A plug and connector assembly

Abstract

The present invention provides a plug and connector assembly, the plug includes a plug insulator and pin contacts extending left and right on the plug insulator, characterized in that the pin contacts are provided with insulating seals, the The insulating seal has an insulating seal sealing mating surface for sealingly cooperating with the periphery of the channel inner end opening of the drainage channel to block the channel inner end opening when the pin contact and the socket contact are located at the insertion station. When the pin contact and the socket contact are located at the insertion station, the sealing mating surface of the insulating seal can be sealed with the inner end opening of the drainage channel on the socket contact and seal the drainage channel, so that The water in the drainage channel is sealed and isolated by the insulating seal, so as to realize the sealing and isolation of the pin contacts and the water in the drainage channel, and ensure that the electrical connector can conduct electricity normally.

Description

technical field [0001] The invention relates to a conductive connection device, in particular to a plug and 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.

[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 and the conductive connection cannot be realized, and it cannot be used normally

[0004] Aiming at the technical problem in the existing technology that water accumulated in the socket affects the plug-in connection, we tried to pass a drainage channel connecting the socket and the outside of the connector on the socket contact. The drainage channel has an inner channel connected to the socket. The end is open, so that when the plug-in end of the pin contact is inserted into the socket, the water in the socket can be discharged through the drainage channel, so as to eliminate the insertion resistance, but in this way, the water in the socket can be discharged , eliminating the plugging resistance, however, since the plugged end contacts the water in the drainage channel, and the water in the drainage channel communicates with the water outside the connector, the plugged end of the pin contact is exposed to the water, completely The conductive connection of the connector cannot be achieved
