Abstract
This invention is a secure and long-lasting ground connection, or isolation terminal, for, for example, fiber optic cable installations. The isolation terminal has a proximal end with a hole in a conductive element for receiving a stud extending out from the terminal box, and a nut placed on the stud, or for receiving a bolt placed in the hole for being received by the terminal box. Surrounding and enclosing the conductive element with the hole is a walled structure which is adapted on its lower end to fit and cooperate with the external wall of the terminal box, helping to create a tight seal between the terminal box and the isolation terminal. The inside of the walled structure creates a cavity which is closeable by means of a close-fitting cap, for example. After tightly attaching the isolation terminal to the terminal, the cavity is filled with an insulator, like a dielectric gel, for example, and then the cap is closed to securely cover the cavity. This way, the electrical ground connection is protected against infiltration by the environment and resulting corrosion or decay.
