Abstract
Description
本發明係有關於一種過熱斷電的開關、用電設備及其過熱斷電的方法，特別是指利用彈性件來施加彈性力於活動導電件，並利用記憶合金在溫度變化時產生的形變來改變彈性力的大小，以控制活動導電件導通通路或斷開通路的發明。 The invention relates to a switch for overheating and power-off, an electric device and a method for overheating and power-off, in particular, it refers to the use of an elastic member to apply elastic force to a movable conductive member, and the deformation of the memory alloy when the temperature changes The invention of changing the magnitude of the elastic force to control the conduction path or the break path of the movable conductive member.
習知的翹板開關是控制開關在一定角度範圍作往復式樞轉，來控制開關的通路與斷路，例如中華民國專利第560690號「切換開關之火花遮蔽構造」，在開關樞轉時，利用定位特徵將其定位在一第一位置或一第二位置來形成通路或斷路。 The conventional rocker switch is to control the switch to reciprocate pivoting at a certain angle to control the path and disconnection of the switch. For example, the Republic of China Patent No. 560690 "Sparking Structure of the Switch" is used when the switch pivots. The positioning feature positions it in a first position or a second position to form a passage or an open circuit.
習知的按壓開關，每次按壓操作可以反覆控制該開關的通路與斷路，按鈕利用了類似習知自動原子筆的往復按鈕構造，使該開關的按鈕在每次壓按時定位在下方位置或上方位置，例如中國專利第CN103441019號「按鈕開關」所揭露者。 The conventional push switch can repeatedly control the path and disconnection of the switch each time it is pressed. The button uses a reciprocating button structure similar to the conventional automatic ballpoint pen, so that the button of the switch is positioned at the lower position or each time it is pressed. The upper position, for example, is disclosed by Chinese Patent No. CN103441019 "Push Button Switch".
在中華民國專利第321352號「線上開關結構改良」揭露一種具有保險絲的開關構造，但該保險絲位在『電流傳遞必要路徑』中，保險絲需要依賴電流通過才有保護作用，特別是過載的電流才能有機會融斷該保險絲。既然保險絲在工作時需要讓電流通過，但又必須在電流過大時可以被融斷，因此常 使用低熔點的鉛錫合金、鋅作為保險絲，保險絲的電阻較大，導電性遠不如銅，但因為保險絲是位在電流傳遞必要路徑上，因此會有耗能的問題。 Republic of China Patent No. 321352 "Online Switch Structure Improvement" discloses a switch structure with a fuse, but the fuse is located in the "necessary path for current transmission". The fuse needs to rely on the passage of current for protection, especially for overload current There is an opportunity to blow the fuse. Since the fuse needs to let current flow when it is working, it must be blown when the current is too large, so it is often Low-melting lead-tin alloy and zinc are used as the fuse. The fuse has a larger resistance and is far less conductive than copper, but because the fuse is located in the necessary path for current transmission, there will be a problem of energy consumption.
在中華民國專利第M382568號「雙極自動斷電式安全開關」揭露一種雙金屬片型態的過載保護開關，但該雙金屬片同樣必須位在『電流傳遞必要路徑』中，需要依賴電流通過的熱能以產生變形，特別是需要過載的電流才能使該雙金屬片變形而中斷電路，因此同樣有耗能的問題。 In the Republic of China Patent No. M382568 "Bipolar Automatic Power-off Safety Switch", a bimetallic overload protection switch is disclosed, but the bimetallic sheet must also be located in the "necessary path for current transmission" and needs to rely on the passage of current The heat energy is deformed, especially the overloaded current is required to deform the bimetal and interrupt the circuit, so there is also the problem of energy consumption.
本案發明人因而提出中華民國發明專利申請第107123012號「開關及用電設備過熱斷電的方法」，該案採用有別於保險絲與有別於雙金屬片的斷電方法，該案的過熱破壞件不依賴電流通過執行『過載破壞』，而係藉由熱能傳遞執行『過熱破壞』並使開關斷電。但是，過熱破壞的方式是一次性使用，無法重複使用。 The inventor of the case therefore proposed the invention patent application No. 107123012 of the Republic of China "Method of overheating and power-off of switches and electrical equipment". The case adopts a power-off method different from fuses and a bimetal, and the case of overheating damage The device does not rely on current to perform "overload destruction", but performs "overheat destruction" through thermal energy transfer and turns off the switch. However, the method of overheating destruction is one-time use and cannot be reused.

The memory alloy (6A) can change shape at a memory temperature when an operating temperature is lower than the memory temperature , The memory alloy (6A) has a first shape, when the working temperature is higher than the memory temperature, The memory alloy (6A) has a second shape. In the field of overheating and power-off switches, the memory alloy (6A) can be made of a material with a memory temperature between 80°C and 300°C. The memory temperature in this embodiment Take 140°C as an example. The memory alloy (6A) is first placed in the containing tube portion (52A), the first elastic member (7A) is stacked to contact the memory alloy (6A), and the thermally conductive shell member (53A) movably penetrates into the Accommodating the tube portion (52A) against the first elastic member (7A), so that the first elastic member (7A) is compressed and restricted between the memory alloy (6A) and the thermally conductive shell member (53A), Then, a first elastic force is applied to the rocker conductive member (4A). In the closed state of the rocker switch, the first elastic force causes the rocker conductive member (4A) not to contact the first conductive member (2A) and the second conductive member (3A) at the same time to form a current interruption, At this time, the working temperature is lower than the memory temperature, and the memory alloy (6A) assumes the first shape.
本實施例的翹板開關進一步有一第二彈性件(8A)，該第二彈性件(8A)在本實施例係一彈簧，該第二彈性件(8A)具有一第二彈性力，該第二彈性力直接作用於該操作件(5A)，使該操作件(5A)趨向該關閉狀態。 The rocker switch of this embodiment further has a second elastic member (8A). The second elastic member (8A) is a spring in this embodiment. The second elastic member (8A) has a second elastic force. Two elastic forces directly act on the operating member (5A), so that the operating member (5A) tends to the closed state.
參閱第三圖所示，使用者藉由操作該操作件(5A)繞著該樞接點(51A)旋動，使該導熱殼件(53A)在該翹板導電件(4A)上滑移，驅使該翹板導電件(4A)以翹板運動型態而選擇式地接觸或分離於該第二導電件(3A)。當該導熱殼件(53A)在該翹板導電件(4A)上朝向該翹板導電件(4A)上之一銀接點(41A)的方向滑移，該第一彈性力將迫使該銀接點(41A)接觸該第二導電件(3A)，且上述第二彈性力不足以將該操作件(5A)推動至該關閉狀態，此時翹板開關成為一開啟狀態，形成一電流通路。 As shown in the third figure, the user rotates the operating member (5A) around the pivot point (51A) to slide the heat conductive shell member (53A) on the rocker conductive member (4A) , Driving the rocker conductive member (4A) to selectively contact or separate from the second conductive member (3A) in a rocker movement pattern. When the thermally conductive shell member (53A) slides on the rocker conductive member (4A) toward a silver contact (41A) on the rocker conductive member (4A), the first elastic force will force the silver The contact (41A) contacts the second conductive member (3A), and the second elastic force is insufficient to push the operating member (5A) to the closed state, and the rocker switch becomes an open state, forming a current path .
參閱第四圖所示，當該第一導電件(2A)或該第二導電件(3A)所連接的外部導電設備有異常之狀態，例如外部導電設備為插座，則當插頭的金屬插腳與插座之間存有氧化物、灰塵、金屬插腳***不完全、金屬插腳變形等現 象，都會使插座的導電部位產生較大的熱能，該熱能經由該第一導電件(2A)或該第二導電件(3A)傳遞至翹板導電件(4A)，再經由該導熱殼件(53A)、該第一彈性件(7A)而傳遞至該記憶合金(6A)，該記憶合金(6A)吸收該熱能而逐漸升溫，當該記憶合金(6A)升溫至等於或高於該記憶溫度140℃時，記憶合金(6A)即變形為該第二形狀，在本實施例中，該記憶合金(6A)由該第一形狀變形為該第二形狀時，呈現收縮的型態，因此該第一彈性件(7A)會伸長，使該第一彈性力減小或喪失。 Referring to the fourth figure, when the external conductive device connected to the first conductive member (2A) or the second conductive member (3A) has an abnormal state, for example, the external conductive device is a socket, when the metal pin of the plug is There are oxides, dust, incomplete insertion of metal pins, deformation of metal pins, etc. between sockets Like this, the conductive parts of the socket will generate greater heat energy, which is transferred to the rocker conductive member (4A) through the first conductive member (2A) or the second conductive member (3A), and then through the thermally conductive shell member (53A), the first elastic member (7A) is transferred to the memory alloy (6A), the memory alloy (6A) absorbs the thermal energy and gradually heats up, when the memory alloy (6A) heats up to be equal to or higher than the memory At a temperature of 140°C, the memory alloy (6A) deforms into the second shape. In this embodiment, the memory alloy (6A) shrinks from the first shape to the second shape. The first elastic member (7A) will elongate, so that the first elastic force is reduced or lost.
在本實施例中，該第一導電件(2A)與該第二導電件(3A)的排列方向定義為一縱向，該操作件(5A)在該縱向上具有一長度，該記憶合金(6A)與該第一彈性件(7A)設置於該長度的一中央位置，該第二彈性件(8A)在該長度的設置位置與該中央位置係相距有一距離。因此當該第一彈性力減小或喪失時，該第二彈性力作用在該操作件(5A)的力矩可以使該操作件(5A)以該樞接點(51A)為軸心旋動，並帶動該導熱殼件(53A)在該翹板導電件(4A)上滑移，因而迫使該操作件(5A)移動到關閉的位置，該翹板導電件(4A)的銀接點(41A)因此脫離該第二導電件(3A)，形成斷電狀態，藉此達到過熱保護的作用。在斷電狀態下，過熱的工作溫度會逐漸下降，當工作溫度低於該記憶溫度140℃時，記憶合金(6A)恢復成第二圖與第三圖所示的第一形狀，使翹板開關又可以自由切換至開啟狀態與關閉狀態。 In this embodiment, the arrangement direction of the first conductive member (2A) and the second conductive member (3A) is defined as a longitudinal direction, the operating member (5A) has a length in the longitudinal direction, and the memory alloy (6A ) And the first elastic member (7A) are arranged at a central position of the length, and the second elastic member (8A) is arranged at a distance from the central position at the length of the installation position. Therefore, when the first elastic force is reduced or lost, the moment of the second elastic force acting on the operating member (5A) can cause the operating member (5A) to rotate around the pivot point (51A), And drive the heat conductive shell (53A) to slide on the rocker conductive member (4A), thus forcing the operating member (5A) to move to the closed position, the silver contact (41A) of the rocker conductive member (4A) ) Therefore, it separates from the second conductive member (3A) to form a power-off state, thereby achieving the effect of overheating protection. In the power-off state, the overheated working temperature will gradually decrease. When the working temperature is lower than the memory temperature of 140 ℃, the memory alloy (6A) will return to the first shape shown in the second and third figures, so that the rocker The switch can be freely switched to the open state and the closed state.

The memory alloy (6B) can change shape at a memory temperature, and when the operating temperature is lower than the memory temperature The memory alloy (6B) has a first shape, and when the operating temperature is equal to or higher than the memory temperature, the memory alloy (6B) has a second shape. In the field of overheated power-off switches, the memory alloy (6B) can be made of a material with a memory temperature between 80°C and 300°C. The memory temperature in this embodiment is 140°C as an example. The memory alloy (6B) is first placed in the containing tube portion (51B), and the first elastic member (7B) is stacked on the memory alloy (6B). The supporting heat conducting member (52B) has a limiting post (521B) and a supporting base (522B), the limiting post (521B) extends into one end of the first elastic member (7B), so that the first elastic member (7B ) Against the support base (522B), the support base (522B) and contact the cantilever conductive member (4B), so that the first elastic member (7B) is compressed and limited to the memory alloy (6B) and the Between the heat conducting parts (52B) A first elastic force is exerted on the cantilever conductive member (4B). In the closed state of pressing the switch, the first elastic force causes the cantilever conductive member (4B) to not contact the first conductive member (2B) at the same time With the second conductive member (3B), a current disconnection is formed. At this time, the operating temperature is lower than the memory temperature, and the memory alloy (6B) assumes the first shape.
本實施例之該壓按開關進一步有一第二彈性件，該第二彈性件係一簧片(8B)，且該第一導電件(2B)、該簧片(8B)與該懸臂導電件(4B)三者係一體成形，該簧片(8B)具有一第二彈性力，該第二彈性力能間接作用於該操作件(5B)中的容置管部(51B)，也使該懸臂導電件(4B)趨向該關閉狀態。 The push switch of this embodiment further has a second elastic member, the second elastic member is a reed (8B), and the first conductive member (2B), the reed (8B) and the cantilever conductive member ( 4B) The three parts are integrally formed, the reed (8B) has a second elastic force, which can act indirectly on the accommodating tube portion (51B) in the operating member (5B), and also makes the cantilever The conductive member (4B) tends to this closed state.
參閱第六圖所示，使用者藉由操作該操作件(5B)相對位移於該凸出部(12B)，猶如自動原子筆的按鈕一般，而使該懸臂導電件(4B)選擇式地接觸或分離於該第二導電件(3B)。當該操作件(5B)朝向懸臂導電件(4B)位移並定位，該支撐導熱件(52B)的支撐座(522B)將壓按該懸臂導電件(4B)靠近一銀接點(41B)的位置，使該懸臂導電件(4B)接觸該第二導電件(3B)而成為一開啟狀態，以形成一電流通路，此時該第一彈性件(7B)係進一步再被壓縮。 Referring to the sixth figure, the user can make the cantilever conductive member (4B) contact selectively by operating the operating member (5B) to displace relative to the protruding portion (12B) like a button of an automatic ballpoint pen Or separate from the second conductive member (3B). When the operating member (5B) is displaced and positioned towards the cantilever conductive member (4B), the support base (522B) supporting the heat conductive member (52B) will press the cantilever conductive member (4B) close to a silver contact (41B) At this position, the cantilever conductive member (4B) contacts the second conductive member (3B) to become an open state to form a current path, and then the first elastic member (7B) is further compressed.
參閱第七圖所示，當該第一導電件(2B)或該第二導電件(3B)所連接的外部導電設備有異常之狀態，例如外部導電設備為插座，則當插頭的金屬插腳與插座之間存有氧化物、灰塵、金屬插腳***不完全、金屬插腳變形等，都會使插座的導電部位產生較大的熱能，該熱能經由該第一導電件(2B)或該第二導電件(3B)傳遞至該懸臂導電件(4B)，再經由該支撐導熱件(52B)的支撐座(522B)、限位柱(521B)以及該第一彈性件(7B)而傳遞至該記憶合金(6B)，該記憶合金(6B)吸收該熱能而逐漸升溫，當該記憶合金(6B)升溫至等於或高於該記憶溫度140℃時，記憶合金(6B)即變形為該第二形狀。在本實施例中，該記憶合金 (6B)由該第一形狀變形為該第二形狀時，呈現收縮的型態，因此該第一彈性件(7B)會伸長，使該第一彈性力減小或喪失，而在此狀態下該簧片(8B)之第二彈性力將會大於該第一彈性力，因而迫使該懸臂導電件(4B)復位，使該懸臂導電件(4B)的銀接點(41B)脫離該第二導電件(3B)，形成一斷電狀態，藉此達到過熱保護的作用。在斷電狀態下，過熱的工作溫度會逐漸下降，當工作溫度低於該記憶溫度140℃時，記憶合金(6B)恢復成第五圖與第六圖所示的第一形狀，使壓按開關又可以自由切換至開啟狀態與關閉狀態。 Referring to the seventh figure, when the external conductive device connected to the first conductive member (2B) or the second conductive member (3B) has an abnormal state, for example, the external conductive device is a socket, when the metal pin of the plug is There are oxides, dust, incomplete insertion of metal pins, deformation of metal pins, etc. between the sockets, which will cause greater heat energy to the conductive parts of the sockets. The heat energy passes through the first conductive member (2B) or the second conductive member (3B) is transferred to the cantilever conductive member (4B), and then transferred to the memory alloy through the support base (522B), the limit post (521B) and the first elastic member (7B) supporting the heat conductive member (52B) (6B), the memory alloy (6B) absorbs the thermal energy and gradually heats up, and when the memory alloy (6B) heats up to 140°C or higher than the memory temperature, the memory alloy (6B) is deformed into the second shape. In this embodiment, the memory alloy (6B) When deformed from the first shape to the second shape, it assumes a contracted shape, so the first elastic member (7B) will stretch to reduce or lose the first elastic force, and in this state The second elastic force of the reed (8B) will be greater than the first elastic force, thus forcing the cantilever conductive member (4B) to reset, so that the silver contact (41B) of the cantilever conductive member (4B) is separated from the second The conductive member (3B) forms a power-off state, thereby achieving overheating protection. In the power-off state, the overheated working temperature will gradually decrease. When the working temperature is lower than the memory temperature of 140 ℃, the memory alloy (6B) returns to the first shape shown in the fifth and sixth figures, so that the pressing The switch can be freely switched to the open state and the closed state.

參閱第九圖所示，使用者藉由操作該操作件(5C)繞著該樞接點(51C)旋動，使該導熱殼件(53C)在該翹板導電件(4C)上滑移，驅使該翹板導電件(4C)以翹板運動型態而選擇式地接觸或分離於該第二導電件(3C)。當該導熱殼件(53C)在該翹板導電件(4C)上朝向該翹板導電件(4C)上之一銀接點(41C)的方向滑移，該第一彈性力將迫使該銀接點(41C)接觸該第二導電件(3C)，且上述第二彈性力不足以將該操作件(5C)推動至該關閉狀態，此時翹板開關成為一開啟狀態，以形成一電流通路。 As shown in the ninth figure, the user rotates the operation member (5C) around the pivot point (51C) to slide the heat conductive shell member (53C) on the rocker conductive member (4C) , Driving the rocker conductive member (4C) to selectively contact or separate from the second conductive member (3C) in a rocker movement pattern. When the thermal conductive shell (53C) slides on the rocker conductive member (4C) toward a silver contact (41C) on the rocker conductive member (4C), the first elastic force will force the silver The contact (41C) contacts the second conductive member (3C), and the second elastic force is not enough to push the operating member (5C) to the closed state, at which time the rocker switch becomes an open state to form a current path.
參閱第十圖所示，當該第一導電件(2C)或該第二導電件(3C)所連接的外部導電設備有異常之狀態，例如外部導電設備為插座，則當插頭的金屬插腳與插座之間存有氧化物、灰塵、金屬插腳***不完全、金屬插腳變形等現象，都會使插座的導電部位產生較大的熱能，該熱能經該第一導電件(2C)或該第二導電件(3C)傳遞至該翹板導電件(4C)，再經由該導熱殼件(53C)、該第二彈簧(72C)而傳遞至該記憶合金(6C)，該記憶合金(6C)吸收該熱能而逐漸升溫，當該記憶合金(6C)升溫至等於或高於該記憶溫度140℃時，記憶合金(6C)即變形為該第二形狀，在本實施例中，該記憶合金(6C)由該第一形狀變形為該第二形狀時，呈現收縮的型態，因此該第一彈簧(71C)及該第二彈簧(72C)會伸長，使該第一彈性力減小或喪失。 Referring to the tenth figure, when the external conductive device connected to the first conductive member (2C) or the second conductive member (3C) has an abnormal state, for example, the external conductive device is a socket, when the metal pin of the plug is There are oxides, dust, incomplete insertion of metal pins, deformation of metal pins, etc. between the sockets, which will cause greater heat energy to the conductive parts of the socket. The heat energy passes through the first conductive member (2C) or the second conductive The component (3C) is transferred to the rocker conductive member (4C), and then transferred to the memory alloy (6C) through the thermally conductive shell member (53C) and the second spring (72C), and the memory alloy (6C) absorbs the The heat energy gradually heats up. When the memory alloy (6C) heats up to 140°C or higher than the memory temperature, the memory alloy (6C) deforms to the second shape. In this embodiment, the memory alloy (6C) When the first shape is deformed into the second shape, it assumes a contracted shape. Therefore, the first spring (71C) and the second spring (72C) are elongated, so that the first elastic force is reduced or lost.
在本實施例中，該第一導電件(2C)與該第二導電件(3C)的排列方向定義為一縱向，該操作件(5C)在該縱向上具有一長度，該記憶合金(6C)與該第一彈性件(7C)設置於該長度的一中央位置，該第二彈性件(8C)在該長度的設置位置與該中央位置係相距有一距離。因此當該第一彈性力減小或喪失時，該第二彈性力作用在該操作件(5C)的力矩可以使該操作件(5C)以該樞接點(51C) 為軸心旋動，並帶動該導熱殼件(53C)在該翹板導電件(4C)上滑移，因而迫使該操作件(5C)移動到關閉的位置，該翹板導電件(4C)的銀接點(41C)因此脫離該第二導電件(3C)，形成斷電狀態，藉此達到過熱保護的作用。在斷電狀態下，過熱的工作溫度會逐漸下降，當工作溫度低於該記憶溫度140℃時，記憶合金(6C)恢復成第八圖與第九圖所示的第一形狀，使翹板開關又可以自由切換至開啟狀態與關閉狀態。 In this embodiment, the arrangement direction of the first conductive member (2C) and the second conductive member (3C) is defined as a longitudinal direction, the operating member (5C) has a length in the longitudinal direction, and the memory alloy (6C ) And the first elastic member (7C) are disposed at a central position of the length, and the second elastic member (8C) is disposed at a distance from the central position at the length of the central position. Therefore, when the first elastic force is reduced or lost, the moment of the second elastic force acting on the operating member (5C) can make the operating member (5C) take the pivot point (51C) Rotate for the axis, and drive the heat conductive shell (53C) to slide on the rocker conductive member (4C), thus forcing the operating member (5C) to move to the closed position, the rocker conductive member (4C) The silver contact (41C) is thus detached from the second conductive member (3C), forming a power-off state, thereby achieving overheating protection. In the power-off state, the overheated operating temperature will gradually decrease. When the operating temperature is lower than the memory temperature of 140 ℃, the memory alloy (6C) will return to the first shape shown in the eighth and ninth figures, so that the rocker The switch can be freely switched to the open state and the closed state.

本實施例之該翹板開關進一步有一記憶合金(6E)及一第一彈性件(7E)，該記憶合金(6E)在一記憶溫度下能改變形狀，當一工作溫度低於該記憶溫度時，該記憶合金(6E)具有一第一形狀，在該工作溫度高於該記憶溫度時，該記憶合金(6E)具有一第二形狀，在過熱斷電的開關的領域中，該記憶合金(6E)可選用記憶溫度介於80℃至300℃之間的材質，本實施例的記憶溫度以140℃為例。該第一彈性件(7E)先置入該容置管部(52E)中，該記憶合金(6E)再疊置在該第一彈性件(7E)上，該導熱殼件(53E)活動地穿入該容置管部(52E)而頂抵該記憶 合金(6E)，該第一彈性件(7E)因而被壓縮，而產生一第一彈性力施加在該翹板導電件(4E)上。在翹板開關的關閉狀態下，該第一彈性力使該翹板導電件(4E)不同時接觸該第一導電件(2E)與該第二導電件(3E)，以形成一電流斷路，此時工作溫度低於該記憶溫度，該記憶合金(6E)呈現該第一形狀。 The rocker switch of this embodiment further has a memory alloy (6E) and a first elastic member (7E). The memory alloy (6E) can change shape at a memory temperature when an operating temperature is lower than the memory temperature , The memory alloy (6E) has a first shape, when the operating temperature is higher than the memory temperature, the memory alloy (6E) has a second shape, in the field of overheating and power-off switches, the memory alloy (6 6E) A material with a memory temperature between 80°C and 300°C can be selected. The memory temperature in this embodiment is 140°C as an example. The first elastic member (7E) is first placed in the accommodating tube portion (52E), the memory alloy (6E) is stacked on the first elastic member (7E), and the thermally conductive shell member (53E) is movable Penetrate the accommodating tube (52E) against the memory Alloy (6E), the first elastic member (7E) is thus compressed, and a first elastic force is exerted on the rocker conductive member (4E). In the closed state of the rocker switch, the first elastic force causes the rocker conductive member (4E) not to contact the first conductive member (2E) and the second conductive member (3E) at the same time to form a current interruption, At this time, the working temperature is lower than the memory temperature, and the memory alloy (6E) assumes the first shape.
本實施例的翹板開關進一步有一第二彈性件(8E)，該第二彈性件(8E)在本實施例係一彈簧，該第二彈性件(8E)具有一第二彈性力，該第二彈性力作用於該操作件(5E)，使該操作件(5E)趨向該關閉狀態。 The rocker switch of this embodiment further has a second elastic member (8E). The second elastic member (8E) is a spring in this embodiment. The second elastic member (8E) has a second elastic force. Two elastic forces act on the operating member (5E), so that the operating member (5E) tends to the closed state.
參閱第十五圖所示，使用者藉由操作該操作件(5E)繞著該樞接點(51E)旋動，使該導熱殼件(53E)在該翹板導電件(4E)上滑移，驅使該翹板導電件(4E)以翹板運動型態而選擇式地接觸或分離於該第二導電件(3E)。當該導熱殼件(53E)在該翹板導電件(4E)上朝向該翹板導電件(4E)上之一銀接點(41E)的方向滑移，該第一彈性力將迫使該銀接點(41E)接觸該第二導電件(3E)，且上述第二彈性力不足以將該操作件(5A)推動至該關閉狀態，此時翹板開關成為一開啟狀態，形成一電流通路。 Referring to the fifteenth figure, the user rotates the operating member (5E) around the pivot point (51E) to slide the heat conductive shell member (53E) on the rocker conductive member (4E) Moving, driving the rocker conductive member (4E) to selectively contact or separate from the second conductive member (3E) in a rocker movement pattern. When the thermally conductive shell member (53E) slides on the rocker conductive member (4E) toward a silver contact (41E) on the rocker conductive member (4E), the first elastic force will force the silver The contact (41E) contacts the second conductive member (3E), and the second elastic force is insufficient to push the operating member (5A) to the closed state, at which time the rocker switch becomes an open state, forming a current path .
參閱第十六圖所示，當該第一導電件(2E)或該第二導電件(3E)所連接的外部導電設備有異常之狀態，例如外部導電設備為插座，則當插頭的金屬插腳與插座之間存有氧化物、灰塵、金屬插腳***不完全、金屬插腳變形等現象，都會使插座的導電部位產生較大的熱能，該熱能經由該第一導電件(2E)或該第二導電件(3E)傳遞至翹板導電件(4E)，再經由該導熱殼件(53E)而傳遞至該記憶合金(6E)，該記憶合金(6E)吸收該熱能而逐漸升溫，當該記憶合金(6E)升溫至等於或高於該記憶溫度140℃時，記憶合金(6E)即變形為該第二形狀，在 本實施例中，該記憶合金(6E)由該第一形狀變形為該第二形狀時，呈現收縮的型態，因此該第一彈性件(7E)會伸長，使該第一彈性力減小或喪失。 Referring to the sixteenth figure, when the external conductive device connected to the first conductive member (2E) or the second conductive member (3E) has an abnormal state, for example, the external conductive device is a socket, when the metal pin of the plug There are oxides, dust, incomplete insertion of metal pins, deformation of metal pins, etc. between the socket and the conductive parts of the socket, which will generate greater thermal energy. The thermal energy passes through the first conductive member (2E) or the second The conductive member (3E) is transferred to the rocker conductive member (4E), and then transferred to the memory alloy (6E) through the thermally conductive shell member (53E). The memory alloy (6E) absorbs the thermal energy and gradually heats up. When the temperature of the alloy (6E) is equal to or higher than the memory temperature of 140°C, the memory alloy (6E) is deformed into the second shape. In this embodiment, when the memory alloy (6E) is deformed from the first shape to the second shape, it assumes a contracted shape, so the first elastic member (7E) will elongate, reducing the first elastic force Or lost.
在本實施例中，該第一導電件(2E)與該第二導電件(3E)的排列方向定義為一縱向，該操作件(5E)在該縱向上具有一長度，該記憶合金(6E)與該第一彈性件(7E)設置於該長度的一中央位置，該第二彈性件(8E)在該長度的設置位置與該中央位置係相距有一距離。因此當該第一彈性力減小或喪失時，該第二彈性力作用在該操作件(5E)的力矩可以使該操作件(5E)以該樞接點(51E)為軸心旋動，並帶動該導熱殼件(53E)在該翹板導電件(4E)上滑移，因而迫使該操作件(5E)移動到關閉的位置，該翹板導電件(4E)的銀接點(41E)因此脫離該第二導電件(3E)，形成斷電狀態，藉此達到過熱保護的作用。在斷電狀態下，過熱的工作溫度會逐漸下降，當工作溫度低於該記憶溫度140℃時，記憶合金(6E)恢復成第十四圖與第十五圖所示的第一形狀，使翹板開關又可以自由切換至開啟狀態與關閉狀態。 In this embodiment, the arrangement direction of the first conductive member (2E) and the second conductive member (3E) is defined as a longitudinal direction, the operating member (5E) has a length in the longitudinal direction, and the memory alloy (6E ) And the first elastic member (7E) are disposed at a central position of the length, and the second elastic member (8E) is disposed at a distance from the central position at the length of the central position. Therefore, when the first elastic force is reduced or lost, the moment of the second elastic force acting on the operating member (5E) can cause the operating member (5E) to rotate around the pivot point (51E) as the axis, And drive the heat conductive shell (53E) to slide on the rocker conductive member (4E), thus forcing the operating member (5E) to move to the closed position, the silver contact (41E) of the rocker conductive member (4E) ) Therefore, the second conductive member (3E) is detached to form a power-off state, thereby achieving the function of overheat protection. In the power-off state, the overheated working temperature will gradually decrease. When the working temperature is lower than the memory temperature by 140°C, the memory alloy (6E) will return to the first shape shown in Figure 14 and Figure 15, so that The rocker switch can be freely switched to the open state and the closed state.

The rocker switch of this embodiment further has a first elastic member (7F), the first elastic member (7F) is placed in the accommodating tube portion (52F), and the thermally conductive shell member (53F) penetrates movably The accommodating tube portion (52F) abuts against the first elastic member (7F). It should be particularly noted that, in this embodiment, the first elastic member (7F) is made of memory alloy. A second elastic member (8F) exerts a second elastic force on the operating member (5F).
據此，本實施例的第一彈性件(7F)採用記憶合金，直接由該第一彈性件的變形來改變該第一彈性力的大小，同樣可達到過熱斷電的效果。 According to this, the first elastic member (7F) of this embodiment adopts a memory alloy, and the magnitude of the first elastic force is directly changed by the deformation of the first elastic member, and the effect of overheating and power-off can also be achieved.
