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...
