To achieve these goals, the utility model by the following technical solutions: a kind of circuit board with radome, comprises circuit board body and radome; Upper barricade and lower barricade that described radome comprises rectangle framework, is connected with rectangle framework; Both sides, described rectangle framework top are provided with keeps supplying the chute that barricade horizontally slips, and upper barricade two ends form bent the first flanging of fixing with rectangle framework; Described lower barricade have the posting that can cover in rectangle framework and with the fixing bottom surface of posting lower limb, bottom surface outward flange extends L shaped the second flanging, the sidewall of rectangle framework is provided with for L shaped the second flanging and bends fixing hole clipping; Posting inwall is provided with the locating clip of opening upwards, and circuit board body edges is provided with and can be vertically stuck in the spacer in locating clip; Circuit board body top surface edge place is provided with the location foam that can compress with upper barricade, is provided with and can be connected with bottom surface the also supporting section of support circuit plate body in posting.Chute and the first flanging are set, and removable upper barricade is realized maintenance, installation and the dismounting to circuit board, simple to operation, can realize fixing to upper barricade and framework when bending the first flanging, and this arranges sound construction, stablizes; The second flanging and hole clipping can be by rectangle frame and lower radome fixing firmly, simultaneously simple in structure, install, convenient disassembly, locating clip and spacer can be realized the fixing of circuit board body; Location foam can reduce vibrations and damage circuit board, suffering external force when extruding foam that deformation can occur, and avoids damaging by pressure circuit board, and foam and posting can be clamped in circuit board body in radome jointly; And supporting section can play the effect of support circuit plate, the further load area of increasing circuit plate bottom, improves the stability after circuit board is installed; The radome of this setting, shield effectiveness is good, and Stability Analysis of Structures is firm, and also plays the effect of protective circuit plate, and without being welded and fixed circuit board, cost is lower, and installing/dismounting is easy, easy to maintenance.
As preferably, on described circuit board body, be positioned at circuit element and be arranged with the dividing plate that can contact with rectangle framework outward, the top of this dividing plate can be connected with upper barricade.Dividing plate can intercept magnetic field and the electric field between adjacent circuit element, prevents from interacting between adjacent circuit element.
As preferably, described locating clip can extend and load-carrying surface with contact position, circuit board body bottom surface.This load-carrying surface is set, has further increased the Area of bearing of circuit board body, install more firmly stable.
As preferably, described posting inwall connection board, the radiator of posting, riser and bottom surface hollow and opening upwards in the middle of surrounding, described circuit board body and radiator opening corresponding position form a thermovent, and posting inwall is provided with can be by the hot hole that goes out of extraneous and radiator connection.Radiator and thermovent are accelerated the radiating rate of circuit board body, have strengthened the heat dispersion of circuit board, and then avoid circuit board body to burn out because of excess Temperature, and this radiator structure can not affect the shield effectiveness of radome simultaneously.
In sum, the utlity model has following advantage: barricade is set, keeps supplying slideway, first and second flanging that barricade slides, make the installation, dismounting of radome easily; Facilitate the maintenance of circuit board, foam, posting and supporting section fixing circuit board firmly, also play shockproof, measuring body effect simultaneously; The shield effectiveness of this radome is good, without soldered circuit board body, cost is lower.
