Embodiment Construction

[0021] The present invention will be described in further detail below with examples in conjunction with the accompanying drawings.

[0022] combine figure 1 , the underwater cable 1 and the watertight head 3 are vulcanized and sealed, and the watertight head 3 is pressed on the end cover 2 of the airtight compartment by the backup nut 5, and an O-ring 4 is installed between the watertight head 3 and the end cover 2 of the airtight chamber to realize Face seal. Among them, the watertight head 3 is processed with a concave table at the port, and a thread is processed on the wall of the concave table to increase the contact area between the watertight head and the vulcanized rubber, which is not only beneficial to watertightness, but also beneficial to preventing the vulcanized cable from being removed from the watertight head. out.

[0023] combine figure 2 , when it is necessary to further reduce the axial size, the upper end of the watertight head can be cut off, and the...

Abstract

The invention provides an underwater propeller sealed cabin penetrating cable connector. A joint of an underwater cable and a sealed cabin penetrating cable is located in a watertight head, vulcanized rubber is arranged between the joint of the underwater cable and the sealed cabin penetrating cable and the watertight head for sealing, and the watertight head and a sealed cabin end cover are connected in a sealed mode. A pluggable structure is omitted, the radial size or the axial size of the cabin penetrating connector can be reduced, the underwater propeller sealed cabin penetrating cable connector is suitable for occasions with small mounting space such as a miniature underwater robot.

Description

technical field [0001] The present invention relates to an underwater connection and sealing structure, in particular to an underwater connector structure suitable for cables in a sealed compartment of an underwater thruster. Background technique [0002] The ocean is rich in biological resources and mineral resources. With the deepening of human development and utilization of the ocean, various underwater robots are used more and more widely. They are used to connect the sealed cabins of underwater robots and sensors, The penetrating watertight connector of the thruster and the airtight cabin is also widely used. In the existing technology, such as the watertight connector disclosed in the patent document with the application number 2009202288478.3 titled "A Watertight Connector", which consists of two parts, a plug and a socket, and can be used for the watertight connection of cables through cabins; and The patent application number is 201210117719.4 The connector disclos...
