Abstract
The utility model discloses a kind of pressure resistant type wall bushing, include conducting rod, conducting rod is coated with insulating case, insulating case outer wall is distributed with increasing and climbs full skirt, conducting rod two ends are all provided with binding post, in the middle part of insulating case, adpting flange is installed, adpting flange is connected to some support convex tendons be centered around outside insulating case along edge joint weld, some support convex tendons are equipped with resistance to pressure cylinder, withstand voltage tube rear end is fixedly mounted on adpting flange side, and front end is provided with the dust protection rubber pipe tightened up on insulating case outer wall.The utility model is simple and reasonable, easy to install, adopt the design that resistance to pressure cylinder is set in the insulating case periphery of wall bushing, effectively improve anti-pressure ability, in laying construction and later stage use procedure, be not subject to ambient pressure and cause insulating case impaired, ensure that the safety in utilization of insulating case, there is the dirt exclusion capabilities added simultaneously, extend the useful life of wall bushing.
Description
Technical field
The utility model relates to electric fittings field, is specially a kind of pressure resistant type wall bushing.
Background technology
Wall bushing is that high voltage source is passed through wall, guides outdoor into or guide indoor into by indoor by indoor, also or inside and outside high-voltage switch gear or transformer passes through the device that shell wall carries out high voltage source guiding.And existing wall bushing structure is reasonable not, it is convenient not to install, withstand voltage properties is not good, hold susceptible to outside pressure and impaired with insulating case in later stage use procedure after mounting, easily there is dust and fall into or inundation in breakage, and then easily cause high-voltage connection loose contact, affect line security.
Utility model content
The purpose of this utility model is to provide a kind of pressure resistant type wall bushing, reasonable not to solve wall bushing structure traditional in prior art, it is convenient not to install, withstand voltage properties is not good, hold susceptible to outside pressure and impaired with insulating case in later stage use procedure after mounting, easily there is dust and fall into or inundation in breakage, and then easily causes high-voltage connection loose contact, affects the problem of line security.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of pressure resistant type wall bushing, it is characterized in that: include conducting rod, described conducting rod is coated with insulating case, described insulating case outer wall is distributed with increasing and climbs full skirt, described conducting rod two ends are all provided with binding post, in the middle part of described insulating case, adpting flange is installed, described adpting flange is connected to some support convex tendons be centered around outside insulating case along edge joint weld, described some support convex tendons are equipped with resistance to pressure cylinder, described withstand voltage tube rear end is fixedly mounted on adpting flange side, and front end is provided with the dust protection rubber pipe tightened up on insulating case outer wall.
Described a kind of pressure resistant type wall bushing, is characterized in that: the described inwall of resistance to pressure cylinder is distributed with some anti-tracking annular grooves.
The beneficial effects of the utility model are:
The utility model is simple and reasonable, easy to install, adopt the design that resistance to pressure cylinder is set in the insulating case periphery of wall bushing, effectively improve anti-pressure ability, in laying construction and later stage use procedure, be not subject to ambient pressure and cause insulating case impaired, ensure that the safety in utilization of insulating case, there is the dirt exclusion capabilities added simultaneously, extend the useful life of wall bushing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
