Assignee:

Raychem Corporation - Menlo Park CA

International Classification:

H01C 1016

US Classification:

338220

Abstract:

An electrical assembly in which electrical connection is made to a device having two laminar electrodes and a laminar element between the electrodes, preferably a circuit protection device in which a PTC conductive polymer element is sandwiched between two metal foil electrodes. Connection is made to at least one of the electrodes by a resiliently deformed clip having an active arm which contacts one of the electrodes, and a passive arm which is not in conductive contact with the other electrode. Preferably there is an auxiliary member between the active and passive arms of the clip. The auxiliary member can be an insulator, or a conductive member which is spaced apart from the other electrode but secured to the same face of the PTC element as the other electrode.

Abstract:

A modular loudspeaker system of uniformly sized and shaped loudspeaker modules permits hanging of a plurality of the modules in a wide variety of desired configurations. Each module has a pair of side walls with recessed upper and lower marginal edge portions and an integrally formed reinforced connectable structure that spans between the recessed edge portions for reinforcement of the module across its side. When several modules are hung vertically, the vertically aligned reinforced connectable structures reinforce the system along its entire length. Three module types are disclosed, with one type adapted for removable mounting therein of a speaker horn via a quick release hub. Overall, the system provides optimum versatility in adapting to the acoustical requirements of a wide variety of performance venues.
