Abstract
The utility model relates to a kind of field frame assembly casing, has housing; The inwall of described housing is provided with multiple connecting hole along housing circumference array; Described connecting hole outwards comprises aperture and big hole successively from the inwall of housing, and aperture is coaxial with big hole and be connected; Described big hole is blind hole, and aperture forms shoulder block in the aperture of big hole.The utility model can be avoided offering connecting through hole on housing, reduces the risk that field frame assembly in use seeps water, improves fail safe and the life-span of field frame assembly.
Description
Technical field
The utility model relates to field frame assembly parts, particularly a kind of field frame assembly casing.
Background technology
Field frame assembly comprises housing, magnetic pole and solenoid.Be bolted when conventional housings is connected with magnetic pole, and in order to easy to connect, on housing and magnetic pole, stamp connecting through hole often.There is the hidden danger of infiltration in such syndeton, once field frame assembly infiltration, will cause potential safety hazard and reduce useful life.Field frame assembly in use can produce heat, and the accumulation of heat can affect the result of use of field frame assembly, and therefore how dispelling the heat also is the direction of present product research.
Utility model content
The purpose of this utility model is to provide a kind of good water-proof effect, field frame assembly casing easy to connect.
The technical scheme realizing the utility model object is: the utility model has housing; It is characterized in that: the inwall of described housing is provided with multiple connecting hole along housing circumference array; Described connecting hole outwards comprises aperture and big hole successively from the inwall of housing, and aperture is coaxial with big hole and be connected; Described big hole is blind hole, and aperture forms shoulder block in the aperture of big hole.
The pass of above-mentioned aperture is oval; The length of the major semiaxis of described aperture is the radius of big hole.
The inwall of above-mentioned housing there is arc vent rib to two ends linear array centered by connecting hole.
The utility model has positive effect: (1) the utility model offers connecting hole on the inwall of housing, and connecting hole is not through hole, effectively can avoid the infiltration risk of casing, improves useful life and the fail safe of field frame assembly; (2) the utility model is in the mode of the outer setting aperture of big hole, is to improve connective stability.(3) the utility model can form space by between magnetic pole and housing by arc vent rib, can increase the thermal diffusivity of enclosure interior, improves product result of use.
Accompanying drawing explanation
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged drawing at A place in Fig. 1.
Embodiment
See Fig. 1 and Fig. 2, the utility model has housing 1; The inwall of described housing 1 is provided with multiple connecting hole 2 along housing circumference array; Described connecting hole 2 outwards comprises aperture 21 and big hole 22 successively from the inwall of housing 1, and aperture 21 is coaxial with big hole 22 and be connected; Described big hole 22 is blind hole, and aperture 21 forms shoulder block in the aperture of big hole 22.
The pass of described aperture 21 is oval; The length of the major semiaxis of described aperture 21 is the radius of big hole 22.
The inwall of described housing 1 there is arc vent rib 3 to two ends linear array centered by connecting hole 2.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
