Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0023] A winding method of a high-precision resistor of the present invention comprises the following steps:

[0024] 1) Enamelled manganin wire (2) is wound around the middle part of the skeleton (1); both ends of the skeleton (1) are metal welding posts, and the middle part is non-metallic. Such as figure 2 shown.

[0025] 2) Weld the initial end of the enamelled manganese-copper wire (2) on the through hole of the welding post of the skeleton (1), and temporarily fix the other end with high-temperature adhesive tape; figure 1 shown.

[0026] 3) Bake the assembly formed in step 2) in an oven at 180°C for 24 hours to eliminate the winding stress;

[0027] 4) After the components baked in step 3) are naturally cooled, measure the resistance at both ends of the enamelled manganese-copper wire (2), if th...

Abstract

The invention relates to a method for winding a high-precise resistor. The method comprises the following steps: winding an enameled manganese copper wire (2) in the middle of a frame (1); welding theinitial end of the enameled manganese copper wire (2) on the through hole in one welding stud of the frame (1); roasting components; measuring whether the resistance value of the enameled manganese copper wire (2) reaches the standard or not; welding the tail end of the enameled manganese copper wire (2) on the through hole in the other welding stud of the frame (1); coating an insulating paint layer on the enameled manganese copper wire (2); and uniformly coating the periphery with 703 glue. The method for winding a high-precise resistor is designed according to the special circuit structureof aircraft control products, the resistor precision meets the circuit requirement, the resistance value of the resistor cannot drift in high and low temperature environments, and the effect is excellent.

Description

technical field [0001] The invention belongs to the technical field of component assembly, and in particular relates to a winding method of high-precision resistors. Background technique [0002] Standard general-purpose resistors on the market are mainly connected to electrical products through through-hole mounting or surface mount, while aviation control electrical products have a special structure, which requires high precision of the circuit, and standard general-purpose resistors cannot be installed and used. Contents of the invention [0003] The purpose of the present invention is to solve the problem that standard universal resistors cannot be used in the circuit due to the use of space structures in aviation control products. The present invention proposes a winding method of high-precision resistors to meet the installation requirements of resistors with special structures. [0004] Considering the above-mentioned problems of the prior art, according to one aspe...
