PCB mounted cover activated intrusion detection switch
View Patent ↗An intrusion detection switch is attached directly to a printed circuit board and utilized within an enclosure. Wires are not used to extend the switch to the top of the enclosure. An extension mechanism is used to extend a triggering portion of the intrusion detection switch to an engaging surface at the top of the enclosure. When the enclosure lid is properly shut, the engaging service is directed downward, thereby pushing an activation switch of the intrusion detection switch down. Switches may be assembled to an internal main printed circuit board where the switch is completely protected. Therefore, routing and maintaining of wiring to a switch is eliminated. A linkage system or mechanism can be mounted to the main chassis of the enclosure and act as an interface to an enclosure top cover. This eliminates potential damage to switches and wires and provides for a more reliable switch.
1. An intrusion detection mechanism, comprising:
an enclosure having a bottom, front panel, back panel, and two side panels;
a printed circuit board having circuitry for managing data;
an intrusion detection mechanism attached to the printed circuit board, wherein the intrusion mechanism includes the following positions:
a first position indicating that the front, back, and two side panels is installed,
a second position indicating that the front, back, and two side panels is partially installed, and
a third position indicating that the front, back, and two side panels is not installed;
an extension member extending from the intrusion detection mechanism to above a top surface of at least one of the panels, the extension mechanism forced downward towards the intrusion detection mechanism when a lid is placed over the top of the enclosure.
2. The intrusion detection mechanism of claim 1 , wherein the intrusion detection mechanism includes a spring activated lever that closes an open circuit when the extension member is forced downward.
3. The intrusion detection mechanism of claim 1 , wherein the intrusion detection mechanism has an open circuit when the extension member is at rest when extending above the top of the enclosure.
4. The intrusion detection mechanism of claim 1 , further comprising a power control unit providing power to the printed circuit board and the intrusion detection mechanism, wherein the intrusion detection mechanism triggers a signal to be sent to the printed circuit board when the circuit is open.
5. The intrusion detection mechanism of claim 1 , wherein the extension mechanism is guided by one or more rails.
6. A server enclosure, comprising:
a printed circuit board disposed within the server;
circuitry communicatively coupled to the printed circuit board; and
an intrusion detection switch attached to the printed circuit board, the intrusion detection switch transmitting a signal to the circuitry via the printed circuit board upon detecting a plurality of positions a lid for the server enclosure, wherein the intrusion detection switch includes the following positions:
a first position indicating that the lid is installed,
a second position indicating that the lid is partially installed, and
a third position indicating that the lid is not installed.
7. The server enclosure of claim 6 , further comprising a second intrusion detection switch attached to the printed circuit board and a second extension member extending from the intrusion detection mechanism to above top surface of an enclosure panel, the second intrusion detection switch transmitting a signal to the circuitry upon detecting that the lid for the server enclosure is disposed at a different location within the server enclosure.
8. The server enclosure of claim 6 , wherein the intrusion detection switch includes a spring.
9. The server enclosure of claim 6 , wherein the intrusion detection switch includes an optical sensor.
