  • Patent number: 10256561
    Abstract: A terminal with ribbed contact springs for receipt of a mating terminal therein. The receptacle terminal has a contact portion which includes a bottom wall with contact sections extending from opposed sides of the bottom wall. Each of the contact sections have at least two resilient arms which extend from the bottom wall to a mating terminal engagement member. The at least two resilient arms have arcuate portions which extend from the bottom wall to the mating terminal engaging members. Each of the at least two resilient arms has a reduced contact spring rate, thereby allowing the contact normal force to be more accurately controlled with the same manufacturing tolerances. More controlled normal force allows for a minimum contact normal force to be reliably maintained while reducing the insertion force required during mating.

  • Patent number: 10193259
    Abstract: A receptacle connector includes a housing and a terminal held within a cavity of the housing. The housing includes a top wall, a bottom wall, and first and second side walls. The housing includes a first hold-down rib in a first corner region of the cavity defined by the top wall and the first side wall, and a second hold-down rib in a second corner region of the cavity defined by the top wall and the second side wall. The terminal defines a receptacle configured to receive a mating tab contact therein through a mating end of the housing. The first hold-down rib engages an outer surface of a first rolled wall of the terminal and the second hold-down rib engages an outer surface of a second rolled wall of the terminal to limit float of the terminal within the cavity.

  • Patent number: 10103469
    Abstract: A receptacle terminal for receipt of a mating terminal therein. The receptacle terminal includes a contact portion having a bottom wall and resilient arms which extend from either side of the bottom wall. The bottom wall has a raised portion with a first embossment position proximate a lead-in surface at a mating end of the contact portion. The bottom wall has a second embossment spaced from the first embossment, the first and second embossments providing additional strength and stability to the contact portion to prevent unwanted bending of the terminal. This provides a stable electrical connection while allowing for a lower insertion force of the mating terminal into the socket terminal.

  • Publication number: 20180159813
    Abstract: A method is provided in one example embodiment and includes detecting by a first network element at a first data center site a local connection of an endpoint identifier (“EID”), in which the EID was previously locally connected to a second network element at a second data center site and notifying a mapping server of the local connection of the EID to the first network element. The method further includes receiving from the mapping server identifying information for the second network element and communicating with the second network element using the identifying information to obtain service information for traffic associated with the EID. The method may also include applying a service identified by the service information to outgoing traffic from the EID as well as applying a service identified by the service information to incoming traffic for the EID.

  • Patent number: 9919381
    Abstract: A method for cutting a flexible glass ribbon includes directing the flexible glass ribbon to a flexible glass cutting apparatus including a laser. The flexible glass ribbon includes a first broad surface and a second broad surface that extend between a first edge and a second edge of the flexible glass ribbon. A laser beam is directed from the laser onto a region of the flexible glass ribbon. A crack is formed through the flexible glass ribbon using the laser beam. The crack is propagated along the flexible glass ribbon using the laser beam and a local mechanical deformation in the flexible glass ribbon.

  • Publication number: 20150321948
    Abstract: A process and system for applying coating materials to glass edges of various profiles. The glass edge is coated by picking up the coating material from an applicator such as, for example, a roller, through precise independent or relative control of the spatial relationship between the edge of the glass article and the applicator to achieve desirable product attributes such as coating thickness, profile, coverage areas and consistency. Such spatial relationships include the gap distance between the roller and applicator, coating thickness on the applicator, applicator and/or glass speed, and the like.
