The invention relates a method for fixing of a power supply cord within the plastic box of cooking appliance by the application of the strain-relief with poka-yoke solution and indication on plastic protection box.
More specific, the solution is based on the main cord guidance through the specific configuration of certain number of bosses and ribs, in proximity of wire connection relief, with the scope to arrange a certain number and forms of cord’s successive curvatures fit the ribs and bosses configuration, enabling a sufficient level of friction force on the cord to fix it..
Accordingly, the invention provides a method to fix the main cord on the appliance without strain-relief clamp application, excluding by this the specific time and costs for its assembling and quality control testing. Moreover, the method enables the main cord fixing without tightening and possible mechanical damaging of the same.
