Abstract
Abstract In accordance with an illustrative embodiment of the present invention, a connector assembly for plugging geophones into a leader cable includes rigid thermoplastic inserts that are positioned within molded polyurethane bodies and molecularly bonded thereto. The male connector member carries a replaceable silicone O-ring seal in an external annular groove therein which engages an internal annular recess on the female body when the connection is made up. The seal keeps out moisture, and releasably couples the connector members together.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
165 words
A seismic connector assembly comprising: a first connector means including a male insert member bonded within a first tubular body having an outer end, said male insert member having an outer portion extending beyond said outer end of said body; a second connector means including a female insert member having an outer face and being bonded within a second tubular body, an outer portion of said second tubular body extending beyond said outer face of said female insert member, said outer portion of said male insert member being arranged to be received within said outer portion of said second tubular body when said connector assembly is made up; internal annular recess means on said outer portion of said second tubular body; and replaceable seal ring means on said outer portion of said male insert member arranged to engage said recess means when said connector assembly is made up to prevent the entry of moisture and to releasably hold said first and second connector means together.
Claim 2
Dependent Claim
165 words
A seismic connector assembly comprising: a first connector means including a male insert member bonded within a first tubular body having an outer end, said male insert member having an outer portion extending beyond said outer end of said body; a second connector means including a female insert member having an outer face and being bonded within a second tubular body, an outer portion of said second tubular body extending beyond said outer face of said female insert member, said outer portion of said male insert member being arranged to be received within said outer portion of said second tubular body when said connector assembly is made up; internal annular recess means on said outer portion of said second tubular body; and replaceable seal ring means on said outer portion of said male insert member arranged to engage said recess means when said connector assembly is made up to prevent the entry of moisture and to releasably hold said first and second connector means together.
Claim 3
Dependent Claim
41 words
The assembly of claim 1 wherein said male and female members each have at least one pin and at least one socket arranged therein so that said pins and sockets mate with one another when said connector means are made up.
Claim 4
Dependent Claim
42 words
The assembly of claim 1 further including a leader cable having at least one pair of conductor wires therein; and means for mounting said first connector means in a laterally offset position with respect to the longitudinal axis of said leader cable.
Claim 5
Dependent Claim
83 words
The connector assembly of claim 1 wherein said male and female insert members are made of a rigid thermoplastic material having external surfaces that are molecularly bonded to adjacent surfaces of said first and second tubular bodies; external annular groove means in the outer wall of said outer portion of said male insert member arranged to receive said replaceable seal ring means, said material of said male insert member providing relatively hard walls for said groove means to retain said seal means therein.
Claim 6
Dependent Claim
15 words
The assembly of claim 4 wherein said replaceable seal ring means is a silicone O-ring.
Claim 7
Dependent Claim
85 words
The assembly of claim 4 wherein said end portion of said second tubular body has an internal chamfered surface adjacent the outer end face thereof, said internal annular recess being spaced axially inward of said chamfered surface, said second tubular body being made of a resilient thermoplastic material so that as said connector means are made up said chamfered surface coacts with said seal ring means to cause expansion of said end portion to allow said seal means to engage said internal annular recess means.
Claim 8
Dependent Claim
33 words
The assembly of claim 4 wherein said groove means has width and depth dimensions that are sized to prevent roll-out of said seal ring means during engagement and disengagement of said connector means.
Claim 9
Dependent Claim
133 words
A male seismic connector adapted to make an electrical connection between a geophone and a leader cable, comprising: a generally tubular molded elastomer body having an open outer end and an internal cavity extending inward from said open outer end; a generally cylindrical, rigid thermoplastic insert member having an outer end portion, said member being mounted partially in said cavity so that said outer end portion of said insert member extends outside said cavity and beyond said open outer end of said body, the outer surfaces of said insert member which are within said cavity being molecularly bonded to adjacent inner surfaces of said body, said insert member having electrical pin and socket means; an external annular groove in said outer end portion; and a replaceable silicone O-ring seal mounted in said groove.
Claim 10
Dependent Claim
133 words
A male seismic connector adapted to make an electrical connection between a geophone and a leader cable, comprising: a generally tubular molded elastomer body having an open outer end and an internal cavity extending inward from said open outer end; a generally cylindrical, rigid thermoplastic insert member having an outer end portion, said member being mounted partially in said cavity so that said outer end portion of said insert member extends outside said cavity and beyond said open outer end of said body, the outer surfaces of said insert member which are within said cavity being molecularly bonded to adjacent inner surfaces of said body, said insert member having electrical pin and socket means; an external annular groove in said outer end portion; and a replaceable silicone O-ring seal mounted in said groove.
Claim 11
Dependent Claim
151 words
A female seismic connector member adapted to make an electrical connection between a geophone and a leader cable, comprising: a generally tubular molded elastomer body having an open outer end portion, said body having an internal cavity extending from said open outer end portion; a generally cylindrical, rigid thermoplastic insert member having front, rear and outer walls and being mounted completely within said cavity and in a manner such that said outer end portion of said tubular body extends beyond said front wall of said insert member, said outer and rear walls of said insert member being molecularly bonded to adjacent inner surfaces of said body, said insert member having electrical pin and socket means; and an internal annular recess means on said outer end portion of said tubular body for receiving the outer portion of a seal ring mounted on a mating male connector member that prevents entry of moisture.
Claim 12
Dependent Claim
151 words
A female seismic connector member adapted to make an electrical connection between a geophone and a leader cable, comprising: a generally tubular molded elastomer body having an open outer end portion, said body having an internal cavity extending from said open outer end portion; a generally cylindrical, rigid thermoplastic insert member having front, rear and outer walls and being mounted completely within said cavity and in a manner such that said outer end portion of said tubular body extends beyond said front wall of said insert member, said outer and rear walls of said insert member being molecularly bonded to adjacent inner surfaces of said body, said insert member having electrical pin and socket means; and an internal annular recess means on said outer end portion of said tubular body for receiving the outer portion of a seal ring mounted on a mating male connector member that prevents entry of moisture.
