As shown in fig. 1 to 4, a circuit board convenient for installation and fixation comprises a circuit board body 1 and a mounting plate 2, wherein two sides of the bottom of the circuit board body 1 are provided with fixing columns 3, in this embodiment, 4 fixing columns 3 are provided, through holes 4 are provided on the fixing columns 3, a fixing groove 5 is provided on the mounting plate 2 corresponding to the fixing columns 3, the size of the fixing groove 5 is adapted to the size of the fixing columns 3, the outer side wall of the fixing groove 5 is provided with elongated limiting holes 6 which are vertically arranged, the upper and lower ends of the limiting holes 6 are closed, the upper end of the outer side wall of the fixing groove 5 is provided with a fixing hole 7 communicated with the limiting hole 6, a fixing screw 8 is provided in the fixing hole 7, the inner side wall of the fixing groove 5 is provided with an elongated limiting groove corresponding to the limiting hole 6, the bottom surface of the fixing groove 5 is provided with a spring 9, the upper end of the, the fixing column 3 is limited in the fixing groove 5 through the limiting screw rod 11, wherein the limiting screw rod 11 penetrates through the limiting hole 6 and the through hole 4 in sequence and finally abuts against the limiting groove. Wherein, can design into threaded connection with stop screw 11 and through-hole 4, be equipped with the external screw thread on stop screw 11 surface promptly, be equipped with in through-hole 4 inner wall with external screw thread assorted internal thread, can be so that the two threaded connection together, likewise, design into threaded connection's mode with clamping screw 8 and fixed orifices 6.
Further, a heat-conducting silica gel gasket 12 is arranged between the circuit board body 1 and the mounting plate 2, a plurality of V-shaped heat dissipation fins 13 are arranged on the upper portion of the mounting plate 2, an air duct 14 is arranged between the heat dissipation fins 13 and the bottom surface of the mounting plate 2, and a plurality of heat dissipation fins 15 are arranged on the side edge of the circuit board body 1. The heat-conducting silica gel gasket 12 is made of silica gel as a base material, various auxiliary materials such as metal oxides are added, and a heat-conducting medium material is synthesized through a special process, so that gaps can be filled, a heat channel between a heating part (namely the position of the circuit board body 1 where the electronic component is installed) and a radiating part is opened, the contact thermal resistance generated between the surface of a heat source and the top surface of the mounting plate 2 is reduced, the heat transfer efficiency is effectively improved, and the heat dissipation from the radiating fins is accelerated; in addition, the heat-conducting silica gel gasket 12 has certain elasticity, and can also play roles of insulation, shock absorption, sealing and the like, so that the circuit board body 1 can be effectively protected, and the damage of the circuit board body is avoided. The bottom of the mounting plate 2 is provided with the ventilation channel 14, so that air is circulated at the bottom of the mounting plate 2, and when the electronic components on the circuit board body 1 work to generate a large amount of heat, the heat can be transferred to the outside along with flowing air through the ventilation channel 14, so that the temperature of the circuit board body 1 is reduced; the heat dissipation fins 15 can accelerate heat dissipation from the upper surface of the circuit board body 1, and the design enables the heat dissipation parts to be arranged on the upper surface and the lower surface of the circuit board body 1 to help heat dissipation, so that heat dissipation is accelerated further, and heat dissipation rate is improved. And mounting holes 16 are formed at four corners of the mounting plate 2 and used for fixedly mounting the mounting plate 2.
The utility model discloses when installing, insert fixed slot 5 with the fixed column of circuit board body 1 in, then pass spacing hole 6 with stop screw 11 in proper order from 5 lateral walls of fixed slot, through-hole 4, at last with clamping screw 8 precession downwards, clamping screw 8's tail end then constantly pushes down clamping screw 11, thereby drive fixed column 3 and push down gradually, and fixed column 3 then passes through fly leaf 10 compression spring 9 gradually, adjust circuit board body 1 to when suitable height, stop precession clamping screw 8, continue simultaneously with stop screw 11 precession inwards, until tightly the butt in the spacing groove with its tail end, can fix fixed column 3 in fixed slot 5. Through the cooperation of above components, solved the circuit board and welded in an organic whole when the installation, the maintenance personal of being not convenient for carries out the problem of maintaining.
Compared with the prior art, the utility model has the advantages of the fixed height that still lies in adjustable circuit board body 1. This is because the various electronic components on the circuit board body 1 are not completely identical in size and height, and some electronic components have a high longitudinal height and may be pushed against the housing of the circuit board during mounting, resulting in housing failure. In the prior art, the fixed height of the connection between the circuit board body 1 and the mounting plate 2 is fixed and has no room, and once the two are connected together, there is basically no room for adjusting the height, which may cause the above problems. The movable plate 10 connected with the spring 9 is disposed in the fixing groove 5 of the present invention, so that the movable plate 10 can move up and down elastically, when there are electronic components with a higher height on the circuit board body 1, the limit screw 11 can be pressed downwards through the fixing screw 8, and then the fixing column 3 is driven to move downwards through the limit screw 11, thereby driving the whole circuit board body 1 to move downwards, because the heat-conducting silica gel gasket 12 has certain elasticity, therefore, a certain compression allowance is left between the circuit board body 1 and the mounting plate 2, so that the circuit board body 1 can be pressed downwards to shorten the distance between the circuit board body and the mounting plate 2, while the spring 9, compressed by the fixed post 3, now has an upward restoring force, while the fixed screw 8 has a downward pressure, the limit screw 11 has an inward pressure, so that, the fixing posts 3 are firmly fixed in the fixing slots 5 by the forces in the three different directions.
Finally, it should be noted that: these embodiments are merely illustrative of the present invention and do not limit the scope of the invention.
