摘要： A thermal cutoff at least includes a current-carrying fusible element (104, 204, 312, 404, 504, 604) having two ends connected to a first electrode (107, 207, 308, 408, 508, 607) and a second electrode (108, 208, 309, 409, 509, 608), respectively. The current-carrying fusible element is provided in a closed cavity bounded by a housing (101, 201, 301, 401, 501, 601) having an opening at one end, a cover plate (102, 202, 302, 402, 502, 602), and a sealant (103, 203, 304, 403, 503, 603). The thermal cutoff further includes a first lead wire (109, 209, 310, 412, 512, 609) and a second lead wire (110, 210, 311, 413, 513, 610) each wrapped by an insulating sheath. One end of the first lead wire and one end of the second lead wire are electrically connected to the first electrode and the second electrode, respectively. The sealant is filled in the opening of the housing, at least covers an electrical joint between the first lead wire and a first electrode plate and an end of the first lead wire, and also covers an electrical joint between a second electrode plate and the second lead wire and an end of the second lead wire. The thermal cutoff exhibits excellent sealing protection performance, and is thus applicable to corresponding scenarios.

摘要： A thermal cutoff includes a first fusible element, a second fusible element, and a closed cavity bounded by a housing (101) having an open end, a cover plate (102), and a sealant (103). The two ends of the first fusible element and the two ends of the second fusible element are connected in parallel to a first electrode and a second electrode, respectively. The first fusible element and the second fusible element are provided in the closed cavity. A direction extending from a closed end to the open end of the housing (101) is defined as a vertical direction. The first fusible element and the second fusible element are vertically arranged. By means of the foregoing technical solutions, the thermal cutoff has a vertical configuration and thus in its entirety has an elongated shape to meet corresponding application requirements.

摘要： A high-voltage fusing apparatus includes a current fuse, a temperature fuse, and a current-carrying fuse. The current fuse is connected in series with the temperature fuse, and a series branch of the current fuse and the temperature fuse is connected in parallel with the current-carrying fuse. A resistance value of the current-carrying fuse is less than a resistance value of the current fuse, and a fusing temperature of the current-carrying fuse is lower than a fusing temperature of the temperature fuse. The high-voltage fusing apparatus of the present invention can cut off a high-voltage circuit quickly, and effectively protect the high-voltage heating circuit from overheating.

摘要： The present application relates to the field of protectors, particularly to a temperature fuse, which changes the traditional transmission manner of direct contact between a push rod and a temperature-sensing body. After improvements, a spring mechanism is added between the push rod and the temperature-sensing body to realize an indirect transmission between the push rod and the temperature-sensing body. Specifically, the spring mechanism includes springs and a spring column, the springs are sleeved at one end of the spring column, and when the temperature fuse is not triggered, the springs are in the state of compression. The temperature-sensing body abuts the other end of the spring column. One end of a push rod abuts a spring leaf, and the other end of the push rod abuts the end of the side wall of the spring column. The length of the temperature-sensing body in the expansion direction of the springs is greater than or equal to the length of the push rod abutting the spring column in the expansion direction of the springs. When the temperature-sensing body is triggered, a compression force of the springs is released, such that the other end of the push rod is separated from the spring column. Then the spring leaf is separated from the contact point under the action of its elastic force to cut off the circuit. The structure is used to overcome the problem of poor electrode contact caused by the aging of the temperature-sensing body.

摘要： A high-voltage direct-current temperature fuse at least comprises a high-voltage low-current temperature fuse (300) connected to a high-voltage direct-current circuit. The high-voltage low-current temperature fuse comprises a casing (301), fusible alloy wires (303) encapsulated in the casing and two pins (306, 307) extending out of the casing, wherein the fusible alloy wires are connected between the two pins. One of the pins is sequentially sleeved with an arc extinguishing sleeve (304) and a spring (305). One end of the arc extinguishing sleeve is in contact with the fusible alloy wires; and the other end of the arc extinguishing sleeve is in contact with the spring. One end of the spring is connected to the inner end face of the casing; and the spring is in a compressed state. The high-voltage direct-current temperature fuse further comprises a conventional temperature fuse (100) connected in parallel with the high-voltage low-current temperature fuse; or further comprises a current fuse (200) connected in series with the high-voltage low-current temperature fuse. The high-voltage direct-current temperature fuse solves the problem of timely arc cutting-off and can be directly applied to a high-voltage direct-current circuit.
