Method and Apparatus for Detecting Device Intrusion To A Network Interface Terminal

摘要

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.

主权项

1. A network coupling device, comprising:
an intrusion shrapnel having a cylindrical body with an opening through center of the cylindrical body, a first end of the cylindrical body attached to a first disc and a second end of the cylindrical body attached to a second disc; an elastic element situated between the first disc and a frame allowing the intrusion shrapnel to move within a limited distance; an intrusion plate electrically coupled to a printed circuit board (“PCB”) and situated adjacent to the second disc; and a bolt having a helical ridge thread able to pass through the open of the cylindrical body, wherein the intrusion plate and the second disc are capable of being electrically connected in response to movement of the bolt.
