Abstract

The invention relates to a wire-wound resistor with an aluminum shell, which comprises the aluminum shell and a resistor framework, wherein two ends of the resistor framework are connected with resistor leading-out wires, and multiple layers of resistance wires are wound on the resistor framework to form a resistor body; isolation insulating discs are arranged between the multiple layers of resistance wires; insulation barriers are arranged on the upper surface and lower surface of the resistor body; the aluminum shell is groove type, and is fixedly arranged outside the insulation barriers in an up and down opposite manner; and the resistor framework is I-shaped, and the multiple layers of resistance wires are wound in the concave region of the I-shaped resistor framework. The wire-wound resistor with the aluminum shell provided by the scheme is stable in quality and performance, convenient for installation, and uniform in overall dimensions.

Description

technical field [0001] The invention relates to an electronic component, in particular to an aluminum casing wirewound resistor, which is especially suitable for frequency conversion, servo and electronic components for voltage reduction, current limiting, load, release and the like. Background technique [0002] Wire-wound resistors are a type of resistors made of resistance wire wound on an insulating frame and then insulated and packaged. The resistance wire is generally made of nickel-chromium, manganese-copper and other alloys with a certain resistivity. The insulating frame is generally made of ceramics, Plastic, metal skeleton coated with insulation. It has the characteristics of small temperature coefficient and high precision. Among the wire-wound resistors, there is a high-power wire-wound resistor that uses ceramics as the skeleton and coats the outer layer of the resistor with glaze or other heat-resistant and heat-dissipating insulating materials. [0003] At ...
