Abstract
This utility model discloses an encoder with an anti-interference structure, belonging to the field of encoders. The encoder body has a front cover at its outer end, with first side ears on both sides. The end faces of the first side ears have mounting holes. The front cover is connected to the encoder body by fastening bolts. An isolation shell is provided between the front cover and the encoder body, with second side ears on both sides. The first and second side ears are compatible for installation. The front cover protects and fixes the encoder body, preventing external physical damage and ensuring stable operation. The isolation shell contains aluminum foil, which is tightly connected to the front cover and the encoder body, forming an anti-interference isolation layer to block external electromagnetic interference. An isolation cover is fixedly connected to the isolation shell and contains an inner cavity and a copper wire braided shielding isolation layer, constituting a complete anti-interference system. This system enhances the shielding effect and also dissipates encoder operating heat through heat dissipation fins and heat-conducting pillars, ensuring stable operation in high-temperature environments.
