  • Publication number: 20060063417
    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/cm2 having 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.

  • Patent number: 6299475
    Abstract: A distribution terminal block for connecting individual drop wires to incoming telephone cable wires has a base that receives attachable modules. Each module has a pair of IDC clips. A plunger adapted for reciprocal movement within the module along a plunger axis presses the drop wires into engagement with the IDC clips. The module has a cavity filled with an electrically insulating gel. The plunger has an upper portion and a lower portion separated by a recess for receiving the drop wires. A spine connects the upper portion and the lower portion of the plunger. The lower portion has a smaller cross-sectional area than the upper portion and has an angled, sharp end for reducing disturbance to the insulating gel during movement of the plunger to insert, remove and reinsert the drop wires.
