  • Publication number: 20160157393
    Abstract: An electrically conductive gasket for use with an electrical component, including an electrically conductive base defining a central opening therein for receiving a portion of an electrical component, a first row of spaced apart resilient conductive tabs arranged around the central opening, and a second row of spaced apart resilient conductive tabs arranged around the central opening, the first row being located inside the second row. The conductive tabs in the first and second rows of the spaced apart resilient conductive tabs extend outwardly from the conductive base and are configured to resiliently deflect when the gasket is compressed. The conductive tabs in the first and second rows of the spaced apart resilient conductive tabs are staggered relative to each other, such that in an edge view of the gasket, at least one conductive tab in one row partially overlaps at least one conductive tab in the other row.

  • Publication number: 20140302694
    Abstract: An electrical cable connector includes a cable connector housing and a latch attached to the cable connector housing. The cable connector housing includes a first set of electrical contacts and a latch channel. The latch includes an arm portion, a hinge portion, and an actuation portion. The arm portion is disposed in the latch channel and includes a pair of latch arms. The latch arms include opposing catch portions disposed at a front end thereof and are adapted to securely attach the cable connector to a mating connector by surrounding a protrusion inside a housing of the mating connector. The hinge portion extends from a back end of the arm portion. The actuation portion extends generally upwardly from the hinge portion. Pressing down the actuation portion about the hinge portion splays the latch arms such that the catch portions are moved away from each other.
