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 control button.
The technical scheme realizing the utility model object is:
A kind of plate rear profile explosion proof and corrosion protection control button, comprise housing and be located at the contact apparatus in described housing, described housing rear end is provided with end cap; Described end cap is provided with cable-through hole; Described contact apparatus comprises base shell, be located at the contact assembly in described base shell and be located at the connector assembly of described base shell rear end; Described base shell lateral wall is provided with flange, the catching groove clamping in described flange and described inner walls; The described flange outer setting of described base shell has glue curing to form sealant layer.
In technique scheme, in described housing, be provided with excessive glue groove with described catching groove correspondence position.
In technique scheme, the top of described excessive glue groove inwall is provided with gear glue groove.
In technique scheme, the both sides of described flange are provided with location notch, and in described housing, correspondence position is provided with the positioning boss coordinated with described location notch.
In technique scheme, described base shell is also provided with baffle plate with described contact assembly correspondence position.
In technique scheme, described end cap is fixedly connected with described base shell by screw.
The utility model has positive effect:
(1) in the utility model, described contact apparatus is fixed in described housing, and by arranging sealant layer by the hole shutoff on base shell and between base shell and described housing, because glue has mobility before curing, all holes fully can be filled, so just effectively can guarantee that contact assembly and external environment are completely isolated, make product have reliable explosion-proof performance; When injecting glue, glue can enter in described catching groove, thus the sealant layer formed after glue curing can be connected with housing, effectively avoids described sealant layer to be separated with housing and the situation that causes sealing property to decline occurs.
(2), in the utility model, be provided with excessive glue groove with described catching groove correspondence position in described housing, glue unnecessary during glue can flow in excessive glue groove, in case fluid stopping has influence on the conductivity of dynamic/static contact to contact assembly place.
(3) in the utility model, the top of described excessive glue groove inwall is provided with gear glue groove, can play by arranging gear glue groove the effect stopping glue further.
(4) in the utility model, described base shell is also provided with baffle plate with described contact assembly correspondence position, by adopting this structure can prevent glue from entering contact apparatus inside further thus affect the conductivity of dynamic/static contact, baffle plate also plays the effect of spacing moving contact simultaneously.
