Description of the invention: [Related application] The present application claims priority to Korean Patent Application No. 10-2010-0079506, filed on Jan. 17, 2010, and the benefit of 35u sc 119 All rights, the entire contents of this application are herein incorporated by reference. BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a repeatable fuse, and more particularly to a reproducible fuse having high reliability, in which an elastic member is used to break the circuit and prevent overheating. An overcurrent occurs in the circuit. [Prior Art] In general, all appliances that use electric power always have an accident due to an accident caused by abnormal overcurrent in the circuit or overheating due to external overheating. Conventionally, in order to prevent overheating, a disposable fuse made of a material which is melted and cut by heat generated when an overcurrent flows has been used. However, since the disposable fuse is not expensive but is no longer used, the disposable fuse should be replaced by a new disposable solution 4 after meltdown. This situation disadvantageously leads to large costs. To solve this problem, a bimetal thermal switch combined with two heterogeneous metal plates having different thermal expansion coefficients is used instead of the disposable fuse. However, the bimetal is thermally opened, having a problem that it only serves as a contact point and has a large operational deviation depending on the temperature, and an additional device such as a limit switch is required. Although polymer fuses using special polymers have been developed, polymer 4' has the following problems: the chemical nature of the material is unstable, and there is a sudden change in voltage and current of 201222613 39351pif due to explosion or The danger of similar people. In addition, the polymer fuse is unstable on (4) and has a low margin and a slow reaction time. This situation may lead to an emergency. At the same time, the surface of the printed circuit board is cracked, so that the electrical device recently requires a fuse that allows the surface to adhere. However, it is necessary to weld 27 Å for the process of the surface-adhesive disposable fuse. 〇 or a temperature of 270 ° C or higher, so the lysate is attributed to its intrinsic properties and thus surface adhesion is not possible. Of course, this problem is solved by the fact that it is difficult to make the switch surface-adhered due to its bulkiness and the possibility of deterioration due to the soldering temperature. To solve these problems, a shape memory alloy material is developed using a reusable surface-adhesive elastic member (for example, shape mem〇ry all〇y). g is a shape memory alloy with poor, so it provides reproducible with high reliability. If the shape is alloyed, the elastic auxiliary elongation and compression, the wealth may leave its original position or loose, and the peak can be connected and disconnected. .

The elastic member 5 has an end connected to the inner side of the outer casing 1GG to be electrically connected to the first lead terminal 2 (9), wherein the end of the embodiment of the miscellaneous member 5 (10) is connected to the inner bottom or the latch projection of the outer casing 100 12〇. Next, the other end of the elastic member 5A is connected to the side of the shaft 400 to be electrically connected to the shaft 4''. In this embodiment, the other end of the resilient member 500 is coupled to the support of the shaft 4〇〇. The elastic member 500 may preferably be formed of a conductive material, more preferably a shape memory alloy. The elastic member 5A composed of a plurality of members can be installed in the inner space of the outer casing 100. For example, the resilient member 5A includes a coiled first spring 510 and a coiled second spring 520, and the springs 51A and 520 are configured to surround the shaft 400. The first spring 51 can be defined in a portion below the inner space of the outer casing 100, that is, between the bottom of the outer casing and the support 410 of the shaft. The second spring 52A can be positioned in the upper portion of the inner space of the outer casing 1 , i.e., between the support 41 of the shaft and the latched dog 120 of the outer casing. Here, at least one of the first spring 510 and the second spring 520 may be made of a shape memory alloy. For example, the second spring 520 can be made of a shape memory alloy. 15 201222613 jjympif In addition, the elastic member 500 may include a plate spring having a plate shape so that the bending elasticity of the elastic material can be used (see Fig. 8). In this case, the elastic member 500 may include a first leaf spring 53A and a second plate spring 540. This embodiment illustrates a leaf spring 53 〇 or 54 〇 having a shape that is curved in the transverse direction of the elongation and compression directions of the leaf spring, that is, formed by a C-shaped or braided curved plate. The leaf spring 53A or 540' is as shown in Figures 7 and 8. The shape of the leaf spring is not limited to this and can be changed into a variety of shapes by which bendable elasticity can be used. The first leaf spring 530 and the second leaf spring 54A are positioned in parallel between the bottom of the shaft shed and the inner bottom of the outer casing 100. The first plate spring coffee and the second plate spring, 540 to > - can be made of a stainless steel-based projectile with excellent tension, for example 5, the first leaf spring 530 is made of a spring based on non-mineral steel The tension can be maintained according to the temperature, and the second plate spring = 40 is made of a metal having excellent conductivity (for example, copper) to electrically connect the external 10G and the shaft and support the shaft shed. Alternatively, the leaf spring can be shaped and configured to reduce the overall resistance value. ^ This embodiment illustrates that the elastic member 5 (10) includes a coil-like elastic crystal or a wire terminal: 发明 the invention is not limited thereto.

In addition, a fastener (not shown) can be used to fasten the elastic member to make it firm. The ground is fixed to the detachment prevention groove 110 (the outer casing groove 110a, the lock groove 11 〇 b, the branch groove service, and the deletion). Here, for example, the first spring 51 () and the second spring箸52〇 is configured as follows: • The second magazine of the shape memory alloy is assembled around the sleeve 400 in a compressed state and the money silver metal The first spring 51〇 can be assembled in a compressed state around the shaft 400. A certain level of tension is required for each spring 'where the tension of the first spring 51〇 is greater than the tension of the second elastic spring' then the first spring 51 The tension of the crucible can make the shaft 4〇〇 contact with the second lead terminal 300. At a certain level of current, the vehicle is electrically connected to the second lead terminal 3 by the tension of the first magazine 510. If the overcurrent flows 'the heat is applied to the spring. Specifically, when the heat is applied to the second magazine 52 of the shape memory alloy to increase the temperature above the transition (transformation) temperature, the second spring 520 is deformed. Therefore, the first magazine 510 is compressed by the elongation of the second spring 520 and connected to the shaft shed of the spring via the support 41 ,, and then moved in a direction away from the second lead terminal, thereby The second lead terminal 300 and the shaft 400 are disconnected from each other. If the elastic member 500 is composed of the first leaf spring 53 〇 and the second leaf spring 54 且 and the two springs are positioned parallel to each other in the inner bottom of the outer casing 100 and 17 201222613 jympif Between the bottom of the The detachment prevention groove i(10) can be formed so that the leaf springs 530 and 54 稳定 stabilize the outer casing without loosening. The bottom portion is formed to have a bottom portion of the outer shell red &#(9) and is formed to have a groove with the outer casing groove 110a. The groove 11Qe. Because the axial grooved chest has the same as in the aforementioned outer casing groove, as shown in Fig. 7 (4) and Fig. 7 (b), the two ends of the first plate are respectively placed in the outer casing groove and the shaft The first plate spring 530 and the second plate spring 540 are provided in the following manner, and the two plate springs 54G are connected to the bottom portion of the shaft and the bottom plate. It is on the outer casing groove u〇a and the shaft groove u〇e. Further, when the separation preventing groove is formed, both ends of the spring can be formed with the separation preventing portions 531a and 531b, and the separation preventing portions 531a and 531b can be attached to the separation preventing grooves 11a and 11Qe. The detachment preventing portion can be formed to protrude convexly from both ends of the leaf spring, as shown in Fig. 8(a). Alternatively, each of the detachment preventing portions may be detachably attached to the detachment prevention groove by being fitted into the detachment prevention groove, as shown in Fig. 8(b). If the elastic member 500 is composed of the leaf springs 53A and 54A, the leaf springs are also elongated or compressed in the same manner as the coil springs 51 and 520 described above, and thus the details thereof will be omitted. The repeatable fuse according to this embodiment may further include an insulator 13 to insulate the outer casing 100 from the second lead terminal 3, and the insulator 13 is disposed on the side of the outer casing 100 on which the second lead terminal 3 (10) is disposed.

When the field is provided with the insulator 130, one end of the elastic member 5 (9) may be fixed to the insulator 130, and the detachment prevention groove 110b is formed in the portion of the insulator 130 which is in contact with the elastic member 5A, for example, in the outer casing 110 (see image 3). The repeatable fuse according to this embodiment may further include a connecting wire 6〇 for connecting the bottom of the shaft 4〇〇 with the inner bottom of the casing 丨 (10). Since the connecting wire 6 is connected to the shaft 400 and the outer casing 100 and supports the shaft 400, even if the shaft 4 is moved by the elastic member 5, it is possible to reduce the piay or looseness of the v-axis 400. Further, if the connecting wire 600 is formed of a conductive material such as metal, the connecting wire 6 is electrically connected to the shaft 400 and the case 1b. The inner bottom of the outer casing 100 may further include a contact plate 7A. This contact plate, which is itself a thin metal plate, makes it easy to electrically contact the shaft 4 and the outer casing 1 to each other. If the contact plate 700 is provided, the connecting wire 600 may be connected to the inner bottom of the outer casing but to the contact plate. It has been explained in the foregoing that the detachment prevention groove 11 用于 for stably mounting the elastic members (the spring and the second spring) is formed in the outer casing 0 and the insulator 130 such that the respective detachment preventing grooves HQ are formed at the first The lower side of the spring 510 and the upper side of the second spring 520. However, the position of these detachment preventing grooves 110 can be varied variously. Further, although the detachment preventing groove 110 formed in the shaft is also illustrated as being formed in the support 41, the position of the detachment preventing groove 110 may be varied in the surface of the shaft 4''. Further, the shape of the detachment prevention groove 110 can also be varied variously as shown in Fig. 5(a) 19 201222613 jyjDipif to Fig. 5(f). Hereinafter, the operation of the repeatable fuse according to the present invention will be described with reference to the drawings. And Figure 6(b) shows a repeatable process in accordance with an embodiment of the present invention. Fig. 6(a) shows a state in which a certain current is applied, and Fig. 6(b) shows a state in which an overcurrent is applied. As shown in Fig. 6(a), the interaction between the tension of the first spring 51〇 and the second bolus 52 allows the shaft shed connected to the spring to be electrically connected to the second lead terminal lion. When a current of a value lower than the value is applied via the first lead terminal 200, the current flows to the pump 400 through the first spring 51 and the second spring 52〇 connected to the first lead terminal 200. In addition, since the shaft 4〇〇 is connected to the second lead terminal, the circuit is constructed such that the electrical test is performed to the electronic/electrical device. When an overcurrent higher than the reference value flows at the first lead terminal 2〇〇', is this overcurrent connected to the first lead terminal? The flow in the first spring 510 and the second spring 52G of 200 and then the resistance of each spring is introduced in the spring, thereby increasing the temperature. Specifically, when the heat is generated in the shape of the second spring 52 of the sheet metal, the second magazine returns to its original shape, that is, the elongated spring shape. As shown in FIG. 6(b), the second spring 52〇 is elongated and the vehicle is moved in the direction toward the first spring 510 due to the tension of the second magazine, thereby making the first The elastic cyanine 51 is compressed. Thus, the tension of the second spring 520 causes the shaft 400 to be disconnected from the second lead terminal 300 so that no current flows between the first lead terminal 200 and the second lead terminal 300 201222613 39351ρΐί. At this time, for the foregoing operation, preferably, the tension of the second spring is smaller than the tension of the first spring 510 when the second spring 520 has a temperature lower than the transition (transformation) temperature, and has a flaw in the second spring 52 The tension of the second spring 52〇 is greater than the tension of the first spring 510 at the temperature of the transition (transformation) temperature. Thereafter, the disconnection between the shaft 400 and the second lead terminal 3A causes current not to flow in the second spring 520, so that the temperature of the second spring 52 is lowered. As the temperature decreases, the tension disappears in the second magazine 52〇, and = the disappearance of the force causes the second (four) 520 to retract by the tension of the first magazine|51〇. Therefore, the shaft is moved and then electrically connected again to the second lead terminal 300. Thus, the first spring 510 and the second spring 520 are repeatedly elongated and compressed. The two ends of the first spring 510 are respectively supported by the outer casing to prevent the groove UOa and the first supporting groove u〇c of the support 410, so that the first spring | 510 repeatedly elongates and shrinks but the first The 菁 〇 51〇 does not leave its original position or is not loose. The two ends of the second spring 52() are also detached from the outer (four) 防止 to prevent the groove from secreting the second support groove llGd of the support member 41', so that the second spring (10) is repeatedly elongated and compressed. However, the second section of the 52G alone is pure or not loose. = It seems that the stipulations only make some of the technical nucleus of the nucleus, and it is easy to see '(4) The technology inferred by the technologist is in the second saga = (10) specific implementation and each secret modification will be included in the protection scope of the present invention. . 4 [Simple description of the drawings] 201222613 3935 lpif Fig. 1 is a view showing a repeatable snagging through the embodiment of the present invention. 2 and 3 are cross-sectional views illustrating a repeatable dissolution wire in accordance with an embodiment of the present invention.
