摘要:
An electrical distribution system having specially formed and insulated bus bars (40) in back to back, stacked relationship with each other along the length of the busway and spaced apart where tap-off or other connection may be made (34). The bus bars are formed to be interchangeable, to the extent possible, within a busway section (32). For example, in a four bar plug-in section, the two inner bus bars are identically formed and interchangeable by rotating the bars 180o. Similarly, the two outer bus bars are also identically formed and interchangeable. The electrical insulation between bus bars is provided by the use of insulating tubes comprising one layer of varnished glass cloth between two layers of polyethylene therephthalate. Each bar (40) is provided with a hump (54) located for tap-off connection along the length of the busway. The insulating tubes are spaced apart from each other on each bus bar (40) to provide a tap-off contact surface (238) on each hump (54). Each tube is provided with notched out segments (236) which overlie the edge of the bus bar (40) at a transition portion of the hump (54). A hump insulator (240) is placed longitudinally along the length of the bus bar (40) on the top and bottom of the hump (54) between opposing plug-in bases and hump edge insulators (242) are placed on the edges of the plug-in bars in overlying relationship with the respective notched out segments (236) on the tubes.
摘要:
A method for manufacturing high capacitive multilayer conductive bars is described. It comprises at least two conductive elements (14, 16), one capacitive element (12) between them, and further innerand/orouter dielectric elements (13,113,18,20). The electrical connection between the capacitive element (12) and the conductive element (14, 16) is realized by a solder alloy material (30), preferably in the form of a soldering alloy material. The mechanical connection between the outer (18, 20) respectively the inner dielectric elements (13, 113) and the conductive elements (14, 16) is established by a non- conductive bonding material (13'.113', 22, 24). Mechanical as well as electrical connection is made in the same operation step. The multilayer conductive bar has a great reliability. It is used for power and/or signal distribution in electronics, for example printed circuits and other high density components.

摘要:
A high capacitance bus bar is presented having at least two separated conductive plates (12, 14) between which a plurality of capacitive ceramic dielectric chips (20) are positioned and adhered. The outer surfaces of the dielectric chips are metalized (22) and have a roughened or coarse finish to provide contact between the dielectric chips (20) and the conductive plates (12, 14), thereby permitting use of nonconductive adhesive (18) to bond the parts of the assembly together.
