Abstract

The utility model discloses an industrial power supply which comprises a circuit board. A transformer, a triode and a rectifier are electrically connected on the circuit board, wherein the transformer is placed in the middle of the circuit board, the triode is positioned on the circuit board close to one side of the transformer, and the rectifier is positioned on the circuit board close to the other side of the transformer. The triode and the rectifier are respectively arranged reversely, and accommodation spaces are respectively left below the triode and the rectifier. According to the industrial power supply of the utility model, the triode and the rectifier are respectively arranged reversely to leave installation spaces for electronic elements thereof, thereby being helpful for miniaturization of products.

Description

A kind of industrial power

Technical field

The utility model relates to a kind of industrial power, relates in particular to a kind of power supply of slimming design.

Background technology

Flourish along with the progress of electronics technology and industry, the external form of various industrial electronics be all towards short and small frivolous trend development, along with this development trend, the volume of power supply used also required to develop to ultra-thin, miniaturization.

Traditional industrial products power supply external form is cuboid, inside is provided with the electronic building bricks such as circuit board, electric capacity, transistor,, in order to reduce its volume, normally adopts the thickness reduce of each assembly, whole shortening yet on length and width, also caused a large amount of gatherings of heat simultaneously.

Summary of the invention

For the defect of prior art, the utility model discloses the industrial power of a kind of slimming design, each assembly layout again is located on circuit board,, with the area that dwindles circuit board and the volume of power supply, reduce the placement space while using.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind of industrial power, comprise circuit board, be electrically connected with transformer, triode and rectifier on circuit board, transformer is positioned in the middle of circuit board, triode is positioned at a side of next-door neighbour's transformer on circuit board, and rectifier is positioned at the opposite side of next-door neighbour's transformer on circuit board, wherein, triode and rectifier are inverted, and accommodation space is left in its below.

By rectifier and triode parallel longitudinal being arranged on the both sides of transformer, thereby and rectifier, triode are inverted and other electron component can be arranged in the space of below, shortened circuit board length and width, thereby dwindled power volume.

In order to reduce the thickness of power supply, described circuit board central authorities have the perforation that runs through, and are used for settling described transformer.

For the industrial power that guarantees slimming design still has good heat dispersion, the utility model is optimized design to the heat radiation of each parts wherein, and the structure of employing is as follows:

(1) be fitted with fin on described transformer;

(2) be covered with the first thin conducting strip on described triode, the first thin conducting strip laminating fin;

(3) described rectifier is covered with the second thin conducting strip, the second thin conducting strip laminating fin.

By above-mentioned design, the heat that the transformer on circuit board, triode and rectifier produce, pass to fin by conducting strip, by the fin conductive loss.

In the utility model, described rectifier is preferably diode, the rectifier of other types be also can be used for of the present utility model.

In the utility model, each component packages in power supply in same housing, realizes that volume minimizes.

Improve by said structure, industrial power of the present utility model has been achieved compact conformation, the volume optimization that minimizes, dispels the heat.

Description of drawings

Fig. 2 is industrial power finished figure of the present utility model.

Embodiment

With reference to accompanying drawing 1, industrial power of the present utility model, comprise circuit board 10, fin 20, the second fin 30 (further improving radiating efficiency) and housing 40, and the integrated circuit construction packages is in housing 40.

Wherein, circuit board 10 is microscler lamellar body, and its central part has perforation 101, and transformer 11 is arranged in perforation, and transformer 11 is electrically connected to circuit board 10.

Be electrically connected with the assemblies such as triode 12, rectifier 13 and filter capacitor 14 on circuit board 10, circuit board 10 1 ends are provided with socket 15 (being used for connecing external loading), and the other end connects wire 16 (external power input); Triode 12 is inverted, and is positioned at a side of next-door neighbour's transformer 10 on circuit board 10, because triode 12 is inverted, thereunder leaves accommodation space 120, and accommodation space 120 can arrange a plurality of electronic components 121 for installing, and saves the space on circuit board 10; It is the U font that triode 12 has amplexiformed the first thin conducting strip 122 of thin conducting strip 122, the first, the heat that produces while being used for conducting triode 12 work.

Rectifier 13 is diode, parallel with triode 12, be arranged at the opposite side of next-door neighbour's transformer 11 on circuit board 10, namely both lay respectively at left and right two sides, the second thin conducting strip 131 has been amplexiformed in the top of rectifier 13, the heat of the second thin conducting strip 131 conduction rectifiers 13, rectifier 13 is inverted, and the below accommodation space can arrange a plurality of electronic components 132 for installing.

Wherein, fin 20 covers at circuit board 10 1 sides, amplexiforms transformer 11 assemblies such as grade, to derive the heat that is produced.

Wherein, housing 40 comprises upper casing 40a, lower casing 40b, and both all circuit unit inclusions are entered in combination, and the second fin 30 fits tightly at lower casing 40b, so that the heat of order wire circuit plate reverse side.
