SUMMERY OF THE UTILITY MODEL
The utility model provides a not enough to prior art, the utility model provides a core group flexible connection device designs the arrester core body for flexible connection, can guarantee that the resistance card contact is good, avoids leading to the phenomenon of rupture because of the atress is uneven.
A core group flexible connecting device comprises flexible connecting mechanisms arranged at two ends of a core body.
And the core body is provided with a flexible connecting mechanism.
The flexible connecting mechanism comprises a lower connecting piece and an upper connecting piece matched with the lower connecting piece, and a compression spring is arranged between the upper connecting piece and the lower connecting piece.
The upper connecting piece is a convex connecting block.
The lower connecting piece is a concave connecting block.
The upper connecting piece is electrically connected with the lower connecting piece.
The core body is provided with a core body supporting plate.
The electric connection adopts a spring which can generate telescopic deformation.
Compared with the prior art, the beneficial effects of the utility model are as follows: the connection of both ends of the core body adopts flexible connection mechanisms with the same structure, the flexible connection mechanisms adopt an upper connecting piece, a lower connecting piece and a spring with larger pressing force to press the core body, wherein the lower seat of the lightning arrester is connected with the core body through the flexible connection mechanism, the upper connecting piece is connected with the lower end of the core body, and the lower connecting piece is connected with the lower seat of the lightning arrester; the lightning arrester upper seat is connected with the core body through the flexible connecting mechanism, the upper connecting piece is connected with the lightning arrester upper seat, the lower connecting piece is connected with the upper end of the core body, and a compression spring is arranged between the upper connecting piece and the lower connecting piece. When the core body is in the transportation process or abnormal vibration such as earthquake, the elastic connection of the upper connecting piece and the lower connecting piece, when the core body moves up and down, the compression spring can tightly press the resistance cards of the core body together, and meanwhile, the phenomenon of poor contact does not occur at the two ends of the core body. As a better core flexible connection design, the core is designed to be connected in a segmented mode, the two sections are connected in a flexible connection mode, the flexible connection mode adopts concave-convex connection blocks for connection, and electric connection is achieved through spring conductive strips capable of generating telescopic deformation. The core is during transportation or during unusual vibrations such as earthquake, goes up core and lower core flexonics, sets up down the connecting piece on the lower core, goes up core and sets up down the connecting piece assorted with lower connecting piece down, be equipped with pressure spring between last connecting piece and the lower connecting piece. The phenomenon of poor contact can be prevented, and the core body and the lightning arrester outer sleeve are prevented from being damaged; through the location of core supporting disk between core and the compound overcoat inner wall, prevent that the unsmooth connection of core from deviating from.
