Description
Technical field
The utility model relates to field of electrical equipment, more specifically, it relates to a kind of composite insulator.
Background technique
Currently, in the power system, generator, transformer, insulator are main three-major-items.Insulator is through defeated change
Each of electricity link, insulator can be divided into glass, ceramics and composite insulator by insulator material.One end by glue join,
It the modes such as fills, crimp, being bolted to be attached insulator and fitting, the other end is equipped with thimble, is used for and cable connects
Connect fixation.And overhead insulation is highly prone to external force often by wind-force, the big effect of rain, when insulator is by external force, holds
It is also easy to produce instantaneous biggish impact force, insulator and fitting will increase the risk of slippage over time.Or cable is excessively pullled
Thimble causes thimble to damage.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of mounted configuration intensity height,
A kind of better composite insulator of fastness.
To achieve the above object, the utility model provides following technical solution:
A kind of composite insulator, including insulating body, insulating body outer surface are equipped with rubber full skirt, and end is equipped with threading
Ring, tail end are equipped with mounting base, are equipped with the mounting hole worn for bolt in the mounting base, the two sides of the mounting hole are equipped with bullet
Property cushion block is fixedly connected with support rod on the elastic cushion block, and the support rod is arranged in mounting base, is set in the thimble
Have a reinforcing ring made of metal, the reinforcing ring includes outer ring, inner ring and connecting column, the inner ring be located in outer ring and
The two is concentric, and the inner wall of one end of connecting column and outer ring connects, and the outer wall of the other end and inner ring connects, the thimble it is interior
Wall is equipped with internal screw thread, and the outer wall of outer ring is equipped with internal screw thread, and the thimble and outer ring are threadedly engaged fixation.
The utility model is further arranged to: the connecting column is arranged in X-shaped, and the thickness of the outer ring is greater than the thickness of inner ring
Degree.
The utility model is further arranged to: the elastic cushion block is made of insulating material.
By using above-mentioned technical proposal, elastic cushion block is set in the mounting base of insulating body tail end, insulator by
It to when biggish impact, can be buffered, prevent insulator Large Amplitude Motion from causing to fall off.Reinforcement is added in connecting ring
Ring, so that the structural strength of connecting ring is higher, when insulator is by significantly impacting, even if connecting ring is high-strength by cable
Pullling for degree is also hardly damaged.

Specific embodiment
Implement example to the utility model composite insulator referring to Fig.1 to be described further.
A kind of composite insulator, including insulating body 1,1 outer surface of insulating body are equipped with rubber full skirt 2, and end is equipped with
Thimble 3, tail end are equipped with mounting base 4, in the mounting base 4 equipped with the mounting hole 40 worn for bolt, the mounting hole 40
Two sides be equipped with elastic cushion block 5, be fixedly connected with support rod 50 on the elastic cushion block 5, the support rod 50 is arranged in installation
In seat 4, reinforcing ring 6 made of metal is equipped in the thimble 3, the reinforcing ring 6 includes outer ring 60,61 and of inner ring
Connecting column 62, the inner ring 61 is located in outer ring 60 and the two is concentric, and one end of connecting column 62 is connect with the inner wall of outer ring 60,
The other end is connect with the outer wall of inner ring 61, and the inner wall of the thimble is equipped with internal screw thread, and the outer wall of outer ring 60 is equipped with interior spiral shell
Line, the thimble and outer ring 60 are threadedly engaged fixation.The connecting column 62 is arranged in X-shaped, and the thickness of the outer ring 60 is greater than
The thickness of inner ring 61.The elastic cushion block 5 is made of insulating material.
When insulator is shaken by external force, the elastic cushion block 5 in mounting base 4 can alleviate rushing for a part
The vibration that the junction hit power, while reducing bolt and mounting base 4 generates, so that avoiding insulator from generating bigger rocks power.
Elastic cushion block 5 is fixed in mounting base 4 by support rod 50, can promote the installation fastness of elastic cushion block 5, is effectively avoided absolutely
Edge is fallen.Since the connecting ring position of end is arranged with cable, for insulator when by rocking energetically, connecting ring can be by very big
Pull power, in connecting ring be equipped with reinforcing ring 6, the structural strength of connecting ring can be promoted, prevent from damaging, reinforcing ring 6 be arranged
At the dual structure of inner ring 61 and outer ring 60, so that the structural strength of reinforcing ring 6 is high, connection is equipped between inner ring 61 and outer ring 60
Column 62 can promote the bearing capacity of reinforcing ring 6.Outer ring 60 is cooperated by screw thread and connecting ring, is realized easy to assembly.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
