  • Patent number: 11538608
    Abstract: A wire harness includes an electric wire, a braided conductor covering the electric wire, a grommet having a tubular insertion portion through which the electric wire and the braided conductor are inserted, a water stop sheet sandwiched between an inner peripheral surface of the insertion portion and the braided conductor, and a fixture attached to the insertion portion so as to reduce a diameter of the insertion portion. The water stop sheet includes a base material layer having a plurality of pores communicating with each other in a thickness direction of the water stop sheet and a sealing compound layer laminated on the base material layer. The sealing compound layer is deformed so as to enter gaps between thin conductor wires constituting the braided conductor and the pores of the base material layer.

  • Patent number: 9787069
    Abstract: A structure for mounting a retrofit part to a cladding member may be used to prevent the retrofit part from causing a turn or positional displacement. For example, a clamp structure may include a clamp base and a clamp cover continuous to the clamp base by a hinge. The clamp may further include projections such as spike-shaped portions. The spike-shaped portions are formed and placed on both a mount surface of the clamp base and a mount surface of the clamp cover. The spike-shaped portions may prevent the clamp from causing a turn or positional displacement, and may be each protrusively formed substantially into a pyramid shape with a pointed end. The spike-shaped portions are formed to bite into an exterior surface of a cladding member and that resists external force, such as vibrations, when the clamp is mounted.
