Embodiment approach

[0039] According to one embodiment of the present invention, the first connection assembly includes a first support 41 and a first housing 31 , the peripheral side of the first support 41 is provided with raised lines 411 , and the wire 8 runs through the inside of the first support 41 , the first housing 31 is sheathed on the peripheral side of the first supporting member 41 , and the first housing 31 is connected to the pipe member 6 .

[0040] The peripheral side of the first supporting member 41 is connected with the inner side of the first housing 31 by setting the embossing 411. The embossing 411 increases the contact area between the first supporting member 41 and the first housing 31, and at the same time The movement of the support member 41 along the axial direction of the first housing 31 acts as a limiter, which improves the fixing effect of the first support member 41 on the position of the wire 8 , thereby improving the tensile capacity of the wire 8 .

Abstract

The invention provides an oil-filled watertight connecting device and equipment, the oil-filled watertight connecting device comprises a first contact unit, a second contact unit, a wire and a pipe fitting, the first contact unit comprises a first connecting assembly and a plurality of first contact pieces, the plurality of first contact pieces are embedded in the first connecting assembly, the second contact unit comprises a second connecting assembly and a plurality of second contact pieces, the second contact pieces are embedded in the second connecting assembly, and the first connecting assembly and the second connecting assembly are connected to pipe openings in the two ends of the pipe fitting correspondingly so that a sealed cavity can be formed in the pipe fitting. By arranging the wire of which the two ends are respectively connected to the first contact piece and the second contact piece in the cavity filled with the oil in the pipe fitting, the inner side oil pressure of the pipe fitting is almost equal to the outer side water pressure of the pipe fitting, the inner pressure and the outer pressure of the pipe fitting are balanced, and the self stress is almost zero; and the problem in the prior art that the outer sheath of the watertight cable is easy to damage due to high water pressure due to the fact that the wire is directly wrapped by the watertight cable is solved.

Description

technical field [0001] The invention relates to the technical field of electric conduction, in particular to an oil-filled watertight connection device and equipment. Background technique [0002] With the rapid development of the industry for the development and utilization of marine resources and the marine environment, the demand for various underwater equipment is becoming more and more urgent. As a key component in the electromechanical system of underwater instruments, watertight electrical connectors are used in underwater instruments. It acts as a mechanical and electrical signal connection in the device. [0003] The underwater part of the existing watertight electrical connector is mainly to complete the interconnection between different underwater equipment through the watertight cable to realize the function of electrical transmission, but the existing watertight cable is under the long-term action of high water pressure Covers are easily damaged.
