Specific implementation mode
To make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, below
In conjunction with specific implementation mode, the utility model is expanded on further.
As shown in Figs. 1-3, a kind of digital and electronic crossover sub, including A/D converter 1,4 and of analog signal input adapter
Data-signal out splice going splice 6, the inside of A/D converter 1 are equipped with mainboard 8, and the side of mainboard 8 is equipped with cooling fan 7, and mould/
The side of number converter 1 is equipped with connector 9, and the other side of A/D converter 1 sets that there are two usb 10, A/D converters 1
Both ends by data line 3 respectively with analog signal input adapter 4 and data-signal out splice going splice 6, mainboard 8 is defeated by analog signal
Entering the analog signal that connector 4, connector 9 and the transmission of two usb 1s 0 are come in, to be converted into digital signal defeated by data-signal
Go out connector 6 to transfer out, realize and analog signal is converted by digital signal by external A/D converter 1, not convenient for two kinds
With between the equipment of signal mode connection and information transmission, cooling fan 7 radiates to A/D converter 1, ensure mould/
Number converter 1 can continue working, connector be JAE TX25 series connectors.
Wherein, the surface of A/D converter 1 is laid with by antistatic backing, is prevented because accumulation of static electricity leads to A/D converter
Mainboard 8 in 1 is burnt out.
Wherein, the surface of A/D converter 1 offers several equally distributed heat emission holes 5, and several heat emission holes 5
It is correspondingly arranged with cooling fan 7, ensures the heat generated when cooling fan 7 in time works A/D converter 1 from heat emission hole 5
Discharge.
Wherein, the surface of A/D converter 1 is equipped with work display lamp 2, and work display lamp 2 inputs lamp by analog signal
With data-signal output lamp group at analog signal input lamp shows that analog signal input adapter 4 or connector 9 or two USB connect
