  • Patent number: 7931386
    Abstract: A flexible lighting strip includes an insulated flexible electrical power cord and spaced apart modules connected therewith. Each module includes a circuit board with a cavity, indentation, or opening and an encasing overmolding defining a fastener-receiving slot or opening aligned with the cavity, indentation, or opening of the circuit board. Power cord conductors are separated at the connection with each module to define a gap receiving a portion of the circuit board. A separate tiedown is secured to the power cord. Conductive elements receiving electrical power from the power cord and delivering electrical power to the circuit board include an insulation-displacing portion and a recess receiving at least a portion of the power cord and including a retaining barb or hook. An adhesive tape or strip is disposed over at least one overmolding opening to prevent water ingress to the circuit board.
