DEFINITION

Classification: 337/291

(under subclass 290) Subject matter including at least one element of appreciable tensile strength parallelly connected to a fusible element of comparative weak tensile strength. The strain relief member is utilized to protect the fusible element against tensile stresses which tend to rupture it under normal conditions of usage. The strain element is usually of conducting material capable of carrying a certain amount of current both before and after the fusible element has been ruptured.
