Abstract: A wire connector which includes a metal thread insert and at least two unmixed components within the connector cavity which are mixable as the insert is screwed onto bared wire ends to form a cement for bonding the connection of the bared wire ends to each other and to the insert. The components are separated by a barrier layer formed by a reaction at their interface. At least a portion of the insert is disposed inwardly of the cavity relative to the barrier layer. The barrier layer is pierceable by the bared wired ends during insertion thereof into the insert for screwing of said insert onto the bared wire ends.
