Description
本發明是有關壓動式開關結構,尤指一種可有效清除接點上的碳化物質,並於過度按壓時確實切斷導通狀態之壓動式開關。 The present invention relates to a pressure-operated switch structure, in particular to a pressure-operated switch that can effectively remove carbonized substances on the contacts and cut off the conduction state when pressed excessively.
傳統的壓動式開關(按壓開關)在按壓(或握壓)的過程中,大多僅執行由OFF改變至ON的動作,並可隨著操作人員的手持續按壓(或握壓)而保持導通,在解除按壓(或握壓)狀態後,即可執行由ON回復至OFF的動作;然而,在許多應用的場合中,由於緊張、疲勞或誤觸等原因,在意外或緊急情形發生時,操作人員的手不但未能及時鬆開該壓動式開關(按壓開關),反而更緊握該壓動式開關(按壓開關),使相關機械無法及時停止而造成重大災害的發生。 In the process of pressing (or squeezing) the traditional push-type switch (press switch), most of them only perform the action of changing from OFF to ON, and can maintain conduction as the operator's hand continues to press (or hold) After releasing the pressing (or squeezing) state, you can perform the action of returning from ON to OFF; however, in many applications, due to tension, fatigue or accidental touch and other reasons, in the event of an accident or emergency, The operator's hand not only failed to release the pressure switch (push switch) in time, but gripped the pressure switch (push switch) tighter, so that the related machinery could not be stopped in time, causing major disasters.
在日本特許第3677199號專利案中,揭露了一種在單一按壓過程中依序執行OFF-ON-OFF動作的按壓開關結構,以下參照該案的元件符號,可知其主要結構係於一按壓開關(1)的開關殼體(3)內部設有二組C接點(9a、9b),以及至少一與該二組C接點(9a、9b)串接之常閉接點(7),於該開關殼體(3)頂側設有一按鍵(5)分別經由二開關機構(11a、11b)連動於前述C接點(9a、9b);該C接點(9a、9b)分別具有一常閉固定端子(33a、33b)、一常開固定端子(35a、35b),以及一可動端子(31a、31b),該二可動端子(31a、31b)一端係固定於該開關殼體(3)內部,另於該二可動端子(31a、31b)中段分別經由一彈簧(45a、45b)及一作動體(43a、 43b)連結於一押壓片(37a、37b)上,並使彈簧(45a、45b)一端固定在他端部(29a、29b)上,以容許可動端子(31a、31b)形成可擺動的形態。 In the Japanese Patent No. 3677199, a push switch structure that sequentially performs OFF-ON-OFF actions in a single pressing process is disclosed. The following reference to the component symbols of the case shows that its main structure is a push switch ( 1) The switch housing (3) is provided with two sets of C contacts (9a, 9b), and at least one normally closed contact (7) connected in series with the two sets of C contacts (9a, 9b). The switch housing (3) is provided with a button (5) on the top side of the switch mechanism (11a, 11b) respectively linked to the aforementioned C contacts (9a, 9b); the C contacts (9a, 9b) respectively have a constant Closed fixed terminals (33a, 33b), a normally open fixed terminal (35a, 35b), and a movable terminal (31a, 31b), one end of the two movable terminals (31a, 31b) is fixed to the switch housing (3) Inside, in the middle section of the two movable terminals (31a, 31b), a spring (45a, 45b) and an actuator (43a, 43b) Connect to a pressing piece (37a, 37b), and fix one end of the spring (45a, 45b) on the other end (29a, 29b) to allow the movable terminal (31a, 31b) to form a swingable form .
該按鍵(5)底側連動二滑塊(61a、61b)及一押壓部(51),該二滑塊(61a、61b)一側分別以傾斜面(79a、79b)抵頂於一押壓軸(63a、63b)上相對應的傾斜面(71a、71b)上,且二滑塊(61a、61b)另分別以一他端部(77a、77b)對應於該押壓片(37a、37b)上方;而該常閉接點(7)則可經由一可動部(15)延伸至該押壓部(51)下方。 The bottom side of the button (5) is linked with two sliders (61a, 61b) and a pressing portion (51). One side of the two sliders (61a, 61b) is pressed against a pressing surface (79a, 79b) respectively. On the corresponding inclined surfaces (71a, 71b) on the pressing shafts (63a, 63b), and the two sliding blocks (61a, 61b) have other ends (77a, 77b) corresponding to the pressing pieces (37a, 37b) ) Above; and the normally closed contact (7) can be extended to the bottom of the pressing portion (51) via a movable portion (15).
操作時,當該按鍵(5)受按壓時,可連動二滑塊(61a、61b)及押壓部(51)下降,使該二滑塊(61a、61b)之他端部(77a、77b)分別推抵二押壓片(37a、37b),以經由二作動體(43a、43b)驅動二可動端子(31a、31b)由常閉固定端子(33a、33b)移至二常開固定端子(35a、35b),藉以完成第一階段由OFF改變至ON的動作。 During operation, when the button (5) is pressed, the two sliding blocks (61a, 61b) and the pressing part (51) can be moved down to make the other ends (77a, 77b) of the two sliding blocks (61a, 61b) ) Push the two pressing pieces (37a, 37b) respectively to drive the two movable terminals (31a, 31b) from the normally closed fixed terminals (33a, 33b) to the two normally open fixed terminals via the two actuators (43a, 43b) (35a, 35b), in order to complete the first phase of the action from OFF to ON.
當該按鍵(5)持續受按壓至二押壓軸(63a、63b)受阻而停止移動時,則會使二滑塊(61a、61b)經由傾斜面(79a、79b)而沿二押壓軸(63a、63b)的傾斜面(71a、71b)下滑;此時,二滑塊(61a、61b)會產生橫向滑移而使二端部(77a、77b)脫離二押壓片(37a、37b),使二押壓片(37a、37b)可分別經由彈簧(45a、45b)的彈性作用而向上回復至原位,使該二可動端子(31a、31b)隨之由常開固定端子(35a、35b)移至常閉固定端子(33a、33b),藉以完成第二階段由ON改變至OFF的動作。 When the button (5) is continuously pressed until the two pressing shafts (63a, 63b) are blocked and stop moving, the two sliders (61a, 61b) will pass through the inclined surfaces (79a, 79b) along the two pressing shafts (63a). , 63b) The inclined surface (71a, 71b) slides down; at this time, the two sliding blocks (61a, 61b) will produce lateral sliding and the two ends (77a, 77b) will be separated from the two pressing pieces (37a, 37b), The two pressing pieces (37a, 37b) can be restored to the original position upward through the elastic action of the springs (45a, 45b) respectively, so that the two movable terminals (31a, 31b) will be changed from the normally open fixed terminals (35a, 35b). ) Move to the normally closed fixed terminals (33a, 33b) to complete the second phase of changing from ON to OFF.
同時,該按鍵(5)之押壓部(51)可推頂該可動部(15),以連動該常閉接點(7)由接合改變為斷路狀態,可進一步確保上述第二階段由ON改變至OFF等切斷電源的動作,達到避免操作人員由於緊張、疲勞或誤觸等原因而造成過度緊握按壓開關,使相關機械無法及時停止而造成重大災害發生的情形。 At the same time, the pressing portion (51) of the button (5) can push the movable portion (15) to link the normally closed contact (7) to change from engaged to disconnected state, which can further ensure that the second stage is turned on Change to OFF and cut off the power to prevent the operator from overly gripping the press switch due to tension, fatigue or mistouch, so that the related machinery cannot be stopped in time and causing major disasters.
然而,上述此種結構其由於該二可動端子(31a、31b)在活動的過程中係以他端部(29a、29b)為固定支點,沿固定路徑擺動,而與該二常開固定端子(35a、35b)相接觸與脫離,因此其接觸部位係常態性保持在同一位置,由於在上述接觸與脫離的瞬間時常會於接觸部位產生電弧(火花),此種電弧(火花)如果經常發生在接觸部位的同一位置上,會造成積碳而影響該可動端子(31a、31b)與該常開固定端子(35a、35b)的導電性,嚴重者,甚至於會產生接觸不良或卡死等故障情形;如此一來,即無法在意外或緊急狀況發生時,能確保該按壓開關正常作動並發揮應有之功能。 However, the above-mentioned structure is due to the fact that the two movable terminals (31a, 31b) use the other ends (29a, 29b) as fixed fulcrums during the movement, and swing along the fixed path, and are connected to the two normally open fixed terminals ( 35a, 35b) are in contact and separated, so the contact part is kept at the same position normally. Because the arc (spark) is often generated at the contact part at the moment of the above-mentioned contact and separation, if such arc (spark) often occurs in The same position of the contact part will cause carbon deposits and affect the conductivity of the movable terminal (31a, 31b) and the normally open fixed terminal (35a, 35b). In severe cases, it may even cause poor contact or jamming. Circumstances: In this way, it is impossible to ensure that the push switch operates normally and performs its due function when an accident or emergency occurs.
