ABSTRACT:
A terminating device for terminating subscriber wiring to pairs of insulation displacement type conductive contacts includes a protective sealing gel disposed within the terminating device. The gel encapsulates the conductive contacts and is characterized by a dynamic storage modulus G′ and a dynamic loss modulus G″ expressed in dynes/cm2having a dynamic crossover point between about 1 rad/sec and about 20 rad/sec at any temperature in the range between about −40° C. to about 80° C. The loss modulus G″ is greater than the storage modulus G′ at a shear frequency greater than the dynamic crossover point and is less than the storage modulus G′ at a shear frequency less than the dynamic crossover point. The gel has an ultimate elongation greater than about 1000%, an ultimate tensile strength greater than about 2 psi, and a cone penetration value expressed in tenths of a millimeter between about 255 and 265.
