[0048] Wherein, the preprocessing includes punching and / or cutting.

[0049] In a specific implementation, the metal embryo can be in any shape as long as it can eventually be made into the target melt 20. For example, a rectangular metal embryo is cut and / or punched to make the rectangular metal embryo reach a size corresponding to a preset specification.

[0050] Step S2012 , bending the initial melt 110 to obtain a target melt 20 .

[0051] The target melt 20 includes a first connection part 221-1, a second connection part 221-2, a fuse part 222, a first electrode 21-1 and a second electrode 21-2. The first end of the fuse part 222 has a first connection part 221-1 extending in a direction perpendicular to the cavity opening and parallel to the first side of the shell, and the first connection part 221-1 is used to connect with the first electrode 21-1; the second end of the fuse part 222 has a second connection part 221-2 extending in a direction perpendicular to the cavity opening and parallel to the first side of the shell, and the second connection part 221-2 is used to connect with the second electrode 21-2; the fuse part 222 is a left-right symmetrical structure, and the two sides of the symmetrical structure respectively take the intersection of the symmetrical structure as the starting position, and the height gradually decreases or increases in the direction of the first connection part 221-1 and the second connection part 221-2 corresponding to the two sides. The target melt 20 is a metal target melt.

[0052] In a specific implementation, it can be understood that the initial melt 110 obtained by pretreatment may include an electrode, that is, it is integrally formed with the electrode; the initial melt 110 may also not include an electrode, that is, it is a separate component from the electrode.

[0053] The following describes the one-piece molding and the discrete molding separately.

[0054] Embodiment 1

[0055] In one possible embodiment, see Figure 3 The method of bending the initial melt 110 to obtain the target melt 20 includes: performing a first bending process on the initial melt 110 to obtain a first melt 120; fixing the first melt 120 according to the first clamping portion 223-1 and the second clamping portion 223-2; performing a second bending process on the fixed first melt 120 to form a fuse portion 222 to obtain the target melt 20.

[0056] In the specific implementation, Figure 7 As shown in FIG. 1 , in this embodiment, the initial melt 110 formed in one piece is subjected to a bending process to finally obtain the target melt 20. Specifically, the initial melt 110 is subjected to a first bending process to obtain the target melt 20. Figure 4 The first melt 120 shown in the figure includes a first electrode 21 - 1 and a second electrode 21 - 2 , wherein the first electrode 21 - 1 includes a first fixing portion and a first clamping portion 223 - 1 , and the second electrode 21 - 2 includes a second fixing portion and a second clamping portion 223 - 2 .

[0057] Specifically, the fixed first melt 120 is subjected to a second bending process to obtain the target melt 20, including: bending the fuse portion 222 of the first melt 120 into an arc, wherein the angle of the arc is greater than 0° and less than or equal to 180°; or, bending the fuse portion 222 of the first melt 120 into a V-shape, wherein the vertex angle of the V-shape is greater than 0° and less than or equal to 180°.

[0058] For specific implementation, see Figure 5 and Figure 6 After obtaining the first electrode 21-1 and the second electrode 21-2, the first melt 120 is subjected to a second bending process; and the second bending process may also include multiple processes, such as bending in a direction of forming a cavity inwardly of the shell to form a Figure 5 As shown in the fuse part 222, the target melt 20 is obtained; for example, the shell is bent in the opposite direction of the cavity to form a cavity, so as to form a Figure 6 The fuse part 222 shown is formed, and then the target melt 20 is obtained. First, the first melt 120 is clamped and fixed by a clamp, and then the fixed first melt 120 is pressed by a stamping device to obtain the fuse part 222 of a preset size and shape.

[0059] Furthermore, since the V-shaped fuse portion 222 may generate tip discharge, the top angle of the V-shape may be set to a rounded angle to eliminate the tip discharge.

[0060] Please also read Figure 1 , when assembled with the shell, the first fixing portion extends along the first side of the shell, out of the shell, bends around the first side end of the shell, and fits with the first side end of the shell; the second electrode 21-2 includes a second fixing portion, which, when assembled with the shell, extends along the second side of the shell, out of the shell, bends around the second side end of the shell, and fits with the first side end of the shell.

[0061] In a possible embodiment, after the initial melt 110 is bent to obtain the target melt 20, the method further includes: pressing a first protrusion on the first connection portion 221-1 of the target melt 20, the first protrusion being used to cooperate with the first groove on the shell; pressing a second protrusion on the second connection portion 221-2 of the target melt 20, the second protrusion being used to cooperate with the second groove on the shell.

[0062] In a specific implementation, after obtaining the target melt 20, a first convex portion can be pressed out on the first connection portion 221-1 of the target melt 20, and a second convex portion can be pressed out on the second connection portion 221-2. The first convex portion and the second convex portion can be of any shape, and the matching connection between the first groove and the second groove can be of any form, which is not limited here. In addition, the positions of the first convex portion and the first groove can be interchangeable, for example, the first convex portion is arranged on the shell, and the first groove is arranged on the first connection portion 221-1; similarly, the positions of the second convex portion and the second groove can also be interchangeable.

[0063] Embodiment 2

[0064] In a possible embodiment, after the metal embryo is cut, a first electrode 21-1, a second electrode 21-2 and the initial melt 110 are obtained; before the initial melt 110 is bent to obtain the target melt 20, the method further includes: opening a first connecting groove in the first electrode 21-1, and the first connecting groove is used to connect to the first connecting part 221-1; and opening a second connecting groove in the second electrode 21-2, and the second connecting groove is used to connect to the second connecting part 221-2.

[0065] In the specific implementation, Figure 7 As shown, after the metal embryo is cut, three separate parts are obtained, namely, the first electrode 21-1, the second electrode 21-2 and the initial melt 110. Specifically, a first connecting groove is first opened in the first electrode 21-1, and a second connecting groove is opened in the second electrode 21-2. Then, the initial melt 110 is subjected to a bending process. Specifically, the bending process of the initial melt 110 to obtain the target melt 20 includes: performing a first bending process on the initial melt 110 to obtain the first melt 120; fixing the first melt 120 according to the first clamping portion 223-1 and the second clamping portion 223-2; performing a second bending process on the fixed first melt 120 to form the fuse portion 222 to obtain the target melt 20.

[0066] Among them, the first fuse 120 includes an initial fuse part, the first electrode 21-1 includes a first fixing part and a first clamping part 223-1, and the second electrode 21-2 includes a second fixing part and a second clamping part 223-2; in the state of being assembled with the shell, the first fixing part extends out of the shell along the first side of the shell, bends around the end of the first side of the shell, and fits with the end of the first side of the shell; the second electrode 21-2 includes a second fixing part, and in the state of being assembled with the shell, the second fixing part extends out of the shell along the second side of the shell, bends around the end of the second side of the shell, and fits with the end of the first side of the shell.

[0067] It is understandable that the bending method of the fuse portion 222 is consistent with that in the first embodiment, and will not be described in detail here.

[0068] Furthermore, after the initial melt 110 is bent to obtain the corresponding fuse portion 222, the first connection grooves and the second connection grooves of the first electrode 21-1 and the second electrode 21-2 can be connected to the first connection portion 221-1 and the second connection portion 221-2 on the initial melt 110 to assemble a complete target melt 20.

[0069] Step S2013: Assemble the target fuse 20 with the prepared shell to obtain an initial fuse.

[0070] One side of the shell is recessed inward to form a cavity, and the melt is arranged in the cavity; the first electrode 21-1 extends out of the shell along the first side of the shell, and the second electrode 21-2 extends out of the shell along the first side of the shell. The shell 10 can be a ceramic shell or a shell 10 made of other materials, which is not limited here.

[0071] In a possible embodiment, the target melt 20 is assembled with a prepared shell to obtain an initial fuse, including: coating a colloidal material on the inner walls of the first side and the second side of the shell; placing the target melt 20 in the cavity, and fitting the first connection portion 221-1 of the target melt 20 with the colloidal material on the first side, and fitting the second connection portion 221-2 of the target melt 20 with the colloidal material on the second side, to obtain the initial fuse.

[0072] In a specific implementation, coating the inner walls of the first side and the second side of the shell with colloidal material will form a first sealing layer and a second sealing layer respectively. The first sealing layer can not only make the first connection part 221-1 and the second connection part 221-2 of the target melt 20 adhere to the shell, but also enhance the sealing of the fuse.

[0073] Step S2014: Fill the shell with arc extinguishing material 30 to obtain a first fuse.

[0074] Step S2015: Apply sealing material to the cavity opening of the shell of the first fuse.

[0075] In a specific implementation, coating the sealing material at the cavity opening of the shell will form a third sealing layer, which can not only seal the arc extinguishing material 30 and the target melt 20 in the shell, but also enhance the sealing of the first fuse.

[0076] Step S2016: solidify the sealing material to obtain a target fuse.

[0077] Among them, the target fuse is as follows Figure 4 As shown, it includes a shell 10, a target melt 20, an arc extinguishing material 30, a first sealing layer 51, a second sealing layer 52, and a third sealing layer 40. The target melt 20 includes a first connecting portion 221-1, a second connecting portion 221-2, and a fuse portion 222; wherein, the target melt 20 may also include a first electrode 21-1 and a second electrode 21-2, or the first electrode 21-1 and the second electrode 21-2 are separately arranged from the target melt 20, which is not limited here.

[0078] It can be seen that in the present application, by obtaining the processing instructions for the fuse, the following processing is performed according to the processing instructions: the metal blank is pre-processed to obtain an initial melt of preset specifications; the initial melt is bent to obtain a melt; the melt is assembled with a prepared shell to obtain an initial fuse; the arc extinguishing material 30 is filled in the shell to obtain a first fuse; a sealing material is coated on the cavity opening of the shell of the first fuse; and the sealing material is cured to obtain a target fuse. A fuse is obtained by the preparation method, wherein the melt comprises a connection part, a fuse part, a first electrode and a second electrode, the first end of the fuse part has a first connection part extending in a direction perpendicular to the cavity opening and parallel to the first side of the shell, the first connection part is used to connect with the first electrode; the second end of the fuse part has a second connection part extending in a direction perpendicular to the cavity opening and parallel to the first side of the shell, the second connection part is used to connect with the second electrode; the fuse part is a left-right symmetrical structure, the two sides of the symmetrical structure take the intersection of the symmetrical structure as the starting position, and the height gradually decreases or increases in the direction of the first connection part and the second connection part corresponding to the two sides; when the fuse part is blown, the melt at both ends after being blown is quickly separated, combined with the rapid blocking of the arc extinguishing material 30, the arc extinguishing speed is improved, and then the breaking capacity of the fuse is improved.

[0079] The above mainly introduces the scheme of the embodiment of the present application from the perspective of the execution process on the method side.

For example, each functional unit can be divided according to each function, or two or more functions can be integrated into one processing unit. The above integrated unit can be implemented in the form of hardware or in the form of software functional units. It should be noted that the division of units in the embodiment of the present application is schematic and is only a logical function division. There may be other division methods in actual implementation.

[0098] In one possible embodiment, Figure 4 As shown, the fuse obtained by the above-mentioned preparation method includes a shell 10 and a target melt 20, one side of the shell 10 is recessed inward to form a cavity, the target melt 20 is arranged in the cavity, and the cavity is filled with an arc-extinguishing material 30; wherein the target melt 20 includes a connecting portion and a fuse portion 222, the first end of the fuse portion 222 has a first connecting portion 221-1 extending in a direction perpendicular to the cavity opening and parallel to the first side of the shell 10, the first connecting portion 221-1 is used to connect to the first electrode 21-1; the second end of the fuse portion 222 has a first connecting portion 221-1 extending in a direction perpendicular to the cavity opening and parallel to the first side of the shell 10, the first connecting portion 221-1 is used to connect to the first electrode 21-1; the second end of the fuse portion 222 has a first connecting portion 221-1 extending in a direction perpendicular to the cavity opening and parallel to the first side of the shell 10, A second connection part 221-2 is parallel to the first side of the shell 10, and the second connection part 221-2 is used to connect with the second electrode 21-2; the first electrode 21-1 extends out of the shell 10 along the first side of the shell 10, and the second electrode 21-2 extends out of the shell 10 along the second side of the shell 10; the fuse part 222 is a left-right symmetrical structure, and the two sides of the symmetrical structure take the intersection of the symmetrical structure as the starting position, and the height gradually decreases or increases in the direction of the first connection part 221-1 and the second connection part 221-2 corresponding to the two sides; the arc extinguishing material 30 wraps the fuse part 222.

[0099] In a specific implementation, the fuse in the embodiment of the present application is a chip fuse, which has a shell 10 with an opening on one side and a cavity, and the cavity is in the shape of a groove; the shell 10 can be a ceramic shell or a shell made of other materials, and can be made of ceramic materials such as alumina, zirconia, cordierite, and mullite. The fuse also has a target melt 20, which is placed in the shell 10, and the electrodes (first electrode 21-1 and second electrode 21-2) connected to the two ends (first end and second end) of the target melt 20 are fixed by the shell 10 to support and limit the target melt 20 and the electrodes. The target melt 20 is a melt, which can be made of metals such as copper and tin, or made of alloys, which are not limited here.

[0100] Furthermore, the fuse part 222 of the target fuse 20 is set to a bilaterally symmetrical structure, and the two sides of the symmetrical structure take the intersection of the symmetrical structure as the starting position, and gradually decrease or increase in height toward the first connection part 221-1 and the second connection part 221-2 corresponding to the two sides. Such a setting method can make the two sides of the fuse part 222 separate quickly when the fuse part 222 is blown, thereby improving the breaking speed of the fuse.

[0101] Specifically, the fuse portion 222 is bent into an arc shape in the concave direction of the housing 10; or, the fuse portion 222 is bent into an arc shape in the opposite direction of the concave direction of the housing 10.

[0102] The fuse portion 222 of the target melt 20 is designed in an arc shape, such as Figure 5 As shown, when the fuse portion 222 is bent into an arc shape in the concave direction of the housing 10, the height gradually increases from the midpoint of the arc to both ends along the concave direction of the housing 10; Figure 6As described above, when the fuse part 222 is bent into an arc in the opposite direction of the concave direction of the shell 10, the height gradually decreases from the midpoint of the arc to the two ends in the direction relative to the concave direction of the shell 10. In this shape, when the fuse part 222 is blown under an external abnormal current, the arcs generated at both ends of the blown part of the fuse part 222 will quickly move away as the target melt 20 burns. Since the arc extinguishing material 30 completely wraps the target melt 20, when the fuse part 222 burns, a step-like height change will occur. During the height change, the arc will be blocked by the arc extinguishing material 30 to achieve the arc extinguishing effect. If the two ends of the blown part need to re-generate an arc connection, the arc extinguishing material 30 blocking the surrounding of the blown part needs to be re-breakdown. There is no fixed arc burning channel, so the breaking capacity of the product is greatly improved. At the first moment when the fuse part 222 burns, an arc is generated based on the channel of the target melt 20 itself. When the target melt 20 burns to the second moment, the two ends of the fuse are stepped apart, so that the two ends of the fuse are blocked by the arc extinguishing material 30 and the circuit cannot be generated. Therefore, the electrical connection is disconnected, achieving the effect of rapid arc extinguishing and improving the breaking capacity of the fuse.

[0103] Among them, the filling material is mainly wrapped around the target melt 20, which plays the role of reducing the temperature rise during normal use of the product and quickly extinguishing the arc when the product is abnormally melted. It is mainly composed of quartz sand, melamine, melamine formaldehyde resin, aluminum hydroxide, magnesium hydroxide, talcum powder and other ingredients.

[0104] In a possible embodiment, the fuse part 222 is bent into a V-shape in the concave direction of the housing 10; or, the fuse part 222 is bent into a V-shape in the opposite direction of the concave direction of the housing 10. In this embodiment, the fuse part 222 can also be set to a V-shape, and the "V" shape is also a left-right symmetrical structure, and can also produce a step-by-step rise or fall state when the fuse is blown, thereby achieving the effect of rapid arc extinguishing and improving the breaking capacity of the fuse. It can be understood that the principle of this embodiment is the same as that of the arc structure, and it will not be repeated here.

[0105] Specifically, the arc angle is greater than 0° and less than or equal to 180°; the apex angle of the V-shape is greater than 0° and less than or equal to 180°. Preferably, when the fuse portion 222 is an arc, the preferred arc angle is 180°, which can make the separation speed of the two ends of the fuse faster; when the fuse portion 222 is a V-shape, the preferred apex angle is an acute angle, that is, 0° to 90°, which can make the separation speed of the two ends of the fuse faster. It can be understood that the specific vertex angle setting can be set according to the size of the fuse. When the fuse size is small, if the vertex angle is too small, the arc extinguishing material 30 at the inner angle near the vertex will be thinner, which is easy to be broken through by the arc and affect the arc extinguishing effect; when the fuse size is large, if the vertex angle is large, the separation speed of the fuse will be slowed down; it can be seen that a reasonable vertex angle needs to be set according to the size.

[0106] In a possible embodiment, a first sealing layer 51 is disposed between the first connecting portion 221 - 1 and the housing 10 ; and a second sealing layer 52 is disposed between the second connecting portion 221 - 2 and the housing 10 .

[0107] In a specific implementation, long-term use may cause internal aging of the fuse, resulting in the target melt 20 or the electrode falling off. In order to avoid this situation, in this embodiment, a first sealant is set on the inner wall of the cavity on the first side of the shell 10, and a second sealant is set on the inner wall of the cavity on the second side, so that the connection between the shell 10 and the target melt 20 can be glued together by the sealant to reduce the risk of falling off.

[0108] Furthermore, a third sealing layer 40 is provided at the cavity opening of the housing 10, and the second sealing layer 52 is used to seal the sealing material and the fuse 222 in the cavity. The third sealing layer 40 is used to seal the cavity opening of the housing 10, on the one hand to protect the performance of the target melt 20 from being affected by external environmental factors, and on the other hand to prevent the target melt 20 from falling off from the housing 10 when the internal pressure of the product increases. The first sealing layer 51, the second sealing layer 52 and the third sealing layer 40 are made of sealing materials, and the sealing materials can be one or more of epoxy resin, silicone resin, polyimide resin, and high-temperature silica gel. The sealing materials used in the first sealing layer 51, the second sealing layer 52 and the third sealing layer 40 can be the same or different.

[0109] Furthermore, a silicone rubber sheet is pasted on at least two side surfaces between the inner side of the shell 10 and the connection part between the target melt 20. The silicone rubber sheet has a backing adhesive and has a thickness of 0.2mm~1.0mm, for example, a thickness of 0.5mm. The pasting surface of the silicone rubber sheet includes at least 1 / 3 and above of the upper part of the shell 10. Its main function is to prevent the filling material inside the shell 10 from flowing out along the gap between the connection part of the target melt 20 and the inner wall of the shell 10, resulting in poor appearance and performance. It can also buffer the impact of explosion pressure on the shell 10, thereby improving the breaking ability of the product.

[0110] The third sealing layer 40 is used to seal the top surface of the shell 10. On the one hand, it protects the performance of the target melt 20 from being affected by external environmental factors. On the other hand, when the internal pressure of the product increases, it prevents the target melt 20 from falling off from the shell 10. It is obtained by curing silicone resin at high temperature.

[0111] Furthermore, the filling material and the sealing material can be mixed in an appropriate proportion to form a new filling material, which can be solidified at a certain temperature and wrapped around the target melt 20 to play an arc extinguishing role, thereby reducing the difficulty of the product production process.

[0112] Furthermore, in order to enhance the stability of the connection between the target melt 20 and the shell 10, a first protrusion is extended from the first connection point between the first connection portion 221-1 and the fuse portion 222, and a first groove adapted to the first protrusion is provided on the first side of the shell 10; a second protrusion is extended from the second connection point between the second connection portion 221-2 and the fuse portion 222, and a second groove adapted to the second protrusion is provided on the second side of the shell 10.

[0113] In a specific implementation, since the target melt 20 is made of metal, when the target melt 20 is placed in the shell 10, the first convex portion retracts due to the extrusion of the first side of the shell 10, and when the first convex portion reaches the position of the first groove, the first convex portion pops out and combines with the first groove, so that the target melt 20 and the shell 10 are fastened, thereby enhancing the stability of the connection between the target melt 20 and the shell 10. Similarly, the combination principle of the second convex portion and the second groove is consistent with the combination principle of the first convex portion and the first groove, which will not be repeated here.

[0114] In a possible embodiment, the volume of the fuse part 222 gradually decreases from the first connection point and the second connection point to the symmetrical point. Specifically, the fuse part 222 is set to gradually decrease toward the symmetrical point, so that the fuse position can be limited to the vicinity of the symmetrical center point, so that the gradient shape of the fuse part 222 is set to better play an arc extinguishing role.

[0115] In a possible embodiment, the first electrode 21-1 extends along the first side of the shell 10, the first fixed portion outside the shell 10 is bent around the first side end of the shell 10, and is fitted with the first side end of the shell 10; the second electrode 21-2 extends along the second side of the shell 10, the second fixed portion outside the shell 10 is bent around the second side end of the shell 10, and is fitted with the first side end of the shell 10; a third protrusion is provided on the first fixed portion, and a third groove matching the third protrusion is provided on the first side of the shell 10; a fourth protrusion is provided on the second fixed portion, and a fourth groove matching the fourth protrusion is provided on the second side of the shell 10.

[0116] In a specific implementation, the first electrode 21-1 is bent and fitted around the end of the first side of the shell 10, so that the first electrode 21-1 is connected to the shell 10. A colloid can also be coated on the part where the electrode and the shell 10 are fitted to increase the adhesion strength. In addition, a third protrusion can be provided on the first electrode 21-1, and a third groove can be provided on the first side of the shell 10. When the target melt 20 and the shell 10 are assembled, the third protrusion and the third groove are matched and connected, so that the first electrode 21-1 is buckled on the first side of the shell 10, further enhancing the stability of the connection between the first electrode 21-1 and the shell 10. Similarly, the fourth protrusion provided on the second electrode 21-2 is matched and connected with the fourth groove on the second side of the shell 10, so that the second electrode 21-2 is buckled on the second side of the shell 10, further enhancing the stability of the connection between the second electrode 21-2 and the shell 10.

[0117] In a possible embodiment, the first electrode 21-1 is provided with a first connecting groove adapted to the connecting part, and the first connecting part 221-1 is connected to the first electrode 21-1 through the first connecting groove; the second electrode 21-2 is provided with a second connecting groove adapted to the connecting part, and the second connecting part 221-2 is connected to the second electrode 21-2 through the second connecting groove.

[0118] In a specific implementation, the first electrode 21-1 and the target melt 20 can be integrally formed or separately connected. In this embodiment, the first electrode 21-1 and the target melt 20 are two components that are separately connected. A connecting groove is provided on the first electrode 21-1. The first connecting portion 221-1 of the target melt 20 is inserted into the first connecting groove, so that the first connecting portion 221-1 is engaged with the first connecting groove, so that the target melt 20 is connected to the first electrode 21-1. Similarly, the second connecting portion 221-2 of the target melt 20 is inserted into the second connecting groove in the second electrode 21-2, so that the second connecting portion 221-2 is engaged with the second connecting groove, so that the target melt 20 is connected to the second electrode 21-2. In addition, the first electrode 21-1 and the first connecting portion 221-1, and the second electrode 21-2 and the second connecting portion 221-2 can also be connected by colloid.

[0119] This arrangement allows the electrode and the target melt 20 to be manufactured separately, reducing production difficulty.

[0120] In one possible embodiment, Figure 7 As shown, a first clamping portion 223-1 is provided on the first connection portion 221-1, and a second clamping portion 223-2 is provided on the second connection portion 221-2; the first clamping portion 223-1 and the second clamping portion 223-2 are both used to fix the fuse portion 222 when the fuse portion 222 is pressed into an arc shape.

[0121] In a specific implementation, a clamping portion may be provided on the electrode during the preparation of the integrally formed electrode and the target melt 20. Furthermore, a clamping portion may be appropriately added between the connecting portion of the target melt 20 and the fuse portion 222 to reduce the difficulty of bending the target melt 20. The clamping portion may be in a horizontal, inclined or arc shape to play a transition role.

[0122] In a possible embodiment, the fuse part is provided with a segmented structure, and the segmented structure is used to cut off the connection between two ends of the fuse part when the fuse part 222 is blown.

[0123] In a specific implementation, a separation structure can be set on the fuse part 222. When the fuse part 222 blows, the separation structure is triggered so that the separation structure blocks the two ends of the fuse, thereby isolating the arcs at both ends of the fuse, achieving the effect of quickly extinguishing the arc, and further improving the segmentation capacity of the fuse.
