The performance that will affect transmitter on the electronic component inside machine is penetrated, to need to find other radiator structures.
Utility model content:
The purpose of the utility model is to solve the deficiencies of the prior art, and provides a kind of dissipating for broadcast modulation transmitter
Hot shell can meet the heat dissipation effect of transmitter, using the radiating fin outside aluminum shell set so as to avoid ash
Dirt enters inside transmitter.
To achieve the above object, the technical solution adopted in the utility model 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 utility model has the beneficial effects that: it can meet transmitter using the radiating fin outside aluminum shell set
Heat dissipation effect, so as to avoid dust from entering inside transmitter；Ceramic insulation substrate fixing circuit board is used simultaneously, is realized
Aluminum shell is dielectrically separated from, and avoids aluminum housing conductive.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model solid；
Fig. 2 is the schematic perspective view of another angle of the utility model；
Fig. 3 is the structural schematic diagram that the utility model is faced.
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 utility model is the radiating shell on broadcast modulation transmitter, it can be gathered using aluminum shell 1
External radiating fin 13 meets the heat dissipation effect of transmitter, to can then enter transmitting to avoid dust instead of fan cooling
Inside machine；2 fixing circuit board of ceramic insulation substrate is used simultaneously, realizes being dielectrically separated from for aluminum shell 1, aluminum shell is avoided to lead
