Patent number: 9190773Abstract: Axially compressible F-connectors for conventional installation tools for interconnection with coaxial cable include radially compressed grounding inserts seated within a body fitted to a nut socket. Each connector has a rigid nut, a post penetrating the nut, a tubular, metallic body, and an end cap. The conductive post coaxially extends through the connectors, linking the nut and body. A post end penetrates the coaxial cable. The nut has an integral, tubular socket at its rear that is engaged by a tubular, metallic connector body. The body front has at least one groove for receiving a peripheral grounding insert, preferably in the form of a coiled spring wrapped around the body, that is radially sandwiched within the nut socket to insure grounding. An end cap press fitted to the assembly coaxially engaging the body, closing the fitting. Internal O-rings may be combined for sealing the connector.Type: GrantFiled: August 20, 2012Date of Patent: November 17, 2015Assignee: PerfectVision Manufacturing, Inc.Inventor: Glen David Shaw

Patent number: 9182424Abstract: A chip testing solution having two separate contacts: one to provide current and one to measure voltage. One contact acts as the force and other as sense, and with its unique short wipe stroke technology enables the electrical connection from the contact terminal of the device under test (DUT) to the loadboard without fail even after prolonged insertion/testing of the devices. The two contacts are in close proximity, but electrically isolated from each other. Each contact is made to electrically touch a single conductive lead/pad on the DUT thus forming a test connection. The two contacts; one on front and other on back, wiping on the lead/pads will generally be a “sense” probe, and a “force” used for making a Kelvin connection. The short contact is connected to the loadboard by means of an additional contact known as “interposer” extending through and top of the tall contact base body.Type: GrantFiled: March 19, 2013Date of Patent: November 10, 2015Assignee: JF MICROTECHNOLOGY SDN.
