Abstract
The utility model discloses a printed circuit board with a good heat dissipation effect. The printed circuit board comprises a main body of the printed circuit board, wherein the main body of the printed wiring board is provided with an inserting hole penetrating through the upper surface and the lower surface of the circuit board, and a metal heat dissipating block is inserted in the inserting hole; the inwall of the inserting hole is provided with positioning flange extending inwards, and the metal heat dissipating block is provided with a positioning groove matching with the positioning flange. According to the printed circuit board, the metal heat dissipating block is designed to facilitate quick heat conduction and heat dissipation, thereby ensuring that the printed circuit board has a good heat dissipation effect; the positioning flange and the positioning groove are designed to facilitate the installation and positioning, thereby improving the installation efficiency; and the printed circuit board has the advantages of simple structure, low manufacturing cost, and wide application.
Description
Technical field
The utility model relates to printed wiring board, is specifically related to have the printed wiring board of great heat radiation effect.
Background technology
Usually have some high-power components and parts in the electronic products, in the course of the work, these components and parts can send great amount of heat, can this heat conducted to the other end and drain from the one of which end through printed wiring board.Existing printed wiring board generally adopts the via of array arrangement to dispel the heat, but there is the defective of radiating effect difference in this structure, therefore, need provide a kind of design of more optimizing to meet the need of market.
The utility model content
To the deficiency of prior art, the purpose of the utility model is intended to provide a kind of printed wiring board with great heat radiation effect, through adopting the design of heat dissipation metal piece, can be convenient to quick conductive and heat radiation, thereby guarantee that it has better heat radiating effect.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
Printed wiring board with great heat radiation effect comprises the printed wiring board main body, and this printed wiring board main body is provided with the inlaid hole that runs through its upper and lower surfaces, is embedded with the heat dissipation metal piece in this inlaid hole; The inwall of said inlaid hole is provided with the locating flange that extends inwardly, and the heat dissipation metal piece is provided with the detent that is complementary with locating flange.
Said locating flange is rectangular.
Said locating flange is circular arc.
The height of heat dissipation metal piece is consistent with the height of printed wiring board main body.
The printed wiring board that the utility model is set forth with great heat radiation effect, its beneficial effect is:
Through adopting the design of heat dissipation metal piece, can be convenient to quick conductive and heat radiation, thereby guarantee that it has better heat radiating effect; Through adopting the design of locating flange and detent, can be convenient to installing and locating, thereby improve its installation effectiveness; Simple in structure, cost of manufacture is low, can be convenient to be widely used.
Description of drawings
Fig. 1 is the structural representation of first kind of execution mode that the utlity model has the printed wiring board of great heat radiation effect;
Fig. 2 is the structural representation of second kind of execution mode that the utlity model has the printed wiring board of great heat radiation effect;
Wherein, 1, printed wiring board main body; 11a, locating flange; 11b, locating flange; 12, inlaid hole; 2, heat dissipation metal piece.
Embodiment
Below, in conjunction with accompanying drawing and embodiment, the printed wiring board that the utlity model has great heat radiation effect done further describing, so that clearerly understand the utility model technical thought required for protection.
As shown in Figure 1, the structural representation for first kind of execution mode of the printed wiring board that the utlity model has great heat radiation effect comprises printed wiring board main body 1.This printed wiring board main body 1 is provided with the inlaid hole 12 that runs through its upper and lower surfaces.Said inlaid hole 12 is cylindric.Also be embedded with heat dissipation metal piece 2 in this inlaid hole 12.The height of heat dissipation metal piece 2 is consistent with the height of printed wiring board main body 1.In the course of the work, the heat transferred that components and parts distribute to printed wiring board main body 1 can be transmitted heat fast and distribute through heat dissipation metal piece 2, thereby guarantees that it has better heat radiating effect.
The inwall of said inlaid hole 12 also is provided with the locating flange 11a that extends inwardly.Preferably, said locating flange 11a is rectangular.Heat dissipation metal piece 2 is provided with the detent that is complementary with locating flange 11a.Through adopting the design of locating flange 11a and detent, can be convenient to installing and locating, thereby improve its installation effectiveness.
As shown in Figure 2, be the structural representation of second kind of execution mode of the printed wiring board that the utlity model has great heat radiation effect, the difference of itself and Fig. 1 only is: locating flange 11b.Said locating flange 11b is circular arc.
To one skilled in the art, can make other various corresponding changes and deformation, and these all changes and deformation should belong within the protection range of the utility model claim all according to the technical scheme and the design of above description.
