Problems solved by technology

However, it is also difficult to meet the requirements in practical engineering applications, especially when towing large-scale detection equipment, the underwater motion state of the towed cable is very complicated, and the electrical connector and cable joint are not only subjected to tension, but also torsion and bending. , under the action of this composite force, it is also difficult to ensure the watertightness between the cable body and the metal joint
On the other hand, after the assembly is completed, the watertight structure will be encapsulated in the electrical connector, and even if it passes the hydrostatic test, it cannot be confirmed that its sealing is reliable

Abstract

The invention discloses an anti-twist watertight device for an underwater electric connector and belongs to the field of marine geophysical prospecting. The device comprises a metal connector, an adjusting tube, an outer metal housing, a first conical part, a first rubber pad, an isolating ring, a second rubber pad, a second conical part, a conical cover, a steel wire sheath mounting plate, a rubber ring, a transition ring, a concave ring, a flared steel wire mesh cover, a rubber jacket, a locking nut, a hollow wedged column, strength bearing aramid fibers and an inner wedged positioning column. Peripheral equipment includes cables. The isolating ring is arranged between the rubber pads to enable the rubber pads to form a serial connection structure, sealing similar to a labyrinth is formed, and sealing performance at the rubber pads is improved. Further, the sealing connector and the cables are high in connection strength and anti-twist performance.

Description

technical field [0001] The invention relates to a watertight device for a torsion-resistant underwater electrical connector, which belongs to the field of marine geophysical exploration. Background technique [0002] Trailing cables have been widely used in the marine geophysical industry, and the quality of watertight electrical connectors for underwater cables plays a key role. Due to the complex working conditions of the electrical connector, the sealing degree is required to be high, and once the electrical connector leaks, the cable will be damaged in the lightest case, and the operator will be injured in the serious case. To this end, engineers and technicians have designed and manufactured various watertight structures suitable for different working conditions, some of which have been listed as standard products, and their varieties have been serialized. However, it is difficult to meet the application requirements in practical engineering applications, especially wh...
