Magnetic electrical contact sensor
| DWPI Title: Magnetic electrical latch assembly for use in magnetic electrical contact sensor system of alarm system, has magnetic electrical contact arranged to couple with opposing contact pad to create electrical connection between contact pad and electrical contact |
| Abstract: A magnetic electrical latch assembly for sensing an electrical contact has a housing for supporting a magnetic electrical contact. The housing has an annular cavity and a cylinder disposed within the cavity. A magnetic electrical contact is attached at one end to the cylinder. The cylinder is movable axially within the cavity. The magnetic electrical contact has an electrical connection to a first conductive wire. The magnetic electrical contact is arranged to couple with an opposing contact pad to create an electrical connection between an external conductor path and the first conductive wire. Also, a magnetic electrical contact sensor system has a hollow enclosure with a detachable access panel. A meandering conductor path cover a portion of the access panel. The conductor path terminates on a contact pad. A magnetic electrical latch assembly has a housing for supporting the magnetic electrical contact within the enclosure. |
| Use: Magnetic electrical latch assembly for use in a magnetic electrical contact sensor system of an alarm system (all claimed). |
| Advantage: The assembly can simply open a monitored enclosure without damaging a circuit or disconnecting a complex mechanism before accessing contents by a service technician. The assembly can provide protection of many different irregular geometries with a single circuit device and magnetic connection. The assembly is simple and inexpensive to implement with the commonly available magnetic components. |
| Novelty: The assembly (30) has a housing for supporting a magnetic electrical contact (18) and formed with an annular cavity (46) fixed with a cylinder (42), where the magnetic electrical contact is attached to an end of the cylinder. The cylinder is axially movable within the cavity. The magnetic electrical contact is connected to a conductive wire (22) and coupled with an opposing contact pad (16) to create an electrical connection between the opposing contact pad and the magnetic electrical contact. The cylinder is freely and slidably movable within the annular cavity. The housing comprises a bolt assembly comprising a first threaded fastener and a second threaded fastener. |
