Claim 2

In combination: a connector insulator disc having a dielectric element and flat conductive strips on one face of the element, the strips being arranged in spaced insulated relation, the dielectric element having a pair of transverse holes which extend between the opposite faces of the disc and through a pair of particular conductive strips; and a seismic detector having a pair of external terminals, each terminal extending through a particular corresponding hole and through the conductive strip surrounding such hole.

Claim 3

Claim 4

The combination of claim 1, wherein the disc is circular and is positioned above and outside of the casing of the detector.

Claim 5

The combination of claim 2, wherein the disc is circular and the disk and said conductors are separable from the detector by unsoldering only the detector's terminals from their associated conductive strips.

Claim 6

In combination: a circular connector disc having a dielectric element and flat conductive strips on one face of the element, the strips being arranged in spaced insulated relation, the dielectric element having a pair of transverse holes which extend between the opposite faces of the disc and through a pair of particular conductive strips; a seismic detector having a pair of external terminals, each terminal extending through a particular corresponding hole and through the conductive strip surrounding such hole; a pair of cables, each cable having at least two conductors, each conductor having a bare end which is disposed over and substantially parallel to a particular conductive strips; and solder means galvanically and mechanically anchoring each bare end to its associated conductive strip, said solder means galvanically connecting each detector terminal to its associated strip, whereby each bare end is mechanically anchored to the disc so that the disc can withstand and resist longitudinal pulls on the cables in a direction away from the detector.

Claim 7

In combination: a circular connector disc having a dielectric element and flat conductive strips on one face of the element, the strips being arranged in spaced insulated relation, the dielectric element having a pair of transverse holes which extend between the opposite faces of the disc and through a pair of particular conductive strips; a seismic detector having a pair of external terminals, each terminal extending through a particular corresponding hole and through the conductive strip surrounding such hole; a pair of cables, each cable having at least two conductors, each conductor having a bare end which is disposed over and substantially parallel to a particular conductive strips; and solder means galvanically and mechanically anchoring each bare end to its associated conductive strip, said solder means galvanically connecting each detector terminal to its associated strip, whereby each bare end is mechanically anchored to the disc so that the disc can withstand and resist longitudinal pulls on the cables in a direction away from the detector.

Claim 8

The combinatin of claim 5, and a hollow housing having an internal chamber dimensioned to house said detector; and cover means removably enclosing said detector, said disc, and said cables within said casing.

Claim 9

In combination: a flat, dielectric, circular connector disc; a geophone having a pair of external terminals; and a pair of geophone leader cables; said disc having on one face thereof conductive strips, a pair of longitudinal holes extending between the opposite faces of the disc and extending through a pair of particular conductive strips, said conductive strips interconecting said cables between themselves and with the geophone's external terminals; each cable having at least a pair of conductors, each conductor having a plurality of wire strands, the bar end of each conductor being filled with solder, thereby anchoring the conductor's bare end to a particular conductive strip on the disc; a housing having a chamber, the geophone being housed inside the chamber; an insulating elastic sleeve coupling the disc to the top end of the geophone, the sleeve having an I-shaped cross-section and defining an upper cylindrical chamber, a lower cylindrical chamber, said sleeve chambers having a common wall defining a pair of longitudinal holes therein; the top end of the geophone being positioned within said lower chamber and the disc resting within said upper chamber on top of said common wall, the disc being oriented so that the geophone's terminals extend through the holes in said common wall and through the holes in said disc; the cylindrical wall of said sleeve's upper chamber having a pair of diametrically-opposed openings through which extend said cables; and a cover for said casing to waterproof said casing chamber.

Claim 10

In combination: a flat, dielectric, circular connector disc; a geophone having a pair of external terminals; and a pair of geophone leader cables; said disc having on one face thereof conductive strips, a pair of longitudinal holes extending between the opposite faces of the disc and extending through a pair of particular conductive strips, said conductive strips interconecting said cables between themselves and with the geophone's external terminals; each cable having at least a pair of conductors, each conductor having a plurality of wire strands, the bar end of each conductor being filled with solder, thereby anchoring the conductor's bare end to a particular conductive strip on the disc; a housing having a chamber, the geophone being housed inside the chamber; an insulating elastic sleeve coupling the disc to the top end of the geophone, the sleeve having an I-shaped cross-section and defining an upper cylindrical chamber, a lower cylindrical chamber, said sleeve chambers having a common wall defining a pair of longitudinal holes therein; the top end of the geophone being positioned within said lower chamber and the disc resting within said upper chamber on top of said common wall, the disc being oriented so that the geophone's terminals extend through the holes in said common wall and through the holes in said disc; the cylindrical wall of said sleeve's upper chamber having a pair of diametrically-opposed openings through which extend said cables; and a cover for said casing to waterproof said casing chamber.
