Abstract
A connecting module for connecting seismic equipment towed in water, includes a housing having first and second ends opposite to each other, a removable connecting part removably attached to the first end of the housing, an integral connecting part integrally made with the housing at the second end, the integral connecting part having a bore, and one or more pins configured to enter from an outside of the integral connecting part into the bore. An end of the one or more pins has a conical surface that is configured to transfer a radial force FR applied to the one or more pins, as a longitudinal force FL to an electrical insert to be placed in the bore.

A connecting module for connecting seismic equipment towed in water, the connecting module comprising:
- a housing extending along a longitudinal axis X so that first and second ends are opposite to each other;
- a removable connecting part removably attached to the first end of the housing;
- an integral connecting part integrally made with the housing at the second end, the integral connecting part having a bore;
- and
- one or more pins configured to enter from an outside of the integral connecting part into the bore,
- wherein an end of the one or more pins has a conical surface that is configured to transfer a radial force FR applied to the one or more pins, as a longitudinal force FL to an electrical insert to be placed in the bore, and
- wherein the radial force FR is applied along a radial axis of the housing and the longitudinal force FL is applied along the longitudinal axis X.
A connecting module for connecting seismic equipment towed in water, the connecting module comprising:
- a housing extending along a longitudinal axis X so that first and second ends are opposite to each other, the housing defining a sealed chamber;
- electronics located within the chamber;
- an integral connecting part integrally made with the housing at the second end, the integral connecting part having a bore;
- an electrical insert located within the bore and configured to electrically or optically connect to the electronics;
- and
- one or more pins configured to enter from an outside of the integral connecting part into the bore, through a wall of the integral connecting part,
- wherein an end of the one or more pins has a conical surface that is configured to transfer a radial force FR, applied on the one or more pins, as a longitudinal force FL to the electrical insert.
A method for connecting a first streamer section to a second streamer section, the method comprising:
- providing a connecting module having a housing that extends along a longitudinal axis X so that first and second ends are opposite to each other, the housing defining a sealed chamber, wherein an integral connecting part is integrally made with the housing at the second end, the integral connecting part having a bore;
- electrically or optically connecting electronics with an electrical insert;
- inserting the electronics and the electrical insert into the connecting module so that the electrical insert sits inside the bore and the electronics sits inside the chamber;
- inserting one or more pins, from an outside of the integral connecting part, toward the bore, through a wall of the integral connecting part;
- and
- tightening the one or more pins so that an end of the one or more pins, which has a conical surface, enters the bore and transfers a radial force FR, applied on the one or more pins, as a longitudinal force FL to the electrical insert.
