Have and prevent there are two at least inserts nuts an insulator both ends design promptly by rotating -structure from the area, when the inserts nut is connected with electrified spare part, adopt the fixed mode of line to reach and prevent the pivoted mesh, simultaneously, the insulator adopts the BMC material, but its have accurate control size, fire resistance and anti track nature well, very high dielectric strength, corrosion -resistant resistance to soiling and aging resistance is good, and advantage such as mechanical properties brilliance.
Description
Technical field
The utility model relates to a kind of electric fittings, particularly relates to a kind of anti-rotation insulated column.
Background technology
Insulated column is for the relevant device in the fields such as communication cabinet, electric power electric, lightning protection, machinery, medical treatment, wind energy, frequency conversion equipment provides instructions for use, mounting means and the around particular component that needs of applied environment, it mainly plays fixed support, connection and insulating effect to band electric parts, also can be referred to as insulator, insulation gap post.But, during current insulated column fixed support band electric parts, as the design of band electric parts anti-rotation will be realized, just need to use at least two insulated columns with the use of, just can reach the object of anti-rotation.So, one is to cause the use cost of insulated column to improve; Two is that insulated column can take larger erection space and space.
Utility model content
Technical problem to be solved in the utility model overcomes above-mentioned the deficiencies in the prior art, provides a kind of anti-rotation insulated column.
The technical scheme in the invention for solving the above technical problem is: a kind of anti-rotation insulated column, and comprise and adopt BMC and cross section to be the column insulator of capsule shape, insulator two ends form the first end face and the second end face that are parallel to each other; First, second end face described offers respectively at least two not through installing holes, the embedded intrinsic insert nut of described installing hole, insert nut described in one of them is fitted with alignment pin; Described insulator lateral surface is covered with watertight composition and flame retardant coating successively.
The cylinder of described insulator is surrounded with spaced annular protrusion.
Described watertight composition is mono-component polyurethane material coating.
Described flame retardant coating is high temperature inorganic coating.
Described insert nut adopts round nut or hex nut.
Described alignment pin is column structure, prism structure or six prism structures.
Compared with prior art, the beneficial effects of the utility model:
1. have and carry anti-rotation structure, namely at least two insert nuts are designed with at insulator two ends, when insert nut is connected with band electric parts, adopt line fixed form, thus reach the object of anti-rotation, and can the use amount of effective less insulated column, reduce costs, reduce the area shared by installing and space, have structure simple, be easy to the advantages such as installation.
2. simultaneously, insulator adopts BMC, its have can precise control of sizes, anti-flammability and tracking resistance well, very high dielectric strength, corrosion-resistant resistance to soiling and the advantage such as resistance to ag(e)ing is excellent and mechanical performance is remarkable, flame retardant rating can reach UL94V-0 highest level.

Fig. 2 is the side structure schematic diagram of the utility model preferred embodiment;
Fig. 3 is the insulator superstructure schematic diagram of the utility model preferred embodiment.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described further.
Refer to Fig. 1 and Fig. 2, a kind of anti-rotation insulated column of the utility model preferred embodiment design, comprising: insulator 100 and at least four insert nuts 103, insert nut 103 adopts the mode of in-mould injection to be mounted on insulator 100.
Particularly, insulator 100 is designed to the column structure that cross section is capsule shape, also can be designed to the shape that other are suitable, such as hexagon or cylindrical.The two ends of insulator 100 form the first end face 101 respectively and are parallel to the second end face 102 of the first end face 101.The cylinder of insulator 100 is surrounded with multiple spaced annular protrusion 105, insulator 100 outer surface is made to be formed wavy with this, this wavy surface is beneficial to increase creepage distance, prevent dust from being formed and path in the attachment of insulator 100 outer surface, prevent the situation that both end voltage punctures.Refer to Fig. 3, be also coated with waterproof 110 at the lateral surface of insulator 100, be coated with flame retardant coating 120 at the lateral surface of watertight composition 110, watertight composition 110 and flame retardant coating 120 is tight wraps whole insulated column, the operational environment of moist overcast and rainy, the high temperature that is exposed to the sun can be adapted to.
First end face 101 of insulator 100 offers first installing hole of at least two, build-in insert nut 103 in this first installing hole.In like manner, the second end face 102 of insulator 100 offers second installing hole of at least two, build-in insert nut 103 in this second installing hole.Insert nut 103 one_to_one corresponding on first end face 101 and the second end face 102, and do not connect.Insert nut 103 preferably adopts round nut or hex nut.
Sometimes need in order to actual installation uses, one of them insert nut 103 on the first end face 101 needs plug-in mounting alignment pin 104, alignment pin 104 correspondence is inserted in the location hole of band electric parts.Alignment pin 104 can be designed to column structure, prism structure or six prism structures etc.
Further, insulator 100 preferably adopts BMC manufacture, i.e. unsaturated polyester resin glass fibre reinforced mould plastic material, has very excellent combination property, meets very much the instructions for use of insulated column.Flame retardant coating 120 preferably adopts high temperature inorganic coating, and watertight composition 110 preferably adopts mono-component polyurethane material coating.
Further, insert nut 103 and alignment pin 104 preferably adopt these the three kinds of material manufactures of copper, aluminium or steel.
When mounted, use two screw rods to pass in the shell of the products such as cabinet, on the insert nut of one end grafting second end face, the other end is plugged in the corresponding nut of cabinet inside the utility model; And be supported on the first end face of insulator with electric parts, use the screw elements such as a bolt to be inserted on the insert nut of the first end face, alignment pin correspondence is inserted in the location hole on band electric parts simultaneously, thus realize fixing the support of band electric parts.
Insulated column insulation resistance of the present utility model is greater than 500M Ω, and operating temperature range, at-30 DEG C ~ 120 DEG C, is the product that combination property is very excellent.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
