Abstract
In junction boxes for coupling T.V. signals and low frequency power waves on a coax line to a plurality of users, the T.V. signals are coupled via connections in a first compartment to a plurality of coax cables, and the low frequency power wave are coupled via low pass-filters to IDC connections in a second compartment. Leads from users are passed through a chamber on the wall of the second compartment containing a self-healing, self-supporting insulating substance and attached to the IDC connectors. The IDC connectors permit the lead to be paired through them so that an installer can know when the leads are properly partitioned.
