Title of Invention	A COMPOSITE CIRCUIT PROTECTION DEVICE
Abstract	A composite circuit protection device (10) includes first and second laminar circuit protection devices (11, 12), and an optional laminar insulating member (53). Each of the first and second laminar circuit protection devices includes (1) a first laminar electrode (13); (2) a second laminar electrode (15); (3) a laminar PTC resistive element (17) which (i) exhibits PTC behavior and (ii) has a first face to which the first electrode is secured and an opposite second face to which the second electrode is secured; (4) a third laminar conductive member (49) which (i) is secured to the second face of the PTC resistive element, and (ii) is spaced apart from the second electrode; (5) a fourth laminar conductive member (35) which (i) is secured to the first face of the PTC resistive element, and (ii) is spaced apart from the first electrode; (6) a first transverse conductive member (51) which runs between the first and second faces of the PTC element, is secured to the PTC element, and is physically and electrically connected to the first laminar electrode and to the third laminar conductive member, but is not connected to the second laminar electrode, and (7) a second transverse conductive member (31) which runs between the first and second faces of the PTC element, is secured to the PTC element, and is physically and electrically connected to the second laminar electrode and to the fourth laminar conductive member, but is not connected to the first laminar electrode. The first and second laminar devices are physically secured together in a stacked configuration, with the laminar insulating member between them, if present; and the devices are connected together electrically by interfacial electrical connections (54) between adjacent electrodes and laminar conductive members so that when an electtrical power supply is connected to (i) one of the electrodes and (ii) the third or fourth laminar member on the same face of the PTC resistive element as the electrode (i), the first and second laminar circuit protection devices are connected electrically in parallel.

Abstract

A composite circuit protection device (10) includes first and second laminar circuit protection devices (11, 12), and an optional laminar insulating member (53). Each of the first and second laminar circuit protection devices includes (1) a first laminar electrode (13); (2) a second laminar electrode (15); (3) a laminar PTC resistive element (17) which (i) exhibits PTC behavior and (ii) has a first face to which the first electrode is secured and an opposite second face to which the second electrode is secured; (4) a third laminar conductive member (49) which (i) is secured to the second face of the PTC resistive element, and (ii) is spaced apart from the second electrode; (5) a fourth laminar conductive member (35) which (i) is secured to the first face of the PTC resistive element, and (ii) is spaced apart from the first electrode; (6) a first transverse conductive member (51) which runs between the first and second faces of the PTC element, is secured to the PTC element, and is physically and electrically connected to the first laminar electrode and to the third laminar conductive member, but is not connected to the second laminar electrode, and (7) a second transverse conductive member (31) which runs between the first and second faces of the PTC element, is secured to the PTC element, and is physically and electrically connected to the second laminar electrode and to the fourth laminar conductive member, but is not connected to the first laminar electrode. The first and second laminar devices are physically secured together in a stacked configuration, with the laminar insulating member between them, if present; and the devices are connected together electrically by interfacial electrical connections (54) between adjacent electrodes and laminar conductive members so that when an electtrical power supply is connected to (i) one of the electrodes and (ii) the third or fourth laminar member on the same face of the PTC resistive element as the electrode (i), the first and second laminar circuit protection devices are connected electrically in parallel.
