されている。また、係止ピンは、ハート形カム溝の係合位置に対する係合状態において、スライド部材の第２のプッシュ操作によってハート形カム溝との係合状態を解除してスライド部材をアンロック状態とするように構成されている。 The locking pin is formed of a substantially U-shaped locking member, is held by the case, and a spring force is applied to the heart-shaped cam groove side by a leaf spring. The groove-side end of the locking pin moves on the heart-shaped cam groove as the slide member is moved by the first push operation, and the slide member is locked by engagement at the engagement position of the heart-shaped cam groove. It is configured to be in a state. Further, in the engaged state with respect to the engagement position of the heart-shaped cam groove, the locking pin releases the engaged state with the heart-shaped cam groove by the second push operation of the slide member, and the slide member is unlocked. Is configured to do.

可動部材は、駆動部を有し、スライド部材の摺動孔に移動可能に配置され、かつ駆動部をケース外に露出させる方向のばね力がコイルばねによって付与されている。そして、可動部材は、スライド部材と共にハート形カム溝を形成するように構成されている。 The movable member has a drive unit, is movably disposed in the slide hole of the slide member, and a spring force in a direction to expose the drive unit to the outside of the case is applied by the coil spring. The movable member is configured to form a heart-shaped cam groove together with the slide member.

以上の構成により、スライド部材を復帰用ばねのばね力に抗してプッシュ操作すると、係止ピンとハート形カム溝との相対位置が変化し、係止ピンが板ばねを支点としてハート形カム溝内を移動する。 With the above configuration, when the slide member is pushed against the spring force of the return spring, the relative position of the locking pin and the heart-shaped cam groove changes, and the locking pin uses the leaf spring as a fulcrum to form a heart-shaped cam groove. Move in.

これにより、係止ピンがハート形カム溝の係合位置で係合され、スライド部材がロック状態とされる。 As a result, the locking pin is engaged at the engagement position of the heart-shaped cam groove, and the slide member is locked.

一方、スライド部材をロック状態からプッシュ操作すると、係止ピンがハート形カム溝内を移動し、スライド部材が復帰用ばねによって初期位置に復帰する。 On the other hand, when the slide member is pushed from the locked state, the locking pin moves in the heart-shaped cam groove, and the slide member is returned to the initial position by the return spring.

このように、スライド部材が往復動作すると、この往復動作に連動して可動端子と固定端子との接触状態が変化して押釦スイッチの切り替えが行われる。 Thus, when the slide member reciprocates, the contact state between the movable terminal and the fixed terminal changes in conjunction with the reciprocation, and the push button switch is switched.

係止面２０は、爪部４ｃの係止状態において、復帰用スプリング１１（図１に示す）によるばね力を含んで互いに直交する３方向ｘ，ｙ，ｚのばね力を受けるばね力受面２０ａ，２０ｂ，２０ｃを有し、スイッチ動作用の第２のガイド面１７とスイッチ動作用の第３のガイド面１８との間に配置されている。そして、係止面２０は、ばね力受面２０ａが復帰用スプリング１１からスイッチ操作部材３（爪部４ｃ）を介してｚ方向のばね力を、ばね力受面２０ｂが爪部４ｃからy方向のばね力を、またばね力受面２０ｃが爪部４ｃからばね力をそれぞれ受けて爪部４ｃを係止するように構成されている。 The locking surface 20 receives a spring force in three directions x, y, and z orthogonal to each other including the spring force of the return spring 11 (shown in FIG. 1) when the claw portion 4c is locked. 20a, 20b, and 20c, which are arranged between the second guide surface 17 for switch operation and the third guide surface 18 for switch operation. The locking surface 20 has a spring force receiving surface 20a from the return spring 11 via the switch operating member 3 (claw portion 4c) and a spring force receiving surface 20b from the claw portion 4c to the y direction. The spring force receiving surface 20c receives the spring force from the claw portion 4c and locks the claw portion 4c.

このように構成された押釦スイッチ１の組み立ては、予め回路基板６等が取り付けられ、かつ復帰用スプリング１１が位置決めされた保持部材２の凹部２ａにスイッチ操作部材３の凸部３ｃを嵌合させた後、保持部材２にスイッチ操作部材３をプッシュ操作方向Ｐに沿って押し込むことにより行われる。このため、保持部材２に対するスイッチ構成部品の組み付け方向がプッシュ操作方向Ｐと一致することになり、押釦スイッチ１の組み立てを容易に行うことができる。 The pushbutton switch 1 constructed in this way is assembled by fitting the convex portion 3c of the switch operating member 3 to the concave portion 2a of the holding member 2 to which the circuit board 6 or the like is previously attached and the return spring 11 is positioned. Thereafter, the switch operation member 3 is pushed into the holding member 2 along the push operation direction P. For this reason, the assembly direction of the switch component with respect to the holding member 2 is coincident with the push operation direction P, and the push button switch 1 can be easily assembled.

第２のプッシュ操作によってスイッチ操作部材３を復帰用スプリング１１及びスイッチ操作部材３のばね力に抗してプッシュ操作方向Ｐに往動させる。この場合、スイッチ操作部材３が往動すると、この往動動作に伴い爪部４ｃが図７（ｅ）に示す係止位置からプッシュ操作方向Ｐに移動し、図７（ｆ）に示すスイッチ動作用の第３のガイド面１８を介して図７（ｇ）に示す中間位置に到達する。この際、爪部４ｃが図７（ｅ）に示す係止位置から離間して係止状態が解除される。 "Second push operation"
The switch operation member 3 is moved forward in the push operation direction P against the spring force of the return spring 11 and the switch operation member 3 by the second push operation. In this case, when the switch operation member 3 moves forward, the claw portion 4c moves in the push operation direction P from the locking position shown in FIG. 7 (e) along with the forward movement, and the switch operation shown in FIG. 7 (f). The intermediate position shown in FIG. 7G is reached via the third guide surface 18 for use. At this time, the claw portion 4c is separated from the locking position shown in FIG.

「第２のプッシュ操作の解除」
第２のプッシュ操作の解除によってスイッチ操作部材３をプッシュ操作方向Ｐと反対の方向に復動させる。この場合、スイッチ操作部材３が復動すると、この復動動作に伴い爪部４ｃが図７（ｇ）に示す中間位置からプッシュ操作方向Ｐと反対の方向に移動し、図７（ｈ）に示すスイッチ動作用の第４のガイド面１９（垂直面１９ａ）及び図７（ｉ）に示すスイッチ動作用の第４のガイド面１９（傾斜面１９ｂ）を介して図７（ａ）に示す初期位置に復帰する。また、可動端子１０が固定端子９から離間し、押釦スイッチ１がスイッチオフ状態となる。 "Release second push operation"
By releasing the second push operation, the switch operation member 3 is moved back in the direction opposite to the push operation direction P. In this case, when the switch operation member 3 moves backward, the claw portion 4c moves in the direction opposite to the push operation direction P from the intermediate position shown in FIG. 7A through the fourth guide surface 19 (vertical surface 19a) for switch operation shown and the fourth guide surface 19 (inclined surface 19b) for switch operation shown in FIG. 7 (i).
