Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] The split watertight connector of the present invention includes a socket and a plug. One end of the socket is installed on the sealing cabin of the underwater operation equipment. The plug has multiple petals, which are respectively inserted into the other end of the socket according to the partition to achieve the effect of axial sealing. The socket and the plug are connected to the external thread of the external thread lock nut of the plug through the internal thread of the internal thread lock nut to prevent loosening.

[0033] Such as Figure 5 , Figure 6 As shown, the plug includes an external thread locking nut 27 and a second rubber vulcanization sealing body 23 accommodated in the external thread locking nut 27 with multiple petals (six petals in this embodiment), and the second rubber vulcanization of each petal One end of the sealing bod...

Abstract

The invention belongs to the field of an underwater connector, and particularly relates to a segmental watertight connector. The segmental watertight connector is mounted on underwater operation equipment. A socket has a housing, a jack and a guiding hole, wherein the jack and the guiding hole are in a first rubber sulfuration sealing member. One end of the jack is connected with a lead, and the other end is provided with an independent inner chamber. An annular projection exists in the inner chamber. A plug is provided with a plurality of second rubber sulfuration sealing members. Each secondrubber sulfuration sealing member is provided with a pin and a guiding pin. Furthermore the bottom of each pin is provided with an independent rubber insulating rod. One end of the pin is connected with a lead in a cable, and the other end is inserted into the jack. The rubber insulating rod is inserted into the inner chamber and abuts against an annular projection in a sealed manner. The socketand the corresponding plug according to the invention can be plugged in a wet environment and can be used in shallow sea and deep sea and furthermore have reliable sealing performance. The socket andthe corresponding plug are suitable for electric signal transmission in various kinds of underwater operation equipment. Furthermore connection of a plurality of plugs with cables with the equipment through one socket can be realized.

Description

technical field [0001] The invention belongs to the field of underwater connectors, in particular to a split watertight connector used in underwater operations to transmit electrical signals. Background technique [0002] With the development of weapons and the art of war, the sea has greater military application value. Now the defense on land is almost exposed, only the vast and majestic ocean still leaves hidden positions for sudden attacks and potential defenses. Watertight connectors are one of the indispensable and important coastal defense equipment. The existing watertight connectors have the following problems: [0003] 1. With the increasing complexity and diversity of underwater instruments and equipment, and the improvement of the degree of integration, the final integration of multiple signals and power into one terminal has become a key node for many marine equipment. The traditional way is to use all-in-one or one-point-multiple watertight junction boxes, whi...
