  • Patent number: 9065230
    Abstract: A cable connector with improved performance and ease of use. The connector has staggered ports to reduce crosstalk and to prevent incorrect insertion of a plug into a receptacle. The plug may be constructed with subassemblies, each of which has a lossy central portion. Conductive members embedded within an insulative housing of the subassemblies may be used to electrically connect ground conductors within the subassemblies. Further, the connector may have a quick connect locking screw that can be engaged by pressing on the screw, but requires rotation of the screw to remove. Additionally, a ferrule may be used in making a mechanical connection between a cable bundle and a plug and making an electrical connection between a braid of the cable bundle and a conductive shell of the plug. The ferrule may be in multiple pieces for easy attachment while precluding deformation of the cable, which disrupts electrical performance.

  • Patent number: 8371788
    Abstract: A fastener for securing an undercover panel to an underside of a vehicle is disclosed. The fastener includes a body having a bore for receiving a threaded bolt extending from the underside of the vehicle, a flange for engaging a first side of the undercover panel, a plurality of resiliently deformable engaging fingers for allowing insertion of the bolt into the bore and to resist removal of the bolt from the bore, and a plurality of resilient engaging members for enabling the engaging members to pass in a first direction through an aperture in the undercover panel, and to resist removal of the fastener from the panel. A plurality of reinforcing members extend from the body to engage a respective engaging member, as a result of forces urging said undercover panel towards the underside of the vehicle, to resist flexing of the engaging members away from the body.

  • Patent number: 8348578
    Abstract: An engagement unit for insertion on and engagement with a threaded bolt (33) is provided with an inner part (1) and with an outer part (2) that can be slid onto the inner part (1). The inner part (1) and the outer part (2) are configured with torque receiving means (8, 9, 23, 24) for transmitting a torque applied to the outer part (2) to the inner part (1). After the inner part (1) has been slid onto a threaded bolt (33) in a pre-assembly arrangement in which latching means configured on spring arms of the inner part (1) and cooperating with the threaded bolt (33) are able to slide along the threaded bolt (33), the engagement unit according to the invention can thus be inserted onto the threaded bolt (33) and, once the outer part (2) has been slid onto the inner part (1), can be tightened in the manner of a screw.

  • Patent number: 8328482
    Abstract: A tensioner for tensioning foundation bolts generally used in securing large utility towers is provided. The tensioner generally comprises a hollow outer body through which the foundation bolt can extend. The lower end of the body, which is adapted to abut onto the foundation surface from which the bolt extends, is provided with an opening allowing access to a foundation nut threaded onto the foundation bolt. The upper end of the outer body slidingly receives therein an inner body with which it defines an annular hydraulic piston, the inner body being configured with a seat portion for receiving and engaging a split nut mounted to the foundation bolt. Upon providing hydraulic fluid to the tensioner, the hydraulic piston urges the split nut, engaged to the foundation bolt, upwardly, thereby tensioning the foundation bolt. The load in the bolt is then maintained by threading down the foundation nut until it abuts onto the foundation surface.
