Abstract

The invention belongs to the technical field of resistors, and particularly discloses a low-power aluminum alloy cement resistor. The low-power aluminum alloy cement resistor comprises a strip box cover, a strip bottom shell, wherein a first U-shaped groove and a second U-shaped groove are arranged at two ends of the strip box cover; strip buckles are symmetrically arranged at two sides of the strip box cover; a first clamping groove and a second clamping groove are arranged at two ends of the strip bottom shell; strip clamping plates are symmetrically arranged at two sides of the outside of the strip bottom shell; a ceramic shaft rod and a resistance wire are arranged in the strip bottom shell; and lead-out wires are arranged at two ends of the ceramic shaft rod. The low-power aluminum alloy cement resistor has the beneficial effects that (1) an aluminum alloy shell is relatively good in heat dissipation performance, and is filled with insulating and heat-conducting materials when produced, so that the service lifetime of the resistor is prolonged; (2) the low-power aluminum alloy cement resistor is simple to assemble and fit, and high in production efficiency; (3) the error is small and is within a range from +5% to -5%; and the control accuracy is high; and (4) an alloy resistance wire is low in noise, resistant to short-time overload, free of a change in resistance value and stable in performance. Meanwhile, the low-power aluminum alloy cement resistor is simple in structure, low in production cost and easy to popularize.

Description

technical field [0001] The invention relates to the technical field of resistors, in particular to a low-power aluminum alloy cement resistor. Background technique [0002] Cement resistor is a kind of wire-wound resistor, which has the characteristics of large size, shock resistance, moisture resistance, heat resistance, good heat dissipation, and low price. It is widely used in power adapters, audio equipment, audio frequency dividers, instruments, meters, TVs, cars and other equipment. However, the current cement resistors are usually high-power and have the following disadvantages: 1. High calorific value and poor stability during use; Standards for the use of equipment accessories; 3. The existing low-power cement resistors have large errors and low precision. [0003] Therefore, based on the above problems, the present invention provides a low-power aluminum alloy cement resistor. Contents of the invention [0004] Purpose of the invention: The purpose of the inve...
