Abstract
An overvoltage protector assembly and a method of attaching a terminal member through a dielectric body. The assembly has a dielectric body, and line terminal members extending through the body into a chamber within. The terminal members each have a shaft passing through the body and first and second radially extending, opposing abutment surfaces which engage inner and outer surfaces of the body. The body is compressed between the opposing abutment surfaces in an axial direction of the shaft to deform the body inwards to sealingly engage the terminal member between the opposing abutment surfaces. The body is formed with axial projections around apertures receiving the line terminals, so that compressing the body results in displacement of material of the body to form annular projections sealingly engaging around the shaft between the abutment surfaces. Peripheral surfaces of the terminal member are cooperable with the body to prevent relative rotation of the body and the terminal member. The line terminal members are connected to a grounding terminal within the chamber via an overvoltage protection device.
