Abstract
The invention provides a water-proof and damp-proof power adapter. A primary side of a transformer of the power adapter is directly connected with a power connection piece, and then a coating device coats the transformer and a part, which is arranged in an inner cavity of a housing, of the power connection piece connected with the transformer, so that the primary side of the transformer in the inner cavity of the housing is completely coated and cannot be electrically connected, that is, no high voltage point is exposed in the inner cavity of the housing; low voltage leakage caused by a secondary side of the transformer or a circuit board happens at most even if water vapor or drops enter the inner cavity of the housing; no electric shock threat exists for a user; and the safety performance is greatly improved.
Description
Technical field
The present invention relates to power supply adaptor technical field, particularly a kind of waterproof and dampproof power supply adaptor.
Background technology
Power supply adaptor is for civil power is converted into low tension, to give the equipment of all kinds of low voltage equipment (such as computer, small household appliances etc.) power supply, charging.Because needs carry out voltage transitions, therefore need to arrange transformer.Wherein, power consumption equipment, generally from civil power power taking, is exported to after civil power being converted into low pressure again in the former limit of transformer after further rectification process.
For power supply adaptor; because all kinds of power consumption equipment of coupling uses; in some electricity consumption occasion; easy generation water inlet phenomenon, and the adapter after water inlet can leak electricity, for the power consumption equipment of low pressure; because voltage compare is low; even if electric leakage, its danger is also little, but for power supply adaptor; because its inside has transformer; the former limit of transformer is directly electrically connected with city, and its magnitude of voltage is higher, once electric leakage; its harm is relatively huge; therefore, for power supply adaptor, it is very important for carrying out waterproofing protection.At present; for waterproofing protection; common thinking strengthens further the sealing property of housing, such as, set up the assembly structure etc. of waterproof washer, improvement housing, but; because housing needs to be in communication with the outside by wire; therefore, no matter how its housing seals, and water resistance is always limited; still have steam to enter in housing when liquid to steam ratio is larger, and then cause danger of hazardous electrical discharges.
Summary of the invention
The object of the invention is to avoid above-mentioned weak point of the prior art and a kind of power supply adaptor with waterproof and dampproof function is provided.
Invention thinking: the harm considering the electric leakage of transformer mainly from former limit, applicant is in the upper discovery of original patent (ZL 200820051403.9), former limit due to transformer directly connects power connecting sheet, and power connecting sheet is through housing realization from civil power power taking, the power connecting sheet part be exposed to outside housing is directly inserted in plug, usually this part can not be intake, and in the inner casing of adapter, former limit and the power connecting sheet setting part in the housing of the just important transformer of high pressure can be had, as long as therefore by coated thoroughly for this two parts insulating material, just effectively can realize waterproof.
Object of the present invention is achieved through the following technical solutions:
Provide a kind of waterproof and dampproof power supply adaptor, comprise housing, described housing comprises inner chamber and is provided with transformer, the former limit of described transformer is connected with power connecting sheet, described power connecting sheet runs through described housing thus exposed outside housing, described housing cavity is also provided with coating unit, the former limit of the coated described transformer of described coating unit and the power connecting sheet be connected with described transformer are arranged on the part in housing cavity, thus make the former limit of transformer in housing cavity by completely coated and cannot be electrically connected.
Wherein, described housing comprises storage tank, and described transformer is positioned in described storage tank, and described power connecting sheet passes from the bottom land of described storage tank, is filled with cured resin in described storage tank, and described cured resin floods the former limit of described transformer at least completely.
Wherein, described housing comprises drain pan and top shell, and described drain pan and top shell are fixed by ultra-sonic welded.
Wherein, described power connecting sheet is made up of the integrated forward foot in a step, kink and the rear foot, and one end of kink is connected with the forward foot in a step, and the other end of kink is connected with the rear foot; Described power connecting sheet injection moulding is fixed on the bottom of drain pan, and the forward foot in a step of power connecting sheet protrudes from the lower surface of drain pan, and the rear foot of power connecting sheet protrudes from the upper surface of drain pan; The front end at the top of described transformer framework offers slot, slot internal fixtion have mate with the rear foot of power connecting sheet (3) connect electric sleeve, the rear foot of power connecting sheet inserts and connects in electric sleeve.
Wherein, be also provided with rectification circuit plate in described housing, described rectification circuit plate passes through secondary side connecting line from described transformer secondary output limit power taking.
Wherein, described cured resin floods described transformer completely, only can be powered by secondary side connecting line at housing cavity to make described transformer.
Beneficial effect of the present invention: the invention provides a kind of waterproof and dampproof power supply adaptor, the former limit of the transformer of this power supply adaptor directly connects power connecting sheet, then the coated described transformer of coating unit and the power connecting sheet that is connected with described transformer is adopted to be arranged on part in housing cavity, thus make the former limit of transformer in housing cavity by completely coated and cannot be electrically connected, that is exposed without any high pressure spot in the inner chamber of housing, even if therefore enter steam or the globule in housing cavity, the low-voltage leakage that maximum namely transformer secondary output limit or circuit board cause, there is not electric shock to user to threaten, security performance significantly improves.
Accompanying drawing explanation
The invention will be further described to utilize accompanying drawing, but the embodiment in accompanying drawing does not form any limitation of the invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, can also obtain other accompanying drawing according to the following drawings.
Fig. 1 is the structural representation of a kind of waterproof and dampproof power supply adaptor of the present invention.
Include in FIG:
1---drain pan, 2---top shell, 3---storage tank, 4---transformer, 5---rectification circuit plate.
Embodiment
The invention will be further described with the following Examples.
The embodiment of a kind of waterproof and dampproof power supply adaptor of the present invention, as shown in Figure 1, comprise housing, housing comprises drain pan 1 and top shell 2, drain pan 1 and top shell 2 are fixed by ultra-sonic welded, drain pan 1 is provided with storage tank 3, transformer 4 is placed with in storage tank 3, the former limit of transformer 4 is directly connected with power connecting sheet, power connecting sheet passes from the bottom land of described storage tank 3, cured resin (not shown) is filled with in described storage tank 3, described cured resin floods described transformer 4, make transformer 4 can be only that rectification circuit plate 5 is powered by secondary side connecting line at housing cavity.
Certainly, cured resin also can not exclusively flood transformer 4, and the former edge of only flooding transformer 4 is divided, and only needs mainly just any high pressure spot in the inner chamber of housing to be enveloped, thus prevents high pressure (220V) from leaking electricity.
