Abstract
Abstract In accordance with an illustrative embodiment of the present invention, an electrical connector assembly to connect the end of a seismic cable to a data acquisition unit includes a body member having a plurality of sockets in one end which react with pins on a companion receptacle. A tubular shell which is rotatably mounted on the body member has threads that make up with threads on the receptacle, and a drive ring which engages a shoulder on the body member to force the sockets onto the pins as thread make-up takes place. As the threads are released, the drive ring moves back into engagement with an opposed shoulder on the body member to positively separate the sockets and pins.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
260 words
In an electrical connector assembly having a pair of connector body members with confronting end faces, said members having pin and socket means for making electrical connections, one of said members having first axial cam means, comprising: tubular means rotatably mounted on the other of said body members and having second axial cam means cooperable with said first axial cam means to force said tubular means axially toward said one body member in response to relative rotation in one hand direction to engage said socket and pin means; coengageable first drive means on said tubular means and said other body member for pushing said other body member axially toward said one body member to cause engagement of said pin and socket means with one another and to forcefully engage said confronting faces in response to said relative rotation, said first drive means including a rearwardly facing shoulder on said other body member, an internal radial groove in said tubular means, and a drive ring mounted partially in said groove and arranged to engage said shoulder; coengageable second drive means on said tubular means and said other body member for pulling said other body member away from said one body member to at least partially release said pin and socket means in response to relative rotation in the opposite hand direction; and means forming a lost-motion coupling in connection with said first and second drive means to allow partial release of said axial cam means before the said pulling of said other body member away from said one body member begins.
Claim 2
Dependent Claim
260 words
In an electrical connector assembly having a pair of connector body members with confronting end faces, said members having pin and socket means for making electrical connections, one of said members having first axial cam means, comprising: tubular means rotatably mounted on the other of said body members and having second axial cam means cooperable with said first axial cam means to force said tubular means axially toward said one body member in response to relative rotation in one hand direction to engage said socket and pin means; coengageable first drive means on said tubular means and said other body member for pushing said other body member axially toward said one body member to cause engagement of said pin and socket means with one another and to forcefully engage said confronting faces in response to said relative rotation, said first drive means including a rearwardly facing shoulder on said other body member, an internal radial groove in said tubular means, and a drive ring mounted partially in said groove and arranged to engage said shoulder; coengageable second drive means on said tubular means and said other body member for pulling said other body member away from said one body member to at least partially release said pin and socket means in response to relative rotation in the opposite hand direction; and means forming a lost-motion coupling in connection with said first and second drive means to allow partial release of said axial cam means before the said pulling of said other body member away from said one body member begins.
Claim 3
Dependent Claim
28 words
The assembly of claim 1 wherein said shoulder is formed at the intersection of a greater diameter portion of said other member and a lesser diameter portion thereof.
Claim 4
Dependent Claim
239 words
An electrical connector assembly adapted for use in seismic operation to connect the end of a multi-conductor cable to a data acquisition unit, comprising: a cylindrical body member having a plurality of sockets therein which open through the outer face thereof; a receptacle member including a base having a corresponding plurality of pins mounted thereon which are adapted to mate with said sockets, said base having a tubular portion which surrounds said pins; an elongated tubular shell rotatably mounted on said body member and movable longitudinally relative thereto between first and second positions, said shell having a reduced diameter front end portion; axial cam means on said front end portion and said tubular portion for forcing said portions into telescoping engagement in response to relative rotation in one hand direction; first drive means including a drive ring within said shell engageable with a first shoulder on said body member and operable in said first position for causing said body member to move axially with said shell toward said receptacle to engage said sockets with said pins; and second drive means including said drive ring and a second shoulder on said body member to move axially with said shell away from said receptacle to at least partially disengage said sockets from said pins, said shoulder being axially spaced to provide lost-motion axial movement of said shell relative to said body means between engagement of said first and second drive means.
Claim 5
Dependent Claim
239 words
An electrical connector assembly adapted for use in seismic operation to connect the end of a multi-conductor cable to a data acquisition unit, comprising: a cylindrical body member having a plurality of sockets therein which open through the outer face thereof; a receptacle member including a base having a corresponding plurality of pins mounted thereon which are adapted to mate with said sockets, said base having a tubular portion which surrounds said pins; an elongated tubular shell rotatably mounted on said body member and movable longitudinally relative thereto between first and second positions, said shell having a reduced diameter front end portion; axial cam means on said front end portion and said tubular portion for forcing said portions into telescoping engagement in response to relative rotation in one hand direction; first drive means including a drive ring within said shell engageable with a first shoulder on said body member and operable in said first position for causing said body member to move axially with said shell toward said receptacle to engage said sockets with said pins; and second drive means including said drive ring and a second shoulder on said body member to move axially with said shell away from said receptacle to at least partially disengage said sockets from said pins, said shoulder being axially spaced to provide lost-motion axial movement of said shell relative to said body means between engagement of said first and second drive means.
Claim 6
Dependent Claim
31 words
The assembly of claim 3 wherein said lost-motion is provided by an axial separation of said shoulders by a distance which is substantially greater than the thickness of said drive ring.
Claim 7
Dependent Claim
12 words
The assembly of claim 3 wherein said axial cam means are threads.
