Pin contact piece and connector assembly

Abstract

The present invention provides a pin contact and a connector assembly. The pin contact comprises a plugging end, wherein the plugging end is provided with an insulation sealing element, the insulation sealing element has an insulation sealing element sealing matching surface used for being sealingly matched with a drainage channel sealing matching surface so as to block a channel inner end opening when the plugging end is in a plugging position. When the plugging end of the pin contact is in the plugging position, the insulation sealing element sealing matching surface can be sealingly matched with the drainage channel sealing matching surface on a jack contact to block a drainage channel, so that water in the drainage channel can be sealed and isolated by the insulation sealing element, and sealing and isolation between the plugging end and the water in the drainage channel can be achieved, thereby ensuring normal electric conduction of an electrical connector.

Description

technical field [0001] The invention relates to a conductive connection device, in particular to a pin contact piece 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. 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...

[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
