Description
Technical field
The present invention relates to electrical equipment technical field, more particularly to electric connector, more particularly to a kind of water-proof circular is electrically connected
Connect device.
Background technology
Electric connector is mainly to apply to be electrically connected between device and device, component and component, system and system
It is to constitute base components necessary to a completion system with signal transmission.Electric connector in correlation technique is by fixing end electricity
Connector, i.e. female contact (abbreviation socket), and free-end electric connector, i.e. male contact (abbreviation plug) are constituted.Socket leads to
Cross its side (circle) disk to be fixed in consuming parts and (also use welding manner individually), plug typically connects cable, then inserts by plug
Enter and circuit communication is realized into socket.
At present, round electric connector is widely used in underwater electrical equipment, or applied in wet environment, to its waterproof
Property (i.e. sealing) has very high requirement.In the prior art, the sealing between plug and socket is typically employed in plug or inserted
Sealing ring is set to improve on the cylindrical outer wall or inwall of seat.But, when socket and plug is separated, inner walls and sealing
The distance rubbed between circle, easily occurs getting rid of gas phenomenon, causes the plug of electric connector difficult, and fragile sealing ring, causes
Seal failure.In addition, the electric connector of most of existing fast insert-pulls will be by rotating or to the opposite side of plug orientation
To outside sliding sleeve is pulled, the Plug Action between tap and socket could be completed, plug is more inconvenient.
Therefore, how structure improvement is carried out to existing electric connector, improves its sealing and convenient plug, be this area
Technical staff's problem urgently to be resolved hurrily.
The content of the invention
It is a primary object of the present invention to provide a kind of plug fast and easy, and service life is long, simple and reasonable
