  • Patent number: 9098729
    Abstract: A network interface terminal (“NIT”) able to provide network service includes an intrusion shrapnel, elastic element, intrusion plate, and bolt is disclosed. The intrusion shrapnel, in one embodiment, has a cylindrical body with an opening through center of the cylindrical body. First and second discs are attached to each end of the cylindrical body. The elastic element, such as a spring, is situated between the first disc and a frame applying a force pulling the intrusion shrapnel in a disengaging direction. The intrusion plate which is electrically coupled to a PCB is situated adjacent to the second disc. The bolt having a helical ridge thread passes through the open of the cylindrical body and makes the second disc to electrically contact with the intrusion plate.
