Abstract

The purpose of the present invention is to have a temperature fuse capable of providing low resistance when conducting electricity and having no melting problem on the movable electrode (4) and the leading line (2) even when the machine temperature of the connecting temperature fuse is increased slowly. Thus, for the invented temperature fuse, the load of compressed spring (9) is eliminated when temperature sensitive material (7) is operated and is melted due to temperature; additionally, the movable electrode (4), which is compressed and contacted by the compressed spring (9) due to the stretch of compressed spring (9), can be separated from the leading wire (2) so as to terminate the current. The invention is featured with the followings. The movable electrode (4) is obtained from an alloy after it is undergone with an internal oxidization treatment, in which the alloy is composed of 100 weighting parts containing 99 to 80 weighting parts of Ag (silver) and 1 to 20 weighting parts of Cu (copper). The thickness of the pretty thin oxide layer on the material surface is smaller than 5 μm, and the average particle diameter of the oxide particles in the material is 0.5 to 5 μm.

Fig. 1 is a normal cross-sectional view of the silk refining of w and w J, and Fig. 2 is a cross-sectional view after the actuation. As shown in the figure, the temperature β is composed of the main β metal box i, the lead wires 2, 3, the insulating milk circle 1 and the shrinking spring 8'9, the movable electrode 4 and the temperature sensing material 7. Among them, the pole 4 is one side of which is in contact with the inside of the metal case 1 having conductivity, and it is known that the side is moved. There is a compression spring 8 between the movable electrode 4 and the insulating material 5, and there is a compression spring 9 between the movable electrode 4 and the temperature-sensitive material 7 ^ Common compression springs 8,9 maintain their compression state 'and because the compression ratio of the compression spring 9 is compressed The spring 8 is strong, so the movable electrode 4 is attached to the insulating material 5 side and is crimped to the lead 2. Therefore, the leads 2, 3 are connected to the wiring of an electronic device or the like, and the current is transmitted from the lead 2 to the movable electrode 4, the metal box 1, and then to the lead 3 to be energized. Organic materials such as adipic acid (or fatty acid) with a melting point of 150 ° C can be used as the temperature sensing material. When the predetermined operating temperature is reached, the temperature-sensitive material 7 will soften or melt, and due to compression

彈簧9之負荷而產生變形。如此接續著溫度熔絲之電子機器等由於過熱而達到既定之作動溫度，則感溫材7產生變形，並消除壓縮彈簧9之荷重，而對應於壓縮彈簧9之伸張，壓縮彈簧8之壓縮狀態便會解放而如圖2所示伸長使得可動電極4與引線2分離’而成斷電狀態。若將具有此種機能之溫度熔絲接續於電子機器等之配線’便可事前防止因The load of the spring 9 causes deformation. In this way, the electronic equipment such as the temperature fuse is overheated to reach a predetermined operating temperature, the temperature sensing material 7 is deformed and the load of the compression spring 9 is eliminated, and the compression spring 9 corresponds to the extension of the compression spring 9 and the compression state of the compression spring 8. It will be released and stretched as shown in FIG. 2 so that the movable electrode 4 is separated from the lead 2 and becomes a power-off state. If a temperature fuse with such a function is connected to the wiring of an electronic device, etc., it is possible to prevent the cause in advance.

Description of the invention (2) Damage and fire of the machine body caused by overheating of the machine. But there will be a problem with this construction. If the temperature of the machine that connects the temperature-dissolving wire rises rapidly, the temperature-sensitive material 7 will melt and deform rapidly, so the lead wire 2 and the movable electrode 4 will be rapidly separated. On the contrary, when the temperature rises slowly, the temperature-sensing material 7 is slowly melted and deformed. Therefore, the separation of the lead 2 and the movable electrode 4 proceeds slowly. As a result, it is easy to cause a local minute arc between the lead 2 and the movable electrode 4, and this arc will cause the movable electrode $ and the lead 2 to dissolve, so that the function of the temperature fuse cannot be fully exerted. For example, when Ag-Cd〇 is selected as the material of the movable electrode 4, although Ag-Cd〇 has the advantage of low resistance and high thermal conductivity, if an arc occurs between the lead 2 and the movable electrode 4, the vapor pressure of Cd0 is high. Therefore, due to the arc, the valley is easily deformed at 30% to 20%, which causes the problem that the movable electrode 4 and the lead 2 are mutually> valley. , ... ί "questions can be added by increasing the Cd0 content in Ag-Cd0 and adding two == Cd〇 content, then the contact resistance with the lead 2 will increase, and the problem of the low w sound of the contact part will easily occur. If the temperature rises, the material of the movable electrode 4 in the temperature-dissolving part uses Ag alloy ^ cloth, and if the oxide in the f oxide material is fine particles, there is a problem of incompatibility, but the oxide is regarded as particles and resistance is generated. Will increase, and with the increase of the temperature of the contact part, the problem of the low contact fuse performance of the U2 connection will occur. Therefore, "the purpose of the present invention is to make the connection even if the connection is continued. The temperature of the fuse is rising slowly

Description of the invention (5) The performance of temperature spinning is low. The material of the movable electrode 4 of the present invention is obtained by internalizing an alloy containing Ag & Cu. The so-called internal oxidation treatment is a state in which the surface of the metal is selectively oxidized when oxygen is diffused from the surface of the alloy to the inside when the alloy is exposed to high temperature during the mounting of sufficient oxygen. Since Ag and Cu alloys are internally oxidized, Cu is selectively oxidized, and Cu is produced in the alloy as an oxide. In this book: In addition to the alloy of Ag_Cu0, the material of the movable electrode is used to make the field spleen Ag and Cu alloy subject to internal oxidation treatment under specified conditions, so the thickness of the thin oxide layer on the surface of this material can be reduced. Below 5um, and the average particle size of the material particles on the material can reach 0.5 ~ 5um, so there is no melting problem even if the temperature is blocked, and it can provide the low temperature of $ ^ when the current is turned on. The material of the "Soluble" movable electrode can be obtained from Sn or In & ^ "all kinds of alloys. Due to the combination of Sn and In, etc .: (Cu_Sn) 0x, (Cu_In) 0x, (Cu-Sn_In) 0x The local resistance improves the resistance to local micro-arc that occurs between the lead and the movable electrode.
