Abstract
Description
本發明關於表面貼著保險絲及具有表面貼著保險絲的結構,且特別有關於高耐用度之保險絲,這是因為使用具有高機械強度由陶瓷材料構成的非導電性元件以及陶瓷管,陶瓷管藉由銲接環與密封電極接合,且透過改善時間延遲特性和生產方法,陶瓷管可以在高電壓穩定地使用。 The present invention relates to a surface-attached fuse and a structure having a surface-attached fuse, and particularly relates to a fuse of high durability, because a non-conductive member composed of a ceramic material having high mechanical strength and a ceramic tube are used, and the ceramic tube is used. The ceramic tube can be stably used at a high voltage by bonding the welding ring to the sealing electrode and improving the time delay characteristics and the production method.
保險絲通常設置於電子裝置之中,例如電視機、電腦、卡式收音機、小型電子裝置與類似電子裝置。當過電壓施加其中時,保險絲會熔化阻斷功率傳遞,避免電路及電子元件被過電壓傷害。 Fuses are typically placed in electronic devices such as televisions, computers, card radios, small electronic devices, and similar electronic devices. When an overvoltage is applied to it, the fuse will melt and block the power transfer, preventing the circuit and electronic components from being damaged by overvoltage.
在正常情況下,即使最大額定電壓施加在保險絲上,保險絲不允許產生大量的熱,也不應該被燒斷(斷開)(blown out)。保險絲僅在異常情況下會被燒斷。保險絲需有極佳的時間延遲特性,當例為突波電壓之短暫高電壓通過其上時,保護其不被燒斷。 Under normal conditions, even if the maximum rated voltage is applied to the fuse, the fuse is not allowed to generate a large amount of heat and should not be blown out. The fuse will only be blown out under abnormal conditions. The fuse needs to have excellent time delay characteristics. When the transient high voltage of the surge voltage passes through it, it is protected from being blown.
第10圖是習知保險絲的側視圖。參考第10圖,韓國專利申請公告號為1992-0007019(公布於1992年4月28 日)之專利揭露一種保險絲,其製造方法係插入一端具有彎曲部7之臨時套管6,並使用內部中央有燈絲2之玻璃管1在一端與矽上螺旋器(silicon creeper)8互鎖;退回臨時套管6,將玻璃管1中的燈絲2對準,並且移動玻璃管1中的燈絲2’,暫時對齊玻璃管1中的燈絲2,形成對角線;將具有內引線4的金屬帽3設置於玻璃管1兩端,在玻璃管1使用銲鐵9將金屬帽3焊接在暫時對齊的燈絲2兩端,形成對角線。 Figure 10 is a side view of a conventional fuse.

Fig. 3 is an exploded side view showing the surface-attached fuse of the first embodiment of the present invention.
如第1A圖至第3圖所示,本發明揭露之表面貼著保險絲100通常包括陶瓷管120、密封電極130、保險絲單元110與銲接環150。 As shown in FIGS. 1A through 3, the surface-attachment fuse 100 disclosed herein generally includes a ceramic tube 120, a sealing electrode 130, a fuse unit 110, and a solder ring 150.
舉例來說,本發明之表面貼著保險絲100包括其內充有惰性氣體的陶瓷管120;一對密封電極130,密封電極130設置於陶瓷管120兩端;保險絲單元110,保險絲單元110設置於陶瓷管120之中且與密封電極130電性連接,且包括可熔元件115;以及銲接環150,銲接環150密封於陶瓷管120和每一個密封電極130之間。 For example, the surface-attached fuse 100 of the present invention includes a ceramic tube 120 filled with an inert gas; a pair of sealing electrodes 130, the sealing electrode 130 is disposed at both ends of the ceramic tube 120; and the fuse unit 110, the fuse unit 110 is disposed at The ceramic tube 120 is electrically connected to the sealing electrode 130 and includes a fusible element 115; and a welding ring 150 sealed between the ceramic tube 120 and each of the sealing electrodes 130.
參考第1A圖,本發明揭露之保險絲單元110包括非導電性元件111;端電極117,端電極117設置於非導電性元件111兩端;以及可熔元件115,可熔元件115與端電極117電性連接。 Referring to FIG. 1A, the fuse unit 110 of the present invention includes a non-conductive element 111; a terminal electrode 117, the terminal electrode 117 is disposed at both ends of the non-conductive element 111; and a fusible element 115, a fusible element 115 and a terminal electrode 117 Electrical connection.
非導電性元件111可為圓柱形,且可由例為鋁之陶瓷材料構成。此外,可熔元件115設置於非導電性元件111之外表面。 The non-conductive element 111 may be cylindrical and may be constructed of a ceramic material such as aluminum. Further, the fusible element 115 is disposed on the outer surface of the non-conductive element 111.
端電極117可由銅合金構成且設置於非導電性元件111兩端以電性連接密封電極130與保險絲單元110。 The terminal electrode 117 may be made of a copper alloy and disposed at both ends of the non-conductive element 111 to electrically connect the sealing electrode 130 and the fuse unit 110.
可熔元件115螺旋纏繞於非導電性元件111之外表面。因為可熔元件115的長度比第1B圖和第1C圖的可熔元件115a和115b的長度還長,所以保護表面貼著保險絲100不被突波電壓燒斷的時間延遲特性得以改善。因此,表面貼著保險絲100可穩定操作於例為250伏特(或更高)之高電壓。 The fusible element 115 is spirally wound around the outer surface of the non-conductive element 111. Since the length of the fusible element 115 is longer than the lengths of the fusible elements 115a and 115b of FIGS. 1B and 1C, the time delay characteristic of the protective surface against the fuse 100 being not blown by the surge voltage is improved. Therefore, the surface of the fuse 100 can be stably operated at a high voltage of, for example, 250 volts (or higher).
當過電流施加於可熔元件115時,可熔元件115被熔斷(斷開)。此外,舉例而言,可熔元件115可由銅(Cu)、銀(Ag)、銅銀合金、鎳銅合金、鎳鐵合金、銅表面鍍銀、鐵、鉻(Cr),以及主成分為鎳之鐵合金。 When an overcurrent is applied to the fusible element 115, the fusible element 115 is blown (opened). In addition, for example, the fusible element 115 may be made of copper (Cu), silver (Ag), copper-silver alloy, nickel-copper alloy, nickel-iron alloy, copper surface silver plating, iron, chromium (Cr), and the main component is nickel. iron alloy.
此外,參考第1B圖,本發明之保險絲單元110a包括中空圓筒狀之非導電性元件111;端電極117,端電極117設置於非導電性元件111兩端;以及可熔元件115a,可熔元件115a電性連接至端電極117且穿過非導電性元件111。 Further, referring to FIG. 1B, the fuse unit 110a of the present invention includes a hollow cylindrical non-conductive element 111; a terminal electrode 117 having end electrodes 117 disposed at both ends of the non-conductive element 111; and a fusible element 115a, fusible The element 115a is electrically connected to the terminal electrode 117 and passes through the non-conductive element 111.
此外,參考第1C圖,本發明之保險絲單元110b包括非導電性元件111;端電極117,端電極117設置於非導電性元件111兩端;以及可熔元件115b,可熔元件115b沿著長度方向設置於非導電性元件111外表面,以電性連接於端電極117。 Further, referring to FIG. 1C, the fuse unit 110b of the present invention includes a non-conductive element 111; a terminal electrode 117 having a terminal electrode 117 disposed at both ends of the non-conductive element 111; and a fusible element 115b having a length along the length of the fusible element 115b The direction is disposed on the outer surface of the non-conductive element 111 to be electrically connected to the terminal electrode 117.
因此,本發明揭露之保險絲單元110、110a及110b 能以多種形狀來形成,需視產品的用途和特定而定。 Therefore, the fuse unit 110, 110a and 110b disclosed in the present invention It can be formed in a variety of shapes depending on the purpose and specificity of the product.
本發明揭露之陶瓷管120具有圓柱狀外型且由陶瓷材料構成。圓柱狀的陶瓷管120兩端具有密封電極130並以密封電極130加以密封。此外,陶瓷管120的兩端透過銲接接面和密封電極130組裝在一起。 The ceramic tube 120 disclosed in the present invention has a cylindrical outer shape and is composed of a ceramic material. The cylindrical ceramic tube 120 has a sealing electrode 130 at both ends and is sealed by a sealing electrode 130. Further, both ends of the ceramic tube 120 are assembled through the solder joint and the sealing electrode 130.
如上述,密封電極130設置於陶瓷管120兩端。 As described above, the sealing electrode 130 is disposed at both ends of the ceramic tube 120.
此外,舉例來說,密封電極130可由銅合金構成。 Further, for example, the sealing electrode 130 may be composed of a copper alloy.
舉例來說,每一個密封電極130可包括接觸部133,接觸部133朝陶瓷管120內部凸起並插入陶瓷管120且與保險絲單元110和接合於銲接環150之接面部131接觸。 For example, each of the sealing electrodes 130 may include a contact portion 133 that protrudes toward the inside of the ceramic tube 120 and is inserted into the ceramic tube 120 and is in contact with the fuse unit 110 and the joint portion 131 joined to the welding ring 150.
因為密封電極130之接觸部133朝內突起,所以密封電極130可有效地組裝於銲接環150或陶瓷管120。因為陶瓷管120內之保險絲單元110在銲接過程中會被擠壓,密封電極130和接觸部133之間的電性連接會被改善。 Since the contact portion 133 of the sealing electrode 130 protrudes inward, the sealing electrode 130 can be efficiently assembled to the welding ring 150 or the ceramic tube 120. Since the fuse unit 110 in the ceramic tube 120 is pressed during the soldering process, the electrical connection between the sealing electrode 130 and the contact portion 133 is improved.
本發明之銲接環150會在陶瓷管120和每一個密封電極130之間熔化,作為熔填金屬,密封電極130在銲接時作為連接陶瓷管120和密封電極130之本體金屬。 The welding ring 150 of the present invention melts between the ceramic tube 120 and each of the sealing electrodes 130 as a filler metal, and the sealing electrode 130 serves as a body metal connecting the ceramic tube 120 and the sealing electrode 130 during soldering.
舉例來說,銲接環150可由包括銅(Cu)、銀(Ag)與鋅(Zn)之合金構成。 For example, the weld ring 150 may be composed of an alloy including copper (Cu), silver (Ag), and zinc (Zn).
此外,銲接製程是以比銲接環150之熔點更高的溫度進行,作為熔填金屬,且比陶瓷管120和密封電極130的熔點更低的溫度進行,作為本體金屬。 Further, the soldering process is performed at a temperature higher than the melting point of the solder ring 150, as a filler metal, and is performed at a temperature lower than the melting point of the ceramic tube 120 and the sealing electrode 130 as a bulk metal.
用來表示熔填金屬和本體金屬之間親和度的濕潤特性是影響銲接接面的重要因素。換言之,當陶瓷管120和密 封電極130之間的銲接環其濕潤特性不佳時,便無法形成其間的接面。因此,本發明使用具有極佳濕潤特性之陶瓷材料和熔填金屬來形成容納保險絲單元110的陶瓷管120,而非使用濕潤特性不佳的玻璃材料和熔填金屬來形成陶瓷管。 The wetting characteristics used to indicate the affinity between the filler metal and the bulk metal are important factors influencing the solder joint. In other words, when the ceramic tube 120 and dense When the welded ring between the sealing electrodes 130 has poor wettability, the joint between them cannot be formed. Therefore, the present invention uses a ceramic material having excellent wetting characteristics and a filler metal to form the ceramic tube 120 accommodating the fuse unit 110, instead of using a glass material and a filler metal having poor wettability to form a ceramic tube.
此外,因為銲接環150在陶瓷管120和密封電極130的表面上熔化時會發生毛細作用,所以使用銲接環150的銲接接面具有較佳之結合強度且具有極佳抗震特性(如震動或其他物理現象)。 In addition, since the welding ring 150 is wicked when it is melted on the surfaces of the ceramic tube 120 and the sealing electrode 130, the welded joint using the welding ring 150 has a good bonding strength and excellent shock resistance characteristics (such as vibration or other physics). phenomenon).
同時,銲接環150的外表面151設置於與陶瓷管120之外表面等高之處,且銲接環150的內表面152設置於朝陶瓷管120內部延伸至比陶瓷管120內緣更內部之處。 At the same time, the outer surface 151 of the weld ring 150 is disposed at the same height as the outer surface of the ceramic tube 120, and the inner surface 152 of the weld ring 150 is disposed to extend inside the ceramic tube 120 to a position more inside than the inner edge of the ceramic tube 120. .
如上所述,因為陶瓷管120是以較佳機械強度之陶瓷材料構成,且使用銲接環150來接合陶瓷管120和每一個密封電極130,所以本發明揭露之表面貼著保險絲100耐用度較佳,表面貼著保險絲100可穩定操作於高電壓。 As described above, since the ceramic tube 120 is made of a ceramic material of a preferable mechanical strength, and the soldering ring 150 is used to join the ceramic tube 120 and each of the sealing electrodes 130, the surface of the present invention is preferably attached to the fuse 100 with better durability. The surface of the fuse 100 can be stably operated at a high voltage.
第4圖是本發明第二實施例之表面貼著保險絲100a的側視圖。 Fig. 4 is a side view showing the surface-attached fuse 100a of the second embodiment of the present invention.
參考第4圖,本發明之表面貼著保險絲100a更包括銲接元件160,銲接元件160將每一個接觸部133與每一個端電極117連接起來。 Referring to Fig. 4, the surface-attachment fuse 100a of the present invention further includes a soldering member 160 which connects each of the contact portions 133 with each of the terminal electrodes 117.
舉例而言,銲接元件160可為板形且可由包括銅(Cu)、銀(Ag)和鋅(Zn)之合金構成。 For example, the soldering element 160 can be plate shaped and can be composed of an alloy including copper (Cu), silver (Ag), and zinc (Zn).
如同銲接環150,銲接元件160會在接觸部133和端電極117之間熔化,並將接觸部133和端電極117接合在一 起。 Like the weld ring 150, the welding element 160 melts between the contact portion 133 and the terminal electrode 117, and joins the contact portion 133 and the terminal electrode 117 to one Start.
因此,藉由銲接元件160,保險絲單元110可與密封電極130更牢靠地接合,藉此改善表面貼著保險絲100a的耐用度。 Therefore, by the soldering member 160, the fuse unit 110 can be more firmly engaged with the sealing electrode 130, thereby improving the durability of the surface against the fuse 100a.
第5圖是本發明第三實施例之表面貼著保險絲100b的側視圖。 Fig. 5 is a side view of the surface-attached fuse 100b according to the third embodiment of the present invention.
參考第5圖,本發明揭露之表面貼著保險絲100b的銲接環150a與陶瓷管120和保險絲單元110均接合。 Referring to Fig. 5, the welding ring 150a of the present invention, which is attached to the fuse 100b, is joined to both the ceramic tube 120 and the fuse unit 110.
換言之,銲接環150a包括與陶瓷管120一端接合之外部153;以及與保險絲單元110一端接合(例如端電極117)之內部154。 In other words, the weld ring 150a includes an outer portion 153 that engages one end of the ceramic tube 120; and an inner portion 154 that engages one end of the fuse unit 110 (eg, the terminal electrode 117).
因此,銲接環150a的厚度可大於或等於接觸部133a的厚度。這是因為當銲接環150a的厚度大於接觸部133a的厚度時,銲接環150a會在熔化後與陶瓷管120和端電極117接合。 Therefore, the thickness of the weld ring 150a may be greater than or equal to the thickness of the contact portion 133a. This is because when the thickness of the weld ring 150a is larger than the thickness of the contact portion 133a, the weld ring 150a is joined to the ceramic tube 120 and the terminal electrode 117 after melting.
此外,相較於第2圖之銲接環150,銲接環150a的內部154朝更內部之處延伸,且相較於第2圖的接觸部133,接觸部133a的寬度更窄。 Further, compared with the weld ring 150 of Fig. 2, the inner portion 154 of the weld ring 150a extends toward the inner portion, and the width of the contact portion 133a is narrower than that of the contact portion 133 of Fig. 2.
第6圖是本發明第四實施例之表面貼著保險絲100c的側視圖。 Fig. 6 is a side view showing the surface-attached fuse 100c of the fourth embodiment of the present invention.
參考第6圖,本發明揭露之表面貼著保險絲100c更包括電鍍層180,以改善銲接環150或銲接元件160與本體金屬之間的濕潤特性。 Referring to Figure 6, the surface-attached fuse 100c of the present invention further includes a plating layer 180 to improve the wetting characteristics between the solder ring 150 or the soldering member 160 and the body metal.
舉例來說,電鍍層180(181、183和185)形成於接 觸部133、接面部131與端電極117之至少一者之上,以改善銲接環150或銲接元件160之接合強度,藉由熔化過程。 For example, plating layers 180 (181, 183, and 185) are formed The contact portion 133, the contact portion 131 and the terminal electrode 117 are overlaid to improve the bonding strength of the solder ring 150 or the soldering member 160 by the melting process.
此外,電鍍層180可包括鎳(Ni)或鈦(Ti),且可由例為Ni3P之化合所組成。 Further, the plating layer 180 may include nickel (Ni) or titanium (Ti), and may be composed of a compound such as Ni3P.
第7A圖和第7B圖是本發明第五實施例之表面貼著保險絲100d的側視圖。 7A and 7B are side views of the surface-attached fuse 100d of the fifth embodiment of the present invention.
參考第7A圖和第7B圖,本發明每一個密封電極130b具有平板外形,而無突出的接觸部,這個特徵與第1圖至第6圖所示之密封電極不同。 Referring to Figs. 7A and 7B, each of the sealing electrodes 130b of the present invention has a flat plate shape without protruding contact portions, and this feature is different from the sealing electrodes shown in Figs. 1 to 6 .
此外,銲接環150b具有平板外形,使其能同時與陶瓷管120一端和端電極117接合(第7A圖)。 Further, the welding ring 150b has a flat plate shape so that it can be simultaneously joined to one end of the ceramic tube 120 and the terminal electrode 117 (Fig. 7A).
此外,銲接環150c具有空心環外形,使得密封電極130b直接與端電極117接觸(第7B圖)。 Further, the welding ring 150c has a hollow ring shape such that the sealing electrode 130b is in direct contact with the terminal electrode 117 (Fig. 7B).
本發明揭露之一種表面貼著保險絲的製造方法將作詳細說明如下。 A method of manufacturing a surface-attached fuse disclosed in the present invention will be described in detail below.
第8A圖至第8F圖為本發明之一實施例之側視圖,其說明表面貼著保險絲100的製造方法。 8A to 8F are side views showing an embodiment of the present invention, which illustrates a method of manufacturing the surface-attached fuse 100.
如上所述,本發明所揭露之製造方法所形成的表面貼著保險絲100包括陶瓷管120,保險絲單元110設置其中,第一密封電極130和第二密封電極135分別插入陶瓷管120的兩端並和保險絲單元110連接,且第一銲接環150和第二銲接環155分別連接陶瓷管120和第一密封電極130和第二密封電極135。 As described above, the surface-attachment fuse 100 formed by the manufacturing method of the present invention includes a ceramic tube 120 in which the fuse unit 110 is disposed, and the first sealing electrode 130 and the second sealing electrode 135 are respectively inserted into both ends of the ceramic tube 120. The fuse unit 110 is connected, and the first solder ring 150 and the second solder ring 155 are connected to the ceramic tube 120 and the first and second sealing electrodes 130 and 135, respectively.
首先,參考第8A圖,在步驟S1,形成第一密封 電極130。第一密封電極130包括接觸部133,接觸部133朝陶瓷管120內部突起並被插入陶瓷管120且和保險絲單元110接合;以及接面部131,接面部131與銲接環150接合。 First, referring to FIG. 8A, in step S1, a first seal is formed. Electrode 130. The first sealing electrode 130 includes a contact portion 133 that protrudes toward the inside of the ceramic tube 120 and is inserted into the ceramic tube 120 and engaged with the fuse unit 110; and the surface portion 131 that is joined to the welding ring 150.
因此,參考第8B圖,在步驟S2,第一銲接環150和陶瓷管120依序堆疊在第一密封電極130之上。 Therefore, referring to FIG. 8B, in step S2, the first solder ring 150 and the ceramic tube 120 are sequentially stacked over the first sealing electrode 130.
第一銲接環150設置於第一密封電極130之接面部131之上,且陶瓷管120設置在第一銲接環150之上。 The first solder ring 150 is disposed on the joint surface 131 of the first sealing electrode 130, and the ceramic tube 120 is disposed on the first solder ring 150.
因此,參考第8C圖,在步驟S3,保險絲單元110被插入陶瓷管120之中。 Therefore, referring to FIG. 8C, in step S3, the fuse unit 110 is inserted into the ceramic tube 120.
保險絲單元110包括非導電性元件111;第一端電極117和第二端電極117a,第一端電極117和第二端電極117a設置於非導電性元件111兩端;以及可熔元件115,可熔元件115電性連接於第一端電極117和第二端電極117a。 The fuse unit 110 includes a non-conductive element 111; a first end electrode 117 and a second end electrode 117a, the first end electrode 117 and the second end electrode 117a are disposed at both ends of the non-conductive element 111; and the fusible element 115 The fuse element 115 is electrically connected to the first terminal electrode 117 and the second terminal electrode 117a.
插入後的保險絲單元110,其第一端電極117設置於第一密封電極130之接觸部133之上。在第一端電極117的內表面和非導電性元件111之間形成間隙G或空間。當第二密封電極135接合時(如後述),並且透過步驟S5所述之銲接製程,施加於其上的壓力會讓間隙G或空間消失。間隙G或空間可在保險絲單元110的組裝過程中自然地或人為地形成。 The inserted fuse unit 110 has its first terminal electrode 117 disposed above the contact portion 133 of the first sealing electrode 130. A gap G or a space is formed between the inner surface of the first terminal electrode 117 and the non-conductive element 111. When the second sealing electrode 135 is joined (as will be described later), and through the welding process described in step S5, the pressure applied thereto causes the gap G or the space to disappear. The gap G or space may be naturally or artificially formed during the assembly of the fuse unit 110.
然後,參考第8D圖,在步驟S4,第二銲接環155和第二密封電極135依序堆疊於陶瓷管120之上。 Then, referring to FIG. 8D, in step S4, the second solder ring 155 and the second sealing electrode 135 are sequentially stacked on the ceramic tube 120.
在銲接接面之前,透過步驟S1至步驟S4,組裝表面貼著保險絲100。 Before the solder joint is welded, the assembly surface is attached to the fuse 100 through steps S1 to S4.
然後,將經歷步驟S1至步驟S4之表面貼著保險 絲100設置在腔室C之中,並且在步驟S5,透過熔化第一銲接環150和第二銲接環155,將陶瓷管120和第一密封電極130和第二密封電極135密封。 Then, the surface that goes through steps S1 to S4 is covered with insurance. The wire 100 is disposed in the chamber C, and at step S5, the ceramic tube 120 and the first sealing electrode 130 and the second sealing electrode 135 are sealed by melting the first welding ring 150 and the second welding ring 155.
步驟S5可在其內充有惰性氣體之腔室C內進行,且密封後之陶瓷管120內部充有惰性氣體。此外,惰性氣體避免保險絲單元110氧化並改善耐用度。 The step S5 can be carried out in the chamber C in which the inert gas is filled, and the sealed ceramic tube 120 is filled with an inert gas. In addition, the inert gas prevents oxidation of the fuse unit 110 and improves durability.
表面貼著保險絲100被垂直置入縱向站立的腔室C(第8E圖)。加熱腔室C以熔化第一銲接環150和第二銲接環155,藉此完成接面(第8F圖)。 The surface is placed with the fuse 100 vertically placed into the chamber C standing longitudinally (Fig. 8E). The chamber C is heated to melt the first weld ring 150 and the second weld ring 155, thereby completing the joint (Fig. 8F).
將腔室C加熱至比第一密封電極130、第二密封電極135(第一和第二密封電極作為本體金屬)與陶瓷管120之熔點還低的溫度,以避免本體金屬解離。加熱的溫度可視第一銲接環150和第二銲接環155的材料在500℃至850℃的範圍內調整。舉例來說,當第一銲接環150和第二銲接環155的成分為包含銅和銀之合金(例如Ag25Cu)時,腔室C被加熱至800℃至850℃。可熔元件115可以銲接後不會燒斷的材料構成,舉例來說,鎳銅合金或鎳鐵合金。 The chamber C is heated to a temperature lower than the melting point of the first sealing electrode 130, the second sealing electrode 135 (the first and second sealing electrodes as the bulk metal) and the ceramic tube 120 to avoid dissociation of the bulk metal. The temperature of the heating can be adjusted in the range of 500 ° C to 850 ° C depending on the material of the first weld ring 150 and the second weld ring 155 . For example, when the composition of the first weld ring 150 and the second weld ring 155 is an alloy containing copper and silver (for example, Ag25Cu), the chamber C is heated to 800 ° C to 850 ° C. The fusible element 115 can be constructed of a material that does not blow after soldering, for example, a nickel-copper alloy or a nickel-iron alloy.
此外,當第一銲接環150和第二銲接環155由含銀、銅、鋅和錫之合金構成時,例如Ag56CuZnSn,銲接的溫度介於600℃至650℃。因此,除了鎳銅合金或鎳鐵合金之外,可熔元件115亦可由在800℃至850℃燒斷之銅、銀與銅銀合金構成。 Further, when the first weld ring 150 and the second weld ring 155 are composed of an alloy containing silver, copper, zinc and tin, such as Ag 56 CuZnSn, the soldering temperature is between 600 ° C and 650 ° C. Therefore, in addition to the nickel-copper alloy or the nickel-iron alloy, the fusible element 115 may be composed of copper, silver and a copper-silver alloy which are blown at 800 ° C to 850 ° C.
換言之,藉著將第一銲接環150和第二銲接環155的銲接溫度由800℃至850℃的範圍降低至600℃至650℃的範 圍,習知可熔元件之主要元素亦可使用,例如銅、銀、銅銀合金與類似合金。因此,保險絲的構成元素有很多選擇。此外,在800℃(或更高)時,可熔元件115即使沒有被燒斷,其亦會被熱所劣化。然而,當銲接過程在600℃至650℃的相對低溫進行時,因熱所導致之效能和品質劣化將會降低。 In other words, by reducing the soldering temperature of the first solder ring 150 and the second solder ring 155 from 800 ° C to 850 ° C to 600 ° C to 650 ° C The main elements of conventional fusible elements can also be used, such as copper, silver, copper-silver alloys and similar alloys. Therefore, there are many options for the constituent elements of the fuse. Further, at 800 ° C (or higher), the fusible element 115 is deteriorated by heat even if it is not blown. However, when the soldering process is carried out at a relatively low temperature of 600 ° C to 650 ° C, the efficiency and quality deterioration due to heat will be lowered.
接著,加熱後的第一銲接環150和第二銲接環155熔化以在密封狀態下透過毛細作用接合本體金屬的表面,從而減少厚度。 Next, the heated first weld ring 150 and the second weld ring 155 are melted to join the surface of the body metal by capillary action in a sealed state, thereby reducing the thickness.
第9圖是本發明之表面貼著保險絲100設置在基板表面的側視圖。 Fig. 9 is a side view showing the surface of the present invention in which the fuse 100 is placed on the surface of the substrate.
參考第9圖,引線並未圖示,且本發明表面貼著保險絲100之密封電極130與銲接球接合。因此,保險絲100可為表面接著裝置(SMD)。 Referring to Fig. 9, the lead wires are not shown, and the sealing electrode 130 of the surface of the present invention is bonded to the solder ball by the sealing electrode 130 of the fuse 100. Thus, the fuse 100 can be a surface mount device (SMD).
如上所述,本發明揭露一種表面貼著保險絲的製造方法,使用較佳機械強度的陶瓷材料作為陶瓷管,且使用銲接環連接陶瓷管和密封電極,因此表面貼著保險絲的接合強度和耐用度得以改善。 As described above, the present invention discloses a method of manufacturing a surface-attached fuse, using a ceramic material having a better mechanical strength as a ceramic tube, and using a soldering ring to connect the ceramic tube and the sealing electrode, so that the bonding strength and durability of the surface against the fuse are as follows. Improved.
此外,藉著將可熔元件纏繞於非導電性元件的外表面,時間延遲特性可以被改善,所以表面貼著保險絲可以穩定地操作於高電壓。 Further, by winding the fusible element around the outer surface of the non-conductive element, the time delay characteristic can be improved, so that the surface can be stably operated at a high voltage with the fuse attached thereto.
此外,藉著將銲接製程的溫度降低至600℃至650℃的範圍,即使在上述溫度範圍使用習知材料,可熔元件也不會燒斷。 Further, by lowering the temperature of the soldering process to a range of 600 ° C to 650 ° C, the fusible element is not blown even if a conventional material is used in the above temperature range.
如上所述,根據本發明揭露之表面貼著保險絲的 製造方法,其透過銲接製程製造一種具有高耐用度且能穩定操作於250伏特(或更高)之保險絲。 As described above, the surface of the present invention is attached to a fuse A manufacturing method that manufactures a fuse having high durability and stable operation at 250 volts (or higher) through a soldering process.
由上述說明可知,本發明揭露一種保險絲及其製造方法,因為使用較佳機械強度的陶瓷材料作為非導電性元件且使用陶瓷管,且使用銲接環接合陶瓷管和每一個密封電極,所以可以改善保險絲的耐用度。 As apparent from the above description, the present invention discloses a fuse and a method of manufacturing the same, which can be improved because a ceramic material having a better mechanical strength is used as the non-conductive member and a ceramic tube is used, and the ceramic tube and each sealing electrode are bonded using a welding ring. The durability of the fuse.
此外,本發明揭露一種保險絲及其製造方法,因為纏繞在非導電元件外表面的可熔元件具有足夠長度和足夠匝數,時間延遲特性可被改善,所以保險絲可穩定操作於高電壓。 Further, the present invention discloses a fuse and a method of manufacturing the same, since the fusible element wound on the outer surface of the non-conductive member has a sufficient length and a sufficient number of turns, and the time delay characteristic can be improved, so that the fuse can be stably operated at a high voltage.
此外,本發明揭露一種保險絲及其製造方法,因為在銲接接面有電鍍層,所以可以進一步改善濕潤特性和接合強度。 Further, the present invention discloses a fuse and a method of manufacturing the same, since the plating joint is provided with a plating layer, so that the wetting property and the joint strength can be further improved.
