Abstract
Provided is a rod-shaped insulator which comprises an insulator equipped with an umbrella skirt and a metallic pedestal. The metallic pedestal is mounted on the two ends of the insulator and is bonded with the insulator through cement adhesive. A groove is disposed on the metallic pedestal on one end of the insulator. A pin hole is disposed in the groove. The rod-shaped insulator has characteristics of simple structure, uneasily-peeled metallic pedestal and the insulator, and a long service life.
Description
Technical field
The utility model relates to a kind of insulator, especially refers to a kind of rod insulator.
Background technology
The insulation control can play an important role in overhead transmission line.Now, insulator slowly develops for high type high-tension bus-bar connection tower, can increase creepage distance.Insulator plays two basic roles in overhead transmission line, it is support wire and prevent that electric current from going back to ground, these two effects must be guaranteed, insulator should be owing to environment and the electric loading condition various dynamo-electric stress that causes that changes lost efficacy, otherwise insulator will lose efficacy, and will damage use and the service life of whole piece circuit.Existing rod insulator generally comprises insulator and metab, and metab is provided with circular hole, and electric wire passes from circular hole.Rod insulator of the prior art is simple in structure, and is easy to use, still, when daily use, because electric wire has certain swing, the wire pair circular hole that can cause passing circular hole causes certain power of pullling, can make metab and insulator come off, and then cause the inefficacy of whole insulator.
Summary of the invention
The purpose of this utility model is to overcome the problem that comes off easily between the rod insulator metab that exists in the prior art and the insulator, and the rod insulator of difficult drop-off between a kind of simple in structure, metab and the insulator is provided.
For realizing above purpose, technical solution of the present utility model is: a kind of rod insulator, comprise the insulator, the metab that have full skirt, described metab is installed in the two ends of insulator, metab and insulator are bonded together by cement glue, fluted on the metab of described insulator one end, inside grooves is provided with a pin hole.
Described cement glue is portland cement.
Be provided with pad between described insulator two ends and the metab.
Described pad is felt paper.
Compared with prior art, the utlity model has following beneficial effect:
1, fluted on the metab in the utility model, inside grooves is provided with a pin hole, electric wire can be wrapped on the latch during use, again latch is inserted in the pin hole of rod insulator inside grooves, when electric wire is swung, electric wire drives latch and can swing in pin hole, greatly reduces the probability that obscission takes place between the metab that causes because of the electric wire swing and the insulator.
2, between insulator two ends and metab, be provided with pad, pad can be selected felt paper for use, when variations in temperature causes STRESS VARIATION between metab and the insulator, pad can play a cushioning effect, make insulator be not easy to occur crackle, whole insulator longer service life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is cutaway view of the present utility model.
Among the figure: insulator 1, metab 2, cement glue 3, groove 4, pin hole 5, pad 6.
Embodiment
Be described in further detail below in conjunction with Fig. 1 and the utility model of Fig. 2:
Referring to Fig. 1 and Fig. 2, a kind of rod insulator, comprise the insulator 1, the metab 2 that have full skirt, described metab 2 is installed in the two ends of insulator 1, metab 2 and insulator 1 are bonded together by cement glue 3, fluted 4 on the metab 2 of described insulator 1 one ends, groove 4 inside are provided with a pin hole 5.
Described cement glue 3 is portland cement.
Be provided with pad 6 between described insulator 1 two ends and the metab 2.
Described pad 5 is felt paper.
During use, because in the utility model on the metab 2 fluted 4, groove 4 inside are provided with a pin hole 5, electric wire can be wrapped on the latch during use, again latch is inserted in the pin hole 5 of rod insulator groove 4 inside, when electric wire was swung, electric wire drove latch and can swing in pin hole 5, greatly reduced the probability of obscission generation between the metab 2 that causes because of the electric wire swing and the insulator 1.In addition, between insulator 1 two ends and metab 2, be provided with pad 6, pad 6 can be selected felt paper for use, when variations in temperature causes STRESS VARIATION between metab 2 and the insulator 1, pad 6 can play a cushioning effect, make insulator 1 be not easy to occur crackle, whole insulator longer service life.The utility model is simple in structure, difficult drop-off, long service life between metab and the insulator.
