Description
Technical field
The utility model relates to aviation electronics production technical fields, more particularly to prevent fifth wheel from splashing in rack wiring
To the device of printed board.
Background technique
In aviation electronics field, rack wiring has become wherein indispensable important production link.It is routed in rack
In production process, the uncontrollable factors such as artificial, environment can inevitably occur, cause fifth wheel to splash to printed board, therewith
And the risk come is to may cause the phenomenon generation of printed board short circuit.
The mode that being widely used at present prevents fifth wheel from splashing is: will be between socket and printed board with adhesive tape
Gap and socket outlet face carry out bonding protection, after removed from printed board again.Which is time-consuming and laborious, protection effect
Fruit is bad.
Therefore, fifth wheel splashing is prevented just to be particularly important with a kind of highly efficient, practical device.
Summary of the invention
Goal of the invention: a kind of device for preventing fifth wheel from splashing to printed board in rack wiring is proposed, to solve
In rack wiring process, extra splash pollutes printed board, causes the problem of printed board short circuit.
Technical solution:
A kind of device for preventing fifth wheel from splashing to printed board in rack wiring, including outer shield and extension shield, institute
