Abstract
The utility model provides a rotation type water-proof power supply expansion board with a water leakage structure. The rotation type water-proof power supply expansion board comprises a housing and a socket unit, wherein at least one hole for installing the socket unit is arranged in a panel of the housing, the side walls of the hole are respectively provided with a ring-shaped step, cover plates of the socket unit are embedded into the ring-shaped steps matched with the cover plates, one sides of the holes of the housing are provided with slide ways adjacent to the holes, stop plates extending from one sides of the cover plates of the sliding socket unit are adhered to the slide ways in a sliding way, an electricity-conducting wafer in a jack of the socket unit penetrates through the wall of the socket and is formed with the socket unit into a whole in an injection way, a lower opening of the jack is provided with a mesh hole, and the periphery of the insert opening of the jack is provided with upwards convex lug bosses. The rotation type water-proof power supply expansion board prevents external moisture from permeating into the socket, and the electricity-conducting wafer in the jack can not be directly contacted with an electrode conducting strip at the inner chamber of the housing, so that the rotation type water-proof power supply expansion board has the functions of water resistance and electric shock resistance, and has advantages of being simple in structure, low in manufacture cost, and good in safety performance.
Description
Technical field
The utility model relates to a kind of power extension plate, especially relates to a kind of rotary waterproof power extension plate that has water-leaking structure.
Background technology
The power extension plate is the electric equipment products that are used for realizing through the insertion of external plug electrical connection in the daily life, and in use, people run into the environment that water is arranged through regular meeting, or because of carelessness water is sprinkled to the power extension plate the generation that causes the accident.So; The technical staff has developed the power extension plate with water-proof function; These waterproof power extension plates are equipped with waterproof cover outside socket, anti-sealing penetrates in the power extension plate, and some power extension plate is provided with sealing ring outside socket aperture; In the time of in the plug insertion socket hole, make between plug and the socket and play sealing function.In existing these technology; Can't really reach the effect of waterproof, if do not build waterproof cover, or plug and socket contact-making surface imprecision; Water resistance has played not effect; The capital causes inner each parts of expansion board moist, when energized, is easy to generate short circuit and initiation fire or electric shock accidents.
Summary of the invention
The purpose of the utility model is to existing deficiency, provides a kind of simple in structure, prevents to get an electric shock, and also can not cause a kind of rotary waterproof power extension plate that has water-leaking structure of short circuit in the socket aperture behind the water leaking-in.
The utility model solves the technical scheme that its technical problem adopted: a kind of rotary waterproof power extension plate that has water-leaking structure; Comprise housing, socket unit; The panel of said housing is provided with at least one hole that is used for the mounting receptacle unit; The hole sidewall is provided with annular table circle, and the cover plate of said socket unit embeds on annular table circle suitable with it, and hole one side of said housing is provided with the chute adjacent to hole; Post the baffle plate of the socket unit cover plate one side extension of sliding on the chute mutually; Conductive contact blade passes socket wall and annotates the synthesis type one with socket unit in the socket unit jack, and the jack end opening is provided with mesh, and jack is provided with the boss that projects upwards around inserting mouth.
Said conductive contact blade touches with the electrodes conduct sheet on rotation mode and the housing inner chamber connector and closes.
Said socket unit and bottom joint are provided with sealing ring.
Said socket unit is two plug-and-sockets or three plug-and-sockets.
Conductive contact blade and socket unit injection mo(u)lding one in the utility model jack; Completely cut off extraneous moisture to the inner infiltration of socket; The water that gets in the jack is discharged outside the housing from the end opening mesh of jack; There is not knot water phenomenon in the jack, can not make power supply cause short circuit because of the immersion of water, played waterproof action.Conductive contact blade in the jack does not directly contact with the electrodes conduct sheet of housing inner chamber, and conductive contact blade is not charged in the jack, can not cause electric shock accidents even foreign matter inserts in the jack yet; After having only plug to insert conductive contact blade; The Rotating socket unit makes conductive contact blade touch mutually with the electrodes conduct sheet and closes, and just makes current lead-through; Improve the security performance of socket, prevented the generation of electric shock accidents.The utility model advantage: simple in structure, low cost of manufacture, safe water resistance is good.
Description of drawings
