Abstract:
A removable socket assembly (36, 44) for an electrical connector (10, 18) in a take-out assembly for a seismic cable (11). The socket assembly (36, 44) has a receptacle (50) receiving a socket (52) in a threaded relation. Base (68) of socket (52) has a bore (82) of a hexagonal cross section and a tool (90) of a hexagonal cross section is received within bore (82) in a mating relation for removal and replacement of socket (52) in the event of malfunctioning.
Abstract:
A connector is described that allows the connector main part (16, FIG. 2) to be pulled out of a coupling nut or part (24) when the cable (20) that extends rearwardly from the main part, is pulled with a large force. The main part is of the type that includes a metal shell (30) enclosing an insulator (32) that holds contacts (34) whose front ends mate with the contacts of a mating connector device (14) and whose rear ends connect to wires of the cable. The outside of the shell and the inside of the coupling part have adjacent grooves (56, 54), and an expandable ring-shaped retainer (52) lies in both grooves to normally hold the main part to the coupling part. The forward wall (74, FIG. 3) of the groove in the main part is inclined from an axial direction to form a ramp. If the main part is pulled rearwardly with a large force, the retainer expands as it rides up the ramp and past the front of the main part, to thereby release the main part from the coupling part and the connector device to which it is coupled.
Abstract:
A pigtail-type takeout on a seismic cable including a molded elastomer Y-body, a pigtail and a multi-contact connector for connecting the end of a geophone string to the cable. The connector body includes a longitudinally split inner tubular portion that is fitted around the cable, and tie wraps are used to encircle and hold the tubular portion tightly around the cable to firmly mount the connector body thereon.
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.
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.
Abstract:
The present invention provides a ruggedized heavy duty source connector adapted for use on large air guns. The source connector comprises reinforcing fibers in the cable jacket that are anchored to the connector front shell, an external blast shield in place of a rear shell, and a fatigue resistant strain relief overmold.
Abstract:
A connector for a seismic data acquisition cable includes a molded plastic connector body. The connector body has inserted therein at least one electrical contact for mating with a corresponding electrical contact. The connector body has an internal opening for receiving an electrical cable. The connector body has a mating surface adapted to contact a corresponding connected structure. The internal opening is filled with a curable compound which upon cure forms a substantially interface free bond with the connector body and an external jacket of the electrical cable.

Abstract:
An improved termination connector for seismic cable, the improvement including a reduced rigid length and improved flexibility by making connector to cable conductor splice connection within the bend restrictor, further reducing failure due to lateral stress through the use of a split collar and sleeve arrangement for connecting the connector's rotatable nut assembly to the connector body. The instant connector improves pin to cable makeup with improved pressure compensation splice connection process.
Abstract:
An electrical conducting connector used to interconnect medical electrodes and monitoring devices. The male stud, commonly manufactured on the electrode, is relocated to a new position as an integral part of the connector. Consequently, the connector can act as an adapter for electrically interconnecting a relatively inexpensive, flexible, studless electrode secured on the skin of a patient to a monitor having a conventional lead wire plus female couple assembly. Such interconnection allows rotation between the connector and electrode, thereby assuring patient comfort and continued electrical contact even when the electrode is adhered to the patient for long periods of monitoring.
