  • Patent number: 10573436
    Abstract: A liquid-tight strain relief includes a tubular-shaped bushing and a dome-shaped gland. The bushing includes a flange with arcuate slots, a centrally-located aperture, a plurality of resilient outer fingers, and a shoe slideably received within a lateral groove of the bushing. The gland includes a head having a centrally-located membrane. The head is co-molded with and encapsulates the flange, resulting in a strain relief having a unitary construction. The strain relief is adapted to be inserted within an orifice of a work piece, and the outer fingers frictionally engage the work piece. A cable is inserted within the strain relief by puncturing the membrane, which then stretches and provides a seal against the cable. The cable is gripped to the strain relief when the shoe is pressed against the cable. The shoe is held against the cable by teeth on the shoe, which engage opposing locking ribs on the bushing.

  • Patent number: 10571054
    Abstract: A preassembled pipe coupling and method for joining pipe segments in an end-to-end relationship. The coupling (100) includes three identical housing segments (110) joined end to end. Each housing segment (110) includes a pipe engagement surface defining a radius of curvature. The radii of curvature of the three housing segments (110) are identical. The third housing segment is connected to the first and second housing segments to define a first configuration and a second configuration of the coupling, in which the radii of curvatures are the same in the first and second configurations. In the first configuration, the three housing segments (110) are radially located about an annular gasket (400) to permit insertion of the pipe segment into the gasket (400). In the second configuration, the three housing segments are radially located about the annular gasket such that the gasket is compressed to form a fluid tight seal and the pipe engagement surfaces engage the outer surface of the pipe segment.

  • Patent number: 10563800
    Abstract: An apparatus for coupling together tubular components is described herein. The apparatus includes a coupling assembly with a coupling device having threads and an internal groove. The coupling assembly also includes a retainer clip positionable in the internal groove. The retainer clip is biased to apply a radially outward force against the internal groove when the retainer clip is positioned in the internal groove. The coupling assembly includes a ferrule, coupleable to the coupling device, in contact with the retainer clip when coupled to the coupling device to form an electrically conductive path through the coupling device, the retainer clip, and the ferrule. The retainer clip is configured to prevent movement of the coupling device relative to the ferrule when the retainer clip has an unbiased inner diameter smaller than an outer diameter of the ferrule or the retainer clip is not properly inserted into the internal groove.
