Description
Technical field
It the utility model is related to field of electronics, more particularly to a kind of anti-short-circuit insulating Design of electric energy meter.
Background technology
The more pin connector human welds of pcb board of the prior art, there are GND network copper foils between pad, in pad
Simply reserved between GND networks no less than 10mil distances to distinguish different networks, process of this mode in human weld
In, since pad and the distance between GND networks are too small, obscure between easy heterogeneous networks, fluctuation of service or mistake, make
Into short circuit.
Utility model content
The purpose of this utility model is to provide a kind of anti-short-circuit insulating Design of electric energy meter, silk-screen is provided between pad
Layer, prevents short circuit, distinguishes heterogeneous networks, to ensure that operation is correct and stablizes.
In order to achieve the above object, technical solution provided by the utility model is：Including PCB substrate, in the PCB substrate
Offer through hole, the through hole both ends are connected to pad, in the PCB substrate between the pad adhesion have silk-screen layer, institute
State and copper foil layer is provided with the PCB substrate on silk-screen layer both sides, insulating layer is scribbled on the copper foil layer and silk-screen layer.
The PCB substrate is epoxy glass-fiber-fabric substrate.
The insulating layer is green oil layer.
The beneficial effects of the utility model are：A kind of anti-short-circuit insulating Design of electric energy meter, is provided with silk-screen layer between pad,
Prevent short circuit, distinguish heterogeneous networks, to ensure that operation is correct and stablizes.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
