  • Method for waterproofing junction of main and branch wires and cover therefor
    Patent number: 5410105
    Abstract: A method for waterproofing a junction of branch wires with a main wire by enclosing the junction in a plastic cover containing a putty sealant and filling the inside of the cover with the sealant and a cover therefore are disclosed, the method comprising providing projections n and m on the inner side of cover l by which parallel wires b enfolded in the cover are vertically shifted or the parallel wires are not only vertically shifted but laterally spread by the projections to make enough space between adjacent wires b for letting the putty sealant in.

  • Sealing method for electric wire connection
    Patent number: 5358588
    Abstract: A method of using a sealing material for an electric wire connection, comprising a tape-form releasable material, viscous sealing pieces comprising a waterproofing compound, each piece having a width narrower than the width of the releasable material and being releasably formed on one surface of the releasable material, and a sheet-form base material having a larger area than the viscous sealing piece such that each end of the base material projects over each edge portion of the viscous sealing piece formed in one body on each viscous sealing piece. The method includes supplying the sealing material from a tape-form releasable material, the sealing material provided thereon at a constant interval covering the electric wire connection, and pressing the sealing material to adhere to the surfaces of the electric wires.
