Description
Technical field
The utility model relates to a kind of power supply, relates in particular to a kind of Novel DC Switching Power Supply.
Background technology
Along with the raising of industrial production technology and the expansion in military, civilian market, a lot of products very commonly used are by original integrated trends of design modularization, commercialization production.In recent years, particularly outstanding in the performance of high speed fast development electric power, electron trade.One of them example is exactly that exchange to change the commercialization of direct-current switch power supply of common occurrence in actual life.220V on the market (AC) changes 110V (DC), 48V (DC), 24V (DC), 12V (DC), 5V (DC) or the like product and brings greatly facility for social demand more and more widely.
Most in the market Switching Power Supply is the design of hollow out metal shell, and its advantage is following: 1) protection internal circuit board device prevents situation such as fall and causes inner precision components to be damaged; 2) the hollow out mode makes heater element directly contact with air, is beneficial to heat radiation.But existing hollow out metal-back is known from experience and is brought some negative influences, and for example: 1) Wiring port exposes, and operator such as careless use as easy as rolling off a logly cause short circuit.2) though designing, the hollow out mode is beneficial to heat radiation, but non-watertight, and in a single day electronic circuit meets water, is easy to be short-circuited, quite dangerous, this kind design has limited the range of application of product to a certain extent.3) the hollow out mode is not dustproof, if contain the micronic dust long-term accumulation of electric conductivity particle, can cause short circuit yet.
Though three anti-Switching Power Supplies (waterproof and dustproof, anti-beating) are arranged on the market, complex structure, price is also quite expensive, therefore, is necessary to provide the Novel DC Switching Power Supply.
The utility model content
The utility model technical problem to be solved provides a kind of Novel DC Switching Power Supply, can waterproof and dustproof, shatter-resistant, and simple in structure.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to provide a kind of Novel DC Switching Power Supply, comprises the power supply body, wherein; Said power supply body is placed in the metal shell; Said metal shell comprises drain pan, cover cap and two end cover plate, and said power supply body-fixed is on drain pan, and said power supply body and drain pan contact-making surface are coated with the thermal conductive silicon glue-line; Perforate extracting power supply cord on one end casing, said tapping is provided with water joint.
Above-mentioned Novel DC Switching Power Supply wherein, is provided with waterproof washer between said two end cover plate and cover cap and the drain pan.
Above-mentioned Novel DC Switching Power Supply wherein, is provided with the waterproof bar in the slot of said drain pan and cover cap.
Above-mentioned Novel DC Switching Power Supply, wherein, the metal shell that said drain pan, cover cap and two end cover plate are formed is the aluminium section bar housing.
The utility model contrast prior art has following beneficial effect: the Novel DC Switching Power Supply that the utility model provides; The power supply body is placed in the metal shell and perforate extracting power supply cord on the cover plate at one end; And be provided with water joint at tapping; Thereby it is have waterproof and dustproof, shatter-resistant function, and simple in structure.
Description of drawings
Fig. 1 is the utility model direct-current switch power supply structural representation.
Among the figure:
1 drain pan, 2 cover caps, 3 cover plates
4 power supply bodies, 5 water joints
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe.
Fig. 1 is the utility model direct-current switch power supply structural representation.
See also Fig. 1, the Novel DC Switching Power Supply that the utility model provides comprises power supply body 4, wherein; Said power supply body 4 is placed in the metal shell; Said metal shell comprises drain pan 1, cover cap 2 and two end cover plate 3, and said power supply body 4 is fixed on the drain pan 1, and said power supply body 4 is coated with the thermal conductive silicon glue-line with drain pan 1 contact-making surface; Perforate extracting power supply cord on one end casing, said tapping is provided with water joint 5.
Above-mentioned Novel DC Switching Power Supply; The metal shell that said drain pan 1, cover cap 2 and two end cover plate 3 are formed is preferably the aluminium section bar housing; This kind housing quality is slim and graceful, erection method is simple and direct, thermal conductivity is higher, waterproof and dustproof, the anti-performance of beating are good; And because streamline production, price is very cheap.
In order further to strengthen water-proof function, be provided with waterproof washer between two end cover plate 3 and cover cap 2 and the drain pan 1; Be provided with the waterproof bar in the slot of said drain pan 1 and cover cap 2.
In sum, the Novel DC Switching Power Supply that the utility model provides fixedly is placed on power supply body 4 on the housing drain pan 1 with the metal screw; Give the wherein cover plate 3 installation water joints 5 of an end; And interspersed 220V 3-phase plug and DC leadout, and wire harness is installed to the corresponding port of Switching Power Supply (noticing that the 3-phase plug ground wire must be correct), the output of dc output power both positive and negative polarity must mark clear at leading-out terminal in addition; Usually represent anodal output with red line in the industry, black line is represented negative pole output; Cover cover cap 2, and, fully Switching Power Supply is enclosed in waterproof and dustproof, the anti-aluminium section bar housing of beating with the fixing tight two end cover plate 3 of metal screw.
Though the utility model discloses as above with preferred embodiment; Right its is not in order to limit the utility model; Any those skilled in the art; In spirit that does not break away from the utility model and scope, when can doing a little modification and perfect, so the protection range of the utility model is when being as the criterion with what claims defined.
