Description
本發明係有關一種微動開關，尤指一種利用複數個槓桿以進行省力切換的微動開關。 The invention relates to a micro switch, in particular to a micro switch which utilizes a plurality of levers for labor saving switching.
微動開關是一種小型開關，開關外部裝設有任一種形狀的傳動軸，其接受不同的外力以促使開關動作。微動開關的特色在於具有微小接點間距和瞬動機構，能夠以規定的移動行程和作動力量來達到機械式的開閉，故常用來檢出機器移動時的位置狀態。 The micro switch is a small switch. The switch is externally equipped with a drive shaft of any shape, which accepts different external forces to promote the switch action. The micro switch is characterized by a small contact pitch and a momentary mechanism, which can achieve mechanical opening and closing with a predetermined movement stroke and power amount, so it is often used to detect the position state when the machine moves.
習知的微動開關，請參閱中華民國第592380號公告專利案所示，其係由一上蓋與一底座組合而成，該微動開關包括有一按鈕、一共同插腳、一開路插腳以及一固定於該共同插腳的導電彈片，該導電彈片的一端受壓於該按鈕，而該導電彈片的另一端同步下移而導通該共同插腳與該開路插腳，令該微動開關產生一切換訊號。上述專利案雖可達到切換迴路的功能，但是僅靠導電彈片承受下壓力道並提供彈力，在長時間的使用下，彈片因不斷上下擺動而導致疲勞甚而斷裂，使得微動開關無法維持正常運作。 The conventional micro switch is shown in the Patent No. 592380 of the Republic of China, which is composed of an upper cover and a base. The micro switch includes a button, a common pin, an open pin and a fixed to the same. The conductive pin of the common pin, the one end of the conductive elastic piece is pressed against the button, and the other end of the conductive elastic piece is synchronously moved downward to turn on the common pin and the open pin, so that the micro switch generates a switching signal. Although the above patent case can achieve the function of the switching circuit, the conductive elastic piece only receives the lower pressure channel and provides the elastic force. Under the long-term use, the elastic piece is often broken due to the continuous up and down swing, so that the micro switch cannot maintain normal operation.
為改善前述專利案之缺失，如圖1所示，中國實用新型第CN202110987號專利案公開一種可提升按壓次數的微動開關，其包含有一外殼1、複數個設置於該外殼1的導電端子2、一彈性件3、一導電彈片4與一按鈕5，該導電彈片4設有一受該按鈕5按壓的受壓部41、一介於複數個導電彈片4之間的接觸部42，以及連接該受壓部41與該接觸部42的至少一連接肋43。該彈性件3則連接該導電彈片4與該導電端子2，令該導電彈片4常態受該彈性件3支撐。該彈性件3提供該導電彈片4支撐力，令該 導電彈片4可避免因上下擺動而導致疲勞甚而斷裂。藉由前述架構，導電彈片4的壽命能夠增加而提升微動開關所能承受的按壓次數。 In order to improve the lack of the aforementioned patents, as shown in FIG. 1, the Chinese Utility Model No. CN202110987 discloses a micro switch capable of increasing the number of presses, which comprises a casing 1 and a plurality of conductive terminals 2 disposed on the casing 1. An elastic member 3, a conductive elastic piece 4 and a button 5, the conductive elastic piece 4 is provided with a pressure receiving portion 41 pressed by the button 5, a contact portion 42 interposed between the plurality of conductive elastic sheets 4, and the connection pressure At least one connecting rib 43 of the portion 41 and the contact portion 42. The elastic member 3 is connected to the conductive elastic piece 4 and the conductive terminal 2, so that the conductive elastic piece 4 is normally supported by the elastic member 3. The elastic member 3 provides the supporting force of the conductive elastic piece 4, so that the The conductive elastic piece 4 can avoid fatigue and even break due to up and down swing. With the foregoing structure, the life of the conductive elastic piece 4 can be increased to increase the number of times the micro switch can withstand the pressing.
該前案解決了導電彈片易產生疲勞而斷裂的缺失，使微動開關的按壓次數增加。然而，該前案仍有下述尚待改進的缺點：於該微動開關的作動過程中，按鈕5下壓該受壓部41而令該接觸部42隨著向下擺動，因導電彈片4具有一定的長度與厚度，按鈕5必須施以一較大的按壓力道，才可使該接觸部42擺動足夠的幅度而往復的切換不同連通狀態。欲降低切換所需的按壓力道，減小導電彈片4的厚度係其中一種解決方案，但該方案具有導電彈片4加工困難以及減少導電彈片4壽命的缺失。此外，接觸部42與導電彈片4接觸時常通有高電流，該高電流於該接觸部42與該導電彈片4的接觸面產生高熱而造成部分接觸部42熔融而黏著於該導電彈片4，此時，使用者須提供一足以令該接觸部42脫離該導電彈片4的力道才可使微動開關維持正常運作。因此，如何在克服黏著現象的先決條件下降低切換所需的按壓力道，仍係一尚待解決的問題。 The former case solves the problem that the conductive elastic piece is prone to fatigue and breakage, and the number of pressing of the micro switch is increased. However, the prior case still has the following disadvantages to be improved: during the operation of the micro switch, the button 5 presses the pressure receiving portion 41 to cause the contact portion 42 to swing downward, because the conductive elastic piece 4 has For a certain length and thickness, the button 5 must be applied with a large pressing pressure path to allow the contact portion 42 to swing by a sufficient amplitude to reciprocally switch between different communication states. To reduce the pressing pressure required for switching, reducing the thickness of the conductive elastic piece 4 is one of the solutions, but the solution has difficulty in processing the conductive elastic piece 4 and reduces the loss of the life of the conductive elastic piece 4. In addition, when the contact portion 42 is in contact with the conductive elastic piece 4, a high current is generated, and the high current generates high heat at the contact surface of the contact portion 42 and the conductive elastic piece 4, so that the partial contact portion 42 is melted and adhered to the conductive elastic piece 4. The user must provide a force sufficient to disengage the contact portion 42 from the conductive elastic piece 4 to maintain the micro switch in normal operation. Therefore, how to reduce the pressing pressure required for switching under the preconditions for overcoming the adhesion phenomenon is still a problem to be solved.
然而，除增加微動開關的使用壽命、以及降低切換所需的按壓力道外，為製造各種不同精密度的機械，工業界對微動開關的規格要求亦大異其趣。如前所述，不同規格的微動開關具有特定的移動行程和作動力量。舉例來說，將彈片的厚度變薄即能夠降低作動力量，但該移動行程的大小牽涉到多種內部零件的組合，不可能改變單一零件即符合各種所需的規格。因此，製造商為因應不同移動行程的規格而常需開發出多種生產模具，使得生產成本的提高，因此，如何利用相同的生產模具而輕易改變微動開關的移動行程，也係一尚待解決的問題。 However, in addition to increasing the service life of the microswitch and reducing the pressure rail required for switching, the industry's specifications for microswitches are quite different for manufacturing machines of various precisions. As mentioned earlier, microswitches of different sizes have a specific movement stroke and power. For example, thinning the thickness of the shrapnel can reduce the amount of power, but the size of the travel stroke involves a combination of various internal parts, and it is impossible to change a single part to meet various required specifications. Therefore, manufacturers often need to develop a variety of production molds in response to the specifications of different moving strokes, so that the production cost is improved. Therefore, how to easily change the moving stroke of the micro-switch by using the same production mold is also to be solved. problem.
本發明之主要目的，在於降低切換所需的按壓力道，又能夠避免因黏著現象造成微動開關無法維持正常運作的缺失。 The main object of the present invention is to reduce the pressing stroke required for switching, and to avoid the lack of the micro-switch to maintain normal operation due to the adhesion phenomenon.
本發明之另一目的，在於解決因應不同微動開關規格而需開發出多種生產模具的缺失。 Another object of the present invention is to solve the need to develop a variety of production molds in response to different microswitch specifications.

透過前述之技術方案，本發明節省切換力量之微動開關相較於習知技術的特點在於： Through the foregoing technical solution, the micro switch of the present invention that saves switching power is characterized by the prior art:

請復參閱『圖4』，當按壓部21未受壓下移，該彈性元件22提供彈力推抵該受力部312向上而令該致動部313遠離該連動部322，該連動部322未受該致動部313的連動而使該傳動件32的施力部323未接觸或輕觸該作動件15的壓觸部151，此時，該作動件15的支撐部153以該共同端子12為支點而提供彈力推抵該導接部152常態連接該第一導電端子13，令該共同端子12與該第一導電端子13導通而構成一第一導電狀態。於本實施例中，該第二導電端子14為該常時閉路端子，因此，於該第一導電狀態，該微動開關並未產生一切換訊號輸出至後端的負載。 Referring to FIG. 4 , when the pressing portion 21 is not pressed down, the elastic member 22 provides an elastic force to push the force receiving portion 312 upward to move the actuating portion 313 away from the linking portion 322 , and the linking portion 322 . The urging portion 323 of the transmission member 32 is not touched or touched by the pressing portion 151 of the actuator 15 without being interlocked by the actuating portion 313. At this time, the supporting portion 153 of the actuator 15 is the common terminal. 12 is provided as a fulcrum to provide a spring force to push the guiding portion 152 to normally connect the first conductive terminal 13 , and the common terminal 12 and the first conductive terminal 13 are electrically connected to form a first conductive state. In this embodiment, the second conductive terminal 14 is the constant-time closed-circuit terminal. Therefore, in the first conductive state, the micro-switch does not generate a load for switching the signal output to the back end.
請參閱『圖5』，係本發明一實施例之作動示意圖，當該按壓部21由該原始位置受壓下移至該受壓位置，設置於該位移行程中的受力部312被該按壓部21壓掣下移而壓縮該彈性元件22，該致動部313受到該受力部312的連動而以該軸轉部311為軸點逆時鐘旋轉，進而該致動部313上移而向上推抵該連動部322，此時，該施力部323受到該連動部322的連動而以該軸轉部321為軸點順時鐘旋轉，進而壓掣該壓觸部151下移，因為該壓掣力道大於該支撐部153所提供的向下彈力，該導接部152亦跟著該壓觸部151下移，此時，該導接部152脫離該第一導電端子13而連接第二導電端子14，令該共同端子12與該第二導電端子14導通而構成一第二導電狀態。就整體觀之，該承力件31受壓於該按壓部21而具有一順時鐘旋轉的旋轉行程，而該傳動件32相對於該承力件31具有一逆時鐘旋轉的反向旋轉行程，該受力部312受壓於該按壓部21而連動該施力部323於該反向旋轉行程壓掣該壓觸部151，令該壓觸部151連動該導接部152於該第一導電狀 態與該第二導電狀態之間切換。於本實施例中，該第二導電端子14為該常時開路端子，因此，於該第二導電狀態，該微動開關將產生一切換訊號輸出至後端的負載。 Referring to FIG. 5, it is an operation diagram of an embodiment of the present invention. When the pressing portion 21 is pressed from the original position and moved to the pressed position, the force receiving portion 312 disposed in the displacement stroke is pressed. The portion 21 is pressed down to compress the elastic member 22, and the actuating portion 313 is rotated by the force receiving portion 312 to rotate counterclockwise with the shaft rotating portion 311 as an axis, and the actuating portion 313 is moved up and upward. When the interlocking portion 322 is pushed, the urging portion 323 is rotated by the interlocking portion 322 and clockwise with the shaft rotating portion 321 as a pivot point, and the pressing portion 151 is pressed downward, because the pressing portion is pressed. The force channel is greater than the downward elastic force provided by the support portion 153, and the guiding portion 152 is also moved downward with the pressure contact portion 151. At this time, the guiding portion 152 is separated from the first conductive terminal 13 to connect the second conductive terminal 14 The common terminal 12 and the second conductive terminal 14 are electrically connected to form a second conductive state. In a holistic view, the bearing member 31 is pressed against the pressing portion 21 to have a clockwise rotation, and the transmission member 32 has a reverse rotation rotation counterclockwise with respect to the bearing member 31. The force receiving portion 312 is pressed against the pressing portion 21 to interlock the pressing portion 323 to press the pressing portion 151 in the reverse rotation direction, so that the pressing portion 151 interlocks the guiding portion 152 in the first conductive shape. Switching between the state and the second conductive state. In this embodiment, the second conductive terminal 14 is the normally open terminal. Therefore, in the second conductive state, the micro switch generates a load outputted to the back end by a switching signal.
前述『圖4』與『圖5』所描述的作動機制可以運用雙槓桿原理加以理解。該承力件31作為一第一槓桿係以該軸轉部311為支點而該受力部312與該致動部313則為分別位於支點兩端的施力臂，該傳動件32作為一第二槓桿係以該軸轉部321為支點而該連動部322與該施力部323則為分別位於支點兩端的施力臂，該致動部313耦合該連動部322而令該第一槓桿與該第二槓桿可互相連動。藉由調整二槓桿的施力臂長度，使用者能夠設計出省力的微動開關。舉例來說，若該受力部312的長度遠大於該施力部323，則因為該第一槓桿與該第二槓桿互相耦合而具有相同力矩的物理原理，施加於該受力部312的力量可於該施力部323產生加乘的效果，因此，僅需以微小地力量壓掣該按壓部21，該施力部323即具有一放大的力量壓掣該壓觸部151而帶動該導接部152上下擺動，藉此，微動開關即能夠在克服黏著現象的先決條件下，順利的降低切換所需的按壓力道。 The actuation mechanism described in the above "Fig. 4" and "Fig. 5" can be understood using the principle of double lever. The bearing member 31 serves as a first lever with the shaft rotating portion 311 as a fulcrum, and the force receiving portion 312 and the actuating portion 313 are urging arms respectively located at two ends of the fulcrum, and the transmission member 32 serves as a second The lever is fulcrum with the shaft rotating portion 321 as a fulcrum, and the linking portion 322 and the urging portion 323 are urging arms respectively located at two ends of the fulcrum, and the actuating portion 313 couples the linking portion 322 to make the first lever and the first lever The two levers can be linked to each other. By adjusting the length of the arm of the two levers, the user can design a labor-saving microswitch. For example, if the length of the force receiving portion 312 is much larger than the force applying portion 323, the force applied to the force receiving portion 312 may be due to the physical principle that the first lever and the second lever are coupled to each other and have the same moment. The urging portion 323 generates an effect of multiplication. Therefore, the pressing portion 21 only needs to be pressed with a slight force. The urging portion 323 has an amplifying force to press the pressing portion 151 to drive the guiding portion 152. Swing up and down, whereby the micro switch can smoothly reduce the pressing stroke required for switching under the precondition of overcoming the sticking phenomenon.
此外，因為本發明之按壓部21係利用由該承力件31與該傳動件32所組成的驅動組30而驅使該導接部152上下擺動，該按壓部21於該通道16中的位移行程可藉由調整該驅動組30的旋轉行程而改變，而追根究底，該驅動組30的旋轉行程係取決於眾多因子，諸如：該承力件31與該傳動件32之間的距離、該承力件31之受力部312與致動部313的長度、以及該傳動件32之連動部322與該施力部323的長度，因此，欲符合各種微動開關的移動行程，製造商不需重新開模，僅需調整前述影響該旋轉行程的因子，即可製作出各種不同規格的微動開關。 In addition, since the pressing portion 21 of the present invention drives the guiding portion 152 to swing up and down by the driving group 30 composed of the bearing member 31 and the transmission member 32, the displacement stroke of the pressing portion 21 in the passage 16 The rotation of the drive group 30 can be changed by adjusting the rotation stroke of the drive group 30. The rotation of the drive group 30 depends on a plurality of factors, such as the distance between the bearing member 31 and the transmission member 32. The length of the force receiving portion 312 and the actuating portion 313 of the bearing member 31, and the length of the interlocking portion 322 of the transmission member 32 and the biasing portion 323, therefore, the manufacturer does not need to re-fit in accordance with the movement stroke of the various microswitches. To open the mold, it is only necessary to adjust the aforementioned factors affecting the rotation stroke to produce micro-switches of various specifications.
綜上所述，本發明節省切換力量之微動開關在該按壓件與該作動件之間設置有一驅動組，該驅動組包含有分別旋轉地樞設於該殼體的一承力件與至少一相對該承力件具有一反向旋轉行程的傳動件。該承力件包含有一設置於該位移行程中的受力部與一連接該受力部的致動部，該傳動件包含有一連動於該致動部的連動部以及一連接該連動部的施力部。透過前述架構，該按壓件得以利用該驅動組驅使該導接部於一第一導電狀態與一第二導電狀態之間切換。相較於習知技術，本發明運用槓桿原理設計 出可省力切換的微動開關，使本發明可利用微弱的切換力量即可達到開關切換的目的。此外，藉由任意變化驅動組的規格，製造商能夠製造出各種具有不同移動行程和作動力量的微動開關，以滿足各種特殊的使用需求。 In summary, the micro switch of the present invention saves the switching force, and a driving group is disposed between the pressing member and the actuating member, and the driving group includes a bearing member and at least one pivotally pivotally disposed on the housing. A transmission member having a reverse rotation stroke relative to the bearing member. The bearing member includes a force receiving portion disposed in the displacement stroke and an actuating portion connecting the force receiving portion, the transmission member includes a linking portion coupled to the actuating portion and a coupling portion connecting the linking portion Force department. Through the foregoing structure, the pressing member can drive the guiding portion to switch between a first conductive state and a second conductive state by using the driving group. Compared with the prior art, the invention is designed by using the principle of leverage The micro switch can be switched with labor saving, so that the invention can achieve the purpose of switching by using weak switching force. In addition, by varying the specifications of the drive group, manufacturers can create a variety of micro-switches with different travel strokes and power to meet a variety of special needs.
