Abstract
A waterproof power expansion board capable of disconnecting safely comprises an upper shell, a lower shell and a jack seat. At least a set of jack seat unit which is integrally connected with the upper shell by injection molding is disposed on the upper shell. Electrode conducting strips which are matched with the jack seat are disposed on the lower shell. The jack seat unit panel sinks on the surface of the upper shell to form a groove. A pressing piece is disposed in the groove and is connected with a position block through a moving pin. A connecting block, which is movably connected with a swing rod of the pressing piece through a pin shaft, above the swing rod of the pressing piece is connected with two sides of a lower end face of a support board. Jacks provided with elastic silica gel slots are reserved on the jack seat. Jacks on the support board are matched with the jacks provided with the elastic silica gel slots. The waterproof power expansion board capable of disconnecting safely is simple in structure, low in manufacture cost, labor-saving in operation and fine in safety and waterproofing, and electric shock is avoided.
Description
Technical field
The utility model relates to a kind of power extension plate, especially relates to a kind of power extension plate of the safe uncoupling that prevents to seep water.
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 socket aperture, 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, all played not the water-tight effect, can cause inner each parts of socket moist; When energized, be easy to generate short circuit and initiation fire or electric shock accidents.In the prior art simultaneously, need certain strength when pulling the plug out of the socket, because the electrode pins of plug is longer; The stingy firmly plug in place, slit that often causes people to point between plug and socket pulls out outward; When the electrode pins some was exposed at outside the socket, electrode pins also was in the circuit turn-on, and the user is as because of carelessness; Very easy contacting on the electrode pins caused electric shock accidents.
Summary of the invention
The purpose of the utility model is to existing deficiency, provides a kind of simple in structure, can also can not cause short circuit by water leaking-in in the socket aperture, and plug does not scratch drawing outward with hand, can break away from the power extension plate of connection automatically.
The utility model solves the technical scheme that its technical problem adopted: a kind of waterproof safety uncoupling power extension plate; Comprise upper shell, lower house, jack base, said upper shell and jack base unit injection mo(u)lding one; Said lower house is provided with the electrodes conduct sheet that matches with jack base, is sunken to the upper shell plane under the panel of said jack base unit and forms a groove, is provided with holding piece in the groove; Holding piece links to each other with locating piece through the pin of living; Holding piece fork top is connected with both sides, supporting plate lower surface through the contiguous block of bearing pin loose joint, and said jack base is equipped with the socket of flexible silicon colloid otch, and the jack on the supporting plate face is corresponding with the socket of flexible silicon colloid otch.
The flexible silicon colloid of said jack base socket is cylindric, and the center is the in-line otch.
Said electrodes conduct sheet is installed on the lower house Connection Block, and is connected with external wire.
Said supporting plate is ∏ shape, and supporting plate places in the groove of upper shell suitable with it.
Said holding piece one end is provided with button, and the button upper end is positioned at the upper shell outside.
The utility model jack base and upper shell injection mo(u)lding one, the in-line otch that the jack base socket becomes for the elastic silica gel system is not when plug inserts socket; Because the flexible silicon colloid is a column, otch is dark, and the otch seam fits together tightly; When inserting plug; Otch is squeezed and the electrode slice of the plug of fitting tightly, and so extraneous moisture can't penetrate into the power extension intralamellar part, has reached the purpose of waterproof.When pulling the plug out of the socket, need not to carry out drawing with hand, as long as pressing button, the holding piece interlock supporting plate of tilting upward holds up, and supporting plate ejects plug, plug electrode is broken away from connect and makes open circuit, prevents that finger from contacting the electrode slice exposed portions serve and causing electric shock.The utility model is simple in structure, low cost of manufacture, and rapid operation, safe water resistance is good, avoids the generation of electric shock accidents.

Fig. 4 is the structural representation of the utility model jack base flexible silicon colloid cut sides.
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Embodiment
Like Fig. 1,2,3, shown in 4; A kind of waterproof safety uncoupling power extension plate; Comprise upper shell 1, lower house 2, jack base 3, said upper shell and jack base unit injection mo(u)lding one are provided with one group of jack base unit at least on the upper shell 1; The present embodiment upper shell is provided with two groups of jack base unit; One group be the jack base of jack base and the neutral receptacle of line receptacle form two insert the jack base unit, the three slotting jack base unit that another group is formed for the jack base of the jack base of the jack base of line receptacle, neutral receptacle and ground receptacle, the power extension plate can design numerous jack base unit in application.The center that jack base socket 302 is processed for flexible silicon colloid 301 is provided with the in-line otch, and flexible silicon colloid 301 is cylindric, and is bonding or grip in jack base with jack base 3; Said lower house 2 is provided with the electrodes conduct sheet 7 that matches with jack base; Said electrodes conduct sheet is installed on the lower house Connection Block 6, and is connected with external wire, and said jack base unit panel is sunken to the upper shell plane for 303 times and forms a groove 302; Be provided with holding piece 4 in the groove; Holding piece links to each other with locating piece 9 through the pin 404 of living, and holding piece one end is provided with button 402, is positioned at the upper shell outside on the button; Holding piece fork 401 tops are connected with both sides, supporting plate 5 lower surface through the contiguous block 403 of bearing pin 405 loose joints; Supporting plate 5 is ∏ shape, and supporting plate 5 places in the upper shell plane groove 101 suitable with it, and the jack 501 on the supporting plate face is corresponding with the socket 302 of flexible silicon colloid otch.
