a connector assembly

Abstract

The invention provides a connector assembly, including a plug and a socket. The jack contact of the socket is provided with an insulation fit with the jack contact and communicates with the jack and the outside of the connector assembly for connecting the plug during the plugging process. The drainage channel through which the water in the hole is discharged. The drainage channel has an opening at the inner end of the channel that communicates with the socket. The periphery of the opening at the inner end of the channel has a sealing mating surface for the drainage channel. The pin contacts of the plug are provided with an insulating seal. The member has a sealing mating surface of an insulating seal that seals and cooperates with the sealing mating surface of the drainage passage to block the opening at the inner end of the passage when the pin contact and the socket contact are located at the insertion station. When the connector assembly is in use, the water in the socket can be directly discharged out of the connector assembly through the drainage channel, which will not bring insertion resistance to the insertion end of the pin, and the insulating seal on the pin contact is also protected. The opening in the channel of the drainage channel can be closed to realize sealing and water isolation, and the utility model is very convenient to use.

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.
