The deformation occurs and the first contact 131 is separated from the second contact 121 to form an open circuit (OFF), thereby forming a form of the current overload protection switch 10. This type of patent is found in patents 540811, 367091, 320335, 262168, 208384, etc. in China.
惟查，上述習用過載保護開關10，係針對電流過載所設計之結構，但是，對於突波或雷擊等突發狀況，而造成電壓瞬間過載，並無自動斷路（OFF）的保護裝置，因此易對電器用品造成損害或使用上有安全之虞。However, the above-mentioned conventional overload protection switch 10 is a structure designed for current overload. However, for sudden situations such as sudden waves or lightning strikes, the voltage is instantaneously overloaded, and there is no automatic open circuit (OFF) protection device. Damage to electrical appliances or safety in use.
是以，為了使用上安全，在諸多的電路中，習用過載保護開關10在使用時，係另外再並接一突波吸收器(壓敏電阻(Metal Oxide Varistor) 及主電源串接一溫度保險絲，俾防止過電壓時所造成的損害。Therefore, in order to be safe in use, in many circuits, the conventional overload protection switch 10 is additionally connected to a surge absorber (Metal Oxide Varistor and main power supply in series with a thermal fuse). , 俾 to prevent damage caused by overvoltage.
如圖2A、圖2B及圖2C所示，即為習用一種溫度保險絲的結構形態，其主要是於一端為開口的外殼20內，尾端置入感溫元件21，並蓋置一擋片22，隨即置入一第一長距彈簧23，再蓋置一擋片24後將導電片25置入，該導電片25是由一圓板狀本體於環邊形成複數個向上弧狀延伸的導電爪片，利用各爪片與外殼20內壁導電面觸靠，另外將銅製之前導桿201一端插置於陶瓷製之絕緣的內襯套27內而由扣環28將其卡固並露出一小段，再於內襯套27一端套置一第二長距彈簧26後置入外殼20內，使前導桿201與第二彈簧26皆抵靠導電片25之本體面，此時導電片25將位移至第一長距彈簧與第二長距彈簧左右彈力保持平衡的位置，隨即於外露在外殼10外的前導桿201，套置一外襯套29並以絕緣的黏合劑將外殼10開口封閉，同時讓內襯套27與外襯套29接合成一體形態，最後將後導桿202一端以鉚合固接於外殼20另一端上。此種溫度保險絲的使用形態如圖2B及圖2C所示，利用前導桿201與後導桿202將溫度保險絲接設於電源導線上，電源由後導桿202經外殼20傳導至導電片24再傳導至與導電片24觸靠之前導桿201而讓電源形成導通狀態，當環境溫度高於預設溫度時，其中之感溫元件21會瞬間熔化，此時第一長距彈簧23會向感溫元件21方向伸張頂推銅片22移位，使熔化的感溫元件21由銅片22邊緣流出，而第二長距彈簧26與第一長距彈簧23之間的平衡固定力遭到破壞，使得第二彈簧26將導電片25向感溫元件21方向滑動推移，由於前導桿201固接於內襯套27而無法移動，因此移位後之導電片25與前導桿201形成分離而無接觸狀態，使電源無法傳導至後導桿202而形成斷電，以避免電器產品損毀而達到保險的功效。此類型專利見諸於我國公告第370479、M395243號等專利中。As shown in FIG. 2A, FIG. 2B and FIG. 2C, a structural form of a conventional thermal fuse is mainly used in the outer casing 20 having an opening at one end, and the temperature sensing element 21 is placed at the tail end, and a blocking piece 22 is placed thereon. Then, a first long-distance spring 23 is placed, and then a stopper 24 is placed to insert the conductive sheet 25, and the conductive sheet 25 is formed by a disc-shaped body on the side of the ring to form a plurality of conductive claws extending upwardly. The sheet is used to contact the conductive surface of the inner wall of the outer casing 20, and one end of the copper front guide rod 201 is inserted into the ceramic inner bushing 27 and is fastened by the buckle 28 to expose a small section. Then, a second long-distance spring 26 is placed on one end of the inner bushing 27 and placed in the outer casing 20, so that the front guiding rod 201 and the second spring 26 abut against the body surface of the conductive sheet 25, and the conductive sheet 25 will be displaced. The position of the first long-distance spring and the second long-distance spring are balanced, and then the front guiding rod 201 exposed outside the outer casing 10 is sleeved with an outer bushing 29 and the outer casing 10 is closed by an insulating adhesive. At the same time, the inner bushing 27 and the outer bushing 29 are joined into an integrated form, and finally the end of the rear guide rod 202 is riveted. 20 connected to the other end of the housing. As shown in FIG. 2B and FIG. 2C, the temperature fuse is connected to the power supply lead by the front guide 201 and the rear guide 202, and the power is transmitted from the rear guide 202 to the conductive sheet 24 via the outer casing 20. Conducted to the conductive rod 24 before the conductive rod 24 to make the power supply into a conductive state, when the ambient temperature is higher than the preset temperature, wherein the temperature sensing element 21 will melt instantaneously, at this time, the first long-distance spring 23 will feel The temperature element 21 is displaced in the direction of the pushing of the copper piece 22, so that the molten temperature sensing element 21 flows out from the edge of the copper piece 22, and the balanced fixing force between the second long distance spring 26 and the first long distance spring 23 is broken. The second spring 26 slides the conductive piece 25 toward the temperature sensing element 21, and the front guide bar 201 is fixed to the inner bushing 27 and cannot move. Therefore, the displaced conductive piece 25 is separated from the front guide bar 201 without The contact state prevents the power source from being transmitted to the rear guide bar 202 to form a power failure, so as to prevent the electrical product from being damaged and achieving the safety effect. This type of patent is found in patents such as China's Announcement Nos. 370479 and M395243.
惟查，上述 習用過載保護開關10外接溫度保險絲20及突波吸收器(壓敏電阻) (Metal Oxide Varistor) 的方式，雖然可達過電流及過電壓的雙重保護功能，但外接突波吸收器及溫度保險絲之間，需做緊靠之間接導熱包覆，其耐熱包覆方法與管狀溫度保險絲與平面突波吸收器間的點或線接觸面大小，影響是否能夠快速反應作動及傳導失敗後產生持續加熱之危險，且銲接時需加長與外殼20間導熱遮蔽距離，防管狀溫度保險絲外殼20過熱提前熔解斷路，因而需加大空間方式因應，徒增加工配設與組裝上的不便，也造成電器產品可靠度及安全上的問題。However, the above-mentioned conventional overload protection switch 10 is externally connected with the thermal fuse 20 and the oscillating absorber (Metal Oxide Varistor). Although it can achieve the double protection function of overcurrent and overvoltage, the external surge absorber Between the thermal fuse and the thermal fuse, the heat-resistant coating method and the point or line contact surface between the tubular temperature fuse and the planar surge absorber affect the rapid reaction and conduction failure. There is a danger of continuous heating, and the heat conduction shielding distance between the outer casing and the outer casing 20 needs to be lengthened during welding. The anti-tubular temperature fuse casing 20 is overheated and melted and disconnected in advance, so that the space mode is required to be increased, and the inconvenience of assembling and assembling is increased. Causes reliability and safety of electrical products.
圖2D係習用一種防突波(雷擊)斷路方式， 其係將突波吸收器101與溫度保險絲102利用熱縮套管103縮合緊束或用彈性膠圈彈性緊束，使平面的突波吸收器101遇雷擊時快速升溫達到中溫段且未達高溫段時，間接傳熱至管狀的溫度保險絲102內的『快速』熔化體即時作動，而使主電源斷路。但其若表面接觸不良，則因傳熱緩慢而遞延了中斷主電源的作動時間，使突波吸收器101溫度繼續上升達到高溫段，此時熱縮套管103破裂失去緊束突波吸收器101與溫度保險絲102之束力，便停止了熱傳導，而使突波吸收器101昇至高溫熔融而燒毀。由於只有點或線的接觸，有時亦會因為表面髒汙產生接觸不良情形，使管制主電源斷路之溫度保險絲102不作動斷路功能，而使突波吸收器101昇至高溫炙熱而燒毀。此二項為使用此方式品管可靠度無法確保的難處。FIG. 2D is a conventional anti-surge (lightning strike) breaking method, in which the surge absorber 101 and the thermal fuse 102 are condensed tightly by the heat shrinkable sleeve 103 or elastically bundled with an elastic rubber ring to absorb the plane surge. When the device 101 rapidly rises to reach the middle temperature section in the event of a lightning strike and does not reach the high temperature section, the "fast" melt which indirectly transfers heat to the tubular temperature fuse 102 acts immediately, and the main power source is disconnected. However, if the surface contact is poor, the operation time of interrupting the main power source is delayed due to the slow heat transfer, so that the temperature of the surge absorber 101 continues to rise to a high temperature range, at which time the heat shrinkable sleeve 103 is broken and the tight burst is absorbed. The force of the device 101 and the thermal fuse 102 stops the heat conduction, and the surge absorber 101 is raised to a high temperature to be melted and burned. Since there is only a point or line contact, the contact frit may be caused by the surface contamination, and the temperature fuse 102 that regulates the main power supply disconnection does not act to open the circuit, and the surge absorber 101 is raised to a high temperature and burned. These two items are difficult to ensure the reliability of the quality control using this method.
圖2E係習用另一種防突波(雷擊)斷路方式，其係利用一彈力膠圈103將突波吸收器101與兩片彈力導電接觸片104彈性束緊，使主電源因而接觸導通。當突波收器101遇雷擊於微秒間發熱至高溫段，此時彈力膠圈103會”慢速”熔斷，而使兩彈力接觸片104彈性分離主電源形成斷路。此時彈力膠圈103受突波吸收器101高溫而燃燒，但因封閉在一防火之密封空間100內，終將因空氣耗盡而熄滅。2E is another conventional anti-surge (lightning strike) breaking method in which the surge absorber 101 is elastically tightened with the two elastic conductive contact pieces 104 by a resilient rubber ring 103, so that the main power source is thus in contact with the conduction. When the surge receiver 101 is heated to a high temperature section during a microsecond, the elastic rubber ring 103 will be "slowly" blown, and the two elastic contact pieces 104 are elastically separated from the main power source to form an open circuit. At this time, the elastic rubber ring 103 is burned by the surge absorber 101 at a high temperature, but is enclosed in a fireproof sealed space 100, and is eventually extinguished due to exhaustion of air.
圖2F係揭露一種防突波開關模組，應用於一電源系統，此開關模組包括一電源開關105、一絕緣件106、一突波吸收器107及一熱縮帶108。絕緣件106插設在電源開關105上；突波吸收器107與電源開關105相鄰；熱縮帶108與突波吸收器107及絕緣件106連接，熱縮帶108用以藉由突波吸收器107的溫度產生收縮作用；當絕緣件106於初始狀態時，不影響電源開關的切換，當熱縮帶108的收縮程度足以驅動絕緣件阻斷電源開關105的啟動時，電源開關105呈斷路狀態。此類型專利見諸TW I408717(即美國專利US Patent No.8,643,462)。2F discloses an anti-surge switch module applied to a power supply system. The switch module includes a power switch 105, an insulator 106, a surge absorber 107, and a heat shrink band 108. The insulating member 106 is inserted on the power switch 105; the surge absorber 107 is adjacent to the power switch 105; the heat shrink band 108 is connected to the surge absorber 107 and the insulating member 106, and the heat shrink band 108 is used for absorption by the surge. The temperature of the device 107 is contracted; when the insulating member 106 is in the initial state, it does not affect the switching of the power switch. When the shrinkage of the heat shrinkable tape 108 is sufficient to drive the insulating member to block the start of the power switch 105, the power switch 105 is open. status. This type of patent is found in TW I408717 (i.e., U.S. Patent No. 8,643,462).
惟查，以上防雷擊、防突波之結構除有品質難確保，高溫危險，反應緩慢外，皆有體積過大、構件太複雜之侷限性，因此需要更多空間及組立工序，故只能採外接獨立於開關外部之方式施作，無法內建在開關內，因此尚有改善空間。However, the above structures for lightning protection and anti-surge are not only difficult to ensure quality, high temperature danger, slow response, but also have limitations of excessive volume and complicated components. Therefore, more space and assembly processes are required. The external connection is applied independently of the switch and cannot be built into the switch, so there is room for improvement.
依據UL1449第三版(2009.10)即有新增TYPE 4 SPD-元件類的突波保護器之規範。同時新版並納入低電壓(1000V以下)避雷器(Low Voltage surge Arrestres)檢驗。名稱由(Transient Voltage Surge Suppressors)改為(Surge Protective Devices) 顯見元件一體化與具備防雷(surge Arrestres)快速斷電的必要性。According to UL1449 3rd Edition (2009.10), there is a specification for a new TYPE 4 SPD-component surge protector. At the same time, the new version is included in the Low Voltage surge arrester (Low Voltage surge Arrestres). The name changed from (Transient Voltage Surge Suppressors) to (Surge Protective Devices). It is obvious that component integration and the need for lightning protection (surge Arrestres).
是以，思考如何將一過電壓保護裝置內建結合在過電流保護開關10內，並且使熱不需經由溫度保險絲外殼間接傳導，而是直接傳熱至感溫體，並改進傳導面的傳導效率，確保作動皆能順利完成者，為本發明所欲解決之課題。Therefore, it is considered how to integrate an over-voltage protection device in the overcurrent protection switch 10, and the heat does not need to be indirectly transmitted through the temperature fuse casing, but directly transfers heat to the temperature sensing body, and improves the conduction of the conduction surface. Efficiency, ensuring that the actuation can be successfully completed, is the subject of the present invention.

一電壓過載感應元件70，其係由一壓敏電阻71及一感溫柱72所組成，本實施例中，該壓敏電阻71係成一圓形裸片狀(即表面沒有包覆絕緣物質)，但不限定於此，其具有突波吸收功能，俾於電壓異常時將所吸收之電壓轉換為熱溫，惟其原理及構成係屬先前技術，容不贅述。該壓敏電阻71其具備一第一表面711及一相反面之第二表面712，且壓敏電阻71以一導線713連接至該第二接線片50之延伸部50a，該感溫柱72係由到達預定溫度即瞬間熔解之熱敏物質所構成，其底面721貼合在該壓敏電阻71之第二表面712，並使該壓敏電阻71之第一表面711貼靠在該第三接線片60的接合面61，形成電性接觸，即其底面貼合在該壓敏電阻71之第二表面712，並利用黏合介質使其完整接合及助熔，再者，該感溫柱72之前端722係朝向該中段板52之第二側邊522，其目的在於使該感溫柱72直接或間接施予該中段板52一個向第二側邊522的頂制力，俾於常態時迫使該中段板52與延伸部50a保持電性接觸。A voltage overload sensing element 70 is composed of a varistor 71 and a temperature sensing column 72. In this embodiment, the varistor 71 is formed into a circular die shape (ie, the surface is not covered with an insulating material). However, the present invention is not limited thereto, and has a surge absorption function, and converts the absorbed voltage into a thermal temperature when the voltage is abnormal. However, the principle and the configuration are prior art and are not described herein. The varistor 71 has a first surface 711 and a second surface 712 opposite thereto, and the varistor 71 is connected to the extension 50a of the second tab 50 by a wire 713. It is composed of a heat-sensitive substance that reaches a predetermined temperature, that is, instantaneously melted, and its bottom surface 721 is attached to the second surface 712 of the varistor 71, and the first surface 711 of the varistor 71 is placed against the third wire. The bonding surface 61 of the sheet 60 is electrically contacted, that is, the bottom surface thereof is attached to the second surface 712 of the varistor 71, and is fully bonded and fluxed by the bonding medium. Further, the temperature sensing column 72 is The front end 722 is oriented toward the second side 522 of the middle plate 52. The purpose is to directly or indirectly apply the temperature sensing column 72 to the top side of the middle plate 52 to the second side 522. The midsection plate 52 is in electrical contact with the extension 50a.
本實施例中，該感溫柱72係可為非金屬之松香(Resin)類或洋菜(Agar)類熱敏物質所構成，或金屬之伍德易熔金(Wood's fusible metal)等快熔金屬化合物(例如:一般保險絲用之金屬化合物)所構成，但不限定於此。因此，只要在突波吸收器溫升達到所設定溫度時，且此類物質在溫度未升至高溫時卽熔化作動斷電的導電或非導電物質皆可。此化合物在於有固定的熔點，具有正負1度C快速斷鏈熔解特性。且一較佳實施例，係將該感溫柱72係設成底面721面積最大，並往前端722呈漸縮之錐狀體，且其底面721可利用相容材料作為助熔黏劑，將其黏合固定在該壓敏電阻71之第二表面712而結合為一體。據此，其結合為一體除了方便組裝在殼體31內，二者黏合穩固且接觸面積大，更有助於熱傳導效率，亦即該壓敏電阻71可以將熱溫迅速傳遞至該感溫柱72，使其瞬間熔解，如此才能達成本發明所要之目的。In this embodiment, the temperature sensing column 72 can be made of a non-metallic rosin (Resin) or agar (Agar) type heat sensitive material, or a metal fast-melting metal such as Wood's fusible metal. A compound (for example, a metal compound for a general fuse) is used, but is not limited thereto. Therefore, as long as the temperature rise of the surge absorber reaches the set temperature, and such a substance does not melt or illuminate the conductive or non-conductive substance when the temperature is not raised to a high temperature. This compound has a fixed melting point and a fast chain-breaking melting property of plus or minus 1 degree C. In a preferred embodiment, the temperature sensing column 72 is configured such that the bottom surface 721 has the largest area and is tapered toward the front end 722, and the bottom surface 721 can be made of a compatible material as a fluxing adhesive. It is bonded and fixed to the second surface 712 of the varistor 71 to be integrated. Accordingly, the combination of the two is not only convenient to be assembled in the casing 31, but also the bonding is stable and the contact area is large, which is more conducive to heat conduction efficiency, that is, the varistor 71 can quickly transfer the thermal temperature to the temperature sensing column. 72, so that it is melted instantaneously, in order to achieve the intended purpose of the present invention.
一彈簧80，其具備一第一端及81一相反之第二端82，且該第一端81係設在該中段板52的第二側邊522，而該第二端82係抵靠在殼體31內所設之止擋面34，使該彈簧80提供一彈性力朝向該感溫柱72。a spring 80 having a first end 81 and an opposite second end 82, and the first end 81 is disposed on the second side 522 of the mid-segment plate 52, and the second end 82 is abutted against A stop surface 34 is provided in the housing 31 such that the spring 80 provides an elastic force toward the temperature sensing column 72.
再者，由於該彈簧80係設在該中段板52的第二側邊522，使其提供一彈性力朝向該感溫柱72的方向頂制。而平時因該感溫柱72之前端722頂住該中段板52的第一側邊521之彈性片523，如圖4所示，因該感溫柱72熔解前係呈固體，所以彈簧80係呈現被壓縮狀態，俾能使該中段板52保持與該延伸部50a電性接觸。Moreover, since the spring 80 is disposed on the second side 522 of the mid-segment plate 52, it provides an elastic force to be pressed toward the temperature sensing column 72. The elastic piece 523 of the first side edge 521 of the middle plate 52 is normally held by the front end 722 of the temperature sensing column 72, as shown in FIG. 4, because the temperature sensing column 72 is solid before being melted, the spring 80 is Presenting the compressed state, the crucible enables the mid-segment plate 52 to remain in electrical contact with the extension 50a.
藉此，如圖5所示，當第一接點411與第二接點511接觸導通（ON），遇高電壓使壓敏電阻71溫度瞬間上升高於感溫柱72熔融值時，該感溫柱72熔化，使得該彈簧80對應側之頂制力消失，進而使得該作動部50b產生位移，強迫該第一接線片40係與該第二接線片50之輸出端形成斷路（OFF）。Therefore, as shown in FIG. 5, when the first contact 411 and the second contact 511 are in contact with each other (ON), when the high voltage causes the temperature of the varistor 71 to rise instantaneously higher than the melting value of the temperature sensing column 72, the feeling The temperature column 72 is melted, so that the top force of the corresponding side of the spring 80 disappears, and the actuation portion 50b is displaced, forcing the first terminal 40 to form an open circuit with the output end of the second terminal 50.
承上，在一可行實施例中，該作動部50b之中段板52的第一側邊521，設有一凸起且短距離之彈性片523與該感溫柱72接觸，且該彈性片523上相對於感溫柱72之前端722，設有一朝第二側邊522(即朝該彈簧80的方向)凹入之定位體524，供該感溫柱72之前端722嵌入定位。本實施例中，該彈性片523係可由中段板52表面直接衝壓成型，因其具有彈性可供該感溫柱72之前端722緊迫；藉此，該中段板52之第二側邊522即可與延伸部50a確保有效接觸；但不限定於此。亦即該中段板52表面不限定要衝壓成型該彈性片523，該彈性片523亦可由一彈簧(圖未示)所取代，或是直接將該中段板52改為一彈性板，亦可取代彈簧片523或一彈簧(圖未示) ，本實施例中，該彈性片523之目的在於提供一彈性空間，其一方面可使得該中段板52能有效接觸該該延伸部50a，另一方面則方便該感溫柱72的裝設，否則該彈性片523之長度必須計算準確，才能恰好嵌置在該壓敏電阻71與中段板52之間。此外，該彈性片523另一功能係可作為隔熱之用，以避免該第二接線片50伸出該殼體31外之延伸部50a需長時間銲接加工時雖有兩接觸點緩衝隔熱亦可能因長時間銲接使該感溫柱72尚未使用即發生熔融之可性，當然其一可行實施例包括可加一概呈錐形之絕緣隔熱帽73在該感溫柱72的前端，如此一來，該中段板52表面無論是使用衝壓成型之彈性片523，或彈簧或將該中段板52改為一彈性板，皆不會使該感溫柱72於加工過程中，導致溫度過熱熔融之虞。且該絕緣隔熱帽73亦可作為感溫柱72加強絕緣之用，例如: 感溫柱72係由伍德易熔金所構成時，再者，當該感溫柱72瞬間熔解時，該絕緣隔熱帽73可如圖5所示，將熔解之感溫柱72覆蓋住。是以，該絕緣隔熱帽73可於需要加強耐溫或絕緣時使用。In a possible embodiment, the first side 521 of the middle plate 52 of the actuating portion 50b is provided with a convex and short distance elastic piece 523 contacting the temperature sensing column 72, and the elastic piece 523 is placed thereon. With respect to the front end 722 of the temperature sensing column 72, a positioning body 524 recessed toward the second side 522 (ie, in the direction of the spring 80) is provided for the front end 722 of the temperature sensing column 72 to be embedded. In this embodiment, the elastic piece 523 can be directly press-formed from the surface of the middle plate 52, because it has elasticity to allow the front end 722 of the temperature sensing column 72 to be pressed; thereby, the second side 522 of the middle plate 52 can be The effective contact with the extension portion 50a is ensured; however, it is not limited thereto. That is, the surface of the middle plate 52 is not limited to be press-formed into the elastic piece 523. The elastic piece 523 can also be replaced by a spring (not shown), or the middle plate 52 can be directly changed into an elastic plate. The spring piece 523 or a spring (not shown), in the embodiment, the elastic piece 523 is intended to provide an elastic space, which on the one hand enables the middle plate 52 to effectively contact the extension 50a, and on the other hand The mounting of the temperature sensing column 72 is facilitated, otherwise the length of the elastic piece 523 must be calculated accurately so as to be exactly embedded between the varistor 71 and the middle plate 52. In addition, the other function of the elastic piece 523 can be used as a heat insulation to prevent the second lug 50 from extending beyond the extension portion 50a of the casing 31. It is also possible that the temperature sensing column 72 may be melted due to long-term soldering. Of course, a possible embodiment includes an insulating and insulating cap 73 which can be added with a tapered shape at the front end of the temperature sensing column 72. In addition, the surface of the middle plate 52, whether using the stamped elastic piece 523, or the spring or the middle plate 52 is changed to an elastic plate, does not cause the temperature sensing column 72 to undergo temperature overheating during processing. After that. The insulating and insulating cap 73 can also be used as the sensible temperature column 72 for reinforced insulation, for example: when the temperature sensing column 72 is composed of Wood Refractory Gold, and when the temperature sensing column 72 is melted instantaneously, the insulation The insulating cap 73 can be covered by the molten temperature sensing column 72 as shown in FIG. Therefore, the insulating and heat insulating cap 73 can be used when it is required to strengthen temperature resistance or insulation.
承上，本實施例中，該彈性片523之彈性位移的距離遠小於該彈簧80的彈性位移的距離，如此一來，當該感溫柱72發生熔解時，該彈簧80的彈性位移有較長的距離，可順利推開中段板52，瞬間使中段板52脫離該延伸部50a形成斷路(OFF) ，確保用電安全。In this embodiment, the elastic displacement of the elastic piece 523 is far less than the elastic displacement of the spring 80. Thus, when the temperature sensing column 72 is melted, the elastic displacement of the spring 80 is relatively high. With a long distance, the middle plate 52 can be smoothly pushed open, and the middle plate 52 is momentarily separated from the extending portion 50a to form an open circuit (OFF), thereby ensuring safe use of electricity.
如圖5所示，當第一接點411與第二接點511接觸導通（ON），且遇過電壓而壓敏電阻71(突波吸收器)溫度瞬間升高至預設值時，該感溫柱72即瞬間熔解，使得該彈簧80對應側之頂制力消失，本實施例中，該作動部50b整體係呈剛性結構，當該感溫柱72產生熔解，該彈簧80推頂該中段板52時，迫使設於上段部51之第二接點511脫離該第一接點411，形成斷路狀態（OFF）。亦即在本實施例中，該具有剛性之作動部50b係可設呈L型或彎曲型，並與該延伸部50a呈各自成型之獨立元件，且其接觸位置，可分別相向設有一第三接點53及一第四接點54，此時不只該第一接點411與該第二接點511分離，且該第三接點53與第四接點54亦同步分離，但不限定於此。例如: 可將該中段板52係設成撓性，而上段部51仍維持剛性，於是當該感溫柱72產生熔解，該彈簧80推頂該中段板52時，設於上段部51之第二接點511不會動，該第一接點411與該第二接點511不分離，僅該第三接點53與第四接點54分離，形成斷路狀態（OFF），如此亦可實施。As shown in FIG. 5, when the first contact 411 is in contact with the second contact 511, and the voltage is applied and the temperature of the varistor 71 (surge absorber) is instantaneously increased to a preset value, the temperature is raised to a preset value. The temperature sensing column 72 is instantaneously melted, so that the top force of the corresponding side of the spring 80 disappears. In this embodiment, the actuating portion 50b has a rigid structure as a whole. When the temperature sensing column 72 is melted, the spring 80 pushes the top. In the middle plate 52, the second contact 511 provided in the upper portion 51 is forced out of the first contact 411 to form an open state (OFF). That is, in the embodiment, the rigid actuating portion 50b can be provided in an L-shaped or curved shape, and is formed as a separate component with the extending portion 50a, and the contact position thereof can be respectively disposed opposite to each other. The contact point 53 and the fourth contact point 54 are not only separated from the second contact point 511, but the third contact point 53 and the fourth contact point 54 are also separated, but are not limited to this. For example, the middle plate 52 can be made flexible, and the upper portion 51 is still rigid, so that when the temperature sensing column 72 is melted, the spring 80 is pushed to the middle plate 52, and is disposed in the upper portion 51. The second contact 511 does not move, the first contact 411 and the second contact 511 are not separated, and only the third contact 53 and the fourth contact 54 are separated to form an open state (OFF), which can also be implemented. .
本實施例中，該第二接線片50之延伸部50a係設在殼體31之底部，但不限定於此；例如該第二接線片50之延伸部50a亦可設殼體31側邊或其中任一方向(圖未示) ，亦不影響本發明上述特徵之實施。In this embodiment, the extension portion 50a of the second lug 50 is disposed at the bottom of the casing 31, but is not limited thereto; for example, the extension portion 50a of the second lug 50 may be provided with the side of the casing 31 or Any of the directions (not shown) does not affect the implementation of the above features of the present invention.
圖6所示係本發明之主要元件分解立體圖，本發明上述結構能夠遇過電壓而壓敏電阻71溫度瞬間升高至預設值時，該感溫柱72即瞬間熔解，其有一重要特徵，即感溫柱72係設計成與壓敏電阻71有較大的接觸面積，並利用黏合介質使其完整接合。由於該壓敏電阻（Metal Oxide Varistor 或 Voltage Dependent Resistor，VDR），又稱變阻器，是一種具有顯著非歐姆導體性質的電子元件，電阻值會隨外部電壓而改變，因此它的電流-電壓特性曲線具有顯著的非線性，廣泛的被應用在電子線路中，來防護因為電力供應系統的暫態電壓突波所可能對電路的傷害。本發明運用壓敏電阻71當高壓來到時，其表面溫度迅速升高，且感溫柱72係設計成與壓敏電阻71有較大的接觸面積，於是壓敏電阻71溫度瞬間升高至預設值時，該感溫柱72即可迅速反應而瞬間熔解，使得該彈簧80對應側之頂制力消失，進而使得該作動部50b產生位移，強迫該第一接線片40係與該第二接線片50之輸出端形成斷路（OFF）。FIG. 6 is an exploded perspective view of the main components of the present invention. When the above structure is capable of overvoltage and the temperature of the varistor 71 is instantaneously increased to a preset value, the temperature sensing column 72 is instantaneously melted, and has an important feature. That is, the temperature sensing column 72 is designed to have a large contact area with the varistor 71, and is fully joined by the bonding medium. Since the varistor (Metal Oxide Varistor or Voltage Dependent Resistor, VDR), also known as varistor, is an electronic component with significant non-ohmic conductor properties, the resistance value changes with the external voltage, so its current-voltage characteristic curve It has significant nonlinearity and is widely used in electronic circuits to protect against circuit damage due to transient voltage surges in power supply systems. When the high voltage comes, the surface temperature of the varistor 71 is rapidly increased, and the temperature sensing column 72 is designed to have a large contact area with the varistor 71, so that the temperature of the varistor 71 is instantaneously increased to When the preset value is reached, the temperature sensing column 72 can react quickly and melt instantaneously, so that the topping force of the corresponding side of the spring 80 disappears, thereby causing displacement of the actuating portion 50b, forcing the first lug 40 to be coupled with the first The output of the two lugs 50 forms an open circuit (OFF).
藉助上揭技術特徵，本發明解決了習用電流過載保護開關須外接溫度保險絲及突波吸收器的缺失，在一般電流過載保護開關的內部空間，巧妙內建一電壓過載保護裝置，遇高電壓時，作為電流輸出之第二接線片50，其作動部50b會迅速產生位移，使輸出端形成斷路之結構，且利用發熱之壓敏電阻71與可熔解體之感溫柱72，採直接且大面積接觸而能達到更快速與密合之熱傳導效果，可確保每次皆能作動成功且未達高溫即可迅速斷電，是以，本發明除了具備電流過載保護功能外，進一步在同一個開關內同時兼具過電壓保護設計，具有用電安全且在配設使用方便之功效增進。By means of the above-mentioned technical features, the invention solves the problem that the conventional current overload protection switch needs an external temperature fuse and a surge absorber. In the internal space of the general current overload protection switch, a voltage overload protection device is ingeniously built, and when a high voltage is encountered As the second lug 50 of the current output, the actuating portion 50b is rapidly displaced, so that the output end forms an open circuit structure, and the heat-sensitive varistor 71 and the resolvable body temperature sensing column 72 are directly and largely The area contact can achieve a faster and tighter heat conduction effect, ensuring that the operation can be performed successfully every time and the high temperature can be quickly turned off. Therefore, in addition to the current overload protection function, the present invention is further in the same switch. It also has an overvoltage protection design, which is safe to use and safe to use.
