  • Patent number: 10122158
    Abstract: The invention relates to a corrugated tube made of flexible plastic for encasing wires, having circumferential, successively alternating corrugation crests and corrugation troughs distributed over the axial length thereof, wherein the corrugation crests, seen in cross-section, perpendicular to the longitudinal axis of the corrugated tube, each have a corrugation along the outside circumference thereof which forms alternating radially protruding regions and radially inward-offset regions in the circumferential direction of each corrugation crest. The corrugated tube has wall sections, which extend axially over the length thereof and lie adjacent to each other in the circumferential direction, of which wall sections one forms the radially protruding regions in the corrugation and the other forms the radially inward-offset regions. Said wall sections consist of materials of varying hardness in circumferential alternation.

  • Patent number: 10115502
    Abstract: A dielectric cover for an insulator and conductor in an electrical distribution includes an insulator cover portion for covering the insulator. A knob and ridge extend down from an inside ceiling of the insulator cover portion. An arm, for covering a portion of the conductor extending from the insulator, has a top keyhole, where the keyhole has a wide portion that fits over the knob in a first position and a narrow portion that restricts vertical movement of the arm in a locked position when the arm is withdrawn slightly. The arm also has a resilient tab that snaps over the ridge in the locked position, wherein the knob in combination with the keyhole restrict further withdrawing of the arm from the insulator cover portion in the locked position, and the tab contacting the ridge restricts further insertion of the arm into the insulator cover portion in the locked position.

  • Patent number: 10109944
    Abstract: A protective guard prevents undesired access to a wall-mounted electrical interface such as an electrical switch or outlet, particularly by small children. The protective guard includes a baseplate, cover and spring-biased latch. The baseplate is mounted to the wall and contains at least one opening to expose the electrical interface. The cover slidably attaches to the baseplate for sliding movement between a closed position that blocks access to the electrical interface and an open position that exposes the electrical interface. The spring-biased latch is attached to the cover. The latch is actively spring-biased to a locked position that holds the cover in the closed position and has an unlocked position offset from the locked position which allows sliding movement of the cover to its open position to expose the electrical interface. Advantageously, exposing the electrical interface requires no additional parts or tools that should be procured, removed, stored, or could be misplaced.
