Embodiment Construction

[0015] An embodiment of an underwater plug connector, such as Figure 1-2 As shown: the underwater connector in this embodiment includes a housing 1 and a contact piece. In this embodiment, the contact piece 5 has a crown spring belt. The housing has a plugging channel extending forward and backward. The insertion port 3 at the front end of the passage is used for inserting the contact piece of the adapter connector into the insertion passage. The insertion passage is provided with a water chamber 9 for communicating with the water body outside the shell. The hole sealing rod 4, the front end of the jack sealing rod has a mating end face for pushing and matching with the crown spring band 5, and the rear of the insertion port in the insertion channel is provided with a front rod section and an insertion hole for the jack sealing rod. The crown spring has a sealing structure with a sliding seal. Between the sealing structure and the water chamber, there is an oil-filled chamber...

Abstract

The invention discloses an underwater wet-mate connector. A casing is provided with a plugging passage which extends forwards and backwards, the casing is provided with an inserting opening which is positioned at the front end of the plugging passage and is used for enabling a contact part of an adaptive connector to be inserted into the plugging passage, a water through cavity is arranged in the plugging passage and is communicated with a water body outside the casing, an inserting hole sealing rod is arranged in the plugging passage along the front and back direction in a guiding and moving way, the front end of the inserting hole sealing rod is provided with a matching end surface which is in pushing matching with the contact part of the adapting connector, the interior of the plugging passage is provided with a sealing structure behind the inserting opening, an oil filling cavity is arranged between the sealing structure and the water through cavity in the plugging passage, a piston block which is used for separating the oil filling cavity from the water through cavity is arranged in the plugging passage in a sliding and sealing way, the back part of the inserting hole sealing rod and the contact part are respectively arranged in the oil filling cavity, the back end of the inserting hole sealing rod is in driving connection with the piston block through an elastic part, and a floating block is connected with a reset spring. The underwater wet-mate connector effectively solves the problem of unreliable sealing of the existing underwater wet-mate connector.

Description

technical field [0001] The invention relates to the technical field of structural design and application of signal transmission connectors, and in particular provides an underwater plug-in connector applicable to deep water environments such as seabeds. Background technique [0002] At present, in the field of electrical connectors, electrical connectors with underwater plugging and unplugging functions require that each contact should be isolated after the product is mated in a deep water environment to avoid short circuits. The water pressure will cause the connector to leak and affect the normal use. [0003] The Chinese patent No. 201310369867.X discloses a connector for underwater plugging. The connector includes an insulating housing, a socket sealing rod and an electrical contact. Channel, the front end of the plug-in channel is provided with an insertion port extending from front to rear for the insertion of the socket sealing rod, and a water passage chamber is pro...
