Description
Technical field:
The present invention relates to the technical fields of transmitter, more specifically to a kind of radiation shell of broadcast modulation transmitter
Body.
Background technique:
Transmitter main task is the modulation for completing useful low frequency signal to high frequency carrier, is changed at a certain center
The electromagnetic wave that there is certain bandwidth in frequency, fit through antenna transmitting；It is that can launch signal by certain frequency
Device.Broadcast modulation transmitter is a kind of common transmitter, is provided only with exhaust vent, frequency modulation on current some frequency modulation transmitters
Radiator fan is fixed with inside transmitter, outwardly the temperature in air discharging and radiating or the utilization external world realizes high frequency by radiator fan
The heat dissipation of transmitter；But it is radiated, dust will certainly be sucked in frequency modulation transmitter, dirt accumulation is being sent out using radiator fan
The performance that will affect transmitter on the electronic component inside machine is penetrated, to need to find other radiator structures.
Summary of the invention:
The purpose of the present invention is to the deficiencies of the prior art, and provide a kind of radiation shell of broadcast modulation transmitter
Body can meet the heat dissipation effect of transmitter using the radiating fin outside aluminum shell set, so as to avoid dust into
Enter inside transmitter.
To achieve the above object, The technical solution adopted by the invention is as follows:
A kind of radiating shell of broadcast modulation transmitter, the aluminum shell including rectangle, the quadrangles of aluminum inner walls at
Type has raised line, forms threaded connection hole on the front end face of raised line, on the upper surface and two sidewalls of aluminum hull outside respectively at
Type has several radiating fins, and there are two tilting and opposite limit strips for the two sides molding of aluminum case inside bottom surface, described
Aluminum shell in be plugged with ceramic insulation substrate, the cutting of two right-angled trapeziums is formed on ceramic insulation substrate lower end surface,
Cutting is plugged between limit strip and bears against on the inner sidewall of limit strip；Aluminum shell between the limit strip
Several positioning spiro pits for running through aluminum shell lower end surface are formed on the bottom surface of internal side, positioning spiro pit is bolted with spiral shell
Nail, the end of screw is resisted against on the lower end surface of ceramic insulation substrate.
Preferably, several mounting holes are formed on the ceramic insulation substrate.
Preferably, the radiating fin is evenly distributed on the upper surface and two sidewalls of aluminum shell.
Preferably, the quadrangle of aluminum shell lower end surface forms the bottom thread hole of feet.
Preferably, the power cord via hole of connection aluminum housing cavity is formed on the rear end face of the aluminum shell.
Preferably, in the power cord via hole of the aluminum shell grafting power supply line cableties.
The beneficial effects of the present invention are: it can meet dissipating for transmitter using the radiating fin outside aluminum shell set
Thermal effect, so as to avoid dust from entering inside transmitter；Ceramic insulation substrate fixing circuit board is used simultaneously, realizes aluminum
Shell is dielectrically separated from, and avoids aluminum housing conductive.
Detailed description of the invention:
Fig. 1 is the three-dimensional structural schematic diagram of the present invention；
Fig. 2 is the schematic perspective view of another angle of the present invention；
Fig. 3 is the structural schematic diagram that the present invention faces.
In figure: 1, aluminum shell；11, raised line；12, threaded connection hole；13, radiating fin；14, strip is limited；15, power supply
Line via hole；16, positioning spiro pit；17, bottom thread hole；2, ceramic insulation substrate；21, cutting.
Specific embodiment:
Embodiment: as shown in Fig. 1,2,3, a kind of radiating shell of broadcast modulation transmitter, the aluminum shell including rectangle
1, the quadrangle of 1 inner wall of aluminum shell forms raised line 11, and threaded connection hole 12, aluminum shell are formed on the front end face of raised line 11
Several radiating fins 13, the two sides molding of 1 inside bottom surface of aluminum shell have been separately formed on the upper surface and two sidewalls in 1 outside
There are two tilting and opposite limit strip 14, ceramic insulation substrate 2, ceramic insulation base are plugged in the aluminum shell 1
The cutting 21 of two right-angled trapeziums is formed on 2 lower end surface of plate, cutting 21 is plugged between limit strip 14 and bears against
On the inner sidewall for limiting strip 14；Several are formed on 1 inside bottom surface of aluminum shell between the limit strip 14 to pass through
The positioning spiro pit 16 of 1 lower end surface of aluminum shell is worn, positioning spiro pit 16 is bolted with screw, and the end of screw is resisted against ceramic exhausted
On the lower end surface of edge substrate 2.
Preferably, several mounting holes are formed on the ceramic insulation substrate 2.
Preferably, the radiating fin 13 is evenly distributed on the upper surface and two sidewalls of aluminum shell 1.
Preferably, the quadrangle of 1 lower end surface of aluminum shell forms the bottom thread hole 17 of feet.
Preferably, the power cord via hole 15 of connection 1 inner cavity of aluminum shell is formed on the rear end face of the aluminum shell 1.
Preferably, in the power cord via hole 15 of the aluminum shell 1 grafting power supply line cableties.
Working principle: the present invention is the radiating shell on broadcast modulation transmitter, it can gather outside using aluminum shell 1
Radiating fin 13 meet the heat dissipation effect of transmitter, to can then enter in transmitter to avoid dust instead of fan cooling
