Connector assembly

Abstract

The invention provides a connector assembly comprising a plug and a socket. The jack contact members of the socket are provided with water drainage channels which are matched with the jack contact members in an insulating way and enable jacks and the external part of the connector assembly to be communicated so as to drain out water in the jacks in the plugging process. The water drainage channels are provided with channel internal end openings which are communicated with the jacks. The periphery of the channel internal end openings is provided with water drainage channel sealing matching surfaces. The pin contact members of the plug are provided with insulating sealing members which are provided with insulating sealing member sealing matching surfaces which are matched with the water drainage channel sealing matching surfaces in a sealing way so as to plug the channel internal end openings when the pin contact members and the jack contact members are positioned at the plugging position. When the connector assembly is used, water in the jacks can be directly drained out of the connector assembly via the water drainage channels without bringing plugging resistance to the plugging ends of the pins, and the channel internal openings of the water drainage channels can also be sealed by the insulating sealing members on the pin contact members so as to realize sealing and water insulation and thus use is quite convenient.

Description

technical field [0001] The invention relates to a conductive connection device, in particular to a connector assembly. Background technique [0002] With the development of submarine power transmission, the application of underwater connectors is becoming more and more extensive, and its role is becoming more and more important. The main technical problem of the underwater electrical connector is how to ensure the conductive seal, especially the problem of ensuring that there will be no water accumulation between the plug and the socket during the insertion process. [0003] The Chinese invention patent with the publication number CN101106230A and the announcement date of January 16, 2008 discloses a plug-in sealing structure for underwater electrical connector contacts. A drainage groove is set between the insulating sleeve on the top and the socket insulator, that is, the mating surface on the socket insulator to achieve the purpose of draining the water between the two w...

[0003] The Chinese invention patent with the publication number CN101106230A and the announcement date of January 16, 2008 discloses a plug-in sealing structure for underwater electrical connector contacts. A drainage groove is set between the insulating sleeve on the top and the socket insulator, that is, the mating surface on the socket insulator to achieve the purpose of draining the water between the two when the plug and socket are inserted, although such a mating sealing structure can Drain the accumulated water between the plug and the socket, but there is no way to discharge the water that enters the socket socket contact before insertion, so that the water in the socket contact occupies a certain insertion space, resulting in resistance to insertion Very large, it is difficult to insert into the insertion position, that is, the insertion end of the pin contact is located at the bottom of the socket of the socket contact, which seriously affects the use of the connector, and the forced insertion will easily cause the pin The plug-in end of the contact or the socket of the socket contact is damaged and deformed, and even the seal fails to realize the conductive connection and cannot be used normally. In addition, the plug-in sealing structure also passes through the circumference of the insulating sleeve and the socket insulator. A sealing ring is set at the matching position to prevent external water from entering the circumferential mating surface of the pin contact and the socket contact. This method has a complex structure and high production costs.
