AI Technical Summary
Traditional stainless steel mica heating elements have complex and unreliable resistance wire installation structures, which cannot adapt to the slight deformation of the resistance wire under vibration or temperature changes, resulting in gaps, poor contact, or even open circuit failures at the interface.
The structure employs a rotating cover plate adjustment rod and pressure plate, combined with an elastic constraint system of compression spring and positioning hoop, to achieve rapid positioning and double fixation of the resistance wire. The pressure plate is pressed down by rotating the adjustment rod, and a stable connection is formed by utilizing the self-adaptive nature of the spring and the vertical pressure of the pressure plate.
It enables rapid installation and stable fixation of the resistance wire, preventing poor contact caused by vibration or thermal expansion and contraction, and improving the reliability and service life of the equipment.
