Sterilization effects on soldered and welded joints, electronic equipment processes and materials, electric connectors, and wiring and cabling accessories
Humidity, temperature, contamination and disconnection effects on gasket and grease seals for extended space mission computer connectors
Harsh Environment Protective Housings for Electrical and Fluid Connectors.
This presentation describes results of Techno-Economic Analysis: to quanitfy Impacts of PV Module Connector Failures on Cost and Performance of Utility Scale Photovoltaic Systems, with example of 100 MW Utility Scale PV System. Results indicate impact on Levelized Cost of Energy on the order of $1.22/MWh in the example.
This poster presents an overview of a study of the impact on PV system cost and performance imposed by electrical connectors used to connect PV system components.
This presentation is to guide interactive discussion by posing questions to workshop participants. Topic is reliability, maintenance cost, and performance risk associated with failure of PV connectors which make electrial connections between components.
The National Laboratory of the Rockies (NLR) has a long history of studying the outdoor reliability of electrical connectivity components, including connectors, cables, wire harnesses, and fuses.
5 min panel presentation for the EPRI connector workshop.
QC4.10 connectors are cracking within months after installation. The issue affects at least three sites across two developers, but the root cause unknown.
Design criteria for zero-leakage connectors for launch vehicles - plastic flow & flange rolling
A standard radio frequency coaxial connector is modified so that a plastic insulating sleeve can be mounted in the wall of a vacuum chamber. This eliminates ground loops and interference from cable connections.
Soldering and welding techniques are used to connect a coaxial cable to a printed circuit board. This device aids reliability control of equipment as standard connectors are bulky and heavy.
A connector that will serve as a seal for fluids at cryogenic temperatures and in high vacuums was constructed by installing a metal disk between two sets of mating serrations to form two sealing surfaces. Compression on both sealing surfaces is ensured by spring action of the disk.
Feed-through connector with sealing action augmented by any temperature increase can be used through the wall of a vacuum device. It retains vacuum integrity through successive cycles of high temperature.
Extremely fine finished surfaces as mating parts for sealing in fluid connectors and statistical analysis of interface leakage
Portable, compact tool quickly and cleanly removes brazed connectors from system tubes. The tool uses an induction coil to melt the braze and a compression spring to automatically separate the connection. An inert gas is force-fed about the heated area to prevent oxidation of the tube.
Bismuth alloy potting seals feedthrough electrical connector for instrumentation within a pressurized vessel filled with cryogenic liquids. The seal combines the transformation of high-bismuth content alloys with the thermal contraction of an external aluminum tube.
Hinge makes both sides of electrical circuit boards readily accessible for component checkout and servicing. The hinge permits mounting of two circuit boards and incorporates connectors to maintain continuous electrical contact between the components on both boards.
