Publication number: 20140130329Abstract: The present application relates to connectors that uses canted coil springs to retain a pin to a housing. The connectors have increased disconnect to connect force ratios. Dual concentric spring configuration allows for an initial locking configuration that can be overcome with higher force and deflection of the second spring. Dual springs in series in a constrained groove can require a high force for connector disconnect, since force vectors may be in a direction relatively close to being along the spring major axis. A curved groove wall can offer resistance to a spring that is required to slide first into the groove in order to allow disconnect.Type: ApplicationFiled: November 14, 2013Publication date: May 15, 2014Applicant: BAL SEAL ENGINEERING, INC.Inventors: Derek Changsrivong, Rick Dawson, Jim Sittler
