A method and apparatus of making a splice in a geophone cable for providing a weatherproof cable splice with maximum cable break strength. The ends of each of the cables are soldered to a printed circuit board to provided the necessary cable strength. The printed circuit board is covered by a silicone rubber boot which sealingly engages the ends of each of the cables on either side of the printed circuit board to insure moisture protection.

A geophone cable splice comprising, a printed circuit board having at least two spaced apart electrical conductive lands bonded to an electrical nonconductive base, first and second round cables, each of said cables having at least first and second round electrical conductors said first conductors of each of said cables soldered to one of the electrical lands and said second conductors of each of said cables soldered to another electrical land, and a resilient boot having an opening therethrough, said opening enclosing the printed circuit board with one end of the boot sealingly engaging the first cable and the other end of the boot sealingly engaging the second cable. The method of splicing two round geophone cables together, each of which have an outer round jacket, and at least first and second insulation-covered round electrical conductors comprising, stripping the outer jackets of the ends of the cables to be spliced. stripping the insulated covers from the ends of the electrical conductors; soldering the first stripped conductors to a conductive land which is bonded to an electrically nonconductive base of a printed circuit board, soldering the second stripped conductors to a second conductive land which is bonded to be base of the printed circuit board, and sliding a resilient boot having an opening therethrough over the cables and the printed circuit board with a lubricant located between the boot and the cables in which the ends of the opening have a normal size of less than the outside circumference of the cables.
