Utility model content
To this, the purpose of this utility model is to provide a kind of explosion-proof performance reliable plate rear profile explosion proof and corrosion protection signal lamp.
The technical scheme realizing the utility model object is:
A kind of plate rear profile explosion proof and corrosion protection signal lamp, comprise lampshade and housing, housing forward end is located at by described lampshade, and described housing rear end is provided with end cap, and described end cap is provided with cable-through hole, the LED being provided with wiring board in described lampshade and being electrically connected with wiring board; Be provided with supporting plate in described housing, the binding post connecting described wiring board and outer lead is located on described supporting plate, seals between described lampshade and described inner walls; Described supporting plate and described housing connect and fix, and have glue curing formation sealant layer to seal in described supporting plate outer setting, thus described wiring board and external environment are completely cut off.
In technique scheme, described supporting plate is provided with slot, and described slot is inserted in the bottom of described wiring board.
In technique scheme, described inner walls is provided with groove with described sealant layer correspondence position.
In technique scheme, the inwall of described housing forms draw-in groove, the outward flange of described supporting plate and described draw-in groove clamping.
In technique scheme, described end cap is fixedly connected with described supporting plate by screw.
In technique scheme, the bottom of described lampshade is stretched in described housing and is connected and fixed with described supporting plate.
The utility model has positive effect:
(1) in the utility model, clearance seal between described lampshade and housing, supporting plate is fixed and by space shutoff herein by the structure simultaneously adopting clamping and sealant layer to coordinate, because glue has mobility before curing, can by all pore fillings, so just effectively can guarantee that wiring board and external environment are completely isolated, make product have reliable explosion-proof performance.
(2) in the utility model, described supporting plate is provided with slot, and described slot is inserted in the bottom of described wiring board, can realize, to wiring board location, preventing wiring board from rocking by adopting this structure.
(3) in the utility model, described inner walls is provided with groove with described sealant layer correspondence position, so, when injecting glue, glue can fill described groove, thus the sealant layer formed after glue curing can be connected with housing, described sealant layer is effectively avoided to be separated with housing and the situation causing sealing property to decline occurs.

Detailed description of the invention
Do to illustrate below in conjunction with the concrete structure of Figure of description to plate rear profile explosion proof and corrosion protection signal lamp of the present utility model:
A kind of plate rear profile explosion proof and corrosion protection signal lamp, as shown in Figure 1 to Figure 3, it comprises lampshade 1 and housing 2, housing 2 front end is located at by described lampshade 1, described housing 2 rear end is provided with end cap 8, and described end cap 8 is provided with cable-through hole 81, the LED 4 being provided with wiring board 3 in described lampshade 1 and being electrically connected with wiring board 3; Be provided with supporting plate 5 in described housing 2, connect described wiring board 3 and be located on described supporting plate 5 with the binding post 6 of outer lead, outer lead enters described end cap 8 inside through described cable-through hole 81 and is connected with described binding post 6; Seal between described lampshade 1 and described housing 2 inwall; Described supporting plate 5 connects and fixes with described housing 2, and has glue curing formation sealant layer 7 to seal in described supporting plate 5 outer setting, thus described wiring board 3 is completely cut off with external environment.In the present embodiment, clearance seal between lampshade 1 with housing 2 (to coordinate with sealing gasket as adopted fluid sealant, sealing gasket or fluid sealant and seal), supporting plate 5 is fixed and by space shutoff herein by the structure simultaneously adopting clamping and sealant layer 7 to coordinate, because glue has mobility before curing, can by all pore fillings, so just effectively can guarantee that wiring board 3 and external environment are completely isolated, make product have reliable explosion-proof performance.
In the present embodiment, described supporting plate 5 is provided with slot, and described slot is inserted in the bottom of described wiring board 3, can realize locating wiring board 3, preventing wiring board 3 from rocking by adopting this structure.
Further, described housing 2 inwall in the present embodiment is provided with groove 21 with described sealant layer 7 correspondence position, so, when injecting glue, glue can fill described groove 21, thus the sealant layer 7 formed after glue curing can be connected with housing 2, described sealant layer 7 is effectively avoided to be separated with housing 2 and the situation causing sealing property to decline occurs.
In the present embodiment, the inwall of described housing 2 forms draw-in groove 22, the outward flange of described supporting plate 5 and described draw-in groove 22 clamping, be fixed on described supporting plate 5 in described housing 2 by this structure.
