  • Patent number: 8905795
    Abstract: Spring-loaded contacts having an improved reliability. One example may provide spring-loaded contacts having a reduced likelihood of entanglement between a spring and a plunger. For example, a piston may be placed between a plunger and a spring. The piston may have a head portion that is wider than the diameter of the spring and located between the spring and the plunger to isolate the spring and the plunger. In these and other examples, an additional object, such as a sphere, may be placed between the plunger and spring. In another example, two additional objects, such as two spheres, may be placed between a plunger and piston.

  • Patent number: 8888500
    Abstract: Connector inserts and receptacles that are robust, easily manufactured, and provide an improved connector performance. One example may provide a connector receptacle having a power contact located in a ground surface. An insulating layer may be placed between the power contact and the ground surface. The ground surface may be curved or flat, or it may have other shapes. Another example may provide a robust connector insert. This connector insert may include a crimping piece that fits over a cable braiding and is crimped. The crimping piece may then be attached to an attraction plate. A cover or shell may be attached to provide further reinforcement. Another example may provide a connector system having a ground contact and a power contact, where the ground contact is a make-first-break-last contact.

  • Publication number: 20140322988
    Abstract: A configurable and modular probe device for electrical connections. The probe device has multiple blocks capable of inter-fitting into various layouts. Each block has four sidewalls. Two adjacent sidewalls have a protrusion and the respective opposite sidewalls have a cavity corresponding to the protrusion. The protrusion of one block can removably mate with the cavity of a neighboring block. Each block further has a central cavity extending from a top surface to a bottom surface of the block. A probe snugly fits into the central cavity.

  • Patent number: 8857883
    Abstract: A vehicle includes a vehicle body that supports an electrical line that is electrically connected to a power source and that terminates at a first terminal. The vehicle also includes a window member with an electrical device supported thereon. A second terminal of the electrical device is supported on the window assembly, and the window member is moveable relative to the vehicle body. The vehicle further includes a passive electrical connector with a plunger that moves between a retracted position and an extended position. The passive electrical connector also includes a biasing member that biases the plunger toward the extended position. The passive electrical connector electrically connects the first and second terminals when the window member is in a first position. The plunger is biased toward the extended position when the window member is in the second position to electrically disconnect the first and second terminals.
