A connecting module for seismic equipment towed in water has been patented, comprising a housing with removable and integral connecting parts, one or more pins transferring radial force as longitudinal force to an electrical insert. The electrical insert sits against a shoulder of the integral connecting part and directly contacts the pins, with matching conical surfaces at a 45-degree angle to the longitudinal and radial axes. Electronics in the chamber are coupled to the electrical insert, with additional components like spacers and rings for secure assembly.

Another aspect of the patented connecting module involves a method for connecting streamer sections, where a housing with a sealed chamber and integral connecting part is used. Electronics are connected to an electrical insert, inserted into the module, and secured by pins transferring radial force as longitudinal force to the insert. The method ensures the radial force is applied along the housing's radial axis, while the longitudinal force is along the longitudinal axis, providing a reliable connection for towing seismic equipment in water. Additional steps include tightening the pins and ensuring proper alignment for effective transfer of forces.
