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.
