Abstract

The invention discloses a fusing resistor easy to assemble. The fusing resistor comprises a shell and two pins, a mounting base is clamped in the shell, an organic matter thermal fuse body is mountedin the mounting base, a connector is arranged above the mounting base, a columnar bulge is arranged at a bottom of the connector, two lower fan-shaped grooves are arranged in an upper surface of the connector, and lower electric conductors are clamped in the lower fan-shaped grooves; a cover body is arranged at a top of the shell, an upper fan-shaped groove is arranged in the middle of a lower portion of the cover body, a columnar through hole is arranged in an upper portion of the upper fan-shaped groove, two pins are arranged in the columnar through hole, and an upper electric conductor is arranged in the upper fan-shaped groove in a clamped mode; and the connector is connected with the cover body through a spring. Compared with the prior art, by using the resistor of the invention, there are the following advantages that the structure is reasonable, installation and connection are convenient, and safety is good; assembly efficiency and an assembly effect are improved; and after a temperature of electric equipment rises abnormally, a circuit is disconnected quickly, and the electric equipment can be continuously used by simply replacing part of elements so that cost performance and a use value are relatively good.

Description

technical field [0001] The invention belongs to the technical field of fuse resistors, and in particular relates to an easy-to-assemble fuse resistor. Background technique [0002] Fuse resistors are used to detect thermal abnormalities in industrial electrical equipment and household electrical equipment, and to cut off circuits. In fuse resistors, the resistance element and the thermal fuse element are electrically connected in series, and the heat of the resistance element is transferred to the temperature. Fuse element; the thermal fuse element includes an organic thermal fuse and an alloy fuse. Since the installation process of the alloy fuse is cumbersome, when the alloy fuse is heated and disconnected, it shrinks to both sides and becomes spherical. Therefore, the organic thermal fuse that is more convenient to install Fuses are more often used in fuse resistors, but the lead wires of existing fuse resistors are usually at both ends of the resistor, and an insulating ...
