More Information
Summary:The invention discloses an isolating device of a slot discharge machine tool. The isolating device comprises an insulating waterproof assembly and an insulating cover body. The insulating waterproof assembly is electrically insulated from a current circuit assembly and isolates the current circuit assembly from working fluid. The insulating cover body prevents the working fluid from entering into the insulating cover body because the internal air pressure of the insulating cover body is higher than the pressure of external liquid, so that the current circuit assembly including contacts in the insulating cover body is isolated from the working fluid. Therefore, the isolating device disclosed by the invention can effectively prevent the current circuit assembly from being corroded by the working fluid, leaking current and producing a bypass circuit effect.
