Abstract
A current-limiting protector package for use in conjunction with telephone terminal blocks comprises a two-piece interfitting housing which is made up of two housing halves soncially welded together. A pair of tip or ring terminals is disposed within each housing half along with a current-limiting device in the form of a positive-temperature-coefficient (PTC) device of the conductive polymer type. Lower end portions of the tip or ring terminals project outwardly from the housing so as to be capable of electrical engagement with opposed sets of terminals provided upon the telephone terminal block, while upper end portions of the tip or ring terminals project outwardly from the housing so as to be accessible to a line test probe whereby the lines or circuits of the telephone terminal block can be tested in connection with their operative status without necessitating removal of the protector package from the terminal block.
