Description
Technical field
The utility model relates to the connector of electric wiring, particularly a kind of waterproof plug and socket.
Background technology
Present electronic product is such as the picture transformer, Switching Power Supply etc., output connects with generally all adopting earphone jack being connected of load, though the fairly simple convenience of method of attachment, its shortcoming is, the electric current contact-making surface is little, if the load current that connects is bigger, plug just is easy to heating, distortion, even burn, such as being connected of powerful Colour lamp for fastival and holiday and power supply.What also have is easy to oxidation in a humid environment and causes loose contact because be to use, the use that also has is on automobile, or the gang socket on the electric bicycle, because long-term vibration or pulling force are easy to cause loose contact or come off inadequately, bring a lot of troubles to use.
Summary of the invention
At above-mentioned technical problem, the purpose of this utility model provides a kind of waterproof plug and socket, and plug is with after socket is connected, not only can moistureproof, waterproof, and connect fasteningly, can bear big pulling force.
The purpose of this utility model is achieved through the following technical solutions:
Waterproof plug and socket, described plug comprises insulator and at least two conductive base pins, conductive base pin is fixed on the end face of insulator, socket comprises insulating base and at least two conductive jacks for the conductive base pin insertion, conductive jack is arranged on the end face of insulating base, and described plug comprises that also one has the waterproof nut of internal thread, and this waterproof spiro cap is on insulator, described insulating base surface is provided with the waterproof screw thread, and the waterproof nut is threaded with the waterproof screw thread.
Described waterproof nut one end is provided with limiting section, and this limiting section is provided with through hole.
Described insulator is provided with limited step.
The conductive base pin of described plug is the conductive base pin of taper, and the conductive jack of described socket is the conductive jack of taper.
Described conductive base pin one end is provided with the conducting strip that connects lead, and the conductive jack end is provided with the conducting strip that connects lead.
Adopted such scheme, plug comprises that also one has the waterproof nut of internal thread, and this waterproof spiro cap is on insulator, and described insulating base surface is provided with the waterproof screw thread, and the waterproof nut is threaded with the waterproof screw thread.When plug with after socket is connected, combine with the waterproof screw thread by the waterproof nut, make plug and socket be arranged in the space of sealing, can prevent that like this plug and socket from touching the damp-proof air of water, avoid conductive base pin and conductive jack to be subjected to oxidation, can prolong the useful life of conductive base pin and conductive jack; In use, make plug and socket bear bigger widening, and can resist vibrations and conductive base pin and conductive jack are not come off.
The conductive base pin of plug is the conductive base pin of taper, and the conductive jack of socket is the conductive jack of taper.When plug with after socket is connected, can increase the contact area of conductive base pin and conductive jack, not only provide condition, and reduced contact resistance, made conductive base pin and conductive jack enough contact-making surfaces be arranged by big electric current for conductive base pin and conductive jack form to closely cooperate.
The utility model is except that having above-mentioned advantage, and is simple in structure in addition, safe, and advantage easy to use.
Below in conjunction with the drawings and specific embodiments the utility model is done an into explanation.
