[0024] The utility model provides Figure 1 to Figure 4 The lightning protection pillar porcelain insulator with a protective sleeve shown in the figure comprises a core column 1, on which a plurality of evenly distributed sheds 2 are fixedly connected. The bottom end of the core column 1 is glued with a metal cap 14 by means of adhesive, and a groove 15 is provided on the outer wall of the bottom end of the core column 1, and the grooves 15 are arranged in plurality. When the adhesive is filled between the metal cap 14 and the core column 1, the adhesive will penetrate into the inside of the groove 15, and after solidification, the metal cap 14 is not easy to fall off, thereby improving the stability of the connection between the metal cap 14 and the core column 1.

[0025] A threaded rod 18 is integrally formed at the bottom of the metal cap 14 , and a nut 16 is threadedly engaged with the threaded rod 18 . Specifically, the insulator is installed on the cross arm by engaging the threaded rod 18 with the nut 16 .

[0026] The top of the core column 1 is glued with a wire sleeve 3 by adhesive, and a partition 4 is fixedly connected to the inside of the wire sleeve 3. The partition 4 divides the inside of the wire sleeve 3 into a threading cavity 5 and a positioning cavity 6, and the positioning cavity 6 surrounds the outside of the core column 1. In order to improve the stability of the connection between the wire sleeve 3 and the core column 1, a vertical block 12 is integrally formed on the inner wall of the positioning cavity 6, and a slot 17 for the vertical block 12 to be inserted is opened on the outer wall of the core column 1. The vertical blocks 12 are arranged in plurality, and the plurality of vertical blocks 12 are evenly distributed around the inner wall of the positioning cavity 6.

[0027] When the wire sleeve 3 is inserted into the top of the core column 1, the vertical block 12 is inserted into the corresponding slot 17. Since there are multiple vertical blocks 12, the wire sleeve 3 will not tilt, thereby ensuring the accuracy of docking and improving the stability of the connection between the wire sleeve 3 and the core column 1.
