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
the present invention relates to conductive connecting device, particularly relate to a kind of contact pin contacting piece and connector assembly.
Background technology
Along with the development of subsea power conveying, the application of underwater connector is more and more extensive, and its effect played is also more and more important.The main difficult technical of underwater electrical connector is how to ensure conductive seal, especially puts into grafting process at plug and socket and ensures can not amass water problem between the two.
Publication number is CN101106230A, the day for announcing is that the Chinese invention patent on January 16th, 2008 discloses a kind of plug sealing structure of underwater electrical connector contact part, this connector plugs together hermetically-sealed construction by arranging rhone between the mating surface on insulating sleeve on contact pin insulator and pin insulator and jack insulator and socket insulator to reach the object of being discharged by water between the two when plug and socket grafting, the hermetically-sealed construction that plugs together although it is so can by the ponding discharge between plug and socket, but but have no idea to discharge at the water advanced in receptacle sockets contact of grafting, like this because the water in jack contact occupies certain grafting space, cause slotting resistance very large, the inserted terminal being difficult to be plugged into grafting station and contact pin contacting piece is positioned at bottom the jack of jack contact, have a strong impact on the use of connector, and mandatory grafting can be easy to cause the inserted terminal of contact pin contacting piece or the jack of jack contact to damage distortion, even cause seal failure and conduction connection can not be realized, cannot normally use.
The technical problem that water affects grafting is contained in the jack that prior art exists, we attempt on jack contact, wear the drainage channel be communicated with outside jack and connector, drainage channel has end opening in the passage that is communicated with jack, to realize when the inserted terminal of contact pin contacting piece inserts in jack, water in jack can be discharged by drainage channel, reach the object eliminating grafting resistance, although but like this water in jack is discharged, eliminate grafting resistance, but contact with each other due to the water in inserted terminal and drainage channel, water in drainage channel again with the water intercommunication outside connector, the inserted terminal of such contact pin contacting piece is just exposed in water, the conduction that can not realize connector completely connects.
Summary of the invention
The object of the present invention is to provide a kind of when grafting station place by the contact pin contacting piece of drainage channel and inserted terminal seal isolation; Meanwhile, present invention also offers a kind of connector assembly using this contact pin contacting piece.
In order to solve the problems of the technologies described above, contact pin contacting piece of the present invention adopts following technical scheme: a kind of contact pin contacting piece, comprise inserted terminal, described inserted terminal is provided with insulating sealer, and described insulating sealer has and to be sealed and matched face with the insulating sealer of shutoff passage end opening for being sealed and matched with the drainage channel face of being sealed and matched when inserted terminal is positioned at grafting station place.
