Abstract
The utility model provides a waterproof plug which comprises a plug body, wherein, the plug body is provided with a sealing piece; and the bottom face of the sealing piece is matched and connected with the end face of the plug body into a whole body. Because the plug body is provided with the sealing piece; the bottom face of the sealing piece is fixedly connected with the end face of the plug body; when the plug body is inserted into a socket, the sealing piece coats the circumference of a socket hole to completely seal pins on the plug body, then the purpose of preventing water from flowing into the inner part of the socket is achieved, the security of the plug is enhanced, and the sealing piece can play a better role of sealing when rain water is more.
Description
Technical field
The utility model product relates to a kind of plug, relates in particular to a kind of waterproof plug, belongs to the technical field of arrangements of electric connection.
Background technology
The plug overwhelming majority in afforestation is directly exposed to outdoor, needs better waterproof and fail safe.Traditional attaching plug does not have seal, when plug cooperates with socket, the crack is bigger between the two, sealing property is bad, grown in the outdoor exposure time, be easy in socket aperture inflow socket or because of making moist, cause short circuit, thereby cause device damage or personnel's electric shock accidents because of the water in the external world, very dangerous.
Recently, a kind of waterproof plug has appearred on the market, comprise header body, be located at the pin on the header body, wherein, be fixed with a sealing ring, the waterproof plug of this structure on the bayonet cap around the described corresponding pin, though can seal plug to a certain extent, play waterproof effect, but grown service time, sealing was lost efficacy easily, useful life is not long, if in rainy season, rainwater flows in the socket aperture by bayonet cap easily, also influences pin and causes electric leakage because of bayonet cap makes moist easily, use not too safe, in addition, because each pin all need be loaded onto independently sealing ring, processing is got up cumbersome.
The content of utility model
Technical problem to be solved in the utility model provides that a kind of sealing property is strong, fail safe good, waterproof plug simple in structure and easy to process.
In order to solve the problems of the technologies described above, a kind of waterproof plug of the utility model comprises header body, and wherein, described header body is provided with a seal, matches with the end face of described header body and link into an integrated entity in the bottom surface of described seal.
Above-mentioned a kind of waterproof plug, wherein, described seal is bowl-type.
Adopt the waterproof plug of said structure, because described header body is provided with a seal, fixedly connected with the end face of described header body in the bottom surface of described seal, when header body was inserted socket, described seal was coated on around the socket aperture, in the pin on the header body is sealed in fully, prevent that water from flowing into the purpose of socket inside thereby reach, improved the fail safe of plug, particularly worked as rainwater more for a long time, the sealing part can play the better seal effect; In addition, because seal is a bowl-type, process more convenient and simple in structure.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
In order to solve the problems of the technologies described above, a kind of waterproof plug of the utility model, comprise header body 1, described header body 1 is provided with a seal 2, match with the end face of described header body 1 and link into an integrated entity in the bottom surface of described seal 2, described seal 2 is unrestricted with the position that described header body 1 matches, the front end face or the rear end face of the bottom surface of described seal 2 and described header body 1 are sealed and matched, also described seal 2 can be coated on the front end outer surface of described header body 1, also can be positioned at the back end outer surface of described header body 1, in order to save cost, easy to process, in the present embodiment, the bottom surface of described seal 2 and the end face of described header body 1 front end can also be fixed into one, described header body 1 is provided with pin 11, described seal 2 is unrestricted, can be hollow cylinder, also can be other shapes, for easy to process, simple in structure, in the present embodiment, described seal 2 is a bowl-type, the bottom surface of described bowl-type seal is provided with the hole, described pin 11 passes described hole, thereby described bowl-type seal and described header body 1 are fixed into one, described seal 2 also can adopt the method for press forming, be made of one with described header body 1, described header body 1 is unrestricted, can be Single-phase plug, the two-phase plug also can be 3-phase plug, owing to be provided with a seal 2 at the end face of described header body 1, and when header body 1 is inserted socket, in described seal 2 is coated on the surface around the socket aperture, in pin on the header body 1 is coated on fully, prevent that water from flowing into the purpose of socket inside, the fail safe that has improved plug thereby reach, particularly work as rainwater more for a long time, sealing part 2 can play the better seal effect.
Compare with existing unprotect measure, the utility model has been owing to set up seal in the header body periphery, therefore can be in use with plug with closely be connected by plug-and-socket, reach obturation effect, thereby reach the purpose of waterproof.
Here description of the present utility model and application are illustrative; be not to want in the above-described embodiments with scope restriction of the present utility model; therefore, the utility model is not subjected to the restriction of present embodiment, and the technical scheme that any employing equivalence replacement obtains is all in the scope of the utility model protection.
