The second layer pcb board for being equipped with low-voltage circuit is designed as double-decker and connected by conductive stud, has abandoned existing fly line and has connected
Mode is connect, the design of double-decker make it that the isolation distance between high-tension circuit and low-voltage circuit is bigger, anti-tampering property and safety
Property it is more preferable, and the topology layout inside power amplifier can be optimized, efficiently reduce PCB surface product, help to reduce product
Size, the cost of product is greatly lowered,；Conductive stud can both play electric action, can play a supporting role again, solution
Determined between existing power amplifier mesohigh circuit and low-voltage circuit using fly line connection by the way of existing for cost higher
Technical problem；The accurate connection of conductive stud and first layer pcb board and second layer pcb board is it is possible to prevente effectively from the easy wrong of fly line
Technical problem；And conductive stud can compare with securely locking high-voltage transmission contact surface, solve existing power amplification
Can be due to the larger docking Plugin Requirement of the power of transmission by the way of fly line connection between device mesohigh circuit and low-voltage circuit
Higher technical problem, at the same also solve for a long time easily produced using the contact portion of rear connector because of oxidation it is larger
Impedance such as is even generated heat, struck sparks, be on fire at the technical problem of even more serious consequence so as to produce loose contact.
2nd, the embodiments of the invention provide a kind of power amplifier, the double-decker of first layer pcb board and second layer pcb board
So that between first layer pcb board and the second layer pcb board formation rule ventilating duct, and solve work(caused by fly line connected mode
Rate amplifier internal wire arranges at random, space-consuming so as to influence the technical problem of the circulation of air, and ventilating duct is with dissipating
Hot hole and radiator fan coordinate, and radiating can be better achieved, and improve the life-span of power amplifier component.
