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.

摘要： The present invention discloses a thermal fuse having dual metal elastic clamps, comprising: an insulating cylindrical tube (101); a first metal cap (102A), wherein one end of the first metal cap is axially fixed on one end of a through hole; the other end of the first metal cap is connected with a first conducting wire extending outward; a second metal tube (102B), wherein one end of the second metal tube is axially fixed on the other end of the through hole; the other end of the second metal tube is connected with a second conducting wire extending outward. The first metal cap (102A), the second metal tube (102B) and the inner side wall of the middle part of the through hole form a temperature sensing chamber. The temperature sensing chamber axially arranges a plurality of components in the following sequence: a compressed spring; an insulating supporting pillar (402); a second metal elastic clamp (302); a connecting pillar (303); a first metal elastic clamp (301); an organic temperature sensing body (201) capable of melting when heating. The first metal elastic clamp, the second metal elastic clamp and the connecting pillar forms a movable conductive bridge. The movable conductive bridge slides flexibly in the temperature sensing chamber and has low contacting resistance with the first metal cap and the second metal tube. The above structure can withstand large current and has high realiability.

摘要： Disclosed is an apparatus comprising a thermal fuse and a resistor. The solid ceramic substrate of a wire wound resistor is changed to hollow, forming a ceramic tube (1). A thermal fuse is built-in the ceramic tube (1), the ceramic tube (1) becoming the housing of the thermal fuse. A lead wire (2b) of the thermal fuse passes through an end cover (5b) of the wire wound resistor at one end, connecting tightly thereto and forming a serial connection structure. A lead wire (2a) on the other end of the thermal fuse passes through the end cover (5a) of the wire wound resistor at the opening of the other end and extends outwardly. Also extending outwardly from the end cover (5a) of the wire wound resistor having an opening is a lead wire (8). The entire product is then encapsulated in epoxy resin (9). The apparatus can be used as a basic unit and directly installed in a existing high-frequency charger, replacing the existing simple wire wound resistor or wire wound resistor protected by an external thermal fuse, achieving the triple function of general impedance, over-current fuse protection, and over-temperature protection function in case of overload.
