[specific embodiment]
The utility model is described in further detail below in conjunction with the accompanying drawings, the structure and principle of this device people professional to this
For be very clearly.It should be appreciated that specific embodiment described herein is only to explain this utility model, and without
In restriction this utility model.
This utility model is a kind of protective plate for low-voltage electrical apparatus, and first, second protective plate and interface end daughter board are fixed
Afterwards, silica gel is imported between the first protective plate, the second protective plate and terminal, the inside and outside use ring of isolation low-voltage electrical apparatus
Border.
Fig. 1～Fig. 4 is an example of the present utility model, and Fig. 2 is the first protective plate, is placed on the back of the body of interface end daughter board
, there are 4 connecting holes and 3 connecting poles in face on the first protective plate, wherein connecting hole is used for connecting interface terminal board, and connecting pole is used for
Connect the second protective plate, be provided with the location hole passed through for connecting pole on interface end daughter board.Meanwhile, also set on interface end daughter board
