Abstract
The utility model discloses a kind of screening arrangement of voltage regulator, this voltage regulator by shielding cassette holder, component circuit board assembly, shielding socket, insulating heat-conductive solidify glue, lid and some securing members etc. and form; Component circuit board assembly is fixed in shielding cassette holder by screw, its line is connected with shielding socket, thermal plastic insulation is poured into and through regular hour Post RDBMS after installation, thermal plastic insulation after solidification can guarantee the good heat conductive effect between radiating element in component circuit board and cassette holder, and carry out diffusion type heat radiation by the fin on cassette holder, lid to be arranged on cassette holder by conducting resinl, screw and to form a closed shield body, makes this voltage regulator not only have good radiating effect but also has the high screening effectiveness of electromagnetic field.
Description
Technical field
The present invention relates to a kind of screening arrangement, particularly relate to a kind of screening arrangement of voltage regulator of diffusion type radiating mode.
Background technology
The version of voltage regulator is a lot, and the existing air-cooled heat dissipation structure utilizing fan suction wind of its radiating mode, also has the radiator structure of the direct open type of component circuit board.Because component circuit board assembly operationally can along with the radiation of electromagnetic field, the electromagnetic field radiation of voltage regulator becomes interference source, along with the application of generating set in mobile communications industry, communication equipment can produce noise because of Electromagnetic Interference and affect communication quality.Therefore, must a kind of voltage regulator with electromagnetic field height screening effectiveness of research.
Summary of the invention
The object of the present invention is to provide a kind of screening arrangement of voltage regulator, this device is by the heat conduction between component circuit board and cassette holder and carry out diffusion type heat radiation by the fin on cassette holder, and lid to be arranged on cassette holder by conducting resinl, screw and to form a closed shield body.Make this voltage regulator not only have good radiating effect but also there is the high screening effectiveness of electromagnetic field.
The present invention is achieved like this, a kind of screening arrangement of voltage regulator, it mainly comprises shielding cassette holder, component circuit board assembly, shielding socket, insulating heat-conductive solidification glue, lid, circuit board hold-down screw, lid hold-down screw, socket hold-down screw and conducting resinl, it is characterized in that: component circuit board assembly is fixed in shielding cassette holder by circuit board hold-down screw, its line is connected with shielding socket, shielding socket is fixed by socket hold-down screw, component circuit board assembly pours into thermal plastic insulation and through regular hour Post RDBMS after installing, thermal plastic insulation after solidification can guarantee the good heat conductive effect between radiating element in component circuit board and cassette holder, and carry out diffusion type heat radiation by the fin on cassette holder, lid passes through conducting resinl, screw to be arranged on cassette holder and to form a closed shield body.
Described flange-cooled shielding cassette holder is integral type die casting.
Technique effect of the present invention is: the present invention is by the heat conduction between component circuit board and cassette holder and carry out diffusion type heat radiation by the fin on cassette holder, and lid to be arranged on cassette holder by conducting resinl, screw and to form a closed shield body.Make this voltage regulator not only have good radiating effect but also there is the high screening effectiveness of electromagnetic field.

Fig. 4 is the B-B profile of the shielding construction of voltage regulator.
In the drawings, 1, shielding cassette holder 2, circuit board hold-down screw 3, component circuit board assembly 4, shielding socket 5, socket hold-down screw 6, insulating heat-conductive solidification glue 7, lid hold-down screw 8, lid.
Embodiment
The present invention carrys out work like this, as Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4, it is by shielding cassette holder 1, circuit board hold-down screw 2, component circuit board assembly 3, shielding socket 4, socket hold-down screw 5, insulating heat-conductive solidification glue 6, the compositions such as lid hold-down screw 7 and lid 8, the component circuit board assembly 3 of this voltage regulator is fixed in shielding cassette holder 1 by circuit board hold-down screw 2, the line of component circuit board assembly 3 is connected with shielding socket 4, shielding socket 4 is fixed by socket hold-down screw 2, insulating heat-conductive fixing glue 6 is poured into and through regular hour Post RDBMS after installation, thermal plastic insulation 6 after solidification can guarantee radiating element in component circuit board 3 and the good heat conductive effect between shielding cassette holder 1, and carry out diffusion type heat radiation by the fin on shielding cassette holder 1, lid 8 is by smearing conducting resinl at the installed surface of shielding cassette holder 1 and be fixed by lid hold-down screw 7, whole voltage regulator shell forms a closed shield body, make this voltage regulator not only have good radiating effect but also there is the high screening effectiveness of electromagnetic field.
Operation principle of the present invention: the component circuit board assembly 3 in voltage regulator in working order time be emission source and calorie source.Due to the conduction of heat of thermal plastic insulation 6, the heat conduction that component circuit board assembly 3 sends extremely shields the fin on cassette holder 1 and derives.Again because whole voltage regulator shell forms a closed shield body, this voltage regulator is made to have the high screening effectiveness of electromagnetic field.
