Abstract
The utility model relates to the field of the electrotechnical porcelain electric appliance production technology, more particularly to a through-wall porcelain bushing with large and small porcelain columns. The through-wall porcelain bushing comprises porcelain columns at the two ends and a flange in the middle. Specifically, the porcelain columns at the two ends are a thick porcelain column and a thin porcelain column; the thick porcelain column has the thick wall and the long length; and the thin porcelain column has the thin wall and the short length. Therefore, the provided through-wall porcelain bushing has advantages of low cost and the capability of meeting the using requirement.
Description
Technical field
The utility model relates to the electroceramics technical field of electric appliances, particularly relates to the wall insulator.
Background technology
Cross porcelain knob and middle flange that the wall insulator comprises two ends, in the prior art, length, thickness, shape of crossing the porcelain knob at wall insulator two ends etc. all is the same, in the process that reality is used, the porcelain knob that is installed in the body of wall outside often will bear higher load, need larger creepage distance, inner is then opposite, and the insulator that prior art is installed has waste, increases the shortcoming of cost.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, provide that a kind of cost is low, the big or small porcelain knob that meets the demands cross the wall insulator.
The technical solution of the utility model is achieved in that the excessively wall insulator of big or small porcelain knob, comprise porcelain knob and the middle flange at two ends, it is characterized in that: the porcelain knob at described two ends is respectively coarse porcelain post and fine porcelain post, further says, described coarse porcelain post jamb is thick, and the fine porcelain post jamb is thin.
Say that further described coarse porcelain column length is large, the fine porcelain column length is little.
The beneficial effects of the utility model are: such cross the wall insulator to have a cost low and satisfy the advantage of instructions for use.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1, flange 2, coarse porcelain post 3, fine porcelain post.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the excessively wall insulator of big or small porcelain knob comprises the porcelain knob at two ends and the flange 1 of centre, and it is characterized in that: the porcelain knob at described two ends is respectively coarse porcelain post 2 and fine porcelain post 3.
Further say, described coarse porcelain post 2 wall thickness, fine porcelain post 3 walls are thin.
Say that further described coarse porcelain post 2 length are large, fine porcelain post 3 length are little.
Claims (3)
