Embodiment
Below in conjunction with accompanying drawing, describe preferred implementation of the present utility model in detail.
As Figure 1-5, the vertical flame-proof explosion-proof shell in the present embodiment comprises: housing department 1, on it, there is an opening 11, and this opening 11 is corresponding thereto in four inwalls 12 between face, and every adjacent two inwalls 12 are with fillet 121 transition; Inner casing portion 2, it is roughly a drawer shape, this inner casing portion 2 inserts in housing department 1, after insertion, end face 21 on it seals opening 11, that is to say, the shape of the identical opening 11 of shape of end face 21, two pin bores 211 are just opened on this end face 21, that this pin bores 211 is arranged in is parallel or vertical with the seamed edge 14 of housing department 1 (usings in Fig. 1 horizontal seamed edge 14 as with reference to being exactly parallel, using seamed edge 14 longitudinally in Fig. 1 as with reference to being exactly vertical) a line on, i.e. dotted line shown in Fig. 1, to form the structure of vertical and respective model.Wherein, housing department 1 is cuboid roughly in the present embodiment, therefore its opening 11 is formed with four inwalls 12 corresponding thereto between face, when cube that alteration of form is other types, the quantity of inwall 12 also can and then change, but the setting of fillet 121 now remains and is arranged on 12 of every two adjacent inwalls.This vertical flame-proof explosion-proof shell improves structure, be specially by housing department 1 upper shed 11 corresponding thereto every adjacent two in the inwall between face 12 be arranged to fillet 121 transition.Like this, than original right angle transition, on the one hand, fillet 121 can be so that the thickness of each of sidewall seamed edge 14 increases; On the other hand, fillet 121 can also provide more firm support force to seamed edge 14.Two aspect combinations, can effectively prevent that the phenomenon of splitting from appearring in seamed edge 14 places, thereby improve the flame-proof explosion-proof performance of whole vertical flame-proof explosion-proof shell, extend its useful life.
As shown in Fig. 4-5, the second end face 23 with respect to end face 21 in inner casing portion 2 can offer recess 231, because the mounting means of vertical varistor device need to be by the horizontally mounted inner casing of piezo-resistance portion 2, therefore offering this recess 231 just can facilitate this kind of mounting means, improves installation effectiveness.As shown in Figure 2, the base angle of recess 241 can also be fillet.The inside of inner casing portion 2 can also be provided with for placing the cushion block (not shown) of the pin of piezo-resistance.
