Abstract:
A midplane connector system (100) comprises a midplane circuit board (110) having a first header assembly (116) and a second header assembly (118) mounted to respective opposite sides of the midplane circuit board. A first receptacle assembly (132) is coupled to the first header assembly and coupled to a first circuit board (130). A second receptacle assembly (152) is coupled to the second header assembly and coupled to a second circuit board (150) which is orthogonal to the first circuit board. The first receptacle assembly has signal contacts with mating portions arranged in pairs that are oriented parallel to the first circuit board, and the second receptacle assembly has signal contacts with mating portions arranged in pairs that are oriented perpendicular to the second circuit board.
Abstract:
An assembler receives a circuit board. The circuit board includes at least a first node and a second node that are adjacent but electrically isolated from each other. There is a gap between the first node and the second node. The first node is electrically isolated from other components on the circuit board. The second node is electrically coupled to circuitry residing on the circuit board. The assembler initiates positioning of a conductive lead of a battery in a vicinity of the first node. The gap between the first node and second node initially prevents the live conductive lead from being in electrical contact with the second node. Eventually, the assembler bridges the gap to provide an electrical connection between at least the conductive lead and the second node to electrically couple the conductive lead to the second node and thus the circuitry residing on the circuit board.

The invention relates to a battery cell interconnector and voltage sensing assembly and a method for connecting a battery cell assembly. The battery cell interconnector and voltage sensing assembly includes a circuit board, electrical interconnecting members, and an electrical connector. The circuit board further includes slots for accommodating the electrical interconnecting members. Electrical terminals from a battery cell assembly are connected to the electrical interconnecting members. The circuit board further includes electrical traces for inducing voltages at the electrical interconnecting members to the electrical connector to sense voltages of the battery cell assembly.
Abstract:
A solder-bearing lead (10) for attachment to the surface of a substrate (39), wherein a discrete mass of solder (24) is mechanically held firmly by the lead (10) in a position permitting close proximity to the substrate surface to connect the lead (10) to the substrate (39) with an electrical and mechanical bond upon melting of the solder (24), the lead body having a pair of fingers (22) partially encircling the solder mass (24) with a gap (32) between the fingers (22) providing an unobstructed flow for the melted solder to the substrate. The lead may also be used to interconnect a first substrate (39) to a second substrate (44), forming a bond between conductive areas (45, 46) on both substrates.
Abstract:
Printed circuit boards (PCBs) are configured with an athermalized mounting suitable for securing and positioning and the PCBs within an inertial measurement unit (IMU). The PCBs include integrated circuit (IC) components, such as accelerometers and/or gyroscopes, which require relative positional stability within the IMU environment in order to provide accurate results. The athermalized mounting configuration of the PCB enables the PCBs to experience thermal expansion within the IMU without causing significant displacement of the IC relative to the IMU environment.
