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 geophone connector assembly includes a body having a socket that includes a tubular mandrel, a female contact assembly positioned in the mandrel and having resilient fingers surrounded by a sleeve member and arranged to receive the pin of a mating connector, and a threaded bore in the mandrel arranged to receive a threaded shank on the inner end of the female contact assembly to enable removal and replacement of the contact assembly as a unit in the field in the event of damage thereto.

Abstract: A combination seismic cable handling loop and electric splice includes a U-shaped elastomer member arranged to be hung on a hasp during transportation and storage, and an integrally formed cylindrical elastomer body on the lower end of the U-shaped member which encloses a splice card by which electrical conductors in the end portions of seismic cable sections are joined, such end portions extending through the outer portions of the body which provides strain relief.

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: The male connector plug has a cylindrical body portion which has a forward cylindrical section of a smaller diameter and a rear cylindrical section of a larger diameter. Each such body section is surrounded by an O-ring. The mating female connector plug has a tubular body portion whose bore defines a forward cylindrical bore section of a larger-diameter and a rear cylindrical bore section of a smaller diameter. Each bore section has an annular groove therein.

Abstract: The T-coupler has a casing from which extends at least one sleeve having a tubular wall, a rear wall, a port, and a connector chamber formed between the rear wall and the port. First connector contacts are arranged on the rear wall of the sleeve. Conductors within the casing electrically interconnect the first contacts to provide polarized circuit paths therebetween. A connector element carries mating second contacts. A forwardly-tapering resilient sealing grommet and a forwardly-tapering anchoring grommet are provided in the connector chamber. A seismic leader cable extends through the longitudinal bores in the anchoring and sealing grommets. The conductors of the cable are electrically connected to respective ones of the second contacts in the connector. An end cap is adapted to become secured to the forward portion of the sleeve to thereby anchor the cable to the anchoring grommet, and to seal off the connector chamber against moisture penetration.

Abstract: The double-plug seismic electric connector comprises an elongated insulating body. A male connector plug is at one end of the body and a female connector plug is at the opposite end of the body. Each plug has a pair of male and female contacts. A pair of spaced axial conductors is embedded within the insulating body for interconnecting the opposite male and female contacts. The inner end of a double-wire cable is embedded within the insulating body and each wire inner end is connected to one of the conductors.
