Description

A kind of Switching Power Supply of easy assembling

Technical field

The utility model relates to field of switch power, is specifically related to a kind of Switching Power Supply of easy assembling.

Background technology

200w Switching Power Supply is used in the electrical equipment such as Industry Control, LED display and is used widely. Switching Power Supply is made up of shell and installation circuit board and related device in the enclosure conventionally. on circuit board, be provided with interlock circuit, circuit is made up of a large amount of electronic devices and components. due to the restriction of the applied environment of Switching Power Supply, the shell sizes of Switching Power Supply is conventionally less, output voltage is relatively low, and power output is relatively large, thereby output current is relatively large, while making Switching Power Supply work, its inner meeting produces more heat, and particularly 2 output rectifying tubes are one of main heater members of Switching Power Supply. in Switching Power Supply when work, is not as accomplished efficiently radiates heat, light affect service life of Switching Power Supply, heavy may due to overheated cause Switching Power Supply internal circuit damage, therefore, effectively reduce the caloric value problem of output rectifying tube, very important for Switching Power Supply, its method to the heat radiation of 2 output rectifying tubes of common 200w Switching Power Supply is to adopt fixture 2 output rectifying tubes to be fixed on the side plate of base to carry out auxiliary heat dissipation by shell, its weak point is: 2 output rectifying tubes are installed cumbersome, affect production efficiency, extended the cabling on circuit board simultaneously, increase copper mold loss, improve Switching Power Supply cost.

Utility model content

The purpose of this utility model is: improve the mounting means of 2 output rectifying tubes, provide a kind of simple in structure, easy for installation, can be to the Switching Power Supply of the easy assembling of 2 output rectifying tube efficiently radiates heats when reducing costs and using.

The technical solution of the utility model is: the Switching Power Supply of easy assembling of the present utility model, comprise shell and circuit arrangement, and above-mentioned shell comprises base, base is made up of base plate and 2 side plate one; Circuit arrangement comprises setting circuit board in the enclosure, and circuit board is provided with circuit; The circuit of circuit board comprises 2 output rectifying tubes; Its design feature is: also comprise insulating heat-conductive pad;

The base plate of above-mentioned base is provided with a boss projecting upwards with base plate all-in-one-piece; 2 above-mentioned output rectifying tubes are arranged on the lower surface of circuit board; 2 output rectifying tubes are by the upper surface close proximity of the boss of insulating heat-conductive pad and base plate.

Further scheme is: the upper surface of above-mentioned boss is square.

Further scheme is: 2 above-mentioned output rectifying tubes are metal-oxide-semiconductor.

Further scheme is: the material of above-mentioned shell is aluminium.

The utlity model has positive effect: the Switching Power Supply of easy assembling of the present utility model, it by arranging a boss projecting upwards with base plate all-in-one-piece on the base plate of outer casing base, 2 output rectifying tubes are arranged on the lower surface of circuit board, 2 output rectifying tubes are by insulating heat-conductive pad and boss close contact, its advantage is easy for installation firm in process of production on the one hand, has improved production efficiency; Shorten on the other hand the cabling on circuit board, by low copper mold loss, thereby reduced Switching Power Supply cost; The heat that while work, 2 output rectifying tubes produce simultaneously can be directly delivered on base, participates in heat radiation directly by shell, has strengthened the radiating effect of Switching Power Supply.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

(embodiment 1)

See Fig. 1 to Fig. 5, the Switching Power Supply of the easy assembling of the present embodiment, it is mainly made up of shell 1, circuit arrangement and insulating heat-conductive pad 4.

Referring to Fig. 2, Fig. 3 and Fig. 5, shell 1 is mainly made up of base 11 and upper cover 12. Base 11 is made up of base plate 11-1 and 2 side plate 11-2 one, and 2 side plate 11-2 are each respectively in the upper end, the left and right sides of base plate 11-1 arranges 1; The base plate 11-1 of base 11 is provided with a boss 11-1-1 who projects upwards with base plate 11-1 all-in-one-piece, and the upper surface of boss 11-1-1 is square substantially. While installing, upper cover 12 is fastened on the upper end of base 11 and is screwed and connects the common shell 1 that forms. The material of shell 1 is the aluminium easily dispelling the heat.
