Bus Bars Patents (Class 174/72B)
  • Patent number: 6111745
    Abstract: The interface conductors, stabs and runbacks, which are engaged at first ends by quick disconnects on electrical apparatus in a switchgear assembly, are fabricated from a stacked pair of elongated, flat conductors secured together at the first ends by elongated fasteners which are compressed into countersunk through apertures in the flat conductors to form a joint with no lateral projections. The interface conductors are supported adjacent the disconnects by a first support having a base member with through openings in which the conductors are snugly supported, and rigid projections with planar surfaces extending from the base member toward the quick disconnects alongside the openings and against which the interface conductors are secured adjacent free ends of the projections. A second support spaced rearward of the first support provides additional support for the runbacks. Interphase supports formed by C-channels are provided for the runbacks between the first and second supports.

  • Patent number: 6100473
    Abstract: A support for busbars of a busbar system, which can be fixed in place on a fastening surface and which forms a receptacle which is adapted to a width and a thickness of the busbar. A later attachment to the pre-positioned busbar system is made possible due to correspondingly divided supports, if the support has two L-shaped receiving elements, whose legs, aligned parallel with the fastening surface, determine the width of the receptacle, and which have on front ends facing each other dovetailed strips and dovetailed grooves aligned with each other, which extend in a longitudinal direction of the busbar to be inserted into the receptacle. The legs of the receiving elements are oriented perpendicularly with respect to the fastening surface and determine the height of the receptacle. The facing sides of the two receiving elements have projecting support strips, which can be inserted into longitudinal grooves of the busbar, to be placed into the receptacle.

  • Patent number: 6024589
    Abstract: The present invention provides a reliable high current connector for connecting the ground and power planes of a first PCB to the ground and power planes of a second PCB. The power bus bar is comprised of a first conductive structure having a first and second surface, a second conductive structure having a first and second, and an inner insulative structure positioned between the first surface of the first conductive structure and the first surface of the second conductive structure. A fastening means, inserted through openings in the conductive structures, provides a secure, low resistance electrical connection from the first or second conductive structure of the bus bar to the electrical traces of the PCB. The high dielectric constant of the insulator provides distributed capacitance between the first conductive structure and the second conductive structure, lowering the AC impedance.

  • Patent number: 5979037
    Abstract: A mounting assembly and method for locating and assembling parts with a tight press fit uses an intentional design interference between two mating parts. Because of the interference fit, material is "crushed" or compressed when one mating part, such as a button frame, is forced upon the other mating part, such as a cabinet, and a tight fit is created. The interference fit is provided between first and second bosses and first and second mating holes, respectively, on opposite sides of each of the first and second bosses along a respective first axis, but not along a second axis that extends between the first and second bosses. Thus, a greater design tolerance is permitted in a direction between the first and second bosses and between the first and second mating holes, respectively. A third assembly part, such as a light guide, can be sandwiched between the first and second mating parts.

The high capacitance dielectric sheet is comprised of a monolayer of multilayer or single layer high dielectric (e.g. ceramic) chips or pellets of relatively small area and thickness which are arranged in a planar array. These high dielectric constant chips are spaced apart by a small distance. The spaces between the chips are then filled with a flexible polymer/adhesive to define a cohesive sheet with the polymer binding the array of high dielectric (e.g. ceramic) chips together. Next, the opposite planar surfaces of the array (including the polymer) are electroless plated or electroded by vacuum metal deposition, or sputtering, to define opposed metallized surfaces. The whole structure is then sandwiched between two conductive layers. The result is a bus bar with a very low characteristic impedance.

  • Patent number: 4867696
    Abstract: A backplane connector assembly including a motherboard connector and power and signal daughterboard connectors is disclosed. The motherboard connector has a signal section and a power section. Individual signal contacts are located in the signal section of the motherboard connector. A laminated power bus is located in the power section of the motherboard connector which is on the opposite side of the daughterboard from the signal section. Each of a plurality of separate busses in the laminated power bus has tabs extending from one edge and bent at right angles relative to the bus so that the tabs extend orthogonally relative to the daughterboard. This configuration permits daughterboards having different thicknesses to be mated inserted into the same motherboard connector. The laminated power bus permits power to be delivered externally of the motherboard to the daughterboards.

  • Patent number: 4728752
    Abstract: A reducing joint assembly which, when attached at one end thereof to a bus duct having a predetermined number of runs and at the other end thereof to a bus duct having a different number of runs, allows interconnection of these non-matching ducts without undue wasted length or materials. The reducing joint assembly includes one conventional single bolt coupler at each end thereof for each run to be connected at that respective end of the assembly. Connected between the respective single bolt couplers is a single reducer plate for each phase of the bus duct system. Each such reducer plate has tabs at each end, one for each single bolt coupler, so that the reducer plates in effect interconnect with the single bolt coupler in generally the same manner as do the bus plates of each bus duct. The apparatus also includes specialized joint covers for covering the joint thus created to prevent the entry of foreign objects.

  • Patent number: 4694123
    Abstract: A backplane power distribution system characterized by generally uniform current densities so as to be capable of handling very high levels of current. This is achieved with a stepped backplane construction. For example, in a system having, in order, a first conductive layer, a first dielectric layer, a second conductive layer, and a second dielectric layer, the second conductive and dielectric layers extend transversely beyond the first conductive and dielectric layers to present a substantial exposed area of the second conductive layer. Typically, a rectangular metal bus bar is bolted to the backplane to make contact with the exposed area, and power supply connections to the bus bar are made in any convenient manner.
