Specific implementation mode
In the following, the substantive distinguishing features and advantage of the utility model are further described in conjunction with example, but this practicality is new
Type is not limited to listed embodiment.
As shown in Figures 1 to 5, a kind of wiring board waterproof construction of the present embodiment includes box body 1, cover board 2, bolt 3 and close
Packing 4, wiring board 5 are arranged in box body 1, and cover board 2 is arranged above box body 1.Cover board 2 is equipped with screw hole 21, and screw hole 21 is through lid
Plate, bolt 3 are arranged in screw hole 21.Bolt 3 has accommodating chamber 31 and bottom plate 32, and water absorbing agent 6, this implementation are equipped in accommodating chamber 31
Water absorbing agent is calcium oxide in example.The setting of bottom plate 32 is equipped with through-hole 321 in 31 bottom of accommodating chamber, bottom plate 32.The gasket 4 is set
It sets between box body and cover board, box body 1 is equipped with groove 7, and gasket 4 is arranged in a groove.Gasket 4 includes the first wall portion
41, the second wall portion 42, lug boss 43 and lower end 44, the setting of the first, second wall portion in gasket both sides, the first wall portion 41 with it is recessed
The first side 71 of slot 7, the second wall portion 42 are contacted with the second side 72 of groove, and the lug boss 43 is located at 7 top of groove, institute
