Detailed Description
Referring to fig. 1-3, a take network transformer of lightning protection mechanism, including shell body 1, PCB board 2, connect strip 3 and anti-detonator 301, the internally mounted of shell body 1 has PCB board 2, and the end all is connected with and connects strip 3 about PCB board 2, and the positive surface that connects strip 3 all is connected with anti-detonator 301, and its characterized in that connects the below of strip 3 and all installs protection box 4, and the coupling assembling 5 that has buffering protect function is installed through the screw rod in protection box 4's below.
In this embodiment, the connecting assembly 5 includes an extending groove 501, a nesting ring 502, a spring 503, a shaft rod 504, a connecting seat 505, a lug 506 and a fixing plate 601, the left end and the right end inside the connecting assembly 5 are both provided with the extending groove 501, the nesting ring 502 is slidably embedded below the extending groove 501, the nesting ring 502 is arranged in a square shape, the outer wall of the nesting ring 502 is tightly attached to the inner wall of the extending groove 501, the spring 503 is fixedly connected above the nesting ring 502, and the top of the spring 503 is fixedly connected with the uppermost side of the extending groove 501, so that when the outer shell 1 is impacted by an external force accidentally, the outer shell 1 and the connecting assembly 5 move downwards to push the spring 503 on the nesting ring 502 to compress, the impact force borne by the lower pin 7 is buffered through the compression of the spring 503, and the lower pin 7 is prevented from being broken and damaged by an excessive impact force;
In this embodiment, a lower pin 7 is embedded in the lower portion of the connecting seat 505, the upper portion of the lug 506 is connected to the lower portion of the connecting wire 401, and the lower portion of the lug 506 is tightly attached to the top of the lower pin 7, so that after the upper portion of the lower pin 7 is connected to the lug 506, the connecting wire 401 above the lug 506 can be connected to the connecting bar 3.
