Described support portion and fixed part one-body molded.
Described circuit board is provided with through hole, and one end of described support portion is adsorbed on described metal chassis through after described through hole, and the flange of described fixed part is against the surface of described circuit board.
Described magnetic is along surrounding's arrangement of described circuit board, and the support portion of described magnetic is adsorbed on described metal chassis, and described fixed part is stuck in the edge of described circuit board.
The surface configuration of the fixed part of described magnetic is circular, ellipse, triangle or polygon.
The beneficial effects of the utility model are:
1. compared with prior art, the utility model adopts magnetic-type fixing means, can make installation and easy to maintenanceization.The utility model is mainly used in LED illumination lamp, particularly with the lighting (as products such as lamp affixed to the ceilings) of iron metal chassis, be characterized in can easily the circuit board magnet adsorption with light source on metal chassis, and circuit board is without the need to installing any holding screw additional, the assembly fee saving product is greatly used.Without any need for fastening screw when the installation of circuit board and metal chassis is fixed, certainly also without any need for being the supporting attachment device of holding screw, therefore, not only saving the material cost of product, also greatly saving packaging volume and the freight of product.
2. on this basis, the utility model is except being firmly adsorbed on circuit board except on iron metal chassis, circuit board and metal chassis close contact can be made, for the circuit board with LED light source, certain heat can be sent due to when LED light source work, if these heats do not dissipate in time, the service life of LED can be affected, circuit board and metal chassis close contact can make the heat on circuit board outwards be distributed fast by metal chassis effectively, reach good radiating effect, increase the service life.
3. the surface configuration of the fixed part of magnetic of the present utility model can make any shape (such as circular, oval, triangle or polygon etc.) as required, is convenient to supporting the use under various condition.

Detailed description of the invention
Referring to figs. 1 through Fig. 7, the fixed structure of a kind of circuit board and metal chassis, comprises metal chassis 2 and circuit board 1, and be that described metal chassis 2 is made up of ferrimagnet, described circuit board 1 is fixed on described metal chassis 2 by magnetic 3.
The structure of magnetic as shown in Figure 7, described magnetic 3 is made up of shell and permanent magnet 4, described shell is made up of support portion 31 and fixed part 30, support portion 31 and fixed part 30 are positioned at the two ends of shell, the end face of described support portion 31 is provided with the accommodating cavity 32 for accommodating described permanent magnet 4, and described fixed part 30 has the flange 33 for fixing described circuit board.Shell can use metal or nonmetallic materials.Described support portion 31 and fixed part 30 preferably one-body molded, such more compact structure, and firmly.In use, the state that accommodating cavity 32 put into by permanent magnet 4 is fastened on accommodating cavity 32, and the customary means by the art is come fastening, blocks permanent magnet 4 as accommodating cavity 32 arranges fastener, or use glue to stick permanent magnet 4.When mounted, after accommodating cavity 32 put into by permanent magnet 4, magnetic is placed in the correct position of circuit board, now, when described permanent magnet 4 is adsorbed on metal chassis 2, because the flange 33 of fixed part blocks circuit board 1, circuit board is fixed on metal chassis.This structure, does not need screw to fix, and directly realizes fixed function by the jam effect of the suction of permanent magnet and the flange of fixed part.That as a kind of preferred version, the end face 36 of described fixed part is mutually concordant with the surface of metal chassis 2 with the back side of circuit board 1, makes described permanent magnet adsorbing when metal chassis, the back side of described circuit board and metal chassis close contact on this basis.The end face 36 of described fixed part can be the end face 35 of accommodating cavity, also can be the end face 41 of permanent magnet, and certainly, the end face 35 of accommodating cavity and the end face 41 of permanent magnet also can be concordant.This structure, the heat that circuit board can be made to produce can be dispelled the heat by metal chassis rapidly.
The first fixed form as shown in Figure 1, Figure 2, Figure 5, described circuit board 1 is provided with through hole, one end of described support portion 31 is adsorbed on described metal chassis 2 through after described through hole, the flange 33 of described fixed part 30 is against the surface of described circuit board 1, here circuit board 1 and metal chassis 2 do not limit shape, can be annular as shown in Figure 1, as shown in Figure 5 square etc.
The second fixed form is as shown in Fig. 3, Fig. 4, Fig. 6, on the circuit card 1 through hole is not set, described magnetic 3 is along surrounding's arrangement of described circuit board 1, and the support portion 31 of described magnetic 3 is adsorbed on described metal chassis 2, and described fixed part 30 is against the edge of described circuit board 1.
The annexes such as circuit board of the present utility model are adsorbed on metal chassis by magnet assemblies, assembling and maintenance process in, do not need specific purpose tool, assembling and easy to maintenance, due to existing with fluorescent tube etc. for its metal chassis of lamp affixed to the ceiling of light source is generally also for be made up of ferrimagnet, can not need to change metal chassis, and directly the fluorescent tube of the inside and driving power are removed, then new boards and driving power is replaced with, then switch on power, can easily transform existing lamp affixed to the ceilings such as families.
