Abstract:
In a polarized electrical component, a first electrode is provided at an inner-side bottom face of the component, and a second electrode is provided at an outer-side bottom face of the component. One of the first and second electrodes serves as an anode electrode, and the other serves as a cathode electrode.
Abstract:
Thin-profile battery circuits and constructions, and in particular button-type battery circuits and constructions and methods of forming the same are described. In one implementation, a substrate is provided having an outer surface with a pair of spaced electrical contact pads thereon. At least two thin-profile batteries are conductively bonded together in a stack having a lowermost battery and an uppermost battery. The batteries include respective positive and negative terminals. The lowermost battery has one of its positive or negative terminals adhesively bonded to one of the pair of electrical contact pads while the uppermost battery has one of its positive or negative terminals electrically connected to the other of the pair of electrical contact pads. The batteries can be provided into parallel or series electrical connections.
Abstract:
A varistor with no connecting legs extending from it, is mounted in a slot formed in a printed circuit board. The printed circuit board carries the normal circuit tracks. The physical and electrical connection between the printed circuit board and the varistor is achieved by the use of solder. When the varistor overheats to a temperature beyond a predetermined temperature, the solder melts and the varistor is separated from the printed circuit board. A leaf spring which is biased when the varistor is inserted into the slot pushes the varistor out of the slot when the solder melts. Alternatively, when the solder melts gravity causes the varistor to fall out of the printed circuit board.
Abstract:
In a surface mount assembly, an active integrated circuit device, such as, for example, a dynamic random access memory, typically has a lead finger attached to a solder pad of a printed wiring board. The surface mount assembly is significantly improved by configuring a passive component, such as a resistor or capacitor, such that it has metallic terminations on an upper and lower surface so that it may be positioned between the solder pad of the printed wiring board and the lead finger.
Abstract:
An electrical circuit package comprise a stamped and formed lead frame to which is molded a dielectric housing member which includes openings having exposed electrical contacts, the housing member providing support for the lead frame. Some of the exposed contacts in the openings serve to support electrical components in the openings and to make electrical contact therewith while other of the exposed contacts in the openings electrically engage the electrical components and maintain them in the openings. Further exposed contacts electrically engage another electrical component and the housing member and the further exposed contacts maintain the other electrical component in the housing member. An electrical switch is part of the lead frame.
